  • My improved machine preferably comprises a 15 supporting frame including a flat, annular, metal plate having a horizontal supporting portion I and depending integral outer and inner flanges 2 and 3 defining therewith an inverted annular channel which affords stifiness with little weight, and is readily stamped from plate metal. Suitable legs are secured to this channel member, preferably by being fastened to the outer fiange so as inefiect to make continuation thereof, while also having parts which traverse the channel and are secured to the inner flange in bracing relation.
  • Each leg preferably consists of a channel shaped stamping having a web portion 4 which is riveted or welded to the flange 2 and lateral flanges 4 which extend toward and are fastened to the flange 3.
  • Figs. 1 and 2 I have shown the portions of these flanges 4 which I are concealed within the annular channel-member as joined by a web 4 which affords still greater stiffness without added expense, though these refinements are optional.
  • the inner flange 3 surrounds and defines an aperture 5 and may well terminate in a fiat lip 3 to facilitate the attachment of the legs and gear-box,
  • a gear-box which here comprises a. top part 6 which is rigidly secured to the channel member of the frame, and a bottom part I suitably secured to the top part.
  • a hollow sleeve 8. Projecting vertically upward from the top part 6 of thisgear-box is a hollow sleeve 8. and mounted in this sleeve is the hub 9 'of a vertical bearingsleeve l0.
  • the liquid-containing casing or tub which has an upright outer wall ll preferably integral with a flat bottom portion I2 which rests on the supporting frame and is apertured at the center for the sleeve l0.
  • the center of this bottom is elevated conically as shown at I3 as set forth in my Reissue Patent No. 18,280, and I have shown its center as provided with a threaded spud l4 clamped thereto by means of an external nut and suitable packing washers I6 and having a threaded gland nut 11 which clamps a packing ring 18 around the exterior of the sleeve If!
  • a clothes-agitating element comprising a hollow shell 20 provided externally with radial liquid-circulating blades 2! and a downwardly flaring part 22 overlying the casing bottom, and provided interiorly with a horizontal web 23 connected to a vertical collar 24 rotatably mounted on the sleeve I0.
  • This shell defines an upwardly flaring surface of revolution inside which I locate a centrifugal extractor.
  • This extractor comprises a container having an upwardly flaring side-wall 25 defining a surface of revolution coaxial with the shell 20 and extending to a level above the top of the wall H.
  • the bottom of this container is formed by a horizontal Web 26 integral with a vertical hollow sleeve 21 which is coaxial with the sleeve l0, and in the form of the invention shown in Figs.
  • the webs 23 and 26 are formed with interfitting pins 28 and sockets 28 whereby the container can be secured to the agitator
  • the sleeve 21 is preferably formed exteriorly with radiating blades 29, and I have also shown the interior of the wall 25 as provided with other blades 25 for a purpose to be hereafter described.
  • an inwardly flaring toprim 30 Carried by the top of the outwardly flaring wall 25 of this container is an inwardly flaring toprim 30, preferably stiffened at its upper edge by ,a roll-rim 3
  • the apertures 32 and flange 33 are both located above the top of the wall ll, so as both to necessitate the employment of a cover during extracting in order to catch the liquid, and hence also to insure safety to the operator, and also to enable convenient disposition of the extracted liquid.
  • This cover comprises a top-portion 35 surrounding the rim 30, and a flange-portion 36 fitting inside the top of the wall ll so as to shed all intercepted liquid inside the same.
  • the top of this cover is preferably formed with a circular opening 31 registering with the container and enabling access to its contents during the washing opera- 1 tion.
  • annular gutter 40 Secured inside this cover and surrounding the container is an annular gutter 40, having an inner wall 4
  • valve-member 41 in this valve casing 011-. erated by a handle 48 above the cover, enables these openings to be employed selectively, so as to discharge the extracted liquid either into the hose 43 or back into the casing.
  • any. stopvalve, or even the lifting of the hose willcompel .the gutter to overflow into the casingas soon as it has become filled with the extracted liquid.
  • the vertical shaft 50 which, in the form of the invention illustrated in Figs. 1 and 2, has its top operatively secured to the sleeve 21 by means of the screw 5
  • the lower end of the shaft 50 projects into the gear-box where it is associated with suitable operating mechanism, preferably that now to be described.
  • Journaled in this gear-box is a horizontal drive shaft 52 driven in any suitable manner as by the pulley 53 belted to a suitable electric motor 49.
  • Carried by this drive shaft are two spiral gears 54 and 55 meshing continuously, the one with a companion gear 56 rotatably journaled on the shaft 56, andthe other with a companion gear 51 journaled on the vertical fixed stud 58.
  • the gear 51 is connected by means of a pitman 59 with a toothed segment 60 journaled on a vertical stud 61 also carried by the gear box and swinging at a lower level than the gear 56.
  • a pinion 62 Rigidly secured to the shaft 50 is a pinion 62 which in its lower position meshes with the segment 6!! and is oscillated thereby, at which position of said shaft the pins 28 and sockets 28 are also engaged as shown in Fig. 1 so that this oscillation is communicated through the extractor container to the agitator.
  • Means are also provided whereby upon the elevation of the pinion 62, and after the consequent disengagement of its driving connection with the segment 60, it shall be brought into driven relation with the pinion 56; and while this may be effected in any one of numerous modes, the simplest arrangement so far conceived, and the one which also affords maximum cheapness combined with maximum manufacturing tolerance is that illustrated in detail in Fig. 6, namely: the pinion 62 is formed with a frusto-conical projection 63 adapted to fit inside the complementarily shaped metal cup 64 which is loosely carried by the pinion 56.
  • This carrying is here effected by three headed screws 65 aflixed to the pinion and loosely traversing apertures in the bottom of this cup, and between the screws are springs 66 located in socketsin the pinion and normally holding the cup-bottom against the heads of the screws.
  • the interior of the cup may be lined with friction material 61.
  • the pinion 56 is provided with a sleeve 68 which rotates loosely on the shaft 50 and also projects freely through a central aperture in the cup where it rests on a supporting ring 69 which loosely surrounds the shaft 56 between the pinion 62 and the cup 64.
  • Slidably mounted in vertical apertures in the pinion 62 are some loose pins 10 whose lower ends rest on an annular disk 1
  • a thrust bearing 12 Surrounding the shaft 56 above the pinion 56 is a thrust bearing 12 which takes the thrust of the springs 66 when the pinion 62 is elevated.
  • Suitable'rneans are provided for raising and lowering the shaft 59 from outside the casing, the means here shown comprising a horizontal rock shaft 15 journaled in a well 16 formed in the bottom part I of the gear casing beneath the shaft 50 and carrying a crank pin I! connected to said shaft by a pitman 18 which extends through the disk II.
  • the upper end of this pitman is provided wtih a spherical (or partly spherical) head 19 connected to this pitman by a reduced neck 89 and located inside anapertured hollow cap 8
  • this pitman supports the thrust of the shaft and weight of the extractor, for which purpose this head is preferably hardened and used with a thrust-ball.
  • the opposite end of the shaft 15 projects beyond the supporting frame and is there provided with a suitable handle 82 by which it may be turned.
  • a shield-plate 83 adapted to prevent access to the operating member 84 of the electric switch which controls the operation of the machine except under proper circumstances and to which is attached the electric cord 84'. It is specially'desirable to prevent the actuation of this switch during the time that the mechanism is connected to the extractor in high-speed rotating relation since the load of starting the extractor from stand-still under such conditions is likely to blow out a fuse or injure the motor.
  • I have shown a completely circular plate having therein an aperture 85 permitting access to the switch when the pinion 62 occupies its intermediate position illustrated in Fig. 6. This circularity also facilitates the employment of this plate as. an indicator-dial, cooperating with a fixed indicating element 86 carried by the supporting frame.
  • one or more of several expedients may be employed, retardation of some kind being desirable to prevent engagement between the pinion 62 and segment 60 while the extractor, due to inertia, is still rotating at high speed.
  • One mode of effecting this is to provide the sleeve 21 with some equi-distantly-spaced narrow radial recesses 90 (of Figs..l to 3) here conveniently formed in the thickened inner edges of the blades 29, and to provide in each recess'acentrifugally displaceable catch having at one end an enlargement 9!
  • a second safety expedient which can be employed either separately or combined with the centrifugal elements just described is to secure the pins 28 to an annular friction-ring 95 rotatably mounted in an annular groove 91 formed in the web 25. If the pins are made of suflicient height to prevent the engagement of the pinion 62 with the segment 69' prior to their entrance at least part-way into the sockets 28, the impossibility of effecting such entrance until the speed of rotation of theextractor has become very small will constitute a substantial protection to the gearing, and the friction of the ring in its groove will effectively brake such revolutions as occur after such introduction.
  • Figs. 9 to 12 Additional expedients for preventing injury by premature engagement are illustrated in Figs. 9 to 12, these-having the additional advantage of providing an extractor which can be removed without impeding the washing operation of the machine.
  • the dasher or agitator is formed as before and the sleeve 21 of the extractor container, instead of being fastened to the shaft, is loosely sleeved about a separate sleeve 99 which is fastened to the shaft and terminates at its lower extremity in a laterally-projecting flange Hill in which the sockets 18 are formed and to which the extractor is detachably secured.
  • the invcnticn shown in Fig.
  • the periphery of this flange is formed with an up-turned lip NH tapered to receive frictionally and in supporting relation a downwardly-projecting complementary flange I02 depending from the bottom of the extractor 25 ably terminates in an interiorly cylindrical socket IM which slidably receives the cylindrical extremity I05 of the sleeve 99, thereby guiding and fixing the axis of the extractor.
  • the sleeve 99 is provided at its lower end with a plain projecting flange IDE having adjacent its inner margin 9.
  • fixed abutment element 0 which in the present embodiment consists of a short cylindrical pin driven into a hole formed for the purpose in flange lull-
  • the bottom of the extractor 25 is formed with an annular depending flange Ill constituting a base by which it can be supported on a table or elsewhere, and to this at one point is affixed a leaf-spring H2 which projects inwardly into a position to engage the abutment I H1 in the manner of a spring pawl.
  • This construction in addition to being inexpensive has the advantage that when thespring pawl is afiixed at the best angle it not only allows the container to overrun the shaft when rotating in the direction shown by the arrow in Fig. 12, but it buckles so as to cushion the shock when the shaft is started to rotate in such direction in advance of-the container.
  • the flange I00 is provided with apertures 28 for the reception of the pins 28 carried by the horizontal web of the agitator when the driving shaft 59 is in its lower or washing position. When the shaft 59 is in its raised position it is continuously rotated in the manner previously described and The upper end of sleeve 21 preferthe container ZS is driven by the engagement of the pawl H2 with the pin 0.
  • the angle between the flanges Illl and I02 is so chosen as to enable the relative slippage sufficicut to protect the gearing, while constituting a brake to bring the container to rest.
  • the container can continue to rotate indefinitely after the re-engagement of the gearing, the spring I I2 merely snapping by the pin H.
  • a split-ring H is preferably snapped into an annular groove formed in the sleeve I'D for that purpose, space for this ring being provided between the top of the hub 24 and the lower end of the sleeve 99.
  • the downwardly-flaring, shape of the flange hereinbefore described causes most of the liquid dripping thereover to fall into the gutter even while the container is at rest, thus preventing contamination of the washing liquid by blucing or rinsing liquids since it is not practical to use the machine even for washing without having the cover in place owing to the splashing produced by the agitator blades. It is obviously infeasible to operate the device as an extractor in the absence of the cover due to the lateral expulsion of the water, wherefore the cover constitutes a very effective safety element.
  • Blueing likewise can be introduced, the clothing mixed thoroughly therein by the washing motion, and the liquid discharged without impeding the washing operation excepting for the brief periods during which the extracting operation is performed.
  • Ordinary domestic laundry articles like towels, clothing, etc. are freed from water in less than a minute to such an extent that additional water cannot be withdrawn from them either by twisting or by a wringer.
  • this container constitutes a convenient mid-week washer or apparatus for washing small and occasional articles of clothing, requiring only a minimum of liquid, and without even requiring the removal of the cover of the main machine.

For purposes of completeness of disclosure 1 shall explain the entire machine herein illus- Patent No. 18,280, December 8, 1931.
trated in spite of the fact that some parts of it are already known through disclosure in certain of my prior applications as for example: Serial No. 694,899, filed February 25, 1924, and issued as Patent No. 1,969,176, on August7, 1934; Serial No. 191,483, filed May 14, 1927, and issued as Patent No. 1,911,903 on May 30, 1983; Serial No. 469,573, filed July 21, 1930, and issued as Patent No. 1,995,926, on March 26, 1935; Serial No. 495,688, filed November 14, 1930, and issued as Patent No. 2,009,111,- on July 23, 1935; Serial No. 480,424, filed September 8, 1930, and issued as Patent No. 2,001,965 on May 21, 1935; Serial No. 534,718, filed .May 4, 1931; and in my Reissue My improved machine preferably comprises a 15 supporting frame including a flat, annular, metal plate having a horizontal supporting portion I and depending integral outer and inner flanges 2 and 3 defining therewith an inverted annular channel which affords stifiness with little weight, and is readily stamped from plate metal. Suitable legs are secured to this channel member, preferably by being fastened to the outer fiange so as inefiect to make continuation thereof, while also having parts which traverse the channel and are secured to the inner flange in bracing relation. Each leg preferably consists of a channel shaped stamping having a web portion 4 which is riveted or welded to the flange 2 and lateral flanges 4 which extend toward and are fastened to the flange 3. In Figs. 1 and 2 I have shown the portions of these flanges 4 which I are concealed within the annular channel-member as joined by a web 4 which affords still greater stiffness without added expense, though these refinements are optional. The inner flange 3 surrounds and defines an aperture 5 and may well terminate in a fiat lip 3 to facilitate the attachment of the legs and gear-box,
Located in this aperture is a gear-box which here comprises a. top part 6 which is rigidly secured to the channel member of the frame, and a bottom part I suitably secured to the top part. Projecting vertically upward from the top part 6 of thisgear-box is a hollow sleeve 8. and mounted in this sleeve is the hub 9 'of a vertical bearingsleeve l0.
Seated on the plate I is the liquid-containing casing or tub which has an upright outer wall ll preferably integral with a flat bottom portion I2 which rests on the supporting frame and is apertured at the center for the sleeve l0. Preferably the center of this bottom is elevated conically as shown at I3 as set forth in my Reissue Patent No. 18,280, and I have shown its center as provided with a threaded spud l4 clamped thereto by means of an external nut and suitable packing washers I6 and having a threaded gland nut 11 which clamps a packing ring 18 around the exterior of the sleeve If! so as to prevent leakage without imposing any strain on the casing-bottom such as would tend to crack enamel therefrom in case enameled metal is used. This construction (whether or not the conical elevation is employed) has a further advantage, as set forth in my application Serial No. 534,718, of enabling the entire working parts to be assembled and tested in advance of the attachment of the casing. Rotatably surrounding the sleeve l0 inside the casing is a clothes-agitating element comprising a hollow shell 20 provided externally with radial liquid-circulating blades 2! and a downwardly flaring part 22 overlying the casing bottom, and provided interiorly with a horizontal web 23 connected to a vertical collar 24 rotatably mounted on the sleeve I0. This shell defines an upwardly flaring surface of revolution inside which I locate a centrifugal extractor. This extractor comprises a container having an upwardly flaring side-wall 25 defining a surface of revolution coaxial with the shell 20 and extending to a level above the top of the wall H. The bottom of this container is formed by a horizontal Web 26 integral with a vertical hollow sleeve 21 which is coaxial with the sleeve l0, and in the form of the invention shown in Figs. 1 and 2 the webs 23 and 26 are formed with interfitting pins 28 and sockets 28 whereby the container can be secured to the agitator The sleeve 21 is preferably formed exteriorly with radiating blades 29, and I have also shown the interior of the wall 25 as provided with other blades 25 for a purpose to be hereafter described.
Carried by the top of the outwardly flaring wall 25 of this container is an inwardly flaring toprim 30, preferably stiffened at its upper edge by ,a roll-rim 3|, and the container thus produced is formed at its level of greatest diameter with liquid-discharge apertures 32, beneath which the exterior of the container is preferably formed with a downwardly and outwardly flaring, annular, liquid-shedding flange 33. The apertures 32 and flange 33 are both located above the top of the wall ll, so as both to necessitate the employment of a cover during extracting in order to catch the liquid, and hence also to insure safety to the operator, and also to enable convenient disposition of the extracted liquid. This cover comprises a top-portion 35 surrounding the rim 30, and a flange-portion 36 fitting inside the top of the wall ll so as to shed all intercepted liquid inside the same. The top of this cover is preferably formed with a circular opening 31 registering with the container and enabling access to its contents during the washing opera- 1 tion.
Secured inside this cover and surrounding the container is an annular gutter 40, having an inner wall 4| which is located beneath the flange 33 and has a diameter slightly greater than said flange so as to enable the attachment and removal of the cover while the container is in place in the machine. Leading from this gutter and also located above the level of the side wall in movement-transmitting relation.-
happens in small apartments, the washing is performed in the kitchen. In the present embodi ment I have illustrated a two-way valve positioned between this pipe and gutter, said valve having a casing 44 formed with two outlet cpenings, one 45 communicating the pipe 42,
and the other 46 discharging inside the casing.=
The valve-member 41 in this valve casing, 011-. erated by a handle 48 above the cover, enables these openings to be employed selectively, so as to discharge the extracted liquid either into the hose 43 or back into the casing. In the absence of such a valve it will be clear that any. stopvalve, or even the lifting of the hose, willcompel .the gutter to overflow into the casingas soon as it has become filled with the extracted liquid.
Slidably and rotatably journaled inside the sleeve 10 is the vertical shaft 50 which, in the form of the invention illustrated in Figs. 1 and 2, has its top operatively secured to the sleeve 21 by means of the screw 5|. The lower end of the shaft 50 projects into the gear-box where it is associated with suitable operating mechanism, preferably that now to be described. Journaled in this gear-box is a horizontal drive shaft 52 driven in any suitable manner as by the pulley 53 belted to a suitable electric motor 49. Carried by this drive shaft are two spiral gears 54 and 55 meshing continuously, the one with a companion gear 56 rotatably journaled on the shaft 56, andthe other with a companion gear 51 journaled on the vertical fixed stud 58. The gear 51 is connected by means of a pitman 59 with a toothed segment 60 journaled on a vertical stud 61 also carried by the gear box and swinging at a lower level than the gear 56. Rigidly secured to the shaft 50 is a pinion 62 which in its lower position meshes with the segment 6!! and is oscillated thereby, at which position of said shaft the pins 28 and sockets 28 are also engaged as shown in Fig. 1 so that this oscillation is communicated through the extractor container to the agitator. Means are also provided whereby upon the elevation of the pinion 62, and after the consequent disengagement of its driving connection with the segment 60, it shall be brought into driven relation with the pinion 56; and while this may be effected in any one of numerous modes, the simplest arrangement so far conceived, and the one which also affords maximum cheapness combined with maximum manufacturing tolerance is that illustrated in detail in Fig. 6, namely: the pinion 62 is formed with a frusto-conical projection 63 adapted to fit inside the complementarily shaped metal cup 64 which is loosely carried by the pinion 56. This carrying is here effected by three headed screws 65 aflixed to the pinion and loosely traversing apertures in the bottom of this cup, and between the screws are springs 66 located in socketsin the pinion and normally holding the cup-bottom against the heads of the screws. The interior of the cup may be lined with friction material 61. The pinion 56 is provided with a sleeve 68 which rotates loosely on the shaft 50 and also projects freely through a central aperture in the cup where it rests on a supporting ring 69 which loosely surrounds the shaft 56 between the pinion 62 and the cup 64. Slidably mounted in vertical apertures in the pinion 62 are some loose pins 10 whose lower ends rest on an annular disk 1| carried by the bottom part 1 of the gear-case. Surrounding the shaft 56 above the pinion 56 is a thrust bearing 12 which takes the thrust of the springs 66 when the pinion 62 is elevated. The
pinion 56 accordingly rotates continuously under the influence of the gear 55, being confined between an upper limit fixed by the bearing 12 and a lower limit fixed by the pins 10. There is never any substantial load on these pins since the only occasion whereon the pinion 56 transmits any power is when it is lifted away from these pins by the pinion 62.
Suitable'rneans are provided for raising and lowering the shaft 59 from outside the casing, the means here shown comprising a horizontal rock shaft 15 journaled in a well 16 formed in the bottom part I of the gear casing beneath the shaft 50 and carrying a crank pin I! connected to said shaft by a pitman 18 which extends through the disk II. The upper end of this pitman is provided wtih a spherical (or partly spherical) head 19 connected to this pitman by a reduced neck 89 and located inside anapertured hollow cap 8| carried by the shaft 50. At its highest elevation this pitman supports the thrust of the shaft and weight of the extractor, for which purpose this head is preferably hardened and used with a thrust-ball. When depressed it 1 has no strain though I have shown a positive down-drawing connection since the presence of wash-water in the shelllll, (which sometimes occurs) produces a dash-pot effect.
The opposite end of the shaft 15 projects beyond the supporting frame and is there provided with a suitable handle 82 by which it may be turned. I have found it desirable to combine this handle with a shield-plate 83 adapted to prevent access to the operating member 84 of the electric switch which controls the operation of the machine except under proper circumstances and to which is attached the electric cord 84'. It is specially'desirable to prevent the actuation of this switch during the time that the mechanism is connected to the extractor in high-speed rotating relation since the load of starting the extractor from stand-still under such conditions is likely to blow out a fuse or injure the motor. In the present embodiment I have shown a completely circular plate having therein an aperture 85 permitting access to the switch when the pinion 62 occupies its intermediate position illustrated in Fig. 6. This circularity also facilitates the employment of this plate as. an indicator-dial, cooperating with a fixed indicating element 86 carried by the supporting frame.
To prevent the premature down-drawing of the shaft 59 one or more of several expedients may be employed, retardation of some kind being desirable to prevent engagement between the pinion 62 and segment 60 while the extractor, due to inertia, is still rotating at high speed. One mode of effecting this is to provide the sleeve 21 with some equi-distantly-spaced narrow radial recesses 90 (of Figs..l to 3) here conveniently formed in the thickened inner edges of the blades 29, and to provide in each recess'acentrifugally displaceable catch having at one end an enlargement 9! adapted to fly outwardly above a certain speed and having at its opposite end an inwardly-projecting hook 92 adapted to overlap a slipring 93 carried by a shoulder 94 with which the sleeve I is formed. This shoulder and ring are located intermediate the oscillating and rotating positions of the extractor, the portion of the sleeve above this level being reduced to permit the centrifugai displacement of these elements to the position shown in Figs. 2 and 2 In case the operator allows the extractor to come to rest before moving the control-shaft these centrifugal elements do not manifest their presence at all, but if an attempt be made to depress the extractor prematurely they catch upon the ring 94 and arrest the movement before the pinion 62 can engage the segment 60. A convenient mode of securing these elements in place is by means of an expansive split ring 95 snapped into an open annular groove 95' formed inside the sleeve.
A second safety expedient which can be employed either separately or combined with the centrifugal elements just described is to secure the pins 28 to an annular friction-ring 95 rotatably mounted in an annular groove 91 formed in the web 25. If the pins are made of suflicient height to prevent the engagement of the pinion 62 with the segment 69' prior to their entrance at least part-way into the sockets 28, the impossibility of effecting such entrance until the speed of rotation of theextractor has become very small will constitute a substantial protection to the gearing, and the friction of the ring in its groove will effectively brake such revolutions as occur after such introduction.
Additional expedients for preventing injury by premature engagement are illustrated in Figs. 9 to 12, these-having the additional advantage of providing an extractor which can be removed without impeding the washing operation of the machine. In both these modifications the dasher or agitator is formed as before and the sleeve 21 of the extractor container, instead of being fastened to the shaft, is loosely sleeved about a separate sleeve 99 which is fastened to the shaft and terminates at its lower extremity in a laterally-projecting flange Hill in which the sockets 18 are formed and to which the extractor is detachably secured. In the form of the invcnticn shown in Fig. 9, the periphery of this flange is formed with an up-turned lip NH tapered to receive frictionally and in supporting relation a downwardly-projecting complementary flange I02 depending from the bottom of the extractor 25 ably terminates in an interiorly cylindrical socket IM which slidably receives the cylindrical extremity I05 of the sleeve 99, thereby guiding and fixing the axis of the extractor.
In the modification illustrated in Fig. 11 the sleeve 99 is provided at its lower end with a plain projecting flange IDE having adjacent its inner margin 9. fixed abutment element 0 which in the present embodiment consists of a short cylindrical pin driven into a hole formed for the purpose in flange lull- The bottom of the extractor 25 is formed with an annular depending flange Ill constituting a base by which it can be supported on a table or elsewhere, and to this at one point is affixed a leaf-spring H2 which projects inwardly into a position to engage the abutment I H1 in the manner of a spring pawl. This construction in addition to being inexpensive has the advantage that when thespring pawl is afiixed at the best angle it not only allows the container to overrun the shaft when rotating in the direction shown by the arrow in Fig. 12, but it buckles so as to cushion the shock when the shaft is started to rotate in such direction in advance of-the container. The flange I00 is provided with apertures 28 for the reception of the pins 28 carried by the horizontal web of the agitator when the driving shaft 59 is in its lower or washing position. When the shaft 59 is in its raised position it is continuously rotated in the manner previously described and The upper end of sleeve 21 preferthe container ZS is driven by the engagement of the pawl H2 with the pin 0.
I With the construction shown in Figs. 9 and 10 the angle between the flanges Illl and I02 is so chosen as to enable the relative slippage sufficicut to protect the gearing, while constituting a brake to bring the container to rest. In the form shown in Fig. 12 the container can continue to rotate indefinitely after the re-engagement of the gearing, the spring I I2 merely snapping by the pin H. In order to avoid any danger that the agitator will be removed along with the extractor due to the seizing of the flanges I0! and I02 shown in Fig. 9, a split-ring H is preferably snapped into an annular groove formed in the sleeve I'D for that purpose, space for this ring being provided between the top of the hub 24 and the lower end of the sleeve 99.
Despite the fact that the interior diameter of the wall 4! of the gutter 40 is of sufllcient diameter to enable the removal of the cover past the flange 33, the downwardly-flaring, shape of the flange hereinbefore described causes most of the liquid dripping thereover to fall into the gutter even while the container is at rest, thus preventing contamination of the washing liquid by blucing or rinsing liquids since it is not practical to use the machine even for washing without having the cover in place owing to the splashing produced by the agitator blades. It is obviously infeasible to operate the device as an extractor in the absence of the cover due to the lateral expulsion of the water, wherefore the cover constitutes a very effective safety element.
Many features of the operation of the machine will have become apparent from the preceding description, but certain peculiar features of operation not heretofore described, and not present in other machines deserve special mention. Due to the employment of a single shaft which carries the container as well as operating the dasher, the container is oscillated at all times that the dasher or agitator is oscillated, and consequently itself constitutes a small sized washer. As rapidly as articles of clothing have become sufiiciently washed they are transferred to this container, then rinse water is introduced therein (either periodically or continuously as may be desired) and the continuation of the oscillating motion to wash the clothing in the outer casing .serves at the same time to thoroughly rinse the clothing in the container. Due to the provision of the annular gutter 4| this rinse water can be allowed to flow continuously from a hose during the rinsing operation, without cooling or diluting the washing liquid, and upon elevation of the container by the handle 82 all the extracted liquid is discharged.
Blueing likewise can be introduced, the clothing mixed thoroughly therein by the washing motion, and the liquid discharged without impeding the washing operation excepting for the brief periods during which the extracting operation is performed. Ordinary domestic laundry articles like towels, clothing, etc. are freed from water in less than a minute to such an extent that additional water cannot be withdrawn from them either by twisting or by a wringer.
Furthermore this container constitutes a convenient mid-week washer or apparatus for washing small and occasional articles of clothing, requiring only a minimum of liquid, and without even requiring the removal of the cover of the main machine.
While I have described with thoroughness a preferred practical embodiment of my invention, it will be understood that a great many changes in different details can be made and I do not limit myself to any of the details herein shown except as the same arespecifically recited in my several claims which I desire may be construed each according to its own limitations and independently of limitations contained in other claims.
