CENTRIFUGAL MACHINE.

SPECIFICATION forming part of Letters Patent No. 605,017, dated May 31, 1898.

Application filed N vember 12, 1897. Serial No. 658,284. (No model.)

panying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to hyd ro-extractors, especially of the class as shown and described in United States Letters Patent N 0. 552,550, of January 7, 1896-.

The object of this invention is to provide a hydro-extractor of the character above referred to with an electric motor, the shaft of the armature of said motor being directly connected to and in alineinent with the shaft of the basket, thus permitting said basket to be' readily and quickly started and tobe brought to the speed required in a very little time, which is of great importance, especially with certain kinds of textile fabrics, as will be well basket, while its fields are carried by the curb or casing, and in the combination and arrange-- ment of the various parts, substantially as will be hereinafter more fully described, and I finally embodied in the claim.

In the accompanying drawings, Figure 1 is an elevation of my improyed hydro-extractor, the curb'or casing and its supporting means being shown in section and Fig. 2, a top plan view of Fig. 1.

In said drawings, a represents the curb, suitably supported by a series of brackets 12 b and intermediate adjustable suspension-rods c, which latter are suitably arranged in the top portions of said brackets and in the bottom flange d of the curb a, respectively. Within the curb or casing a is arranged the perforated basket e, mounted on the vertical shaft f, suitably supported in the bottom of with the shaft f of the basket.

the curb or casing and also in the bearingg,

formed at the inner end of the housingor bracket h, secured toand projecting from the said curb or casing a. The lower portion of said bracket is penetrated bya substantially horizontal rod 2', provided at its outer end with a suitable handle m and at its inner end with a brake-block n, adapted to be moved into engagement with the inclined top flange of the perforated basket 6 when it is desired to stop the rotation of said basket.

On the top portion of the bracket 72. is adjustably arranged the arm 0, carrying the fields p p of the electric motor, which fields are parallel with the bottom of the curb or casin g and cooperate with the armature q, mounted on the shaft 3,, which shaft is in alinement and suitably coupled or connected The shafts f and 8 therefore practically constitute a single jointed shaft. The other end of the shaft s of the armature q is supported in the bridge t, projecting from the fields p p, as clearly shown in the drawings. The brushes u for the commutator o are of any well-known construction and are carried by the bridge t in any desired manner.

From the foregoing it can be seen that the armature and its shaft are carried by the shaft of the basket, and the weight of said a1- mature is thus uniformly distributed around the axis of the basket, and that there is no undue strain exerted in any special direction upon the said shaft, as is the case when operated by a belt and grooved pulley or by other well-known means. By this arrangement when the motor is connected with thesource of electricity and the current is turned on the basket will' be atits full speed in comparatively little time, and can be just as readily stopped, especially when the brake n is applied after the currenthas been shutoff.

The machine can be quickly set' up and readily connected with any convenient source of electricity and can be run with the least jar or tremor to the floor and at uniform speed and with very little noise.

Having thus described my invention, What I claim as new, anddesire to secure byLetters Patent, is-

In a hydro-extractor, the combination with a movablysuspended curb or casing, an inwardly-projeoting bracket secured to the top edge thereof, bearings in the free end of said bracket, an inwardly-projecting arm mounted on said bracket, eleetromagnets-and a pair of horizontally-extending fields carried by said arm, the latter being arranged above the bearings, a bridgeeonnecting said fields and suitably-mounted and arranged brushes and commutators, of a vertical jointed shaft stepped in said curb or casing and journaled in said bearings and in the bridge, a basket.

carried by the lower member of, said shaft and having an inclined t'op flange and an arma' tnre carried by the upper member of said November, 1897.
