COP-FORMING MACHINE.

Specification of Letters Patent.

Patented J an.6, 1914.

Original application filed December 5, 1910, Serial No. 595,818. Divided and this application filed May 1,

being wound upon a cop tube, spindle, spool,

or bobbin in the usual way, iscompacted within a casing consisting, by preference, of

a flexible tube of textile material, this casing being open at either or both :ends and pre erably at both ends, in order that the yarn may be drawn from either end of the same. The yarn is compacted within this casin by feeding it into one end of the same, and: as it accumulates, subjecting it to the action of a reciprocating rammer, the lower end of the casing being temporarily closed during the filling operation and said casing being also, by preference, supported during such operation by means of a surrounding and relatively rigid holder.

In the accompanying drawingsFigure 1' is a sectional view of a cop for loom shuttles made in accordance with my invention; Fig. 2 is a View partly in front elevation, and partly in longitudinal vertical section, of my improved machine for producing such cops; Fig. 3 is an end view of the machine, looking in the direction of the arrow m, Fig. 2; Fig. 4 is a view of said machine, partly in endelevation and partly in transverse section; Fig. 5 is a transverse section on an enlarged scale of the devices whereby the yarn which constitutes the cop is compressed or compacted in the casing of the same; Fig.

Serial No. 624,437.

3 which has, at one end, any suitable means for applying power thereto, such means, by preference, including a clutch of any appropriate character whereby the rotation of the shaft 3 can be readily started or stopped, such clutch, by preference, being under control of a lever 4 operated by a longitudinal rod 5 extending across the front of the machine, whereby the operation of the machine can be started or stopped from any point within the length of the machine.

At each end of the machine the shaft 3 has a spur wheel 6, which meshes with a spur Wheel '7 mounted so as to be free to turn on a shaft or stud carried by the corresponding end framel of the machine, and secured to this spur wheel in any desirable manner is a disk 9 having a crank pin 10 engagin the lower end ofa rod 11 whose upper end engages a pin 12 projecting from the end of a longitudinal bar 13, the latter being vertically guided in slots 14 in the end frame of the machine.

Suspended from a bar 13 are a series of rods 15 each of which is provided at its lower end wlth a rammer 16, each of the rods being threaded at its upper end and provided with a nut 17 bearing upon the top of the bar 13, whereby, when the latter is raised, it will raise all of the rammers 16 and when it. descends will permit said rammers to drop.

Mounted upon the lowermost of the longitudinal bars 2 at the front of the frame is a carrier comprising a base bar 20, a top bar 21, end bars 22, and a longitudinal bar 23, this carrier serving for the retention and support of a number of cylindrical holders 24-, into which are fitted the textile casings 25 for the cops, the holders 24 being composed of paper or other material which will combine lightness in weight with sufficient strength to properly retain and support the casings 25, the latter extending from top to bottom of the holders, and, by preference, overlapping the tops of the same, as shown in Fig. 5, and being confined by means of a funnel 25, as shown in Figs. 4 and 5.

Surrounding each' of the rods 15 and rammers 16 is a funnel 26, and the entire series of funnels is mounted in a box or frame 27 which has, at each end, studs 27 guided in vertical slots 2'? in the corresponding end frame 1 (see Fig. 2) whereby said box or frame 27, while confined in position longitudinally and laterally, can be raised and supported in nels 25.

lowered to a limited extent by means of levers 29 passing through openings in the box or frame'27, as shown in Figs. 2 and 4, thereby raising or lowering simultaneously the entire set of funnels 26.

When raised, the-box or frame 27 can be the elevated position by means of hangers 50, depending from one of the bars 2 and slotted for the reception of eyes or other projections 51 on the box 27.

When the carrier with its holders 24 and their contained cop casings 25 and funnels 25 is inserted in place at the front of the machine, the box 27 is released from the hangers 50, and dropped so as to rest on the tops of said funnels 25*, each of the funnels 26 being then in line with one of the fun- If now, the yarn is fed down- Wardly through the funnels 26 and 25 and into the co casing, it will dispose itself in the form 0 folds or coils, and, when the bar 13 is vertically reciprocated, these folds or coils will be compacted by the weight of the rammers 16 on the descent of the latter, each of the rammers being always lifted to the same height but the drop of the rammers being gradually shortened as the yarn accumulates in the cop casing. The means for feeding the yarns into the cop casings comprises three rolls 30, 31 and 32 and an endless apron 33, the upper run of the latter passing between the upper roll 30 and the rolls 31 and 32, so as to provide a relatively long contact of the yarn with the upper roll and insure the proper and uniform feeding of the yarn to its proper casing, each yarn, as it enters the machine, passing over the top of the roll 30 from a uide 34 at the front of the machine and eing prevented from traveling around said roll 30 beyond the proper point of delivery by means of a doctor plate or clearer, 35, as shown in Fig. 4. The apron 33 may be dispensed with if the rolls 30, 31 and 32 are properly surfaced to insure the necessary grip upon the yarns.

My invention has been designed especially for the formation of copseomposed of strips of chenille, which are used as weft threads in weaving certain types of fabrics. These strips are of greater width than thickness, and it is very desirable to have them lie fiat or withouttwist in the cops in order that they may deliver straight, and render it unnecessary for the weaver to straighten them as they are being set preparatory to being beaten up'into the web. For this reason, I provide the guides 34 with oblong eyes, as shown'in Figs. 2 and 7, these eyes being but little wider than the thickness of the chenille strip, whereby the latter is compelled to pass through the eyes in a straight condition, consequently if there is any twist in the strip when it reaches the eye, this twist will be eliminated before the strip can pass through the eye.

' All of the rolls 30, 31 and 32 are d! iven at the same surface speed by means of interineshing spur gears 36, 37, 39 and 40, carried by the roll shafts at one end .of the machine, rotary movement being imparted to the shaft of the roll 30 from the driving shaft 3 by means of a belt 41 and pulleys 42 and 43, as shown in Figs. 2 and 3.

\Vhile I prefer to connect the suspension rods 15 of the rammers 16 to the lifter bar 13 so that each rammer will be free to drop independently of the others, I may, in some cases, secure all of the rods 15 to the lifter bar '13 by providing said rods with nuts 17 both above and below the lifter bar, as shown in Fig. 6, the crank-operated connecting rod 11, in this case, having a slotted yoke 44 for the reception of the pin 12 so that While the bar 13 will always be lifted to the same height on each stroke.of the crank pin 10, the drop of the bar and its suspended rammers may become gradually less and less as the yarns accumulate in the cop casings.

I claim:

1. The combination, in' a cop-forming machine, of a carrier for a plurality of casings, means for feeding yarn to each casing, a

plurality of funnels interposed between the feeding means and the casings and serving to direct the yarns into the latter, a plurality of rammers for compacting the yarns as they accumulate in the casings, means for raising and lowering the plurality of funnels and means for supporting the funnels when they are not .in operative relation with the casings. y

2. The combination, in a cop-forming machine, of a carrier for a cop casing, means for feeding yarn to said casing, and a rammer for compacting the arn as it accumulates in the casing, said ceding means comprising a series of rollers, an endless apron interposed between them, the rollers being so disposed as to cause relatively extended contact of the apron with one of the rollers.

3. The combination, in a cop-forming ma chine, of a carrier for a plurality of casings, means for feeding yarn to each casing, a plurality of funnels interposed between the feeding means and the casingsand serving to direct the yarns into the latter, and means for supporting said funnels so that they can be raised and lowered as a unit.

4. The combination, in a cop-forming machine, of a carrier for a plurality of casings,

-means for feeding yarn to each casing, a

plurality of funnels interposed between the feeding means and the casings and serving supporting-said funnels so that they can be raised andlowered as a unit, and means for 12-5 to direct theyarns into the latter, means for retaining said funnel support in its raised position.

5. The combination, in a cop-forming machine, of a carrier for a plurality of casings, means for feeding yarn to each casing, a plurality of funnels interposed between the feeding means and the casings and serving to direct the yarns into the latter, a vertically guided box in which said funnels are mounted, and a lever for raising and lowering said box.

(3. The combination, in a cop-forming machine, of a carrier for a casing for the cop,

means for feeding yarn into the casing, a rammer for compacting the yarn as it accumulates in the casing, and a yarn guide having an oblong eye whereby yarn in the form of a chenille strip Will be straightened on its way to the feeding devices.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing Witnesses.
