DOUBLlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 374,055, dated November 29, 1887..

Application filed May 18, 1887. Serial No. 238,572. (No model.)

p which- Figure 1 is a perspective diagram illustrating the essential parts of the machine. Fig. 2 is a view,partly in section and partly in elevation,of an organized machine constructed in accordance with my invention. Fig. 3 isaplan view of said machine. Figs. 4 and 5 are detached views of parts of the machine, and Fig. 6 a side view showing a slight modification in one of the elements of the machine.

In my improved machine I simultaneously effect the doubling of the strands and the winding of the doubled yarn upon a spindle to form the cop.

Referring to Fig. 1 of the accompanying drawings, 1 represents the spindle upon which the cop is to be wound, said spindle being of square or other polygonal form in cross-section and being free to slide in a sleeve, 2,which is adapted to suitable bearings in standards 3 on the fixed frame '4 of the machine, and is provided with a fast pulley, 5, and loose pulley 6, for receiving the driving-belt.

The. strands 8, which are to form the doubled strand 9, are drawn directly. from the skeins or hanks 10,and pass between an upper feedroll, 11, and lower feed-rolls, 12 and 13, and thence through a guide-eye, 14, to a traveler, 15, on a ring, 16, carried by the pivoted end of one arm of a traverse lever, 17, which is mounted upon a shaft or spindle, 18, the other arm of thelever havinga slotted 1ink,19, which embraces a shaft, 20, carrying a heart-cam,21, the latter acting upon an anti-friction roller, 22, on the link,which roller is maintained continually in contact with the surface of the cam by means of a coiled spring, 23, connected at one end to the link and at the opposite end to a fixed eye on the frame. This gives a short traverse for carrying the yarn from the bottom to the top of the cop-nose. the slow retraction of the spindle, so as to effect the gradual ad-, vance of the successive courses of yarn upon the same,being effected by means of a frame, 24, the upper bar of which is free to slide longitudinally and to swing in bearings in the standards 3, and is connected by a link, 25, to the rear end of the spindle 1, said link having a set-screw, 26, adapted to a groove, 27, in the top bar of the frame 24, as shown in Fig. 4,so that while the spindle 1, must partake of any longitudinal movement of said frame the latter can be swung up or down without restriction. The connection between the link 25 and the spindle 1 is also similar to that shown in Fig. 4, so that said spindle is free to rotate.

The lowerbar of the frame 24 has a rack, 28, with which engages a worm, 29,0n a shaft,30, adapted to hearings in brackets 31 on the frame 4 and driven at a slow rate of speed, so that as the yarn is laid upon the cop the spindle 1 will be slowly retracted and the successive layers of yarn properly disposed thereupon.

When the cop is fully formed, the frame 24 maybe swung upward by means of a handle, 32, so as to release the rack 28 from the control of the worm 29, the pivoted guide-eye 14 and the pivoted upper end of the traversearm, with its ring and traveler, being then thrown d9yvn,as shownin Fig 5,so as to permit the doffing of the cop from tl e spindle. After the cop has been doffed,the pivoted guide-eye and the ring are restored to their former positions, the spindle is drawn forward, and the frame 24 again swung down, so as to effect the re-engagement of the rack with the worm preparatory to a repetition of the operation.

It will be seen that by the use of the ring and traveler on the traverse-motion device the twisting or doubling of theindependent strands is effected simultaneously with the winding of the doubled yarn upon the spindle to form the cop, all preliminary spooling operations being dispensed with.

That portion of the spindle 1 on which the yarn is wound should in all cases be of such diameter. that the yarn in passing from the traveler to the spindle will assume such an angle as to insure the pulling of the traveler around the ring.

IOU

In Figs. 2 and 3, which show the complete machine constructed in accordance with my invention, 4 represents the fixed frame, which has suitable bearings for the reception of the driving-shaft 35, the latterhaving a pulley,36, which receives the belt from any available counter-shaft. The shaft 35 also has a pulley, 37, which receives a belt, 38, the latter, by

means of any suitable form of belt-shifter, be-

ing applied either to the fast pulley 5 or the loose pulley 6 on the sleeve of the spindle 1. On the shaft 35 is also a pinion, 39, which engages with a spur wheel, 40, on a sleeve, 41, carried by a stud, 42,011 the frame, said sleeve having a pulley, 43, which receives a belt, 44, adapted to a pulley, 45, on a shaft, 46, thelatter having a bevel-wheel, 47, engaging with a bevel-pinion, 48, on the worm-shaft 30. The shaft 46 is also provided with a pulley, 49, which receives a belt, 50,driving a pulley. 51, on the cam-shaft 20, and on the driving-shaft 35 is a pulley, 52, receiving a belt, 53,which is adapted to a pulley, 54, on a sleeve carrying a pinion, 55, which engages with a spur wheel, 56, on the shaft of the lower feed-roll l2, spurpinions 57 and 5S, and an intermediate spurwheel, 59, transmitting movement to the other of the lower feed-rolls. 13. The hanks are carried by the reels 60, which are adapted to bearings in brackets 61 on the frame of the machine.

The pivoted upper end of the arm of the le ver 17,which carries the ring 16, is acted upon by a spring, 65,which tends to maintain said pivoted end either in the position shown in Fig. 2 or in the depressed position shown in Fig. 5.

If desired, the ring 16 and its traveler may be carried by a sliding bar, 70, operated by a cam, 21, and lever 17, as shown in Fig. 6, instead of being applied directly to the lever, as in Figs. 1 and 2.

I claim as my invention- 1. The combination of the spindle and means for rotating and slowly traversing the same,with a traverse-motion device having a ring and traveler, and with means for operating the said traverse-motion device, all substantially as specified.

2. The combination of the spindle and mechanism for rotating and slowly traversing the same, a traverse-motion device having a ring and traveler, a set of feed-rolls, and means for operating said feed-rolls and the traversemotion device, all substantially as specified.

3. The combination of the spindle and mechanism for rotating and slowly traversing the same, a traverse-motion device having a ring and traveler, a set of feed-rolls, hangers for two or more sets of skein-reels, and means for operating the feed-rolls and traverse-mo tion device, all substantially as specified.

4. The combination of the spindle and worm and means for rotating the same, with a swinging frame connected to the spindle and having a rack movableinto or out of engagement with the worm, all substantially as specified.

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