Specification of Letters Patent.

raremeduui 25, 1922.

To all whom it may concern:

Be it known that 1. ROBERT E. Hmns, a citizen ot theUnited States, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Spinning, Doubling, and Twisting Machines, of which the following is a specification.

This invention relates to spinning, d0ubling and twisting machines, and it has for its principal object to improvemachines of this class of the particular kind set forth in: the Seymour Patent No. 909,466; other objects will appear hereinafter.

In the drawings,

Figure 1 is a sectional view on; line 1-1,

Figure 2 is a front elevation of a spinning, doubling and twisting unit;

Figure 3 is a section on line 5? 3, Fig. 10';

Figure 1 is a fragmentary side elevation of what is shown in Fig. 3';

Figures 5 and dare sectional details of the feed pulley; Y

Figure? 'sa front elevation and Figure 8 a tront-to-rear section of the spindle group, the section of the latter figure being on line 8-8, Fig. 9

Fig. 9 is a plan of the spindle-group;

Figure 10 is a plan. of the two assembled arms for the spinning spindles; and

Figures 11 and: 12 show the respective arms in plan and side elevation.

The two spinning spindles are designated 1 and the twisting spindle is designated 2, 3 being the spindle rail in which a number of groups of spindles 1 andQ will be mounted. The whirls of these spindles are arranged so that the driving belt A. passes between them, or back of spindle 2 and in front of spindles 1. The flanged socket -11 affording a support for spindle 2 may be held in rail 3 in the usual way, as by nut and spring 6 on its depending tubular shank 4:. The annularpart 5" of a bracket 5.projecting rearwardly from the rail rests on and is pinnedtat 5 Fig. 8) to the rail, being penetrated by shank 4. Be tween this and the flange at of the socket are journaled, also penetrated by said shank, the bearing portions 6 of arms 6- which at their free annular ends 6 carry the flanged sockets 7 and thereby form supports for the spindles 1,. the shanks? of which sockets are held in: said annular ends 6 by the nuts 8 and springs 9.v Such support for one spindle 1 has journaled-v therein on. a vertical axis a roller 10 to bear against the front face of the belt. W hen the supports for the spindles 1 swing, forward the whirls of the spin.- dles 1 will press the belt against the whirl of spindle 2-, and? when: they swing back the whirls of spindles 1 clear the belt, which is also then withdrawn from. thewhirl of spine dle 2 by the roller 10; Annular part 5 of bracket 5 is embracedby the coilsof a spring 11"whicli1 is kept from turning thereon by having: an eye 11 formed therein engaged by a lug 5" on said: part, the ends of the spring being engaged insuitable holes 6-" in the arms 6: this spring tends to hold the arms pressed forward, so that the spindles will: be driven (:posi-tion of Fig. 9').

Anupright rod 12 is guided at its lower end in the bracket 5, being subject totheupward pressure of a. spring 13- interposed between the bracket and: a casting 14 onthe rod having arms 14 which: project under the whirls .of the spindles and may act thereon asbrakes, Fig. 9,,said casting forming; in effeet a cam-fork by having depending .converging pins 14 which slide more or less freely in holes 6" in the arms 6; the upper end of the rodis. guided, in a slot 15 of the fined bracket 15 and has a shoulder 12 to catch under the bracket and hold down the rod, against the tension of spring 13 When the rod' is down it permits the spring 11 to hold the, arms 6*pressed forward, so that the spindles will bedriven; when. the rod is released and rises under the pressure of spring 13 the convergent pins of its cam-fork retract the arms 6, clearing the spindle whirls from the belt.

The threads extend up from bobbins on the spindles 1, by which they are spun, through individual guides 16011 rod 12,.then back of and over guides 17 on bracket 15, then through the eyes of individual fallers 18 and back ovcra common guide 17 on said bracket, then, being new doubled, down. and (with one or more turns) around the feed pulley 19, then through a guide 20 on the rod, and: finally through a traveller 21 which runs on a ring 22 on the suitably reciprocated ring-rail 22', being wound on the bobbin; on spindle 2, of course after undergoing twisting together. The pulley, which is mounted on the rod to rotate in a vertical plane, has formed or otherwise caused to rotate with it pinion 23 which overhangs and is adapted when the rod is in the locked down position to mesh with apinion 24L driven by the suitably rotated constantly going horizontal shaft 25 on which is fixed a tappet or trip member 26. On a horizontal axis 27 (on which the fallers are pivoted) there is pivoted in the rod a dog or lever 28 whose longer or heavier arm has a rearwardly and downwardly beveled end 28 and normally holds the dog upright (position of Pig. 1) and whose other arm has ahorizontal stud 2S opposite the fallers. The dog may swing into contact witha stop 28" (Fig. l) on rod 12 when a faller, being re leased by the breaking of its thread, falls and so actuates the dog, and in this position the beveled end of the dog will be struck by tappet 26, so that the rod will be forced forward and, its shoulder being disengaged from bracket 15, be then elevated by spring 18, thus to clear pinion 28 from pinion 24:, so that the draft on the thread is discontinued, and withdraw the spindle whirls from contact with the belt. To reset the parts the operator, after piecing together the ends of the thread and reestablishing it in working relation to the feed pulley and faller, leaving the latter held up by the thread as before, has only to push the rod down and back into re-locked relation to bracket 15. The extent of upward movement of the rod is determined by contact of adjusting nuts 14!, screwed on the rod, with the bracket 5. It will be noted that when the rod is in locked-down position it is in effect clamped between the spring 13 and bracket 15, so that a quite definite gearrelation is maintained between the pinions 23 and 24. Also that the device 26 has nothing to do with actually moving the spindles clear of the belt; this function is performed by the spring 13, which, moreover, maintains a certain control over the rod when the operator moves it to resetting position. These are factors considerably increasing the efficiency of the machine.

To insure proper gripping on the thread the feed pulley 19 has the novel construction illustrated in Figs. 5 and 6, where the gear 23 is incidentally shown as an integral part of it. The pulley, which is a metal die-casting is formed with a hub 19 a disk-like body part 19". and a rim 19 which latter forms lateral flanges at both sides, the flange at one side having the teeth of gear 23 and the flange at the other side have circumferential ribs 19 forming a V-shaped groove to receive the thread. Recesses 19 are formed at regular intervals in the latter flange, openinglaterally into the same and communicating with the groove, and in these are driven inserts 29 of yielding thread-gripping material, such as cork, upon which the thread bears. These inserts add greatly to the tractive action of the pulley, and when worn may be readily replaced. Further, the rim-flange containing these inserts may have an undercut 30 communicating with the groove ant adapted to rereive a knife or hook as shown in Fig. 6, whereby to either cut or catch and break a coil of thread that may be left wound on the pulley and would be otherwise difficult to remove on account of the narrow V shaped groove.

In combination, a spindle, a support therefor, a pair of spindles, a pair of supports for said pair of spindles pivoted conccntrically with the first support, a driving belt arranged between the first spindle and the pair of spindles, and means to move the pair of supports hack and forth together in reverse directions to cause the spindles to grip the belt or clear the same.

2. In combination, a spindle, a support therefor, a pair of spindles, a pair of supports for said pair of spindles pivoted conccntrically with the first support, a driving belt arranged between the first spindle and and the pair of spindles, and a spring urging the pair of supports each in the direction to cause said pair of spindles to eoact with the first spindle to grip the belt.

3. In combination, a spindle, a support therefor, a pair of spindles, a pair of supports for said pair of spindles pivoted conccntrically with the first support, a driving belt arranged between the first spindle and the pair of spindles, and means to move the pair of supports back and forth together in reverse directions to cause the spindles to grip the belt or clear the same including a spring extending around the first support and engaged with and normally urging each of the other two supports in one direction.

4. In combination, a spindle, a support therefor, a pair of spindles, a pair of supports for said pair of spindles pivoted conccntrically with the first support, a driving belt arranged between the first spindle and the pair of spindles, a spring urging the pair of supports each in the direction to cause said pair of spindles to coact with the first spindle to grip the belt, and means to move said pair of supports each in the opposite direction.

5. In combination, a supporting structure, an upright spindle, a support for the spindle movable in said structure, a belt to drive the spindle toward and from which said support is movable substantially horizon tally, means to move said support toward and from the belt including an up-a-nd-down movable devrce having a cam to engage the support and normally urged but held by said structure against movement in one direction and also movable to clear said structure, and means, controlled by the thread, to move said device clear of said structure.

6. In combination, a supporting structure, an upright spindle member, a belt member to drive the spindle member, one of said members being movable into and normally held in contact With the other, an up-and-downmovable device normally urged but held by said structure against movement in one direction and also movable to clear the same, said device having means When so moved to cam one of said members away from the other and also means to brake the spindle member, and means, controlled by the thread, to move said device clear of said structure.
