T0 all whom it may concern:

Be it known that I, FRANCIS SEYMOUR, a citizen ofthe United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Machines for Doubling, Twisting, and Quilling, of which the following is a specification.

This invention relates to machines employed in those treatments on thread or yarn, known as doubling, twisting and quilling.

The invention consists in certain improvementsy in these machines whereby quilling alone, without doubling or twisting, or quilling with twisting (compound or single) or with doubling and twisting, may all be accomplished-in one and the same machine; whereby the traverse may be regulated to vary the pitch of the windings of the quill or other wound package; and whereby the diameter of the wound package may be varied as the circumstances affecting lthe connection in which it is to be used may require.

The invention further consists in several other features involving improved constructions and arrangements of parts whereby to increase the output materially, improve the quality of the product and attain a higher degree of efficiency in general, salient among which latter features may be mentioned those involving the spindle groups and the mechanism for stopping the operation with 'respect to any particular thread should any irregularity attending the same arise.

The invention will lbe found fully illustrated in the accompanying drawings, wherein,

Figure 1 is an elevation of one side vof that end-portion of the machine at which the power is introduced, certain parts being removed; Fig. 2 is an elevation of the sameV side `of the other end-portion of the machine, certain parts being removed; Fig. 3 is an end elevation` of what is shown in Fig. 1; Fig. 4 an end elevation of what is shown in Fig. 2; Fig. 5 is a horizontal sectional View taken just above the plane of-the spindledriving belt, certain parts being removed; Fig. 6 is an enlarged detail view showing one of the spindle units and the means associated therewith for eiiecting the traverse and the advance of the thread longitudinally of the winding axis in the building of the package, the means for causing the feed of the thread or yarn to the receiving spindle, and the means for stopping the rotation of the spindle, the feeding of the thread and the traverse motion upon the breaking of a thread; Fig. 7 is an enlarged detail view, in plan, of one of the spindle-rails, the spindledriving belt, one of the pivoted spindle units and a part of the means controlling the movements of the latter; Fig. 8 is an enlarged detail view of a part of the means for advancing the thread longitudinally of, the aXis of winding, as seen from the right of one of the spindle units in Fig. 1;Fig. 9 is a plan view of what is seen in Fig. 8; Fig. 10 is a plan view of a detail of Fig. 3, on a somewhat smaller scale; and, Fig..11

is a detail view illustrating the fallers for` one of the spindle groups.

a designates a series of uprights all substantially the same in construction and secured together by the two spindle-rails b,

two tubular braces c and other rails and shafts (some of which require no special mention and others of which will be hereafter referred to) so as to form the frame of the machine.

ln a plane somewhat above the spindlerails b is disposed the continuous spindledriving belt d. Referring to Fig. 5 it will be seen that thisbelt is so maintained as to produce thereof two loops df d2 one within and parallel with the other. At one end of the machine the loop d extends around the large driving pulley e, and the loop d2 around the two idlers f; at the other end of the machine'the loops of the belt are maintained by the idlers g, the parallelism between the two loops being maintained by the idlers la. The pulley e is carried by the vertical shaft i journaled in the brackets j and lc, while the idlers f are carried by the bracket l and the idlers g are carried by a bracket m movable toward and from the pulley e and idlers f, being supportedon fixed studs 'a projecting from the adjacent end upright aand normally forced from said upright by a lever o fulcrumed in a bracket 72, bearing at its upper end against the bracket m and subjects to the pull ofI shifted vertically, to shift the belt from the onetothe other of the pulleys s, by manipulating a lever operatively connected with said stand and provided with a pin y to be entered into holes z in the lever and bracket 7" to hold the former at the position to which it is adjusted. The stands u and fw are so constructed that their positions in the brackets y" may be interchanged to adapt them to the belt whether it is running one way or the other.

At suitable intervals tubular posts 2 are pivoted on the stems 3 secured to the spindle rails by nuts 4. The upper end of each stud is a head 5 on which is journaled an idler 47 which stands between, and whose diameter is equal to the space between, the adjoining parallell portions of the loops d and alzof the belt (Fig. 7 Integral with the post 2 is a carrier 8 in the form of a plate. This carrier is apertured to receive the bearings 9and 10 of spindles 9 and 10, the spindle 9 standing relatively outside of the adjoining stretch of thevloop d of the belt and 4the spindle 10 normally inside -of the adjoining stretch of the loop d? of the belt. The plate may swing in a horizontal plane on stem 3 as an axis to bring both spindles into Contact with the belt, ('at that time supported as to both stretches against their pressure by the idler 7) whereupon they will rotate in the same direction, orl out of contact therewith, it being normally held in the first-named position by a spiral spring l1 connecting it with a suitable part of the frame. Between the two stretches of the loops d and 'd2 ofthe belt the plate is formed with an aperture 12 into which the spindle 10 may be shifted, in which position, when the spindles are operatively engaged with the belt, they will rotate in reverse directions. 1

13 (Figs. 6 and 7 is a post secured in and projecting upwardly from the carrier 8 and penetrated by a vertical rod 14 splined in said post, the said rod carrying two horizontal arms 15. In these arms is journaled a threaded shaft 16 which has slight vertical movement, being cushioned-by a spring 17 coiled about its lower end and interposed between a shoulder 18 of the rod and the lower arm 15; to `the upper end of the threaded shaft 16 is secured a friction-wheel 19. Penetrated by the rod 14 is a carrier in the form of a plate 20 having an aperture 21 for the spindle 9, the said aperture being surrounded by a ring 22 on which is a thread guide 23 of the so-called traveler type. Coacting half nuts 24 vare pivoted to the carrier 20 and normally held engaged with the threaded shaft 16 by a spring 25. By grasping the half nuts at the points indicated by the arrows in Fig. 9, the carrier may be manually moved to any position on the threaded shaft 16. The structure including the rod 14, the rotary shaft journaled in the arms 15 and carrying the friction-wheel 19, and the carrier 20 is adapted to be reciprocated for the purpose of imparting the necessary traverse to the thread as it is wound around the spindle 9 as an axis, and, during such reciprocations, intermittent rotary impulses are imparted to the shaft 16 so that the carrier advances upwardly relatively to the spindle and rod 14 as the winding proceeds.

Describing, now the manner in which the traverse motion mentioned is accomplished, coinciding with each winding unit there are secured to opposite sides of the braces o pairs of brackets 26 in one of which in each pair is fulcrumed a curved lever 27 aifording a bearing for a pinion 28 and a heart-cam 29 fixed to rotate together, the pinion 28 meshing with and being Sup. ported by a pinion 30 fixed-on a shaft 31 which is journaled in the several uprights a. The rod 14 which penetrates the spindle rail b (the opening therefor in the spindlerail being suiciently large- Fig 6-to allow said rod to swing with the carrier 8) carries at its lowerv end a roller 31 which rests upon the cam, the periphery of the roller being faceted so that, in view also of the eccentric mounting thereof, the rod will be elevated different distances each series of revolutions of the cam requisite to effect one complete revolution of the roller, the object being to produce crossed windings of the yarn or thread.

Referring, now, to the manner in which the carrier 20 is elevated relatively to the spindle to advance the thread in the winding, 32 is a rotary horizontal shaft journaled in the upright a above the spindles and carrying the friction-wheels 33, each being adapted to contact with a frictionwheel 19 to impart a rotary impulse thereto whenever. in the up and down motion of the rod 14- and the parts it carries, the friction wheel 19 is brought in contact with the friction-wheel 33; it will be apparent that the cushioning of shaft 16 not only relieves the shock occurring each time the contact between the friction-wheels occurs, but renders such contact highly efiicient to transmit the motion from the one to the other of said friction wheels. Each friction-wheel amaca? 33 may be secured to the shaft in such manner as to be adjustable toward and from the aXis of rotation of friction-wheel 19 (in the vertical plane of which the shaft 32 is disposed) to vary the extent of movement imparted to the threaded rod 16 each time the friction wheels engage each other.`

There being two sets of spindle groups and their accessories above described, one at each side of the machine, as usual, there are of course two shafts 31 and 32, as shown. Between the two shafts 32', journaled above the shaft 32, and on a stub-shaft 34 (Fig. 10) projecting from the end upright appearing in Fig. 1 is journaled a rotary member comprising a pinion 35 and a bevelsgear 36, the rotary movement of said member being transmitted to the shafts 32 through transmission pinions 37 meshing with the pinion 35 and pinions 38 on said shafts. rllhe driveshaft z carries a pinion 39, and j ournaled in the bracket lo is a rotary member comprising a bevel-pinion 40, meshing with bevel gear 36, and a pinion 41 g 42 is a transmission pinion meshing with pinions 39 and 41. By interchanging the mountings for the pinion 37 and the member comprising 35 and 36 the mechanism to which they transmit power will be driven in such a way as properly to coact with the spindles should they be rotated reversely by rotating shaft reversely to the direction in which it rotates as shown in the drawings; upon such interchange, the pinion 42 and the member comprising 40 and 41 in Fig. 10 will be shifted to occupy the vacant slots shown in that figure.

The power is transmitted to the shafts 31 from shafts 32 (and incidentally from said shafts 32 to shafts 32) as follows: At the end of the machine shown in Figs. 2 and 4 the shafts 32 carry pinions 43 with which mesh gears 44 adjustable in slots 45 concentric with the shafts 32- on which are fixed the pinions 46 which mesh with pinions 47 fixed to rotate with the pinions 44. Fach pinion 46 carries a sprocket wheel 48 around which and a sprocket wheel 49 carried by a pinion 50 meshing with apinion 51 on the shaft 31 extends the sprocket chain 52; to vary the speed of rotation of each shaft 31 relatively to shaft 32 a pinion 50 of diEerent size may be employed, 53 being a slot in which the mounting for the pinion is arranged allowing its proper engagement with the pinion 51 whatever its diameter.

54 are horizontal arms each secured to a rail 54 above a spindle 9 and in a slotl 55 in each arm is arranged to slide a vertically' f movable bracket 56 which normally stands in the position shown in Fig. `6 but which, when moved upwardly, is caused 'by a spring 57 to be caught by its shoulder 58 and hang suspended from the rail. By an adjustable slot and pin connection 59 the. lower end of this bracket is connected by a pitman 60 with one arm of a dog 61 pivoted in the spindle-rail, the other arm of said dog being adapted to shift the carrier 8 against the tension of its spring 11 (Figs. 6 and 7) 62 is a link connecting the end of lever 27 with the first-named arm of the dog. ln the bracket 56 is journaled a peripherally grooved thread-advancing wheel 63 which, in the normal position of the bracket, peripherally engages a friction wheel 64 on the shaft 32. ft will be apparent that when the bracket 56 is elevated out of its normal position it disestablishes contact between the wheels 54 and 63, causes the dog to shift the carrier 8 to disestablish contact between the spindles 9 and 10 and the belt d and disestablishes the connection between pinions 28 and 30, so that the advancing of the thread by the wheel 63, the rotation of the spindles and the traverse motion are all stopped simultaneously. Side by side with the friction wheel 64 is a ratchet 65 with which engages the lower end of a dog 66 when said dog is caused to move out of its normal position,z'. e., where its upper weighted end rests against a stop 67 on the bracket 56 in which the dog is pivoted. rl`he dog is moved out of its normal position by one of a group of fallers 68 each normally held in the position shown in Fig. 6 by the thread, which is passed around the guides 69 on the bracket 56 and also around the upper or longer arm of the faller. ff the thread breaks, the faller, being released, moves against the dog and throws it into the path of the ratchet whereby the bracket 56 is elevated and latches itself to the rail 55, stopping the diderent mechanisms controlled thereby, as described.

lin doubling, twisting and qui1ling, the threads are taken from supply bobbins 70 arranged on skewers in substantially radial relation to a horizontal bar 71 over which and a broad curved blade 72 laterally and rotatably adjustable on said bar the threads are passed, from whence they extend around the guides 69 andthe faller, then around the' peripherally grooved advancing wheel 63 `(preferably extending also through a guide 73 insuring their being retained on e the advancing wheel) and then through traveler 23 to the spindle 9. rlFhe thread is shown as thus described in broken lines, Fig. .f

3. yBy rotatably adjusting blade 72 on the bar 71 the tension may 'be varied, as will be obvious.

' ln quilling, without doubling or twisting,

a supply spool is placed on the spindle 10 f and the thread' is eXtended through the guide 74,' around guides 69, engaged with -a faller and passed around the advancing vto the traveler 23 at which the thread thread is taken from one ofthe spools 70 and supplied to the rotating spindle9 lthe same as in doubling, twisting and qullling. The wheel 63 being directly over the re- 'ceiving spindle 9 it is available to advaiibe the thread in any of the foregoing operations. By changing the ratio 'of the speeds of the rotary receiving spindles and the traverse mechanisms the pitch of the windings may be varied; and by changing the ratio of the speed of the spindles relatively to the extent (or frequency) of contact of friction wheels 19 and 33, the diameter of the wound package may be varied.

It will be observed on reference to the drawings that the nearest point relatively 1s guided is suiiciently away from as well as substantially alined with the spindle so that the thread balloons and thus creates a resistance to the advance of the thread which produces a nicely adjusted ornatural tension, suflicient to keep the thread under proper control at all times without tending to produce undue breakage. The hardness (compactness) of the wound package may be varied by varying the weight of the traveler. Having thus fully described my inven tion, what I claim as new and desire'to secure by Letters Patent is l. In combination, with Va suppbrting structure, a spindle driving belt, means for driving the belt, parallel spindles arranged on opposite sides of the belt,'and means for supporting and moving the spindles into and out of simultaneous contact with the belt including a carrier carrying both spindles and pivoted to move on an axis parallel with the spindles, substantially as described.
