i 1E3 Claims- 1 (CL 57-48) This'inventionrelates to themanufacture of at a faster speed than the traveling movement so-called novelty yarn.

One object ofthe invention is creating the'novelty effect in the yarn'in the spinning frame on which the yarn is spun and simultaneously with the spinning operationj One common way' of making a novelty yarn is -to'twist together in a twister frame,'two or more-ends or strands which may be of different rolls. Ifthe strand is fed to the drafted roving to provide for of said roving while' the spinningtwist' is imparted thereto, then the strand'will be wrapped around the drafted roving as it is being twisted and the turns of the strand will have an irregular or random arrangement, thus giving the desired novelty effect.- H

This novelty effect-is thus produced on the spinning frame and during the spinning operaco'lors and/or of different material and/or both; tion so that the yarn which accumulates on the and one way of providing anovelty effect is to yarn carrier of the spinning frameis a novelty feed one of the ends or strands into the'twister yarn and requires no further manipulation or frame at a faster rate than the other end 1 or treatment to produce the novelty effect. This strand with the result that the strand which is p ep re n vel y-prod cing str nd m y b a' p n fed faster will be wrapped about the other strand yarn ora filament yarnor a strand of any other 7 in' an irregular or random manner, some of the suitable character. i turns of the faster-fed strand being relatively In order to give anunderstanding of the in close together" and other turns being Widely sep Vention we have illustrated in the drawings some arated.

This novelty-producing of which the r'oving lfto be drafted and spun' strand is preferably fed to the drafted roving is'conipb'sed. f a I T v at a speed different from that at which said In-the'illustrated embodiment of the invendrafted roving is being delivered from the front 7 "tion,this drafting apparatus comprises theupper and lower backrollsfi and 6, the upper and lower 2 front rolls I and 8, the intermediate carrier rolls 9 and cooperating tumbler rolls III. This is the type of drafting apparatus commonly known as the worsted type that is used for drafting relatively long fibres, but if the roving 4 is composed of relatively short fibres, then a drafting apparatus suitable for such shorter fibres would be used. many event the drafting apparatus is of some usual type which produces a drafted roving of substantially uniform size.

The twisting and Winding device 3 by which the spinning after it is delivered from 8, and by which the yarn is wound on the yarn carrier 24, may be ofany usualkind such as ring spinning device, cap spinning device, or a fiyer. Merely for illustrative purposes, we have shown herein a twisting and winding apparatus of the cap spinning type. v

40 indicates the ordinary fly board which is commonly used on spinning frames for guiding the yarn during the spinning and windingoperation. j V I v 1 I In order to produce a novelty yarn on the spinning frame, we provide said frame with means for feeding a prepared novelty-producing strand II, such as a spun yarn or a. filament yarn, to the drafted roving 4, which is of substantially uniform size, at a point between the 1" rent rolls I, 8 and the twisting and winding device 3 and while the spinning twist is being put into said drafted roving, said prepared strand or yarn being twisted with the drafted roving in such a way as to produce the desired noveltyeffect. This strand IIv which is shown asbeing taken from a spool I2 carried by the spinning frame, is fed positively to the drafted roving 4 by means of suitable feed rolls I3, I4 which are situated in front of the' front roll I in position to deliver the strand II directly to the drafted roving 4 between the front rolls and the fly board 46.

One or both of the feed rolls I3, I4 is positively driven and said rolls constitute means for positively feeding the novelty-producing strand II directly to the drafted roving 4. Said feed rolls are positively operated so as to feed'the noveltyproducing strand to the drafted roving 4 at a uniform speed different from that at'which the drafted roving is moving forward.

Since the'novelty' producing strand II is being delivered positively from the feed rolls I3, I4

directly to the drafted roving 4 at a uniform speed, thepo'rtion of said strand between the feed rolls and the drafted roving will be under a uniform tension. Said strand II, therefore, is delivered directly to the drafted roving 4 under a uniform tension.

This strand II may be made of any desirable material and may have any desirable color depending upon the novelty eflect which it is desired to produce, and as stated above, it may be spun yarn or a filament yarn or a strand of any other suitable character.

If the strand II is fed to the drafted roving at speed faster than that at which the drafted roving is delivered from the front rolls, then said strand I I will be wrapped more or less loosely around the twisted roving 4 and the turns of the-strand will have an irregular or random arrangement something as illustrated in Fig. 5, wherein 4 indicates the drafted roving of uniform size which has been twisted by the twisting and winding apparatus 3, and II indicates the strand which is wrapped about the twisted roving twist is put into the drafted roving the front rolls I and;

surface speed 4, thereby producing a novelty yarn 25. As stated above, the turns of the strand II will have an irregular or random arrangement, some of the turns being quite close together as indicated at I9 and other turns being widely separated as indicated at 23. If the strand II is of a different color from the strand 4, the novelty effect produced by the irregular or random arrangement of the turns of the colored strand II will be enhanced.

If the strand I I is being delivered from the .front rolls 1 and 8 at the same speed as the drafted roving 4 then the twisted roving 4 and the strand I I will be twisted together quite regu larly as illustrated in Fig. 4.

If the strand II is delivered to the drafted roving 4 at a slower speed than that at which the roving is delivered from the front rolls 7 and 8, then the tendency will be for the twisted roving to wrap itself around the strand II and a still different novelty efiect willbe produced.

In any event, the novelty effect of the yarn 25 is produced by the way in which the noveltyproducing strand II is twisted with the spun yarn that is formed by imparting the spinning twist to the drafted roving 4,and such novelty yarn will have much the same effect as would be produced by doubling or twisting together two spun yarns in a twister frame, but as the novelty effectis produced directly on the spinning frame. the necessity of any subsequent manipulation of the yarns after removal from the spinning frame in order to create the novelty effect is obviated.

The feed rolls I3 and I4 are positively driven and may be operated in any convenient way. As herein shown, the lower roll I 4 is a driven roll while the upper roll I3 is in the form of an idler which is rotated by its frictional contact with the driven roll I4.

In Fig. 3, we have illustrated a schematic layout for driving the various rolls of the drafting apparatus and also for driving the feed roll I4. In said Fig. 3, 2| indicates a shaft'on which the bottom front rolls 8 are mounted and which is driven from any suitable driving gear 22 at a uniform speed as usual in drafting apparatus.

This shaft is connected to the shaft 23 on which the back rolls 6 are mounted by any usual system of gearing 26 which includes a gear 32 V The feed roll I4 is a relatively long roll which is geared to and is driven from. the shaft 2!. For this purpose, said roll I4 has a gearing 2! rigid therewith which meshes with a gear 28 carried by a shaft 25, the latter having another gear 30 thereon which meshes with an intermediate gear 3I that in turn meshes with and is driven by the gear 32. A plurality of upper rolls I3 may be provided, one for each of the front rolls 8 and these rolls I3 are shown as provided at their ends with trunnions 44 which are received in bearing slots formed in upstanding arms 45 which are carried by a suitable supporting, bracket 46 that is attached to the frame.

The gears 21 and 28 are interchangeable for gears of different sizes so that by removing the gears and replacing them by other gears of different size, the surface speed of the feed rolls I3 and 14 may be varied with regard to the surface speed of the front rolls 7 and 8 and thereby means are provided for rotating the feed rolls II-2 and Meither faster or slower or at the same as that at which the front rolls I and 8 are rotated. Said feed rolls I3, I4 are thus positively driven at a controlled speed, and

the strand H will be delivered directly to the drafted roving 4 under uniform tension.

In Fig. 2, we have illustrated a different embodiment of the invention in which the novelty yarn is composed of three strands instead of the two strands illustrated in Fig. 1. In the device of Fig. 2, provision is made not only for feeding a spun yarn or other strand to the drafted roving to be twisted therewith, but also for feeding a third strand, either in the form of a spun yarn or a filament yarn, or in the form ofa drafted roving, to the front rolls immediately in the rear thereof, which third strand is fed through the front rolls with the drafted roving 4. This third strand, which is indicated at 33, is twisted with the drafted roving 4 while the two strands are traveling from the front rolls to the point where the strand ll isadded to produce the novelty effect, and from this point to the yarn carrier the three strands will be twisted together. If the strand II is being'fed by the feed rolls l3 and I4 faster than the combined drafted roving 4 and the other strand 33 is being delivered from the front rolls, then said strand I I will be wrapped around the other two strands and the turns of the strand II will have an irregular or random arrangement as indicated in Fig. 6, some of the turns of the strand ll being relatively close together as indicated at 34 and other turns being more or less widely separated as indicated at 35, thereby producing the novelty effect.

By making the necessary changes in the sizes of the gears 21 and 28, the speed with which the feed rolls l3 and I4 deliver the strand H may be changed so that it will be the same as, or even slower than the speed at which the two strands 4 and 33 are delivered from the front rolls 1 and 8 and thereby the novelty effect of the completed yarn will be varied.

Our invention, therefore, provides a novel spinning frame adapted to produce a novelty yarn by feeding at a controlled speed a'prepared noveltyproducing strand to a drafted roving of uniform size at a point where the spinning twist is being put into said drafting roving, and it also provides a novel method for thus making a novelty yarn.
