SPINNIN G APPARATUS.

Application file d May 11, 1925, Serial No. 29,578, and in Germany October 8, 1924.

equipped with correspondingly simple appliances which are essentially distinguished in their construction and action from those used in spinning machinery for the manufacture of yarn in the factories, but, not- @withstanding their simplicity they completely fulfil the desired purpose and yield a strong fibre of good quality, whether it be as a single thread or as a twisted thread. The apparatus is intended to co-operate with a small carding engine in which the material to be spun, which may be flax, cotton, wool or the like, is first worked up to a fleece. The fleece thus obtained is refined'or attenuated by repeatedly passing through the carder before it passes to the actual spinning apparatus.

The invention is illustrated by way of example in .the accompanying drawings Where- 1n-- Figure l is a-plan of the apparatus;

Figure. 2 is a side elevation thereof;

, Figure 3 is a vertical longitudinal section on the line III-11]: of Fig. 1 on' a larger scale;

Figure 4a longitudinal section through a detail, likewise on a larger scale;

Figure 5 a pers ective view of a detail of the device illustrated in Figure 4 on a still larger scale and Figure 6 a side elevation of a detail also on a larger scale.

The invention consists essentially in a web divider, a draft device and any desired spinning apparatus. The web divider consists of a series of individual belts,1' and 2; 3 and 4; and also l 'and 2 3 and'4 which work together in fours. The belts l and 2 run from a roller 5, over a top roller 6, under a bottom roller 7, through tov a guide roller 8 and over a driving roller 9 arranged above the latter with a space between, and so back to the roller 5. These belts represent the top belts.

The

bottom belts

1 and 2 run from a roller 10 arran ed below the roller 5, always remaining substantially underneath the

belts

1 and 2, and likewise run between the rollers 6' and 7 through to a .roller 11. located in front of the roller 8 and from there back to the roller 10. The next pair of bolts, namely 3 and 4 or 3 and 4 as the case ma be, run in a similar manner,'but with the ifl'erence that these'four belts tra e r m he rol er 5 or 10 first'underneath a bottom roller 12 and over a top roller 13, as a result of which they are first shifted out of the plane of the

belts

1,2, 1 and 2 and are then guided back again into the said plane.

The next belts again run like the

belts

1, 2, 1 and so forth.

As a result of this arrangement the web that enters between the top and bott'om beltsas a coherent mass is first divided up into separate strips of web.

In certain of the rollers, for example the

rollers

5, 10, 6, 12, 8 and 11, guiding grooves are provided which brin about in a s ecial manner the collecting of the strips of necessary for the formation of a roving. Each guiding groove 14 in the roller 5 takes web up, for example, the belts 2 and 3, a further groove 15 takes up the belts 4 and 1 and so forth, in such a manner that between the grooves, guiding beads 16 are left standing which keep the

bolts

1 and 2, 3 and 4 at a distance from one another. applies to the

belts

1, 2*, 3 and so forth which are likewise kept at the right distance from one another on the roller 10. By this distance the breadth of the strip of web is determined when the web is separated. On the

roller

8 or 11, on the contrary, the

belts

1 and 2 and also the belts 3 and 4 are united in a common groove 17, 18 and so forth, in each case. By this means the result 'is obtained that the original wide strip of web is narrowed during its passage through the web divider and guided together in order to be presented in this condition to a rubbing leather 19 and rubbing roller20. The rubbing leather is in this case, preferably obliquely adjusted and designed'to take elf the The'same remark web from the bottom belt, for which purpose it bears upon the latter. The rubbing roller 20 accordingly bears upon the to belt and takes off the strip of web from the attera I It is essential that the

belts

1, 2 or 3, 4 and so forth, on the other way between the roller 8 and 9, leave a small gap just 'sufiicient to prevent the strip of ,webfrom being nipped movement no running together of the adja-.

c nt s p of eb c ta p e. i

The draft apparatus consists of a slide block; 21 which can execute a reciprocatlng movement in guide bars 22. This slide block is preferably inclined somewhat obliquely upwards. In the slide block are journalled sleeves 23 with a clamping device 24"and are driven from a roller 25 by means of bands. Theslide block consists of a stationary bar 27, in lateral guide blocks 26 1 and two

movable rails

28 and 29 kept apart by means of distance pieces. The

rails

28 and 29 can slide in the guide blocks for a purpose which will be hereinafter more fully set forth. The fixed rail 27 and the one movable rail 28 form'the support for the sleeves 23. The sleeves comprise at the end, a transverse groove 30 extending to the base of the longitudinal bore with a rather wide cavity '31. .In the sleeve is'displaceably supported a resilient clamping piece 24 which reaches,

by means of an arm 32, into the cavity 31 of the groove 30, and is rocked or shifted by means of an annular member 24 or the like when the

movable rails

28 and 29 are displaced, between which this annular memher is arranged. By the arm 32 the rubber thread is nipped in the cavity 31 as indicated in Figure 4. The delivery aperture 33 for the thread F is preferably displaced somewhat to one side in order to improve the nipping action. i V

The slide block is moved by means of an eccentric 34 through a lever 35 with a guide rod 36 from any desired driving position so that it arrives uniformly, but somewhat more quicl rly than roving, travels upwards and returns quickly, for example, under the action of its own weight, as well as a returning" spring 37, to its initial position. a

he driving of the sleeves or of the roller 25 is effected by means of a band drive passing over

guide rollers

38, 39 and 40 in such a manner that the roller'25 and with it\the sleeves 23 rotate as the slide block rises, but stand still or go more slowly during the return of the slide block. By'the sleeves so muchtwist is given to the clamped rubbed thread durin the ascent of the slide block that a draft is possible. In the upper position of the slide block the clamping device is opened by shifting the.

movable rails

28 and 29 by means of rocking arms 41, and by raising the arm 32, and the thread is released so that the sleeves can return above the thread during" the downward movement of the slide bloc The controlling of the clamping device is efiected by means of two

stops

42 and 43 which act upon an attachment 44 or a pawl 45 and thus impart a rotation to a shaft 46 carr in the rocking arms 41.

T e re is supplled over dofi'ers or stripper rollers to any desired spinning apparatus, for example, to a ring spinning frame with spindles 47, ring rail 48, traveller 49 and so forth. The ring rail is guided up and down in a known manner during the'operation of the spinning apparatus. The twist arising ate a result of the rotation of the sleeves is released again during the return of the slide block and during its ascent so that an untwisted fibre passes the dofiers and this fibre first receives the correct twist from the spinning apparatus.

By disengaging the web divider and the draft device the apparatus may also be employed for twisting or doubling, the fibres to be twisted being passed directly into the doifers.
