Application November 1'7, 1932 Serial No. 642,998

12 Claims. (o1. 19-420) This invention relates to a spinning apparatus and is a continuation in part of my co-pending application Serial No. 527,498, filed April 3, 1931, it has for one of its objects the provision of a 5 construction for long draft spinning in a single unit.

Another object of the invention is to eliminate the handling of the work between different processes in providing a yarn suitable for weaving, and other purposes.

A further object of the invention is the provision of a construction which will act upon a large sliver and control the selvages of the sliver in its passage thru different operations for reducing it to the size of yarn desired.

A still further object of the inventionis the provision of a more even yarn by spinning the same from the sliver where its size and weight per unit of length are substantially even.

Another object of the invention is the provision of a construction which may be controlled for each yarn end so that but one end in the spinning operation will be stopped should the yarn break, without the necessity of stopping other companion units for operating other slivers of yarns.

ll. still further object of the invention is the provision of a construction in which one of a plurality of hip rolls which engage the strand as it passes thru the apparatus will traverse one with reference to the other as they revolve that the wear may be distributed over the surface of the rolls rather than occur in one particular part c thereof.

i ith these and other objects in view, invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

Cotton sliver from the cardis usually doubled or several ends placed together thru a drawing frame, then a slubbing process and two or three P intermediate roving processes before spinning. A-twist is placed in the roving in order that it may he pulled from one place to another. and in order to eliminate several processes and spin the yarn directly from doubling where is more even, place a false twist in the sliver between each pair of drawing rolls to control the edges of the sliver and p "event the fibers at the edges thereof from fraying; and in order that the yarn may not be too tightly falsely twisted hetween the receiving and delivery rolls by which drawing will be retarded or prevented, I may place a false twist in the yarn in one direction between the first two pairs of drawing rolls and in the opposite direction between the next pair of drawing rolls and so forth thru the machine, whereby I may take the sliver di rectly fromv the doubling operation and spin the same with a long draft, thereby eliminating the sluh'oing and the intermediate roving pro- Q cesses and from which I may finally obtain an extremely long draft of yarn without fraying of the edges and a yarn of improved quality by reason of the fact that 1 spin the yarn directly from the doubling process at which point it is more even in weight and size than at any other step in the operation; and the following is a detailed description of the present embodiment of this invention illustrating the preferred means by which. these advantageous results he accomplishedz- With reference to the drawings, 10 designates the frame worlr of my construction, which consists of a plurality of decks which i designate as ll, l2, l3, l4, l5 and 16, which are supported. by suitable standards 17, maintaining them in the desired spaced relation which may be ad justable if desired by some suitable means.

Upon each of these decks, except the upper one 11, there is mounted a slidable plate which I will designate 18, 19, 20, 21, 22 and 23. The upper plate 18 has a central opening and is provided with

bearings

24 and 25 fixed thereon to rotatably support a fluted roll 26 therein, which roll is driven by means of a worm 27 and worm gear 28, from a suitable source of power supported by the frame work of the machine. A companion roll with an axis parallel to the axis of the roll 26 is yieldingly pressed towards the roll 26 to provide a nip on the yarn in a well known manner.

The

plates

19, 20, 21 and 22 are formed differently than the plate 18 and are illustrated in a plan view, shown in Fig. 3, and in section in Fig. 4. In each of these plates there is a central opening 29 with inwardly-extending gear teeth 30 provided around the edge thereof. The plate is provided with a finished surface 31 providing one part of the ball race and supporting balls 32 which in turn support a rotary member 33, which is shown in plan view in Fig. 5 and in section in Fig. 6. This rotary member is of dish shape and is provided with teeth 34 in a plane above the plate to mesh with a driving gear. The drive for each rotary member differs in that each is rotated in the opposite direction from the next member. One form is shown in Fig. 2, there showing a driving gear 35 which in turn is driven by a train of

gears

36, 37 and 38 connected to the drive shaft 39.

This rotary member carries a shaft 40 upon which a pinion gear 41 is mounted, which pinion is positioned to engage with the internally extending teeth 30 of the plate so as the rotary member turns about its own axis the shaft 40 will be rotated.

Upon this shaft 40 a worm gear 42 is provided which drives the worm 43 which is fixed on the worm shaft 44 upon which roll 45 is mounted, this shaft being suitably supported in bearings 46 and 47 fixed upon the rotary member 33. The

pitch of the teeth on the worm 43 and gear 42 will vary to cause the desired direction of rotation of travel. The companion nip roll 48 is suitably supported in a carriage 49 which may be slid over the surface of the rotary member supported by a boss 50, shown best in Fig. 6, and which carriage is forced towards the drive roll 45 by means of helical springs 51 abutting at one end 52 in the rotary member and encircling a pin 53 rockably supported in the carriage 49, whereby they may cause pressure to be applied to the roll in different positions of its axial movement wtih respect to the roll 45.

This carriage is slidable along the rotatable member and beneath a plate 54 which is held by bolts 55 firmly against an abutment 56 so that the carriage is guided in its travel between this plate and the slide surface 50 on the rotatable member.

In order that oscillating movement may be imparted to the carriage 49 and its roll 48, I have provided a worm 57 on the end of the roll shaft 44 with which there meshes a worm gear 58 fixed to a shaft 59 and rotatably supported in the rotary member 33. Below the gear 58, there is a spur gear 60 which meshes with an intermediate gear 61 fixed to a shaft 62 upon which there is also mounted a spur gear 63, which gears with gear 64 fixed upon another shaft 65 upon which there is provided a heart-shaped cam 66. A lever 67 pivoted upon the shaft 59 has a bifurcated end 68 to engage the heart-shaped cam for oscillating about the pivot or shaft 59 in response to movement of the cam.

A link 69 connects the free end of the lever 6'1 with the carriage so that as the cam operates the roll 48 will be oscillated axially back and forth across the roll 45 so that its leather covered surface will not become worn by travel of the strands between it and the metal fiuted roll 45 in any one place. A finger piece 70 is provided upon the carriage in order that the roll may be manually separated for taking out roll or other purposes.

Each of the

plates

19, 20, 21 and 22 is slidable into place on its deck and each is similarly equipped and they are arranged so that their pairs of rolls are at substantially right angles one to the other. The revolving of the rolls' about a center between them is had in opposite directions by adjacent decks so that they impart a false twist in the yarn. In Fig. 11, I have illustrated diagrammtically the rotary members A, B, C and D, comparable to the members 33 on the plates, 19, 20, 21 and 22 which are driven from a drive shaft 39. The upper rotary member A is shown as driven from the gear 72 thru an inter mediate gear 73. The next rotary member B is shown as driven from gear 74 thru two intermediate gears 75 and '76, in order that a reverse rotation may be imparted thereto. The next rotary member C is rotated from gear '77 thru a single intermediate member '78, in order that it may have the same rotation as rotary member A, while rotary member D is driven directly from gear 79 on the drive shaft that it may have the same direction of rotation as the rotary member B. The worm and

gear

42 and 43 will on members A and C have an opposite pitch from the similar worm and gear on members B and D. It will also be understood that the nip rolls are so geared as to rotate progressively faster that a draft may be had between them and the fibers pulled out to provide a yarn of the desired size.

The lower draft rolls on the plate 23 are similar in many respects to the mounting of the draft roll on the plate 18.

Bearings

80 and 81 are provided in which the driven roll 82 is mounted which is driven from the drive shaft '71 thru suitable mitre gears 83 and 84. A companion roll back of this drive roll is suitably supported and given the usual traverse motion which need not here be described.

Each of the plates upon which the rotary members and rolls are mounted may be slid into or out of the decks by a simple withdrawing operation which may be had by reason of the handle 85 mounted upon each of these plates. Each plate is held in position with its gears, the teeth of their rotary members 33 being in proper intermeshing relation by reason of the pin shown at 86 in Fig. 9, which is operated by a rotary shaft 87 having a handle 88.

By this construction a long draftmay be provided in a single unit, the sliver being taken from the large doubling strand and reduced to the yarn size desired thru successive operations and without imparting any permanent twist thereto.

By providing a false twist in the yarn between the upper and lower nips, the edges are turned inwardly and a more even draft is provided and the fray with consequent loss of fibers is reduced to a minimum and by this false twist the fibers are maintained in their desired compact relation and sufficient strength is given to the thread as it passes thru the different operations. Also by revolving the rotary members and the nip rolls in opposite direction a lower speed may be used for the revolving of the rolls in order that a false twist may be provided.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.
