DRAWING-FRAME AND ART OF DRAWING AND=DOUBL|NG SLIVERS.
277,606, dated May 15, 1883.
Application filed November 25, 1882. (No model.)
To all whom it may concern Be it known that I, J.E. PRES'I, ofFall River, county of Bristol, State of Massachusetts, have invented an Improvement in Drawing-Frames and in the Art of Drawing and Doubling Slivers,of which the following description, in connection with the accompanying drawings, isa specification, like letters on the drawings representing like parts.
In the manufacture of cotton as now prac-- ticed in cotton-factories the slivers taken from the carding machine are placed in cans, and two or more of the said slivers taken therefrom are drawn and united to form one sliver and again delivered into a can, and the doubled or combined and drawn slivers are again taken from these cans, combined with other-similar doubled and drawn slivers, and again drawn and delivered into cans. So, also, a machine has been devised to draw several slivers, which are then passed through trumpets and between other drawing rollers, and then are brought together intoa single trumpet, from which the single sliver, composed of several slivers previously drawn two or more times, is passed between condensing'rollers and delivered into a can. The first of these plans is objectionable, handlings required and ofthe liability ofthe slivers being broken when being taken from the cans. in the second plan referred to, the slivers, which are doubled, are simply drawn, not condensed; and in practice I have discovered that it is very difficult to make uniform strong yarn when the doubling operation is performed after drawing, but with- I out previously condensing, the slivers, for the uncondensed slivers have not suificientstrength to be fed through the machine without stretching them unevenly, which makes weak spots, causing frequent breakage and resulting in the production of yarn of unequal strength.
In my experiments I have found that the sliv- -ers may be successfully drawn and doubled in succession for any number oftimes, provided they are condensed after they are drawn and doubled and before they are again drawn and doubled; and my invention consists, essentially, in an organized -machine composed of two or more independent sets of drawing-rollers, trumpets, and condensing-rollers, the first set drawing, doubling, and condensing its slivers before delivering them to the second set to be again drawn and doubled.
The machine herein shown contains several sets of primary drawing-rollers, each adapted to draw two or more independent slivers, a trumpet for each set of primary di'awingrollers, and condensing-rollers to condense the drawn and doubledslivers issuingfrom between each set of primary drawing-rollers, and also other sets of secondary drawing-rollers to receive the drawn and condensed slivers from the condensing-rollers, which cooperate with the several sets of primary drawing -rollers first mentioned, and two sets of trumpets and sec ondary condensing rollers following the two sets ofsecondary drawing-rollers referred to,the combined slivers from the said secondary rollers passing into cans. By this method I am enabled to dispense with the usual canning operation between the first and second drawing and condensing operations referred to, and consequently to make stronger and more uniform yarn and save very considerable time, thus reducing the cost of manufacture of yarn, and at the same time my duplex drawing frame or head is cheaper to build than would be two independent frames such as required to do the same work in the old way, and my improved frame occupies much less space in the mill than the two frames and their additional sets ofcaus.
Figure l is a top or plan view, oartially broken out, ofa drawing frame or head embodying my invention; and on dotted line m, Fig. 1.
The frame-work A, ofsuitable shape to contain the working parts, has a main shaft, a, provided with usual fast and loose pulleys, or (L This shaft (1, as usual, carries the under roller, I), of the primary or main set of drawing rollers B, composed, as shown, of three pairs of rollers, b b, 0 c, d d, all geared to gether and driven one from the other in usual manner. The pinion on the shaft a, through the intermediate 0 turns the gear 0, fast on the shaft cflwhich carries and drives the lower rollers e of the primer set of condensin 7 7 b rollers e e, of usual construction. The two sliversff, shown as taken from the two cans f f and passed between the rollers of the first set, E, of three pairs of drawing-rollers, are doubled and led through the trumpets f and between the condensing-rollers e 6 by which they are formed into single slivers in the usual manner. These drawn and condensed slivers f issuing from between the primary condensing-rollers e e, instead of being fed directly into cans, as heretofore, and as in the second plan referred to, or as in United States Patent No. 128,618, are passed under carrying-rollers g-one for each pair of rollers 0 e -they co-operating with rollers g to turn the slivers, so that their course is thereafter parallel to the axes of the rollers b b. As herein shown, three independent drawn and condensed slivers are turned to the right and three to the left, as shown in Fig. 1, and the two sets of three drawn and condensed slivers, so turned aside from their original course, are passed between the secondary sets, 0 O, of drawing-rollers, located near each end of the frame, as shown, and from between them they issue as slivers 2 3 4:, and are doubled and passed through trumpets h, and thence between the secondary delivery and condensing rollers, h 7L2, into cans h. These drawing, donblin g, and condensing operations may be repeated any desired number of times before delivering the sliver into cans.
The arbors of the rollers g are provided with bevel-pinions g meshing with bevel-pinions g on a shaft, 9 actuated by the main shaft 0 through suitable intermediate gearing, 9 (shown in dotted lines, Fig. 2,) they thus conveying thesliver over the supporting tables or plates g to the two secondary sets of drawing-rollers O, which are alike, so that I need describe but one of them.
The shaft m of the lower or front roller of the three pairs of rollers which form the set of rollers O has upon it a pinion engaged by a gear, m on a shaft or stud having attached to it a bevel-gear, m driven by a bevel-gear, m, on the shaft 9 which actuates the rollers. 9 referred to and moves them and the slivers passingbetween them and the rollers gat the proper speed. The said shaft, by suitable gearing, N,
of usual construction, actuates the remaining pairs of rollers of the set of rollers O at the proper relative speed, and through the intermediate gears, 7, drives the condensing and delivering rollers h k by which the combined sliver is conveyed to the cans h.
I claim-- v 1. Thesetol'primarydrawing-rollers,atrumpet to receive the drawn slivers, and a pair of condensing-rollers to condense the drawn and doubled slivers, combined with a second set of drawing-rollers, between which the drawn and condensed slivers are placed to be again drawn, a trumpetin which thecondensed slivers subsequently drawn are doubled, and with a pair of secondary condensing rollers, to operate substantially as and for the purpose described.
C '2. The main set of drawing-rollers B, adapted to operate upon'several pairsof slivers and draw them, and the condensing-rollers e e, cooperating with them, means to operate the said drawing and condensing rollers, and the carrying mechanism to take the slivers from the said condensing-rollers and direct them to the sets of secondary drawing rollers, and meansto operate the carrying mechanism, combined with the sets of secondary drawing-rollers C G, and cooperating, condensing, and deliveringrollers h 71. and means to operate the secondary drawing-rollers and condensing-rollers h h substantially as and for the purpose described.
3. The herein-described improvementin the art of treating slivers for the production of yarn, which consists in primarily drawing, doubling, and condensing the same, and then in a continuous operation drawing and doubling the said drawn and condensed slivers and condensing them a second time before delivering them into cans, substantially as described.
In testimony whereofl have signed my name to this specification in the presence of two subscribing witnesses.
JOHN PREST.
