The present invention relates to the setting and winding of tuft yarn and more particularly to an improved setting frame.

Setting frames as heretofor-e constructed and used have been of generally massive appearance and of complicated design with involved yarnmeasuring devices and tension mechanisms. Whereshort spools only were to be wound and factory space was o-f minor consideration these prior machines carried out to a certain degree the function which was intended. With the advent, however, of relatively long spools foruse with the modern looms a demand has existed for a setting machine of a more practical, economical and eilicient nature and this demand, until the machine of the present invention was devised, hasl remained unsatisfied. For example vin prior setting Vmachines in which attempt is made to wind yarn upon the spools the operator or setter must lean across the yarn stretching from the supply spools to the comb a-ndin doing this pushes the yarn at the side toward thel center so that not only does it become displaced but also damaged and tangled. Furthermore the high side frames of the machine, covered as they are with gears, springs, levers, and so forth completelyprevent the setter from -access to that portion of the yarn beyond the comb. u A Some of the objectsjof the present invention are to provide an improved machine for setting and winding yarn" upon spools for use in Axminster or other looms producing tufted fabrics; to provide aenovel setting frame wherein the operator can enter between portions of the machine to reachthe center part o f a spool without coming into contact with the set yarn;Y to provide armachine wherein a setting operation takes place yat one partof the machine and the winding operation at another portion o f the machine; to provide means for transferring a yarn spool from, a setting location to a winding location; to provide a machine consisting of spaced setting and winding units withmeans for shifting a spool from one unit to the other; toprovide a device for maintaining a substantially uniform tension upon a pluralityof yarn lengths during a'winding operation; to provide a yarn spool having parallelly arranged yarn receiving slits and a setting and vwinding-*means coacting with said spool, to provide means for winding a yarn spool more evenly than heretofore; to pro-v vide a measuring apparatusvwhereby it is possible to windV each spool with the same amount.V of yarn; and to provide other improvements as will hereinafterappear.

In the accompanying drawings Fig. 1 repl resents a side elevation of a setting and winding machine embodying one for-m of the present inventiomthe same being shown in operative relation `to the spool bank; Fig. 2 represents a plan of the same; Fig. 3 represents an enlarged section on line 3 3 of Fig. 2; 4 represents a fragmentary section on line 4- 4 be transferred to the winding unit and Fig. 6 represents a plan of the setting unit showing the tension roller in its inoperative posilon.

Referring to present invention consists of 'a frame 10V for a winding mechanism which forms, one unit of the apparatus and a frame 11 spaced therefrom to mount the setting mechanism which forms the other unit thereof.; As shown in` Fig. 1 the two units 10 and 11 are operatively located withrespect to the associated spool bank 12 and are spaced apart to provide a passage 13 which can be entered at either end by the operator.

For yrespectively separating and locating the yarn strands 111 as dra-wn from the spools 15,. a reed 16 bridges the space between the leg walls 17 and extends vertically upward therefrom andV parallel to the front end of 'the spool bank 12. Thus as each strand of of Fig. 2'; Fig. 5 represents a section similar v to Fig. 4 but showing the set spool ready to the drawings one form of the the aid of the ordinary clamp bar. One spool is set at a time and each is inserted between a pair of spaced cups 21 which are respectively pressed towards the spool ends by springs 22 reacting against end standards 23 rising from and fast to a movable carriage 24. This carriage 24 has side tongues 25 to respectively enter guide slots 26 in the wallsV 17f'wherebyV the kmounted Yspool18 takes a setfting position parallel to the stationary reed 16, but is capable of a movement towards and away from the reed 16 for a purpose to be presently described. A comb 27 is fixed to the carriage 24 so that in setting position it isk relatively close to the reed 16,V parallel thereto, and also between ther'eedl 16 and the spool 18k.` q

For winding the spool V18 after the setting operation is completed the winding frame l0 ournals two rollers 28 and 30 arranged side by side in parallel relationbut so spaced as to partially receive the spool 18 between them in order to frictionally drivethe spool 18 to wind the yarn thereon. The respective roller shafts 31 and-32 have gearsl 33 and 34 keyed thereon to be driven from a common gear 35 which is fast to a counter-shaft 36 carrying a sprocket wheel 37. A chain 38 trans- `mits motion tothe wheel 37 from asprocket wheel 40 upon a driven shaft 41. A motor 44 or any other suitable means furnishespower 'to the vdriving shaft 43. With the spool r18 seated upon the driving or winding rollers .28 and 30 it is held in frictional engagement therewithby a pressure roller resting upon the upper periphery-of the spool 18 and yieldingly holding it pressed against the winding rollers 28 and y30. This yielding pressure means consists in the present instance of two coiled springs 46 and 47 held `respectively under compression in the two cages 48 and v50 which are fastened to the frame l() and are vertically slottedy to receive the ends of the shaft upon which the pressure roller 45 is mounted. tThis slotted construction allows the roller. 45 to' rise verticallyV against the pressure of the springs 46 and 47 as the yarn Vbuilds upon the spool 18 and at the same time maintains the roller 45 in its proper operative position relative to the spool and the rollers 28 and 30. K For the purpose of transferring the car- AAriage 24 from the setting unit to the wind- `v`ing unit, the two units are interconnected by twospaced guide tracks 51 which are of substantially inverted L-shape in cross section in order to ride in a groove 52 in the bottom of the carriage 24. These tracks 51 are equally spaced from the center of the setting unit 11 and bridge the passage 13 to connect with A the winding unit 10.V Depending from the carriage' 24 and vcentrally disposed'of the `open side of the groove 52is a hanger 53 'which ournals a pinion 54 arranged to mesh with afixed rack 55j. This rack 55 is connectand another-set-up is to be made.

In order to maintain the proper tension lupon "the yarn strands during the winding and compensate for the Yvariable pull upon the spools as the latter are unwound, an arm 56 is pivoted to the outer side of each of the leg walls 17 and has a Aradial length to carry a tension roller 57 above and over the spool 18 which is in position for setting. The

'roller 57 is journalled between the two arms .56 and can be manually swung from inoper- .ative position as shown in Fig. 1, to operative position as shown in Fig. 5Uwhere it rests upon the yarn strands with just suflicient pressure to maintainthe desired tension ybut without interfering with or retarding the V free travel of the strands under 'winding pull.

. When the spool has been completely Vwound and another spooll is-to be woundwith thek Asame set-up the carriage does not have tobev f moved back to the setting position but re-,

mains adjacent to the vwinding'rolls and there l.

receives-an empty spool which is "the-next to be wound. The empty spool is placed in position between the `cups, 21 andthe strands Yof yarn are connected to it by inserting them respective-ly' in the spoolslits20.v This `operation anchors the row of yarn strands to the empty ,spooland a retainingbarG() is inter-locked with the strands of yarn between two spools and then the yarn isfcut relatively close to the spoolabout to be wound so that the wound spool can be removed with .its yarn ends held by the -retainingbar and i the empty spool isthen manually removed from the setting frame into windingv position` between the rollers'28 and 3,0 and the pressure roller 45. The slotted block 61 extendstransversely of the carriage, parallel to the reed 27, and serves to receive and hold the retainingbar with its teeth in a vertical position ready to receive the strands offyarn ,when-.required.

While only a single 'form is shown in which this invention may be embodied, it'isto be understood that the invention is not limited .Y l to any specic construction, but might ybe applied to various forms without departing from the spirit of the invention or the Vscope of the appended claims. Y.
