Application filed April 11, 1927. serial No. 1853,1272.

This invention relates to creels orjacks, the entire machineinust be stopped and the 55 and has for an object toprovide an improved construction wherein a yielding ac tion is provided so that undesirable strains on the yarn will be eliminated.

Another object of the invention is to provide a creel or jack wherein a pivotally mounted structure is presented, d'esignedto yieldafter a given pull.

A still further object, more specifically, is to provide a pivotally mounted creel or jack with adjustable resilient means normally holding the jack in a given position. and permitting a limited pivotal or swinging movement of the creel. In the accompanyingdrawings- Figure 1 is a front view of a creel disclosing an embodiment of the invention, certain parts being broken away in order that the creel may be shown on an enlarged scale.

Figure 2 is a sectional view through Figurel on line 2- 2.

Figure 3 is a view similar to the lower part of Figure 2 but showing the parts on Figure 1 is a detail fragmentary elevation of the lever, guide and associated parts shown in Figure 3 and embodying certain features of the invention.

Figure is a sectional view through me 3 on line 55. I

Referring-to the accompanying drawings by numerals, 1 indicates broadly the creel or jack and .2 the pivotal mechanism for permit-ting the creel 1 to swing within certain limits. The creel 1 is provided with the usual frznue 3 having the usual pins 4 for receiving the spools. A roller 5 is arranged at the top of frame 3, said roller guiding the yarn as it passes between the various pins -At the bottom of the creel a number of supporting rollers 7 are provided. The parts'from' 3 to 7 inclusi-ve,;-are old and well Figknown-and, therefore, will need no addi-- near the front end 12.

break repaired In tl1e'.present invention,

the creel has beenprovided with means for the creel toward the loom after a certain ten- SiOIl has been brought to bear on the yarn and in thisway the tension is relieved while the parts are adjusting themselves to the weaving operation. I

In order to bring about this result, the wheels 7 are left in place on the side of the frame 3 which faces the loom. The wheels on the opposite side are removed and auxiliary wheels 8 are provided which ordinarily act the same as the wheels 7,1 1'amely, to ass'lst iii supporting the creel so that it may be wheeled from place to place. Preferably there is one wheel 8 near each end of the creel, though others could be providedand other mechanism 2 could be provided and associated with the respective wheels 8; A As the'structure 2 and the wheels 8-are all identical, the description of one will apply to all, whether there is one, two or more used. As indicated particularly in Figures 3 and 5, the wheel 8 is journaled on a rounded extension 9 of the bar 10. This bar is bolted or otherwise secured to the frame '3 by a suitable bolt 11 extending through the bar The end of bar .10 nearest the wheel 8, loosely extends through a forkedmember 13 which is secured tothe frame 3 by screws or otherwise, said forked V ine'niber acting as a guide for the bar 10.

A lever 14' is provided, bent at 15 so as to provide an extension 16. bolt 17 loosely extends through bar 10' and through lever-'14 at the bend 15, a washer or other spacing member 18 being placed. between bar 10 and lever 14. As the opening through which the bolt 17 passes is larger than the bolt, the connection is sufficiently loose to allow the lever 14- to swing pivotally toan appreciableeXtent. The extension 16 projects through the opening 19 in the forked member 13 and bears against the bottom beam 20 of the frame 3. A retractile spring 21 has one end secured to the bar 10 and the other end connected to a bolt 22 which extends through a suitable opening in lever 14 and which accommodates the wing nut 23. By adjusting the wing nut 23, the effective action of spring 21. may be varied.

As illustrated in the drawing, the spring frame swings from the top toward the left in Figure 2, it will force the extension 16 downwardly and, consequently, will pull on the end of spring 21 which will resist more or less this pulling action. In case there is a long heavy pull, the frame 3 will swing until the extension 16 is resting on the bar 10. This will be the limit of the swinging action but usually the frame does not swing to this extent. After the partshave begun to operate, the tension will automatically decrease as the spools on the pins 1a have begun to revolve and the other parts begun to move. WVhen the inertia of these parts has been thus overcome, all parts will operate in a smooth and efficient manner and the frame 3 will gradually move back into substantially the position shown in Figures 2 and 3. In case there should be a breakage of any'of the yarn at any time, and the machine stopped, the same action will take place, namely, the creel will yield as the machine is again started.

That we claim is:

1. A creel including a frame and supporting wheels along one side, a plurality of bars connected to said side and extending to the opposite side, a supporting wheel mounted on the free end of each of said bars, a pivotally mounted lever mounted on each of said bars with one end engaging the lower edge of the frame for supportingthe same, and a spring acting on the opposite end of the lever for resiliently holding the lever in a given position.

2. A creel or jack including a frame having supporting members on one side, supporting wheels on the opposite side, a swinging bar connected to each of said wheels and to the frame whereby the frame on the side of the wheels may move up and down in a swinging movement, and resilient means for supporting the frame adjacent the wheels and means for resiliently resisting the downward movement of the frame at this point.

3.- A creel including a frame and a plurality of supporting means, the supporting meanson one side of the frame including a side and extending to the other side, a traction member for supporting the end of said one end will extend beneath said frame above said traction member for supporting-that side of the frame, and a spring memberfor resiliently holding the said opposite side of the frame in a given position and for al-" lowing thatzside of the frame'to move downwardly as the top of the frame ismoved substantially horizontally whereby a swing ing movement will be given the frame.

1. In a creel, a frame, a plurallty'of supports, the supports including wheels on one side, a bar acting as an axle for said wheels,

said bar at the opposite end being connected with said frame, means carried by the frame straddling said bar, a lever pivotally mounted on said bar with one end extending through said straddling means, said end acting as an auxiliary support for that side of the frame, and an adjusted spring for normally holding said lever in a given position.

5. In a creel, a frame, a plurality of' bars connected at one end to one side of the frame and extending to the opposite side across the bottom of the creel, atraction member connected to the free end of each of saidbars, a forked member secured to said frame and loosely straddling each of said bars, a substantially V-shaped lever for each of said bars pivotally mounted on therespective bars at the apex of the lever, one end of the lever engaging the edge of the frame carrying the forked member for supporting a frame at that point, and a spring connected to said bar and to the free end of said lever for resiliently holding the lever in a given position. 7

6. A creel having rearward, underneath and forward sides and means to hold a number of freely rotative wound packages and' guiding means over which the threads from said packages are to extend whenthey are siimiltancously drawn forward with respect to the creel, said creel being forwardly and rearwardly tilt-able and having rearward and forward supporting m ains on the rearward one of which the creel is thus .tiltable and the forward'one of which is arranged at the underneath side of the creol and yieldingly opposes the forward tilting of the creel.
