JOSEPH CARDIN AND EUGENE DEADY, 0F PROVIDENCE, RHODE ISLAND.

SKEIN-YARN-SETTING MACHINE.

Application filed February 24, 1915.

T 0 (ZZZ whom it may concern:

Be it known that we, JOSEPH CARDIN, a subject of the King of Great Britain, and EUGENE DEADY, a citizen of the United States, residing at Providence, in the county of Providence and-State of Rhode Island, have invented a new and useful Improvement in Skein-Yarn-Setting Machines, of which the following is a specification.

This invention relates to certain new and useful improvements in skein yarn setting machines, and the primary object of the invention is to provide improved means for stretching and setting the yarn.

A further object of the invention is to provide improved means for retaining the lower rolls in position; to provide means whereby the lower rolls may be easily and quickly removed and replaced, which latter means more specificallyis of the gravity actuated type: to provide improved means for tensioning the rolls and for compensating for contraction of the yarn; to provide means for rotating the rolls so as to cause'the yarn to travel through the setting fluid or liquid; and to otherwise generally simplify and improve a machine of the type indicated.

In the drawingsFigure 1 is a side elevation. Fig. 2 is an end elevation. Fig. 3 is a top plan view, showing the machine arranged in a vat, the latter illustrated in dotted lines. Fig. 4 is an enlarged detail sectional view on the line 44 of Fig. 3, and Fig. 5 is a similar view on the line 55 of Fig. 1.

The invention includes a frame comprising a base 1 having vertical corner standards 2 thereon, over which is slidably received a lower or reciprocal head 3 which is in opposition to an upper rigid head 4.

Arms 5 project up from the lower head and have blocks 6 bolted to their upper ends,

the blocks 6 having stirrups 7 pivoted to their upper ends, the stirrups engaging at the top of the ends of a spring yoke 8, the ends of the yoke being turned upwardly at 9 so as to prevent disengagement from the stirrups 7.

A threaded boss or sleeve 10 is secured to the center of each of the yokes 8, each of the latter having, an aperture which registers with the interiors of the sleeves, so that a threaded shaft 11 equipped with a handle 12 .may be threadedly engaged with. the interior of the sleeve.

The rigid upper head 4 which is prefer- Specification of Letters Patent.

ably bolted to the standards 2 in order to render same rigidly in connection with the standards, has a bearing 13 on each end through which the shaft 11 passes, the shaft being provided with a collar 14 which seats on top of the bearing 13 and with a collar 15 engaged below the bearing 13, so that upon rotation of the shaft vertical movement thereof is prevented.

The upper head is provided with a series of roll end seats 16 the number of which depends upon the number of rolls employed, which seats receive one of the ends of the rolls,.the other ends of the rolls 17 having squared extensions 18 received in squared or angular sockets 19 rigidly connected to stub shafts 20, the latter being journaled in spaced walls 21, 21 on the upper head 4.

l/Vorms 22 are secured on a shaft- 23 the latter being journaled in the head 4 and rotated by a drive pulley 24 or other appropriate means. The worms 22 mesh with worm gears 25 secured on the stub shafts 20, by means of which the latter with the upper rolls 17 are rotated.

The lower rolls 26 have cylindrical ends 27 engaged by the locking dogs 28, the latter being of substantially L-shape and pivoted at their upper ends at 29 to the lower head 3 and having their horizontal ends provided with upper beveled parts 30 and with downwardly facing socket parts or seats 31 which receive the top portions of the cylindrical ends 27 of the lower rolls 26 as evidenced in Fig. 5 of the drawings. The horizontal free ends of the dogs operate through slots 32 provided for their reception in the head 3, as shown in Fig. 5 of the drawings. Guides 33 may be employed and secured to blocks 6 to guide the up and down movements of the lower head 3.

In operation the top rolls are passed through the skeins of yarn as are also the bottom rolls, following which the rolls are placed in their respective top and bottom heads, the sockets 19 being left open to enable the rolls to be removed from and replaced therewithin as depicted in Fig. 4 of the drawings. In placing the bottom rolls in position, it will be evident from Fig. 5 of the drawings that the ends of the bottom rolls will ride down on the beveled faces 30, and will move the locking dogs outwardly until the roll ends disengage from the beveled faces 30, at which time the locking dogs. will, due to the action of gravity, return to their normal positions in the slots 32, as

shownin. Fig. 5, and will receive or engage the roll endsin their socketed parts or seats 31, the lower rolls being supported by the yarn which engages over the top rolls. The handles 12 are now turned so as to cause the bottom head 3 with the rolls thereof to move downward, and due to the spring nature of the yokes 8, the lower head will be placed under spring tension. The handles 12 are turned to effectthe desired tension on the yarn, whereupon the entire structure hereinabove described is placed in a vat V, and steam or hot water forced into the latter, and power applied to the pulley 24, which causes the yarn to move inthe vat and be thoroughly subjected to the action of the hot water or steam, thus properly setting the yarn, which latter may be'subjected to the action of the heated fluid until the desired setting of the yarn has been obtained. Should however, there be any contraction in the yarn, the spring yokes will give or respond sufiiciently to prevent breakage ofthe yarn. The springs thus perform aniinportant function since they resiliently tension the yarn and in event of contraction thereof give so as to prevent breakage of the yarn.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. In a yarn setting machine, a frame, an upper head rigid on the frame and a lower head reciprocable on the frame, rolls, connected: to each frame, a spring yoke connected to the lower frame, and means connected to the yoke and to the rigid head whereby to move the lower head toward or away from the upper head 2. In a yarnsetting machine, a frame, a rigid and a reciprocable head on the frame, and unitary means to hold the reciproc'able head in suspension and to enable the reciprocable head to be moved away from the rigid head and to allow the same to move toward the rigid h'eadupon contraction of the yarn.
