Application March 24', 1941, Serial No. 385,023

5 Claims.

My invention relates to improvements in yarn reels or swifts and has as one of the principal objects thereof the provision of a swift so constructed and arranged whereby tension may be applied to the skein of yarn contained on the reel in order to maintain the skein in a taut condition during its removal and thus preclude tangling of the runs during unwinding.

Another object of my invention is to provide a device of the character described so constructed and arranged whereby the same may be easily folded when not in use to form a compact assembly thereby enabling the device to be stored or transported in a relatively small space.

An important object of my invention is to provide a device of the character described which I is simple in construction, durable in use, eflicient in operation and economical in manufacture.

With the above and other objects in view, as will hereinafter appear, the invention consists in the combination, and arramement of parts hereinafter set forth and illustrated in the accompanying drawings, from which the several features of the invention and the advantages attained thereby will be readily understood by those skilled in the art.

Referring to the drawings wherein like reference characters designate like parts throughout the several views:

Figure 1 is a front elevation of my invention.

Figure 2 is a side elevation thereof.

Figure 3 is a sectional view taken on the line 3--3 of Figure 2.

Figure 4 is a view similar to Figure lustrating the device in folded condition a compact assembly.

Figure 5 is a perspective view of one of the fingers.

Figure 6 is a perspective View of the finger latching member.

Figure '7 is a detail front elevation lllustratmg the fingers in latched and retracted positions.

As illustrated in the drawings, I employ an elongated substantially vertically disposed standard 5 having its lower end provided with a clamp 6 for securing said standard to a support I, for instance, a table top or the like. The upper end of the standard 5 has attached thereto one end of a substantially horizontally extending shaft 8 on which is mounted a reel or sw1ft 9. The swift comprises a plurality of radially. extending spaced arms In including a mam arm I l and a ternary of axuiliary arms 12. The ma n arm H is of a greater length than the auxiliary arms to provide at one end a hub section 13 3 but ilto form rotatably journaled on the shaft 8. The inner ends of the auxiliary arms abut the sides and. end of the hub section 13 and thus dispose one pair of the auxiliary arms at right angles to the main arm and the other or interjacent auxiliary arm in' lengthwise aligned relation with said main arm. a

The inner ends of the foregoing described pair of the auxiliary arms are connected to the interjacent auxiliary arm, and one of the inner ends of said pair of auxiliary arms is connected to one side of said main arm, adjacent its hub section, by means of hinges M, while the other of said pair of auxiliary arms is connected to the opposite side of main arm by means of a hook and eye i6 and l'l respectively as clearly illustrated in Figures 1 and 3 of the drawings. Obviously, by disengaging the hook from the eye, the auxiliary arms may be folded together, one adjacent the other, and disposed on one side of the main arm to form a compact assembly capable of being transported and stored within a relatively small space.

Each arm I0 is provided on its front and rear faces'with pairs of inner and outer guides l8 and 19 respectively in which are slidably mounted the spaced pair of inner end sections 20 of a wire finger 2|, the outer end section 22 of said finger being of a substantially U-shaped configuration as at 23 and which coacts with the end sections 20 of the other fingers to receive therein the runs 24 of a skein of yarn 25.

An inner end section of each finger, overlying the front face of the respective arm and inwardly of its inner guide i8, is formed with an angularly disposed portion 26 terminating in a hook 21 to which is secured the inner end of a resilient member 28, the outer end of said member 28 being secured to the arm adjacent its outer end and serving to urge the finger outwardly with respect to the hub section.

Rotatably mounted on the shaft, adjacent the front face of the hub section, is a finger latching member or star-wheel 29 having a hub portion 39 provided with a quarternary of radially extending substantially cruciform arms or blades 3| normally disposed over the front faces of the arms I0 respectively and having their sides converging towards their outer ends. One side of each blade 31 constitutes a cam face 32 formed, adjacent the hub portion 30, with a notch 33 for receiving and maintaining therein the portion 26 of the respective finger against the urgency of its resilient member '28.

The opposite side of one of the blades 31 is provided with a laterally disposed finger-piece 34 for effecting sufficient rotation of the starwheel in a direction to release the portion 26 from within the notches 33. The opposite side ,of another of said blades 3| is provided with an angularly extending section 35 disposed adjacent a side face of the adjacent arm and is connected thereto by means of a spring 36, the latter serving to urge rotation of the star-wheel in an opposite direction to maintain the portions 26 seated within the notches 33. V

In use, the parts being in the positions illustrated in full lines in Figures 1, 2, and 3 of the drawings, the fingers are actuated inwardly whereupon the portions 26 engage the cam faces 32 of the blades and rotate the star-wheel a sufiicient distance to effect seating of the portions 26 within the notches 33. When the fingers are thus maintained in retracted positions by the star-wheel as illustrated in Figure 7, yarn is wound through the U-shaped outer ends of the fingers by rotating the reel about the shaft. When it is desired to remove the yarn from the reel and to preclude tangling of the same during the removing or unreeling operation, the starwheel is rotated to effect release of the fingers whereby they are urged into projected positions by the resilient members 28 thereby maintaining the skein in a taut condition while the skein is being removed fromthe reel during rotation of the it latter.

Without further elaboration the foregoing will I so fully explain the invention thato-thers may, by applyingcurrent knowledge, readily adapt the samefor use under various conditions of service.

Moreover, it is not indispensable that all the features of the invention be used conjointly since they may be employed advantageously in various combinations and sub-combinations.

It is obvious that the invention is not confined to the herein described use therefor as it may be utilized for any purpose to which it is adaptable. It is therefore to be understood that the invention is not limited to the specific construction as illustrated and described as the same is .only illustrative of the principles of operation,

which are capable of extended application in various forms, and that the invention comprehends all construction withinjthe scope of the claims. r
