WEFT-CARRIER MAGAZINE.

Original application filed July 18, 1921, Serial No. 485,420. Divided and. this application filed April 28,

1924. Serial No. 709,410.

To all whom it may concern:

Be it known that I, EPPA I-I. RYoN, a citizen of the United States, residing at Pasadena, in the county of Los Angeles and State of California, have invented a new and useful eft-Carrier Magazine, of which the following is a specification.

This application is a division of Serial No. 485,420, filed July 18, 1921, and relates to certain improvements in weft carrier mega zines as applied to weft replenishing looms, having for its object the provision of a magazine of simplified construction and very reliable operation.

This application relates particularly to an improved weft carrier releasing device, which in its preferred form comprises a bobbin support yieldingly mounted on a pair of parallel links by which the support is guided outward and upward to successive parallel positions.

My invention also relates to certain arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

A preferred form of my invention is shown in the drawings in which- Fig. 1 is a side elevation of a magazine embodying my improvements, and

Fig. 2 is a partial rear elevation looking in the direction of the arrow 2 in Fig. 1.

Referring to the drawings, I have shown parts of a magazine comprising an end frame 10 connected to a second end frame (not shown) by cross rods 12, 12 and 13 (Fig. Vertically extending flanges 14 on the end frame form separate vertical passages or compartments in which stacks or rows of weft carriers may be assembled.

The lowermost weft carrier of each stack rests upon a support or slide similar to those shown in my prior Patent No. 1,005,821, issued October 10, 1911, and by which the weft carriers are relatively released upon indication of weft exhaustion. Vertically disposed guide rods 31 and 32 outside of the magazine end frame 10 prevent entanglement of the weft ends as the weft carriers are fed downward in the magazine.

My present invention relates particularly to improved devices for yieldingly supporting the tips of the bobbins or weft carriers. These devices comprise guide members or supports 33 each mounted on parallel links 34 and 35. The links 84 are pivoted at 36 on the frame 10 and the links 35 are loosely mounted on the cross rods 13. Coil springs 37 encircle the rods 13, one end of each spring being secured in the hub of a link 35 and the other being secured in a collar (not shown) on the rod 13 and by which tension of the spring may be adjusted. An adjust ing screw 39 in the link 34 acts as a stop for the weft carrier support by engagement with a shoulder 40 on the frame 10.

The two supports 33 are similarly constructed and are mounted to be moved apart as a weft carrier is forced downward by the ransferrer 41. Either of them may also be forced further back to the dotted line position shown in Fig. 1 if a weft carrier fails to be properly transferred and is caught by the shuttle when only partially inserted. The parallel links cause the guide plates 33 to maintain their original angular relation as they are separated.

In this way, a support 33 is moved quickly upward out of the path of movement of a misplaced weft carrier and easily clears the weft carrier without damage to the support or to the weft carrier.

Having thus described my invention, it will be evident that changes and modifications may be made in my invention within the spirit and scope thereof as set forth in the claims and I do not wish to be otherwise limited to the details herein disclosed but what I claim is 1. In a magazine, a support for the tip of a weft carrier, means to position said support and to guide said support outward and upward to successiveparallel positions and to prevent displacement of said support from parallelism, and means to yieldingly return said support to operative position.

2. In a magazine, a support for the tip of the weft carrier, a pair of parallel links on said support, and a spring to yieldingly hold said support in operative position.

In testimony whereof I have hereunto affixed my signature.

EPPA I-I. RYO N.
