THEFT-CARRIER MAGAZINE.

Application filed November 22, 1922.

T all whom it may concern:

Be it known that I, OsoAR TV. RICHARD- SON, a citizen of the United States, residing at orcester, in the county of lVorcester and State of Massachusetts, have invented a new and useful VVeft-Carrier Magazine, of which the following is a specification.

This invention relates to a weft carrier magazine and particularly to improved devices for holding the weft carriers in the magazine from relative angular movement. In looms using a plurality of kinds or colors of weft, certain weft carriers may be used very infrequently and may thus remain in the magazine for long periods of time. The vibration of the loom during a considerable period frequently causes relative angular movement of the weft carriers which entangles the weft ends and causes frequent breakage of weft upon transfer.

It is the general object of my invention to provide an improved and simplified construction by which such angularmovement of the weft carriers and consequent entanglement of the weft ends may be prevented. To this end, I provide means for yieldingly gripping the weft carriers at the sides of the butts, together with means for releasing the pressure on the weft carriers upon indication of transfer.

Further details of my invention will be hereinafter described and more particularly set forth in the appended claims.

A preferred form of my invention is shown in the drawings in which- Fig. 1 is a partial side elevation of a weft carrier magazine embodying my improve ments;

Fig. 2 is a sectional side elevation of the magazine, looking in the opposite direction from Fig. 1; and

Fig. 3 is a sectional elevation, taken along the line 33 in Fig. 2.

Referring to the drawings, I have shown a weft carrier magazine having an end frame 10 supported by a bracket 11 secured to the loom frame 12. The frame 10 is provided with vertical guide ways or compartments 18 in which the butts of the weft carriers are guided. A similar end frame (not shown) is provided for supporting the tips of the weft carriers, the frames being fixed in spaced relation by a plurality of cross rods or tie bars 14 (Fig. 2). The

lowermost Weft carrier B in each guide way 13 normally rests against the edge of a cradle 15 at the end of the guide way, as indicated at the right in Fig. 2.

Each guide way 13 is preferably provided with a fixed wall or rib 16 at one side thereof and may have a partial fixed wall 17 on the opposite side at the extreme lower end of the guide way. Throughout the greater portion of the length of the guide way, however, the second side wall is formed by a strip or plate 18 of spring steel or other resilient material, the lower end of which is preferably secured in a recess in the upper end of the side wall portion 17, the parts being secured together by a screw 19 or in any other convenient manner.

The plate or spring 18 is preferably oflset inwardly above its attachment to the part 17 and at its upper end is curved outwardly to engage a guide or rest 20. An oifset cam plate 21 (Fig. 3) is also secured to the outside of the spring 18 intermediate its ends for a purpose to be described.

Under normal conditions, the spring 18 presses inward against the butts of the bobbins B, forcing the butts against the fixed side wall 16 and gripping them with suflicient force to prevent relative angular movement thereof. o

Slide bars 22 are mounted on the outer face of the magazine end frame 10, said bars being normally in the lowered position shown at the left in Fig. 1., but being raised to the position shown at the right in Fig. 1

upon indication of transfer. The mechanism by which this movement is effected and controlled forms no part of my present invention and for a more complete description thereof, reference is made to the prior patents to E. H. Ryon, No. 1,022,108 and No. 1,080,748.

' As a slide bar 22 is raised, the corresponding cradle 15 is rocked from the position shown at the right in Fig. 2 to the position shown at the left thereof. At the same time the upper end of the slide 22 engages the corresponding cam plate 21 and withdraws the plate or spring 18 from engagement with the weft carrier butts as indicated at the left in Fig. 2, the lowermost weft carrier being thereafter supported in the cradle 15 in a position to be advanced to transfer position when the cradle is returned to its nor- Havin thus described inv invention it Will be seen that my improvements are of exceedingly simple construction and add no moving parts to the magazine, with the exception of the slight inward bending of the springs 18. Accordingly there is nothing to become displaced or to require adjustment and the device will operate designed for an indefinite period.

Having thus described n v invention, i do not wish to be limited to the details herein disclosed otherwise than as set forth in the claims, but What I claim is 1. In a \veft carrier magazine, an end frame having a plurality of substantially vertical. guide ways for the butts of the Weft carriers, said guide Ways being edective to grip the sides of said Weft carrier butts at the opposite ends of the d ameter thereof during normal operation of the loom. and means to release the grip upon the weft carrier butts upon indication of transfer.

In a weft carrier nnigaziue an end frame having plurality of substantially vertical guide Ways for the butts of the weft carriers, each guide Way having a fixed portion engaging the Weft carrier butts at one side and having a movable portion yieldingly engaging said butts on the opposite side, and means to Withdraw said movable portion and release the Weft carriers upon indication of transfer.

3. In a Weft carrier magazine, an end frame having a plurality of substantially vertical guide Ways for the butts of the weft carriers, each guide Way having a fixed side Wall engaging the Weft carrier butts upon one side and having a longitudinally disposed flat spring plate yieldingly engaging the Weft carrier butts upon the opposite side. and weft controlled means engaging one of said springs upon indication of transfer to bend it outwardly and release the corres ionding Weft carriers.

41-. in a Weft carrier ma azine, an end frame having a plurality of substantially vertical guide Ways for the butts of the Weft carriers one side Wall of each guide Way being fixed and the other side Wall yieldingh engaging the Weft carrier butts, a cam plate on each movable Wall, and an actuating member for each guide Way movable to engage a cam plate upon indication of transfer and thereby Withdraw said movable Wall to release the corresponding Weft carriers In a Weft carrier magazine, an end frame having a plurality of sul'istantially vertical guide Ways for the butts of the Weft carriers, one side \vall of each guide Way being fixed and the other side wall comprising a flat spring plate fixed at its lower end and having its upper portion yieldingly movable inwardly to engage the Weft can rier butts, and means operative upon indication of transfer and engaging said spring plate to withdraw said plate and release the weft carriers.

In testimony whereof I have hereunto a1- iixed my signature,
