Toull whom it may concern.

Be it known that I, EARL J. VVENTz, a citizen of the United States, residing at Danville, the county of Pittsylvania and State of Virginia, have invented a new and. useful lVeft-Carrier- Magazine, of which the following is a specification.

This invention relates to a Weft carrier magazine of the stationary type in which a plurality of parallel vertical compartments are provided for storage of different kinds of weft carriers. It has been found desirable to provide means by which angular movement or vibration of the weft carriers will be restrained, in order that the weft ends may not become entangled.

It is the general object of my invention to provide improved devices for restraining such angular movement'of the weft carriers, together with additional means for at times holding said devices out of operation. In the preferred form of my invention, I also provide means for releasing said devices upon. indication 'of transfer.

My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed outin the appended claims.

A preferred form of the invention is shown in the drawings in which Fig. 1 is a front elevation of parts of a weft carrier magazine embodying my improvements Fig. 2 is a plan view of the parts shown in Fig. 1;

Fig. 3 is a front elevation of certain of the parts shown in Fig. 1, the parts being in a different relation;

Fig. 4 is a detail side elevation, looking in the direction of the arrow 4 in Fig. 3;

Fig. 5 is a perspective view of one of the sliding weights;

Fig. 6 is a perspective view of one of the locking plungers or latches and of a portion of a releasing member; and

Fig. 7 is a perspective view of one of the plates which hold the weights in position.

Referring to the drawings, I have shown portions of a four color stationary weft carrier magazine comprising a frame 10 having vertical compartments 11 formed thereon to receive the butts of the bobbins or weft carriers W. Weights 12 are mounted to slide in each of the compartments 11, these weights 12 being arched on their lower sides as indicated at 13 to engage the upper portions of the bobbins in the compartments. The pressure of the weights 12 upon the bobbins is sufficient to I its compartment by a plate 15 (Fig. 7)

which is detachably secured to the magazine frame 10 and which has a projection or flange 16 which extends slightly beyond the edge of the compartment and prevents displacement of the weight 12. Lugs 17 and 18 of the plate 15 also prevent movement of the block 12 beyond the ends of the compartment in either direction. Upon the back side of each weight 12 there is provided a bevelled or inclined recess 20 and a notch 21 for purposes to be described.

A plunger 22 is mounted to slide in a bearing on a bracket 23 at the rear of each compartment 11 and is yieldingly pressed toward the compartment by a spring 24. As a weight 12 is raised, its plunger 22 is forced rearward by the inclined surface 20 of the weight andthereafter snaps into the recess 21 to lock the weight in raised position. This automatic locking of the weight in raised position is of great convenience to the operator when re-filling a magazine compartment.

Each plunger 22 is provided with a longitudinal slot 25 through which extends a releasing cam plate 26. This plate extends downward and at its lower end is pivoted at 27 to the rocker 28 by which the weft carriers are released from their compartments upon indication of transfer.

The rocker 28 receives a downward movement immediately upon indication of transfer which is thereafter followed by an upward movement by which the slides or cradles which support the weft carriers are returned to normal position. For a more complete description of the operation of this mechanism reference is made to the prior patent to Eppa H. Ryon No. 1,080,748.

The cam plate 26 is provided with a cam surface 29 which engages the end of the slot 25 and withdraws the plunger 22 as the rocker 28 is moved downward. A releasing plate 26 is provided for each of the plungers 22 and weights 12 and I thus insure the simultaneous release of all of the weights whenever a weft carrier is released for transfer.

It is thus certain that even if the operator leaves the weights locked at the tops of the compartments, nevertheless they will be released upon the next transfer of any kind of weft carrier, an event which will never be long delayed.

In order to limit the rearward movement of the plunger 22, I provide a cotter pin 32 positioned in the slot 25 and engaging the bearing bracket 23.

Having thus described my invention, the operation thereof will be readily apparent. The weights 12 when raised to the tops of the compartments are automatically locked in raised position, from which they may be conveniently released manually by swinging the cam plates 26 to the left to the position shown in Fig. 3. If the weights are not thus released by the operator, they will be automatically released upon the next indication of transfer.

Having thus described my invention and the advantages thereof, 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 Y 1. A weft carrier magazine having, in combination, a plurality of weft carrier compartments, a plurality of weights, each vertically slidable in one of said compartments, and a separate latch to automatically lock each Weight in raised position when lifted to the upper end of its compartment.

2. A weft carrier magazine havin in combination, a plurality of weft caiirier compartments, a plurality of weights, each vertically slidable in one of said compartments, separate means to automatically lock each weight in raised position when lifted to the upper end of its compartment, and automatic means to thereafter release said weight upon indication of transfer.

3. A weft carrier magazine having, in combination, a plurality of weft carrier compartments, a plurality of weights, each vertically slidable in one of said compartments, separate means to automatically lock each weight in raised position when raised to the upper end of its compartment, and automatic means to release all of said weights upon indication of transfer.

4. A weft carrier magazine having, in combination, a plurality of weft carrier compartments, a plurality of weights, each vertically slidable in one of said compartments, and a plunger yieldingly mounted to slide transversely in each compartment, said plungers engaging and holding said weights in raised position.

5. A weft carrier magazine having, in combination, a plurality of weft carrier compartments, a plurality of weights, each vertically slidable in one of said compartments, a plunger yieldingly mounted to slide transversely in each compartment, said plungers engaging and holding said Weights in raised position, and mechanical means to periodically release said weights, said means being also operable manually to release a selected weight.

In testimony whereof I have hereunto affixed my signature.

EARL J. VVENTZ.
