DIS'POSAL DEVICE FOR EJECTEDYIEFT CARRIERS fnre/zfar Patented June 24, 1930 UNITED; STATES PATENT @FFICE RICHARD G. TURNER, F WORCESTER, MASSACHUSETTS, ASSIGNOR T0 CROMPTON 86 KNOWLES LOOM WGRKS, OE WORCESTER, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS DISIOSAL DEVICE FOR EJECTED WEET CARRIERS Application filed February 19, 1929.

T his invention relates to an improved de vice for disposing of ejected weft carriers in a weft replenishing loom and is particu larly adapted to a loom in which the weft carriers are ejected from the shuttles by a rearward and substantially horizontal movement.

It is the general object of my invention to provide an improved disposal device by which an ejected weft carrier may be conveyed a substantial distance rearward over intervening mechanism to a suitable can or receiver at the rear of the loom.

It is a further object of my invention to provide a construction by which the disposal device will be maintained in operative relation with the shuttle boxes at all times, as the lay swings forward and rearward.

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

A preferred form of the invention is shown in the drawings in which Fig. l is a side elevation of portions of a double shuttle loom, partly in section, and showing my improvements embodied there- Fig. 2 is an enlarged sectional side elevation of the lay and portions of the disposal device associated therewith;

Fig. 8 is a sectional front elevation, taken along the line 3-3 in Fig. 2; and

Figs. 4 and 5 are sectional front elevations, taken along the lines H and 55 in Fig. 1 respectively.

Referring to the drawings, I have shown portions of a loom frame and a breast beam 11 on which a magazine 12 and transfer mechanism 13 are mounted. I have also shown a lay 15 supporting superposed shuttle boxes 16 in which a pair of shuttles S and S may be operated, the loom being of the double shuttle type.

It will be noted that the shuttles S and S are open at their front and rear sides and that the weft carriers W are transferred therefrom by direct rearward movement through openings 20 in the shuttle box frame 21.

Serial No. 341,156.

The loom is shown as being of a side cam type, in which a plurality of cams are mounted to rotate at the magazine end of the loom and actuate a plurality of levers 31 projecting thereover and suitably connected by links 32 to harness mechanism, not shown.

The can or container C for the ejected weft carriers or bobbins is thus necessarily placed at the rear of the loom and is separated from the shuttle boxes by the cams 30, levers 31 and other mechanism associated therewith.

My improved disposal device is designed to convey the ejected weft carriers IV rearward from the point of ejection to the can or container C.

For this purpose I provide an open trough 40, preferably formed of sheet metal and having raised sides 41 of substantial height. This chute is supported at its front end by a U-shaped hanger 42 (Fig. l) mounted on a fixed rod et l and positioned laterally on the rod by hubs or collars 45, adjustably secured on the rod by set screws 46. The hanger 42 may be secured to the chute 40 by rivets 47, if so desired. The lateral adjustment of the chute permits the chute to be aligned with the shuttles and transfer mechanism.

At its rear end, the chute 4:0 is provided with an inverted U-shaped support hav ing recesses in its lower end portions adapted to rest on and be positioned by the cross rod 52 on which the levers 31 are pivoted. The support 50 is freely slidable axially of the rod 52 in accordance with the lateral adjustment of the front end of the chute.

The front portion of the chute is preferably horizontal, as indicated at 40*, and the rear portion is slightly inclined downwardly, as indicated at 40 At the extreme rear portion, the bottom of the chute is sharply inclined downwardly, as indicated at 54, and an opening 55 is provided through which a weft carrier may drop into the container C. The rear end of the chute is closed by a barrier or end member 56, which is preferably arched over, as indicated at 5'7,

to prevent upward escape of the weft carriers when they strike the barrier 56.

It is desirable to bridge over the gap of varying width between the shuttle boxes and the front end of the chute 40. For this purpose, I provide a connecting chute member 60 (Fig. 2) having depending ears pivoted at 62 on brackets (33 secured to the rear of the lay 15.

The rearward portion of the chute member 60 telescopes within the front end portion of the chute a0 and is preferably supported on rolls 66 mounted on a cross shaft 67 below the chute 40 (Figs. 2 and As the lay moves forward and rearward, the connecting chute member 60 slides back and forth in telescoping relation with the chute 40 and in all positions bridges the gap between the shuttle boxes and the front end of the chute.

Having thus described my invention, the utility thereof will be readily apparent. As the weft carriers \V are forcibly ejected rearward from the shuttles S and S, they pass through the connecting chute member 60 and along the chute 40 at considerable speed, striking against the end member or barrier 50 and dropping downward through the opening 55 to the container C.

As the weft carriers thus travel a sub stantial distance between the shuttle boxes and the container, there is suflicient movement to pull a trailing weft end of considerable length out of the shuttle and shuttle box as the weft carrier IV is thrown rearward. Such a trailing weft end is indicated at E in Fig. 1.

Preferably the weft is cut closely adjacent the selvage at the moment of transfer and it is of very substantial advantage to have the extended travel of the weft carrier by which the rather long weft end will be pulled with certainty out of the shuttle and shuttle box. Difficulty has been heretofore encountered in this respect when the weft carrier has been ejected directly downward to a closely adjacent receptacle, as it was found that if the receptacle was partially filled with empty weft carriers, the dro was not always sufficient to pull the trailing weft end out of the shuttle box, and if left in the shuttle box, it was not infrequently carried back into the cloth, causin a defect therein.

hile I have shown and described a double shuttle loom, it will be evident that my improvements are applicable to any loom in which the weft carriers are ejected rearward.

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 1. In a weft replenishing loom having means to eject a weft carrier substantially horizontally rearward, means to dispose of said weft carrier comprising a chute mounted to extend rearward from the rearward position of the lay to a position over a container placed behind the rearmost part of the loom frame, said chute being mounted on fixed supporting members at its front and rear ends and being positioned above and extending over the cam and crank shafts of the loom.

2. In a weft replenishing loom having means to eject a weft carrier substantially horizontally rearward, means to dispose of said weft carrier comprising a chute mounted to extend rearward from the rearward position of the lay to a position over a container placed behind the loom, said chute having a bottom opening at its rear portion above said container and having a barrier rearward of said opening to limit rearward movement of a weft carrier therein.

3. In a weft replenishing loom having means to eject a weft carrier substantially horizontally rearward, means to dispose of said weft carrier comprising a chute mounted to extend rearward from the rearward position of the lay to a position over a container placed behind the loom, and a connecting chute member movable forward and rearward with the lay and bridging the gap between said lay and said chute in all positions of said lay.

4. The combination in a loom as set forth in claim 3, in which the chute and connecting member are mounted in telescoping re lation.

5. The combination in a loom as set forth in claim 3, in which the connecting member is pivoted to the lay and slides forward and rearward in telescoping relation with the chute.

6. The combination in a loom as set forth in claim 3, in which the connecting member is pivoted to the lay and slides forward and rearward in telescoping relation with the chute, and in which anti-friction rolls support the rear end of said connecting member.

In testimony whereof I have hereunto affixed my signature.

RICHARD G. TURNER.
