COLUMBIA PLANoGRAPx-l CO.. WASHINGTON D L EPA H. RYON, OF WALTH'AM, MASSACHUSETTS, ASSIGNOR TO CROMPTON & KNOWLES Y LOOIVIWORKS, OF WORCESTER, `MASSACHUSETTS, A CORPORATION F MASSACHU- f SETTS.

f zen of the United States, residing at lValtham, in the county of Middlesex and State of Massachusetts, have invented a new 'and useful Filling `Stop-lvliotion, of which the following is a specification.

` This invention relates to a filling stop motion particularly adapted for use on weft replenishing looms. v- In looms of this type a thread vcutter is provided to cut the ends of filling or weft which extend from the selvage as a bobbin is being ejected from the shuttle and a full bobbin is being inserted therein.

It is the principal object of my present invention to provide a filling stop motion which may be applied upon the same side of the loom as the thread cutter above referred to, yand so constructed that it will positively assist in presenting the weft ends to the thread cutter.

`With this object in view, my invention contemplatesfthe provision of a yfilling stop motion adapted to grasp the inserted weft, to vbring' it forward toward the thread cutter and to release the weft near the forward limit of its travel.

n In carrying out my invention, I mount the stop motion upon a movable support, one feature of my invention consisting in the provision of such movable support, together with operating devices by which it is caused to follow the movements of the lay but on a reduced scale.

My `invention further comprises ,certain devices, arrangements and co-mbinations of parts which will be hereinafter described and more specifically pointed out in the appended claims.

A preferred form of my invention is shown in the drawings in which,

Figure I is a sideelevation of my improved stop motion, together' with certain portions of the lloom to which it is applied; Fig. 2 is a side elevation of certain of the parts shown in Fig. 1 but in a different position, and Figs. 3 and l are aside elevation and top plan view, respectively, of certain parts of the stop motionv drawn on an enlarged scale. Y

In Fig. 1V I have shown my improved filling stop motion as mounted upon a movable support made in the form of an upwardly `Specification of Letters Patent.

FILLING STOP-MOTION.'

Patented Aug. 24, 1915.

Serial No. 861,146.

` The grate 20 is fixed to the end of the support p10 and is provided with an upwardly extending flange 22 carrying a stud 23 upon which is piveted the Vhub 24 of the filling forl 2l. y l

'The hub 24 is provided with a downwardly extending arm 25 carrying a laterally projecting pin 26. A spring wire 27 is secured to the support l0 in any convenient manner, as by the screw 28, and normally rests against a stop pin 29. 'Ihe upper end of the spring 27 extends into the path of the pin 26 and acts to yieldingly return the lilling fork to the position shown in Fig. 3. Reference to said figure, however, will show that' the spring 27 will engage the stop 29 before the filling fork reaches its extreme lower position, so that, inits detecting action, thefilling fork is actuated by gravity alone. The fork is thus capable of'very sensitive action upon the inserted weft.

The hub 24 is also provided with an upwardly projecting arm 30 which extends into the path of a stud 31 supported in fixed position on a casing 32 withinwhich a slide 33 vis longitudinally movable. port l0 moves to the rear, the arm 30 engages the stud 3l, as shown in Fig. 2, and raises the filling fork against the resistance of the spring 27. When the support again moves forward, the filling fork gradually descenes under the influence ofthe spring 27 and finally under -the influence of gravity alone, as previously explained.

A forwardly extending horizontal arm 34 on the hub 24: acts as a dagger to engage a depending lug 35 adjustably secured to the slide 33. The lug 35 is .provided with a notch or recess 36 within which the point of the dagger is received when the absence of filling permits the filling fork to descend to the position shown in Fig. 3.

At its forward end the slide 33 is provided with a hook-shaped projection 37 which engages a rod 38 operative through As the supvaov connections of the usual type, notfshown, to Y,

release the shipper and stop the loom when` the slide is moved forwardly.

The lug 35 extends downwardly a short distancevbelow the notch`36, this extension being sufficient to engage the upper surface ofthe dagger 3l as the support 10 nears the forward limit of its travel, whenever the; presence of filling prevents the cooperation of the dagger 3a with the notch 36. The engagement of the extension of the lug 35 with the upper face of the dagger 34 causes the filling fork to be slightly raised, as .indicated in Fig. 1, thus releasing the tension on the filling as the lay and the support 10 reaclitheir forward limits of movement.

The cam 13 is so adjusted that the'lay 15 will begin its rearward movement before the beginning of the rearward'movement of the support l0. As the weft or lling extends from the selvage to the shuttle in the shuttle box, this movementuof the lay carriesthe released filling beyond the end of the lling fork before the fork begins its rearward opening movement.

Many of the advantages of my improved construction can obviously be secured if the grate is mounted upon the lay and only the fori: is mounted upon the movable support.

Having thus described my invention, it will be seen that by mounting the filling stop motion upon a movable' support, vthe movements of which correspond in general to that of the lay but on a reduced scale, I am enabled to grasp the inserted weft and bring it forward into position to Vbe seized by the thread cutter whenever the operation of the thread cutter is desired, while at the same time I have provided means for releasing the filling so that there shall be no interference with the continued operation of the loom except upon the failure or exhaustion of filling in the shuttle.

This form of stop motion is particularly useful on lautomatic looms operated upon the drop box principle, as the usual types of yfilling stop motions cannot be used upon the drop box endV of the loom, and furthermore they have been found to seriously interfere with the action of the thread cutter when applied upon the Qpposite end of the loom.

Having thus described my invention, it will be evident that changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope thereof as set forth in the claims, and I do not wish to be limited to the details herein disclosed, but* What I claim is A, 1. `In a loom having a vframe and a lay, a
