wheel (fr when the weft-fork fails to engagea weft-th read, thereby instantly arresting the feed of the take-up roll and warp let-off. The lever K is for the purpose of being operated by the swell-actuating mechanism to throw off the starting-lever L, as is well known, and in the ordinary loom it is also arrangedto be operated by the movement of the weft-forkybut when my cloth-take-up stop-motion is used in combination with the weft-replenishing mechanism I prefer to arrange this lever K so it will not be operated by, the weft-fork, as I do not wish to stop the loom, but only desire to stop the forward movement of the goods when the weft-thread runs out and at the same time operate the replenishing mechanism to drive a full cop or bobbin into the shuttle. To allow this fork-plate (Z to reciprocate in the guide plate (Z and be held in place by and without acting on the lever, I cut a groove transversely through both of said fork and guide plates and insert a linger K, which projects from the end of the shipper-lever K and lies across this guide-plate and holds the fork-plate from coming out.

The weft-fork is operatively connected with the weft-replenishing-actuating mechanism through the shaft r, to which shaft the dog R is connected from the fork-plate d. v This shaft runs across the front of the machine (see Fig. 1) under the breast-beam to the end of the loom on which the replenishing mechanism is located. The arm w is fixed to the outer end of this shaft and has a roll in its lower end which engages the inclined end of the lever T. T his lever is pivoted near its center at w and. is connected at its inner end to red g, which acts to raise the lever g out of engagement with the plate a and actuates the replenishing mechanism in the manner illustrated and described in my patent issued March 18, 1902, No. 695,696. The balance weight 1" is hung on shaft -r (see Fig. 3) and is for the purpose of returning the weft-fork and the rest of the mechanism hung on said shaft to its normal or rest position after having been thrown out by lever o.

The operation of my invention is further explained as follows: By my method of connecting the weft-fork plate d to the clothtake-up-actuating mechanism as above described the weaving of thin places in the My device for accomplishing this is extremely simple and effective in its construction and operation and has proved itself very effective when used in connection with this type of weft-replenishing type of loom, as it allows the loom to continue running while the shuttle is being replenished, but stops the goods from feeding ahead until the shuttle is again laying the filling into the web correctly, when the cloth automatically starts feeding ahead again.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is r 1.
