Weft-fork.


Weaving.) a. One used in certain kinds of looms where the filling is laid in, one piece at a time. See slat-weaving loom.

b. An arrangement for stopping the loom if the weft-thread should break or fail. The original stopmotion.

It was invented by James Bullough. English patent enrolled July 14, 1841.

“In the end of the reed three or more wires are inserted, and when the stay moves the reed forward to heat up the weft, the forks of an elbow-forked lever enter between these wires, and, being pressed against the weft, are forced back a little, thereby raising the hooked end of the lever, which is the heavier. But when the weft-thread fails, the forks project through the wires, and the hooked end of the lever falls by its own weight, and is caught by another hook, formed in the segmental head-piece of a vibrating lever and drawn back. By this movement a horizontal lever is made to strike the knocking-off rod, which shifts the belt from the fast to the loose pulley, and lifts the click of the taking — up apparatus out of the teeth of its ratchet-wheel.”
