William B. Willard, New York city.--This invention, relating to looms
for weaving narrow ware, consists in the arrangement of a spur wheel
traveling on a fixed rack, and actuating a movable rack attached to
the shuttle carrier. Motion is given to the spur wheel by a cam on the
main shaft of the machine, which acts through a slotted lever and a
connecting rod. The object is to provide mechanism for throwing the
shuttle in such looms. In the loom the shuttlerace is divided at its
center, leaving a space of sufficient width to admit of the passage
and shedding of the warp. The shuttle slides in the race, and is of
such length as to overlap the opening, so that it may pass smoothly
from one section of the shuttlerace to the other. The shuttle is
pierced to receive the fingers of the shuttle carrier, which slides on
the bar. The latter is a piece of sheet metal, which is turned over at
its upper edge to receive the bar, and is provided with guides for the
fingers. The said fingers are capable of engaging with the holes in
the shuttle and project below the piece of sheet metal, and are bent
at right angles, and provided with grooved friction rollers, which
engage with a cam slot of such form that it will draw the fingers, one
at a time, downward out of the shuttle, and retain them below the
warp during the passage of the portion of the shuttle with which they
engage, through the threads of the warp, and replace them after that
part of the shuttle passes the warp.
