Abstract

16,191. Taylor, J. Aug. 9. Loom take up motions constructed to avoid the necessity of changewheels. The crank or other regularly rotating shaft is provided with a disk or lever b, Fig. 2, having a slot c, along which a stud d is adjusted by a nut only, or by a screw f, rotated by a box or like key or handle &c. and a locking-nut. Or the stud may be adjusted along a plain rod, the screw f passing through a tapped hole in the stud. The disk b may be provided with graduations or a graduated plate, so that the stud may be set to give any required number of picks per inch &c. The stud is connected by a link i and rocking lever j to a link m, which carries a pawl or pawls p (preferably of different lengths) to rotate a ratchet-wheel s, from which the shaft u of the cloth roller or sand beam is rotated by worm gearing as shown, or otherwise. In a modification, the teeth are provided on the face of the ratchet-wheel s, Fig. 4, which may be provided with safety catches w. The pawls, which may be kept in contact with the ratchet by springs, may be released from the ratchet, to allow of turning back, by pulling strings to which they are connected. The following arrangements are described in the Provisional Specification only : Instead of the rod i, other rods of the apparatus may be adjusted for a similar purpose. A modification is described in which a crank, crank-disk, eccentric, eccentric-disk, &c., is mounted on the crank-shaft and connected to a rod coupled to a pawl lever for actuating the take-up by ratchet- and - pawl and worm gearing, the crank - disk, operating-rods, or levers, or coupling-pins being adjustable. The crank-disk &c. may be graduated and the pawl lever may beoperated from the tappetshaft or lay-sword. Mechanism for stopping the takeup when the weft breaks is described, consisting of a curved plate arranged more or less concentric with the ratchet-wheel and moved by rods &c. connected to the weft-fork hammer to come in contact with the actuating-pawl and disengage it from the ratchet.
