Abstract

221,964. Tipper, A. D., and Taylor, F., (trading as Tipper, A.). Oct. 6, 1923. Axle-pulleys. - In ball-bearing sash pulleys in which a pulley wheel B is provided with circular grooves in each side face which co-operate with similar grooves pressed in the side frames e to form races for the balls h, adjustment is effected by a screw or a rivet passing through a clearance hole in the pulley. The screw j passes through a clearance hole in one cheek and screws into the other while the rivet passes through clearance holes in both cheeks and is hammered up to effect the adjustment.
