Abstract
642,640. Automatic exchange switches. AUTOMATIC ELECTRIC LABORATORIES, Inc. March 14, 1947, No. 17051/49. Convention date, March 15, 1946. Divided out of 642,586. [Class 40 (iv)] In the manufacture of a wiper unit for a uniselector, an annular hub is machined to a width slightly greater than that desired and is provided with a peripheral recess, a wiper blade of thickness less than the depth of the recess is secured therein and the hub is then pressed to the required axial dimension. Pairs of wiper blades 33, Figs. 4, 5 are spot-welded in the peripheral recesses 32 in the hubs 25 which are mounted with intervening insulating washers 28 on an insulating sleeve 24. Recesses 31 on the inner edges of the hubs diminish leakage. The switch described is identical with that of Specification 642,586.
