Abstract: 622,225. Selector switches. STANDARD TELEPHONES & CABLES, Ltd. May 16, 1946, No. 14812. Convention date, June 1, 1945. [Class 40 (iv)] A selector switch comprises two separate band drives for traversing a brush carriage respectively in two opposite directions over a terminal bank. A continuously rotating vertical shaft 19 in a rotary telephone exchange system drives a flexible gear 20, which is warped to ineffective condition when a magnet 22 is de-energized. The gear 20 carries with it an arm 60 bearing a member 65 spring-pressed outwardly to form a driving connection to one or other of two pulleys 44, 45 connected by flexible bands 52 (or 58, Fig. 3, not shown) to a front and a back portion respectively of a projection 57 on a brush carriage 1. With the carriage 1 initially in right-hand position, energization of the magnet 22 causes the flexible gear 20 to be driven, and as the arm 60 rotates from the right-hand position in Fig. 5, the lower of two rollers 69 on the member 65 engages a groove 72 on a connector member 71 to drive the lower pulley 45 clockwise, whereupon the carriage is moved from right to left, the upper pulley being driven idly in the opposite direction by its band connection. When the carriage reaches left-most position, its brush-changing members 74 engage an abutment 75 to change the brushes, and at the same time the upper roller 69 engages a cam 73 on the upper connecting member 71 to force the member 65 inwardly, whereupon the lower roller 69 is withdrawn from its groove 72 and the upper roller engages a corresponding groove 72 in the upper connecting member so as to drive the upper pulley 44 in a clockwise direction and return the carriage. A similar change-over takes place when the carriage returns to home position. In a modification, Fig. 9, the changeover is effected by engagement of a cam-finger 76 on the member 65 with an external fixed roller 77. Specification 606,238 is referred to.
