Abstract

366,729. Hand actuating devices for switches, rheostats, and other wireless apparatus. GRAMOPHONE CO., Ltd., Hayes, and CLARK, G. F., 39, Brandville Road, West Drayton, both in Middlesex. Feb. 10, 1931, No. 4192. [Class 38 (v).] A knob for operating switches, r h e ostats and other components of wireless sets comprises at least two insulating parts 1, 8, the part 1 being attached to the metal spindle 3 of the apparatus by means of a screw 6, and the part 8 being attached to the part 1 insuch a manner as to cover the screw 6. The part 8 may be attached to the part 1 by means of a screw 11 and both screws 6, 11 may pass through threaded metal bushes 4, 12 mounted in recesses in the part 1. In a modification, Fig. 4, the part 1 is mounted on a sleeve 14 which can rotate on the spindle which is fixed, and the screw 6 passes through a hole in the sleeve to engage a groove in the spindle, thus preventing removal of the knob but allowing rotation. A pin 17 on the sleeve 14 engages the movable member of the rheostat &c.
