Abstract

1,165,682. Locking knobs. A. C. COSSOR Ltd. 15 March, 1967 [6 May, 1966], No. 20191/66. Heading F2E. A locking device for a knob 3 of a potentiometer 1 attached to a frame 2 includes a fixed resilient ring member 8 disposed about a spindle 4 of the knob so as to fit within a ring 7 provided in a recess in the knob 3 and an independently rotatable locking member 11 having a plurality of symmetrically-arranged radial extensions 13 such that, on rotation of the locking member 11 from the position shown, the ring member 8 is pressed into engagement with the inner wall of the ring 7 to lock the knob in any desired angular position.
