Abstract

629,273. Gramophones. MALLETT, E. S., and SPEAR, D. F. Aug. 30, 1946, No. 26175. [Class 40 (ii)] In an automatic brake for a gramophone a tap-tap 8 lever is frictionally coupled to an actuating fork 7 controlled by the pick-up arm, both the tap-tap lever 8 and the actuating fork 7 being mounted on a boss 4 carried by a control lever 2 which operates the brake. The control lever 2 is pivoted about a point 3 on the baseplate 1 and is coupled by a pin-and-slot connection to a bell-crank lever 14 which is pivoted about a point 15 and applies or releases a brake in a known manner.
