Abstract

1309623 Driving gramophone turntables BORG-WARNER CORP 19 April 1971 [7 April 1970] 25885/71 Heading G5R In an audio-visual teaching apparatus, e.g. of the type described in Specification 1,185,773, the driving means C<SP>1</SP> is disengaged from the turntable P as the latter returns to its home position at the end of a revolution. As shown, the output shaft 220 of an electric motor 87 is in continuous engagement with the rubber-tyred periphery 218 of a wheel 217 and thus drives, through an axle 214, a second rubber-tyred wheel 215 which is urged towards a peripheral flange 89 of the turntable P by a spring 222. A lever 200 having depending tabs 93<SP>1</SP> and 205 is pivoted at 201 to the lower face of the turntable P and its movement relative thereto is limited by a stud 202 projecting from the lever into a slot 203 in the turntable. Momentary withdrawal of a stop 92a<SP>1</SP> from engagement with tab 93<SP>1</SP> allows the turntable to revolve. After one revolution, tab 93<SP>1</SP> strikes the stop 92a<SP>1</SP> again and tab 205 engages a curved tab 206 at one end of a bell-crank lever 207 which is thereby rotated so as to pull a link 212 which withdraws the driving wheel 215 from the turntable flange 89, which is braked by a cam 95 as described in Specification 1,185,773.
