Abstract

822,453. Automatic gramophones. FOSTER - MALLARD Ltd. June 4, 1958, No. 17 882/58. Addition to 814,974. Class 40 (2). In an apparatus as in Claim 1 of the parent Specification the reversible electric motor is replaced by a non- reversible motor coupled to reversible transmission means. The reversing means comprises an arm 194 and a jockey pulley 195 thereon which is inserted between or withdrawn from between the motor shaft 29 and a tyred wheel 31 engaging the rim of the turntable every time a finger 116 is engaged by a abutment 117 on a toothed disc 33. The direction and reversal of drive of the turntable is in dependence on the direction of rotation of the disc 33.
