Abstract

1424681 Automatic record player GLENBURN ENG Ltd 19 April 1973 [20 April 1972] 18291/72 Heading G5R Pawl member 18, pivotally mounted on the usual cam gear wheel 10, is moved to bring its part 22 into engagement with an abutment 5 rotating with the record player turntable whereby the wheel 10 is rotated into drive engagement with pinion 12, also rotating with the turntable, to initiate an automatic record change or switch off of the player. The pawl member is moved by T-shaped operating member 30 which is pushed left to right on the wheel 10 as rod 39 coupled to the pick-up arm engages the rounded cross part 38 of the member when the arm approaches the end of record play. The pawl member 18 includes hemi-spherical part 29 on an extension 28 of its arm 23 which frictionally engages the underside of the operating member and also a resilient arm 26 which is engaged by a nose part 37 extending from the rounded cross part 38 of the operating member. During the cam gear wheel rotation, pins 41 on the underside of the record play deck plate engage a lip 40 on the T-shaped operating member to restore the member to its initial position, extension 35 on the member at the same time pivoting the pawl member back to its start position.
