Abstract

1,085,211. Gramophone trip mechanism. GERRARD ENGINEERING Ltd. Feb. 11, 1965 [Feb. 21, 1964], No. 7357/64. Heading G5R. A trip mechanism for a gramophone incorporates a magnetic arrangement which prevents the possibility of early tripping during the play of a record. During play a trip control member 1 is urged toward an abutment 14 mounted on the rotary drive shaft by the movement of the gramophone pick-up arm 19, and the abutment is so shaped that when it engages the arm this is pushed upwards to operate the trip mechanism 18. Two magnets 5 and 6 are arranged one on the arm and one on the rotary shaft, and when these come into proximity the arm is repelled as far as the mechanism allows, so that premature operation of the tripping mechanism is avoided. A further abutment 16 at a higher level pushes the arm away after a tripping operation has occurred.
