Abstract
653,236. Supporting gramophone pick-ups. BISHOP, J. Dec. 6, 1948, No. 31525. [Class 40 (ii)] The needle in a gramophone pick-up may be raised from or lowered on to the sound track where desired by means of a lever B which engages an arcuate plate C<SP>1</SP>, secured to the tone arm C, through a rod N. The rod N is movable vertically within limits within a support M and when lowered preparatory to contact of the needle with the record abuts at its lower end against a pivoted lever 5 extending at the other end into the path of a stud 6 on the turn-table. A lever 7 is pivoted at the same point as lever 5 and the two levers engage each other frictionally. A small arm 9 on the end of lever B engages a fork on lever 7. The record is adjusted on the turn-table until the marked portion of the record where reproduction is to commence lies between the stud 6 and the record centre. A distance rod G, as in Specification 589,996, is adjusted so that the needle is over the desired groove and the turn-table rotated until the pin 6 is just in advance of the end of the lever 5. The motor is started and reproduction begins as soon as the stud 6 striking the lever 5 has moved its other end from beneath the rod N. To stop playing, the lever arm B is lowered so that the support M, the rod N and consequently the tone arm are raised. Simultaneously lever 7 is moved towards the turn-table over the surface of lever 5, the latter being prevented from further movement in this direction by a stop 12. The arm B is then raised so that the lever 5 is swung into its original position by frictional engagement with the lever 7. At the same time the rod N passes through a notch 7a in the lever 7 until its end comes to rest on the lever 5.
