Abstract

701,462. Weighing-apparatus. MORTIMER, E. W., and GARRARD ENGINEERING & MANUFACTURING CO.. Ltd. Nov. 16, 1951 [July 20, 1951], No. 17241/51. Class 143 Gramophone pick-ups are weighed by a device comprising a pair of bell-crank levers 34 mounted on fulcra 5, 6 and connected as shown by a spring 10. Pressure is applied manually on a finger piece 14 moving over a calibrated scale 16 until the weight of the pick-up resting on a support surface 3b is balanced as indicated by a pointer 3d on the other arm of the lever 3 being restored to a zero position as seen through a window 11 .in the casing. The device may be mounted on the motor board or turntable of a gramophone.
