Abstract

193,752. British Thomson - Houston Co., Ltd., (General Electric Co.). May 8, 1922. Cases; turntables; driving and speed-regulating. A gramophone has a cylindrical casing 1, the cover 8 of which constitutes the turntable. The motor is of the electric induction type, such as is described in Specification 17247/15, having a ring 10 of copper or the like depending from the turntable and stationary coil members 13, 14 supported from the inner walls of the casing. The turntable spindle 3 is mounted in a lower bearing 2 in the base of the casing and in an upper bearing 4 supported, by legs 5, 6. The spindle 3 drives a centrifugal governor 26 controlled by an adjustable friction pad 29. An external bracket 35 supports the tone-arm. Feet 63 provided with felt pads are formed on the base of the casing.
