Abstract

216,915. Harrison, G., (Barberis, A.). Feb. 6, 1923. Driving; cases with internal horns; turntables. - Relates to gramophones or the like wherein the motor is arranged beneath the horn and is connected to the turntable by a shaft passing through the horn, and - consists in detachably .connecting the shaft to the upper end of the motor-spindle. In the construction shown, the connecting-shaft H<1> is flexible, and is secured at the top by a detachable pin P to a short shaft N which turns in ball-bearings and carries the turntable M. At the bottom, the shaft H<1> is connected by a pin P<1> to a short shaft Q, also mounted on ball-bearings and having a square socket fitting on to the end of the motor-spindle E<1>; or the shaft H' may be detachably secured directly to the motor-spindle. In another construction, the connecting-shaft passing through the horn C is rigid, and is screwed on to the end of the motor-spindle. The turntable, the shaft H<1>, and the tone-arm &c. may be removed to allow a wireless telephone receiver to be placed over the horn inlet.
