Abstract

195,673. Billing, N. Pemberton-. July 3, 1922. Actuated by speed regulators. - Relates to gramophones of the kind in which constant linear speed of the sound track of disc records is obtained by an attachment comprising a driven friction wheel engaging the top surface of the record close to the stylus, and a centrifugal governor geared to the friction wheel. According to the invention, the friction wheel is traversed along a straight line passing through the centre of the record. In the construction shown, the friction wheel 41 and the governor are carried by the sound-box 40 which is mounted on a telescopic tone-arm extending diametrically across the record. The governor comprises a disc 46 fitted with friction weights 47 adapted to engage the inner surface of a surrounding drum 42. The weights are pressed outwards by an adjustable spring 49 and by centrifugal action.
