Abstract
399,081. Sound-recording machines. GALLI, U., 10, Rue Faraday, Paris. Feb. 8, 1933, No. 3884. Convention date, Feb. 9, 1932. [Class 40 (ii).] Relates to devices for using an ordinary gramophone for making records on blank discs, in which the sound-box 5 is traversed across the blank by means of a traction element engaging a screw 14 which is mounted in a frame 10 supported at one end on the machine casing and at the other end engaging the turntable spindle, the screw being driven by a friction-wheel 15 thereon in contact with the blank. According to the invention, the frame 10 is supported loosely on the casing by a foot 13, and the sound-box or tone-arm is connected loosely by a wire 20 or by a rod to a half nut 16, which engages the screw and is slidably guided in the frame. The wire or rod 20 passes through an eye 19 on the frame, which has an apertured lug 11 engaging with the spindle 7. The nut is carried by a member 17, guided by a rod 18 on the frame, and has an extending arm 25 which acts by its weight to keep the nut in mesh with the screw, and also serves as a lifting handle. In the construction shown, the wire 20 is connected by loops to a hook on the member 16 and to the needle holder 23 of the sound-box. A modification is described, in which a rigid rod is connected to a collar on the tone-arm.
