Abstract

247,216. Watson, T. Feb. 7, 1925, [Convention date]. Brushing records.-Relates to devices for attachment to the soundbox of a sound-reproducing machine, to clean the record when the machine is in action. According to the invention, such a device comprises a metal frame 1 having at one end clamping jaws 2, 3 for securing the device on the edge of the sound-box, the other end carrying an adjustable member 5<b> connected to a brush-holding clip 5. The member 5b is so adjusted on the limb 1<c> of the frame, and secured thereon by a set-screw 5<c>, that the brush 6 sweeps the record groove in advance of the needle during playing. One jaw 2 of the clamp is formed by bending the wire of the frame, the other jaw consisting of a slidable member 3 engaged by a nut 4. The Specification as open to inspection under Sect. 91 (3) (a) also describes a modification in which the brush-holder 5 is connected to the part 5b by a resilient arm, instead of being directly attached. This subject-matter does not appear in the Specification as accepted.
