Abstract

840,783. Disc record adapters. DEUTSCHE GRAMMOPHON G.m.b.H. Dec. 10, 1957, No. 38401/57. Class 40 (2). A record adapter comprises a central portion 1 which has a hole 7 (0.285 dia.) and three radial arms, the outer end of each of which has two resilient limbs 3 each grooved as at 6. When the adapter is in position in a record the limbs 3 are forced back to the position shown in dotted lines in Fig. 1. Studs 5 in each radial arm ensure the transmission of drive from one record to another.
