Abstract
847,215. Gramophone records. ELECTRIC & MUSICAL INDUSTRIES Ltd. Dec. 14, 1956 [Dec. 31, 1955], No. 37547/55. Class 40( 2). A gramophone record 1 is provided with a removable centre portion 3 with an aperture 4 to receive the standard spindle of a record player, the aperture housing the portion 3 being of a size to receive an enlarged spindle, say of 1¢ inch diameter. Radial arms 6 extend into slots in the body of the record and are held there by frictional engagement. The arms and slots are preferably of dove-tail shape. Arcuate slots 5 between the arms separate the portion 3 from the body 1. To make the record, it may be pressed in a normal record press and when the sound track is formed the slots 5 may be punched simultaneously. A second press is used to sever the arms 6 from the record without punching the part 3 out of the record. In a modification the slots are omitted and the part 3 directly engages the enlarged opening.
