1,150,689. Rack for recording discs. H. V. NEYROUD. 2 April, 1968 [4 April, 1967], No. 15810/68. Heading A4B. A storage rack for sound recording discs 3 comprises a row of vertical arms 11 spaced by the thickness of a disc 3 and each provided at its rear end with a cradle 12 for supporting a disc 3, a rack element 17 secured to the frame 2 of the rack at the rear thereof and comprising a series of strips 18 between which the lower parts of the cradles 12 move and a key board at the front of the frame, each key 16 being adapted to raise an arm 11 when depressed. The arms 11 are supported in lowered positions by the ends of the arms resting on the tops of the rack strips 18, and the arms are supported in raised positions by elastically deformable lugs 30 on the strips 18 cooperating with bosses 31 on the cradles 12. Each cradle 12 also has a transversely extending rib 23 which prevents the wedging of a disc 3 between the cradle and the adjacent arm 11. Each key 16 is mounted on a lever 14 pivoted on a common pin 13 and the other end 20 of the lever engages in a notch 19 in the front portion of an arm 11. The front ends of the arms 11 are provided with further cradles 15 and with guide fingers 21 co-operating with a channel 22 of the same width as the fingers in the front of the frame. A boss 24 on each arm applies the disc supported by the adjacent arm against the latter. A rib 26 prevents the operating lever 14 from engaging in a neighbouring notch 19. Bosses 27, 29 on each cradle 15 co-operate with grooves 28, 25 in the adjoining cradle. |
