Abstract: 383,940. Magazine gramophones. SPARKSWITHINGTON. CO., Jackson, Michigan, Ohio, U.S.A.-(Assignees of Winchell, A. B. ; 906, Oakridge Drive, Jackson, Michigan, U.S.A.) Feb. 24, 1931, No. 22690/32. Convention date, April 26, 1930. Divided on 383,640. [Class 40 (ii).] In a magazine gramophone of the kind described in Specifications 383,640 and 383,939, wherein the turntable descends and ascends at the changing of a record, the pile of records of different sizes are supported on a slide at the bottom of a hopper and the bottom record is fed and positioned by traverse of the slide to position it over the ascending turntable. The fed record according to its size positions the. tone-arm in correct starting position. The slide 123 is supported at the bottom of a hopper 1131 on rolls 129 and reciprocated.to feed the bottom record by the motor 1 driving, the turntable, which motor through a clutch rocks an arm 104, connected by link 106<1> and lever 107<1> to rock, a shaft 108<1>. This shaft engages by a yoke 119 and adjusting screws 117<a> a lever 118 movable between adjustable stops 116<1> and. engaging a lever 121 pivoted at one end to the slide and at the other to a slotted bar 124 which engages a pin 127 on the hopper casing by a notch at one end of the slot 125 in the bar. In these circumstances, a 10" record is correctly fed by the swinging action of the lever 118, and the record is centralized by the diverging ends of two plates 130 fixed on top of the slide. When a 12" record is being fed, its periphery engages and rocks pivoted spring- controlled levers 131, 132 on the hopper casing, causing the rear end of lever 131 to press on the slotted bar 124 so that its notch is clear of the pin 127 on the casing. This results in lost motion due to the bar 124 riding on the pin through the length of the slot, whereby the slide is advanced to the necessary less extent to position the larger record on the turntable. Such record also operates a trip or the like to control the correct positioning of the tonearm for that size of record. The pin re-engages the notch on the return motion of the slide, which is then in order to feed either size of record.
