Abstract

233,442. Buckle, H. L. T., and Gramophone Co., Ltd. Feb. 12, 1924. Tone-arm joints; cases with internal horns. - In order to make a gramophone compact, the tone-arm or the like is adapted to be lowered when the machine is not in use, by rotating a tubular bearing on which the tone-arm or equivalent is pivotally supported. The bearing comprises a tube 16 adapted to slide in a fixed sleeve 13 which has a flared end arranged over a reflector 12. In the tube 16 is a slot 17 engaging with a stud 18 fixed in the sleeve 13. The lower end of the tone-arm 10 which is mounted on ballbearings 16<1>, is formed with a slot 24, through which protrudes a lug 25 extending from a tube 23 fixed within the tube 16. When the tone-arm is rotated beyond a given point in either direction beyond the record-playing positions, the lug 25 is engaged by an end of the slot 24. The tube 16 is thus rotated within the fixed sleeve, and, together with the tone-arm is caused by the action of the slot and stud 17, 18 to fall or rise. A spring-controlled ball-catch 21 retains the tube 16 in its uppermost position.
