Abstract

140,990. Rodway, J. I. Nov. 12, 1919. Periodic.-Relates to a springless brake such as that described in Specification 14002/14. A plate 4, which is screwed to the top of a gramophone cabinet, carries a post to which is attached a brake lever 1. To one end of this lever is fixed a pad 8 curved eccentrically to the pivot of the lever 2, and to the other end an upright rod 12, on which is screwed a conical contact-member 17. At the close of a record the tone-arm presses against the contact-member, which is made of fibre, vulcanite, or the like, thus bringing the pad into contact with the edge of the turntable, which tends to carry the pad round, thus increasing the brake pressure. The pad may be arranged on the brake-lever as in Specification 14002/14.
