Abstract
340,381. Gramophones. CARROLL, J., 19, Hall Street, Gorton, Manchester. Nov. 20, 1929, No. 35449. [Class 40 (ii).] Brakes.-A secondary needle-carrying arm is displaced by the tone-arm at the end of the reproduction from a record to apply braking means to the turntable. As shown, a secondary arm a carries a needle b which normally runs in the continuous track c provided near the centre of the record d and is hinged at h to a vertical spindle g, Fig. 2, around which is coiled a torsion spring f, An arm i carrying a brake j is adjustably secured to a slotted plate k. connected to the spindle g so that the brake j moves in unison with the arm a. When the tone-arm m moves to bring the stylus o into the continuous track c, the needle b is displaced by the sound-box n and the arm a is moved under the action of the spring f to apply the brake j to the turntable e. The arm a is so hinged to the spindle g that it can be rotated vertically to permit a change of record without releasing the brake j. The Provisional Specification also refers to an arrangement in which the torsion-spring f causes the arm a, when moved out of the continuous track, to rise and lift the needle clear of the record.
