Abstract
316,243. Bilantz, D. S., and Watts, P. T. April 26, 1928. Brakes. - Automatic stop mechanism of the kind operated by a cessation or change in the feed movement of the tone-arm has a first member or lever 1 moved by the tone-arm and a second member or lever 2 carried on the first member and driven by the motor mechanism to move synchronously with the tone-arm during playing, but adapted, upon cessation or change of movement of the tone-arm, to move in a path which is other than parallel to the path of movement of the tone-arm to operate mechanism causing a brake to be applied. The Figure shows the position of the parts during playing. The lever 1, moved by the tone-arm about the pivot 1', carries on a pivot 3 a lever 2 driven by a pinion 6 from the motor. The levers 1, 2 move synchronously about the pivot 1<1> until the tone-arm stops or changes its movement when the lever 2 moves relatively to the lever 1 about its own pivot 3 and by its projection 2<11> operates a lever 19 to release a trigger 17 retaining the arm 13 of the three-armed brake lever 13, 14, 12. This allows a spring 28 to move the brake lever, the arm 14 of which applies the brake 21<2> whilst the arm 12 moves the pinion 6 out of engagement with the rack 5 on the lever 2. The brake is removed to start the machine by a projection 24 on the lever 1 which is swung across when the tone-arm is moved to starting position. The pinion 6 is driven from the motor by a spring drive and a spring tends to return the pinion to the bottom of the groove 8.
