Abstract

793,333. Gear for stopping machinery. DODGE MANUFACTURING CORPORATION. March 12, 1956, No, 7694/56, Class 80 (2), [Also in Group XXXVII] An overload release for a belt drive 14, Fig, 1, to a unit 2 which is subject to torque reaction, such as a speed reducing gearing from the pulley shaft 3 to a driven shaft 1, comprises a torque arm 17 pivoted to the unit 2 at 18 and to a fixed point at 19 which is held in extended position to maintain the belt tension by a detent, which detent is adapted to be released at a predetermined value of the torque to release the belt tension and thus stop the drive. The detent comprises balls 29, Fig, 5, loaded by springs 32, 33 between a sleeve member 25 and a telescoping rod 22 of the torque arm 17, which arrangement allows for the arm operating in tension or compression. The rod 22 may also operate with its end portion 58 on electric switch 45 controlling an electric driving motor 13, Fig 1, to stop the motor on the device coming into operation Specification 729,858 is referred to
