Title: Improved form of control lever
IPC: F16H21/06
Filed: 1939-05-22
Abstract: 576,687. Levers. BOULTON PAUL AIRCRAFT, Ltd. (Soc. d'Applications des Machines Motrices). May 22, 1939; No. 15129. [Class 80 (iii)] [Also in Group XXVIII] A control lever comprises parts 3, 6 normally yieldingly coupled together so as to be incapable of transmitting load, and an electromagnetic clutch for locking the parts rigidly together when load is to be transmitted. The part 3 is secured to the core .2 of a pot electromagnet 1 having a winding 11. The magnet has a disc-shaped armature 4 resting on the upper edge of the pot and having a socket 7 into which is inserted the other part 6 of the lever. The parts are yieldingly connected by a 'tension spring 8 and 'pins 9, 10. When the magnet is energized, the parts 6 and 3 are rigidly connected and force may be transmitted, but when deenergized, application of force to the part 6 merely causes the disc 4 to tilt about an edge of the pot 1. The invention is partcularly applicable to'the control of a wobbler type of hydraulic pump driven by an.'electric motor. When the pump is not running, attempts to move the wobbler may result in bending or breaking 'the lever, but when the pump is running the resistance is much less and it is then that the electromagnet is energized by the current and the lever able. to transmit load.
