Abstract

12,835. Stothert & Pitt and Stothert, P. K. June 24. Cranes; electrically-actuated apparatus.-Relates to apparatus in which the winding-barrel is connected by a friction clutch with the electricallyactuated shaft on which it is mounted, and consists in operating the clutch by a magnet under the control of the motor-controlling lever. Fig. 1 shows a plan of the apparatus, B being the barrel and D the clutch, preferably of the coil type. The clutch lever D<1> is moved to close the clutch by a magnet E in a circuit which is closed by the first movement of the motor lever. The clutch is opened, when the magnet is de-energized, by a spring D<2>.
