Abstract

246,328. Poolman, C. G. N Feb. 19, 1925. Addition to 230,207. Systems for continuous-current motors; controlling extent of travel.-In the invention of the parent Specification wherein a motor-controlling polarized switch is energized after the manner of a Wheatstone bridge, the switch is replaced by an arrangement comprising a polarized relay 1 and two electromagnetic switches 12, 13 which have contacts 22, 23 adapted to short circuit the motor armature when the relay is de-energized. The polarized relay may be of a type resembling a galvanometer, or may have a moving coil disposed like a dynamo armature, the terminals of the coil being connected, as in the parent case, to the master side 3 and the follow-up side 4 of the Wheatstone bridge arrangement. The response of the relay makes a contact 6 or 7 and thus brings about actuation of the switch 12 or 13 so as to break the motor short-circuit and send current from the supply 24 either in the forward or reverse direction. In a slightly modified arrangement, double-pole switches replace the single pole switches 12, 13. 0
