Abstract
657,919. Time switches. WEIBULL, N. R. M. April 5,1949, No. 9232. Convention date, April 16, 1948. [Class 38(v)] A time-switch comprises a spindle 2 having a non-selflocking screw thread 2a co-operating with a nut-wheel 4 driven by a motor 1. Normally the spindle is rotated by the motor 1, but when an electromagnet 6 is energized, an armature 6a is attracted and a brake 8 thereon stops a gear wheel 5 meshing with a portion 2b of spindle 2. Rotation of the wheel 4 then causes the spindle to move axially upwards to open contacts 11, thereby de-energizing the electromagnet 6 and releasing the brake 8 so that the spindle returns under spring or gravity to its normal position bearing on an adjustable set-screw 9. The armature 6a carries mercury switches 13, one of which makes a holding circuit for the electromagnet, and the other the controlled circuit.
