Abstract

416,267. Momentum power - storing apparatus. PEACOCK, W. A., c/o Peacock & Sons, Haymarket Lane, Newcastle-on-Tyne. Feb. 20, 1934, No. 5638. [Class 10.] An electromagnetically actuated pendulum a has impulses imparted to it only when its amplitude falls below a predetermined amount. The pendulum is pivoted at band carries a freely suspended pawl k adapted to coact with a grooved tooth m mounted on a spring n fixed at n<1>, supported at q, and carrying a contact r mating with an adjustable contact s. When the pendulum makes full swings, the pawl k sweeps ineffectively over the tooth m, but when the amplitude falls to a certain limit the pawl catches in the tooth and depresses the spring n to make contact at r, s. The circuit through the electromagnet h and a dry battery u is thus made, and the full swing restored to the pendulum.
