Abstract

139,580. Waylen, L., and Rose, M. Feb. 14, 1919. Bell clappers and other strikers; bell - operating mechanism, hand or foot. -Relates to bells having the hammer mounted on a spring and carried to oscillate so that, when the tension is released, the hammer strikes the sounding-member. The spring is coiled to form a helix a having a central portion d bent outwards to form a pawl, one end c of the spring being anchored to the base, while the other end b carries the hammer. The spring may be made in one piece or in two parts secured together. The helix a is mounted on a pivot e, and the pawl d engages with the teeth h of a ratchet-wheel mounted on a separate axle g'. The ratchet-wheel is operated directly by hand or by means of a curved or straight rack engaging with a pinion on the ratchet-wheel.
