Abstract
21,337. Benson, A. Oct. 21. Door bell alarms.-A bell 4 mounted on a casing 1 fixed on the inside of a door D is operated through a train of gearing by a spring 23 put under tension automatically when the door closes or by a push P. The push or other lever is connected by a bell-crank 24, 25 with a lever 19 attached to the spring 23 and connected through a curved slot 21 in the casing 1 with a lug 7 on the sleeve 5 formed with a ratchet 6. When the door is closed or the push P forced inwards, the spring is put under tension while the teeth of the ratchet 6 slip under the pawl 8 carried by the gear. Upon opening the door or releasing the push, the ratchet 6 moves in the opposite direction under the action of the spring and, through the gear, operates the striker of the bell.
