Abstract

722,039. Spring-driven bells. ROSSATO, N., and ROSSATO, G., [trading as DITTA FLLI N. & G. ROSSATO]. April 2, 1952 [April 13, 1951], No. 8427/52. Class 13 In a bell in which a spring-driven escapement wheel E oscillates a pallet 3, the pallet consists of a plate having claws 5 engaging the escapement wheel and bent projections 6 holding a U-shaped portion of a wire 7 carrying the hammer 8. The projections 4 on the pallet serve as pivots. The driving spring 12 has a looped end 13 co-operating with a spring 14 frictionally engaging a one-piece drum 11 so that over-stressing of the driving spring 12 is prevented. A manually actuated rack 1 gearing with a sector 2 carrying a pawl G co-acting with a ratchet wheel F is reciprocated to tension the driving spring. When the rack 1 is depressed, the tail 10 of the wire 7 is opposite a notch 31 so that the hammer 8 is free to vibrate.
