Abstract

1435566 Escapements BUNKER RAMO CORP 8 May 1973 [29 June 1972] 21945/73 Heading G3T In a pin pallet escapement, each of the pallet pins 31, 32 comprises an active portion cooperating with the teeth 30 of an escape wheel 18 and formed by a lobe projecting from a larger reinforcing portion which is located on the side of the pin away from the escape wheel axis. As described the lever is moulded from an acetal copolymer resin integrally with the pallets and with a fork (35) Fig. 2 (not shown) and guard pin (33). The latter co-operate with a similarly moulded roller and impulse pin unit (21) on a balance. The pin design shown gives clearance as at A and 43 to the escape wheel teeth during forward motion of the wheel and protects the pins in the event of reverse wheel motion Fig. 3 (not shown).
