Abstract

1315380 Timepiece escapements LES FABRIQUES D'ASSORTIMENTS R'EUNIES SA 22 Oct 1970 [22 Oct 1969] 50225/70 Heading G3T In an escapement having a lever 6 which carries a guard pin or dart 12 to co-operate with a roller 13 on a roller table 11 of a balance, the dart 12 and the roller 13 are magnetized so as to repel the lever against a corresponding one of banking pins 8, 9. The roller 13 is provided with a recess 14 which has no defined magnetic polarity so that repulsion is substantially zero while the dart passes therethrough. The lever 6 also carries a fork 7, which co-operates with an impulse pin 10 on the roller table 11, and pallets 5 which engage teeth 2 of an escape wheel 1. The arrangement is stated to eliminate the need for draw action of the lever 6 and recoil of the wheel 1, and the faces 5a of the pallets are tangential to a circle about the axis of rotation of the lever.
