Abstract

The escapement includes a large roller 4 carrying an impulse pallet stone 5 surmounted by a first finger-piece 14 and a small roller 23 in which a notch 22 is made. A blocking member carries, on the one hand, means 80 for locking the escape wheel 2, and on the other hand, a second finger-piece 11 arranged for cooperating with the first finger-piece 14, said blocking member also including a follower 20 ending in a beak 21, said beak acting on the small roller and particularly with notch 22 which is made therein. The first and second finger-pieces 14 and 11 are respectively rigidly secured to the table roller and the blocking member.

Description

technical field [0001] The invention relates to a detent escapement for a timepiece, comprising an escape wheel with teeth, a balance wheel on which a disc is fixed on its balance shaft, and a lock in the form of a lever hinged on a pin The stopper, wherein the disc includes a large disc with an impact fork and a first actuating claw installed on the upper part and a small disc with a notch formed in the outer circumference of the circle, the locking part has There are means for locking the escape wheel, a second actuating dog and a follower ending in a beak arranged to cooperate with the rising edge of the notch of the small disc. Background technique [0002] A detent escapement conforming to the above description has been proposed in European Patent Application No. 03027929.3, filed 4 December 2003. However, in this patent application an elastic member acts on one of the actuating fingers - in this example the first finger forming part of the balance disc - so that when ...
