Embodiment Construction

[0011] The accompanying drawings show the detent escapement forming the subject of the invention. The detent escapement comprises an escape wheel 2 with teeth 3 . Although not shown, the escape wheel 2 is driven by a transmission train of a timepiece that receives driving force from a barrel. Disc 1 is mounted on a balance shaft 16 not shown in the figure. The disk 1 comprises a large disk 4 on which an impact shoe 5 is mounted and a small disk 23 with a circular periphery 24 in which a recess 22 with a rising edge 25 is formed. The first actuating claw 14 is installed on the top of the large disc 4 . The figures show that the finger 14 protrudes from a disc 75 sandwiched between the discs 4 and 23 . The escapement also includes a locking member 6 in the form of a rod hinged on a pin 8 . The lock 6 comprises a first part and a second part fixedly connected by a pin 8 . The figures show that the first part comprises a locking device 80 cooperating with the tooth 3 of the e...

Abstract

The detent escapement has balance staff (16) mounted with roller (1). The roller includes large roller (4) fitted with an impulse pallet stone (5) and small roller (23) provided with notch (22) at its circular periphery (24). The roller includes a control finger (14) and follower (20) ending in a beak (21) arranged for cooperating with the notch of the roller. The roller has safety finger (95) arranged for cooperating with the teeth of the escape wheel (2), and for locking the wheel, when the impulse pallet-stone is accidentally unlocked from the tooth of the wheel.

Description

technical field [0001] The invention relates to a detent escapement for a timepiece, comprising an escape wheel with teeth, a balance wheel to which at least one disk is fixed on its balance shaft, and a pin hinged on a pin A locking member in the form of a rod on the disc, wherein the disc includes impact pads and is formed with notches on the circular periphery of the disc; the locking member has means for locking the escape wheel, A control finger and a follower terminating in a beak arranged to cooperate with a recess of said at least one disc. Background technique [0002] A detent escapement conforming to the above description has been proposed in Swiss Patent Application No. CH 641 / 75. Timepieces incorporating detent escapements are highly appreciated for their precision. However, a very important disadvantage of detent escapements is that they are very sensitive to shocks. Therefore, they are considered unsuitable for watches. In fact, if the watch is subjected t...
