Patent ID: 7959350

Claim:
A control mechanism for a simple three-cycle chronograph, comprising: a single pusher (A), whereby said pusher comprises a follower ( 4 ) with two noses ( 2 , 3 ) mounted to oscillate on the pusher (P) and subjected to an elastic return action ( 7 ), wherein the noses ( 2 , 3 ) of the follower ( 4 ) work with slots ( 8 , 9 , 10 , 11 , 12 ) that a shuttle ( 1 ) comprises in its peripheral thrust zone (Z 3 ), wherein said shuttle ( 1 ) is pivoted around its pivoting axis ( 0 ), and wherein between actuations of said shuttle ( 1 ) by the pusher, said shuttle ( 1 ) is kept in one of three angular positions, i) resetting to zero, ii) starting, and iii) stopping, by way of a jumper(s) working with three notches (e 1 , e 2 , e 3 ) of the periphery of the shuttle ( 1 ), the whole being arranged such that for each depression that is exerted on the pusher (A), the shuttle ( 1 ) passes from one position to the next in its operating cycle, from resetting to zero during operation, then operating with stopping, and finally stopping with resetting to zero.
