Abstract

Device for automatically taking up the play in a braking mechanism comprising a cylindrical piece (30) rotatably movable about its own axis (x--x'), of which the rotation over a fraction of a revolution is ensured by a control member (41) able to pivot alternatively in one direction and the other, its pivoting taking up the play. The control member acts on said cylindrical piece by the intermediary of a spring-wire (38) rolled around the latter, in such a fashion that when it presses the spring-wire in one direction it engenders its tightening on the cylindrical piece and correspondingly the driving of the latter by friction, while in the other direction it engenders the release of the spring-wire and correspondingly its disengagement with respect to the cylindrical piece, the latter not being driven.
