摘要

A clutch device for transmitting rotation movement from a flywheel to a shaft of a mechanical press, comprising a drive member received for sliding movement along a groove in the shaft surface, a stop bar mounted for movement between a first locking position, in which the stop bar is applied to the driving member to maintain the same in a retracted position separated from the steering wheel, and a second released position, in which the driving member is urged by elastic means until an operant position, in which operating position the drag member is applied to the flywheel to transmit rotational movement of the flywheel to the shaft, and means for driving the stopbar, characterized in that a first cam is provided to attack the drag member during a unique revolution of the shaft to cause the drive member to retract progressively from the operative position, and that a second cam, mounted to rotate with the shaft, is provided to engage the stop bar during a single revolution of the shaft, to cause the stop bar to move from the second position to the first position, the cams being arranged first and second such that, upon completion of one revolution of the shaft, the stop bar is in the first position and the driving member is attacked by the stop bar in the retracted position.
