A gearing for converting a constant rotation of its drive shaft to an intermittent rotation of its driven shaft, in which the driven shaft may be stopped and positively locked during each complete revolution of the drive shaft for any predetermined period which may last from a momentary stop to one amounting to a considerable angular distance of each revolution of the drive shaft. The transition from the stopped position to the normal speed of the driven shaft occurs very gradual and without jerks, the locking action upon the driven shaft is attained without any additional locking means, and the entire gearing is of a very simple and inexpensive construction. |
