ABSTRACT:
A one revolution clutch assembly is provided which transmits the rotation of a normally rotating drive shaft to a driven rotating body through gears and which interrupts the rotation of the driven body when it has rotated through one revolution. The one revolution clutch assembly includes a drive gear mounted on the drive shaft and which meshes with a driven gear on the driven body. The driven gear is formed with a hiatus along part of its periphery, and when the hiatus is located opposite to the drive gear, the rotation of the driven gear is interrupted. The driven gear is maintained in this position where it ceases to rotate, by a cam mounted on the driven assembly and formed with a notch which is engaged by a movable piece of an electromagnetic plunger. A crank lever has its one end rotatably mounted on the driven assembly, and imparts a rotating force to the driven gear to cause a meshing engagement of the driven gear with the drive gear when the driven gear is located at said position. When the plunger is actuated to release the driven gear, the crank lever causes a rotation of the driven gear. The timing when a meshing engagement between the driven gear and the drive gear is initiated is determined by a projection on a cam follower which is provided on the driven assembly and which engages a notch in a cam provided on the drive assembly.
