Abstract
A gearbox has a partly toothed drive gear wheel with a toothed segment and a toothless segment on its circular peripheral surface. A driven gear is completely toothed and meshes with the toothed segment of the drive gear when it is presented to a mesh point between the gears. Pawls on the gear shafts synchronize the initiation of the mesh. The number of teeth on the drive gear is selected so that 360 degrees of rotation of the drive gear results in 360 degrees of rotation of the driven gear. As the drive gear toothless segment just reaches the mesh point, a brake on the driven gear shaft is actuated to accurately stop the motion of the driven gear shaft. The driven gear shaft is thereby halted while the drive gear is free to turn until its teeth once again reach the mesh point.
