Abstract

Two pushers are connected to the oscillating source via a rectangular frame and are mounted coplanar with a ratchet wheel so that they lie on opposite sides of the wheel centre. The ratchet wheel has an odd number of teeth with radial driven faces. The driven face is pushed, and the wheel rotated, until the pusher lies against the back of the next tooth. The wheel then acts as a limiting stop and prevents further motion in the direction. The source reverses and the other pusher indexes the wheel by one tooth. A spring-loaded friction pad bears onto the ratchet wheel shaft.
