ABSTRACT:
An incremental drive for the incremental driving of a rotary shaft or of a line device, having a rotary driver shaft adapted to be driven by a power means. A plurality of cams are mounted on the drive shaft each having an offset camming surface relative to the axis of rotation of the driver shaft. A shoe with a respective engagement face is fitted to a respective cam. A driven element--rotary or linear--is sequentially contacted by the engagement faces. The driver shaft is resiliently biased toward the driven element. Rotation of the driver shaft causes the shoes sequentially to drive the driven element, and the resilient bias maintains driving contact and enables relief of the shoes from the driven element during operation.
