ABSTRACT:
The present invention provides apparatus for changing the direction of rotation of a rotating shaft without changing the direction of rotation of the motor driving the shaft. The present invention includes a drive gear which causes two driven bevel gears to rotate in opposite directions. A control shaft having cam surfaces selectively forces one of two sets of balls into engagement with one of the driven gears to couple that gear with the driven shaft to rotate the shaft in one direction. Rotation of the driven shaft is reversed by changing the position of the control shaft which uncouples one set of balls from the driven shaft and couples the remaining set of balls to the driven shaft.
