ABSTRACT:
There is disclosed a precision drive mechanism having a base member with a drive plate slidably connected thereto, the drive plate having an elongated slot engaged by a bearing member, which in turn is threadably coupled to a lead screw. A pivot frame having an elongated arm is pivotally connected to the base member and is slidably engaged by the bearing member, the pivot frame being adapted to be connected to a source of fixed reciprocating motion whereby the drive plate is moved by the pivot frame in variable reciprocating motion precisely adjusted by moving the bearing member along the elongated arm of the pivot frame through rotation of the lead screw.
