A linear motion mechanism is disclosed consisting of an output member comprising a slide block mounted for sliding linear movement on a slide frame, which slide frame is in turn detachably secured to a vertical drive assembly including a mounting frame having a vertically extending mounting surface formed thereon. The slide block is drivingly connected to a motion amplifying mechanism carried on the mounting frame including an input push link on which is rotatably mounted a rotary drive element engaged with a drive chain fixed at one end and connected at the other end to the slide block so that the motion of the slide block is an amplification of the motion of the push link in direction away from the chain ends. The push link is translated by a rotary cam and pivoted lever pinned to one end of the push link. The slide block and slide frame are adapted for use separately from the mounting frame and motion amplification mechanism by mounting it on a horizontal surface and directly engaging the slide block with a rotary cam. |
