A device for interconverting rectilinear and rotary motion is designed so as to reduce side thrust exerted on a frame by a slide as the slide reciprocates linearly relative to the frame and such rectilinear motion is converted into the rotary motion of a crank or vice versa. More particularly, an elongated opening, which receives a crankpin of the crank such that the crankpin moves back and forth along the elongated opening, is provided in a swing mounted for oscillatory movement relative to the slide. At least one arm is pivotally attached to the frame and to the swing so as to effect the oscillatory motion of the swing relative to the slide as the slide reciprocates relative to the frame. As the slide reciprocates relative to the frame, the orientation of the elongated opening relative to the slide is constantly varied. |
