Description
Lever 1 rotates about fixed axis A and is connected by turning pair B to pinion 5 which is rigidly attached to gear 4. Gear 4 meshes with gear 3 which rotates about axis A. Pin b of pinion 5 slides along slot a and provides for engagement of pinion 5 with complex internal rack c which consists of two straight and two semicircular portions. Rack c belongs to slider 2 which reciprocates in fixed guides d-d. When driving gear 3 rotates continuously at uniform velocity, pinion 5 rotates about axis B, imparting reciprocating motion to driven slider 2 at uniform velocity during the periods that pin b slides along the straight portions of slot a. When pin b slides along the semicircular portions, lever 1 turns about axis A and slide 2 has nonuniform velocity. $2406$LrG,4L$
