Description
Link 1 is designed as a round eccentric rotating about fixed axis B. Link 2 has collar a encircling eccentric 1. Collar a has cam surface b of special shape along which roller c of link 3 rolls. Link 3 oscillates about fixed axis D. Bent lever 4 is fixed during operation and rotation of eccentric 1 is transmitted through link 2 to link 3 with roller c. Motion of link 3 is regulated by turning lever 4 about fixed axis A and clamping it. This changes the law of motion of link 3. $1694$LC,5L$
