Crank and slotted lever quick return motion mechanism:
1 Fundamentals and type of mechanisms (17412)
Define completely constrained motion and successfully constrained motion with neat sketch. State one example of each.
Each part of a machine, which moves relative to some other part, is known as a kinematic link.
When the kinematic pairs are coupled in such a way that the last link is joined to the first link to transmit definite motion (i.e. completely or successfully constrained motion), it is called a kinematic chain.

1.Reciprocating engine, Reciprocating compressor;
2. Whitworth quick return mechanism, Rotary engine,
3.Slotted crank mechanism, Oscillatory engine.
4.Hand pump, pendulum pump.
1.Reciprocating engine, Reciprocating compressor link 1 is fixed
