Introduction :

When one of the links is fixed in a kinematic chain, it is called a mechanism. Thus, we can obtain as many mechanisms as the number of links in a kinematic chain, fixing, in turn, different links in a kinematic chain.

This method of obtaining different mechanisms by fixing different links in a kinematic chain is known as mechanism inversion.

Single slider crank chain mechanism

A single slider crank chain is a modification of the basic four-bar chain. It consists of a sliding pair and three rotating pairs. It is usually found in reciprocating mechanisms of steam engines. This type of mechanism converts rotary motion into reciprocating motion and vice versa.

Oscillating cylinder engine.

The mechanism arrangement of the oscillating cylinder engine is used to convert the reciprocating motion into rotary motion. In this mechanism, link3 forming the rotating pair is fixed. Link 3 corresponds to the connecting rod of a steam engine reciprocating mechanism. When the crank ( link2 ) rotates, the piston attached to the piston rod ( link1) reciprocates and the cylinder (link4. ) oscillates around a pivot pin in the fixed link at A.

Oscillating cylinder steam engines are now mainly used in toys and models, but in the past they were used in full-size working engines, mainly ships and small stationary engines. They have the advantage of simplicity and, therefore, low manufacturing cost. They also tend to be more compact than other types of cylinders of the same capacity, which makes them advantageous for use on ships.
