The pistons are driven by cams on the driving shaft . The driving shaft is driven via a means of a roller ratchet assembly which converts the reciprocating motion of the operating linkage to rotary motion.

In the Industrial Revolution, James Watt contributed to the development of the flywheel in the steam engine, and his contemporary James Pickard used a flywheel combined with a crank to transform reciprocating motion into rotary motion.
33.
The reciprocating motion is achieved by using two claws to pull the round from the belt, and then an arm pushes the round into the cartridge guide ready for the bolt to carry it to the breech.
34.
The first effect of starting the machine is to cause the colour sieves, which have a reciprocating motion, to pass over, and receive a charge of colour from, the rollers, fixed to revolve, in the colour troughs.
35.
A "'quick return mechanism "'is an apparatus that converts circular motion ( rotating motion following a circular path ) into reciprocating motion ( repetitive back-and-forth linear motion ) in shaping machines, which are utilized to shape stocks of metal into flat surfaces, throughout mechanical engineering.
36.
"' Magnetorheological abrasive honing "'( MRAH ) is a recently developed process that makes use of magnetically stiffened abrasive-mixed magnetorheological fluid and combined rotary and reciprocating motions to finish engineering surfaces . Magneto-rheological abrasive finishing is a non-traditional method of improving the surface finish of manufactured components.
37.
While the side rods ( UK : coupling rods ) of a locomotive can be completely balanced by weights on the driving wheels since their motion is completely rotational, the reciprocating motions of the pistons, piston rods, main rods and valve gear cannot be balanced in this way.
38.
An early known example of rotary to reciprocating motion can be found in a number of Roman saw mills ( dating to the 3rd to 6th century AD ) in which a crank and connecting rod mechanism converted the rotary motion of the waterwheel into the linear movement of the saw blades.
39.
In order to do so an eccentric usually has a groove at its circumference around which is closely fitted a circular collar ( " eccentric strap " ) attached to which an " eccentric rod " is suspended in such a way that its other end can impart the required reciprocating motion.
40.
French Army Captain Cugnot was one of the first to successfully employ a device for converting the reciprocating motion of a steam piston into a rotary motion by means of a dray " ) was made and used in 1769 ( a " fardier " was a massively built two-wheeled horse-drawn cart for transporting very heavy equipment, such as cannon barrels ).
