of which it receives and communicates reciprocating motion, as in the valve gear of some steam engines; -- called also rocker, rocking shaft, and way shaft.

esembling, the motion of a wheel on its axis; rotatory; as, rotary motion. Rotary engine, steam engine in which the continuous rotation of the shaft is produced by the direct action of the steam upon rotating devices which serve as pistons, instead of being derived from a reciprocating motion, as in the ordinary engine…

he sun must cause an equatorial rise of the solar atmosphere. Siemens. Rotative engine, a steam engine in which the reciprocating motion of the piston is transformed into a continuous rotary motion, as by means of a connecting rod, a working beam and crank, or an oscillating cylinder.

It usually consists of a box or chamber, made by an enlargement of part of the hole, forming a space around the rod or shaft for containing…

genious contrivance for converting reciprocating motion, as that of the working beam of a steam engine, into rotatory motion. It consists of a toothed wheel (called the sun wheel), firmly secured to the shaft it is desired to drive, and another wheel (called the planet wheel) secured to the end of a connecting rod. By…
