Modern mechanism, exhibiting the latest progress in machines, motors, and the transmission of power, being a supplementary volume to Appletons' cyclopaedia of applied mechanics . rom which small single rods extend to the releasingmechanism of the four cylinders, doing away withtlie use of the double rods usually employed, incompouufl engines tlie coiniectmg rods arc six ttranksin leni^th. The piston-rods have two dilfcrcnt diam-eters in their length, the difference being sullicieni toafToni a taper seat for I he low-pressure pistons. Thesejiistons arc held in filace l)y a key. By disconnecting tlie rod at the cross-head and movingthe low-[)nssure piston back into the space between the two cylinders the key can be removed :then, by movini; the rod forward, the |)iston can lie removed. A notiiu-ahle feature in tiicseengines is the fastenings which hold the biNl-plales to the pillow-block. In addition to theusual bolts, recesses an- cast in the front sidi <if liic pillow idock and in the front side of theframe against the pillow-block, and a wrought-iron link is shrunk over the parts bythe recesses, binding the pillow-block and frame firmly Fig E^GIXES, STEAM, STATIONARY RECIPROCATING. 325
