The piston on thevalve stem has a larger area than the valve disk. The valve is held open by the relief from pressurethrough the by-pass and three-way cock. The dropping of itslever by a lanyard, closes the re-lief and gives the rear side ofthe piston the full steam pres-sure, quickly closing the by-pass valve at the top isfor equahzing the pressure andallowing the valve to open bymeans of the relief at the three-way ^^3 lOO STEAM POWER APPLIANCES. 232. REVERSING GEAR for a steam engine. The figures showa side elevation of the reversible eccentric, with handwheel for oper-ating it, a front elevation show-ing the engine shaft in crosssection, and a perspective viewillustrating the application ofthe invention to an upright en-gine. The eccentric is formedwith a hub having shoulders toengage a stop pin on the shaft,in combination with an operatingwheel placed on the hub of theeccentric, and having a limitedrotary motion thereon. Theeccentric has a hmited inde-pendent motion upon the shaft,and the handwheel has a ro-tary motion independent of the eccentric, combined with spri
