In presenting this engine tonho public, apeclnl nttention la directed to the entirely new design nnd compact form of ita con¬ struction, mnklng It the most dcslrablo en¬ gine known for the viirlona offices tluit the Kteain engine la culled upon to lullfll. It hns ao ninny points ul excellence thnt me appar- ent, thut it will only be necessary to enum¬ erate n few of the funny ndvnntngoa secured by thla valuable improvement, and we have endeavored to confine ourselves to no more than the actual space required for such In¬ formation. As tho engine hn> no dead cen¬ ter, It can be started with 'lio ouiiik In .mv position. Tho connecting rods being always In compression, tin re Is no sudden blow or pound1 upon the crank-pin, liowover loose tho fit may be, with the engine imining at any speed. The uoiking-parts hi Ing en¬ tirely encased, they are pioleeted and kept free from any dust or grit that inuy bo -aground tlmongln The details ol constluclIon ale tho renult of long experiment and caielul sludj', com¬ bined with prncllie. The pistons being deep, Ifojlit, and well packed, guldu themselves hi Uie cylinders, and are connected to steel connecting lods, the ends-of- w-liluli toun-tlie-cuuueccioiia_ia_ tbe crank pin. On the end off each rod Is a compensating box, which, in/ ease oi wear, can be re¬ placed milking the connection as good as new. Tlili arrangement admits oi the en¬ gine automatically taking up her owr wear, hb the thrust Is always on the crank pin. The moment the steam is admitted to the piston, which la always at (he beat leverage roda, which are very accessible, the packing cups being deep, so that when once packed, a slight turn of the gland la all that Is hec- oisnrj,should any steam leak through them; the front ahd buck bearings of the shaft being only puckuil against exhaust steam. Its form Is unique; nil angles and corners being nvoidedjuid everything belugclrenlnr, adds materially to Its strength, juid If re¬ quires le»B room and weighs less than any engine known ol the same power Every part is Vccesaible, and the engllio cull lie stripped mill nut togithcr again In less time than the oidlnnry engine 'I he lirculnr ring or belt, of which the cjlindeis form n part, also forms the'valve stats, audit will b6ob¬ served, that the vahes and seats arc at close to the cylinders ns Ik possible.

The valves nro the ordinary slide, very much Improved. Ench one is scraped to a perfect tit, and they are absolutely tight against leaknge of steam. J be valve motion Is tho most simple over produced, ono e( centric. In one revnlvtion, completes the travel of tho three valves. The pistons will follow up their connec¬ tion until worn out. All the working parts of thla engine are made of the phosphor- bronze and Bteel. The crank shaft Is counterbalanced so as to Insure #U ally running while the engine Is at work, ami extends through boxes In tho pedestal,which lias a long bearing on the pul¬ ley out), ao na to reduce the wear to the minimum. On the front end of the shaft la a cut gear-wheel, to connect with the gov ernbr gear, making the governor a part of the engine Itself, thereby ensuring n per¬ fectly uniform motion to the engine. As the governor goes, so must the engine. There are no belts to break or parts to glvu way (which often cause burl accidents), so that the governing powor Is as porfeig/and con¬ stant as can be devised. All parts of the governor are accessible, and the spued of the engine can bo changed Instantly, while It Is running, to any extent desired, within the rjinge of the governor. .
