ELASTIC-FLUID QIOTOR.

To all whom it may co'nccm:

spend therein.

Be it known that I, CHRISTOPHER J HN (formerly JOHN (ntusrornnn LAKE),

LAKE a citizen of the U nited States, and resident unty of Fairfield and of Bridgeport, in the co State of Connecticut, have invented certain new and useful Improvements in Elastic- Fluid Motors, of which the following is a specification.

This is a divisional application pertaining to subject-matter sho my former application filed J anuary 4, 1906, Serial Number 294,552, and'which was divided out of the claims in said former application pursuant to a requifement'of division in Ollice letter of October 6, 1906.

"The present invention consists in certain new and useful improvements in elastic fluid motors for the conversion of the kinetic en ergy of power fluids into useful mechanical power.

The object of m invention is to produce a rotary engine in w rich the power fluid will be distributed over the largest number of impact surfaces at the maximum volume and velocity constantly maintained throu 'hout the engi11e-ei1cuit, an(l therefore, with the highest efficiency.

A further object is to produce an engine in which the direction of rotation may be readily reversed and which will operate at its highestefiiciency in either direction.

A further object is to produce an engine in which water or other liquid condensed therein will be constantly. and automatically removed without any escape of the powerfiuid.

V-fith these objects in view and further objects which will appear as the nature of my invention'is more fully set forth, I have produced an engine that embodies one form of my invention as hereinafter described by reference to the annexed drawings, in which:

Figure shows an external end view of my improved engine in connection with a power fluid generator which I have described and claimed in said formerapplication. is an end sectional view through the engine casing showing an end .view of the wheel Fig. 3 is a side elevation of the wheel of my engine removed. from the casing.

The gate 69 and the link 71 are duplicated on the opposite side of t nected in such manner he block 72 and conthat the inlet and exhaust pipes res ectively will communicate tangentially wit i either side of the wheel according to the position of the block 72 which is shif table by means of lever 73 and link 74, shown in Fig. 1, for moving it along the periphery of the wheel to pipe.

It will be readily seen moved to the right hand side that wihen the block is of the inlet pipe, all the conditions will be reversed and the wheel will rotate in tion.

The arrangement of in exhaust conduit 68 around my inlet conduit n2 is also an important feature of my invention. 'lhis arrangement allows-the power lluid to act upon a given unit of impact surface of the wheel through nearly an entire revolution before coming to the point of exhaust. 'ihis late exhaust is especially desirable in connection with my special l'ortn ol' wheel in which nearly the. entire grow-ed peripheral portion is constantly and continumislv under the iniluence ot' the power lluid. My arrangement of the exhaust passage around the inlet has also the further advantage of providing a convenient exhaust opening from either side of the wheel without du lication of pipes for that purpose, and it a so prevents excessive radiation from the inlet pipe. and consequent loss of power.

The pipes 76 areplaced in the casing 64 to provide an outlet for any condensation that may collect in the bottom of the casing. These pipes are bent into a U shape and kept filled with liquid whichpreventses apeol' the gaseous power lluid l'rom the. casing. The pipes placed inopposite sides of the casing at about its mid-height so that one of them will carry of? the liquid in the. exhaust side of the.wheel in whatever direction it may be. running. These passages may be. omitted in any case where it is desirable to invert the. engine or where the power fluid is such that condensation is not met with.
