To all when: it new concern:

Be it known thnt i, it I. TICANllF-TR ll. l lDVr'MllJE-Q ll. citimen of the United States, n ling in; Long-hutch, in the county of Lon rlngeles znnl finite oi tnlil'ornin, have in.- vented new and usel'nl lilllliUVOlllClllzl in .ltotory l 1-- gines, of which the following is n s ilii'rntion.

An Ubjoot ol my invention is to p1,Vi(lD means WlltllU by steam or other Agency employed in rotary engines is admitted at both ends of the rotary piston huh, and thereby equalize the pr we fill either ornl thereof.

Another ohjectis: to pn Lflt: on inljnslwtlill: cut oil for the inlet ports oi the engine.

Another o bjoct is to provide it re large power for the size thereof.

Live steam ismhnitted into the engine through the inlet ipe 13 which passes thenee into the annular groove 14 lsee Fig. 1) in the end plate. -This annular inlet groove extends (H'Ollllil on the inside of the end plate nearly the entire distance it] ill is provided with an adjustable out ell 15 (see Fig. at), which has on air tight lit therein and is holdtightl in its adjusted position by the set screws THE.- lrleginentztl openi s l7 (Fig.1.)are provided in tlleeml plates lo? the pat thorethrongh ol the shnnlasoi the screw-1 In, providing thereby means for the adjustment of the cut oil 15 at any desired position in the inlet groove l li Both eml plates nreprovidcd with these annular grooves, and.

Having described my invention what l claim as new and desire to secure by .liettors Patent is:--

1. In a rotary engine, the combination of a. piston cylinder and on abutment cylinder, said piston cylinder previilod with n piston bltti exhaust grooves and inlet ports, said. abutment cylinder being provided with a recess; end plntes having: linnnlur inlet grooves in their faces and an exhaust port; and o, steam cut oil ntljustably mounted in the inlet grooves;

1n 1m ermine or. the character described, :i rotary lllslen cylinder carrying ii piston hlnxle and bovine in one]! end thereof on exlnn l port cormnuni V n; on allotment eyilnder havingon the periphery thereof :1 piston blade wing recess, the said cylinders worknbly (minim-ted by spur gears, in combination with a casing snrronndint, said cylinders :nul having it each end thereof adjnceotto the piston cylinder an annular inlet groove, the snltl piston cylinder having on either 92111 thereof on inlet port communicating with the inlet groove; :1 shut off'adjustably secured in the inlet groove, substantially as herein shown and described 3. In :1 rotary engine 01 the character described, a piston cylinder carrying a piston blade the entire length thereof and having in each end thereof an exhaust groove communicating with an exhaust port, the said cylinderhcing provided atcuch end with an exhaust port in ad- VI-ZUCE 01 the piston blades and provided at each end in the rear of the piston blades with inlet ports, in combjnw tion with a casing having in each end thereof an annular inlet groove; and 9. check adjustahly secured in the inlet groove.

In witness that I claim the foregoing I have hereunto subscribed my name this 16th day of February, 1907.
