FRED SCHMIDT, OF OHICAGD, ILLINOIS, ASSIGNOR, BY DIRECT AND MESNE ASSIGN- MENTS, 'IO MAJOR ENGINEERING CORFORATION, A CORPORATION, OF ILLINOIS.

INTERNAL-COMBUSTIN ENGINE.

Application mea Mai-'h 17, 1921. serial Np. 453,109.

To all whom 'it may concern- Be it known that I, FRED SCHMIDT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use-` ful Improvements in Intsmal-Combustion1 Engines, of which the following is a specitication.

The invention relates to improvements in internal combustion engines oiE the turbine type and associated air compressors.

An object is to provide a turbine engine having a rotor arranged to be driven by impact of the exploding charges projected from a contiguous combustion chamber.

Another object is to provide a structure having a combustion chamber in which an explosion takes place and in which the valve is automatically opened by the effect of the explosion to permit the products of combustion to be projected against the peripheral surfaces of an associated rotor.

Another object is to provide, in an engine of the character described, a casing containing a combustion chamber having an admis-k sion` valve which automatically opens as a result of the pressure of the charge to admit the charge into the combustion chamber and another valve that automatically opens by the eii'ect produced by the explosion, to permit the products of combustion to strike the peripheral surfaces of the rotor at suitable intervals to drive the same.

Another object is to provide means for introducing steam or vapor into the eX- ploded charge after it leaves the combustion `chamber and before it strikes the rotor.

Other, further and more specific objects of the invention will become readily apparent, to persons skilled in the art, from a consideration of the accompanying drawings, wherein z- I `ig. 1 shows a central sectional view of one of the large casings, or bottles, containing a combustion chamber, within which the explosions occur. K

Fig. 2 is a section taken on l1ne2-2 of Fig. l.

In all the views the same reference characters are employed to indicate similar parts.

I The casing is provided with a lange 82, having holes 83 thru which cap screws Bet may be inserted to secure the casing to the fraise of the engine The Casing 0r bottle 75 is provided with a head 85 screw threaded as at 86 for insertion in the end of the casing. The. head Sois also provided v for a piston head S9 `which is the terminal end of the tube 87 and the head S9 moves. freely inthe bore 88. The valve is held closed by an open helical spring 91, the strength of which may beadjusted by thc screw plug 94A. f

The piston 89, of the valve 79, is larger than the tubular portion 90 of the valve, and at intervals around the bore 88 are a series of perforations `or holes 93 openingV romthe interiorof the bore to the interior or the bottle or the combustion chamber 76.

A spark plug 92, threaded into the casing 7 5, near the port 78 thru which the products of combustion are discharged upon the occasion of an explosion of the combustion provided with terminals 9 5. The casing 75 is provided with a hub 96'which is internally screw threaded, as at 97 and into which a plug 98 is screwed carrying a check valve 99, normally closed by the spring 100.

The fuel charges consisting of the proper admixture of air and suitable quantity of gasoline vapor comes thru the pipe 101 from the compressors and is delivered into the combustion chamber 7 6 by thev self-opening puppet valve 99.

The spring 100 is set so that when the pres sure of the charge to be injected into the combustion chamber 7 6 is suliicient to overcome the resistance ofthe spring, the chamber is filledwith an explosive mixture under pressure. Just at the time when the pressure is at maximum value a spark is produced at the terminals 95 of the spark plug 92, whereupon an explosion will take place in the chamber 7 6. The eect of the explosion is to open the valve 79 by the pressure applied to the piston 89 oit the valve 79 thru the openings 93. Immediately upon the opening of the valve 79, the products of combustion will pass out with considerable force, thru the nozzle 89, and iinpinge upon the cups of the rotor, thereby causing the rotor to revolve at high velocity. Y

A Water supply pipe 102 leads from a suitable ysource of supply and connected to the valve 103 which may beopened, to a greater orless extent, by rotating'the handle (itt chamber, is screwed into the casing and is and at high velocity, it produces a vacuum eect in the tube 90 of thevalvefQ `and causes Water tobe drawn into the tube Which is converted into steam" bythe hot lsurfaces of thetube 90 and lwhich goes out Withthe f next-charge that leaves the combustion chamber 76. '.'By this means Wateror steam which is more ponderable than the gases ofexplosion is carried with 'forcible effect-"against the peripheral surface of the .rotor.

The power thus producedis much :greater than -it'otherwise Vwould *be Wit-houtthe lassistance of "thewvaten The Water furthermore has the effect of keeping thecombustion-casing frelatively cool so as to prevent spontaneousl explosion. "While the" engine Will-*run Withffair eliciency Without the Water `for a protracted period of time Without dangerous heating, it `is believed that the Water 'contributes tojproduce a higher efiiclency, its expansion vinto steam contributl'ingto the force of the impact.

I-Iavilrg described 'my invention VWhat-'I claim .as tnew and Adesirento secure by'l Letters Patent, is:-

lA vernnbu-'stion chamber agnd nozzle for turbinegas engines comprising a b0ttle-like Within the casing and' a' pipe Within the tubular valve, whereby tofintro'duce Water therein by the suction 'effect 'produced -by the heated gases thru saidfport.

Y In `testimony 'whereof I `hereunto "subscribed Amy name. Y
