Iii the drawings 1, is a turbineengine resting'en the bed '2 and provided with a shaft 3, to" which shaft is secured any-"desirable piston 4 having vanes 5. Rings of stationary vanes 6 are secured to the shell of the engine. The front end oflthe shaft is journaled in a frame 7 and has a'worm 8 secured to it, which worm engages the worm wheel 9 on the shaft 10. This worm wheel and shaft are mounted in the casing 11. ,On the shaft 10, at right angles to each other, are the 'cranks 12, to each of which is connected a connecting rod 13, the lower end of each of which connects to a piston l i-of a com ression cylinder 15. The inlet port 16 0 the I cylinder communicates with a carbureter 17 by means of a connection 18, at the upper soon as the engine is in operation.

A pipe 32 connects to the bottom end of thisvalve chamber and to thespaces abovethe piston 27 in the cylinder 26. A resilient .1 ceives the valve 30 whenitisforceddown. Apassa'ge 35 connects the pipe36-withthe-I passage 37 whenever the, va.lve permits:

p The operation of this::mechanism-isas. follows: After the enginezhasbeen put in 176' operation by means :of ompressed air in the tank 22,2111 upward stroke of-thepiston,

.14 will draw an explosive mixture from the; carbureter 17 into the cylinder 15'. ,The pres-- 3 sure of the air in the tank 22 will: be cominunicated throughthe i -e525 and :32 to the lower side of the valve30' and hold it-in [place The. down stroke of thepiston-l t will compress the charge whichfis exploded by means ,of the spark-plug. 20as-soon as compressed. The force of .the explosion will drive down "the valve 30: permitting the burned gases to rush downlthe' passage-37, through the passage 35 and-up 'the passage 1 .36 into the engine, driving-the same. Atthe-'85 same time a part of the gas will push up the piston 27 against the pressure in the tank. The valve 30 being ofl its seat so' long as the pressure in the cylinder 15 exceeds that in the tank, the gases in the cylinder 26 will flow back through the passage 16 and down the passage 37 as soon as the pressure in the cylinder 15 diminishes When the pressure of-the burned gases onthe upper side ofthe valve 30, plus the weight of this valve, is less than the pressure on the lower side of this valve, the valve will be forced to its seat.

It will be noticed that this compressor will have an explosion whenever the piston reaches the bottom of its stroke. With two compression cylinders and pistons, there will be two explosions at each revolution of the Any desirable valve may be substitutedfor that ,betweenthe com ressor and'engineand the carbureter emp oyed will depend upon'the selection of the constructing engi neer.

Many of the details may be varied without departing from the spirit of my invention;

Having now explained my improvements, what L claim as my invention and desire to secure by Letters Patent is 1. In an explosion engine, the combination of a motor and the shaft thereof, a crank shaft actuated by the motor shaft, compressors driven by said crank-shaft, a discharge valve for each compressor, a pipe leading from each 'valve to said motor, a source of supply of explosive vapor, and a pressure equalizing device for said compressor comprising a chamber and'a resiliently held piston'therein.

'2. In an explosion engine, the combination of a turbine engine having a shaft, a worm on said shaft, a crank shaft, a worm wheel mounted thereon to engage the worm on-the turbine-shaft, a crank on each end of the crank shaft, "two conipressicn cylinders and pistons therefor, a connecting rod between each piston and its crank, an equalizingcylinder connected to each compression cylin return'the piston in the equalizing cylinder.

4. In an explosion engine, the combination of an explosion motor, a compressor for fuel vapors, niechani'sm for driving said com pressor by the motor, an equalizing chamber connected at its lower end to the compressor,

a piston in said chamber, an air compressor, 7

and a pipe connecting the upper end of said equalizing chamber and said air compressor.

5. In an explosion engine, the combination of a turbine, a compressor driven thereby, a discharge valve for said compressor comprising a cylinder and a piston therein, an air compressor, and a pipe connecting the air compressor and valve cylinder so the compressed air will normally hold the valve on its seat.

6. In an explosion engine, the combination of a turbine, a fiiel compressor driven thereby, an equalizing chamber connected at its lowerend to the compressor, a piston in said equalizing chamber, an air compressor, a pipe connecting the upper end of the equalizing chamber and the air compressor, a discharge valve between the fuel compressor and the turbine, and a air compressor to the va ve chamber.

7. Thecombination of an en ine having a shaft, fuel compression cylin ers adjacent thereto, compressing pistons in said cylinders driven by said shaft, means to supply explosive vapors to said cylinders, an air compressor and a receiver, a piston discharge valve at the bottom of each cylinder, a pipe extending from each valve to the engine, means for supplying explosive vapor to the compression chambers, an air compressor and pipes connecting the air compressor and the discharge valve to convey air under pressure whereby the valves are normally held on their seats.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
