To all whom itmm/ concern;

The invention for which this is an appli-- cation for Letters Patent, consists in improvements in internal combustion motors, driven by turbine action, in which the high temperature, produced by the combustion of the gases, is lowered and kept at a sim lar temperature to that' of the steam, by using steam, produced by the motor itself and the same steam will be used as a power tor dr1ving'the turbine with the gases.

The primaryobject of my invention is to provide a turbine with one or several sets of rings of moving blades, and fixed blades, one next to another; one or several combustion chambers secured to a plate with nozzles for the gases and for the steam; and two compressors, one for compressing the air and the other for generating the gases. The compressors can be driven by the same or by different motors. p

The' same letters and numbers-in these specifications, apply to the same letters andnumbers in the accompanying drawings.

The worm gear E, is secured to the crank shaft F, to which is fixed the bevel gear G, which engages the bevel gear H. The bevel gearH, is secured to the pin J, to which is fixed the gear I, intermeshing with the gear K, secured to the drum L, which turns on the sleeve M. of the shaft C. One end of the sleeve M, is bolted to the plate N, and the opposite end is kept rigid by the braces 0,

which are bolted to the frame. On the drum L, is secured the cam wheel 1 to this wheel are attached two cams Q and R, and two pins S and T. The cam,Q on the circumference engages the rollers 1 of the lever V, and V; the cam R fixed on the plane side of the wheel P engages the levers U; the pin S, inserted on the side of'the wheel right below the circumference engages the levers X; the pin T, which is longer and farther from the circumference, engages the levers Y and Y.

Qt the two cranks of the crank shaft F one drives the pump for the air compressor a, and the other drives the two pumps for the gas generator 6. 'Theair compressor can be built by using some pattern already in the market, provided thiswill .be of the capacity suitable for the motor. The compressor can compress the air in the explosion chamber directly or as it is done in the ac companying drawing, the air is compressed in the accumulator c, and from the accumulator is discharged into the circular tube (Z, and from. the circular tube into pipes e, and from the pipes into combustion chamber 7. The flow of the air is shut off from the combustion chamber by the valve 9 operated by lever Y. The motor of the accompanying drawing has five combustion chambers, and as the five combustion chambers are provided with the same valves and the same machinery for their operation the description of one applies to the others.

The other crank sets in action the double pump it, for generating the gas (Fig. 6). The piston it, in its outward movement sucks the air through the valve 7', at the same time that the piston 2', in its outward'movement sucks the oil through the valve Z. .On their return the piston 2', willforce the oil through the valve m, into the chamber a, and the piston 7t, forces the air through the valve 0, and causes it to enter into the chamber a, at the same time as the oil; the air by mixing with the oil will volatilize the oil, thus transforming the oil into gas. The continuing inward movement of the piston will increase the pressure of the gas in the chamber 12, the gas will force its way through, the valve 7), into accumulator 9 (Fig. 3) and from the accumulator into the circular tube 1", and from this tube into the pipes s, and from the pipes s, by opening the valves (7 operated by levers Y, will enter the combustion it Specification of LettersEatent.

v The i rior of each combustion chant ber f elongated cone ""ig in. a nozzle cu, in the term of a i *mel (l ig.

At the point or unction ot the nozzle with the combustion chamber, which is the hair-- roivestpart of the two, there is a casing tor the valve 7 This valve in lowest part is composed @i' a flat solid piece of iietal 3 Wide and. long enough to close the neck of the combustion chamberl) above the neck. the valve is perforated by circular hole to, of the same diameter as the opening that connects the combustion chamber with the nozzle. This valve is pivoted by the rod El, to tl e lever 3. 0n the other end of this lever is pivoted the rod il oi the pi to'n5. This piston works in the chamber 6, which opens into the interior of the combustion chamber. At the moment the esp lo sion of the in the combustion chamber, the pressure of the gases force the piston 5 up by compressing the spring inverted on the rod t. By this'cpcraticn the lever 3 forces down. the circular open lg 10, of the valve y, and by so doing opens the communication. between the combustion chamber and the nozzle. As soon as the gases have left the combustion chamber the spring 7 forces the valve to its normal position.

The hole 8, which puts into communication the interior oi the combustion chamber with the atmosphere is opened and closed by a valve 8 operated by the lever U (Fi This valve is opened mechanically by the engagement of the lever ll "With the cam propeiuv timed after the explosion to permit the scavenging of the vitiatec. gascs Simultanecusly withthe engagement ot the cam ll and the lever ll, segment Q, engages the roller 1 of the lever Y to displace the lever V and open the valve 9 thereby admitting air from pipe'e into the combustion chamber to effect the scavenging, the vitiate'd gases passing from the chamber through the valve 8 as described. More detailed explanation of the operation. of the valve g is had from the f llowing description. The compressed gases are admitted by the vlavewhich is opened "y the lever V and closed by Y. The .f ls which enter into the construction of rose valves are the same for both and their may of Working is the same also; so ll will describe one and the description of this will e of ietal other hal' perforated by iolc ll. diameterof the hole is equal to that of pipe c. A stein is bolted below the sol part 10, which has a cas ng in form of a "l. lln this casing insererl the upper part the lever l this lever has its fulcrum on the pin'ld, and in its lower end carries the Wheel 1 which, when it str kes the segment ll, coinpels the upper end of the lever. and also the valve, to swing from right to left. this operation communication is established between the interior of the pipe 6, and the interior of the combustion chambe As soon. as the wheel leaves the spring l "forces the valve and its. lever to its normal position which is to shut oil the communication ofthe combustion chamber Withthe pipe 6. In this operation the spring 14: is assisted by the lever This lever has two elbows, one bends from the right to the left and in its turn is located the the not the front so the lower part of the lever will be in contact with the CHCIJII'IFQLOUCG o't ivheel'P, but Wlll be operated by the pm of the transverse bar ll, pass through. ahole of the lateral ear of the lever Y, and in order to prevent this lever from slippmg out from the pin, a head is inserted on the end I of the pm. As 1 S seen, this pin acts as a tulcrum for the lever-Y and will not interfere with the movement of the: lever l As soon as the lever V leaves the segment Q, the

' lower end of the lever Y is engaged by the mit the levers-V and V to swing from right.

to left and vice versa. la the center of the bar is bolted the arm 18; this projects in front of the motorand at its end is hinged the lever 19, which extends upward, and by proper bending, meets (with the other levers marked with the same number) in the center and in front of the motor. By pushing the upper end of the lever toward the motor thetransverse bar 17, will be pulled back and will carry with it the levers V-VY--Y, by so doing the valves will be disconnected and the result Will be that the working oi the combustion chamber will be stopped. The Wheel P, continuing its run, will cause the pin S to strike the lever Til; this will the segment (,3

fulcrum l6, and the other projects from The pins 16, which are fixed to the ears and the fixed palettes are disposed inalterchamber.

The turbine B, is composed of a drum 2O,v

set in the frame composed of the plates 21- 22 and a tube 23, in Whichis inserted the shaft C and to this shaft is secured the turbine. On top of the drum are secured the moving blades 24. The turbine is covered by a double casing; in the innercasing 25,

are secured the fixed blades 42. The moving 'nate rows, firstrow will be the moving blades, the second row of 'fixed blades, etc. The inner casing will be as near as possible to the top of the moving blades and the lower part of the fixed blades Will be as near as possible to the drum. I

Each side of the drum terminates in two ribs 26-27. These ribs run in annular grooves in plates u and 28. The ribs should be made to fit in the annular groove as perfectly as possible.

Theturbine is inclosed by the plates at and 28; the plate u separates the turbine from the box holding the combustion chambers and in this plate are bored the nozzles 43 for the.combustion chamber and for the' steam 44. To these plates are bolted the casing 25 and the exterior casing 30, which, with the inner casing and the two side plates form the Water jacket 31 for the turbine. On the top of the water jacket is secured the steam chest 32, from which departs the steam pi e 33. This steam pipe passes through t e water. jacket of the combustion chamber, and is connected to the circular pipe 45, which is incased on the plate u.-

From this circular pipe depart the steam nozzles 44; the steam ejected by these nozzles strikes the moving palettes of the turbine at the same angle as the gases whichare ejected by the nozzles of the explosion chambers.

The water jackets 15 and 31 are in communication with each other through open-- ings 35 of the plate u. The Water is injected into the Water jackets by the pump 36, through the pipe 37, and the condensed steam returns to the condenser 38 through the pipe 39. The pump 41 is used to lubricate the different parts of the motor.

To start the motor, disconnect first the feeding valves 9 and 2, next, by some means turn the shaft C so as to start the pumps for the air compressor and the gas generator, until the accumulators b and e, and the 'tubular rings (Z and r, and the pipes e and s, are filled to the proper pressure with air .and gas. When the pressure is reached, open the valves g and t of one combustion chamber, turn the shaft 0 again until the first explosion occurs, next open the valves of allcombustion chambers. To reduce the speed, shut off one or more combustion chambers from the feed. As soon as there is some steam accumulated in the steam chest (the water jacket will produce steam in a few minutes after the motor is started) open the steam valve by moving the lever 40 from right to left. The steam in the turbine has .a double function; first, it prevents the heat produced by the explosions, from reaching a high temperature in the turbine which would otherwise be red hot in about fifteen minutes and the consequence would be to put out of commission the motor; second, the steam adds power to the motor. To stop the motor, shut off all the feeding valves.

For the motor of which these are the specifications, any style of turbine can be used according to the purpose to which it is to be put.

The motor above described has the advantage that no power is lost, as almost all the heat energy is transformed into kinetic energy, and by so doing it is possible to se cure a motorwhich is lighter than any other motor, per H. P. which will develop. Another advantage is: that an indefinite number of motors can be operated with a single supply of feed.
