GAS TURBINE-ENGINE.

To all whom it may concern: Be it known that I, Jacques ALFRED Momn, a British subject, residing in the city of Quebec, Province of Quebec, Canada, have invented anew and useful Gas Turbine-Engine Using Gas or Gasolene or Petroleum-Oil and Gasolene. Comb ned, of which the following is a specification.

The invention to be hereinafter described relates to internal combustion engines.

In order to more clearly disclose the construction, operation, and use ofthe nvention, reference shouldbe had to the accomr.

panying drawingsforming part of the present application.

Throughout the several figures of the drawings like reference characters designate the same parts.

pump; Fig.- 6 is a central, vertical, longitudinal, cross section through the entire machine, assemb1ed.

The main objects of the invention are to provide a simple, efiicient, durable, economr cal, and compact combined rotary internal combustion engine and rotary cooperating tween E and F is clamped an annular wall of the motor casing or B forming the body F and G is secured a cylinder. Between similar annular wall C, forming the body' of the compressor casing. These walls B and C are secured in position by bolts 6 passed through holes 7 in the plates and G and into the walls B and C, respectively; and by bolts 6 passed through wall and as clearly shown in Fig. 6.

The outer face of the Wall E is circular, but the entire inner circumference is not Patented Mar. 9, 1915. Y

truly circular and concentric therewith,

though it has two diametrically opposite portions 12 concentric therewith, the inter vening spaces 11 being cut out to form eccentric explosion chambers as shown in Fig. 2. Keyed to shaft K and freely revoluble within the motor casing, is.a rotor L provided with three substantially triangular piston pockets in the rim 9. In these pockets are pivoted swinging pistons D each actuated outwardly by a spring 30. To prevent a retarding vacuum which would normally be formed by the outward movement of the piston, a bore 31 is made through each piston to afford a vent for the chamber beneath the piston to and from the piston pockets. At each piston pocket the rim 9 is extended inwardly at N to form a support or base to which gas check plates J may be screwed .75 or otherwise connected to prevent leakage f of gas from the pockets tothe interior of I or. the like seated in recesses 2 cut in the inner faces of the rings at intervals. In order to prevent escape of gas between the adjacent concentric surfaces of the'wall B and rotor rim, semi elliptical bars 10 are seated in key ways or grooves of the concen'-' tric portions of the wall B in such manner that one longitudinal edge of each bears r lightly upon the face of the rim of the rotor throughout its width. Suitable leaf springs or the like, seated in recesses in the bars and ative position.

The explosion takes place in the rear of the swinging pistons. The rear ofeach piston is arch shaped, forming a forwardly directed angle between the wall B and the uper part of the rear face of the piston.

hus, an explosion occurring at the, rear would have a wedgin probably drive the piston into its pocket and escape toward the exhaust passage outlet 17 without any driving effect. To prethe wall B, act to maintain the bars in operaction whicli would vent this, a rocking friction plate 32 is slidably and rotatably seated in a part circular groove of about 225, in the rear upper edge of each piston. This plate has a wide surface which travels in sliding contact with the inner face of the wall B and a rear inclined wall which forms an angle with the rear face of the piston. The explosion, impinging equally against this face and the rear face of the piston, assists in maintaining a gas tight traveling contact between the friction plate and the wall B. The gas is admitted to the explosion chambers through valves 13 provided with spindles 15 and rotatably mounted in the wall B. Each valve spindle is-provided with a lever arm 34 carrying a roller 35 adapted to be engaged by successivecams 33 on a cam disk 0 keyed to the shaft'K. This disk is so positioned on the shaft K as to have the cams 33 engage and actuate the arms 34 for admission of gas at the instant that the friction plate 32 of each piston passes the fuel inlet, and the cams are so proportioned as to maintain the valves in open position until the pistons have traveled a pre-determined distance beyond this point, thus permitting admission of a fixed volume or charge of fuel behind the abutment. As each cam passes beyond theroller 35, a spring 37 connected at its 0pposite ends to the lever 34 and the motor casing, respectively, .Will swing the lever 34 back, closing the valve. Each valve is providedwith' 'an are shaped portion 16 traveling in a. recess in the wall B and falling flush across the gas inlet opening, while the valve is in inoperative position, giving a smooth even surface for the free travel of the pistons, and their friction plates 32. The spent gas of each explosion is wiped out through the exhaust opening 17 by the succeeding piston, passes into an exhaust channel 18, thence into a connecting tube 66 which delivers-it into a U shaped exhaust pipe 67 at the opposite end of the machine. The passages 18 lead through thewall B of the motor and the wall 0 of the compressor.

In the wall of each explosion chamber is a bore 36 to receive a spark plug from which extends a spring terminal 42 which 006 crateswith a similar terminal 40 secure in the wall B andprojecting inwardly. As the disk 0 rotates, studs 39 thereon engage the terminals 40 and carry them toward the ternals 42, completing the circuitand making the spark. The studs 39 are so, arranged'as to make the spark immediately; after the valve 13 has been closed, of course] In order to cool the motor casing, it is water jacketed by intercommunicating pas sages and conduits 11 Figs. 2 and 6 throughout the width of the wall B and through the adjacent parts of the walls E and F as clearly shown in Fig. 6. As shown in Fig. "9. some of these conduits extend through 7 the wall 13 where this wall is concentric with the rotor L and, thus, throughcooling this part of the wall, also'act'to cool therotor face.

The compressor, for the most part, is constructed in substantially the same manner as the motor and, therefore, need not be so minutely described"- It comprises end walls F and G, and body wall C. Within the wall C is mounted rotorI keyed to theshaft K and having inwardly extending parts'n of its rim corresponding to parts N of "r0 tor L. Portions 20 013 the wall Q are'conc'en tric with the rotor and the intervening-portions form eccentric compression chambers 21 leading to passages 25 opening into gas reservoirs 19, the inner ends of the openings being closed by spring pressed flap valves- 26. The enlargements 'n of the rim are provided with lateral arcuate groovesto receive the are shaped rear plate of U shaped pivotally mounted swinging pistons dark tuated tooperative position by leaf'springs;

Relief 30 Fig.4, or the like. through the rim to the bottoms 0f? the grooves permit free swinging of thepistons.

sion valves 23, and .the' following piston will compress this charge through the passage 25 and valve 26,.andj into the gas neserv'oir:

19. The quantity admitted to the compression chambers 21 is governed "by th'eacontrolling valves 23" having are shaped plates? 24 for closing" the inlets To ,theuspindle of:

each of these valves is connected one arm of a bellcrankhand lever 45, which is jourfuel from carbnreters or other suitable sources of supply through inlets 69, all as shown in Figs. 4 and 5.

The reservoirs 19'are simple continnations 'naled 8d a 9 2 i' if i a ing with ameans? 'fixed tozthe. end;.wn;ll-

of the fuel conduits or passages I'Q'in' 'the motor casing. /The flap valves 26 prevent any possible back flow of the fuel when the machine stops, thus always leaving a supply of fuel ready for starting. Thus, during the operation of the motor, the'compressor is continually compressing new charges of fuel into the reservoirs 19 as fast various passages as it is delivered from them into the explosion chambers. If desired, the carbureters and their immediately coiiperating parts and connections may be omitted. Instead of drawing the fuel from carbureters, ready mixed, the petroleum or gas vapor, and the air, may be delivered separately but in the proper proportions to the compression chambers. Thus, the vapor may be delivered into each compression chamber direct by simply coupling a supply pipe to a suitable bore which is normally closed by a removable plug 38 in the wall of each chamber. The air will be drawn in through chambers 29, the pipe S and branches 68 being omitted. The proportion of air will be regulated by the valves 23 and hand levers 45.

In order to maintain a continuous and regular circulation through the passages and conduits z" of the motor casing, a rotar ump is used, driven direct from the she t This pump is detachably mounted in brackets 51 of wall G and is very similar in its general construction to the compressor. Therefore, only a brief mention of its arts will be necessary. It comprises a casing B Fig. 6 with pump shaft 54 carrying a rotor 58 in which are slidably mounted spring actuated swinging pistons 59 operating successively in a compression chamber 161 eccentric to the rotor. These pistons draw water in through the inlet 63 which is connected to the feed pipe, and drive it out through the delivery passage 62 which is connected to the supply passage or opening 53 of the circulation system of the jacket. After passing back and forth through the and conduits of the system, the water will pass out through the outlet 65 Fig. 4:. The pump is driven by means of a sprocket chain 56 passed about a sprocket wheel 55, fixed to shaft 154 and also about sprocket teeth formed on a collar or sleeve fixed to the shaft K, all as clearly shown in Fig. 6.

t is thought that the construction, operation, and use of the invention will be clear from the preceding detailed description.

The arts E, B, F, C, G constitute in effeet a xed continuous casing provided with the necessary fuel, exhaust and water passages and having its interior divided into two compartments for the rotors arranged side by side.

Changes may be made in the construction,

arrangement, and disposition of the several parts of the invention Without in any way departing from the field and scope of the same, and it is meant to includeall such within this application wherein only a preferred form has been disclosed.
