Patented Oct. 1'7, 1911. Renewed March 6, 1908. Serial No. 419,569.

To all whom it may concern:

Be it known that 1, MICHAEL H. SULLIVAX, a citizen of the United States, residing at Poughkeepsie, in the county of Dutchess and State of New York, have invented new and useful Improvements in Rotary Compound Explosive-Engines, of which the following is a specification. Y

My intention is an improved rotary compound explosive engineand its primary object is to provide an engine in which both the pressure energy and the velocity or impact energy of gases may be utilized to the fullest extent, this object being attained by providing a rotary motor having rotary pistons and means for generating and exploding an explosive mixture which is directed against the pistons to utilize the explosive or pressure energy of the gases, and by connecting to the motor shaft so as to turn therewith, impact vanes or buckets against which the gases discharged from the rotary motor are directed soas to utilize the impact or velocity energy of said gases and thus compound the action of the engine.

A further object is to provide an improved form of engine ofthis class having a revoluble wheelprovided with pistons and with vanes or buckets, means to apply fluid under high pressure to the said pistons, to rotate said revoluble wheel, and an accumulator into which the exhaust discharges and in which the same expands, said accumulator supplying fluid for operation against the vanes or buckets and compounding the action of the engine.

In the accompanying drawings, Figure 1 is'a top plan view of an engine embodying my improvements; Fig. 2 is an elevation of the same,'the shaft being shown in section on the plane indicated by the line w-a of.

Fig. 1; Fig. 3 is a detail perspective view from'the inner side, showing one of the" casing sections; Fig. 4 is a similar View, showing the other casing section ,Fig. 5 is a. vertical transverse sectional view, taken on the plane indicated by the line 6-1) of Fig. 1; Fig. 6 is a detail elevation of the revoluble element; Fig. 7 is a detail elevation of one of the pistons of the revoluble element; Fig. 8 is a sectional View, taken on the. plane indicated by the line (;0 of Fig. 1, and intersecting the carburetor or vaporizer; Fig. 9 is a detail sectional view of one of the combustion chambers, illustrating its reto the combustion chamber and controls communication between the combustion chamber and the piston chamber, to permit the charge when exploded to expend its force in. the piston chamber; Fig. '10 is a vertical longitudinal central sectional view of my improved engine, and Fig. 11 is a detail sectional view of one of the packing rings of the piston-carrying wheel and its connect-ions.

The casing 1 of my improved engine is composedof two sections 2, 3. The section 2 has the portion 4 which is cylindrical in form and of enlarged diameter, and the portion 5, which is also cylindrical in form, is of smaller diameter than the portion 4, and is on one side thereof. The enlarged portion 4 forms a cylindrical wheel chamber 6 for the revolving piston-carrying wheel 7. The section 3 comprises a flat, circular inner portion-8 which is bolted to one side of the section 2 by bolts 9, said section 2 having a peripheral flange 10 through which the said b'olts pass. The said Section 3 also journaled in thrust bearings 14 which are provided with adjusting screws 15, the inner ends of which are stepped in recesses in the ends of said shaft. The said screws prevent ii casual'endwise movement of the shaft and corresponding. transverse movement of the wheel 7, and also enable the shaft and wheel to be adjusted to prevent undue friction between either side of the wheel and either side of the casing.

The wheel 7 is provided with a plurality of radially-disposed slots 16, two being the preferred number, as here shown, and arranged diametrically opposite each other. The said slots extend from within a suitable distance of the center of the wheel to within a suitable distance fromthe periphery thereof, and within each of said slots is placed a piston 17 which is slidable therein transversely with reference to the wheel.

In the sides of the said slots are antifriction'rollers that when the sections are united, theinner points 19 of one section will be arranged opposite the extreme outer points ,20 of the opposite section, and as the edges 19 of each sect-ion abut against the wheel 7, it will be seen that I provide a series of four separate and distinct chambers 21 in which the pistons operate. a

' In the inner face of the periphery of the enlarged portion 4 of the casing section 2 is.

a cam groove 22 which extends obliquely across the same and annular'l within the said casing section, and whic is parallel at all points with the walls 'in the ends of the casing section. Each piston 17 has a pin 23 projecting from its outer'side, at 1ts center, and on the outer end of which is mounted an anti-friction roller 24 which travels in the cam groove 22 and coacts with said cam groove toimpart reciprocating movement to the piston. The peripheral portion of the' wheel 7 is provided with transverse slots 25 in which operate antifriction rollers 26 which are journaled on the said pins 23. The wheel 7 is provided on opposite sides, at suitable distances from its center, and pe'ripher with concentrically-disposed packing rings 27 which are recessed therein and each of which is provided with a plurality of inwardly, extending studs 28 which enter the transverse openings in the wheel, have their inner ends hollowed, and are provided with coil springs 29 which act to keep the said packing rings in contact with the'sides of the casing. It will be understood that said packing rings are carried by andrevolve with the sald wheel. The abutments formed by the irregular end Walls of the casing sections are provided at their'apexes with packing plates 30 which are held-by springs 31 in frictional engagement with the sides of the wheel. One of the piston chambers 21 in eachside of the piston casing has an inlet channel 31 and an exhaust port 32, and the casing has an accumulating, or expanding chamber 33 formed therein, here shown as extending nearly entirely around-the same and termina'ting in a discharge port 34, in which is placed a nozzle 35 that is disposed obliquely with reference to and discharges correspondingly against one side of the. .wheel 7, near the periphery. thereof. The peripheral portion of thewheel 7 is provided with obliquely-disposed transverse chambers 36 which form. impact vanes, against which strike the exhaust products discharged from the piston chambers into the accumulating .port 31. cams 58 on the shaft, said camsbeing so 'timed as tofirst open and close the valve 56,

or expanding chamber 33 and discharged from said chamber 33 so that the exhaust gases or products are utilized in rotating the piston-carrying wheel, thereby compounding the action of the engine, as will be understood. The exhaust is indicatedat 73. One piston chamber in each section of the casing is provided with a cold air intake" port 37 and an air discharge port 38. The shaft 13 drives an air compressor 39 which ,75 com resses air in a tank or reservoir 40.

-T e compressed air tank is connected by pipes 41 with Vaporizers 42, each of which comprises an inner, vaporizing chamber 43, and an outer, heating chamber 44,"which extends around but does not communicate with the vaporizing chamber. In the vaporizing chamber is a cylindrical .valve chamber 45 in which operates an oil feed valve 46, which is cylindrical in form and has an annular recess 47 that forms an oil duct. A port 48 connects the valve chamber with the vaporizing chamber, and there is an oil-supply pipe 74 that leads to said valve chamber. A spring 50 normally-maintains the valve 46 in position to cut off communication between the oil-supply pipe and the vaporizing chamber. Said valve has a rod 51 provided with a tappet roller 52 which bears against a cam 53 on the shaft, said cam acting once at each rotation of the shaft to move the valve against the tension of the spring, so that the oil duct registers with the oil supply pipe and the port '48,'and hence causes a charge of oil to be fed to the vaporizing chamber. The pipe 41 .communicates with the vaporizing chamber, so that the latter is supplied with compressed air, heated by radiation from the heating chamber 44, and hence the oil serves to carburet theair, the oil and air forming a highly combustible and explosive vapor or gas, as will be understood. Each section of the casing 1 has on its outer side a combustion chamber 54 which c'ommunicates with one of the ports 31 and also communicates with the vaporizing chamber of one of the vaporizers'by a duct 55. Said duct is normally closed by a valve 56. -A

spring-pressed valve 57 normally closes the The said valves are operated by to charge the combustion chamber, and to then open the valve 57 at the instant of the lgnit ion and explosion of'the charge, so that the force of theexploded charge will pass into -one of the chambers 21, behind one of the pistons, to revolve the piston-carrying wheel. The respective combustion chambers with their valves, on opposite sides of the casing, are so located that the charges therein are alternately exploded and their force directed. into chambers 21 on opposite sides of the wheel, thereby causing the latter to run steadily and evenly. 13)

" said chamber being air reservoir.

the outer air or 'to a suitable It will be understood that the'iorce of the exploded charges acts on the pistons in only one of the chambers 21 on each side of the wheel. The other of suchchambers oneach side of the wheel has its port "37 provided with a cold air intake pipe 59, and its port 38 connected by a pipe '60 to the outer, heating chamber 44 of one of the vaporizer-s, ovidd also with a discharge pipe 61 which may l'e'ad'either to gas producer or carbureter, as may be desire It will be understood that at each rotatioh of the wheel, cold air will be sucked into one of the chambers 21 on each side thereof, which will prevent overheatin of 'the engine, the air will be highly hea'te and will be driveh through the outer, heating chambers of the Vaporizers before being discharged, and

hence the heated air will serve to keep the Vaporizers heated to the degree required to vaporize' the carbureted 'air ed to the vaporizing chambers thereof from the compressed Each combustioh chamber has a sparker or igniter 62, here indicated as an electric sparker, and said s arkers are operated by cams "63 on the sha From the compressed air tank or 1'eser-. voir 40 leads a pipe 64 which communicates with the chambers 21 in which the'pistonsf .operate through branch pipes 66'. A valve said valve is opened,

(pipes, and when the enthereby admitting compressed air directly intothe piston chambers and utilizing the compressed air to start the engine; Said valve *is then. closed, and the engine con:

tinues to operate, as before described.

The air compressor 39 is similar in construction to the casing 1, and the pistoncarrying wheel therein, the wheel inwthe air compressor bein operated directly by the engine shaft. T e said air compressor-has an air inlet valve 68. The compressed air tank or reservoir 40 communicates with a cylinder 69, in which is a piston 70 which is moved in one direction by a spring 71, and, Y

upon an excess of pressure in the said tank or reservoir 40, is moved 1n the opposlte d1- rectlon by the said excess pressure. A link 72 is here shown asconnecting the said pisj ton to the lever of the valve 68, so that on i an excess of pressure of air in the tank 40, the piston 70 will be operated to close or partly close the'valve 168, as the case may be, to put the air compressor either entirely or partly out of. action, and hence diminish engine from running at too high a rate of speed.

From the foregoing, it will be seen that in utilized to the fullest 'quently, more of the original heat in the gases is converted into useful mechanical charges and directing them against the ro-' any high pressure pistons I arrange impact vanes o'r buckets to rothte with the motor shaft, and i provide ah accumulator which receives the gases from the rotary exp'ld'siv'e motor and directs them "against the impact vanes or buckets to compound the a'ct'o'n of the "engine. utilizing rotary high pressure pistons, a very high speed can be. developed and in associating with such r'otary pistons, "the impact or turbine vanes to receive the velocity or impact energy in the gases after they leave the high pressure piston chambers, bOththe pressure energy and the velocity energy of the ases are extent and, consework than 'in other engines in use at the present time. 7
