Be it known that I, RALPH RAGAN,-.a c1t1- zen of the United States, residing at At: lanta, in the countyof Fulton and State of Georgia, havefinvented anew and useful Explosive-Engine, of which the following is a specification,

This invention relates "to improvements in explosive engines, and the primary obj ect of this invention is the provision of a supplemental air and gas mixing and compressing cylinder disposed in parallel with the main or engine cylinder of a reclprocatlng explosive engine, the same being provided with an explosive chamber at each end thereof, and adapted to explode at every stroke, a series of rotary valves interposed between the carburetor and the gas and an compressing and mixing chamber and between the gas and air! mixing chamber and the explosive cylinder of the engine.

A further object of this invention is the provision of an explosive engine and air mixing and compressing cylinder so disposed with relation to the explosive cylinder as to feed thereto, in alternation, the desired quantity ofcarbureted and mixed air under pressure, so that the compression stroke of theexplosive engine Wlll be to a great extent reduced, and whereby the efii- 'ciency of the explosive charge or pressure exerted upon the piston of the cylinder will be greatly increased.

A stiilfurther object of this invention is the provision of an explosive engine having a carbureter, a double acting gas mixing and supplying cylinder disposed to. receive the carbureted' air from the carburetor, a valve interposed therebetween to regulate the flow of carbureted air from the carbureter to the respective ends of the said cylinder, an exsive force.

plosive cylinder provided'with two explosive and compression chambers in opposedends adapted to receivethe compressed and mixed carburetedair from the compressioncylinder, with a valve interposed therebetween for permitting the entrance of the carbureted air at-the desired end of the cylinder to obtain from the said compressed carbureted air the maximum amount of explo- A still further object of this invention is the provision of an explosive enginehavi-ng a reciprocating piston mounted therein and adapted to be acted upon by explosive charges at the ends thereof, vthe exhaust;

therefrom being near the central portion and carried away from the cylinder, so as to in no way affect the'heating of the charge dee livered thereto, or the adjacent parts of the machine for delivering said explosive charge I to the cylinder.

A still further object of this invention, is the provision of means operably connected j to the drive shaft of the engine, whereby the carbureted air mixing and compressingcylinder, the piston in the explosive cylinder. and the two sets of rotary valves for 'delivering the carbureted air to thecompression cylinder and from the compression cylinder to the'explosive cylinder may be operated in train or time.

WVith the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made withn the scope of what is claimed, without departing from the spirit of the invention.

' detailso'f construction hereinafter described In the drawings :Figure 1 is a side elevation of the complete engine. Fig. 2 is an elevationlooking from the compression cyl- -inderside thereof. Fig/3 is a longitudinal sectional view taken on line 3+3 of'Fig. 4.

Fig. 4 is a top plan view of the complete engine. Fig. 5 is a detail sectional view of one of the rotary valves and its casing. Fig. 6

is an enlarged detail sectional view on the line 66 of Fig. 5.

Referringto the drawings, the numeral 1 designates the main frame of the engine pro vided at its lowerendfwith the shaft bearings or journals 1 for the reception of the shaftQ, the same being provided with the crank 3 disposed between the lower members of theframe atthe base of the engine. Op

erably connectedto the crank 3 is a piston rod 4e and disposed in the upper end of the frame-work of the engine is an explosive cylinder 5, said rod 4 entering said cylinder at the lower end thereof andcarrying reciprocatingly within said cylinder or rather the bore'thereof, a piston 6, which is'provided with the two series 7 and 7 of split packing rings, and the central oilreceiving groove 8 being provided circumferentially of said piston. Carried by and disposed upon opposite ends of the said'piston are the battle I plates 9 and 9 respectively, which are adapted to convey the explosive charge to the respective explosive engine while the burned charge enters the exhaust outlet 40 or 40, as will later appear.

The cylinder 5 as clearly shown in Fig. 3 is provided at its opposite ends with the explosive compartments or chambers 10 and 10, in the outer walls of which are mounted the spark plug receiving means 11 for the spark plugs 11, whereby the charge compressed within the respective ends of the cylinder may be exploded at the proper time to give the maximum power to the stroke of the piston.

Surrounding the complete cylinder 5 is a copper jacket 12 which provides a water space for cooling the cylinder and in order to feed water thereto a supply pipe 13 is provided with the two branches 14 and 14 in communication with the space within said jacket and exhausts through the outlet pipe 15, as clearly shown in Fig. 3.

Properly supported from the upper portion of the framework 1 by means of the two arms 16 and 16' are the heads 17 and 17 of the air compressing and supplying cylinder 18, the diameter and length of which are identical with the diameter and length of stroke of the cylinder 5, the tie rods a being employed to retain the heads 17 and 17 upon the respective ends of the cylinder or tube 18. Mounted for reciprocation within the cylinder 18 is a plunger or piston head 19 provided with a series of packing rings 19 and connected for operation to the piston rod 20, said head 19 being adapted to be operated to assume the opposite position to the piston head 6 within the cylinder 5, so that explosive mixture is compressed and delivered to the cylinder 5 at the proper time, that is as clearly shown in Fig. 3 the lower end 10 of the cylinder 5 having the fully compressed explosive charge and ready for exploding the same whereas the compartment 10 has had its charge exploded propelling the piston 6 downwardly to the exhausting position, where the baffle plate 9 has conducted the exhaust charge to the port 40 and the piston 19 has delivered its charge to the upper portion of the cylinder '5, to be compressed and exploded upon the upward stroke of the piston 6 and in the compartment 10, as the piston 19 is moved down in an opposite direction to the piston 6. In order to accomplish the proper reciprocation of the piston 19 within the air compressing and feeding cylinder 18, the piston rod 20 is provided with the adjusting sleeve 21 whereby the same may be lengthened or shortened and its pin 22 carried in the lower end thereof, is mounted for a sliding movement within the slot 23 of the crank 24 carried upon the end of the shaft 2, said crank 24 being disposed in opposite direction to the crank 3 of the shaft, the slot 23 permitting a slight sliding retarding motion to the piston 19, the purpose of which will presently appear.

Disposed to one side of the frame is the carbureter 25, having a manifold 26 leading therefrom to the casing 27 from which lead, in the opposite direction from the manifold, the two carbureted air conducting conduits or pipes 28 and 29, respectively, the conduit or pipe 28 leading to the pipe 30 into the upper end of the gas and air compressing cylinder 18, while the conduit or pipe 29 leads to the branch pipe 29 and to the inlet pipe 31 to the lower end of the cylinder. Leading from the conduit 30 in opposite direction to the conduit 28 is a conduit 33, while leading from the conduit 31 at the lower end of the cylinder 18 is a branch 34 which leads to the conduit 35, said conduits 33 and 35 being in communication with the cylinder 36 on the same side thereof so that the carbureted and mixed air compressed and fed by the cylinder 18 and its piston 19 is supplied to the casing 36 and from there through the inlet conduits 37 and 38 to the ports 39 and 39' of the cylinder 5.

As before mentioned leading from the cylinder 5, are the two exhaust ports 40 and 40, which as shown in Fig. 4, are covered by the branch conduits or exhaust manifolds 41 and 41 which lead to the exhaust pipe 42, thereby conducting the explosive discharges away from the cylinder of the engine so that the heat conducted thereby will not interfere with the parts thereof.

Keyed upon and rotatable with the shaft 2 is a gear 43 which meshes with a gear 44 whose small beveled pinion 45 meshes with and transmits motion to the beveled pinion 46 carried upon the lower end of the vertical shaft 47, which has connected thereon inter mediate of its ends a beveled pinion 48, which meshes with a beveled pinion 49 upon the horizontal and transverse shaft 50, whose pinion 51 meshes with a pinion 52 and whereby the rotation of the shaft 2 will convey simultaneous motion and in time to the vertical shafts 53 and 47 of the respective rotary valves, as shown in detail in Figs. 5 and 6, and which are mounted within the respective cylinders or chambers 27 and 36. As both of these valves are of the same construction, the description of one will be sufficient, and therefore by referring to Figs. 5 and 6 of the drawings it will be seen that the rotary valves mounted within said cylinders 27 and 36 will accomplish the desired result by operating in time to permit the carbureted air to be first admitted to therespective ends of the cylinder 18 and therein to be delivered at the proper time to the cylinder 36, whose valve will dispense the carbureted air at the proper time to the bore of the cylinder 5 to be exploded at the desired stroke of the piston 6 within the bore of the cylinder the actuation thereof operating the crank shaft and the various mechanisms operable therefrom.

In Fig. 5 the cylinder 86 is illustrated and the bore thereof is slightly tapered and has mounted therein a tapered rotary valve 58, the shaft 47 having slidably connected thereto the small shaft 47, passing through a stuffing box 54 whose upper end has mounted thereupon as at 55 a ball race for the reception of the balls 56, the cone bearing 57 being provided at the upper end of the shaft 47 and carrying the rotary valve 58 prosaid coil spring 62 exerting a tension to pull the shaft 47 and the rotary valve 58 downwardly. e

As clearly shown in Fig. 3 a novel form of stuffing box and lubricating device is provided for the piston rod 4: as it enters the cylinder 5, the same being so constructed as to withstand the great force of the explosion as the piston 6 is driven upwardly, and

at the same time prevent the escape of oil from the chamber 62 providedwithin the casing 63 which is formed or inserted in'the lower end of the cylinder 5, and in this oasing 63 is mounted the packing material 64 and the stuffing box 65, an oil lead 66 entering the casing 65so that the oil is admitted to flow through the channel 0 into the chamber 62 and properly lubricate the piston rod 4 as the same is reciprocated. ,Two split metallic packing rings 62 and 62 havinga tendency to contract around the piston rod 4, are mounted in the casing 63 at the upper and lower ends thereof. 'In order to admit the oil upon the down stroke of the piston 6, a valve 67 is mounted within the conduit or pipe 66 and has its arm 68 connected to a link 69, which is operably connected to the crank shaft, (not shown), at a proper time so as to permit the oil to flow from a pump system to the chamber 62 at the desired time and be checked by the valve 67 at the proper time to prevent escape of oil to the explosive charge within the bore of the cylinder5. i I

As clearly illustrated, the rotary valves are so mounted and connected for operation as .to act as check valves during the explosion at each explosive stroke of the piston 6,

and at the proper timeto permiteither port 59 and 59 to admit carbureted air to the cylinder 5, thus providing a combined double check and admission valve in each cylinder 27 and 36.

From the foregoing description taken in connection with the drawings, it-is evident that "by constructing an engine according to this invention the carbureted air delivered theretois thoroughly mixed and compressed before the same is compressed within the cylinder 5 and the explosion from the explosive charge increased to a maximum; and by providing an engine. which willex-J plode at each stroke, or twice during the full reciprocation thereof, the maximum 'amount of power is secured. Further by a cooling or jacketing means for the. ylinder 5 of the engine. U
