EXPLOSIVE ENGINE.
Specicaton of Letters Patent.
Patented May 9, 1922.
Application filed March 5, 1919. Serial No. 280,725.
To all fwwm t may conce/m:
Be it known that I, OSCAR E. KALLwrrz, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Explosive Engines, of which the following is a specification.
My invention relates to improvements in explosive engines, and has for its object the provision of an improved construction of this character which is of simple construction and elicient in operation. V
Other objects will appear hereinafter.
The invention consists in the combinations and arrangements of parts hereinafter described and claimed. Y
The invention will be'best understood by reference to the accompanying drawings forming a part of this specification, and in which,
Fig. 1, is avertical central section of an engine embodying the invention, i y
F ig. 2,`a top plan view of the same, shown partially in horizontal section,
Fig. 3, a medial horizontal section ,taken through the cylinder of said engine, and
Fig. 4, a horizontal section taken through the inner end of the sleeve valves piston. y
The preferred `form of construction, as illustrated in the drawings, comprises a suit-` able crank case"5 having the usual crank shaft 6 operating therein and a cylinder casing 7 projecting upwardly therefrom. The cylinder casing 7 is long enough to constitute two axially aligning cylinders, and carries a spark plug 8 at its outer end and is equipped with a suitable cooling jacket 9, as indicated. A cylindrical sleeve valve 10 is adapted to reciprocate within the cylinder 7 and is open at both ends, said sleeve valve being connected by a connecting rod 11 with a crank pin 12 on the valve shaft 13, which is geared by means of a sprocket chain 14 with the crank shaft 6, as indicated. Another sleeve valve 15 is adapted to operate within the sleeve valve 10, and is connected by a connecting rod 16 with crank pin 17 of the valve shaft 13, as shown. The sleeve valve 15 is divided by a central partition 18 into outer and inner cylinders, and pistons 19 and 2O are arranged to reciprocate within these cylinders. Said pistons are connected by a connecting rod 21 passing through par of said Vpurpose at the proper time.
tition 18, and innermost piston 2O is connected by connecting rod 22 with the crank shaft 6, as shown. This arrangement leaves a dead air chamber between the heads 18 and 19, which has no particular function in connection with the operation of the engine. A charge intake pipe 23 leads into the outer end of the inner cylinder through a port 24 controlled by ports 25 and 26 in the sleeve valves 10 and 15, respectively. An exhaust port 27 leads from the outer end of said inner cylinder and is controlled by ports 28 and 29 in valves 10 and 15, respectively, said exhaust port 27 being connected by a by-pass pipe 30 with an inlet port 31 communicating with the outer end of the outer cylinder and controlled by ports 32 and 33 in the sleeve valves 10 and 15. An exhaust port 34 leads from the outer end of the outer cylinder, being controlled by ports 35 and 36in the sleeve valves 15 and 10, and leads to an exhaust pipe 37, as shown.. An inwardly extending cylinder head38 is formed at the outer end of cylinder 7 and lits within the outer end of sleeve valve 15, constituting the cylinder head of the outer explosive cylinder,
The arrangement is such that, during each cycle of operation, an explosive charge is drawn into the outer end of the innermost cylinder through pipe 23, which leads to, an ordinary carburetor, and ports 24, 25 and 26, which are brought into registration for this The charge thus drawn into the inner 'cylinder is compressed therein, and when compressed is discharged through ports 27, 28 and 29, passing through pipe 30 into the outer end of the outer cylinder through ports 31, 32 and 33, said ports being brought into registration at the proper time for this purpose, as will be readily understood. The ports 31, 32 and 33 then close, and the compressed charge is reeexpanded in the outermost cylinder by the succeeding.movement of the piston 19. The charge is again compressed by the next movement of the piston 19 and is exploded by spark plug 8 at the end of such compression in the usual way. The power stroke ofthe piston 19 then takes place, operating the crank shaft 6 in the usual way. At the end of this power stroke, ports 34, 35 and 36 are brought into registration and thus opened to permit exhausting of the burnt gases which are expelled from the outermost cylinder by the next stroke of the piston 19. At the end of this exhausting or scavenging stroke of the piston 19 ports l l2 and 3?. again open as before; to admit a new charge; and the cycle of operations is repeated as above outlined. lt will be observed that the new charge is repeatedly expanded and compressed, which tends to mix the combustible vapors or gases thoroughly with the air and break up the same; tending toward efficiency in operation and economy in fuel consumption. Thus7 while the outer cylinder operates on the four-cycle principle, and goed scavenging is obtained, the incoming charge is expanded and compressed before explosion, as in the two-cycle engine; and great efiiciency and fuel economy ol; tained. The specific form and arrangement of parts is a simple and effective one for the purpose.
While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefor-e, do not wish to be limited to the precise details of construction set forth, but
desire to avail myself of such variations and modifications as come within the scope of the appended claims. i
