ROTARY EXPLOSIVE-ENGINE.
Specification of Letters Patent.
Patented Aug. 18, 1914.
Application filed August 26, 1913. Serial No. 786,775.
To all whom it may concern l Be it known that I, Emir I. ANDERSON, a citizen of the United States, residing at Chicago, in the county. of Cook and State of Illinois, have invented certain new and useful Improvement in Rotary Explosive-Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same This invention relates to new and useful improvements in rotary explosive engines and has for its object the-provision of a device of the above character which will combine the advantages of a rotary engine with those of the ordinary type of reciprocating engine.
Anotherobject of my invention is the provision of such a device wherein the gases are com re'ssed before being admitted to the explosion chamber, therebyv increasing the amount of explosion caused by the firmg of the gases.
A further object of my invention is the provision of such a device which will be positively operated thereby insuring a proper tlming of each of the working parts and eliminating any lost motion.
A still further object of my invention is the provision of such a device in which the expense of manufacture will be materially lessened and the power developed materially increased.
With the above and other objects in view I now proceed to describe my invention in the following specification and accompanying drawings, in which,
Figure-1 is a side view in elevation of my improved rotary explosive engine, Fig. 2 is an end view in elevation of my improved rotary explosive engine, Fig. 3 is a transverse sectional view of my improved engine taken on line 23-43 of Fig. 2, Fig. t is a longitudinal sectional view of my im'roved' engine taken on liue. 4-4 of Fig.1, tail view of the rocker arm used to operate the compressor, and Fig. 6 is a detail sectional view of the casing.
Referring to the drawings by characters of reference 1 indicates the casing of my imig. 5 is a de-- proved explosive engine, which is preferably rectangular in cross section and is adapted to form the annular chamber 2. This casing is preferably provided at its lateral extremities with suitable hearings, in which the axle 3, having secured thereto the fly-wheel 4, is journaled. This axle 3 also carries at 1ts end opposite the fly wheel a suitable spur ear 5, the use of which will be more fully iercinafter described. Inter.- mediate the ends of the axle 3 and rigidly secured thereto I also provide a rotor, indicated generally by the numeral' 6. This rotor preferably comprises the hub 7 having formed integrally therewith the radially extending spokes 8 to the outer ends of which is secured the rim 9 which is preferably recessed, as shown at 10, to form the pockets against which the explosion is adapted to exert pressure. 1 v
The casing'l is preferably provided with the inlet a erture 11 and the exhaust aperture 12. uitably secured to the casing in registration with the exhaust aperture I preferably provide a suitable exhaust pipe 13 which is held thereto by means of the flange 14. This flange 14 is provided with apertures through which the shanks of the bolts 15 areada ted to extend.
A suitable cy inder 16 is rovided at its lower end with the annular ange 17 which is curved to fit the contour of the casing, as"
clearly illustrated in Fig. 3. This cylinder 16 is also rovided intermediate its ends with a suita le inwardly extending annular fiange- 18 having formed therein the valve seat 19 with WlllCh the valve 20 is adapted to cooperate. A suitable inlet port 21 is formed in the side of the cylinder and is adapted to be closed by means of the valve 22, which is adapted'to admit the gas to the cylinder when the device is in operation.
A suitable piston 23 is slidably mounted in the cylinder and is adapted to be operated by the piston rod 24 which is pivotally secured thereto, by means of the pin 25. The upper end of this piston rod 15 preferably rovided with the annular groove 26 which 1s ada ted to receive the end of the rocker arm 2 This rocker arm is pivotally supported on the bracket 28 whic is secured to the side of the cylinder as clearly illustrated inl ig. 2. The end of the rocker arm 27, opposite the end which is connected to the piston, is preferably provided with a suit- -able aperture through which the operating rod is adapted to extend.
llivotally secured to the casing at a point immediately adjacent the cylinder I preferably provide atlap valve 2%.) which is adapted to form a closure for said cylinder and be intermittently opened when the engine is in operation, This flap valve is secured to the transversely extending axle 30 which is provided with an extension on which the arm 31 is adapted to b secured.
Secured to the casing and extending inwardly with relation thereto I preferably provide the brackets 32 on which are rotatably mounted the spur gears 33. These spur'gears 33 are adapted to mesh with the large spur gear 5 and be driven thereby. A suitable rod 34 is eccentrically secured to one of the ears 33 and is extended upwardly, as 0 early shown, and through, the aperture in the rocker arm 27, thereby causing the rocker arm to reciprocate. the piston 23, when the device is in operation. A rod simllar to the rod 34, which is indicated by the numeral 35, is eccentrically mounted, at 36, to the opposite gear wheel 33 and its upper end is connected to the arm 31, as 0 early illustrated by the numeral 37. Each of the rods 34: and 35 is carried in suitable bearings 38 which allow free movement of said rod and permit the device to operate without any interference. A chamber 39 is formed in the wall of said casing and is adapted to permit the exploded gases to enter thereinto and thereby eliminate a good deal of the noise due to the explosion of the gases in the cylinder of the motor.
A suitable spark plug 40 is.secure'd in the cyl nder 16 at a point just below/ the wall which separates the compression chamber from the explosion chamber. This plug is adapted to cause the compressed gases in the explosion chamber to be fired and thereby set the motor in operation.
It will be apparent from the foregoing that when it is desired to make use of my improved engine the same is connected to a suit-able source of gas-supply and gas is admitted to the compression chamber at the instant that the piston is raised. The gas is then forced downwardly and through the valve 18 into the explosion chamber, at which time, a contact is formed and the spark umps between the points of the spark plug, thereby firing the gas and causing the same to expand against the end of the recess 10 which is formed in the rotor. It will be obvious that the expansion of the gases ohave v will cause the rotor to revolve around its axis and. when the gas contained in the pocket of the rotor reaches the chamber 39 itagain expands, thereby reducing the pressure and eliminating considerable of the noise, caused by the explosion. This operation is repeated fourtin es in one revolution of the fly-wheel 4, thereby providing an engine which will give the greatest amoufit of power at a minimum of expense.
While in the foregoing I have shown and described the preferred embodiment of my invention I wish it to be understood that I may change the spepific arrangement and combination of parts without in any way departing from the spirit and scope of my invention as defined in the appended claims.
What is claimed is v 1.. A device of the character described comprising a casing, said casing forming an annular chamber, a cylinder operatively connected with said casing, said cylinder being divided into compression and explosion chambers, a valve adapted to form a closure I between said chambers, said valve being automatically operated by thecompression of the gases in the compression chamber, means to admit gases to the compression chamber, a spark plug in the explosion chamber to cause the gases to explode, a flap valve interposed between the explosion chamber and the annular chamber, said flap I valve being rigidly secured to the casing, a
