'OSCILLA'IING GAS-ENGINE.
Specification of Letters Patent.
Application filed January 29, 1913.
Patented Apr. 28, acre.
Serial No. 244,948.
To all 10710171 it may concern Be it known that we, JOHN T. Kniurnn and CHARLES W. KEMPER, citizens of the United States, residing at Garberville, in the county of Humboldt and State of California, have invented new and useful Improvements in Oscillating Gas-Engines, of which the following is a specification.
This invention relates to a gas engine of the oscillating piston type.
The object of this invention is to' corn struct a simple, substantial and practical gas engine which is provided with a single, continuous, circularshaped cylinder in which is mounted a plurality of cooperating oscillating pistons.
Another object of the invention is to construct an engine of this type which will allow the provision of large port areas for the various ports in the cylinder, together with long piston construction and stroke.
A further object of the invention is generally to improve this class of engines so as to increase the. utility, durability and ciliciency.
The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in whieh Figure l is a front elevation of the engine. Fig. 2 is a vertical central section. Fig.3 is across section on line X-X, Fig.1.
Referring to the drawings, A indicates in general a cylinder casting, which is here shown as provided with one continuous circular-shaped cylinder chamber B. In the chamber B are mounted four separate oscillating cooperating pistons 2-, 3, 4 and 5, connected in pairs upon a air of centrally pivoted, oscillating connecting arms or piston-rods 6 and 7. The ends of the connecting arms project through the pistons 4t and a suitable distance and are connected by a pair of connecting rods 8 and 9 with the cranks 10 and ll of a crank-shaft 12. The crankshaft 12 is appropriately joui'naled in bearings 13 and 14 formed in aninclosed crank case 15, to which the cylinder casting is secured, as indicated at 16.
T he lower portion of the cylinder casting A is prorided with inner and outer slots 17 and 18 to allow oscillatory movement of the piston-rods 6 and T, with relation to the pistons l and 5; while the lower side of the between which the several pistons oscillate.
'The chambers 20 and 22 serve the function of explosion chambers, while the chambers 21 and 23 serve the function of compression chambers to charge the explosion chambers. The explosion chambers may be provided with any suitable form of ignition system but is preferably provided, as here shown, with spark plugs 2424, connected in the usual manner to the secondary circuit of a distributer magneto, not here. shown.
The combustion chambers are each provided with radial ports, as 20 and 22, which in turn communicate with exhaust passages 20 and 22 These passages in turn communicate with discharge openings 26 and 27. The explosion chambers are also provided with a series of radially extending inlet ports 28 and 29; the inlet ports 29 communicating through an annular passage 30 and a secondseries of radial ports 31 with the compression chamber 21, while the inlet ports 28 communicate through an annular passage 32 and a similar series of ports 33 with the compression chamber 23. The radial. passages 30 and 32 communicating through the last mentioned ports with the two opposite compression chambers are connected through a manifold 34 with a carburetor of any suitable construction, not here shown. The upper ends of the manifold extensions are provided with check valves 35 and 36 for the purpose of preventing any back pressure on the carbureter.
In operation. it will be seen that oscillatory movement of the several pistons 2, 3, l and 5 in the direction of arrows a will produce a vacuum in the compression chamher. which in turn will be communicated, through the radial ports, annular passages. and manifold. to the carbureter suiiicient suction being produced to open the check valves 35 and 36 to admit a combustible charge into the compression chambers. T he return movement of the pistons will conipress this charge to a suitable pressure; the charge from the conu'ircssiou chamber 21 being transmitted through the radial po s 31, annular passage and the radial ports 29 into the explosion chamber 22, while the charge compressed in the chamber 23 will be transmitted through the radial ports 33, annular 11)assage ;.32, and inlet ports 28 into the explosion cl'iamber 20. The next oscillatory movement of the pistons will admit a new charge into the opposite compression chambers and compress the charge previously admitted into the explosion chambers 20 and 22. This, being ignited through the ignition means, indicated at 2 1 and 24-, will again cause a return oscillatory movement of the various pistons; the burned or expanded charge being exhausted the moment the pistons have assumed aposition where the exhaust passages 20 and 522 are uncoveredv The expanded charge in the combustion chamber 20 will thus escape through the radial exhaust ports 20, annular passage 20 and the outlet 26; while the expanded charge in the chamber 22 escapes through the radial ports 22 annular passage 2% and the outlet 27. The outlets 26 and 27 may be connected in the usual manner with an exhaust pipe, not here shown, and conveyed to any suitable point.
y referring to the central section of Fig. 2, it will be seen that the exhaust ports 20 and 22" are set a little in. advance of the corresponding inlet ports 28 and 29, thereby allowing a complete discharge of the expanded gases to atmospheric pressure he- :tore admitting the fresh compressed charge from the compression chambers which will be admitted through the radial inlet ports 28 and 2-9 the moment exhaust has taken place. The fresh charge entering through the ports 28 and 29 in the opposite ends of the explosion chambers, with relation to the exhaust ports, will help to completely discharge the expanded gases and thus insure uniform and pure mixture. The return movement of the pistons will close the various ports, compress the charge, and correspondingly admit a new charge to the compression chamber. thus repeating the cycle of operation. 'lhe power transmitted tothe several pistons, is transmitted "from the pistons to the connecting rods, which in turn are connected at their lower ends by the connecting rods 8 and 9 with the he of the crank shaft in the usual manner.
l y referring to Fig. 3 of the drawings, it will be seen that the cylinder casting is l divided to provide for the inservarious pistons connecting rods and is suitably secured. together by the bolts 37; the cylinder casting being provider. on its lower side with laterally extending and 39 by which, it may be securi the crank case by bolts 16.
The cons-t uction here shown admits the r provision large and unobstructed port 5.3, Location i areas in the various parts of the cylinders and also makes it possible to provide long pistons together with a long expansion and compression stroke; these points of construction being very advantageous in two cycle engines.
While we have here shown the engine driven by gas on the two cycle principle, it is obvious that the engine is equally opera bio on the four-cycle principle by simply providing a cam shaft and the usual form of valve mechanism. lt is also obvious that the engine may be driven by steam or any other fluid pressure.
The engine is compact and simple in appearance, prompt and reliable in its actions and takes less space than vertical cylinder engines of the same horse power. The materials and finish of the seveal parts of the engine are such as experience and judgment of the manufacturer may dictate.
The underlying idea of the invention involves an arcuate cylinder with one or more arcuate pistons so connected with a crank shaft that the impulses, due to an explosive mixture in the cylinder, will translate the oscillations of the piston or pistons, through a suitable oscillating piston-rod, into continuous rotary motion of the shaft.
Having thus described our invention, What we claim and desire to secure by Letters Patent is 1. tin oscillating piston gas engine comprising in combination, a circular-shaped cylinder casting, an annular, continuous cylinder chamber in said casting, a plurality of oscillating pistons mounted in the cyl' inder, a pair of centrally pivoted oscillating arms to which the pistons are connected, means for supporting a central pivot memher about which the arms and pistons oscillate, radial slots formed in the cylinder casting to permit oscillatory movement of the connecting arms with relation to the pistons, a crank case to which the cylinder casting is secured, a crank shaft iournaled in said case, connecting rods connecting the crank shaft with the piston connecting arms,
means for conducting an explosive mixture to the cylinder, means for igniting the mixture, and means for scavenging the cylinder.
2. in an engine of the class described, the combination of a cylinder casting, a continuous circular cylinder chamber with in said casting, two pair of oppositely-oscillating pistons in said cylinder, pair of pivoted oscillatory arms to which said pistons are connected, meanstor transmitting the oscillating movement oi said arms to a rotary cranl-z-shaft, a pair of compression chambers formed between the ends on one side oit said pistons, a pair of explosion chambers formed between the othe ends of the pistons, exhaust ports leading from said explosion chambers, means for admitting explosive charges to the compression chambers, means for conveying said explosive mixture when compressed to the explosion chambers, and means for igniting said explosive charges in the explosion chambers.
