EDWARD F. REYNOLDS, OF -SANTA BARBARA, CALIFORNIA.
eas ENGINE Application led August 13, 1923. Serial No. 657,117.
To aZZ whom it may concern: f
Beit known that I, EDWARD F. REYNOLDS, a citizen of the United States, residing at Sant-a Barbara, in the county of Santa Barbara and State of California, have invented certain new and useful Improvements in Gas Engines, of which the following is a specification.
This invention relates to an internal explosion or combustion engine and more particularly to the two-cycle engine type.
The primary object of the invention is the provision of an internal combustion or explosion engine, wherein the cylinder is provided withtwo oppositely driven pistons connected to the crank shaft so that when a charge is ignited between said pistons increased power will be produced and communicated to said shaft.
Another and very important object of the invention is the production of a two-cycle' engine, having oppositely moving pistons thereln connected to the common crank shaft, said' engine being devoid of head gears or cams, the intake and exhaust ports being opened and closed by the pistons at each revolution.
Another and still important object of the invention is the construction of a two-cycle engine, which is extremely light, highly etlicient in operation, practical, durable, easily assembled, yet permitting the parts to be replaced when so desired and otherwise capable of being manufactured at a very low cost whereby its commercial possibilities are greatly enhanced.
The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming a part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing in the drawing, but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the subject matter being claimed. n
I attain these objects and others in the accompanying drawing, wherein:
Figure 1 is a vertical, longitudinal section through the engine.
Figure 2 is a vertical section taken on the line 2-2 of Fig. 1.
Figure 3 is a section showing the position `of' the piston when the intake port is open; and
Figure 4 is a similar View showing the exhaust port open.
Referrlng now to the drawings wherein like reference characters designate corresponding parts throughout the several views, 5 designates the upper cylinder casing, having an enlarged central portion 6 and base portion 7, to which the crank case 8 is connected in the usual manner. The cylinder proper 9 is provided with an upper piston 10 and a lower piston 1l, between which the combustion chamber 12 may receive an explosive charge to be ignited by suitable ignition means, such as a spark plug insertible in the s ark plug opening 13, as clearly shown by igure 2 otl the drawing. s, f
The upper piston 9 is connected by two connecting'rods 14 to the crank shaft 15, operable 1n suitable bearings 16, and the lower piston 11 is connected by a single connecting rod 17 to the said crank shaft, whereby when a charge of compressed fuel is ignited in the combustion chamber 1, the upper piston moves upwardly and the lower piston moves downwardly, pullingupl and pushing down on the crank shaft 15 and consequently turning thesame. The said connecting rods 1/1 are attached to the bottom art or skirt 18 which acts as a shoulder or compressing the fuel in the fuel mixing chamber 19. The pump compression chamber 19 communicates with` the by-path chambers 20, through the port 22, said chambers holding the fuel and air until it has been admitted into the cylinder or combustion chamber 12 Where it is ignited.
The valves are piston operated, being opened and closed as the sald pistons pass the inlets and exhaust ports. It will be thus observed that the upper piston 10 isv p rovided with horizontal ports 23 and that the walls of the cylinder is correspondingly provided with ports 211, which reglster'with said ports 23 to permit of the exhaust throughthe passage or opening 25 in the casing. Four of such ports are provided in the said piston and cylinder and are con-- compressed air and gas for the scavenger and fuel intake7 which passes through said ports from the remittance chambers 20, 21 and confines the mixture until it has been admitted into the cylinder or combustion chamber 12. The mixing chamber 19 compresses the fuel from the, remittance chambers by means of the piston. portion 18, above referred to, it being observed that a head chamber 30, over the upper piston, admits of the scavenging by the burnt gases `after each explosion, the air being compressed by the piston 11, moving upward which forces the air into the tube or manifold 30a and passes it into a by-path chamber and at the end of the piston stroke it is admitted into the cylinder or combustion chamber 1 through the ports 26, 27, which are opened at this instant. The fuel is taken into the mixing chamber 6 and is compressed up into the chamber 20, as the upper piston moves upwardly, whereupon the ports 32 are opened by the moving piston a few degrees after the ports 34 discharge the compress gas or fuel into the combustion chamber, whereupon the charge is then ready to be compressed by the pistons when they are moved toward each other. this compression takes place the fuel is then ready to be ignited by means of the spark plug in the opening 13, as clearly shown. A cooling chamber 34 is also provided to increase its eciency to perform the functions above set forth.
The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming a part When of this specifications with the understanding, however,` that the invention is not confined to any strict conformity with the showing in the drawing, but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the subject matter being claimed.
Having thus described and illustrated my invention, what I claim as new and desire to secure by Letters Patent is:
In an internal combustion engine of the two-cycle type, a cylinder provided with an enlar ed base portion and an enlarged head cham r, an air and a fuel chamber surroundin the cylinder having ports communicating therewith, a. pair of oppositely disposed pistons reciprocately mounted in l the cylinder, one of the pistons having a skirt for receiving the otherl piston and provided with ports for controlling the entrance of air and fuel into the cylinder through the rts of the air and fuel chambers, a port 1n the fuel chamber communicating with the enlarged base portion of the cylinder, an enlargement formed on the skirt for acting on the fuel in the fuel chamber, a. tube connecting the head chamber with the air chamber, a crank shaft and nlileafrtls connecting the pistons with the crank s a In testimony whereof I ax my signature in presence of two witnesses.
