GAS-ENGINE.
SPECIFICATION forming part of Letters Patent No. 767,369, dated. August 9, 1904.
Application filed October 12, 1903. Serial No. 176,682. (No model.)
To all whom it may concern:
Be it known that I, PETER SoHMI'rZ, a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Gas-Engines, of which the following, taken in connection with the drawings, is a specification.
This invention relates to gas-engines of the type known as two-cycle engines. It is designed to receive an impulse for each revolution of the crank-shaft and to apply the resultant force to said shaft, which may be considered a main shaft.
In carrying out said invention I have provided a reciprocating compression-cylinder divided into two chambers, one purely for compression and the other for compression and combustion, by a central piston fixed relatively thereto and working in connection with two fixed cylinders having abutments and water-chambers, over. which latter cylinders the chambers of the compression-cylinder telescopes. Valve connections and inlet and exhaust ports are provided, whereby the expansion of the ignited gases in the combustion-chamber causes compression of gas in the opposite chamber, which is then led into the exhausted combustion-chamber and then. further compressed in the reverse stroke and ignited at the termination of said stroke, which corresponds with the completion of one revolution of the crank-shaft.
Other novel features of the invention will appear in the accompanying description and by reference to the accompanying drawings, in which- Figure 1 represents a central sectional view in top plan of a machine embodying said invention in its preferred form. Fig. 2 is a side elevation of said machine in longitudinal central section. Fig. 3 is across-section thereof on the correspondingly-numbered line in the preceding figure, and Fig. 4 is a similar crosssection on the line 4 4 of Fig. 2.
Referring to said drawings, A represents the casing of the machine fixedly supported on legs A or in any other desirable manner.
B is the crank-shaft turning in bearings b, secured to the rear end of the casing or otherwise. The casing is advisedly made cylindrical throughout its length, except toward the rear, where it begins to flare from lugs 0 to the end to accommodate the play of the forked pitman C or connecting-rod for the piston. It has also lateral bulges C for the latter purpose. To the lugs 0 is bolted the flange d of a cylinder D, concentric with the casing and divided by diaphragm d into the compartments or chambers D D, the former or forward one of which is open and forms part of the combustion-chamber, while the rearmost, D is filled with water, also closed by a cap (Z2 to confine its charge. Packingrings (Z3 are inserted in channels in the forward periphery of this cylinder, hereinafter termed the rear fixed cylinder.
To an insetting-rim at the front of the casing is bolted the flange c of a second or forward concentric fixed cylinder E, likewise divided by a diaphragm or abutment (2 into two chambers or compartments E and E the former, in this instance the rearmost one, being open and constituting part of the primary compressing-chamber, and the latter or frontchamber being filled with water and closed by cap (Z to confine the contents. Like the rear fixed cylinder, the forward one has exterior packing-rings 6 set in peripheral channels, but at its rear end. The cap and abutment of the cylinder E are both penetrated. by inlet-pipe F, leading from a suitable chamber and opening into the primary compressingchamber to deliver the motive fluid thereto. A check-Valvef in this pipe permits the inflow of the charge through the pipe, but cuts off its exit thereby.
Closely fitting over and playing upon the two fixed cylinders is a piston-cylinder Gr, divided by piston 9 into two chambers G and G the chamber G constituting, with the piston and the new chamber and abutment of the front fixed cylinder, the primary compressionchamber, and the chamber Gr constituting, with the piston, the front chamber, and abutment of the rear fixed cylinder, the secondary compressing and combustion chamber.
The pitman, as above stated, is forked, its arms h 71/ passing one on each side of the piston-cylinder between the latter and the easing and being journaled upon the ends of a rod H, passing through the piston.
Formed in the wall of the piston-cylinder is an exhaust-passage 1, extending longitudinally thereof and having ports 11 2", which in the position of parts indicated in Fig. 2 are both closed by the walls of the fixed cylinders; but when the piston-cylinder moves farther to the left under the force of the expanding gases in the explosion-chamber are caused to register, the first with exhaust-port I and the second. with said chamber, thus opening a passage-way for the dead charge.
Through the wall of the compressing-chamber of the piston-cylinder is found an eduction-port k, which at a certain point in the reciprocation of said cylinder registers with a passage-way Z/ in valve-box K, being at other times out off by the close-fitting contact of the external surface of the cylinder with the contacting planed surface of the valve-box. A cheek-valve K permits the passage of the charge from the compression-chamber into the passage Zr, but prevents its return. From the passage Zr a port Z leads through the valve-box in such position that at the moment port /r and. passage A" are in registry the port d registers with the port Z, leading into the explosion chamber, being at other times cut olf by the closing of the outer Wall of the reciprocating-cylinder t'herepast.
In operation the piston-cylinder is moved to the left by the energy of the exploded gases compressing the gas in the left-hand or compression cylinder until the port '2 opens to the explosion-chan'iber, when the latter is at once exhausted by the concurrent registry of the port 2" and the exhaust-port I. This takes place at the moment the crank is passing the inner dead-center. In its further movement the ports k and Z are opened to the passage 7: and the combustion-chamber receives a fresh charge, which is compressed. therein until the crank passes the outer dead-center, when ignition takes place, and the piston moves again to the left.
I claim The combination of the two fixed cylinders and their abutments dividing them into watercompartments and compression and combustion chambers, the pistoncylinder playing over said fixed cylinders and divided by the piston into cooperating compression and combustion chambers, a valved inlet for the motive fluid delivering to the combustion-chamher, a passage-way and check-valve, ports in the respective sections of the piston-cylinder which register with the respective ends of the said passage-way at determined intervals, the forked conneetingrod and a crank-shaft operated thereby, an exhaust-port in one of said fixed cylinders and an exhaust-passage in the piston cylinder opened to the combustionchamber and to said port at the end of the forward stroke thereof, substantially as described.
