To @ZZ whom it may concern:
Be itknown that I, FRANZ BURGER, a citizen of the United States, residing at Fort Vayne, in the county of Allen and State of Indiana, have invented certain new and useful Improvements in Gas-Engines, of which the following is a specification.
My invention relates to gas-engines, especially to those in which the gas is burned with slow-combustion or internal-combustion engines, and some of the features of which are adapted to be used in connection with explosive-engines; and my invention consists in means whereby to properly combine the air and gas at the time of burning and secure a compressed volume of air without mixing the same with the products of combustion, as fully set forth hereinafter and as illustrated in the accompanying drawings, in which- Figure l is a side elevation with the cylinder and its mechanism in section. Fig. 2 is a plan View with the cylinder in section. Fig. 3 is an enlarged sectional view through the compressing-chamber. Fig. 4 is an enlarged transverse view of the compressing-chamber at the point where the chamber joins the cylinder, and Fig. 5 is an enlarged sectional side view of the fuel-compressing valve located on the fuel-supply pump.
The cylinder W is jacketed, preferably, throughout its length, including the head, and contains the piston K, connected in any usual or suitable manner with the crank of the shaft O. The piston does not travel the entire length of the cylinder, so that when in its rear position there is left a chamber a, and into this chamber air is drawn through a port closed by a self-seating valve D when the piston K moves outward, the air being compressed in the chamber on the back movement of the piston. At the forward portion of the chamber a is an exhaust-port closed by a valve E, opening forward and closing under the action of a spring, and which is positively opened on the backward movement of the piston K after an explosion, so that the products of combustion are forced out through the said port and through an exhaust-port F Without mixing with the contents of the chamber a at the rear of the port closed by the valve E. The gas is admitted through a nozzle I, arranged at such a point that the gas Hows into the cylinder in advance of the chamber c, so that the compressed air will tend to flow forcentral port L opposite the nozzle I, the said port being formed in a nipple and expanding toward the forward end and also toward the rear around the nozzle, so that the entering jet of gas tends to draw the air from the chamber a into and project it through the port. The partition() serves to preserve the purity of the air charge and maintain it separate from the gases within the cylinder and further serves to close the portion of the cylinder in which the piston reciprocates, and being arranged at the rear of the line of division between the front and rear portions of the cylinder the removal of the latter carries with it all of the ports and valve appliances described, leaving the forward portion of the cylinder accessible for purposes of repacking the piston, 85e. The rear removable portion B is provided with a water-jacket which connects with that upon the forward portion, so that the water will tend to preserve the comparatively low temperature of the air within the chamber a, securing the oxygen in amore condensed form. The gas is forced into the nozzle I through the medium of a pump I), operated from an eccentric Q on the shaft O, and this pump forces the gas through a suitable pipe R, provided with a check-valve casing S, to a reservoir T, from which it passes through a pipe U to the nozzle I, the pipe U being provided with avalve atV, which valve is operated to admit the gas at the proper time through the medium of an eccentric m on a gear-wheel l, driven by a small gearwheel 2 on the shaft O, as shown in Fig. 2.
A relief-valve 3 is provided which will prevent the pressure in the reservoir T exceeding any predetermined degree. By this means it is possible to secure a uniform action of the gas, so that it will afford the desired burning mixture without being either so low in gas as to produce an explosive mixture or so high as to burn improperly. The relief-valve may be arranged at any proper point; but as shown in Fig. 5 it is arranged to close a port in the check-valve 4, the said relief-valve 3 being IOO secured to a stem which passes through ayoke 6 on the valve 4 and is lifted by a spring 5, coniined by a nut which may be adjusted to secure any desired pressure.
Any suitable governor may be arranged to control the flow of gas in any of the usual ways; butit is apparent that there will not be that variation in the pressure which results when a pressure-tank and means for maintaining a uniform pressure are provided.
The exhaust-valve is opened by a lever 7 and rod 8, connecting with a cam-lever l0, which receives its motion from a cam 9 on the gear-wheel l.
By providing a compression-chamber directly in the cylinder instead of outside of the same, as has sometimes been done, Isecure a more compact structure. avoid the necessity of joints and connections, and preserve the air at the proper temperature.
The operation of the apparatus will be largely understood from what has been stated above, and, briefly, it is as follows: The engine is a four-cycle engine, and on starting from the position shown inv Fig. l, the piston moving toward the right, air is drawn into the cylinder through the chamber a and valve Y'1), and on the return stroke the air is compressed into the clearance or compressing chamber a. At the next outstroke `the gas or fuel under pressure flows through the nozzle I and conical aperture L, thereby mixing with the outrushing compressed air, and is ignited by the igniter G. The mixture will burn continuously without explosion in the cylinder, driving the piston ahead by the expansion-of the air produced by the burning fuel. When the piston has reached the extreme of its outstroke, the exhaust-valve E is opened, and the products of combustion are expelled by the return of .the piston to its normal position.
l The supply-pump is worked from the main engine-shaft, supplying the reservoir continuously with fuel, which is kept under a practically uniform pressure.
It will be seen that the compressing-chamber A contains. nothing but air and that the products of combustion are not mingled with air, but remain in the cylinder until the piston drives them through the exhaust-port.
While in the form shown the engine works on the four-cycle principle, it is obvious that my invention can be used on other cycle engines.
Without limiting myself to the precise construction and arrangement of parts shown, what I claim isl. The combination in an internal-combustion engine, of a cylinder having atransverse partition forming a chamber at the rear of the cylinder, a port in said partition, means for introducing air into said chamber and for compressing the same, a gas-nozzle for delivering gas 'through said port, and an igniter in said port, substantially as described.

The combination in an internal-combustion engine, of a cylinder havinga transverse partition near the rear end forming an airchamber, a water-jacket surrounding the cylinder throughout its length, a nipple in said partition forming a port between the chamber and cylinder, means for introducing air into the chamber, and means for injecting gas through said port and means for igniting the same in its passage through the port, substantially as described.
5. The combination of a cylinder having a surrounding water-jacket and divided into two sections, the rear section having a transverse partition with a port therein, with means for introducing air into the chamber back of the partition, means for delivering gas through said port into the cylinder, and means for igniting the gas in its passage through the port, substantially .as described.

The combination of a cylinder having a surrounding water-jacket and divided into two sections, the rear section having a transverse partition with a port therein, with means for introducing air into the chamber back of the partition, means for delivering gas through said port into the cylinder, means for igniting the gas in its passage through the port, and a IOO IIO
channel extending through the rear portion and provided with an exhaust-port and valve, substantially as described.
7. A cylinder havinga transverse partition forming an air-chamber at its rear end an open port in said'partition for the passage of air from the chamber to the cylinder, an airnlet port for said chamber, a valve in said inlet-port, an exhaust-port in said partition communicating with an exhaust-channel outside of said air-chamber, and a valve for controlling said exhaust-port, substantially as set forth. Y
