543,163	Jul. 23, 1895	Explosive Engine	Carl W. Weiss	Brooklyn, Kings County, NY	Abstract: This invention relates to the general class of gas-engines, and particularly to gas-engines, of that type in which the charge is compressed in the motor-cylinder before ignition. The increased efficiency of engines of this type over those in which there is no compression of the charge is Well known, and theoretically the efficiency should increase with increased compression. It has been generally held, however, that the practical limit in this-direction has been reached because, with the increase in bulk and Weight of parts supposed to be required by the greater strains attending increase of compression the friction of the moving parts and consequently the negative work of the engine increase more rapidly than the efficiency. On the other hand, investigation has shown that it might be possible to prevent the relatively rapid increase of negative work above alluded to and thereby to obtain, in part at least, the theoretical advantage due to an increase of compression. In the present engine the forward movement of the piston is made against the resistance of an elastic medium which is interposed between the piston or some part connected therewith and a suitable rigid land unyielding abutment whereby the strains upon the moving parts, such as the thrust upon the crank and the friction on the cross-head or slide are relieved, and the energy which is stored in the medium by the forward stroke of the piston is imparted again to the piston on its return stroke. The desired effect is most conveniently and effectively secured by maintaining a constant fluid pressure, above atmospheric pressure against the front side of the piston, for which purpose the front end of the motor-cylinder is formed with or communicates with a closed chamber filled with gas or air. The pressure within the chamber is practically constant (assuming the piston to be at rest) and the best results will be obtained when it is somewhat greater than the pressure upon the compressed charge. A further important result is secured by causing the pressure to be exerted upon the front end of the piston within the cylinder, in that the tendency to leakage between the piston and the walls of the cylinder is reduced to an extent corresponding to the degree of the pressure in the front end of the cylinder. Claims: 1. In a gas engine, the combination of a motor cylinder, a second or pump cylinder in line with the first, pistons in said cylinders connected to move together and a conductor through which the charge is forced from the pressure chamber of the pump cylinder and is delivered into the motor cylinder through the motor piston, substantially as shown and described. 2. In a gas engine, the combination of a motor cylinder, a piston having a port therein, a hollow piston rod, a second cylinder in line with the first, a second piston fixed to said rod and adapted to move in said second cylinder, said hollow rod having inlet ports in advance of the second piston, and a chamber communicating with the forward end of the second cylinder and having an inwardly opening port, substantially as shown and described. 3. In a gas engine, the combination of a motor cylinder, a piston having a port therein, a chamber communicating with the enclosed space in front of the piston and tightly closed to prevent reduction of pressure by escape of its contents, a second cylinder in line with the first, a second piston connected to the first and adapted to move in said second cylinder, said pistons being connected by a conductor having inlet ports, and an inwardly opening valve to permit the admission of gas to said second cylinder, substantially as shown and described. 4. In a gas engine, the combination of a cylinder having an exhaust port at its rear end and having its forward end tightly closed, a hollow piston rod passed through the front end of said cylinder, a piston in said cylinder perforations communicating with said port whereby the incoming charge is evenly distributed, and means to introduce the charge into the hollow piston rod, substantially as shown and described. 5. In a gas engine, the combination of a cylinder, a piston therein, said piston having a single port formed through it and said single port having two valve-seats formed in its f walls, a valve plug adapted to rest upon the innermost seat and an independent valve plug having a stem entered in `and guided by the first valve plug and adapted to rest upon the second valve-seat, both of said valve plugs opening in the same direction, substantially as shown and described. 6. In a gas engine, the combination of a cylinder, a piston therein, said piston having a single port formed through it and said single port having two seats formed in its walls, and a two-part valve in said port, one part independent of and covering the other, and opening in the same direction, and each part adapted to close said single port, substantially as shown and described. 7. The combination of a motor cylinder, a piston having a port therein, an independent pump cylinder, means to conduct the charge from the pump cylinder to the port in the piston, and wire gauze interposed between the port and the conductor to prevent lighting back, substantially as shown and described 8. In a gas engine, the combination of a motor cylinder having at its end behind the piston an exhaust port for the burned gases, a tightly closed compression chamber communicating with the front end of said cylinder, and a pump cylinder communicating with the space behind the motor-piston for the delivery of the explosive charge thereto, whereby a fresh charge may be delivered under pressure to the motor-cylinder without necessitating openings through the wall of the motor-cylinder, which would reduce by leakage, the efficiency of the compression chamber, substantially as shown and described.

592,034	Oct. 19, 1897	Explosive Engine	Carl W. Weiss	New York, NY
704,995	Jul. 15, 1902	Explosive Engine	Carl W. Weiss	New York, NY	Abstract: This invention relates to the general class of explosive-engines in which the explosive mixture is formed in the working cylinder or explosion-chamber, a liquid hydrocarbon or a previously-formed gas being introduced into such cylinder or chamber and there mixed with air. One object of the invention is to provide for the reduction of the temperature of the explosion chamber, and consequently of the fresh charge as it is introduced, so that a higher degree of compression can be reached without ignition and the efficiency of the engine increased. A further object is to provide for at thorough clearing out of the dead gases from the explosion-chamber after each explosion. A further object, particularly applicable to engines of this class with which a previously formed gas is made the basis of the explosive mixture, is to guard against the retention of any explosive mixture in the ports or passages leading to the explosion-chamber, such retention of explosive mixture leading to secondary explosions, which, at least, impair the efficiency of the engine, if they do not cause injury to its working parts. To effect the cooling of the explosion-chamber and the clearing out of the dead gases, a small quantity of Water is introduced into the explosion-chamber in advance of the formation therein of the explosive mixture, the water so introduced being instantly vaporized, absorbing heat and driving out the dead gases which then remain in the chamber. The relative time at which the water is introduced is of the essence of this part of the invention. It has been proposed heretofore to introduce a small quantity of water into the explosion-chambers of engines of this class at or immediately after the instant of ignition, with the idea of utilizing the expansive force of the steam thus generated for power behind the moving piston. Incidentally the vaporization of the water would reduce the temperature within they cylinder; but such reduction reducing the efficiency of the mixture than would the dead gases which have been expelled by it. It will be evident that this part, of the invention is not limited to any particular form of engine or of devices with which it is practiced. Claims: l. In an explosive-engine, the combination with an explosion chamber or cylinder having a supply-port and an exhaust-port opened as the piston approaches the limit of its forward stroke, of means to introduce Water into the chamber or cylinder as said ports open, whereby the water precedes the explosive charge. 2. In an explosive-engine, the combination with a cylinder having supply and exhaust ports opened by the piston as it approaches the forward limit of its stroke, and means to discharge water through said supply-port as it opens. 3. An explosion-engine having independent air and gas supply ports terminating in the inner surface of the cylinder-Wall and means to close said ports at their extremities. 4. An explosive-engine having independent air and gas supply ports terminating separately in the inner surface of the cylinder-wall and uncovered by the piston in its forward movement.
708,284	Sep. 02, 1902	Incandescent Igniter for Explosive Engines	Carl W. Weiss	New York, NY	Abstract: This invention relates to explosive engines in which a non-gaseous fuel .is employed as the basis of the explosive charge; and it has for its object to provide improved means for the simultaneous ignition of the charge at different points in the cross-section of the working cylinder or explosion-chamber. Claims: 1. In an explosive-engine, the combination of a combustion chamber or cylinder, a plurality of separate and independent igniters disposed on the cylinder-head at widely-separated points to ignite the charge at different places in the combustion-chamber simultaneously, one or more of said igniters having a projection within the cylinder, and means to inject the fuel against such projection, substantially as described. 2. In an explosive-engine, the combination of a single combustion-chamber, a fuel-supply pipe having a nozzle with a plurality of inlet-openings, a plurality of separate and independent igniters disposed on the cylinder-head at widely-separated points within said single chamber to ignite the charge at different places in said chamber simultaneously, the igniters in line with said inlet-openings being provided with lips to receive and vaporize the fuel, substantially as described.
710,026	Sep. 30, 1902	Lubricator for Explosive Engines	Carl W. Weiss	New York, NY	Abstract: This invention relates to devices for delivering lubricating-oil to the pistons and other enclosed parts of explosive-engines. Heretofore such devices have generally been so constructed and arranged that it has been impossible to determine with certainty whether the lubricating-oil is being properly fed. Even when sight-glasses are provided it has often happened that the oil-passages, including the passage through the sight-glass, have been filled with oil, so that the escape of oil from the needle or other valve drop by drop cannot be seen. It is the object of this invention to provide such a construction so that the accumulation of oil is prevented and the dropping of the oil from the needle or other valve can be seen at all times.

710,824	Oct. 07, 1902	Incandescent Igniter for Explosive Engines	Carl W. Weiss	New York, NY	Abstract: This invention is particularly concerned with the ignition of the explosive charge in internal-combustion or explosive engines, and has for its object to provide an improved igniter which shall retain the heat sufficiently to ignite a charge at the beginning of every cycle of the engine, although the character of the explosive mixture may vary and although the walls of the explosion-chamber are kept at a temperature sufficiently low to avoid premature ignition of the charge, even under high compression. A further object is to provide an igniter, which will not become filled with carbon and will itself give long service. Claims: 1. In an explosive-engine, the combination with a tubular extension or shell extended rearwardly from the cylinder-head, of an independent, tubular igniting ignition-tube, open at its forward end only, placed loosely within said shell or extension, substantially as described. 2. In an explosive-engine, the combination with a tubular extension or shell, extended rearwardly from the cylinder-head, of an independent, tubular igniting ignition-tube having a relatively large bore with a restricted port at its forward end, placed loosely within said shell or extension, substantially as described. 3. In an explosive-engine, the combination with a tubular extension or shell, extended rearwardly from the cylinder-head, of an independent, tubular igniting ignition-tube, open at its forward end only, placed loosely within said shell or extension, and a bushing secured in the forward end of the bore of said shell and independent of said ignition-tube, substantially as described. a. In an explosive-engine, the combination with a dash-plate secured to the cylinder-head, a tubular extension or shell extended rearwardly from the cylinder-head and means to discharge oil upon said dash-plate, of an independent tubular igniting ignition-tube, open at its forward end only, placed within said shell or extension, substantially as described.
723,956	Mar. 31, 1903	Explosive Engine	Carl W. Weiss	New York, NY	Abstract: This invention relates to various features of construction, and has for its general object the production of an explosive-engine of exceedingly simple construction, but of great efficiency and capable of very high speed. One feature of the invention is concerned particularly with the introduction of the oil, which forms the basis of the explosive mixture, the vaporization of the oil, and the mixture of such vapor with air to form the explosive mixture, the special object in view being the certain vaporization of the oil without raising the temperature of the cylinder unduly and the speedy circulation of the vapor throughout the explosion-space in the working cylinder and the consequent reduction of an explosive mixture of uniform quality throughout the explosion-space, whereby f the best results as to efficiency and economy are produced. Claims: 1. In an explosive-engine, the combination with a cylinder and piston, a cylinder-head having a substantially plane face, a tubular igniter carried by the cylinder-head, a compression-chamber in front of the piston and an air-duct from said compression-chamber having a port opened by the piston at the forward limit of its stroke, said cylinder having an exhaust-port also opened by the piston at the forward limit of its stroke, of an oil injector located in the wall of the cylinder, a separate dash-plate secured on the cylinder-head within the cylinder against which the oil is discharged by the injector, and means to direct the current of air from the port when opened upon said dash-plate, whereby the dash-plate is maintained at a vaporizing temperature and the vapor is carried away from said dash plate as formed and made to circulate in the cylinder and is thoroughly mixed with air. 2. In an explosive-engine, the combination with a cylinder and piston, a tubular igniter carried by the cylinder-head, a compression-chamber in front of the piston and an air-duct from said compression-chamber having a port opened by the piston at the forward limit of its stroke, said cylinder having an exhaust-port also opened by the piston at the forward limit of its stroke, of an oil-injector located in the wall of the cylinder, a separate dash-plate secured on the cylinder-head within the cylinder and between the igniter and the injector, and means to direct the current of air from the port when opened upon said dash-plate.
908,527	Jan. 05, 1909	Internal Combustion Engine	Carl W. Weiss	New York, NY	Abstract: This invention relates to the introduction into the working cylinder or explosion chamber of the air which, with the fuel, forms therein the explosive mixture and in accordance with the invention the exhaust from the cylinder or explosion chamber is made to act by induction or aspiration upon a body of fresh air so as to place the same in position to be drawn into the cylinder or explosion chamber through the exhaust opening as the pressure in the cylinder or chamber falls below atmospheric after the expulsion of the dead gases. When the exhaust port is opened, either by being uncovered by the piston in its movement or by being opened through suitable mechanism actuated from some moving part of the engine, the dead gases immediately escape with a high temperature and with such a high velocity that if the gases are directed through a suitable inductor or aspirator a flow of fresh air will be induced from a the charge may be introduced in any convenient and suitable manner, either with the air or independently thereof. Incidental to the introduction of the air in this manner, the number of necessary ports in the cylinder is reduced to one and, furthermore, the noise of the exhaust is largely reduced. It will be obvious that the form of the devices employed for the introduction of the air in the manner described may be varied and that such devices may also be connected differently to the cylinder or chamber, all as may be rendered desirable by the particular conditions of use. Claims: 1. An internal combustion engine having an air inductor applied to the exhaust port, whereby the escaping exhaust gases induce the flow of a body of air which is drawn into the cylinder or chamber through the exhaust port as the pressure therein falls. 2. In an internal combustion engine, the combination with a cylinder or chamber having an exhaust port, of an inductor or aspirator applied to the exhaust port and provided with an air inlet and an extension, whereby the escape of the exhaust gases induces a flow of air into the inductor or aspirator and the air is drawn into the cylinder or chamber through the exhaust port as the pressure therein falls.
