MANUFACTURING COMPANY, OF CLEVELAND,

Specification of Letters Patent.
Application filed November 12, 19-12. Serial No. 731,000.
To all whom it may concern:
Be it known that I, ALEXANDER WINTON,
a citizen of the United States, residing at Cleveland, in the county of (luyahoga and State of Ohio, have invented certain new and useful Improvements in Oil-Vaporizers for Combustion-Engines, of which the following is a specification, reference being had therein to the accompanying drawing.
This invention relates to improvements in internal combustion engines,'and is of that type which utilizes heavy oils as fuel.
The primary object of my present improvement is to provide the combustion chamber or chambers of an engine of this type with an electrically heated combined fuel vaporizer and igniter for starting the engine, and which after the engine is in operation is caused to perform the function of a vaporizer and ignlter by the actionof the previous combustion and the following compression stroke.
One of the difiiculties with internal cornbustion engines utilizing heavy oils is their tendency to preignition, and a further object of my improvement is to prevent this preignition by taking the air charge into the cylinder independent of the fuel charge and to regulate the time of ignition by the adand as'the time of the admission of the fuel is controlled, this can be made to occur at the proper time in the c cle of the engine to obtain the most eflicient results, and yet absolutely prevent preignition.
In the accompanying drawings-Figure 1 is a vertical section view of an engine cylinder'embodying my invention. Fig. 2 is an enlarged perspective view-ofthe cam operating means for varying the time of the ignition.
Referring now to the drawings, 1 is the cylinder; 2 the piston;,v3 the inlet valve and 4 the exhaust valve, all of which are of the well-known construction and operate in the well-known manner, and need not be further described or illustrated to enable those skilled in this art to understand the invention here sought. to be protected.
My present improvement comprises an electrically heated combined vaporizer and igniter 5, which is laced in the combustion chamber of the cylinder 1. Ashere shown, it comprises a suitable plate. This combined fuel vaporizer and igniter is electrically connected with the poles 6 and 7 of a suitable electrical battery or generator 8, the
'said electrical poles or connections passing through suitable insulated members 9,Wl1l0h pass through the headlO of the cylinder and havlng the connections 6 and 7' with the combined vaporizer and igniter 5. A fuel supply opening 11 is located in the head of the cylinder so that the fuel passing therethrough will strike the heater or combined vaporizer and igniter and be first vapor- 1zed and then the vapor ignited by the incandescent member 5. It will be understood that the electrical generator 8 will be sufficiently powerful to heat the plate or member 5 to incandescence, so that the fuel strlking it is first vaporized and the resultant. vapor ignited. Furthermore, the fuel is a fuel tank 17 having an outlet 18 communithe fuel supply orifice 11 and an air pum 19 connected by a pipe 20 with the tank 1 This air pump is to supply air pressure to the tank 17, so that the liquid fuel therein is placed under pressure. This air-pump 19 may be operatively connected with the engine in any desired manner. For illustrative purposes it is here shown as operated by the stem 21 of the needle-valve 12. It will be understood, of course, that this air-pump will be made of sufficient size to supply the proper amount of air to the tank 1 and that the diameter ofthe pump will. vary according to the length of the stroke, so that the proper and desired eating with Patented July 13, 1915.
amount of air-pressure Wlll be maintained piston reaches its outward movement at the end of the cylinder, the valve 12 is opened and the heavy fuel admitted under pressure which atomizes it as it passes through the orifice 11. The atomized heavy fuel striking the incandescent member 5 is first atomized and the resultant vapor then ignited causing the expansion of the air or gas in the cylinder drivingthe piston outward. After the engine is thoroughly well started and heated up, the combined vaporizer and igniter 5 is kept incandescent by the previous compression and explosion, and the admitted heavy fuel is vaporized and ignited. The connection of the electrical gen-' varying the time of ignition is accomplished by having the cam 14 elongated, as shown in Fig. 2, and longitudinally movable upon the shaft 22. The shaft 22 is provided with a spiral key or feather adapted to enter a corresponding groove in the cam. The outer end of the cam 14 is provided with ,a-peripheral groove 26 into which extends the bifurcated end 25 of the pivoted lever 24. The said lever is held in its adjusted position by the rack 27. By moving the cam through the medium of the lever 24, it will be seen that the same is oscillated on the shaft 22 and in this way varies the period of opening the needle valve in the cycle of the engine. The drawing herein is intended to show only one of. the mechanical expressions of the inventive idea here sought to be protect ed by patent, and I do not therefore limit myself to this single mechanical construction.
The heated head or plate in addition to vaporizing the incoming fuel, heats the incoming air so that this heat plus that of compression raises the temperature to the point where the fuel ignites upon entering the cylinder, after the engine has been running and is normallyheated up. As previously stated in the starting of the engine, the head or plate is initially heated by an electric current.
Having thus described my invention, what I claim and desire to secure by Letters Patent is: l. The combination with an explosion engine having an exhaust port and an air inlet port, engine operated valves for said ports,
'an electrically heated oil vaporizer Within the combustion chamber of the engine cylinder, an oil supply, means operated by the engine formaintaining the oil supply under pressure, an oil outlet orifice adapted to de liver the oil against the vaporizer, an en-* gine operated oil controlling valve for said oil orifice, andan adjustable means for, varymg the t1me of operation of the engine controlled oil valve all combined for the purpose described.
v 2. The combination with an explosive engine having an exhaust port and an air-inlet port, engine-operated valves for said ports, a combined electrically heated oil vaporizer and igniter within the combustion.
- said oil orifice, and an adjustable means for Varying the time of operation of the oil controlled valve all combined for the purpose described.
3. The combination with an internal combustion engine having exhaust and inlet ports, engine operated valves for said ports, a, combined vaporizer and igniter within the combustion-chamber of the engine cylinder, an oil tank adjacent the cylinder, a pipe leading from the oil tank to the cylinder above the vaporizer, a reciprocating valve controlling the oil-supply to the engine cylinder, means operated by the engine controlling the said valve, and a pump operated by the said valve for compressing the air in the tank for the purpose described. In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
