GAS-ENGINE.

To all whom it "LII/:1] concern:

Be it known that I, RICHMOND LEVERING, a citizen of the United States, residingat the city, county, and State of New York, haveinvented certain new and useful Im rovements in Gas-Engines, of which the f0 owing is a full, clear, and exact description.

My invention relates to mprovements in gas engines, and involves the method of providing and sup lying to the engine a suitable gas for internafcombustion. 1

Heretofore only the more volatile hydro- I carbons have been employed for this purpose with any degree of satisfaction in general practice.-' By my invention, however, kerosene or crude oil, for example, may beem-v ployed with entire satisfaction with greater elliciency and relatively less expense;

In the accompanying drawings I have shownconventionall-y my invention as applied to a four cylinder engine of the internal combustion type.

In said drawings Figure 1 is a diagrammatic view; partly in elevationand partly in section. Fig. l is a relatively enlarged. view of details of construction, partly in section on the line X.X Fig. 1. Fig. 3 is a relatively enlarged sectional view on the plane of the line YY Fig. 1.

1 111 represent four cylinders, the

I same being shown conventionally.

2 is a supply pipe having suitable branches leading to each cylinder.

3 represents an exhaust pipe incommon to all the cylinders.

4 is a gas forming chamber directly adjacent to the exhaust ipe 3, and partitioned therefrom by the wal 5.

6 is a pipe arranged to convey liquid fuel from .the tank or receiver K, which receiver may contain a suitable liquid fuel, for example kerosene. Projecting from the fuel supply pipe 6 into the gas forming chamber 4 are spraying nozzles 7 in any suitable numher. One of these nozzles is shown inFig. 2. In the particular construction shown in the drawing, it would be referable to-have four. nozzles, locating one irectly in front of each exhaust outlet from the several cylinders. As is well known, the hottest part of" the exhaust pipe is directly where the exhaust gases emerge from the cylinder, and the greater efficiency can be obtained byhaving the spraying nozzles 7 so placed as to roject any spray therefrom directly against t e wall of the exg haust pipe 5 where the same is the'hottest.

endand leads in a direction preferably to follow the exhaust pipe fora considerable distance. When fuel is forced through ipe 6, it emerges in a fine stream through t e several nozzles 7. Upon encountering the hot wall 5 expansion takes place'and it is converted into gas. I

8 is a gas receiver or tank connected to the gas forming chamber 4 bv a cooler 9 in which is located a suitable check valve 10. The increase of pressure within the. gas forming chamber 4 will cause the gas therein to be forced past the check valve 10, through cooler 9 and into storage tank 8. When a sufficient uantity of gas has been stored in tank 8, and t 1e pressure therein has risen to a predetermined point, a valve 11. will be forced open so that any excess pressure will be revented.

The gas forming chamber 4 is closed at one On the stem of this valve 11 may e another 16 represents a gas ipe having a valve 16*" therein, and leading rom tank 8 to a mixer conventionally shown, at M and of any desired form.

17 is a pipe having a valve 17 therein. This pipe 17 is adapted to convey the mixture formed within the mixer M to the pipe 2.

O conventionally represents a carbureter.

G represents a tank containing, for example, gasolene or naphtha.

18 is a pipe, having a valve 18 therein, leading from the tank G to the carbureter C.

19 is a pipe leading from the carbureter C to the supply pipe 2. 19 is a valve therein. The liquid gasolene is, conveyed through pipe 18- to the carbureter C, where it is mixed in any suitable way with the proper proportion of air to form an explosive mixture. This mixture is then'conveyed through pipe 19 to the supply pipe 2.

In operation the engine is started, for example, by means of gasolene. The valves 18 and 19 being opened to the proper deree, while the valves 16* and 17 are-closed.

cient time to p'roperlyheat the exhaust, the

valve 14 is opened, whereupon the fuel fromthe tank K is forced into the chamber 4 where the gas is formed in the manner previously described. While the gas is in the chamber 4 (which is preferably continuous down to the check valve 10) it becomes an This gas passes through the cooler 9 and into the receiving tank 8. When a sufficient quantity of gas is contained therein, the valves 18 and 19 may be closed and the valves 16 and 17 ber adjacent to said exhaust but not in communication therewith, a fuel supply leading to the. interior of said gas forming chamber, a gas storage reservoir connected to said gas forming chamber, a check valve between said reservoir and chamber,.a connection leading from said storage reservoir to said cylinder, and a mixer in said connection.

2. In an engine of the internal combustion type, a cylinder, an exhaust pipe leading therefrom, a gas forming chamber adjacent to said pipe but not in communication there with, a liquid fuel supply leading into said chamber, a gas receptacle, a gas cooler between said gas forming chamber and said receptacle and connecting the same, a check valve between said reservoir and chamber, a connection from said reservoir to said engine, and an air and gas mixer in said connection.

3. In an engine of the internal combustion type, a cylinder, an exhaust, a gas forming chamber, a gas cooler, a gas receiving tank,

a connection from said tank to said cylinder,

an air and gas mixer therein, a liquid fuel supply leading to said gas forming chamber, a valve therein, an outlet from said gas receiver, and a pressure controlling valve therein.
