I VAPOR ATTACHMENT FOR EXPLOSIVE-ENGIN'ES.

tarmac.

To all whom it may coneem:

Be it known that I, GEORGE M. WA'i'rnns, a citizen of the United States, residing at Minneapolis, in thecounty of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Vapor Attachments for Explosive-Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention has for its object to provide an improved device for supplying water vapor with the explosive mixture to internal combustion engines; and to such ends, generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claim. v I

Theinvention is illustrated in the accompanying drawings, wherein like characters lndicate like parts throughout the several views. Referring to the drawings:

Figure l is a side elevation showing the improved.vaporizer applied toan explosii e engine; I

Fig.- 2 is a vertical section of the water trap of the vaporizer;

Fig. 3 is a detail in section on the line 3-3 of Fig. 2; and I Fig. 4 is a side elevation of the vapor-supplying valve.

In Fig. 1, the engine .is indicated, as an entirety, by the numeral 5, its intake manifold by the numeral 6 and the carbureter by the numeral 7. The numeral 8 indicates a radiator of the usual arrangement having an overflow pipe 9 of the customary arrangement. The instrument board ofthe auton'iobile is indicated byfthe numeral 10. In the application of my invention, I tap the overflow pipe 9 by a vaportube 11, and

this vapor tube is extended down-into thea irtight shell 12 of a water trap or separator for separating the vaporfrom condensed water. .This shell 12, which is preferably 'in the form of a cylindrical drum "having closed heads, is preferably provided with two horizontal partitions 13'f0rmed of very fine mesh, wire screen, preferably about 80 inesh. The lower end of the vapor tube 11 terminates above the bottom of the tank but below the lower screen 1 3. Between the two screens 13, the vapor pipe 11 is cut away, at least in part, and the opening iscovered by type, which latter opens Specification of Letters Patent.- P t t t, .3, 1913, Application filed September 30, 1916. Serial No. 123,023.. I i

a fine mesh tubular screen 14. The top of the drum 12 is connected by a vapor tube 15 to a vapor supply valve of the petcock directly. into the This valve coma tapered rotary fuel intake manifold 6. prises. a casing 16 and valve 17, the latter having a depending arm.

18 connected to the front end of an operat ing' rod 19,.the said rod being preferably extended through and terminating in a knob by means of which said valve may be freely moved to and from 'closed position.

In the bottom of the drum 12 is a drain port 21 that is normally closedby a lightly within the tank whenever the altitude of the water nearly reaches the lower end ofthe vapor tube 11, and in this way, automatically maintains an amount of water in the drum substantially as shown in Fig. 2.

My improved device supplies both air and water vapor but no solid water to the manifold ofthe engine for admixture with the hydrocarbon 'vap'or. In the first place, only vapor will be drawn from the top ofthe radiator; and in the second place, any water which condenses in the pipe 11 and drum 12 will be precipitated to the bottom' of the drum. Some of the vapor -will escape through the tubular screen 14, and from thence will pass upward through the upper screen 13 and to the engine through thevapor tube 15, butsome will pass out of the lower end of the said tube 11 and hence, if it is to reach the engine, must pass upward through both of the screens 13. T ese two screens positively insure condense water from reaching the tube 15.

In practice, the device has been foundeflicient for the purposes had in view. The water vapor afi'ords' suflicient dampness to remove carbon and keepthe spark plugs and firingchambers free of carbon. It also renders the explosive mixture more efiicient and thus effects a saving in the use of gasolene or automobile fuel.

What I claim is:

A water vapor supply device for explosive engines including a closed drum having therein fine screen partitions, one above the other dividing the drum into upper, intermediate and lower chambers, a vapor tube delivering into said drum at a point be spring pressed drain valve 22 mounted in a housing 23 secured tothe bottom of said drum. Thetension on this valve 22 is such tween said screens andnvapor tube leading In testimony whereof I afilx my signature from said cil irum at 2:1 point abogre 1:118 upper in presence of two Witnesses.
