I Application filed Se ptcmbcr 22, 1922 serial' l o'i58a84.

This invention relates to. internal. combus- 1 tion engines, the generalrobjzect of the invenengine can be. operated on'gas fuel instead 6 air intake of the carbureter.

of liquid fuel with but littl'e change to the engine parts. 7

.Another objectfof'the invention isto so "arrange the parts of the invention that the engine can be run on liquid fuel whenever desired and without removing the gas feeding mechanism.

A further object of the invention is to provide a tank for holding natural gas with means for mixing the same with the airand introducing the mixture into the air intake of the carbureter of the engine.

This invention also consists in certain other features of construction and'in the combination and arrangement ofthe several parts, to be hereinafter fully described; illustrated in the accompanying drawings and specifically pointed out in the appended claim. f' In describing my invention in detail, reference will be-had-to'the' acompanying draw-' ings .wherein like characters denote like or corresponding parts throughout the several views, and in which Q 1 v Figure 1 is afragmentary sectional view showingthe invention in use. i V Figure vZ isa detail view showing the man ner of connecting the mixing device with the Figure 3 is a longitudinal"sectional view of the mixing device.

In these vlews 1 indicates a mixlng' 'd'evlce which has one end inserted in theair in take 2 ofthc carbureter A-of the engine. The The device is connected by thepiping l with a device is held in place by the clips 3.

tank 5which is adapted to be filled with compressednatural gas and a pressure gage 6 is connected with the pipelineby the pipe 7, the gage being preferably arranged on.

the dash of the vehicle; -A pressure regulat ingvalve 8 is'arranged in 'thepipeline for.

'reducingthe pressure of the gas passed into the mixerr The flow 'ofgas into :the mixer lar stem' which [slides through a longitudinal bore constituting'the' inlet of. the mixing device at one endthereof, and whichstem 8 is provided 'with openings 9" at diametrically being openedfby the suction created by the. engine. This valve includes a hollow tubuopposite points and immediately adjacent the valve proper; whereby the fuel is al-.

the valve is moved far enough away from its seat to permit the openings to movebeyond the bore. Air ports ll are formed in the mixer and these :ports are adjustable by means of the sleeve 12 arranged on the mixer and having the ports 13 therein. e

When the; engine is to be run by gasthe needle valve of the carbureter is closed so as to shut offthe supplyof' gasoline or other fuel and the valve in thetank is opened to permit the gas to flow through the pipeline.

past the regulating valve'8 and into the mixing device. In this device the gas is mixed with air flowing throughthe ports 11 and lowed to pass through said openings when the mixture then passes into the cylinders where it is exploded in the usual manner. As will be seen the'valve 9 willprevent the flow of gas into the mixing device until the engine is in, operation when the suction created 'by the moving pistons w ll act to open the valve 9 against the action of its spring'and draw in a supply of gas and air to form an explosivemixture. The gage 6 g l will indicate the amount of gas in the tank and the parts areso arranged that the tank can be easily substituted by a full one when itbec'omes empty. 7 Whenever desired the vehicle can-be run on liquid "fuel by opening the needlevalve to permit the fuelftdpass into the carbureter. 1 e

bon Thelinvention iseasily. and quickly applied to an internal combustion: engine engine can be runon liquid fuel whenever.

considerable extent 'so that a large quantity of gas ca-nbe carried'in the tank I have; found that by the use of natural f gas the operation of an internal combustion motor 1s more efficientz than when using liq 10'0 .uid fuel and there isno formation of car- It is thought from the foregoing descriptionthat the advantages and novel 'features of my invention Will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall Within the scope of the appended claim.

lVha-t I claim is I A fuel and air mixing device comprising a hollow cylindrical body having an outlet opening at one end, "and a centrally located longitudinal bore at the other end. constituting the inlet, a nipple projecting from the lastmentioned end of'said body, a spring pressed sliding valve arranged Within said body, said valve including a hollow stem In testimony whereof I aflix my signature.
