To all whom it may concern:

Be it known that we, ALFRED Fnnsonn and JOHN L. FRESHEL, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements 1n Motor-Fuel-Supplying Apparatus, of which the following is a specification, reference being, had therein to the accompanying drawing. 7

Our invention relates to apparatus for supplying fuel to explosive or internalcombustion engines, and contemplates sultable holders or containers separately charged with the "ingredients of the explosive fuel or mixture in predetermined quantities under pressure and adapted to be repared at .a central station with their 0 arges and adapted to be shipped or delivered asapackage to the user and by him placed 1n communication with the engine or charged while associated with theengine, and means to control the delivery of the ingredients in the form of explosiverfuel or mixtureto the engine.

In the drawings Figure 1 is a viewof an embodying our present mvent1on;.-Fig. 2 is a sectional view of a form of container or holder that ma be used; Fig. 3 is a sectional view of suita le valve mechapparatus anism for the container, and Fig. 4 is a sectional view of a suitable controlling valve in the pipe connections.

In carrying outour invention we employ suitable containers of fluid-tightconstruction adapted to be prepared respectively at a central station with charges of explosive gas and oxygen under pressure therein and adapted to be delivered or shipped to the user and by him laced in communication with means to fee their contents as a mixture to the engine or charged while in connection with the associated en 'ne, and

. means'to control the mixing of t e oxygen .v ties or volume.

and explosive gas in predetermined quanti- In the practice of our inventionwe may employ any suitable gas which when mixed fwith oxygen will produce an explosive mixture suitable for fuel in various types of internal #u'ctibn-producerby drawing air through a combustion or explosive engines ,e .'.;2; aay use producer-gas generated in a body of burning charcoal, coke or other carbon, or we may use the vapor or gas of hydrocarbons such as gasolene or petrol, orfof kerosene or alcohol, or we may use acetylene gas. The oxygen and gas are introduced in measured charges or volumes into fluidtight holders or containers 5, of any suitable form. and dimensions for transportation and shipment, each having an inlet and outa let pipe 6 to allow its contents to be intro duced and discharged and controlled by any suitable valve mechanism which may be closed to shut off its escape and render the vessel hermetically sealed. The con-- tainers are separate in that each is a se arate chamber or compartment, though t ey may be arranged in sets of two or more chambersin the same casing or body as, for example, by using a singletank having a dividing wall 7 as'shown inFig. 2. In eithercase the proportion of gas andoxygen are predetermined and regulated according to requirements to vary the owereffect of the explosion of their uiiimate mixture in the engine whilethe quality of the mixture produced by the contents of the associated containers is constant and uniform, and the quantity may bevaried to providepredetermmed amounts of runningfuel for runs of different durations or distances. The containers may be charged with their contents at the central or supply station'and then so delivered or shipped to the user as a package or unit adapted to be placed by their pipesvo in a communication with the engine'towhich it is intended to en ply the fuel, and where such en ine is a ve.1cle engine the containers may e made in the form of a tank attachable to and detachable from the vehicle so as to replace the gasolene tank now commonly mounted on thevehicle; as shown in the drawing in the present instance the tank is made in the cylindrical form of a type of gasolene tank new fire uently used on automobiles, and may be etachably secured in place by any suitable means sum as the half-round brackets 9 provided with straps 1O hinged thereto at 11 and held in place by any suitable lock 12. It is of course understood that the tank may be of any suitable form or contour and mag be attached in any convenient position to t e associatedvehicle,which may be an automobile, any other carrier.

The contents of the chambers are com pressed or under pressure and are introdu'ced through the opening 6, and in order to deliver the material to the engine under uniform pressure we provide each chamber with a reducing-valve of any suitable con struction; a closing valv also may be used .to seal the chamber after it is charged and before it is used. For these purposes the pipe 6 i provided with an enlarged extension 13 divided into upper and lower chambers l4: and 15 by a wall 16 having a passage 17 the chamber 15 has a screw-threaded needle valve 18 arranged in the line of the pipe 6 and having its outer end squaredto receive any suitable adjusting tool to close the pipe to seal the same when desired and to open it to permit the flow of the contents of the tank when desired; the upper chamber 14; has an equalizing valve comprising a diaphragm 19 above its opening into the outlet pipe 20 and a depending valve stem having a valve 21 normally below the passage 17 and adapted to seat more or less therein under varying pressure applied to its diaphragm. The chamber 15 also has an inlet 22 closed by a removable screw cap 23 which also fits the end of pipe 20. When the chamber is to be charged at a central station the cap 23 is removed from inlet 22 1 and screwed upon the end of the pipe 20,. and the charging-pipe leading from the charging-apparatus is-connected to the inlet 22 in its place and the valve 18 i opened whereby the fuel ingredient is passed to its proper chamber... When each chamber is charged its associated valve 18 is closed to hermetically seal it and the cap 23 is restored to its place on the inlet pipe 22,

whereby a definite quantity of fuel-ingredients is ready for use. When a pair of containers or the twochambers of a single container are charged with their respective fuel ingredients and are delivered or shipped to; the user, their .outlets 20 are connected by suitable couplings or unions as to the supply 1 pipes 25 .and.26 of an explosiveengine 2?,

usually to the manifold thereof.

Any suitable mechanism is utilized to con- 5 trol and regulate the feed of the fuel ingredients to the engine under the control of the operator. For example, the pipes 25 and 26 may lead to asuitable valve-casing 28 forming a mixing chamber, having two in- ,lets 29 and 30 connected respectively to the pipes anda single outlet 31 leading to the engine, and containing a valve 32 having ports 33 and 34: adapted to register with inlets 29 and 30 when-the valve is in one position and closing the inlets when in another position, the valve being controlled by the operator, as the chauffeur at the wheel 35, by

motor boat, aeroplane or 1 means of handle 36 having suitable connections 37 to the stem of the valve. When the parts are assembled with the reducingvalves properly set for the desired pressure will pass from their chambers to the mixing- ,and the valve 32 open, the fuel ingredients chamber 31 and thence to the engine,"and the communication of the engine with the fuel mately mix the fuel ingredients and also insure a larger suppl of mixed fuel at the initial operation of t evengine.

While the chambers may be char ed, at a central station and delivered to t e user, it is also to be understood that our invention contemplates a vehicle'such as above stated provided with chambers forming permanent parts of its equipment and which may be so charged while mounted thereon by merely closing the valve 32 and placing the respective inlets 22 in temporary communicationwith suitable charging apparatus at such central station or other place of supply.

The apparatus will not only supply the fuel required to run the engine any given distance or period of time regulated by the predetermined amount of the fuel-content, but by reason of the mixture being under pressure-it will in connection with other appliances also make the engine self-starting when the control-valve is opened and the sparking-plugs are provided with electric current from any suitable source of electrical supply. The fuel mixture is composed of an explosive gas and oxygen which i fed direct to the engine by closed pipe-connections, and. the user dispenses with the use of gasolene and the hitherto necessary local vaporizer or sprayer required to vaporize his gasolene or other liquid fuel and the hitherto necessary local carbureter for mixing or mingling the vaporized liquid and air, and obviates the attendant and wellknown objections and defects of these and their associated parts hitherto required to produce a proper fuel mixture and supply.

By this invention the explosive power of the fuel is increased as the ingredients are in a dry state, and increased power is obtained or a smaller'motor may be used for any given load or work.
