MOTOR-FUEL SUPPLY AND BLENDING AND ENGINE-STARTING MEANS.

Application filed January 16, 1918.

One of the objects of the invention is the provision of a highly eflicient fuel-blending and supply valve, through the medium of which an engine may be supplied at the starting thereof with high-grade gasolene, and after the engine warms up sufficiently a lower grade of hydrocarbon may be used to actuate the engine; also, portions of each hydrocarbon fuel may be used in desired proportions, or either one of the hydrocarbons or hydrocarbon fuels may be used inde pendently of the other and in desired succession, and may be blended by cutting in of the one synchronously with'the cutting out of the other.

Another object of the invention is the provision of an apparatus, including the valve alluded to, designed for use on a motor vehicle, and constructed and arranged with a view to enabling the driver of the motor vehicle to conveniently control the supply of different hydrocarbon fuels to the carbureter of the engine, either separately in desired succession or together in varying proportions, and to cut in one fuel while relatively cutting out the other, as different circumstances require.

Other objects and practical advantages of the invention will be fully understood from the following description and claim; it being distinctlyv understood that the embodiment herein disclosed is but oneexpressionv offmy.

invention, and that various changes or modifications may be made within the scope of my invention as defined in said claim.

In the accompanying drawings, which are hereby made a part hereof:

Figure 1 is a view of so much of a motor vehicle as is necessary to illustrate the present arrangement of my. novel valve and its appurtenances, relative to the carburetor,

the steering post and other general elements of the machine, as well as the fuel tanks hereinafter specifically referred to.

Specification of Letters Patent.

Patented Jan. 4, 1921.

Serial No. 212,141.

Fig. 2 is an enlarged detail plan view of the dial employed on the steering post.

Fig. 3 is a detail view taken at right angles to Fig. 2. on the line 33 and showing the fuel-supply regulating lever.

Fig.4 is an enlarged side elevation of my novel valve per se.

Fig. 5 is a vertical, diametrical section of the same.

Similar numerals of reference designate corresponding parts in all of the views ofthe drawings.

In the present and preferred embodiment of my invention, my novel valve. 1 is disposed on the forward side of the dash-board 0f the machine, and in the relation illustrated to the manifold 3 of engine 4, the steering post 5, the steering wheel 6 thereon,

the carbureter '7, and a tank 8 carried on the forward side of the dash-board, and designed to contain high-grade hydrocarbon fuel for starting purposes.

A pipe 9 leads from the lower end ofthe valve 1 to the carbureter 7 to conduct fuel or fuels to the latter, and a pipe 10 leads downwardly from the tank 8 and issuitably connected, preferably by a solderless joint, to, the upper nipple 11 of the valve 1. The regular fuel-supply pipe 12 is similarly. connected to the lower. nipple of the valve; it being understood in this connection that in the-present arrangement the lower nipple 13 is the one that cuts, in last.

14: is a suitably-marked dial, connected through braces 15 with the steering post 5,. 16, is. a fuel-supply regulating rod which is preferably, though not necessarily, arranged within the steering post. 17 is a fuel-supply regulating lever fixed on the upper end of the rod16 and having. an opening 18 overv the dial-markings to render easy the reading thereof, and also having. a suitable lever; Clamp 9 Il a. 3 des ned o engage t dial and prevent casual movement. of the. le-. ver 17 relative thereto.

Aslclearly shoW-n'in. Fig. 1 the rod 16 ex: tends forwardly of the dashboard 2 for-fa purpose hereinafter set forth.

My novel fuel-blending and supply valve 1, which constitutes the chief feature of my invention, is clearly shown in Fig. 4, and will be fully understood by reference to said figure. At the upper end of the valve is an eye 20 that is interlocked with a complementary eye on the lower end of a shaft tion, 20.", ge d. e famed, nd. of the rod 16 to effect connection between the two. The said eye 20 is carried on a shell 30, open at its lower end and provided in its side wall with diametrically-opposite slots 40. The said slots 40 are for the reception of the beveled ends of a diametrical pin 50, suitably fixed in the upper reduced portion 60 of the movable body of the valve, which portion 60 is disposed and movable in the shell in an endwise direction, for a purpose hereinafter set forth. The said reduced portion .60 of the valve body is guided in the upper flanged end of the upper casing section 90 which serves as a housing for a spring 80; the said spring being interposed between the flange of the casing section 90 and the comparatively large portion 150 of the valve body, as illustrated. The upper casing section 90 is exteriorly threaded for the engagement of a lock nut 100 by means of Which the upper casing section may be securely locked to the union 110; and it will also be noted that the upper casing section 90 is provided with a comparatively thick portion 9 of hexagonal form in cross-section, which serves as a bearing for a screw 200 on which is a jam nut 21 to prevent casual movement thereof. The lock nut 100 is also by preference of hexagonal form in cross-section, and the union 110 is of similar formation. At 140 the union 110 is provided with an interior flange 140, and between the said flange 140 and the upper end of the lower eXteriorly-threaded casing section 130 a packing washer 13 is interposed; the said washer being designed to act as a piston packing in combination with the portion 150 of the valve body. The lower casing section 180 is tapered as shown to its eduction orifice 24 which is connected, preferably through a solderless joint to the pipe 9, Fig. 1, that leads to the carbureter 7. The valve body in additionto the portion 60- 150, which is solid, comprises a lower hollow portion 22 which is fixedly connected to the solid portion 60-150, preferably by a cross pin 180. This hollow portion fits snugly inthe lower casing section 130, and is provided with oblong induction openings 26, 26 in its side wall and eduction openings 23 in its lower end wall which latter is tapered in conformity to the lower end of the casing section 130 as illustrated.

In the portion 150 of the valve body is one form of groove 190 which receives the inner end of the screw 200 and by means of which the valve body is raised while being turned to operate.

The lower casing section 130 carries the before mentioned nipples 11 and 13, and in the upper side of each of these nipples is a set screw 300 constructed and arranged to turn stiilly. These set screws have for their function to enable the person in authority to regulate the amount of hydrocarbons that pass to the valve 1, should it prove desirable to do so.

At this point I would have it understood that the portion 60 of the valve body and the slotted shell 30 are so relatively arranged that when the valve body is raised to its greatest height it will not quite touch the top of the inner side of the shell 30. Then when the valve body recedes as the valve is closed the valve-body portion 60 passes downwardly inside of the sleeve, and the cut-off lower end of the valve body is securely seated against the tapered lower end of the casing section 130 so as to effectually interrupt communication between the interior of the valve-body portion 22 and the eduction orifice 2 1.

It is also to be understood that when the lever 17 is in the position marked 9 in Fig. 2, the valve body rests in a corresponding position in its casing, and so with the other positions of the lever and valve body.

It will be gathered from the foregoing that in the operation of my improvement, turning of the lever 17 and rod 16 will be attended by turning of the valve body in the casing, when by reason of the groove 190 cooperating with the screw 200, the valve body will be raised against the action of the spring 80. This will unseat the valve body to effect communication between the interior thereof and the eduction orifice 24 of the valve casing, and at the same time will admit hydrocarbon fuel into the portion 22 of the valve body from whence such fuel will pass through the apertures 23 to the eduction ori- V fice 24.

When the lever 17 and rod 16 are turned in the opposite direction, the valve body will be correspondingly turned to seat the valve body and at the same time close communication between the induction ports of the valve body and the fuel-supply ports in the casing.

It is to be understood in the above connection that I do not desire to confine myself to the illustrated relative arrangement of the ports in the valve casing and valve body, in asmuch as said ports may be arranged in any manner that will meet the requirements of my invention without involving depar ture from the scope of the same as claimed.

By virtue of my novel valve it will be manifest that a high grade fuel from tank 8, for instance, may be used to start the engine, thus eliminating starting trouble to a considerable extent. Also, that blended fuel may be used with efficiency, thereby reducing the cost of operating the engine. The said blends may be made in any desired proportions, and may include very low grade gasolene and even kerosene. Then when the engine becomes sufliciently hot it may be eliiciently operated on low grade fuel alone.

I have entered into a detailed description of the construction and relative arrangement of the parts embraced in the present and preferred embodiment of my invention in order to impart a full, clear and exact understanding of the said embodiment. I do not desire, however, to be understood as confining myself to the said specific construction and relative arrangement of parts since in the future practice of the invention such changes or modifications may be made as fairly fall within the scope of my appended claim.

Having described my invention, what I claim and desire to secure by Letters Patent,

A. fuel blending and supply valve, comprising a casing having fuel inlet ports in its side and an eduction orifice at one end, a rotary valve body disposed in said casing and having a hollow portion in which are induction ports and one or more eduction ports and also having a portion extending through the opposite end of the casing, lateral projections on said portion beyond the casing, a shell open at its lower end and provided with diametrically opposite slots and receiving the projections in said slots; said shell being adapted for connection to operating means, cooperating means of the casing and valve body for moving the latter endwise when it is turned about its axis, and a spring interposed between the casing and the valve body for assisting in the seating of the latter.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

WILLIAM E. CHENOT.
