T0 all whom itfmayrlconcem: ABe it known ythatl, EUGENE J. FARKAS, a citizen of the :present domainl of Hungary, lhaving' applied for and received my first papers for n'aturalizationl in the United States, residing at Detroit, in the county of Wayne and'State ed new and useful Improvements in a Combined` Fuel ,Valve and Sediment Bulb, of which the following is a specification.

The object of my invention is to provide new and useful mprovements in a combined fuel valve and sediment bulb of simple, durable, and inexpensive construction.

A further object `of `my invention is to rovide a device adapted to form a common sediment bulbV for two tanks of different kinds of fuel thereby eliminating, as far as possible, duplicate sediment bulbs and fuel lines with the consequent tendency of ad-r ditional parts to get out of order.

A further object of my invention is to rovide a valve adapted to control the supply of fuel to the carburetor so that the engine, operated from the carburetor, may be operated upon `either of two different kinds of fuel or the fuel may be cut olf entirely.

A further object of my invention is to provide an improved two-way valve especially adapted to co-operate with fuel inlet ports and a sediment chamber, the arrangement being such as to allow fuel from either of the two 'ports to reach the sediment chamber.

A further object of my vinvention is to provide a sediment bulb or casing, having fuel inlets and outlets therefrom which are so arranged that fuel passing through the bulb to the carburetor must pass through a screen or strainer, and which is so arranged that either of two kinds of fuel, when fed into the bulb, just pass through this strainer.

A further object of my invention is to provide a drain valve or plug, which is so arranged that it may drain the fuel and sediment from the portion of the interior of the casing which is enclosed by the screen.

A further object of my invention is to l provide an improved mounting forthe screen whereby it may be readily removed for cleaning and inspection when desired.

A further object of my invention isto provide a casing which may communicate directly with one of said tanks.

With these of Michigan, have invent-- and other objects in view, my` Y L A ppnc'ation md october s, 1926. senat-m1. 415,529.

invention consists in the arrangement, combination, and construction of the `various parts of and shown in the accompanying drawings, in which v v Figure 1 is a transverse View through a fuel tank construction and showing an elevation of my improved 'combined sediment bulb andfuel valve.

Figure 2 is a side elevation of my improved valve, and

Figure 3 view through the' casing of my improved sediment bulb and fuel valve.

Referring to the accompanying drawings, I have used the reference numberal..10 to indicate, generally, a1 fuel tank which is substantially oval in cross section and provided with a plurality of baffle plates 11, designed to prevent the fuel in the tank from undue washing backand forth within the tank due to the movement of the latter. Mounted within the tank 10` and enclosed thereby is a second fuel tank 12, having a filler opening 13 and an outlet opening 14. The tank 10 has an outlet opening 15.

It will be understood that the fuel tanks 10 and 12, are designed to be used where an internal combustion engine may be driven by either of two fuels, such, for instance, as gasoline and kerosene. gasoline would be placed within the tank 12v and the kerosenewithin the larger tank 10.

For conducting the fuel from the tank 12 I provide the following mechanism:

The outlet opening 14; of the tank 12 is countersunk somewhat at, 16 and a registering opening 17 is provided in the bottom of the tank 10. A gland 18 has a iange at one 'end thereof received in the countersunk portion 16 and the body thereof extended through the openings 14 and 17. A nut 19 is screwed on to the body portion of the gland 18, outside of the tanks, in such a position that the webs of the tanks' 10 and 12, around the openings 14 and 17 therein, will be gripped between the nutv 19 and the flange of the gland 18 when the nut is tightened, thereby insuring a fluid-tight connection.between the tanks 10 and 12 and the gland 18. Threaded into the gland 18 is a pipe 20 which runs into anr elbow ,21, which in turn connects with a fuel pipe 22, 'the y Form MoTon coIIrAnY, 0E comonATIoN or DELAWARE., g. f

my'improveddevice," lLas described 1n vthe specification, claimed 1n my claims, Y z v is a vertical central sectional In such a case the latter being connected into a friction orexpanding joint 23. From the connections just described it will be seen that fuel may be removed from the tank 12 without it coming in contact with the fuel in the tank l0, or without there being danger` of the fuel being lost through leakage.

Around the opening l5 in the tank l() a flange l5 is riveted, this flange being provided with a threaded opening 24.

My improved combined sediment bulb and valve comprises a casing A, having in the bottom thereof a relatively large recess 25 adapted to form a sediment pocket, and in the upper central portion thereof, a substantially cylindrical recess 26 adapted to form a valve casing. Extending upwardly from the portion of the casing around the recess 26 is a nipple 27 which is externally screw-threaded and has a central opening or port 29 therein designed to communicate with the recess 26. This nipple 27 is screwed into the flange 23 on the tank l() to form a {luid-tight joint with the tank so that fuel from the tank may pass down into the rccess 26. A similar nipple 2S projects laterally from theupper portion of the casing A and also has a central opening or port 30, which communicates with the recess 26. This nipple 28 is decigned'to communicate with the friction joint 23 at the end of the pipe 22, and to form a liquid-tight joint therewith.

From the description of the foregoingparts it will be seen that fuel may be supplied to the recess 26 through the opening 29 in the nipple 27, from the tank 10, or through the opening 30 in the nipple 28 from the tank l2.

Mounted wit-hin the recess 26 is a substantially cylindrical valve member 3l havin T shaped opening 32 therein.

eferring to the Figure 3, it will be seen that when the valve 3l is in a position there shown, then that fuel cannot enter the recess 26 from either the openings 29 or 30. If, however, the valve be rotated one-eighth of a turn in a clockwise direction, then that the fuel may enter the recess 26 and pass through the valve from the port 30, this fuel owing through the opening 32 through one end of the long portion thereof and through the short arm thereof. The recess 26 is connected with the sediment pocket 25 by a passageway 33, and when the valve is moved to the position stated it will be seen that the short arm of the passageway 32 will register with this opening 33 so that the fuel received from the port 30 will pass into the sediment bulb pocket 25. If, however, the valve be rotated in a counterclockwise direction back to the position shown in Figure 3 and then another oneeighth turn, it will be seen that the long portion of the opening 3 2 willconnect the port 29 with the passageway 33, so that the fuel from the opening 29 will be fed into the sediment pocket 25. The rotation of the valve from the position shown in Figure 3, in either direction will, therefore, permit fuel to be fed from either of the tanks 10 or 12, selectively.

The bottom of the sediment pocket 25 has a relatively large threaded opening 34 therein, designed to receive the plug 35. The latter has a central opening therein which is comparatively wide at its upper portion 36, contracted to form a valve seat 37 intermediate of its ends, and threaded at 38 to permit a valve 39 to be screwed into that portion of the plug. The valve 39 is so arranged that when it is screwed up tight it will completely close the valve opening 37, and when it is uns-crewed then that the liquid within the sediment pocket may escape through the valve opening 37.

Extending from the top to the bottom of the sediment pocket 25 is a cylindrical screen member 40, which is fastened to the plug 35 within the recess 36. At the top of the screen or strainer 40, the flange 41 is secured. this being designed to enter and fit closely into a pocket 41 at the top of the recess 25 and around the passageway 33.

A. nipple 42 extends laterally from the casing adjacent to the upper part of the sediment pocket 25 and is provided with a screw threaded end portion 43, and a central opening 44, designed to form an outlet port for the sediment pocket.

From the construction of the parts just described it will be seen that fluid admitted into the sediment pocket 25 through the passageway 33, will flow down into the interior of the cylindrical strainer 40. It may then pass through the strainer and out of the sediment pocket, adjacent to the top thereof, through the outlet port 44. When desired, however, the valve 39 may be unscrewed to drain the sediment pocket therebv draining out such impurities as may have been strained out of the fuel by the strainer 40. If it is desired to clean the sediment pocket thoroughly, for any reason, or to clean the strainer cylinder, then the plug 35 may be unscrewed thereby removing the strainer 40, so that it may be washed in any desired manner. In this connection it may be mentioned that the strainer 40 may, if desired, be stitfened with any suitable means so that when the plug 35 is screwed into the sediment pocket then the flange 41, at the upper end of the strainer, may be forced into the recess 41A to thereby form a substantially liquid-tight joint between the flange and the recess. This engagement must, however, be so arranged that it will not interfere with the forming of the liquid-tight joint between the plug 35 and the casing A,

The nipple 42 is connected by suitable feed lines with the carburetor in an internal combustion engine and it will be seen that when the parts are so arranged, then that the valve 31 may be operated to feed through the nipple 42 either of the fuels in the tanks 10 or l2, or to cut off the fuel from the nipple 42 altogether.

For operating the valve 31 I provide the following mechanism: It will be understood that the valve 31 is rotatably mounted within the recess 26 and I preferably make the body of the valvel somewhat tapered, as is indicated by the dotted lines 45 and 46 in Figures 1 and 3, and taper the recess to correspond. A stem 47 projects from the body of the valve 31 and has an operating arm or lever 48 screwed to the outer end thereof. Encircling the stem 47 between the casing A and the lever 48 is a spring 49, which tends to yieldingly draw the valve 31 through the recess 26, thereby drawing the tapered portions of the valve 31 and recess 26 into closer engagement. The lever 48 is provided with laterally extending ears 50 at either side thereof, which are designed to contact with the stop 51 which extends outwardly from the casing A into the path of these lugs 50, so that contact of either of these ears with the corresponding side of the stop 51 will limit the movementof the lever 48 to properly position the valve 31 so that liquid may pass therethrough from either port 29 or port 30. In the form of valve here shown the vertical position of the arm 48 is the closed position of the valve so that no stop is necessary for the closed position. At the bottom of the lever 48 is an opening 52 designed to receive an operating rod 53, which may be extended to any suitable place to thereby permit the operation of the valve 31 from the most convenient position for the operator.

Among the many advantages arising from 'the use of my improved device it may be mentioned that I am enabled to dispense with an extra sediment bulb and also with a special casing and bracket or other mounting for a fuel valve. By eliminating a large amount of the fuel line material which has been used in the past I am enabled to minimize the danger of leakage and other troubles from a fuel supply system. By placing the tank 12 within the tank 10 and by the relation of the parts, as shown, I am enabled to economize on space, material and ease of manufacture, and at the same time insure liquid tight joints.

Some changes may be made in the arrangement and construction of the various parts of my improved device without departing from the spirit of the invention therein and it is my` intention to cover by my claims such changes as may be reasonably included within the scope thereof.

I claim as my invention:
