Patented Aug. 22, 194-4 FILLING APPARATUS FOR TRACTOR GASOLINE TANKS Fred T. Ranney, Minneapolis, Minn. Application May 5, 1941, Serial No. 391,820 H Claims.
This invention relates to improvements in filling apparatus for gasoline tanks and particularly to a filling apparatus suitable for transferring gasoline or similar liquid fuel products from a container to an engine fuel tank positioned thereabove.
Much labor and danger attends the present method of filling the fuel tanks of tractors, combines, motor launches, etc. from storage tanks, because of the position the operator must take while pouring the gasoline from a bucket into the fuel tank, which is usually positioned too high to be filled from the ground. Furthermore there is danger of fire due to the gas fumes radiating from the exposed gasoline, and the fact that some of the gasoline may be spilled in the transfer.
It is the principal object of the present invention to produce a filling apparatus for fuel tanks which will constantly maintain the fuel passing from the fuel container to the fuel tank, completely confined to prevent spilling or evaporation to the atmosphere, and a means whereby the liquid fuel is raised by the differential of pressure in the storage tank and the engine fuel tank through the means of the suction of the engine. 1
Another object of this invention is the provision of a fuel tank filling means having automatic valve means whereby the flow of liquid to the tank is stopped when the liquid level in the .tank has reached a pre-determined heighth,
thereby preventing back flow of the liquid fuel to the container.
- .A further object of the invention is the provision of a filling apparatus for fuel tanks having means whereby a limited amount of gas from the fuel tank will be fed to the engine during the .tank filling operation even though the regular fuel supply through the carburetor is stopped.
Other objects are simplicity and economy of construction, efficiency and ease of operation, and adaptability for use with the various types of motor vehicles using a liquid fuel.
With these objects in view, reference will now behad to the drawing wherein:
Figure 1 is an elevational view partly broken away of a filling apparatus for engine fuel tanks embodying this invention.
Fig. 2 is an enlarged central sectional View of the pump portion of the filling means with parts shown in dotted lines.
Fig. 3 is an enlarged fragmentary sectional View of the valve structure.
Throughout the several views like reference characters refer to similar parts and the numeral the motor 8 of the t'ypical'farm tractor or of any other type of automotive vehicle having an internal combustion engine as the motive power.
Tank 5 is provided with a neck I 0 through which is-formed' an opening to the tank. 'This neck I0 is internally threaded at I2.
The main body I4 of the apparatus has a central bore I6 which extends lengthwise therethrough. The lower portion I8 of body I4 is offset and threaded at 20, and screwed into the threaded neck IU of the tank, whereby communication between the tank and body member is provided.
A pair of gaskets 22 and 24 are spaced apart by the metal washer 26 and fitted over the lower portion I8 of the body member and serve to seal the joint between the neck It and the body member. The upper portion of the body member I4 is provided wtih a cover 28 hinged at 30 to the body member and having a tongue 32, notched at 34, to receive a spring wire bale 36 to secure the cover in the closed position. The upper end of central bore I6 is tapered at 38 to present a frusto-conical recess to receive the free end of the flexible tube 40 to form an air-tight joint therewith. The other end of tube 40 is inserted into a fuel container 42 through a top opening 44 and extends to a pointadjacent the bottom of the container. When a vacuum is created in the fuel tank 6, as hereinafter described, the atmospheric pressure on the liquid surface in the container 42, due to the inlet opening 46, will force the liquid fuel through tube 40 and into tank 6 through body member l4.
An automatic valve control means 48 is provided in the body member I4 to permit the suction of air from the fuel tank and to cause a breaking of the vacuum line when the liquid fuel reaches a predetermined level in the fuel tank filling apparatus for gasoline tanks.
Projecting into bore I6 is a rib 50 which extends downwardly from the threaded end of body member I4 into tank 6. This rib is cylindrically recessed at 52 to receive the cylindrical valve member 54 which normally rests on the sleeve 56 which is threaded into the lower end of rib 50 for longitudinal adjustment therein. The upper end of sleeve 56 is offset to permit air to pass between the valve and the sleeve. The diameter of valve 54 is slightly less than the diameter of recess 52 to admit air therebetween and its upper end is conical in shape at 58 to form a valve suitable for co-acting with the valve seat 60 formed in the body member I4. The upper end portion the cylindrical valve 54.
opening 84 formed through the wall of body member opening between the valve 54 and the wall of recess 52 will be lessened. This variation in the area of the inlet opening makes it possible to regulate the closing of valve 54. The reduced upper portion 52 of recess 52 communicates with the laterally disposed recess 54. This recess 64 is threaded to receive the nipple 66 to which is 7 attached suction pipe 68 by means of the coupling 10. This suction pipe 68 is provided with a control valve 14 and communicates with the intake 16 to engine 8. In the operation of engine 8 a suction, due to the action of the pistons in the cylinders, sucks the fuel from the carburetor 18 through the intake 16 and also creates a suction through pipe 68 thereby producing a lowering of the pressure in fuel tank 6.
Since in some instances the fuel supply in the carburetor may be exhausted, provision is made for drawing the fuel from the gas being delivered from drum 42 to the fuel tank 6 through the suction pipe 68. This means contemplates the provision of a sleeve 80 having an aperture 82 of relatively small diameter inter-connecting bore IS with suction pipe 68 through recess 64.
Since aperture 82 is relatively small and a suction is always created therethrough during the tank filling operation, it is provided that the volume of suction pipe 68 is sufliciently large to exert a relatively high vacuum in recess 52 above In the filling operation, when the engine 8 is running and the air is forced from tank 6 by the suction created through pipe 68, the liquid fuel in container 42 will be lifted through tube 40 which is positioned in the upper tapered end portion of bore l6 and be delivered into tank 6. When the liquid level in tank 6 raises toseal the lower end of recess 52 in rib 50 then the valve 54 will be raised to valve seat 59 thereby preventing the flow of air upwardly through recess 52, however, a slight flow of gaseous mixture will pass through aperture 82 to the engine. An the Wall of body l4 connects the interior of said body member with :the atmosphere. This openingis slightly larger than the aperture 82 thereby insuring a reduction of the pressure in tank 6 which will permit the liquid in tube 40 to flow back to the container 42 so that as the operator removes the outer end of tube 40 from body member hi there will be nogasoline in the tube to spill onto the engine parts. i
In practice, it has been found convenient to make the aperture 82 about b of an inch in diameter and the opening 84 about 0 of an inch. To prevent too high a pressure against-the walls of tank 6, a safety valve 88 is positioned in M to communicate with the vacuum chamber of the fuel tank. This valve is of a standard type and is adapted to be adjusted at any desired pro-determined partial vacuum.
Since this valve is adjusted to a relatively high vacuum, it will not interfere in any manner with the normal operation of the device during the filling of the tank. The best procedure inthe use of this filling apparatus is as follows:
The apparatus is mounted on the tractor parts as indicated and described and then in-tested to be sure that all connections are air-tight, let the engine idle slowly with the valve 54 open to create a good suction in intake 16, open valve 14 so that the air is drawn from fuel tank 6 thereby reducing the pressure therein whereby gasoline will be forced from the drum 42 from tube 40 to the tank 6.
As soon as the tank is filled to a pre-determined level valve 54 will close and air will rush in through opening 84 to reduce the pressure in tank 6, thus making it possible to safely remove tube 40 and close the cover member 28 which will prevent escape of gas fumes therefrom.
The opening 84 will admit sufficient air at all times to permit proper gravity flow of the liquid fuel to the carburetor. In most of the filling operations the difference of liquid level in the fuel supply drum and the fuel supply tank seldom exceed 6 feet which would necessitate the production of only a relatively low vacuum, however should the distance be greater, thus necessitating a higher vacuum for operation, sleeve 56 could be adjusted to regulate the closing time of valve 54.
Minor changes might be made in the structure and relative relation of the various parts without departing from the spirit of this invention.
Having thus described the invention, what is new and desired to be secured by Letters Patent fuel tank, a suction tube connecting said chamber through said hollow body member and fuel tank with said fuel container, a valve operable when the liquid in said tank reaches a predetermined level to partially close the source of suction to said elevated tank, a restricted aperture whereby fluid fuel from said engine tank passes to said chamber of low pressure when said valve is closed and an atmospheric bleed hole rela- ,tively larger than said aperture communicating with said fluid fuel tank whereby the vacuum in said elevated tank is reduced gradually until the flow of fluid fuel from said container to said engine tank is stopped.
