TANK GAUGE AND FILLING DEVICE Filed Feb. 14, 1945 INVENTOR. Se v e r a' n Fi Czfr/Wr Patented Oct. 16, 1945 UNITED STATES PATENT oI-'FicE TANK GAUGE vsllLIING DEVICE 'Y if, Severin F. Czerner, Kings Mill, Tex.
Application February 14, 1945, semi No. 577,831 z claims. rc1. '1s-32u) 'I'his invention relates to improvements in tank gauge and lling devices and, more specically,
it relates to certain improvements on the fuel tank filling device shown and described in my United States Letters Patent No. 1,673,348.
'I'he present invention has for one of its objects to provide a convenient device, of the character referred to, and which is of such construction that it will be possible to fill a tank of a tractor, truck, boat, airplane or the like by means of the suction effect in the manifold of the running internal combustion engine which obtains its fuel from the tank to be i'llled, so that no pumping of fuel from a storage tank into the vehicle tank will be necessary and that it no longer will be necessary to lift a heavy fuel barrel for the purpose of making its contents flow into a vehicle tank by means of gravity.
Another object of the present invention is the provision of a combined fuel gauge and tank filling device which will allow to ll a fuel tank of 1 a vehicle with a minimum of effort within the shortest possible time, and without spilling any fuel when the lling is done outdoors in windy weather or in the dark.
Still another object of the present inventionv is the provision of a device of the character described which will automatically interrupt the ow of fuel from the stationary storage tank to the vehicle tank when the latter is full, thus preventing an overilowing of the vehicle tank and reducing the fire hazard to a minimum and making it unnecessary for the operator to constantly watch the lling process.
Yet still another obiect of the present invention is the provision of a combined fuel gauge and tank filling device which can easily be attached to the tank iiller neck in place of the usual cap, which will work satisfactorily and will serve as a reliable fuel level indicator even if its gauge portion should be bent slightly and if its moving parts become loosened by wear.v
A further object of the present invention is the provision of a device of the character described which consists of only a few simple parts and which is inexpensive to manufacture, but well adapted to withstand the rough usage to which such devices are ordinarily subjected. l
Further objects of the instant invention reside in any novel feature of construction or operation or novel combination of parts present'in the embodiment of the invention described and shown in the accompanysgY drawing whether within or without the scope of the appended claims and irrespective of other specific statements as to the scope of the invention contained herein.
In the drawing:
Figure 1 is a vertical sectional view of a preferred embodiment of my invention, on the line I-I, Figure 2:
Figure 2 is a vertical sectional view of the device as it appears when it has been turned ninety degrees around its longitudinal axis relative to Figure 1:
Figure 3 is a cross-sectional view on the line 3-3 of Figure 1; and
Figure 4 is a vertical vsectional view of a detail partially broken away.
Similar numerals refer to similar parts throughout the several views.
In the Figures V1 and 2 of the drawing, the numeral I denotes a portion of the top wall of a vehicle tank with the finer neck into which the filler cap 2 of my device ts tightly or can be screwed thereinto, as in the instance shown, in place of an ordinary cap. A cylindrical body 3 extends upwardly from cap 2 and has normally a plug 4, through which extends a bore 4', screwed into its top portion. A'transparent tube 6, which can be seen through slots 5 in the body 3 is contained within the cylindrical body 3 and is located between the packing washers I5 and I6. A float 1, which is guided by wires 8 that engage grooves I in the periphery of iloat 1 (Fig. 3) is adapted to iioat upon the fuel within the tank, and to rotate a twisted metal strip 3 by means of a piece Il of metal tubing which is partially flattened in the middle. 'I'he top portion I0 of the twisted metal strip has a relatively iine twist in the opposite direction.
There is provided a cork screw connection for portion I0 at I8 through the structural members 2 and I6, so that the reversely twisted, finer pitched portion l0 of strip 9 will be advanced longitudinally of indicator housing 3 only a fractional part of the longitudinal displacement of the float, with changes in liquid level. The purpose of this construction is to permit the use of a relatively short indicator housing 3, in relation to the overall movements of the float.
A shut oif valve I2 is attached to the twisted' strip 9 in such a manner that, when the tank is full, it will close the opening in cap 2, through which the twisted strip extends. In Figure 1 the parts 1, 9, and I2 are shown in a position when.
the tank is approximately half lled, whereas ,in Figure 2 said parts are shown when the tank is full. A bent pipe' I3 adjacent to the body 3 also extends through cap 2, and its upper end portion is adapted for attaching a fuel hose thereto which leads to a storage tank or barrel (not shown); whereas its lower end portion 2|, which projects into the vehicle tank, is shaped in such a manner that it deilects the incoming stream from the float l (Fig. 2) 'I'he small perforation 2l `(Fig. 2) permits faster idling of the engine while filling fuel into the tank by the suction method referred to hereinafter.
If the vehicle tank is to he nlled by means of a pump, a fuel hose (not shown) can be inserted into or attached to the pipe i3, which (after the filling) can be closed by means of a cap (not shown) that may be screwed upon the upper portion of pipe It. But if the vehicle tank is to be nlled without the usual pumping facilities, for instance, if fuel in abarrel that stands on the ground is to be transferred inw the vehicle tank, the plug l is removed and a suction tube connection I1 (Fig. 4) `is screwed into the Part i: then'one end of a suction tube (not shown) is attached to the tube connection i1, and its other end is attached to ashut-oi! cock (not shown) on the intake manifold of the internal combustion engine of the vehicle. One end of the fuel hose (not shown) is tightly connected to the upper end of pipe I l and its other end is inserted into a fuel barrel or into a stationary storage tank. To prevent the end of the hose from sticking to the bottom of the barrel, it is advisable'to provide holes in the hose near the end. To prevent water andrust from entering the hose, the hole in the end should be plugged. With the engine idling at a good speed, the shutoff cock on the intake manifold of the engine is opened, and the fuel supply to the carburetor is shut on. While the 'engine is thus idling, it will empty the carburetory iand the suction in the intake manifold will drain the air from the vehicle tank through the bore I8 (Fig,A 4), thus causing a now of fuel from the barrel or storage tank into the vehicle tank through pipe i3, the cap 2 being tightened iirmly` upon the illler neck of the vehicle tank by means of an ordinary packing ring Il. While the fuel is passing through tube I3, a small spray of fuel will pass through the perforation zllthus maintaining a combustible mixture in the intake manifold after the fuel in the carburetor is used up. At this time, the operator will manipulate the carburetor throttle to a slow idling position, and the engine will run slowly and smoothly. When the vehicle tank is filled up,the automatic shutolf valve l2 will close (Fig. 2), thus stopping the engine as it will no longer be supplied with fuel vapor from the vehicle tank. A stopping of the engine will automatically interrupt the now of fuel into the vehicle tank. Y

2. In a tank gauge and nlling device having a nller cap which fits the filler neck of a tank and carrying at its outer side a transparent tube which is connected to the interior ofthe tank by a bore through which extends a fluid level indicator that is actuated by a float, the combination of a pipe connection at the top of said transparent tube adapted for attaching thereto a suction tubingv that leads to a cock on the intake manifold of an internal combustion engine. with a bent pipe adapted for attaching a fuel hose thereto and extending through the filler cap adjacent said transparent tube and having a lower end portion which projects into the tank and which is shaped in such a manner that it denects the incoming fuel stream from said float; and a shut-oil' valve attached to said indicator and adapted to close the opening in theilller cal `when the tank is full, all substantially as described.
