Be it known thatil,-rrsnrsr Q-Bmnnmr, a citizen of the United fitates, residing at Minneapolis, in the county of:- Hennepin and State of Minnesota, have invented certain new and useful Improvements in Liquid- Fuel-Feeding Devices, ofwliicli the following isa specification.
Myinventionrelates to liquid fuel feedingd'evices and an object is to providea device of this character having 1 a supply reservoir or tank and-a suction tube through which the liquid fuel in the reservoir is fed, combined with means for maintaining asubstantiallyconstant suction head relatively to the lower end of the suction tube'regardlessof'the condition-ofthe reservoir as it varies from a filled to a substantially empty condition. In otherwords, the liquid fuel as it enters the suction tube is substantially under the same pressure no matter what the quantity may be that is contained in the reservoir. An instance in which'my invention-may be employed to advantage is found in lighting plants operated by internal combustion engines in which liquid fuel contained in a supply reservoir is drawn into the carburete-r by the suction of the engine.
When my invention is employed the liquid fuel goes into the suction tube under the same condition 1n regard to pressure substantlally at all tlmes and there 1s no necessity for changing the carbureter adjustment according to the quantity of liquid fuel in the reservoir. Another object is to provide a feeding device of this kind in which the liquid fuel will be confined in such manner as to avoid leakage and danger of explosions. My invention operates without the employment of float feed carburetors with their well-known fire risks due to flooding.
The full objects and advantages of my invention will appear in connection with the detailed description thereof and the novel features embodied in my inventive idea will be particularly pointed out in the claims.
In the accompanying drawings, which illustrate my invention inone of the embodiments which it may assume,
Fig. 1 is a view in vertical longitudinal section. Fig. 2 is a view in cross-section on the line 2-2 of Fig. 1 looking in the direction of the arrow.
Referring to the particular construction shown in the drawings, 10 designates a carburetor of any suitable construct-ion connected to an internalcombustion engine "12. From the lower end of the carbureter' suctlon tube It extends i nto-aclosedtank-or supply" reservoir 16 and terminates adjacent as to: be spacedat different distances from l the bottom thereof for differenhportions of the partition. shown, this partitionincludes a horizontal portion is-and an 1 upwardly-inclincd portion 20. Then-suction tube le extends through the horizontal portion 1S. An airwinlet =0r vent tube--22extends fromthe outside of the-reservoir down through the inclined portion 20, terminating preferably near the highest part thereof. Provision is made for passage of air upwardly through the partition and for passage of liquid fueldownwardly through the partition. In the embodiment as shown, there is a hole 2% for passage of air upwardly and a hole 26 for passage of liquid fuel downwardly through the partition into the space underneath the same. The hole 24% is located at a somewhat higher point than the hole 26. The reservoir is provided The operation and advantages of my invention will be readily understood in connection with the foregoing description. When the reservoir is first filled the liquid fuel will fill thespace underneath the partition and will rise in the vent tube 22. Upon starting the engine the liquid fuel is quickly drawn out of the tube 22 and out of the space 8 underneath the inclined portion 20 of the partition. When the level in the space 8 is reduced below the hole 24: to the position shown by-the dotted line Z, air will enter the main portion of the reservoir through this hole and will break the vacuum which has started to form at the top of the reservoir, with the result that liquid fuel will flow out of the opening 26 in sufficient quantity to maintain the level in space 8 substantially as indicated at Z. The pressure head relatively to the lower end of the suction tube 14; will, therefore, be substantially constant until the reservoir is nearly emptied, since the liquid fuel enters the tube 14 under a head equal to the difference in height between the lower end of the tube 14 and the level indicated at Z. In this arrangement there is no chance for escape of the liquid fuel and danger of explosions occurring is reduced to a minimum.
I claim:
1. A liquid fuel feeding device co1nprising a closed supply tank, a partition in said tank spaced from the bottom thereof at unequal distances at different portions, a suction tube extending into said tank and terminating close to the bottom thereof, and an air inlet tube connected to the space below said partition, the latter being provided with means for permitting air from said space to enter the main portion of said tank and liquid fuel to pass from said main portion into said space.
2. A liquid fuel feeding device comprising a closed supply tank, a partition in said tank spaced from the bottom thereof a greater distance at one portion than at another portion, a suction tube extending into said tank and terminating close to the bottom thereof and below the portion of said partition which has a lesser spacing, and an air inlet tube, connected to the space below the portion of said partition having a greater spacing, said partition being provided with means for permitting air from said space to enter the main portion of said tank and liquid fuel to pass from said main portion into the space below said partition.
3. A liquid fuel feeding device comprising a closed supply tank, a partition in said tank spaced from the bottom thereof a greater distance at one end than at theother end, a suction tubeiextending down into said tank and through the portion of said partition having the lesser spacing, said tube terminating close to the bottom of said tank,
and an air inlet tube extending down into said tank and through the portion of said partition having the greater spacing, said air inlet tube terminating at the underside of said partition, the latter being provided with holes for passage of air into the main portion of said tank and passage of liquid fuel from said main portion into the space below said partition.
In testimony whereof I hereunto affix my signature.
ASHLEY C. BENNETT.
