FUEL-FEEDING DEVICE.

Specification of Letters Patent.

Patented June 3, 1919.

Application filed July 23, 1918. Serial No. 246,320.

To all whom t muy concern:

Be it known that I, lVILLmM J, EMBS, a citizen of the United States, residing at Iron River, in the county of Iron and State of Michigan, have invented certain new and useful Improvements in Fuel-Feeding Devices, of which the following is a specification.

This invention relates to improvements in fuel feeding devices for liquid fuel burners and it is the principal object of the invention to provide a novel form of reservoir fuel feeding device particularly adapted for use in connection with oil burner stoves of the lamp type, whereby the reservoir thereof can be easily and quickly filled with oil without inverting the same as is necessary with the prevalent forms of similar devices at the present day.

Another and equally important object of the invention is to provide the device with novel'vent means whereby the air is allowed to escape from the reservoir when reservoir is being filled through a tube opening into the bottom of same.

` Other objects will be in part obvious and in part pointed out hereinafter.

The improvements in the details and arrangement of parts will be apparent from an inspection of the accompanying drawings when considered in connection with the specic description hereinafter contained and wherein a preferred embodiment of the invention is disclosed for the purpose of imparting a full understanding thereof.

In the drawings:

Figure l is a vertical longitudinal section through the improved device.

Fig. 2 is an end elevation thereof, and

Fig. 3 is a horizontal section through the same.

Referring to the drawings, r represents the reservoir of the improved fuel feeding device, and c the ordinary form of oil cup or receiving receptacle, which as will be noted, is arranged therebeneath and has communication with the burner proper of the stove, not shown by' way of a conduit c.

Formed in the bottom of the reservoir r is an outlet opening having a neck l extending therefrom, the lower portion of whichV is `constricted as at 2 to form an effectual valve seat, to receive a conical valve 3 therein, said valve having its upper portion engaged by one end of a coil spring Il, the remaining end of which, as will be noted, bears upon a trees pin 5 positioned adjacent the outlet opening. The valve 3 may be and preferably is provided with an elongated stem portion 6 adapted to beengaged, at times, with the bottom of the oil cup c whereby to effeet the unseating of said valve and the re sultant flow of fuel'from the reservoir r into the cup c.'

Extending from the bottom of the reservoir 7" is a vent pipe 7, itvbeing noted that the upper end of said pipe is extended to a point in proximity to the closed top of the reservoir and, obviously, serves to permit the escape of air from the reservoir when the reservoir is raised and is bein@ filled.

A Iilling tube 8 is arranged adjacent one end wall of the reservoir r and has its lower end curved upon itself as at 9 and extended through an opening formed in the adjacent portion of the reservoir bottom; the upper or remaining end of the filling tube being beveled as at 10. for a purpose which will be presently described. As will be understood, it will be noted the curved end 9 of the tube 8 is arranged at a point below the level of the fuel in the cup c. In this connection, it may be noted that aV portion of the oil cup c is recessed as at l1 to permit the passing of the curved lower end 9 of the filling tube 8 thereby.

As means for moving the reservoir r vertically with relation to the oil cup c, standards l2 are engaged with a portion of the frame of the oil stove, not shown, and, as shown in Fig. 1, certain of the same are pivotally engaged with the. bell crank shaped extremities of a substantially U-shaped lever 13, said extremities being pivoted to the reservoir r at 13', while the remaining standards are pivotally engaged by links 14C having pivotal -connection at l5 with the reservoir 7'. In this way, itis obvious that when the lever 13 is moved downwardly to the position shown in dot and dash lines in the Fig. l, the reservoir r will be moved upwardly from the cup c, thus allowing the conical valve 3 to Vbe seated on the constricted portion 2 of the outlet neck l and in this way prevent the flow of oil from the reservoir into the cup. It is to be further noted, that when the lever 13 is in its uppermost position, as shown in dotted lines in the Fig. 1, the lateral portion thereof is engaged over the beveled upper end of the filling tube 8, thus forming an effectual closure therefor, while the positioning of the bell crank shaped extremities thereof and the links 14: is such as to eect the lowering of the raser voir r into engagement with the oil cup c. By reason of such engagement of the reservoir with the oil cup, the extended stem 6 of the valve 3 will engage the bottom of the oil cup and consequently, will move said valve 3 upwardly from the constricted portion 2 of the neck 1, hence, permitting` liquid fuel to flow therefrom into the cup. As the level of the liquid fuel in the cup c reaches the lower' end of the vent pipe 7 and the constricted portion 2 of the outlet neck 1, the same will be closed and the flow of air upwardly therethrough into the reservoir r will be discontinued. Consequently, the flow of liquid fuel from the reservoir will be interrupted. However, as the fuel is exhausted from the cup c and the level thereof again falls below the adjacent end of the vent pipe 7, a further supply of fuel will be discharged from the reservoir into the cup.

As it becomes necessary to lill the reservoir r, it vis only necessary to move the lever 13 downwardly to the position shown in dot and dash lines, whereupon the conical valve 3 will be caused to seat in the constricted portion 2 of the neck 1, the constricted portion 2 and the lower end of vent pipe 7 will be raised above the surface of the liquid fuel in oil cup c, the liquid fuel in vent pipe 7 will drop into cup c, while the lateral portion of lever 13 will be disengaged from over the upper end of the filling tube S, thus allowing the spout or nozzle of the dispensing can to be placed therein. As the liquid fuel is poured into filling tube 8, it will pass up into reservoir o, and the air in reservoir r will be forced out through vent pipe 7.

Manifestly, the construction shown is capable of considerable modification and such modiiication as is within the scope of my claims, I consider within the spirit of my invention.

I claim:

1. In a fuel feeding device, a movable reservoir having outlet means in its 'bottom, a receiving receptacle arranged beneath said reservoir, valve means in the outlet operable upon movement of the reservoir with relation to said receptacle, a vent pipe extending from the reservoir to a point adjacent the outlet means, a filling tube arranged adjacent one end wall of said reservoir and communicating with the bottom thereof, standards arranged adjacent the reservoir, a. substantially U-shaped lever having the extremities thereof formed at substantially right angles thereto pivoted to the upper ends of certain of said standards, and links pivoted at certain of their ends in the remaining standards and to the res-v ervoir.

2. In a fuel feedingdevice, a movable res` ervoir having outlet means in its bottom, a receiving receptacle arranged beneath said reservoir, valve means in the outlet operable upon movement of the reservoir with relation to said receptacle, a vent pipe extending from the bottom of the reservoir to a point adjacent the lower end of the outlet means, the upper end Vof said vent pipe extending to a. point in proximity to the closed end of the reservoir, a lling tube positioned adjacent` Aone end wall of the reservoir, and communicating with the bottom thereof, standards arranged adjacent the reservoir, a substantially U-shaped lever having its op posite extremities disposed at right angles thereto pivoted to certain of said standards and to the reservoir, and links pivoted to the remaining standards and said reservoir.
