CHARLES M. HOLLINGSVORTH, OF CLEVELAND, OHIO.
OIL-FEEDING DEVICE FOR VAPOR-STOVES.
SPECIFICATION forming part of Letters Patent No. 448,236, dated March 17, 1891.
Application filed July 14, 1890. Serial No. 358,641. (No model.)
To aZZ whom it may concern:
Be it known that I, CHARLES M. HOLLINGS- WORTH, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio,have invented certain new and useful Improvements in Oil-FeedingDevices for Vapor-Stoves, of which the follwing is a full, clear, and exact description,reference being had to the accompanying drawings, in which-- Figure 1 is a front elevation of a vaporstove having two burners, and Fig. 2is an enlarged vertical sectional view on the line 2 2.
My invention relates to carhureting vaporstoves in which the constancy and regularity of the burnenflame is dependent upon the regularityin the rate at which the liquid hydrocarbon is fed to the carburetor, and it is particularly adapted to and is shown in the drawings in connection with that form of vapor-stove which contains in its construction the sort of gravity-carburetor which is shown in Letters Patent No. 421,834, granted to me February 1 1890.
My invention is in the nature of an improvement on the oil-feeding device described and shown in an application for a patent executed July 10, 1890. In that device means are provided by which a user can regulate the size of the final outlet of the carburetor and other means whereby a suitable pressure of the liquid at the final outlet can be maintained, which pressure is not dependent upon the quantity or height of the liquid in the main reservoir, the result of the combined mechanism being a regular" feed to the carburetor and a consequent constant flame of any desired size at the burner; but it is de-' sirable that vapor-stoves should be so iconstrueted that their success should depend as little as possible on the care and attention of the user; and the objects of my invention are to simplify and cheapen the oil-feeding device, and especially to provide means for antomatically preserving a constant pressure of the liquid at the final outlet to the carburetor, whereby the regulation and control of the burner-flame shall be a matter requiring only slight care.
To these ends my invention consists in the construction and combination of parts herein shown and described, and pointed out definitely in the claim.
Referring to the drawings, L represents a suitable tank or main reservoir, which con tains the supply of liquid hydrocarbon to be vaporized, which reservoir will preferably be made of sheet metal and of cylindrical form. Below the main reservoir is a supplemental reservoir 2, which in the form shown in the drawings is formed directly beneath the main reservoir by means of the partition 3. There is an orifice through this partition, over which is soldered a small casting 4, which has a central orifice through which the liquid passes by gravity to the supplemental reservoir.
This orifice is provided with a tapered valveseat, against which a valve 5 is seated, as hereinafter explained, thus closing the orifice. Over the casting 1 is fastened a piece of wiregauze 6, which prevents foreign particles from lodging in and obstructing said orifice. A small tube 7 extends from the partition 3 to the upper end of the tank 1 and connects the supplemental reservoir 2 with the outer air, and thus affords means forpreservingatmospheric pressure on the liquid in said supplemental reservoir.
To the lower wall of the supplemental reservoir is secured a casting 8, having an orifice through which the liquid flows by gravity from said supplemental reservoir toward the final outlet, through which it passes tothe carburetor.
As many carburetors 9 may be employed as are desired, two being shown in the drawings, each feeding a separate burner 10.
The casting 8 connects with a branch pipe 11, and as many nozzles 12 branch from this pipe as there are carburetors. Each nozzle contains a final outlet from the oil-feeding device, and each is opened and closed by a suitable valve 13.
In order to intelligently regulate the size of the flame at the burner, it is necessary to have means for regulating the size of the final outlet and other means not dependent upon the quantity of liquid, in the main reservoir for maintaining a suitable pressure at the final tially constant pressure by providing means whereby the liquid shall be fed from the main reservoir to the supplemental reservoir until a certain height of liquid in said supplemental reservoir is secured, after which the said height shall be automatically maintain ed. To secure this last result I provide a float 14, located in the supplemental reservoir, which carries a valve adapted to close the orifice leading from the' main to the supplemental reservoir, and the parts are so arranged that when the proper amount of liquid is in the supplemental reservoir the float carries the valve to its seat and prevents any immediate further entry of the liquid to said supplemental reservoir so long as the final outlet remains closed. \Vhen this final outlet is opened, the float is slightly lowered and the liquid is permitted to flow into said supplemental reservoir at substantially the same rate at which it. flows out through the final outlet, thus automatically maintaining a constant level and pressure. The float 14 is made of two pieces of thin sheet metal securely fastened together at their ends, thereby forming a plane-convex circular disk. A tube 15 passes centrally through the float, being soldered thereto at both ends, and one 'end of said tube projects below the float. The valve-rod 5 passes through this tube and a horizontal pin 16, passing through the rod and the part of the tube which extends below the float pivotally secures said rod to the float. By reason of this pivotal connection of the valve-rod to the float the valve-rod will always be seated against the valve-seat in the casting 4 when the float rises, whether the tank L be set vertically or not. The rod projects at both ends from the float, the lower end extending into the orifice in the casting 8, while. the upper end extends into the orifice in the casting 4. These ends of the valve-rod are so long that they do not come but of the orifice in either of the two castings at any time, whether the supplemental chamber is full or empty. Therefore there is comparatively little danger of breakage during shipment, and the valve is sure to seat itself when carried up sufliciently by the float. WVhen the liquid does flow from the main to the supplemental reservoir, it runs down the valvestem through the tube 16 and is delivered into the liquid in said reservoir without any opportunity to find a lodgment on the top of the float. The buoyancy of the float will therefore be constant and its action regular, whereby a uniform level of the liquid is maintained in the supplemental reservoir.
In preparing these stoves for the market an index-finger 17 is usually placed upon the stem of each valve which controls a final outlet, and these fingers are so adjusted that when the valve is turned to a point where this index-finger occupies a certain position a vertical position, for eXample-.a full normal feed to the burner is secured. Thus the proper working of the device is made almost wholly independent of any care or skill on the part of the user.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
In an oil-feeding device for vapor-stoves, a tank having a partition which divides said tank into a main reservoir and a su pplemental reservoir located below the main reservoir, a casting secured to said partition and having a duct through which the liquid flows by gravitv from the main to the supplemental reservoir, a wire-gauze secured to said partition above the entrance to said duct and adapted to prevent the entry of foreign partieles thereto, and a casting secured to the lower wall of the supplemental reservoir, having an orifice through which the liquid flows, combined with a float-valve in said supplemental reservoir having a tube passing centrally through it and projecting below it, a valve-rod passing through said tube and pivotally connected with the part thereof which eX- tends below said float, said valve-rod being extended at its lower end into the orifice in the lower casting and at its upper end into the duct in the upper casting and having a conical upper end adapted to engage with a conical valveseat formed in the upper casting, substantia ly as and for the purpose specified.
