AUTOMATIC RESERVOIR FORQVOLATILE OILS.

SPECIFICATION forming part of Letters Patent No. 250,041, dated November 22, 1881.

Application filed March 7, 1881.

To all whom it may concern:

Be itknown that I, HERMAN FRITZ,of Cleve land, in the county of Guyahoga and State of Ohio, have invented a new and useful Improvement in AutomaticReservoirs for Volatile Oils, &c.; and I do hereby declare that the following is afull and exact description of the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon.

This invention relates to certain improvements in reservoirs or supply-vessels for that class of stoves or lamps in which the volatile hydrocarbons such as naphtha, gasoline, and the like-are to be burned directly for the pro duction of gas or light, or to be converted into vapor to be burned for such purposes. In the use of such hydrocarbons accidents are liable to happen, owing to the volatility of the material employed, and the liability of the formation of combustible vapors, which are apt to escape from the reservoir or supply-vessel, and where a light is contiguous to the same establish a communication between the light and reservoir, which will result in an explosion in most cases, asthereservoir,upon beingemptied, takes in a proper equivalent of atmospheric air. Such accidents almost invariably occur in filling the reservoir or supply vessel while the burners are lighted, the entering liquid in such cases forcing out the collected vapor in the reservoir,which, by its specific gravity, falls to the burners below, and, becoming ignited, communicates the flame to the interior of the reservoir or vessel and explodes the contents.

The object of my 1nvent-1on is to obviate the danger above mentioned by so constructingthe reservoir or supply-vessel that when it is required to fill it it will necessitate its removal from the pipes leading to the. burners, while such removal will automatically close the eduction-passage of the liquid and open the fillingaperture at the top simultaneously, and vice versa when the reservoir or vessel is secured in place.

My invention consists in the combination, with the reservoir for holding and supplying volatile oils to the pipe communicating with one or more burners, of a nozzle or part containing the oil-supplying orifice, having a socket (Modeh) provided at its top with a recess forming a drip-cup, said nozzle extending below the res ervoir, as hereinafter set forth.

The invention also consists'in the combination, with a reservoir for holding and supplying volatile oil to a pipe communicating with one or more burners, and having suitable feet or a suitable base for sustaining it in a vertical position when detached for filling, of a nozzle or part projecting through the reservoir, provided with an oil-supplying orifice and a socket forming a drip-cup, all as hereinafter shown and described.

In the drawings, Figure 1 represents a vertical sectional view of my invention. Fig. 2 is a top view. Fig. 3 is a view of the coupling and flange detached from the reservoir. Fig. at is a top view of the coupling by which the reservoir or vessel is connected tothe tube leading to the burner or burners. Fig. 5 is a side elevation of the valve and valve casing and rod for operating the valve, a portion of the rod being shown as broken oft"; and Fig. 6 is a perspective view of the coupling which connects the reservoir with the supply-pipe.

The letter A indicates the reservoir or supply-vessel, which may be constructed of metal or other suitable material, of cylindrical or any other desired shape.

B indicates a valve-casing, which is made in the form ofa hollow conic frustunnwith a flange, O, which may be secured to the edges of the central opening at the bottom of the reservoir or vessel by any suitable means that will form a liquid-tight joint. The said flange is provided with downwardly-exteuding shouldered lugs D, the shoulders of which are adapted to engage the inclined or cam flanges E on the coupling F. which is connected to the tube Gr, leading to the burner or burners.

The letter H indicates a valve, which, in the present instance, is in the form of a conic frustum, and is adapted to fit and turn within the valve-easin g B. The valve projects through the bottom of the vessel and an openingin the flange O, and terminates in an angular extension, at, which may be a portion integral with the valve, or may be a nut fixed thereon by a suitable key-fastenin g. This extension or prolongation of the valve, which may be termed a nozzle, has its seat in a seat, 1), formed in the coupling, with a suitable packing,c, interposed between the end of the said extension a and seat b, in order to form a close joint and prevent the escape of oil or gas. The coupling is further provided with a concavity or recess, (1, in order to form a drip-cup that is to collect and retain any oil that may escape from the interior of the reservoir while detaching it for thepurpose of charging. The said valve is also provided with a vertical passage, H, and a transverse passage, I, the latter being so constructed and arranged that it can be brought into connection with a transverse passage, K, through the wall of the valve-casing. It is preferable that the opening in the valve be longer than the opening in the valve'casing, so as to insure a full coincidence between the two openings without special observance of the operator. The said valve has connected to it a vertical rod, L, which extends upward through the top of the reservoir or vessel A, and is rigidly secured to a suitable plate or semicircular cover, M, which, in the present example, is seated on the top of the reservoir, and is adapted to partially rotate thereon, being limited in its movement by a suitable stop or stops. The said cover M is located within a cylindrical chamber, N, at the top of the reservoir A, and is so arranged as to cover the opening through which the rod L passes, and cover and uncover an aperture, P, in the top of the reservoir as it is moved by the vertical rod, as more fully hereinafter specified. The apertureP is providedwith down wardly-turned edges,which form a seatfora float-valve, R, which is located in a perforated or slotted cylinder, S, extending downward from the top of the vessel A to near the bottom. The said cylinder communicates with the reservoir through the perforations or slots, and thus forms a passage for the introduction of the liquid with which the reservoir is to be charged, being adapted toreceive the liquid from the chamber N, through which the apparatus is filled, the said chamber being provided with a removable cap, T, for the purpose. The valve it is provided with a valve stem, U, which passes loosely up through a tube, V, in the top of the vessel, and through the removable cover of the reservoir, in such manner as to guide the valve in its movementand close itagainst the downwardlyturned edge at the aperture P, and thus close the reservoir or vessel when filled.

The operation of my invention is as follows: In its normal condition, or when filled, the reservoir or casing will be in position as indicated in Fig. 1, withthe horizontal passage in the valve in conjunction with a transverse passage in the valve-casing, which will permit the liquid to flow freely to the burner. WVhile in this position the inclined flanges, bearing against the depending lugs on the flange of the valve-casing, will keep the coupling securelyin its seat and form a liquidtightjoint.

While the communication is thus established below, the cover will close the filling-aperture at the top. When it is desired to recharge the reservoir, after becoming empty, in order to open the filling-aperture it will be necessary to turn such reservoir untilthe cover has passed away from such aperture. This closes the valve below and releases the reservoir from the coupling, necessitating its removal from the vicinity of the burners during the operation of charging, and thus obviating all tendency to accidents and to enable the reservoir to maintain itself in an upright position when detached and removed from the supply tube or pipe, it is provided with suitable supports or legs.

1 do not claim in this application, first, combining with the reservoir or supply-chamber of a vapor stove or lamp a valve-casing and a valve having an annular prolongation extending through the bottom of the reservoir, the depending legs, and the coupling having inclined or cam flanges adapted to be secured to the valve by the lugs, whereby the valves will be automatically opened in the act of applying the reservoir to the coupling and closed when detaching therefrom; second, combining with the reservoir, its valve-casing, and valve having an angular prolongation, the depending lugs and coupling, the vertical rod and cover, the latter being adapted to open and close a filling-aperture at the top of the reservoir; third, combining with the reservoir, its valve-casing, and valve having an angular prolongation, the depending lugs and coupling, the vertical rod and cover, the latter being adapted to open and close a filling-aperture at the top of the reservoir simultaneously with the closing and opening of the valve below; fourth, combining with the reservoir the valve having an angular prolongation extending beyond the valve-casing, the rod for operating the valve, and the detachable coupling having an angular socket and a concavity or recess to form a drip-cup; fifth, combining with the reservoir the chamber arranged on the top thereof to serve as a funnel for filling the reservoir, and an inclosure for the plate that covers the filling-tube and the opening through which the valve-rod passes, said chamber being provided with a cover having an opening through which the rod of the float passes. These features are made the subject of an application for patent filed by me June 17, 1881; but

What I claim, and desire to secure by Let tcrs Patent, is-- 1. The combination, with the reservoir for holding and supplying volatile oils to the pipe communicating with one or more burners, of a nozzle or part containing the oil-supplying orifice, having a socket provided at its top with a recess forming a drip-cup, said nozzle extending below the reservoir, substantially as described.
