MEANS FOR CONTROLLING FLOW OF LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 570,436, dated October 27, 1896.

Application filed June 4, 1895. Serial No. 551,640. (No model.)

To on whom it may concern.-

Be it known that I, GEORGE O. MOEWEN, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Means for Controlling the Flow of Liquids; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to a novel form of apparatus for burning hydrocarbon oils or other oils, and is designed for utilization for both illuminating and heating purposes.

The present invention has for its primary object to provide a novel form of controlling device or regulator for automatically delivering the oil for consumption which shall be very simple in construction and still very reliable in its governing operation, completely shutting off the supply of oil and avoiding leakage when the burner or burners are not lighted, the construction of my novel form of controlling device being such to regulate the height of the oil in a service-tank and in the fount or founts of the lamps supplied with oil from said tank.

The invention therefore consists in the novel form and construction of controlling device or regulator herein shown and described, and also in the novel arrangement and combination of the same with other parts of the invention, such as will be hereinafter fully described, and finally embodied in the clauses of the claims.

The invention is illustrated in the accompanying sheet of drawings, in which- Figure 1 is a vertical section of a suitable chandelier and lamps provided with a service-tank and illustrating one arrangement of my novel form of controlling device in connection with said tank. Fig. 2 is a vertical sec tion of said controlling device on an enlarged scale, illustrating one form of valve construction; and Fig. 3 is a horizontal section of the same, taken on line 00 in Fig. 2. Fig. 4 is a vertical section of the controlling device, but illustrating another modified form of valve used in connection therewith; and Fig. 5 is still another form of valve provided with a tubular form of piston or valve-stem. Fig. 6 is a sectional view of still another form of controlling device or auxiliary or supplemental service-tank and valve therein.

Similar letters of reference are employed in each of the above-described views to indicate corresponding parts.

In said drawings, 1) designates the main supply-tank, which may be-placed in any suitably elevated position, either within or'with out the building, to supply one or more lamps or burners. Connected with said tank I) by means of a suitable supply-pipe b is a chandelier A, which consists, essentially, of the upper ornamental section a, for securing it to the ceiling, and the pipe a, secured therein and connected by a suitable connection a with said pipe Z), which can be suitably packed or otherwise constructed to prevent leakage at that point. The lower end of said pipe a is screw-threaded, as shown, and is screwed into a threaded boss or collar 0, from which extend suitably-constructed spider-arms 0, having the perforated ends 0 to which is secured, by means of suitable pins or rivets, the service-tank (I. Said tank is provided with a centrally-perforated cover (1, which is arranged around the pipe a and over said boss or collar 0 and has its edge d turned down and over the upper circumferential edge of the service-tank, to which it can be secured in any Well-known manner, as will be clearly evident. Said tank d is also provided in the bottom thereof with a suitable depression (1 for the connection of the chandelier arms or branches (1 which support and feed the founts (Z of the lamps cl.

Of course it will be understood that the form and construction of said service-tank 61 may be varied. lVithin said tank d, I have secured a suitable governing or controlling device for completely and automatically shutting off the supply of oil into the tank cl when the oil rises above a certain level, and the construction of said device being such to automatically open and permit the entrance of a fresh supply of oil into said tank at when the oil has fallen below said level. Said controlling device comprises therein a separate oil-receiving reservoir or chamber 6, which may be of any de sirablc shape and cross-section, and is secured in any suitable manner, preferably within said tank (I, to one of the spider arms 0, substantially as illustrated in Fig. 1. Said reservoir or chamber 6 acts as an auxiliary or supplemental service-tan k,into which the fluid from the main supply-tank b is received, and is preferably provided with a suitable cover a, secured to said chamber in any desirable manner, and is connected with the lower end a of the pipe at by a suitable pipe or tube a, which terminates and is secured in a suitable opening 6 in the side or in any other desirable portion 01' said chamber or reservoir 6. In the bottom of said chamber or reservoir 6 is a suitable opening, and in communication with the same is a stand-pipe or other suitable casting a provided with a longitudinally-arranged duct 6 through which the oil deposited in the chamber 6 can pass and flow into the service-tank (1 when the valve or controller connected with said stand-pipe or the casting 6 is open. Said valve or controller consists, essentially, of a suitable piston or valvedisk 6, having an annular and downwardlyextending rib or flange e, which normally rests upon a suitable packing-ring f, made of any desirable material, and which may be forced into and held in a depression in the top of the stand-pipe or casting a, as clearly sho wn in Figs. 2 and 2). Connected with said piston or disk a is a stem c", which extends down into and through said duct 6 leaving sufficient space for the passage of the oil through the same, and said stem being provided with a bifurcated and perforated end a at the bottom. In place of the stand-pipe 0 (shown in Figs. 2 and 4) said controlling device 6 may be made as indicated in Fig. (3. In said construction the i e a is tapped directly into a tubular portion c having a duct 6, said portion being formed integral with the standpipe portion 6 The fluid passes down through the duct 6, and through an opening 6 in the pipe portion 6'' at one side thereof, as indicated in dotted lines, and finally through the top of said pipe into the tank (Z. The valvedisk 6 on the stem 0 may rest in a conical seat at the top of said pipe or casting 6 substantially as shown, in which case I may dispense with the packing f. Pivotally supported in a suitable bracket g, as shown in Figs. 1 and 2, is a suitable float h, having an arm 72 which is also pivotally connected with the bifurcated end of said stem 6 Said float, which is preferably of the construction shown, but may be made in the shape of a lever or other similar device, is of such a construction that it will rise and fall with the varying levels of the fluid in the tank (1, thereby correspondin gly operating the valve-stem, and hence the piston or valve-disk 6 which is brought down upon or raised from the packing-ring f or its seat at the top of the stand-pipe or casting 6 Thus it will be seen that when the oil in the tank d is at the level indicated in Fig. 1 said valve is closed, but as the fluid is being consumed by the lamps or burners and falls below said level in the service-tank cl, an upward movement of the valve-stem c is the result, causingthe valve at the top of the stand-pipe or casting to be opened and a fresh supply of oil to pass into the tank d, and as soon as the oil therein has again reached its former level indicated in Fig. 1 said valve-disk e is again tightly closed down on the packing-ring f or upon the valve-seat at the top of the pipe or casting 6 thereby completely shutting off the supply of oil into'the tank cl until a fresh supply is needed. In lieu of the construction of valve illustrated in said Fig. 2, the casting 6 may be made in the manner of a hollow cylinder and the packing f can be secured directly to the under side of the valve-disk or piston a, being brought down upon the surrounding edge of the said cylinder when the valve is closed to shut off the supply of fluid, as clearly illustrated in Fig. 4. If desirable, said valve-stem 6 may be made hollow, as indicated in Fig. 5, being provided with suitable perforations e, through which the fluid can flow into said hollow stem and finally down into the tank cl, as will be clearly un derstood from an inspection of said Fig. 5. By this arrangement of the valve-disk e at the top of the pipe or casting e the column of oil in the chamber or reservoir 6 will by its own pressure act 011 the top of said disk, and in addition to the weight of the valve-operating mechanism will help to maintain said. valve-disk closed tightly down upon or against the packing-ring f or upon its seat when the level of the fluid in the tank cl is below the level indicated in said Fig. 1, thereby securing an absolute stoppage of the flow of liquid from the chamber 6 into the tank (1.

Of course it will be evident that my novel form and construction of controlling device is applicable to many other purposes and apparatus for automatically controlling the flow of liquids from one reservoir or a pipe into a second reservoir or pipe, and I therefore do not limit my invention to its use in connection with lamps for burning hydrocarbon or other oils. It will also be evident that many changes of construction may be made in the details of the arrangements and combinations of the parts herein shown without departing from the scope of my invention, and I therefore do not limit my invention to the exact arrangements and combinations of parts herein shown and described.

Having thus described my invention, what I claim is- 1. In a device for controlling the flow of liquids, the combination with a service-tank. and means for conducting liquid into the same; of a separate chamber or reservoir arranged within said tank; a stand=pipe in said chamber or reservoir leading from the same into. said service-tank; a valve at the top of said stand-pipe held closed by the pressure of the column of liquid 3 and means connected with said valve and operated by the rise and fall of the liquid in the service-tank to control the movement of said'valve.

2. In a device of the class described, the combination with a service-tank and means for conducting liquid into the same; of a chamber separate from and Within said tank;

a stand-pipe in said chamber communicating with the service-tank a valve for said standpipe held closed by the pressure of the column of liquid; a float; and means connecting said float with the valve.

3. In a device of the class described the combination with a burner of a service-tank GEO. G. MCE'WEN.
