LIGHTING ATTACHMENT FOR VAPOR-LAMPS.

srncrrrcarron forming part of Letters Patent No. 629,227, dated July 18, 1899.

pplication filedlliarch 22, 1899.

designed for attachment to oil-gas burners of that kind in which a generator is heated by. the flame of the burner; and it comprises, essentially, a carburetor of special construction which is designed to furnish a limited quantity of gas that is applied to heat the 'generatorto working condition before the-ordinary or service generator is brought into use.

My invention comprises certain novel features, which will be herein after described and claimed.

Reference is to be had to the accompanying drawing, forminga part of this specification, in which the figure is an elevation showing. the essential parts in section.

I have here shown my device as applied to a lamp; but it is obvious that it may be applied equally well to burners, whether used for lighting or heating purposes. I have also shown it as applied to a single generator and burner; but it will be evidentthat it may be applied to any reasonable number ofburners, said use of the device being hereinafter more fully described. 7

The lamp consists of a tank A, designed to hold the oil, a generator G,which is connected with the oil-feed pipe D and is controlled by a valve E, a mixing-pipe F, and a burner .H,which is located beneath the generator G.

These parts may be of any ordinary or preferred construction, the particular construction thereof not forming any part of 1nypres-- ent invention.

The tank A is made sufiiciently large so that it need not be filled more than half-full of oil. The tank A is provided with a. false bottom 0, which provides an annular space about the lower portion of the tank adapted to act as a seal for the bell B. This bell is of such size as to work freely within the tank and of such length that it may be raised from its ordinary position; In order that it may be operated conveniently, it has arod Q'eon- Serial N0.'710,069. No model.)

nected thereto, which passes through a guide opening in the upper end of the tank A and is provided with a ring or other suitable means by which itmay be operated; By taking hold of this ring the bell maybe lifted to the top of the tank. The false bottom 0 extends above the bottom of the tank A a distance about equal to the upward movement of the bell, and theieed-pipe D extends a short distance above the said false bottom. By this construction the bell will be always sealed, and sediment is prevented from passing through the pipe D to the generator. A pipe I passes through the bottom of the tank'and extends upward until its upper end is above the oil-level. The upper end of this pipe has a wire hood J secured thereto, said hood beingcovered with a layer K of absorbent or fibrous material. This absorbent layer is connected with a wick L,which extends downward and by which means the absorbent material K is kept constantly saturated with oil.

The pipe I extends downward and has its end terminating in a burner which is so located that the flame thereof will heat the generator G. The pipe may, as herein shown, be branched at its lower end,having two branches M and N, each of which is provided with a controlling-valve O or O'.' The branch M is shown as provided with a burner P, which discharges its flame .directly upon the generator. The other branch N is shown as connected into the mixing-pipe F, from whence the gas passes to the ordinary burner H of the lamp, which is located beneath the genorator G and heats the same. Either form of vconnection for the pipe I may he used, as it is immaterial whether the carbureted air is supplied to the ordinary burner H or to aburner I. The construction adopted will depend upon the circumstances of the case.

The oil is supplied to the tank A through the pipe a or other suitable filling device, said pipe being closed tightly by a cap a. or other equivalent device.

The operation of my device is as'follows z the desired blue flame may be obtained. In case such a burner is used forlighting apparatus in connection with-an incandescent mantle it is'not possible to supply the oil directly to said burner, as it would soot up the mantle and destroy its usefulness. It is therefore necessary to supply an independent heating means for said generator. If the burner P is to be used with my device, the valve connecting the pipe I with the mixing-pipe F is closed and the valve 0 is opened. The bell B is then raised to the top of the tank A. WVhen this is done, air will rush into the bell through the pipe I and is ,charged with oil-vapor by passing through the absorbent material K, which covers the hood J. If the bell is raised with sufficient rapidity and the opening through which the rod Q passes is sufficiently small, the air above the bell B will be compressed somewhat, which will act upon the level of oil outside of the bell so as to lower it, forcing the oil inside the bell, and if this compression raises it a sufficient point the air will be forced beneath the lower edge of the bell and under the bell. The device will work satisfactorily in either case and in fact will operate in the manner just described to force the air beneath the lower edge of the bell if the valve 0 is closed. WVhen the bell 3 is released, it will descend slowly under the influence of gravity and force the imprisoned air through the layer of absorbent material K, which is charged with oil, thus adding more of the vapor of the oil to the air and makingit inflammable. As gas is discharged from the burner P it is lighted-and heats the generator G. The bell B is made of such a size as to supply a sufficient quantity of gas for properly heating the generator G. WVhen the generator has been sufficiently heated, the valve E is opened and oil is supplied to the generator in the ordinary manner. The bell B falls until it rests upon the bottom of the tank and the gas contained therein has been entirely discharged.

Then the connection N is employed, discharging the gas into the miXing-tube-F, the valve 0 is closed, and the gas then passes downward to the burner H,where it is lighted. The generator is then heated from its own burner. This method of lighting the lamp gives a light immediately and may in some cases be preferred.

It is evident that a single carbu'reter may be used to supply gas to more than one burner, if desired, as in thecase where a stove is supplied with more than one burner. In this case the pipe I is supplied with as many branches as there are burnerssuch, for instance,if there were two burners one burner would be connected with the branch corresponding with the branch M and the other corresponding with the branch N, each branch being provided with a controlling-valve, as the valves 0 and 0. If it be desired to light only one or a portion of the burners, the valves leading to all the burners, except those which are to be lighted, are closed, so that the flame of the burner will not be sucked out.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. The combination with a burner, and a generator, of an oil-tank, a bell Wholly within the tank and sealed by the oil therein, means for raising the bell, a pipe leading from the burner up into the tank above the oil-level therein, and Within the bell, an absorbent material in the bell and through which the air is caused to pass and a supply-pipe leading from the generator and extending up into.

the tank a distance about equal to the upward movement of the bell, substantially as described. I

2. The combination with a burner, and a generator, of an oil-tank having a false bottom therein and forming an annular space about the lower portion of the tank, a bell wholly within the tank and having its lower portion in said annular space, means for raising the bell, a pipe leading from the burner up into the tank above the oil-level therein and within the bell, and provided with an absorbent material and a supply-pipe leading from the generator and extending up into the tank a short distance above the false bottom thereof, substantially as described. 3. The combination with a burner, and a generator, of an oil-tank having a false bottom forming an annular space about the lower portion of the tank, a bell wholly Within the tank and having its lower portion in said annular space, means for raising the bell, a pipe leading from the burner up into the tank above the oil-level therein and provided with a hood of absorbent material, and a wick attached to the hood, and a supply-pipe leading from the generator and extending up into the tank a short distance above the false bottom, substantially as described.
