i SPECIFICATION. forming part of Letters Patent No. 554,308, dated February 11, 1896.

Application filedNovember 22, 1894. Serial No. 529,613` (No model.)

To all ich/m it maty concerne it4 known that DANIEL M. REDMOND, de-

` ceased, late a citizen of the'United States, and

a resident of the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, did in his lifetime invent certain new and useful Improvements in Oil-Holders, of which the following` is a specification, furnished by nie, DANIEL H. REDMOND, a citizen of the United States, residing at Philadelphia, Pennsylvania, administrator of the estate of said DANIEL M. REDMOND, deceased.

One object of the present invention is to z provide an eflicient, reliable and comparatively inexpensive holder for kerosene-oil, benzine, and other inflammable fiuids, which is at all times filled, whereby the formation and collection of explosive gases are obviated, and in which there is no internal pressure, whereby danger of leakage is avoided 3 and to this end the invention consists of the improvements hereinafter described and claimed.

The nature, characteristic features, and scope of the invention will be more fully understood from the following desc1'iption,taken in connection With the accompanying' drawing, forming part hereof, and in which is illustrated partly in elevation and partly in central section an oil-holder embodying' features of the invention. i

In the drawing, 1. is a tank or vessel of any preferred size and shape, and in the example illustrated this vessel is located beneath the surface A B of the `ground, and is provided with an oil-inlet 2 and an oil-offtake 3, both of which extend above the level of the ground, the latter not so far as the former. The oilinlet 2 is or maybe provided at its upper end with a stopper or stop-cock 4. The offtake 3 is provided with a stop-cool; 5.

6 is a pipe or vessel that communicates with the interior of the tank or vessel 1, near the bottom thereof, and that is open at its upper end for the reception ,of a supply of fiuid, as water, heavier than oil, issuing from the supply-pipe 7 and Controlled by the stop-Cook 8, and for the overfiow of such fluid.

9 is a cup adapted to receive the overfiow from the top of the pipe or vessel 6, and to lead the same away through the waste-pipe 10.

11 is a petcock or spigot located below the opening and closing the petcock or spigot 11.

The mode of operation of the above-described apparatus is as follows: The tank or vessel 1 is filled with oil, benzine or other inv flammable material, for example, level with thepetcock 11. For this purpose the petcock 11 may be opened and the oil, benzine or other infiammable material poured into the in'let 2 until it appears at the petcock. During this operation the supply-pipe 7 is closed by means of the valve 8. The pe'tcock 11 is then closed and water is permitted to escape from the supply-pipe 7 and to collect4 in the vessel or pipe 6. The weight of the waterlin the vessel 6 displaces the lighter oil, benzine or other inflammable material and causes it to rise in and fill the vessel or tank 1, until finally a state of equilibrium between the two liquids is established. For example,

- the oil rises to the level indicated by the line a b, and the Water rises to the level indicated by'the line c cl. Under these circumstances the weight of the columns of oill and water balance each other, so that additional water leaving the supply-pipe 7 overfiows from the pipe 6 into the cup 9, and thus escapes from the waste-pipe 10. However, when the cock 5 is opened oil fiows from it by reason of the fact that the level of the oil a b is above it, and the space which was occupied by the oil so drawn oif is immediately filled with water that iiows in through the pipe or vessel 6.

From the foregoing description it will be obvious that the vessel 1 is always full, so' that there are no spaces in which eXplosiVe gases, vapors and the like can collect, and that since the. oil simply remains supernatant or fioating upon the water the apparatus is not subj ected to internal pressure, whereby leakage and its consequent dangers are avoided. Vhen all the oil has been drawn off the vessel 1 is, of course, filled with water. However, this water is expelled during' the refilling operation above described by reason of the fact that the petcock 11 is open, thus re- IOO dueing the heig'ht of the Water column, and the inlet 2 is filled to its top With oil, thus inoreasing the height of the oil column. By inoreasing the height of the top of the pipe (i the Weight of the column of heavier fluid, as Water, is inoreased, so that the level a b of the lighter fluid, as oil, may be raised, thus permitting the stop-Cook 5 and offtake 3 to be placed farther above the ground-line A B. The absence of internal pressure in the vessel 1 permits of the use of a fioat 14 and indeX-rod 15, that is attaohed to the float and Works in a tube 1G, projeoting` upward from the vessel 1, as shown. This float 14 is so weighted or loaded as that it floats on Water and sinks in oil, and thus rises and falls as the line c d rises and falls, and eonsequently eauses the indeX-rod 15 to indioate the quantity of oil contained in the vessel 1. 17 is a oap that may be used for covering` the upper end of the tube 1(3, as required.

It will be ovious to those skilled in the art to .which the invention relates that modifications may be made in details without departing from the spirit thereof. Ilence it should not be limited to the precise construction. and arrangement of parts hereinabove set forth and illustrated in the aceompanying drawings; but,

Having thus deseribed the nature and objeets of the invention of the said DANIEL M. REDMOND, deceased,=what I, his administrator, olaim as new, and desire to secure by Letters Patent, is-

The combination in an oil-holder, With an oil-vessel closed at its top, an immovable pipe open at its upper end and communicating' With the lower portion of said vessel at its other end and provided intermediate of its ends With a petcook, and means for introduoing' Water into the open end of said pipe, of a cup provided with a waste-pipe and eontaining said petcook and underlying` the open end of the fixed pipe, an oil-offtake, and an oil-inlet, substantially as desoribed.

In testimony whereof l have hereunto signed my name.

DANIEL H. REDMOND, Administrator ofihe Eszfm'e of Dan z'eZ III. Redmoml.

In presence of- EVAN J. LEsTER, A. B. SToUG-HTON.
