1,039,991. Specification of Letters Patent. Patented Sept. 24, 1912.

Application tiled July 10, 1911. Serial No. 637,705.

To all whom 'it may concern:

.Be it known that We, l/VILLTAM A. Boven and SAMUEL FISHER, citizens ot the United States, residing at Gas City, in the county otGrant, State of Indiana, have invented a new and useful Cement Reservoir, of Which the following is a specification.

It is the object of the present invention to provide a storage tank or reservoir for oil, so constructed that seepage of the oil through the Walls of the reservoir, Will be? prevented.

A further object of the invention is to provide an oil reservoir, the oil in which willbe entirely surrounded by bodies oi' Water, thereby preventing the evaporation of the oil.

A further object of the invention is to provide novel means for supplying Water to the tank or reservoir, and to` provide means for maintaining a circulation of the water.

AA further object of the invention is to provide anf oil reservoir or tank ot un usual strength;

With the foregoing and other objects in view Which Will appear as the description proceeds, the invention resides in the cornbinationv and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made Within the seope 4of what is claimed without departing from the spirit of the invention.

In the aecolnpanyingd awings,-Figure l shows the invention in top plan, the roei" ot" the reservoir being,` removed; and Fiji'. 2 in a fragmental vertical 'transverse section oi the reservoir.

The reservoir may be iii'tshioned in a variety ot' ways. It desired, a foundation l, .terably of concrete, may be fashioned, and upon the foundation l may be superposed an outer wall 2 and an inner Wall 3, these walls 2 and being likewise fashionedr tlf 'om concrete, and being` suitably:reinforced by metallic niesh work, or the like, as shown at 4. The specific material from which the walls and thefoundations are made, will vary, but they are pre'lei-ably` monolithic structurel'. For a purpose to be set t'ort-h hereinafter, the upper edge olE the inner wall .'l is sjiaeed, shown at 5, below the upper edge of theouter'wall il The outer wall Q is reintorced by buttresses t3, plated as closely too'ether as may be desired. The walls 2 and il are connected by transverse stay rods 7, terminally ext-ended into the The Stay rods 7, between the Walls 2 and 3, are si'lrrounded by concrete or the like, as shown at S.

rlhel bottom of the reservoir may be constructed variously. In the present instance, rthe bottom consists ofa layer of concrete 9, rupon which is su perposed a layer of asbestos i0, covered hy a layer ot grout il; although these structural details, obviously, may be departed fron'1. The layer of asbestos l0 Serves to prevent sudden changes in the telnperature oi the contents of the reservoir, due to terrestrial temperature ehanges.

The roof of the reservoir is vsupported upon the outer walls 2, the roof being' constructed as the exigencies of the ease may demand. ln the present instance., the roof consists ot a layer of concrete, denoted by the numeral l2, and reinforced, as shown at ill., the roof being provided with an upstandingg peripheral lip l5, having;- a tunetion which will be forth hereinafter. Access had to the interior of the reservoir, 'for the pui'poee oi ascertaining the tillage, through a seattle, oiI any desired form, and denoted by the .numeral l0. Ui' these Scuttiles '16, there may be any number. The rootl is supported by struts, one oi which appears in Fig. Q, and is there denoted by the numeral 17, the strut i7 being supported `upon a lsuitable. foundation lS.

'.lhe iaittoni ofthe reservoir is normally covered by a layer oi wat er, and the space between the walls 2 and il likewise filled with wat-er. 'lo provide for the introduction ot the water into the places speeitied, any desired number of water .supply pipes may be provided, one of which, denoted ,by the numeral 19, appears in'Fig. l. The ivator supply pipe 19 is equipped with a branch 9.0 which discharges between the walls Zand 3, another branch 21 ot the pipe 19, discharging' within the inner wall Through water, as shown at 3G; and through the Ined i `um ot thtl branch 2l, a layer of water 3ft may he deposited upon the bottom oif the reservoir. rEhe branches 2() and 2l. are equipped with eut-oil valves 79 buttressee (l, as clearly shown in Fig. l.

the medium oli the branch 20, the space be-v tween the walls and 3 may be filled withY upon the layer of l the oil 35, and int-o the water 3-l 'einer a branch 24- o eninfr l: D

25, there are cutoff valves 2G. The reser voir may be equipped with any number ot' drain or discharge pipes, and Vit may be stated that the specific means shown for supplying water to the structure, andtor removing the water therefrom,may be taken as typical of any means for securing the de sired results.

A layer of oil, shown at 35, is deposited water 3l, through the medium of a series of oil inlet pipes 27, positioned as may be desired. In the present instance one of the pipes 27 is shown in Fig. 2, as entering the top'of the reservoir. The oil 35 may be removed from the reservoir, through a series of pipes, one of which is shown at QS in Fig. Q.

Located at any desired point with respect to the reservoir, is a pump 2t). From one side ot' the pump 29 a branch pipe 30 extends downwardly into the reservoir, below which is upon the bottom ot the tank. From the other side of the pump 29 a branch 31 discharges between the walls 2 and 3.

The water 34 upon the bottom of the tank, and the water 3G between the walls 2 and 3 may be heated by any suitable means. In the present instance, noting Fig. 1, a steam supply pipe 32 is shown as entering the space between the walls 2 and 3, for the pur-Y -pose above specilied; another steam supply pipe 33 passing through the walls 2 and 3, adjacent the bottom of the tank.

In fashioning t-he walls 2 and 3, and in tashioning the bottom of the reservoir, care will be exercised to render the reservoir oil tight. It is found, however, that this .result is ditticult to attain, oil readily passing through a wall which water will not permeate. Since the bottom of the reservoir is eoveredby the layer 34 of water, the oil 35 in the reservoir cannot seep away downwardly. Moreover, since the inner wall 3 is surrounded by the wall of water 36, the oil 35 cannotseep away stated at this point that, when a device constructed as hereinbefore set forth, was tested, there was noseepage M the walls 2 and 3; whereas, a-tcr the Water 36 was drawn away, the oil appeared upon the outer Asurface of the wall 3 after the space o'f-a few hours'. lThe invention makes it possible to construct the Walls of the res` water jacket about 'the walls serving to prevent seepage of oil ervoir relatively thin, the

therethrough, in spite ofthe thinness of the Walls.

In order to prevent an evaporation of the laterally. It may be ot' oil through vcrsely,

oil 35, the root1 of the reservoir is Hooded being retained by the lip 15; and, if desired, means 100 may be provided for maintaining the Water 3T constantly moving, so that the water will overllow thellip 15, and run down the outside of the outer wall 2. Thus, the entire reservoir will be adequately cooled, and evaporation.may be prevented.

Should oil seep through the wall 3, the oil which inds its way between the Walls 2 and 3 will rise to the top of the massof water 3G between the walls, the oil accumulating at the top of the water 36, as shown at 33. It the pump QE) be put into operation, the water 3l will be drawn from the bottom of the reservoir, through the branel 30, and discharged through the branilii 31, into the space between the Walls 2 and 3, below the layer of oil 38, Which has accumulated upon top of the Water 36. The layer of oil 33 will thus be displaced, and pass `over the upper edge 5 of the inner wall 3, the water passing over the edge 5, alongwith Ythe oil, sinking to the bottom of the reservoir. It may be Stated that When the wall 3 is waterjacketed, as hereinbefore described, the seepage of oil'through the wall 3 will'be very slight. In an oil tank having an extent ot' several acres, it may be desirable, however, to return accumulated oil shown at 38, to the interior of the reservoir; and to effect this result, the pump 29 may be operated; it being recalled that the pump Qt) is typical of any suitable means for displacing the water 3G which stands between the walls 2 and i Having thus described the invention what is claimed is: I I
