Application tiled September 19, 1921. Serial No. 501,755.
'/"o nl] vl'io/n. if 11u13/ Pmi/Fern.:
le it known that l, O'rro S. lliavrii, a citizen oll the [lnited States, and a resident of Chicago. in the county of Cook and State of Illinois, have invented certain new and usel'ul Improvements in Storage Tanks, of which the followingis a description, reference heine had to the accompanying drawing'. which forms a partI of my specification. My' invent-ion relates more particularly to storage tanks for oil comprising a molded monolithic structure of hydraulically setting or cementitious material which is adapted to he sunken or buried in the ground. with the exception of the necked orifice; and the invention has for its object the provision ot' a structure or tank provided with an inner lining or easing impervious to oil; while the inner end of the neck ol' the tank is intended to be provided with an inner top or closure member which is provided with a. tillinglr tube or orifice; to hold or properl \Y support a suitable pump, whereby the oil may be forced from or pumped out ol the tank; and which inner top or closure member is also provided. with a `gauge or measuring,Y element where by to determine the aniount of oil or liquid within the tank. The objects and advantages of my invention will all be more readily comprehended from the detailed description of the' drawing', wherein z- .Figure 1 is a vertical sectional view of one form of my improved tank.
liie'ure is a similar view illustrating a modified form.
Figure 3 is a partial top plan and sectional view with the outer cover 0r closure member removed.
M y improved tank comprises an outer wall or shell 1() of suitable hydraulically setting or cementitious material, such as cement and an aggregate, molded to form a monolithic structure comprisingv a bottom and cylindrical sides having;l atop portion which terminates in the upwardly disposed neck. or dome l l which is adapted to extend above, the surface of thoground while the main portion of the` tank is buried or located in the ground as illustrated in the drawing; the shouldered top permitting" the soil to be placed thereon and thus overcome the lendency ol the. tank to work its way upward.
'lhe cementitious structure is provided with an nnerwall or shell 12 of sheet metal,
or other suitable material impervious to oil; the inner shell being preferably continuous througliout the bottom and side walls as well as the top of the tank about the' neck or dome thereof. During the moldingV of the monolithic structure (which is molded about the inner shell or tank 12) the inner shell or tank 12 is provided at the top about the oriiiee therein, with a ine-tallic ring or flanged band 13, preferably of the Z-shape configuration in cross section, placed so as to have one flange disposed downwardly within the orifice of the inner shell or wall 12, while the other flange or portion is disposed upwardly and adapted to be embedded in the hydraulically setting or cementitious material, as shown at 111 in Figure 1. In this manner the annular band or 'ring 13 is not only securely held in place, but the downwardly disposed flange or portion 15 will firmly hold the inner shell or wall and reenforce the upper .crit-leed portion thereof; while the intermediate hori- Zontally disposed portion will provide a suitable shoulder and support for the metallio shell or impervious lining 16 constitutingthe inner wall for the neck 11 of the tank.
The upper end of the neck 11 is provided with a metallic ring 17, the lowerv side whereof is provided with downwardly eX- tending flanges 18 and 19 disposed adjacent the outer and inner perimeters, respeetively,. of the ring and these flanges are preferably embedded or partially so, in the eementitious material or outer easing 10. The inner flange 19 is slightly removed from the inner perimeter of the ring 17 so as to leave a space or shoulder of width commensurate with the thickness of the metallic band or shell 16 in the neck of the tank. lVith the overlapping portion at the inner periineter of the ring 17 and the horizontally disposed shoulder of the ring 13, Iit is apparent that the liningor shell 16 will be .firmly held in place 'against any displacement. The ring` 17 may bc of the skeleton formation, more clearly shown in Figure 3 and is provided with the laterally disposed lip or lug 20 at adiametrically opposite point with a pair of spaced lugs' or lobes 21. This ring 17 is adapted to receive a suitable lid or cover 22. preferably of metal, Vprovided at one side with the downwardly and inwardly bent portion 23 which is adapted to engage beneath the lipor lug 20; while the lid or cover 22 ata diametrically opposits point is provided with downwardly disposed lobe 24fadapted to extend between the spaced lugs 21. The downwardly disposed lobe. 24e is apertured as shown at 25 to receive a suitable lock. `With this construction, it is evident that when the portion 23 is fitted over the horizontally disposed lug of the ring 17 and a suit-able lock passed through the aperture 25 of the lobe 24, that the cover or lid 22 will be firmly locked in place and access to the tank made impossible, as the lobes 21 with lobe 24 fitting therebetween will prevent rotation of the cover.
The inner lower end of the neck 11 is provided with a plate or cap 26, preferably of metal, which rests on the horizontally disposed shoulder provided by the ring 13; the plate providing an inner closure or cap which will prevent material or foreign mat-` ter falling into the Atank when the outer closure member or c'ap 22 is removed. The inner cap or plate 26 is provided with an aperture for the reception of a suitable gauge or measuring stick 29 which is inserted through the aperture in the plate or inner cap 26 and is of length sufficient to extend from the bottom of the tank to a point slightly above the inner closure member or cap 26; the measuring stick 29 (which m'ay be of comparatively thin sheet metal) being provided with suitable graduations commensurate with the capacity of the tank, whereby to indicate the number of gallons of oil, or other suitable liquid within the tank. ln order to determinefthe quantity in the t'ank, it is, of course, necessary to withdraw the gauge 29 so as 5to .determine the heightyof the liquid andits stagefrelative to the graduations.
The inner closure member or cap 26 is also provided with a lshort pipe or tube 30 which may be screwed into a tapped opening in the cap 26, while the upper end is preferably threaded to receive 'a screw-cap as at 31; the tube 30 constituting a filling tube for the tank through which the oil is introduced. The inner cap or plate 26 is provided with a third aperture to receive a suitable hand pump 32 adapted to take the oil from the bottom of the tank; as the pump, which is rovided with 'a threaded nipple to receive a ioseconneetion, is of the usual well knownv construction, detailed description thereof need not be here entered into. The three apertures in the inner closure member or of the bottom and the top of the main portion of the tank; vwhile the inner shell or lining 35 of the neck 1l of the tank is also preferably circumferentially corrugated, thereby providing what may be termed a self-supporting form for the concrete eX- terior while at the same time reenforcing the tank throughout its height. The corrugations of both portions of the inner shell or lining are preferably outwardly disposed so as to permit them to become embedded in the hydraulically setting or cementitious material as cle'arly shown in `l3`igure 2. As the other features of the tank are identical with these shown in Figures l and 3 and as previously described, further description of such features or portions need not again be entered into.
lnboth constructions, the cap or plate 26, at diametrically opposite points, is provided with notches for the passage of lugs 27, 27 formed on or secured to the inner lining 'i6 or 35, as the case'may be, so that a partial rotation of the cap or plate after passing below the lugs, will prevent accidental lifting of said cap or plate 26, thus n'iaintaining the latter in place; while removal of the plate 26 .may readily be accomplished when the notches are brought to register with the lugs 27, 27.
The constructions disclose an integral unit or inner cap for securing the gauge, pump and filling tube and maintaining the same in the neck of the tank in'easy accessible position; at the same time enabling all of said elements to be removed 0r withdrawn from the tank upon the removal of the inner plate or cap 26.
l have described what I believe to be the simplest forms of my invention in terms employed merely for description 'and not employed as terms of limitation, as structural modifications are possible and may be made without, however, departing from thc spirit of-my invention.
