HUDSON, OF BUTLER, PENNSYLVANIA, ASSIGNOR TO THE AMERICAN ROLL- ING MILL COMPANY, OF MIDDLETOVVN, OHIO, A CORPORATION OF OHIO PICKLING- TANK CONSTRUCTION Application filed September 18, 1928, Serial No.1306, 638.

It is an object of my invention to provide a type of tank which may be constructed in place at a minimum of expense.

It is a further object of my invention to facilitate the use of cheaper materials in pickling tanks, and particularly re-inforced concrete. I 7

Since some leakage and ill repair after protracted periods ofuse is unavoidable, still further objects of 'my invention. are provision of means for detecting. leaks and locating them within a reasonably small area, the

I conducting away of the leaking acid, and the protection of the concrete therefrom.

Still a further object of my invention is the provision of a novel tank construction employing hollow tiles, whereby the above objects, and others which will be apparent to one skilled in; the art upon reading these specifications, will be subserved.

I attain theseobjects by that certain construction and arrangement of parts of which I shall. now describe a preferred embodiment, reference being made to the drawings which form a part of these specifications.v

In these drawings v I Figure 1 is a view, partly pickling tank of my construction.-

. Figure 2 is a tile prepared for. use onthe floor of 1ny,tank.,,

I prepare a re-inforced concrete construcr as tion resting upon feet 1 andiZ. Extending therebetween is a sub-floor 3 with a 'sl anting upper surface. A" heavy upright-wall 1 .rests upon the foot '1 and furnishessupportj forpne side of the tankfj The tank proper piece.

a fl or ofconcrete fand1side-walls hand 1. The other side of the tank proper is supported upon the sub-floor by interspaced piers 8. All of this construction is prefer- ..a re-mi'orcec con e e nave s o n blyof crt I he rod re nforcements at 9) 'and cast in one t s one ofthe advantages of my construction that it permits the use of concrete in this fashlon; but other naterials may be used and will fall within the scope of my invention. p

The concrete fioor'5 of my tank, is of standard reinforced concrete and tile construction excepting thatthe tiles 10 are set in on end with the cells in a'vertical position. These tiles are preferably spaced at 12 centers along the longtiudinal axis of the tank.' The concrete between the tiles forms girders 11, properly reinforced with steel rods to carry tension loads. Theseconcrete girders are poured to a height of 1 inch below the top ofthe vertical tiles'l'eaving a space overlying the girders. This space I fill level with a layer of asphalt mastic cement, which I have indicated at 12. Thus the floor of my tank comprises a concrete platform 5 pierced transversely by lines of acid proof hollow tile, the cells of which form conduits leading throughthe floor, and opening above the subfioor 3. And the girders demarked by. these tiles are top-sealed with a coating of asphalt; 'cement. The v girders are thus protected from acid on top by the mastic and on the sides by the tiles. The tiles, as will hereinafter'be more fully explained, act as weep holes for any acid which may leak through the first lining. V

The concrete side walls, 6, are an integral part of the floor in my preferred construcin sectionand V partly in perspective, of a portion of an acid p p hydrostatic head in the tank. Both walls tion, and may, be designed as a cantilever beam to resist the overturnmg moment of the and fioorofthe tank are broken at intervals to provide expansion joints which are necessary inrvery long tanks. I haveshown one of these ointsin the floor, and comprising a suitable. I find it satisfactory to provide an I I tions; but its action is not, perfect.

expansion joint every twenty feet, more or less.

I coat the side walls with a layer 16 of asphalt mastic, making this continuous with the mastic layer surmounting the floor girders. My tank is now ready for the application of the inner layers.

The floor of my tank I next lay with a course of hollow tiles 10a with the cell spaces following-the longitudinal axis of the tank. These tiles will be laid so that their meeting edges lie over the cell openings of the vertical tiles in the floor. Twelve inch tiles will serve for the floor providing the transverse courses of vertical tiles have been laid on twelve-inch centers, The tiles 10a will have notches 10b chipped from their lower edges to permit any liquid which comes into the cells to drain therefrom into the cell openings of the vertical tiles. The corners of my tank I preferably finish with angle tile 100. The cell partiti'ons of these tiles are chipped away as at 10d to permit flow between and into the cells. There will be no notches in the bases of these tiles if the transverse rows of vertical tiles stop. short of. the sides of the tank. Surn ounting the angle tiles and covering the wall- 6 is a course of tiles 10c laid with the cells vertical. WVhen the entire tank'is thus lined with tiles,I coat it within with another asphalt mastic seal 17, and it is then ready to receive the acid-proof final lining.

The layer of acid proof hollow tiles, 10a,

etc. serves a number of purposes. It acts as insulation for the tank, which is of some mportance in the use of hot pickle liquors. It makes possible the use of two mastic seals, which is a matter of great importance The construction of a successful pickle tank involves the coordination of a number of factors. The inner acid-proof lining with its mastic seal, however well protected by expansion joints and the like, isv subject to cracking and leakage. A mastic seal is intended to protect the nQn-acid-proof tank proper from corrosion under these condi- In my .-.onstruction, I provide the tank proper with a second mastic seal s parat d from the first by an open-work structure so that initself it is less. subject to-the immediate influences tending to crack the acid-proof-lining.

leak can be determined within a small space by observing the drip. This subfloor, I prefer to provide with an acid-proof lining 17' similar to that next to be described for the tank, and to line the interior portion of the upright 4L therewith also, as at 17a. The piers 8 are made of, or lined with'acid-proof material. The slantwise disposition of the top of the sub-floor causes seepage to drain into a gutter 18 by means of which it is conducted away. 7 I

A number of acid proof substances or constructions will serve for the acid proof lining 17b of the interior of the tank, and the

linings

17 and 17a of the sub-floor and wall. The one I prefer to use comprises a course of acid-proof brick laid in acid-proof cement. A satisfactory cement is a heat'plastic comprising sulphur and sand; but others are suitable. At intervals along the interior lining I provide for expansion joints which preferably coincide'wit-h the expansion joints of the tank proper. A convenient form is a wooden strip. 19 embedded as shown in a space left in the lining. These joint-s not only allow for expansion and contraction,

but when constructed as shown, further minimize cracking by causing the composite tank to act as a unitary construction.

The tank Walls may be surmounted, as shown, by granite slabs 20'.

Modifications in my construction for different types of tanks will suggest themselves to one skilled in the art, as will substitution of materials.

Such changes, however, are included within the scope of my invention of which I have described a preferred embodiment; and what I claim as new and desire to secure by Letters Patent, is:
