I application filed December To all whom it may concern."

. Beit known that I, An'rrrtm P. STRONG, a citizen of theUnited States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Ash Tanks, of which the following is a specification. This invention relates to metal hoppers and tanks for the collectionand disposal of ashand other disintegrated materials.

Storage .tanks of the type having their walls made of removably mount-ed sectional plates are not adaptable, as thus-made, for use in systemswherein the'ash or othermaterial is moved through the pipelines by suction on the tanks because the joints between the plates are not sealed against the passage ofiair into the tank.

One object of my inventionis to provide means in connection with tanks of this gen eral type whereby they are rendered substantially air tight and thus adaptable to use in pneumatic systems of the kind mentioned. V Another object of my invention is toaccomplish this purpose by providing thetank V with an outside imperforate wall, thusmaking the tank of a double wall structure.

A further object of my invention is to employ the imperforate wall as ameans for preventing the tank structure from swaying during the building of the sectional in-- side wall, and thus avoid the use of cross ties as heretofore.

The invention consists furtherin the matters hereinafter described and more particularly set forth in the appended claims.

' In the accompanyingdrawings-g Fig. l isa side elevational view of a storage tank or hopper constructed in accord ance with my invention; Y

F ig. 2 is an enlarged vertical sectional view taken through the tank; and

Fig. 3 is a horizontal sectional view through one of the upright corners of the tank, taken on line 33-of Fig. 2,. V

In the drawings, I. have shown a storage tank or hopper of the type having upright side and end walls and a hopper bottom providedwith a gate controlled discharge opening, as customary in structures of this general kind.- The tankor hopper is usually elevated or supported above the ground or platform, as the case maybe, at the dis tancerequired to permit emptying of the TANK.

'As shown in Fig. 1, the structure includes a plurality of u right supporting ' posts 1, 1 at the four corners of :the tank. and extending upward the samev distance. 7 These posts support at their upper ends .ahorizontal base frame 2, from which rise a pluor truck when moved'underfl': I

ralityof upright I- beams 3, 3 laterally a spaced apart and forminga portion' of the upright side and end walls of the'tank.

Extending between and secured tosaid' I- beams 3, 3 are cross-members 4, .4;horijzontally arranged and spaced apartvertically;

The cross-membersfS, 3'are of-channel shape to accommodate the hooksj5 of-plate supporting bars or members 6'. 'These bars 6X? tend downward and are channeled along their side edges to receive and support the plates 7 7 which form the inner wall of the tank. This construction is' substantially like that disclosed in Patent N 1,243,873, granted October 23, 1917, to; H. A. Poppenhusen and myself, and needs'no further description herein, except to remark that the plates? 7 in the various vertical rows over-F lap each other along their upper and lower, edges, respectively, on the inside=of the wall and have a sliding connection withthe members 6 so that the inner 'wallf o'f the tank may. be built up and, further, bereadily taken apartfor repair. p

To adapt such type of tank orhopper to a suction type of system, that is, a system" wherein, the ash, or other material being I v a suction on the tank, I havecncased the sectional wall of the tankinan imperforate casing so as to make the tank substantially air tight to hold a suction. This casing is arranged outsideof the sectional inner wall: and comprises a pluralityof plates 8, 8 for the upright .wall of the tank and similar plates 9, 9 for the hopper bottom. .In the upright wall of the tank, the plates 8, 8;; are arrangedin horizontal and vertical rows and havctheir side 'edges'rivetedor l I otherwise rigidly v secured to the upright members or I- bean1s 3, 3"on the outs de thereof, as ShOWILlnlthQ drawings.- The uppermost- plates 8,8 have their upper edges riveted or otherwise; secured to the frame 7 member lllextending about the top of the tankand from which the uppermost plates 7 of the inner walls are suspended, as shown of the system, and at one side of the centeris a pipe 1 whereby the required suction maybe placed on the tank for-conveying the material from the pipe line into the tank, as

"customary in -ash conveying and like -s'ys terns of suction type. V Y

The lowermostplates 8, 8 oi"? theupright marginal wall of the tank have their'lower edges riveted or otherwise secured to a channel member 15 on top ofthe I-beams'of the base frame 2 and" from this-member rise the uprights'fi, as shown in' Fig. 2. The uppermost plates 7 7 forming .the inside of the hopper bottom are suspended from me1n here 16 associated with this channel meniher'15.

The uppermost outside plates 9 of the hopper bottom are flanged outward,- as it 17, and are secured to the under side of the Lbeams (a? the base member 2-, as shown in Fig. 2Q The base member 2thus5closes the space between the lowermost outside plates 8, 8 of theupright tank wall and the uppermost outside plates 9, 9 of the hopper bottom, with the result that no air can leak into the-tank around the'base member 2 to impair the suction on the tank.

The gate structure at the bottom of the hopper includes a gate casting 1S surrounding the outlet opening in the bottom of the hoppcnand this casting has an autwardly extending flange 1'9surrounding, the same. The lower ma'rginsof the lowermost outside plates 9 of the, hopper bottom are flanged, as at 20, and are suitably secured by rivets or otherwise to the flange 19, as shown in Fig. 2.. This providesan air seal at this point. P p

The construction at each of the four corners of the hopper is as shown .in Fig. 3.

As there illustrated, the innerwall of the hopper is formed of vertically arranged sectional plates 21, shaped to form a corner and supported by the hook carrying memhere 6 at the side edges of such plates. The

outside wall or casingat the corner includes the plate 8 at such corner and one plate has a flanged side edge, as at 22, to overlap the edge of the adjacent late 8 and is riveted or otherwise secured thereto. As shown in Fig. 2, the outside plates 8 in the'upright walls overlap each other, as at 23, between the uprights 3, to form an air seal between such edges of such plates; while the outside plates 9 in the hopper bottom overlap. as at 24:, between the inclined end members of the supporting structure of the hopper bottom, to make an air seal at suchpoints.

By the construction described, the tank make walls are made double, that is, there is an inner wall against which contacts the material. discharged into the hopper and an outer wall, the latter being so, made as to the tanks substantially ltight and thus adapt itself to those types of systems which progress the material through the pipe line by a suction on the tank' The plates otthe t-wo'walls are spaced apart by, the interposed framework of the tank structure and supported by that-"framework. 7 @ne of the walls'otl" the tankis-formedo't removable plates so that such'wall may be repaired when desired and, furthermore,

permit the building up of that wall" as the tank is installed; The outside walls being formed of rigid plates rigidly connected with the framework of the tank structure makes the entire unit supported by .the four posts 1, 1, and thus allows build ing up of the innciiwall withoutthe uscoftie'rods for the upright wall ofthe tank. This outside wall being a supporting unit,

prevents the tank fromswaying and avoids the use of tie rods for that purpose as hereg tofore'made necessary. The inside plates 7,
