ASH HOPPER.

Application led October 6,1921. Serial No. 505,702.

`To all 'whom 'it may concern Be it known that l, ARTHUR P. S'rRoNGa at Chicago, in the county of Cook and tate of illinois, have invented new and useful improvements in Ash Hoppers, of which the following is a specification.

This invention relates to metal hoppersor tanks for the collection and disposal of ash or other disintegrated materials.

@ne object of my invention is to make the walls of the tank or hopper of supporting beams and metal plates and to secure the plates to the beams by bolts as distinguished from' hooking the 'plates over the beams or having their side edges engaged in channels in the beams.

A further object is to provide means for covering and protecting the .inner ends of Vthe bolts from corrosion or abrasion from packed orstoredin the tank the material or hopper;

rihe invention consists further in the matters hereinafter described and more particularly set forth in the appended claims.

ln the accompanying drawings- Fig. 1 isa side elevational view of a storage tank or hopper constructed in accordance with my invention;

F ig. 2 is an enlarged fragmentary inside view of a portion of one of the upright walls of said tank or hopper; i

AFig. 3 is a vertical 'sectional view taken on line 3-3'of Fig. 2;

Fig. i is a horizontal sectional view taken on lined-4 of Fig. 2;

Fig. 5 is an elevational view with section of the structure shown -in and 1 Fig. t is a wall plates.

lin the drawings, l have shown a storage perspective'view of one of the I tank or hopper of the type having upright vside and end walls 1, 1 and a hopper bottom 2 provided with a gate controlled discharge opening, as customary in structures of this general kind. The tank or hopper is usually velevated or supported above the ground or l A platform, as the case may be, the distance required to permit emptying of the hopper into a car or truck when moved under the same. Asshown in Fig. 1, the structure includes a pluralitvfp upri ht posts 3, 3 for this purpose. "The uprig t side and end walls 1, 1 rest on and are connected with a .Said beams 5 extend upward the same distance and are all connected together at their upper ends by a cross-member 6 at the top of the tank or hopper, as shown in Figi.

The spaces between the upright beams 5,

5 are closed by metal plates 7, '7. rlhese 'are arranged one above the other in each of the vertical spaces and are located' inside of the beams, as-shown.v The plates 7 are secured to the beams between which they extend by bolts 8 ,8, these being at the upper edge of each plateonly, in the form of structure shown in the drawings. rlhe bolts 8 extend through the plates and side flanges of the beams overlapped by the plates, and have their heads 9 inside of thev plates, while their threaded outer ends extend` outside of the beams and in position 'to have the clamp nuts applied thereon. Asshown in Fig. 3, the' upper edge or margin of one plate 7 is overlapped on the inside by the lower margin of the plate thereabove. This closes the joints between such margins of the plates and prevents the material lpacked in the tank from leaking out between the plates. By having the overlapping inside, a downward, shed is provided and avoids upwardly facing ledges for the material to accumulate or collect on. The side edgs of the plates 7 either abut or are closely adjacent the like edges of the associated plates on opposite sides thereof and these edges overlap 4the associated beams 5, 5 to prevent leakage between the beams and the plates.

Each plate, as shown in Fig- 5, is provided along one of its side edges with an integral, inwardly offset portion or flange 10 1n a plane parallelto the plane of the plate body.4 The flange 10, as shown in Fig. 5,- has its upper end short of the upper edge of the plate, while its lower end extends to the bottom edge of the plate and continues around the corner thereof to provide a recess or pocket 11. rlhe flange 10 overlaps the side margin of the adjacent' Side plate 7 and closes the joint between the plates to 7 immediately below said flange 10, and the bolt 8 which secures to said beam 5 the upper right-hand corner of the plate 7 to the right of the plate with which the righthand bolt is engaged. The `lange 10 is provided with an inwardly extending hori- Zontal rib 12 to close the pocket 11 from below and prevent the material finding its way into and filling the pocket 11. The opposite lower corner of the plate 7 is cut out, as at 13 and 14. The former is larger to clear the lefthand bolt head 9, shown in Fig.l 5, and its edge 15 closes the adjacentside of the pocket 11, and the notch 14 seats on the rib 12, as shown in Fig. 5. Thus, the pocket is closed from the side as well as the bottom, and on the opposite side of the integral portion between the plate body and the flangelO. 'lhe upper end of the flange 10, terminating short o the upper edge of the plate, accommodates the lower end of the flange 1() on the plate thereabove, as shown in Fig. 3.

All ofthe bolt heads 9 in the wall structure are located in pockets 11 and thus are shielded and protected from corrosion or abrasion from the material stored or packed in the hopper or tank. 'lhi's is,a marked advantage, because the life of the bolts is prolonged by being free from abrasion as the tank is filled and emptied, and, shielded from corrosion. may be readily removed and replaced in making repairs to the tank. Moreover, these features make ossiblc the use of bolts for securing the p ates to the supporting beams as ythe objection to corrosion and abrasion is'overcome.

The hopper bottom 2 of the tank may be constructed like the upright Walls, or in a manner similar to that shown in either of the prior Patents Nos. 1,243,873, granted Oc# tober 23, 1917, or 1,311,296, granted July 29,

V1919 tomyself and Herman A. Poppenhusen. While I have shown and described herein 1n detail a hopper or tank constructed in ac- .cordance'with my invention, it is o f course to be understood that the details of construction and arrangement of parts may be variously changedfand modified without departng from the spirit and scope of my invenion.

I claim as my invention:

1. A wall, comprising plate supporting beams, plates arranged inslde of said beams and Yclosing the spaces between the same, and

bolts securing the plates to saidbeams, said i plates having means extending over the inner ends of said bolts for protecting the same from contact with 'the materlal packed against the inside of said wall.

2. A wall, comprising plate supporting beams, plates arranged inside of sald beams and closing the spaces between the same, and bolts securing the plates to said beams, the bolts of one plate having their inner ends overlapped and coveredby the marginal portion of another plate for protecting the 'bolts from contact with the material packed against the insidei of said wall.

3. A wall, comprising plate supporting beams, plates extending across the spaces between said beams on the inside thereof, and bolts securing the plates to said beams,

each plate having an inwardly offset man' ginal portion overlapping the adjacent plate and extending over the bolts of the latter plate for protecting the inner ends of the same from contact with the material packed against the inside of said wall.

4. A wall, comprising plate supporting beams, plates extendin across the spaces between said beams on t e inside thereof, and bolts securing the plates to said beams, each plate having an inwardly odset marginal portion extending around one of the cor ners of said plate and overlapping the two adjacent plates for covering the bolts of the latter plates and protecting the same from contact with. the material rpacked against the inside of said Wall.

5. An upright wall, comprising plate supporting beams, a plurality of plates extendmg across the spaces between said beams on the inside thereof and arranged in horizontal and vertical rows, bolts securing the upper end of each plate to the beams, each plate having an inwardly offset marginal portion on one side and extending around one of the lower corners of the plate, said offset portion overlapping the side of the adjacent plate and the adjacent upper corners of the plates immediatel therebelow and covering the bolts of said plates;

6. A wall, comprlsing a'base member, upright beams secured to and supported by said base member, said beams being laterally c t: r. saone'.
