STORAGE TANK Filed Jan. 18, 1928 3 Sheets-Sheet 5 Patented May 27, 1939 This invention pertains to the general class of receptacles and particularly to a storage tank. An object of applicants invention is the production of a tank capable of complete- 5 ly discharging its contents. A furtl er object of applicants invention is the production of a novel gate construction for opening and closing the discharge opening of said tank. A further object of applicants invention is the production of a tank simple to erect, of low cost, easy to manufacture, durable and satisfactory for its intended purpose. other objects and advantages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

The tank disclosed in the drawings is intended as a storage ta cause a great deal of abrasion and corrosion. This applies particularly to ash, high sul phur coal, coke, coke breeze and the like. Applicants tank is constructed of a frame work of steel to which are attached a plurality of overlapping plates. readily knocked down and transported from place to place, easily erected and replacement of plates is readily effected. ine material used in constructing the plates is preferably cast iron. However, it is obvious that other as suitable materials may be used.

is so constructed that the material of the plates only comes in contact with the contents of the tank. The steel structure is employed to hold the Jlates in place.

To this end my invention consists in the novel construction, arrangemei'lt and combination of parts herein shown and described and more particularly pointed out in the claim.

In the drawings, wherein like reference characters lndicate like or corresponding parts Fig. 1 is a front elevation of applicants novel tank;

ing upright corner posts 2, 3, 4 and 5. Uprights 2 and 5 support a beam 6 at the tops thereof. Uprights 3 and l support a beam 7 at the tops thereof. Suitable bracing may be employed as desired. Beams 6 and 7 support cross beams 8 and 8. The tank proper is made up of a plurality of upright plate supporting members 9 which are preferably of structural steel such as I-beams. bottom of the tank the plate supporting members converge as shown at 10, thus forming a discharge opening 11 at the bottom of the tank. As previously set forth, the members 9 and 10 may be of any standard structural shape, but are preferably limited to ashape having a transverse web such as a T-shape or I-shape. The plate supporting members of the roof shown at 12 in Fig. 2 are preferably T-shaped. Any conventional means may be employed for attaching the members 9 and 10 to the framework as well as for connecting the members 9 and 10 to each other and the members 9 and 1.2 to each other. 13 of the tank are preferably of angle iron having webs forming an angle of with v The form of tank shown in the drawing is merely for the purpose of illustrating applicants invention. it

pivot point of each gate. It is thus readily seen that either of

gates

18, 19 and 20 may be opened individually or any or all of the gates may be opened as desired. When all of the gates are open, it is readily seen that the discharge opening 11 at the bottom of the tank has nothing therein to obstruct the dis charge of the contents of the tank. This particular gate construction is highly efilective for its intended purpose. The entire bottom oi the tank may be opened, said opening be ing entirely unobstructed, thus preventing arching and sticking of the material and a complete discharge of the entire contents of the tank is assured. Each gate is operated by means of its lever 23. A chain, rod, cable or other device may be attached to the outer end of lever if desired. Beams 41 and 42 supp 'ted by brackets on beams 14 and 15 assist in supporting the plate supporting members 10 at the opening 11.

In Figs. 1 and 2 the tank is shown with a vent l0. he bottom edges of the vent 40 are rabbeted similar to a plate. Vent 40 is merely substituted in place of the plate on the roof. It is readily seen that a plate anywhere in the structure may be removed and any sort of device such as a cast iron manhole may be substituted in place thereof, same fitting in as part of the structure.

The bottom of the tank may be wedge shape as shown in the drawing or same may be of The steel frame work adds strength to the structure. However, no steel comes in contact with the contents of the tank. The sloping bottom gives maximum discharge capacity. The gates extend the full length of the tank which insures positive discharge by gravity. The gates may be of any number as will be appreciated by persons skilled in the art.

The tank may also be constructed With a bottom sloping at an angle completely across the tank, and thedischarge opening and the gates for same in this case would be at a bot tom side edge of the tank.

Having thus described my invention, it is obvious that various immaterial modifications may be made in the same Without departing from the spirit of my invention; hence 1 do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.

hat I claim as new and desire to secure by Letters Patent is:

In a receptacle of the kind described, a pair of opposite side walls converging to form a bottom, said converging side walls terminating to form a discha' opening, a plurality of laterally arranged ates for said discharge opening, said gates individually operable and having adjacent margins over lapping, said gates supported by means tree of said discharge opening whereby when all of said gates are open the flow from said discharge opening is unobstructed.

In testimony whereof, I have hereunto signed my name.
