To all whom it may concern:

Be it known that I, HowARo G. HARRISON, a citizen of the United States, residing at Spokane, inthe county of Spokane and State 0 strong wall sections, yet that may be made of reasonabl light material which will readily sustaln itself and the load it is to carry without sagging or lopping especially tank.

during transportation from one location to another.

A still further object is to provide a grain bin or tank mounted upon sln'ds and resting upon a floor supportedby said skids and being capable of being dragged from one field to another or to any other'desiredlocation.

- 'Another object is to provide improved means for alleviating the bursting strain caused by the pressure of the contents of the bins against its walls.

7 My invention is illustrated in the accompanying drawings, in which Figure 1 is a lan view of my bin or tank.

I Fig. 2'is-an e ovation thereof showing the tank mounted up'on skids.

Fig.3 is a detail in cross section through the ventilating .cupola of my tank. FFig. 4 is a cross section through 4-4 of ig. 1.

Fig. 5 is a perspective of one of the sectional roofplate's.

Fig. 6 is a partial'perspective view of one of the roof rafters- Fig. 7 is a partial section through the tank at 77 of Fi 2 showing the interior hopper alined to de 'verinto the The tank shown in the drawings is more particularly of the t e used for storing grain, although I do not limit myseltto the use of my construction to tanks for this purpose only but may use it as well for seed storage, S1108, etc.

The wall of the bin is made up of a numspout of theber of circular corrugated sections placed one above the other but with their joints in staggered relation, each circular section being composed of a number of units comprising a main corrugated plate 1 provided with bolt or rivet holes 2 along all edges inspaced relation and so positioned to accurately engage with any adjoining plates, either on the ends or the sides thereof. The

-units comprising the bottom circular section 3, are riveted t0 the perpendicular leg of clrcular angle irons 4, said irons taking a position on the inside of the circular sections 3 and the horizontal leg bein formed to extend outwardly and same ing provided with holes by which the tank may be secured to floor 5. Several of the unit sections 1 are provided with a spout 6 closed by a valve member 7 through which grain may be taken from the tank in quantities as desired. The spout 6 being attached to certain unit sections may be placed at any desired eleva- "tion in the tank to load grain directly into a wagon or to be used as a spout for filling sacks and the like. The unit sections 1 may be continued to any desired height to in crease the capacity of the tank and the roof members are attached to provide a substantially moisture-proof container or tank for the contents thereof. As an improved means for alleviating the bursting strain caused by the contents of the tank against these walls and of the strain-upon the rivets or bolts by which the tank is fastened together, I provide circular hoop members 8 consistin of semi-circular formed rods 1 provided with a hook 9 on one end and two of these rods engaging with a: link -10 to form a secure'fastening but which may be readily detached for transportation.

Upon opposite ends at 11 the rods 8 are threaded and engage with the tensioning member 12 which provides means for. overlapping the rods and consists of two barrel shaped members through which the rod ends may fipass and a nut attached to tighten the rod rmly around the tank. The corrugations-of the unit members provide a means --for holding the rods in circular relation and preventing them from dropping or saggin Upon the inside of the tank located to fit into the spout 6, is a hopper 13, thus attached by rivets or bolts 14 and is arranged to de-' liver any Very often it is desired to have the spout' at an elevation above the bottom of the tank in order to pour the contents of the tank into I a wagon body, in some cases it is necessary then to have the spout a section or two above the floor or bottom of the tank and to allow gravity to take care of all of the grain above the top of the hopper 13, the balance of which is necessary to shovel or mechanically elevate when it will flow by gravity into the receptacle for it.

In order to provide an easy means for conveying the tank from one location to another, I provide a floor structure of which 5 is the floor, 15 floor sills for supporting same, 16 spacing posts and 17 skids or runners. I prefer to shoe these skids with band iron 18 to eliminate undue friction when transporting the tank. A link 19 attached at 20 serves as a means for attaching a team by which the tank may be dragged. The posts 16 may be of any desired length properly placed to thoroughly support the tank and their length is usually ad usted to give the proper height or elevation of the tank so that the contents may be loaded into wagons or other receptacles as much as possible by gravity.

The roof of the tank is constructed of a number of segmental circular units 21 having upturned edges 22 lying at an acute angle into the top surface of the unit. In assembling the roof these units are placed together so as to form a conical shaped roof, the oints being formed by placing the rafter member 23 at intervals corresponding with the width of the segmental unit and attaching it to the side circular sections 1 at the to thereof,engaging the other end of the ra er member 23 to the cupola structure hereinafter to be described. The rafter 23 is formed in a substantially inverted U-shaped structure 24 with outstanding flanges 25 and serves a double purpose of supporting the weight of the segmental sections 21 and of any load that may be placed upon it, and also serves to suport on its inner end a cupola structure 26. he inner end of the rafter 23 is provided wlth tongue members 27 extending beyond the general limit of the rafter and provided to engage with the aforesaid cupola structure to support same. Upon the opposite end of 23 1s a downwardly depending angle plate 28 riveted to 23 and provided with su1table holes for attachment to the corrugated circular sections 1 upon the upper edge thereof. The cupola structure 26 consists of a circular collar 29 with a conical flange 30. At 31 which is the base of 29 are provided slits for the reception of the tongues 27 which may be entered and turned upward to positively engage 29 and secure same to the rafters 23. In addition to the above, a second fastening 32 is mounted in the end of 23 and consists of a filler block which is provided to support pins 33 which engage in holes 34 in the flange to actively support the cupola in its proper position without causing undue pressure upon same The cupola structure 26 is provided with a conical cap 35 which is supported somewhat above the rest of the structure to allow for ventilation for the tank. 35 is provided with a plurality of leg members 36 engaging in sockets 37 to substantially retain 35 in spaced relation with the collar 29. Surrounding the collar 29 is a flange member 38 slidable upon 29 and provided to be adjusted over the inner ends of the rafters when the roof is completely erected and serves the useful purpose of preventing rain from entering the tank, past the ends of the rafters and the segmental section 21. The segmental section 21 is provided with an upturned end 39 which will prevent rain being blown over the end of the section and thence into the tank. An inverted U-shaped seal 40 is provided to engage the segmental sections 21 in engagement with the rafter 23 and provides a seal to make the roof structure water-tight at the joining of the several sections.

After the rafters have been.mounted the segmental sections are usually inserted and rest upon the outturned flanges 25 of the rafter. The sealing member 40 is then slipped over the end of the rafter and segmental sections and over the entire length of same until it provides a secure fastening and weather tight joint extending from the cupola to the eaves of the roof.

In filling the tank the conical cover' on the vcupolamay be removed and the tank filled directly from' a separator of a threshing machine delivery spout. In practice, however, it has been found very convenient to remove one or more of the roof sections and pour the formed. When it is necessary to enter the tank a roof section may be removed which will make access convenient.

While I have herein shown and described limit myself thereto, but expect to use it grain through the opening thus in any form to which it may be applicable.

I claim 1. A cone shaped, circular roof structure composed of radial, longitudinally tapered or segmental sections formed with upturned side flanges, means for uniting said sections, said means consisting of rafter members disposed radially between adjacent sections, "each member bein' composed of an upstanding, channelli e, longitudinal rib having outstanding side flanges, and a longitudinal, channel-like sleeve member embracing said rib and the adjacent upturned flangesof the adjacent sections.

2. A cone shaped, circular roof structure consisting of a centrally disposed tubulai' a depending, coniring member supportin cal or flared flange, sai ring member being provided with a series of slots and said flange with a series of apertures; radial, longitudinally tapered or segmental sections formed with upturned side flanges, means for uniting said sections, said means consisting of rafter members disposed radially between adjacent sections, each member being composed of 'an upstanding, channellike, longitudinal rib having outstanding side flanges, and a longitudinal, channel-like sleeve member embracing said rib and the adjacent upturned flanges of the adjacent sect-ions, said rafter members being further provided with extended tongues at their inner ends passing through the slots of said V tubular ring member and with downwardly directed members engaging said apertures of said conical flange.

In testimony whereof I afiix m signature.
