To all-whom it may concern: I

Be it known that I, WILLIAM JOHNSTON, of the city of Winnipeg, in the Province of Manitoba, Canada, have invented certain new and useful Improvements in Grain- Tanks, of which the following the specification. I

My invention relates to grain tanks and the object of the invention is to provide a portable, simply constructed, fireproof tank having convenient inlet and outlet openings therein whereby properly placed in the tank "and quickly withdrawn when required, such tank being further waterproof, strong and durable.

' It consists essentially in thenovel arrangereferred to and more particularly pointed out in the appended claims.

Figure 1 is a side view of my tank closed. Fig. 2 is a plan view of the same. Fig. 3 is an enlarged detailed horizontal. sectional view through the side thereof, the section being taken in the plane denoted by the line X X, Fig. 1. Fig. 4 is an enlarged detailed chute and adjoining parts looking at it from the interior of the tank. Fig. 5 is an enlarged detailed vertical'sectional View through the outlet chute showing it open. Fig. 6 is an enlarged sectional view through a portion of the roof-.of the tank, the section being taken in the plane denoted by the line Y Y, Fig. 2. Fig. 7 is a front elevation of the tank frame work showing particularly the roof construction.

In the drawings likecharacters of reference indicate corresponding parts in each figure. v

1 represents the base of the tank which 1s octagonal in plan and is covered over in any suitable way by a metallic covering in order 'to render it proof of fire. The base 1s supported on suitable cross beams, or 1f desired, can be mounted on rollers so that the tank can be drawn from place to place when desired. To the upper face of the base I have secured beams 2 which are arranged in the form of a circle and areutilized for holding the-sides of the tank as shortly des ribed.

3 are upwardly directed beams secured at the lower ends firmly to the beams 2' and spaced at suitable intervals, such beams being united at their upperends to a doublethickness of horizontally disposed beams4.' Cross beams 5 are secured attheir ends to the beams}; and diametrically across Specification ofLetters Patent. Application filed June 29, 1010. Serial No.

the tank, bein'gsuitably connected centrally. A post 6 is supported centrally by the beams 5 and passes upwardly to form the peak of the roof.' Roof beams 7 radiate from the top of the post 6 and are secured at their outer ends to the beams 4. Suitable braces 8 and 9 pass between the beams 7 and are arranged concentric to the post 6.

The parts just described form what I term the frame of the tank.

10 is the body of the tank which is formed from corrugated metallic sections 11, the corrugations. running vertically. In the completed tank the edges of the adjoining section are interlocked and are secured to the upright beams 3 by nails or screws. The lower ends of the sections are fitted against the outer sides of the beams 2 to which they are secured, while the upper ends are nailed or screwed to the beams 4.

12 is the tank roof formed from similar triangular shaped metallic sections 13 having their edges interlocked at 14 so as to form a water tight joint. The sections'are secured to the beams 7 and braces -8 and 9, and the customary opening left at the peak of the roof forven'tilating purposes is covered over by a cap piece 15 carrying a cone shaped top 16. One of the sections 13 is cut away to provide an opening at 17 in the roof through which the. grain is inserted in the tank. The edges at the sides of the opening are turned upwardly at 13 and two similar plates 18 are secured by nails to the opposing faces of the adjoining beams 7 and have their upper edges turned over the, upwardly turned "edges 13 of the section 13.

It will be understood have been purposely located more or less centrally beneath one of thesections 13, so as to support the section-in which the open ing 17 is formed. The plates 18 hold the edges 13 of the section to the beams and the construction does not expose the nail heads to the weather.

The opening 17 is closed by acover 19 which has its ed ges turned upwardly and backwardly at 20 so as'tofit over the upper edges of the plates 18. When the cover placed on the roof of the tank the up er end slips beneath a hood 2l securedtot e section, which hoodpr'eventsany water from passing into the tankbetween-the-upper end of the cover and the roof. The lower end I secured to the tank by any suitable form of hook and eyeilocated at 22.

that two beams 7' Y If desired this could be fastened by a pad- ,lock rather than the hook.

3 close against the bee.

One oi the corrugated sections 11 is par tially removed to provide a door way opening at 23, which opening is closed by double. doors as now described. An outer door '24 itormed from a metallic plate is hingedly secured to one of the beams or uprights 3 and has the opposite side fitted with a hasp 25 fitting'over a staple 26 passing into another of the beams 3. A padlock can be employed for locking the door.

' -27-'and 28 are two, vertically directed beams firmly secured to the beams 3 immediately behind the door, which beams in combinatiomwith an upper and'a'lower cross beam 29 form the door frame.

; Q30 is an inner door formed from an upper section 31 and a lower section 32, which sec- 'tions are hinged at 33 to the 28 and s 27.. The edges of the inner door are rabbeted so as to form a grain tight joint the beams 2'? and 28.

3d and 35 are upper and lower straps passing completely around the body of the tank at the top and bottom, and 36 and 37 are further straps passing centrally-around it for reinforcing purposes. The straps 36 and 37 have portions thereof 38 and 39, respectively, removable, such portions passing across the outer door 24. In order to remove them it is only necessary to undo the nuts on the bolts 40 which pass through the outwardly turned ends ll of the connected parts. 3 ,4

Within-the bodytof the tank I have located a combination trap door and chute at ,A,,, which in the present instance I have strewn-immediately to the side of the door 24; The construction of this is now described.

One of the corrugated sections 11 is out w away to rovide a more or less rectangular .openingm which I have inserted a metallic frame of angle iron cross section to which frame is swingably securiedthe trap dobr 43 having wings l4 extending from the sides thereof, which wings are concentric to the hinge andare designed to swing with in the frame 42. The wings and/trap door constitute a, chute through which the grain can be run' from the tank. It will be noticed" that thewings are provided with lips 4:5whichengage with the upper side of the frame 42 whim the door is swung outwardly thereby holding ,the door in 'alset position.

' this a gate adapted to slide between the I "wings 44, such. gate being held in slidable relation to the tank by means of cross bars 47 secured to the inner side of the section. Liigs48 are cast on the'lower side of the frame 42, which lugs receive the gate when shut. A roddt) is bolted firmly to the gate and passes upwardlyiwithin the tank so that it is easily accessible tls'ough the opening se ate door or chute can alsobe locked by padlock if desired.

The opening 17 in the roof is very long and I consider this a great advantage over openings which I have seen inmany other tanks for similar purposes. -Where a small or square opening only is provided the grain, which is usually placed in the tankthrough a spout, banks up at one side of the tank and consequently puts a great pressurev on that side, while leaving the opposite side thereof altogether free from pressure. With a long opening such as I have provided the tank can. be filled by a spout so that the grain pressure is equally distributed on all sides.

When one des'ires'to load awagon from my tank the Wagon box is first backed. against the tank with the rear end directlybeneath the chute. The driver or teamster then unlocks the trap dooryit it be fastened,

and swings it out over'the wagon box. He next removes the coverl9 and draws the rod {19 upwardly, which motion allows the grain to pass through the chute to the wagon. The wagon box can be filled in this way entirely if the tank be fairly well filled-with grain. However in cases where the grain in the tank does not come much above the level 17 when the cover is removed. The trap of the chute, it will be necessary to load as much as possible through the chute in the manner above described and then load through the door 24;. The door 2 1 will be opened after the pieces 38 and 39 have beenremoved and the wagon will then be backed up against the tank so as to come directly opposite the lower section 32 of the'inner door. As the grain is practically all out of the tank behind the upper section 3l'it is easily swung inwardly' The attendant can then get into the tank and shovel the grain over the section 32 into the box. I

In order to prevent any possibility of the tank bal ing atfthe side where the door is located, fhave secured angle plates 50 to the posts adjoining the beams 27 and 28 to which angle plates are fastened rods51 which pass inwardly and downwardly to the base of the tank where they are fastened to eyes 52 extending upwardly from the base.

Suitable turn-buckles 53 are provided in the rods whereby they can be tightened as desired.

What I claim as my inventionis':- 1. In a grain tank, the combination with the roof thereof having an elongated opening therein radiating from the peak, of a cover closing ovr the opening, and a hoodsecured to the roof and fitting over the end of the cover adjacent the peak, as and for the purpose specified; 2. In agrain tank, a sectional metallic roof supported by roof beams, and having .anelongated opening the combination with a cover over therein with opposing sides turned upperms;-

the upwardly directed edges of the opening, the opening having its sides turned upwardly and backwardly and adapted to fit overjthe upper edges of the plates, and a hood secured to the roof and receiving the .upner end of the cover,-as and 10 for the purpose specified.

Signed at Winnepeg, in the Province of Manitoba, this 10th day of June 1910.

WILLIAM JOHNSTON.
