GRAIN-ELEVATOR.

Application filed September 9, 1918.

To all whom 2'25 may concern.-

Be it known that I, HALVER R. STRAIGHT, a citizen of the United States, and resident of Adel, in the county of Dallas and State of Iowa, have invented a certain new and useful Grain-Elevator, of which the following is a specification.

The object of my invention is to provide a grain elevator or storage bin of simple, durable, and inexpensive construction, the walls and partitions of which are all made of hollow tile arranged on the reinforced arch principle, so arranged as to provide a'maximum of storage space and a convenient arrangement of the several bins with relation to the grain elevating and discharge spout, and also to provide a structure of this kind in which the walls and partitions are all on arcs having a relatively large diameter, to thereby avoid the diiiiculties of construction and wide spaces between the adjac nt blocks that are ordinarily present in the construction of reinforced hollow tile walls of this kind in arcs of small diameter.

My invention consists in the construction, arangement and combination of the various parts of the device, whereby the obiects contemplated are attained, as hereinafter more fully set forth. pointed out in my claims, and illust at d in the accompanying drawings, in which:

Figure 1 shows a vertical, central, sectional view through an elevator embodying my invention, onthe'line 1-1'of Fig. 2.'

Fig. 2 shows an enlarged, central, horizontal. sect onal view of same.

Fig. 3 shows a top or plan view .with the roof removed, and

Fig. 4 shows an enlarged. detail view, partly in section, illustrating the means for connecting one of the segmental partitions with the adjacent side wall.

Referring to the accompanying drawings, the outer circular wall of the elevator is formed of hollow tile laid in circular form and reinforced by metal rods laid between the courses. This outer wall is indicated by the reference numeral 10; Spaced apart Specification of Letters Patent.

positioned with relation to the elevator.

low tile with metal reinforcing Wires or rods between the courses thereof;

Another partition wall 14has its ends.

united to the circular wall 11 at points ap-' proximately at right angles to a central line through the elevator between the partitions 12 and 13. This wall is also of hollow tile'rreinforced arch construction, and its central portion stands midway between the center of the elevator and the circular wall thereof. Th s arrangement of the three partition walls 12, 13 and 14 is such that they mutually support and brace each other, and also brace and support the outer wall, and the tile thereof are each laid in are shaped courses of relatively large diameters, so that thin mortar joints may be provided between the tile.

In order to further reinforce the outer wall at the point where the partit on wall 14 is connected to it, I have provided a se-' ries of metal brace rods 15, united at one end to the adjacent end of the partition wall 14. and extended inwardly and united to the adiacent one of the arched partition walls 12 or 13.

In the event that it is desired to divide the-interior of the elevator into more com partments or b ns, I have provided the hollow tile, reinforced, segmental partition walls 16, extended from a point at the in tersction of the walls 14 and 13, or 14 and 12. as the case may be, in a direction substant ally centrally through the space between the walls 14 and 13, or 14 and 12, and the brace rods 17 are applied thereto in the same manner as the brace rods 15 before described. 7

Within the space between the center of the partition wall 14 and the interior of the outer wall, I have erected the elevator chute 18, which is of the ordinary construction, and which extends upwardly above the horizontal partition 19 at the top of the segmen tal partition walls. In this horizontal partition 19 are a number of openings 20, one leading to each of the bins or compartments, and there is also a discharge spout 21 lead ing to a point outside of the elevator, through which grain may be discharged into a car or the like.

For forming a rigid joint at the places where the partition walls connect with the circular wall, I preferably employ the construction illustrated in Fig. 4 which consists in placing a layer of hollow tile 22 across the substantially V-shaped spa e between the intersecting walls, then placing Z-shaped reinforcing bars 23 with one end projected through into the interior of the hollow tile of the partition wall, and the other end projected through into the interior of the hollow tile of the circular wall, and then the space between the partition and the circular wall and the tile 22 is all filled with concrete or the like 24, thus surrounding the said Z-bars, thus securely bracing and uniting the walls and their reinforcements.

The customary weighing platform is preferably placed on the exterior of the circular wall in a suitable shed 26, and the space below it is preferably provided with an inclined floor 27, communicating at its lower end with the interior of the space around the elevator chute. All of the bins or compartments are also provided with inclined floors 28, communicating with the space around the elevator chute, so that the grain from any bin or compartment may be drawn directly into the elevator chute to be elevated to the top and discharged through the pipe 21., and all of the'grain received in the shed'26 may be discharged upon the inclined bottom 27 and elevated through the elevator rhute and delivered into any one of the several bins.

My improved construction has, among others. the following advantages:

The elevator chute is located adjacent to the outer surface of the body, hence the receiving shed containing the weighing platform may be located wholly'outside of the elevator proper, and yet the grain discharged through the floor of the receiving shed'may be conducted directly into the elevator chute, so that noneof the space on the interior of the circular walls need beemployed for the purpose of forming the receiving shed. 1

By my improved arrangement of partition walls, each of them can discharge directly from the inclined floor thereof into the elevator chute and, furthermore, the grain may be delivered into any one of them from the top of the elevator chute readily and easily.

By using the partition walls made on the hollow tile, reinforced arch principle, and

being laid in arcs of large diameter, the

construction work may be readily and easily accomplished, and tight-fitting joints made, and at the same time great strength to the structure is attained because of the manner in which the partition walls overlap and abut and reinforce each other.

The entire structure is so arranged that when the partition walls are made of single layers of hollow tile, any one bin may be completely filled and one or more adjacent bins may be emptied, and yet the strtuture will have suiiicient strength to withstand such strain, because if the pressure is upon the outer surface of any arch, the arch itself will be suflicient to resist the strain. If the excessive pressure is on the inner side of any arch, the reinforcements thereof will be sufliciently strong to withstand the strain.

It will also be noted that what might be called the inner or concave face of every curved partition wall is connected by some the other partition walls, with some sup-* porting means, so that every curved partition is tied and thus reinforced against outward pressure against it.

I claim as my invention:

1. In a structure of the class described, the combination of a reinforced outer circular wall, and a series of partition walls, each formed of a curved reinforced tile arch, said partitions focusing on two common points.

2. In a building of the class described, the combination of a reinforced outer circular wall, two partitions spaced apart from a central line bisecting the outer wall, each partition'being formed of reinforced tile arranged in the form of an arc, the outer surface of the are being adjacent to the said central line, anda third partition having its ends connected to'the outer walls and arranged substantially at right angles to the surfaces of the first'two-partition walls.

3; In a building of the class described, the combination of a reinforced outer circular wall, two partitions spaced apart from a central line,bisecting the outer wall, each partition being formed of reinforced tile arranged in the form of an arc, the outer surface of the are being adjacent to the said cenmentioned partition walls.

l. In a building of he class described, the combination of an-outer circular wall of reinferred tile; two arc-shaped, reinforced partitions having their endsunited to the interior of the circular wall near diametrically opposite sides thereof, said partition walls being arranged with the outer portions tral line, a third partition having its ends of their arches toward each other and spaced apart, a third partition wall arranged substantially at right angles to the other two, with its ends united to the circular wall and its central portions united to the first mentioned partition walls, means for firmly connecting the ends of the said partition Walls with the circular wall, brace rods at the ends of the last mentioned partition, extended inwardly and united to the adjacent portions or the first mentioned partitions, and two intermediate arc-shaped reinforced tile partitions, each arranged with one end adjacent to the intersection of the partitions with each other, on the inner sides of the arches thereof, and extending outwardly to the outer Wall.

5. In a structure of the class described, the combination of a reinforced outer circular wall, a series of partition Walls, each formed of a curved reinforced tile arch, focusing on two common points, said partitions being so arranged as to form an elevator chamber adjacent to one side of the interior of the structure, and a series of compartments or bins, all of which have one end arranged adjacent to the said elevator chamber.
