nois,haveinventedanewandusefulImprovey ment in Grain-Elevators, of which the following is a specification.

This invention relates to the construction of the bins of grain-holding parts of grain-ele- My principal aim in the invention has been to produce a more practical construction of reproof grain-'bins than has heretofore beenY devised and one which has the requisite I 5 strength combined with other desirable qualities and capable of being erected at a moderate cost.

In the United States Patent granted to me December 14, 1897, No. 595,391, I show tirezo proof bins constructed of hollow tile strength ened at intervals by horizontal courses of metal beams. The bins in that patent-Were made square; but in my present invention the larger part ot the bins are made cylindric in form, as that form enables me to make the walls stronger and better able to withstand the enormous weight and pressure of the grain. The cylindric form is also advantageous, because the interspaces between adjacent bins are also utilized as grain-holding receptacles and the arched or rounded walls of the bins possess much greater ability to resist the pressure from the grain in such interspacebins than does the at straight wallof a square bin, and hence I have been led in this invention to thus utilize the interspaces as bins; but instead of arranging the eylindric bins with their nearest. points in contact, as has been the custom heretofore, I separate them,

4o so as to greatly enlarge the interspaces and connect them by double walls, each of which is arched or rounded, so as to present a con- Vex surface to the grain. In this manner all the int-erspace-bins are rendered eight-sided,

four sides being formed by the exterior ofthe four adjacent cylindric bins and-the other four sides by the connecting-walls.

The invention further relates to the construction of the walls of the several binsw-that 5o is to say, such walls consist of alternating tile courses,one composed of hollow tile positioned vertically-that is, with their hollow spaces and partitions standing vertically-and the other course composed of tiles laid horizontally and bonding the vertical tiles. In the cylindrical bins the vertical tile are laid in two rows, one inside of another, and the inner row is surrounded by metal vfabric or other equivalent tensile member and the alternating horizontal tile extend across both rows of the vertical tile, so as to firmly unite them. In the connecting-walls of the interspace-bins I employ one row ot the vertical tile in each course in connection with alternating horizontal flat tile and support them by a metal fabric or other compression metal support on the inner face of the wall. In all cases the vertical tile may be and preferably are of much greater height than the horizontal courses, and I lay y them in the manner described because they are thereby best enabled to stand the enormous weight of the superstructure and of the contained grain in the bin.

A still further feature of the invention relates to the construction of the bottoms of the bins, and this, as well as other part-s of the invention, are fully described in the description given below7 and also illustrated in the accompanying drawings, in which- Figure 1 is an elevation of a grain-warehouse containing my invention, Fig. 2 is a plan of the bins. Fig. 3 is a partial vertical section of the bins on the line A A of Fig. 2. Fig. 4f is a partial plan of the bins, partly broken away. Fig. 5 is a partial elevation of one of the bins, partly broken away. Fig. 6 is a section on the line B B of Fig. 5. Fig. 7 is a section on the line C C of Fig. 6.

S and 9 are vertical sections of portions of the bottom of one of the bins, and Fig. 10 is a section on the line D D of Fig. 3.

In said drawings, 11 represents the elevator-or warehouse building; 12 12, the cylindrical bins; 13 13, the interspace-bins, and 14 14 the walls connecting the cylindrical bins and completing the interspace ones. The series of bins may be supported in any suitable way-as, for instance, by the 4I-beams 15 15 and columns 16 16.

The walls of bins 12 are composed of alternate courses of Vertical tile and horizontal tile, as already stated. The former are laid in two rows, as plainly shown at Figs. 3, 5, 6, and 7, the tiles of the outer row being IOO , vertical tile.

indicated at 20 and those of the inner row at 21. -In all these tile the air-spaces 22 and interior partitions 23 stand vertical, thus rendering the tile very strong against downward pressure. Around the inner row I place a surrounding tensile member, preferably of metal fabric 24, and embed it in the cement filling the annular space between the two rows of tile. The ends of the tensile member may be joined or simply lapped, as preferred. The horizontal tile (indicated at 25) are of such dimensions as to enable them to act as bonds to the inner and outer vertical tile and extend from the inner to the outer surface of the Wall and break joints with the In laying the vertical tile those in the inner row break joints with those in the outer row, as at Fig. 6. The bottom courses of the tile are laid in a channel-ring 26, resting on the beams 15, and the courses may be extended to any height desired within practicable limits.

The walls forming the means of connecting the adjacent bins are all by preference made double, one part bowing or arching outward in one direction and the other part bowing or arching outward in the other direction. They also each consist of alternating courses of vertical and horizontal tile, (indicated, respectively, at 30 and 31,) the vertical tile being constructed like tile 2O and 2l and the horizontal tile being like tile 25 except in dimension. On the concave side of all these Walls 30 i`s a course of metal fabric 32, embedded in a layer 33 of cement. They are united to the cylindrical bins by providing the latter with vertical channel-irons 34, adapted to receive the ends of the connecting-walls and such lling-tiles 35 as may be necessary and also by tie-rods 36, extending from one bin to another between the walls 30 and having their heads on the inside of the tensile member 24. (See Fig. 10.) These connecting-walls are supported upon channel-irons 37. By reason of the bowed or arched form of the walls they are admirably adapted to support the grain, and being braced against the convex surfaces of the cylindrical bins the latter form solid abut ments forY them. They also help support the walls of the cylindrical bins against the internal pressnrefrom the grain in the latter.

The bottoms of bins 12 are constructed in hopper shape as follows: a series of radiallyarranged tensile rods 40 are secured to the channel-irons 26 at their upper ends and to a centrally-located ring 4l at their lower ends. Upon the rods 40 are placed a series of rings 42 of graduated diameters at suitable distances apart and preferably tied to the rods by wires 43, and upon these rings is laid a course of metal fabric or expanded metal 44 and above the fabric a course of hollow tile 45. The metal fabric is preferably embedded inV cement 46, and top layer of cement 47 is also applied to the tile. Inside the ring 41 is placed casting 48, serving as a mouthpiece to the hopper-bottom, such mouthpiece being supported by its top ange 49 upon the ring 41. Said-flange is made flush upon its upper surface with the upper layer of cement 47. Said mouthpiece is also provided with an exterior ange 50 at its bottom, upon which a delivery-spout 51 is swiveled. y

If it is deemed necessary, tie-rods 60 may be employed, as shown more particularly at Fig. 4, to strengthen the walls of the cylindrical bins against the pressure of the grain in the interspace-bins. These rods extend across the segments of the bins, which form part walls of the interspace-bins and are preferably secured at their ends by bolt 36 to the channel-irons 34.

While I have illustrated the hopper-bottom as constructed for the cylindrical bins, it will be understood that the interspace-bins may be provided with similarly-constructed bottoms.

I claim- 1. A fireproof grain-elevator, comprising a series of cylindrical hopper bottom grainbins each having masonry walls composed of alternate double-row courses and single-row courses bonding the double-row courses, the double-row courses having aspace between their outer and inner rows filled with cement, and a tensile acting metal member or band placed edgewise in said space and surrounding the inner row, substantially as specied.

2. A treproof grain-elevator, comprising a series of cylindrical grain-bins each having masonry walls composed of alternate doublerow courses and single-row courses bonding the double-row courses,the double-row courses having a space between their outer and inner rows filled with cement, and a tensile acting metal member or band placed edgewise in said space and surrounding the inner row, and a series of double bowed or convex Walls uniting adjacent cylindrical bins, and forming a series of interspace bins, substantially y as specified.

3. A grain-bin having a hopper-bottom comprising courses of material forming an impervious downwardly-tapering hopper and a supporting frame consisting of radial tensionrods secured at their outer ends to the peripheral framework and united at their inner ends to a central ring and a metal mouthpiece extending through and supported by said ring.

4. A grain-bin having a hopper-bottom comprising courses of material forming an impervious downwardly-tapering hopper and a supporting frame consisting of radial tensionrods secured at their outer ends to the peripheral framework and united at their inner ends to a central ring.
