' 1 HoLLow-BuILmNe-BLocK srauc'runnj Be it known that I, WEAVER B. DAVIS, a

icitizen of the United States, anda resident bf the county of Madison and State of Ina 5 diana, have invented a certain new and useful Holl'ow-Building-Block Structure; and I do hereby declare that the following is a; full, clear, and exact description thereof, reference being had to the accompanying d awings, in which like letters refer to like parts.

The object of this invention is to provide alstrong. and durable structure formed of hollow concrete blocks and tie bars lying between the series of blocks and interlocking g ther. It is preferably adapted for use sloulders thereof for tying the same to- 11} construction of silos and like hollow structures where there is an outward thrust or pressure and the structure is made to resist efl'ectually this outward thrust or pressure. To that end the hollow blocks are all alike and are provided with an intermediate vertical longitudinal partition and a shoulder artition and 'rom the'partition so that when the blocks are laid upon each other there is, a space be-- tween the shoulders of the adjacent blocks '30 to receive a-tie bar which surrounds and lies 111%011' the outslde of the ser es of shoulders ich are in line with the intermediate partitions in the blocks. This makes it an extremely strdng structure although built of hollow blocks and since the blocks are similar inform, they may be used anywhere in the structure. p

" The nature of the invention will be understoodfrom the accompanying drawings 40 and the following description and claims.

In the drawings Figure 1 is a perspective view of a silo' embodying my invention,

a portion thereof being broken away. Fig.

2 is a perspective on a larger .scale, showing the relative positions of the blocks and the reinforcing rods. .Fig. 3 is a perspective view of a ortion of the structure adjacent the door w ere the circular tie rod does not extend through the door butis secured to the vertical rod through the door casing,

parts being partially .broken away.

While a silo is shown the inventlon is not necessarily limited to a silo, although it is Specification of Letters Patent.

of peculiar value ina silo or other circular structure.

The structure is made. up of hollow cohcrete blocks 10 and tie bars 11 arranged as shown. The blocks are curved longitudinally to sufiicient extent to suit the curvature of the structure anclhave'an inner wall surface and outer wallsurface and an intermedlate. vertical wall or partition 21.

The block has twoihollow chambers, one be-i. tween the inner wall and intermediate partition and the other between the intermedi ate partition and the outer wall, said chambers opening at both ends of the block, There is an upper surface 14 above the inner chamber or opening and another upper surface 15 above the other chamber or opening, the upper surface 14 being elevated somewhat above the level of the surface 15; so as to leave a shoulder 19 which is in alinement with and constitutes a verticalcontmuatron of the Intermed ate wall, 0r

partition 21. There is a downwardly extending surfacel6 at the underside of the outer portion. of the block with aninner shoulder 18 spaced somewhatout and away from the intermediate wall or partition 21 so that when the blocks are placed upon each other there will be a place left between the shoulders 18 and, 19 of the adjacent blocks for the tie bars 11 which are shown herein as being round. At each end and near the outer and inner surfaces of each block there 13' a vertical groove 20 for plaster and in tel-locking points of the adjacent blocks.

In ,building a structure the blocks are placed upon each other like any other concrete blocks or bricks with plaster 23 uniting the joints. Thus one annular layer of blocks is put in place and then a circular tie rod 11 is placed upon said series of blocks about the shoulders 19. Every fifth tie .rod is continuous and extends across the door opening, as shown in Fig; -1. Theremainin tie rods are secured toivertical rods 22 w ich are embedded in'the door casings 13." With this construction the tie rods cannot expand and the structure cannot enlargeand while they surround'theshoulders 19 of the series of blocks, the structure will resist any out:

ward thrust or stress arising from the contentsof the silo or structure. Then plaster is placed-upon the upper surface of the layer of blocks aiid: mantras bar: and theiz next layer of blocks is superimposed. and plaster is placed on, the ends of the block 'when they 'are fit together, and thus the ,t-proces's is continued until lthe-rstructnreeisaz "completed. The door of the SllQ has casmgtte hmugh avh chtheb 11 pro-1 6mm 'fom the foregoing descriptlon it is obvious that an unusually durable structure can be built in the mannerexplained and with theiblocks' formed as set forth. The

it 7 "outward thrust or stress againstthe inner walljoffthe. silo will press against the inner wallfoftlieblock and will be chiefly resistedby the tie-bars 11 and since they lie against theshoulders ltl and these shoulders are in alin'enjient with the intermediate-par tition 2'1 'and'the" portion of the block lying v inside of'sai'd shoulders is rectangular so that thestrain is' transmitted through the inner wall and the upper and lower walls and throu'ghftheintermediate wall to saidshoulder andyftiebarj' it is seen that such a structure is'fsubstantially as durable and stron asiffthe blocks were solid and it is the o 'jectof thisinvention to make a structure oftlief kind of hollow blocks which is as substantial as jone' of "solid blocks and yet it '-ishollowiso"thatthe jwall will readily dry.

When silos are filled with ensilage there is .considerable moisture" or water in the sameand this-moisture or-water, in blocks of this type,';will"jnot be transmitted, to or rea'ch' the outer ha lf gi' portion of the blocks so that fremainpractically dry and as the ensi'la'ge is removed fromv the silo, the
