BUILDING CONSTRUCTION.

Specification of Letters Patent.

Patented Dec. 1 6,1 913.

Application filed March 3, 1913. Serial No. 751,956.

To lll whom it may concern:

Be it known that I, CHARLES J. lunmxs, a citizen of the United States, and a resident of the city of Manitou, county of El laso, and State of Colorado, have invented certain new and useful Improvements in Building Construction, of which the following is a specification.

My invention relates to improvements in building blocks and has for its object the production of a structure which will be durable and economical in construction, and which may be readily and expeditiously erected.

A further object is the production of a building structure especially adapted for use in the construction of silos.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Figure 1 is a side elevation of a silo embodying my invention, Figs. 2 and 3 are enlarged perspective views of one of the blocks employed in the silo shown in Fig. 1, Fig. 4 is an enlarged transverse section of a portion of the lateral wall of the silo, the section being taken on line m m of Fig. 5, Fig. 5 is a fragmentary section taken on line y-y of Fig. at, and Fig. 6 is a sectional detail of one of the joints shown in Fig. 4.

The preferred form of construction as illustrated in the drawings is embodied in a silo 1 which is of the usual cylindrical form. Said silo is constructed of blocks 2 which are formed of concrete or other suitable plastic material. Each of the blocks 2 is formed with its outer and inner surfaces parallel and with its lateral edges tapering from the center of the block toward the re-- spective ends thereof, the resulting block being of a double-wedge-shaped form.

In constructing the silo the blocks 2 are arranged edge to edge one above the other in parallel vertical lines, the joints of adja cent lines alternating or being staggered, as shown. The peripheral edges of the lower portion of each of the blocks 2 are formed with outwardly projecting beads 3, and the peripheral edges of the upper end portion of each block are formed with recesses 01' grooves 4 as clearly shown in Figs. 2 and 3. When the blocks are arranged in operative position to form a structure, the beads 3 of each block will engage the recesses I of the contiguous edges of adjacent blocks, as clearly shownin Figs. 4, 5 and (S. The heads 3, however, are of cross-scctional dimensions considerably less than the corresponding di mensions of the recesses -'l and so that when the blocks are arranged in superimposed relation or edge to edge, semi-circular spaces will be formed for the reception of mortar or other plastic material which is used in uniting the blocks. The edge surfaces of each of the blocks 2 bearing the heads 3 are rounded as at 5, as shown in Fig. 6 for en gagement with the correspondiuglv curved.

surfaces 6 formed at the edge surfaces of each block bearing the recesses t. iVith this arrangen'icnt angular adjustment of adiacent blocks in order to adapt the same for use in the formation of silos of different diameters is made possible.

The structure which is formed by the blocks 2, when a silo is constructed, is reinforced by encircling metallic hands 7 which are. spaced vertically about the silo structure as shown in Fig. 1. In order to receive the reinforcing bands 7 each of the blocks 2 is provided in its outer surface with a central transversely extending groove or channel 8 and at its extremities with grooves or recesses 9. lVhen the blocks are arranged as shown annular grooves or channels are formed about the silo construction for the reception of the bands 7. Said grooves or channels are of cross sectional dimensions greater than the corresponding dimensions of said bands for the reception of sealing material 10, preferablv mortar, which is arranged in said grooves or channels over said bands in order to protect the latter against the weather and fire. The sealing material is troweled o'fl flush with the outer surfaces of blocks 2, and so that when the silo is complete, the outer surfaces thereof will be smooth and even.

A silo or other similar structure which is constructed as described will be found to be extremely strong and durable. By forming the blocks 2 with their respective ends tapering as described, in placing the blocks in position, during the building operation, the three edges of the end which is inserted into position between the upper ends of blocks next lower will not contact with the corresponding edges of said lower blocks until the former is practically in operative position. This, as will be understood is not the case where the lateral edges of the blocks used in the building are parallel since, where the lateral edges are parallel, the latter will contact with the adjacent edges of the upper ends of the next lower blocks between which it is desired to insert the lower end of the former, immediately upon the lower end of the block being inserted passing below the upper extremities of thc blocks between which the former is being inserted. The present construction is of advantage in that with this arrangement the mortar which has been placed upon the edges which it is desired to unite will not be scraped or disturbed until the block is practically in its operative position. \Yhere the lateral edges of the blocks are parallel, the mortar which has been arranged upon the edges of the lower end por tion of the block being inserted and upon the corresponding edges of the slot or opening into which said end of said block is to beinserted, is disturbed and scraped from position before the block reaches its operative position. With the present construction an effectual seal is rendered possible, this being not the case where the lateral edges of the blocks employed in the building are parallel since in the latter case it is almost impossible to secure an even distribution of the mortar or sealing material along the edges united. Through the provision of annulargrooves or channels for-the reinforcing bands in which a plastic sealing material may be arranged to cover the bands, corrosion of the latter is absolutely prevented and hence the life of the silo ex tended.

\Vhile I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation andmodification without departing from the spirit of the invention.

therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

1. A structure formed of -superimposed blocks arranged edge to edge, each of said blocks being of elongated form with the lateral edges of the respective ends thereof tapering from the center of the block toward the extremities thereof; beads provided at the peripheral edges at one end of the block; and recesses provided at the peripheral edges of the other end of said block, the beads of each block engaging the recesses of menace the contiguous edges of adjacent blocks, stantially as described.

2. A structure formed of superimposed blocks arranged edge to edge, each of said blocks being of elongated form with the lateral edges of the respective ends thereof tapering from the center of the block toward the extremities thereof; beads provided at the peripheral edges at one end of the block; and recesses provided at the peripheral edges of the other end of said block, the'beads of each block engaging the recesses of the contiguous edges of adjacent blocks, said beads being of cross-sectional dimensions considerably less than the corresponding dimensions of said recesses, substantially as described.

3. A structure formed of superimposed blocks arranged edge to edge, the joints of adjacent lines of blocks being staggered, the outer surface of each of said blocks being provided with recesses at the respective ends and intermediate the ends thereof, the recesses intermediate the ends of each block registering with the recesses at the contiguous ends of adjacent blocks whereby,

when said blocks are 1n operative position, circumferential grooves will be formed in the structure registering with the respective ends and intermediate the ends of each block; and reinforcing bands encircling said structure arranged in said grooves, substantially as described.

4. A structure formed of superimposed blocks arranged edge to edge, each of said blocks being formed with its opposite ends tapering, the joints of adjacent lines of said blocks being staggered, the outer surface of each of said blocks being provided with recesses at the respective ends and intermediate the ends thereof, the recesses intermediate the ends of each of said blocks registering with the recesses at the contiguous ends of adjacent blocks whereby, when said blocks are in operative position, circumferential grooves will be formed in the structure registering with the respective ends and intermediate the ends of each block; reinforcing bands encircling said structure arranged in said grooves, said recesses being deeper than the thickness of said bands; and sealin material arranged in said recesses over sai bands to completely inclose the latter, substantially as described.

5. A structure formed of superim osed blocks arranged edge to edge, each 0 said blocks being formed with its opposite ends tapering; t e edges at one end of each pf said blocks being formed with outwardly projecting beads, of said blocks being formed with recesses, the beads of one block engaging the recesses of the contiguous edges of adjacent blocks, said beads being of cross-sectional dimensions considerably less than the ing dimensions of said recesses, the contactsubthe edges at the other end corresponding portions of the contiguous edge surfaces of said blocks being corres ondingly rounded to permit of angular a justment of said blocks, substantially as described.

6. A structure formed of superimposed blocks arranged edge to edge, each of said blocks being formed with its opposite ends tapering, the edges at one end of each of said blocks being formed with outwardly projecting beads, the edges at the other end of each of said blocks being formed with my cesses, the beads of one block engaging the recesses of the contiguous edges of adjacent blocks, said beads being of cross-sectional dimensions considerably less than the dimensions of said recesses, the contacting portions of the contiguous edge surfaces of said blocks being correspondingly rounded, one

- being concave and the other convex, in order to permit of angular adjustment of said blocks, substantially as described,

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
