BUILDIll'G-BLOCK.

Application filed March e, i915.

To all wibo/m t may concern.:

Be it known that l, EDWARD Bosi-mri a citizen oi' the United States, residing at San Antonio, in the county of Bexar and State of Texas, have invented certain new and useful Improvements in Building- Blocks, of which the following is a. :specification.

This invention relates to certain improvements in building blocks and the objects and nature of the invention will be readily understood by those skilled in the art in the light of the following description of the accompanying drawings illustrating what I now believe to be the preferred embodiments from among other formations and arrangements within the spirit and scope of iny invention.

it is an object of the invention to provide a building block whereby a wall or maximum strength and minimum weight may be constructed.

A further object of the invention is to provide a building block of small cost to manufacture, light in weight and cheap to transport.

A still further object of the invention is to provide a building block in which there is the largest possible area oi' mortar bed with simplicity'of structure and minimum weight.

A still further object of the invention is to provide a hollow building block capable of being interlocked in a course and when ttormed in courses the superimposed course interlocking with the course directly beneath it.

The invention consists in certain novel features in construction and in arangements and formation as more fully and particularly pointed out hereinafter.

Referring to the accompanying drawings, Figure l, is a perspective view of a block or iny invention. showing the top of the block.' 2, is a perspective view oi the blockof my invention showing the bottom of the block. Fig. 3, is a vertical longitudinal section of a' portion of a Wall con structed of blocks or' my invention.

In the drawings, L show a block having a top with lugs or ribs a, thereon. These lugs or ribs are so constructed as clearly shown in Fig. 3, of the drawings, as not to increase the thickness of the top wall. This construction whereby the top Wallis of the same thickness 'throughout does away with any Specication of Letters atent.

possibilities 'of unequal expansion or contraction ot' the bloei; duri.A g the. processes ot drying. hollow bloei:

formed to receive the ribs or lugs c? on the top of the block below it when ille bloeit. is placed in position in constructing a wall. It will be seen that the lugs or ribs a.. formed on the *op to cori open bottom airspaces iori if ing walls in the' hollow interior of the block.

Referring now particularly to t oi L) in the drawings, where a. portion of a. well in process oi construction with my blocksi -..i shown. The bloclrs are placed in courses with their open sides or bottoni down their ends abutting. ,A course is then'built upon this mentioned course by placing a series of the blocks with their ends abutting and their open sides down but in Vsuch a manner that the center ci each in the upper course is located` directly above the abutting ends oi the two bloclis inirne diately beneath it. ln this nianner a wall is built up of a series oi' sureriinposed courses, the centers of the blocks in each course being directly above the joining' ends blocks in the course immediately below lt will be seen that due to the end walls and the transverse interior dividing will that placing the blocks in a series of posed 'courses and in the manner described above, that the t `ansvcrse dividing 'vail heing placed directly above the abutting end walls of the blocks beneath it and the abuttingend walls of the blocks in the upper Course being placed directly above the transverse dividing walls of the blocks beneath them that a vertical weight supporting and strain sustaining 'all will be formed by each ci' this series oi',2 vertically alined end valls and interior dividing walls extending throughout the height and length of the wall constructed.

ln building a wall of my blocks great hollow building block, a mortar bed of. large area and peculiar construction, is provided. This mortar bed is formed by the top oi the block and the ribs or lugs o, formed thereon and the cooperation of the open bottom having' the air pockets formed by the dividing Walls andside and end walls with 15 a series of horizontal courses superimposed one above the other. Mortar is applied to the upper surface of a course, which is composed of a series of tops ofthe bloclaand their lugs, and then blocks with their open ends down are placed upon this mortar bed and its attendant mortar :in the position explained hereinbefore.

Each block of the upper course with its air spaces or recesses, formed by the side, end vand interior dividing walls will 'lt down upon the lugs of the blocks beneath y it and as these lugs are positioned so as to coperate or enterthese recesses, it Will be clearly seen that any possibility of lateral or longitudinal slipping of the block being positioned Will be done away with and also any possibility of the block being moved out of alinement after positioning but before hardening or setting of the interposed lmortar will be likewise done away With.

The first mentioned of these facts will most materially aid in the speed and accuracy with which a Wall may be constructed, using 40 my block.

The surrounding' Wall of eachair space or recess when placed upon the mortar bed of my blocks will surround each lug or rib on the mortar bed and lie between the side and end Walls of the lugs Which Walls forming in efiect pockets between them which ..,W,ll Abe filled with mortar on the entry of the surrounding Walls of the air spaces of the block above. rlhe entering of the varil ous walls of the blocks above into these mortar filled pockets of the mortar bed will force the mortar up' and around these Walls so that upon hardening' and setting of the mortar, the block? above will be firmly and rigidly anchored tothe block beneath by its end, side and interior dividing Walls, which 'Walls Will be completely embedded at their ends in a solid mass of mortar. I

A wall maybe constructed of my block in 6@ any number of thicknesses or in any number of superimposed courses as the side and end walls may be used as mortar beds in addition to the most effective mortar beds i rovided by the tops of the bl elia and treir @il or bottoms down and their ends abutting in ,pletely solid or closed as disclosed by the upper blocks upon the mortar beds. How' ever, rfor all practical purposes, the solid Iandclosed mortar bed has been found to give the greatest possible rigidity and strength, but l do not Wish to limit my invention to such a bed.

My invention constituting peculiar hollow building block described in the foregoing pages is most aptly adapted for use in s1lo construction. The block may be made with any degree of curvature or in any other form Without materially causing any complicated or expensive changes in its mode or method of manufacture. Take as an example, a silo constructed of my blocks and the following features will be brought out tending to show its peculiar adaptation to this class of building. Silos are subjected to an unusual and very strong radial tension from the inside tending to bulge and force outwardly the sllo Walls due to the fact that grain, fodder and other compact and heavy materials are stored in its interior. My blocks with their copj erating lugs and air spaces or recesses and with their great and effective mortarbeds overcome this radial stress. Itis readily seen in view of the foregoing description, that this tension or stress Ais completely taken up' and overcome by the ends of the side, end and dividing` walls of the blocks in Contact with the ribs or lugs on the mortar bed formed` on the block directly beneath them. Further, due to the vertically eX- tending Weight supporting and stress bearing walls formed by the alined end Walls and dividing Walls the blocks are materially aided in overcoming this internal radial stress. s

The blocks of my invention are cheaply manufactured, simple in construction, and of the smallest possible weight from which the best results of strength and rigidity can be obtained. Due to their exceeding lightness, they are extremely cheap to transport as Well as to handle in loading and unloading. c

It is evidentthat various changes, variations and modifications' might be resorted to in the forms, constructions and arrangements described Without departing from the spiritand scope of my invention and hence l donot Wish to limit my invention to the exact disclosure hereof.

lid/hat l claim is: A hollow building block open on its under interior dividing; Walls forming airl space, said ribs equal'in thickness to the' spaces therein, said interior Walls and the end, side and top walls of said block of equal thickness throughout, a portion of said top above each of said air spaces pressed outwardly to form a rib o approximately the same outline as the air space below vand of a much smaller etreeJ than said Walls and .top of said block and said ribs forming mortar grooves adapted to receive the depending walls of a superposeol'block, said vmlls occupying" a small aree of the mortar grooves formed by seid ribs Whereby the mortar `placed in said grooves is forced a. distance up and around. said Walls loking them rmly to the top of the lower block, substantially as described.

1n testimony whereof I ailx my signature in presence of tWo Witnesses.
