BUILDING-BLOCK.

Specification of Letters Patent.

Application filed February 15, 1907.

Patented May 25, 1909.

Serial No. 357,449.

To all whom it may concern:

Be it known that I, ROY E. KEAGLE, a citizen of the United States, residing at Lodi, in the county of San Joaquin and State of California, have invented certain new and useful Im rovements in Building-Blocks and I do dec are the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to im rovements in building blocks, and particularly to that class of blocks used in constructing two piece wall structures.

My object is to produce a strong, durable and efiicient block and one which will not permit of the moisture percolating therethrough and thus leaking into the interior of the building. This object I accomplish by means of an elongated main block formed with a projecting tying tongue, said tongue being held outward from said main block by diagonal or oblique arms and forming an air space therebetween; also by such other and further construction as will appear by a perusal of the following specification and claim.

In the drawings similar characters of reference indicate corresponding parts in the several views.

Figure 1 is a perspective view of a complete block. Fi 2 is a top plan view of a section of a wal illustrating the manner of constructing a wall with the improved building blocks.

1 designates the main body of the block which is formed with end projections 2 and a central projection 3, said projection 3 being in alinement with the projections 2, all for the purpose as will appear.

Extending from the ends of the projection 3 are oblique or diagonal wings or arms 4, said wings holding outward a tying tongue 5, there being an air space 6 formed between said projection 3, arms 4 and tongue 5, as appears from the drawings. The upper and lower faces of the block 1, tongue 5 and wings 4 are flush as shown.

In constructing a wall the blocks are arran ed in a two piece wall in alternate rows as shown, the tongues 5 on one row on one piece of the wall being tied with mortar or other material to the ton ues of the next highest row of blocks on t e other piece of the wall, the arms 4 of each side being in alinement with each other as shown.

The scheme of having the arms 4 arranged diagonally is twofold, first, to make the connected distance between the two pieces of the wall the longest possible distance, thus causing any moisture which might percolate the wall to travel the longest possible distance, thus lessening the liability of leakage within the interior of the building. Secondly, to brace and tie the wall in the strongest manner possible, as it is well known that stone or cement will not stand much of a pull or twist, but has enormous crushing strength; any unnatural strain therefore would be converted into crushing strain. The said arms 4 and tongues 5 are further advantageous in that they form an effectual center support for the said wall. Further the construction described permits, as is apparent, of a free circulating air space throughout the wall, thus aiding in preventing the percolation of moisture and kee ing the same cool in summer. Thus it x 1 be seen that I have produced a building block which substantially fulfils the objects of the invention as set forth in the statement of this specification.

While I have in this specification set forth the present and preferred detail of construction of my im roved device, deviations therefrom may e resorted to within the scope of the appended claim without departing from the spirit of my invention.

Having thus described my invention, what I claim as new and useful and desire to secure by Letters Patent is A building block comprising a block proper having end projections extending vertically from top to ottom of the inner face of said block, a center projection on said block proper, such center projection being in substantial alinement with said end projections, obliquely projecting arms extending outward from said center projection and form ing an intermediate air space, and a tying tongue projecting outward from the outer ends of such obliquely extending arms.

In testimony whereof I aflix my signature in presence of two witnesses.

ROY E. KEAGLE.
