CHARLES w. KAISER, 0F NEWARK, nnwa'nnsnrl BUILDING-BLOCK.

Specification of Letters Patent. Patentd sept lfi, 1919.

Application filed February 19, 1917. Serial No. 149,382.

To all whom it may concern:

Be it known that I, CHARLES W. KAISER, a citizen of the United States, residing in the city of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Building-Blocks, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, forming a part of this specification.

This invention relates to building blocks, and has particular reference to building blocks molded or manufactured from cement, concrete, various compositions of a plastic nature, containing cement, clayor other suitable material.

One object of the invention is to provide a block for building purposes, which shall be light, and at the same time, exceedingly strong and durable, and of such construction as to prevent moisture from penetrating the wall, in the construction of which said blocks are employed.

A further object of the invention is to provide a block which may be easily and quickly set in a building wall structure, each block being provided with recesses and a tongue, and with corresponding recesses and tongues adapted for engagement with those of the adjacent blocks, the recesses to be filled with cement or the like, to prevent lateral displacement of the block when laid in courses, thus readily enabling the blocks to be laid in proper alinement.

A further object of the invention is to provide an improved block of the character described, the frame-work of which shall be of a uniform thickness throughout, thus producing a uniform Vertical strain or pressure of weight throughout the entire wall structure.

A still further object of the invention is to provide the bearing face of each block with corrugations or channel ways, so that the corrugations will fit into the corresponding corrugations of the other block, in order to hold the same securely.

Further objects of the invention are to simplify and improve the construction and operation of this class of devices. With these and other ends in view, which will readily appear as the nature of the invention is better understood, the same consists in the improved constructionandnovel ar rangement and combination of the parts, which will'be hereafter fu-llydescribed and particularly pointed out in the claim.

In the accompanying drawings has'been illustrated a simple and some modified forms of my invention, it being however under stood that no limitation is necessarily made to the precise structural details of construe tion therein, but that changes, alterations and modifications within the scopeof the invention, may be resortedto as desired. In the drawings, I i I Figure 1 represents a plan view of my improved block.

Fig. 2 represents an end elevation of the same. c 1 j Figs. 3, 4 and 5 represent plan views of slightly modified forms of building blocks constructed in accordance with -my invention.

Fig. 6 represents a top plan View showing several courses of the blocks arranged to break joints; and I Fig. 7 represents a vertical sectional view one upon the other.

Corresponding parts ures are denoted by hke characters of reference.

the said block, subsequent to molding, may

be subjected to burning or to any suitable hardening or finishing processes, and that the material employed in the manufacture of the block may be mixed with any suitable pigment or coloring material, whereby it may be colored to simulate various kinds of natural stone or other building material.

The blocks are provided with interlocking ends. These ends are cut out so as to interlock with the corresponding ends of the adjacent blocks, and both ends are pro vided with a vertical groove 2, which may advantageously be of semi-circular form, as shown inthe drawings, said grooves serving when the blocks are placed end to end, to form vertical channels for the reception of mortar, as shown at 3 in Fig. 6 of the drawings, or metallic locking rods or keys (not shown) may be employed, thus forming lock joints, whereby the blocks Wlll be on an enlarged scale, of two blocks arranged inthe several-fig;

The improved building block which genfirmly united and held against lateral dis placement. To further promote this end, one end of the block is provided with a vertical groove 4: formed in the face of the cut-away portion of the block, and at the other end, with a tongue 5, said tongue 5 v being designed to have holding engagement with the groove 4 of the adjacent block.

The bearing faces of the blocks are corrugated to form channelways 10, in order to prevent moisture from penetrating the wall, in the construction of which said blocks are employed.

The channelways 10 are preferably painted with an asphalt waterproof paint, whereby the blocks will be firmly united; said channelways serve as guides enabling the blocks to be laid in courses, breaking joints midway of their length with the utmost regularity and accuracy, and in an easy and convenient manner, thus producing a neat and sightly result.

This improved building block can be easily manufactured at a moderate expense, and possesses, in an eminent degree, the qualities of strength, lightness and durability.

The shape is such as to enable the block to be conveniently handled and set in posi tion; and it may be readily molded or formed in close imitation of more expensive building material. lVhile I have shown the preferred form of my improved block in Figs. 1, 2 and 6 of the drawings, the same is susceptible of various modifications. as illustrated in the various figures of the drawings, as for instance, in Fig. 3, the vertical groove 6 may be substituted for the tongue 5, and a vertical tongue 7 substituted for the groove 2. In Fig. l, the vertical groove Sis substituted for the vertical tongue 5, while in Fig. 5, a vertical tongue 9 may be substituted for one vertical groove 2.

Experience has demonstrated that the organization above described is a highly eflicient one, and while the device described is the preferred embodiment of my present invention, I do not care to restrict myself to the exact details of construction, combination and arrangement herein set forth, as

obvious modifications thereof, not involving the exercise of invention, may be made by any skilled mechanic, and such departures from what is herein described and claimed, I consider within the scope and terms of my claim.

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

A building block formed with recessed and interlocking ends, cut out so as to interlock with the corresponding ends of the adjacent blocks, the recessed portion of one end of the block being provided with a vertical groove, and the adjacent or outer end of the, block being also provided with a vertical groove, and the other recessed end being provided with a vertical groove and a vertical tongue, in close proximity to the outer end of the block, one of the vertical grooves in each end of the block designed to register with the corresponding vertical groove in the other end of the adjacent block, whereby vertical channels are formed for the reception of locking means, the vertical groove in the first named recessed end of the block being designed to have holding engagement with the vertical tongue formed in the recessed end of the adjacent block, said block being further provided with longitudinally extending zig-zag tongue and groove interlocking means on the top and bottom.

This specification signed and witnessed this 16th day of February, 1917.
