.Application tiled March 2, 1900. Serial No. 7,058. (No model.)

To all whom it may concern:

Beit known that I, J AMES B.-CoTro1\i, a citizen of the United States, residing at Dayton, in'the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Building Material; and I do declare the following'to be a full, clear, and exact description of the invention, 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 figures of reference marked thereon, which form a part this specification.

My invention relates to new and useful improvements in building material, and comprises a specially-constructed building-block and means for cementing or uniting such blocks to form one continuous solid wall, which may or may not be provided throughout with Ventilating-openings.

The object of the invention is to provide a building-block which closely resembles freestone in appearance and approximates or equals granite in point of durability.

To these ends the invention comprises means hereinafter described in connection with the accompanying drawings, of which- Figure l is an elevation of a portion of a Wall constructed of building-blocks in accordance with my invention. Fig. 2 is an enlarged plan view of two adjacent blocks,show ing the manner of uniting said blocks. Fig. 3 is a vertical section on the line d ct of Fig. 2. Fig. 4 is a vertical section showing the manner of applying the anchor-rods that are usually employed in brick or stone structures; Figs. 5 vand G, sectional views showing the manner of providing a continuous opening through the continuous cement joints for ventilating the wall. Figs. 7, S, and 9 are plan views of the adjacent ends of blocks, showing modifications in the manner of uniting the ends thereof.

The building-block l is constructed o f cement, preferably Portland cement, and is molded or pressed in suitable dies or molds and given any desirable ornamental surface,\vhich in the present instance is beveled od at the four edges. In each of said blocks there is one or more openings 2eXtending through said blocks,and the upper and lower ends of which are flaring or enlarged in funnel shape and the central part of which is narrow or contracted, so that a suitable entrance-,space is provided for the cement to pass in and through said openings. When the blocks are placed one upon the other in constructing a wall, these openings 2 are in a vertical line with each other, and in laying the blocks cement of a thin or semiliquid consistency is poured therein as each block is laid, as above set forth. In pouring the cement in these openings 2 it may be agitated by means of a suitable implement, and this enables the cement to gravitate through said openings and enter the space between the adjacent upper and lower blocks and fill said space and openings, thus firmly uniting the blocks from top to bottom of the wall. The ends of said blocks are provided with vertical openings 3, which may be constructed in a variety of ways, some ot' which are shown in Figs. 2, 7, 8, and 9, or the adjacent ends of the blocks may be constructed in any way that embodies the prin-v ciple of a male and femalejoint. These end openings 3 do not extend in a vertical line through the entire wall, as in the case of the openings 2, but, on the contrary, the ends thereof are closed by upper and lower blocks. The semiliquid cement is poured between the adjacent ends of the blocks and allowed to enter and till these openings 3, and when said cement sets or becomes hardened there is formed a series of dowels which i'rmly unite the ends of the blocks against any possible lateral movement. When the blocks are thus laid in the construction of a wall, it will be observed that each block does not depend for its security on the mortar or cement as usually applied between the faces of bricks, but, on the contrary,have cement bars, so to speak, which extend throughl them at two points in the body of each block and also which securely unites the ends of said blocks to form one conti nuous horizontal rovir of block smhioh practically become in point' Vof vrgiditylone continuous sill and which have allthe advantages in point of durability of the vcostly stone that is used in the constructionofv the more expensive buildings.

As the construct-ion is shown in Figs. 4, 5, and 6 there is an air space or opening 6 extending through the cement in openings 2, and by means of which the walls may obtain ventilation. The tube 5 is tirst placed in the openings 2 as each block is laid, and thus forms a core, around which the cement is placed. When the cement has become hardened, this tube or core is Withdrawn, thereby forming the air chambers or fiues G, which extend down to the foundation to counteract the climatic changes on the outside, and thus prevent the Walls from becoming damp.

ner in which the anchor-rods 4 may be applied bypassing them through the continuous air-space 6. The anchor-rods 4 are tightened by means of nuts usually applied to said rods.

lIavinfr described 1n invention I claiml. The herein described building-block, consisting ot' a cement block having recesses formed in the ends thereof adapted to receive semiliquid cement by means of which the adjacent ends of said blocks are doweled, and the bodies of said blocks having one or more openings therein ofa funnel-shape struci ture which are adapted to receive semiliquid cement, the said funnel-shaped openings forming continu ons openings extending from the top to the bottom of a Wall and by means of which a continuous body of cement may be placed to rigidly secure said blocks from top to bottom of a Wall, and air-spaces formed in said cement bodies, substantially as described.

-2. The herein-described building material, comprising an oblong rectangular block of cement, having one or more openings 2 in the v body thereof, the upper and lower ends of Referring to Fig. 4, this illustrates the mansaid openings being enlarged and the central portion of said openings being contracted, the said openings being adapted to receive cement in a semiliquid form whereby there is obtained in the construction of a Wall one or more continuous bodies of cement passing through said blocks and extending from the upper to the lower portion of said wall, and air-spaces G formed in said cement bodies, substantially as and for the purposes specified.

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

JAMES B. COTTOM.
