BUILDING-BLOCK.

No. 859,764. I

Specification of Letters Patent.

Patented July 9, 1907.

Application filed January 29. 1906. sssrno. 298,518.

Toolt whom it may concern:

Be it known that I, Lns'rnn W. HAGERMAN, a citizen of the United States, residing at Orchard, in the county of Antelope and State of Nebraska, have invented certain new and useful Improvements in Building-Blocks, of which the following is a specification.

The object of my invention is to provide an improved I construction of cement or concrete block to be used for building purposes and so constructed and arranged that it will produce a moisture proof and water proof wall and which will be light without detracting from its characteristics of rigidity and stability, and which may be readily handled and hauled without danger of breakage.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which: 1

'Figure 1 is a perspective view of several building blocks embodying my invention. Fig. 2 is a similar view of one of said blocks showing it in condition for hauling and handling. Fig. 3 is a longitudinal sectional view. Fig. 4 is a transverse sectional View. Fig. 5 is a horizontal section of a portion of one of the blocks, on a reduced scale. Fig.6 is a detail perspective view of one form of tie that may be employed.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

My improved building block may be formed of cement or concrete .or any analogous material and preferably consists of one piece or integral structure of oblong shape as ordinarily employed in building constructions, but not necessarily of such shape. It comprises two sections or members 1 provided with fiat top and bottom edges 2 and 3 respectively, and connected together by means of laterally extending nibs or wings 4, preferably two in number and located near one end of the entire block. In each of these connected wings 4 there is embedded a preferably metallic plate 5 which may be of zinc or any other desired moisture proof metal or material and is preferably of such material as to be pliable without danger of breaking. Each plate 5 is provided with an opening or slot 6 located entirely with its margin and through which the preferably metallic tie 6 extends as shown best in Figs. 4 and 5. The tie is-designed to effectively secure the two sections or members of the block together as well as to fill the slot 6 and prevent moisture from passing therethrough from one section of the block to the opposite section and in the construction of the tie shown in the said views referred to the tie 6 is provided with one or more apertures 6 through which the concrete may extend. Or as shown in Fig. 6- the tie may consist of a II-shaped member 9 the ends 10 of which are designed to extend through the slots 6 in the metallic plate.

they extend beyond the side edges of the wings and also both above and below the same The laterally extending and connected wings 4,01 the two sections or members of the block, produce in the completed block two end air spaces 7 and a middle air space 8 which is bound. on either side by the wings 4. In a wall, where my improved blocks are laid end for end it will of course be understood that the end air spaces 7 are also closed by the abutting ends of the blocks. The middle air space 8 is in the preferred proportion of the parts, approximately twice long as the end air spaces 7 plus the width. of the wings-so that when the blocks are laid one upon the other in the usual staggered or alternate arrangement employed in building constructions the zinc or other spacing plates 5 of two adjoining blocks are intended to be within the central air space of the overlapp ng block just. above. Hence the mortar will be divided, and the plates will not be bent down by the pressure of the block laid on top.

In the manufacture of my improved building block, it is preferred to embed the spacing platcs 5 in the coment or concrete and form the blocks at one and the same operation, whereby there is produced a single integral structure which Will possess a maximum of rigidity or stability. As the spacing plates 5 are of zinc or some other metal or material which possesses sufficient pliancy to permit of being bent without breakage and yet sufficiently stiff to withstand accidental bending and be self sustaining I prefer to bend the projecting upper and lower ends of the plates down upon the respective top and bottom edges of the blocks when the blocks are initially formed so that the blocks may be hauled from place to place and handled Without danger of injury to the said plates. It is to be understood however that these plates are straightened at their up per andlower ends so that such ends will project in the manner before described preparatory to placing the blocks one upon another to form a wall.

From the foregoing description in connection with the accompanying drawings it will be seen that I have provided an improved construction ofcement or concrete block which embodies one integral structure having offset portions or wings that are connected together to produce two longitudinally extending sections or members with air spaces between them, the said wings or offsets having embedded therein zinc or other plates that project both above and below the flat edges of the block and project into the said air spaces of other blocks. Hence there are no mortar connections between the outer and inner walls or sections of the blocks, and a completed wall that has been built with my improved block will, it is manifest, be practically constructed with an outer portion having no mortar connection with the inner portion,- said two portions being spaced from each other with air spaces and the said zinc plates 5 so that moisture will be precluded from entering through the interstices between the blocks.

Having thus described the invention what is claimed as new is:

1. A block of the character described, comprising two,

longitudinal sections or members provided with olaet connected wings whereby to produce air spaces between said sections and pliable and selfsustained plates embedded in said wings with their ends projecting above the said sections, whereh'y when the said blocks are laid in courses with an alternate arrangement, the projecting ends 0! the said plates will extend into thenir spaces 0! the blocks above and prevent moisture from the wet mortar irom passing over one sectionot the blocks to the opposite section;

2; -A block of the character described, provided with air spaces and with embedded moisture proof plates of pliable material that project above the upper plane of the bloclr and are designed to enter the air spaces of similar blocks above, the material of which said plates'are formed being such that the projecting portions of the plates will be sell-sustaining, as and for the purpose set forth.

in testimony whereof I a'flix my signature in presence of two witnesses.
