CONCRETE BLGOK AND WALL.

Application mcd November 10, 1921. Serial Nb. 514,257.

To all lwhom t may concern: Y

v Be it known that l, ARTHUR G. HATCH, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Concrete Blocks and Walls, cation.

This invention relates to a new and improved concrete block and wall design, and more particularly to a block and Wall design in which an inner wall forming material, when secured to the block, provides an additional wall air space.

A. number of types of wall blocks such, for example, as those shown in my prior application, Serial No. 436,638, filed January l2, 1921, are adapted to form walls having horizontallyy extending air spaces. These and other blocks of' the same general type,.

however, provide but a single series of spaces.

lit is highly desirable, in extreme climates, to provide a plurality ot series of wall spaces in order to better insulate the buildings. Further, where inner wall forming material is applied to the block wall, it is often desirable to space this material from the wall in order to prevent discoloration due to dampness in the wall.

ln general, methods et securing inner walls to concrete blocks comprise casting wood or similar material in the blocks when formed; the inner wall or its supporting furring being nailed or otherwise secured to these wood pieces. Such constructions are undesirable in that they complicate the block manufacture, and further, in that they ren der construction not fire-proof.

lt is an object of the present invention to provide new and improved wall block and Wall construction adapted to provide for ready attachment of inner wall forming material, and further adapted to space such inner wall from the main body ofthe block wall.

lt is an additional object to provide construction in which lthe inner wall forming material cooperates with the block wall to form an additional series of air spaces.

lt is also an object to provide blocks which are simple in desi and which can be readily constructed in arge uantities.

Other and further objects wi appear as the description proceeds.

Broadly, my invention comprises a wall of which the following is a. specificonsisting of blocks adapted, when faced toward each other in opposed seri s, to form a wall having air spaces therein. lt further comprises blocks having spaced portions formed thereon extending outwardly from the face of the block for the purpose of separating from the wall face, inner wall forming materials secured thereto.

In the preferred form, these spaced portions are adapted to register in adjacent blocks and form continuous pilasters. These pilasters, together with the block wall and inner wall, form air spaces. ln the preferred form, the pilasters are formed of materia-l adapted to receive nails.

l have illustrated a preferred embodiment or my invention in the accompanying drawings, in which- Figure l is'a perspective View showing'a fragment of wall constructed according to this invention;- f

Fig-.1re 2 is a horizontal section of such wall, the wall having inner wall material secured thereto;

.Figure 3 is a section taken on line 3 3 of` 2; and igure Il is a section taken on line 1 -e of Fi re 2.

Re erring now to the drawings, blocks 5, forming a wall as shown, are provided with the'narrow anges 6 extending along one long side of the block, and wide flanges 7 extending along the arallel side of the block. rlhe ends of t e block are formed with vertically extending thickened portions 8. As shown in the drawings, the blocks are preferably Jplaced in thereverse position in the walls so that'the narrow iiange on one block is opposite the wide flange on the opposite block. Asclear-ly appears in Figures 3 and 4, a ser-ies of horizontal air spaces are thus formed in the wall. Those blocks adapted for use upon the inner side of the wall, are provided upon their outer face with vertically extended projections 9. These projections are spaced apart and stand outwardl beyond the contour of the main body of t e wall. The projections are so spaced that when built into the wall, they will register with those upon adjacent blocks and' form continuous, vertically extending pilasters.

ln the preferred form, the body of the block is formed of any usual concrete mixture while the pilasters are formed of slag, sawdust, cinder concrete, or any other nailable concrete so that the wall forming material may be nailed thereto. This wall forming material may comprise Wall board or ex anded metal or furrmg of any kind. It wil be observed that the wall indicated at` 10 in the drawings is spaced from the main body of the Wall by the pilasters to form vertically extending air spaces 11. The completed wall thus provides two series of air spaces, one extending horizontally and one extending vertically. The wall thus ai'ords very complete insulation and the inner wall surface will not be affected by dampness. The complete wall contains nothing but fire-proof materials.

My construction is capable of many modications to adapt it to varying conditions and it is my intention to cover all such modiications coming within the spirit and scope of the appended claim.

I claim:

A wall comprising building blocks placed in oppositely faced spaced parallel courses, the body of the blocks being formed with similar inner faces, the o posite courses forming horizontally exten ing air spaces between them, the outer faces of the blocks on at least one side of the wall having vertically extending pilasters formed thereon, the pilasters upon superposed blocks forming verticali extending pllasters continuous for the height of the wall, and a sheet of inner wall forming material secured to said pilasters, vertically extending air spaces being formed between the blocks, pilasters and sheet material.

Signed at Duluth, Minnesota, this 24 day of October, 1921.

ARTHUR G. HATCH.
