WALL oons'rnnc'rlon.

Application filed March 30, 1927. Serial No. 179,574.

This invention relates to wall structures and has particular reference to the building blocks or elements which make up the wall, the same being in the nature of an improvement over my prior United States Letters Patent No. 1,362,327, granted December 14, 1920.

The invention comprehends for one of its principal objects an improved means for defining an air circulation space within the wall to insulate the same against heat, cold and'dampness, and to provide where desired a space for the circulation of heat through the wall to act as a conductor for conveying the heat throughout the building.

Other objects reside in the provision of means for insuring a proper alinementof the outer and inner surfaces of the blocks without depending upon theskill of the mechanic erecting the wall.

As a still further object the invention com- .prehends a wall structure including building blocks which are so constructed as to properly receive and accommodate the bonding material while concealing the same on the.

exterior surface of the wall.

Other objects reside in the comparative simplicity of construction, the economy with which the blocks or elements may be produced and the wall erected, and the general efliciency derived therefrom.

\Vith the above recited and other objects in view, reference is'had to the following specification and accompanying drawings in which there is exhibited one example or embodiment of the invention which is in no way intended as a. limitation upon the scope of the appended claims as it is to be clearlyvariations and modifications fall within the scope of sald understood that which properly claims may be resor pedient.

In the drawings- Figure 1 is a perspective view of a portion of a wall constructed in accordance with the invention;

Fig. 2 is a vertical sectional transverse view therethrough; I

Fig. 3 is an inverted perspective view oi one of the building blocks or elements;

Fig. 4 is a plan view of a portion of the wall; r Fig. 5 is a vertical longitudinal sectional view taken approximately on the line 5-5 of- Fig. 4;

ted to when found eX- of the same within the grooves 15.

Fig. 6 is a similar sectional view taken approximately on the line indicated at 6-6 in Fig. 4.

Referring to the drawings by of reference, 10 designates the intermediate blocks and 11 the corner blocks which embody the same general characteristics. The blocks 10 each consist of a pair of laterally spaced portions 12 and 13 which are joined by integral webs 14 and which spacing to-v gether with one of the webs, defines at one end a vertical groove 15,the opposite end being provided with a vertical tongue 16, the tongue 16 of one block beingadapted to fit within the groove 15 of an adjacent block. The tongues 16 are provided with beveled corners 17, which facilitates the engagement Each block portion 12 and 13 is of substantially identical configuration and is formed on its upper face with a longitudinally extending groove 18, while the under face is provided with a depending tongue 19 of less depth than the groove 18, the tongues 19 of one course of blocks being adapted to fit within the grooves 18 of the next adjacent lower course. The tongues 19 arev also provided with beveled lower" corners 20, whereby the same are of gradually decreasing width toward the lower free ends to facilitate the engagement of the tongues in the grooves,

- the remaining upper portion of the tongues,

characters of the faces of" one course of blocks with the faces of the next adjacent upper and lower The bonding In terial 21 is placed in the grooves 18 and the excess or residue is permitted' to flow from the opposite ends of the grooves. The opposite ends of each portion 12 and 13 is formed with a substantially con cave depression which affords a receiving space 23 for the bonding material while the remaining end surfaces 24 are directly engageable, thereby concealing from View the bonding material when the wall is completed.

It will be noted that the space 25 between the block-portions 13 allows for the circulation of air by forming a dead air space, or, if "desired, suitable conduits may lead there- 22 extending vertically, juu

through and outlets therefrom to permit of the circulation of heat through the spaces 25 to act as a conductor for heated air in heating the building.

From the foregoing it will be seen that a wall structure has been devised, which insures surface alinement of the blocks or elements without depending upon the skill of the mechanic erecting the building; that the bonding material while effectually conneeting the blocks or elements, is concealed from view, thereby presenting a neater appearance, and that a wall has been devised having an air circulation space therethrough to act as a conduit fora heating agent or as a dead air' space for insulating the building against dampness or external temperatures.

hat is claimed is:

1. A wall construction including a plurality of courses of building blocks, each comprising laterally spaced portions joined by integral webs and defining air circulation spaces between the portions, the said blocks each having a vertical tongue at one end and a vertical groove at the opposite end for interengagement with similar elements formed on adjacent blocks, the end faces of each block portion having a substantially concave vertical recess, the side edges of which recess are spaced from the outer side faces of the block whereby bonding material received in the recesses between two adjacent blocks is concealed from view.

2. A wall construction including a pluralityof courses of building blocks, each comprising laterally spaced portions joined by integral webs and defining air circulation spaces between the portions, the said blocks each having a vertical tongue at one end and a vertical groove at the opposite end for in terengagement with similar elements formed on adjacent blocks, the upper face of each block portion having a longitudinal groove for the reception of a bonding material and the lower face of each block portion having a longitudinal tongue of lesser depth than the groove to afford a space for accommodating the bonding material, the said tongues and grooves of adjacent superimposed blocks adapted to inter-fit.

3. A wall construction including a plurality of courses of building blocks, each comprising laterally spaced portions joined by integral webs and defining air circulation spaces between the portions, the said blocks' each having a vertical tongue at one end and a vertical groove at the opposite end for interengagement with similar elements formed on adjacent blocks, the upper face of each block portion having a longitudinal groove for the reception of a bonding material and the lower face of each block portion having a longitudinal tongue of lesser depth'than the groove to afford a space for accommodating the bonding material, the said portion of the tongues being of tongues and grooves of adjacent superimposed blocks adapted to interlit, the upper portion. of the tongues being of a size to snugly fit the grooves for insuring proper alinement of the outer surfaces of the blocks.

4:. A wall construction including a plurality of courses of building blocks, each comprising laterally spaced portions joined by integral webs and defining air circulation spaces between the portions, the said blocks each having a vertical tongue at one end and a vertical groove at the opposite end for interengagement with similar elements formed on adjacent blocks, the upper face of each block portion having a longitudinal groove for the reception of a bonding material and the lower face of each block portion having a longitudinal tongue of lesser depth than the groove to afford a space for accommodating the bonding material, the said tongues and grooves of adjacent superimposed blocks adapted to interfit, the upper portion of the tongues being of a size to snugly lit the grooves for insuring proper alinemcnt of the outer surfaces of the blocks, and the lower gradually decreasing Widths toward their lower free ends to facilitate their engagement with the grooves.

5. A building block for wall construction, comprising laterally spaced block portions joined by an integral web and defining when associated with similar blocks, air circula-' tion spaces between the block portions, the

said blocks each having at one end a vertical centrally disposed tongue and at the opposite end a vertical centrally disposed groove, the end faces of each block portion between the groove or tongue and outer side surfaces having a recess for the reception of a bonding material, which end faces when in contact with adjacent blocks conceal the binding material from view.
