- BUILDING BLOCK Filed Sept. 22, 1938 Patented July 2, 1940 P ATE-Nr OFFICE 2 Claims.

This invention relates to an improved building block and attachments for assembling the blocks and securing a studding thereto.

It is an aim of the invention, to provide an improved building block having means permitting the blocks to be secured by driven fastenings to a studding, and means for retaining the blocks in their proper relative position.

More particularly it is an object of this invenft tion to provide an improved plastic building block having means permitting the blocksto be secured to the studding of an inner wall by driven fastenings without injury to the block,

3 and tubular means shaped to fit aligned grooves in the blocks and having openings to permit the free passage of an adhesive filler and seal for securing the blocks together and retaining the blocks in proper alignment while being secured.

Other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawing which illustrates a preferred form of the invention, and wherein:

Figure 1 is a side elevational view partly in section showing a few of the blocks assembled on a studding,

Figure 2 is a cross sectional view taken on the line 22 of Figure 1,

Figure 3 is a fragmentary longitudinal vertical sectional view showing the reinforcing member mounted at the joint of three of the blocks,

Figures 4 and 5 are cross sectional views taken on the lines 44 and 55 of Figure 3,

Figure 6 is a prospective view of one of the blocks, and

Figure 7 is a side elevational view of the aligning or reinforcing member.

Referring more particularly to the drawing wherein like reference characters designate like or corresponding parts throughout the different views, I designates generally the blocks having a groove or grooves H extending around their four edges l2 and disposed longitudinally of said edges and intermediate the front and rear faces I 3 and M of the block ID. Grooves II are semicircular or arcually shaped as illustrated in the drawing, but may be made in any other desired shape without affecting the function of the blocks Iii. Molded into the blocks III are strips of fibrous material such as wood, designated l5, which are preferably triangular shaped in cross section and which have one of their edges flush with the rear face M of the blocks ID to receive driven fastenings It to secure the studding or frame H, to which an inner wall of plaster or mallboard, not shown, is attached, to the blocks A tubular shaped member l8 as seen in Figure 7, is provided with a cut-out portion l9 intermediate of its ends. Member I8 is sized to fit the aligned grooves between two of the blocksas best seen in Figures 4 and 5, and may obviously vary in cross sectional shape to correspond to the shape of two of the aligned grooves II.

From the foregoing it will be seen, that a block [0 has been provided particularly adapted for use for building structures andhaving the fastening strip l5 embedded adjacent its inner side to receive driven fastenings to mount a clapboard studding or other framework on the inner faces of the blocks. The blocks ID are laid as seen in Figure l in staggered relationship so that the vertical grooves of every other row are in the same plane. One of the tubular align- :0 ing and reinforcing members I8 is mounted in each of the horizontal grooves ll so that the cut-out portion l9 will be in communication with the vertical grooves formed by the two blocks ID in which the reinforcing member I8 is 35 mounted, as seen in Figure 3. A cementitious bonding material designated is poured into the vertical grooves l l and passes through these grooves and through opening l9 into the members l8 and into the horizontal grooves II to form a seal and binding to coact with members l8 in retaining the blocks in position. As seen in Figure 2, grooves H are in exact alignment forming a complete circle and this is necessary with the use of the members I8, since the blocks must be in proper alignment in order to rest squarely one on top of the other.

Blocks l0 may be made of any suitable material, of any size and shape, with the face [3 of any color and design to simulate brick, stone, plain board or the like. When blocks In of a large size are used they may be employed for constructing the foundation thereby eliminating the concrete form work; and the blocks may be made hollow, if desired to form air spaces. The 5 shape of grooves H and members l8 and I5 may obviously be varied without affecting the invention, and various other modifications and changes may obviously be made and are contemplated without departing from the spirit and ranged in staggered relationship, the edges of said blocks being provided with corresponding grooves disposed in alinement, and tubular members disposed in the horizontal grooves and provided with openings intermediate of their ends to communicate with the perpendicular grooves, for retaining the blocks in alinement and for receiving a plastic binder for securing the blocks together.
