Specication of Letters Patent.

Patented Sept. 24, 1912.

Application tiled September 26, 1910. Serial No. 583,9l0.

To all whom it may concern Be it known that 1, JoHN MrrcHnLL, a citizen ofthe Dominion of New Zealand, residing at lonsonby, in the Provincial District of Auckland,Doniinion of New Zealand, have invented certain new and useful Improvements in Constructions of Building- Walls, of which the following isa specification.

This invent-ion relates to that type of ieinforced building wall construction disclosed in my pending application for patent, Serial Number 555,540, filed April 4, 1910, and involves a somewhat ditl'ereiit ap lication of the reinforcing means as speci cally employed in the above identified invention.

In the present embodiment of my invention, I aim, as heretofore, to eliminate all necessity for employing false work, framing of p'ood, shattering, etc., in the actual building of the wall, and at thc same time 1 so peculiarly combine the reinforcing vertical and horizontal rods, with the blocks or slabs, as they are laid in courses, as to derive exceedingly advantageous results from the stand oint of rendering rigid the construction otPa wall, rendering the latter most substantial in resistin vertical and `horizontal stresses and yator ing a unitary wall in which the blocks and rods are intcrlocked firmly to counteract strain in all directions.

l For a full understanding of the' )resent invention, reference is to be had to tie following description and to the accompanying drawings, in which- I Figure 1 is a front elevation'of a building wall constructed in accordance with the )resent invention; Fig. 2 is a plan view; ltig. 2l is a vertical section of a fragment of a. wall; Fig. 4 is a detail perspective view of one of the building blocks; Fig. 5 is a fragmentary plan view of a modified embodiment of the invention.

Throughout the following detail description and on the several figures of thevdrawings, similar parts-are referred to by like reterence characters.

In the construction illustratedin Figs. 1 to 4 of the drawings, the building blocks 1 ,and 4 are laid in horizontal superposed courses, the blocks of one course being staggered With respect to' those of an adjacent course as shown most clearly in Fig. 1. The

blocks 1 are formed with end recesses 2 and a central or intermediate recess 3. upper edge of the block is provided a longitudinal trench 7 located intermediate the front and rear edges of the block. The blocks 4 are substantially1 of the same form as the blocks 1 excepting that the intermediate vertical recess 3 is omitted in forming said blocks. lVhen a course of the wall is laid by assembling the blocks 1, t-lie ad- 'jacent ends of said blocks abut, forming lopen recesses Q substantially of the saine size as the recess 3 in each of the blocks 1. The abutting ends of the blocks 4 forni recesses 4 similar to the

recesses

3 and 2. Furthermore, when a horizontal course of the blocks 1 is laid, the central vertical recesses 3 in the faces of said blocks are in line with the recesses 4 between the ends of the blocks 4. T he aliiied

recesses

3 and 4 of the respective coursesof blocks are designed to receive vertical reinforcing rods 5, said rods 5 having a firm bearing against the central portion of the blocks 1 of the various courses, and a similar bearing, but not so substantial a one necessarily, against .the end portions of the blocks 4. Laid between the horizontal courses of blocks above described Aare the horizontal reinforcing rods 6, the same being received in the aliiied trenches 7 provided in the upper ed es of the blocks 1 and 4. The rods (3 arc a a ted to hold the rods-fi in the recesses in w ii'cli said rods are received, both vertical and horizontal reinforcing rods beinr thus interlocked with respect to the bloc is against, or on which they are seated.

ln finishing a wall constructed as above described. plaster or other plastic material may be filled into the recesses 2 and 4', said recesses forming aiiexcelleiit key for )lasteiing the wall. 'llie rigid bearing ot the reinforcing means herein set forth against the wall will be readily apparent as well as the peculiar substantial locking of said' renforcing means with said wall.

Under some conditions, the strength of a wall of the type of this invention niayybe materially increased by using crimped horizontal reinforcing rods 6', the. saine being laid in thc horizontal trenches 7 upper siirfaees of the blocksl and upon op iosite sides of the vertical reinforcing rods 5. The strengthening action -ot`1 the in the rods 6 interlocked with the rods 5 with re- .lo with horizontal trenches, and horizontal.

crimped rods received. in said trenches and having their crimped portions in directinterlocking engagement with the Vertical rods.
