Specification of Letters Patent.

Patented Jan. 1.3, 1914..

To all whom it may; concern.

Be it known that 1, DAVID lvloln'rrnu, a citizen of the United ,Cittlltfi, residing at l)e troit, in the county of Wayne, State of llllicliigan, have invented certain new and useful Improvements in CUHIQUtl-BltlttliC011- struction; and I do declare the following to be a lull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being; had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful imprrwenmnts in hollow building blocks de signed .tor the erection of walls, and consists in the constructmn and arrangement of parts hereinafter more fully set forth and claimed.

'i'lhe object 01" the invention is to produce a hollow building blocl: wherein provision is made for preventing to a grez it extent the passe e of moisture thrr ngh said block, and when n the arrangement such as to enable a wall formed of said blocks to be securely bound together by pouring cement or mortar through rc istering vertical passages there- It and for i' ing the blocks of the wall toner by the use ot longitudinal and trans 't-rse reinforcing rods.

The above object attained by the structure ill mired in the accoi'npanying drawings. in hi. -h:

i a e l is a fragmentary View in perspective of a portion of a wall formed of my impijtfitltl blocks F153;. is a fragn'ientary View in plan, showiiig the manner oi i'oriningr an angle in the wall other than a right-angle. l 1g. 3 is a plan View of one of the interi'nediate blocks, also showing" in plan a portion of the succeeding block laid end to end, with respect theretm hint/t is a plan view of one of: the corner blocks. h Fig. 5 is end elevation of one of the li]i(t mediate l; locle Fig. ti is sectional View tl'lrough a, portion of a well laid up of said blocks.

Each of the blocl' as shown in comprises an outer face .i an inner face and a longitudinally ex ofingz partition The portion l of the bioclt forming the outer face thereof is connected to the partit' as [0 so ion :5 by the integral, transverse members 4- tending between and coimecting;- the ends of said. parts, forming a vertical opening 5 tending through the block. The inner face portion 2 of the blockis connected at its ends with the partition 3 by the zigzag transversely extending members 6. These members, it will be seen, have their points of connection with the partition 3 and the inner face portion ofi'set, leaving next to the partition 3 an air space 7, and next to the inner face portion 2 an air space 8. By this arrangement all of two sides ofthe connecting members 6 and a portion of the re maining sides are exposed to the circulation of air, whereby any moisture entering the member Gwill become to a great extent evaporated. before reacl'iing the inner face portion 2 of the block. By connecting the partition 8 and the inner face portion 2 through the medium of the transverse members 6, an air space 9 is formed, which, when the blocks are laid in a wall, shown in Fig. 1, form vertical air fines for the circulation oi air. It will. be noted that the transverse members 6 are hollowed out on top longitudinally of the blocks, as shown at 10, thus providing for circulation of air be tween the spaces 9 of the blocks when the blocks are laid up in wall, as shown in Fig. (3. it will also be noted that the transverse members i are provided in their upper edges with concavities 11, as clearly shown in It is designed to place loi'igitudinally extending tie rods 12 in said concavit'ies, as shown in 1 and 6, to :torm a reinioro inn; connection or tie between. the blocks in the wall.

When a wall is 'lormcd of these blocks they are so placed as to cause the openings 5 thorcii'l to register, thereby forming Vertical passages into which mortar or cement If} may be poured as shown in Fig. (3, to bind the blocks in the wall together. Tn order to allow some of the plastic mortar or cement to enter between the edges of the bearing portions of the blocks, the inner edge ot' the outer t ace p rtion is inwardly beveled, as shown at 14, and the opposite cdu'efot the partition 3 is correspondingly' beveled. as s-(hown at 1.5. This arraugnnnent atl ords a if-shaped opening between the edges of the fare portions l and the partitions when the blocks are placed one upon aiuit'hor, the under taco oi oat-h block being flat, allowing; the mortar or cement 3 which is pom-rd into the rrt'ical passage of the bl ck to fill said oheniml's. as shown at: to in tin. (3. thereby serving to more firmly bind the
