Application filed December 6, 1907. Serial No. 405,414.

To all whom it may concern.-

Be it known that we, Gunners MOSS'FMAN and JOHN H. GRANT, citizens of the United States, residing at Hobe Sound, in the count) of Dado and State of Florida, have invented new and useful Improvements in Building- Blocks, of which the following is a specification.

The invention relates to an improvement I in building blocks designed to be assembled or built into a Wall or other form and adapt ed when in assembled relation to provide a series of uninterru )ted air spaces extending throughout the height of the wall.

The main object of the present invention is theprovision of a buildingblock of irregular form so,constructed as to permit the interlocking of the blocks when arranged in an outer series to provide a well, one set or series of blocks being especially constructed to prevent passage of the dampness by capillary attraction.

The invention will be described in the fol lowing specification, reference being had par ticularly to the accompanying drawings, in

which zof the blocks assembled to form a wall.

Figure 1 is a view in plan, showing a seIi ic-s 1 2 is a vertical section on the line 2-2 of Fig, 1. Fig. 3 is a perspective view of one of the blocks. 7

Referring particularly to the accompanying drawin 's, our improved building block is molded in t e usual manner, and of'the usual material, the specific materials for and manner ofniolding the block not being important in the present invention except in the single particular to be hereinafter noted. In form the block comprises two walls, hereinafter termed an outerwall 1. and an inner wall 2, said walls being disposed in parallel spaced relation as shown. materially less length then the outer well, being terminally connected with the ends ol' said outer wall through thc medium of sidewalls 3, which walls project from the outer wall at right angles lo the latter for a short distance and then incline inward]; to their juncture with the inner wall. As thus constructed the block comprises spaced arallcl end walls of unequal lengths and d plicatc side walls which are in part at right angles 1.0 I

i is claimed as new, 1s:----

the end walls and in part at an angle to mid end walls and to the rnghtsanglcd part, all ol drawings.

Hilary altruclimi, capable of l l l The inner Wall 2 is of wall 1 ol' the block forms the lace surface of the wall. Cxpcricncc having proven that these blocks arc, llilolighthe ancdium iifcaplransniittimg dampness through ihcir Walls we have arranged the present construction to avoid this objection. For this purposc we inscrt, during the molding ol' the block, :1 hi 'cr l of pure cement, which, ul'icr inlrdcninpg. materially prevents the cn 'iillsnry :n t ion ol the ordinary wall structure Thcsc laycrs nrc ol equal thickness with the thickncss of the wall, and are preferably disposed in the inclined portion of ouch side wall, so [last pussagc ol' the .rnoisturo through the material ol" the block is practically impossible.

In assembling the blocks to provide a wall they are preferably arranged in two series; an inner and outer series. The shorter and wall 2 of the blocks ol ouch series is arranged in proximate relation, and the inclination of the particular part of the side walls noted is such that when the hlorlis are thus arranged the end wall 2 of each block will lit between the divergent side walls of adjacent blocks of the other section, as will be clearly apparent. from Fig. 1 of the drawings. In this position it will be noted that the end Walls 2 of the blocks oi both series form iractically an unil'lterruptod wall extending l of the structure being constriwtcd, and that the end walls 1 of each block l'orrn additional walls extending longitudinally of the struc ture. 'lhcrc is, therefore, thus irovidcd three spaced series of walls extending longitudinally oi the structure, each separated one from the other by intervening air spaces, and that surface of thc structure directly exposed to the elements being backed by a transverse layer of pure cement to prevent capillary spreading ol the moisture.

It is to be understood, oi coursc, that the blocks are arranged in snpm'imposed relation, the blocks of one series alternating or breakin; joints with the blocks of tho ncixt layer series, as clearly shown in Fig. 1. This arrangement, however, does not intcrl'ere with the hill ellcctivencss of the air space providcd, as will also be apparent from the iigure of the drawings referred to.
