HOLLOW BLOCK.

Patented Feb. 9, 1915.

Application filed July 13, 1914. Serial No. 850,585.

cement and designed for the erection of walls, etc.v

The object'of my invention is to produce a cheap, simple and efficient hollow block for building'and other purposes wherein provision is made for preventing to a great extent, the aasage of moisture through such block, and herein the arrangement is such as to enable awall formed of said blocks to be securely bound together through the in- Sertion of cement or mortar poured through vertical assages therein and for tying the walls oP-the blocks together by the use} of longitudinal and transverse reinforcing rods.

A further object of the invention is to providemeans for strengthening a portion of such blocks and to overcome the liability of breaking the same at such portions.

To these ends my invention consists, generally stated, in the novel arrangement, con-' struction and combination of arts as hereinafter more specifically set orth and described, and particularly pointed out in the claims.

-To enable others skilled in the art to which my invention appertai-ns, to construct and use my invention, I will describe my 1mproved hollow block construction more particularly, referring to the accompanying drawing, in which Figure 1 is a fragmentary view in perspective of a portion of a wall having my improved blocks. Fig. 2 is a fragmentary view showing in plan the mannerof forming an angle in the wall other than a right anglej Fig. 3 is an enlarged plan -view of one ofthe intermediate blocks shown in plan. and portion of the succeeding block aid end to ,end with respect thereto. Fig. 4

5 is an end elevation of one Fig. 6 is a sectional view through a of said blocks.

As shown in Fig. 3 each of the blocks A comprises an outer face 1, an inner face 2 and longitudinal extending partition 3, and such portion or face 1 of the block forming such outer face is connected to said partiportion of the wall formed tion by the integral transverse members 4 extending between and connecting the ends of'said parts, which form a vertical opening 5 extending through such block. The inner face portion 2 of the block A is connected at its ends with the partition .3 by the zigzag transversely extending members 6, and these members have their points of connection with the partition 3 and said inner face portion 2 ofi'set, which leaves next to the partition 3 an air space 7, and next to said inner face portion an opening 8 which forms an air space. In such an arrangement both of the two sides of the connecting members 6 and a portion of the remaining sides are exposed to the circulation of air, so that any moisture entering the members 6 willzbecome to a great extent, evaporated before reach ing the inner portion 2 of the block A. The transverse members (i in thus connecting the partition 3 and inner face portion 2 of the block A form an air space 9, which, when the blocks are laid in a wall, as shown in Fig. l, are ada )ted to form vertical air flues for the circulation of air. The transverse members 6 are hollowed out as at 10 onthe top longitudinally of the blocks A and 4 thus provide for the circulation of air between the spaces 9 of the blocks, when such blocks are laid up in a wall as shown in Fig. 6. The upper edges of the transverse members 4 in the blocks A are provided with the concavities 11 such as shown at Fig. 5 and longitudinally extending tie rods 12 are adapted to be placed in such concavi ties shown in Figs. 1 and 6 to form a reinforcing connection or tie between the blocks in the wall.

In forming a wall of the blocks A they are so placed as to'cause the openings 5 therein to register, which will form vertical passages for the reception of mortar once-- ment 13 that is poured into such passages to thereby bind the said blocks in the wall .to-

iii)

respondingly bmeled at 15 in order to allow some of the plastic mortar or cement to enter between the edges of the bearing portions of the blocks and this arrangement 5 affords a V-shaped opening between the edges of said face portions and said partitions when the blocks are placedone upon the other, as the undcrface of each block is flat, which allows the mortar or cement 13 which is poured into the vertical passages of the blocks to fill said portions as shown at 16, Fig. 6, to thereby serve to more firmly bind the blocks together, and afford a partial cement bearing between the edges of the bearing members of the superimposed blocks. When'the blocks A are laid in a wall and the cement is poured, such blocks are united in a homogeneous mass with respect to the outer portions thereof although the one half of the blocks is left unfilled, which will produce an air space or passage for the circulation of air vertically and transversely of the blocks, thereby eliminating to a great extent the presence of moisture in the inner face 3 of the blocks and dampness.

The wall may be reinforced if desired by vertical rods 17 which are passed downwardly through the vertical passage in the blocks before the cement or mortar is poured therein. and such use of the said rods is illustrated in Fig. 6, while upon the pouring of cement or mortar the longitudinal rods 12 as well assuch vertical rods 17 become embedded thereinvand thereby greatly strengthen the wall to resist lateral pressure. 1

The corner blocks 18 provided with smooth ends such as is shown in Figs. 1 and i are used to enable the wall to be properly finished at the corners The end ortions of the outer and inner F 1 id the partition 3 are caused hid the transverse members that when the blocks A as shown in 3,

A hollow building block having a longitudinal partition dividing the block to form openings through the same, transverse .zig-Zag members connecting said partition with the inner face of such block, and a web connecting the outer end of said members with the inner face of said block.

2. A hollow building block having a longitudinal partition dividing the block to form openings through the same, transverse zigzag members connecting said partition with the inner face of such block for form ing projecting ends onsaid face and an air space between'the same, and a web extending across said air space and connecting the outer end of said members with said projecting ends.

3. A hollow building block having afront face member, a rear face member, a longitudinal partition interposed between said members, a transverse connecting member between said partition and said'front and rear members, the connecting members between the partition and the rear member having offset portions, and a'web connecting the outer end of said offset portions with'the rear member.

4-. A hollow building block having a front face member, a rear face member, a longitudinal partition interposed between said members, a transverse connecting member between said partition and said front and ends.

In testimony whereof, I the/said DAVID. Mcls'ryns, have hereunto set my hand.
