Speofication of Letters Patent. p
w Patented Sept. 3, 1918.
Application filed February 14, 1918. Serial No. 217,058.
tion is provided for the block and for the`` bin or wall, and so arranged as to prevent the entrance of mice, moisture and the like, or the escape of grain.
In the drawings:
Figure 1 is a perspective view of a wall constructed of the improvedblocks;
Fig. 2 is a Vertical section through a portion of the wall;
' Fig. 3 is a Vertical section of a modified type of block.
In the embodiment of the invention shown in Figs. l and 2, the wall is composed of hollow blocks 1, the said blocks being formed of plastic material capable of hardening, as, for, instance,rconcret e orthe like, and the blocks are laid in the usual manner in courses withmortar, indica'ted at 2, between the blocks of the courses and between the courses.
As shown, the blocks forming the Wall in Fig. 1 are hollow, and each block is provided at each face with a series of openings 3 and 4, respectively, all of thesaid openings inclining downwardly towardthefiouter faces of the block. Referring to Fig. 2, it will be noticed that the openings at the outer .face of the block incline upwardly toward the interior of the block, that is, toward the hollow, and the openings at the inner face of the block are similarly inclined. Hence whichever face of the block is outward, no moisture can enter, nor can any grain escape, the downward inclination of the openings at the inner face of the wall preventing such escape. to permit the entrance of a mouse, and the wall is thus mouse-proof as Well as moistureand grain-proof.
If desred, the blocks may be as indicated in Fig. 8. In this construction each block 5 has a series of transverse openings, each of which consists of portions 6 and 7 meeting at an angle at lthe center of the block. With this arrangement grain cannot flow up the inclined portion, and moisture cannot pass in from the outside. The openings 6-'7 are also too small for the entrance of mice. Thus there is a perfect ventilation for the interior of the Wall and of the block, while at the same time there is no possibility of the entrance of moisture, nor of the escape of gmin.
A I claim:
A building block having series of openings in the opposite faces'thereof, the openings of each series inclining inwardly and upwardly and being of relatively small diameter and having communication at their adjacent ends. '1 i oAnMAN BAUM'.
The openings are too small
