BUILDING BLOCK on BRICK.
Application filed November This invention relates to a novel lnl-ilding block or brick construction designed for use in walls, buildings, paving or constructions employing building blocks or bricks.
An object of my invention is to produce a building block or brick in which a novel form of interlocking construction is employed for the building up and the strengthening of any Structure or paving em loying the use of my improved building bloc or brick In its composition, by reason of the yleldlng movements permitted between the interlocked blocks without danger of displacement by the freaks of nature or otherwise.
A further object of my building block or brick is to produce a cheap block or brick by using certain earths which may by the ar t of compression, be produced in large quantitles for use in arid sections of the country. 7
These and other objects are attained in my improved and novel building block or brick construction described in the following spec1- fication and illustrated in the accompanylng drawing, in which Fig. 1 is a perspective view of the upper side of a block embodying my invention.
Fig. 2 is a perspective view showing the under side of the building block shown in Fig. 1.
Fig. 3 is an elevational View upon a reduced scale suggestive of a wall constructed from the form of building block shown 1n Flgs. 1 and 2.
Fig. 4 is a fragmental perspective view of a l modified form of block embodying my 1nvention.
Fig. 5 is a perspective view of a mod1fied form of block embodying my invention.
Fig. 6 is a perspective view showing theupper side of a further modification of the block embodying my invention.
' Fig. 7 is a perspective view showmg the under side of the building'block shown in Fi 6.
Fi 8 is a sectional elevational view, upon a re uced scale, of a wall constructed from the fzorm of building block shown in Figs. 6 and Fig. 9 is a view of the outer face, upon a reduced scale, of the wall shown in Flg. 8.
The form of building block shown in Figs. 1 and 2, in its general size may be that of the usual building block or brick. However, the upper and under longitudinal faces, instead of being parallel plane surfaces, are formed 5, 1926. Serial "NO/146.527.
on one face with two humps 24 and 25 which in their nature resemble knobs and are square in formatlon, while the opposite face is formed with two depressions 26 and 27 of the same shape and size as of the humps to be used. The humps 5 and 6are joined by slop,- in faces,28' and 29 respectively and at the s1 es are sloping faces 30, 31 and 32, 33, while at the ends of the block are sloping faces 34 and 35.
The under face of this form of block is made identical to match the upper face thereof, except that instead of being made anaglyphic in facial formation it is made correspondingly diaglyphic so that the building blocks nest properly and interlock. Because of the formation of the block into two square sections of identical size and shape the blocks may be staggered in interlocking relation or may be turned at right angles for bonding purposes and still nest properly.
In Fig. 4 the hump of the form just described has been changed to one of hemispher-- ical form 36. This, although performing the identical functions of the square form, also acts somewhat as a ball andsocket joint in the I laylng up of the wall or paving. The underside of this form of block is diaglyphic to correspond with the anaglyphic side containing the-hemisphere 36.
Fig. 5 shows a further modification which consists of the formation of a' block having octagonal humps 37 instead of square humps as-in'the form shown in Figs. 1 and 2. This is merely a modification which performs in a on similar manner to those already described,
'andis shown principally to illustrate the adaptability of my invention to many varying forms. r
The form of building block shown in Figs. 6 and 7, in its general size maybe that as is found in the usual building block or brick. However, the upper and longitudinal faces, instead of being parallel plane surfaces, are formed in one face with two humps 5 and 6 loo which in their nature resemble knobs and are square, while the opposite face is formed with two depressions 7 and 8 of the same shape as of the bumps used. The humps 5 and 6 are joined by sloping faces 9 and 10 respectively and at the sides of the building block are sloping faces 11, 12 and 13, 14, while at the ends of the building blocks are sloping faces 15 and 16. As these slOping faces .ap

become arched so that their lines of intersection with the lanes of the ends and sides will be curved assliown at 17 to 22 inclusive, while the line of intersection 23 of faces 9 and 10 is also curved. I
The under face of the building block is made identical to match the upper face there- 'of, except that instead of being anaglyphic in facial formation, it is made correspondingly diaglyphic so that the building blocks nest properly and interlock. Because of the formation of the block into two square sections of identical size and shape the blocks may be staggered in interlocking relation or may be turned at right angles for bonding purposes and still nest properly as aforemen- The curvature of the sloping walls 9 to 16 inclusive form a flat at the point of their juncture with humps 5 and 6 so as to function as water deflectors which drain water away from the exterior and joints of the walls water that may seek entrance. Also because of this and-the interlocking feature, the blocks may be laid up with or without binding materials such as mortar and the like, depending largely upon what use the building blocks are intended for. 1
When such a building block or brick is incorporated in. wall building or pavement as for example as shown in Fig. 8, the manner in which the building blocks cooperate is shown to be that of an interlock which produces increased strength while at the same time permitting of bonding if desired.
Thus by means of these or other possible forms of my invention a building'block or brick is obtained in which, whether or not mortar or no binding means is employed the bonding'and interlocking features wi. permit of their use or not depending mainly; upon the employment of the block and the. purposes of the construction for which it is to be used.
Having thus described my invention what.
I claim is 'A building block or brick comprising a sub stantially rectangular formation as to all but two faces, the opposite faces which constitute said exception being respectively anaglyptic and diaglyptic .and -du each other, the shape of said anag yptic face consisting of two elevations spaced apart and from the edges of the faceby surfacesinclin-ed away from the elevations, the shape of the diaglyptic face being formed to fit the anaglyptic face. i w
