March 18, 1930. D. o. FORMAN BUILDING BLOCK Filed July 27. 1927 jand QEIWZCZIV I Patented Mar. 18, 1930 UNITED STATES DAVID O. FORMAN, 0F MORGANTOWN, WEST VIRGINIA BUILDING BLOCK Application filed July 27,

This invention relates to improvements in building blocks and has for an ob ect the provision of a block whlch Wlll simulate a number of bricks with mortar courses between the bricks, the material representing the mortar being differently colored from the bricks, so that a realistic and pleasing effect will be obtained without the additional expense of striping.

Another object of the invention 1s the provision of a block of the above character having means to space the blocks apart when set, so that the mortar courses between the blocks will be of the same thickness as the imitated courses between the bricks, and it will be practically impossible to distinguish the imitated mortar courses from the real courses.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings Figure 1 is a perspective view showing a number of blocks constructed in accordance with the invention.

Figure 2 is a detail perspective view of a slightly modified form of block.

Figure 3 is a fragmentary section showing the arrangement of the vertical mortar courses between the blocks.

Figure 4 is a view partly in elevation and partly in section illustrating the arrangement of the horizontal mortar courses between the blocks.

Referring to the drawings in detail where in like characters of reference denote corresponding parts, the referegce character 10 indicates a block having one of its faces provided with intersecting longitudinally extending grooves 11 and vertically extending grooves 12. These grooves are arranged so that the face of the block simulates a number of whole bricks and half bricks 13, the grooves 11 and 12 simulating the mortar courses between the bricks.

In order to increase the realistic effect, the body portion of the block which forms the 1927. Serial No. 208,851.

bricks 13 is composed of cement colored to represent bricks of any desired shade, while the bottoms of the grooves 11 and 12 are formed ofstrips 14 of a different color so as to represent mortar of any desired color. The strips 14 thus form the base or bottoms of the grooves 11 and 12. The material which forms the strips 14 is placed in the molds at the time of forming the block, any suitable means being utilized for this pur- 6 pose. For example, one face of the mold may be provided with ribs to form the grooves 11 and 12 and as the material of which the block is formed is placed in the mold,- this material is scraped away from the ribs and the material for the strips 14 placed within these scraped-away portions. An artistic and pleasing effect is thus produced Without the necessity of striping.

The ends of the blocks are provided with projections 16 which extend from the half bricks and these projections abut one another as shown in Figure 1 of the drawings so that the efiect of a whole brick is obtained. The projections 16 are so proportioned as to pro vide a space between the ends of the blocks which is equal to the width of the grooves 11 and 12 and acts as a gage for the vertical mortar courses between the ends of the blocks. Projections 17 extend from the top or bottom faces of the blocks and act to space the blocks apart so that the horizontal mortar courses between the blocks will be in conformity with the remaining mortar courses or grooves 11 and 12. It will thus be practically impossible to detect the imitated courses from the real courses and the face of a building or wall composed of these blocks will present a uniform and pleasing effect.

The block illustrated in Figure 2 has its projection 16 provided with substantially V-shaped notches 18 which form anchor notches for receiving the mortar and act to resist tendency of the blocks to move vertically.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claims.

Having described the invention what is claimed is 1. In a cement building block, a block having its main body portion formed of a cement mixture and having longitudinal and transverse intersecting grooves in one face to simulate brick and mortar courses and strips of a material colored differently from the bricks and forming the bottoms of the grooves of the mortar courses, flat parallel ends for the block and spacing projections extending ,beyond the ends and one horizontal face of the block, the projections at the ends of the block having V-shaped mortar receiving notches therein.

2. In a cement building block, a block having its main body portion formed of a cement mixture and having longitudinal and a transverse intersecting grooves in one face to simulate brick and mortar courses and strips of a material colored diflerently from the bricks and forming the bottoms of the grooves of the mortar courses, and spacing projections extending beyond the ends and one horizontal face'of the block, the first mentioned projections simulating half bricks and providing mortar retaining means where the simulated half bricks abut.

In testimony whereof I afiix my signature.
