CONCRETE BUILDING BLOCK.

Application fl1ed my 23, 1925. Serial No. 82,312.

This invention relates to improvement in concrete building blocks for Wall construction. M object is to make a concrete block, rectangu er and box shaped in form,that will lay a strong hollow wall, having a continuous air-space within it. Each block will lay both faces of the wall at one operation. The Wall is made strong by lugs within each block long enough to overlap or crossbond with lugs on blocks in the courses below and above. My object. is to make a block that will lay a wall in courses, that will keep dry and not frost through, and that is strong enough to build dwellings and other large buildings. A further object is to provide a wall that is suitable to plaster when the Wall is laid. These blocks are preferably made of concrete but may be made of clay.

Referring to the drawings:

Fig. 1 is a horizontal section through a block made in accordance with my invention and F1gure 2 is a pers ective of a section of wall. laid with these locks.

Each block 3 is composed of a T shaped section or tile 4 and a channel generally U shaped, section or tile 5 spaced apart and held together. The two tiles are equal in length and height. The lugs thereof extend perpendicularly across the face of the tiles. The T tile 4 has a lug 6 at the middle between the lugs 7 at each end of the channel tile 5. Each lug projects inwardly towards the opposite tile more than half and less than the whole distance between the two tiles. The middle lug 6 on the T tile is approximately equal in volume to the two lugs 7 on the ends of the channel tile.

The T tile and the channel tile of each block are connected together and held in position by iron tie 'rods 8. Each tie rod has one end embedded in the concrete of a lug and the other end embedded in the concrete of the opposite tile. A suficient number of tie rods are used to hold the parts of the block thus firmly together. The block becomes a unit for the purposes of construe,- tion. This facilitates the making, handling and laying in the wall.

When a course of blocks is laid in a. wall, the blocks in the course next above are each shifted a half block to break or lap the joints as is commonly done. In any course the tiles on one face of the wall are all T tiles and in the opposite face of the wall, all are channel tiles. To preserve the design on the outward face of the wall throughout, the arrangement referred to should be followed.

All lugs are the same length. They overlap or crossbond one course above another. This construction ties the wall together, and gives 1t strength. The air-space within the wall makes it dry inside. The blocks may be finished on both faces in the process of makmg if desired. If only the outside face of the blocks is finished in making, the wall may be plastered after it is laid.

I claim:

1. -A building block comprising a T section and a U section, said sections being arranged wlth the leg of the T between the arms of the U while the cross portions thereof are d1sposed in substantially parallel relation.

2. A building block comprising a T section and a U section, said sections being arranged with the leg of the T between the arms of the U while the cross portions thereof are disposed in substantially parallel relation, the end of the leg of the-T section ,of are disposed in substantially parallel relation, the end of the leg of the T section being arranged in spaced relation tothe cross portion of the U section and the ends of the arms of the U section being spaced from the cross portion of the T section and in alignment with the ends thereof, and means for holding the sections together in such fixed spaced relation.

4:. A building block as set forth in claim 1 wherein the leg of the T is approximately twice as thick in section as either arm of the U but is otherwise of substantially the-same dimensions.

5. A building block as set forth in claim 2 wherein the arms of the one section and the leg of the other section extend toward the respectively opposite sect-ion more than half and less than the whole distance between the two sections.

6. In a hollow wall construction, a plurality of superposed courses of block units, each unit comprising a T-sha ed section and a channel or generally U- aped section arranged with the leg of the T between the arms of the U, and the block units of each course being offset lengthwise in relation to those of the next course above or below whereby to dispose the ar rns of the U sections of adjoining blocks 1n a glven course alongside one another over the leg of a T section of a block in the course next beneath. 1

7. A hollow Wall construction as set forth in claim 6 wherein all of the T sections are disposed in one face of the wall and all of the U sections in the other face.

In witness whereof I have hereunto set 15 my hand on this 26th day of January 1926, at Roscoe, Illinois.
