BUILDING BLOCK.

Application filed September- 22, 1922. Serial no. 589,811.

To all whom it may 00mm: 1

Be it known that I, ARTHUR G. HATCH, a citizen of the United States, residin at Duluth, in the county of St. Louis and tate of Minnesota, have invented certain new and .useful Improvements in Building Blocks, of which the following is a specification.

This invention relates to a new and improved building block and more particularly to a building block provided with wall.

scale as Figu means to facilitate the attachment of inner walls, sheathing or facing boards.

Certain types of blocks have heretofore been made provided with extensions or lugs adapted to have wall board or lath attached thereto and to thus support an inner made of the same material as the body. of the block and have also been made of concrete formed of materialada ted to receive nails or similar fasteners. uch a method of attaching an inner wall is objectionable in single block wall construction since the inner wall, being directly attached to the outer wall is likely to become stained or discolored at the points of contact due to moisture permeating the block. A further difiiculty lies in the fact that such points of contact serve to carry heat or cold through the wall and thus reduce its insulating prop erties.

It is an object of the present invention to provide a block having a portion extendin above its surface, the portion being provi ed with an insulatedcovering.

It is an additional object to provide a block of this character in which the upwardly extending portion or rib is permanently attached to the block and in which the insulating layer is positively secured and maintained in place.

Other and further objects will appear as the description proceeds.

I have illustrated a preferred embodiment of my invention in the accompanying drawin s, in whichigure 1 is a side view of the block;

Figure 2 is a longitudinal section of the block;

Figure 3 is an end view upon anenlarged scale; and

Figure 4: is a section taken on line 4-4 of Figure 1, the figure being upon the same re 3. v The body portion 7 of the block may be These lugs have in some cases been formed of any usual concrete or other blockformin material. The particular block shown 18 adapted to form the inner layer of a wall composed of two oppositely faced layers of blocks. The block is provided upon the face edges directed inwardly of the wall with the recesses 8 separated by the central rib 9. The rib 9 is of the same thickness as the outer rim portion 10 of the block. The block as shown is provided on its outer edge with the groove 11 and its ends are provided with the recesses 12 adapted to. receive transverse bonding blocks.

The vertically extending ribs 13 are shown as composed'of a different'material than the body-7 of the block. These ribs are preferably formed of concrete containin cinders, saw-dust or other material whic renders the mixture adapted to receive and retain nails. A folded strip of insulating material 14 encloses the outer face of the rib 13, the edges 15 of the strip being embedded in the body of the block. This insulating material may consist of various elements, but a heavy water-proof building paper or roofing paper has been found particularly adapted for the purpose.

The wall is built up with the .ribs 13 extending inwardly of the building and the inner wall board or other sheathing is attached directly to these ribs. The insulating material 14 effectively prevents the transmission of dampness and also aids in preventing the transmission of heat or cold. The strips 14 have the additional function of retaining the rib 13 in engagement with the body-0f the block both during and after the formation of the block. It will be understood that the ribs may be pre-cast and placed in the mold in which the blocks are to be cast. When thus formed the strips 14 aid materially in bonding the rib to the block.

While my construction has been shown applied to one particular form of block, it is obviously adapted to various other forms of blocks and may itself be varied to be adapted to such blocks.

I claim:

1. A building block having an exposed exterior surface a portion extending above its surface and a layer of insulating material coverin said portion.

2. A uilding block having a'portion extending above its surface and a layer of insulating material covering said portion, the ed s of the insulatin material being embed ed in the body of t e block.

3. A building block having anexposed exterior surface a portion extending above its surface, said rtion consisting of nailable material, and layer of insulating material covering said ortio'n,

4. A concrete bui ding block having a raised" rib on its surface, and a layer of rater-proof building paper covering said r1 5; A concrete building block having a raised rib on its surface, and a layer of water-proof building paper coverin said rib, the edges of 'the paper being em dded in the body of the bloc 6. A concrete building block having a raised rib. on its surface of nailable concrete, and a layercf water-proof building 20 paper covering said rib, the edges of the $1131! being embedded in the body of the 7. A building block havin an exposed cpncrete exterior surface and having a portlon extending above the block surface, such portion comprising a pre-cast rib of concrete covered with insulating material.

8. A building block having an exposed concrete exterior surface and having a portion extending above the block surface, such portion comprising a pre-cast rib of nailable concrete covered with insulating paper upon its outer surface.
