MONOLITHIC CONCRETE WALD.

To all whom '1' if may concern Be it known that l, JGHN A- Pn'rnnsoN, a citizen of the United States, residing at liclinneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Monolithic Concrete Walls;' and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object; to provide a continuous air space in a monolithic concrete wall. and, to such ends, generally stated, consists of the novel construction and arrangement of parts hereinafter do scribed and defined in the claim. Thisr'esult, from a broad point of view, has been acccnnplished in walls built up of concrete blocks, and in part, it has beenaccoinplished in monolithic or slushed-inconcrete walls, but in these latter walls the best results have not been obtained because of the very incompleteness of the intermediate air space.

My improved wall is illustrated in the accompanying drawings, wherein like charactors indicate like parts throughout the several views.

Referring to the drawings: Figure 1 is a horizontal section taken on the line w m of Fig. 2; through a wall designed in accordance with my invention; Fig. 2 1S avertical section taken on the line -$0 of Fig. 1; and Fig.3 is a transverse verti-' cal section taken through the wall on the line r -av of Fig. 2.

The wall shown has two vertical wall plates and a single intermediate air space, but it will, of course, be understood that the wall may have more than two vertical wall plates and hence more than one intermedi ate air space.

As shown,'the numerals 1 and 2 indicatc, respectively, the inner and outer vertical plates of the wall, and the numeral?) indicates the continuous air space between the same. The inner and outer plates 1 and 2' are tied together by numerous rows of cross ties 4. These cross ties 4c are arranged both in vertical and horizontal rows,

By referring particularly to Fig. 1,, it.

A wall constructed as above described will have a maximum strength with a minimum amount of concrete and will be nearly or quite frost proof, that is proof against the passage of moisture through the wall It, of course,
