CONSTRUCTION OF CONCRETE WALLS.

Specification of Letters Patent.

Patented Aug. 21, 1906.

Application filed August l, 1905. Serial No. 272,255.

To (1J/Z whom t may concern:

Be it known that I, DAvID EwAnT, a citi zen of the Dominion of Canada, residing in the city of Ottawa, county of Carleton, and Province of Ontario, Canada, have invented a new and useful Improvement in the Construction of Valls of Buildings, of which the following is a specification.

My invention relates to improvements in the construction of concrete walls; and it consists in the herein-described placing and arrangement of the materials used. The object of my invention is to provide a wall that will possess the advantages of a 'Iireproof solid concrete wall and that will at the same time include an air-space behind its inner or lath-andplaster facing, that will be simple and inexpensive in construction, employing light and easilyehandled materiahand, further, that may be finished with the plainest or the most ornamental design.

The process of erecting a wall embodying my invention is fully hereinafter described,

reference being had to the accompanying drawings, in which- Figure l is a plan view, Fig. 2 an outside elevation, Fig. 3 an inside elevation, and Fig. 4 a cross-sectional elevation, of a portion of the wall as in process of construction. Fig. 5 isha part sectional plan view of the finished wa The same letter in the different iigures indicates the same part ofthe structure.

Two rows of light studs A and A/, that may be either of wood or metal, as preferred, are placed in pairs, as shown, and the two studs of each pair are held at such distance apart as will suit the desired thickness of wall by tiepieces B, secured to the studs at convenient distances apart.

The outer edges of the outside studsA are set at a short distance back from the intended outer face of the wall, and gage-blocks O hold a facing-board D at that distance from the studs A. This allows the concrete to iill around in front ofthe outside studs and form against the facing-board the smooth-finished outer face of the wall. The facingboards D are held in place while iilling in the concrete by screws d. The penetration of the wall by heat, cold, or miosture is provided against by an air-space between the concrete and the lath-andplaster course forming the inner face ef the wall. This space is formed by placing a curb-board E equal in thickness to the size of space desired between each pair of studs. (See Figs. l and 3.) These curb -boards are removable and when in use are held in position flush with the face of the inside studs A by cleats F, tacked to the studding. Vhen thc facing-board D and curb-boards E have been set in place, the concrete G is lled in to any suitable depth and may be continued as a course around the building. When such a course of the concrete has set suiiiciently hard, the facing-board D and curb-boards E are raised and securedto the studding higher up, where they will be in position to receive a further course of concrete. The process of laying concrete courses as above described is repeated until the desired height of wall is reached.

Where the floors occur, the inside studs A are out away to receive the joists H, which rest upon them, and as the joists and studding would be preferably of the same thickness there will be no impediment to the raising of the curb-beards E. I indicates the air-chamber between the concrete G and the lath d2, secured to the inside studs AC In the above-described improvements in the construction of concrete walls I claim as my invention and desire to secure by Letters Patent-- A building-wall composed of two separated rows of studs the studs of the opposite rows being tied together and spaced apart in pairs transversely of the wall; and a body of concrete by which the outer row of studs is surrounded, and from the inner face of which the inner row of studs project for some distance to form an air-chamber between it and the lath and plaster secured to said inner row of studs.
