Application filed January 15, 192%. Serial No. 886,448.

To all whom it may concern:

Be it known that I, OLIVER S. BOWMAN, a citizen of the United btates, and a resident of Colorado. Springs, in the county of El Paso and State of .Colorado, have invented a new and useful, Floor Construction, of which the following is a specification.

My invention relates to floors and my object is to provide means whereby composition blocks are molded, flexibly anchored together and rigidly anchored to a base. Other objects will appear as the description progresses.

For illustrative purposes I have shown an adaptation for molding hexagonal blocks, but I do not confine myself to this particular shape and wish it understood that any rec-- tangular or polygonal blocks may be molded by my components.

Fig. 1 represents a plan view of the sheet metal 1 angle before bending horizontally; Fig. '2, a plan view of said angle after being bent into a component of-a hexagonal mold; Fig. 3, an endv elevation of the angle, drawn to an enlarged scale; Fig tyfragmentary elevations of the angle before bending; Fig.

(5, a fragmentary sectional elevation, showing how the blocks are anchored by the corrugations; Fig. 7, a plan view showing the components secured to the base, drawn to a reduced scale, and Fig. 8, a plan view of thesurface 50f the floor.

Sheet metal angles 1 having longitudinal corrugations 2, with holes 3 therein, in their vertical legs and perforations 5 and notches 6 in their horizontal legs, are bent as shown 'iholes therein,

in Fig. 2 and nailed or otherwise secured to a base as shown in Fig. 7; said base coin prisingboards 7 supported by joists 9 and covered with tar paper 801' other water proof 4o material. Concerte or other composition is deposited in the molds thus formed, and leveled slightly above the. tops of said angles. The contraction incident to settingresults in cracks which uniformly follow the tops of the sheetmetal angles 1 (as shown by the dotted lines 9 in Fig. 8) thus completely separating the blocks. (If desired, the

cracks may be filled with paint or other .water proof material, and thereby sealed 59 against the passage of water.) As indicated in Fig. 6, the sheet metal angle 1, by means of corrugations 2, molds a rib on blockA and a groove in block 'B, thereby flexibly anchoring each block to every adjacent block and rigidly anchoring all of the blocks to the base.

I claim;

1. In a floor of the class described, a sheet metal angle having notches in its horizontal 60 leg and a longitudinal corrugation, with holes therein, in its vertical le'g; for the, purposes set forth.

2. In a floor-of the class described, a sheet metal angle having notches in its horizontal leg, and a longitudinal corrugation, with in its vertical leg, and bent at said notches and holes to form a component of a polygonal mold; for the purposes set forth.
