CONCRETE BUILDING.

Specification of Letters Patent.

Patented Jan. 12, 1915.

Application filed July 2, 1909, Serial No. 505,695. Renewed-June 8, 191,4.- Serial No. 843,910.

To all whom it may concern:

Be it known that I, WILLARD B. FEATH- nns'ronn, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Concrete Buildings, of

- which the following is a specification.

My invention relates to the use of concrete timbers of various shapes and sizes in place of wooden timbers or structural steel, and has for its object to produce strong durable fire-proof buildings at much less expense than isthe case Where brick or cement blocks etc. are used. I accomplish this by manufacturing in the shop by special machinery and appliances, the novel pieces of reinforced concrete which I call concrete lumber, and placing them as described in this specification and shown in the drawings, in which v Figure 1 is a sectional View of a portion of my new building. Figs. 2 and 3 illustrate parts of the roof. Figs. 4 and 5 show the top portion of a piece of concrete studding. Fig. 6 shows an H-beam as used between the first and second stories. Fig. 7 is a sectional view of the ridge-pole. zontal section through X X, Fig. 9. Fig. 9 is an elevation in part of the inner face of the wall shown in Fig. 8. Fig. 10 is a vertical section through Y Y, Fig. 8. Fig. 10 shows an end of one of the T-studs of Fig. 8. Fig. 11 is a perspective view of a part of the wall near the second floor. Fig. 12- shows a T-beam reinforced in the web with a steel rod. Fig. 13 shows how a wall is hold true during construction.

A, Fig. 1, is a piece of T-shaped studding, which rests in fresh concrete in the trough E which in turn rests upon the foundation wall F A is another piece of T-shaped studding forming a portion of the inner surface, as A forms a portion of the. outer surface of the wall. After a series of these inner and outer studs has been placed in position, they are temporarily adjusted, one good way being shown in Fig. 13 in which the nails R are driven through the plugs P into the nailing strips H. This is shown in perspective in Fig. 11. The H-beam E, Figs. 1, 6, 10 and 11 is now placed over the 'top ends of the T-studs A, A, after the trough formed by the projections T (shown more clearly in Figs. 10, 10 and 11), has been filled with fresh concrete in which the horizontal reinforcement U may be cm- Fig. 8 is a hori bedded. The upper part of the H-beam E may now be filled with concrete mortar, and similar T-studs put in place for thesecond story, after which the modified H-beam E, Fig. 1, is adjusted and the trough filled with concrete mortar preparatory to-receivicng the roof timber C, Fig. 1.

The floors of' my new building are constructed of T-beams either erect as B or rial. and is preferably stiffened by wires or rods F which are engulfed by the fresh concrete after slipping into grooves or notches in the ends of the roof members similar to S, Fig. 5. The H-beam 1*), Fig. 6, may also have Wires or rods E designed to engage the slots S, Fig. 5, in the ends of the l'-studs. The object of this arrangement is to provide protection from the elements for the wires E by completely surrounding them with concrete.

The roof timbers C may be shaped and arranged as shown in Fig. 2, thergwebs Q; being reinforced and designed to stiffen the flanges C. The lip C along one edge of the flange is designed to engage the inverted lip C on the opposite edge of the flange of the adjoining timber. In Fig. 3 the lips C are elevated on both edges of the flange and are covered by a sort of secondary ridging F, vF. The junction of roof timb ers of either type C or C may of course be ccmented with suitable material, preferably an elastic weather-proof composition. The bosses or projections D, Figs. 1, 4 and 5 are for the purpose of stifi'ening the T-studs A where they assist in supporting the floor beams B. Similar projections D upon the basement girder D, Fig. 1, are for the purpose of giving increased support to the floor beams B.

I claim:

1. A building having walls constructed of two rows of vertical concrete timbers of approximate T-shape. and having webs and flanges, the timbers being placed back to back, said timbers having on the interior faces thereof, projections forming shelves adjacent the upper ends, the shelves correproximately T-shape,

Zponding in length with the width of the anges and in width approximatel half the timber web width, said shelves of adjacent juxtaposed timbers jointly forming a trough and reinforced concrete in the trough.

2. A building having walls constructed of two rows of vertical concrete timbers of apand having webs and flanges, the timbers being placed back to back, nailing strips along the vertical edges of the webs, inwardly projecting nailing plugs near the vertical edges of the flanges,

for the purpose of facilitating alinementqby like driven through means of nails or the the plugs of one row :of timbers into the strips of the other row.

3. A building having walls constructed of two rows of vertical, oppositely placed, parallel concrete timbers of approximately T- shaped section, having nailing strips H, H", at the corners of the webs and nailing plugs P, P, P near the edges of the flanges, for the purpose of facilitating alinement by means ofnails or the like connecting the plugs and the strips, the points of said plugs projecting from the inner surface of the concrete to prevent full contact of the timbers.

4. A hollow wall constructed of two rows of vertical concrete timbers of approximately T- 'shaped section having nailing strips on, the corners of the webs and nailing plugs near the edges of the flanges, and so placed that the plugs in the flanges of one row are adjacent to the strips on the webs of the other row, the plugs projecting slightly to lessen the contact between the two rows.

5. A building block having longitudinally extending edges-on opposite sides thereof,

nailing strips secured to the block along the.

longitudinal edges whereby when the blocks are assembled, the nailing strip on one side of a block lies in abutting relation to a strip on an adjacent block 'wherebylthe blocks can be secured together through said strips.

6. A building block of angular formation presenting longitudinally extending edges OILOPPOSltG sides thereof, nailing strips secure'd to the block along the longitudinal edges whereby when the blocks are assembled the nailing strip on one side of a block lies in abutting relation to a strip of an adjacent block whereby the blocks can be secured togetherthrough said strips.

7..A building block of plastic material comprising a web having flanges projecting therefrom, the web and flanges providing longitudinally extending edges, nailing strips secured along the edges of the Web and flanges respectively, the nailing strips of a flange of one block being in abutting relation with a strip of the web of an adjacent block when the blocks are assembled to form a wall or floor-whereby adjacent blocks can be united through said strips.
