Attorney Patented Feb. 11, 1930 PATENT OFFICE ROBERT MCGARRAUGH, OF SAN ANTONIO, TEXAS FLOATING FOUNDATION Application filed February 14, 1928. Serial No. 254,261.

The present invention relates to a structure which may be conveniently referred to as a fioating foundation, the same being adapted more particularly for use in association with a structure which is built on ground liable to settling.

By way of introduction, 1 may say that structures which must be built on a natural foundation other than rock, or hardpan, is

liable to uneven settling due to an unbalanced moisture condition caused by the protection from weather by the structure itself to the ground beneath it.

With the customary type of foundation, with the floor joists carried by a concrete grade beam or other support resting upon the ground under the structure, the-settlin g of the outside periphery of the structure, resting upon ground subject to moisture from rains, is greater than at the center, upon ground protected from moisture. The result is that floors are thrown out of level, doors bind, and plaster on the inside walls crack.

It is therefore the object of the present invention to provide a structure which combined the action of steel cross beams with a frame-like exterior concrete foundation wall to avoid buckling, the improved structure having been designed with a view toward properly taking care of stress distribution-by way of equalization of the stresses.

I propose a structure which is efiicient in performance, one which will fulfill the requirements of an invention of this class, a structure which is positive and dependable, and which is characterized by a different arrangement of parts.

In the drawings:

Figurel is a top plan view showing the foundationas constructed in accordance with the present invention.

Fig. 2 is a longitudinal section through the same, and

Fig. 3 is a transverse section through the same.

In carrying out the invention, I provide a concrete wall or foundation structure of frame-like design, the same being generally designated by the reference character a. The side and end portions of this structure are of duplicate design and of the cross section shown better in Fig. 2. As shown here, each portion comprises an upstanding central wall 5 and a base 6, the base extending outwardly beyond the wall as shown to provide a firm and secure footing.

This T-shaped cross section virtually provides inner and outer ledges extending beyond the wail portion 5, and it will be noted from Fig. 1, that on the inner ledge at opposite points, extensions 7 are formed to accommodate short tiers 8 providing rests for the cross beams 9.

The beams are here shown as of I-cross sec tion. The manner in which the smooth result is obtained, is shown in Fig. 3, wherein a portion of the structure is built upon the foundation. In this figure, the reference numerals 1O designate the floor and the reference numeral 7 designates the joist therebeneath, which are supported on the Lbeams 9.

It is believed that a foundation made in accordance with this invention will overcome the objections referred to at the outset of the description, and it will be found entirely el'iicient from a standpoint of stress distribution, for the beams disposed, in the manner shown, serve to carry the weight of the complete building on the outside footing of the concrete foundation.

It is therefore believed that persons skilled in the art to which the invention relates will, upon reading the description in connection with the drawings, obtain a clear understanding of the invention. Consequently, a more lengthy description is regarded unnecessary.

Having thus described my invention, what I claim as new is ROBERT MOGARRAUGH.
