Ni BED STATES GUSTAV LIEBAU, OF MAURER, NEW JERSEY FIREPROOF FLOOR AND CEILING.

SPECIFICATION forming part of Letters Patent No. 642,700, dated February 6, 1900.

Application filed November-3 1898. Serial No. 695,366. (No model.)

To all whom it may concern:

Be it known that I, GUsTAv'LIEBAU, a citizen of the United States, and a resident of Maurer, in the county of Middlesex and State of New Jersey, have invented certain new and useful Improvements in Fireproof Floors and Ceilings, of which the following is a specification.

This invention relates ,to certain new and useful improvements in fireproof floors and ceilings, and has for its object the production of such a floor or ceiling in which the use of the usual vl-beams may be dispensed with, which may be constructed with a greater width of span than heretofore considered safe or practicable, and which will be light, strong, thoroughly fireproof, and economical.

To these ends, therefore, my said invention consists in the novel features and in the arrangement and combination of the constitu-.

ent parts, all as hereinafter more fully described, and pointed out in the claims.

In the accompanying drawings, in the several views of which like parts are similarly designated, Figure 1 is a fragmentary perspective view of a floor and ceiling between two supporting or end walls, showing the tiles of the floor or ceiling at one side extending through or across the supporting or end wall and at the other side embedded therein; and Figs. 2, 3, 4, and 5 are end views of two courses of the floor or ceiling tiles, showing my invention and illustrating, respectively, different forms of such tiles.

a represents fireproof bricks or tiles of any desired pattern having formed on-their opposite sides parallel grooves or channels I). When the tiles are laid, the channels or grooves therein on adjacent courses coincide to form continuous transverse channels wholly between the top and bottom faces of such tiles, as clearly shown in the drawings. Each tile, therefore, on each side has grooves or channels one-half the size and shape of the channels extending through the floor or ceiling when the same is laid, and within these channels are embedded metallic strengthening rods or strips 0, the channels in the tiles being of course in each case appropriately shaped to receive the same. The metal rods or strips 0 may be of any desired conformation and as many may be used for each two courses of tiles as may be deemed necessary, depending upon the amount of strength required as well as upon the height of the tiles. I have found in practice, however, that good results are obtained in the majority of cases by using for each two courses two T-iron rods or strips, the lower one of which is inverted, as shown. The practical effect of this arrangement is the embedding between adjacent coursesof tiles of light I-beams, with the central part omitted, its place being taken by the solid walls of the tiles on adjacent courses. I do not, however, desire to limit myself to this construction, as the shape, the number, and the arrangement of the metal strips 0 may be varied at will and still remain within the scope and purview of my invention.

In constructing a building embodying my invention the supporting or end walls cl are laid to the height of the first floor or ceiling. \Vooden centers supported from below are then placed in position, and on these centers the tiles a, in which are embedded the strips 0, are laid in mortar in the usual manner. The tiles and metal strips may be carried across the top of the walls d, as shown at m, Fig. 1, in which case the openings in the tiles may be filled with mortar or cement to afford additional strength to bear the wall above, which may be laid upon such tiles, or the tiles,

. with their inclosed strips 0, maybe embedded in the wall d, as shown at y, Fig. 1. Again, when the latter construction is used the Walls d may be laid up with the recesses or indentations y at the floor-lines, in which the end tiles a may be subsequently inserted.

It will be noticed that by my construction no I-beams are necessary, that the usual tie bolts or rods are dispensed with, and that the structure islight, cheap, and strong, and may be made with a practically unlimited width of span. It will also be obvious that the metal rods or strips 0 may be constructed to serve as anchors by forming the same with bolts on its ends adapted to extend through the supporting or end walls d and to receive outside such walls washers and nuts in the usual manner.

By my invention but one form of brick or tile is necessarily used, thereby rendering the construction more rapid, simple, and economical than where skewbacks, keys,

grooves,forming channels substantially above and below the center thereof and in the same vertical plane, and within the boundary of the said tiles or bricks, and metallic rods or strips located within the channels formed by the said coinciding grooves, whereby the said tiles or bricks are locked together at a point both above and below their center, substantially as and for the purposes set forth.

.2. In a floor or ceiling the combination with suitable end supports, of bricks or tiles, havingformedin their adjoining faces coinciding grooves forming channels one above and one below the center thereof, and a metallic T- iron located within the upper channehand an inverted-T iron located within the lower channel and in the same vertical plane as the upper T-iron, thereby forming in effect I- beams between the adjoining courses of bricks or tiles, substantially as and for the purposes set forth.

3. In a floor or ceiling, the combination with supporting or end walls, of bricks or tiles having a plurality of appropriately-shaped side grooves, coinciding with opposite grooves in the bricks or tiles of the next course, and T- iron strips, the lower of which are inverted, located within the channels thus formed in the same vertical plane, substantially as described.

i. In a floor or ceiling, the combination with supporting or end walls, of bricks or tiles having a plurality of appropriately-shaped side grooves in each side coinciding with the opposite grooves in the bricks or tiles of the next course, and a metal tie rod or strip located within each of said channels thus formed, substantially as described.

Signed at New York, in the county of New York and State of New York, this 22d dayof October, A. D. 1808.

GUSTAV LIEBAU.
