FIRE-RESISTING PARTITION, WALL, OR THE LIKE.

SPECIFICATION formingpart of Letters Patent No. 694,583, dated March 4, 1902.

Application filed November 6, 1900. Serial No. 35,662. (No model.)

tions, walls, and other like structures, its ob ject being to enable the same to be built very expeditiously and cheaply and at the same time resist more efficiently than heretofore the destructive influences of fire and heat to which they would be subject in an outbreak of fire.

According to my invention I join a number of metal laths to a cross-strip, (or to two or more cross-strips,) the latter holding said laths in parallel position slightly separated from one another. The laths are made, preferably, of band-iron cut into suitable lengths. A series of half a dozen of such laths (joined to the cross-strip) or any other convenient number may compose one piece, and such pieces are applied and fixed to upright columns or girders,so as to fill up the space between them, the direction of the laths being horizontal. I may employ either a double or a single thickness of lathing, according to circumstances.

The accompanying drawings illustrate my invention in several forms.

Figure 1 shows its application to part of a wall of double thickness of lathing, the invention being here represented in a very simple form. Figs. 2, 3, 4, and 5 are modifications of the same idea.

In constructing walls with a double thickness of lathing I take a number of laths a, (see Fig. 1,) and I bend said laths into the shape of a long rectangle, the length and breadth of which is proportioned for the ends to lie between the flanges of the E orIcolumns b. The laths a are joined in groups of half a dozen, or thereabout, to transverse strips 0, which hold them parallel and slightly separate from one another, thus producing a hollow ribbed bodyor cage, which after being dropped into place between the two parallel columns 6 from above is retained within the channels by the flanges of said columns.

any suitable composition at is spread over the outer surface, so as to'completely cover them, together with the columns.

As shown by Fig. 2, the cages may be used with E -.columns c, all facing the same direction and slightly narrower than the cages. To one end of the latter I secure by rivets or the like a E-shaped piece f, the extremities fitting exactly into the channel of the column, and to the other end I attach a piece 9 of somewhat similar shape, but having longer arms, which I bend around the sides of the column. In this manner the cages are held firmly within and to the columns. Rivets, such as h, may or may not be employed, as found convenient. The pieces f g may be dispensed with, if desired, and the cages themselves be shaped as shown by Fig. 3 in an equivalent manner, their ends f being fashioned so as to fit into the channel of the E -columns e and their other ends being first plaited, as shown by g", and the extremities doubled around so as to embrace the flanges of the column, as shown by 9 Another form of my invention consists of taking a single thickness of lathing (see Fig.

4) and dishing it into the shape of a flat-bottomed dish in section or half-cage having flat horizontal rims Two of such pieces (of abouthalf a dozen laths each, as above described) are placed symmetrically against man the foregoing examples cement or like composition 02 is applied to the cages or pieces and also over the exposed surfaces of the columns, the whole affording a perfectly fireproof medium.

In many instances the cement or like composition (1 may be applied beforehand and may be pressed on firmly by hydraulic or IOU other powerful pressure, with the result that it hardens quickly and enables the lathing, together with its coating of concrete, &c., to be applied to the columns, after which only a final coating or finish is needed, requiring less time for drying. The means of fastening need not always be rivets, as before named, but metal tongues or other suitable devices may be used.

Having thus described myinvention, I declare that what I claim as my invention, and desire to secure by Letters Patent, is

1. In the construction of fireproof walls, partitions and the like, the combination of hollow ribbed rectangles or cages formed of bent metal laths and adapted to fill up the space between two vertical columns, and a number of parallel, vertical, shaped columns, in engagement with which the ends of the said cages are held, and alsoa layer of cement or other like material covered finally over the whole, substantially as hereinbefore described.

2. The combination ofa half-cage composed of a series of parallel laths united together by a transverse strip and dished along the edges so as to present a series of flat rims and also a similar half-cage placed symmetrically against same, together with parallel vertical T or columns through the flanges of which the series of fiat rims of one half-cage are fastened to those of the opposite half-cage and therefore also to the said columns, substantially as hereinbefore described.

3. The combination of a series of parallel laths united together by a transverse strip and parallel vertical T or section columns to which the fastening devices are attached which secure the laths in position, together with a layer of cement, or other like material finally applied over the whole substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

WILLIAM SEEFELS.
