UNITED STATES PATENT OFFICE.
ANDREW J. CAMPBELL, or new YORK, N. Y.
FIRE-PROOF FLOOR.
SPECIFICATION forming part of Letters Patent No. 289,218, dated November .27, 1883.
7 Application filed May 22, 1883. (No model.)
To all whom it may concern Be it known that I, ANDREW J. CAMPBELL, of the city, county, and State of New York, have invented a new and useful Improvement in Fire-Proof Floors and Ceilings, of which the following is a full, clear, and exact description.
Heretofore fire-proof floors and ceilings have been constructed by building arches of brick or of tiling between the fioorbeams; but it has been necessary to construct a platform or use a centering to accomplish the work.
The object of my invention is to. provide for constructing a fire-proof floor and ceiling without the use of platforms or supports; and to that end my invention consists in a joggle-arch of fire-proof material, as hereinafter described and claimed.
Reference is to be had to the accompanying, drawings, forming a part of this specification, in which similar letters-of reference indicate corresponding parts in all the figures.
Figure 1 is a sectional side View, showing my improved devices as applied to floor-beams. Figs. 2, 3, 4:, and 5 represent modifications. Fig. 6 is an end view of one of the struts, and Fig. 7 is a perspective plan view of the flooring.
A A are the fioor-beams, B B B are the joggle-pieces, and C O are the struts of the arch, these parts being all constructed of fire-proof material of any suitable character, and the struts preferably made hollow to save weight. The end pieces or buttresses, B B, serve for supports of the struts upon the beams A, and for that purpose may be of any suitable form or shape. Preferably they are made in the form shown, with one side shaped to fit the web and flange of the beams, and grooved or recessed upon the opposite side to receive the ends of the struts, these grooves being either rounded, of V form, or rectangular, as shown in Figs. 4. and 5, as found most convenient or desirable. The center or key piece, B, is recessed at opposite sides to receive the inner ends of the struts, so that it serves to support the ends. The struts C and blocks or pieces B are rabbeted at their sides, so as to form lap-jointsQand the blocks B B are constructed in length so as to break joints with the struts.
In constructing this floor and ceiling, the end pieces, B, are first put in place, the outer ends of the struts G then inserted, the inner ends raised high enough to receive the center piece, B, and the struts then closed downward. This can be readily done and the sections put in place in succession without building any supporting-platform, as each strut being set in place in turn supports the next.
In some cases the center piece, B, may be dispensed with, as shown in Fig. 3, the inner ends of the struts being made of the proper bevel for fitting closely together. Upon the ends of the struts and at the center wooden pieces or strips 6 e are placed, and the whole then covered with concrete or other suitable material, leaving the inner ends of the pieces 6 projecting for nailing the fioor to. The uner side of the arch may be finished or plastered in any suitable manner, and, if desired,
the struts may be formed to secure a flat ceilng, as shown in Figs. 2 and 4.
This floor is inexpensive, as the pieces forming the arches can readily be molded, and by their use the great expense of erecting plat forms or centering be saved. The work can also be done very rapidly, and when cornpleted the floor is self-supporting in all 1ts parts. In case of the springing of the floorbeams or shrinkage of material used for filling, the struts readily adapt themselves to the change of position without danger 0t falllng out.
Having th us described my invention, I claim as new and desire to secure by Letters Patent 1. The fireproof floor or ceiling consisting of the struts C O and end pieces or buttresses, B B, the parts being hinged or jointed together substantially in the manner described.
2. The combination of the struts O O and joggle pieces B B B, substantially as described, for forming a fire-proof floor or ceiling. as specified.
3. The combination and arrangement, in fire-proof flooring, substantially as described, of the hinged or loose struts, supporting end pieces, B B, the filling of concrete or other suitable material, and wooden strips e.
4. In fireproof flooring, the hinged struts 0, made with rabbeted or flanged edges, so as to form lap-joints and obtain mutual support in the sections, as specified.
ANDREW J. OXMPBELL.
