FIREPROOF CONSTRUCTION.

Application filed April T 0 all whom it may concern:

Be it known that we, AnoLri-t P. s. \VOHL- nun and ln'nar Wonnranr, citizens of the Specification of Letters Fatent.

United. States, and residents of the borough of Bronx, in the county of New York, city and State-of Xew'York, have invented certain new and useful Improvements in Fireproof Constructions, of which the following is a specification.

Our invention relates to tire proof walls arches and other parts of buildings and its objects are, among otherspto provide a simple. strong and durable metal construction which may be easily manufactured and quickly applied to the building and which will alibi-d a proper hold or key for the concrete, plaster or the like and which will cooperate and combine with fillings of various forms. without material change in its constructiou and arrangement.

To this end our improvements consist in the c mbination and arrangen'ient of parts herein "er described and claimed and illustrated in the accompanying drawings.

in the said drawings, Figure 1 is an enlarged vertical section of a fireproof ceiling embodying our improvements. Fig. 2 is a like section of a complete floor and ceiling (:01i.;1l't.Ctlt 1t embodying our improvements. I} is an enlarged perspective of the metal construction. Figs. l and 5 are details of the binding rods. showing a modilied form of connection between said rods and the lath or netting. Fig. 6 is a cross section of a coi'istruction showing the application of our improvements to a different part of the building. Fig. 7 is a plan view of a modified 'form of the wire lathing of Fig. ig. S is a vertical transverse section of a'donble sheet of the same, on a reduced scale. Fig. 9 is a perspective view of a modified form of the wire lath or netting.

1t) and 11 are enlarged details of the ends of the cross pieces supporting the construction intermediate the I-beams.

The essence of the improvements consists in providing metal or wire lath with corrugations of a certain character provided with binding rods or braces passing across the apexes of the corrugations and secured thereto at these points in such a manner that the structure formed in this manner may he manufactured and applied to the building and used in connection with flat walls or ceilings, arches, columns or parts having other form without modification or Patented.

other adjustment than the shaping of the same thereto and hold the concrete or the like either in hor1- zontal or vertical position, permitting the same to he properly applied thereto or distributed in a manner which will insure strength and durability and the highest elliciency. v

The corrugated lath A preferably consists of a wire mesh but may be perforated sheet metal or the like. The corrugations may be varied within certain limits and can be produced by passing the lath through suitable rollers or in any other desired manner. In Figs. 1 to 3 the corrugations are shown to be regular in form, while'in F 9 they are provided with alternate embossed and depressed portions J and I having plane surfaces H between them. In Figs. '7 and 8 the corrugations are arranged in herringbone fashion andhave the binding rods B running across them on oblique lines. In this modification the corrugations A have their sharp apexes on one side and their blunt apexes on the other side, in one section. while in the other section this arrangement is reversed. This construction insures great. strength and durability. as experiment has demtmstrated that by having alternate sections of this character a stronger and more durable construction is provided.

The rods B are preferably composed of vstout WHQ? but may be of strips of metal havingother cross sectional form. As shown in Fig. 3 they are secured to the apexes of the corrugations by small wires passed around the rods and one of the wires of the lath. As shown in Figs. 1, l and 5 these rods are provided with hooks B to engage the outermost wire of the lath. By employing these tie rods in connection with the corrugated lath strong and yet flexible building unit is provided and at the same time a maxin'ium hold or key for the con-- crete C or other *dlling is provided.

Another important advantage gained by this construction is that it gives free access to all parts of the metal construction and thus permits the filling to be properly packed or tamped whether the metal he in a hot-i. .zontal, vertical or other position. The importance of this advantage is too well appreciated to require further explanation.

In order to support the structure inter:
