PATENTED AUG. 13, 1907. H. G. PFOST.
Specification of Letters Patent.
Patented Aug. 13, 1907.
Application filed February 2, 1907- Seri l N 3 To all whom it may concern:
Be it known that I, HARRY G. from, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Fireproof Partitions, of which the following is a specification.
This invention relates to fireproof partitions and my object is to produce a self-supporting partition composed of woven wire provided with stiffening ribs and forming practically metallic studs for the remaining portion of the wire which forms the lathin A further object is to produce a partition of this character which can be erected easily, quickly and cheaply, and which can be manufactured at alow cost.
To these ends the invention consists in certain novel and peculiar features of construction and organization as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying drawing, in which- Figure 1, is a horizontal section of a part of a building provided with a hollow partition embodying my invention. I 3, is a vertical section of a horizontal partition embodying the invention. Fig. 4, is a perspective view of a portion of the partition as constructed in Fig. 1. Fig. 5, is a horizontal section showing a pair of ineeting partitions. Fig. 6, is a detail perspective view of a part of a skeleton channel to receive the ends of vertically arranged partitions.
In the said drawing, 1 indicates a skeleton metallic sheet composed by preference of wire woven or otherwise secured together and said wire sheet is formed with a series of hollow parallel ribs 2 all projecting from the same side of the wire. The wire partition terminates at its side margins in hooks 3, of the same general character and formation as the ribs and also hollqw like the latter.
To produce a fireproof partition or ceiling, a sheet of this partition wire is stretched between the walls 4 of a building, which sheet may consist of a single piece of wire if sufficiently large; ordinarily however, the partition will be composed of a series of strips of the partition wire with the hooks 3 of one section pressed into the adjacent hooks of the next section, it having been found in practice that by simply pressing one hook into another a very secure connection is made, though it is to be understood that after the hooks are thus engaged they may be pinched or clamped together with any suitable tool, to guard against disengagement.
In Fig. 2, a single sheet of the partition wire is shown.
In Fig. 1, a plurality of the sheets of the partition wire Fig. 2, is a similar view of a solid partition. Fig. 1
are shown with the hooks of certain sections fitting in the hooks of the adjacent sections. In Fig. 2 the wire is adapted to be tacked or otherwise secured to the walls 4 and stretched taut, and also secured to the fioor and ceiling. The partition is then completed by embedding it in plaster 5, applied in a manner well known to those skilled in the art. It will thus be seen that a solid noncombustible partition is produced and that the wire sheet thereof forms at once the lathing to hold the plaster and metallic studs to stiffen and strengthen the partition as a whole and brace and support the lathing.
In Fig. 3 the plaster is applied in the usual manner and with the wire sheet embedded therein forms a noncombustible ceiling. The construction shown by Fig. 3 is nothing more than that of Fig. 2 arranged in a horizontal position.
In Fig. l, which shows the preferred construction the partition is hollow and to produce this hollow partition, two sheets of partition Wire or two sheets composed each of a plurality of strips of said wire with their edges hooked together as explained, are arranged in parallel relation with the ribs of one projecting toward the body and between the ribs of the other. The side edges of said parallel sheets may be fastened to walls 4 in any suitable manner as explained in connection with Fig. 2, or, and preferably, may be fitted in the wire or skeleton channel bars 6 secured in any suitable manner to said walls or partitions, it being understood that the edges of said sheets are adapted not only to fit in the channel bars but to be secured thereto in any suitable manner. With this construction the plaster is applied as explained but as access cannot be conveniently had between the parallel partitions a space is left between them. The
partition is therefore hollow with the sides integrallyunited and stiflened by theribs of one bearing against the body portion or the plaster in which said body portion is embedded of the other. By this construction an exceedingly strong and rigid noncombustible partition is produced.
Where two partitions disposed at an angle to each other are to be joined, the hook of one at the end to be connected can be straightened out and bent to form a reverse hook as shown in Fig. 6, to permit said hook to be interlocked with the hook of the other, though it is to be understood that the particular method of connecting the wire partitions is immaterial as they may be wired together or otherwise connected.
From the above description it will be apparent that I have produced a fireproof partition possessing the features of advantage enumerated and I wish it to be understood that I do not desire to be restricted to the exact details of construction shown and described as obvious modifications will suggest themselves to one skilled in the art.
Having .thus described the invention what I claim as new and desire to secure by Letters Patent is:
A self-supporting fireproof partition comprising a pair of skeleton metallic sheets having hollow parallel ribs on their opposed sides, the ribs on the one sheet projecting between the ribs on the other sheet and the edges of the sheets being formed into interlocking hooks and plaster in which the sheets are embedded.
In testimony whereof I ailix my signature, in the presence of two witnesses.
