' METALLIC FO-RM ED SHEET.

SPECIFICATION forming part of Letters Patent No. 748,634, dated January 5, 1904. Application filed May 1, 1902. Serial No. 105,450. (lilo model.)

To all whom it may concern.-

Be it'known that we, JOHN H. MURPHY and ERVIN M. CAMP, citizens of the United States, and residents of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Metallic Formed Sheets; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates more particularly to a metallic formed sheet and adapted to be used in a building construction of a fireproof nature and, if desired, to provide a construction impervious to water.

The object of the invention is to provide a light-tension member comprising a stilfened plate or sheet adapted to receive on one or both sides thereof a compression member of plaster, mortar, cement, or the like and which is particularly'adaptable for constructions in which great strength is to be obtained with minimum weight and thickness.

The invention consists in the matters here-- inafter described, and more fully pointed out and defined in the appended claims.

In the drawings, Figure 1 is a plan view of sheets embodying our invention and illustrates the manner or convenient method of splicing, Fig. 2 is a transverse section of the same. Fig. 3 is a longitudinalsection of the same. Fig. at isa plan view of the same, showing a reticulated material secured thereon. Fig. 5 is a transverse section illustrating one method of attaching the wire mesh. Fig. 6 is a modified form of the sheet, showing the same partly embedded in plaster or mortar. Fig. 7 is a transverse section of the same.

As shown in said drawings, A indicates a sheet of soft steel or other. suitable material rolled or pressed to provide the keys B and B, which, as shown in Figs. 1, 2, and 3, extend longitudinally of the sheet in lines parallel with the edges of the sheet and project from opposite surfaces of the sheet. As shown, said keys are oblong in shape and are provided with comparatively abrupt side and end walls. The keys of the adjacent longitudinal lines of keys are arranged staggering with each other laterally of the sheet and are equal distances apart, thus greatly facilitatin g the splicing of said sheets together, inasmuch as the keys at the end of one sheet will coincide and interfit with the keys of adjacent edges of the other, as shown in Figs. 1, 2, and 3, in which the sheets A, A, and A are shown so lapped together. If preferred, the sides or ends or both the sides andends of one or more of the keys along the lap may be pressed inwardly, as shown at b, tending to lock the two sheets firmly together and making acomparatively rigid and tight joint.

Means are provided for securing and supporting on the sheet a reticulated structure of wire or other suitable material, as shown in Figs. 4 and 5, in which, as shown, the reticulated structure is a wire net D, of a familiar form, having a large mesh and which may be secured upon the sheet in many different ways. One convenient method is to cut the bottom of the key to form an integral tongue of metal I), which when bent upwardly, as shown in Figs. 1 and 4, admits of engaging the net thereon. If preferred, metal clips F may be secured over the wire mesh and gripped upon the key, acting to bind the net firmly in position. As shown in the construction illustrated in Fig. t, the clip engages over the mesh or wire net and is provided with inturned ends which engage in indentations in the sides of the key. Obviously, if preferred, said clips may be inserted inside the key, as indicated by F in Figs. 4 and 5, in which is shown the wire-forming the clip bent upwardly to a point above the normal plane of the sheet and the ends thereof engaged in indentations in the sides of the keys. Obviously said clips may be engaged in the ends of adjacent alined keys, as indicated by. F When cement, plaster, or like material (indicated by G) is applied on the surfaces thus prepared and pressed through the reticulations of the net, the same fills the keys entirely and by the pressure against the sheet closes the material behind the net and entirely embeds the wires in the mortar, the wires serving to bind the mortar to the sheet.

In the construction illustrated in Figs. 6 and 7, from which the reticulated material is omitted for convenience of illustration, the sheet is formed, as before described, with 0ppositely-directed keys B and B The bot-- toms of said keys, however, are out and turned inwardly, forming the inwardly turned flanges 5 adapted to permit the mortar or plaster to form a clench therein. Adjacent to each key on each side thereof are formed the' flanges a a constructed by slitting the metal parallel with the sides of the keys and adja-' cent thereto and pressing or forming the cut edge of the sheet outwardly sufiiciently to perwith or Without the reticulated material.

Pressure being applied on the compression side of the structure, the strains due to such pressure are equalized and transferred from one member to the other. The frequent rises and depressions in the tension-plate serve to interlock the members together, prevent slipping, and distribute the strains throughout the structure. It is obvious that each of the keys also add greatly to the stiffness of the sheet longitudinally and that each key may in itself be considered as a compression member for strains applied on the same side of the sheet and as a tension member for strains applied on the other.

Should it be desired to make a wall or partition impervious to water or moisture, the sheets, such as illustrated in Figs. 4 and 5, may be used and the wire net clipped thereto, but Without perforating the same, or, if preferred, the net may be soldered thereto, as indicated at b in Fig. 4. Adjacent sheets at the points when the same overlap may be soldered together, or, if preferred, the engaging faces may be covered with pitch, tar, mastic, or other suitable material to render the same impervious to moisture and at the same time cement them together. The cement or other material is then spread on,as before described. This construction is obviously admirable for tunnel construction and provides a tunnellining absolutely impervious to moisture or water.

While the sheet presents a great rigidity longitudinally, the same may be readily bent laterally and may be conveniently used to construct formsor molds to form the outer cas ing for beams or may be bent laterally to form cylindric or other columns, conduits, reservoirs, and other structures.

With the constructions illustrated in Figs. 6 and 7 the reticulated material may or may not be used, as preferred. If not used, the

keys by the flanges, so that the sheet so used may be used as metallic lath are ordinarily used or may of itself be plastered on both sides to form a thin light partition of great strength.

Obviously details of construction may be varied without departing from the principles of this invention.

We claim as our invention- 1. A sheet of metal formed to provide on opposite sides thereof keys projecting beyond its plane, said keys being arranged in rows and the keys in adjacent rows being arranged staggering on the sheet and projecting on opposite sides thereof, meansfor engaging reticulated material on one or both sides of the sheet and a sheet of reticulated material engaged thereon.

2. Asheet of the class described having parallel rows of keys arranged diagonally and projecting on opposite sides thereof, a sheet of reticulated material engaged thereon and rigidly secured thereto and plaster, cement or the like spread on said reticulated material and filling said keys.

3. As an article of manufacture, a sheet having longitudinal depressions formed therein constituting keys projecting alternately on opposite sides of the sheet and forming abrupt angles at the sides and ends therewith, said keys being similarly arranged to adapt the sheet to nest.

4. A sheet for the purpose specified comprising symmetrically-arranged keys formed to interlock with the keys of an adjacent sheet projecting alternately on opposite sides of the sheet and flanges on each side of each key.

5. An article of manufacture, a sheet of metal having formed therein a plurality of sym metrically-arranged keys extending alternately on opposite sides of the sheet and longitudinally thereof, a flange formed as a part of each key and projecting inwardly, and a flange on each side of each key.

6. In a construction of the class described, a plurality of sheets of metal each provided with elongated keys stamped or rolled therein symmetrically arranged, those of one sheet adapted to interflt with those of another adjacent to the ends, and the joint closed with material impervious to water and acting to render the same waterproof and means for rigidly securing overlapped ends of the sheet together when in position.

7. In a device of the class described, a plurality of sheets of metal on which are provided keys extending on opposite sides thereof, means for securing the ends of the sheets together, reticulated material on one or both of the sides of said sheets, clips rigidly engaging said reticulated material to the keys and a compression member of plaster or the like spread on the structure thus formed and filling the keys.

8. In a device of the class described, the combination with a metallic sheet, of integral keys arranged in longitudinal alinement, the

thereof outwardlyextending keys integral therewith, reticulated material engaged against said keys on each side of the sheet,

metallic clips engaging said reticulated material on the keys.

In testimony whereof we have hereunto subscribed our names in the presence of two 15 subscribing witnesses.
