SPECIFICATION forming part of Letters Patent No. 689,081, `dated December 1'7, 1901.

Application filed July 2, 1901. Serial No. 68.840. (No model.)

To aZZ whom it may concern.-

Be it known. that I, EYVIND LEE HEIDEN- REICH, a resident of Chicago, in the county of Oook, State of Illinois, have invented certain new and useful Improvements in Fireproof Roofs, dac., of which the following is a full, clear, and exact description.

This invention has for its object more particularly to provide an improved construction of plate whereby roofs, ceilings, dac., may be formed; and the invention consists in the features of improvement hereinafter described, illustratedin the accompanying drawings,and more particularly pointed out in the claims at the end of this specification.

Figure lis a view in vertical section through a roof embodying my invention. Fig. 2 is a view in crosssection online 2 2 of Fig. l. Fig. 3 is an enlarged detail view in cross-section, showing the abutting ends of two roof-plates interlocked with a supporting-beam. Fig. et is a detail perspective View of one of my improved roof-plates. Fig. 5 is a view showing one edge of the improved roof-plate. Fig. 6 is an enlarged detail view showing the manner of connecting the sides of the roof-plates together. Fig. 7 is a detail view of one of the ridge-plates.

A designates the I-beams of the roof, which may be arranged in usual or suitable Inanner. Across these I-beams extend channelbeams B, that are secured to the I-beams and are preferably U-shaped incross-section, as shown. My improved construction of roofplate will rest upon the channel-beams and will be interlocked therewith, as will presently more fully appear. In the preferred form of the invention the plates that cornprise the body of the roof are of substantially the shape and construction shown in the drawings-that is to say, each of these plates C has one of its ends formed with a reverted edge c, adapted to engage the flange of one of the channel-beams B, as clearly shown in Figs. l and 3 of the drawings. This end of the plate C is preferably beveled, as at c, above the reverted end c, so as to receive the correspondingly-beveled end c2 of the adjoining plate. Each of the main plates being thus formed with a reverted end and with its opposite end beveled, .the plates can be interlocked with the supporting-beams and can be engages the reverted end c of the plate.

set together, as clearly shown in Figs. l and 3 of the dra-wings.

In order to enable the plates C to be securely joined or interlocked, each of these plates is formed with offset flanges c3 and ciL at one of its edges, these iianges c3 and c4 forming between them a channel adapted to receive the plane edge c5 of the next adjoining plate. (See Figs. 2 and 6.) The flange c3 upon the under side of each plate is cutaway at its ends, as seen in Fig'. 3, in order to permit the plates to be set in position upon the beams. Thus by reference to Fig. 3 it will be seen that in order to permit the reverted edge c to be hooked over the upper flange o of the channel-beam B the end of the plate-Hangs c3 must be first brought close to the back of the channel-beam and will then be drawn away therefrom as the flange b of the beam In placing the plates in position a layer of cement CZ will preferably be interposed between the anges b of the channel-beams and the engaging ends c of the plates. So,also,a layer of' cement or mortar cl will be placed between the beveled portion c of the plate and the correspondingly-beveled portion c2 of the adjacent plate. A layer of cement or mortar d2 will also be placed in the joint between the lianges c3 and c4 of the plates and the edge c5 of the adjoining plates, that are received between these flanges. From this construction it will be seen that each of the roof-plates will be securely locked to the cross-beams or channel-beams, and the plates of each row will have their side edges firmly locked together.

In Fig. l of the drawings is shown the preferred manner of forming the ridge of the roof. This ridge will consist of angular ridge-plates E, each of which will bemolded with the ribs e, adapted to t over the transverse ribs c6, that will be formed adjacent the upper end of such of the plates O as will be located immediately next to the ridge of the roof. At the ends the ridge-platesE will be formed with the iianges e2 and e3, forming a channel to receive the edge of the adjoining ridge-plate, and each of the ridge-plates will preferably be provided with a metal stay- -frame consisting of intersecting wires, this stay-frame extending into one of the [ianges at the end of the ridge-plate.

IOO

In practicing the invention the plates C Will preferably be molded of mortar or like plastic material, and in the process of molding the plates there Will be embedded in each of the plates a metal stay-frame that consists, preferably, of transversely-disposed Wires f and f. By reference to Figs. l and 8 it Will be seen that these wires are molded in the reverted ends c of each plate, thereby giving great strength thereto and-enabling the plate to securely engage the supporting channelbeam beneath it. It will also be seen that each of the metal stay-frames is extended into the beveled end c2 of each plate, thereby greatly enhancing the strength of such portion of the plate. The feature of forming plates from plastic material havingstay-wires embedded therein is not novel; but I believe my present invention presents the first instance of a plate formed from plastic material and having a reverted end, suitable metal stays being embedded in said plate and in said reverted end portion. The terms reverted end and reverted edges as herein employed are not intended to limit the invention to the precise details set forth, since manifestly the extent to which the ends or edges are turned inwardly or reverted from the body of the plates is not essential.

One great advantage incident to the construction above described is that the plates being formed in section can be made at a distance from the Work (and hence under cover and in any kind of Weather) and can be quickly set in place with but very little trouble and expense. l A roof embodying this invention will be found particularly advantageous for factories, rolling-mills, steel-mills, and the like, Where the gases incident to the Work being done would ordinarily tend to speedily destroy the corrugated-iron roofs commonly employed in such situations.

Vhile the improved plates above described are more particularly intended for use in the construction of roofs, it is manifest that such plates may also be advantageously used in forming ceilings, partitions, or like parts of iireproof structures. The ridge-plates E may be used for gutters and will be found particularly applicable Where gutters are interposed between the eaves of twoladjoining roofs. In such case the ridge plates E will simply be inverted. It Willbe readily understood that Where special shapes are required for conductors, gutters, &c., these may be easily molded and placed in position.`

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. Aplate for roofs, dac., formed from plastic material and provided at one end with an angularly-extending or offset portion adapted to engage a supporting-beam and a metal frame or stay embedded in said plate and in said angular or offset portion that engages said supporting-beam.

2. A plate for roofs, &c., formed from plastic'material and having a reverted edge, said plate having embedded therein a metal stayframe extending around said reverted edge.

3. A plate for roofs, dac., formed from plastic material and having a reverted edge With a beveled upper surface.

4. A plate for roofs, dac., formed from plastic material having one edge reverted and beveled upon one side, the opposite end of said plate having its edge oppositely beveled.

5. A plate for roofs, dac., having one of its edges beveled and reverted and having its opposite edge beveled and metal stays extending around said reverted edge and into said opposite beveled edge.

6. Aplate for roofs, dac., formed from plastic material and provided at one end with an angularly-extending or offset portion adapted to engage a supporting-beam and having its edges cut away to engage the edges of the adjoining roof-plates and a metal frame`or stay embedded in said plate and in said angular or oset portion.

7. A iireproof structure comprising metal supporting-beams and bars and plates formed of plastic material having angularly-extending or offset portions adapted to engage said supporting bars, said plates having their edges cut away to receive the edges of adjoining plates and metal stays or frames embedded in said plates and extending into their angular or offset portions and into their cutaway edges.

8. A roof for fireproof structures comprising metal supporting-beams and bars and plates of plastic material, said plates having theiroverlapping ends arranged opposite said supporting-bars and having angular or offset portions adapted to engage said supportingbars, and metal frames or stays embedded in said plates and in their overlapping ends and angular portions.

9. Aplate for roofs, dto., formed from plastic material having oppositely-oset flanges at one of its edges to form a channel to receive the edge of the adjoining plate, and metal staysl embedded in said plate and extending-into one of said offset iianges.

10. A plate for roofs, dto., formed from plastic material having one edge provided With oifset ilanges forming a channel at said edge to receive the edge of the adjoining plate, one of said edge flanges being shorter than the body of the plate to permit the interlocking of said reverted edge of the plate with the sustaining-beam.

Il. A roof for fireproof structures, compris-` ing metal beams and cross beams or bars and roof-plates formed of plastic material having inwardly-turned edges to interlock with said cross beams or bars, said plates being provided with suitable metal stays and the edges of the plates being interlocked together.
