METALLIC CEILING.

SPECIFICATION forming part of Letters Patent No. 533,663, dated February 5, 1 895.

Application filed June 4, 1894, Serial No. 518,462. (No model.)

To all whom it may concern.-

Be it known that 1, JAMES OLD, a resident of Allegheny, in the county of Allegheny and State of Pennsylvania,have invented certain 'new and useful Improvements in Metallic Ceilings, and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same. I

The invention relates to metallic ceilings and has forits object to provide metal sheets or plates that can be conveniently joined and secured in place by the aid of separate fastening pieces having a ,bend or hook adapted to embrace the overlapped edges of adjoining plates and it has for its further object to secure such advantage by a construction that can be formed by the ordinary tools of tinners and without waste of material, and that is also adapted to produce certain ornamental combinations; and it consists in the matter hereinafter described and particularly pointed out.

Inthe accompanying drawings Figure 1 is a section of a ceiling secured to a joist. Fig. 2 is a similar view showing interior panels surrounded by rounded ribs in relief. Fig. 8 is a partial plan partlybroken away of a ceiling like that shown in Fig. 1; and Fig. 4 is a similar view of the construction shown in Fig. 2.

Numeral 1 denotes a metal plate having two edges preferably adjoining each other on each side of a corner formed in U shape by bending the same as illustrated at 2. A supporting piece 3 made of a narrow strip of metal having preferably nearly the same length as the plate is also made U-shaped in cross section by bending one edge and is adapted to embrace the U-shaped edge of a plate 1. Said fastening strip supports the edge of the plate along substantially its entire length.

An offset is denoted by 4, and 5 is a lip or flange formed on two edges of the plate not provided with the U-shaped bend.

The onset is so formed that in connection with the part 4: of the bend in the opposite plate a groove is produced. (See Figs. 1 and 3). Similar grooves 4" are stamped or pressed in the body of the plates dividing them into small panels having an ornameu tal effect the whole being adapted to conceal the joints. The ofiset may be variously formed and another example is illustrated in Figs. 2 and 4. In these figures 9 denotes an interior panel surrounded by a head 10, the plate itself being bounded by beads 11 formed in manner similar to that described in connection with Figs. 1 and 3. The plates formed as shown in the several figures are adapted to be variously arranged to produce ornamental effects heretofore attained by forming the ceiling entire. For example the field of a ceiling may be made as in Fig. 3 and the styling or border as in Fig. 4 in which case two plates of unequal length are made to have a united length equal to that of two field plates. The main advantages of my improvement consists however in the readily separable plates which when in position are free to expand or contract and which are for this and other purposes supported by pieces adapted to be formed of waste material and no part requiring the use of any but ordinary tools. 6 denotes joists and 7 furring strips and 8 indicates nails or screws for fastening the metal pieces 3 to the furring strips.

Heretofore the edges of metal ceiling plates have been so bent as to produce in cross section approximately an S-shape the other edges being provided with a simple bend or flange. This form is objectionable for the reason that the S-bend is difficult to form and requires a special and expensive tool. It also involves a waste of material the S-shaped edge being integral with the body of the plate, Whereas by my improved construction the supporting piece indicated by 3 can be made of waste material and both it and the edges l of the snpportingpiece above the U-bend of r the adjoining; plate. One edge or lip 5 is other plate areslippedinto the U-shaped bend fold or U-bend,the bends of the plates and fastening pieces engaging each other, and the lips of adjoining plates being entered in the bend of the fastening pieceabove that of the corresponding plate, substantially as set forth.

pushed into place lengthwise of itself and the adjoining oneis entered at right angles to the i first. I 1 In testimony whereof have signed this Having thus described my invention, What specification in the presence of twosnbscri b- 'I claim isin g Witnesses.

The plates having a single return fold or U-bend on two of its edges and an offsetlip on the other two edges combined with supporting pieces having each a single return Witnesses:
