To all whom it may concern.-

Be it known that I, LONGLEY LEWIS SA- GENDORPH, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented certain new and usefullmprovements in Metallic Ceiling-llates, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

The primary object of my invention is to construct or form the corners of metallic ceiling plates, having raised marginal borders or moldings, in such a manner as to obviate the necessity of cutting away the metal at said corners, as is now commonly done.

In the drawingsz-Figure 1, is a plan view of a portion of a ceiling constructed according to and embodying my invention, illustrating one of my improved plates in an operative position with corner rosettes in position thereon. Fig. 2, is a plan View of one corner of the plate shown in Fig. 1. Fig. 3 is a View similar to Fig. 2, with an adjacent plate in position thereon; and, Fig. 4, is a.

sectional view on the dotted line l, 4, of Fig. 3.

In the accompanying drawings, A, represents one of my improved ceiling plates, having a continuous raised marginal border or molding a, said moldings extending beyond their point of intersection, as shown, forming the projecting portions a at the corners of the plate. I also preferably employ an inner continuous raised bead or corrugation 1?, near the marginal raised portion a, in order to add strength and rigidity to the plate to prevent buckling of the latter.

In placing the plates to position on the ceiling, the projecting portions a will overlap the two marginal beads a on adjacent plates, as shown in Fig. 3, the corners thus formed being covered with rosettes D, each of which is provided with arms (1 of a circular outline in cross-section, the latter fitting over the moldings a, and also over the two projections a on the top plate, as shown by dotted lines in Fig. 1. The rosettes are retained to place by a single nail driven through each of them and through the overlapped portions of the moldings a, at their intersecting points.

One of the prime advantages attained by my invention is, that the uniform rigidity afforded by the raised marginal bead or molding is retained, and the plate rendered. uniform throughout, which points of advantage are destroyed by cutting away the metal at the corners, as is now commonly done. The corner projections a when the overlapping plates are secured together, have a tendency to strengthen the ceiling at those points and where most needed; they also assist to prevent the plates from warping out of position when placed together on a ceiling, in the manner aforestated. The edge of each overlapping plate terminates between the two two beads to and Z), and the latter, when decorated, have a tendency to detract the eye from said terminal edge, thus producing a ceiling that is at once attractive and cheap of manufacture.

What I claim as new and desire to secure by Letters Patent, is:

1; A metallic plate having a raised margin or molding on each side thereof, said moldiugs at the corners extending out beyond the margin of the plate, substantially as set forth.

2. A metallic plate having a continuous raised molding at around its margin, said moldings extending out beyond their intersecting points, substantially as specified.

3. A metallic plate having a continuous marginal moldinga, on each side thereof, and an inner continuous raised bead 1) adjacent to said molding; the latter extending out beyond their points of intersection, forming projections a as and for the purposes set forth.

4:. A metallic ceiling composed of plates, each of which having a raised marginal molding a at each side thereof, said moldings extending out beyond their intersecting points forming projections M, which latter are adapted to overlap a pprtion of the molding on adjacent plates, and a suitable rosette f each corner thus formed, substantially as set forth.

I rosette D having lateral arms (1 overlapping lo the corner moldings and their projections (1 and properly secured thereto, substantially LONGLEY LEWIS SAGENDORIH.
