METALLIC CEILING.

SPECIFICATION forming part of Letters Patent No. 424,319, dated March 25, 1890.

Application filed June 13, 1889- Serial No. 314,166- '(No model.)

s which the following is a clear and exact description, reference being had to the accompanying drawings, forming a part thereof.

This invention relates to improvements in metallic ceilings, and more particularly to brackets for the cornices in such ceilings, and has for its objects to provide abracket which may be constructed from sheet metal, so as to be rigid in form,- light in weight, and easy of manipulation.

In the drawings, Figure 1 is a front elevation of a section of a cornice provided with this improved bracket. Fig. 2 is a longitudinal section of the same. Fig. 3 is a crosssection of the same cut on the line a: m. Fig. 4 is a perspective view of the bracket, the parts being separated to show their separate constructions. Fig. .5 is an end view in perspective of one of the cornice-pieces, showing how it is cut away at the top to accommodate the brackets. Fig. 6 is a front view of an alternative construction of the bracket. Fig. 7 is a cr0ss-section of the same, takenon the line y 3 v The letter A designates the skeleton or inner part of the bracket. In the face it is, provided with projected rib A, which may be of any shape desired.

The letter B designates the lookout or shield. This lookout is formed to substantially the same lines as the skeleton A, and is provided with a rib B, corresponding to the rib A on the skeleton. Along the edges it is further provided with the ribs B for ornamentation and additional rigidity. The projection of the rib A on the skeleton A is slightly greater than the projection of the rib B on the lookout B. In this way is insured a small space between the skeleton and lookout on either side of the said ribs, as shown at Fig. 3 of the drawings. When placed tocure the skeleton and lookout together the lapping portion of the end B is turned over the end A and the strips 13 over the end A as shown in Fig. 2; In this way the skeleton and lookout are securely fastened, as the engaged ribs prevent any lateral displacement and the lapped portions any separation. The

cornice pieces O to which this bracket is applied are provided at the upper edge with the hooked edge 0, which is provided to receive the edge of a styling or the panels of which the ceiling is composed. The lookout edgeis cut away at the ends, as shown in 5, to allow the ends to extend into the space between the lookout and skeleton of the brackets.

In suspending a cornice provided with this bracket the bracket is placed in position on the exposed end of the last piece of cornice by inserting the end in the space between the lookout and skeleton. The end of the next cornice-piece is then inserted in the space in the bracket from the other side. As the cornice is placed in position, it is secured by fastenings driven through the extensions 0 and C, the former of which rests against the side walls of the building and the latter against the ceiling or a strip of wood provided to receive it. As the cornice-pieces are thus secured, the brackets are held rigidly in position without theneeclof independent fastenings. WVhen the cornice is thus suspended, the meeting ends of the cornice pieces are held in shape and concealed to leave no joints exposed. Further, room for expansion and contraction in the cornice pieces is allowed for in the space between the lookouts and skeletons. By thus constructing the brackets lightness and rigidity are at once attained, while the work is attended with greater rapidity and ease.

In the form shown in Figs. 6 and 7, I dispense with the ribbing A and B, and secure the skeleton A and lookout B together by the rivets D. This form I find desirable as being 5 less costly, as I may turn them out with a cornice brake with little expense, while the form shown in Fig. at has to be stamped. In all other respects than that referred to the two forms are the same.
