WILLIAM R. KIN-NEAR, OF COLUMBUS, OHIO.

METALLIC CEILING.

SPECIFICATION forming part of Letters Patent No. 443,324, dated December 23, 1890.

Application filed April 28, 1890 Serial No. 349,853. (No model.)

To to whom it may concern.-

Be it known that 1, WILLIAM R. KINNEAR, a citizen of the United States, and a resident of Columbus, in the county of Franklin, State of Ohio, have invented certain new and useful Improvements in Metallic Ceilings; and I do herebydeclare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming apart of this specification, and to the letters of reference marked thereon.

This invention relates to improvements in metallic ceilings; and it consists in the construction and arrangement of the parts hereinafter more fully set forth and described.

In the drawings, Figure 1 is a plan view of a ceiling provided with furring-strips such as I use and partly covered with panels. Fig. 2 is a longitudinal section of two jointed panels on an enlarged scale.

Heretofore when it was desired to place a ceiling on a structure the ceiling-joists were provided with furring-strips, which crossed each other to divide the ceilings into pockets or regular spaces to receive the body of the panels, while the margins of the same rested on the furring-strips. This method of construction has always entailed a great deal of trouble and expense for the reason that in placing the cross furring-strips great care was required to get them in the correct positions to receive the panels. This necessitated the employment of greater time and of more expert labor than would otherwise be required, causing the cost of the completed ceiling to be very much increased over and above what it would he were the necessity for the cross-stripping obviated. It is to obviate these objections that is the object of the present invention. The panels in the constrnction of the body, moldings, and margins are the same as those shown in Letters Patent No. 424, 313, granted to me March 25, 1890, and in the drawings accompanying this application at Fig. 1. To the margin on one side of the panel I attach the loop A,which is formed by folding the metal upon itself, as shown at Fig. 2 of drawings. This loop is made large enough to receive any of the margins on the other sides of the panels, the side B, however, in which the decorations are omitted, is especially designed to enter the loop. To strengthen the construction of the loop, the flange or turned edge A is provided. While in some cases this flange is a very desirable construction, it is not an indispen able feature, as the metal is quite stiff enough in most forms to hold its shape without the aid of this element.

\Vhen the panels herein described are to be used, only the f urring-strips C, running across the ceiling-joists, are used. The panels are then placed in position with the margins 00 0c resting on these strips, to which they are fastened by nails or other suitable fastenings. In this position the margin having the looped end and the margin B are suspended between the strips without support, and the former extending toward the unfinished portion of the work. As the succeedin g panel is placed in position adjacent to the margin provided with the loop A, the margin B of such panel is inserted in the loop and the other margins are adjusted in position on the strips. So on, as each panel is added in the line of the furring-strips C the margin B is inserted in the loop A of the preceding panel. In this construction the margins which are not resting on the furring-st-rips are held firmly in position by the loop A, and the outer edge of the loop and the inner line of the molding of the adjacent panel form but one line, as do the lapped margins on the furring-strips.

lVhat I claim is In a metallic ceiling such as described, the combination of furring-strips to form unbroken channels, panels resting on said strips provided on all sides with margins, upon one of which is formed a groove adapted to re ceive one of the other margins of an adjoining panel, and a stiffening-strip attached to one of the joined margins and extending across the channels formed by the furring' strips, substantially as described, whereby buckling or bending is prevented at this part of the construction.
