PETER EBNER, OF COLUMBUS, OHIO.

METALLIC CEILING OR SHEATHING.

To all whom it may concern:

Be it known that I, PETER EBNER, aI citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Metallic Ceilings or Sheathings, of which the following is a specification.

My invention relates to metallic ceiling or sheathing, the object of the invention being to provide improved locking means for locking the panels, comprising the ceiling,

into engagement with each other and to so construct and arrange said locking means that the connection between the panels may be readily made either before or after the panels are united with the furring strips or supporting framework.

A further object of the invention is to provide a frictional locking means between the panels, the member of one panel being engaged with the member of the opposed panel by an upward movement in contradistinction to the devices sometimes employed and in which the engagement of the panels with each other is brought about by a lateral movement of one of said panels.

Further objects and advantages of the invention will be set forth in the detailed description which now follows.

In the accompanying drawing: Figure l is an underside view of four ceiling panels constructed in accordance with the invention; Fig. 2 is an enlarged sectional view of the device; Fig. 3 is an underside view of the outer portion of one of the ceiling panels; Fig. 4E is a sectional view illustrating the method of connecting adjacent edges of the panels to furring strips hereinafter described.

Like numerals designate corresponding parts in all of the figures of the drawings.

Referring to the drawing the numerals 5 designate sheet metalpanels of that character designed to be used in the construction of sheet metal ceilings or side walls, these panels being cut or stamped to the required size and suitably embossed or ornamented as desired. In the construction of each of the panels 5, one side thereof is bent rearwardly or upwardly to form an edge tongue or flangel 6 which in its outer portion is curved inwardly and then outwardly as at 7 to render the tongue resilient by reason of such curvature. The opposite edge of each of the pan- Specfcation of Letters Patent.

Application led April 15, 1908.

Serial No. 427,182.

els, with the exception of those panels which lie adjacent to the sides of the room, is formed with an upwardly projecting portion which is bent downwardly upon itself to form a loop 8. This loop likewise is to some extent resilient and is of such width at its lower or neck portion as to present a comparatively narrow entrance. In the joining of two adjacent panels the curved tongue 6 of one panel is forced through the narrow entrance of the loop of the adjacent panel thereby springing the outer member of the loop slightly outward and causing the outer edge portion of the tongue to engage the inner surface of the loop and to lie in the upper portion of the latter. rl`his engagement in conjunction with the pressure on the tongue of the outer member of the loop serves to form a desirable detachable locking connection of adjoining panels which can be produced either before the panels are placed in position against the ceiling framework or afterward.

It will be understood that the above described method of connecting the panels may be carried out through one row of panels at a time and that the adjoining rows of panels when similarly united are connected with the first mentioned row by causing their adjacent edges to overlap each other in the manner indicated in Fig. 4, said overlapping portions being suitably nailed to the furring strips 3 which are secured at proper intervals to the ceiling framework. It will be observed by referring to Fig. 3 that the loop 8 is not of such length as to extend to the ends of the panel (which is also true of the tongue 6), thus providing a space between the ends of the loops and tongues of two adjoining panels for the free passage of the furring strips.

From the foregoing description it will be seen that simple and efficient means are herein provided for accomplishing the objects of the invention, but while the elements shown and described are well adapted to serve the purposes for which they are intended it is to be understood that the invention is not limited to the precise construction set forth, but includes within its purview such changes as may be made within the scope of the appended claims.

Having thus described my invention what I claim is:

1. In a metallic ceiling or sheathing construction, a sheet metal panel comprising a substantially horizontal body portion heving one of its edges formed With an upturned curved tongue portion and its opposing edge formed With e loop projection into which the tongue projection of an adjoin-v ing panel is adapted to he inserted and held loy friction-al engagement of the parts7 the loop projection having zt reduced neck portion adapted to engage the curved tongue portion.

2. In a metallic ceiling or sheathing construction, a sheet metal panel comprising a substantially horizontal body portion having one of its edges formed with an upturned curved tongue portion and its opposing edge formed with a loop projection into which the' tongue projection of an adjoining panel is adapted to be inserted and held by frictional engagement of the parts, the loop projection having'st reduced neck portion adapted to engage the curved tongue portion, said tongue and loop portions being of lengths edges. y

ln testimony whereof I aiiix my signature in presence of two Witnesses.

PETER EBNER.
