Description

PATENTED AUG. 11, 1908.
J. A. STEVENS.
METAL CEILING.
APPLICATION FILED MAR. 10, 1908.
noemtoz UNITED STATES PATENT OFFICE.
JAMES ALBERT STEVENS, OF NEWBURYPORT, MASSACHUSETTS.
METAL CEILING.
To all whom it may concern:
' Be it known that 1, JAMES ALBERT STE- VENS, a citizen of the United States, residing at Newburyport, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Metal Ceilings, of which the following is a specifi.ca tion.
The present invention relates to metal ceilings, and has specially in view an improvement in the means for causing the overlapping edges of the ceiling plates or panels to interlock so as to insure said plates or panels being retained in a relatively rigid position, said interlocking means being of an ornamental appearance and being so arranged whereby the heads of the fasteners may be utilized to form part of the ornamentation.
With the above and other objects in view, the invention comprises certain features of construction which will be described in detail in the specification, pointed out in the claims, and illustrated in the accompanying drawings.
In said drawings, wherein like characters of reference have been used to designate corresponding partsFigure 1 is a plan view of a portion of a ceiling showing the present invention applied thereto. Fig. 2 is a plan view of one of the plates or panels, the same being shown detached from the ceiling. Fig. 3 is a sectional view taken on the line 3 -3 of Fig. 1. Fig. 4 is a sectional view taken on the line 4-4, Fig. 1.
Referring to said drawings, 10 designates the plates or panels, which are provided adjacent to each edge with a series of regularly spaced-apart fastener holes 1 1, around which are formed a plurality of projecting buttons 12, and between each pair of fastener holes long locking ribs 18 are formed. Said buttons 12 and locking ribs 13 are formed in the overlapping edges of each plate or panel by any suitable machine which will act upon the under side of the plates or panels and force up the material in the desired button and rib shape, and leave in said under side of the plates or panels corresponding button shaped recesses 14and long locking grooves 15.
' To attach the plates or panels to a ceiling a fastener 16 is used, which is preferably a screw provided with an oval shaped head 17 Specification of Letters Patent.
Application filed March 16, 1908.
Patented Aug. 1 1, 1908.
Serial No. 421,286.
In attaching the plates to the ceiling, the first plate is securely fastened thereto by means of the fasteners. The next plate then has its edge placed over the edge of the first plate and pressure is applied thereto to force the buttons 12 and ribs 13 into their corresponding recesses 14 and grooves 15. This causes the said plates to interlock, after which the fasteners 16 are passed through the registering fastener holes 11 and into the timber of the ceiling.
By referring to Fig. 1 of the drawing it will be observed that the arrangement of the buttons 12 relatively to the fastener hole 11 is such that when the plates are in position on the ceiling, the buttons around the said hole are so positioned that the button or buttons appearing on the overlapped plate completes the series surrounding said hole, Which unite in forming, when the fastener is in position, an ornament thecenter of which is the orna mental head of the fastener, thereby imparting tothe plates the appearance of having rosettes or similar ornamental and supplemental attachments, which ornamental apearance is further augmented by the long ocking ribs which are arranged between each pair of fastener holes.
While I have shown and described the fastener as a screw provided with an oval head, it will of course be understood that the inven tion is not necessarily limited thereto, for it will be obvious that other kinds of fasteners may be used.
Claims:
In a metal ceiling, the metal ceiling plates having fastener holes, long hollow ribs, and a group of hollow buttons arranged adjacent to each end of said ribs and around said holes, said ribs and buttons being formed in each plate adjacent to the edges thereof and adapted to interlock when the edges of each plate are placed in an overlapping position, and oval headed fasteners passed through said fastener holes.
In testimony whereof I hereunto affix my signature in the presence of two witnesses.
J. ALBERT STEVENS.
