.Specification of Letters Patent. P t t d Ma 3, 19 21.
Original application filed June 30,1919, Serial No. 307,514. Divided and this application filed November 18, 1919, Serial No. 338,904. Renewed March 19, 1921. Serial No. 453,710.
T all ham it may concern 7 citizen of the United States of America,
residing in the city of Pittsburgh, county of Allegheny, and State of Pennsylvania, have invented or discovered a new and Improved Cross Furring-Strip, of which the 7 following is a specification. v
This patent application is a' division of my pending patent application filed in the United States Patent Office, Serial Number 307,514, filed June 30th, 1919.
My present invention consists in a new and improved cross furring strip for steel ceilings.
More particularly, my cross furring strips are designed for the support of the lateral edges of adjacent ceiling plates between main furring strips, and consist of a length of metal bent to form a vertical web adapted to be interposed between the flanged edges of the ceiling plates, a pair of laterally extending shoulders at the top of said web against the underside of which the ceiling plates bear, and a pair of laterally extending flanges at the bottom of said web upon which the flanged edges of the ceiling plates rest and which are clenched up against said flanged edges to clamp the celling plates firmly in position. I also prefer to provide an upwardly extending top web to strengthen the strip, and I preferably flange said top web to add to the strength of the strip.
In the accompanying drawings, Figure 1 is an inverted plan view of a section of steel ceiling to which my present invention is applied; Fig. 2 is an enlarged and inverted section taken along the line II-II in Fig. 1, showing a main furring strip and two cross furrlng strips supporting two celling plates, the flanges of said strips being unclenched; Fig. 3 is a similar view showing the flanges clenched; Fig. 4 is an inverted and enlarged section taken along the line IVIV in Fig. 1, showing a furring strip supporting two ceiling plates, the flanges being unclenched; Fig. 5 is a similar view showing said flanges clenched, and Fig. 6 is a broken perspective of one of my improved cross furring strips.
The following is a detailed description of the drawings.
A represents the'steel ceiling plates of rectangular form and provided with downwardly turned edge flanges l. B represents the main furring strips whose inclosed box bodies 2 are attached to the undersides of the building joist C by means of the nailing flanges 3. 4 is a vertical web depending from the body 2 and providedat its lower end with two laterally extending clenching flanges 5 upon which the flanged edges of the plates A rest, and which flanges 5 are then clenched up against the flanges 1 of the said. plates. i v f The structure of my said main furring strips is more fully set forthfin my above mentioned pending patent application.
The flanged sides or lateral edges of the ceiling plates are supported by my cross furring strips D, formed by bending up a metal strip to provide a top web 6, a pair of laterally extending shoulders 7 at the bottom of said top web. a second web 8, de-
pending from said shoulder, and two laterally extending clenching flanges 9 at the bottom of said second named web. 10 is a horizontal flange on said first mentioned web intended to further strengthen and stiffen the entire strip. The cross furring strips D are of the properlength to extend between adjacent main-furring strips, the
main furring strips supporting the ends of the plates while between said main furring strips, the cross furring strips maintain th plates in proper alinement.
In installing the ceiling, the cross furring strips are placed between. adjacent plates, the web 8 being interposed between the flanged edges of the two plates A, the shoulders 7 resting upon the tops of the plates, while the flanges 1 of the plates A rest upon the flanges 9 of the cross-f-urring strip. The flanges 9 are then clenched up against said flanges 1, and the structure is firmly clamped together, so that the plates cannot become loose or bulge or sag.
The flexibility of the strips assists in putting the cross furring strips in position, as they may be sprung out of shape for the insertion of the ceiling plates along the walls. A steel ceiling constructed in accordance with my invention can be quickly and easily put in place and forms a permanent structure of neat appearance. It thoroughly protects the wooden joist and other inflammable portions of the building, an ample air spacebeing provided above the ceiling plates which insulates the wooden portions that they will not sag or bulge in the presence of great heat, and only a melting temperature will loosen or permanently injure the lates;
hat I desire to claim is n l. A cross furring strip for steel ceilings having a vertical web adapted to be interposed between the flanged edges of adjacent ceiling plates, a pair of lateral shoulders resting on the tops of said plates, a pair of lateral flanges upon which the edges of said plates rest, said flanges being adapted to be clenched upwardly against the flanged edges of said plates to clamp the structure together, and a vertical top web to stiffen said strip.
2. Across furring strip for steel ceilings having a vertical web adapted to beinterposed between the flanged edges of adjacent ceiling plates, a pair of lateral shoulders resting on the tops of said plates, a pair of 'lateral flanges upon which the edges of said together, a vertical top web extending up-' wardly from said shoulders, and an angular stiffening flange at the top of said top web.
A cross furring strip for steel ceilings formed by bending up a metal strip and having a vertical Web adapted to be interposed between the flanged edges'of adjacent ceiling, plates, a pair of lateral shoulders resting on top of said plates, a pair of lateral flanges upon which the edges of said plates rest, said flanges being adapted to be clenched up against 'the flanged edges of said plates, a vertical topweb extending upwardly from said shoulders, and an angular stiffening flange at the top of said top web.
Signed at Pittsburgh, Pa, this 14th day of November, 1919.
