UNITED STATES PATENT, OFFICE.

ANDREW J'. CONNELL, OF COLLEGE POINT, NEW YORK, ASSIGNOR TO EMPIRE ART METAL CO., INC., A CORPORATION OF NEW YORK.

DOOR AND LIKE METALLIC STRUCTURE.

Application filed January 13, 1914.

To all whom it may concern Be it known that I, ANnnnw J. (oxxsnn a citizen of the United States, and a restdent of College Point, New York, have invented certain new and useful Improvements. in Doors and like -Metallic Structures, of which the following is a specificati on.

This invention relates to improvements in number of press operations to place such parts in condition to be assembled, which assembling of parts may be done with great easeand rapidity and may be readily accomplished by unskilled labor: will have greater strength and rigidity when assembled than any structure heretofore made of like material and'weight; the :butting por tions of the parts may be readily and quickly welded and all the seams will be in condition to permit the ready and quick sealing thereof by welding.

In the preferred el'nbodiment of my invention illustrated in the :n-companying drawings, each stile or rail member is formed of two parallel spaced side plates of sheet metal, the opposing longitudinal edges of such plates, where such edges contact with the edges of an abutting member. being provided with inwardly-extemling flanges bent at right angles to the side plates, and the contacting edges of abutting members, such as the molding panel brackets and the transverse edges of the top, bottom and intermediate rails, are formed with a slot extending in the same direction as the aforesaid flanges on the longitudinal edges of the stiles and rails, which slot is of substantially the same conformation as the flange and fits snugly over the same so as to form a seat therefor and such abutting members are also preferably provided with a vertically extending portion adapted to abut against the inner sides of the stile or rail members and anotherportion extending inwardly at right angles to the aforesaid vertical portion, whereby a seat is provided by means of the imvardly-extending flanges on opposite sides for a channel bracing bar, which bracing bar spans the space between the side plates of the stile or rail member and abuts at opposite edges against the bot- Specification of Letters Patent.

Patented Oct. 31, 1916 Serial No. 811,784.

tom side of said slot and the abutting portion integral therewith so as to form a rectangular brace for the opposite sides of the stiles. the inwaidly-extending flanges serving to retain such channel bars in position preparatory to the welding of the same in place.

In the accompanying drawings, in which similar reference characters designate corresponding parts throughout the several views. Figure l is a side elevation of a door embodying my invention; Fig. '2 is a section on the line -2 of Fig. 1: Fig. 3 is a section on the line 3*?) of Fig. 1; Fig. 4 is a section on the line -l. r of Fig. 1; Fig. 5 is a section on'the line 55 of Fig. 1; Fig. 6 is a section on the line (i-6 of Fig. 1, showing the preferred method of closing the ends of the stile members: Figs. 7. 8 and 9 are respectively perspective views of portions of the molding member. channel bar and stile bar before the same are assembled: Fig. 10 is a sectional view of a modified form of door embodying my invention; and Fig. 11 is another sectional view of another modilied form of door embodying my invention.

Referring now to l igs. 1. to 9 inclusive of these drawings which for the purposes of illustration only. show my invention applied to a door. though it adapted for use in metallic partitions and other metallic structures 1 and 2 indicate the stiles of a door, 3

preferably formed with integral edge plates 11 and open. at one longitudinal edge so as to be substantially U-shaped in cross-section, as illustrated in Figs. 2, 3. 5, and 7 t0 9. The center rail or rails comprise similar parallel arranged side plates 9 and 10, open at both longitudinal edges as illustrated in Fig. 4. Each of the parallel spaced plates of the stiles and top and bottom rails are provided along one longitudinal edge with flanges -10 extending inwardly from such plates at right angles thereto, and the center rail is likewise provided at both longitudinal edgeswith similar flanges 9-I0. The panel brackets 6 are formed with the usual panel seats intermediate their edges and BEST AV COP:

contiguous to the longitudinal edges of the panel brackets 6 and also contiguous to the transverse edges of the top. bottom and center rails 3. 1 and 5 respectively. the metal is bent to form grooves 151-'i which form seats for the opposing inwardly extending flanges l 10 respectively. The extreme edges of suchme'mbers 'are preferably bent ,to form L-shaped portions 16 and 17, the

i/ei'iicii'l legs 1617" of such L-shaped porarias abutting against the opposing parallel arranged side-plates and the other legs 16"-l7 extending inwardly therefrom at right angles thereto. The two oppositely disposed L-shaped portions form a seat for a bracing or bridging channel 18, the

longer than the finished height of the door or other structure and are bent inwardly to close theends of such stiles as illustrated in Fig. l; the two parts being then acetylene welded to close the seam, aim I also preferably acetylene weld scams betwcen'tl'ic flanges 9-1 and the grooved portions 15-45", thus forming a seamless door.

Obviously this door may be readily asseiiibled by simply slipping the channel bars 18 in place within their seats along the longitudinal edges of the panel brackets abutting the top. bottom and center rails. which rails may be then readily applied by separating the flanges a suflicient distance to spring into the slots l5-1?i", whereupon the same may be electrically welded in place. The stiles may be then applied in a similar manner and the chai-inels slid in place before closing upthc ends as above described, whereupon the stiles may be spot welded through the vertical legs 16"17 of the L-shapcd portion 16 and the flanges 1818" of the bracing channel 18, after which the ends are closed and the seams scaled as above described.

"In Figs. 10 and 11 I have illustrated slightly modified forms of my invention, Fig. 10 illustrating an L-shaped marginal flange having one leg extending downwardly and Fig. 11 illustrating similar L- shaped flanges with one leg extending upwardly, in each case/the groove in the abutting member conforming to the shape of the flange. In other respects the construction is similar to that above described. In assembling the structures illustrated in Figs.

10 and 11, however, it will be necessary to slide the various parts together. instead of simply separating the flanges and perinitting the sameto spring within the slots as above described.

Having described my invention I claim:
