SHEET-METAL CONSTRUCTION.

Specification of Letters Patent.

Patented Apr. 4, 1911.

Application filed August 29, 1910. Serial No. 579,530.

citizen of the United States, and resident of'Jamestown, in the count-y of Chautauqua and State of New York, have invented new and useful Improvements in Sheet-Metal Construction, of which the following, taken in. connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to sheet metal doors and windows; and the object of my improvement is to provide a strong sheet metal construction by means of which doors and windows may be quickly and easily made and assembled without the need of rivets or bolts for holding the stiles, rails, panels or glass and molding together; and the invention consists in the construction and arrangement of the parts as described in this specification and shown in the accompanying drawings and pointed out in the claims.

In the-drawings, Figurel is an elevation of a sheet metal door. Fig. 2 is a perspective view .of a portion of the door, the molding and one of the panels being removed to show the construction of the parts. Fig. 3 is a crosswise sectional view of the mold ing and stile or cross rail showing a modification of the preferred form for holding the molding in place; and Fig. 4 is a perspective View of a single piece of the stile or cross rail showing the modification set forth in Fig. 3 for holding the molding in place. Fig. 5 is a perspective View of'a portion ofthe stile or cross rail showing another modification of the holding means for the molding. Fig. 6 is a len thwise sectional view of the door at line i X in Fig. 1 showing the construction and arrangement of the parts in a door having a glass panel. Fig. 7 is a pers ective view of a portion of the door, the e ge being shown in section.

door at line Y Y- in Fig. 1. 'Fig. 9 is a crosswise sectional view at line Z Z in Fig. 1, showing the manner of attaching a sheet metal panel to the stiles in an all sheet metal door; and Fig. 10 is a similar view showing-the manner of attaching a sheet metal panel to the stiles in a door having a glass upper-panel; and Fig. 11 is a similar view showing the manner of attaching the molding to the stiles and thereby holding the glass anel. Fig. 12 is a perspective view of a piece of the molding. I Fig. 13 is a per- Similar numerals refer to corresponding parts in the several views.

The numeral 10 indicates the stiles which are each made out of a single sheet metal plate bent in tubular form with the lengthwise ed es brought together inthe double lengthwise central flange 11 on the inner edge. The sides 12 of the tubular stile adjacent the flanges 11 are given an acute angle to the said flan e so as to project the sides into tubular stile 10, the two sides forming a V-shaped angle.

The

rails

13, 14 and 15 have their ends formed at a corresponding outward angle, as shown in Fig. 8, to fit within the angle of sides 12 and flange 11, the opposite ends of the rails forming a dove-tail shaped joint with the stiles. An inturned flange 16 is provided on each end of the rail to hold against flange 11. The rail ends are preferably spot welded on to side12. When the rail is slipped into place, .the dovetail shaped joint braces all parts firmly and the spot welding holds the rails from slippin sidewise, thereby making a very strong an rigid construction. The inner sides of

cross rails

13 and 15 and both sides of the middle cross rail 14 are formed at the inturned or V-shaped angles 12, the same as the stile and also as to the double flange 11. The middle cross rail 14 is made in two pieces which are preferably joined together by spot welding, after being slipped into place within the stiles 10. It is apparent that

rails

13 and 15 may be made in either one or two pieces.

In an all sheet metal door the edges of the panels 17 fit closely within'the acute angle formed by sides 12 and flange 11 on the stiles and cross rails. This is sufficient to hold the panels quite firmly in place, but they may also be spot welded if desired. In a door having an upper glass panel 18, the lower sheet metal panel 19 is formed with a shoulder 20 along ,each side, so that each edge of flange 11 abuts against a shoulder 20, and the contacting edges 21 of the panel 19 extend through between the double flanged edges 11. This arrangement of the lower panel and stiles and cross rails permits the holding of the glass panel 18 in practically the sa 1])0 way. The edges of each part i of the double flange 11 al'mtf'lng against the cross rail. The side of the molding adjacent the panel 19 or flange 11 is formed with a lengthwise slot 25. Molding 22 is securely attached contiguous to the stile or cross rail by means of a lug or offset 26 which is struck from the flange 11 or the panel 19 according to the two forms of construction used, as shown in Figs. 9 and 10. Offset 26 is preferably made with the two pairs of notches 27 on opposite sides through which the edges of the molding 22 adjacent slot 25 are slipped, as shown in Fig. 10 and in the sectional views. A sufficient number of offsets 26 are provided to hold the molding in place on each side of the panel, usually two to each side. The parts are preferably made so as to fit tightly and the spring of the sheet metal holds them all firmly in place. The angular side 12 holds the molding so that it can not be displaced on the offsets 26, and the molding braces all the parts rendering them exceedingly rigid and strong.

In the modifications shown in Figs. 3 and 4 the panel 19 is made straight and yet passes within the flanged edge 28 of the stile or cross rail. The offset flanged edge 28 has the lugs 29 turned back therefrom so as to form a holding means in both directions for the slotted molding 22. This modified form of attachment for the molding 22 may be used in certain forms of doors, but is not applicable to all forms. i k A simple modification of offset 26 is shown at 33 in Fig. 5 and itsapplication would seem to be obvious.

In assembling the door the two stiles 10 are placed a spaced distance apart corresponding to the length of the rails. The parts of the middle rail 14 are then slipped into place and attached to the stiles and to one another. The panels on the opposite sides are then inserted. The molding is then slipped endwise into place on oflsets 26, after which the top and bottom cross rails are attached, channel irons 30 being. provided in thecross rails. When the glass panel 18 is inserted, the upper edge of the top cross rail 15 is left open for the insertion of the glass panel and is closed by means of achannel iron 30 and a strip 31 is attached thereto by means of suitable screws. The channel iron 30 for the upper edge of the top cable to sheet metal windows.

cross rail. 15 is preferably formed with a longtlmisc slot 32 therein, as shown in Fig. 7. This arrangement allows of the removal of the. glass after the assen'iblage of the door. and the insertion of new glass, it only being necessary to remove the top plate 31, after which theglass may be inserted through slot 32.

It is obvious that the construction around glass 18 shown in Figs. 7 and 11, is applirails and stiles around glass 18 show a simple frame construction applicable to sheet metal windows and the slotted molding and offsets form a strong and convenient method of holding the glass.

It is apparent that the exterior and interior angles of the sheet metal in the stiles are substantially equal. that the offsets for receiving the slotted molding have extensions in opposite directions so that the molding is held on the inner sides adjacent the slot, which slot is placed adjacent the angled sheet metal.

I claim as new:

1. In sheet metal construction, a sheet of metal having substantially equal exterior The cross It is also obviousand interior angles, offsets on said sheet of metal near said angles having extensions in opposite directions, and tubular molding having a slot therein in order that said molding may slide under said extension.
