iseonstruoed of a, single sheet of metal bent, 01" rolled uiou it-self to iroi'ide 0' )0- i i L site ide walls 10, 11, an inner edge well 12, (13111 2111 outer: edge Wall 13, the longitudinal marginal portions of the metal forming said stiles and rails being" connected by an inrails being at one of the corners at their outer edges, while the Seam oi" the intex -maybe, and bending one of: the marginal portions inward, thenflatei'ally toward the nearest slde wall, the other marginal portiOn bein bent inward, thence latei'allV also i b to the nearest-side wall, thence outward in COIlllilCll with sa d side wall and toWui d'the edge well from which it pi'ojeetsland finally laterally in a revereedireetion so as to interloel: with the first-mentioned marginal portion. in this manner the opposite marginal port ons of the sheets forming the st les and rails are hent'liifo revei'eely er-v interlooket one 01: the four" s ngles created each Mile and rail. i i

The l'llllS are placed between the etileeand riveted, weld-ed, oi otherwise fastened thereto and in the opposite longitudinal edges of the intermediatemil, the inziel edges of the uppet and lower mils, and iheinner edges of the stiles;dove-tailed groovee o1? depressions 19 are formed, by bending ihe metal into channeLshape with its side Walls preferably converging oi'itward.

Although we have shown a glazed panel with niezins fOl fastening the panes of glass rude nmllioii between the panes-of glass and also metal-lie panel beneath the glazed panel, and means "for fastening it in place,

it is nppai'ent that metallic panels may be used lilllfi'll qllfllllfitllBdOOl, or :1 single glazed panel ay heiieed if desired, as lliis would require merely the elimination of vermin parts of om invention which can be ie 'ily done, i; perts'of our inwntion can. he need with mivit-lioufliother pin-ts as will. be elmi'ly understood from the following deer tion.

visible seem at one of their four'eorners, the i seams oi. the stiles and the upper mid lower substantially tubular form and has a As hereinbefore stated, the panes of glass 6, constitute a glazed panel; and wherein hereinafter the term panel is used, it is to be understood as a general term covering a metallic or other these panels are fastened to the stiles and rails, We will term the fastenpanel molding e resort for the panel molding used with glazed rately vdesignate each by numerals. panel molding used for holding a pane or panes of lass in place, comprises two members 16, 1 which we shall term, respect vely, a backing molding and a fastening molding. Each length of the backing molding single strip of sheet metal bent or fashioned to provide a bearing wall 8 arranged parallel with the sides of the door, from which wall the strip of metal is bent transversely in: opposite directions, as An oblique wall 22, preferably curved and bent to provide an ornamental surface, extends from the transverse wall 20 edge of the stile Wall 23 which lies in contact with the stile the metal is the edge of the door at an with one side stile, or rail, and thence laterally a short distance in contact with the inner Wall of said depression. From the transverse Wall 21 the metal is continued at an obtuse angle to enter depression in the stile,

or rail, and lie in contact with its other side Wall, and thence depression. The mar inal porseparated the inner somewhat can be pressed toward of easily entering them depression and after relieving them from pressure, permit their separating to impinge against the Walls of said depressions. T e backing molding is Jecting spring portion which fits into the depression of the stiles and rails. A reinforcing bar in the form of a metallic angle bar 24 is placed Within the tubular backing molding to bear against the marginal portions thereof and hold them against inward pressure.

Each length of the fastening molding,

which coacts with the hacking moldin is a r h formed of: a strip of metal having a central ornamental portion 25 bent and rolled to provide an ornamental face wall and from opposite edges of which pro ect flanges 26,

the

27, which are arranged at right angles .to each other; the flange 26 serving as a hearing wall which lies in contact with the inner edges of the stiles or rails, while the other bears against the pane of glass. Through the ornamental faring-wall screws 28 are passed, that take into the and the angle bar located therein so that a pane of glass placed between the hacking molding and fastening molding is securely held in place.

he panel molding for holding the metallic panel 9 in place has each length formed of a strip of metal bent centrally into a channel-29 from the outer ends of the side walls whereof the metal is directed outward at an angle and rolled and bent to form two ornamental walls 30,'and thence inward at right-angles to the face of he door. as at 31, to form bearing walls which lie in contact with the inner edges of the stiles, or rails, and thence finally at acute angles to provide impinging walls 32 which terminate in opposite lateral extensions 33 to provide a spring projection 34 on the molding which fits into the dove-tail depression of the stile, or rail and may be sprung thereinto or inserted from either end of the stile or rail.

of two panel plates 35, 36 are held with asbestos or other sound deadening and fire proof material inter )osed therebetween.

l laving thus described our what we claim is:

1. A metallic door or the like low, stiles and rails, each invention,

having holformcd of sheet metal bent to provide side walls and an inner edge wall having a dove-tall depression,

an oblique facing wall edge of said backing means for securing said fastening molding in place.

2. A metallic door comprising hollow stiles and railshnving dove-tailed depressions in their inner edges, a panel bounded by said stiles and rails, and panel moldings formed of strips of metal, one strip being bent into substantially tubular form with the marginal portions thereof entered into and fitting against the walls of said dove-tailed depressions and the of the panel.

n'iarginal portions entering said other being bent to backing molding metal hav- 5 an angle bar fitting into the tubular moldin tO StIfi QII the same and hold the margrnalportions thereof to said dove-tailed depressions, and screws passing through the fastenmg molding and taking into the tubular 10 molding and thangle bar held therein.

A metallic door having hollow stiles and rails, each formed of a sheet of metal bent to provlde side Walls and aninner edge wall having a depression, a molding;- formed 15 of sheet metal bent into substantially tubular fOllll to provide a backing wall and a facing wall with the marginal portions of said metal bent at an angle to-fit into said depressions, a panel placed againstsaid molding, a fastening molding bearing against the edges of said stiles and rails and against the panel, and screws passing through said fastening molding and taking into the tubular lnoldin a In testimony whereof, we ha \e affixed our signatures in the presence of two subscribing witnesses. l I
