The poi'xels C we fOlDlQll of two sheets of metal l), C having ("/heii' sides terminating in double sea-m members C interlocked with like double seam members A formed by flanges extending integrally from the inner sides of the A. {Hill A (see Fig; 2). In a like manner the top and bottom ends of the panels (Y. '1 terminate in double seam members C interlocked with corresponding (lou lc seam members B formed on the rails B and B (see 3).

The mirhlle 01 intermediate rail 13' is l'oi'niml of two pieces of sheet metal having choir tops and bottoms terminating inv vert-ically-extemling flanges B resting against the faces oi the sheets C, C of the panel C, as plainly indicated in Fig. 4, and the ends of the middle o1- intermediate mil B are interlocked with the stiles A, A, the same as the top and bot-tom rails, that is, by means of the keepers G and the bayonet slots H (see Fig. l). i

The fastening of each sti'i of molding I) with the oorres' oonding stile i l, A and rail B, B, i; B is the some, special reference being had to Figs. 5 and 6, which shows the molding D at the intermediate rail B.

The nioldii'ig D is formed of a single strip of closet metal hent so a desired ornamental nd )a'ovioleol will! an inwardlyilango ll i esling against the cor responding flange of the stile or roll, the said flange D lieitng engaged by a struck-up tongue I on the corresponding part oi. the stile rail (see Figs. El Md 4;). The flange l) of each molding stri ais'slso provided with an outlr u tongue 5 (see Fig. 5) mispled to abut against an opposite bent tongue or abutment K struck up on the corresponding part of the stile or rail, so that when the molding is forced in place the lug J in striking the abutment K is curved, to firmly interlock with the corresponding part of the stile or rail, as will be readily understood by reference to Fig. 5. V

In assembling the parts of the door, the flange members for forming the double seams between the Ipanels and the stiles and rail, are open to a ow of convenientl engaging one double seam member wit the other, and when this has been done, the engaged double seam members are pressed together, to completely interlock with each other, as shown in the drawings. In order to avoid a possibleopening of the double seams, the two sets of abutting double seams are fastened together by rivets L (see Figs. 2 and 3).

.In the-modified form illustrated in Fig. 8, the s aced anel sheets N, N are extended into t e rail 0, and the latter are provided with vent openings 0, registering with the space between the panel'sheets N, N and with the corrugated filling l of asbestos, so that air can circulate in the hollow door. The anel sheets N are provided with outwardly-extending frames N secured by screws 0, to a reinforcing bar O,-held on the inside of the rail under the overlapping flanges O of the rail 0.

In the modified form shown in Fig. 9, the rail P is formed of two side sheets P, P connected with each other by a cross piece I,

interlocked by seams P with the side sheets P, P Screws P connect the cross piece P with the reinforcing bar P and the flanges N 2 of the panel sheet, the said bar P and the cross piece P" having vent openings'P P for admitting air to the. air space and filling of the panel, the same as above described relative to the form shown in Fig. 8.

As shown in Fig. 10, the stile Qis interlocked with the double sheet panel Q and with the reinforcing strip Q by the double scams, the reinforcing strip extending between the two sheet-sot the panel Q to reinforce the same.

As shown in Fig. 1], the moldings l) are locked in place between flanges it of the panel sheets R and the inner side of the corresponding stile R the panel having a rein- .forcing bar it interlocked-with the stile by the double sea-ms.

The moldings D shown in Big. l2 are fas tened in place by se aratc angle irons S, one

member of which is eld in the corresponding double seam connecting the stile S with the 'panel S, and the other member clampsthe flange I) against the stile.

In the modified form shown in Fig. 13, the double seams between the stile Tnnd the panel T are inside of the stile and the said seams T are connected with each other by a corresponding bar T, having its sides curved over the said seams.

As shown in Fig. 14, the interlocking of the stile U panel U and moldingD is in a trans verse direction, an angle iron U being riveted at one member to the corresponding panel sheet, and the other member being engaged by an S-shaped flange U on the stile side terminal. Rivets Utserve to fastenthc angle iron U, the flange U and the molding flange D together.

The panel V shown in Fig. 15 is made of glass and rests on supporting members V interlocked with the double seam members V of the stile V the end of the glass panel abutting against a shoulder Von the short ene d molding V on which is secured a retaining strip V by the use of screws V to hold the glass. panel V in place. The strip V is shaped to render the appearance of the moldings alike on both faces of the door.
