This invention relates to doors and the like,

and more particularly to doors and the like of fireproof construction.

Objects Among the principal objects the invention has in view arez-to provide a construction wherein the faces of the usual frame members of the rial in place; to utilize the edging strips on two of the edges for locking the edging strip of another edge in place; to prevent buckling of the facing material; to secure simplicity of construction and operation; and to obtain other advantages and results as may be brought out in the following description.

Figure 1 is a front elevation of a door embodying my invention;

Figure 2 is a transverse sectional View shown as taken on line 22 of Figure 1;

Figure 3 is a sectional view shown as taken on line 33 of Figure 2; and

Figure l is a sectional View shown as taken on line 4-4 of Figure 2.

Description In the specific embodiment of the invention illustrated in said drawing, the reference numeral 10 indicates a door panel, here shown as glass surrounded by the remaining portion of the door which, for convenience, will be termed as its frame and is made of appropriate upright and cross members. As here shown, a pair of upright members 11, 11 are provided at each side of the panel and are preferably of wood of appropriate cross section and length and meet and join with similar members extending across the top and bottom of the door. The several frame members 11, 11 are preferably constructed to present opposite and front faces at both sides of the door, the several front faces of the members at each side of the door being in common planes. The said faces are covered over with a facing material preferably metal, common to all of the front faces of the members on each side of the door. There are accordingly two of these facing members 12, 12, one upon one side of the door, and one on the other side of the door. By the construction thus described, it will be noted that all of the front faces of the framemembers at one side of the door will be covered or faced with a single or integral facing member, and likewise upon the other face of the door.

In the construction of the door, the facing members, or material 12, 12 are preferably applied to the door by the interposing of an adhesive between the several frame members and the facing members as at 13. This adhesive is of a character which will be capable of retaining the facing material in close contact and supporting engagement with the adjacent front faces of the frame members and preventing any buckling of the facing members away from the frame members at any part of the surface area 7 thereof.

While the inner edges, that is to say, the edges next to the panel 10, are juxtaposed to the inner edges of the frame members, the outer edges of the facing members extend beyond the outer 7 edges of the frame members and are bent at right angles so as to overlie the edge of the 7 frame member representing the thickness of the frame. In other words, the outer edges of the two facing members 12, 12 are bent toward each other in a common plane perpendicular to the plane of the front faces of the frame, thereby providing a pairof flanges 141, 14. These flanges are separated, thereby providing an opening between the entire length of the adjacent frame 5 member, and since these flanges are spaced away from the frame member, the opening with the space between the flanges and frame member provides a reentrant groove 15 longitudinal of the frame member at its outer edge.

Suitable trim is provided circumferentially of both the panel and the door. At the circumference of the panel any suitable'moulding 16 may be provided for covering the edge of the panel and the edge of the facing material and retaining the panel assembled with respect to the frame. The trim for the outer circumference of thedoor is preferably of a special construction constituting a feature of the present invention. As here 7 shown, this trim is made up of a plurality of channel members 1'7, the channel of which has a width such that it will receive the edge of the frame member together with the superposed facing material or members 12, 12 within the channel at the 1 marginal portion of the door. The outside configuration of the channel member may be of any desired shape and is here shown as shaped at its longitudinal edges to simulate moulding. Within the channel is provided a retaining means 18 adapted to interlock with the edges 14, 14 of the may be secured to the channel in any suitable: manner, preferably so as not to show from'the' outside of the channel, and for convenience, may

be brazed or spot welded or otherwise attached.

It will be noted that the channel member retains the facing members from spreading apart at their outer edges, and the facing members provide flanges for keeping the channel member'assembled thereupon.

In the assembly of the channel trim 17, the section thereof for the top of the door issl-idinto place longitudinally of itself and crosswise of the door. has its ends bevelled, as shown. Then the two sections of channel trim 17, 17 for the side 'edges' of the door can be slid into place from the bottom "and by virtue of correspondingly bevelled'ends will obtain a close lit and locking engagement with the section of trim at the top'of the door. The section of trim at the bottom of the door is applied laterally and screwed into place, the interlocking or retaining means being omitted or modified for that section. Application of this last section will retain the other sections of channel trim in place and no screws, nails or other fastening means will be visible since the screws for the bottom section are introduced from the bottom of the door.

I claim: 1. A door construction as characterized comprising a frame body having opposite front faces,

This section is of proper length and' facing members one upon each of said front faces of the frame body and each projecting beyond a common edge of the frame body for providing flanges thereat, a channeled trim at the edge of the door overlying said flanges, and means within the channel underlying said flanges for retaining the channel in place.

2. A door construction as characterized comprising'a frame body having opposite front faces, facing members oneupon each of said front faces of the frame body and each projecting beyond a common edge of the frame body for providing flanges thereat, an adhesive between the front faces of the frame body and the facing members for securely retaining said members together, channel members adapted to overlie the projectingedges'of the said facing members, and retaining means provided with offset portions on said channel members whereby said offset portions will interlock with the said flanges of the facing members.

3. A door construction as characterized comprising a frame body having opposite front faces, facing members one upon each of said front faces of the frame body and each projecting beyond a common edge of the'frame body for providing flanges thereat, an' adhesive between the front faces of the frame body and the facing members for securely retaining said members together, channel members adapted to overlie the projecting edges of the said facing members, and retaining means provided with offset portions on said channel members whereby said offset portions will interlock with the said flanges of the facing members, and said channel members and retaining means being brazed to constitute a one-piece construction.
