MEIIALLIC STRUCTURE, SUCH AS DOORS AND THE LIKE.

Tu cZZ whom it may concern:

lie it knownthat l, lTlARULl) l lAlllSll, a

. citizen of the United States of America, and

residing in the-borough of Brooklyn, in the county ofliings and State of New York, have invented a certain new and Improved Metallic Structure, Such as Doors and the like, of which the following is a spcciticzv tion.

My invention relates to metallic structures such as doors, partitions, frames and windows and the object thereof is to produce a metallic structure of improved artistic appearance which can be economically manufactured and which shall be light and at the same time strong.

Further objects of my invention will be hereinafter referred to in the following detailed description of the invention. V

In the accompanying drawings, the invention is illustratedina metallic door, but it is to be understood that, except as specifically pointed out, the invention is susceptible of modification without departing from the spirit of my invention and it is equally applicable to structures other than doors.

Figure 1 is an=elevation of a door embodyingmy invention; Fig. 2 is a broken section thereofion'the line .22, Fig. 1 drawn to a largerscale; and Figs. 3 to 8 are sections'of modified details.

The structure illustrated is a door of the type in which the frame members, via, the

stiles 10 and 11 and cross rails 12, 13 and it neled construction.

of-each face oft-he door, are integral and the door frame is completed by suitably securing together these two opposite faces B at the edges of the door. Where panels 15 and .16 are employed as illustrated, these are independent from the frame members and are held in position upon-the frame lly suitable securing means. The structure is thus distinct from-the type of the 'door i1 which Specification of Letters Patent. I Pgmtentgd 348; Egg} 1% Application filed May 20, 1912. Serial No. 698,503.

curing together the two door faces maybe varied in many ways, I prefer to effect-this, for the top rail and stiles, by bending'over at right angles and for an equal distance from each facetheir respective margins 17, the edges of which are recurved to form open channels 18. The bottoms of the latter, in assembled condition, are thus 'jmxtaposed on a line midway between the two door faces. T 0 unite these edges and at the same time to stiffen and strengthen thedoor, I provide a stiffening bar 19 extendingas a strut member between the inner faces of the two sheets A and B and having its edges recurved to engage and interlock with the channels 18. The parts may now be elecw trically welded or-riveted together, preferably the former, as giving the more finishedappearance. it will be observed that inthiscondition the edges of the door are closedon three sides, while the bottom edge is left open for the purpose of perfecting-the hint at theedge of the lower panel as will be hereinafter explained.

Presuming that the upper panel 15 to be inserted in the registering apertures of the door is to be a pane of glass, the

edges of the plates A and B at theglass aperture are cut on the miter at the corners and the edges are folded inward to form an open channel 21 and then recurved to form a second and parallel channel 22 oppositely faced. A molding 23 with glass supporting ledge 24 spans the space between faces A and B, and its edges are insci-ted in the opposite channels 22. ening bar is also spaced between the plates A and B with the side flanges of tlie barinserted in the opposite channels 21. After the glass 15 is in position, a retaining molding '26, one edge of whiclrentcrs the channel 22, is pressed against thc face.of the glass and is drawn into snug engagement therewith by screws 27 which enter threaded holes in the reinforcing bar 28 welded or otherwise secured to one face of the supporting ledge 24.

The advantage of the construction shown is obvious, since it permits thereadyremoval of the molding 26 for the insertion of a panel of glass. If thispanel ismade of non-o breakable material so that replacement is a0 1 A stitfnot likely to be necessary, the construction employed for the lower panel is preferred. At the lower panel opening the edges of the apertures are fdlded on three sides to a panel supporting nmlding tion only, to form the single. channel 31.-

For a one piece panel 16, as shown in Fig. 2,

33 with panel receivingslideway 34. is spanned between the channels 30 on'three sides. At the bottom of the panel the construction must be different in order to permit the insertion of the panel which is slid through the bottom of the door into the depression 34: of the side and top molding 33. A following and supporting molding 35 engages the lower edge of the panel and is in turn held in position by the stiffening bar 36, the channels 37 of which receive the edges of the molding and theinner edges of the opposite channels 31. The parts are secured together in any suitable way, preferably by welding.

Thebottom of the door, which has been left open for the insertion therethrough of the panel 16, moldin 35 and stiffening bar 36, is closed by an lnverted stiffening bar 38, the edges of'which are turned down and welded in the channels 89 formed by the upturned edges 40 of the bottom margins of the side plates A and B. A recess ll is thus afforded for the reception of weather stripping or other material which it may be desired to arrange at the bottom of the door.

Themanner of constructing and assembling the door is readily understood and may be varied in many ways. .For example," the blank of sheet metal is first formed with the central apertures for the panels, and the margins of the panel apertures and of the sheet as a whole then folded to form the edges of the door and the inturned keyways or channels. At the corners of the door the metal is unavoidably cut away slightly to afford clearance for the folding d1es, and sufiicient room is thus afforded at the top of'the verticaledges for the passage of the fiat reinforcing key bar 19 through the clearance space at the corner into engagement with the" channels 18. This corner seam is in any event unavoidable, by reason of the fact that the margins of the sheets arefolded oyer, both at the top and at the sides of the ,door, and the insertion of the key 19 aids in filling the seam which is closed by a line of solder, or electrical welding in accordance with the process disclosed in my Patent 1,034,290. The keys 19 for the vertical edges of the door are then passed into enga ement with the channels formed thereon, t e'keys being insertedfrom the bottom of the door, at which point the clearance for the folding dies is formed. The. faces of the door are now united, with the panel apertures in register. The uppermost stifl- Lose-934. I

ening spacer bar 25 is now placed in position by passing it up sidewise between the recurred marginal edgcs 21 at the panel aperture. and then drawing it down into the position shown. Any suitable means may be employed for this purpose, 5]., a wire welded at one end to the barand cut off after the latter has been drawn down into position. The bar 25 is then secured by welding the joint between the same and the bottoms of the channels 21. The molding 23 is then placed in position, the panel 1?) inserted and the retaining moldin 26 screwed into position. The second spacing bar 25 is then passed up from the aperture for panel 16 30 and welded in position, thus completing the upper portion of the door. The lower portion is inlarge part a repetition of the upper part, and no difficulty will befound in understanding its assembly from the preceding description. p

A door thus constructed presents the great advantage over a doorassembled from independent stiles andrail members that the welding of all joints betwee v the parts may be accomplished from the interior of the door, thus presenting an exterior free from the blemishes or blisters which in eritably accompany a welded joint. Further y .it' presents great advantages over a door 5 with depressed panels in that it permitsof a variety of design and artisticity of mold ing which are wholly beyond the range of practicability for doors of the pressed panel type.

Obviously the particular moldings and closures may be varied in many ways. Thus in Fig. 8 l have shown the bottom edges of the faces A and B'carried down perfectly straight and the opening closed by the inser- 5 tion of a flanged stiffening bar 4:2 which is welded in position. In Fig. 4 I have shown a modified form for the edges of the top cross rail and stiles. The edges of the latter are folded to form parallel oppositely o faced channels 43 and 44, in one pair of which engage the-edges of a flanged stiffening bar 45 and in the other pair an 0pp0-- sitely faced stiffening bar-46. ln Fig. 5' the panel is supported directly by the stiffening bar 47 and-moldings 48 are arranged on each side of the panel to give a'finish' to the joint. In Fig. 6 the panel supporting molding 49 is provided with upturned edges 50 which engage in the channels 31 at the lower edge of the panel aperture, together with the flanges of the stiffening bar 51. The latter in turn may be reinforced by asecond stiffenin bar 52' oppositely faced.

and sides of the panel, be engaged in the channels 30, while the bottom edge engages in the channels 37 of the stifiening bar 36.

()r as in Fig, 8, the lower edge of the panel may be recu'rved to engage in the channel 31 with the flanges of the stiffening bar 51.

panel supporting means have been assembled I in position.

A metallic structure of the character described comprising front and back face sheets having rail and stile portions and having registering perforations to receive an inserted panel section, the margin of said panel perforation being folded and recurved on certain sides to form parallel ,oppositely faced channels, and one margin of said panel aperture being folded in only one direction, for the purpose described.

3. A metallic structure of the character described comprising front and back face sheets having rail and stile portions and having registering perforations to receive an inserted panel section, the margin of said panel perforation being folded and recurved on certain sides to form parallel oppositely faced channels, and one margin of said panel aperture vbeing folded in only one direction, together with panel molding engaging in the channels facing the channel aperture, and stiffening bars engaging in the oppositely as described.

4. A metallic structure of the type described, having front, and back face sheets, each comprising rail and stile portions, the top faced channels, substantially and side margins of the sheets being folded at right angles and their edges recurved inwardly to form open channels, the bottoms of which unite to form an edge closure for the structure, stiffening bars engaging. the opposed faces of the door and having their edges angled into locking engagement with said marginal channels of the front and back face sheets, in combination With means insert-ible at the remaining edge of the structure after the other edges are closed, spacing said edges apart but forming an edge closure, all the edges of said structure being continuous and free from aper tures, fill pieces or the like, substantially describe I I In testimony whereof I have signed my name-to this specification, in the presence of two subscribing Witnesses. 4
