E. FULDA. METAL DOOR cowsmuc'now.

APPLICATION FILED ]AN.19, I916- Paten'ted J an. 27, 1920.



META noon consrnuo'non;

To in whom it may concern." 3 Be it known that I, EDWARD FULDA, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented cer tain new and useful Improvements in Metal Door Constructions, of which the following. is a specification. I M invention relates to the"construction of doors made Wholly or principally of metal. f The object of my invention is to produce a door "that shall be extremely rigid and from-sheet metal and from ordinary commercial, forms of bar iron.

To these ends my invention consists in the improved construction herein described and illustrated in the accompanying drawings wherein I have shown my invention as embodied in a door made in two sections each comprising a metal frame com osed of a flanged metal bar and having tie door or to a flange of said bar.

the following descriptionthe said flanged metal plate or facing 4/ has its edge 'submetal bars will be referred to indiiferently stantial ly flush with the face .of the bar 4 as angle iron or as Tiron;"= those being the as shownin Fig. 3. a v I ordinary commercial terms used to describe 6 indicates a strengthening diagonal made 85 respectively those forms of bar iron in of T-iron fastened in the frame 4. At the j which'the bar has, in the one case, a single corners of the frame 4 and the ends of the flange rojecting to one side thereof to make dia onal a space is left between the ends of. an angle or L-bar and in the other case has sai diagonal and the earner to allow the flanges projecting from opposite sides there corresponding corners of the section Fi 1 9o of and constituting together the head of aT.' to slip down into position when assembled.

In constructing'a door according to my In assembling the strengthening diagonals invention, I preferably employ for at least cross one another and each is recessed at one section or side of the door the L form the crossing," as shown, to allow assembly. or form having one flange only, since in the When the-sections are assembled the main 95 4o preferred construction the bar itself is made or bar portion "of one frame, for instance to constitute one edge of the dooror panel: frame .1, nests within the anglebar 4 cone in the accompanying drawings Figure 1 stituting thexframe of the other section; id is a perspective view of one-half of the door angle bar i-then forming the edgegof the and Fig. 2 is a perspective view of the other structure, The edge of the bar 4 itself en.- 100- or counter part section. gages or makes joint with the pr ojecting Fig. 3 is a cross-section.through the comortion 2 of the sheetmetal faoingfl upon pleted door. v 1 the counter "paitsection embodying the Fig. i is a cross-section through the door frame 1 and makes 'a'clean finish for the near its edge when both halves are made of edge of the doopor panel. 105

5 angle iron. As shown in Fig; 2, the bar constituting panel side consisting of sheet metal fastened For convenience in Referring first to Fig. 2, 1 indicates a metal frame consisting of T-iron bent or made up Specification of Letters Patent.

fastened to the 'flange portion 1 of said frame in any desired wayas forinstance by electric spotwelding of the bar to the inside of the sheet metal facing. I y 3' indicates a strengthening diagonal of M the frame made preferably of T-iron for greater strength. The sheet metal facin 2 projects preferably beyond the edges of lue ange of the metal frame 1 to constitute a ledge, as indicated at 2', which receives the the frame" of the opposite section and constituting also the ed e of the completed door or panel; Also tie edge of a sheet metal facin is flush with the edge of the completed 001' and is flush with the surface of the counterpart section as'will be presently C an and as shown in; the section Fig. 3.

Referring to Fig. l, 4 is the frame ofthe .75

opposite or counter part section, said frame being made preferably of an le iron while 5 indicates a. sheet metal facing secured to the flange 4 of' said angle iron bar. The a bar proper 4 constitutes the outer edge of the completeddoor or panel, and the sheet' the frame 'is slightly out down at the corners to a depth substantially equivalent to the thickness of the flange upon theframe in into a shape conforming to the outline of door panel constituting the completed struc- 55 ture and having a sheet m etalfacing 2 constituting one. side of the door. or panel the op osite section of the door and permits a. per ect fitting of the se'cgions together, while the ends of the diagona in the. section at the same time permitting the edge of 4.- to meet the inside of the plate 2'.- Also, as i will be seen, the web part of the flanged bar ,-1 engages by its edge against the. inside of shown-in; FigS Q are correspondingly cut away to'a thicknessqsubstantially equalto the thickness ofthe flanges in the'portions of 'frame and diagonal upon the-opposite or counter part section, Fig. 1, for a similarv reason. y

In order to secure a perfectly flush finish ofthe face of the door and with perfect concealment of the means for fasteningthe parts together welding or brazing is used for securing the sheet meta'lefacing to the flanges, the'welding or brazing being done on the inside Where the sheet metal facing perfectly engages the flange "of the frame. The sections or counter parts, when assembled and secured'to ether,'form a strong, rigid, and

at door or panel.

It is perfectly obvious that moldings can be paneled on the face of the. plane sheets 2* and 5 or that the said sheets ma be formed with ornamental panels or mol ings struck upor impressedtherein Without in any way departing from the essentials of the construction constituting the invention.

As shown inFi 4 the frame for both halves may be ma e from an le iron. In

this instance the metal bar 1 or the frame of one side is substantially the same as the bar 4 for the frame ofthe other side exceptin that the Width of the bar 1 is less than t e width of the bar 4 by the thickness of the flange 4 for the latter, thus ermitting the frames to be nested one wit in the other without any substantial s ace between 1 and 4, such as is shown in ig. 1, while the flange 4 of the flanged bar 4. 'VVhat I claim as my invention is 11. In a metal door or panel made in sec- ,tions, the combination substantially as described of an outer frame composed of a flanged metal bar constituting the outer edge ofthe complete door and asheet i'netal facing constituting a side of thedoor or. panel and fastened to the outer face of the Y flange of said bar with an edge of the sheet metal flush with the face of the, portion of bar constituting the edge of the door and a Icoinnterpart frame of angle iron nested fwlthili the first and having 'aY do'or side of sheet metal secured to the outer face of the flange: thereof with an projecting to receive the edge of the bar constituting the 7 edge of the door and' within which it is nested.

2. In a metal door or panel made in sectionsthe combination substantially as described of an outer frame composed of a flanged metal bar constituting the outer edge of the complete door and having a sheet metal facing constituting a side of the dooror panel and fastened to the outer face of the flange of said bar with an edge of the sheet metal-flush with the face of the portion of bar constituting the edge of the door and a counterpart frame of T iron nested within the first and having a plate of sheet metal constituting the door side secured to the outer face of the head of the T'with the sheet metal edge flush with the outer edge of the door.

5. In a metallic door or panehthe combination substantially as described, of two frames combined to constitute the outer frame or edge of the door and consisting respectively of flanged metal bars one nesting within the other, the bar of one frame constituting the extreme outer edge of the door and having a sheet metal plate 'consti tuting the door face secured to the outer surface of a flange thereof and with a metal plate edge flush with the surface of the bar which constitutes the door edge while the other orcoun'terpart frame con sisting of a flanged metal bar hasa sheet metal door face secured to the OUtBP'JSllF- face of a flange thereof and projecting slightly beyond the same to have its edge flush also with that face of the first-named having a door side or panel fastened to the flange of the metal bar by a weld between the outer face of said flan e parallel with the face of'the door and t e inside of the panel.
