panel sections 8 by welding, brazing, soldering, or any of the other methods well known in the art; In F ig. 4, I have shown both the integral moldings 1 1, which by means of dies are pressed into the desired form and which .lustrated, and theindependent moldings 15 which are applied to the door-,the form of the upright stile sections are applied to the outer faces of the flanges16 of the edging member 3 whichis preferably, although not necessarilyin the form of a channel iron member frame and m surface contact there with along their outer edge portions, with 'th'efedges of the plates 1 and 2 lying flush with theouter faces of the edging member 3, as clearly shown-in Figs. 1 and 1.

i The edge portions'of the plates 1 and 2 which are in surface contact with the. edging member 3,- are welded to the outer faces ofthe flanges 16'; of the channel members, by.

a number of's'pot weld-s 17, as shown in Fig. 4, orby roll. welds'18, as shown in Fig. 7,

which welds are disposed, preferably, near;

the four edges of the'door sideplates' 1 and As will be understood, in the electrical metalworking art, the two doorside plates 7 1 and 2 with the channeledging member 3 therebetween are assembled and suitablyheld between two current carrying spot weld electrodes 19' and 20, see F ig.j7 or the two current carrying roll weld electrodes 21 and 22,-see Fig. 9, andan lectrical current passed from one electrode to the other through the two plates 1 and 2 andjintermediate edging 'member 3 located between either. spot weld olctliodes 19 and 20, or the rollweld electrodes 21. and 22, which. eifectsthe weldingof the two door side plates land 2 simultaneously t6 the flanges 16 of the door edging member 3.

The spot welding process is repeated the desired number of timesandthespots made,

which are designated 17 are ,spacedthe desiredlidistance apart to provide ai-met'a'llic "door, orEsimilar' metallic structure,which will be practical, durable and comparatively inexpensive',i light "and neat I in appearance.

door side plates 1 and 2 to the channel door edging member 3 simultaneously.

From Fig.6 of the 'drawing,it will be observed. that I preferably employ a single strip of channel iron of the desired length and bevel the endsthereof, a s.at 23 and 2 1, and

then provide the flanges 16 thereofat predetermined-points along their. length with opvide the strip into "the four door edge face sections l, 5, 6 and 7 sothat the channelstrip I posed .V shap'ednotches 25, 26 and-27 to di-- maybe readily bent to form'a rectangular frame to act as'the edging member for the ".It'is apparent. that the space withinthe door between'the edging'member 3 and the able packing, if desired'and-that suitable in teriorbracing' may alsobe employed without the exercise of invention; hence it is not deemed necessary to illustrate thesame- Fromth'e foregoing description,'it is apparent that I have shown a metallic door structure, and set out the method of forming the same, which enables one to produce a meside plates 1 and 2 may be filled with a suit tallic door or similar structure, at greatly reduced cost over the metallic door constructions'now in use, inthat I employ three door' pieces, namely a door edging member and two door side plates, and, jointhem-together at their contacting surfaces by spot or roll welding and with both door side plates welded-to the edging member simultaneously. It is apparent that I obviate a great deal of labor in assembly and eliminate theconnectionfofthe m'any metal parts of the door which are now joined in numerous expensive ways. I a The many advantages of the herein described invention will readily suggest themselves'to those skilled in the art to which it appertains. I 7

From the foregoing description, it is evident that a silnplemetallic structure and the method of forming same for the'purpos'e has been disclosed, but it is to be understood that Ido not desire'to restrict, or limit myself to the very details of the construction shown and described,which is merely illustrative, it

being} obvious that changes, not involving the exercise of invention, may be made with out conflicting or departing from the spiritof the invention with'n the scope of the append: edclaim. What I claim is: t,

A metallic door comprising a' pair of spaced, integral sheet metalmembers consti tutingthe front and back of said door, a'panel section ins'aid sheet metal-members, molding integralwith said members surrounding said panel forming areinforcing and decorative element, a rectangular frame secured tolthef peripheries of said sheet metal members coniio i'i-s stituting an edging for said door and said 1 sheet metal membersbeing of such gauge that r In testimony whereof, I have hereunto affixed my signature. 7 v V v I v HENRY G.
