, Patented Aug. 1, 1933 BATENT F C VEHICLE DOOR CONSTRUCTION George Trautvetter, Philadelphia, Pa., assignor to Edward G. Budd Manufacturing Company, Philadelphia, Pa., a Corporation of Pennsyl Vania Application January 16,1932. Serial No. 586,998

3 Claims. (01. 296-44) The invention relates to vehiole'body doors and more particularly to such doors built up out of sheet metal.

- It is an object-of the present invention to -5 simplify the construction of such doors parappearance than has heretofore been attained;

These objects I have in a large degree .attained by the construction shownin the accompanying drawing illustrating a preferred embodiment of In the drawing, v Fig. l is an inside perspective of an outer panel stamping according'to the invention.

Fig.2 is an enlarged fragmentary perspective 23520 view, parts being shown in section, showing the construction of aivertical door rail at the side of the window opening.

Fig. 3 is asimilar view at an upper corner of the door showing the top rail in section.

In the drawing the invention has been shown applied to a door built up principally of outer and inner panel stampings, such as is shown, for example, in my prior application Serial No. 421,374, filed January 1'7, 1930 for pressed metal doors, but it will be understood that certain features thereof are applicable whether the door involves the use of acne piece inner panel extending entirely around the window opening or not.

According to my invention the outer panel 10 is formed as a one piece stamping having edge flanges 11 adapted in the final assembly to be crimped around the edge flanges 12 of the inner 4D framepanel 13 and spott welded thereto. The side and top rails of the door are shown as forming portions of an inner panel stamping Y 14 also extending entirely around the window opening.

The side and top rails surrounding the window openings are shown as comprising generally transversely extending portions 15 forming the door jamb, and outer laterally extending edge flanges 12, about which the outer panel edges are crimped as already described. In the present instance this transverse jamb portion is shown provided with an offset, to fit against a corresponding offset in the door frame, but it will be understood that this invention is equally applicable to door jambs not provided with such an offset.

vwidth of the jamb'face portion 15 spaced from portion 15. a

The inner panel in the sides and top of the window-opening has this jamb portion 15 reversely. bent to provide moulding around the window opening, and providing a transversely extending portion 16 of less width thanwthe 0 the latter and providing a seat against which may be secured "a removable moulding, not shown, for retaining and guiding the window.

The outer panel lo-is turned in around the 5 eluding a portion 19 extending toward the .jamb and forming the outer wall of the glass run,'*a portion 20 extending transversely inwardly and forming the bottom of the glass run,,'a portion 21 extending to the jamb portion 15 of the inner panel, and a portion 22 overlapping the jamb v V ,75 The edge of the inner panel portion 16 is in substantially the plane of the portion 21 of the outer panel and its edge overlaps the inner edge of the portion 20 and is secured thereto by spot welding. Preferably in order to localize the 89 heat and facilitate the weld the outer panel portion is formed in the overlap with spuds 22 which are melted down by the heat of the weld, leaving the parts seated flush in engagement with each other as shown. The portion 20 may also be provided with a shallow offset 23 of the thickness of the inner panel to receive the edge of the inner panel, thus leaving a smooth flat transverse surface from the inside of the opening to the outer side wall 19 of the glass run.

The portion 21. forms a rigid brace between the portion 16 and the jamb portion 165, permitting the welds to be made by having the electrodes engage, respectively, the outside of the jamb portion 15 and the inside'of the portion 16 without danger of collapse of the parts toward each other under the pressure exerted by i the electrodes, and also furnishing additional strength to the rail in the final assembly.

The overlapping edge flange 22 of the outer 9 panel is preferably spot welded to the jamb portion 15 of the inner panel to further stiifen and brace the structure and prevent squeaks due to relative movement of engaging metal parts, and this spot welding is preferably carried out prior to the attachment of the edge of the inner panel portion 16 to the portion 20 of the outer panel .to insure greater rigidity during the welding of these parts. Access is provided for directly spot welding the flange 22 1;

to the jamb portion 15 through spaced openings, as 24, provided at suitable distances in the transverse portion 16 of the inner panel. Spuds are provided on part 16 to facilitate the weld and to minimize weld marks.

From the. foregoing description of the construction and methodof assembly of the improveddoor it will be seen that I have provided a very strong rigid and durable construction of door rail, and a construction in which the parts are well adapted for ready assembly by spot welding and also one in which "a neat and'fi'n-' ished appearance is preserved in a very high degree. Y

Thefeatures by which these advantages are attained may be modified within the skill of one skilled in the art, without departing from the spirit. and scope of the invention as expressed in the claims appended hereto,

What I claim is: 1. A metal widow rail construction built up of inner andouter stampings, the inner stamp ing having a transverse web portion forming the jamb portion of a door and its inner edge reversely* bent, the reversely bent portion being 2. A metal window rail construction comprising an inner panel having a transversely extending. web portion forming the jamb portion of a door and having its inner edge reversely bent, the reversely bent portion being spaced from saidjamb; portion-and a stepped glass run; channel member comprising a portion of double angular form, the one angle forming the outer side and bottom of the glass run, the portion forming the bottom of the glass run being offset along its inner margin to approximately the thickness of the metal of the inner panel the: reverselyv bent portion of the inner panel overlapping and secured to the offset portion of said memberforming the bottom of the glass run, andsupported in spaced relation from the jamb'face portion by the other angle of said double angular member.

-3. A metal window rail construction compris- 1 ing'a reversely bent inner panel providing spaced transversely extending portions, one of greater width forming the jamb face'of the door and the other of, lesser width forming a seat for removable window moulding, and an outerpanel having its inner margin formed of double angulari form providingv a stepped formation, one step forming the bottom of a glass run, the margin of saidlesser width portion of the inner panel being spot welded to said step, and the bottom ofthe other step being spot welded to the jamb face-portion of said inner panel, openings being provided in the lesser width portion to permit access oi the welding. electrode.
