The same part is designated by thesame reference numeral wherever it occurs throughout the several views.

In its essential features a metallic door embodying my invention consists of two sheet metal panels suitably pressed to the required shape and contour and secured together at their edges to constitutethe door, the panels being separated from each other a distance to afford an interior chamber or reeess' The lock mechanism consists essentially of a locking bolt, an operating lever handle therefor, and a spring normally acting to maintain the bolt projected. These parts readily separable with relation to each 7 other and they are not connected through any screws or other attaching devices, and the locking bolt is carried in a. housing which is arranged within the ohamber between the door panels and suitably secured to the outer face of the inner door panel.

Referring particularly to the structure shown 6 designates the outer panel and Tthe inner panel of the door structure. Each of these panels is stamped out of sheet metal, the side. and bottom edges of the inner panel being bent out of the plane of said pane] indicated. at 8, 9, Figs. 2 and 3, and into suitable curved shape or form along the front edge of the door to receive and overlie the rubber or other bumper blocks and guiding lugs as indicated at 10. At its extreme edge bounding the verticalsides and lower edge of the door the flanged portions 8, 9, of the inner panel are formed into lips 11, over which are engaged bent flanges 12, at the bounding edges of the outer panel 6, as clearly shown in l igs. 2 and. Of course the inner and outer Wall panels are formed into the desired shape and contour to follow the outlines of the vehicle or other structure to which the door is to be applied.

The inner panel 7 is pressed into shape to form a depression 13, centrally in the in ner surface thereof, that is, 'the surface which presented to the interior of the vehicle body. Across the lower portion of the open face of the depression mseat is secitlred a plate 35, thereby forming the pocket, with which (automobile doorsare 0rdinary provided. If desired a strengthening bumper or filler plate 36 may be inserted between the outer surface of the wall of the depression and the inner surface of the outer door anel 6, as clearly shown in Figs. 1 and 2, a though this is not essential. This structure of'door and pocket is exceedingly simple, efiicient, satisfactory and inexpensive to produce. The door hinge straps 14 through which the door is hinged to the adjacent post of the doorwayaresuitably secured into the door structure at the rear edge thereof. A simple and very satisfactoryway of accomplishing this is shown whereinthe-ends37 of the hinge straps extend through slots in the. inner panel 7, into the space or chamber between the panels, and are welded or otherwise integrally connected to the inner surface of the flange 8 at therear vertical edge of the door. This produces a strong durable structure which is economical to manufacture. Adjacent the front edge of the door structure the inner panel is provided in its inner surface with a depressed seat portion 15 stamped therein to receive and accommodate the handle 16 of thelock mechanism. The inner panel is slit at 17 to permit the lever 16 to extend through the slit' and into the. interior chamber 18, formed between the two panels 6, 7. The bolt 19 is housed within chamber 18, and its outer end projects through an opening formed in the flange 9 at the front edge of the inner panel, said bolt being retained in place by a housing or strap 20, in the I form of a metal channel 20, havin edge flanges which are applied and securedtothe inner surface of the panel 7 or to a plate 38 which isapplied to the inner surface of said panel. This plate has a looped end 39 which carries a stud 21 which is straddled ,by a fork formed at the inner endof lever 16, when said lever is in working position, thereby forming a fulcrum about 'which said lever rocks in operating the bolt. The bolt is engaged in any suitable manner by the lever 16. A simple arrangement is shown wherein the bolt on its inner faceor Surface is recessed as indicated at "22, and

in assembling the bolt and its operating lever 16, the latter passes transversely through said depression. On its rear edge the lever 16is formed, with a rounded proi j'ecti'on 23 which works against the inclined wall or surface 24 which forms a rear boundary of the depressed seat 22 in the bolt. Thismaterially reduces friction and secures an easy operation of the bolt. Adjacent the extremity of the rounded projectionv 23 of the' leversa'id lever is provided with shoulder 25, see Fig.4, into which extends the extreme outer corner-26 of the adjacent 'wallof the recess-22, thus f'ormingastopto normally retain the lever in its assembled relation with respect to the bolt." A-coil spring 27 is inserted within the housing 20 and normally exerts its tension against the inner end of the bolt in a direction tending to project the bolt outwardly. The engage ment of the lever 16 in the depression 22 of the bolt, of course prevents the bolt fromthe bolt. While this is a simple arranger Y ment my invention is not to be limited or restricted in this respect.

In order to assemble the parts of the lock the spring27 is inserted into the housing 20 and then'the bolt is inserted so as to bear against the spring and is pressed inwardly as far as possible. This will bring the seat 22 in the bolt in-line with the slit or opening 17 in the inner panel and into position for the lever 16 to be inserted through said slit 17 and through the housing 20 and through the seat or depression 22, and into position for the forked end thereof to engage the stud 21, the corner 26, when the bolt is released after inserting the lever, snapping against the shoulder 25 and the rounded surface or projection 23 bearing against the wall 24 of the recess 22." The parts are now in positionassembled for operation. Inorder to remove the lock mechanism the reverse of the above operation takes place that is to say, the bolt is pressed inwardly as far as it will go, this action releasing the projection 26 from shoulder 25, and then the lever 16 may be readily and easily withdrawn endwise through the seat 22. The. bolt may then be pulled out and the spring removed from the housing. A look mechanism such 1 subj'ected to the usual enameling heat with the spring of the lock mechanismremoved and consequently the danger of injuringthe temper of the spring through the action .of the enameling'heat is" avoided.

It will also be. observed'that no tool is re quired in order to effect the assembling or removal of the lock structure. .If desired, and in order to impose a desirable friction upon the bolt operating lever,

lot!

a nd'tohold the same in the proper plane of operation a rib may be stamped in the de piesaedi portion of the inner panel and arr, ra; ged toextend transversely of the lever 16 5 and-against which the lever operates.

Interposed between the upper edges of the inner and outer anels (i, 7, I prefer to insert ablemeans f terialor strip for the door. A simple arr angement is shown wherein a box sl'laped stamping 29 is inserted between the upper edges of the stampings 6, 7, said stampings I at their-upper edges being suitably bent out l' f wardly or away from each other to form asnitable seat for the member 28 therebetween. and the extreme edge of one of said panels, fasdfor instance, the outer panel 6 bent UMBI' the u per side or-edgelof the member All 0 the parts constituting the door, ttore, and; including the housing may int rally eeenreditogether or to their ad arts integrally in any suitable or nt manner. For convenience of conmn. manufactor l. prefer to spot weld the parts,
