vof a form whichv will present adequate strength to vreinforce the plate against bending and still obviate the tendency` for the plates to tear in process of manufacture.

Still another feature of my invention resides in the peculiar formation of the corrugations adjacent the ends thereof, whereby said corrugations will present crests of appreciable width at their extreme ends and cooperate with other members to reinforce the 'door intermediate said members.

My invention further resides 'in an 'improved door post construction for the auX- iliary door of automobile cars and in the mechanism employe for locking the same relatively to the car s ructure. y

Other objects of the invention will more clearly appear from the description and claims hereinafter following.`

Figure 10is a sectional View taken through the corrugations and on a line corresponding substantially to line 10-10 of Figure 7. Figures 11 to 13, inclusive, illustrate a somewhat different embodiment of the door post construction.4 Figure 11 is a view somewhat similar to Figure V2, being a broken, vertical, sectional elevational view taken through the door. Figure 12 isan enlarged, broken, vertical, sectional view illustratin a different form of post construction, sai view being taken on a line corresponding substantially to a line 12-12 of Figure 13, a part of the marginal reinforcement'of the door being broken away adjacent the upper part thereof to better illustrate the construction. Figure 13 is an enlarged, detailed, sectional, horizontal view, somewhat similar to Figure 2, except. that the different embodiment of the inventlon is incorporated.

Referring first to the construction illustrated in Figure 1 to 10, inclusive, the car is prov1ded with an enlarged doorway adapted to be closed by sliding doors, as indicated at A and B, respectively. The door A is in the nature of a main door adapted to be normal-I ly used, while door B is an auxiliary door and is adapted for use only when a large door opening is desirable.

At the upper' portion of the door opening, 10 indicates the usual top side plate which is preferably 4of Z-shape construction, 11-11 the vertical door posts of the car, 12 the lower side sill of the car, 13 the car flooring and 14 the threshold plate.

In the particular embodiment shown, the doors are of the bottom supported type and for this purpose a supporting track 15 is employed, said track preferably consisting be hereinafter described. Said' track 15 is preferably supported from the side sill of the car by a series of supporting brackets 16, the door being provided with supporting roller mechanisms C. j 4

Adjacent the upper margins ofthe doors there is disposed the usual guiding ltrack and weather guard 17 which in the present embodiment consists of a rolled Z bar secured to the depending flange ofthe member 10.

The doors A and B are composed of metal, the main body portions bein orrelatively light gauge, being corrugated or strengthening purposes, and preferably consisting of a plurality of panels for each door. The panelling composing the body portion of each door is preferablyfformed in three sections, including upper, central and lower panels, said panels comprising`door A, being respectively indicated at 18, 19 and 20, and those composing door B being respectively indicated at 21, 22 and 23. The respective doors are of similar construction in so far as the upper horizontal, rear vertical and lower horizontal margins are concerned, but dier in features of construction relatin to the meeting edges of the doors. Each oor includes a top Z bar 24, and at the rear vertical margin a Z bar 25 having the inner flange thereof lmodified to present a Ufshaped portion 26 adapted to engage in wedgin relation with flange 27 of an angle mem er 28 carried by the -associated door post strucpture 11. v

The front vertical margin of door IA in-v cludes a Z bar member 29 having its web 30 extending transversely of the door, and one lof the flanges 31 thereof disposedin the inner plane of the door and projecting forwardly lbeyond the web 30 for cooperation with the auxiliary door B in a manner to-be hereinafter described.l The .outer vertical margin of the auxiliary door B consists of an angularly shaped member 32 having one of j reinforced adjacent its forward margin by a vertically disposed beam ,member 52, said the'flanges 33 thereof extending transversely inwardly of the door. The said mar ' nal members 24, 25, 29 and 32 each has a ange 34 overlying the body panelling and secured thereto by rivets 35, said anges 34 defining substantially the outer plane of the framework of the door. At the upper corners ofthe doors suitable outer and inner gussets are employed,l as indicated at 234 and 334, respectively.

The bottom of the door is formed of tubular shape -for the purpose of.strengthening the door, the formation being the same for both doors. The description therefore will be confined to one door. I n providing the tubular formation, the lower edge of the bottom panel isdeilected inwardly to provide a horizontal web 36 and thereafter downwardly to provide a de nding wall 37 spaced inwardly of the main I[indy of the panelling. On the inner side of the door a facing plate 38 is provided which is offset inwardly and provided with a vertical flange 39 which lies against the inner side of the panelling and is secured thereto by rivets 40. The facing plate 38 adjacent the lower margin of the door is offset inwardly and extends downwardly to provide a depending flange 41, said dependingl flange abutting against dependin flange 37 and united thereto by full heade rivets 42. Said late 38 is further secured to the margins o the doors by brackets 238. There are at least two roller mechanisms C per door, but since they are the same in wall sections 44 and 45, respectively, overlyinglthe main body section of the panellingl and the inwardly oi'set depending wall 37,

and 'riveted to these portions by rivets 46. The walls 44 and 45 are united by transverse integral wall sections 47, thereby forming in cooperation with said first named walls a boxlike section within which a roller 48 is disposed. Said walls 44 and 45 are extended downwardly below the transverse wall to provide walls 244 and 245 which straddle the channel members, said walls cooperating with the vertical walls 150--150 of said channel member toprevent undue outward or inward movement of the door. The roller is mounted on a pin 49 which is carried by the wall sectionsy 44 and 45 and maintained against displacement relatively thereto by a rivet 50. a The roller 48 is extended upwardly into the plane of the mainbody section of the door which is dished inwardl at this oint, as indicated at 51, thus provi ing for t e use of a large roller without the necessit for cutting away the plate panelling, it ing understood that the overlying walls of the housing compensate in strength for the dished-in portion of the panelling.

On its inner face, the auxiliary door B is member preferably consistin of an H-beam with one set of flanges 53 lylng against the `berv extending transversely of the door.

Rigidlysecured to the inwardly spaced sei;

of flanges 54 is a nailing block 56 adapted tov form a nailing means to which ain doors may be secured, said member bem secured` to both of said anges by a series o bolts 57, thebolts in the respective {ianges being prefs* lerably .arranged lin staggered relation. On

llfl

the outer or'forward side or' the transversely extending web of the beam member, there is riveted or otherwise secured an angularly shaped member 58 having one of its anges 59 extended in the general plane of the door and adapted to overlap the projecting iange 31 on the door A when the doors are in meeting relation, said flange 59 being ared at its outer end as indicated at 60, to assist in guiding the doors into meeting relation. With the doors in fully closed position, the marginal transverse wall 33 of door B is in abutting relation with the transverse wall of door A, thereby providing substantially abutting surfaces and a weatherproof joint at the meeting edges of the doors. The forward flange of the beam member 52 is disposed inl the angle presented by the door panelling, and the transversely extending flange 30 and filler castings 61 are interposed in the space intermediate the beam member and said transverse flange 30.

The doors are further braced on the inner sides thereof by diagonally extending 5 channel shapedbraces 62 which extend from the lower section of each door to the vertical marginal reinforcements, the brace leading tothe H-beam member having a flanged portion offset as at 63 to overlie one of the flanges l and is riveted thereto and to the door plate by rivets 64. Y

The strengthening indentations in the body panelling include horizontal corrugations 65 which extend clear across the door intermei diate the overlying flanges 34 of the respective front and rear vertical marginal members. The horizontal reinforcements are diy vided at a certain point of the door B for the reception of a cardboard indicated conven- 7 tionally at Y 66 andthe door is reinforced across the plane of the said board by a channel shaped member 67 disposed on the inner side ofthe door. As best shown in Figures 7 to 10, inclusive, the corrugations are formed in the panelling in such a manner that the crest'portions 68 extend a considerable distance outwardly beyond the outer' plane or face of the door, andthe valley'portions 69y are disposed inwardly .thereof so as to permit the same to be secured to the 'H beam mem' ber 52 and in certain locations to the diagonal braces 62, by riveting, as best shown in Flgure v1.l The crest portions 68 are each formed 'with a flat portion of considerably greater width than the fiat valley portions 69, thus presenting increased strength at a point considerably to one side of the main plane of the door and thereby enhancing its resistance to transverse bending or buckling stresses. The offsetting in this manner of a flat portion of extended width to a considerable distance from the main plane of the'plate is attended lwith considerable stretching of the metal and sometimes results in tearing of the metal, especially when the metal is of thin section. I

have therefore provided a novel form of connecting wall section between each flat crest and Hat valley sections, whereby Kthe major portion of the stretching will be confined to that area of metal'lying between said Hat crest and valley portions, and to this end the connecting portions which truss the crest and [length greater than one-half the depth of the corrugation, providing for uniform4 stretch of the metal throughout the/length of the arcs and thus obviating a usual cause of tearing in the corners of corrugations. By thus formmg the arcuatesportions on a large radius adjacent to fiat portions of generous width, it

is possible to confine the necessary stretch of metal t the arcuate portions, inasmuch as the initiation of a bending action in the plate causes the outer bres to stretch, and further distortion of the plate will naturally occur at the oints of least resistance. With the stretc ing of the plate restricted to the curved sections 7 and 7l, the intervening fiat sections therefore retain substantially the maximum late section, and said'iiat plate sections, y reason of being appreciably spaced from neutral axes 74 and 75 of the corrugations, effectively act as beams to prevent buckling or outward bending of the corrugations. The respective centers of -the radii 73, defining the op ositely disposed arcuate sections 70 and 7) 1, are spaced apart a greater distance than the combined length of said two radii, thus providing for the inclusion of the fiat section 72 intermediate the curves, and confining the stretching of the material to 7arcs of approximately 60 as indicated at 6.

AThe corrugations adjacent their ends decreasein depth as indicated at 77, and said decrease in depth is accompanied by a corresponding decrease in the size of the connecting curves so that the respective curved sections 70 and 7l gradually decrease in size from a maximum at the point of maximum section of the corrugation to a common vanishing point atthe extreme end of the cor rugation as indicated at 78. Said oppositely disposed curved-sections, due to the gradually decreasing size of thecurves from a maximum to a vanishin point, assume oppositel disposed cone-li e sections as indicated y 79 and 80, respectively, saidsections bein separated by a flat wall section481 whic alsol decreases and finally 'merges in'to the common vanishing point 7 6 whichyalso constitutes'the ,apex of the cone-like sections79 and 80.' vThe flat-crest eect for vthe outer portion of the Cil j ing pin 92 adapted to maintainthe bolt in corrugation is continued clear to the ends vof.

the corrugations, said corrugations at their extreme ends being of appreciable width'as indicated at 82, but of slightly reduced width as compared with the main body of the corrugation, the extent of said reduction in Width being only that necessary to produce a true conical formation for the outer sections 79 and 80, and therefore the extreme outer boundary of said flat portion coincides with thev vanishing point 78, the latter being determined by prolongation of the bisecting line 83 of the outer curved section 70 until the said line intersects the main 'plane of the plate. The corrugations .having crests of appreciable width at their extreme ends, coupi led with the fact that said corrugations commence immediately adjacent the overlying fianges of the vertical marginal members, asg sures adequate strength adjacent `the auxiliary marginal members and overcomes a weakness common to all metallic doors of which I have knowledge.

It will thus be apparent that by .restricting the stretching of the material to the curved sections and by gradually reducing the same as the corrugations reduce in depth, that a construction is obtained wherein the stretch of material is uniform 'throughout the entire length of the corrugation and bunching of metal Aat the ends lof the corrugation Aprevented.

The auxiliary door is provided adjacentits meeting edge with anchoring means which preferably consists of upper and lower sliding bolts, as indicated at 84 and 85, said bolts being respectivly movable 'into engagement with sockets 86 and 87, respectively disposed on the car structure adjacent the u'pper and 'lower portions of the door. .Said bolts are preferably mounted in substantialalignment with one vertical'row of rivets connecting the beam member 52 with the. door plate, whereby strains against the door will be communicated 'squarelyvto the rivet heads. Said bolts and flanges 53'and 54 of said member.` Brack. et 89 is disposed at an appreciable distancey from the top of the door, respectively secured to the web 55 and adjacent flange 53 of the' H member. Said member is further provided with a ledge 96 on which a laterally extending head 91, formed integrally'with the upper bolt 84 is adapted to seat. Cooperable with said laterally extending head isa slidlockedv position. A bracket 98 is; secured to the web of the H member for supporting said bolt when in inoperative position.,v

Abolts to to one o the transverse walls 111 and to the outwardly, spaced wall 114 are brackets 117,

The lower bolt is slidably mounted in bracket 94, said bracket bein mounted on the youter face of the `fianfre 54 o member 52 and is rovided with a ledge on which a lateral extending head 96, formed integrally with the said bolt, is adapted to seat to maintain the bolt in inoperative position. While I have shown the sliding bolts on the side of the post member inwardly from the edge of the door, it will be understood that the same may be applied on the opposite side of thepost.

In the construction shown in Figure 3, the doors are of similar construction except that the overlying flange of the angle member 59 is disposed on the opposite side of the projecting flange 31 of the Z shaped member from that shown in Figure 2.

In the embodiment shown in Figures 11 to 13, inclusive, my improvements are shown in connection with a different embodiment of vindicates the outwardly spacedwall and a "nailing block 'secured to the outwardly spaced wall by bolts 116, one of the walls 111 having perforations 211 in line with the errnitA access to the nuts. Secured 118 and 119, thebracket 117 forming a carryingf member for lower sliding bolt 1 20 and brackets 118 and 119 forming' carrying members for upper sliding bolt 121. The sliding bolts 120 and A121 are formed with laterally' extending heads 122 adapted to respectively cooperate with ledges 123 and 124, respecj tively, .formed on brackets 117 and 119 to maint-amA the sliding bolts ina given posiare mounted 1n positions to be readily visible .tOIl- .Cooperating Withthe head 122 0f slid" ingbolt 121 to-maintain the same in projected position is a detachable pin member 125. The respective sliding bolts 120 and 121 are disposedin' substantial alignment with one ofthe vertically extending rowsV of rivets 118,

and transversely in line with6 the reinforced marginal portionv of the door, whereby the strains are transmitted directly to thestrong` est portion of the door. The locking bolts are shown adjacent the outercorner of the post with the laterally extending heads extending in the plane of the wooden block.
