Application March s1, 1932.` 602,146' `2o claims. (ci. ias-isi` This invention relates to improvements in transportation containers and lore particularly doors therefor.

One object of the invention is to lprovide a door arrangement for transportation containers of the railway type wherein "the construction consists of the minimum number of parts relatively inexpensive to manufacture and assemble. Another object of the invention is to provide a door construction particularly adapted for transportation containers wherein all the fixtures for hingedly mounting the doors, latching the same, and to provide shrouds4 for certain parts of the locking mechanism, are consolidated into two preferably cast units. f

Still another object of the invention is to provide a door construction of the type indicated in the preceding paragraph wherein provision is made for Ventilating the interior o er to eliminate sweating.

A further object of the invention is to provide *g1 a transportation container having doors lwithsealing means in the door joints wherein provision is made for Ventilating the interior of'the container through the doors without danger of admission of rain or other foreign matter to the interior of the container.

Still another object of the invention is to provide a container and door construction in vac- 39 cordance with all of the preceding objects of invention wherein the arrangements may be incorporated in either a. two door arrangement or a double door ofthe folding leaf type arrangement.

Other objects of the invention will more clearly appear from the description and claims here-A inafter following considered in connection with 'the drawings and forming a part hereof. In said drawings, Figure 1 is an end elevational 4.0- view of a railway type of container showing theimprovements incorporated therein, parts being broken away in Aorder to better accommodate the view on the sheet. Figure 2 is a part horizontal. sectional view, part top plan view of the top edges of thev doors when'in closed position, parts being broken away at one end to accommodate the view on the sheet.. Figure 3 is 'a horizontal sectional view, corresponding to the linel 3-3of A Figure 1. Figure 4 is an enlarged detailed horizontal sectional view, corresponding to the line 4-4of Figure 1. Figure 5 is a view similar tov Figure 4, corresponding to the line 5--5 of Figure 1. Figure 6 is an enlarged vertical sectional view, corresponding substantially to the linel 6 6 of Figure 1, parts being broken away in order to accommodate the view von the sheet.

Figure 7 is an enlarged vertical detailed sectional view, corresponding to the section line 7-7 ofFigure 1. And Figure 8 is' an end elevational view of one end of a door.

of the containy In said drawings, a portion of the end sheathing of the container is indicated at 10.; the roof sheet at 11, the side posts of the door opening at 12-12, the sill at 13 and the lintel at 14, the latter havingan upstanding outerflange 15,` horizontal web 16 and inner depending flange 17. Over the door opening and secured to the roof sheet is extended a combined drip and weatherprotecting plate 1'8 sloped along its top edge, as4

clearly shown in Figure 1, downwardly to each side from the center. The lintel '14 is preferably braced .by a reinforcing plate 19 secured,

along its lower edge to the-depending flange 17 and along its upper edge to theroof sheet, as

indicated in Figure 6. On the upper flange of thesill 13 is secured an angular threshold plate 20 and a portion of the plank flooring is indicated at 21, there preferably being a floor sheetl 22 beneath the planks, as indicated.

In the particular arrangement chosen for illustration, the door opening of the container is closed by two pivoted doors, each comprising two pivotally connected leaves, the leaves being designated broadly as A-A for the two outermost leaves and .B and C for the two inner leaves, it being understood that the two outer leaves A-A are of like construction oppositely arranged, whereas the two leaves B and C differ somewhat in detailed construction at their meeting edges, as hereinafter pointed out.

In carrying out the invention, each door or 'door leaf, as the case may be, is comprised of five 4leaves is believed to be sufficient except as additional description may be required for certain detailed differences hereinafter set forth.

Referring'to the outer leaf-Aappearing at the left of Figure 1, the same comprises an upper' casting 23, a lower casting'24, two angle side bars or reinforcing elements 25-25 and a sheet ing one or more integrally formed reinforcing corrugations .27 therein extended outwardly.

los' .metal closure panel 26, the latter'preferably hav-y Each casting 23 and 24 is provided. at that end adjacent the corresponding door post, with a plurality of integrally formedhinge lugs 28--28 to which-vis plvotally connected a hinge link 29,-

the latter in turn being pivotally `connected to' hinge butts 30-30 in turn secured to the door post, this link or articulated type of hinge being employed on account of -the door being of the double leaf type. Each of the castings 23-24 is also formed at its opposite end with integral .hinge lugs 31--31 to provide pivotal connection with the corresponding upper and lower castings 37 and ending in a depending flange 38. Each of 33 thereof and near each end and, in the top wall 34 thereof, with a centrally located opening 40, it being observed that the openings are longitudinally offset from the openings 89 so that a broken or interrupted passage is formed for air circulating through said openings. Each of the upper openings 40, when the doors are in closed position, are alined with corresponding openings 41 in the web section 16 of the lintel and to permit circulation of air to the interior of the car, the lintel reinforcing plate 19 is also provided with vent openings 42. In this manner, as will be evident, notwithstanding that the edges around the doors are sealed with gaskets as hereinafter described, circulation of vair between the exterior and interior of the container is permitted through the upper castings of the doors without danger of rain or the like being admitted to the interior of the container.

Each of the lower castings 24 and 133 of the door leaves A and B, respectively, are similar to the upper castings, that is, each is formed with an integral box section having outer wall 43, top wall 44, inner wall and bottom wall 46. The outer wall 43 has a depending flange 47, which functions as a weather seal for the joints along the bottom edges of the door, as best indicated in Figure 6. Each back Wall 45 is extended upwardly, as indicated at 48, and is then laterally outwardly offset, as indicated at 49 and terminates in an upper flange 50. The bottom castings likewise are provided with ventilating openings consisting of holes 51-51 in the outer wall 43 and a plurality of openings 52-52 in the inner wall 45, the latter being longitudinally offset from the openings 51, asbest indicated in Figure 1, thus providing broken passages for the air and preventing .admission of foreign matter to the interior of the container. All bottom castings will be similarly provided with ventilating openings, as will be understood.

Referring again to the upper castings, as best each is formed in its upper wall with a longitudinally extending depressed groove 53, which serves to collect any moisture that may enter the joint between the tops of the doors and the lintel and such collected moisture will drip down through the openings 40A and is then drained off, on the outer sides of the ydoors, through drain holes 54-54 formed in the bottom Walls 35 of the castings.

Each of-the side braces 25 is preferably a rolled angle and is riveted at i'ts ends to the upper and lower castings by both of its flanges as by the rivets 55 and 56. To accommodate the inner iiange of each angle, the castings are recessed on their inner faces an amount corresponding to the thickness of the flange, as indicated at 57, and similarly on their outer faces, as indicated at 58, so as to provide a flush arrangement between the angles and the castings. As will be understood, the ends of the angle or side elements 25 are overlapped on the castings a sufficient amount to obtain the necessary attachment. Inthis connection, it will be observed that, by merely changing the lengths of the side angles 25., the same upper and lower castings may be employed for doors of different height, thus reducing cost of fabrication where doors of different size are required.

The sheet metal panel 26, preferably one piece, has its upper edge lapped under the depending flange of the upper casting, as indicated at 59 in Figure 6, and has its lower edge lapped on the outer side of the lower casting, as indicated at 60, so as to form shedding joints and prevent collection of moisture and resultant corrosion.

Along the side edges, each sheet metal panel is lapped over and secured to the outer face of the corresponding side angles 25, as by the rivets Referring to the upper and lower castings on the door leaf C, said castings at the free edge of the door leaf are somewhat modified so as to provide flanges 62-62, which are inclined outwardly and backwardly, as best indicatedin Figure 5, and the corresponding edge angle 125 has its outer flange 126 correspondingly bent and riveted to the casting flanges 62. and lower castings of the door leaf B are correspondingly modified, as best indicated in Figure 5, each of said castings having an outwardly extending flange 63 and a terminal ange 64 at right angles thereto, the flanges 64 being adapted to engage over the edge formations of the door leaf C and consequently, serving to hold the latter in closed position when the door leaf B is closed and latched, as will be clear from Figure 5. The corresponding edge angle 225 of the door leaf -B has its flange 226 similarly inclined and riveted to the castings so as to be parallel to the flange 126 of the angle on the door leaf C. y

Each of the upper and lower castings of each of the door leaves B and C is further provided at the end pivotally connected to its corresponding main door leaf A, with an integral hook shaped lug 65 extending inwardly as shown in Figures 2, 3 and 4, said hook lugs being adapted to enter through corresponding slots 66v and 67 in the door lintel and threshold plate respecclosed position, the hooks thus engaging behind The upper the lintel and threshold plate and serving to retain the doors in closed position, as will be understood.

To latch the doors in closed position, the following arrangement is provided. Riveted to the door leaf B, the last to close, is a bearing casting 68 in which is rotatably journaled a plate 69 to which are pivotally connected upper and lower locking bars 'I0-70. For operating the bars and plates 69, the platehas pivotally connected there-` to a hasp handle 71 adapted to take over a staple ing therewith except by authorized holders of the key for the lock.

As best shown in Figure 6, the upper and lower castings on the door leaf B are formed with vertically al.ned guide or bearing openings '76 in the top and bottom walls of each of the box sections for the enlarged ends 77 of the locking bars which, when projected upwardly and downwardly to their maximum extent, enter openings 78 and 79, respectively, in the lintel and sill to hold the doors in closed position, it being thus evident that the castings provide shrouds for the locking bars.V

To seal the several joints between the doors and the door framework, between the two leaves of each door and between the meeting edges of the two doors, any suitable yieldable sealing arrangement may be provided, the one shown comprising a special rolled rubber section 80, as best shown in Figures 4 and 5. Each such rubber strip has a relatively thin flat central portion and enlarged rounded cored edges or beads. The rubber strips will be applied to the respective vertical edges of the doors as by clamping plates 81 and rivets 82 and also along the inner faces of the top castings, as indicated at Figure 6. the.

latter sealing strips cooperating with the lintel fiange 17.

From the preceding description` considered in connection with the drawings, it will be observed that between each opposed vertically extending surface of two doors and opposed surfaces of a door land fixed part of the container, a double line of seal is provided by the two beads extending lengthwise of the opposed surfaces and with an interven'ng air space between the lines of seal. In this manner, the seal is especially effective since, should any foreign matter be able to pass the first line of sealing contact, the-in tervening air space or pocket will serve to destroy the momentum thereof so that passage beyond the` second line of seal is practically impossible.

As apparent from Figure 1, the top and bottom castings on the main or outer door leaves A-A are of considerably greater vertical extent than the castings on the other door leaves B and C, such heavier construction being advisable on account of the greater loads which-have to be sustained by the castings onA the door leaves A-A, it being obvious that each door leaf A is required to susta`n the weight of its correspondlng leaf B or C.

' From the preceding description, it will be seen that, while the door joints are substantially hermetically sealed by compressible rubber sealing strips, nevertheless ventilation is provided to elim'nate or minimize sweating without any dahger of injury to the contents of the container from the elements. Further, the use of castings as described, simplifies and reduces the cost of manufacture since all the so-called necessary fixtures for the doors are incorporated in the castings, that is, the hinge lugs. the Ventilating openings, the locking flanges for retaining the doors closed, the hook lugs for lock'ng the doors to the door framework; and the shrouds for the locking bars. The sheet metal pane's may be sheared and pressed at minimum expense and the assembling of the same together with the edge reinforcing angles is simplified to an ordinary riveting operation.

The invention in its preferred form as applied to doors of the double leaf type has herein been shown and described in detail but it is obvious that many of the broad'features of the invention may be utilized with equal effectiveness in single leaf type doors and also that certain features of the invention may be employed in door structures for other purposes than transportation containers.
