20 Claims.

This invention relates to improvements in transportation containers, andmore particularly that type of transportation container known as railway containers.

In the transportation of merchandise and other freight in so-called less than carload lots, by truck, railway and/or boat, the merchandise is placed in closed metal containers having pivoted doors on opposite sides thereof, which doors are then locked and sealed and transported from the source of Origin to the consignee. Such containers are most frequently assembled on at cars in groups and are subject to all kinds of weather conditions so that adequate provision must be made for weather-sealing the several joints around the doors in order to prevent damage or injury to the contents while being transported.

Heretofore, two general methods have been employed to seal the door joints. One of such general methods utilizes rubber sealing strips or gaskets in or along the several door joints and the other general method utilizes spring pressed wooden strips beneath layers of canvas, felt and/or other fabric.

Experience has demonstrated that both of the or seals soon deteriorate, thus necessitating re-l placement with its attendant expense. In the case of spring pressed packings, the wood backingstrips soon dry out and become warped and the wear on the fabric is quite rapid. The spring pressed packings are also open to the objection that considerable power is required in closing and opening the doors because of the resistance that must be overcome in compressing the packing.

Still another objection inherent in the foregoing described types of sealing arrangements in the case of transportation of certain commodities, is that the sealed joints, when effective, are air tight so that air circulation to the interior of the container is prevented and hence sweating" is induced.

One object of this invention is to provide a transportation container economical to manu-v facture and maintain and wherein the joints around the doors are effectively and efficiently sealed against the weather without the use 0f teel 1932, Serial No. 585,708

rubber gaskets, spring pressed' packings or like attachments subject to deterioration.

Another object of the invention is to provide a transportation container having pivoted doors wherein the weather sealing of all the vertical door joints is obtained by means ofY freely interlocking parts, integral or fixed with respect to the several door framing elements and doors proper.

Another Object of the invention is to provide a transportation containerof the typeindicated, wherein the joint along the tops of the doors is effectively weather sealed by means Of an automatically functioning sealing hood or flap.

A further object of the invention is to provide a transportation container wherein the foregoing objects of invention may be attained in connection with doors of either the single orso-'called double or foldingleaf type.

Still another object of the invention is to provide, in -a transportation container, simple, eilicient and relatively inexpensive means for locking and sealing the doors in closed position, which means require manipulation of only a single member with a minimum number of movements to effect closure, locking and release of all the doors and applicable to either doors of the single or so-called double or leaf type.

Another object of the invention is to provide a transportation container with joints around the doors such that, while completely effective to seal the same against admission of rain, snow, sleet or the like, it at the same time allows of air passing through the joints in order to prevent sweating.

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

In the drawings forming a part of this specification, Figure 1 is an end elevational view of a transportation container of the railway type, showing the improvements in connection therewith, parts being broken away to better accommodate the view On the sheet and a portion of the pivoted hood or lintel being broken away to illustrate certain of the parts.

Figureisa vertical, sectional view, upon an enlarged scale, corresponding to the section line 6-6 of Figure 1. Figure 7 is an enlarged, vertical, sectional view corresponding to the line 7-7 of Figure 1. Figure 8 is a detail view corresponding to Figure 2, showing a modified form of a weather sealing flange.l Figures 9 to 15, inclusive, are views similar to Figures 1 to4 7, respectively. illustrating an other embodiment. of the invention,'ligure 10 corresponding to the section line 10-10 ofk Figure 9, Figure 12 to the section line 12-12 of Figure 11; Figure 13 to the section line 13-13 of Figure 11 and Figures 14 and 15 corresponding to the section lines 14--14 and 15-15, respectively,

` of Figure 9. In Figure 9, parts of the container surro 'ng the door structure have 'been omitted in orde to permit illustration upon a somewhat larger scale.

Refening first to the construction illustrated in Figures 1 vto 7, the container is shown as having an end wall 20 in which the door arrangement is provided, it being understood that a duplicate arrangement will ordinarily be used on the opposite end of the container.` The corner posts of` the container are indicated at 21-21, the roof at 22, crane hooks 23--23 at the upper corners thereof and crane loops 24--24, two or more on each side at the rooi'. As will beunderstood, the side walls of the container may be suitably braced to provide the necessary rigidity as by vertical corrugations 25-25.

Each door opening is defined by a top plate 26, which functions as the side or end plate of the container, the same being oi generally Z-formation with an upstanding flange 27, to which the roof sheets are secured, and an inwardly offset. depending flange 28 constituting the lintel oi' the door framing. The side posts of the door opening framework are defined by members. 29 oi' generally channel formation. having one leg thereof elongated, as illustrated Ibest in Figure 2.V

The bottom of the door opening is defined by a sill 30 of channel formation, as shownin Iiigure 7, that portion of the sill corresponding to the' width of the door being inwardly offset from the remaining end portions of the sill, indicated at 30e.

between which and the sill is interposed a door Secured to the sill is a threshold angle 31 sheet 32 and on top of which lie the floor boards, indicated at 33. Secured to each of the postsl 29, in the construction shown, is -a channel 34 facing inwardly toward the door opening and constituting what may be termed the jamb of the door frame. l

In the arrangement chosen for illustration, the door opening 'is closed by two doors A and B, each of which in turn is comprised of two leaves,

those of the door A being referenced 35 and 36Y and those of the door B as 37 and 38. The doorsv are mounted on sets oi' double hinges 39-39,

fastened to,l Ithe post.29 so as taper-mit the outer leaf of each door to swing back yupon its inner leaf and still swing clear of the post 29 and be,

folded back against the wall of the container, as

' will be understood. The two'leaves of each door are pivotally connected as by the hinges 40-40. Each door, as shown, may be said to comprise a main sheet metal portion or panel with reinforced edges, the edges being varied somewhat on the individual leaves in order to conform to the corresponding adjacent members with which the weather seal is to be effected. Considering first the door leaf 37, the same comprises a main sheet metal panel 41 of suitable gauge, which is inclined outwardly along each of its vertical edges, as indicated at 42-43, and thence has its marginal portions extended parallel to the main plane ofthe door, as indicated at 44-45. Between the inclined portion 42 and 43, the panel may be suitably reinforced by integrally formed horizontal corrugations 46. Secured to the inner sides of the flat marginal portions 44' and 45 are preferably formed channel shaped reinforcements 47 and 48, respectively, the channels facing toward the edges of the door, as clearly shown in Figure 2. To the lefthand edge of the door 37, as viewed in Figure 2, is secured a combined bracing and bridging strip or plate 49 for the full length of the door, the same being riveted to the main panel sheets, as indicated at 50, and to the inner flange of the channel member 47, as indicated at 51. Said plate is extended beyond the edge of the door so as to provide a weather sealing fiange 52, which is inclined outwardly and away from the door and adapted, when the door is in closed position, to extend within the corre' will be offset, as indicated at 56-56, a. dis-' tance corresponding to the thickness of the bridging plates 49 and 53 so as to obtain a substantially flush surface.

Referring now more particularly to Figures 6 and 7, the main panel 41 of the door 37 is inclined outwardly and away from the center of the panel' f at the top and bottom edges, as indicated at 56 and 57, respectively, the sheet then being continued to provide vertically extending at marginal portions 58` and 59, respectively, at the top and bottom and to the inner sides of which are secured angles 60 andl 61, respectively. The angies 60 and 61- will be extended tothe vertical margins of the door over the top and bottom ends, respectively, of the side edge constructions. As will be understood, the door leaf 35 will bev made similar to the door leaf 37 and detailed description thereof is not deemed necessary.

' The door-leaf 38 has its lefthand edge, as viewed in Figure 2. constructed similar to that of the lefthand edge of the door leaf 37 and the same will be true of the righthand edge of the door leaf 36, as viewed in Figure 1. The righthand edge of the door leaf 38, since it is formed to provide a housing for the operating shaft, is of special formation, as shown in Figure 2. Instead 47 or 48, the bridging or bracing plate 62, which is secured to the main panel at 63, is extended parallel to the main panel for a distance, is then extended outwardly at right angles, as indicated at 63, thence parallel withthe outer marginal flange, asr indicated at 64, and beyond the marginal flange, and thence is bent inwardly at right angles, as indicated at 65, and terminates in a narrow inner edge flange 66. The main panel sheet and section 64 of the edge reinforcement are secured byv rivets 67.

'I'he free edge of the remaining door leaf l36 is formed similar to the righthand vertical edge of the leaf v37, except that the bridging strip or plate at 69, and is thence bent outwardly at right angles, as indicated at 70, so as to provide a flange which enters the channel or trough-like free edge of the door B.4 As will be understood, the top and bottom edges of the door leaves 36 and 38 are formed similar to the top edges of the other leaves 35 and 37.

With the construction shown and so far described, it will be seen that at each vertical joint between the doors and jambs, between the leaves of each door, and between the meeting edges of the two doors, there is provided what may be termed a channel or trough-like construction on one member and an extended flange on the corresponding adjacent member, which is adapted to enter the channel or trough-like formation when the doors are in fully closed position. It will further be evident that any rain, snow or sleet which may be driven through the cracks or joints, will strike against a flange or section and thereby be deiiected more or less outwardly and its momentum destroyed so that it will not pass the seals provided by the cooperating edge structures. At the same time, while the joints are weather sealed as against the admission of rain or other foreign matter, nevertheless air may circulate to a limited extent between the interior and exterior of the container, thus preventing sweating.

Referring more particularly to Figure 7, it will also be noted that an effective seal has been provided at the bottom edges of the doors. Secured to the sill 30 is a horizontally disposed angle 71 having its upper flange arranged horizontally and extending outwardly, as indicated at 72, which, when the doors are in closed position, is slightly spaced below the horizontal flanges of the bottom angles 61 of the doors, the latter in turn being disposed below the floor level. With this arrangement, any foreign matter driven inwardly below the edges of the doors, will first be deflected by the angle 71-72 and even though some of the foreign matter may pass the joint between the flange 72 and the depending flanges of the door angles, its momentum will be sufficiently destroyed so that it cannot pass upwardly between the bottom door angles 61 and the threshold angle 31.

To provide the weather seal for the top edges of the doors, the following arrangement is employed. Secured to the lintel for the full length thereof is a plate 73 (see Figure 6) which extends downwardly below the web section of the side plate and is first outwardly offset, as indicated at 74, and thence bent inwardly as indicated at 75. Pivotally mounted on the door posts at each of its ends, as by brackets 76 having pintles 77, is a hood or deflector plate 78, which extends upwardly behind the plate 73 where it has an outturned flange 79 and which is extended down below the top edges -of the doors and terminates in a downwardly and outwardly inclined flange 80. Said hood plate 78 normally hangs in the position shown in Figure 6 under the influence of gravity, but is adapted to be swung outwardly about its pivot 77 when any one of the doors is opened. As clear from Figure 6, any rain or other foreign matter which may be driven inwardly below the flange may pass the joint between it and the hood plate 78, but its momentum will be sufficiently destroyed in the pocket above the flange 75 so that it will not pass over the flange 79. `Similarly any foreign matter driven horizontally against the door below the shedding flange 80 will strike the door panels and be deflected outwardly and the momentum sufficiently destroyed so that it cannot pass up through the relatively wide joint between the hood plate 78` and top marginal portions of the doors.

To lock or latch the doors in closed position, the following arrangement is employed. Referring to Figures 2 and 6, the door leaf 38 is provided at the top thereof at its inner or hinged edge, with a bracket 81 of generally angular formation, as viewed in Figure 6, the depending flange thereof being riveted to the top edge of the door construction, as indicated at 82. The horizontal flange of said bracket is extended inwardly beyond the inner face of the door and at its inner end is formed with a lug or hook 83, which is adapted to enter through an opening 84 provided therefor in the depending flange of the top plate or lintel 26. When the door leaf 38 is in fully closed position, as shown in Figure 2, said hook or lug 83 engages behind the lintel and hence prevents the door from opening outwardly at the pivot joint between the leaves 37 and 38. As will be understood, a corresponding arrangement is employed at the upper. end of the door leaf 36. At the bottom and also adjacent the pivotal connection thereof, the leaf 38 is providedwith a corresponding bracket 85 of angular form, the vertical flange of which is riveted to the 'lower edge of the door, as indicated at 86, and the other horizontal flange of which is formed with a hook or lug 87, which is adapted to enter through alined slots 88 forme'd in the sill 30 and the depending flange of the angle 71-72, as shown in Figure 7. In this manner, the bottom of the door will be latched against the sill and prevent opening movement thereof unless and until the leaf 38 is first swung about its hinges 40. The outer leaf 36 is similarly equipped with a lower latching hook, as will be understood.

At the free vertical edge of the leaf 38, which is closed last and overlies the leaf 36, there is rotatably journaled in the inwardly facing channel formation, an operating shaft 88 of prefer ably hollow, tubular formation for the greater part of its length and having secured thereto at its upper and lower ends crank arm castings 89 and 90 respectively. The shaft is journaled in suitable bearing openings provided in the top angle 60 and bottom angle 61. Each of said castings 89 is formed with a crank-like hook shaped arm 91--91, which are adapted to enter through corresponding slots 92 and 93 provided in the lintel and sill respectively so that, when the doors are fully closed and the shaft rotated to the position best indicated in Figure 5, said hooks will engage behind the lintel and sill and thus hold the doors closed. For operating the shaft at a convenient level, the lower casting 90 is formed with an extended arm 94, which is also adapted to act as a hasp, the same being slotted as indicated at 95 to seat over a staple`96, through which may be inserted a retaining pin or the like in the holes 97 provided therefor. Preferably, all of the upper hook shaped lugs or arms for latching the doors will be protected from the lading by suitable housing castings 98 riveted to the inner face of the depending flange of the lintel or side plate. In this connection, it will be observed that the operating shaft is housed from the weather due to its location within the channel formation at the free edge of the door B and is likewise effectively protected against injury. i

In the modification shown in Figure 8, the weather sealing anges carried by the lefthand edges of the leaves 37 and 38 (and similarly the the free edge 352 of the flange toward the crackv and hence reduce still farther the possibility of any of the foreign matter passing over the edge of the ange to a position behind it.

Referring next\to the construction illustrated in Figures 9 to 15, the general arrangement is the same that for the construction already described. As before, two doors A' and B' are emv ployed, each consisting of two pivotally connected leaves, as indicated at 135, 136, 137 and 138, respectively, and hinged in the same manner as previously described. To the side door posts 129 are riveted vertically extending formed sheet metal jambs 134, each of which diii'ers, however, from the Jambs 34 by having an additional inwardly extended inner flange 234, thus still preserving the general channel or trough-like formation but with a somewhat narrowed opening or mouth, as will be clear from Figure 10.

The door leaf 137 consists of a main sheet metal panel 141, the main plane of which is disposed outwardly instead of inwardly, as in the first described construction. Along its vertical edges, the panel 141 is formed with inwardly extending inclined sections 142-143, terminating in inner flat marginal sections 144 and 145, respectively. To these edge portions of the sheet metal panels are secured edge bracing plates 148 and 149, each of which is of generally z-section, the outer flanges of which are riveted to inwardly offset portions of the panel, as indicated at 248 and 249 and the inner ilanges of which are secured to the flat margins of the panel by rivets, as indicated at 151 and 155, respectively. The lefthand edge brace 149 is continued and has integrally formed therewith, the weather sealing flange 152 so arranged that it isadapted to enter through the mouth of the jamb strip 134 when the leaf 137 is swung about its pivotal axis. In this construc-- tion, as shown in Figure 10, any rain or otherforeign matter driven between the flange 234 and the member 149 must first be deflected at right angles and then will be again deflected by the inclined flange 152 and its momentum destroyed -so that danger of the same passing around the free edge ofthe flange 152 is eliminated. As will be understood, the door leaf 135 will have its outer hinged edge similarly formed to cooperate with a similar jamb 134. At its free edge, the leaf 137 has an additional weather sealing member 448 applied thereto, which is of channel or U- section facing inwardly and riveted to the member 148 as by the rivets 348, thus forming a channel or trough formation with a somewhat narrowed mouth similar to that of the jamb 134.

The top of the leaf 137 is formed by extending the sheet metal panel 141 inwardly and upwardly, as indicated at 156, which terminates in a vertical marginal iiange 158, to which is riveted, on the outer side thereof, an angle 160. The lower edge of the door, as shown in Figure 15,*is similarly formed by extending the panel inwardly and downwardly, as indicated at 157 and terminating the same in a flat marginal flange 159 to the outer lleaf 137.'1Along its free or righthand vertical edge, as viewed in Figure 10, the leaf 138 has secured thereto a specially formed reinforcing section 163 providing an' outwardly facing channel 263 and an inwardly facing channel 363. 'I'he channel section 263 provides a recess for accommodating the vertically extending operating shaft 188 corresponding to the shaft 88. 'I'he free edge of the leaf 136 has a reinforcing member 169 secured thereto, so formed as to present an outwardly facing channel 269, the flange 369 of which enters the inwardly facing channel 363 of the adjacent door and within which channel 269 is received the inwardly extending flange 463 thereof. With this construction, the door B', when closed, securely retains the door A and a double Joint weather seal is provided between the interiitting channel formations at the free edges thereof, shown in Figure 10.

At the Vtop and bottom thereof, each leaf 138 and 136, adjacent its hinge connection, is provided with latching brackets 181 and 185 corresponding to the similar brackets 81 and 85, respectively, and adapted to engage the lintel and sill, respectively. The operating shaft 188 is similar to that previously described except that the upper casting 189 is provided with an additional lug or kicker 289 (see Figure 13), which is adapted to engage and push out the pivoted hood 178 in advance of the actual opening movement of the door. 'Ihe pivoted hood 178 is mounted and functions in the same manner as the hood 78 except that the same is formed with a right angular flange 180 at its bottom edge instead of an inclined flange 80.

From the preceding description, it will be ob-l served that enective weather seals against the admission of any foreign matter are provided between all vertical joints and also along the top and bottom edges of the doors, said weather sealing formations being further characterized by the fact that they will permit circulation of air to the interior of the container. All the formations, as obvious, are of metal, thus doing away with 'all rubber, fabric and springs for such purposes as heretofore employed. It will also be noted that all edges of the doors are thoroughly reinforced and braced against collapse or twisting and that, with respect to all vertical edges of the doors, a tubular formation is present whereby great strength per unit lof weight of material is obtained.

The invention has been shown and described in what is now considered its preferred form but obviously various changes and modifications may be made without departing from the spirit of the invention, and all such changes are contemplated ascome within the scope of the claims appended hereto.
