' momma. (0i. '220"1.5)
This invention relates to material transporting ineans, and is directed more particularly to means for transporting bulk material such as dolomite, cement, grain and the like.
Such means, commonly referred to as containers, are usually of sturdy, metallic, box-like construction. These containers are furnished to the shipper, by whom they are loaded, whereupon they are placed upon trucks and delivered to a public carrier for transportation upon freight cars, boats and the like, to points of destination. The containers may as well be transported upon trucks over the highways. Upon reaching their destination the containers are again transferred to trucks for delivery to' theconsignee. The advantages of this mode of door to door delivery by public carriers are obvious. In the case of shipmentof dolomite to a steel mill, for example, the container may be picked up by a crane and moved to an open hearth furnace where the dolomite may be discharged at a close and advantageous point for use in the furnace. Intermediate movements between a material dump and the furnace are thereby obviated.
tion in handling of the containers. In the past,
by virtue of the container construction then utilized, expensive double drum hoists orflcranes were required forhandling and for' discharge of the contents of the containers, one drum being utilized in elevating the container and the other in releasing; and closing the-*doors for the charge ports. The doors forthe discharge ports,
consequently, required positive manipulation by extraneous means to insure closing of the doors and eliminate the possibility of accidental loading of the containers while the doors are in their open position.
It is an. object of this invention to provide containers, the handling of which shall require only the usual single drum hoist or crane and in which the doors for discharge ports provided in the containers shall automatically assume such position upon the discharge of the material from the containers as to insure automatic locking of the doors upon disposal of the containers upon a supporting surface.
A further object is to provide containers havvation of the containers above their supports.
A further object is to provide containers having vertical doors in opposed walls thereof and carrying locking means directly and automatically engageable with said doors upon placement of the containers upon supports, thereby preventing accidental or unauthorized opening of the doors while the containers rest upon the supports.
A further object is to provide material transporting means having doors in opposed walls thereof and locking means positively actuated into operative relationship with said doors upon seating of the containers upon supports, the construction being such as to avoid modification 'of or addition to the truck, freight car, boat and the like upon which the containers may be shipped. v
A further object is to provide material transporting means having doors in opposed walls thereof, hinged at their upper edges so that their lower edges swing outwardly in the discharge of material from the containers, and locking means carried by the containers adjacent the lower edges of the doors actuated by engagement with supports upon which the containers may be placed into locking engagement with the lower edges of the doors to prevent accidental or unauthorized opening of the doors while the containers are upon the supports, such locking en- --gagement being maintained when the contain-' ers 'areelevated above the supports until released.

5 Figure 3 is an elevation, partly Vin-section, of the container shown in Figure 1, looking toward the left in said figure.
Figure 4 is a horizontal section taken on line 4-4 of Figure 1.
Figure 5 is a horizontal 5-5 of Figure 3.
Figure 6 is an enlarged vertical sectional view I of the lower portion of the container illustrat ing parts thereof in the closed and in the open of metallic.sheets l2 and I3. The sheets-Hare reinforced by means of integral horizontal corrugations l4, while the sheets l3 may advantageously be plain. The container embodies, ad-
ditionally, opposed walls l5-l5 which extend between the opposed walls ll-ll and, together with the latter, constitute a substantially rectangular construction. The walls l5-l5 may 'be designated as adjacent with respect to the walls] l-l l. The walls 15 are substantially similar in construction and'each ,is comprised of sheet metal and providedwith horizontally extending integrally formed reinforcing corrugations l6.
' The walls ll-ll and l5-l5 are secured to-- gether at their adjacent edges by means of vertical comer angles I1. These corner angles extend substantially the entire height of the container. An angle member l8 disposed in parallel relationship to the walls ll-H extends between tainer.
the lower ends of the comer angle members H, as clearly appears in Figure 3 of the drawings. These angle members constitute the bearing surfaces for the container.
The upper margins of the walls ll-ll are reinforced by means of ,angle members Iii-l9 which extend between angle members -20 secured to. the adjacent walls l5-l5 of the 'con- The corner angles I! extend upwardly into overlapping relationship with the vertically disposed legs 2| of the reinforcing angles l9 and the vertically disposed legs 22 of the reinforcing angles 20 and are secured to these legs as by means of rivets 23-23 and 24-24. These rivets,
additionally, are utilized to secure reinforcing castings 25 to the upper corners .of the container.
The container is provided with a roof 25 formed in thepresent instance by means of the metallic end sheets 21-21 and the intermediate sheet 28.
The end sheets are preferably provided with integral stifl'ening corrugations 29, while the intermediate sheet 20 is left plain. The intermediate sheet is overlapped upon the adjacent margins of the end sheets and the joints thus formed are reinforced by'means of angle members 30-30 extending between the walls ll-ll and fastened to the overlapping sheets as by rivets 3|. The ends of the reinforcing angles 30-30 are fastened to the walls I l-l l by means of angle clips 32-32. The roof sheets 21 and 20 are provided with marginal flanges indicated at 33, 34 and 35, these flanges being turned downwardly and fastened to the adjacent walls ,as by means of rivets 36.
The roof or top of the container is provided with an opening 31 through which the container may be loaded. An angle frame '38 is secured to the roof around the opening 3'! and to this frame section taken on line.
is hinged a door 39 adapted to close the roof opening.
Downwardly diverging slope sheets 40-40 extend between the walls Il-ll of the container. The upper margins'of the slope sheets are provided with flanges 4l-4l arranged on opposite sides of'an inverted T-shaped member 42. The flanges 4I-4l are secured to the stem 43 of the T-shaped member which extends continuously between the opposed walls ll-Il. The load which will normally be carried to the T-shaped member by the slope sheets 40-40 is transmitted from the 'T-shaped member to'the walls ll-ll of the container, which are, consequently, reinforced by means of channel-shaped standards 44-44. These standards are riveted to the plain sheets of the walls H-Il as indicated at 4,5. The inverted T-shaped member 43 is fastened to these standards by means of angle clips 46-46 which are riveted to the oppositely extending flanges of the inverted T-shaped member as indicated at 41.
The opposed walls ll-Il extend substantially the height of the container while the opposed walls l5-l5 terminate, as indicated at 48, a substantial distance above the bottom of the container. There is, thus, provided in the walls l5-l5 openings through which the material in the containers may be discharged. The slope sheets 40-40 are inclined downwardly from their securement from the inverted T-shaped member 43 to these openings.
Each discharge opening provided in the walls l5-l5 is defined at its upper end by means of a header 49 secured to the lower margin of the wall I5 andextending substantially continuously across the opening. The lower margin of the discharge opening is defined by means of the lower margin of the slope sheet. The vertical margins of the discharge opening in each wall l5 are defined by meansof cheek plates 50-50.
The header 49 is provided with a vertical flange 5| bymeans of which said header is secured to the wall l5. From this flange the header extends downwardly and inwardly as indicated at 52 and below this portion is formed integrally a substantially J-shaped portion. This latter portion comprises a vertical flange 54, a horizontal flange 55 and a relatively short upstanding outer vertical flange 50, these flanges, as clearly appears from Figure 6 of the drawings, providing a trough 51. Each of the cheek plates 50 is formed with a vertical flange 58 by means of which the cheek plate is riveted, as indicated at 58-A to the adjacent wall H and the adjacent corner angle member II. From this vertical flange 58 a vertical flange 59, disposed at substantially right angle to the first-mentioned flange, .extends toward the opening provided in the wall I5. The flange 59 is provided with an outwardly extending vertical flange 60 which is bent toward the flange 58 in order to provide a short flange 6|. Each-cheek plate 50 is fastened as by means of rivets 62 to the header 49 and to this end the flanges 60 and 6| of the cheek plate are coped so as to terminate below the troughforming a portion of the header 49, as clearly appears from Figure 5 of the drawings. This trough extends above and somewhat beyond the vertical flange 60 of the cheek plate, thereby insuring the drainage of any water which may accumulate in the trough outwardly of the container.
The lower margins of the slope sheets 40-40 are provided with angular copes 63-63, as indicated in Figure 4 of the drawings, in order to permit the extension of the cheek plates downwardly to the desired extent.
The opening thus formed in each of the walls l5l5 isadapted to be closed by means of a door 64. The door illustrated is formed of sheet metal and is provided with integral stiffening corrugations 65. The door 64 is hinged at its upper margin to the header 49, as indicated at 66. It
is to be observed that each door 64 is so hinged as to swing about an axis displaced inwardly relative to the main body. portion of the door. By this relationship the door when swung outwardly is constantly biased toward its closed position. Each door 64 is provided with an upper horizontal flange 61 extending across the trough formed in the header 49 and inwardly-turned vertical marginal flanges 68-68 disposed in overlapping relationship with the flanges BI! and GI provided on the cheek plates 50. This construction of the door 64 provides for weatherproofing of the door and in order to enhance the weatherproofing feature thereof, an angle member 69 is secured to the vertical flange 59 of each cheek plate so that one leg 10 of each of said angle members extends outwardly. An angle member II is secured to each of the inwardly turned vertical marginal flanges of the door 64 and is disposed so as to present an outwardly extending flange I2 lying in overlapping relationship with the adjacent flange 10 when the door is in its closed position.
In this position of the door its lower edge is disposed slightly above an outwardly extending flange 13 provided on an angular member I4 secured to the lower margin of each slope sheet 40.
The flange I3 is formed on a vertically disposed flange I5 of said member. By virtue of this construction escape of the material in'the container when the door is in its closed and locked position is substantially avoided inasmuchas any material which may find its way between the vertical flange 15 and the lower margin of the door will be packed between these members by reason of the provision of the outwardly extending flange 13. There is, thus, afforded a seal preventing the escape of the material within the container and,
in addition thereto, the flange 13 will be effective to prevent rain and other foreign matter being blown upwardly into the container around the lower edge of the door.
The lower margin of the door is reinforced by means of an angle member 16 to the vertical leg of which is secured a plurality of spaced wear plates for a purpose hereinafter indicated.
According to the present invention, means is provided for engaging and automatically locking each of the doors 64 in its closed position whenever a container is placed upon a support. Such means is effective, as long as the container remains upon the support, to prevent accidental or unauthorized opening of the doors and the consequent escape of the material in the container. The construction of this means and its associatibn with each door is such that it' is eflective in conjunction with the pressure of the material within the container exerted against the doors to maintain the doors in their closed position, even when the container is elevated above its support. One embodiment-of such means is illustrated in the drawings. According to this embodiment, a
shaft 18 isprovided, this shaft being journaled tom of a slope sheet, as indicated at 8|. The ends of the shaft l8 eiitend through suitable openings provided in the vertical'flanges 60 of the cheek plates 50. Fastened upon the shaft so as to rotate therewith is a plurality of locking dogs 82, the spacing of these dogs corresponding to the spacing of the wear plates 11 secured to the lower margin of the door. The locking dogs in their. operative position thus engage the wear plates TI. Each of the dogs 02 comprises a substantially solid member formed with a throat 83 within which the lower margin of the door and the vertical flange I5 of the angular member I4 fastened to .the lower margin of the slope sheet are adapted tobe received in the operative position of the dogs in order to secure the door in its closed position. Each of the dogs is formed, additionally, with a hollow boss 84 adapted to be slid upon the shaft 18 and fastened to theshaft as by means of a key 85. The locking dog extends outwardly from this boss in order to provide a surface 86 which is adapted to engage the lower edge of the angle member 8|! when the dog is in its inoperative position to limit rotation of said dog. An operating bar 81 is fastened upon each end -of the shaft 18 in order to permit actuation of the shaft from either end thereof. The upper end of each operating bar 81 is forked, as indicated at 88, so that this end of an operating bar may be engaged by means of a rod, while the container is elevated, to release the locking dogs and obtain discharge of the material from the container. 1
From the foregoing it will be apparent that b virtue of the limiting position of the locking dogs when they are disengaged from the doors 64, these dogs will, upon placement of the container upon a support, be actuated during such placement so as to be rotated into door engaging and locking position. This engagement between the locking dogs and the lower margin of the door is insured by reason of the hereinabove described pivotal mounting of the door. It will be evident, therefore, that the doors 64 wilibeautomatically locked when the container is placed upon a support and be in condition for loading. The doors may, of course, be locked by hand if desired. It clearly appears from Figure 1 of the drawings that in its closed position each door, as well as the operating bars therefor, will lie inwardly of the adjacent corner angles l1 and, hence, be protected by these angles. Moreover, the shaft 18 upon which the dogs are mounted is so disposed as to be protected by the lower margin of the slope sheet and by the vertical'flange 15 of the angular member 14 secured to said margin'of the slope sheet.
The embodiment of the invention illustrated in Figure 'I of the drawings illustrates a'container by the construction of which substantially half of the-contents of the container may be retained therein while the other half may be discharged. A degree of controlled discharge of the contents is, therefore, obtained. In addition, by virtue of this construction, it is possible to transport within the same container two diiferent kinds of materials. The construction of this embodiment of the invention includes a bulkhead 89, preferably terminating somewhat below the roof of the container and secured at its vertical margins to the walls "-4 I, in any desired manner. At its lower margin the bulkhead 89 is secured to the inverted T-shaped member to which the flanges at the ends of the slope sheets 4.0 are fastened. For this purpose the inverted T-shaped member 90 is formed of a pair of angle members 9I-9l arranged in back to back spaced .relationship. Within the space thus provided the lower margin of the bulkhead 89 is disposed. The rivets, by
