Woodruff, Bronxville, Y., assignor to The L. G. L. Corporation, a corporation of Delaware Application November 23, 1931, Serial No. 576,925 g ‘ 2 Claims. While I will, for the purposes of illustrating my invention, describe it as being particularly adapt ed for the shipment of lime and cement in bulk, it will, of course be understood that the use of D my improved container is not limited vto these particular commodities. As is well known, cement, prior to my invention, was shipped in bags and each individual bag had to be handled both in loading ‘and unloading on 10 railroad cars and other transportation vehicles, all of which increased the cost of the product. Lime is usually shipped in barrels or in bulk in box cars, requiring considerable handling in loading and unloading, which, likewise, increased “ the cost of the commodity. In both of these methods of shipment there was no real protection against the elements for the commodity because moisture would penetrate the bags, and in the case of box cars a leak in any portion of the car would affect the lime in that particular zone, and this effect would in many instances be straight throughout the entire area of the box car and result in a loss of the shipment. The object of my invention is to provide a con tainer, preferably of less than car load lots size, for the shipment of lime and cement in bulk whereby the entire contents of the container could be handled at one operation, and whereby the commodity would be fully protected against 30 the elements. In instances of large buildings, it is possible by my invention to load the con tainer at the point of shipment and ship the con tainer with its load intact to the point of desti nation and raise the container by a crane, or other 35 means, to the point in the building under con struction and deposit the entire contents at the actual point of consumption in the building, thus eliminating a large amount of manual labor. , Another advantage of shipping cement and 40 lime in bulk is that the percentage of loss in shipment is materially reduced. : With__-these and other ‘objects in view, my invention consists of the parts and combination of parts as will be hereinafter more fully set 45 forth.

The vertical Walls of the container are pref erably made from sheet steel, the side walls 12 being provided with vertically extending ‘corru gations l3 which rigidify and strengthen the walls, the lower portion of the sheet being pro 20 vided with a horizontally; disposed corrugation N. If desired the side walls of the container may be provided With-guide shoes 15 which slidably interlock with corresponding guides secured.'_ to the side walls of gondola cars whereby the con-' 25 tainers are held against shifting on the car, and whereby one or more containers maybe removed from the car without impairing the stability of the other compartments on the car. ' ‘ The end sheets, or walls, [Glare provided with vertically disposed corrugations or rigidifying ele ments ll of varying lengths. - 1 : As shownin Figure 11 the ‘side and end wall sheets are overlapped at the corners and I con nect them by means of ‘an inner post l8 'andan outer post I9, all being suitably secured together by means of 'the rivets‘ 2b.. . Theroof 2| of the container may be of any approved construction and type andis provided with a hatch way 2| (see Figure '7) , andlon each 40 side of the hatch way ,I provide ‘a channel or " other rigidi'fying iron.‘ 22,.-the flanges ‘of which project ‘ downwardly into the container. ‘ This hatch way is further reinforced by angle irons 23 suitably secured. A hatch door 24 having a down wardly extending ?ange 25 around its perim eter is provided with rigidifying beams 26 to one end of which a hinge member 21 is suitably se cured, the other hinge member 2'!’ being secured to the roof 2!] and channel beam 22, as shown in Figure '7. It will be noted that the‘ hinge joint and members are spaced rearwardly from the in— Wardly turned ?ange 25 of the door. At the free end of the door I provide a locking member 28 adapted to engage the screw thread fastening 55 2 2,063,650 bolt 29 which is pivotally mounted at 30 on the car roof whereby the door may be securely sealed in position on the container. It will be seen from Figure 2 that I provide the door with two of the beams 26. The container is provided with lifting links 3| at each corner. The lower end of the container is provided with a pair of doors 32 each having depending ?anges 10 33 around its perimeter, as clearly shown in Fig ure 5. These doors are provided with reinforcing angle bars 34 secured to a door sheet within the ?ange 33, each end of the reinforcing bars 34 be ing provided with an extension 35, which exten ward past the end of each door to the end sill. These housings are clearly seen in Figures 4, 4A and 5. It will be noted from Figure 5 that the lower portion of the chain housings are ?ared to accommodate spread of the chains 40 to their re spective doors. The joint between the top of the chain housing and the roof of the container is closed preferably by welding, or some other ap proved method of sealing the joint against mois ture may be employed.v The de?ectors 39, as 10 shown in Figure 4A, are extended around the chain housing. At any chain hole, or opening, 43 and to one hinge member is secured to another hinge mem ber 31 secured to the side sill 38, the upper end of which member 3'! extends within the ?ange 33 of the door to a point near the underface of the side thereof I provide a drop door chain fastener 44’, the vertical leg of which is provided with a vertical slot 45 which is wide enough to engage and hold the drop door chain when the doors are in closed position, and I also provide on the roof of the container a support 46 adapted to support the hatch door when in open position. The chain 20 fasteners 44’ also function to support the hatch door when it is in open position. While I have shown and described my pre ferred construction, it is, of course, understood that changes may be made in the details of con door sheet whereby this hinge joint is protected struction and arrangement of parts within the against the elements and leakage. I secure a sloping lading de?ector 39 within the container on all four sides thereof just above 30 the top surface of the drop doors, the de?ectors being secured to the side sills 38 of the container base and to the side sheets of the container body, scope of the appended claims. What I claim is: 1. In a drop bottom discharge container side and end sills secured to the bottom of the con tainer and constituting extensions of the walls of the container, a hinge member secured to the end sills with its operative end materially above the lower edge of the end sill, a door having a de 15 sion extends out under the door ?ange, as shown in Figure 4A. These doors must ?t accurately yet operate freely, proper clearances being provided for that purpose. The door is provided with a hinge member 36 secured to its underface and 20 within the depending ?ange 33 and materially above the lower edge of the ?ange 33, which and are preferably mitered at their ends for con nection at corners of containers, the connection being preferably welded. These de?ectors not only function to de?ect the lading toward the door opening, but, as seen in Figure 5, they func tion as a hood or guard sill, cooperating with the top surface of the door to prevent leakage of the 40 lading, and also prevent entrance of moisture into the container. It will be seen from Figure 5 that the end sills elevate the doors of the con tainer materially above the surface on which the container rests whereby the doors are prevented from coming into contact with any wet surface on which the container may be deposited, thus‘ protecting the lading. Suitable chains 40 are connected at their low er ends to the extensions 35 of the door stiffeners, 50 said chains being connected at their upper ends to a common plate 40' which, in turn, is connect ed to the lifting chain 4| having a suitable ring 42 adapted to be engaged by a suitable source of lifting power, said chains 4| passing up through 55 an opening 43 in the roof of the container. To completely enclose the door operating chains, so as to preventltheir contact with the lading, as well as prevent the entrance of mois ture into container a U-shaped chain housing 44 is suitably secured to each interior face of the end wall of the container, and these housings ex tend from the underside of the roof sheet down pending marginal ?ange and hinged to said hinge member at its underside within the space bound ed by the ?ange, said door being positioned when closed in a. plane materially above the lower edge of the end sill, a de?ector extending outwardly from the walls of the container over the joint 40 between the ?anged edge of the door and con tainer to prevent the loss of lading through said joints, a member secured to the underside of the door and projecting outwardly beyond said ?ange, and door closing and locking means secured to said member. 2. In a shipping container designed to dis charge through its bottom, drop doors secured to the bottom of the container locking means for holding the doors in closed position and per mitting them to open, a housing within the con tainer completely housing said means within the container and open at both ends, the lower open end extending below the said doors, whereby moisture in said housing will be discharged 55 through its lower open end outside of the con tainers, stiffeners extending transversely of said doors having extensions extending beyond the edges of the doors to a point under the lower open ends of said housings, said locking means being secured to said extensions.
