. SECTIONAL CARLOAD CONTAINER A Application fileol'hugust M, 1930. Serial No, 475,39

The object of my invention is to provide a sectional carload container primarily designed for handling wood logs and similar commodities, but its use is not thus restricted. I

Referring particularly to pulp wood logs under the present practice they are'handle to and from a railroadcar individually, which not only increases the cost of the logs 19 but is a slow and tedious method of handling, and it is one ofthe objects of my invention to reduce to a minimum the cost of handling logs in shipment. l I My container is designed to beloaded on railroad cars, preferably of the gondola type, and these cars may have rigid side walls or may, if desired have drop side walls.

Another object of my invention is to provide means for interlocking the containers with thecar to hold them against shifting on the car while in transit. 7

Another object of my invention is to provide a container of such construction that the logs may be unloaded therefrom by gravit In the drawings: Figure 1 is a top plan view of a car with one of my containers on it. Figure 2 is a side elevation of Figure 1 with containers in dotted lines positioned thereon.

Figure 10 is an enlarged detail view of the container door hinge and immediately associated parts. Figure 11 is an enlarged detail. front elevation of the container door connection and joint between the end plates of the container. 555 The container is, preferably, of skeleton form as shown, but in any form it should be open at the top and "have a slat bottom,

the slat or cross beam bottom. preventing the accumulation of waste material in the m secured thereto bymeans of metal plates 17 H0 7 which also function as baclnng plates for the door latch mechanism.

A horizontal steel stiffener 18, of pressed and flanged channel shape extends between the corner posts at a point substantially '75 midway between the end sill 16 and top beam 14 and is securely riveted to each post, the base flanges of the stilfener being dis- .posed toward the inside of the container.

To the inside face of the. corner posts 12 and so 13 ands'ill 16 and beam 14 steel sheathin 19 is attached, applied in two sections wit a lap joint at the pressed steel stiffener 18 as clearly shown in Figure 7 said stiflr'ener 18 functioning as a beam for the end plates. It will be noted from Figure 9 than the outside fianges of-the corner posts are turned outward, and that the inside face of each end wall of the container presents a smooth surface to the lading in the container.

The side construction of thecontainer consists" of a horizontal top beam 20, of commercial angle shape, extending between the corner posts and securely connected thereto by means of metal ssets 21 which also flmcition as lifting 'nki bracltets, to which the lifting links 22 are secured. A similar horizontal cross beam 23 located substantially half way up each side of the container is secured to the corner posts by means of a suitable flat plate and gusset 241. Both

beams

20 and 23 are commercial angles.

Extending vertically between the two

beams

20 and 23 and spaced at regular intervals across the side of the container are pressed, flanged, channel shape braces or slats 25. Each brace laps the vertical flange of the

members

20 and 23 and is securely riveted thereto.

The lower portion of each side of the container, from member 23 to side sill26, serves as a door opening for discharging the lading.

The door for the container consists of a metal frame made up of

commercial angles

27, 28, mitered (preferably) at the corners and connected b suitable gussets 29 (see Figure 11) and ve (more or less) pressed flanged channel shape braces or slats 30 extending vertically between the top 27 and bottom 31 of the door.

The door is provided with suitable hinges 32 secured to the beam 23 and to the top member 27 of the door.

Metal guide shoes 32' are secured to the door frame at each lower corner, said shoes or guides being riveted to gusset plates 33, said gusset plates, when the door is closed, overlap-ping the corner posts and sill 26 and thus functioning as door stops (see Figure 9). Guides 34 are secured to the car walls to cooperate with the guide shoes 32* to hold the containers against shifting on the carp Each container, preferably, is held against shifting independent of any other container on the car.

To each corner gussets 33 is secured a latch hook 37 which projects throu h a slot (see Figure 7) in the outturned ange of each corner post of the container when the door is in closed position. On each end of the container opposite each latch hook 37 a suitable locking mechanism is provided to engage the hook 37 and hold the swinging side doors in closed position.

This locking mechanism consists of a latch 38 operated by gravity, a cam shaped latch pawl 39, and a latch housing 40 for securing these details of the end of the container in proper relation to each other and to the hook on the door.

The door locking mechanism is protected from damage by contact with other containers, by the outturned flanges of the corner posts and by the end gussets 17 to which each locking mechanism 1s attached.

These containers are designed primarily for handling pulp wood logs from a ship to a container and thence by rial to the paper mills.

Generally the loading, handling and unloading operation would be as follows:

. Containers would be lowered into ships hold and the logs thrown into the container and there removed from the car and placed at edge of inclined plane leading to a conveyor. Door latches would then be released,

permitting door to swing outward due to pressure of the lading, and the lading would roll from the container down the incline to the conveyor. The unloading operation could be speeded up somewhat by lifting container by the two lifting links attached to the side of the container opposite'the door to be opened.

This would throw the weight of the lading against the partly opened door, causing the door to open further, would incline the floor of the container, and would hasten the discharging of the load.

The bottom wall of the container is composed of slats 41 secured to the bottom sills 26 by brackets 43 in spaced relation. These slats are of commercial flanged shape. The spaced bottom slats 41 prevent accumulation of waste material in the container and provide for drainage, as this type of container has an open top.
