means to as great a degree as possible.

This problem is recognized in the many patents granted to the late Alfred H. Smith,

. as for instance in his Reissue Patent No.

16,073 of May 19, 1925'. L

The object of my invention is to provide a container car to handle interchangeable containers of the type shown in the said Smith patents, but other types of interchangeable containers may be handled without departing from the spirit of my invention.

According to my invention I provide the car with a plurality of bulkheads disposed transversely of the car and extending from side to side of the car, thereby forming a plurality of container stalls open at each end, so arranged as to facilitate loading and unloading of the containers at points where special facilities, such as overhead cranes, are not provided for this purpose, there being sections swingingly mounted to each side of the car, one for each end of each stall, said sections while in elevated position functioning as barriers at each end of each stall, and

when in lowered position serving as gang- Ways bridging the space between the side of .the car and the freight platform, over WhlCh the containers may be moved to and from the stalls without the use of cranes. Mea1 1s are provided to securely lock the sect1ons 1n their elevated positions so that they function as barriers at each end of the stall to prevent the ?containers accidentally moving out of their stalls, thereby eliminating the poss1b1lity of their slipping off of the car or extending beyond the car outline while in transit, thus obviating all danger, wrecks, or s1deswiping of other trains.

view.

The reference numeral 6 designates the underframe of a car of any approved construction mounted on suitable trucks 7.

According to my invention the cars are equipped with bulkheads 8 extending transc, L. con- Figure 6 is an enlarged detail sectional treme ends of the bulkhead I provide angle irons 10 which constitute material abutments for the drop side sections to which I will hereinafter refer. These bulkheads divide the car into a series of stalls or sections each adapted to receive and hold while in transit a container 11, which container may be of any size desired that will fit in the stalls. It is, of course, obvious that the containers may be made in multiple, that is to say, a numher of small containers may be placed in each stall.

The car is provided with a plurality of drop side sections 12swingingly mounted to the car structure, one adjacent each end of each stall, as shown in Figures 1 and 2, said sections when in their elevated position functioning as barriers, or bulkheads at the ends of each container to prevent the accidental displacement of a container while in transit thereby eliminating the possibility of a container projectingbeyond the sides of a car and sideswiping another train, and also prethe side sections in loading and unloading the containers to and from the car. The drop side sections are provided with locking bolts 15 which are pivotally connected to a central link 16, which link in turn is pivotally mounted on the drop side 3 section and is operated by means of a handle 17. The outer ends of the bolts 15 project through elongated openings 18 near the ends of the drop side sections as clearly shown in Figures 1 and 2, the portion 19 of the bolt at the end being spaced back from the inner face of the drop side section so that it is adapted to engage beyond the angular abutments 10 at the ends of the bulkhead, thereby locki-n the section in its elevated position; As 'a' ditioual guarantee for maintaining the drop side sections 12 in their elevated position, I pivotally mount a hook 20 at each end of each bulkhead 8, which hook is adapted to be moved over into engagement with the top portion of the drop side section, as more clearly illustratedin Figure 3. An apron 13" is connected by means of hinges to the top edge of the drop side sections 12 and is adapted to fold inwardly against the inner face of the drop side section when the section is in its elevated position. When the section is in its lowered position, as illustrated in Figures 3, 4 and 5, this hinged apronis extended, as shown in these figures and forms a continuation of the drop side section, the apron 13" being-inclined as shown. When the drop side section is in its lowered position, as shown in Figures 3, 4 and 5, it functions as a gangway between the side of the car and the station platform over which the containers may be moved to and from the car.

I prefer to have the bottom wall of the container, when loaded on the car, in its stall elevated above the floor of the car so that the platform of an electric truck or other conveyance may be run on the car under the contamer, such trucks being well known and provided with means whereby their platforms may be raised after they-are under the container and thus raise the containers from the truck, or other conveyance may be run underneath it, as above described. In case there are containers to be handled that are not provided with supporting legs 21, I may provide the car with supporting blocks 22 at each corner of each stall which will support the plontainer with its bottom wall above the car oor.

The bulkheads 8 and the drop side sections 12 function to prevent the containers from shifting laterally or longitudinally on the car, and the removal of one container from a car does not reduce the stability of the remaining containers on a car because each container is provided with its particular bulkheads.

- I may provide at each corner of each stall a floor socket 23 to receive the legs of the containers and thereby add security against the shifting of the containers on the car while in transit. These floor sockets may, as illustrated in Figure 4, at 24 project above the car floor, or, as shown at 25 in Figure 5, they may be sunk into the car floor. However, the mainstay or bracing against the shifting of the containers on the car resides in the bulkheads 8 and the drop side sections 12.

In the case of containers made without legs it is obvious that at stations there will be provided suitable supports similar to the supports 22 on the platform of the station upon which to raise the containers with its bottom wall elevated above the station platform so that the electric truck, or other conveyance can be run under the container and raise it for transportation to its stall on the car.

As is well known, it is becoming more and more the practice of railroads to ship goods in containers after the system set forth in the Smith patents, above referred to, and my im proved car is designed to receive and transport these interchangeable containers and andle these containers at stations where there are no crane facilities for lifting them. Of course, the car is designed for through traflic as well as local traffic, and as the containers' are built to a certain standard my improved car is built to that standard and the stalls are adapted to receive a single container or multiples of that size container.

The end edge portion of the drop side sections, when in elevated position, have a firm abutment a ainst the angle irons 10 at the end of each bull: are also provided at their upper edge with an angle iron 26 which rigidifies the upper edge of the section and functions as a support when the section is lowered to serve as a gangway as clearly illustrated in Figures 3, 4 and 5.

As stated, my improved drop side container car and sectional carload containers are so arranged as to facilitate loading and unloading of containers at points where special facilihead. These side drop sections ties, such as overhead cranes, are not provided the underframe thereby dividing the car into a plurality of stalls open at each end, at both sides of the car, a plurality of side sections swingingly mounted to the car one at each end of each stall, said sections when lowered being adapted to serve as gangways, a locking means carried by each side section adapted to interlock with the ends of the bulkheads to hold the sections in raised position.

2. In a car of the class described, the combination with an underframe of a plurality of bulkheads extending from side to side of the underframe thereby dividing the car into a plurality of stalls open at each end, at both sides of the car, a plurality of side sections swingingly mounted to the car one at each end of each stall, said sections when lowered being adapted to serve as gangways, a locking means carried by each side section adapted to interlock with the ends of the bulkheads to hold the sections in raised position, and a safety catch on the ends of the bulkhead adapted to hook over the top edge of the sections.

3. In a car of the class described, the combination with an underframe of a plurality of bulkheads extending from side to side of f the car thereby dividingthe car into a plu;

rality of stalls open at each end andtransversely disposed of the car, container guides on each side and at each end of each bulkhead, a plurality of side sections swingingly adjacent each end of each stall, an apron hin ed to the to of each section and adapted to old in on t e inner face of its section, andan angle'iron secured to the outer face and at the top of the section designed to rigidly support the top edge of the section when the section is functloning as a ramp.
