21 Claims. (Cl. 105366) The. methods generally in use for handling merchandise freight have not been changed in any essential aspect for a number of years past prior to the adoption by the railroads of the container car of the type invented by Alfred H. Smith, such for instance that shown in his Reissue Patent 16,073, May 19, 1925. Packages of various kinds, shapes and sizes have been and are today delivered to the railroad station and after unloading from shippers truck, are handled by railroad labor and loaded either directly into a car or more frequently placed upon the freight house floor until the car can be loaded, then trucked to and stored in the car. Due to limitations in available extra space, particularly at the larger terminals, the freight must often be loaded into the car currently as offered, which frequently results in an ill-assorted and badly loaded car because it is not possible to reassort and properly load freight by the old method to the best advantage.

The freight thus loaded into a car is transported to destination where it is taken out, placed in the freight house and later on picked up again and taken to the doorway for delivery to the consignees truck. Often, the freight is transferred en route, and intermediate unloading and rehandling being necessary.

The cost of handling 1. c. l. merchandise freight averages 12 to 15 per hundred pounds each at origin and at destination or a total of more than 25 per lbs. of expense, which the railroad assumes for this necessary service at origin and destination ends.

The container may be used in two ways; first, for transportation from one shipper to one consignee, this in cases when one shipper alone has enough tonnage to Warrant using a container; second, use of containers by consolidators who substitute themselves for individual shipper or consignee, and by gathering up large number of small shipments, produce a container load very near the maximum, and act as distributors at destination.

The advantages to the shipper are; saving in total transportation costs, saving in cost of heavy wooden cases, as packing cases are unnecessary when shipments are made in containers; saving in tare; saving incident to practical elimination of theft, damage or other source of loss; saving resulting in faster, better and more eflicient service; and the advantages to the railroad are development and extension of service, having reference particularly to comparatively short haul traflic, saving of freight house labor at both origin and destination, saving of way bill expense; getting greater revenue per car mile incident to heavier loading; saving in equipment; saving from elimination of claims for pilferage and loss; saving resulting from decrease in detention of equipment at terminals; relief of freight house facilities.

' The object of my invention is to make the container car operation as nearly perfect as possible by dividing the car transversely with partitions thus forming container stalls or compartments and having shelves beside these partitions extending transversely of the car to support containers with or without legs, so as to make it possible to run a lift truck onto the car under the container, lift the container from the supporting shelves and remove it to a station platform, truck body or other support. One of the advantages of legs on a container is that the lift truck may be run under the container from any one of four positions and place the container more satisfactorily, making it a much more flexible operation, than if the lift truck could go in from one or two positions and to accommodate the legs of the container I provide the supporting shelves with elongated slots or ways extending lengthwise of the shelf, so that the four legs of the container engaged with the slot will act as safety devices to prevent side sway and decrease to a minimum any possibility of the container slipping off the car. A further object is to provide doors for the ends of the compartment which when in raised position constitute the car side wall; and with these and other objects in view, my invention consists of the parts and combination of parts hereinafter pointed out.

For the purposes of illustrating my invention I have shown a car M of the gondola type divided into compartments l5 by means of the transverse partitions |8, which are provided with container guides II, which center the containers IS in the compartments I5 as they are being loaded and also hold the containers from shifting while en route. These containers are provided with a door or doors l9 of approved type and construction, provided with approved locking bolts 20, 2|, which are connected at their inner ends to a bar 22, keyed to a spindle 23 to which is also rigidly secured the operating handle 24. The outer end of the bolt 20, when in locked position projects through the top of the door into the keeper 25 in the top of the door frame, while the outer end of bolt 2|, in locked position, projects through the bottom stile of the door into a keeper formed in the threshold 26 of the door frame, and is provided with a recess 21 into which one end of the dog 28 is adapted to lock to hold the bolt 2| against operation as will be hereinafter described. In this connection let it be understood that I do not in this application claim the container locking device shown herein, as that forms the subject matter of another application filed by me February 28, 1929, Serial No. 343,353.

On each side of the container compartment I6 I secure to the partitions I6, a container supporting shelf 29 which is preferably hollow or box like and is further secured to the car structure as at 30 as it is preferable that the weight imposed on the shelf be carried by the underframe, although not necessarily. At the ends of each shelf 29 I pivotally mount a container retainer lug or hook 3|, which when in the operative position showing in Figures 4, 6, hold the container from slipping endwise oil the supporting shelf 29. This dog is provided with an arm 32 to which is loosely secured the operating link 33. A link latch housing 34 is secured to the end of the support 29 and is provided with a. recess 35 to receive the link 33. Within the housing 34 is an inclined slide way 36 provided on which a latch 31 is slidably mounted and provided with an operating handle 38 which moves in the elongated slot 39 in the housing. When the retaining lug 3| and link 33 are in the position shown in Figure 6 the latch 31has been moved to lock the link 33 in that position and also lock the lug- 3| in its locked position, whereby the retaining lug 3| is held against movement. To release the lug 3| for the purpose of removing a container, the latch 31 is moved to the left whereupon the link 33 is free to swing or be moved outward and rotate the retaining lug 3| on the pivot 40 to the position shown in Figure 5.

The drop sides or doors 4| are positioned at each end of the compartment I5 and are secured to the car by means of the hinges 42 of any ap- 5 proved type. An extension 43 is hinged at 44 to the top edge of the doors 4| which, when the doors are open, as shown in Figure 9 functions as a runaway for a truck to travel onto the door 4|, and thence into the compartment l5. While the doors 4| are in elevated or locked position across the end of the compartment IS the runway 43 is folded back against the inner face of the door 4| as shown in Figure 4, the door 4| being locked in its closed position by means of 15 hooks 45 pivoted at 46 to the bulkheador partition IS, the hook end embracing the upper edge of the door, and in order to prevent these hooks 45 from jolting out of operative position I provide a. safety catch 41, pivoted at 48 to the bulkhead IS with its forward end abutting the rear end of the hook 45 above its pivot 48. The doors 4|, and runway 43 are provided with suitable bracing angle irons to assist in supporting a load transmitted across them when in the position shown in Figure 9.

Some containers have four legs and in order to make my car universal to containers with and without legs I construct the shelf or container support 49 (Figures 10 and 11) with a slot or passage 50 through which the legs 5| of the container slip or travel as the container is moved onto the support; the braces 52 assisting in supporting the load imposed on the shelf 49. I prefer to make these shelves 49 of such height, that when the 3 container I8 rests on them the legs 5| will be free from contact with the floor of the car. With the legs 5| in position in the slots 50 and the weight on the shelves 49 I find it makes a much better load on the car, and the four legs engaging o with the slots will act as safety devices, to prevent side sway of the container and decrease to a minimum any possibility of the container getting oil the car.

While I have shown the door I9 of the containa ers against the bulkheads and next to the drop side doors, I prefer that all doors face forward in the direction the car is moving, thereby giving absolute protection against pilfering while the containers are on the car. 60

As an additional safety against pilfering I provide the locking dog 28 heretofore referred to, which, when the container is resting on a platform cannot be operated, but which could be operated when the container is supported in the 85 shelves 29 and 49. Therefore I provide a rod keyed to the dog 28 and secured to the other end of the rod a locking dog 53, which when the container is supported on the shelves, comes in contact with the upper face of the shelf, as shown in Figure 9, and so long as it is in that position the dog 28 cannot be operated. As stated this locking feature forms the subject matter of another application filed by me.

In using my invention mixed consignments can 65 be handled from point of origin to numerous destinations ona container basis, rather than box car basis; that is to say, load in one container car six or seven containers, with consignments to separate points so that the container car, when (0 ready to run, would have each container for a different destination, loaded with 5,000 up to 10,- 000 lbs. This would mean that the car would stop at the first destination at which a container is to be removed, and, if there was an empty or u loaded container available. it would be loaded on the car. It will also be obvious that by my invention containers could be left out at the desired stations in the middle of the night with no necessity for the station being open, as they would be locked so long as they'rest on the station platform and the contents fully as safe as would freight in the station warehouse itself. This should mean in actual operation the saving of a very considerable number of box cars, both as to investment, maintenance, operation over the load, yard switching and what is more important, the saving of station house track space, which is often at. a great premium and impossible to increase, except at a prohibitive expense at the-larger terminals.

A still further possible and practical use of this container method would be the practical elimination of the way freight service,- which means that a peddler car is unloaded manually by train crew at the smaller stations. Through the proper complementary trucking arrangements freight could be left at larger stations and trucked to the smaller stations where it would not be good practice to even stop the train, and many smaller stations which do not handle enough freight traflic to pay the cost of operating the station could be closed and at the same time give shippers and receivers at such points improved service, as compared with what they are now getting.
