Corporation, a corporation of Delaware 13 Claims.

The present'application is a division of my prior application Serial No. 562,372, filed September 11, 1931.

This invention relates to improvements in shipping containers and particularly to containers for container cars of drop-side type and other shipping vehicles.

One object of the invention is to provide a construction of container whereby automobile glass,

automobile parts, and other like articles or commodities may be stored for shipment and shipped in container cars or other shipping vehicles with greater ease, convenience and facility.

Another object of the invention is to provide a container of strong and durable type in which sheet glass or other materials or articles may be compactly packed and secured against shifting and injury while in transit or being handled.

Still another object of the invention is to provide a container in which, by the use of supplemental floors, shelves or partitions the glass or other commodity or articles to be shipped may be stored in tiers therein and the tiers of material separately secured and held against shifting movements.

Still another object of the invention is to provide a container in which a removable supplemental floor, shelf or partition of sectional type is provided so as to allow greater convenience of access to the container for the packing of goods therein or the removal of goods therefrom.

With these and other objects in view, the in- 40 the container. 1

Figure 3 is a vertical front-to-rear section through the container on the line 6-t of Figure 2.

, Figure 4 is a detail view showing a feature of 45 construction. 7

Figure 5 is a horizontal front-to-rear section through one side of the container on the line l-t of Figure 3.

Figure 6 is a horizontalsection through'the container on line 8--8 of. Figure 2.

Figure 7 is a horizontal section through the container on line 9-9 of Figure 2, a portion of the lower floor being broken away to expose the bottom frame construction.

Each container! is of rectangular or oblong rectangular form and of special construction, and comprises a steel-framed, steel-sheathed waterproof container provided with depending supporting legs 8 at the four corners of the bottom thereof, lifting brackets 9 at the four corners of the top thereof, and hinged doors It at the front, which doors are adapted to be secured in closed position by a vertically disposed, oscillatory looking bar ll mounted on one of the doors and carrying at its ends bolts i2 to engage keepers E3 on the container above and below the doorway. Any suitable means may be employed for oscillating the bar H, a hand lever M being shown in the present instance as provided for that purpose, said lever being also apertured to serve as a locking staple for engagement with a keeper eye it: on the other door. A hook l6 carried by one end of a chain l'i fastened at its opposite end to the door carrying the keeper eye is shown as provided for engagement with the eye to hold the staple in looking position, but a padlock or other locking means may be employed for the purpose, and, if desired, a suitable type of seal may be used which must be broken before the doors can be opened to allow access to the container, and the breakage of which willindicate that the fastening means has been tampered with or released.

The legs 8 are adapted to seat within receiving sockets I8 provided for their reception in the floors of the compartments. The legs 8 are provided with guide shoes It for guiding contact with the doors and other surfaces of the container compartments of the car in guiding the containers into and out of position, and the sides of the containers may be provided with suitable reinforcing and guiding ribs 20 for engagement with suitable guides at the sides of each compartment of the car to further assist in guiding the container into and out of position.

The container 1 is provided with a permanent bottom floor 29 and may be provided with an upper floor or horizontal shelf or partition 30 in the event that it is desired to divide it into two superimposed storage compartments. In the present instance an upper floor or compartment 3% is provided which is removably supported on angle metal brackets or ledges 3i and is divided transversely into front and

rear sections

32 and 33 for greater convenience in loading and unloading the container, as, upon the removal of the partition section 32 through the doorway, easier access to the interior of the container is allowed for loading and unloading the lower compartment and loading and unloadingthe goods supiported on the inner or rear shelf portion 33. flhen it is desired to pile the goods solidly from the floor 2 to the maximum loading level of the container the shelf 30 may be dispensed with, but its use allows desirable separation of different kinds of material, as well as the packing or storage of materials of the same character in a better manner and to better advantage from the standpoints of ease and convenience in loading and unloading and greater security against damage of the lading.

One object of my invention is to construct the container so as to allow packing of the lading in tiers, and the packing and shipment in a secure manner of automobile window or windshield glass or other sheet material or other articles or goods which may be packed in the same or a similar way. As shown, each compartment of the container above and below the partition 39 is provided at one side with an abutment 34 which is inclined slightly to the vertical, and at its opposite side with a straight vertical abutment 35, said

abutments

34 and 35 being formed by battens which are secured to supporting

beams

36 and 31. In loading glass or other sheet material, or similar material, in the upper compartment or lower compartment, the glass sheets 38 are disposed vertically with their lower longitudinal edges resting on the floor 29 or partition 39, as the case may be, the first sheet being rested against the abutment 34 and the other sheets successively placed in position, with sheets of paper or other cushioning layers 39 therebetween until a space between the final sheet and the abutment 35 is left sufficient to receive a clamping wedge 40 which is inserted in position between the last sheet and said abutment S5 to clamp the stack of sheets in parallel relation and against shifting laterally of the container. Preferably the container is also provided with means for engagement with the end edges of the sheets to prevent the stack of glass from shifting either forwardly or reawardly, The means provided for this purpose comprises a stationary clamping bar ll at the front of each container compartment, which bar rests upon supporting blocks 32 at the opposite sides of the container doorway, and a cooperating movable clamping bar or block 33 resting at its ends upon guide blocks M arranged at the opposite sides of the container in alinement with the blocks 42. The bar or block 43 is engaged by feed dogs 35 provided with clutch pins 46 for engagement with notches M arranged at intervals in feed bars one of such bars being provided at each side of the container, and each bar being coupled at its forward end by a swivel connection 48 with a feed screw 49 journaled in the block 32 and having an angularend 48 extending outwardly at the front of the container for the application of a hand crank or other suitable tool thereto, whereby the shafts associated with each movable clamping bar d3 may be revolved to move the feed bars 55 and the clamping bar 53 forwardly to bring said bar 43 into engagement with the rear edges of the sheets and to force the front edges thereof into clamping engagement with the bar ll, by which means the stack or sheets of glass will be held from shifting either forwardly or rearwardly. The battens 34 are cut away for a portion of their length along their lower edges so as to form slotted guideways 5% between the same and the bars Mi into which the bar &3 may move to clamp'stacks of less depth than the depth of the container compartment or of varying depths, allowing small, large or intermediate stacks to be clamped with equal facility. The dogs 45 are tiltably mounted so that their clutch pins 40 may be disengaged from any of the notches 4'! with which they are engaged at any time and shifted forwardly or backwardly on the bars 45' to regulate the distance between the bars 4| and 43 as may be required in clamping stacks of different sizes, and which capability of adjustment of the dogs 45 and the bar 43 allows adjustment of the bar 43 to clamp small or large stacks without an excessive range of travel of the bars 45 or of feed screws 49 of excessive length being employed. The construction and arrangement of parts in the container, furthermore, adapts stacks of glass or other material to be stored in tiers in the container and each tier to be clamped firmly and securely against movement either forwardly or rearwardly or sidewise or in any direction in the container, so that damage to the material being shipped will be effectually prevented. It is, of of course, obvious that sheet materials other than glass may be shipped and materials other than sheet materials may be stored and shipped in the containers in tiers or en masse, so that a container suitable for shipping goods in either of these ways is provided.

The meeting rails 58 and 59 upon the free edges of the doors are preferably provided with beveled surfaces.

From the foregoing description, taken in connection with the drawings, the construction and mode of operation of the invention will be readily understood without a further and extended description, and it will be seen that the invention provides a construction of container which allows glass or other sheet material or automobile or other parts of various kinds to be stored and shipped with great ease and facility and allows material of the same kind or different kinds to be shipped for delivery to the same or different destinations. These containers are also so constructed that different kinds of materials, or different lots of the same material, may be stored and shipped in each container and the lots kept separate from each other, while aifording greater convenience in storing and removing the lots of goods. Other advantages of the invention will also be understood and appreciated by those versed in the art.

While the constructions of the parts herein shown are preferred, it is to be understood that changes in the form, proportion and details of construction of the parts may be made, within the scope of the appended claims, without departing from the spirit or sacrificing any of the advantages of the invention.
