9 Claims. (Cl. 114-72) The invention relates to a container ship capable of storing package freight containers in one or more holds and has reference in particular to an improved construction of container ship having fixed beams in the holds for supporting less containers for the same, thereby making it possible to transport such miscellaneous freight from any shipping point to its destination without rehandling, repacking or crating that would otherwise be necessary. The containers are of standard size and a convenient number may therefore be carried on any conventional railroad at car. This permits the containers to be initially loaded by the manufacturer or shipper, sent over the railroad to the loading terminal for the container ship, and stored in the ship in a manner requiring the minimum of time, eifo-rt and space, with the result that intermediate handling [of the individual packages is entirely eliminated.

Another object is to provide a container ship having fixed beams in one or more holds and by substantially eliminating the top deck large open hatches are formed so that ready access may be had fior placing the package freight containers in position on the beams or for removing the containers therefrom. i

A further object of the invention is to provide a container ship having fopen fixed beams for supporting a pluralityof package freight containers within one or more holds of the ship and which beams will be notched for receiving lthe containers in a manner to securely lock them in place.

A further object is to provide a container ship having one or more holds equipped with container supporting beams of special notched arrangement and forming different levels within the hold with the beams alternately extending longitudinally and transversely as regards the different levels.

With these and various other objects in, view,f

2 the invention may consist of certain novel features of construction and operation, as Will be more fully described and particularly pointed out in the specification, drawings and claims appended hereto. Y

The: end. uprights-z are joined. by'- the As best shown in Figure 2 the tunnels: 101i 4 partitions or bulkheads I2. The longitudinal beams 29, Figures 1 and 2, therefore extend from bulkhead to bulkhead, whereas the

transverse beams

28 and 30 extend from one side Wall 3| of the hold I to the opposite side Wall 32. The side Walls 3| and 32 are reinforced and strengthened'; .at1Q intervals by thew vertically extending beams 33:: The transversebeams 28|.and 3G are suitably secured at their respective ends to the vertical beams 3S. The longitudinally extending beams.2.9.are.also supported in any suitable mannerrat their respective ends from the bulkheads and` it will be observed from Figure 2 that notched; horizontallygextending brackets 34 are providedxtozftake-:rthe place of the beams adjacent the side Walls ofthe-vessel.

In Figures 3.and.4 of the hold of a conventional ship having a flat tank bottom is shown equipped withsthe-topen beam construction for storing the containers.

Figu1e-5.i11us.trates the. manner in which the side. edges of. the.. beams arev notched. at regular intervals. The notches IlI and 4'Ifreceive the .legs

of.. thecontainer andare spaceda distance equal to. the.over all.width off the container. In other Words,.the.dis.tance between notches i'and,v 47| is actually, the. distance. between. the legs on the shorterv sideof. the container. The beams are spaced adistancemeasuredirom center to center slightly greater.. than. the, length between the-legs of .'thezcontainer.

In. accordance.. With the invention the containers are rectangular in plan and therefore the ,distancebetween notches-46 and .4.1 is less than the spacebetween the. side. edge ofv one beamand the. side edge-of. thenext adjacent. beam. This manner. of` spacing` the beamsrenders itpossible to` lower thecontainers.` past certain beams for support onzbeams forming, the lower level. The containers are suiiiciently narrow. toV pass through theA space between. beams and the beams on the level beloware properly arranged for receiving and supportingthem, provided the transverse and longitudinal positioningv of thek beams for the diflerentlevelsis employed.

Thefnotches.v 46- and 57|. are formed in the horizontal flange oi' the T-shaped beam. Each notch. receivesy a. legv of. the container and the portion-daftherefore provides the support for the 42 in Figure 5, auxiliary brackets 50 are provided to supplementth'e beams. In said gure the brackets extendalong and are suitably secured to the

side walls

36 and 31. For the transverse beams 40 similar brackets 5| extend along and are secured to the bulkheads.

For maximum utilization of the space within the hold of the ship it is necessary to locate the containers as close to each other as possible. As shown in the drawings very little space is left unoccupied. By providing one or more .large hatch'es over the hold the containers are easily located within or removed from the holds. This speeds up the loading and unloading and reduces the time required for the ship to remain in dock. Th'e container ship and the package freight containers to be presently described in detail also eliminate intermediate handling of the individual packages and further eliminate hand handling of the cargo on the ship.

The collapsible container of the invention is shown in side and end elevational views in Figures 6 and 7. Numeral 55 indicates the iloor plate of the container, which is supported in elevated position by four legs, numeral 56 indicating the two legs adjacent the left end of the container, Figure 6, and numeral 51 indicating the two legs adjacent th'e right end. The legs comprise corner elements of the container and have a right angled shape in cross section. End iioor channels 58 are located at each end of the floor plate, being suitably secured thereto and which in turn form securing means for the legs of the container. The sides of the floor plate 55 are provided with base plates 59 and 60 which are of greater height than the end channels 58 and thus extend above the iioor. Said base plates likewise have the legs of the container secured thereto, whereby the bottom portion of the container constitutes an integral unit with' the iioor plate, channels, base plates-and legs all being secured to one another. The base plates 59 and 60 are reinforced at intervals bythe vertical stiifeners 6| and plate brackets 62 extend from each side plate to the floor plate at the respective ends of the same.

From an inspection of Figures '7 and 10 it will be observed that the base plate 60 extends above the floor plate to a height somewhat in excess of that of base plate 59. This construction is resorted to in order to make possible the collapsing of the container, as best shown in Figure 10. The side uprights 63 and 64 are each fabricated from structural parts, as shown by Figure 6, and each upright is pivotally secured along its bottom edge to one of the base platesA comprising an integral part of the container. A full hinge 65 and two half hinges 66 and 61 may be employed. Each upright essentially consists of a top brace channel 68, a bottom brace channel 69, and end

channel members

10 and 1 The parts are suitably secured to form a substantially rectangular frame which is reinforced and strengthened by the diagonally extending braced channels 12 and the horizontally extending channels 13. Platebrackets 14 may be located at one or more corners and the channels 12 may be additionally secured to the top and bottom channels by means of plate brackets such as 15. For lifting the containers two or more lift rings 16 are suitably seflied in spaced relation to the top brace channe Since each side upright is pivotally secured forming the bottom portion of the container, it

6 is necessary to provide releasable means for holding the uprights in vertical position. This structure essentially consists of top pipe battens, indicated by numeral 18, Figures 7 and 8. Batten sockets 19 are suitably secured to the inside surface ofthe top brace channels 68 of each' upright and the top pipe battens are provided at their respective ends with a cap portion 80, see Figure 11. The inside wall of each socket is provided with a centrally positioned pin 8| and the face of each cap portion 80 is formed with a recess or opening 82 somewhat elongated in extent and leading from the circumference of the cap portion to slightly beyond its center. It will therefore be understood that when the top pipe battens are inserted in place with the cap portions 89 entering the sockets, the pins 8| will be received by the recesses or openings 82. The top pipe battens will remain in pl-ace unless positively lifted from their sockets but it is relatively simple to lock the battens in place merely by turning them 180 degrees, since the pins 8| will then prevent lifting of th'e battens from their sockets. The locking action, however, is releasable since the battens need only be turned to properly align the recesses or openings 82 whereby they can be lifted.

The spring tension. rods 84 extend diagonally at each end of the container. Said rods serve to prevent a'racking distortion to the container when the container isliited.` For collapsing purposes an-d to also facilitate unloading the spring tension rods are removable. Each rod at one end has connection with a pin 85 extending inwardly fromI the outer wall of the

end channel members

10 and 1|. At the opposite end of the tension rods a bayonet type of opening 86, Figure 9, is provided in the enlarged head 81. Said head, by means of the opening, is releasably secured to pin 88 extending inwardly from the plate brackets 62. Each rod has limited spring tension fby means of the structure shown in Figure 9. The enlarged head 81 is formed on part 89 of the tension rod, which is separable from the main part 84. By means of the coil spring 90 and its associated stnucture limited separation is possible, with the result that the tension rod can be releasably secured to parts of the container to apply the desired tension to the uprights. The coil spring 90 is conned between the washer 9| suitably welded to part 89 and the cylinder 92 secured to the main portion 84 of thetension rod by means `of the threaded engagement which the cylinder has with the boss 93; Said boss is suitably secured to the terminal end of said main portion 84 of the rod and it will therefore be seen that any tension applied to the rod will permit elongation by compression of coil spring 90.

It will be 4clear from Figure 7 that the diagonal crossing of the tension rods 84 does not close the end of the container to an extent preventing inadvertent removal or loss of the individual packages stored within the container. However, it is desirable, since the containers embody the collapsing feature, to provide closure means which will be relatively simple in nature and easily removed or installed. For this purpose end pipe battens 94 are employed. For receiving said end pipe battens the

end channels

10 and 1| are closed by plates 95. As best shown in Figure 12, the plates 95 are provided with a plurality of openings 96 and each end lbatten is slotted as at 91. The battens are thus located in their n proper opening and dropped into place, with the result that they are releasably heldin connected sans@ ..i@historians-shaw means. of the.
