In the transportation industry, it has been the customary practice to utilize separate types of carrier units for transporting general cargo and bulk materials. More recently, efforts have been made to devise multipurpose carrier units which are adapted to carry either general cargo or bulk material. It has been found, however, that such convertible carrier units in the prior art have not been entirely satisfactory from the viewpoint of simplicity, cost of manufacture and operating performance.
Accordingly, it is the principal object of the present invention to provide the novel carrier unit.
Another object of the present invention is to provide a novel carrier unit which is adapted to carry either general cargo or bulk materials.
A further object of the present invention is to provide a novel carrier unit normally adapted to carry general cargo which is convertible into a bulk material carrier.
A still further object of the present invention is to provide a novel convertible carrier unit adapted to carry either general cargo or bulk materials, which is adapted to facilitate the loading and unloading of bulk materials.
Another object of the present invention is to provide a novel convertible carrier unit adapted to carry either general cargo or bulk material which is adapted to be loaded and unloaded with bulk material by gravity feed.
A further object of the present invention is to provide a novel convertible carrier unit for transporting either general cargo or bulk material which can be constructed by simple modification of conventional carrier units.
A still further object of the present invention is to provide a novel convertible carrier unit adapted to carry exclusively general cargo or a combination of bulk materials and general cargo.
Another object of the present invention is to provide a novel convertible carrier unit adapted to carry gen- -eral cargo, bulk material or a combination of general FIG. 3 is an enlarged cross-sectional view taken along line 3,3 in FIG. 2;
FIG. 4 is a view similar to the view shown in FIG. 3, illustrating a component thereof in an alternate position;
FIG. 5 is a partial, longitudinal sectional view of the embodiment illustrated in FIGS. 1 through 4, illustrating the embodiment in a condition for receiving general cargo; and

A pair of latch bolts 80 and 81 are provided in the lower frame member 71 which are receivable in holes adjacent the rear end of the opening 37 to secure the wall unit 13 in its operative position as best illustrated in FIG. 2.
The front face of the panel 67 is provided with a hinged panel 82 which is similar in construction to the hinged panel 58 connected to the wall unit 12. As best shown in FIG. 2, when the wall unit 13 and the panel 82 are disposed in their operative positions the free transverse edge of the panel 82 will engage the floor 22 adjacent the rear edge of the opening 37, and the converging side edges thereof will engage the inclined surfaces of the floor sections 34 and 35, with the parallel side edges thereof disposed adjacent the side walls 23 and 24 of the container. The panel 82 is movable be tween an operative position as illustrated in FIG. 2 and an inoperative or storage position as illustrated in FIG.
When the floor sections 31 through 36 are in their open, operative positions, the wall units 12 and 13 are in their operative positions adjacent the front and rear edges of opening 37, and the panels 58 and 82 are swung downwardly as illustrated in FIGS. 1 and 2, such components, in cooperation with portions of side walls 23 and 24, and top wall 25 of the container, define a compartment 83 having a rectangularly shaped upper section and a funnel-shaped lower section communicating through the opening 37 with the interior of the hoppers 38. The flexible liner 14 in its expanded condition is provided with a configuration which substantially conforms to the configuration to the compartment 83. More specifically, the liner 14 includes a top panel 84 adapted to lie adjacent the top wall 25, a side panel 85 adapted to lie adjacent the side wall 23 and rest at its lower end on the inclined surfaces provided by the floor sections 32, 34 and 36, a side panel 86 adapted to lie adjacent side wall 24 and rest at its lower end on the inclined surfaces provided by the floor sections 31, 33 and 35, a front end panel 87 adapted to lie adjacent to panel 41 of wall unit 12 and rest at its lower end on the inclined surface provided by the panel 58,
and a rear end panel 88 adapted to lie adjacent the panel 67 of wall unit 13 and rest at its lower end on the panel 82. The lower end of the flexible liner may simply be open to communicate with the interior of the hoppers 38 through the opening 37 or may be provided with projecting portions extending through the opening 37 into the hoppers 38.
The flexible liner 14 is supported within the compartment by means of a plurality of transversely disposed hanger rods 89 which extend through tunnel loops 90 provided on top panel 84 of the liner, each of which are provided with rollers 91 and 92 at the ends thereof which ride on a pair of transversely spaced guide tracks 93 and 94 disposed adjacent the guide tracks 54 and 55. The front and rear liner panels 87 and 88 are provided with tunnel loops 93 and 94 at the upper ends thereof which are adapted to receive therethrough hanger rods 95 and 96 which are rigidly mounted on the upper ends of the panels 41 and 67 of wall units 12 and I3. The side panels of the liner further are supported by a plurality of straps 97 provided at the upper ends thereof which receive the ends of the hanger rods 89 therethrough. The lower portions of the side and end panels of the liner are maintained adjacent the side walls of the container and the wall units by means of a plurality of straps 98 which may be secured to suitable hooks provided in the side walls of the container and the panels 41 and 67 of the wall units. The upper panel 84 of the liner also is provided with a plurality of longitudinally spaced flexible conduit sections 99 which are registerable with and adapted to extend into the annu lar loading conduits 29 of the top wall of the container when the liner is in its expanded condition, as illustrated in FIG. 2. Each of the conduits is provided with an opening in the upper end thereof which may be closed with an interlocking fastener or zipper 100.
When it is desired to utilize the carrier unit as described to transport general cargo, the floor sections 31 through 36 are swung downwardly into the positions as illustrated in FIG. 6, flush with the container floor 22, to close the opening 37, the panels 58 and 82 of the wall units are swung upwardly and secured against the panels 41 and 67, and the wall units 12 and 13 are rolled forwardly to the positions as illustrated in FIG. 5 and secured therein by means of the latch bolts 80 and 81 which are received in registerable holes in the container floor, so that the flexible liner 14 is supported from the hanger rods 89 and is disposed in folds between the wall units. With the various components of the carrier unit thus positioned, various types of cargo can be loaded into the container through the rear access doors.
Whenever it is desirable, however, to convert the carrier unit for transporting bulk material, the wall , units 12 and 13 are detached from their storage positions, moved forwardly to the positions as illustrated in FIGS. 1 through 4, and secured therein by means of the latch bolts 56, 57, 80 and 82. The positioning of the wall units as described will cause the flexible liner 14 to expand so that it will be suspended from the hanger rodds disposed adjacent the top wall of the container, and substantially will extend from one wall unit to the other with the conduit sections 99 being substantially registered with the annular conduits 29. A workman would then move the lower ends of the liner away from the side walls and rods units and swing the floor sections 31 through 36 outwardly into their operative positions as illustrated in FIGS. 1 through 4. After the floor sections have been positioned, the panels 58 and 82 are swung downwardly into position also as illustrated in FIGS. I through 6. With the compartment 83 thus formed, the side and end panels of the liner are secured to the side walls of the container and the wall units by means of the straps 98. Thus, the flexible liner will be in its expanded condition having a configuration conforming to the configuration of the compartment 83 with the lower open end thereof communicating with the interior of the hoppers 38 through the opening 37. The lower ends of the side and end panels of the liner will rest on the floor sections 31 through 36 and the panels 58 and 82, so that the lower end of the liner will be formed as a funnel for directing bulk material deposited therein through the opening 37 into the hoppers 38.
The panels 41 and 67 of the wall units are provided with doors 101 and 102 which provide access to the compartment 83 and also the container space between the wall unit 12 and the front end wall 26. It is contemplated that workmen assembling the unit for carrying bulk materials will utilize such access doors to move the floor sections 31 through 36 and the panels 58 and 82 into position and also to position the liner and secure it to the container walls and the wall units. The end walls of the liner also may be provided with closable openings to permit access to the interior of the liner so that any additional adjustments to the liner can be made. With the components thus assembled, the workmen may then exit through the rear opening of the container and close the rear access doors so that the unit will be ready to be loaded with the bulk material. This may be accomplished simply by opening the access doors 30, reaching down and pulling the sections 99 upwardly through the annular mountings 29, opening the sections 99 and inserting therein a chute or conduit for loading the bulk material into the liner. The bulk material can be loaded into the liner either by gravity feed or by a force feed method utilizing a pneumatic conveying system or the like. After the liner has been fully loaded, the liner is secured and the access doors are closed so that the carrier unit is then ready to be transported to its destination. It will be appreciated that when the liner is loaded, the bulk material will flow downwardly through the opening 37 into the hoppers 38 and eventually till the entire liner.
When the carrier unit has been moved to its destination and it is desired to unload it, this may be accomplished simply by connecting the discharge end 40 of the conduit 39 with a suitable conveying system, to draw the bulk material out of the unit. It will be appreciated that when a vacuum is applied to the conduit 39, bulk material within the liner will be caused to move downwardly through the hoppers 38 into the conduit 39, and be drawn outwardly through the discharge opening 40 into the conveying system. It further will be appreciated that the inclined surfaces provided by the floor sections 31 through 36 and panels 58 and 82 will facilitate the gravity flow of the material within the liner into the hoppers 38 and the conduit 39, so that all of the bulk material within the liner will be removed quickly and efficiently.
After the bulk material has thus been unloaded and it is desired to convert the carrier unit so that it again will be adapted to carry general cargo, the pneumatic conveying system is detached from the conduit 39, and
workmen enter the compartment 83 through the rear access doors of the container and access door 102 to detach the lower ends of the liner from the container walls and the wall units 12 and 13. As soon as this has been accomplished, the workmen next swing the panels 58 and 59 upwardly and secure them against the panels 41 and 67, and swing the floor sections 31 through 36 downwardly to close the opening 37. The latch bolts 56, 57, 80 and 81 are then lifted to their unlatched positions, the workmen exit through the access door 102 and then proceed to push the wall unit 13 forwardly so that the wall units with the liner disposed in folds between them are moved to the storage position as illustrated in FIG. 5. The latch bolts 80 and 81 are then dropped into position to secure the wall units in the storage position. At such time, the carrier unit will be in condition for loading general cargo in the conventional manner.
Although it is preferred that the flexible liner 14 be permanently installed within the container between the wall units 12 and 13, it would be possible to utilize a removable, flexible liner or to secure the flexible liner within the compartment in any other suitable manner. It further is contemplated that in lieu of providing a pair of wall units which are movable longitudinally within the container between storage and operable positions, such wall units may be hingedly connected to one or more walls and swung between storage and operative positions. By way of example, the wall units 12 and 13 could be hingedly connected to the top wall whereby the units can be swung upwardly and secured to the top wall for storage, and swung downwardly with the lower ends thereof secured to the floor, into their operative positions.
Referring to FIG. 2, it will be noted that when the carrier unit is assembled for carrying bulk material in the liner disposed within the compartment 83, there is provided a forwardly disposed compartment 103 between the front end wall 26 and the wall unit 12, and a rearwardly disposed compartment 104 between the wall unit 14 and the rear access doors. it is contemplated that by providing suitable access doors for the compartment 103, such compartments may be utilized for carrying general cargo while bulk material is carried in the liner within the compartment 83.
From the foregoing detailed description, it will be evident that there are a number of changes, adaptations, and modifications of the present invention which come within the province of those skilled in the art.
