Claim 6

A mobile vehicle according to claim 4 wherein said unloading means comprises two hoppers.

Claim 7

A mobile vehicle according to claim 1 wherein said framework means comprises a plurality of tubular members interconnected to form a truss frame to support and carry said container means and said bulk material therein, so as to substantially eliminate side wall loading by said bulk materials.

Claim 8

Claim 9

A mobile over the road-type vehicle for carrying, selectively, liquid and dry bulk materials and general freight comprising in combination: mobile trailer means including platform means, a plurality of openings formed in said platform means, framework means mounted upon said platform means above said openings, a plurality of container means each comprising a generally cylindrical, bag-like member of strong, lightweight material such as Kevlar, and having a support ring about its upper periphery and an open bottom end portion engaged substantially about the periphery of one of said plurality of openings and each container means being selectively erectable, cable means for removably attaching each said support ring to said framework means to support the container when erected, for containing, selectively, said liquid and dry bulk materials, a plurality of unloading means mounted below said plurality of opening means to define bottoms thereof and of said plurality of container means, ones of said unloading means being adapted for unloading said dry bulk materials and others of said unloading means being adapted for unloading said liquid bulk materials, said container means further being selectively collapsible for being carried in said unloading means and cover means selectively attachable over said openings to form a continuation of said platform means for adapting said vehicle for carrying general freight loads.

Claim 10

A mobile over the road-type vehicle for carrying, selectively, liquid and dry bulk materials and general freight comprising in combination: mobile trailer means including platform means, a plurality of openings formed in said platform means, framework means mounted upon said platform means above said openings, a plurality of container means each comprising a generally cylindrical, bag-like member of strong, lightweight material such as Kevlar, and having a support ring about its upper periphery and an open bottom end portion engaged substantially about the periphery of one of said plurality of openings and each container means being selectively erectable, cable means for removably attaching each said support ring to said framework means to support the container when erected, for containing, selectively, said liquid and dry bulk materials, a plurality of unloading means mounted below said plurality of opening means to define bottoms thereof and of said plurality of container means, ones of said unloading means being adapted for unloading said dry bulk materials and others of said unloading means being adapted for unloading said liquid bulk materials, said container means further being selectively collapsible for being carried in said unloading means and cover means selectively attachable over said openings to form a continuation of said platform means for adapting said vehicle for carrying general freight loads.

Claim 11

A mobile vehicle according to claim 8 wherein said opening means comprises four openings formed along the length of said platform means and said container means comprises four containers attached substantially about the respective peripheries of said openings.

Claim 12

A mobile vehicle according to claim 8 wherein said unloading means comprises two substantially conical hoppers for unloading of dry bulk materials, mounted below two of said four containers and two generally conical slope pans for unloading of liquid bulk materials mounted below another two of said four containers.

Claim 13

A mobile vehicle according to claim 8 further including air pressure means for inflating said collapsible container means to erect said container means for carrying said bulk materials and for providing pressurized unloading means for said bulk materials.

Claim 14

A mobile vehicle according to claim 8 further including means for removably engaging said bottom end portions of the container means about said peripheries of said openings for selectively removing and replacing said container means.
