Abstract
Abstract A portable cargo container in combination with a generally Ushaped horizontal body frame of a trailer having two spaced parallel longitudinal frame members; the upper section of the container is wider than the space between said longitudinal frame members, and the lower container section is narrower than the space between said longitudinal frame members and is higher than the distance of said longitudinal frame members from the ground level so as to permit the longitudinal frame members to be backed under said upper section for loading; said lower section being adapted to serve as a base to support the container on the ground thereby to eliminate the need for multiplicity of trailers.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
180 words
A portable cargo container for use with a trailer, having a body frame with two parallel spaced longitudinal sections open at its rear end and container lifting means on said longitudinal sections, said container being characterized by: an upper section having a width at least equal to that of said body frame thereby to overlap said longitudinal sections, a lower section capable of containing cargo and having a width substantially less than that of said upper section and less than the spacing between said longitudinal sections thereby forming longitudinal shoulders engageable with said longitudinal sections and said lifting means, said trailer being disposed to straddle said lower section of said container between said longitudinal sections while permitting said upper section to rest upon said longitudinal sections, said upper section and said lower section of said container being separated by a floor comprising a plurality of trap doors, said lower section having a vertical rear end wall, a lower horizontal edge on said end wall, said edge including a ramp for access to said container when said end wall is opened.
Claim 2
Dependent Claim
180 words
A portable cargo container for use with a trailer, having a body frame with two parallel spaced longitudinal sections open at its rear end and container lifting means on said longitudinal sections, said container being characterized by: an upper section having a width at least equal to that of said body frame thereby to overlap said longitudinal sections, a lower section capable of containing cargo and having a width substantially less than that of said upper section and less than the spacing between said longitudinal sections thereby forming longitudinal shoulders engageable with said longitudinal sections and said lifting means, said trailer being disposed to straddle said lower section of said container between said longitudinal sections while permitting said upper section to rest upon said longitudinal sections, said upper section and said lower section of said container being separated by a floor comprising a plurality of trap doors, said lower section having a vertical rear end wall, a lower horizontal edge on said end wall, said edge including a ramp for access to said container when said end wall is opened.
Claim 3
Dependent Claim
49 words
The combination of claim 1, and the height of said lower section being greater than the distance of said longitudinal frame sections from the ground level to permit the backing of said longitudinal sections and said lifting means under said shoulders when said lower section rests on the ground.
Claim 4
Dependent Claim
23 words
The combination of claim 2, and longitudinal ledges formed on said lower section spaced from the bottom thereof to form additional lifting support.
Claim 5
Dependent Claim
13 words
The combination of claim 2, wherein said container consists of a support frame.
