Abstract
Abstract A structure for transporting and storing flowable materials. The structure includes a silo compartment, which has a central axis, this compartment being adapted to receive and discharge flowable materials when its axis is upright and being adapted to transport the materials when its axis is in a substantially horizontal attitude. The silo compartment is made of a foldable sheet material so that it can be readily placed in a collapsed condition when it is not used. A supporting framework extends around and is operatively connected with the silo compartment to support the latter both with its axis upright and with its axis in the substantially horizontal attitude.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
135 words
In a structure for transporting and storing flowable materials, silo compartment means, having a central axis, for receiving and discharging flowable materials when said axis is upright, said silo compartment means being composed of a flexible sheet material which can be folded when the silo compartment means is empty for collapsing the latter to a condition of nonuse, and Support means extending around and operatively connected with said silo compartment means for supporting the latter with said central axis thereof upright, said support means including an outer framework extending around said compartment means and a multipartite ring removably carried by said framework and from which said compartment means is suspended when the axis thereof is upright, said compartment means having extensions extending up to and connected with said ring for suspending said compartment means therefrom.
Claim 2
Dependent Claim
135 words
In a structure for transporting and storing flowable materials, silo compartment means, having a central axis, for receiving and discharging flowable materials when said axis is upright, said silo compartment means being composed of a flexible sheet material which can be folded when the silo compartment means is empty for collapsing the latter to a condition of nonuse, and Support means extending around and operatively connected with said silo compartment means for supporting the latter with said central axis thereof upright, said support means including an outer framework extending around said compartment means and a multipartite ring removably carried by said framework and from which said compartment means is suspended when the axis thereof is upright, said compartment means having extensions extending up to and connected with said ring for suspending said compartment means therefrom.
Claim 3
Dependent Claim
37 words
The combination of claim 1 and wherein said support means has, when said silo compartment means is folded in its collapsed condition, a substantial interior space for receiving articles which may be transported within said support means.
Claim 4
Dependent Claim
32 words
The combination of claim 1 and wherein said support means is in the form of a framework which is collapsible to occupy a substantially small volume when in a condition of nonuse.
Claim 5
Dependent Claim
24 words
The combination of claim 1 and wherein said silo compartment means is of a cylindrical configuration and has opposed ends of tapered, frustoconical configuration.
Claim 6
Dependent Claim
69 words
The combination of claim 1 and wherein said compartment means and support means are transportable with said axis in a horizontal position and wherein lugs are fixed to said compartment means and engage said support means and loops are fixed to said compartment means and operatively connected with said support means so that kinetic and static forces will be transmitted to said support means through said lugs and loops.
