Abstract
Abstract This invention relates to wheeled load conveyances of the type having a load container to be elevated when the conveyance is not moving and is to be stabilized against movement. The embodiment shown in the drawing is incorporated in a portable water carrier which includes a vehicle frame mounted on wheels and a water tank mounted on the frame by a supporting structure which can be moved to elevate the load above the frame. A stabilizing structure is included to which the weight of the vehicle and the load can be transferred to remove that weight from the wheels. Force is applied to the movable supporting structure to raise the tank and this movement is utilized to transfer weight from the wheels to the stabilizing structure, which in this case is the frame itself. Force is applied by a block and tackle arrangement to raise the tank from the frame. A second block and tackle arrangement utilizes that movement, the relative movement between the frame and the tank, to accomplish relative movement between the wheels and the frame whereby to transfer the load between the wheels and frame.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
126 words
In combination: a load container; a stabilizing frame disposed generally horizontally below the container; means for raising and lowering said load container and for raising and lowering said frame including a pair of moveable support structures connected at one end to spaced points on opposite ends of the load container and at the opposite end to horizontally spaced points on opposite ends of said frame; wheels carried by the frame intermediate said horizontally spaced points of the frame; and wheel positioning means comprising a block and tackle system responsive to raising and lowering of the load container relative to the frame for respectively lowering and raising the frame relative to the wheels while maintaining the wheels in a position between said spaced points of the frame.
Claim 2
Dependent Claim
126 words
In combination: a load container; a stabilizing frame disposed generally horizontally below the container; means for raising and lowering said load container and for raising and lowering said frame including a pair of moveable support structures connected at one end to spaced points on opposite ends of the load container and at the opposite end to horizontally spaced points on opposite ends of said frame; wheels carried by the frame intermediate said horizontally spaced points of the frame; and wheel positioning means comprising a block and tackle system responsive to raising and lowering of the load container relative to the frame for respectively lowering and raising the frame relative to the wheels while maintaining the wheels in a position between said spaced points of the frame.
Claim 3
Dependent Claim
230 words
In a load conveyance of the type having a load container to be elevated while the conveyance is stationary: transporting wheels upon which the conveyance is mounted; stabilizing means carried by said conveyance and comprising an element moveable relative to said wheels to the level of the bottom of said wheels for transferring a portion of weight of the load from the wheels to said element; elevating means comprising a moveable support structure interconnecting said wheels and said load container for elevating the latter relative to said element and for lowering said element relative to said wheels; said elevating means being effective to lower said element relative to said wheels during initial elevational movement of said load container; said conveyance comprising a frame, said wheels being mounted on said frame and moveable relative thereto in a vertical direction, said support structure interconnecting said frame and said load container, and said elevating means further comprising means for translating movement relative to said frame of said support structure and said load container into relative motion between said wheels and said frame; and in which said means for translating movement of the support structure and the load container relative to the frame comprises a block and tackle system the tackle of which is extended and contracted as an incident to movement of said support structure and said load container relative to said frame.
Claim 4
Dependent Claim
230 words
In a load conveyance of the type having a load container to be elevated while the conveyance is stationary: transporting wheels upon which the conveyance is mounted; stabilizing means carried by said conveyance and comprising an element moveable relative to said wheels to the level of the bottom of said wheels for transferring a portion of weight of the load from the wheels to said element; elevating means comprising a moveable support structure interconnecting said wheels and said load container for elevating the latter relative to said element and for lowering said element relative to said wheels; said elevating means being effective to lower said element relative to said wheels during initial elevational movement of said load container; said conveyance comprising a frame, said wheels being mounted on said frame and moveable relative thereto in a vertical direction, said support structure interconnecting said frame and said load container, and said elevating means further comprising means for translating movement relative to said frame of said support structure and said load container into relative motion between said wheels and said frame; and in which said means for translating movement of the support structure and the load container relative to the frame comprises a block and tackle system the tackle of which is extended and contracted as an incident to movement of said support structure and said load container relative to said frame.
Claim 5
Dependent Claim
59 words
The invention defined in claim 2, in which said elevating means further comprises a block and tackle element connected to said frame and said support structure and effective as an incident to application of external force to the tackle thereof to cause movement of said support structure in direction to alter the degree of elevation of said load container.
Claim 6
Dependent Claim
30 words
The invention defined in claim 3, in which said support structure comprises arms pivoted at one end on said frame and pivoted at the other end on said load container.
Claim 7
Dependent Claim
37 words
The invention defined in claim 4, in which said wheels include a resilient element which is subjected to the weight of the conveyance aNd is interposed between the frame and the surface on which said wheels rest.
Claim 8
Dependent Claim
