First Claim
Patent Images
1. A weighing structure comprised of:
- a. A support base capable of supporting a plurality of variable moment load cells where the structural member of the load cell is supported by a load cell support in an essentially horizontal position, and where,b. the variable moment load cell structural member supports a movable carriage that can be positioned and secured in an infinite number of positions along the longitudinal axis of the load cell within its adjustment range and where,c. the movable carriage on the structural member of the load cell is further attached to a vertical supporting member that supports the weighing platform and where,d. a means is provided to adjust the distance between the variable moment load cell support on the base and the weighing platform over an infinite number of positions within the longitudinal adjustment range of the variable moment load cells.

Abstract
Multiple methods of constructing weighing platforms using variable moment load cells are disclosed. Variable moment load cells require only a single strain gage and typically four (4) are used on a weighing platform. The output of the four (4) load cells are matched by mechanically varying the bending strain detected by the strain gages.
A method of constructing a load cell to weigh suspended hoppers with a minimum of vertical space is also disclosed.
