Abstract
Abstract The present disclosure is directed to arranging a weigh hopper in a free floating manner in a rigid frame so that the hopper either rests upon a load cell or pulls on a load cell while the hopper is free to move up and down in a rigid frame only influenced by flexing aligning rods which are not rigidly secured to the weigh hopper but are secured to the rigid frame. This structure eliminates the usual multiplicity of load cells common to this art.

Claim 1
Independent Claim
153 words
A weigh hopper stabilizing and weighing system comprising: a. a weigh hopper, b. a rigid frame about said weigh hopper, c. a single load cell, d. load cell support means connected to said rigid frame positioning said single load cell so that said weigh hopper bears directly thereon, e. weigh hopper aligning rods one end of each of which is secured to said rigid frame and the other end of which engages the hopper but it is not secured thereto but are spaced about the weigh hopper for centering the weigh hopper over and upon the load cell, and f. a bulk material bin having discharge outlet means, rigid spacer means connected to space said rigid frame and weigh hopper below said bin discharge outlet means, said load cell support means being a spider frame having a central rod with the single load cell connected between said spider frame and the bulk bin.
