发明名称 Test weight scale
摘要 A portable, hand-held test weight scale for testing the bushel weight of grains. A slide beam having weight increments marked along its length is joined at one end to a grain cannister of predetermined volume. Means are provided for pivotally suspending the scale at a point of pivotal attachment to the beam, and a weight slidably supported on the beam is slidably adjusted thereon until the scale is balanced. A balanced condition is indicated by the level orientation of the beam as it is pivotally suspended.
