摘要：A platform balance including a housing, a weighing platform vertically movablerelative to said housing, and at least one force indicating lever pivotally movable inaccordance with the mass to be weighed by said balance, characterized in that the forceindicating lever is pivotally supported in said housing beneath said platform at the upperend of a vertical support member the lower end of which is pivotally connected with thebottom wall of the housing, said force indicating lever being operable by the platform viaload lever linkage means connected between the opposed side walls of the housing. Inthe illustrated embodiment, a pair of symmetrical force indicating levers are connectedfor pivotal movement in opposite directions to increase the sensitivity of measurement.Adjustable weight means are provided for varying the operating range of the balance,and tangent error is compensated for by appropriate selection of the dimensions andlocation of the center of gravity of the vertical support member.
