Apparatus for overload protection of precision or analysis scales having a parallel-guided load support with limit stops to limit the range of movement thereof, comprises an auxiliary parallel guide connection between the weighing pan and load support, and resiliently yieldable means connected between the weighing pan and load support to yield under excessive or improperly placed loads and thus protect the scale mechanism. The resiliently yieldable means may comprise the auxiliary parallel guide or may comprise a separate means.

Apparatus for overload protection of precision scales

An overload protection device for a top pan precision scale having a weighing pan support and a support plate carried by a load support mounted for limited movement and connected to an indicator, includes a spring engaged between the weighing pan support and the support plate whereby the weighing pan support is resiliently coupled to the load support, and a plurality of overlapping elements carried by the weighing pan support and extending beyond the outer peripheral edge of the support plate in close proximity thereto so that the weighing pan support and support plate are held in assembled relationship against the bias of the spring by the overlapping elements at the outer peripheral edge of the support plate, whereby upon eccentric loading of the scale, the pivot point of the weighing pan support is extended to the side of the weighing pan support opposite the load, and the lever translation thus effected results in a lower load on the load support than the highest available load.
