Troemner Gem Scale, No. 5

Troemner Gem Scale, No. 5

This is a Roberval balance with one round pan, one elongated pan, a rectangular iron base, and space for five weights (one is missing). A painted inscription reads “HENRY TROEMNER / MAKER / PHILADELPHIA.” “GEM NO 5” is in raised letters. This model was said to be “small, light and ornamental,” and adapted for weighing such things as lozenges and bon-bons.
