BEAMSCALES & BALANCES

Apothecary's Beam Scale

Beamscales & Balances
These types of scales are often refered to as equal-arm
or beam scales and are some of the earliest scales in existance. This simple scale uses a 'beam' or 'arm' balanced so that equal lengths protrude horizontally off the centre,
with the weighing pans hanging off the ends of the beam, on cords, chains or rods. The unknown quantity to be weighed
is placed in one of the pans and in the other pan are placed weights of a known quantity. When the beam becomes exactly horizontal the correct weight has been calculated
.

Large Iron Beam Scale

Above: Antique Apothecary's Beamscale dating from the 1870s.
No makers mark. This brass beamscale is fully complete and in excellent condition;
with original beam, knife-edges, shackles, end-bearings and supporting metal and removable glass pan. When released, the brass lever allows the pans to rest which
reduces the pressure on the knife-edges. The weights are drachm, scruple and grain
weights.
For portability the brass scale is removeable from the base and each part is
collapsible; for easy storage the parts are placed in the drawer of the mahogany box.
The base is 10.5 inches (27cm) by 5 inches (13cm) with a depth of 2 inches (2cm) -
the scale has a total height of 12 inches (31cm).

This equal-arm beam scale made of brass and iron has a cranked hanger (the hanger
is the rigid rod hanging from the end of the arm - they can be straight, curved, cranked,
bow or a stirrup hanger). Many later scales of this type have a flat porcelain plate used
to weigh meats or cheese etc in a butchers or grocers shop.
