ABSTRACT:
A weight indicator comprises an open top casing containing a resilient column, a relatively rigid pad extending across the top of the column and a scale mechanism for indicating vertical compression of the column in response to weight applied downwardly on the pad, a frictionally mounted indicator element on the casing being movable along a graduated scale on the casing and there being a projection on the pad for displacing the indicator element along the scale as the column reduces in height in response to said downwardly applied weight.
