Antique scales come in many different types such as spring, balance and platform scales used in railroad and grain elevator operations. Early spring scales were created by carefully winding and heat treating coiled wire with consistent properties so each time pressure was applied a certain compression or travel was achieved. Balance and platform scales used a completely different design concept where arms and small weights created a mechanical advantage which translated weight onto a horizontal or linear weight scale.
