Design and Construction of Model SC401

The REGAL Model SC401 dual cylinder scale is an improved design
consisting of a rein- forced 1-1 /2- high PVC base with two weighing
platforms, each operating independently. The base also supports an
adjustable steel crossbar with chains which secure the gas cylinders in
an upright position. At the top of the column is the scale head
containing two independent read-out dials and tare adjustment
mechanisms. The two 12- diameter weighing platforms are independently
supported by a system of mechanisms which transmits each load to its
respective weighing system and read-out dial on the scale head. Tare
weight is compensated for with two adjustment knobs connected to the
weighing system with spring mechanisms, allowing direct read-out of
contents of each weighing platform.
