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.
