摘要： A guage such as is used in connection with a Bourdon tube comprises two bearing plates, at least two metallic spacer columns interconnecting the bearing plates, a pointer shaft rotatably mounted between the bearing plates, and a spiral spring fixed at its inner end to the shaft. One spacer column has an axial slot extending from one end of the column for receiving the outer end of the spiral spring. The outer spring end is inserted into the slot when the pointer shaft carrying the spring is assembled thereby saving the extra step in the manufacturing process required for locating the outer spring end in conventional gauges of this type. The slotted end of the spacer column extends beyond the outer side of the respective bearing plate so that the slot may be engaged by a screw driver for pre-tensioning the spring after complete assembly of the gauge.
