ABSTRACT:
A device for establishing dial settings for a plurality of control shafts in a close group for use with electrical apparatus, involves a secondary stop assembly, which may be in the form of a single preset plate or template or in the form of a sophisticated assembly containing multiple plates and rotatable secondary stops. Further, a shaft driving device is disclosed which involves the use of a slip clutch, which will turn each of the shafts until a positive resistance is reached, and then the clutch will slip so as to establish a dial setting for each shaft at a desired point. The device is used in conjunction with control shaft groups in which each of the control shafts is equipped with a shaft stop in the form of a collar fitted onto the shaft and having a radially projecting lug acting as the shaft stop.
