Abstract
10,959. Hertzberg, H., Snyder, W. P., Griffin, J. H., and Bernhard, H. I. May 25. Scales; index hands.-In apparatus in which the indications of two independent electrical instruments are compounded to give a reading in different units by the crossing of their pointers, these are arranged to intersect in every position. The chart shown is graduated in terms of amperes, volts, watts, and horse-power. In a modification, the order of numbering is reversed. In another modification, the pointers are replaced by overlapping sectors, an index being marked on the upper and a series of intersecting circles on the lower sector, graduated in watts or other units, the curved edges being graduated in volts and amperes, respectively.
