Instruction Manual for Gerber GraphAnalogue

The citation information for this 52-page stapled booklet is: H. J. Gerber, The Gerber GraphAnalogue (Hartford, Conn.: The Gerber Scientific Instrument Company, 1953). The booklet explains the construction and use of the Gerber GraphAnalogue. (See 1994.0113.02.)
It then describes typical problems that could be solved with the instrument: plotting a family of curves; reading printed graphs without having to replot them; reproducing drawings at unusual scales; normalizing curves; interpolating points; counting frequency cycles; enlarging or reducing diagrams; determining pressure ratios; solving navigation and center of gravity problems; reading oscillograms and aerial photographs; spacing rivets; setting up engineering scales; determining a rate of elevation; estimating functions; and multiplying and dividing. The company sold specially-sized graph paper that could be laid on the base in order to plot curves.
