1901 J. H. Bullard U.S. Patent 685,569 This invention relates to gradometers, and has for its object the construction of an instrument of this class adapted especially to use on self-propelled vehicles... The usual curved glass tube..is provided with graduation-marks, indicating the per cent. of inclination of the device relative to the horizen [sic].

1904 G. F. Goodchild & C. F. Tweney Technol. & Sci. Dict. 266/1 Gradometer, an instrument for measuring the angle of dip of a rock formation or mineral deposit.

1924 F. Caldwell U.S. Patent 1,492,156 Improvement in Gradometers..relates to the visible indication of the grade up or down on which a vehicle..is travelling or standing, on which an aircraft is travelling, or the extent to which a ship is rolling or pitching.
