AMSLER'S 3-WHEEL MECHANICAL INTEGRATOR sold by KEUFFEL & ESSER
19-007. Swiss, mid 20th century, signed on the frame "AMSLER" and with a metal trade lable for "KEUFFEL & ESSER Co." It is described in the 1955 Keuffel & Esser catalog as follows: "Amsler's Integrator, with three recording mechanisms giving the area, moment, and moment of inertia of any figure; two tracing points, two gauges for adjusting intrument to axis of moments; instrument in wood case." Made of gray enameled steel, this unusual mechanical integrator is in very good overall condition, in its original fitted wood case; however, the grooved 67" steel rail in a separate wood case is not included.
