2013.3.86Description
Description from L.A. Brown's 1959 catalog: "A pump notable not only for its size and weight but for the fact that it was the first "continuous movement" pump. It was made by the famous instrument maker, Charles Chevalier. Extensive notes came with this pump. They are concerned with its operation, cleaning, etc. Chevalier made several styles of continuous motion pumps. One was made with a single fly wheel instead of the two as in the pump illustrated. A sliding rod receiver is shown in the platform of this pump.
The pump, and the apparatus which were purchased for use with it, were listed by Dr. Fall as costing $1070.00."Collection
