Air pump

This double-action, double-barrelled air pump was made around 1870, probably by Eugene Ducretet (1844-1915), a scientific instrument maker based in Paris.

The pump has its pistons visible in twin glass cylinders, a feature more common in European air pumps than those made in Britain. It is signed above the barrels 'E. Ducretet & Cie / Paris'. There is a separate mercury manometer, which acts like a small barometer tube, and measures the pressure of the air in the collecting vessel (in this case a bulbous tube).

The firm of Ducretet was founded in 1864, and a trade catalogue issued by the firm dating from 1879 offers three sizes of this model of air pump, depending on the size of the plate carrying the bell jar (not shown), from 350 francs to 750 francs.
