Description: | Lead and Leather Pump Seal Weight. Cast circular plate with one straight edge, and with a grooved boss on the underside. This retains traces of a leather diaphragm. In operation - whether powered manually or by an engine - the weight of the lead plate would ensure the leather seal remained airtight to maintain suction. Pumps were used extensively in engineering projects from the 17th century onwards. The mass of the object may suggest this was a ten ounce weight. Suggested date: Post-Medieval, 1650-1950.Diameter: 61.7mm, Thickness (overall): 21.2mm, Weight: c.280gms.
