Summary

This battery consists of a series of nine stamps arranged alternately in two rows, and all working in one mortar box which discharges from all sides. Each row of stamps is driven by a separate cam shaft. Patented by engineer Arthur Hope, Prahran, Victoria, 1865.

The working model depicts Hope's invention designed to 'improve' the process of extracting gold from quartz ore. The model was exhibited at the 1866-67 Intercolonial Exhibition of Australasia and the 1872-73 Victoria Exhibition before being donated to the Industrial and Technological Museum.

Physical Description

Working model of a stamp battery. Includes a wooden base, superstructure and stamps, which appear to have been painted, then coated in what may be a plant resin. The wooden base has a paper diagram of the nine stamps in the housing adhered to it under the coating on one side. The battery is assembled with what appear to be both brass and steel screws. The working parts (cogs, operating handle, and curved devices which lift the stamps as the handle turns) appear to be made of brass. The housing around the stamps appears to be iron, painted black. Rubber and felt (probably woollen) layers occur underneath the stamps.
