Steam pressure gauge made by instrument makers Chadburn Bros of Sheffield, 1856-1862.

In this gauge, patented by Mr. A. Chadburn in 1856, the pressure to be determined is measured by the amount of bulging it causes in a flexible disc of sheet metal, secured round its edge to a circular box into which the fluid is admitted. The slight movement obtained is multiplied by levers that transmit it to the index.
