Description

Sectional model showing the working parts of a manual fire engine, the Merryweather 'London Brigade' appliance. The pumping machinery consists of two pumps connected with the handles by levers. Water is taken in through the inlet valve, either through suction hose or through the inlet from the chamber containing the pumps, if this can be kept filled by water from a hydrant. From each cylinder water pases through a delivery valve and out through a branched pipe, on which there is a large copper air vesel to secure a uniform discharge.
