1851 Great Exhibition: Official Catalogue: Class IX.: William Brodie
98. BRODIE, WILLIAM, Airdrie, Scotland.
A registered drain-tile and pipe-machine. This machine is driven by steam or horse-power, and when wrought at a speed by which two women take away the pipes, makes from 10,000 to 12,000 two-inch pipes per day. By putting the rope which is attached to the driving- power on a smaller pulley, to bring up the speed, the produce is from 12,000 to 18,000 pipes in 10 hours. Various sizes of tiles and pipes, for leading drains, can also be made when required. By putting on a set of grating dies, this machine is capable of cleaning the stones from clay, after passing through a pug-mill, sufficient to make from 16,000 to 20,000 two-inch pipes per day.
