From Graces Guide
123. WEIR, EDWARD, 351 Oxford Street — Inventor and Manufacturer.
Irrigator liquid manure pump, fire, and garden engine, with hose and hose reel. As a fire-engine it will throw 20 gallons of water per minute to a height of 40 feet from the end of the nozzle.
Improved draining level; the level is found by means of the spirit tube. It stands on three legs, requiring no driving into the ground or fixing, and when once adjusted to its level by means of the regulating screws, it may be turned in any direction; the most convenient fall or outlet for the drain may then be easily found, without the instrument requiring any readjustment. The index tells off immediately the rise or fall in inches, in every yard.
