Bramah's inventive genius displayed itself alike in small things as in great--in a tap wherewith to draw a glass of beer, and in a hydraulic machine capable of tearing up a tree by the roots. His powers of contrivance seemed inexhaustible, and were exercised on the most various subjects. When any difficulty occurred which mechanical ingenuity was calculated to remove, recourse was usually had to Bramah, and he was rarely found at a loss for a contrivance to overcome it. Thus, when applied to by the Bank of England in 1806, to construct a machine for more accurately and expeditiously printing the numbers and date lines on Bank notes, he at once proceeded to invent the requisite model, which he completed in the course of a month. He subsequently brought it to great perfection the figures in numerical succession being changed by the action of the machine itself,--and it still continues in regular use. Its employment in the Bank of England alone saved the labour of a hundred clerks; but its chief value consisted in its greater accuracy, the perfect legibility of the figures printed by it, and the greatly improved check which it afforded. We next find him occupying himself with inventions connected with the manufacture of pens and paper. His little pen-making machine for readily making quill pens long continued in use, until driven out by the invention of the steel pen; but his patent for making paper by machinery, though ingenious, like everything he did, does not seem to have been adopted, the inventions of Fourdrinier and Donkin in this direction having shortly superseded all others. Among his other minor inventions may be mentioned his improved method of constructing and sledging carriage-wheels, and his improved method of laying water-pipes. In his specification of the last-mentioned invention, he included the application of water-power to the driving of machinery of every description, and for hoisting and lowering goods in docks and warehouses,--since carried out in practice, though in a different manner, by Sir William Armstrong.[7] In this, as in many other matters, Bramah shot ahead of the mechanical necessities of his time; and hence many of his patents (of which he held at one time more than twenty) proved altogether profitless. His last patent, taken out in 1814, was for the application of Roman cement to timber for the purpose of preventing dry rot.
