| The 1871 encyclopedia The Technical Educator has an article that itemizes Bramah's inventions. "In the year 1806 Bramah contrived an exceedingly ingenious mode of printing, which was shortly afterwards applied to the numbering of bank notes, and by the introduction of which, during the issue of one-pound notes by the Bank of England, the labour of 100 clerks out of 120 was dispensed with. This machine consists of a number of discs, or wheels, with the numbers from 1 to 9, and 0 cut upon the periphery of each, the whole being mounted upon one axle, but capable of turning independently of each other. By the action of mechanism, which is incapable of error, the position of one wheel of the series is moved between each operation of printing, so that when the machine is properly adjusted it will print a series of numbers in regular progression, without the possibility of twice producing the same number." |
