it was arranged that Bacquancourt should introduce him, which he did, and after the interview which took place Brunel promised to call again with the drawings of his proposed model.
A few days passed, and Brunel called with the first drawing, done by himself; for he was a capital draughtsman, and used to speak of drawing as the "alphabet of the engineer." The drawing only showed a little bit of the intended machine, and Brunel did not yet think it advisable to communicate to Maudslay the precise object he had in view; for inventors are usually very chary of explaining their schemes to others, for fear of being anticipated. Again Brunel appeared at Maudslay's shop with a further drawing, still not explaining his design; but at the third visit, immediately on looking at the fresh drawings he had brought, Maudslay exclaimed, "Ah! now I see what you are thinking of; you want machinery for making blocks." At this Brunel became more communicative, and explained his designs to the mechanic, who fully entered into his views, and went on from that time forward striving to his utmost to work out the inventor's conceptions and embody them in a practical machine.
While still occupied on the models, which were begun in 1800, Maudslay removed his shop from Wells-street, where he was assisted by a single journeyman, to Margaret-street, Cavendish-square, where he had greater room for carrying on his trade, and was also enabled to increase the number of his hands. The working models were ready for inspection by Sir Samuel Bentham and the Lords of the Admiralty in 1801, and having been fully approved by them, Brunel was authorized to proceed with the execution of the requisite machinery for the manufacture of the ship's blocks required for the Royal Navy. The whole of this machinery was executed by Henry Maudslay; it occupied him very fully for nearly six years, so that the manufacture of blocks by the new process was not begun until September, 1808.
We despair of being able to give any adequate description in words of the intricate arrangements and mode of action of the block-making machinery. Let any one attempt to describe the much more simple and familiar process by which a shoemaker makes a pair of shoes, and he will find how inadequate mere words are to describe any mechanical operation.[13] Suffice it to say, that the machinery was of the most beautiful manufacture and finish, and even at this day will bear comparison with the most perfect machines which can be turned out with all the improved appliances of modern tools. The framing was of cast-iron, while the parts exposed to violent and rapid action were all of the best hardened steel. In turning out the various parts, Maudslay found his slide rest of indispensable value. Indeed, without this contrivance, it is doubtful whether machinery of so delicate and intricate a character could possibly have been executed. There was not one, but many machines in the series, each devoted to a special operation in the formation of a block. Thus there were various sawing-machines,--the Straight Cross-Cutting Saw, the Circular Cross-Cutting Saw, the Reciprocating Ripping-saw, and the Circular Ripping-Saw. Then there were the Boring Machines, and the Mortising Machine, of beautiful construction, for cutting the sheave-holes, furnished with numerous chisels, each making from 110 to 150 strokes a minute, and cutting at every stroke a chip as thick as pasteboard with the utmost precision. In addition to these were the Corner-Saw for cutting off the corners of the block, the Shaping Machine for accurately forming the outside surfaces, the Scoring Engine for cutting the groove round the longest diameter of the block for the reception of the rope, and various other machines for drilling, riveting, and finishing the blocks, besides those for making the sheaves.
