“Well,” remarked Mrs M, after contemplating it for some time, “it don’t look very like scissors, but I’m free to confess that them two bits of iron do act much in the same way.”
“And with the same result, Missus,” observed the machine-man, putting the plate between the clippers, which, closing quietly, snipped off about a foot of iron as if it had been paper. There was, however, a crunching sound which indicated great power, and drew from Mrs Marrot an exclamation of surprise not altogether unmingled with alarm.
The man then seized a bit of iron about as thick as his own wrist—full an inch and a half in diameter—which the scissors cut up into lengths of eighteen inches or so as easily as if it had been a bar of lead or wood.
“Didn’t I say it could cut through the poker, mother?” cried Bob with a look of triumph.
“The poker, boy! it could cut poker, tongs, shovel, and fender, all at once!” replied Mrs Marrot—“well, I never! can it do anything else?”
In reply to this the man took up several pieces of hard steel, which it snipped through as easily as it had cut the iron.
But if Mrs Marrot’s surprise at the scissors was great, not less great was it at the punching machine, which punched little buttons the size of a sixpence out of cold iron full half-an-inch thick. This vicious implement not only punched holes all round boiler-plates so as to permit of their being riveted together, but it cut patterns out of thick iron plates by punching rows of such holes so close to each other that they formed one long cutting, straight or crooked, as might be required. In short, the punching machine acted the part of a saw, and cut the iron plates in any shape that was desired. Here also they saw the testing of engine springs—those springs which to most people appear to have no spring in them whatever—so very powerful are they. One of these was laid on an iron table, with its two ends resting against an iron plate. A man approached and measured it exactly. Then a hydraulic ram was applied; and there was something quite impressive in the easy quiet way, in which the ram shoved a spring, which the weight of a locomotive can scarcely affect, quite flat against the iron plate, and held it there a moment or two! Being released, the spring resumed its proper form. It was then re-measured; found not to have expanded a hair’s-breadth, and, therefore,—as Will Garvie took care to explain,—was passed as a sound well-tempered spring; whereat Bob remarked that it would need to be a good-tempered spring, to suffer such treatment without grumbling.
It seemed to Mrs Marrot now as if her capacity for surprise had reached its limit; but she little knew the wealth of capacity for creating surprise that lay in these amazing “works” of the Grand National Trunk Railway.
The next place she was ushered into was a vast apartment where iron in every shape, size, and form was being planed and turned and cut. The ceiling of the building, or rather the place where a ceiling ought in ordinary circumstances to have been, was alive with moving bands and whirling wheels. The first thing she was called on to contemplate was the turning of the tyre or rim of one of the driving-wheels of a locomotive. Often had Mrs Marrot heard her husband talk of tyres and driving-wheels, and many a time had she seen these wheels whirling, half-concealed, in their appropriate places, but never till that day had she seen the iron hoop, eight feet in diameter, elevated in bare simplicity on a turning-lathe, where its size impressed her so much that she declared, “she never could ’ave imagined engine-wheels was so big,” and asked, “’ow did they ever manage to get ’em lifted up to w’ere they was?”
To which an overseer kindly replied by pointing out a neat little crane fitted on a tail, which, when required, ran along the apartment like a strong obedient little domestic servant, lifting wheels, etcetera, that a man could scarcely move, and placing them wherever they were wanted. Mrs Marrot was then directed to observe the rim of the wheel, where she saw a small chisel cutting iron curls off it just as easily, to all appearance, as a turner cuts shavings off wood—and these iron curls were not delicate; they were thick, solid, unpliant ringlets, that would have formed a suitable decoration for the fair brow of a locomotive, or, perhaps, a chignon—supposing that any locomotive could have been prevailed on to adopt such a wild monstrosity!
