John Lovell, Once a Week (1863)
“ Other pairs of rollers, with their attendant workmen, are doing similar work on every hand; and here and there are immense pairs of shears, whose crocodile jaws are for ever in motion. A piece of metal, an inch thick, is thrust into them, and they bite it asunder; a piece of pin-wire, and they snip it off crisp and clean as a pair of cutting pliers. Huge hammers there are, too, that strike, as the wheels turn and the shears bite, by some agency unseen, but in the extent of its power terrible—hammers that will smash a red-hot cannonball flat, or crack a nut without bruising the kernel. ”
