"In ...breakages from high speed and irregular pitch, ten out of the eleven wheels had spur segments moulded from patterns, instead of by machinery; and in three of the ten the teeth were cast upon the felks, and were twisted and drawn, as they generally are when cast in this way, by the contraction of the mass of metal of which they form a part. In every instance the speed was high, and in several cases there was more or less backlash or over-running."

"1894 William Westall. Tinkler. Ludgate Illustrated Magazine. Vol VIII Thrutch factory was a queer old concern. It had been built piecemeal-here a bit and there a bit. There were a new end and an old end, the spinning-rooms in the one being light and lofty, in the other low. and gloomy. Looms were shoved in everywhere. There were a "long shop" with three hundred, a "top shop" with a hundred, a "back shop" with fifty-three, and a "little shop" with fifteen. Never was its equal for gearing. Shafts were everywhere inside and out, overground and underground, climbing snake-like up the walls, and boring into the roofs; spurwheels, great and small, whirled, clashed and "backlashed" all over the place."
