The Sheffield & Rotherham Independent, Saturday, February 9, 1884; page 5, Issue 9152
If you were a file grinder in nineteenth century Sheffield, then you probably rented one or more troughs in one of the many wheels located throughout Sheffield. Each wheel consisted of rooms called hulls and each hull had a number of trows or troughs. The trough was made of cast metal and contained the water in which the grinding stone revolved. Each trough had divisions for the grinding stone, the glazer, the lap and the polisher. In the back of the room was a drum or wheel, normally driven by a steam engine and wheel bands from it were used to drive the grinding stone, the glazer, the lap and the polisher.
Sometimes a file grinder would sublet troughs from a hull or sometimes he would rent a hull and employ apprentices to work in the other troughs. File grinding could pay relatively well; with some earning as much as 27 to 35 shillings a week in the mid nineteenth century but it was a hard job. Men who worked as file grinders, especially those who worked at ‘dry grinding’ often developed grinder’s phthisis, a common term for any one of a number of lung diseases and many did not live beyond their thirtieth birthday. Those who did not die from severe respiratory ailments at an early age were debilitated by them and few were able to work beyond the age of fifty.
Boys, often sons of grinders, as young as seven or eight were employed in the Sheffield wheels and their young lungs were particularly susceptible to the dust. They were usually employed in polishing and frequently suffered from coughing and shortness of breath. In this way, many families lost generation after generation to the file grinders’ trade.
Injury, too, was common place amongst file grinders. Rapidly spinning wheels were sometimes known to shatter, flinging stone everywhere. Most file grinders had been struck many times by the debris, and often sustained cuts and bruises, lost teeth and sometimes were even killed.
