Introduction

These engines were built early in the nineteenth century for use at Wychall Mill in Kings Norton, Birmingham. The mill rolled sheets of copper for everything from cutlery to gun cartridges. Before the engines were installed, a water wheel was used to power the rollers. As demand grew, extra rollers were added but the watermill could not provide enough power. The owner added the large steam engine in 1820s and the smaller one in the 1840s. They continued in use at the mill until it was closed down in 1943.

History

Water was important source of power around Birmingham. In 1860 there were 60 watermills within six miles of the town. Wychall Mill in Kings Norton was converted from a flour mill to a copper rolling mill in the late eighteenth century. In the early days the mill was used to roll Sheffield plate, but also produced copper for cutlery around 1900, or gun cartridges during the Second World War. The steam engines were installed to ensure that a constant supply of power was available for the substantial amount of machinery. It remained in use until 1943.

Since the eighteenth century, Birmingham has been a renowned centre of the manufacture of a huge range of metal goods. Rolling mills produced the large sheets of metal from which hundreds of different items could be cut. The metal was used to make pen nibs, bicycles, buttons, whistles and guns. The skills of the workforce, together with the innovation and adaptability of the companies were legendary. The diversity of materials employed — brass, copper, silver, aluminium or later stainless steel — was also enormous. Great quantities were sent all over the globe, ensuring Birmingham's reputation as the 'Workshop of the World'.
