The Lumb Speed Recorder
The Lumb speed recorder is a device used to measure and record the speed of the engine to ensure that a steady engine speed was kept whilst the mill was running to maintain consistently high weave quality.

The speed recorder following dirt and oxide removal from the top frame. Replacement glazing is to be added and the aluminium given a final polish. The body has yet to be completed, so still shows the products of corrosion in the form of a white oxide.

The lumb speed recorder temporally connected to the engine the inners of the speed recorder were sadly missing barring the vertical shaft in the middle.
Thanks to a very kind donation by the Bolton Steam Museum who donated a complete Lumb speed recorder that also needed restoration we have been able to use the parts out of it to fit into ours it still requires work but has taken a back seat for the moment whilst engine restoration work is pushed forward.
