Downstairs in the workshop area can be seen a collection of small steam engines that includes a Bradford horizontal steam engine (seen here), a Sissons single slide valve engine, a Reader single piston valve engine, together with a Weir boiler feed pump,
The horizontal Bradford Engine is later in design than the beam engine and demonstrates a development in steam power as, by removing the large beam, engines became more compact yet still efficient. lt was built in the latter part of the nineteenth century by Thomas Bradford of The Crescent Iron Works, Salford, Lancashire. It was purchased new by the Haydock Lodge Asylum, Merseyside to power their laundry, possibly as part of rebuilding work in the aftermath of a fire in 1884. It was when the asylum was converted into a hotel that the engine was donated to the Mill.
