Muscle mills

This is a new section for me covering mills that were operated by either humans or animals which I hope to add to and eventually when I have sufficient I will create separate pages for the different types.

Mainly the drawings have been prepared from old advertisements, drawings, photographs and descriptions in books etc, although the Romanian ones are based on scale drawings of buildings that have been relocated into the Astra Museum at Sibiu in Romania. A fantastic site and well worth visiting




		The stepping mill above was for the Bedford Prison or ‘House of Correction’ and was used to grind corn into flour and also powered a set of malt rollers

This is a horse powered corn mill in the Astra National Museum complex at Sibiu in Romania. The drawings I have worked to do not show that the one end of the driving ring gear overlaps the tail end of the previous section so they parts are staggered. A colleague who had visited the site from the Mills Research Group pointed it out to me. I shall be visiting the museum again in September so I shall pay particular attention to this detail and adjust my drawing accordingly. The winch on the platform tilts the main vertical post so the ring gear touches the floor to allow the horses to step over it when entering and leaving.


	This dog wheel was used to power a centrifugal blower


	This dog wheel was used to operate a set of bellows


	These three drawings are loosely based on a book about dog mills called ‘Hondenmolens’ by Jan Delacour in Dutch but very interesting

		The angle of the track for the treadmills shown below is adjusted to suit the weight of the animal and the work it is required to do. The power available from a treadmill is dependent on the weight of the animal and the angle of the tread, not on the strength of the animal. The dog simply climbs the tread to maintain his position and gravity does the work..


	This dog wheel was used to provide rotary power for a butter churn


	This treadmill operates a horizontal rocking butter churn


	This treadmill was used to provide power for a butter churn


	This treadmill operates a lathe but could power any rotating piece of machinery

This is a horse powered sawmill at the Astra museum in Sibiu below is manually operated grain mill at the same museum

One clever designer in the Victorian era came up with a sewing machine powered by a dog. German inventor Heinrich Feldt designed and patented The Feldt Dog Engine in 1888, and intended for it to offer seamstresses a bit of relief when it came to mending and sewing clothing

There are many more types of mill to add so watch this space
