Entrance to the Mill
Entrance to the mill is via the Mill Shop which sells gifts, toys
Thwaite House - The Mill managers home & office.
Thwaite House is is a Grade 2 listed building and a great Georgian hone built in 1823. It is located immediately after the entrance Shop and 40 metres before the first entrance into the mill.
Only the ground floor is open to the public and it is a museum and lade out as a typical home during the early 20 th century including the war II
There are 5 rooms on the ground floor.
- The kitchen. At this period was often the main living room in many homes in this period of time, especially in winter before central heating.
- The washing room, a smaller room off the kitchen. Can only be viewed from the doorway.
- The Sitting room, in this period often only used on Sundays or when visitors were expected.
- The Managers Office
- A room for your kids to play in.
An early Vacuum Cleaner from around 1907, made in Britain to a French design.
The cleaner was hand powered and required 2 people to operate. One would operate the broomstick sized handle that opened & closed the bellows creating a suction. The other person operated the nozzle
Early electric vacuum cleaners were also available at this time but electricity was not readily available and people were frightened of electrocution., therefore they were not popular.
The cast iron Yorkshire Range was the backbone of the kitchen. It was the only cooking source, having an oven for bread & cake making & Meat roasting. Stands that held pans over the fire and a boiler to supply hot water.
A polish called Black Leading was applied to the range to make them shine & look good.
In winter the iron shelves of the oven were wrapped up and placed in the bed as bed warmers.
The brass housing at the top held a wind up clockwork motor that slowly rotated the joint of meat hanging from it.
Meat juices and fat dripping from the meat ran into a collection pit in the bottom. this could be scooped out with the ladle and placed in jars to cool into dripping & jelly which was used as a spread on bread or used as an ingredient in recipes of the fat used for frying.
During World War II food was rationed therefore nothing was wasted.
Flat irons are used for ironing washing. They are made from cast iron and have a thick base to store the heat for as long as possible. Most house holds would have more that 1 flat iron so that while one is being used the others would be getting hot placed on a plate directly over the fire. The large brass flat iron at the front is hollow with a hinged top. Hot glowing coals from the fire would be placed inside. Electric irons were available where households had electricity.
The long poker looking object is a hair curling tool.
To one side of the kitchen is a doorway and a few steps down leading to a washing room. Just to the right of the door is a manual operated washing machine. the first electric one came out in 1908.
At the far side of the room is an older method a washing tub, to the left of the chair, where the washing was manually agitated in a washing tub with either a:
- Washing dolly a long handle with a cross handle at the top & 3 or 4 prongs on the bottom. Used in a twisting motion usually on sturdy items..
- A posser, similar to the dolly but with a semi sphere at the bottom used in a plunging up & down motion, used usually on light weight washing, such as cotton sheets & shirts..
A Washboard, to the right of the chair, was a frame with a corrugated iron centre against which the washing was rubbed. Later in the 50's became an instrument in Skiffle Bands.
In the far right corner is an open top copper boiler in which clothes were boiled. a fire was lit under the boiler, you can just see the fire door behind the washboard
Leaning against the back wall is a wringer. On it's left side is a crank wheel that revolved the 2 large wooden rollers through which wet clothes where passed squeezing out the water. The gap between the rollers could be adjusted by the 2 large wing nut on the top and gap tension was retained by strong springs hidden by the frame
A manually operated washing machine Through the lid is a spindle with a dolly inside that agitates the washing, a turning handle outside operates the dolly. On top on one side of the machine is a wringer to squeeze out the water.
Before modern detergents a product called Dolly blue was dipped into the rinse water. The blue in the water dyed the washing very slightly and masked the yellowing of white goods.
Some of the notable features of the this Sitting room are:
- The large rug made from rag clippings
- Clockwork wind up Gramophone for playing 78 RPM records.
- Wooden Clothes Horse over which clothes were dried.
- Flat iron on the ironing board.
- Lace table cloth
- Tea cosy over the tea pot
Another partially raised rag rug is hanging up and the canvas backing can bee seen. Rag clippings were looped through the canvas using a special latch hooked piece of metal similar to those used for crochet.
The Mills Managers Office had a roll top desk. Various business, account & information books are located on the desk and on shelves in the room.

The Working Mill
The weir is basically a dam across the river and deepens it providing a head of water to power the waterwheels. Excess water flows over the top of the weir
Hinged Wooden boards called deals placed on top of the weir could be raised to increase the head of water. These are lowered when the river is in flood.
At the end of the weir is a gate that can be opened to bypass the weir & the mill and lower the water behind the weir. This allows repairs to be conducted on either the weir or the deals.
Thwaite mills has 2 undershot waterwheels with diameters of 18feet (5.6m) and widths of 14.5 feet (4.26m) & 8.75 feet (2.67m) wide, to power the various machinery. Later they purchased a diesel engine. The waterwheels have a maximum turning rate of 12 rpm.
An undershot wheel is where the flow of water runs under the wheel. This method is not as efficient as the overshot wheel where water is introduced to the top of the wheel where the weight of water in the wheels paddles adds to the force of the flow.
The wheels rotation speed could be controlled by the amount of water flowing through 'Sluice gates' which could be closed to stop the wheel. The water then flows back to the river via the tail race which flows between the Workshop & Drying Sheds.
The waterwheels each rotate a horizontal shaft that provides power to all the machinery via shafts, cogs, gears, belts & pulleys
This pair of right angle cogs change the direction between vertical and horizontal rotation. In addition the handle wheel on the right side of the right cog moves to cogs so that it can be disengaged to stop the attached machinery.
Because the cogs are of different diameters the shafts will rotate at different speeds
Belt & Pulleys
Belt & Pulleys are used to transfer power from the shafts to other shafts connected to some of the machinery. With a half twist in the belt they could transfer power between horizontal & vertical rotation
Being located just under the ceiling leaves the floor clear for the passage of workers and/or for machinery
A drip tray is located underneath the bearings to catch excess grease
Rock Chalk on top of a roller crushing machine where it's crushed to small pebble size pieces before transported further into the mill
The mill could also crush Flint rock if required.
The Edge Running Mill is where the chalk is ground to powder. in the presence of water which mixes with the powdered chalk to form a slurry which overflows into a series of settling pits. Giant paddles slowly stir that water keeping the finer chalk to remain in suspension in the water and overflowing to the next pit. The larger particles of chalk quickly settle to the bottom where this 'lumpy' slurry is pumped back to the Edge Running Mill for additional grinding.
Chalk from the final pit is recovered & transported to the drying rooms in a separate building to be dry to a chalk powder.
The chalk powder was then sold, or was mixed with linseed oil to form putty used to fix in glass windows and then sold.
The Horizontal Auger works on the Horizontal Archimedes screw principle & is a method of transporting rock chippings between machinery. Normally this is done in an enclosed tube but the top half of the tube has been removed to allow visitors to see the screw.
Here the rock chippings are being elevated to the The Edge Running Mill via an elevator comprising of a moving sloping belt, set in a channel. Wooden blocks attached to the belt, prevent the chippings from slipping back down the elevator.
Whiting ie powdered chalk in sacks & also spilt upon the floor. Whiting
was either sold as a product or it went for further processing to make putty on the first floor.
The woods, grounds and island are a haven for wildlife. Visitors should walk around slowly and quietly and look out for kingfishers, herons, foxes, rabbits, woodpeckers, waterfowl and many more creatures
