Tottenham House

Crofton Pumping Station - preserved boiler front Crofton used to have two Lancashire boilers when I first visited about 1980. It now only has one workable boiler has this example by the Great Western Railway's Swindon works now consists only of this front and a little of the shell behind the wall. The space behind is now used for other, revenue generating, purposes. I might have a monochrome of the boiler when it was still workable.

Crofton Pumping Station First commenced in 1809 to supply water to the Summit level of the Kennet & Avon Canal, this building now houses engines by Boulton & Watt of 1812 and Harvey & Co of Hayle of 1846. These are both workable and the older is the world's oldest in situ engine capable of doing its original job. The open doors lead into the boiler house. The beam engines are in the taller section.

This shows the pump end of the beam engine house with boiler house behind. The bridge in the centre crosses the discharge channel that takes the water from the pumps to the canal's summit level. The summit crosses a watershed and there is no natural supply to make up for lockage losses. The alternatives were a tunnel below the summit or a pumping station to return water from a lower level. The canal company opted for pumping and that is still carried out today with electric pumps.

This shows the discharge channel taking water from the two pumping engines to the summit level of the canal. The canal's summit crosses a watershed where there is no natural supply to replace lockage losses. The canal company had a choice of building a tunnel under the summit or using back pumping from a lower level. They opted for pumping.

Crofton Pumping Station - spare Lancashire boiler This was acquired from a W D & H O Wills factory in Swindon and has been stored in the open air for over 25 years. It was obtained as a spare to the site's 1899 boiler that was obtained second-hand in the 1980s from a W D & H O Wills factory in Bristol. That latter boiler is the site's only operational boiler and in the 2021-22 winter period is to receive some major preventative maintenance that will hopefully see it through the next 10 years. This spare boiler will probably never get used, but who knows.

The heritage steam sector is facing problems with the supply of coal and concerns about using fossil fuels. However, Crofton intends to remain in steam for as long as possible and is considering alternatives such as biocoal. Apart from the business of raising steam, one also has to consider the longevity of machinery that is over 150-200 years old. The engines have been examined by non-destructive testing and their performance and loading is being examined with appropriate instrumentation (some of it from the same stable as the telemetry used in F1 racing).

This shows the 1812 engine's pump rod that operates a bucket pump down the well. At the top it is connected to the beam two floor further up and at the bottom it enters the covered pump discharge launder heading through the far wall. Because it is a bucket pump the rod is within the rising main down the well.

Crofton Pumping Station - off-site engines in the boiler house First commenced in 1809 to supply water to the Summit level of the Kennet & Avon Canal, this pumping station now houses engines by Boulton & Watt of 1812 and Harvey & Co of Hayle of 1846. These are both workable and the older is the world's oldest in situ engine capable of doing its original job. 

In the boiler house is this small collection of steamable engines that are quite unrelated to the pumping station but of interest in their own right. Some are quite old and rare while others help to illustrate the spectrum of stationary engine designs. Not everybody believes they have any place at Crofton but I am quite comfortable with their presence as it is made clear they are interlopers.

These are both workable and the older is the world's oldest in situ engine capable of doing its original job. 

This is the middle floor of the engine house and shows the pump end of the 1812 engine. The beam is red item at the top. The parallel motion guides the pump rod in the background and also the air pump rod in the foreground. Note that the air pump rod has a bridle around one of the transverse links of the parallel motion - an elegant solution to a problem of geometry.

These are both workable and the older is the world's oldest in situ engine capable of doing its original job. 

This is the middle chamber of the engine house showing the two cylinders heads of the Cornish cycle beam pumping engines. The 1846 engine is closest and the 1812 engine is furthest away. The beam of the 1812 engine is visible at the top and its position clearly shows that the engine is running. The hand rails are a modern addition for public safety. This building is over 200 years old and was never built with 21st century public access and safety standards in mind.

These are both workable and the older is the world's oldest in situ engine capable of doing its original job. 

This shows the valve gear of the 1812 engine. This is not the original gear but that dating from the engine's conversion to use higher pressure steam on the Cornish cycle in 1844 by Harvey & Co. of Hayle, Cornwall. The engine is clearly not working as the exhaust valve is being held closed by a chain.

Crofton Pumping Station - oscillating engine An off-site engine displayed in the boiler house. It was running and shows some slight blurring. It is a very rare inverted vertical oscillating cylinder engine by Thomas Horn & Son in about 1883. It was used at Aldershot Gas Works. The cylinder is 8" x 18" and developed 10 horsepower at 120 revolutions per minute. The engine is on loan from the Science Museum. It was acquired by the Science Museum in 1945.

The Science Museum also has a vertical oscillating cylinder engine that is now on loan to the London Museum of Water and Steam (formerly the Kew Bridge Steam Museum).

Crofton Pumping Station - Sunderland Forge & Engineering Co engine One of the workable off-site engines displayed in the boiler house. This is an inverted vertical single cylinder engine driving a dynamo (DC). It was built c1924 by Sunderland Forge and Engineering Co and used on the steam drifter (fishing vessel) Bluebottle. Rated at 2.5kW, 110V at 450 revolutions per minute. Rescued from the vessel in the breaker's yard and presented by Dr A Twort.

This little collection of engines is of interest and shows some of spectrum of stationary steam power. Although its relevance to the site has been discussed, I hope it remains there for the education and interest of the visitors.

Crofton Pumping Station - the working boiler Steam is now raised in this Lancashire boiler by Thomas Beeley & Co of Hyde and built in 1899. This was installed secondhand in 1986 to replace the 1905 boiler supplied by the Great Western Railway's Swindon works. It came from a Will's tobacco factory in Bristol and there is a spare boiler from the same company's Swindon factory. The firehole doors were reused and the brass surrounds state Great Western Railway. The GWR was once the owner of the Canal and pumping station.
