In 2009, the society was contacted by Glyn Phillips of BW regarding an artifact at the Ellesmere Museum. A pump that was once in the pumphouse when it was restored only ten years ago. At that time the pump was taken to Ellesmere Museum for safe keeping as a possible exhibit. The request was for the pump to return to the BCN, Titford and the pumphouse as the museum was down sizing its exhibits.
Wow everybody thought a beam engine, well in reality it is to the casual observer just a lump of case iron and a series of pipes and an electric motor, all rusting having never been really used as an exhibit. The complete unit manufactured by Sulzer Limited was fitted into the pumphouse in the early 1960's being removed in early 2002. The arrangement was removed from the pump house and the sump at the bottom of the shafts beneath the engine house.
Never the less it was agreed we should have it and think of a way of displaying it, maybe on the Green near the new wier with cut down pipes, and a information board stating its purposes, ie much thought for the council members.
The main problem is collecting it as it probably wieghs a couple of tons, and is in Ellesmere. In a weak moment someone floated the idea of collecting it by water using ATLAS. Well this was thought a great idea by the museum and others as it would attract publicity.
April 2009: Atlas went up to Ellesmere and joined in a cavacalled of working boats as well as loading all the bits of the pump.
Well Atlas brought all of the bits back to the BCN and Hawne. For some time the assembly remained in Atlas as everything was just to heavy to lift out and anyway it ballasted her down nicely. Eventually all was removed and it now sits at Hawne Basin awaiting restoration.
Looking at the bits the main casting is just the ground level mounting casting onto which an electric motor was mounted. This drove a shaft that passed thro the casting and into the vertical tubes. Various bearing brackets supported the shaft as it extended the full lenght of the tubes for some thirty seven feet six inchs down the vertical shaft below the Pump house floor.
At the bottom of the tube that sat in the well of the vertical shaft beneath the pumphouse was an impeller section driven by the shaft. Although we have not got it the flange on the bottom of the impeller section would indicate that some sort of filter or strainer was fitted to prevent heavy objects being sucked in.
Water would be sucked up the tubes by the impeller to the ground level casting where a outlet section of the casting caused the water to pour out into a sideways facing tube.
See below for more detailed photos of the bits as they arrived from Ellesmere.

So any display of the pump assembly will have to included the electric motor, casting and a representation of the tubing with the impeller on the end.
In the photos below the chalk marks indicate the lenght of the tube that would remain and on the impeller section the area of tube cut away to expose the shaft.
Even when cut down by my reckoning a vertical display of some weight will remain and about 8ft tall, that will require a substantial frame to support it, where to put it, watch this space.

August 2009: Further to the above information work has started to halt the march of time and rust with all parts being cleaned then treated with an anti rust solution, then undercoated.
Amazingly we attempted to get to the end of the impeller by removing one casting, expecting a battle with the rusted bolts. But they virtually flew off and the blades of the impeller where exposed. It will require the next series of bolts to be tackled to look further into this head as I for one cannot get my head around that this small blade is responsible for the 833 gallons/min flow, it maybe that like on a jet engine a secondary set of impellers sit in the housing behind the exposed fan. Looking at the bolts on the next casting the battle may be really joined.
|
|
August 2009: Well the next day battle ensued with plenty of release oil, great big spanners and a even bigger set of silsons the above casting bolts came un done. This revealed that as thought a second set of blades are housed behind the first set. These probably act as compressor blades to force the water up the tube.
The impeller would not fully come out of the housing and appeared to be held at a bearing housing some eight feet from the impeller.
To this end part of the tube was cut away just above the bearing assembly to reveal the bearing.
Each lenght of tube is threaded at each end, and a bearing assembly (a casting) is screwed into each end. The shaft to seems to be in lenghts that fit together above each bearing assembly. The end of each shaft is tapered with a key way in it and fixed to the next shaft by a tube that has an inner taper and threaded ends having a threaded boss in each end that locks the tapers.
This would make sense as when it was first assembled, the impeller section with the first lenght of tube and shaft could be lowered down the shaft, then each new lenght of tube/bearing and shaft screwed into the lower assembly until the full lenght was assembled, when it could be attached to the motor unit.
|
|
September 6th 2009: The impeller casting has been sectioned to reveal yet more detail of the impeller section. The casting has internal vanes that probably act as further compressors to force the water up the tube. A quick calculation makes a ten inch diameter of water around forty foot tall would weigh in excess of 3 ton so the impeller would have to be very efficient.
Shown just a first thought/drawing of what it all may look like when finished.
|
|
September 9/10th 2009: Work continued to cut the tubes into finished lenghts. A complete bearing section was cut out of the tube and then sectioned to reveal the casting and bearing/shaft assembly. The top flange was cut from the top section of the tube the last section to be removed from the tube. The majority of which can now be wieghed into a scrap dealer to raise funds for the work to date?.
The attached photograph shows the tubes that when finished will be welded together to represent all the componants of the forty foot long tube condensed into around four feet.
This assembly will then be bolted to the underside of the main casting, which in turn will be mounted onto the frame legs.
Next the shaft was cut to lenght so it can be joined up in the assembled units. Next job is to generally clean up the tubes and castings and paint. Make a representation of the strainer that must have been on the impeller inlet, then bolt and weld the sections together to determine the lenghts of the legs of the frame.
The photograph of the units together is the proposed display of the tubes and the impeller before being cleaned up and painted.

October 11th 2009: Work has continued but at a slower pace. The tube/impeller section has been welded up to its finished lenght just minus the strainer. All off the cut out sections lined up and as can be seen on the photogragh has been lined up and placed onto the mounting casting. The whole assembly is upside down, awaiting the four frame mounting legs that can now be cut to lenght prior to the whole assembly being made ready for painting.
|
|
|
October 28th 2009: The frame has now been completed. The legs of the frame are made from metal tubes dredged from the bottom of Hawne Basin a number of months ago. Checked and tested the thickness of the wall of the tubes is still great so they have be used, yet one more piece of history built into the display. Lenghts of the pump shaft have been cut to lenght and brace the frame, with a cut away joint, detailing the method used to join the shaft included.
The frame has now been seperated from the display and when the site is finally choosed it can be taken to the site and concreted in to await the rest of the display when finally painted.
|

|
November 8th 2009: Have only had one day to give to this project lately, finish off all of the welding on the frame, removed same from the castings and have just started to paint the whole assembly in black hammerite, with the internal surfaces being white.
The motor has yet to be fully looked at, still has its windings and rotor, that added a lot of wieght and as they are constructed manly of copper give scrap thieves a reason to attack the display. So the copper will be removed as this will not detrack from the final visual display and remove any reasons to attack the pump for any scrap value.
|
December 3rd 2009: Photographs below show for the first time the casing and frame put together the right way up. Everything fits and the final effect of the display begins to be seen. The motor has been taken apart and all the copper windings removed, just a bit more painting to pick out some of the componants. The frame will be fixed into a concrete base that will come up to the bottom of the central strainer just below the bottom of the impeller casing.
The unit has been given a first coat of hammerite paint the final coat being delayed until the unit is in place at the Pumphouse.
Just now have to wait for the planning approval to locate the display on the wharf side of the Pumphouse.

Work to fit the New Pumps
|
The two new pumps were lowered down the shafts in June 2003. The pumps unlike the previous arangement are just very heavy electric submersable pumps just like a garden pond pump on the end of heavy duty 3 phase electric cables with a steel cable that takes the main wieght.
Below the pump house is a vertical shaft about 50 ft deep into which the pumps are lowered, the pumps being in a sump at the bottom.
The sump is then connected to the Old Main Line by a brick culvert that runs under the locks.
The culvert had to be inspected to clear a number of blockages, a long and difficult job requiring men with special breathing equipment to complete the job.
The water inlet on the bottom level is right next to Thomas Clayton's old Tar Wharf, and when the pumps where switched on for the first time they pumped up heavily tar polluted water.
This caused the pumps to be shut down and the project to be delayed. This problem was the reason the structures seen in the next section "Problems from the Past" appeared. The problems are today much reduced and in late 2004 the pumps can be run to maintain the level but a watchful eye is kept to see that no pollution occurs.

The pump room has its own crane hoist to lower or raise the pumps.
The 3 phase power supply to the pumps had to be run from the nearest supply that happened to be at the junction of Engine street and Tatbank Road.
This resulted in a trench having to be dug all up Engine Street and across the car park to the site, much of the brick walkway also had to be disturbed.
The cable disappears into the engine house, the controls being housed in the BW mess room, taking up the best part of one wall.
Seems modern technology has reduced the pumps from needing an entire building to just this one small corner.
|

The fitting of the pumps not only required the old culvert to be inspected and put back into use but the complete building of a new spillway and weir near to the top lock.
In this photo the complete island in front of the pump house has become a building site again.
Huge holes were dug and a series of pits and concrete tubes were constructed running from the pump room to a new wier/spill way on the Tatbank branch, near to the top gates of the lock.
Water having been pumped travels along the concrete tubes set beneath the grass area and fills up the spill way, that then controls the flow by emptying over a wier into the top level.
During the first running of the pumps the sump of the spillway filled with tar causing the pumps to be shut down.
All this building work had to be finished in time for a Rally in July 2003.
The work was just completed except for the pumps, and the old fence was replaced with a new fence that depicts boatmen from the past throwing coal from their boats to the local children.
Some suggest it depicts the missles going the other way more in keeping with modern trends, but we cannot agree with that.

A boundary post obtained by the society has been placed on the green near to the fence, all we need now to complete the scene is a society signpost on the junction of the Titford Canal and the Tatbank Branch.
In old journals the Branch is referred to as the Spon Lane Branch, so should the junction be the Spon Lane Branch Junction?

Early in 2003 BW undertook the job of replacing a number of the old lock gates on the Oldbury Flight of locks.
The new gates that came from the Bradley Workshops were brought to the site by the GU motor boat "Auriga".
She can be seen moored alongside the pumphouse loaded down with just two gates, one new and one old gate that had been removed.

At the pump house the top pound between the locks was drained and the pound and lock filled with scaffolding.
The walls to the pound where inspected and repaired as was the chamber walls in the top lock.
The ash wharf wall at the side of the pump house was found to be leaning out, so was lowered and then completely rebuilt.
At the same time the wharf landing was re bricked and bollards added.

A view from Engine Street Bridge in late December 2003. The major work has been completed and the surface of the towpath just needs to be laid.
The side pounds have been partially cleared as have the wiers and the whole flight has been transformed with all the brick work and gates having been repaired. Above the Top lock the landing stage for the lock was relaid as part of the general re build. The Society had been given some money left over from the orginal "Titford Project" an off shoot of the Coombeswood Canal Trust. Whilst BW and the contractors where on site this money was used to construct a line of mooring rings from the top lock back to the railway bridge and beyond.The line of rings and the general improvements to the area have already improved the facalities for our Rally gatherings and are also being used by visiting boats to the area. Money well spent on improving the canal corridor, the aims of the "Titford Project" set up all those years ago.

This possible project is in the embro stage with the Society just looking at the problems and solutions and the likely benifits such a project would bring to the BCN, the local community and enviroment.
The Wednesbury Oak Loop known also to modern boaters as the Bradley Arm presently leaves the Main line at Deepfields Junction
and terminates at the BW Bradley Work shops at Tup Street Bridge.
The bridge carries Bradley Lane and today has no hieght to let a canal pass under, it must have been a steep hump backed bridge in the past.
This is really the only main obstacle to a canal restoration project that would create a cruising ring and greatly improve & re generate a section of the BCN.
Beyond Tup Bridge is a factory complex with the path of the canal running through its yard into public open land.
|
|
|
|
After the factory the bed of the canal enters a public area with tethered horses grazing. From the lye of the land today the canal seems to come to a junction where the canal turns in the gentle bend towards the locks, whilst in the other direction it goes into a large loop.
This loop appears to re join the main bed near to the position where the top lock once was.
At the top lock the top cappings to the walls can just be seen, the entire lock and flight of locks having been in filled with a public path marking the route of the canal.
The lock chambers that are buried appear to be intact with no buildings or structures on the route.
|
|
|
|
The path follows the route between houses, rising and falling indicating where possibly each lock was.
Towards the bottom new houses front the route of the canal but don't impede.
The path finishs at Great Bridge Road, where the ground today is at the same level as the road.
On inspection the bridge has been bricked up and on the lock side filled in, but it would appear that if dug out passage under is possible.
On the opposite side of the road the bricked up section of the bridge can be seen, with a culvert maintaining land drainage.

Below the road a different scene can be found. The bottom two locks and their approach walls have been restored by BW and then in filed to protect.The canal corridor ie tow paths etc, from here to Moorcroft Junction have been tidied up and turn into a pleasant walkway.
Cycle barriers have been installed the only thing missing being an open ribbon of water.
The canal bed consists of a small channel of water that would be impassable even to the smallest boat.
Reeds shoulder high along the complete section, fill the canal until Moorcroft junction and the Walsall Canal.

As can be seen the work involved in digging out the line is massive. But no real obstacles compared to other restorations really exist.
The bridge problem at Tup could be solved by a lift bridge as it would be impracticle to put back a normal bridge.
Bradley Lane is a bit of a rat run, with traffic calming measures that seem to be popular these days being considered.
A lift bridge would certainly calm traffic speed, with posible funding coming from that area?.
The factory yard is owned by BW the canal could cause the area to be re generated.
The rest of the canal is a digging out operation in the first instance with no building or land ownership problems.
It would not or could not be achieved by this society alone but the scheme could be viable with the right funding.
The pumps at Bradley empty water from the mines below so no water shortage problems exist.
The mine water contains high levels of iron, that today are seperated by dilution and settlement in the Bradley Arm.
The re instating of the Loop just before the locks could create a large settlement area not used by boats, but full of reeds and wild life.
All of these ideas and problems will need much thought and consultation but do not see to be insurmountable.
The society will play its part alongside BW, by talking to other interested parties in the funding area, and by creating local interest in the project by pointing out the enviromental value and re generation possiblities.
It can be seen that some restoration work has been carried out on the bottom locks by BW who are to be congratulated at getting the project off the ground. It's up to as many people as possible: to get involved and see if more can be achieved.
