  1. On these locks, the bywash originally ran through a culvert, with weirs fitted behind both gates, as shown below.
  2. Selby railway bridge over the Ouse used to have water pipework to cool the bridge in hot weather. In the 1890s, one of the designs for boatlifts on the proposed Danube-Oder-Elbe Canal was for a large circular revolving lift to take the 1000 ton standard German boats of the time. It was rejected as it was thought that with the sun on one end only, the other being in the shade, it would seize up due to differential expansion.
  3. The term 'long boat' is used in regard to L&LC craft to differentiate them from the 'short boats' which could work over the summit. The A&CN made the same differentiation between boats that could, or couldn't, work onto the C&HN. The advert seems to have been written by a southerner, a group which has devastated the north economically, just as the Vikings did when they came over in their longboats centuries ago.
  4. I know that there will have to be a public inquiry, but wouldn't the money it will cost be better spent on upgrading existing housing stock immediately. It does seem to be the failing of our economic system that no one seems to have an overall financial view, and that the benefit of some social services and works cannot be addressed in the simple financial terms we use today. Our financial markets and systems are akin to gambling, so some people will always be losers.
  5. George, in 1986, passing the bone works at Appley Bridge. Where were you Tim! You should have had the bridge ready.
  6. The drawing doesn't show it, but the barges were flat bottomed, as were some on the Severn Estuary.
  7. I think this was one of the boats, sunk on the estuary in 1982.
  8. It is interesting that at least one of John Smeaton's original designs for locks on the F&CC included upper ground paddles, and another drawing had waste water weirs fitted into the gate recesses. I wonder why they were not used when built. The ground paddle does look as if it could be removed without leaving much trace, so that may have happened, although other Smeaton plans for the locks do not show ground paddles. It must be one of very few canals not to use them.
  9. The Bavarian and Austrian ones were probably more important to the state as they were supplying the respective capital cities and other areas with wood for heating and industry, so consequently built in a substantial manner.
  10. This was a system widely used in Bavaria and Austria, particularly for firewood. There seem to be several Triftklause, the dam and gate, surviving. Below is one I visited in 1995. There were also narrow canals for logs, the best known being the Schwartzenburger Schwemmkanal on the border between Czech Republic and Austria which includes a tunnel,seen below, as does one I have recently been told about to the south of Vienna.
  11. I think Water Wanderer was A&CN Flyboat 99, built in 1879 and lengthened in 1913. Fair Maiden may have been A&CN 95, also 1879 and C&HN size, as was A&CN 68 of 1876, which may be June, and A&CN 85 of 1878, which may be Pauline. The three L&LC boats were Humber (Water Gypsy), Wharfe (Water Prince), and Aire (Water Princess), the later two being shortened to work on the C&HN. David Lowe recently sent me the details regarding the L&LC boats.
  12. It certainly does, with the wealthy in this country supporting financial institutions which are maintaining a slave trade, in much the same way as happened 250 years ago. Vote tory to support institutions which are ensuring that many workers around the world are paid little, the same institutions ensuring that industry here does not provide skilled training for British workers so that they can encourage lower paid immigrant skilled workers from abroad. Nothing changes, apart from greed increasing.
  13. The airhole/spillway on Stubing Lower Lock
  14. I don't think they ever had bywashes, excess water being led through a spillway, or airhole, behind the lower gate and into the paddle culvert. All the locks on the Yorkshire side had this system, and conventional bywahes were only fitted to the locks from around Littleborough, which were the last to be built. The Manchester locks were built earlier as a link to the Ashton, so had the integrated bywashes, which rely upon the correct height of head and tail gate to operate properly. The head gates need to be slightly lower than the spillway, while the tail gates need to be slightly higher.
  15. I have a photo of her as a house boat at Thorne in 1975. By 2000 she was on the bank at Sheffield and became a restoration project for training young people. Unfortunately, those in charge do not seem to have appreciated the skills necessary, and the work undertaken was of very poor quality. I was asked to look at her in 2004, by which time she was probably in too poor a condition for restoration, though I did make an extensive photographic record. I think she must have been broken up shortly afterwards.
