Several of the tie bars were found to be broken on this stoppage occasion, when the lock wall suddenly moved by 6 inches overnight. The tie bars were all renewed to steel bars with bottle screws, so that they could be re-adjusted in future if nessecary. There are 2 sets of tie bars at different heights on each vertical beam, and they are anchored to massive baulks of timber running the full length of the lock.
The picture shows towpath side, but some years later a test dig was made on the offside wall, as this was leaning in somewhat. This revealed totally sound tie bars (non-adjustable) anchored to a railway line longitudal structure. As it was all sound, it was deemed best to leave well alone. Hence this wall is still leaning, due to the sand hill.
I can confirm that the gate paddle was fitted due to the slides on the ground paddle having corroded away, making it in-operable. This was sorted later when the new wooden gates were installed 2013.
Incidentally, the current overflow weir is not original but added later. The original was on the towpath side, where there are 3 slots in the iron wall in the headbay area, with an iron pipe emitting below the lower landing stage.
The staircase locks would have been further back, probably fairly close to the cottage.
The driveway across the field to Stone Lock is along the original canal bed.
Before the "accessible" towpath ramp was built there was a distinct curve in the towpath hedge where the towpath swung round a fairly sharp curve after leaving the staircase locks to get under the (smaller in those days) bridge.
If anyone has any pictures of the old canal bridge here, from canal level, or of Beeston Wharf, I would be very interested to see them. There are several pictures from road level showing both old and 'new' bridges available.
