The photo will, I hope, be of interest to seafarers and marine engineers.
The steam wood constructed City of Bristol (built 1827 of 218 tons 143 x 23 depth of hold 15ft) went ashore in Rhossili Bay, Gower, Wales on Wednesday 18 November 1848 in gale conditions on passage from Cork Ireland to Wales and on finally to Bristol. On grounding, she broke up sustaining loss of life of the crew of 25 and some five passengers. Only two persons survived, together with a number of cattle and pigs that managed to swim ashore.
The photo shown is of a valve and copper pipe but of particular note is that the method of securing the copper pipe to the vale is by a “wiped lead joint” so was brazing not available in 1848? On Tuesday 18 November (174 years to the day from when the valve was closed), I removed the ‘square’ under nut and collar but failed to turn the valve from closed to open position. The other end of the copper pipe was belled out for fitting to some other attachment.
The wreck is almost dry at low water spring tides with part of the engine visible, but covered by some 18 meters at high tide due to the Bristol Channels high rise and fall. This item was recovered by my son when diving among the scattered remaining items.
