In 1951 the Steel Company of Wales considerably extended their steelworks
and constructed an extra ninety coke ovens at Margam near Port Talbot. This
was the reason behind the publication by the Iron and Coal Trades Review of
a special issue of a 'Technical Survey of the Steel Company of Wales
Steelmaking' in 1952. Within this useful book, an advert was produced for
James Buchanan & Son. Because of the rarity of an imaginative Buchanan
advertisement (most of the others few in number were of a very simple
and basic design) the item is reproduced here. Two very different rams are
illustrated with the translated maxim 'experience teaches'. Pictured in the
upper part of the advert was a machine constructed for a Scottish plant in
1897, with a weight of five tons and it was stated that it 'gave over forty
years service'. An enlarged copy of this picture, possibly taken during the
war years, is shown at the head of this article and it is similar in many
respects to the general arrangement drawing reproduced overleaf. Again a cab
has been added, which is smaller than that of the stamper machine and an
operative (possibly female) can be seen at the driving position. Gearing,
boiler, cylinders and ram head can all be viewed. The safety valve is
situated in front of the cab; with the boiler feed apparatus below, on the
outside of the firebox.
Fortunately, at this early date, there was only one by-product coking plant
in Scotland and that was the Dumbreck/Twechar works of William Baird & Co.
Ltd in Stirlingshire who used fifty Semet-Solvay waste heat ovens to produce
blast furnace coke. These were later increased to 150 with a throughput of
230,000 tons pa to be eventually shut down in 1941. Undoubtedly this was
the location of the picture of this remarkable machine.
The view was used a second time in a different advert for the Buchanan ram
installed at the John Summers works at Shotton in Flintshire in the
following year.
By 1910 electricity was being used in many coking plants as the motive power
for the large equipment. This was so much more efficient and the electric
motors so powerful for their size, that steam in most cases was very swiftly
superseded as the power source. Certainly no new steam powered rams were
constructed for use in the U.K. after 1910 and the Dumbreck machine seems to
have been very much a late (and only) survivor of this interesting device.

The coaster Hartel grounded on Goole Ness in January 1951. Its Dutch owners
brought a salvage team across the North Sea and this was a significant event
in Claude's history because, after repairing some of the team's equipment,
he was impressed by the abilities of the man in charge and learned about the
techniques of salvaging and diving which stood him in good stead for the
future. The recovered vessel is shown in the Ouse being escorted towards
Goole docks by the tug Goole No 4 and the Dutch salvage vessel Luiken after
being raised in the following July, six months after the original accident.
