The "Sanspareil" was a four wheeled coupled engine and
with water in the boiler weighed 4 tons 15½ cwt. thus exceeding
by 5½ cwt, the weight allowed by the terms of the competition,
to be placed upon four wheels. The tender when charged with coke
and water weighed 3 tons, 6 cwt, 3 grs. The boiler was
cylindrical, 4'2" dia. and 6 ft. long and was twice
traversed, longitudinally by a return flue, one length of which,
enclosing the fire grate was 24" dia., while the other,
terminating in the chimney, was 15". Both flues were
prolonged 3 ft. beyond one end of the boiler a suitable water
space being made around this part of the flues. The chimney was
15" dia. the fire grate was 5 ft. long, thus presenting 10
sqr. ft. of area; that part of the flue answering to an ordinary
firebox was 15.7 sq. ft. in extent; while the remaining part of
the flue measured 74.6 sq. ft.
The cylinders were vertical and were 7" dia. by 18"
stroke. The connecting rods worked upon crank pins, in one pair
of wheels with which the others were coupled by rods, all the
wheels being 4 ft. 6 in. in diameter. The exhaust stream from
teh cylinders was sent through pipes into a single contracted
nozzle or blast pipe turned upward in the centre of the chimney. |
