THE
"WILLIAMSON'
ENGINE
5/8in. Bore
1 3/8in. Stroke
Height 10in. (25.4 cm)
Approx. weight 6.5 Lb. (2.9 Kg)
This interesting and attractive model by "Tubal Cain" is a replica of a vertical engine made in the last century by the Kendal firm of Williamson Brothers. The original was about 8ft. 4in. (2.54m) high and ran at 130 r.p.m. with approximately 30 p.s.i. steam pressure, cylinder bore 6 1/2in., stroke 14in. It was exhibited in 1862 at the South Kensington International Machinery Exhibition and was no doubt intended for powering agricultural machinery. No actual example of the original is known to exist and this model has been scaled down (about 1:10) from catalogues and drawings.

The original design has been closely followed but a belt driven governor replaces the original's return crank and bevels and does not control engine speed.
This very pretty design is unique amongst the Stuart Turner stable. The main element is the cast hollow alluminium column. Futed and with frou oval openings to display the running gear inside. This is a 'real' engine with the crankshaft at the top and cylinder at the bottom. A square soleplate at the top is bordered by 3 decorative casting swith the original maufacturers name and town. A non functional version of the originals governer is mounted at the top and privides an interesting detail. With the name plate at the front the flywheel is mounted at the back. The crosshead runs in four slipper guides.
