Hook Norton Brewery uses a Buxton & Thornley
steam engine that has powered most of the machinery in the brewery since 1899. It is the last commercially working open crank stationary steam engine in the UK. It is a small, simple engine consisting of a cylinder, flywheel, connecting rods and little else. The engine drives a system of shafts and belts connected to most of the machinery in the brewery; different sections of machinery can be engaged and disengaged by levers which slide drive belts on and off their wheels. Where there are gears in the lineshafting, each pair consists of one iron and one wooden wheel. Thus, if any machinery should jam, only a few wooden teeth will be damaged and can then be replaced by the brewery's mechanics instead of needing a complex iron casting. The machinery once powered by the steam engine includes: •
Pumps, both for "liquor" (water) and wort. The pumps are located next to the engine and are original. • The
grist mill, which crushes the grains of malt by a precisely-regulated amount. This is also an original 1899 machine. • The
mashing and
raking equipment in the mash tun. • A
lift for filled casks, dating from 1900. • The
sack hoist for loading malt. The steam engine now only powers the mashing equipment, mill and sack hoist on certain days. The mashing rakes and cask lift have been removed. ==Tied houses==
