Some [[steam locomotive]]s were fitted with one or more Wakefield mechanical [[lubricator]]s. These were normally mounted on the locomotive footplate alongside the boiler, in a position where a mechanical linkage could be made with some point on the locomotive's valve gear or another moving part. The reciprocation of this caused a lever on the lubricator to oscillate, and this was converted to a small rotary movement by a [[Ratchet (device)|ratchet]]. The gradual rotation caused a small amount of lubricating oil to be fed into pipes leading to the cylinders, valves and other parts. The amount of oil fed was in proportion to the distance travelled by the locomotive in either direction.<ref>{{cite book |last1=Semmens |first1=P.W.B. |last2=Goldfinch |first2=A.J. |title=How Steam Locomotives Really Work |year=2003 |orig-year=2000 |publisher=[[Oxford University Press]] |location=Oxford |isbn=0-19-860782-2 |pages=201–4 }}</ref>
