Editing Automatic lubricator (section)

==Wick feed lubricator== 
Known also as ''syphon lubrication'', {{anchor|syphonic lubricator}}equipment using this method consists of reservoirs of oil with delivery pipes from the reservoir to the bearings, axleboxes, slide bars or [[Glossary of rail transport terms#Horn block|horn blocks]], mounted so that the open top ends of the pipes are above the maximum oil level. Assemblies called ''trimmings''—bundles of [[worsted]] yarn tied around  narrow wire frames—are tucked into the open ends of the delivery pipes so that a "tail" of threads drapes into the oil. [[Capillary action]]  draws the oil over the lip of the pipe for delivery by gravity. Variation in delivery rates comes from adjusting the size and tightness of the worsted bundles. The bundles of wool are effective in filtering out harmful contamination but do not work properly should water enter the reservoir.<ref name=RFH/><ref>{{cite web |title=Worsted Wool Instructions - Worsted Wool - Lubricators & Accessories |url=https://www.heritagesteamsupplies.co.uk/lubricators-accessories/worsted-wool/worsted-wool-instructions.html |website=www.heritagesteamsupplies.co.uk |publisher=Heritage Steam Supplies |access-date=14 October 2021}}</ref><ref>{{cite book |last1=Niño |first1=Emanuel |title=Industrial Lubrication |date=1997 |publisher=Rex |location=Manila, Philippines |isbn=9789712321788 |page=2}}</ref>
