Abstract: 
This invention relates to those up feed-lubricators, which are used on duplicate engine- cylinders or the twin cylinders of a locomotive, are attached to steam-boilers or live- steam pipes, and have a pair of oil-discharge pipes that deliver oil into the steam-cylinders and the principal feature of my present improvements comprises a novel combination of parts that prevents cross-feeding of oil from one cylinder of the engine to the other, and also removes all danger of siphonage when the locomotive runs on a downgrade with steam shut off from either one or both of the cylinders.
