In A the two valves a b are connected by a turning the handle e in oue direction the valve ais depressed by means of a ])in working on an in-clined plane, and admits oil to the resenoir. Areverse motion opens the valve 6, furnished with asimilar contrivance, permitting the oil to flow fromtlie reservoir. The valve a is kept to its seat by aspiral spring on the rod. B. Steam is admitted through the pipe a to theoil-chamber b, forcing out the lubricating materialthrough an opening to the desired iioint. The sup-ply of oil from the cup c is regulated liy a cock, anda cock d at the side of the oil-chamber permits accu-.
