On the return stroke or swing of thelever A, the pawls M and N engage theratchet wheel D and prevent it from ro-tating in a direction opposite to the arrowY. Thus the shaft G is given an inter-mittent rotary motion in one directionlike the hands of a clock. The whole caseis filled with grease, to reduce wear, whileleakage is prevented by the stuffing boxesQ and T. The rotary motion given to theshaft B is transmitted through a shaft anduniversal couplings to the lubricatorproper, which is placed on a bracket inthe cab. Referring to Fig. 4, suppose that thereservoir has been filled with oil throughthe screen W and that the machine has. FIG. SECTION OF LUBRICATOR. been in operation until the entire systemis filled with oil. The eccentric T is anintegral part of the shaft G, while thecrosshead Z is fastened rigidly to the ec-centric rod C. but may be adjusted onthe pump-plunger E. The crosshead O isfastened rigidly to both pump-plungers Eand F, so that whatever motion one has,both have. As the shaft G and the eccen-tric T are revolved, the eccentric rod Cis moved up and down, and imparts asimilar movement to the pump-plungersE and F. When the plunger F moves upward, oilis drawn from the reservoir through thescreen B and is lifted above the ballcheck S, while on the downward strokethe oil is forced past the ball check M,to the point I, from where it dripsthrough the sight feed V.
