Lubricating apparatus for pumping unit engines

Apparatus for continuously lubricating a pumping unit engine having exposed intake and exhaust valve means, rocker arm means and carburetor throttle mechanism positioned at one end thereof comprising:

• a housing including a top and bottom adapted to be attached to said engine over said intake and exhaust valve means and over said rocker arm means for preventing dust and other foreign matter from depositing thereon, said housing including at least one lubricant flow passageway disposed in the top thereof positioned over said intake and exhaust valve means and said rocker arm means of said engine when said housing is attached to said engine whereby lubricant flowing through said lubricant flow passageway flows by gravity onto said valve and rocker arm means thereby lubricating such means;
• an orifice for restricting the flow of lubricant flowing through said lubricant flow passageway attached to said housing over said passageway;
• a lubricant reservoir having a lubricant flow passageway disposed therein sealingly connected to said lubricant flow passageway in said housing whereby lubricant contained in said reservoir flows by gravity through said lubricant flow passageways in said reservoir and in said housing, through said orifice and onto said valve and rocker arms means of said engine;
• a second lubricant flow passageway disposed in the bottom of said housing for withdrawing excess lubricant therefrom by gravity;
• and
• a conduit sealingly attached to said second lubricant flow passageway for conducting lubricant withdrawn from said housing by gravity to said carburetor throttle mechanism whereby said mechanism is also lubricated.
