Abstract
Abstract A device for draining an engine sump of the type having a threaded drain plug comprises a cup-like container having a flexible flange surrounding the open end thereof. The flange is provided with a gasket for forming a fluid tight seal between the sump and the container and with magnet means for adhering the container to the sump. A shaft carrying a socket on one end extends into the container and is sealably movable with respect thereto. Once the container is placed in position over a drain plug, the plug can be engaged and removed by manually turning a handle provided on the other end of the shaft. After removal of the plug, oil from the sump drains from a tube at the bottom of the container whereby contact with the oil by the service person is completely avoided.

Claim 1
Independent Claim
209 words
A device for draining fluid from an engine sump of the type having a threaded drain plug comprising: a housing having an open end and a closed end; annular sealing means mounted to said housing for forming a fluid tight seal between the sump and the open end of said housing; a shaft extending into said housing through an opening in the closed end thereof; resilient sealing means forming a fluid tight seal between said shaft and said closed end of said housing while permitting axial and rotational movement of said shaft with respect to said closed end; socket means connected to the end of said shaft within said housing for non-rotatably engaging said plug for removal thereof from said sump upon rotational movement of said shaft; a flexible drain tube connected over an opening in said housing for draining said housing of fluid following removal of said plug from said sump, a yoke pivotably mounted to said housing for swinging movement about an axis extending in a direction transverse to the longitudinal axis of said shaft, tubular means carried by said yoke, said tubular means having an open end disposed in proximity to said yoke, and said drain tube extends into said open end of said tubular means.
