Abstract: An air chuck fitting to be attached to a flexible pressurized air hose for providing a manual press-fitted connection to the valve stem of an automobile tire or the like, and consisting of a tubular body member attachable to the hose end and having a pressure-seated plunger valve therein, the plunger valve having a plunger extension which, when pressed over the valve stem of an automobile tire, opens both the plunger valve and the air valve of the stem to admit air to the stem, the invention being characterized by the construction of the body member, hose and plunger valve assembly, wherein a single assembly member performs the functions of providing a sealed connection of the hose to the body member, limiting and controlling the motion of the plunger valve, and providing for air passage from the hose to the plunger valve.

Abstract: A crankcase oil drainage and collection device consisting of a threaded drainage plug especially designed to present an enlarged head at its outer end normally having sealing contact with the crankcase, but not to initiate any appreciable drainage of oil until the enlarged head has been retracted to a substantial distance from the crankcase, and a container for oil having a special neck engageable over the plug head when said plug is partially retracted, the neck having a funnel extension engageable with the crankcase to direct oil from the crankcase to the container, the plug being operable to effectively open the crankcase drain opening when it is screwed still further from the crankcase, but before it is disengaged from the crankcase.
