Abstract
A universal filter mounting attachment for engine oil filters comprises a base having valved apertures therethrough and a threaded member selected for connection to a cooperating threaded member on a particular engine. The base carries a latch which cooperates with corresponding structure on the filter to latch the filter to the base and thus to the engine for circulation through the filter of oil from the engine. The base is normally left attached to the engine and the filter is unlatched therefrom for replacement or the like. The latch and the cooperating structure on the filter are designed such that filters may be manufactured in a single configuration and attached to all engines.

A universal filter mounting adaptor for internal combustion engines, comprises:
- a base plate having first seal means thereon for sealing engagement with an engine on which the adaptor is to be mounted and having first aperture means therethrough for flow of fluid from an engine and through the adaptor;
- a coupling member carried by the base plate for coupling engagement with complementary means on an internal combustion engine to secure the adaptor to the engine, said coupling member being selected for attachment to the particular engine on which it is used;
- a latch member carried by the base plate in a position for complementary latching engagement with latch means on a filter to be attached to the adaptor, said latch member being cooperable with all filters manufactured for use with the adaptor;
- second seal means on the base plate for sealing cooperation with a filter attached to the adaptor;
- normally closed valve means carried by the base plate to prevent loss of fluid from the engine through the first aperture means, said valve means being openable by fluid pressure developed in an engine to which the adaptor is attached;
- and said coupling member extending through the base plate and having means thereon for holding the base plate, latch and valve means assembled together for attachment as a unit to an engine.
In combination, an oil filter adaptor means having coupling means thereon for cooperation with conventional filter attaching structure on an engine to attach the adaptor means to the engine, latch means on the adaptor means for latching engagement with complementary latch means on a filter manufactured for use therewith, and a filter having complementary latch means thereon engaged with the latch means on the adaptor means, releasably latching the filter to the adaptor means and thereby releasably latching the filter to the engine, said adaptor means having first apertures therethrough for flow of oil from the engine through the adaptor means to the filter for filtration of the oil, first valve closure means biased toward closing relationship with the first apertures, said first valve closure means being moved toward open position by oil pressure developed in the engine, valve means in the filter, biasing means in the filter biasing the valve means toward closed position when the filter is removed from the adaptor means to prevent spillage of oil from the filter, and valve actuating means on the adaptor means engageable with the valve means in the filter to open the valve means when the filter is latched to the adaptor means to enable flow of oil through the filter.
