  • Patent number: 5291969
    Abstract: An adapter mechanism for use between an engine and an oil cooler manifold, includes a special nut having internal threads for screw-on engagement with an externally threaded engine boss. External threads on the nut mate with threads on a central wall portion of an associated oil cooler manifold to operatively connect the manifold with oil passages in the engine block. Differently dimensioned nuts may be selectively utilized to connect a given manifold with a range of different engines. An annular adapter plate is positioned between the manifold and engine to provide sealed passage connections to or from the manifold passages.

  • Patent number: 4617702
    Abstract: An elongated, semi-rigid tie mount is disclosed, composed of polymer material and having a central, rectangular, U-shaped cross-sectional portion. A square or circular disk-shaped head is integrally formed at one end of the tie mount. A thin, rectangular tip portion, or tongue, is integrally formed at the other end of the tie mount. The trough, or bottom, of the central, rectangular, U-shaped portion is provided with a longitudinally extending array of serrated teeth projecting partially upward from the bottom of the trough. A slidable, apertured disk retainer, having a set of downwardly projecting, mating teeth, is disclosed for passage over the tip portion of the tie mount in a direction toward the head of the tie mount. An abrupt step is situated at the junction of the tip portion and the U-shaped cross-sectional portion to provide a stop. The stop serves to prevent the slidable, apertured disk portion from being incorrectly advanced onto the U-shaped cross-sectional portion.

  • Patent number: 4335688
    Abstract: A coupling adapter is disclosed for coupling a remotely-located fluid circulation device and a fluid filter to the fluid reservoir of an engine, transmission unit or other hydraulic system in place of a standard spin-on fluid filter. The adapter consists of a disk-shaped body having first and second spaced-apart end surfaces. First and second cylindrically-shaped cavities extend partially into the disk-shaped body, respectively, from the first and second end surfaces. A plurality of concentric ridges intersticed with concentric grooves is provided in the first end surface surrounding the first cylindrically-shaped cavity. A central wall section within the disk-shaped body separates the first and second cavities. A central bore extends coaxially through the central wall section for receiving and supporting a hollow nipple adapted to align and secure the coupling adapter to the fluid reservoir.

  • Patent number: 4278275
    Abstract: A universal coupling adapter is disclosed for attachment to the fluid reservoir of an engine, transmission unit, or other hydraulic system in place of a standard spin-on fluid filter. The coupling adapter consists of a disk-shaped body having a first end surface provided with a plurality of concentric ridges intersticed with concentric grooves. A centrally-located threaded bore extends into the disk-shaped body from the first end surface. A cylindrically-shaped cavity located between the innermost concentric ridge and the centrally-threaded bore extends partially into the disk-shaped body from the first end surface. An inlet port, with passageway interconnected with the centrally-located bore, and an outlet port, with passageway interconnected with the cylindrically-shaped cavity, extend from the second end surface of the disk-shaped body.
