  • Patent number: 6755445
    Abstract: A fitting for coupling a pump attachment to the inlet or discharge port of a pump or compressor has an annular body with an externally threaded nipple at one end and a circular flange at the other end. An axial aperture extends between the ends through openings at the nipple and the flange. The opening at the flange is internally threaded and begins at a recess in the flange. The threaded opening is of a standard ISO rated size complementary to the threaded nipple. A coupler kit is also disclosed having components to connect the device to the pump either in a mating flange connection using a hinge clamp or a threaded connection using a hose barb having a threaded end that threads into the opening in the fitting.

  • Patent number: 6708377
    Abstract: A clamp has two injection moulded tangs 1, 2 hinges together by a pin 3 and held closed by a wing nut 4 and a screw 5 having a cross-head 6. The tangs each have a tapered groove 7 running around inside them. In use, this groove engages flanges F on tubes T with a seal S therebetween to hold the tubes in sealing relationship with each other. The one tang 2 has a clevis 10 defined by two lugs 11. Each has an overhung recess 12 into which the cross-head 6 of the screw clips. A crossbar 14 connects the lugs remote from their tang, whereby the screw is limited in its angular displacement about the recesses 12, as shown in FIG. 3. The crossbar also stabilises the lugs against relative displacement under load when the nut is tightened. The other tang 1 has a part conical formation 21 on lugs 22 defining a clevis 23 similar to clevis 10. The nut has a complementary conical recess 24. Engagement of the formation 21 in the recess 24 restrains the lugs from separating under load as the nut is tightened.

  • Patent number: 6672631
    Abstract: A pipe coupling comprising two clamp halves connected on one end and with a rapid action closure for separably connecting the diametrically opposing other end. The rapid action closure contains a screw bolt, one end of which is coupled to one of the clamp halves and onto the other end of which a screw nut tightens the clamp half into the closed position. A lever lockable in the closed position by a bow-type spring is coupled to the screw nut. The pipe coupling comprises a bow-type spring in each clamp half, wherein the eyelet of the bow-type spring is centrally coupled to the region of the articulated connection between the clamp halves and the free end of the bow-type spring is held in the region of the end of each clamp half which is situated on the rapid action closure such that it can be longitudinally displaced.
