Inventors: Pall, David B.;
Assignee: Pall Corporation (Glen Cove, NY)
Primary Examiner: Spitzer; Robert H.
Assistant Examiner:
Attorney, Agent or Firm:

An end cap coupler system for linking one end-capped filter cartridge to another at the end cap thereof or to another functional member is provided, comprising, in combination: (1) first and second attaching members, each having first and second opposed faces, (a) a first face of each attaching member facing one end of a filter cartridge or another functional member; and (b) a second face of each attaching member being adapted for closely-abutting contact with the second face of the other attaching member; (2) an outer periphery of the second face terminating in an outwardly extending flange, the flange of each member being adapted for closely-abutting contact when the second faces of each member are in closely-abutting contact; (3) at least two intermeshing clamping channel members having channel sides shaped to embrace the abutting flanges of the attaching members and spaced apart sufficiently to engage the flanges and clamp the attaching members together; each channel member having intermeshing locking means engaging mating locking means of the other member and releasably locking the channel members together in such clamping and embracing position; whereby each of the first and second attaching members when a part of or attached to one end cap of an end-capped filter cartridge releasably links the filter cartridge to an end cap of another end-capped filter cartridge or to another functional member.

DETAILED DESCRIPTION Having regard to the foregoing disclosure, the following is claimed as inventive and patentable embodiments thereof: 1.
A slide-on end cap coupler for linking an end-capped filter cartridge to another end-capped filter cartridge or to another functional member at the end cap thereof, comprising, in combination: (1) first and second attaching members, each having first and second opposed faces, (a) a first face of each attaching member facing one end of a filter cartridge or other functional member; and (b) a second face of each attaching member being adapted for closely-abutting contact with the second face of the other attaching member; (2) an outer periphery of the second face terminating in an outwardly extending flange, the flange of each member being adapted for closely-abutting contact when the second faces of each member are in closely-abutting contact; (3) at least two intermeshing clamping channel members having channel sides shaped to slidably move into and away from a clamping position in which the sides circumferentially embrace the abutting flanges of the attaching members and spaced apart sufficiently to engage the flanges and clamp the attaching members together; each channel member having intermeshing locking means engaging mating locking means of the other member and releasably locking the channel members together in such clamping and embracing position; and in such position embracing substantially the entire periphery of the flanges; whereby each of the first and second attaching members when a part of or attached to one end cap of an end-capped filter cartridge releasably and slidably links the filter cartridge to an end cap of another end-capped filter cartridge or to another functional member.
2.
An end cap coupler according to claim 1 in which the attaching members each have interconnecting apertures for fluid flow therethrough, and the functional member is a closure closing off the interconnected apertures at one end thereof.
3.
An end cap coupler according to claim 1 in which the attaching members each have interconnecting apertures for fluid flow therethrough and the functional member is a linking member for connecting the coupler to a filter assembly
