Abstract
Abstract An improved arrangement for releasably connecting an end of a tubular gas filter bag to an aperture in an apertured plenum chamber plate member including a mounting member mounted in the aperture in the plate member for releasable engagement with the end of the bag. The mounting member includes an inwardly extending ledge located between an outwardly extending flange which engages the end of the bag and an inwardly extending seat which rests upon the periphery of the aperture. The ledge enables easy mounting of the bag end, which contains an expansible slip ring, over the flange.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
185 words
In a baghouse arrangement for filtering particulate matter from a gaseous stream including at least one plenum having an apertured member for gas passage therethrough and at least one vertically extending tubular filter bag with one of its ends connected to said apertured member in flow-through communication with said plenum, the improvement comprising: a flow-through elongated mounting member having a vertically extending portion with a radially outwardly extending flange at one end thereof in communication with said one end of said tubular filter bag, a radially inwardly extending seat at the opposed end thereof with a vertically downwardly extending portion terminating at its lower extremity, the vertically downwardly extending portion being received by the aperture in said apertured member such that the seat rests upon the periphery of the aperture, said vertically downwardly extending portion between said flange and said radially inwardly extending seat being defined by two vertically extending offset sections connected by a radially inwardly extending ledge portion; and, said one end of said tubular filter bag having a means releasably securing said tubular filter bag to said flange of said mounting member.
