Total Claims: 4
Claim 1
Independent Claim
236 words
A filter and a mounting means therefor comprising: a filter for removing particles from gaseous fluid and having inlet and outlet faces, a rigid surrounding frame for said filter having a peripheral face portion, a nonrigid entrance duct member having an outer end and an inner end extending to said frame and being in overlapped relation to said peripheral face portion, a nonrigid exit duct member having an outer end and an inner end extending to said frame and being in overlapped relation to said peripheral face portion, said duct members being of flexible material and the outer end of each duct member being movable toward and away from its inner end, said inner ends of said duct members having a cross section at least as large as the inlet and outlet faces of the filter, sealing means interposed between said inner ends of said ducts and said peripheral face portion, fixed supporting members for supporting said frame in operating position independently of the outer ends of said duct members, and members for detachably connecting the outer ends of said duct members into a duct system whereby said duct members have their outer ends collapsibly movable with respect to said frame for installation in and removal from said duct system, one of said duct members having its inner end in overlapped relation to the inner enD of the other duct member on said peripheral face portion.
Claim 2
Dependent Claim

A filter and a mounting means therefor comprising: a filter for removing particles from gaseous fluid and having inlet and outlet faces, a rigid surrounding frame for said filter having a peripheral face portion, a nonrigid entrance duct member having an outer end and an inner end extending to said frame and being in overlapped relation to said peripheral face portion, a nonrigid exit duct member having an outer end and an inner end extending to said frame and being in overlapped relation to said peripheral face portion, said duct members being of flexible material and the outer end of each duct member being movable toward and away from its inner end, said inner ends of said duct members having a cross section at least as large as the inlet and outlet faces of the filter, sealing means interposed between said inner ends of said ducts and said peripheral face portion, fixed supporting members for supporting said frame in operating position independently of the outer ends of said duct members, and members for detachably connecting the outer ends of said duct members into a duct system whereby said duct members have their outer ends collapsibly movable with respect to said frame for installation in and removal from said duct system, one of said duct members having its inner end in overlapped relation to the inner enD of the other duct member on said peripheral face portion.
Claim 3
Dependent Claim
250 words
A filter and a mounting means therefor comprising: a filter for removing particles from gaseous fluid and having inlet and outlet faces, a rigid surrounding frame for said filter having a peripheral face portion, a nonrigid entrance duct member having an outer end and an inner end extending to said frame and being in overlapped relation to said peripheral face portion, a nonrigid exit duct member having an outer end and an inner end extending to said frame and being in overlapped relation to said peripheral face portion, said duct members being of flexible material and the outer end of each duct member being movable toward and away from its inner end, said inner ends of said duct members having a cross section at least as large as the inlet and outlet faces of the filter, sealing means interposed between said inner ends of said ducts and said peripheral face portion, fixed supporting members for supporting said frame in operating position independently of the outer ends of said duct members, detachable connecting members for detachably connecting the outer ends of said duct members into a duct system whereby said duct members have their outer ends collapsibly movable with respect to said frame for installation in and removal from said duct system, said fixed supporting members being in surrounding relation to said frame comprising channels with their web portions in flat relation to said peripheral face portion, and rails with which at least two of said channels are in slidable engagement.
