Abstract
Abstract A split flange retainer assembly adapted to engage the flanged head to a conduit for mounting the conduit to a bulkhead, for example for hydraulic applications, is described. A pair of the split flange retainers are adapted to interconnect about the flanged head of the conduit to simulate the operation of a solid flange while retaining the advantages of split flanges.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
223 words
A split flange retainer segment adapted to cooperatively engage the flanged head of a conduit for mounting the same, comprising: a body portion of a given thickness and having an inner surface defined by adjacent upper and lower surfaces interconnected by a stepped shoulder, the shoulder adapted to engage said flanged head of the conduit for mounting; a first leg, of lesser thickness than the body portion and attached to and extending away from one end of the body portion, having an inner surface extending from a portion of the inner surface of the body portion; a second leg, of lesser thickness than the body portion and attached to and extending away from the other end of the body portion, having an inner surface extending from a portion of the inner surface of the body portion; a plurality of openings in the split flange retainer segment for engaging fastener means facilitating mounting the flanged head of the conduit; at least one of said openings including a through bore and a semi-bore axially interconnected and formed at the juncture between the body portion and at least one of said legs; and at least one of said first and second legs extending substantially beyond the body portion from one of the openings and terminating, at its tip, at a juncture with another of the openings.
Claim 2
Dependent Claim
223 words
A split flange retainer segment adapted to cooperatively engage the flanged head of a conduit for mounting the same, comprising: a body portion of a given thickness and having an inner surface defined by adjacent upper and lower surfaces interconnected by a stepped shoulder, the shoulder adapted to engage said flanged head of the conduit for mounting; a first leg, of lesser thickness than the body portion and attached to and extending away from one end of the body portion, having an inner surface extending from a portion of the inner surface of the body portion; a second leg, of lesser thickness than the body portion and attached to and extending away from the other end of the body portion, having an inner surface extending from a portion of the inner surface of the body portion; a plurality of openings in the split flange retainer segment for engaging fastener means facilitating mounting the flanged head of the conduit; at least one of said openings including a through bore and a semi-bore axially interconnected and formed at the juncture between the body portion and at least one of said legs; and at least one of said first and second legs extending substantially beyond the body portion from one of the openings and terminating, at its tip, at a juncture with another of the openings.
Claim 3
Dependent Claim
25 words
The split flange retainer of claim 1 wherein the inner surface of the body portion is curvilinear and the upper and lower surfaces are arcuate.
Claim 4
Dependent Claim
38 words
The split flange retainer of claim 1 wherein said first leg extends from one of said upper or lower surfaces of the body portion and said second leg extends from the other of said upper or lower surfaces.
Claim 5
Dependent Claim
27 words
The split flange retainer of claim 1 wherein said first and second legs both extend from one of said upper or lower surfaces of the body portion.
Claim 6
Dependent Claim
205 words
A split flange retainer assembly for making a fluid tight sealed connection to a bulkhead or the like, comprising: a conduit of a given diameter and having a flanged head and seal means interposed between the head and bulkhead for enabling the sealed connection; a pair of interconnecting flange segments having mating overlapping portions, said flange segments having inner arcuate surfaces with stepped shoulders and having an arc length greater than 180° and extending about the periphery of the conduit and the shoulder of the flange segments bearing against the flanged head of the conduit; said inner arcuate surface of each of the flange segments terminating in respective first and second arc tips, the distance between the first and second arc tips being less than the diameter of the conduit; each of said flange segments including four openings, two of the openings being full bores penetrating the flange segments and the other two openings being semi-bores positioned at each of said first and second arc tips; means for fastening through the openings the interconnected segment to the bulkhead and forming the sealed connection; and said interconnecting flanged segments, in assembly with the conduit, being interlocked so that the flange segments cannot be pulled radially apart.
Claim 7
Dependent Claim
205 words
A split flange retainer assembly for making a fluid tight sealed connection to a bulkhead or the like, comprising: a conduit of a given diameter and having a flanged head and seal means interposed between the head and bulkhead for enabling the sealed connection; a pair of interconnecting flange segments having mating overlapping portions, said flange segments having inner arcuate surfaces with stepped shoulders and having an arc length greater than 180° and extending about the periphery of the conduit and the shoulder of the flange segments bearing against the flanged head of the conduit; said inner arcuate surface of each of the flange segments terminating in respective first and second arc tips, the distance between the first and second arc tips being less than the diameter of the conduit; each of said flange segments including four openings, two of the openings being full bores penetrating the flange segments and the other two openings being semi-bores positioned at each of said first and second arc tips; means for fastening through the openings the interconnected segment to the bulkhead and forming the sealed connection; and said interconnecting flanged segments, in assembly with the conduit, being interlocked so that the flange segments cannot be pulled radially apart.
Claim 8
Dependent Claim
52 words
The assembly of claim 5 wherein the mating flange segments are defined by a body portion and two legs of lesser thickness than the body portion and extending from opposite ends of the body portion, the legs of one flange segment mating and overlapping with the legs of the other flange segment.
Claim 9
Dependent Claim
43 words
The assembly of claim 6 wherein said fastening means is comprised of four bolts penetrating cooperating holes in the flange segments, adapted and arranged such that each assembled bolt applies a force either directly or indirectly against each of the two flange segments.
Claim 10
Dependent Claim
208 words
A split flange retainer half for use in engaging the flanged head of a conduit having a given diameter, for coupling the same, comprising: a body portion of a given thickness and having an inner curvilinear surface defined by adjacent upper and lower circular arcuate surfaces joined by a stepped shoulder, the shoulder adapted to engage the flanged head of the conduit; first and second legs, of lesser thickness than the body portion and attached to and extending away respectively from each end of the body portion, each leg having an inner circular arcuate surface smoothly and continuously extending from at least one of said upper and lower arcuate surfaces of the body portion along the same circular arc defining said upper and lower arcuate surfaces; said body portion together with the marginally extending first and second legs together having a curvilinear inner circular arcuate surface characterized by an arc length greater than 180°; a plurality of openings in the split flange retainer half for receiving fastener means for coupling the flanged head of the conduit; and at least one of said openings including a through bore and a semi-bore axially interconnected and formed at the juncture between the body portion and at least one of said legs.
