Abstract
Abstract An adjustable joint coupling assembly for joining a pipe having an annular corrugation thereabout to an end attachment, such as a gate for controlling the flow of fluid through said pipe, a second pipe in end-to-end relationship, or a cap to stop any fluid flow therethrough, said assembly comprising a plurality of clamping members each having an arm pivotal about one end thereof in a plane substantially parallel to the axis of said pipe, and means for securing said arm to said pipe and restricting its movement to within said plane. The opposite end of said arm is provided with means for engagement with said end attachment to securely hold same against said pipe, whereby to provide a substantially leak resistant joint.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
167 words
In combination with a pipe having at least one annular corrugation thereabout and an end attachment to be joined thereto, a joint coupling assembly adapted to provide a substantially uniform pressure between said pipe and said attachment and comprising a plurality of clamping members each having an arm pivotal about one end thereof in a plane substantially parallel to the axis of said pipe, means for securing said arm to said pipe and restricting its movement to within said plane, said means including a plurality of brackets adapted to seat in said corrugation, and an annular member seated in said brackets and capable of being constricted inwardly about said brackets, wherein said brackets are disposed between said pipe and said annular member, said brackets being held within said corrugation by said annular member and restricted to a sliding movement thereby in relation to said corrugation, and means at the opposite end of said arms foR engagement with and to securely hold said end attachment against said pipe.
Claim 2
Dependent Claim
167 words
In combination with a pipe having at least one annular corrugation thereabout and an end attachment to be joined thereto, a joint coupling assembly adapted to provide a substantially uniform pressure between said pipe and said attachment and comprising a plurality of clamping members each having an arm pivotal about one end thereof in a plane substantially parallel to the axis of said pipe, means for securing said arm to said pipe and restricting its movement to within said plane, said means including a plurality of brackets adapted to seat in said corrugation, and an annular member seated in said brackets and capable of being constricted inwardly about said brackets, wherein said brackets are disposed between said pipe and said annular member, said brackets being held within said corrugation by said annular member and restricted to a sliding movement thereby in relation to said corrugation, and means at the opposite end of said arms foR engagement with and to securely hold said end attachment against said pipe.
Claim 3
Dependent Claim
37 words
The combination of claim 1, wherein one side of each said bracket is attached to said annular member and the opposite side lies contiguous with at least a portion of the angled surface of the underlying corrugation.
Claim 4
Dependent Claim
24 words
The combination of claim 2, wherein said one side of each said bracket is provided with an upturned channel to receive said annular member.
Claim 5
Dependent Claim
34 words
The combination of claim 1, wherein said end attachment comprises a closure for said pipe, said closure being provided with an annular flange to be engaged by said opposite ends of the pivotal arms.
Claim 6
Dependent Claim
32 words
The combination of claim 4, wherein each said pivotal arm is substantially L-shaped, and that said engagement is achieved by inserting one leg of each said arm into openings in said flange.
Claim 7
Dependent Claim
28 words
The combination of claim 1, wherein each said arm is a member threaded on at least one end thereof and adapted to be secured to said end attachment.
Claim 8
Dependent Claim
20 words
The combination of claim 6, wherein each said threaded member is provided with an integral head at one end thereof.
Claim 9
Dependent Claim
23 words
The combination of claim 1, including means to predetermine the distance from said opposite end of each said arm to its corresponding bracket.
Claim 10
Dependent Claim
170 words
In combination with two pipes having similar diameters and placed in end-to-end relationship, wherein each said pipe is provided with at least one annular corrugation near said ends, a coupling assembly adapted to provide a substantially uniform pressure between said pipes and comprising a plurality of clamping members uniformly spaced about the outside of said pipes, each said clamping member being secured to said pipes by a pair of opposed annular members, said clamping member comprising a pair of brackets, where one bracket of each said pair is adapted to seat in a corrugation in a different one of said pipes, and each said annular member is seated in one bracket of each said pair thereof, wherein said brackets are disposed between one of said pipes and its corresponding annular member and held within said corrugation by its annular member and restricted to a sliding movement thereby in relation to said corrugation, and an elongated member engaging each said pair of brackets whereby to secure said pipes in end-to-end relationship.
Claim 11
Dependent Claim
170 words
In combination with two pipes having similar diameters and placed in end-to-end relationship, wherein each said pipe is provided with at least one annular corrugation near said ends, a coupling assembly adapted to provide a substantially uniform pressure between said pipes and comprising a plurality of clamping members uniformly spaced about the outside of said pipes, each said clamping member being secured to said pipes by a pair of opposed annular members, said clamping member comprising a pair of brackets, where one bracket of each said pair is adapted to seat in a corrugation in a different one of said pipes, and each said annular member is seated in one bracket of each said pair thereof, wherein said brackets are disposed between one of said pipes and its corresponding annular member and held within said corrugation by its annular member and restricted to a sliding movement thereby in relation to said corrugation, and an elongated member engaging each said pair of brackets whereby to secure said pipes in end-to-end relationship.
Claim 12
Dependent Claim
37 words
The combination of claim 9, wherein one side of each said bracket is attached to its annular member and the opposite side lies contiguous with at least a portion of the angled surface of the underlying corrugation.
Claim 13
Dependent Claim
24 words
The combination of claim 10, wherein said one side of each said bracket is provided with an upturned channel to receive its annular member.
Claim 14
Dependent Claim
22 words
The combination of claim 9, wherein each said elongated member is a threaded rod having at least one member threadably engaged therewith.
Claim 15
Dependent Claim
19 words
The combination of claim 12, including means on said rod to predetermine the distance between said pair of brackets.
