Abstract
Abstract A hanger assembly for pipe joints which includes a pipe joint coupling and a removable stabilizer for connecting the coupling to the hanger bar. The stabilizer includes a saddle sandwiched between the shield and the clamping bands of the coupling. The shield, in turn, surrounds the resilient sleeve into which the ends of the pipes project. The saddle is formed from a pair of thin arcuate saddle plates, the outer edges of which are provided with outwardly projecting alignment tabs. An outwardly projecting flat lug on the saddle is formed from a pair of flat rectangular opposed lug elements joined at their distal ends along a common edge and respectively joined to the saddle plates at their proximal ends. The lug has a hole for receiving a securing bolt which passes both through the lug and through an eyelet, at one end of the hanger rod. The other end of the hanger rod is anchored to the supporting structure. In one embodiment, the lug is disposed axially while, in the other embodiment, the lug is disposed radially. Each stabilizer depicted in the drawing is formed from a unitary piece of sheet metal. In a third embodiment, the axially disposed lug elements diverge from each other so as to pivot the saddle plates to conform to varying sizes of pipes.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
98 words
A hanger assembly comprising, in combination, a coupling for joining two end portions of pipes together and a stabilizer secured to said coupling, said stabilizer including a lug projecting away from said coupling by means of which the coupling and pipes can be supported from a supporting structure and a saddle carrying said lug, and a band for circumscribing a portion of the coupling, said band passing over a portion of said saddle, said saddle conforming to the contour of said coupling and being sufficiently thin that it does not materially alter the contour of the circumscribing band.
Claim 2
Dependent Claim
98 words
A hanger assembly comprising, in combination, a coupling for joining two end portions of pipes together and a stabilizer secured to said coupling, said stabilizer including a lug projecting away from said coupling by means of which the coupling and pipes can be supported from a supporting structure and a saddle carrying said lug, and a band for circumscribing a portion of the coupling, said band passing over a portion of said saddle, said saddle conforming to the contour of said coupling and being sufficiently thin that it does not materially alter the contour of the circumscribing band.
Claim 3
Dependent Claim
56 words
The hanger assembly defined in claim 1 wherein said stabilizer includes a saddle, said lug projecting outwardly from the central portion of said saddle, and wherein said coupling includes an additional band, the pair of bands passing on opposite sides of said lug and for passing around the junction of said end portions of said pipes.
Claim 4
Dependent Claim
130 words
The hanger assembly defined in claim 1 wherein said coupling includes a shield for extending around said end portions of said pipes and a pair of compression bands outwardly of and for extending around said shield for compressing said shield toward said end portions of said pipe when said shield extends around said end portions of said pipe, and wherein said stabilizer includes a saddle for carrying said lug, said saddle projecting in opposite directions from said lug and being curved to be generally concentric with said shield and said bands when they are installed around said end portions of said pipe, said saddle being sufficiently wide that said bands will simultaneously pass over said saddle and on opposite sides of said lug for securing said saddle against said shield.
Claim 5
Dependent Claim
34 words
The hanger assembly defined in claim 3 wherein said lug is generally flat and is disposed radially with respect to said coupling, when said coupling is installed on said end portions of said pipes.
Claim 6
Dependent Claim
34 words
The hanger assembly defined in claim 3 wherein said lug is generally flat and is disposed axially with respect to said coupling, when said coupling is installed on said end portions of said pipes.
Claim 7
Dependent Claim
37 words
The hanger assembly defined in claim 3 including tabs projecting outwardly from the edges of said saddle, said tabs confining said bands therebetween, when the coupling and saddle are installed on the end portions of said pipes.
Claim 8
Dependent Claim
55 words
The hanger assembly defined in claim 4 wherein said lug includes a pair of flat lug elements joined along a common edge and diverging from each other as they extend away from said common edge, said saddle including a pair of saddle plates extending in opposite directions respectively from the edges of said lug elements.
Claim 9
Dependent Claim
32 words
The hanger assembly defined in claim 1 wherein said lug is generally flat and provided with a hole through which a bolt can project for securing said lug to said supporting structure.
Claim 10
Dependent Claim
94 words
A hanger assembly comprising in combination: a. a coupling for joining two abutting end portions of pipes together, said coupling including a shield for extending around said end portions of said pipes and a pair of radially spaced compression bands circumscribing said shield for compressing said shield toward said end portions of said pipe; b. a stabilizer for securing said coupling to a supporting structure, said stabilizer including a saddle removably disposed between said shield and said bands and a lug carried by said saddle and protruding outwardly of said coupling and said saddle.
Claim 11
Dependent Claim
94 words
A hanger assembly comprising in combination: a. a coupling for joining two abutting end portions of pipes together, said coupling including a shield for extending around said end portions of said pipes and a pair of radially spaced compression bands circumscribing said shield for compressing said shield toward said end portions of said pipe; b. a stabilizer for securing said coupling to a supporting structure, said stabilizer including a saddle removably disposed between said shield and said bands and a lug carried by said saddle and protruding outwardly of said coupling and said saddle.
Claim 12
Dependent Claim
100 words
The assembly defined in claim 9 wherein said lug and said saddle are formed from a unitary sheet metal blank, said blank having spaced opposed saddle plates and a lug plate between and integrally joining said saddle plates along common edges, said lug plate being reversely bent intermediate its ends to define a pair of opposed abutting lug elements joined at their distal ends by another common edge, said blank being bent at the common edges of each of said saddle plates and said lug for disposing said saddle plates in oppositely extending relationship; respectively extending from said lug elements.
Claim 13
Dependent Claim
34 words
The assembly defined in claim 10 wherein one of said saddle plates is received under one of said bands and the other of said saddle plates is received under the other of said bands.
Claim 14
Dependent Claim
73 words
The assembly defined in claim 10 wherein said saddle plates are wider than said lug plates for providing end portions of said saddle plates which protruded beyond said lug plates, said end portions of said saddle plates at one end of said lug plates extending beneath one of said bands and said end portions of said saddle plates at the other end of said lug plates extending beneath the other of said bands.
