Abstract
Abstract A manifold coupling assembly for mounting one or more tubes in fluid communication with a mating coupling member is disclosed. The assembly includes a C-shaped channel section having a thin web section extending between spaced side rails which project from one face of the web section. One or more apertures are pierced or punched through the web section and a tube is mounted in each aperture by brazing or soldering the tube thereto. The tube is also brazed or soldered to adjacent portions of the side rails so that the tube is restrained from movement in planes normal to and aligned with the longitudinal axis of the channel section. According to one aspect of the invention, the C-shaped channel section is extruded so that the spaced side rails have diverging faces. Portions of the apertures are defined by and formed in the faces which more securely retain and mechanically lock the tubes. According to another aspect of this invention, the apertures are pierced or punched in a flat strip and the strip is then formed to its C-shaped cross section. These operations may be performed sequentially by progressive die techniques.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
72 words
A manifold coupling for mounting one or more tubes in fluid communication with a mating coupling member, comprising a Cshaped channel section having a thin web section extending between spaced side rails which project and diverge from one face of said web section, at least one circular aperture through said web with opposed faces of said side rails being substantially adjacent to said aperture, said aperture being partially formed in said faces.
Claim 2
Dependent Claim
72 words
A manifold coupling for mounting one or more tubes in fluid communication with a mating coupling member, comprising a Cshaped channel section having a thin web section extending between spaced side rails which project and diverge from one face of said web section, at least one circular aperture through said web with opposed faces of said side rails being substantially adjacent to said aperture, said aperture being partially formed in said faces.
Claim 3
Dependent Claim
26 words
A manifold coupling assembly according to claim 1, wherein at least two circular apertures are provided and a mounting aperture is provided in said web section.
Claim 4
Dependent Claim
19 words
A manifold coupling assembly according to claim 2, wherein said mounting aperture is non-equidistantly spaced from said circular apertures.
Claim 5
Dependent Claim
15 words
A manifold coupling according to claim 1, wherein said C-shaped channel section is an extrusion.
Claim 6
Dependent Claim
15 words
A manifold coupling according to claim 1, wherein said C-shaped channel section is a stamping.
Claim 7
Dependent Claim
107 words
A manifold coupling assembly mounting one or more tubes in fluid communication with a mating coupling member, comprising a C-shaped channel section having a thin web section extending between spaced side rails which project from one face of said web section, at least one circular aperture through said web with opposed faces of said side rails being substantially adjacent to said aperture, a tube mounted in each aperture, and means joining said tube to adjacent faces of said side rails to prevent movement in planes normal to and aligned with the longitudinal axis of said channel section and to prevent rotation of said tube about its axis.
Claim 8
Dependent Claim
107 words
A manifold coupling assembly mounting one or more tubes in fluid communication with a mating coupling member, comprising a C-shaped channel section having a thin web section extending between spaced side rails which project from one face of said web section, at least one circular aperture through said web with opposed faces of said side rails being substantially adjacent to said aperture, a tube mounted in each aperture, and means joining said tube to adjacent faces of said side rails to prevent movement in planes normal to and aligned with the longitudinal axis of said channel section and to prevent rotation of said tube about its axis.
