Abstract
Abstract An end of a bellows having radially spaced inner and outer plies is mounted to a support having a wall and further having a tubular flange extended from the wall and inserted between the plies. Cylindrical weldments, preferably butt weldments, are deposited on the flange to weld the inner and outer plies to the support.

Claim 1
Independent Claim
65 words
A combination comprising a bellows including radially spaced inner and outer plies, a support for one end of said bellows, said support including a wall, a tubular flange extending from said wall in normal relation to said wall, said flange being inserted between said inner and outer plies, and cylindrical weldments deposited on said flange to weld said inner and outer plies to said support.
Claim 2
Dependent Claim
65 words
A combination comprising a bellows including radially spaced inner and outer plies, a support for one end of said bellows, said support including a wall, a tubular flange extending from said wall in normal relation to said wall, said flange being inserted between said inner and outer plies, and cylindrical weldments deposited on said flange to weld said inner and outer plies to said support.
Claim 3
Dependent Claim
32 words
The combination of claim 1 wherein said weldments comprise a cylindrical butt weldment deposited on a radially outer surface of said flange between an edge of said outer ply and said wall.
Claim 4
Dependent Claim
32 words
The combination of claim 1 wherein said weldments comprise a cylindrical butt weldment deposited on a radially inner surface of said flange between an edge of said inner ply and said wall.
Claim 5
Dependent Claim
56 words
The combination of claim 1 wherein said weldments comprise a cylindrical butt weldment deposited on a radially outer surface of said flange between an edge of said outer ply and said wall and a cylindrical butt weldment deposited on a radially inner surface of said flange between an edge of said inner ply and said wall.

The combination of claim 1 wherein a passage extending axially through said tubular flange communicates with a space between said plies.
Claim 7
Dependent Claim
21 words
The combination of claim 5 further comprising tubular means mounted to said support and connected to said space through said passage.
Claim 8
Dependent Claim
64 words
A combination comprising a bellows including radially spaced inner and outer plies, a support for one end of said plies, said plies being welded to said support by circumferential weldments radially spaced on said support, said support including a passage which extends through said support but not through either ply and which opens between said weldments to communicate with a space between said plies.
Claim 9
Dependent Claim
64 words
A combination comprising a bellows including radially spaced inner and outer plies, a support for one end of said plies, said plies being welded to said support by circumferential weldments radially spaced on said support, said support including a passage which extends through said support but not through either ply and which opens between said weldments to communicate with a space between said plies.
