Abstract
Abstract An exhaust pipe ball connector has two iron rings with outer spherical surfaces. A sheet metal exit sleeve has a spherical end embracing one ring. A sheet metal downstream tube is beaded and flanged to engage the inside of that ring. A sheet metal upstream tube at one end telescopes into the downstream tube, with an annular seal between the telescoping portions, and at the other end is spherical and embraces the other ring. A sheet metal entrance sleeve is beaded and flanged to engage the inside of the other ring.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
205 words
An exhaust pipe ball connector comprising a first ring having a circular-cylindrical interior surface and a spherical outer surface, an entrance sleeve having one end disposed within said first ring against said interior surface, means on said entrance sleeve providing an out-turned flange abutting one edge of said first ring, means on said entrance sleeve providing an external bead abutting the other edge of said first ring, a second ring having a circular-cylindrical interior surface and a spherical outer surface, an exit sleeve, means on said exit sleeve forming a spherical inner surface disposed against said spherical outer surface on said second ring, a downstream tube having one end disposed within said second ring against said interior surface, means on said downstream tube providing an out-turned flange abutting one edge of said second ring, means on said downstream tube providing an external bead abutting the other edge of said second ring, an upstream tube, means on said upstream tube forming a spherical inner surface disposed against said spherical outer surface on said first ring, means on said upstream tube telescoping within said downstream tube, and a seal disposed in said external bead on said downstream tube and abutting the telescoping portion of said upstream tube.
Claim 2
Dependent Claim
205 words
An exhaust pipe ball connector comprising a first ring having a circular-cylindrical interior surface and a spherical outer surface, an entrance sleeve having one end disposed within said first ring against said interior surface, means on said entrance sleeve providing an out-turned flange abutting one edge of said first ring, means on said entrance sleeve providing an external bead abutting the other edge of said first ring, a second ring having a circular-cylindrical interior surface and a spherical outer surface, an exit sleeve, means on said exit sleeve forming a spherical inner surface disposed against said spherical outer surface on said second ring, a downstream tube having one end disposed within said second ring against said interior surface, means on said downstream tube providing an out-turned flange abutting one edge of said second ring, means on said downstream tube providing an external bead abutting the other edge of said second ring, an upstream tube, means on said upstream tube forming a spherical inner surface disposed against said spherical outer surface on said first ring, means on said upstream tube telescoping within said downstream tube, and a seal disposed in said external bead on said downstream tube and abutting the telescoping portion of said upstream tube.
Claim 3
Dependent Claim
18 words
A connector as in claim 1 in which said first and second rings are of heat-conducting, solid material.
Claim 4
Dependent Claim
31 words
A connector as in claim 1 in which said entrance sleeve, said exit sleeve, said upstream tube and said downstream tube are all of substantially the same thickness of sheet metal.
Claim 5
Dependent Claim
28 words
A connector as in claim 1 in which at least some of the telescoping portions of said upstream tube and said downstream tube lie within said second ring.
Claim 6
Dependent Claim
66 words
A connector as in claim 1 in which said spherical outer surface of said first ring and said spherical inner surface of said upstream tube slide over each other, said spherical outer surface of said second ring and said spherical inner surface of said exit sleeve slide over each other, and the telescoping portions of said upstream tube and said downstream tube slide over each other.
