Abstract
Abstract A method of forming a slidable interconnection between a tube and an opening in a plate. In accordance with one form of the disclosure said tube is inserted through an opening in said plate and a pair of annular projections are formed on said tube. Prior to forming said projections, a first washer is placed on the tube on one side of said plate and a second washer and a collar formed from an easily destructible material are placed on the tube on the opposite side of the plate with said collar carried against one face of said plate. Said projections are brought into binding engagement with said washers. After said projections are disposed in such binding engagement, the collar is removed to reduce the tightness of the fit between said washers and the plate.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
146 words
A method of interconnecting a tube to a plate, comprising the steps of supporting a first washer against one face of a plate, placing an annular collar formed of an easily destructible material against the opposite face of said plate, placing a second washer on said collar, said collar, washers and plate having openings whose axes are disposed in alignment with each other and whose cross-sections are substantially larger than the diameter of said tube, inserting said tube through said opening, forming a first annular projection on said tube in engagement with said first washer, forming a second annular projection on said tube in engagement with said second washer, forcing said projections into binding engagement with said washers, and removing said collar to permit said tube and plate to move with respect to each other at said plate opening radially with respect to the tube axis.
Claim 2
Independent Claim
146 words
A method of interconnecting a tube to a plate, comprising the steps of supporting a first washer against one face of a plate, placing an annular collar formed of an easily destructible material against the opposite face of said plate, placing a second washer on said collar, said collar, washers and plate having openings whose axes are disposed in alignment with each other and whose cross-sections are substantially larger than the diameter of said tube, inserting said tube through said opening, forming a first annular projection on said tube in engagement with said first washer, forming a second annular projection on said tube in engagement with said second washer, forcing said projections into binding engagement with said washers, and removing said collar to permit said tube and plate to move with respect to each other at said plate opening radially with respect to the tube axis.
Claim 3
Independent Claim
130 words
A method of interconnecting a tube to a plate, comprising the steps of inserting a tube through aligned openings in a stack consisting successively of a first washer, an annular collar, a plate, and a second washer, said collar being formed of an easily destructible material, forming a first annular projection in a first position around said tube in engagement with said first washer, forming a second annular projection in a second position around said tube in engagement with said second washer, said first and second positions being axially disposed along said tube to cause said projections to bindingly engage said washers, and removing said collar to permit said tube and plate to move with respect to each other at said plate opening radially with respect to the tube axis.
Claim 4
Independent Claim
130 words
A method of interconnecting a tube to a plate, comprising the steps of inserting a tube through aligned openings in a stack consisting successively of a first washer, an annular collar, a plate, and a second washer, said collar being formed of an easily destructible material, forming a first annular projection in a first position around said tube in engagement with said first washer, forming a second annular projection in a second position around said tube in engagement with said second washer, said first and second positions being axially disposed along said tube to cause said projections to bindingly engage said washers, and removing said collar to permit said tube and plate to move with respect to each other at said plate opening radially with respect to the tube axis.
Claim 5
Dependent Claim
39 words
The method of interconnecting a tube to a plate as set forth in claim 2 in which said steps of forming annular projections on said tube comprise deforming said tube to form integral projections thereon extending radially outwardly therefrom.
Claim 6
Dependent Claim
36 words
The method of interconnecting a tube to a plate as set forth in claim 2 in which said steps of forming annular projections on said tube comprise fixedly mounting a pair of rings on said tube.
Claim 7
Dependent Claim
36 words
The method of interconnecting a tube to a plate as set forth in claim 2 in which said collar is combustible and said step of removing said collar comprises burning said collar off of said tube.
Claim 8
Independent Claim
132 words
A method of interconnecting a tube to a plate, comprising the steps of inserting a tube through aligned openings in a plate and an annular collar, said plate opening being substantially larger than the diameter of said tube and said collar being formed from an easily destructible material, forming a first annular projection in a first position around said tube in engagement with said collar, forming a second annular projection in a second position around said tube in engagement with said plate, said first and second positions being axially disposed along said tube to cAuse said projections to bindingly engage said collar and plate, and removing said collar to permit said tube and plate to move with respect to each other at said plate opening radially with respect to the tube axis.
Claim 9
Independent Claim
132 words
A method of interconnecting a tube to a plate, comprising the steps of inserting a tube through aligned openings in a plate and an annular collar, said plate opening being substantially larger than the diameter of said tube and said collar being formed from an easily destructible material, forming a first annular projection in a first position around said tube in engagement with said collar, forming a second annular projection in a second position around said tube in engagement with said plate, said first and second positions being axially disposed along said tube to cAuse said projections to bindingly engage said collar and plate, and removing said collar to permit said tube and plate to move with respect to each other at said plate opening radially with respect to the tube axis.
