Abstract
Abstract A thermocouple which may be attached to any type of support bracket, has a mounting portion and a pair of adaptors thereon in spaced relation to each other with each adaptor having a resilient element cooperating with the mounting portion to enable initial slip-on positioning of the two adaptors which may be finally moved into clamping positions relative to the support bracket.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
136 words
In combination, a universal thermocouple and a burner having a mounting bracket formed with aligned spaced-apart apertures, said thermocouple comprising: an elongated body of generally cylindrical configuration and including an externally threaded mounting portion that is received by the apertures of said bracket; an upwardly tapered frustro-conical flexible spring clip that is openable circumferentially and has its lower end locked in one of the apertures, said clip being flexibly engaged with said mounting portion; an adaptor having an internal bore that is coaxially received by said mounting portion; and friction means in said bore retained by sAid adaptor and defining a yieldable axially slidable operative connection between said adaptor and said mounting portion, with the outer surface of said adaptor being engageable with the other of said apertures to position said thermocouple relative to said burner.
Claim 2
Dependent Claim
136 words
In combination, a universal thermocouple and a burner having a mounting bracket formed with aligned spaced-apart apertures, said thermocouple comprising: an elongated body of generally cylindrical configuration and including an externally threaded mounting portion that is received by the apertures of said bracket; an upwardly tapered frustro-conical flexible spring clip that is openable circumferentially and has its lower end locked in one of the apertures, said clip being flexibly engaged with said mounting portion; an adaptor having an internal bore that is coaxially received by said mounting portion; and friction means in said bore retained by sAid adaptor and defining a yieldable axially slidable operative connection between said adaptor and said mounting portion, with the outer surface of said adaptor being engageable with the other of said apertures to position said thermocouple relative to said burner.
Claim 3
Dependent Claim
27 words
A thermocouple as set forth in claim 1 wherein said mounting portion is formed with external threads and said adaptor means is threadably adjustable on said threads.
Claim 4
Dependent Claim
17 words
A thermocouple as set forth in claim 1 wherein said friction means comprises a flexible detent element.
Claim 5
Dependent Claim
20 words
A thermocouple as set forth in claim 1 wherein said adaptor means is formed with steps of gradually reduced diameter.
Claim 6
Dependent Claim
25 words
A thermocouple as set forth in claim 4 wherein the sidewalls of said steps taper radially inwardly and toward one end of said adaptor means.
