Claims
- 1. A heater for a track rail, comprising:
- a heater element assembly comprising an elongate metal housing for mounting on said rail, said elongate housing including substantially flat, conductive heat transfer surface means for conductively transferring heat from said heater element assembly to said rail; and
- attachment means for securing said heater element assembly to said rail such that a length of said elongate housing is aligned with a length of said rail, said attachment means comprising:
- engagement means for engaging said heater element assembly;
- bolt means for attaching said engagement means to said rail; and
- vertical adjustment means for varying a vertical distance between said bolt means and said engagement means;
- wherein, for a given position of said bolt means on said rail, said engagement means can be moved to provide a desired positioning of said heater element assembly on said rail.
- 2. The heater of claim 1, wherein said attachment means further comprises resilient means, disposed between said engagement means and said heater element assembly, for urging said heater element assembly against said rail.
- 3. The heater of claim 1, wherein said attachment means comprises means for allowing relative longitudinal motion between said heater element assembly and said rail.
- 4. The heater of claim 1, wherein said attachment means comprises a mounting surface for attachment to said rail, bracket means for engaging said heater element assembly on upwardly facing, horizontally facing and downwardly facing surfaces of said heater element assembly, and resilient means for urging said heater element assembly heat transfer surface means against said rail so as to maintain thermal contact therebetween.
- 5. The heater of claim 1, wherein said attachment means comprises bracket means for engaging said heater element assembly and resilient means, disposed between said bracket means and said heater element assembly, for urging said heater element assembly against said rail.
- 6. An apparatus for securing an elongate heater element assembly to a surface to be heated, said apparatus comprising:
- engagement means for engaging said heater element assembly;
- attachment means for attaching the engagement means to the surface to be heated; and
- resilient means, interposed between the engagement means and said heater element assembly for urging said heater element assembly against said surface to be heated.
- 7. The apparatus of claim 6, wherein said apparatus further comprises positioning means for varying a distance between said attachment means and said engagement means such that, for a given position of said attachment means on said surface, said engagement means can be moved to provide a desired positioning of said heater element assembly on said surface.
- 8. The heater of claim 6, wherein said attachment means comprises means for allowing relative longitudinal motion between said heater element assembly and said surface to be heated.
- 9. The heater of claim 6, wherein said attachment means comprises a mounting surface for attachment to said surface to be heated, bracket means for engaging said heater element assembly on upwardly facing, horizontally facing and downwardly facing surfaces of said heater element assembly, and resilient means for urging said heater element assembly heat transfer surface against said surface to be heated so as to maintain thermal contact therebetween.
- 10. The heater of claim 6, wherein said attachment means comprises bracket means for engaging said heater element assembly and resilient means, disposed between said bracket means and said heater element assembly, for urging said heater element assembly against said surface to be heated.
