Abstract
Abstract A radiant heater includes a tilting and focusing reflector and a burner which is mounted inside of the reflector. The reflector can be tilted to direct radiant energy from the burner in a desired direction, and the focal point of the reflector can be moved with respect to the burner to concentrate, direct, or disperse radiant energy.

Total Claims: 4
Claim 1
Independent Claim
211 words
A radiant heater combining a base, a reflector mounted on the base, the reflector including a curved reflecting wall having a focal point, a burner tube mounted on the base and extending through an opening in the reflector, a burner head on the end of the burner tube, a pair of spaced-apart elongated mounting members mounted on the base, slide means mounted on each mounting member and being movable along a portion of the length of the mounting member for slidably supporting the reflector, and pivot means mounted on each of the slide means for pivotally supporting the reflector whereby the reflector is pivotably mounted on the base to permit tilting movement of the reflector relative to the burner head and the slide means are movable along the spaced-part elongated mounting members to permit movement of the curved reflecting wall of the reflector and the focal point thereof toward and away from the burner head so that radiant heat energy from the burner can be focused and dispersed by the reflector wall, the reflector including a parabolic rear reflecting wall and a pair of flat sidewalls, said means for pivotally mounting the reflector providing a pivoting axis for the reflector which extends through the sidewalls forwardly of the parabolic rear wall.

A radiant heater combining a base, a reflector mounted on the base, the reflector including a curved reflecting wall having a focal point, a burner tube mounted on the base and extending through an opening in the reflector, a burner head on the end of the burner tube, a pair of spaced-apart elongated mounting members mounted on the base, slide means mounted on each mounting member and being movable along a portion of the length of the mounting member for slidably supporting the reflector, and pivot means mounted on each of the slide means for pivotally supporting the reflector whereby the reflector is pivotably mounted on the base to permit tilting movement of the reflector relative to the burner head and the slide means are movable along the spaced-part elongated mounting members to permit movement of the curved reflecting wall of the reflector and the focal point thereof toward and away from the burner head so that radiant heat energy from the burner can be focused and dispersed by the reflector wall, the reflector including a parabolic rear reflecting wall and a pair of flat sidewalls, said means for pivotally mounting the reflector providing a pivoting axis for the reflector which extends through the sidewalls forwardly of the parabolic rear wall.
Claim 3
Dependent Claim
22 words
The heater of claim 1 in which the pivoting axis is generally aligned with the focal point of the parabolic rear wall.
Claim 4
Dependent Claim
26 words
The heater of claim 1 in which means are provided on each slide to releasably position the slide and thereby prevent movement along the elongated member.
