Abstract
Abstract Heating apparatus including a radiation source and reflector means for focussing reflected rays at an image focus. The source of radiant energy and reflector means are mounted upon an adjustable support which is linearly movable in a vertical direction to position a heating apparatus above a working surface. The working surface is comprised of means movable in two mutually perpendicular directions within a plane perpendicular to the direction of movement of said heating apparatus. Said means is further adapted to receive and support the object to be heated. Indicator means located outside of the heating area, is coupled to the heating apparatus and includes pointer means adaptable to be positioned immediately above the region of the object to be heated. The support assembly is initially moved to a first position. The object to be heated is placed upon the supporting means which, together with the eating apparatus is adjusted to place the indicator so as to rest upon the object to be heated. After adjustment, the supporting apparatus is then moved to a second working position whereby the adjustments previously made rapidly and accurately locate the object to be heated exactly in the focal image of the reflector means. Further means may be provided for locking the supporting surface in position to prevent its jarring when moved into the working position. Also, novel reflector means may be provided for projecting the object being heated upon a screen for viewing purposes to accurately control the level of heating required whereby the radiation employed for heating is utilized as the illuminating source for the projection apparatus.
