DEFINITION

Classification: 414/147

CHAMBER OF A TYPE UTILIZED FOR A HEATING FUNCTION AND MATERIAL CHARGING OR DISCHARGING MEANS THEREFOR:

(under the class definition) Apparatus comprising a receptacle-like structure (e.g., furnace, oven, etc.) of a kind adapted to be provided with means for heating it, and means for moving, or enabling gravity movement of, either (a) material in the nature of work which is to be heated in the structure, or (b) material in the nature of fuel which is to be consumed during a work-heating operation, to, adjacent to, into, out of, from, within, etc., the structure.

(1) Note. While the basic concept of this and the indented subclasses is that of the combination of the chamber and the means for charging or discharging material thereto of therefrom, rigid adherence to that concept would have resulted in a considerable scattering of the art of the predecessor area (subclasses 18-37 of former Class 214). Accordingly, claims to the charging or discharging means are originally classifiable here (with the below-mentioned exception) if the claims make clear, or if such is the sole disclosure, that the destination of source of the material is a chamber of the kind under consideration. However, exceptions are made in the instance of a charging or discharging means which is proper for Class 198, or one which is proper for some other area of this class (414), in which event original classification is there and the patent is cross-referenced to this area (147+).

(2) Note. The claiming of, for example, (a) a heating chamber and heating means therefor, with or without a charging or discharging means, or (b) structure of a heating chamber which relates only to its heating function (e.g., lining, configuration, etc.) or (c) discharging work which is molten in form, and is handled as a liquid (e.g., not merely as the contents of a receptacle), from a heating chamber, presents subject matter which is beyond the scope of this class (414).
