DEFINITION

Classification: 432/239

(under the class definition) A subcombination of a heating device, specialized for use in heating, for feeding or discharging a work chamber or for conveying or agitating work while within such chamber.

SEE OR SEARCH THIS CLASS, SUBCLASS:

53, for a work unit handler interrelated with a furnace closure or heating element operator.

86, for a furnace having associated means for receiving work from the discharge means.

87, for a furnace having associated means for supplying the furnace feed means.

95+, for a gravity flow type shaft furnace through which work is moved by gravity. 96, for a shaft furnace having an agitator or movably mounted baffle for the shaft outlet.

103+, for a rotary drum-type furnace for tumbling work material.

121+, for a furnace having heating structure and being of the type in which a charge is progressed or moved mechanically.

157, for a furnace for heating material in a crucible or pot and mounted to discharge the crucible or pot by tilting to pour melted material.

160, for a combustion gas heated furnace or furnace work holder mounted for tilting discharge.

162, for a combustion gas heated furnace charged by a movably mounted shelf, rack or tray.

211, for an externally heated liquid holding type of work container mounted for pouring discharge.

234, for a protectively cooled work skid or rail.

235, for a protectively cooled conveyor, chute, or work agitator element.

110, Furnaces,

101, for a means for feeding solid fuel into a combustion furnace. 198, Conveyors: Power-Driven, appropriate subclass for a power driven conveyor or conveyor element, per se, of general utility.

221, Article Dispensing, appropriate subclass for a means dispensing articles or arranging them in a chamber for dispensing.

222, Dispensing, appropriate subclass for a residual process

or apparatus for dispensing fluent material.

366, Agitating, appropriate subclass for an agitator, per se, or one having merely nominally recited heating or cooling means.

414, Material or Article Handling,

147+, for the combination of a chamber of a type utilized for a heating function and material charging or discharging means therefor. Specific furnace structure is included there (147+) only when its sole purpose is to facilitate the movement of material to or from the chamber furnace. See also subclasses 586+ for a device or element associated with the handling or moving of a charge for a heating-type chamber.
