DEFINITION

Classification: 366/150.1

HAVING SPECIFIED FEED MEANS:

(under the class definition) An apparatus or corresponding method including a particularly described means for conveying or admitting material (i.e., feed means) into the mixing chamber.

(1) Note. Mere recitation of an opening, inlet port, or feed conduit for the material is not considered specified feed means. However, any of the following claimed particulars are considered specified means for this subclass: (a) means applying positive or negative pressure on material to move it into the chamber (e.g., pump); (b) conveyor means (e.g., belt, screw, chute); (c) feed control means (e.g., valve, gate); (d) structure determining the proportions of different materials fed to the chamber; (e) a feed conduit extending into the mixing chamber or in tangential relation to the chamber; (f) a plurality of feed means (conduits, chutes, hoppers, etc.) in a particular relation to each other or to the mixing chamber; or (g) a supply reservoir and means to feed material from the reservoir into the chamber.

SEE OR SEARCH THIS CLASS, SUBCLASS:

27+, 30+, and 40, for a mortar mixer type apparatus having means for feeding material into a mixing chamber.

76, for a rubber or heavy plastic working apparatus having specified feed means.

131, for a device wherein the feed means and the discharge means are interrelated.

SEE OR SEARCH CLASS 222, Dispensing, appropriate subclasses, for material dispensing apparatus, per se. See References to Other Classes in the Class definition of this class (366) for the line between Class 366 and Class 222.
