DEFINITION

Classification: 401/146

(under subclass 143) Implement wherein a force-applying means is directly effective only in the feeder or at a locus which is directly contiguous to the feeder, but not in the reservoir.

(1) Note. A pump chamber located between a reservoir and the feeder is considered to be not a part of the reservoir; even though the patent may refer to such a chamber as a 'reservoir' or 'reservoir portion'. Such a chamber will be recognized in the disclosure by wall structure setting off the locus as being distinct from the reservoir space. For example, wall structure which is contiguous to the feeder and so conforms to a piston moving therealong as to make the piston effective at said locus only will be recognized as defining a pump chamber and will not be considered as part of the reservoir, even though in direct communication therewith.

SEE OR SEARCH THIS CLASS, SUBCLASS:

13, for a patent including force-applying means at, or adjacent, the tool to withdraw excess material applied to a work surface back into the implement.

151, for an implement including a plurality of reservoirs or reservoir portions in series, one of which may be directly contiguous to the feeder, and including force-applying means to cause flow of material from one reservoir or portion to another.

184+, for an implement whose force-applying means is a manually engageable, resilient wall portion which may be at the discharge end of an otherwise rigid-wall reservoir.
