DEFINITION

Classification: 401/29

(under the class definition) Implement including more than one coating tool*, an enclosing member for at least one of said tools, and means to cause or permit relative movement between said one tool and its enclosing member, without complete separation, to the extent that the tool may alternately occupy an exposed operative position and an inoperative position wherein the tool is retained in concealed position within said enclosing member.

(1) Note. A patent for an implement including a plurality of pieces of solid material for rubbing contact and means for selectively causing or permitting movement of each piece between operative and inoperative position will be placed in this subclass if each piece is provided with a carrier which cooperates with the means for causing or permitting movement. However, a patent wherein the implement includes only a single means which is directly engageable with a selected piece of such solid material to cause or permit movement of the piece through an opening in a guide member between operative and inoperative position will be placed elsewhere (see Search This Class, Subclass)

(2) Note. A patent in which a spare tool-and-reservoir unit is removable from a storage compartment of the implement and is adapted to be reassembled with the implement so as to be in use position, to replace an expended unit, will be placed in a subclass appropriate to the particular disclosed tool

(e.g., for a ball point pen).

SEE OR SEARCH THIS CLASS, SUBCLASS:

16+, for an implement comprising diverse tools including at least one projectable and retractable tool.

49+, for patents wherein the implement includes only a single means which is directly engageable with a selected piece of such solid material to cause or permit movement of the piece through an opening in a guide member between operative and inoperative position, particularly subclass 56 where the implement includes positive means for causing, rather than merely permitting, such movement.. 55+, for an implement including means to project and retract a piece of solid material for rubbing contact; particularly indented subclasses 56 for such an implement including means for selectively replenishing its feed guide from any one of a plurality of storage compartments, 57 for such an implement including means for sequentially replenishing its feed guide from storage means, and 85 for such an implement including means for storing other such pieces in nonuse position for manual removal and association with the projection-retraction means.

88+, for an implement including means to guide a manually movable piece of solid material between nonuse and use positions; and indented subclass 89 for this combination further including means to store an additional piece of material in nonuse position.

99+, for an implement including a single, linearly projectable and retractable tool which is other than solid material for rubbing contact.

209+, for a ball point pen.
