DEFINITION

Classification: 401/49

(under the class definition) Implement comprising (1) a support# adapted to utilize a piece of nonfluent, cohesive, self-sustaining coating material and to allow an end or surface of said piece to be applied directly to a work surface, or (2) a piece of such material, an end or surface of which is specifically shaped to adapt it to be applied directly to a work surface.

(1) Note. The work engaging end or surface of the piece of solid material constitutes the tool* and the rest of the piece is the supply.

(2) Note. A patent claiming no more than a piece of solid coating material having a shaped end for contacting the work

will be placed in this, rather than an indented subclass even though the disclosure indicates the piece as being intended for use in a combination provided for in such indented subclass.

(3) Note. See the Search Notes, below to subclasses 1, 29+, 34+, 37+, 118+, and 208+, for loci for devices which store coating material in a solid form but apply portions of it by means of a tool, frequently after converting the material to a fluent state.

(4) Note. A disclosure that material is extruded through an orifice is an indication that the material is fluent and therefore is not in the form of a nonfluent, cohesive, self-sustaining piece, as required by the definition of this subclass. A patent to a coating implement utilizing such extrudable material will be placed elsewhere in this class, based on other features; see the search notes below to other subclasses in this class. For example, tooth paste, thick enough to retain its extruded shape when squeezed from a tube but which is wiped from the tube opening onto a surface, rather than applied in stick form, is not considered solid material for the purpose of this subclass; however, a self-sustaining semi-solid material (e.g., lip stick) of such consistency as to be attrited, rather than flowed upon a surface, is considered solid material for this subclass.

(5) Note. A patent to solid coating material claimed in terms of its cross-sectional configuration will be placed in the appropriate class providing for stock material. See the class definition for Class 428, Stock Material or Miscellaneous Articles, for the relationship of that class (428) to various other stock material classes. (6) Note. A patent to a piece of solid coating material, per se, claimed as a composition with no more than nominally expressed structure, as "bar," "rod," "block," "layer," "stick," "strand," "strip," etc., will be placed in the appropriate composition class. The various composition classes are listed in order of superiority in the class definition of Class 106, Compositions: Coating or Plastic.

(7) Note. For placement of a patent to a holder# of general utility, in which the tool is either not claimed or only broadly claimed, see the last paragraph of Scope of This Class, in the Class Definition of Class 401.

(8) Note. An implement will be considered to include only a single tool, with provision for supply of additional pieces of material, when the implement includes only a single means to cause or permit movement of a piece of material through an opening in a guide# to a use position, which single means is selectively associable directly with a single one of a plurality of pieces of solid coating material. However, the implement will be considered to have plural tools, and a patent thereto will be placed in subclasses 29+, when the implement has a single means to cause or permit such movement

of a selectable one of a plurality of units, each of which units comprises a piece of solid coating material and a carrier# specifically provided for the purpose of selective association with said means; and see (1) Note to the definition of subclass 29.

(9) Note. A single holder with two or more pieces of solid material, or with a single piece having two exposed ends, each piece or end having a surface positioned for use (e.g., a wooden pencil with different colored leads exposed at each end) will be considered an implement having plural tools for placement in subclass 34, unless one of said tools is projectable and retractable, in which case the patent to the implement will be placed in subclasses 29+.

(10) Note. The Glossary terms at the end of this subclass, which occur in the titles and definitions of this and indented subclasses, are defined below. The symbol (#) following a word or phrase indicates that reference should be had to this glossary for the specific meaning thereof. Terms which are used in the titles and definitions of this class as a whole are defined in the Glossary, of the Class 401 class definition.

SEE OR SEARCH THIS CLASS, SUBCLASS:

1+, for an implement of this class provided with means for heating solid material, as for rendering it fluent.

19+, for an implement with solid coating material for rubbing contact and including a coating tool of some other species (e.g., pen or brush).

29+, and 34+, for an implement comprising two or more tools of solid material for rubbing contact.

37+, for a device including a container for a supply of solid or pasty material and a plurality of brushes, one of which removes a portion of the material from the container for application to a work surface; particularly subclass 38, wherein said one brush is separable from the container for such application.

40+, for an implement including means retaining soluble or dispersible solid material and supply-means* for a liquid carrier in which the solid material is dissolved or dispersed before application to a work surface. 118+, for a device which includes a container for a solid or pasty material and an independent applicator for receiving material from the supply and applying it directly to the work; particularly, subclass 126, wherein the applicator is, or is attached to, a closure for the container and is thus retained in communication with the supply.

200, for an implement including a pervious tool through which particulate solid material may sift.

201, for a porous tool provided with a pocket for soluble solid material.

208+, for an implement with solid material supply which is not rubbed directly on the work, but is deposited on a roller tool which applies it to a work surface.

309, for applying solid treating material to the body.

CARRIER

A member attached to a piece of solid coating material so as to be movable therewith in a guide#.

EXPENDABLE- SHEATH-

A holder# for a piece of solid coating material which is adapted or required to have a portion thereof, adjacent the tool*, removed so as to expose the coating material as it is attrited in use. See HOLDER. FOLLOWER

A member movable in a guide# and adapted to contact a piece of solid coating material therein to advance it to and through the opening in response to an applied force.

GUIDE

That part of an implement which defines a path of travel for a piece of solid coating material to and through an opening in the implement to a use position of the tool* end of the piece.

HOLDER

That part of an implement which retains a piece of solid coating material, or which retains a unit consisting of a piece and an expendable sheath, in such a manner as to expose the tool* end of the piece and to be manipulable therewith as a single entity (e.g., sleeve, wrapper). The holder and the piece, or the holder and the unit, may be relatively adjustable manually, but not by advancing means (as defined in subclass 55).

SUPPORT

All the parts of an implement, collectively, which retain the piece. It may be a holder# or it may include a carrier,# or follower, and a guide# as well as a housing for enclosing the entire organization of parts.
