DEFINITION

Classification: 15/257.07

(under subclass 257.05) Apparatus wherein the supply containing means is adapted to contain ink.

(1) Note. The apparatus will be recognized as a dispenser for Class 222, Dispensing, when means for receiving and loading a pen is a trap chamber as defined in section 11 (see, particularly, clause (1) of the first paragraph), of the definition of Class 222; i.e., said means not only separates a quantity of ink from the contained supply but maintains it (indefinitely) for access thereto by a penpoint.

(2) Note. This, the principal subclass, includes patents to devices (1) containing a supply of pigment and (2) means for retaining a liquid vehicle in a position to permit contact with the pigment for solution therewith or dispersal therein to make ink. A patent disclosing such a device, but classified in an indented subclass herein below because of (further) novelty relevant to the indented subclass, must be cross-referenced in this subclass (257.07).

108, Horizontally Supported Planar Surfaces,

26.2, for an inkwell which is attached to a horizontally disposed surface of a desk. 141, Fluent Material Handling, With Receiver or Receiver Coacting Means,

20.5, for the combination of a pen and a source of ink, which source has means for producing force to move material from the source to the pen for application, by the pen, to a surface remote from the source; and see Class 401, Coating Implements With Material Supply, subclasses 118+, for a correspondingly comprehensive combination, but which includes no material-moving force-producing means in the source (although it may be present in the pen).

211, Supports: Racks,

69.2+, for the combination of an ink receptacle and a pen support.

215, Bottles and Jars, and 220, Receptacles, appropriate subclasses for an inkwell without pen-loading facilities structure to distinguish it, respectively, from any other general utility bottle or jar, or from a general utility receptacle.

222, Dispensing,

576+, for dispensing inkwells; i.e., including a supply of ink and a trap chamber which is a dip well for receiving ink in the following manner: subclasses 578+, by nongravity means subclass 583, by dipping into the supply; subclass 584, by tilting the entire organization; and subclasses 585+, by barometric feed.

312, Supports: Cabinet Structure,

232, for cabinet structure which includes an inkwell.

401, Coating Implements With Material Supply,

118+,. (See the search note to Class 141, above).
