Class 245

WIRE FABRICS AND STRUCTURE


Class Definition:
This class includes flexible all-wire or slat-and-wire fabric, wire blanks, panels and fabric structures not otherwise classifiable, and miscellaneous wire fabric joints in which at least one of the intersecting or connected elements is bent, looped, twisted, or coiled about the other or is subjected to an analogous wire-working operation to form or make the fabric or wherein wire is made an essential element of the invention. Fabrics, joints, or other structures wherein the elements are joined or secured together, for example, by tie-wires or ties, without bending or twisting the elements, or by weaving, welding, casting, nailing, and stapling and wherein wire is not made an essential element of the invention are excluded.

LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
(1) Note. Wire fabrics to which features or elements have been added which particularly adapt such fabrics for conveyor use, and which may be considered as more than an improved fabric structure, are classifiable with conveyors (see the References to Other Classes below).
(2) Note. For composite fabrics comprising fabric or web structures in which a wire fabric is used for reinforcement or protection see Search Class notes below.
(3) Note. Class 428, Stock Material or Miscellaneous Articles, subclasses 544+ is the residual locus for patents drawn to stock materials which are all metal or have adjacent metal components. As such, it provides for many rod structures analogous to wire structures and should be considered proper as a supplementary search field.
