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.
