Class 112
SEWING
Class Definition:
This is the generic locus for patents for (1) sewing
machines, (2) methods of sewing, and (3) stock material
products of a sewing operation. This class is also residual
for patents for sewn articles which are not specifically
provided for in any other class.
SCOPE OF THE CLASS
Sewing is the operation of uniting or ornamenting material by
means of a strand which is inserted (stitched) in the
material at spaced locations by a needle having an eye, or
equivalent structure, and enchained or otherwise locked in
position.
With the addition of product subclasses, no change has been
made in the relationship of this class with other classes in
regard to patents for machines and processes. See Lines With
Other Classes and Within This Class, below, for the reference
to product subclasses.
LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
PRODUCT SUBCLASSES
With the addition of product subclasses 400-441, inclusive,
no change has been made in the relationship of this class
with other classes in regard to patents for machines and
processes.
Regarding patents for products, it is intended that only such
patents in which layers have been secured together, or a
strand has been affixed to a base, solely by a stitching
operation shall be placed in this class. However, patents for
such products which include structure which is the result of
an operation which may be considered ancillary to the
stitching operation (e.g., manipulating, folding, cutting) or
which include merely a description of the sewn material
(e.g., woven, knitted, braided, carded, twisted) will not be
excluded from this class.
A patent for a stock material product resulting from a
combined operation (e.g., sewn and coated or bonded) will be
placed in an appropriate subclass in Class 428, Stock
Material or Miscellaneous Articles, and see the main
definition of that class, (428), section V1 A 1.
It is recognized that patents for sewn stock material may be
found in other classes. No attempt has been made at this time
to collect such patents in this class. It is expected that
when such other classes are reclassified, sewn stock material
patents will be transferred to this class (112).
Search notes to related classes will be found under the
definition of subclass 400 for products, subclass 2 for
apparatus, and subclass 262.1 for methods.

GLOSSARY:
BLIND STITCH
A stitch in which the sewing thread penetrates only one
nonthickness surface of a layer or component. See Figure 1.
[figure]
COMPONENT
A distinct unitary element of a composite web or sheet which
is longitudinally coextensive therewith and which, if
separated from said multi-part web or sheet, would be
recognized as a web or sheet by itself.
A component may consist of plural layers as in the folded
component shown in Figure 2. [figure]
COMPOSITE SHEET
A sheet comprising a plurality of components.
COMPOSITE WEB
A web comprising a plurality of components.
CONCEALED STITCH
A stitch in which the sewing thread completely penetrates one
or more layers of material and is hidden from view on at
least one side of the assembly by a fold of material
overlying the stitch. See Figure 3. [figure]
FIBER
A relatively short, slender, flexible element of macroscopic
size and finite length and having a width and thickness of
the same order magnitude. A fiber is generally of staple
length to facilitate being spun, twisted, or otherwise
secured together into a composite strand but may be of
shorter length requiring bonding, felting, or matting to form
a strand or layer. It may be of animal (e.g., wool, rabbit
hair); vegetable (e.g., cotton, jute, hemp); or mineral
(e.g., asbestos, glass, metal) origin; and may be either
natural, modified, or synthetic.
LAYER
A single thickness of material or materials in the form of a
panel, web, or sheet, or a plurality of any of these in
side-by-side coplanar relation, or particulate material
arranged in continuity to constitute a distinct stratum.
A layer may include a plurality of components as in Figure 4.
[figure]
NONTHICKNESS SURFACE
The surface of a web, sheet, layer, or component on which
both its length and width may be measured. See Figure 5.
[figure]
OVEREDGE STITCH
A stitch wherein the sewing thread extends thickness-wise
across a marginal extremity of one or more layers of material
without penetrating side extremity. See Figure 6. [figure]
PANEL
A portion of material of finite perimeter having length and
width greater than thickness and (a) having a modification or
embellishment of or on the entire periphery thereof or at
least two nonadjacent corners, (b) being completely enclosed
in an envelope which substantially conforms thereto, or (c)
having a boundary shape which is other than rectangle.
SHEET
A rectangular portion of material of finite length and width
which are each greater than its thickness. A piece of
material having a peripheral shape other than rectangular
will be considered a panel.
STRAND
A relatively slender and flexible element having a width and
thickness of the same order of magnitude and a length which
is either (a) indeterminate or (b) coextensive with the
length or width of a sheet or layer. A strand may be a
monofilament or it may include either a plurality of
filaments or fibers disposed in parallelism (e.g., tow) or
constituent fibers and/or filaments knitted, plaited,
braided, twisted, interlaced, interlocked, or otherwise
secured together to form a unit such as roving, thread yarn,
cord, rope or cable.
STRAND PORTION
A strand of finite length; or an unsevered but determinate
part of a strand.
STRIP
A web or sheet of relatively narrow ribbon-like material. A
strip which is interwoven or intertangled with other strips
or strands in the same manner as a strand will be termed a
"strand-like strip".
WEB
A portion of material having length and width each greater
than its thickness and with at least its longitudinal
dimension undetermined.
A web may comprise (a) a single thickness of material, (b) a
plurality of portions of a single piece of material folded
onto each other longitudinally or transversely, or (c) a
plurality of individual web components joined together in
longitudinally coextensive face or edge contact to form a
composite web.
