Class 163
NEEDLE AND PIN MAKING
Class Definition:
This class contains special apparatus and processes for the
manufacture of crocheting, knitting, and sewing needles, both
for hand and machine use; also, machines and processes for
making garment-fastening pins of the ordinary form, as well
as safety pins. All such single operations as bending,
swaging, groove-milling, point-grinding, turning, and the
like will be found in appropriate subclasses under the
corresponding fuctional title.

SUBCLASSES
Subclass:
1
Miscellaneous devices for completing the manufacture or for
performing two or more operations upon sewing-needles for
either hand or machine use.

451, Abrading, subclass 315 for a needle-eye polisher.
Subclass:
2
Machines and the like for making hook-ended needles for
knitting or crocheting fabrics.
Subclass:
3
Special machines for making tongued needles for
knitting-machines or for attaching the tongues or latches to
the bodies of such needles.
Subclass:
4
Needle-making machines having sets of grippers radially
arranged on a circular carrier which has a step-by-step
rotation to bring the needle-blanks into position to be
operated upon by the various shaping devices. In some cases a
plurality of carriers is shown, together with means for
transferring the blank from one carrier to another.
SEE OR SEARCH CLASS:
221, Article Dispensing, subclasses 217+ for article
dispensers, not otherwise classified, which have endless belt
or rotary mounted gripper-type discharge assistants,
subclasses 224+ for article dispensers having manipulating
means subsequent to discharge from a source of supply, and
subclasses 239 and 294 for article dispensers feeding to
clamp or holddown means. See the class definition of Class
221 for a statement of the line between the classes and for
the disposition of other similar disclosures.
470, Threaded, Headed Fastener, or Washer Making: Process and
Apparatus, subclass 129 for similar carriers.
Subclass:
5
Miscellaneous methods of making sewing and knitting needles,
both for hand and machine use.
