Whitcomb L.
Judson receives a
patent for a
"Clasp Locker."
The device served
as a hook-and-
eye shoe
fastener. The
clasp locker had
its public debut
at the 1893
Chicago World's
Fair but met with
little commercial
success. Judson

6. What is a Zipper?
ZIPPER 101

7. 7
The process of opening and closing a zipper is in essence a
gearing mechanism. The zipper's teeth are the cogs of the
gear. The slider aligns the teeth in a fashion to close the
zipper, allowing each tooth to mesh with the next tooth.
When opening a zipper, the interior of the slider has a
diamond shape, which is what is forced between the teeth,
causing the “gear” to open.

Closed-End Zipper Open-End (Separating) Zipper
Structure of a Zipper
Closed-end zippers include a bottom stop that prevents the two halves from coming apart. On the other hand,
an open-end zipper is designed to completely separate when fully unzipped.

Opening Direction of a Zipper (Pin Insert)
The hand that the pin is held in when wearing the garment
determines whether the insert is left or right. In clothing designed for the US market, the pin is
on the left and the slider is on the right. The opposite is true for all other countries.

Zippers are measured by the width of the elements when
the zipper is closed. Measurement is taken in
millimeters. Most zippers start at size 3 (3 mm element
width) and go up to size 10 (10 mm element width).
