~. MACHINE that makes pine
N turns out 1900 of these tiny
NJ essentials an hour. Before
the pin is finished it goes
through very many operations, which
are described in the Youths Compan-
ion as follows: A reel of wire hangs
over the machine, che free end OF
which passes between two rollers.
As the wire leaves the roller it passes
between two matched dies until it
touches guage. Just as it does this
the dies come together and clamp it
firmly in groove in their face. At
the same time the machine cuts it of
the proper length. The gauge then
moves away and little punch forms
the bead by striking the end which
rested against the guage. When this
is finished the dies separate and de-
liver the pin into one of the great
many grooves in the face of the wheel
about q foot in diameter, and just as
wide across its face as the pin is long.
When the pin is taken by the wheel
it hes no point, but as the wheel turns
it rubs the pins against an outside
band, which causes each one to roll n
its groove, and at the same time carries
them past q set of rapidly moving flesI
which brush against the blunt ends
and sharpens them roughly. They
next pass against the faces OF two
grinding wheels, which smooth the
points, and then to . rapidly moving
leather band having fine emery glued
on It's face. This gives them the fnal
polish, and as they leave the band they
are dropped into box underneath
the machine. After this the pins are
plated with tin to give them bright,
silvery appearances. They are pre-
pared for plating by being first i'm;
mersed in weak s,1lphuric acid to re-
move all grease, and then dried by
being placed-a bushel or SO at q
time, with about the same quantity OF
sawdust-in q machine called tnm-
bling barrel. This is simply cask
suspended on a shaft which passes
through it 1engthwise. Two or three
hours rolling in sawdust cleans the
pins snd wears away any little rough
ness which the machine may have
caused.
Pins and sewdust are taken TO-
gether from the barrel and allowed to
fall in steady stream through blast
of air. The sawdust, being the Lighter,
is blown over into large, room-like
box, while tho pins, being heavier,
fall into bin below. After this they
are spread out in trays having sheets
of zinc in thei- bottoms, which have
previously been connected with one
of the wire. of sn electric battery.
The trays are then placed in tank
containing . solution OF tin in muriatic
acid, and the other wire of the battery
is inserted in the solution. Electrical
actioa immediately begins and deposits
metallic tin on the entire surface OF
each pin. They are then washed In a
tank of water and put into other
tumbling barrels with hot sawdust.
When they have been dried and cleaned
Of the sawdust, as in the former in
stance, they are put into a large,
slowly revolving oopfer-lined tub.
which is tilted st an angle Of about
forty-fve degrees. As this revolvea
the pins keep sliding down the smooth
copper to the lower side. This con-
slant rubbing against the tub sns
against each other polishes them.
It was the practice formerly to allow
pins Of all lengths to become mixed in
the different operations, and, after
polishing, to separate them by very
ingenious machine, but it has been
found more economical to keep each
size to itself.
From the polishing tub the pins are
carried to the 'tsticker," where they
fall from a hopper on an inclined plane
in which are q number Of slits. The
pins catch in these sljts and hanging
By their heads, slide down the incline
to the apparatus which inserts them in
tho paper. As the number Of pins in
q row on the paper and the number:ot
slits are the same, an entire row Is
stuck at once by An ingenious device
which takes one pin from each slit and
inserts them all at once III the two
ridges which have been crimped in the
paper by wheel that holds it in place
to receive the pins. At the same time
the wheel crimpa the paper it spaces
the rows, so that when filed with pins
the paper will fold up properly.
This whole machine is so delicate in
it's action that single bent OF. other
wise imperfect pin will cause the
machine to stop feeding until the at
tendant remove it; yet its operation
is 30 rapid that one machine will stick
1000 pinsan hour. As the long strip
Of paper on which the pins are stuck
comes from the machine it is cut into
proper lengths by girls, who then fold
and pack the papers in bundles ready
for shipment
