TIE MAKING oE PINS.
PROCESSES Employed in the Manufacture
ofthe Indiarensnhle Little Things.

Processes Employed In the Manufa cturs
ofthe Indispensable Little Things.
The manufacture of pin was te.
dious process when entirely made by
hand; no less than twelve or fourteen
processes had it to pass through be-
fore it was completed. The wonderful
machinery now in use has much sim
plified matters. First of all the wire
must be prepared. 1t is placed in a
coil on a revolving block, and drawn
through holes pierced in steel plate,
until it is of the size required for the
particular pin to be made. 1t is then
taken to the pin-malSing room, where
we find rows of machines moved by
steam power. and producing constant
stream of pins at the rate of 180 to 220
per minute, which are removed from
the receptacles into which they fall by
the workman and his attendants, who
look after the proper working of the
machines.
II we stand in front of machine we
see coil of brass wire on a revolving
drum. The end of the wire passes
through hole, and then between iron
pegs. which straighten the wire and
keep it in its place as it is drawn into
the machine. In the machine we see a
pair of sliding pincers take hold of the
wire, carry it forward a short distance,
and put the end through hole in a
small iron plate. Watch carefully, and
we see pretty little hammer strike
the end as soon as it appears on the
other side of the iron plate. BY sue
cessive blows of this hammer the head
is made. This done, down falls sharp
blade and cuts the wire into the length
required for the pin (the machine can
be adjusted to cut the pins of any
length desired.) This process of draw
ing in, heading, and cutting off goes
on continually, and the pins are thus
carried on to the pointing part of the
machine.
The pointless pin now falls into
,slanting groove, just wide enough fer
it, but too narrow to let the head
through. Thus we see row of pins
hanging by their heads nearly the
is a revolving cylindrical file. The sur
face of the cylinder represents a series
of graduated files, on which as they
are worked backwards and forwards
the pins are pointed. They fall into a
receptacle below, but as yet they are
yellow--the color of brass wire; they
are also greasy. They are now put into |
which are turned round and |
round, and by this means thoroughly |
secured and cleaned, and are ready to |
be ''silvered." They are now put into
kettles heated by steam, and spread
about as evenly as possible. A powder
)f fine tin is then spread over them,
md certain portion of acid added.
In this they are boiled for about two
hours. When taken out they are found
% be covered with thin coating of
in, which gives them the bright and
ilvery appearance which all pins pos
less.
The pins are then dried by being
brown into sawdust, and polished by
icing put into barrels revolved by ma
hinery. Thence they are placed in
lat tray, and the workman, by peculiar
ossing motion. which requires much
kill, separates all the dust from the
'ins, which are now clean, bright and
eady for use. There is a very ingen-
Gus machine used for "stickingn the !
ins which are to be sent to the market
n papers. The paper is placed on a
iece of curved metal, and crimped ,
nd placed in position to receive the ,
ins, which are passed out of a recep-
icle at the top of the machine by +,
irl, who with brush deXterously 7
weeps them into grooves placed in an !,
lclined plane leading down to the :
aper. Thus arranged, they pass down ;,
lie machine in long lines, and by =
'ver the paper is brought under the y
Oints of a row OF pins, and by beau -
full bit of machinery they are pressed :
trough the crimped edges of the i
aper. Thus row by row the whole :,
leet is filled. Queen.
