230. 3. Pointing. (a) A man next takes about three hundred of
these straightened pieces in a parcel, and putting them into a
gauge, cuts off from one end, by means of a pair of shears, moved
by his foot, a portion equal in length to rather more than six
pins. He continues this operation until the entire parcel is
reduced into similar pieces. (b) The next step is to sharpen the
ends: for this purpose the operator sits before a steel mill,
which is kept rapidly revolving: it consists of a cylinder about
six inches in diameter, and two and a half inches broad, faced
with steel, which is cut in the manner of a file. Another
cylinder is fixed on the same axis at a few inches distant; the
file on the edge of which is of a finer kind, and is used for
finishing off the points. The workman now takes up a parcel of
the wires between the finger and thumb of each hand, and presses
the ends obliquely on the mill, taking care with his fingers and
thumbs to make each wire slowly revolve upon its axis. Having
thus pointed all the pieces at one end, he reverses them, and
performs the same operation on the other. This process requires
considerable skill, but it is not unhealthy; whilst the similar
process in needlemaking is remarkably destructive of health. (c)
The pieces now pointed at both ends, are next placed in gauges,
and the pointed ends are cut off, by means of shears, to the
proper length of which the pins are to be made. The remaining
portions of the wire are now equal to about four pins in length,
and are again pointed at each end, and their lengths again cut
off. This process is repeated a third time, and the small portion
of wire left in the middle is thrown amongst the waste, to be
melted along with the dust arising from the sharpening. It is
usual for a man, his wife, and a child, to join in performing
these processes; and they are paid at the rate of five farthings
per pound. They can point from thirty-four to thirty-six and a
half pounds per day, and gain from 6s. 6d. to 7s., which may be
apportioned thus; 5s. 6d. the man. 1s. the woman, 6d. to the boy
or girl.
