Babbage, Charles, 1792-1871

"On the Economy of Machinery and Manufactures"

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.
231. 4. Twisting and cutting the heads. The next process is
making the heads. For this purpose (a) a boy takes a piece of
wire, of the same diameter as the pin to be headed, which he
fixes on an axis that can be made to revolve rapidly by means of
a wheel and strap connected with it. This wire is called the
mould. He then takes a smaller wire, which having passed through
an eye in a small tool held in his left hand, he fixes close to
the bottom of the mould. The mould is now made to revolve rapidly
by means of the right hand, and the smaller wire coils round it
until it has covered the whole length of the mould. The boy now
cuts the end of the spiral connected with the foot of the mould,
and draws it off. (b) When a sufficient quantity of heading is
thus made, a man takes from thirteen to twenty of these spirals
in his left hand, between his thumb and three outer fingers:
these he places in such a manner that two turns of the spiral
shall be beyond the upper edge of a pair of shears, and with the
forefinger of the same hand he feels that only two turns do so
project.
