_Klauder-Weldon Hank-dyeing Machine._--This is illustrated in (p. 048)
figure 15, which shows the latest form. It consists of a
half-cylindrical dye-vat built of wood. On a central axis is built two
discs or rod carriers, which can revolve in the dye-vat, the
revolution being given by suitable gearing which is shown at the side
of the machine. On the outer edge of the discs are clips for carrying
rods on which one end of the hanks of yarn is hung, while the other
end is placed on a similar rod carrier near the axle. The revolution
of the discs carries the yarn through the dye-liquor contained in the
lower semi-cylindrical part of the machine previously alluded to. (p. 049)
At a certain point in every revolution of the discs the rods carrying
the yarns are turned a little; this causes the yarn to move on the
rods, and this motion helps to bring about greater evenness of dyeing.
The most modern form of this machine is provided with an arrangement
by means of which the whole batch of yarn can be lifted out of the
dye-liquor. Arrangements are made by which from time to time fresh
quantities of dyes can be added if required to bring up the dyed yarn
to any desired shade. This machine works well and gives good results.
Beyond the necessary labour in charging and discharging, and a little
attention from time to time as the operation proceeds, to see if the
dyeing is coming up to shade, the machine requires little attention.

Many other forms of hank-dyeing machine have been devised. There is
Corron's, in which an ordinary rectangular dye-vat is used. Round this
is a framework which carries a lifting and falling arrangement that
travels to and fro along the vat. The hanks of yarn are hung on rods
of a special construction designed to open them out in a manner as
nearly approaching hand work as is possible. The machine works in this
way. The lifting arrangement is at one end of the vat, the hanks are
hung on the rods and placed in the vat. Then the lifter is set in
motion and moves along the vat; as it does so it lifts up each rod
full of yarn, turns it over, opening out the yarn in so doing, then it
drops it again in the vat. When it has travelled to the end of the vat
it returns, packing up the rods of yarn in so doing, and this motion
is kept up until the dyeing is completed. This machine is very
ingenious.
