fitted on an axle;
these discs carry strong hooks on which the hanks are placed. The
operator places a hank on a pair of the hooks. The discs revolve and
carry round the hank, during the revolution the hank is twisted and the
surplus liquor wrung out, when the revolution of the discs carries the
hank to the spot where it entered the machine the hooks fly back to
their original position, the hank unwinds, it is then removed and a new
hank put in its place, and so the machine works on, hanks being put on
and off as required. The capacity of such a machine is great, and the
efficiency of its working good.
Mr. S. Spencer of Whitefield makes a hank-wringing machine which
consists of a pair of hooks placed over a vat. One of the hooks is
fixed, the other is made to rotate. A hank hung between the hooks is
naturally twisted, and all the surplus liquor wrung out. The liquor
falling into the vat.
_Roller Squeezing Machines for Yarn._--Hanks may be passed through a
pair of indiarubber squeezing rollers, which may be so arranged that
they can be fixed as required on the dye-bath. Such a pair of rollers is
a familiar article, and quite common and in general use in dye houses.
_Piece Goods._--These are generally passed open through a pair of
squeezing rollers which are often attached to the dye-vat in which the
pieces are dyed.
_Read Holliday's Squeezing Machine._--In Fig. 31 is shown a squeezing
machine very largely employed for squeezing all kinds of piece goods
and cotton warps after dyeing or washing. It consists of a pair of heavy
rollers on which, by means of the screws shown at the top, a very
considerable pressure can be brought to bear. The piece is run through
the eye shown on the left, by which it is made into a rope form, then
over the guiding rollers and between the squeezing rollers, and into
waggons for conveyance to other machines. This machine is effective.
Another plan on which roller, or rather in this case disc, squeezing
machines is made, is to make the bottom roller with a square groove in
the centre, into this fits a disc, the cloth passing between them. The
top disc can by suitable screws be made to press upon the cloth in the
groove, and thus squeeze the water out of it.
=Washing.=--One of the most important operations following that of
dyeing is the washing with water to free the goods, whether cotton or
woollen, from all traces of loose dye, acids, mordanting materials,
etc., which it is not
