Sealed the 16th December 1870, and dated the 1st September 1870:
PROVISIONAL SPECIFICATION left by the said Archibald Turner at
the Office of the Commissioners of Patents, with his Petition, on the
1st September 1870.
I, ARCHIBALD TURNER, of Leicester, in the County of Leicester,
Elastic Fabric Manufacturer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR PRINTING
YARNS OR WARPS FOR CARPETS OR OTHER FABRICS," to be as follows:-
My Invention relates to that class of machinery for printing yarns in
which the yarns to be printed are wound round a large cylinder and the

page_text: colour is laid on by means of a roller which as it rotates takes up the
colour from a box mounted on a carriage which is made to traverse to
and fro the length of the large cylinder.
My first improvement relates to the construction of the colour roller
and the adaptation thereto of certain devices for preventing the colour
roller from taking up and laying on too much colour. To this end the
roller is made of metal instead of wood and its periphery or circumference
(which takes up the colour from the colour box in which it is mounted)
is made concave, so as to hold the colour in the centre and prevent it
from being deposited in ridges at the edges. In combination with the
colour roller make-use-of-a-doctor-or scraper at each side of or rather
at back and front of the colour roller for the purpose of scraping off the
superfluous colour from the roller as the roller rotates in the colour
trough. These doctors or scrapers are made to act on the periphery and
also on both sides of the edge. The concave periphery will thus take up
and lay on the warp exactly the quantity of colour required.
The object of this improvement is to lay on the proper quantity of
colour and no more, and to lay it on to the yarns as evenly as possible.
This is effected very well by my improvements, but when the colour has
been deposited or laid on to the yarns by the colour roller it must be
rubbed in so as to rub the colour through and dye all the yarus equally;
this has heretofore been done by means of scrapers worked by hand, but
although attempts have been made to do this mechanically by means of
rollers which have been made to follow the colour roller and press the
colour into the yarn this so far as I am aware has not been successfully
accomplished.
The second part of my Invention consists in adapting to the travelling
frame or carriage which carries the colour roller instruments which I
will call spreaders, inasmuch as they collect such colour as is left in
ridges by the colour roller and spread it evenly over and press or force
it through that part of the yarn which is intended to be coloured. That
part of my improved instrument which comes in contact with the yarn
and may be termed the foot, is about one-third of an inch wide, and
three-quarters of an inch long. It is made hollow or with a triangular
or other shaped recess or with transverse or diagonal ridges, so that as
the instrument passes over the yarn it will scrape and collect the colour
into the recess from which it will be delivered and spread in a smooth
and even line of the proper width by the toe or nib of the instrument.

page_text: I prefer this construction of instrument because it collects any excess of
colour that may have been laid on by the colour roller into the recess and
delivers it out in a regulated quantity and even manner, but I sometimes
use a spreader consisting simply of a blunt edge mounted in such
a manner that its working edge will be placed diagonally to the line of
travel, so that as it collects the superfluous colour it pushes it over the
path of the colour roller and spreads it evenly on and rubs or presses it
into the yarn. If desired two of these instruments may be used in
conjunction, but arranged with their diagonal working edges in opposite
directions.
It should be understood that there must be a spreading instrument or
instruments both at the back and front of the colour roller and these
instruments are made to act alternately, the one in action being that
which follows the colour roller.
The spreaders are mounted on rocking shafts to which are adapted
weights or springs for keeping the spreaders up to their work, that is,
against the yarns on the large cylinder according to the amount of
pressure required.
