Year: 1869

page_text: LETTERS PATENT to John Edward Millar, of Sowerby, in the Parish
of Halifax, in the County of York, Cloth Finishing Manager, for
the Invention of "IMPROVEMENTS IN MACHINERY OR APPARATUS TO BE
APPLIED TO THE TEAZLES OR CARDS EMPLOYED FOR RAISING THE NAP OF
WOOLLEN CLOTH."
Sealed the 11th January 1870, and dated the 16th July 1869.
PROVISIONAL SPECIFICATION left by the said John Edward Millar
at the Office of the Commissioners of Patents, with his Petition,
on the 16th July 1869.
I, JOHN EDWARD MILLAR, of Sowerby, in the Parish of Halifax,
in the County of York, Cloth Finishing Manager, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN MACHINERY OR
APPARATUS TO BE APPLIED TO THE TEAZLES OR CARDS EMPLOYED FOR RAISING THE
NAP OF WOOLLEN CLOTH," to be as follows:-
This Invention relates to the construction and use of apparatus for
cleaning or removing the loose fibre from the teazles or cards employed
for raising the nap of woollen cloth whilst such machinery is in operation,

page_text: and without removing the "gig rods' which hold or secure the teazles
on the raising cylinder, which I effect as follows:-
I employ a cylindrical, helical, or spiral brush supported on bearings
extending across and parallel with the raising cylinder, rotary motion is
imparted to this brush by pulley and strap or driving band. The brush
which I construct of what is known as "hard weed" (in preference to
ordinary bristles) is in contact with the teazles or cards of the raising
cylinder, and the spiral arrangement of the bristles when revolving effect
a slight traverse through the teazles, thereby removing the loose fibre
from the bent or hooked points without damage to the teazles.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Edward Millar in the Great Seal Patent
Office on the 14th January 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
EDWARD MILLAR, of Sowerby, in the Parish of Halifax, in the County
of York, Cloth Finishing Manager, send grecting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixteenth day of July, in the year of
our Lord One thousand eight hundred and sixty-nine, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John Edward Millar, Her special
licence that I, the said John Edward Millar, my executors, adminis-
trators, and assigns, or such others as I, the said John Edward
Millar, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for IMPROVEMENTS IN MACHINERY OR APPARATUS TO BE APPLIED TO THE
TEAZLES OR CARDS EMPLOYED FOR RAISING THE NAP OF WOOLLEN CLOTH,"
upon the condition (amongst others) that I, the said John Edward
Millar, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and scals, should particularly
describe and ascertain the nature of the said Invention, and in what
66

page_text: manner the same was to be performed, and cause the same to be filed in
the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Edward Millar, do hereby
declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained
in and by the following statement :-
This Invention relates to the construction and use of apparatus for
cleansing or removing the loose fibre from the teazles or cards employed
for raising the nap of wollen cloth, whilst such machinery is in
operation and without removing the " gig rods" which hold or secure
the teazles on the raising cylinder, which I effect as follows:-
I employ a cylindrical, helical, or spiral brush supported on bearings
extending across and parrallel with the raising cylinder, rotary motion is
imparted to this brush by pully and strap or driving band. The brush
which I construct of what is known as "hard weed" (in preference to
ordinary bristles) is in contact with the teazles or cards of the raising
cylinder, and the spiral arrangements of the bristles when revolving
effect.a slight traverse through the teazles, thereby removing the loose
fibre from the bent or hooked points without damage to the teazles.
Such being the nature and object of this my said Invention I will
now proceed to describe the same fully, and in order that the same may
be clearly understood I have hereunto annexed a Sheet of Drawings and
have marked the same with Figures and letters of reference, the same
letter referring to the same part in the various views or figures;
Figure 1 is a side view of a "gig" or machine for purposes above
referred to; Figure 2 is a front view of the same with appliances
attached according to this Invention; Figure 3 is a detail view.
A, A, on the side frames; B is the cylinder; at D is shewn the brush
for removing the loose fibre from the teazles on the cylinder B; E, E, are
arms or cranks supporting the brush, the said arms or cranks being
placed on the ends of the cross shaft F which is supported by brackets
F, F, bolted to the side frames; G is a side shaft supported in
fixings g, g, one end of the shaft G is chased or screwed as shewn and
worked through the lug or projection H; on the other end of the said
side shaft is a hand wheel I, by turning which the screwed or chased end
of this shaft will remove the brush from contact with the teazles on the
cylinder, so that when desirable such cylinder may revolve clear of the

page_text: brush, and also serves for regulating the degree of contact of the bristles
of the brush with the teazles on the cylinder; J, J, are fast and loose
pully for driving the brush, the strap K working on or over ordinary
drum or pully.
Having thus fully described and ascertained the nature.and particulars
of this my said Invention for Improvements in Machinery or Apparatus
to be applied to the Teazles or Cards Employed for Raising the Nap of
Woollen Cloths," together with the manner in which the same is to be
or may be performed or carried into practical effect, I wish it to be
distinctly understood that I claim as my Invention,―
Firstly. The use and application of the spiral or helical formed
brush, constructed in the manner and for the purpose herein described
and,illustrated.
Secondly. The construction, application, and arrangement of the arms
or cranks for supporting the said brush, together with the cross shaft,
side shaft, and hand wheel, for adjusting the brush as herein described
and illustrated.
Lastly. The general construction and arrangement of the several parts
herein specially referred to as contributing my Invention.
In witness whereof, the said John Edward Millar, have here-
unto set my hand and seal, this Thirteenth day of January,
in the year of our Lord One thousand eight hundred and
seventy.
