Invention of "IMPROVEMENTS IN MACHINERY FOR COMBING WOOL, COTTON,

JOHN HENRY WHITEHEAD of the firm of Taylor Wordsworth and Company of
Leeds in the County of York, machine maker "IMPROVEMENTS IN MACHINERY
FOR COMBING WOOL, COTTON SILK AND OTHER FIBROUS SUBSTANCES
(A Com-
munication to me from abroad by Amèdèe Prouvost of Lille in the republic of
France)
This invention has reference to that class of combing machines in which dabbing
brushes are employed for pressing the wool or other material into the teeth of the
combs, and consists in the application of one or more thin plates (preferably of steel
or iron) which are attached to the heel of the dabbing brush where the wool first
comes in contact therewith, and in such a manner that they are surrounded by the
teeth or bristles of the dabbing brush.
In order to freely admit these thin plates into the comb I leave a larger space
between those rows of the pins (or teeth) of the combs between which the thin
plates move. By preference these plates are so attached to the dabbing brushes
that they move between the fourth and fifth rows of pins (or teeth) in the larger
comb; and between the third and the fourth rows in the smaller combs, the space
between these rows being left somewhat wider as already described.
By these means the heel of the dabbing brush is protected and the wear and
tear thereof lessened; also the wool is put much better and deeper into the comb,
thus clearing the wool much better than heretofore.

This invention has reference to that class of combing machines in which dabbing
brushes are employed for pressing the wool or other material into the teeth of the
combs, and consists in the application of one or more thin plates (preferably of steel
or iron,) which are attached to the heel of the dabbing brush where the wool first
comes in contact therewith; and in such a manner that they are surrounded by the
teeth or bristles of the dabbing brush
.
In order to freely admit these thin plates into the comb, I leave a larger space
between those rows of the pins (or teeth) of the combs between which the thin
plates move. By preference these plates are so attached to the dabbing brushes,
that they move between the fourth and fifth rows in the smaller combs, the space
between these rows being left somewhat wider as already described.
By these means the heel of the dabbing brush is protected, and the wear and
tear thereof lessened; also the wool is put much better and deeper into the comb,
thus clearing the wool much better than heretofore.
And in order that my Invention may be more readily understood reference is
given to the accompanying drawing and to the letters and marks thereon
DESCRIPTION OF DRAWINGS.
Fig 1 is a front elevation, Fig 2 is a plan, and Fig 3 is a cross section of a
dabbing brush with my Improvements applied thereto. Figs 4 to 8 shew details.
of the Improvements to be hereafter described.
a is the outer large comb circle, and b one of the inner smaller comb circles.
c is the vertical slide bar to the lower end of which the dabbing brush is attached.
The dabbing brush is made in two parts d'and e, of which d first comes in contact
with the wool. Between the body of the brush d (shewn in detail in Figs 4 and 5),
and the sole of the vertical bar c a sheet or plate of metal f, (shewn in detail in
Figs 6, 7 and 8,) is inserted, which carries the two thin vertical dabbing plates g
and h. The dabbing plate g is bent to suit the curve of the inner comb circle, and
the dabbing plate h to suit the curve of the outer comb circle, as shewn in Figs 2
and 8. Within the body of the brush & are provided two slots i and k, through
which the dabbing plates g and h are passed. (see Fig 4).
The two portions of the dabbing brush d and e are fastened to the sole of the
vertical bar c by means of the bolts and m, as shewn in Figs 1 and 2. When the
heel portion d of the dabbing brush has become clogged or otherwise requires to be
removed, it is readily detatched without altering the position of the plate f by
inserting a bolt temporarily in the hole Fig 4, which holds the plate f fixed in
position, whilst the bolt m is loosened and the heel brush d is removed and
replaced
The part e of the dabbing brush is fixed to the sole of the vertical bar c by the
bolt n.
It will be seen that by the above arrangement either one or both portious
d and e of the dabbing brush can be removed and replaced, or otherwise attended

page_text: to, without altering the position of or detaching the dabbing plates g and h after
they have once been adjusted between the rows of pins of the comb circles.
The height of the dabbing brush can be adjusted by varying the thickness of the
packing pieces o.
As the dabbing plates g and h take the greater part of the strain in forcing the
wool into the teeth of the combs, the bristles of the dabbing brush last much
longer, and besides the construction of the dabbing as herein described enables that
portion of the dabbing brush which suffers most from wear and tear to be removed.
separately and replaced.

Having now described the nature of the said Invention and shewn by the aid of
drawings how the same may be carried into practice, I would have it understood
that I do not limit myself to the precise details and configuration of the parts I
have described and shewn, as the same may be varied and modified without departing
from the nature of the said Invention but what I claim is
The arrangement construction and application of the dabbing plates g and h
in combination with dabbing brushes substantially as and for purposes herein
set forth
In Witness whereof I the said John Henry Whitehead have hereunto set
my hand and seal this Twenty third day of November in the year of Our
Lord one thousand eight hundred and eighty three
