Year: 1878

page_text: LETTERS PATENT to William Terry and John Scott, of Dudley Hill, near
Bradford, in the County of York, Commission Wool Combers, for the Invention
of "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR COMBING WOOL AND
OTHER FIBROUS SUBSTANCES."
Sealed the 7th February 1879, and dated the 10th August 1878.
PROVISIONAL SPECIFICATION left by the said William Terry and John Scott
at the Office of the Commissioners of Patents on the 10th August 1878...
WILLIAM TERRY and JOHN SCOTT, of Dudley Hill, near Bradford, in the County
of York, Commission Wool Combers. "IMPROVEMENTS IN MACHINERY OR APPA
RATUS FOR COMBING WOOL AND OTHER FIBROUS SUBSTANCES."...:
The object of this Invention is to dispense with the use of dabbing brushes in
Noble's and other circular combs.
For this purpose, we employ a roller covered with cloth, felt, or india-rubber, or
other flexible or porous substance, which will be easily penetrated by the comb
teeth, and this roller we fix at the tangent point of the circles in such a manner
that the teeth of the combs shall penetrate the roller and cause it to revolve at the
same surface speed. The wool or other fibrous material in passing underneath the
roller is pressed into the combs, and on leaving the roller it passes under holding or
pressing knives which force it still deeper into the combs and prevents it from
rising out of the teeth during the seperation thereof.

page_text: If necessary, the knife in the outer or larger circle may have a rising-and-falling
motion imparted to it at the end nearest the pressing roller to facilatate the pressing
of the material into the comb.
SPECIFICATION in. pursuance of the conditions of the Letters Patent filed by
the said William Terry and John Scott in the Great Seal Patent Office on the
10th February 1879.

WILLIAM TERRY and JOHN SCOTT, of Dudley Hill, near Bradford, in the County
of York, Commission Wool Combers. "IMPROVEMENTS IN MACHINERY OR APPA-
RATUS FOR COMBING WOOL AND OTHER FIBROUS. SUBSTANCES."
The object of this Invention is to dispense with the use of the reciprocating
dabbing brushes in "Noble's" and other circular combs.
For this purpose, we employ a roller or rollers covered with cloth, felt, india-
rubber, bristles, or other flexible or porous substance, of such a nature as to offer
little resistance to the points of the comb teeth, and these rollers we fix at the
tangent point of the circles in such a manner that they shall revolve at the same
surface speed combs. The wool or other fibrous substance in passing under-
neath the rollers is pressed into the combs, and on leaving the roller it passes under
holding or pressing knives which force it still deeper into the combs and prevent it
from rising out of the teeth during the separation thereof.
If necessary, the knife in the outer or larger circle may have a rising-and-falling
motion imparted to it at the end nearest the pressing rollers to facilitate the pressing
of the material into the comb.
In order that our Invention may be more fully understood, we have hereto
annexed a Sheet of Drawings illustrative thereof.
Fig. 1 represents plan view of such parts of a Noble's comb as are necessary to
illustrate our Invention; Fig. 2 is sectional elevation of same; and Figs. 3 and 4
are enlarged views of the rollers covered with bristles.
A is the large circular comb and B the smaller circular comb arranged in the
usual manner. C are a series of rollers covered on the periphery with bristles, and
-placed at an angle, as shewn in views, Figs. 3 and 4. These rollers are placed loose
on the short shaft or stud D supported by bracket E attached to the pillar F.
These rollers are caused to revolve by frictional contact with, and at the same
surface speed as the large circular comb A, pushing or pressing the wool into the
teeth of the comb continuously as it revolves, and on leaving the rollers it passes
under the holding-down plate G, which forces it deeper and prevent its rising out
of the teeth during the separation thereof. H is a separate roller covered with
bristles, employed for pressing wool into the small circular comb B.
C
Another method of carrying out this Invention is shewn in Figs. 5, 6, and 7,
which are plan view, section, and elevation respectively.
In this method, two of the rollers are removed, and in place thereof are fixed
-holding-down knives I and J. In this case the brushes are dispensed with, and, in

page_text: lieu thereof the rollers are covered with cloth, felt, india-rubber, or other flexible
material which will not damage or take off the points of the teeth. Figs. 8 and 9
are enlarged details of these rollers shewing the cloth, felt, or other material placed
on the periphery.
In either of the methods herein shewn and described it will at once be seen that
as the wool or other fibre is passing underneath the rollers that it will be pressed
into the combs of the large and small circles, and by means of the holding-down
plates or knives the wool is kept well in the comb until the separation takes place.
By the use of this Invention, the combs can be run quicker than they possibly
could be by the reciprocating "dabbing brushes" now in use.
In witness whereof, I, the said John Scott, for and on behalf of myself and
the said William Terry, have hereunto set my hand and seal, this First
day of February, in the year of our Lord One thousand eight hundred and
seventy-nine.
