Sealed the 24th December 1872, and dated the 6th July 1872.
PROVISIONAL SPECIFICATION left by the said John Crofts and
Richard Dawson at the Office of the Commissioners of Patents,.
with their Petition, on the 6th July 1872.
We, JOHN CROFTS and RICHARD DAWSON, both of Hunslet Lane,
Leeds, in the County of York, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN APPARATUS EMPLOYED IN COMBING WOOL AND
OTHER FIBRES," to be as follows:-
The Invention has reference to that class of combing machinery referred
to in the Specification of Letters Patent granted to us and John King,
dated June 21st, 1871, No. 1683, and the object of the present improve-
ments is to facilitate the holding of the fibre under operation as it passes
through the feed troughs.
According to one arrangement we apply teeth which rest on the fibre
as that fibre passes to the mouth piece, and we apply such teeth in a

page_text: plate hung so as to rest on the fibre with the teeth penetrating the sliver
when a receding motion takes place.
By another arrangement a roller with serrations or teeth on its surface
bears on the sliver in its passage to the mouth piece (with pressure
capable of variation by screws and springs when desired) such roller 5
being prevented from back motion by a click or stop plate.
By another arrangement teeth are applied to the lower inner surface
of the trough or to the flap or plate resting on the fibre in such trough,
or both, with the points thereof inclined in a direction towards the mouth
piece. By these means back motion of the fibre through the feed end of 1
the feed troughs is prevented.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Crofts and Richard Dawson in the Great
Seal Patent Office on the 4th January 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
CROFTS and RICHARD DAWSON, both of Hunslet Lane, Leeds, in the
County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixth day of July, in the year of our
Lord One thousand eight hundred and seventy-two, in the thirty-sixth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto us, the said John Crofts and Richard Dawson, Her special
licence, that we, the said .John Crofts and Richard Dawson, our exc-
cutors, administrators, and assigns, or such others as we, the said John
Crofts and Richard Dawson, our 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 APPARATUS EMPLOYED IN
COMBING WOOL AND OTHER FIBRES," upon the condition (amongst others)
that we, the said John Crofts and Richard Dawson, our executors or
administrators, by an instrument in writing under our or their hands
and seals, or under the hand and seal of one of us or them, should
particularly describe and ascertain the nature of the said Invention, and.

page_text: in what 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 we, the said John Crofts and Richard Dawson
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 thereof, that is to say :-
The Invention has reference to that class of combing machinery
known in the trade as Noble's, referred to in the Specification of Letters
Patent granted to us and John King, dated June 21st, 1871, No, 1683,
and the object of the present improvements is to facilitate the holding
of the fibre under operation as it passes through the feed troughs.
According to our present improvements we apply teeth which rest
on the fibre as that fibro passes to the mouth piece, and we apply such
tecth in a plate hung so as to rest on the fibre with the teeth penetrating
the sliver when a receding motion takes place. By these means back
motion of the fibre through the feed end of the feed troughs is
prevented.

page_text: is suspended as shown at its hinder end so, as, to be capable of freely
turning on the axis of motion d, and at its front end this plate carries
the teeth e, which are so placed as to penetrate the fibre just before it
enters the mouth piece b. By these means the fibre is fed on to the
circle of comb teeth more evenly, and consequently a clearer combing is
obtained with less noil.
We would state with regard to the other modifications stated in our
Provisional Specification that on further experimenting with them we
have not found them to be of that value to induce us to include them
as part of this our Final Specification. For this reason we have omitted.
further reference to them.
Having thus described our Invention and means which we adopt in
carrying the same into effect, we would have it understood that we do
not confine ourselves to the precise arrangement or combination of parts
as shewn and described, as the same may be varied without departing
from the peculiar character of our Invention, but what we do claim
is, the adaptation or combination of means whereby teeth are applied to
act on the fibre under operation as it passes through the feed troughs
of apparatus employed in combing wool and other fibre, substantially as
'described.
In witness whereof, we, the said John Crofts and Richard Dawson,,
have hereunto set our hands and scals, this First day of January,
in the year of our Lord One thousand eight hundred and seventy-
