IMPROVEMENTS IN MACHINERY OR APPARATUS FOR PREPARING COTTON AND OTHER FIBROUS MATERIALS TO BE SPUN
Year: 1861

page_text: LETTERS PATENT to William Crighton and Frederick William Crigh-
ton, of the City of Manchester, in the County of Lancaster, Machinists,
for the Invention of "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR
PREPARING COTTON AND OTHER FIBROUS MATERIALS TO BE SPUN."
Sealed the 28th June 1861, and dated the 3rd April 1861..
PROVISIONAL SPECIFICATION left by the said William Crighton and
Frederick William Crighton at the Office of the Commissioners of
Patents, with their Petition, on the 3rd April 1861.
We, WILLIAM CRIGHTON and FREDERICK WILLIAM CRIGHTON, of the City
of Manchester, in the County of Lancaster, Machinists, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS
FOR PREPARING COTTON AND OTHER FIBROUS MATERIALS TO BE SPUN," to be as.
follows:-
In a cage or grid we place a vertical beater or cylinder with arms or teeth
of any suitable form fixed thereto; the cylinder may be made conical, if
desired. These improvements are partly applicable to Hardacre's opener, the
points of difference being that in Hardacre's the cotton or material is fed in at
the top of the machine, and in its passage downwards the dirt or refuse, by the
centrifugal force of the beater, is expelled through the grid or grate, and is
liable to mix. with the fibrous material; but by our plan the cotton or material

page_text: being fed at the bottom or other convenient part of the surface of the cylinder
(except the top), is carried upwards, and the dirt or refuse is driven out in its
passage by the centrifugal force of the beater through the bars of the grid or
grate; the material thus passing upwards and the dirt downwards, they are
more effectually separated.
We also use a series of travelling dirt boxes between the delivering part of
the cylinder or beater and the dust cage, which may be made to travel in any
direction, either from the beater to the dust cage or vice versa, or from side to
side of the cotton passage; the said dirt boxes may be made of any suitable
form or shape, and we prefer them- travelling from the cage to the beater, as
the material being thus blown in one direction and the dirt in the other, they
will be more effectually separated. This part of our Invention is also appli-
cable to scutchers, blowers, or carding engines.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Crighton and Frederick William Crighton in the
Great Seal Patent Office on the 2nd October 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
CRIGHTON and FREDERICK WILLIAM CRIGHTON, of the City of Manchester, in
the County of Lancaster, Machinists, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of April, in the year of our Lord One
thousand eight hundred and sixty-one, in the twenty-fourth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
William Crighton and Frederick William Crighton, Her special licence that
we, the said William Crighton and Frederick William Crighton, our execu-
tors, administrators, and assigns, or such others as we, the said William
Crighton and Frederick William Crighton, 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 66
IMPROVEMENTS IN MACHINERY OR APPARATUS FOR PREPARING
COTTON AND OTHER FIBROUS MATERIALS TO BE SPUN," upon the condition (amongst
others) that we, the said William Crighton and Frederick William Crighton,
our executors or administrators, by an instrument in writing under our, or
their, or one of their hands and seals, should particularly describe and ascer-

page_text: thin the nature of the said Invention, and 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 inmediately after the date of the said
Letters Patent.
NOW KNOW YE, that we, the said William Crighton and Frederick William
Crighton, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed; to be particularly described and ascer-
tained in and by the following statement (that is to say) :-
These improvements are partly applicable to Hardacre's opener, in which
the cotton or material is fed in at the top of the machine, and in. its passage
downwards the dirt or refuse is expelled through the grid or grate, and is
liable to mix with the fibrous material. In order to overcome this imperfection
we cause the cotton or material to be fed at the bottom or other convenient
part of the surface of the cylinder (except the top), and carried upwards, and
the dirt or refuse is driven out in its passage by the centrifugal force of the
beater through the bars of the grid or grate; the material thus passing
upwards and the dirt downwards, they are more effectually separated than in
Hardacre's opener.
We also employ a series of travelling grids or dirt boxes of any suitable
form between the delivery part of the cylinder or beater and the dust cage,
and also apply the travelling dirt boxes to scutchers, blowers, lap machines, and
carding engines.

"
This Invention will be clearly understood by referring to the letters marked
on the accompanying Drawing, representing a vertical section of an opener,"
with our improvements applied.
a, a, represents a grid or cage in which we place the vertical cylinder or
beater b, having fixed to it arms or teeth c of any suitable form, the cylinder
being made parallel or conical, as may be desired. The cotton or material is
fed through the pipe d and carried upwards, the dirt or refuse being expelled
through the bars of the grid or cage a. The travelling dirt boxes are shewn
at e; they work between the delivery part of the cylinder or beater and the
dust cage g. The said travelling dirt boxes are made of any required shape,
and are also applicable to scutchers, blowers, lap machines, and carding
engines.
Having now described the nature and particulars of our said Invention, and
the manner in which the same is to be performed, we desire it to be understood
that we claim as our Invention, and which to the best of our knowledge and
belief has not been hitherto used within the realm, the improvements in ma-
chinery or apparatus for preparing cotton and other fibrous materials to

page_text: be spun, as herein described and illustrated in the accompanying Sheet of
Drawings.
In witness whereof, we, the said William Crighton and Frederick
William Crighton, have hereunto set our hands and seals, this First
day of October, in the year of our Lord One thousand eight hundred 5
and sixty one
