IMPROVEMENTS IN CARDING ENGINES
Year: 1867

page_text: LETTERS PATENT to Ralph Thomas Bradbury, of Saddleworth, in the
County of York, Woollen. Manufacturer, and Thomas Bottomley, of the
same Place, Carder, for the Invention of "IMPROVEMENTS IN CARDING
ENGINES."
Sealed the 11th January 1868, and dated the 18th July 1867.
PROVISIONAL SPECIFICATION left by the said Ralph Thomas Bradbury
and Thomas Bottomley at the Office of the Commissioners of Patents,
with their Petition, on the 18th July 1867.
We, RALPH THOMAS BRADBURY, of Saddleworth, in the County of York,
Woollen Manufacturer, and THOMAS BOTTOMLEY, of the same Place, Carder,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
CARDING ENGINES," to be as follows:-
Our Invention relates to those carding engines in which a "fancy" is
employed situate above the doffer, and consists in an arrangement whereby
we are enabled to arrest small particles or flyings of material and cause them
to be conveyed to the "doffer." For this purpose we propose to employ two
stripping rollers working with each other, the one being in contact with the
"fancy" and the other with the "doffer."

page_text: Our Invention is particularly adapted to carding engines which are used for
wool or other fine fibre in different colours or conditions, for by its use the
flyings are prevented from being mixed.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Ralph Thomas Bradbury and Thomas Bottomley in the
Great Seal Patent Office on the 18th January 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, RALPH
THOMAS BRADBURY, of Saddleworth, in the County of York, Woollen Manu-
facturer, and THOMAS BOTTOMLEY, of the same Place, Carder, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighteenth day of July, in the year of our Lord One
thousand eight hundred and sixty-seven, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
Ralph Thomas Bradbury and Thomas Bottomley, Her special license that we,
the said Ralph Thomas Bradbury and Thomas Bottomley, our executors,
administrators, and assigns, or such others as we, the said Ralph Thomas
Bradbury and Thomas Bottomley, 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 "IM-
PROVEMENTS IN CARDING ENGINES," upon the condition (amongst others) that
we, the said Ralph Thomas Bradbury and Thomas Bottomley, by an instru-
ment in writing under our hands and seals, or under the hand and seal of
one of us, should particularly describe and ascertain 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 immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Ralph Thomas Bradbury, do
hereby declare the nature of our said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in
and by the following statement and accompanying Drawings, that is to
say-
"
Our Invention relates to those carding engines in which a
"fancy" is
employed situate above the "doffer," and consists in an arrangement whereby
we are enabled to arrest small particles or flyings of material and cause them

page_text: to be conveyed to the "doffer." For this purpose we propose to employ two
stripping rollers working with each other, the one being in contact with the
"fancy" and the other with the doffer.
Our Invention is specially adapted to carding engines which are used for
wool or other fine fibre in different colours or conditions, for by its use the
flyings are prevented from being mixed.
In the accompanying Drawings Fig. 1 represents a partial view of a carding
engine constructed according to our Invention, and Figs. 2 and 3 are views
in side elevation and end view of a method which may be adopted for mounting
the additional rollers. The main carding cylinder is shewn at a and the
doffer at c, at 6 is a "fancy roller" working in contact with the main cylinder
as such rollers do when called by that name. In connexion with this "fancy"
is a roller d the opposite side of which works with a roller e, which is also in
contact with the doffer c. During the operation of the machine the fancy,
as is well known, receives small particles of material or flyings, and these
according to the usual arrangement are to a great extent thrown off and may
be diffused in the room, or settle upon adjacent carding engines so as to
mingle with the material thereon, but by our Invention the fancy is stripped
by the roller d, which in its turn is stripped by the second roller c and then
the said flyings are stripped by the doffer. The direction of the wire on each
of the revolving surfaces is shewn in the Drawing, and we have also marked
such relative speeds as we have found to answer, the diameter of the main
cylinder being given as a basis. The rollers d, e, may be driven by any
convenient arrangement, but in practice we have driven them from the axes
of the two rollers f, g, as shewn in the Drawing. Figs. 2 and 3 represent as
stated the method we adopt for mounting and adjusting the rollers d, e.
To the main framework is bolted a bracket h on which there are guides i for
the reception of a sliding piece k capable of being secured in any desired
position by a bolt 1. The sliding piece k carries a screw m with a collar n on
one side of a flange o and a head p on the other, and it is in gear with a
nutq attached to the fixed bracket h. Upon the sliding piece k is an arm r
on which are formed guides s for the reception of the bearing t for the roller e,
and which may be adjusted vertically by the set screw w and confined in any
desired position by the tightening screw v. The sliding piece k also carries
another arm w provided with vertical guides x for the bearing y of the
roller d, which can be adjusted vertically by the screw u", and at x is a
tightening screw to secure any desired position, but in this instance the
arni w is free to turn when released upon the centre z, and of being fixed by
set screws 1 working in the army and abutting against a pin 2 projecting

page_text: from the sliding piece k, but the whole is fixed by the tightening screw z
before mentioned. It will therefore be seen that the two bearings t, y, and
their rollers d, e, may be moved bodily by the screw m, and that they may be
individually adjusted by the means above described.
Having thus described and ascertained the nature of our said Invention, and
the manner in which the same is to be performed, I desire it to be understood
that we claim as secured to us under the above in part recited Letters Patent,
and for the purpose above set forth, the application of rollers as illustrated
at d, e, and forming a communication between the "fancy" and the doffer.
In witness whereof, I, the said Ralph Thomas Bradbury, have hereunto
set my hand and seal, the Seventeenth day of January, in the year of
our Lord One thousand eight hundred and sixty-eight.
R. T. BRADBURY. (L.S.)
