IMPROVEMENTS IN MACHINES FOR PREPARINGUS
Year: 1860

page_text: LETTERS PATENT to John Legg Lupton and Joseph Bleasdale, both of
Church, near Accrington, in the County of Lancaster, Roller Makers,
for the Invention of "IMPROVEMENTS IN MACHINES FOR PREPARING AND
Sealed the 27th July 1860, and dated the 9th February 1860.
PROVISIONAL SPECIFICATION left by the said John Clegg Lupton and
Joseph Bleasdale at the Office of the Commissioners of Patents, with
their Petition, on the 9th February 1860.
We, JOHN CLEGG LUPTON and JOSEPH BLEASDALE, both of Church, near
Accrington, in the County of Lancaster, Roller Makers, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN MACHINES FOR PREPARING
AND SPINNING COTTON AND OTHER FIBROUS MATERIALS," to be as follows:-
Our Invention relates to the drawing rollers of machines used in preparing
and spinning, and it consists in dispensing with the flannel and leather with
which top rollers are usually covered, and making the whole set of top and
bottom drawing rollers, or any part thereof, with flutes on their circumferences,
the said flutes being rounded at the top and bottom so as to take firm hold of
the fibrous material passing between the drawing rollers without cutting or
injuring it.
Another part of our Invention consists in making drawing rollers without
flutes, and in placing one top roller above and between two bottom rollers.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Clegg Lupton and Joseph Bleasdale in the Great Seal
Patent Office on the 2nd August 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
CLEGG LUPTON and JOSEPH BLEASDALE, both of Church, near Accrington, in
the County of Lancaster, Roller Makers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of February, in the year of our Lord One
thousand eight hundred and sixty, in the twenty-third year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
John Clegg Lupton and Joseph Bleasdale, Her special licence that we, the
said John Clegg Lupton and Joseph Bleasdale, our executors, administrators,
and assigns, or such others as we, the said John Clegg Lupton and Joseph
Bleasdale, 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 MACHINES FOR
PREPARING AND SPINNING COTTON AND OTHER FIBROUS MATERIALS," upon the con-
dition (amongst others) that we, the said John Clegg Lupton and Joseph
Bleasdale, our executors or administrators, by an instrument in writing under
our or their, or one of our or their hands and seals, 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 we, the said John Clegg Lupton and Joseph
Bleasdale, do hereby declare the nature of our said Invention, and in wh
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement (that is to say) :-
Our Invention relates to the drawing rollers of machines used in preparing
and spinning, and it consists in certain improved modes of constructing the
said drawing rollers, whereby the coverings of flannel and leather usually
applied to the top rollers are dispensed with.
In performing our Invention we make the whole set of top drawing rollers,
or any part thereof, with flutes on their circumferences, the said flutes being
rounded at the top and bottom so as to take firm hold of the fibrous material

page_text: Fig. 1 is a section through a set of drawing rollers suitable for a drawing
frame, and constructed according to our improvements; a, b, c, and d, are the
bottom drawing rollers, and e, f, g, and h, are the top rollers; the flutes in all
these rollers are rounded off at the top and bottom to prevent them injuring or
cutting the cotton or other fibrous material passing between them.
The object of our Invention is to economise the labor and material now
employed in covering top rollers, which in a large establishment amounts to a
very considerable sum, as each top roller requires to be covered several times
in a year.
Another advantage is produced by the firm hold obtained by our
improved top rollers on the fibrous materials, and it consists in being able to
reduce the weights which are suspended by hooks or bridles to the top rollers,
by this means the friction is reduced and the bearings and necks are less
injured by wear; the action of the drawing rollers is also more even on the
fibrous material to be operated upon.
We wish to remark that, although we have only shewn our improvements
applied to the drawing rollers of a drawing frame, they are equally applicable
to all machinery used in preparing and spinning cotton and other fibrous
materials when drawing rollers are employed. In some cases it may be pre-
ferable to apply a top roller covered with flannel and leather in the usual
manner to the front drawing roller.
Fig. 2 is a section through a pair of drawing rollers constructed according
to another of our improvements; in this case the bottom rollers i, j, are with-
out flutes, and to top roller k fits between the two bottom rollers; the top
roller may be covered with flannel and leather or other suitable material, or it
may be plain as shewn.
Fig. 3 represents a modification of this part of our Invention, the position
of the rollers is reversed, that is to say, there is only one bottom roller i to
two top rollers k, k; by this arrangement the fibrous materials are securely
held by the double hold obtained between the top and bottom rollers, and a

page_text: very even drawing of the fibres is produced. The rollers shewn in Figs. 2 and
3 may be used in combination with our improved drawing rollers, or combined
with drawing rollers of the ordinary construction.
Having thus stated the nature of our Invention, and described the manner
of performing the same, we declare that we claim,―
First, the improved mode of constructing the flutes of drawing rollers as
shewn and described in reference to Fig. 1.
And, secondly, the application of a single top roller to a double row
of plain bottom rollers, or vice versa, as shewn and described in reference to
Figs. 2 and 3.
In witness whereof, I, the said Joseph Bleasdale, have hereunto set my
hand and seal, this Thirty-first day of July, in the year of our Lord
One thousand eight hundred and sixty.
JOSEPH DLEASDALE. (L.S.)
