CERTAIN IMPROVEMENTS IN CARDING ENGINES
Year: 1866

page_text: LETTERS PATENT to John Baron and Edward Tattersall, both of Heywood,
in the County of Lancaster, Spinners and Manufacturers, for the Inven-
tion of "CERTAIN IMPROVEMENTS IN CARDING ENGINES."
Sealed the 26th October 1866, and dated the 30th April 1866.
PROVISIONAL SPECIFICATION left by the said John Baron and Edward.
Tattersall at the Office of the Commissioners of Patents, with their.
Petition, on the 30th April 1866.
We, JOHN BARON and EDWARD TATTERSALL, both of Heywood, in the County
of Lancaster, Spinners and Manufacturers, do hereby declare the nature of.
the said Invention for "CERTAIN IMPROVEMENTS IN CARDING ENGINES," to be
as follows:-
The Invention relates to the description of machinery used in preparing
fibrous substances called carding engines, and is designed to dispense with the
ordinary guide plate used to support the "fleece" of fibrous material as it is
doffed from the card cylinder, and the improvements consist in the application

page_text: and use of a plate or bar placed at a short distance from the doffing cylinder
and between the doffing comb and the calendering rollers; this plate, bar, or
support extends parallel to the axis of the cylinder and across the width of the
engine, and projects upwards sufficiently to support the "fleece " in its passage
from the cylinder to the rollers, and by the use and substitution of such plate
or bar instead of the usual deep angular guide plate, space occupied by the
engine is economized, a better and firmer edge or selvedge is given to the
fleece," and thereby the breaking and consequent "fly" and waste is
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Baron and Edward Tattersall in the Great Seal Patent
Office on the 30th October 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
BARON and EDWARD TATTERSALL, both of Heywood, in the County of Lan-
caster, Spinners and Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of April, in the year of our Lord
One thousand eight hundred and sixty-six, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said John Baron and Edward Tattersall, Her special license that we,
the said John Baron and Edward Tattersall, our executors, administrators,,
and assigns, or such others as we, the said John Baron and Edward Tat-
tersall, 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 "CERTAIN IMPROVE-
MENTS IN CARDING ENGINES," upon the condition (amongst others) that we, the
said Johu Baron and Edward Tattersall, our executors or administrators, by
an instrument in writing. under our, or one of our, or their, or one of 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 I, the said Edward Tattersall, do hereby
declare the nature of the said Invention, and in what manner the same

page_text: .
is to be performed, to be particularly described and ascertained in
and by the following statement and accompanying Drawings (that is to
say):
The Invention relates to the description of machinery used in preparing
fibrous substances called carding engines, and is designed-to dispence with the
ordinary guide, plate used to support the fleece of fibrous material as it is
doffed from the card cylinder, and the improvements consist in the application
and use of a plate or bar placed at a short distance from the doffing cylinder
and between the doffing comb and the calendering rollers; this plate, bar, or
support extends parallel to the axis of the cylinder and across the width of
the engine, and projects upwards sufficiently to support the "fleece" in its
passage from the cylinder to the rollers, and by the use and substitution of
such plate or bar instead of the usual deep angular guide plate the space
occupied by the engine is economized, a better and firmer edge or selvage is
given to the "fleece," and thereby the breaking and consequently the "fly"
and waste is prevented.
In order that the Invention may be better understood and explained in
detail we have hereunto attached a Sheet of Drawings made upon a scale of
about three inches to the foot, and having similar letters of reference marked
upon corresponding parts.
Fig. 2 represents a plan view of that portion of the carding engine to which
the improved guide plate is attached, and Fig. 2 represents a vertical section
of the "doffer cylinder" and guide plate.
In Figs. 1 and 2 a, a, is the doffer cylinder; b, b, the comb stock; and c,
the calendering rollers, all being well-known parts of the carding engine. At
a short distance from the surface of the cards of the doffing cylinder and
parallel with its axis the guide plate d, d, is fixed, and extends the whole width
of the front bearing plate e. The doffing comb 6 is situated directly above the
guide plate e, and the calendering rollers close in front; by this arrangement
the space usually occupied by this part of the machine is materially econo-
mized and a better selvage is produced on the "fleece," and the shorter
staple of cotton is operated upon with less waste or fly than by the ordinary
method.
Having now described the nature of the said Invention, together with the
method of carrying the same into practical effect, I wish it to be distinctly
understood that we claim the application and use of the said plate or bar
extending across the width of the machine and parallel to the axis of the
doffing cylinder, whether employed with the ordinary "draw-box" or guide,

page_text: or without, as herein-before described, set forth, and fully illustrated in the
Drawings attached.
In witness whereof, I, the said Edward Tattersall, have hereunto set my
band and seal, this Twenty-ninth day of October, in the year of our Lord
One thousand eight hundred and sixty-six.
