Year: 1865

page_text: LETTERS PATENT to Charles Walker and William Preston, of Batley-
Carr, in the County of York, Overlookers, for the Invention of "IMPROVE-
MENTS IN MACHINERY FOR CARDING WOOL OR OTHER FIBROUS SUBSTANCES."
PROVISIONAL SPECIFICATION left by the said Charles Walker and
William Preston at the Office of the Commissioners of Patents, with
their Petition, on the 3rd October 1865.
We, CHARLES WALKER and WILLIAM PRESTON, of Batley-Carr, in the
County of York, Overlookers, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MACHINERY FOR CARDING WOOL OR OTHER
FIBROUS SUBSTANCES," to be as follows:-
.
This Invention relates to the machine known as the "scribbler
carding engine, and by which wool or other fibrous substance is carded and
formed into roping, or a continuous sliver which is deposited ou a creeper
and thereby conducted to the feeding end of the second carder. When
carding short stapled wool or other fibrous substances great difficulty is
experienced in maintaining the continuity of the sliver or roping, the frequent
breakage of which is very objectionable, and heretofore "cone-tins" as conical.
friction rollers have been employed to support the fibres as they are doffed

page_text: from the cards, and which by a slight pressure thereon are inten led to assist
in the formation of the roping which is effected by a combined process of
twisting and drawing: These appliances do not, however, prevent the
breakage of the sliver or roping, but are frequently the cause of breakage by
sticking or getting out of order:
Now our improvements consist in dispensing with these cone rollers and
substituting a flap hinged under the doffer extending across the machine, and
which is caused to flap or oscillate by means of crank motion actuated from
any convenient-moving part of the machine, thereby constantly, flapping,
batting, or pressing the fibrous substances as they are doffed from the card
surface during the process of twisting and drawing or the formation of the
roping by which breakage is prevented. and the roping more evenly formed.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles Walker and William Preston in the Great Seal
Patent Office on the 3rd April 1866., :
TO ALL TO WHOM THESE PRESENTS SHALL 'COME, "o, "CHARLES
Ek hid Wilta PRESTON, of Batley Caif, in the County of York,
Overlookers, send greeting
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of October, in the year of our Lord Oue
thousand eight hundred and sixty-five, in the twenty-ninth year of Her reign,
'did, för Herself, Her heirs and successors, give and grant unto ris, 'the'said
Charles Walker and William Preston, Hèr special licence that we, the
said Charles Walker and Williain Preston, our executors, administrator's, and
assigns, or such others as we, the said Charles Walker and William Preston,
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,
ud vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
MACHINERY FOR CARDING WOOL OR OTHER FIBROUS SUBSTANCES," upon the condition
(amongst others) that we, the said Charles Walker and William Preston, our
executors or administrators, by an instrument in writing 'under 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 per
forined, and cause the same to be filed in the Great Seal Patent Office

page_text: Within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that we, the said Charles Walker and William Preston,
ilo 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, that is to, say :-
:
"
This Invention relates to the machine known as the "scribbler" or first carding
engine; and by which wool or other fibrous substance is carded and formed
into roping or a continuous sliver which is deposited on a creeper and
thereby conducted to the feeding end of another "scribbler" or carder. When
carding short stapled wool or other fibrous substances great difficulty is
experienced in maintaining the continuity of the sliver or roping, the frequent
breakage of which is objectionable, and heretofore "cone tins" or conical
friction rollers have been employed to support the fibres as they are doffed
from the cards, and which by a slight pressure thereon are intended to assist
in the formation of the roping which is effected by a combined process of
twisting and drawing. These appliances do not, however, prevent the
breakage of the sliver or roping, but are frequently the cause of breakage by
sticking or getting out of order. :
☐ Now our improvements consist in dispensing with these cone rollers and
substituting a flap hinged under the doffer, extending across the machine, and
which is caused to flap or oscillate by means of crank motion actuated from
any convenient moving part of the machine, thereby constantly flapping,
batting, or pressing the fibrous substances as they are doffed from the card
surface during the process of twisting and drawing, or the formation of the
roping, by which breakage 'is prevented and the roping is more evenly formed.
The manner in which this Invention is or may be performed or carried into
practice will be readily understood by those conversant with this class of
machinery, and the usual process of forming ropings by the following
description: This flap may be constructed of tin, zinc, 'sheet iron, wood, or
other material made smooth of about four or five inches in breadth, and. in
length to the full width of the cards or length of the doffer cylinder. It is
fixed by one edge on a bar or shaft of sufficient length to be mounted at each
end in a bearing fixed on the side frames of the engine about vertically under
the doffing plate of the doffer. A lever arm is fixed on one end of the shaft,
to which a connecting. rod is attached at one end, and the other to a crank
arm, which may be fixed on one of the card-roller shafts or on a counter-
shaft provided for the purpose, and receiving its motion from any roller shaft
or other shaft of the engine, so as to regulate or obtain such suitable speed for

page_text: operating the flap as may be found requisite in practice. It will now be
easily perceived that during the working of the engine and the formation of
ropings of the carded fibrous substance' as it is doffed from the cards the flap
will be caused to oscillate upon its shaft to such extent as may be arranged
for by the throw of the crank and length of the lever arm, thereby striking,
beating, patting, or pressing against the roping during the process of
formation at each oscillation, by which means the roping is supported or
prevented from dropping and breaking its continuity whilst undergoing the
process of drawing and twisting, and at the time when it has received little or
no twist to hold it together. It will also be evident that although we have
herein described the means of operating this flap to be by crank and rod, it
may be operated by eccentric and rod, or by a tappet or cam, or by star wheel
and spring, or balance weight, or by other mechanical means, such as may be
found most convenient according to circumstances.
Having thus fully described the nature of this our said Invention, and the
manner in which the same is to be or may be performed, we would have it
distinctly understood that we do not confine or restrict ourselves to any
particular construction or mode of operation, but what we claim as of our
Invention, and which we believe to be new within the realm is, the application
and use of a moveable flap, beater, or presser, in the manner and for the
purpose substantially as herein described.
In witness whereof, we, the said Charles Walker and William Preston,
have hereunto set our hands and seals, this Twenty-ninth day of
March, One thousand eight hundred and sixty-six.
Signed, sealed, and delivered by the
within-named Charles Walker
and William Preston, in the
presence of
STEPHEN ASKHAM.
