IMPROVEMENTS IN CARDING ENGINES
Year: 1872

page_text: LETTERS PATENT to Samuel Brooke, of the Firm of Samuel Brooke
and Company, of Brighouse, in the County of York, Card Makers,
for the Invention of "IMPROVEMENTS IN CARDING ENGINES."
Sealed the 4th April 1873, and dated the 8th October 1872.
PROVISIONAL SPECIFICATION left by the said Samuel Brooke at
the Office of the Commissioners of Patents, with his Petition, on
the 8th October 1872.
I, SAMUEL BROOKE, of the Firm of Samuel Brooke and Company, of
Brighouse, in the County of York, Card Makers, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN CARDING ENGINES,"
to be as follows:
This Invention consists in the construction and application of one or
more taking-off strippers or card rollers having a spiral strip or band of
emery interspersed or intervening at suitable distances apart in or between
rings of filleting or card clothing, for the purpose of grinding the cards

page_text: on the worker's breast swift and doffers whilst at ordinary work in
stripping the fibre therefrom.
The method of constructing such strippers or rollers is by first pre-
paring a narrow strip of card filleting, and winding it spirally upon a
roller of the same or any suitablo diameter, and introducing liquid glue
or other gummy substance and emery into or amongst the card teeth,
filling the interstices thereof full to the points of the teeth. Then while
the glue or other substanco is setting I separate the strip at its adjoining
sides, and then when fully set remove the same from the roller, and wind
it on the stripper roller alternately with the ordinary card filleting. Or
bands of a composition of india-rubber or gutta percha, with emery or
other similar substances, or materials possessing the quality of grinding
may be used for this purpose.
Another method of constructing the strippers aforesaid is to employ
spirally arranged strips of card cloth or clothing of increased thickness,
in which are "set" card teeth of steel. The additional thickness of the
cloth in which these teeth are set gives rigidity thereto, and the metal of
which they are made being harder than that employed for the ordinary
cards, the latter are ground by the spiral strips of steel cards arranged as
above described.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Samuel Brooke in the Great Seal Patent Office
on the 8th April 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
BROOKE, of the Firm of Samuel Brooke and Company, of Brighouse, in
the County of York, Card Makers, send greeting.
•
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighth day of October, in the
year of our Lord One thousand eight hundred and seventy-two, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Samuel Brooke, Her special

page_text: licence that I, the said Samuel Brooke, my executors, administrators,
and assigns, or such others as I, the said Samuel Brooke, my exe-
cutors, administrators, and assigns, should at any time agree with, and
no others, from time to time and in 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
CARDING ENGINES," upon the condition (amongst others) that I, the said
Samuel Brooke, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should par-
ticularly 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 Samuel Brooke, do hereby declare
the nature of my 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 Sheet of Drawings, that is to
say:
This Invention consists in the construction and application of one or
more taking-off strippers or card rollers having a spiral strip or band
of emery interspersed or intervening at suitable distances apart in or
between rings of filleting or card clothing, for the purpose of grinding
the cards on the worker's breast swift and doffers whilst at ordinary work
in stripping the fibre therefrom.
The method of constructing such strippers or rollers is by first pre-
paring a narrow strip of card filleting, and winding it spirally upon a
roller of the same or any suitable diameter, and introducing liquid glue
or other gummy substance and emery into or amongst the card teeth,
filling the interstices thereof full to the points of the teeth, then while
the glue or other substance is setting I separate the strip at its adjoining
sides, and then, when fully set, remove the same from the roller and
wind it on the stripper roller alternately with the ordinary card filleting.
Or bands of a composition of india-rubber or gutta percha, with emery
or other similar substances, or materials possessing the quality of grinding
may be used for this purpose.

Another method of constructing the strippers aforesaid is to employ
spirally arranged strips of card, cloth, or clothing of increased thickness,
in which are sct" card teeth of steel. The additional thickness of the
cloth in which these teeth are set gives rigidity thereto, and the metal of
which they are made being harder than that employed for the ordinary
cards, the latter are ground by the spiral strips of steel cards arranged as
ahove doserihod
Fig. 1 is an elevation of a card roller constructed according to the
first part of this my Invention. A is the stripper or card roller; B is
the strip of card filleting and emery prepared as herein-before explained,
which is wound spirally upon the roller alternately with the ordinary
card filleting C, the roller being thus covered or clothed with alternate
spiral strips of ordinary card filleting, and of others filled up with glue
or other gummy or adhesive substance and emery.
At Fig. 2 is shown a longitudinal section of a roller constructed
according to the second part of the said Invention, having spirally:
arranged strips of card clothing B of greater thickness of greater thick-
ness of cloth or other material in which the teeth are set, and these teethi
I make of steel. The additional thickness of the cloth in which these.
teeth are set, and the teeth being made of steel, a greater rigidity or
firmness is obtained in these teeth than those of ordinary card clothing.
It will now be readily seen that strippers or rollers constructed as
above described their teeth will be firmer and harder than the ordinary
cards used for the cylinders, or the swifts, breasts, doffers, or working
rollers of carding engines, so that by the application of the former to
carding engines the teeth of the latter will thereby be ground and a
sharpened.
Having thus described the nature of my said Invention, and shewn by
the accompanying Sheet of Drawings the manner in which the same is
performed or carried into practice, I would have it understood that I

page_text: claim the construction, application, and use of strippers or card rollers,
in manner herein described and shewn.
In witness whereof, I, the said Samuel Brooke, have hereunto set
my hand and seal, this Fifth day of April, in the year of our
Lord One thousand eight hundred and seventy-three.
