Year: 1873

page_text: LETTERS PATENT to James Law and Samuel Law, of the Firm of
Samuel Law and Sons, of Cleckheaton, in the County of York,
Card Manufacturers, for the Invention of "IMPROVEMENTS IN CARDS
FOR CARDING WOOLLEN, COTTON, SILK, AND OTHER FIBRES, AND IN THE
MACHINERY OR APPARATUS TO BE EMPLOYED IN THE MANUFACTURE OF THE
WIRE FOR SUCH CARDS."
Scaled the 27th June 1873, and dated the 7th January 1873.
PROVISIONAL SPECIFICATION left by the said James Law and
Samuel Law at the Office of the Commissioners of Patents, with
their Petition, on the 7th January 1873.
We, JAMES LAW and SAMUEL LAW, of the Firm of Samuel Law and
Sons, of Cleckheaton, in the County of York, Card Manufacturers, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
CARDS FOR CARDING WOOLLEN, COTTON, SILK, AND OTHER FIBRES, AND IN THE
MACHINERY OR APPARATUS TO BE EMPLOYED IN THE MANUFACTURE OF THE WIRE
BOR SHOW CARDS "to be as follows:—
PROVISIONAL SPECIFICATION left by the said James Law and
Samuel Law at the Office of the Commissioners of Patents, with
their Petition, on the 7th January 1873.
We, JAMES LAW and SAMUEL LAW, of the Firm of Samuel Law and
Sons, of Cleckheaton, in the County of York, Card Manufacturers, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
CARDS FOR CARDING WOOLLEN, COTTON, SILK, AND OTHER FIBRES, AND IN THE
MACHINERY OR APPARATUS TO BE EMPLOYED IN THE MANUFACTURE OF THE WIRE
FOR SUCH CARDS ” to be as follows:—
"
This Invention consists,―
Firstly. In the application and use of wire in the manufacture of
card teeth shaped and compressed by the pressure of grooved rollers to
the various forms herein-after described, whereby additional strength is

page_text: imparted to the card teeth made from wire so condensed and formed,
which may be "set" in leather, india-rubber, or other material usually
employed for such purpose.
Secondly. The Invention relates to the means of adjusting the
grooves on the rollers relatively to each other, and for directing and
guiding the wires to and between the grooves of the said rollers.
The forms (on cross section) of wire we employ are plano-convex,
convex, or double convex, elliptical, semi-elliptical, oval or egg shaped,
semi-oval or semi-egg shaped, rhomb or rhombus shaped. These are the
forms we find give the best results, and are produced with equal facility
as the round or flat wires heretofore employed in the manufacture of
card teeth.
The grooved rollers are mounted on shafts or spindles, and work in
bearings or necks. Each end of each shaft is chased or screwed, and
provided with an adjusting nut, so that the shafts on which the grooved
rollers are mounted may be moved laterally in their bearings with great
nicety, so as to bring the grooves in each roller exactly opposite and
"true" with each other; and the nuts being screwed close to the
brasses or bearings will ensure the grooves being kept in proper relative
position to each other. A conical guide or instrument is connected to a
slide piece worked by means of an adjusting screw; through the centre
of this guide the wire to be rolled is passed, and by means of the
adjusting screw and an index marked on the slide piece or rail the wire
is set opposite to and guided between the groove required for giving to
such wire the compression and section or form desired. Or the shafts of
the said grooved rollers may be carried in centres having a screw adjust-
ment for setting the rollers and the grooves formed therein true with
each other.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Law and Samuel Law in the Great Seal
Patent Office on the 7th July 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JAMES
LAW and SAMUEL LAW, of the Firm of Samuel Law and Sons, of
Cleckheaton, in the County of York, Card Manufacturers, send
greeting.

Letters Patent, bearing date the Seventh day of January, in the
year of our Lord One thousand eight hundred and seventy-three; in.
the thirty-sixth year of Her reign, did, for Herself, Her heirs and.
successors, give and grant unto us, the said James Law and Samuel.
Law, Her special licence that we, the said James Law and Samuel,
Law, our executors, administrators, and assigns, or such others as
we, the said James Law and Samuel Law, our executors, adminis-
trators, 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 CARDS FOR
CARDING WOOLLEN, Cotton, Silk, and other Fibres, AND IN THE MACHINERY OR
APPARATUS TO BE EMPLOYED IN THE MANUFACTURE OF THE WIRE FOR SUCH CARDS,"
upon the condition (amongst others) that we, the said James Law and
Samuel Law, 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 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 James Law and Samuel Law,
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
Sheet of Drawings, that is to say :-
This Invention consists,―
-

page_text: The forms (on cross section) of wire we employ are plano-convex,
convex, or double convex, elliptical, semi-elliptical, oval or egg shaped,
semi-oval or semi-egg shaped, rhomb or rhombus shaped. These are
the forms we find give the best results, and are produced with equal
facility as the round or flat wires heretofore employed in the manu-
facture of card teeth.
The grooved rollers are mounted on shafts or spindles, and work
in bearings or necks. Each end of each shaft is chased or screwed,
and provided with an adjusting nut, so that the shafts on which the
grooved rollers are mounted may be moved laterally in their bearings
with great nicety, so as to bring the grooves in each roller exactly
opposite and "true" with each other; and the nuts being screwed close
to the brasses or bearings will ensure the grooves being kept in proper
relative position to each other. A conical guide or instrument is con-
nected to a slide piece worked by means of an adjusting screw; through
the centre of this guide the wire to be shaped is passed, and by means
of the adjusting screw and an index marked on the slide piece or rail the
wire is set opposite to and guided between the groove required for giving
to such wire the compression and section or form desired. Or the
shafts of the said grooved rollers may be carried in centres having a
screw adjustment for setting the rollers and the grooves formed therein
"true" with each other.

page_text: in their bearings with great nicety, so as to bring the grooves in each
roller exactly opposite each other. The adjusting nuts may be placed at
the extreme ends of the shafts if desired, though we find that the fore-
going arrangement is more convenient. A conical guide G (see Figs. 10
and 11) is connected to a slide piece H worked by means of an adjusting
screw J, through the centre of which the wire to be shaped is passed,
and by means of the adjusting screw and an index marked on the slide
piece or rail the wire is set opposite to and guided between the groove
required.
Having thus fully described the nature and particulars of this our
said Invention, we wish it to be understood that we do not claim the
whole of the parts herein mentioned; but what we do claim is,―
Firstly. The application and use of wire in the manufacture of card
teeth shaped and compressed by the pressure of grooved rollers to the
various forms shewn and described.
Secondly. The means of adjusting the grooves on the rollers relatively
to cach other, and for directing and guiding the wires to and between
the grooves of the said rollers as shewn and described.
In witness whereof, I, the said James Law for and on behalf of
myself and the said Samuel Law, have hereunto set my hand and
seal, this Fifth day of July, in the year of our Lord One
thousand eight hundred and seventy-three.
Signed, sealed, and delivered by
the within-named James Law,
in the presence of,
