IMPROVEMENTS IN JACQUARD APPARATUS APPLICABLE TO POWER LOOMS
Year: 1859

page_text: LETTERS PATENT to Gaylard Hadwen, of Audenshaw, in the County of
Lancaster, and John Wadsworth, of Droylsden, in the said County, for
the Invention of "IMPROVEMENTS IN JACQUARD APPARATUS APPLICABLE TO
POWER LOOMS."
Sealed the 2nd August 1859, and dated the 12th February 1859.
TROVISIONAL SPECIFICATION left by the said Gaylard Hadwen and Johni
Wadsworth at the Office of the Commissioners of Patents, with their
Petition, on the 12th February 1859.
We, GAYLARD HADWEN, of Audenshaw, in the County o' Lancaster, and
JOHN WADSWORTII, of Droylsden, in the said County, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN JACQUARD APPARATUS
APPLICABLE TO POWER LOOMS," to be as follows:-
Instead of employing one card cylinder and one set of hooks and needles,
as hitherto adopted, we employ two card cylinders and two sets of hooks and
needles, and cause each cylinder to work half the number of the cards of the
pattern, by which means we are enabled to work the loom at a greater specil,
and consequently obtain a greater result, and economize the wear and tear of
the cards. The cylinders are worked to and fro by levers put in motion by a
crank or cranks fixed to the tappet wheel or connected with the tappet shaft,
and the shed is formed by giving motion to lovers by means of either the same
cranks or other cranks placed either upon the tappet wheel or tappet shaft;
but the aforesaid simple motions may be communicated from any other working
part of the loomi.

by the said Gaylard Hadwen and John Wadsworth in the Great Seal
Patent Office on the 11th August 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GAYLARD
ILADWEN, of Audenshaw, in the County of Lancaster, and JOHN WADSWORTH,
of Droylsden, in the said County, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelfth day of February, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-second year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said Gaylard Hadwen and John Wadsworth, Her special licenco
that we, the said Gaylard Hadwen and John Wadsworth, our executors,
administrators, and assigns, or such others as we, the said Gaylard Hadwen
and John Wadsworth, 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 JACQUARD APPARATUS APPLICABLE TO POWER LOOMS," upon the
condition (amongst others) that we, the said Gaylard Hadwen and John
Wadsworth, by an instrument in writing under our hands and seals, or
under the hand and seal of one of us, 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 Gaylard Iladwen and John Wadsworth,
do hereby declare the nature of the said Juvention, and the mauner in whicli
the same is to be performed, to be particularly described and ascertained
in and by the following statement (that is to say):-
Our Invention consists in employing two card cylinders and two sets of
hooks and needles, two needle boards and two spring boxes instead of onó
card cylinder, one set of hooks and needles and one needle board, and one
spring box, as hitherto adopted, both sets of hooks and needles being united
to one harness by means of double-neck bands; and we thus obtain all the
advantages hitherto attained by two machines.
We cause each cylinder to work half the number of cards of the pattern;
and are thereby enabled to work the loom at a greater speed, and conse-

page_text: forth, as such may be varied or modified.without departing from the principle
thereof; but we claim as our Invention, and which to the best of our know-
ledge and belief has not been hitherto used within the realm, the employment
to jacquard apparatus for power looms of two card cylinders for working two
sets of cards of an equal or nearly equal number in connection with two sets
of hooks and needles, two needle boards, and two spring boxes, as such
improvements are herein described and illustrated in the accompanying Sheet
of Drawings.
In witness whereof, I, the said Gaylard Hadwen, for and on behalf of
myself and the said John Wadsworth, have hereunto set my hand
and seal, this Ninth day of August, in the year of our Lord One
thousand eight hundred and fifty-nine.
GAYLARD HADWEN. (L.s.)
Signed, sealed, and delivered by the within-
named Gaylard Hadwen, in the presence of
E. J. HUGHES,
Patent Agent,
Manchester.

cards. The cylinders are worked to and fro, and the shed formed by means
of levers connected by rods and cranks on the tappet shaft.
These improvements will be clearly understood by referring to the letters
and figures on the accompanying Sheet of Drawings, in which Figure 1
represents a front elevation, and Figure 2 a transverse elevation of the framing
and other parts of a loom with our improvements attached; Figure 3, a
vertical section of part of the jacquard apparatus; Figure 4, a plan of the
upper lifter; and Figure 5, a plan of the lower lifter.
The frame of the jacquard apparatus is shewn at a, having at each end the
guide rods for guiding the lifters c and d, to each of which a number of
knives are attached for raising. the two sets of hooks. The up and down
motion is given to the upper series of knives and lifters by connecting the
latter by the link e to one end of the lever f working on the pin. or fulcrum g
fixed to the standard h, which is bolted to the beam i. The lower series of
knives and lifter are moved up and down by the lever working on a pin
fixed to the standard h, motion being given to both levers by connecting them
with the rods m and n to a long crank pin o, forming part of a double crank
fixed to the tappet shaft p, which crank is shewn at the bottom stroke, and
acts upon the upper lever so as to place the lifter in its highest position and
the lower lifter in its lowest position. As the crank revolves the lifters
gradually approach each other until arrived at the other extreme of the stroke,
as shown by the dotted lines.
In consequence of employing two sets of hooks and needles, we require two
needle boards, two spring boxes, and also two card cylinders, and two sets
of cards.
The card cylinders work on pins or centres in the swings q and 1', suspended
on centres attached to the framing a. The two swings are linked together by
the beams or rods s, so that they move together alternately inwards and outwards
as required; and in order to give motion to the swings, the swing is connected
by the rod t to one arm of the lever u fixed to the shaft vthe other arm
being connected by the rod w to the crank a, forming part of the double crank
fixed to the tappet shaft.
The card cylinders may be moved to and fro and the shed formed by cams
or tappets, having motion communicated to them by any suitable working
part of the loom.
Having thus fully described the nature of our said Invention, and the
manner in which the same is to be performed, we desire it to be distinctly
understood that we do not confine ourselves to the precise details herein set
