IMPROVE- MENTS IN JACQUARD AND INDEXING MACHINES
Year: 1865

page_text: LETTERS PATENT to Joseph Wadsworth, of Macclesfield, in the County
of Chester, Henry Dusset, and James McMurdo, of the City of
Manchester, in the County of Lancaster, for the Invention of "IMPROVE-
Sealed the 31st October 1865, and dated the 5th May 1865.
PROVISIONAL SPECIFICATION left by the said Joseph Wadsworth, Henry
Dusset, and James McMurdo at the Office of the Commissioners of
Patents, with their Petition, on the 5th May 1865.
We, JOSEPH WADSWORTH, of Macclesfield, in the County of Chester, HENRY
DUSSET, and JAMES MCMURDO, of the City of Manchester, in the County of
Lancaster, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN JACQUARD AND INDEXING MACHINES," to be as follows:-
This Invention consists in an improved arrangement of hooks and needles
for the purpose of dispensing with the spring box and springs of jacquard
machines, and also with one set of needles in the double-action machine.
The hooks are guided at the bottom in the ordinary bottom plate, and at
the top in strips of wood or metal, each strip serving for a row of hooks.
Between the bottom plate and strips there are two griffs for raising the hooks,
and one needle acts upon two hooks, so that when one end of the needle
is pressed by a blank in the card, one hook is pushed out of the way of its
corresponding griff without interfering with the other hook, and a similar
effect takes place when the other end of the needle is pressed by another
blank, the hooks returning to their original positions by their own elasticity.
In the single-action machine there are as many needles as hooks, but the

page_text: spring box and springs are dispensed with by the elasticity of the hooks, and
similar hooks and needles can be applied to indexing machines employed for
working a number of shafts or healds.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Wadsworth, Henry Dusset, and James McMurdo
in the Great Seal Patent Office on the 4th November 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOSEPH
WADSWORTH, of Macclesfield, in the County of Chester, HENRY DUSSET,
and JAMES MCMURDO, of the City of Manchester, in the County of Lancaster,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of May, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Joseph Wadsworth, Henry Dusset, and James McMurdo, Her special
license that we, the said Joseph Wadsworth, Henry Dusset, and James
MoMurdo, our executors, administrators, and assigns, or such others as we,
the said Joseph Wadsworth, Henry Dusset, and James McMurdo, our execu-
tors, 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 AND INDEXING
MACHINES," upon the condition (amongst others) that we, the said Joseph
Wadsworth, Henry Dusset, and James McMurdo, our executors or admi-
nistrators, by an instrument in writing under our, or their, or one of our
or 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 Joseph Wadsworth, Henry Dusset,
and James M Murdo, 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 (that is to
say):-

page_text: This Invention consists in an improved arrangement of hooks and needles
for the purpose of dispensing with the spring box and springs of jacquard
machines, and also with one set of needles in the double-action machine.
The hooks are guided at the bottom in the ordinary bottom plate, and at
the top in strips of wood or metal, each strip serving for a row of hooks.
Between the bottom plate and strips there are two griffs for raising the hooks,
and one needle acts upon two hooks, so that when the end of the needle
is pressed by a blank in the card, one hook is pushed out of the way of its
corresponding griff without interfering with the other hook, and a similar
effect takes place when the other end of the needle is pressed by another
blank, the hooks returning to their original positions by their own elasticity.
In the single-action machine there are as many needles as hooks, but the
spring box and springs are dispensed with by the elasticity of the hooks, and
similar hooks and needles can be applied to indexing machines employed for
working a number of shafts or healds.
This Invention will be clearly understood by referring to the figures and
letters on the accompanying two Sheets of Drawings, in which Fig. 1, Sheet 1,
is a sectional elevation of a jacquard apparatus. Figs. 2 and 3 shew the
mode of working two hooks with one needle, and Figs. 4 and 5 views of
the strips of wood for holding the hooks at the top. Fig. 6, Sheet 2, is a
front elevation, and Fig. 7 a plan of an improvement as applied to indexing
machines.
The hooks are guided at the bottom in the ordinary bottom plate a,
and at the top in strips of wood or metal b, shewn full size in Figs. 4 and 5,
each strip serving for row of hooks c. Between the bottom plate and
strips there are two griffs d, e, for raising the hooks and one needle f, Figs. 2
and 3, acts upon two hooks c, so that when the end of the needle is pressed
by a blank in the card one hole is pushed out of the way of its corresponding
griff, as shewn by the dotted lines in Figs. 2 and 3, without interfering with
the other hook, and a similar effect takes place when the other end of the
needle is pressed by another blank, the hooks returning to their original
positions by their own elasticity.
In the single-action machine there are as many needles as hooks; but the
spring box and springs are dispensed with by the elasticity of the hooks.
Figs. 6 and 7 shew our improvements as applied to indexing machines.
We make the machine double-acting, and place a card cylinder a on each
side. The needles b slide in the needle boards or frames c, each needle
working four hooks d, e, f, g, by means of the three eyes h, i, k. The eyes h, i,
move the two hooks d, e, and the eye k moves the two hooks f, g, the hooks

page_text: being held in ordinary bottom plates 1. When a needle is moved by a blank
in the card m, the hooks d, g, are placed on and the hooks e, f, pushed off the
griffs or knives n; or when a needle is moved by a blank in the card o on
the other side, the hooks e, f, are placed on and the hooks d, g, pushed off
the griffs or knives n. By this arrangement of needles and hooks we are
enabled to dispense with half the number of needles usually employed. We
also shew an arrangement for working four patterns with one set of needles..
To the needle boards c we attach levers p connected to other levers 9 fixed on
the ends of the shaft r; at the middle of the shaft is fixed the lever s, having
connected to it the lever t, in which are four holes u. When it is required
to change the pattern the lever t is moved backwards or forwards,, which
gives motion to the shaft r, levers p, q, and raises or lowers the needle boards c,.
placing the needles opposite the desired holes or pattern v in the cylinder a,
Fig. 7, the needles and boards being held in position by a pin being put
through one of the holes in the lever t into a corresponding hole in the
frame.
Having now described the nature and particulars of our said Invention, and
the manner in which the same is to be performed, we desire it to be understood
that we claim,-
First, in jacquard machines, the arrangement of 'hooks and needles,
and the mode of holding the hooks at the top, as shewn in the Drawings,
Sheet 1.
Secondly, the arrangement of hooks and needles; also the double-action
motion in indexing machines, as shewn in the Drawings, Sheet 2.
In witness whereof, I, the said Henry Dusset, for and on behalf of
myself and the said Joseph Wadsworth and James McMurdo, have
hereunto set my hand and seal, this Third day of November, in the
year of our Lord One thousand eight hundred and sixty-five.
Signed, sealed, and delivered by the
within-named Henry Dusset in
the presence of
E. J. HUGHES,
Patent Agent,
Manchester.
