page_text: LETTERS PATENT to John Hall the younger, of Mount Pleasant, Wal-
mersley, near Bury, in the County of Lancaster, Spinner and Manu-
facturer for the Invention of "IMPROVEMENTS IN JACQUARD LOONS"
Sealed, the 10th June 1856, and, dated the 10th December 1855.
PROVISIONAL SPECIFICATION left by the said John Hall at the Office of
the Commissioners of Patents, with his Petition on the 10th December
1855.
I, JOHN HALL the younger, of Mount Pleasant, Walmersley, near Bury, in
the County of Lancaster, Spinner and Manufacturer, do hereby declare the
nature of the said. Invention, for "IMPROVEMENTS IN JACQUARD LOOMS" to be
as follows:-
My Invention relates to those kind of looms known as jacquard looms,.
and consists,, firstly, of working the box motion direct from the jacquard hook
by means of horizontal and vertical levers, so that as the jacquard hook acts
upon an horizontal lever it causes a vertical lever to work the shuttle box.
Secondly, of working, the picker direct from the jacquard hook by similar
means.
And, thirdly, of using a separate stop rod to each shuttle when more than
one shuttle is used..

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said John Hall in the Great Seal Patent Office on the 10th June
1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN HALL
the younger, of Mount Pleasant, Walmersley, near Bury, in the County of
Lancaster, Spinner and Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Royal
Letters Patent bearing date the Tenth day of December, in the year of
our Lord One thousand eight hundred and fifty-five, in the nineteenth year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said John Hall the younger, Her special licence that I, the said John
Hall the younger, my executors, administrators, and assigns, or such others as
I, the said John Hall the younger, my 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 "IMPROVE-
MENTS IN JACQUARD LOOMS," upon the condition (amongst others) that I, the said
John Hall the younger, by an instrument in writing under my hand and
seal, should particularly describe and ascertain the nature of the said Inven-
tion, 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 Royal Letters Patent.
NOW KNOW YE, that I, the said John Hall the younger, do hereby
declare the nature of the 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) :-
"
My Invention relates to those kind of looms known as "jacquard looms,"
and consists, firstly, of working the box motion direct from the jacquard hook
by means of horizontal and vertical levers, so that as the jacquard hook acts
upon an horizontal lever it causes a vertical lever to work the shuttle box.
Secondly, of working the picker direct from the jacquard hook by similar
means.
And, thirdly, of using a separate stop rod to each shuttle where more than
one shuttle is used, as described in my Provisional Specification; which third
part I now disclaim and omit in this my complete Specification, which
improvements in jacquard looms I accomplish by causing the jacquard hooks,

page_text: in conjunction with the cards used for forming the pattern in the manufacture:
of figured cloth, to be the first means of putting levers or pulleys into motion as'
a preparation, which may be afterwards acted upon by any of the well-known
methods of raising the shuttle or drop box where a series of shuttles are used.
The jacquard hooks are connected to levers or lifters which raise, lower, or:
move transversely certain inclines or wedges, which act upon a lever con-
nected with the drop box motions. When a star wheel is employed it is.
moved in conjunction with the cam wheel, thereby causing the indentations of
the said star wheel to be either in or out of gear of a stud or pin on a toothed
wheel, driven by another toothed wheel on the crank shaft of the loom. The
cam wheel connected to the star wheel acts upon a bowl or roller, attached to.
either a straight or cranked lever connected by a bar or rod to the drop box,
which is caused to rise and fall as the cam wheel is moved, according to the
pattern desired. I employ jacquard hooks in conjunction with cards to move'
the picker levers for driving the picker shaft.
These improvements will be clearly understood by reference to the
accompanying Sheet of Drawings, with the figures and letters of reference
thereon.
Fig. 1 is an end, and Fig. 2 a front elevation, of part of a loom in which
the wedges or inclines which move downwards are connected by levers to
jacquard hooks, shewing also how the shuttle box is acted upon; Fig. 3 is a
front elevation, representing another arrangement of levers; Fig. 4, a plan,
shewing the lever which is acted upon by the wedges or inclines; Fig. 5;
represents the wedges or inclines detached from the loom. Figs. 6 and 7
represent another arrangement in which the wedges or inclines move upwards;
and Fig. 8 represents a picker lever connected to a jacquard hook.
In Figs. 1 and 2, a represents the main frames of the loom; b, the jacquard
hooks, connected to the levers c, moving on their pivots or fulcrums d. To the
levers c are connected the rods e, having near their lower ends the wedges or
inclines g and h, which act upon the lever i. The crank shaft is represented
at k, upon which is the toothed wheel 7, driving another toothed wheel m,
having a stud or pin¸n, which fits the indentations in the star wheel o, causing
it to turn when both are in contact. With the star wheel o the cam wheel p
is connected by a boss, having a groove in which is placed the edge of the
lever i, the latter being moved to and fro by means of the wedges or inclines g
and h when they are acted upon by the levers c and the jacquard hooks b.
When a change of shuttle is required, the lever i moves the star and cam
wheel, causing the indentations to be in a line and in gear with the stud n as it

page_text: revolves, thereby giving motion as long as required to the star and cam wheels.
The latter presses against the roller q on the bent lever r, thereby giving
it motion, and also to the shuttle box s, by means of the connecting rod t. It
is evident that by employing either an extra cam wheel or one of a different
shape more shuttles can be used. One of the wedges or inclines also moves
the star wheel out of gear of the stud n, thereby allowing as much dwell as
desired, according to the cards or pattern. The springs u cause the return or
counter movement of the wedges or inclines.
In Fig. 3 the jacquard hooks are represented at a¹ attached to the levers or
lifters 6', connected to the balance levers c¹, moving on their pivots or fulcrums
d', the levers c¹ giving motion to the rods e¹ and wedges or inclines f, g, and h¹,
(shewn detached at Fig. 5); the said wedges operating upon a lever k¹, placing
it in a position to influence or be acted upon by any of the shuttle box motions.
The springs cause the return movement of the wedges. Although three
wedges or inclines are shewn, two or more wedges and shuttles may be
employed.
In Figs. 6 and 7 the wedges or inclines are represented in a reverse
position to those before described, and produce their effect by being pulled
upwards by levers or pulleys and chains or cords, one of which is shewn at m¹
connected to the shaft n', motion being given to it by means of the lever o'
and jacquard hook p¹.
Fig. 8 represents a picker lever connected to a jacquard hook, the said lever
moving on its fulcrum at q', and connected at r¹ to the picker shaft.
Having now fully described the nature and particulars of my said Invention,
and in what manner the same may be carried into practical effect, I desire it
to be distinctly understood that I do not confine myself to the exact details
herein set forth, as such may be varied or modified without departing from the
peculiar character of my Invention; but what I claim is,―
Firstly, the employment of jacquard hooks, in conjunction with the cards or
lags used in the manufacture of figured cloth, to be the means after the loom
is put in motion of giving action to levers or pullies as a preparation, which
may be afterwards acted upon by any of the well-known methods of raising the
shuttle or drop box where a series of shuttles are used.
Secondly, in the employment of wedges or inclines acting in any position
upon an arm or lever connected with shuttle or drop box motions.
Thirdly, the employment of jacquard hooks for working the picking
motion.
And, fourthly, the general arrangement for moving the star and cam wheels

page_text: in and out of gear by the inclines or wedges, as all such improvements are
herein described, and illustrated in the accompanying Sheet of Drawings.
In witness whereof, I, the said John Hall the younger, have hereunto
set my hand and seal, this Ninth day of June, One thousand eight
hundred and fifty-six.
JOHN HALL THE YOUNGER. (L.S.)
Signed, sealed, and delivered by the within-named
John Hall the younger, in the presence of
E. J. HUGHES, Patent Agent,
