Year: 1862

page_text: LETTERS PATENT to James Broadley, of Saltaire, in the County of York,
Overlooker to Messrs. Titus Salt, Sons, & Co., of the same Place,
Spinners and Manufacturers, for the Invention of "IMPROVEMENTS IN
"
Sealed the 11th November 1862, and dated the 17th May 1862.
PROVISIONAL SPECIFICATION left by the said James Broadley at the
Office of the Commissioners of Patents, with his Petition, on the 17th
May 1862.
I, JAMES BROADLEY, of Saltaire, in the County of York, Overlooker to
Messrs. Titus Salt, Sons, & Co., of the same Place, Spinners and Manufac-
turers, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MEANS OR APPARATUS EMPLOYED IN WEAVING," to be as follows:-
The improvements relate first to a combination of means in connection
with the jacquard apparatus for governing the times and order of motion of
shifting shuttle boxes of looms. I apply the jacquard barrel upon an axis
carried by a bar or rod operated directly by an eccentric of which such bar or
rod forms the rim. The eccentric is applied on the tappet or other suitable
shaft to give the desired up-and-down motion to the barrel, in order to its
being turned by a click or driver, and to its operating levers or rods, which,
by means of rods are connected to hooked levers adapted to act on one or the

page_text: other of two of the ends of a T- lever, the third end of which is by a double
hooked rod capable of operating the series of rotary shuttle boxes to move
them in either direction.
Also the improvements relate to means of arranging and operating parts
for producing gauze weaving, and changes from gauze to other weaving. The
pulley on the lever operating the heddle or harness motion is formed with two
or more parts or surfaces, either of which is adapted to be operated by cams
or tappets, and the pulley has two studs applied to its face on opposite sides
of its centre, one or other of which studs rests against a projection from a bar
carried by the lever already referred to, and which bar is capable of being
lifted by jacquard or pattern surface to release one or the other of the pins
so as to effect a change from gauze to other weaving. There is a double slay
or comb through which the warps pass such slay or comb having a long dent
and a short dent. The short dent is placed in front or between the space of
the long dent. A slay or comb moves the reverse way to the larger slay or
comb and has an endway motion given to it causing the warp thread to move
up one side of the other blade and then up the other side as required. The
axes of the levers carrying these slays or combs are connected together by a
pair of toothed wheels.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Broadley in the Great Seal Patent Office on the
14th November 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
BROADLEY, of Saltaire, in the County of York, Overlooker to Messrs. Titus
Salt, Sons, & Co., of the same Place, Spinners and Manufacturers, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of May, in the year of our Lord One
thousand eight hundred and sixty-two, in the twenty-fifth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
James Broadley, Her special licence that I, the said James Broadley, my
executors, administrators, and assigns, or such others as I, the said James
Broadley, 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

page_text: vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN MEANS OR
APPARATUS EMPLOYED IN WEAVING," upon the condition (amongst others) that
I, the said James Broadley, 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said James Broadley, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, thereof, that is to say:-
The improvements relate, first to a combination of means in connection
with the jacquard apparatus for governing the times and order of motion of
shifting shuttle boxes of looms. I apply the jacquard barrel upon an axis
carried by a bar or rod operated directly by an eccentric, of which such bar or
rod forms the rim. The eccentric is applied on the tappet or other suitable
shaft to give the desired up-and-down motion to the barrel in order to its
being turned by a click or driver, and to its operating levers or rods, which by
means of rods are connected to hooked levers adapted to act on one or the
other of two of the ends of a T lever, the third end of which is by a double
hooked rod capable of operating the series of rotary shuttle boxes to move
them in either direction.
Secondly, the improvements relate to means of arranging and operating
parts for producing gauze weaving and changes from gauze to other weaving.
The pulley on the lever operating the heddle or harness motion is formed
with two or more parts or surfaces, either of which is adapted to be operated
by cams or tappets, and the pulley has two studs applied to its face on opposite
sides of its centre, one or other of which studs rests against a projection from
a bar carried by the lever already referred to, and which bar is capable of
being lifted by jacquard or pattern surface to release one or the other of the
pins so as to effect a change from gauze to other weaving. There is a double
slay or comb through which the warps pass, such slay or comb having a long
dent and a short dent. The short dent is placed in front or between the
space of the long dent. A slay or comb moves the reverse way to the larger
slay or comb, and has an endway motion given to it causing the warp thread
to move up one side of the other blade, and then up the other side as required.

page_text: The axes of the levers carrying these slays or combs are connected together
by a pair of toothed wheels. But that the nature of the improvements and
the means which I adopt in carrying the same into effect, may be better
understood, I will proceed by the aid of the accompanying Drawing more
fully to describe the same.
DESCRIPTION OF THE DRAWING.
Figure 1 shows parts of an end view of a loom with the improvements
applied to it; Figures 2 and 3 show parts separately.
a is the framing; b, the crank shaft; c, the tappet shaft; d, one of the
swords of the batten, having a projecting support or framing d to carry the
axis e¹ of the shuttle box' e. Upon the tappet shaft c' is 'affixed the eccentric f,
which is embraced by the rim formed by the lower end of the bar g, the upper
end of which carries, by a stud g¹, the jacquard cylinder i, and is also formed
with a neck g' adapted to slide in a hole in the stationary guide h. By these
means a simple up-and-down motion is given to the jacquard cylinder i, and
in such motion a step-by-step rotary motion is imparted to the cylinder i, by
the ratchet wheel thercon being operated by the click or driver k, to bring the
respective cards carried thereby to act upon the studs ¹ projecting from the
under side of the levers j,j, and lift those levers in the order required. The
levers j, j, turn upon an axis 7, and at their outer ends are, by the links 1, 2,
connected respectively to the levers m, m, which turn upon a fixed stud m
projecting from the franiing a, whilst at its outer end each lever m is formed
with a hook m adapted, when either of them is lifted into position by the
lifting of its lever m, of catching on to one or other of the studs n' on the
T lever n, which turns upon a stud n² carried by the framing d, and also
carries, by a stud n³, the catch and driver n', which, by its hooks no, n", acting
on the studs e projecting from a plate carried by the series of shuttle boxes,
is capable of pulling or driving the shuttle box e partly round for changes of
shuttle.
I will now describe the second part of the improvements. o is a lever
which at one end turns on the fixed stud ol, whilst its other end is, by an
adjustable link o, connected to an arm o from the axis o, and there are affixed
on this axis opinions o³ (represented by dotted lines), the teeth of which take
into the teeth of pinions of affixed on the shaft or axis 07. The axes o and o
have affixed on them respectively arms o8 and 0° for operating the parts of the
warp. One part of the warp is conducted through the eyes p¹ of the shor
dents of the slay or coub p, which is also provided with other long dents p

page_text: the dents p being intermediate of the dents p³. The axis o, by its arms o³,
operates the slay or comb p, whilst the arms of from the axis o7, by means of
the links o, give an up-and-down motion to the slay or comb q, through
which is conducted the other portion of the warp. By these means the slay
or comb p and the slay or comb 7 will be constantly caused to move in opposite
directions, causing the respective portions of the warp carried by them to move
in opposite directions, forming sheds for the passage of the shuttle. Upon the
lever o is affixed a stud carrying the pulley or roller r, which is acted upon by
the cam or tappet s, and this pulley or roller r is formed in two, or it may be
in more parts r¹, 7, either of which may be brought into contact with, so as to
be operated by the cam or tappet s, and this change of relation of the pulley
or roller r to the cam or tappet s is effected in the following manner:-Upon
the stud j³ is also carried one end of a lever, similar to the levers j, j, with a
stud in position to be acted upon by the cards carried round by the cylinder i.
This lever is, by a rod t, connected to the lever t¹, which at one end turns upon
a stud projecting from the lever o, and at the other is formed with a pro-
jection to rest against one or other of the studs or carried by the pulley
or roller r. When the projection is resting against the stud the surface r¹
of the pulley or roller r will be acted upon by the cam or tappet s and sheds
will be formed in the warp for the production of plain weaving. But when it
is desired to change from plain weaving to cross weaving, then the jacquard
will operate to lift the lever t¹ so as to admit of the pulley or roller r making
partial rotation, when the stud will rest against the projection &, and the
surface of the pulley or roller r will rest on the cam or tappet s, and the
dents p will be raised only sufficiently high to bring their eyes p', with the
warps carried thereby, just above, being in a line with the other portion of the
warps carried by the slay or comb q, which is also capable of a slight endway
motion, so that when the two sets of warps are in the relative position last
referred to those carried by the dents p³ may be carried over those carried by
the slay or comb q to the right or to the left hand, and be carried down
between those of the slay or comb q alternately on opposite sides of them.
a
Figure 4 shows a modification of the arrangement of parts shown by
Figure 3 with the short dents p² partly between the long dents p³.
Having thus described the said Invention, and the means I adopt in carry-
ing the same into effect, I would have it understood that I do not confine
myself to the precise details shown, nor do I claim the mechanical parts sepa-
rately considered, but what I do claim is,
First, the adaptation or combination of means, in connection with jacquard

page_text: apparatus, for governing the times and order of motion of shifting shuttle
boxes, substantially as explained.
Secondly, I claim the adaptation or combination of means for producing
changes in the order of weaving, substantially as explained in respect of the
second head of Invention.
In witness whereof, I, the said James Broadley, have hereunto set my
band and seal, this Tenth day of November, in the year of our Lord
One thousand eight hundred and sixty-two.
JAMES BROADLEY. (L.S.)
