page_text: LETTERS PATENT to George Pigott, of the Town and County of the Town
of Nottingham, Lace Maker, for the Invention of "IMPROVEMENTS IN
Sealed the 10th September 1858, and dated the 13th March 1858.
PROVISIONAL SPECIFICATION left by the said George Pigott at the
Office of the Commissioners of Patents, with his Petition, on the 13th
March 1858.
I, GEORGE PIGOTT, of the Town and County of the Town of Nottingham,
Lace Maker, do hereby declare the nature of the said Invention for "IM-
PROVEMENTS IN JACQUARD MACHINERY FOR FIGURING LACE AND OTHER FABRICS,"
to bo as follows:-
My Invention consists in improvements in jacquard machinery for figuring
lace and other fabrics, and is as follows: -
I employ apparatus to move the top and bottom bars used in lace and other
machines, without using what is called a "Manchester top." The card
cylinders hayo only an up-and-down motion, which places the droppers where
required. The cams which give the requisite movements to the top and
bottom driving bars are placed on the same shaft as the cams which drive the

page_text: card cylinders, or they may be placed on a second shaft below, as found most
convenient, without the use of strings to the droppers, or a "Manchester top"
to move the said strings.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Pigott in the Great Seal Patent Office on the 13th
September 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
PIGOTT, of the Town and County of the Town of Nottingham, Lace Maker,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of March, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said George Pigott, Her special licence that I, the said George Pigott,
my executors, administrators, and assigns, or such others as I, the said
George Pigott, 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 "IMPROVEMENTS
IN JACQUARD MACHINERY FOR FIGURING LACE AND OTHER FABRICS,"
upon the
condition (amongst others) that I, the said George Pigott, my executors
or administrators, by an instrument in writing under my, 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 I, the said George Pigott, do hereby declare the
nature of my said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following state-
ment thereof, reference being had to the Drawings hereunto annexed, that is to
say:
My Invention consists in improvements in jacquard machinery for figuring
lace and other fabrics, and is as follows:-
I employ apparatus to move the top and bottom bars used in lace and other

page_text: machines, without using what is called a "Manchester top." The card
cylinders have only an up-and-down motion, which places the droppers where
required. The cams which give the requisite movements to the top and
bottom driving bars are placed on the same shaft as the cams which drive
the card cylinders, or they may be placed on a second shaft below, as found
most convenient, without the use of strings to the droppers, or a "Manchester
ton" to move the soil strings
Sheet 1.-Figure 1 represents a side view of a complete jacquard standing
at the right-hand end of a lace or other machine; Figure 2 is a side view;
and Figure 3, a front view of the castings and frame carrying the driving
blades and slides for the bottom bars.
Sheet 2. Figure 4 represents a left-hand end viow of the complete machine;
Figure 5 is a right-hand end view of the same, shewing the sley carrying the
top bar slides and tho cylinders which lift the droppers to the same; Figure
6 is a bottom bar, jack, or slide.
Sheet 3. Figure 7 is the cam which gives the requisite movements to the
driving blades and frame p'; Figure 8 is the cam for the driving blades and
frame p; Figure 9 is the cam which moves the cylinders and lifters to the
bottom bar slides; Figures 10 and 11 are the cams which move the driving
blades and slides to the top bars; Figure 12 is the cam which moves the
cylinders and lifters to the top bar slides.
Sheet 4. Figure 13 is a sectional side view of a combination of sleys,
slides, droppers, and lifters. When one cylinder is preferred to be used instead
of two, it makes one movement in the time the machine makes two. Figure
14 is a sectional side view of another combination of sleys, slides, droppers,
and lifters. In this combination, when one cylinder is used it makes a move-
ment for every movement of the machine.
Sheot 5. Figure 15 represents a right-hand end view of Figures 13 and
14; Figure 16 represents the cam which gives the requisite movement to the
cylinder which moves the lifters, and raises and shogs the lifting sley t;
Figure 17 represents another form of slide and sley.
The whole of the Figures being lettered and numbered to correspond, the
following description will apply to all.
a, a, Figure 1, represent the castings which support the shafts carrying the
requisite cams, levers, and other parts of the machine; this machine is got
out to what is called in the trade the "Manchester gauge," for 180 bottom

page_text: bars and 60 top bars; but it can be made to any gauge and with any number
of bars required. 6 represents one end of a short shaft having a bevel wheel
h
keyed on one end, gearing into a wheel c on the shaft c¹, supported
by brackets at each side of the frame; the other end of the shaft b has a wheel
on it which gears into a wheel on the driving shaft of the lace or other
machine. There is a cogged wheel C' at the other side of the machine on the
shaft c', which gears into a larger wheel C on the cam shaft g; d is a shaft
having a rocking lever e keyed on each end; near the end of each lever e is a
pin, upon which the end of a lever works, the other end working upon a
similar pin, projecting from the ends of the cylinders f and f'; these cylinders
are alternately raised and lowered by the slotted lever e¹ connected to a lever
and two trucks, which are moved by the cylinder cam e² on the shaft 9.
and h are two cams which move the slides carrying the driving blades; the
cam h moves the slides and blade h', and the cam h moves the slides and blade
h; to each of the driving blades are screwed brackets which carry a sley i,
each having 'horizontal and perpendicular wires, the perpendicular wires form-
ing the gauge of the sley. j are the hooked tails of the droppers ¹, which lie
upon the horizontal wires in the sleys i. are lifters, one to each dropper,
round at their lower ends, and flat the rest of their length the upper ends pass
through a sley, and the lower ends through a sley . On the pins in the
lifters the droppers rest, and are lifted up each time the cylinder riscs, until
the tops of the droppers are of such a height that the driving blades h' and ³,
moved by the cams h and he belonging to each set, may catch fast hold of
them, and clamp or jam them up against the upper portion of the top bar slide
1, thereby shogging the top bar slide, and with it the bar, the number of gates
required, and the number the droppers represent. Thus, one cylinder raises
and the other lowers alternately one set of droppers, according to the perforation
in the cards on the cylinders; each cylinder upon its descent is racked
round, by the clawker m hooking on to one of four pins, whereby a fresh card
is presented to each set of lifters every time the cylinders rise. n is a lever
held close to the rack pins at the end of each cylinder by a spring hooked on
to a pin in the casting a; the clawker m and lever n are also held together
by another spring. Thus the slide 7 is held up by the driving blade, and the
whole of the droppers which are lifted by the cylinder at the right hand when
that cylinder has fallen and the left-hand one has risen. If the same number
of droppers has been lifted, the slide will not have moved; but if some of the
droppers have been left down the slide will shog the number of gates the
droppers left down represent, until all the droppers being left down, the slides

page_text: Zand bars belonging to them will be down on what is called the dead stop or
starting point. Thus, whatever number of droppers are raised by the card,
are sure to be caught by the driver, and those that are not raised do not in any
way interfere with the working of the others. The six droppers shown move
the bars any number of gates from 1 to 47; a greater number of droppers
may be used without the driving blades having a greater throw given them,
and whatever number are used they will be perfectly free and independent of
each other.
If it is preferred to drive the slide from the under side, instead of at the side
or at the top, as shewn, the slide and sley represented at Figure 17, Sheet 5,
are used in addition, the sley catching the heads of the droppers and holding
them steady; in this case the driving blades will be placed underneath the
slides instead of above.
In the plan, Figure 1, the sides of the slides form boxes for the heads of
the droppers and hold them steady.
The above is a description of the whole of the apparatus required to move
the top bars when two cylinders are used, as shewn at Figure 1, each cylinder
moving up with a fresh card every other motion of the machine.
The following is a description of the apparatus which moves the bottom
bars: On the shaft e¹ are placed the cams shewn in Figures 7 and 8, Sheet 3,
which move the 4 levers o on the shaft o', two of which levers o aro
connected by short links to the driving frame p, and the other two to the
driving frame p; these frames both slide on shafts p, which are held fast by
set screws in bosses screwed to the castings a', resting on brackets a³, screwed
to the main castings a of the machine. The lifters are similar to those
before described, and are supported by sleys k¹ and ; q are levers on the
shaft o', moved by the cams, shown in Figure 9, Sheet 3; the other ends of the
levers are connected by short links to the pin ends of the cylinder 1; s, s, are
the slides, on one side of which the droppers S¹ and S2, work on pins, as shown
in Figure 6. The droppers S and S have the following movements :--The
cam, Figure 9, having moved the cylinder nearly up to its highest point, the
lifters, if the card is a blank, will lift the dropper S' sufficiently high for the
catch below the slide to rise above the bottom of the slide, to allow the driving
blade frame pl to pass up without moving the slide p, and then come down on
the dead stop; the cylinder then rises its full height, thereby causing the
dropper S to lift the dropper S clear of the bottom of the slide, so that as
the frame p goes up, the slide does not move during either lifts of the cylinder;
but if the card is punched, the lifter will not lift either of the droppers S¹ and

page_text: S, so that as the frame p¹ goes up, it will drive the slide up, and hold it there
until goes up, and holds it while p¹ comes down again for another card, to
make a fresh selection.
The above describes the whole of the movements in the perfect machine, as
shewn in Figure 1.
Figure 13, Sheet 4.-The movements of the combination represented in this
Figure are as follows:-Instead of two cylinders only one is used, twice the
width of those above described; there are the same number of droppers, and
twice the number of lifters; there is also a sley frame t, with as many fixed
lifters in it, and half the number of droppers; this frame is free to rise and
fall in four slide boxes , shewn in Figure 15; it is also free to shog to the
left and right a certain distance, which shogging is performed by means of a
lever, having one forked end working upon the end of the arm v, shewn in
Figure 15; the other end of the lever carries a truck, which runs upon the
cam, Figure 16, which is put in tho place of the cam, Figure 12, Sheet 3;
there are also two sleys for the tails of the droppers, in the place of the sloys
i, shown in Figure 1. A lever c, similar to that which moves the two cylin-
ders in Figure 1, here raises the double cylinnder until the lifters have
placed the droppers j¹ in front of the driving blade ; at the same time they lift
the other droppers up a short space, to allow the sley frame to shog and
place the pins in the lifters k³, under those droppers which are selected, the
droppers not selected remaining under the pins; the lever e then raises the
sley frame, and lifts the selected droppers in front of the driving blade h',
which blade embraces them and drives them up, the first droppers being re-
leased when a fresh selection is made; the droppers to the blade h¹ in falling
do not fall lower than upon the cross wires w, on which they rest until a fresh
selection; the cylinder making a selection during two motions of the machine.
Figure 14. The several parts in this combination correspond with the last
described, the movements being the same, except that the cylinder rises at
every motion of the machine, places the selected droppers in front of the blade
h³, and raises corresponding droppers for the sley frame, to lift up in front of
the blade h, thereby holding the slides in the position in which the driving
blade s has placed them. The movements are then repeated.
In the several combinations above described, the loose droppers are worked
without the assistance of a "Manchester top" and strings, and in a much
safer manner.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim, the several com-

page_text: binations of parts herein-before described, and represented in the Drawings
hereunto annexed, consisting of,-
First, the droppers and sleys for the tails of the droppers represented in
Figure 1, Sheet 1.
Secondly, tho bar, slide, and droppers represented in Figure 6, Sheet 2,
together with the manner of working the same.
Thirdly, the combination of parts represented in Figures 13, 14, and 15.
Fourthly, the slide and sleys for working loose droppers represented in
Figure 17, Sheet 5.
In witness whereof, I, the said George Pigott, have hercunto set my
hand and seal, this Tenth day of September, One thousand eight hundred
and fifty-eight.
