Year: 1843

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MOSES
POOLE, of Lincoln's Inn, in the County of Middlesex, Gentleman, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Eleventh day of April, in the sixth year of Her reign, did, for
Herself, Her heirs and successors, give and grant unto me, the said Moses
Poole, Her especial licence, full power, sole privilege and authority, that
I, the said Moses Poole, my exors, admors, and assigns, or such others as
I, the said Moses Poole, my exors, admors, or assigns, should at any time
agree with, and no others, from time to time and at all times during the term
of years therein expressed, should and lawfully might make, use, exercise
and vend, within England, Wales, and the Town of Berwick-upon-Tweed,
the Invention of "IMPROVEMENTS IN THE MANUFACTURE OF ORNAMENTED LACE OR
NET," communicated to me from abroad; in which said Letters Patent is
contained a proviso, that I, the said Moses Poole, shall cause a particular
description of the nature of the said Invention, and in what manner the same
is to be performed, to be inrolled in Her said Majesty's High Court of
Chancery within six calendar months next and immediately after the date of
the said in part recited Letters Patent, as in and by the same, reference being
thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Moses Poole, do hereby declare that the nature of the said Invention, com-
municated to me from abroad, and the manner in which the same is to be

page_text: performed, are fully described and ascertained in and by the following state-
ment thereof, reference being had to the Drawings hereunto annexed, and to
the figures and letters marked thereon, that is to say:-
-The-Invention relates, first, to a mode of manufacturing-ornamented lace or
net where two or more warp threads are used to each bobbin thread. It is
well known that within these last few years ornamented lace, consisting of lace
with portions of cloth work, has been extensively manufactured by using two
or more warp threads to each bobbin thread, and Letters Patent were granted
to Mr. William Crofts, of Nottingham, for making the same, and in producing
the tops and bottoms of the meshes of the lace or net, the crossings of each
top or bottom of a mesh has been accomplished by means of only one of the
bobbin threads crossing over from pillar to pillar, generally twice from the
warp threads with which it has been working (to form a pillar), and linking
itself around one of the warp threads of a neighbouring pillar, the other bobbin
thread continuing to work with its warp threads whilst such crossing has been
made by the one bobbin thread, the crossing at the top and bottom of each mesh
being generally formed of four thicknesses of such one bobbin thread. By this
means of working, although very beautiful descriptions of ornamented lace or
net have been manufactured, there is an inequality of the work in the pillars
of each mesh, and at the same time the crossings constituting the tops and
bottoms of the meshes appear thick and spot-like, and are not in character with
the pillars of the meshes. Now, by the first improvement in the manufacture
of this description of ornamented net or lace, the crossings constituting the
tops and bottoms of the meshes will still consist each of four thicknesses of th
bobbin threads, but in place of the same being all from one bobbin thread,
passing from and to its warp threads or pillar to link in twice with the
neighbouring warp threads, the two bobbin threads of the two pillars of each
mesh will cross from their respective warp threads or pillars, and link with the
neighbouring pillars, and return to the pillar from which they respectively
departed when commencing a crossing, by which means the crossings will be
made more compact and in character with the pillars of the meshes, and the
effect, or appearance of too much thickness will be avoided, and at the same
time the general texture of the work will be more equal and uniform, owing to
each of the bobbin threads at each crossing working equally to produce the
crossing, and consequently each bobbin thread will work equally with its warp
threads.
The second part of the Invention also relates to the manufacture of such
descriptions of ornamented lace or net where two or more warp threads are
used, and wherein the warp threads and bobbin threads are so worked as to

page_text: produce lace having ornamental portions of cloth work therewith. It is well
known that in the manufacture of such description of ornamented lace or net,
that the bobbin threads have each been only so worked as to cross to the
extent of two neighbouring pillars. Now, the object of the present improve-
ment is, to so work the bobbin threads (when using two or more warp threads
to each bobbin thread) that the bobbin threads may work or traverse across a
distance of three pillars in making the lace portion of a fabric, by which the
fabric of ornamented lace or net will be greatly improved.
The third part of the Invention relates to a mode of working independent
instruments, which move or act on or govern the movements of the warp
threads of lace machines. In the manufacture of ornamented lace or net, it
has long been extensively the practice to employ instruments capable of acting
on the warp threads independently of each other, in order to produce varied
effects by the warp threads so acted on or governed for the time being in
their movements, from the effects produced by the other warp threads for
the time being not acted on or governed by independent instruments, and such
independent instruments have been regulated in their action by means of
jacquard cards or other suitable pattern surfaces; but in all such uses of inde-
pendent instruments at the back and at the front of the machine, they have
each at the back or at the front produced the same effect on the particular.
thread acted on by any one of them that is produced to the other of the warp.
threads at the back or at the front acted on at the same time by other
independent instruments at the back or at the front; thus, if one warp thread
at the back or at the front be governed to the extent of one or more "gates":
or spaces, all the other warp threads at the back or at the front, where the
independent instruments are brought into action by the pattern surface, will
cause the respective warp threads which they influence to be governed to the
same extent of one or more "gates or spaces, and the consequence of which
mode of working with independent instruments acting on or governing warp
threads has been that at the swing of the carriages through, between the warp
threads, the same effect in the production of the fabric has been obtained by.
each of the warp threads at the back or at the front so governed for that
swinging through of the carriages with their bobbin threads. Now, the object
of the present improvement is so to arrange and work with independent instru-
ments that the warp threads of lace machinery may be acted on or governed
thereby, so as to produce greater variety of effect than has heretofore been
obtained by the employment of independent instruments acting on warp threads
of lace machinery; and this improvement consists in so arranging independent
instruments when they act or govern the working of any of the warp threads at

page_text: the back or at the front of lace machinery, that those warp threads shall be
capable, at the same swinging through of the carriages with their bobbin threads,
of producing different or the same effects, one with the other in the fabric,
according to the requirement of the pattern, in place of each warp thread at
the back or at the front at any swinging of the carriages through the threads,
producing the same effect at the back or at the front in the fabric as has
heretofore been the result when governing the working of warp threads when
making ornamented lace or net.
The fourth part of the Invention relates to using two independent instru-
ments for acting on or governing the two warp threads used with each bobbin
thread in the manufacture of ornamented lace or net, where two or more warp
threads are used to each bobbin thread. It is well known that in the manu-
facture of ornamented lace or net, where two or more warp threads are used to
work with each bobbin thread in producing the lace or net portions as well as
the cloth work portions of the fabric, that independent instruments have been
used in order to act on or govern the working of the warp threads, but in such
cases only one instrument is employed for each pair of warp threads. Now;
the present improvement consists in applying independent instruments to each
of the additional warp threads, as well as to the ordinary warp threads, by which,
when two warp threads are employed to each bobbin thread, there will be twice
as many independent instruments as there are bobbin threads, by which more
varied effects may be produced in the producing ornamented lace or net.
The fifth part of the Invention relates to a mode of manufacturing orna-
mented lace or net, where independent instruments are used for acting on or
governing the working of the warp threads of lace machinery, and consists of so
acting on each of such independent instruments with several pattern surfaces,
or successively with different parts of the same pattern surface, that the same
independent instrument shall not be caused to produce the same degree of
effect each time that that independent instrument may be acted on by a
jacquard or other suitable pattern surface; but that the degree of effect shall
depend on the particular one of several pattern surfaces, or the particular part
of one pattern surface, which is, for the time being, brought to act on an
independent instrument used to govern the working of warp threads in the
manufacture of ornamented lace or net.
Having thus stated the objects of and the nature of the various improve-
ments secured under the present Letters Patent, I will proceed to describe the
best means I am acquainted with for performing those improvements, and in
doing so, it will not be necessary for me to enter at large into a description of
the construction and means of working lace machinery, as the same are well

page_text: The modes of working with extra threads to the bobbin threads, in order to
produce lace or net with cloth work ornaments therein, being well understood,
I have not thought it necessary to show the machinery for such purposes, and
the same has, as is well known, been heretofore performed in single tier
machinery, in some cases by numerous guide bars, and in other cases by the
use of independent instruments acting on the warp threads, and according to
the varied nature and extent of pattern of cloth work and net lace work com
bined, so have been the number of additional guide bars used, or the indepen-
dent instruments have been caused to so govern the working the warp threads
as to cause them to assume the same position (when the carriages "swing.
through), when respectively aiding to make cloth work or lace work, as if the
same warp threads were worked by extra guide bars. I have therefore thought
it the most simple mode of explaining the first and second parts of the
Invention not to enter into a description of any selected pattern consisting of
cloth work and net or lace work combined in the same fabric, as by doing so
the workman would not have been much aided in arranging other patterns, any
more than one tune in music would aid a person to arrange another tune, if
unacquainted with the value and use of each note and sign in music. I there-
fore believe a workman well acquainted with the making of net or lace as at.
present practised, when using two or more warp threads to each bobbin thread,.
will be more aided by cuts of wheels showing the arrangement necessary for
making the net or lace work wherein the crossings for forming the tops and
bottoms of the meshes are each produced by two bobbin threads, according to
the first part of the Invention, and wherein the bobbin threads are caused to
traverse a distance equal to two holes or meshes, according to the second part
of the Invention, than he would be by a selected pattern. By the means I
have pursued, a workman will readily understand what positions of the warp.
threads will bring about such mode of crossing, and such additional extent of
traversing by the bobbin threads, as will bring about his particular pattern of
fabric; and in setting up his machinery, whether to work by means of numerous
guide bars, or by means of guide bars aided by independent instruments for

page_text: acting on the warp threads, wherever in the fabric he wishes to produce the
ground of lace or net, he will cause the warp threads to be so worked, which
are for the time being aiding to make lace or net with crossings as above
described, and with extra traversings, that they may assume the positions
indicated by the cut of lace wheels, and produce the effect shewn in Figure 2
of these Drawings, where a portion of ornamented lace or net, made according
to the first and second parts of the Invention, is shown on a magnified scale.
In this Figure, a, a, a, are the warp threads, two to each bobbin thread, and
b, b, and c, c, are bobbin threads, those at 6 being colored blue, and those at c, c,
being colored green, by which the course taken by each thread will readily be
traced; and it will be seen that the bobbin threads, when aiding to make lace
or net, traverse a distance equal to two meshes, and therefore link or work
with three neighbouring pillars; and if only lace or net were required to be
made, then the four lace wheels, working with four guide bars, each guide bar
carrying as many warp threads as there are bobbin threads acting with single-
tier machinery, would be all that would be necessary; but as the Invention is
for making ornamented lace, consisting of cloth work combined with such
description of lace or net, I have shewn four other wheels, such as would be
used if the whole fabric were to be made of cloth work, such as is shown
in Figure 2, and it will be seen, on examining this Figure, that the bobbin
threads, when aiding to make cloth work, do not traverse so great a distance as
when making the lace or net work; and it will be understood, if the four cloth
work wheels were used in place of the lace wheels above mentioned, with the
same machine, then the whole fabric would be of cloth work; hence, the work-
man will readily understand that in cutting the various wheels used by him,
according to the number of guide bars employed, which, as is well understood,
depends on the nature of the patterns which it is intended to produce, he will.
so cut the wheels that they will each be composed of suitable cuts for pro-
ducing to their threads proper movements for making net or lace and cloth
work at different times, according to the pattern designed, observing the lace
wheels shown when cutting those parts of each wheel which are for the time
being to make lace or net, and the cloth work wheels are to be observed when
cutting those parts of each of the wheels which are for the time being to.
make cloth work parts of the pattern; and if independent instruments are
used, then they are to be caused to work in such manner as to cause the warp
threads to assume the same positions as if several guide bars be employed, and
this, I believe, may be best accomplished by the apparatus hereafter explained,
where every warp is acted on or governed by an independent instrument, and,
consequently, can be placed in any desired position.

page_text: Figure 1 represents a portion of ornamented lace, made with two warp
threads to each bobbin thread, according to the means heretofore practised,
where the crossings are each made with only one bobbin thread, and wherein
the bobbin threads only traverse a distance between two neighbouring pillars,
or over one hole or mesh, and the workman will readily trace the difference
of the two manufactures of ornamented lace or net as heretofore produced,
and as made according to the first and second parts of this Invention, by
comparing the pieces of ornamented lace or net shown at Figures 1 & 2.
I would remark, that when making the crossings, I prefer that the cloth
work should not be going on; and I would further remark, that although I
have been particular in shewing a particular texture of lace and of cloth work,
by indicating the directions of the threads, I do not confine myself thereto so
long as the crossings at the tops and bottoms of the meshes are each made of
two bobbin threads when working with extra warp threads, and so long as the
bobbin threads, when each working with an extra warp thread, be caused to
traverse over more than one hole or mesh as above described.
DESCRIPTION OF THE DRAWINGS MARKED No. 2.
These Drawings shew various views of a single tier lace machine in outline,
the nature of most of the parts being written thereon, and which parts are well
understood, and form no part of the Invention. The Drawings show the
machine suitably arranged for carrying out the third, fourth, and fifth parts of
the Invention, and it will only be necessary to enter into a description of the
working of the parts which are colored, in order to these parts of the Invention
being readily understood, and the workman will be facilitated in understanding
these parts of the Invention by several of the parts being shown separately
and in partial combination, and also by some of the parts being shown full
size; each of the warp threads is governed in its movements by means of
independent instruments, and the machinery is arranged for working with two
warp threads to each bobbin thread. A, A, are a series of independent sliding
bars, each having a warp thread passed through it; these sliding bars are
guided in their movements by means of combs or sleys B, B, and the warp.
threads are passed through a sley on the sley bar C, which sley bar is
rendered capable of movement in the manner of a guide bar, and according
as such sley is moved to and fro, so will be the positions in which the various
warp threads will be placed at the time the carriages swing thro' from front to.
back, or back to front. The sley bar carrying the warp threads is actuated by
its cut of wheel or other suitable pattern surface, and according to the pattern
of fabric required to be produced, so will be the various shoggings given to

page_text: such sley bar. The machinery for working the sliding bars A, A, so work
that the whole of the warp threads will be towards the front of the machine
till by the action of the jacquard or other pattern surfaces particular bars
are drawn back, when the warp threads acted on or governed by such
selected sliding bars will be drawn from front to back; and by being so
drawn or moved from front to back they will be introduced between the
stump points of the bar D, which may be a fixed bar, or may partake of the
rackings of a wheel, as is shewn, or the whole of the rackings or shoggings
given to the warp threads may be performed by the slay bar C; and it is
important to call attention to the circumstance, that as the warp threads which
are to be placed in particular positions at the back or at the front at the time
of swinging of the carriages thro' at any one time are not all simultaneously
acted on by their respective independent instruments, but can be acted on at
intervals, allowing time for the racking of the threads previously acted upon by
their independent instruments before the next quantity of warp threads are
acted on by their independent instruments, and as each selection of threads
will be received into the stumps of the stump point bar D after they have
been racked, if only the sley bar C racks their position, for the swing of the
carriages thro' will be secured so soon as they are entered into those points,
and allow of the sley bar C receiving another and a different racking with the
next selection of warp threads, and so on successively till the whole of the
threads are selected; the rackings given to the successive selections of the
warp threads not being interfered with by the previous or subsequent rackings
of other of the warp threads; thus, in place of every warp thread at the back
or at the front of the machine partaking of the same racking, one as the other,
when acted on by independent instruments for one swing of the carriages,
owing to acting on the warp threads in succession by the independent instru-
ments, each selection of threads for one swinging thro' of the carriages may
have a different racking to the other selections of threads made before and
after it for the same swing of the carriages thro' the warp threads; and thus
will the workman be enabled to work with greater extent of variety of pattern
than heretofore, and whatever be the number of such selections, they will all be
made, and the effect of the racking produced will be held secure in the stump
point bar D before the swing of the carriages takes place, and to effect this
there are two locker bars E and F, which lock up the sliding bars A so soon
as all the successive selections have been made, such locker bars E and F
being worked by their cam, as is clearly shewn in the Drawings; and the whole
of the sliding bars A are returned towards the front of the machine by means
of the locker bar G, immediately the carriages get thro' the threads, in order

page_text: to the warp threads being removed out of the stump point bar D, that a fresh
succession of selections of the warp threads may be obtained before the next
swing of the carriages, each succeeding selection of the warp threads being
racked according to the requirement of the pattern before another selection
takes place, and it is this successive selections of the warp threads, and the
obtaining separate rackings thereto, when acted on by independent instruments,
which constitutes the peculiar character of the third part of the Invention ;
and it is the using an independent instrument to work or govern each of the
two warp threads employed with one bobbin thread, when working with two
warp threads to each bobbin thread in the manufacture of ornamented lace or
net, which constitutes the peculiar character of the fourth part of this Inven-
tion. The locker bar G is worked by its cam, as is clearly shown in the
Drawings; A', A¹, are threads or cords which couple up the sliding bars A
with other sliding bars v, so that they may be worked in sets, in like manner.
to what was described in a Patent granted Mr. William Crofts, whereby the
warp threads were worked in sets, so that the acting on one set by a pattern
surface would cause all the sets to be similarly worked, without the necessity
of having pattern surfaces wide enough to act on all the independent instru-
ments; and this mode of working in sets being fully described in Mr. Crofts"
Specification enrolled on the Eigth day of March, One thousand eight hundred
and forty-three, and as the same forms no part of this Invention, no descrip-
tion will be necessary, and the mode of so working is clearly shown in
the Drawings; but in place of acting on the sliding bars v by only one
arrangement of pattern surface, as was described in the said Specification,
I cause the sliding bars and parts working therewith to be governed by a
succession of pattern surfaces acting on each of the bars v, or the bars v might
each be acted on by one pattern surface, if such pattern surface were large
enough to act by different parts of the surface, so that the times of action might
be arranged in a similar manner to what will be effected by having different
sets of pattern surfaces, as I will now describe.
The peculiar character of the fifth part of the Invention, consisting of the
manner in which several sets of pattern surfaces may be used in working with
independent instruments, or the manner in which several different parts of
each surface of one set of pattern surfaces may be used in like manner to
govern and control the working of the independent instruments, which may be
employed for like purposes. The Drawings shew that any of the independent
instruments may be acted upon by any of six different pattern surfaces, but
which number may be varied according to the object to be accomplished and
the sets of pattern surfaces, each consists of jacquard cards, but other pattern

page_text: manner.
surfaces may be used if brought to act on independent instruments in a similar
H, H, is the framing which carries the sliding bars v, and the sliding
bars will be acted on by means of the sliding bolts I, I, whenever those bolts
are-allowed by the pattern surface (for the time being acting) to descend and
come against the nebs or projections J, formed on the sliding bars v. There
are six sets of the bolts I, so that any one of the sliding bars v can be acted on
by any one of the six sets of pattern surfaces, which by the bolts succeed each
other in action. The sliding bolts I are carried in six frames, K, L, M, N, O,
and P, as is clearly shewn in the Drawing, and these bolts I are each capable
of sliding freely through its frame, so that, when permitted by the pattern sur-
face, the same will hang down in a manner to act against and move the sliding
bar v, and that bar would be moved, and the frames of bolts I, at each time
the carriages have passed through the threads, and before the carriages again
pass through the threads the frames are caused to turn partly round on their
axis, but such motion is not at the same time to each, but they succeed each
other into action; and as before stated, the warp threads selected by the first
pattern surface have time to rack and to assume and be held in their proper
positions before the selection of the next frame of bolts I acts on other of the
independent instruments to produce another selection of other warp threads, so
that they may receive their peculiar racking, and be retained in their positions
for the passage of the carriages, and so on till all the six pattern surfaces have
acted by their selection, when the whole of the warp threads will be retained
by the locker bars, as before described, in a proper position (each having its
peculiar racking) for the passage of the carriages. The nature of the frames
of bolts I being clearly shown in the Drawing, it will not be necessary to enter
into a further description thereof. The various frames, K, L, M, N, O, and P,
are caused successively to act by means of their having a crank k, l, m, n, o, p,.
to their respective axles, each crank pin carrying a roller, which is acted.
on by an inclined plane formed on a sliding bar Q, there being as many
inclined planes as there are frames of bolts I, consequently, in the arrange-
ment shown, there are six inclined planes marked respectively 1/ 2/ 3/
4/5/6/ and sliding the inclined plane (1) puts the frame K in motion,
next the inclined plane (2) puts the frame L in motion, and so on till
all the inclined planes have acted on their respective frames of bolts I,
all which will be readily understood on a careful examination of the
Drawings; and it will be seen that the sliding bar Q, with its inclined.
planes, is caused to move by means of the cam 'R, which gives motion to the
vertical bar S, which has a toothed rack formed thereon, which gives motion to
the cog wheel T, which cog wheel takes into and drives the rack V fixed on

page_text: the bar Q, all which will readily be traced in the Drawings; and the bar Qis
brought back by springs, or other convenient means. Above the apparatus I, I,
or otherwise conveniently placed, are three jacquard barrels, each barrel being
suitable for working all the independent instruments, so that each pattern per-
forated card at any time, when desired, may be capable of selecting all or any
of the sliding bars v, and consequently the warp threads worked thereby, it will
therefore be seen that each warp thread is rendered capable of being acted on
by any one of six selections during the time between one swing of the carriages
and the next swinging of the carriages, by which means an extended capability
of diversifying the patterns in producing ornamented lace is obtained, there.
being but three jacquard cylinders used, with six varieties of selections of the
independent instruments. Each card has two sets of holes or blanks, each set
being capable of selecting or omitting any one or more of the sliding bolts I; of
two frames of those bolts, the bolts I, of two frames of bolts I being coupled up
with the apparatus of one jacquard barrel; and it will be evident that if only.
one jacquard barrel were used, each surface would be required to act by means
of six different sets of holes or blanks, so as to select or miss any of the needles
or apparatus connected with the sliding bolts I of all the frames of bolts.
K, L, M, N, O, P, and as the selection of all the bolts I may take place at
the same time, whether many parts of the same pattern surface be used, or
whether several sets of pattern surfaces be used, as is shown, the pattern per-
forated or left blank of each pattern surface will be so formed as to select such
of the bolts I as may be required to act in a particular manner, whilst others
will be left, and thus will the selection of the bolts I be obtained, ready to their
being put in action by their respective frames K, L, M, N, O, and P, in sue-
cession, as described. The three jacquard barrels are actuated by means of
the cam X, which, by its lever, gives motion to the rod X', which is attached
to the arm X³, of one of the jacquard apparatus, by which means the arms X³,
which carry the barrel of the jacquard, is caused to swing to and fro; and as
the bar Y connects the axis of the jacquard barrels at one end to each other,
the giving motion to one causes the whole to move, and the necessary motion
is communicated to the jacquard barrels in order to turn them, by means of
the cam Z, which cam, by its lever, gives motion to the connecting rod Z', and
to one end of the crank lever Z2, which is connected at the other end Z³ to the
bar Z, and the hook Z5 (which is to be borne up to its barrel by a spring) is
connected with the crank lever Z³, consequently, when it is drawn downwards,
the hook Z will put in motion its jacquard barrel, and bring up a fresh card,
and the barrel will be held from movement till the card is used by means of
the catch Zo, and it will be seen that the bar Zhas similar apparatus for the

page_text: other two jacquard barrels, consequently, when motion is communicated to one
barrel, a like motion will be communicated to them all. The selections by the
cards having taken place, the bars are caused to lift the hooks, as is well
understood in jacquard machinery, and motion is given to the bars for that
purpose by means of the cam a, which, by its lever, gives motion to the con-
necting rod a', which gives motion to the arm a³ on the axis at, such axis
having arms a, which, by links a, move the bars up and down, and as the
arm a³, on each of the axis a', of the three apparatus are connected together by
means of the bar band the arms 6', all the lifting bars c, c, of the three
jacquard apparatus will be moved together.
I would remark that the third, fourth, and fifth parts of the Invention are
not confined to the using of the particular independent instruments shown for
acting on the warp threads, nor do I claim any of the jacquard apparatus, or
the parts of the apparatus connecting the independent instruments therewith,
nor do I confine myself to the use of such pattern surfaces, or such apparatus,
so long as the peculiar character of either of the third, fourth, or fifth parts of
the Invention be retained, as considerable variations in the apparatus used may.
be resorted to, and yet retain the peculiarities of novelty constituting these
parts of the Invention.
And I would wish it to be understood that what I claim is,―
First, the mode of manufacturing ornamented lace or net by causing the
crossings at the tops and bottoms of the meshes, each to be produced by two
bobbin threads, when working with two warp threads to each bobbin thread.
Secondly, I claim the mode of manufacturing ornamented lace or net, by
causing the bobbins to traverse between three pillars and over two holes, when
working with two warp threads to each bobbin thread.
Thirdly, I claim the mode of making ornamented net or lace, by acting on
the warp threads at successive intervals by independent instruments, so that
succeeding selections of warp threads may have their proper rackings, and
different from each other, for the same swinging through of the carriages, as
above described.
Fourthly, I claim the mode of manufacturing ornamented lace or net by
applying an independent instrument to govern each warp thread, when working
with two warp threads to each bobbin thread.
And, fifthly, I claim the mode of manufacturing ornamented lace or net by
so arranging pattern surfaces, in combination with independent instruments.
acting on warp threads, that the warp threads may each be capable of being
acted on by several different pattern surfaces, or several parts of the same pat-
tern surface, so that neighbouring warp threads at the back or at the front,

page_text: acted on by independent instruments, may have different rackings thereto at
the time of the swinging through of the carriages, as above described.
In witness whereof, I, the said Moses Poole, have hereunto set my
hand and seal, this Eleventh day of October, in the year of our Lord
One thousand eight hundred and forty-three.
