PROVISIONAL SPECIFICATION left by the said Clinton Edgcumbe Brooman
at the Office of the Commissioners of l'atents, with his Petition, on the
8th April 1867.
1, CLINTON EDGCUMBE BROOMAN, of the Firm of Robertson, Brooman, and
Company, of 166, Fleet Street, in the City of London, Patent Agents, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
JACQUARD MACHINERY," to be as follows:-
The object of this Invention is to arrange jacquard machinery in such
manner that it can produce two orders of treadles simultaneously (ouvrir deux
marchures), that is to say, to form two distinct angles of crossing by means of
warp threads remaining at rest, by warp threads opening an order of treadles
above these, and again by warp threads opening an order of treadles below,
thus doing away with the inconvenience of the forced order of treadles. It
will be understood that these two orders of treadles being thus open with a
batten placed in a special manner to drive at the same time two shuttles, one
in the bottom and the other in the top order of treadles, that there will be

page_text: made at the same time with the working of the cards the plain and the
figured portion for figured stuffs, or if desired two superposed or two juxtaposed
stuffs with all desirable variations of color. This system can be applied to all
kinds of weaving, as also to all kinds of fabrics, no matter of what nature, and
wherever the jacquard is employed. One of the greatest advantages derived
from it is that twice the work of the old jacquard machines is produced.
To make the different combinations constituting this system intelligible
Drawings are annexed hereto...
Figure 1 is an elevation of the machine, giving a side view of the card
cylinders or needle board; Figure 2, a plan of the machine or horizontal
section above the branch board (planche à collets); Figure 3, a vertical
section through the line C, D; Figure 4, a vertical section through the
line A, B; Figure 5, a piece of card, wood, metal, or other substance pierced
with holes of two different diameters; Figure 6, a section of this card or
plate; Figure 7, a piece of double card, with flanges at its edges superposed,
pierced with holes and fitting exactly in such manner that the top holes are
above the lower ones; Figure S, a section of the double card and of the small
plugs meant to fill when required the holes of the two cards; Figure 9, a
piece of double card like the preceding, but with more space between the top
and bottom; Figure 10, a section of this card and of the small hollow cylinders
closed at one end, and intended to fill the holes of the superposed cards; these
small cylinders are hereafter called capsules; Figure 11 is a section, but on
a larger scale, of part of Figure 3.
The ordinary lifting bar B undergoes a modification, which consists in
placing its plates or blades obliquely, the extremities of which are cut vertically
like knife blades, and in piercing the two sides touching the guides or cheeks S,S,
with holes or lengthened slits marked R, which allow the bar indescending to
interpose its blades G between the blades D of the intermediate support
hereafter spoken of, and to bring them level at the top when the machine is
at its point of rest. The blades D are grooved and brazed on two sheets of
iron fixed to each guide S with strong screws having sunken heads; they are
according to the dimensions of the machine of 600, 900, or 1,200 vertical
wires or hooks, bound and supported in cach space of one or more holes by
transverse plates making a right angle with the latter, and bearing on the
boards E and N on which they are fixed. The board E is the wire board, the

into the old jacquard mechanismwith their special position establishes one of the
mostessential points of this Invention, and theircombination constitutes whatis
hereafter called the intermediate fixed support; it has vertical or high blades.

page_text: The wires are represented in Figure 1 suspended to the blades of the lifting
bar, in Figure 3 to the blades of the intermediate support; in Figure 4 one
wire is suspended from one of the lifting bar blades, another is suspended to a
blade of the support, and a third rests on the branch board (planche à
collets) F. Figure 11 gives a larger view of the wires fin three different
positions. The branch board F is pierced at its four extremities with sockets,
by means of which it is slipped on round rods fixed at the top to the
uprights of the guides, and at the bottom on a frame attached to these same
guides, and connecting them by means of bolts; or it can be guided by
means of grooves and bolts like the lifting bar.
All the parts of the machine being now explained I proceed to describe the
mode of operation.
The action or motion is transmitted by the aid of a lever P with double
branches, having its points of support on the cross bar V; this lever is
united to the beam A by means of the rod O, and the direct action is given
to it by the rod Q. Motion being given and the rod Q exerting traction on
the lever P, and this movement being communicated by the rod O to the
beam A,
this raises the lifting bar a certain height, say about 3 inches; this
same lever P, acting by means of the jointed cranks J on two shafts I held by
two cross pieces H, will make by a raising and lowering movement (shewn in
Figures 1, 2, 3, and 4,) the branch board F descend a distance of about 3
inches;
these two parts will thus be widened with regard to their first position
an equal distance above and below the intermediate support; or the move-
ment of the branch board F maybe obtained by means of "coopers" (bricoteaux)
worked by the lifting bar, and the movements of which are aided and regulated
like those produced by the lever Pby means of a counterweight. In machines
where these coopers are generally employed they only divide the order of
treadles, whereas in this system they permit by means of the intermediate
support of establishing two orders of treadles, one ascending and the other
descending.
In Figure 4, which I now proceed to describe, M is the thread bar; N, the
bar of the stuff; O, its support, with mortices for the parts; P, the bench or
supporting table; and Q, its support. In Figure 4 are represented 8
wires, one hung to the blade C of the lifting bar at its highest point, the
other to the blade D of the intermediate support in the resting position, and
the third resting on the branch board F entirely descended; the shoulders or
heels are at f, f, f. By means of the twine (arcade), the heald, the
loop or stitch, and the leads (fuseau) the heel f₁ suspended to the blade of
the lifting bar will make the warp thread passing into the loop of bar M

page_text: at the extremity of the stuff U follow a broken or irregular line, the summit
of the angle of which at the point R will be found at a height of about
3 inches from the line of rest, and will thus open the top order of treadles,
the heel suspended to the blade of the intermediate support will be at
rest, and with it the warp thread passing into its loop at the point R'. Tho
heel resting below on the branch board F will lower its loop to the point R",
and open by the aid of the warp thread passing inside a triangle nearly like that
above, that is to say, a lower order of treadles; this being the case, and the
batten working its two shuttles at the same time in the two orders of treadles
respectively, there will be made at will without a lost stroke the plain and the
figured portions, two superposed or two juxtaposed stuff's; this last result is
very advantageous as it permits the workman to see two sides of the stuff.
The systems of cards will now be described, systems which work the
wires and permit of making them rest at will on the blades of the
lifting bar B, on those of the intermediate support, and on the branch
board F. The wire board E, Figure 11, is perforated with holes of the
diameter of those of the cylinder. The horizontal wires which are colored
blue, and which to 2 lines from their extremity at the side of the card F
are of the ordinary thickness, are enlarged for a length of about 7 lines by
small cylinders sliding freely in the corresponding holes in such manner
as to fill the opening without friction, and passing through the board Fa
distance of 4 lines; when from the movement of the machine all the wires
that were at rest, that is to say, having their head at the height of the
blades of the intermediate support, are immediately lifted by the branch board
about 4 lines; at this time the cylinder Y presses the card F. upon the wire
board E. In front of the horizontal wire Z, the card not being perforated,
the wire will be pushed, and the hook or wire f will descend with the branch
board; the wire Z being in front of a hole in the card will not be pushed,
and the hook or wire f¹ will be raised with the lifting bar; the wire Z being
before a hole smaller than its enlargement or cylinder, the hook or wire fl
will be pushed 2 lines, only enough to escape the lifting bar, and remain
suspended to a blade of the intermediate support.
Figures 5 and 6 shew the cards or plates with holes of two different
diameters. Each card is originally perforated regularly with holes of the same
diameter, and it is in the operation of reading and according to the design
to be obtained that some of the holes are stopped with plugs and others with
hollow capsules which make smaller holes. If the machine is supposed to be
working the lifting bar will rise, and with it the wire f; the wire f¹ will
follow the branch board on which it rests and will descend, and the wire f

page_text: will remain stationary, having its head always at an equal distance from the
two others; in this movement O will be raised to O¹, the line of the top of
the blades C of the lifting bar Q will be raised to E¹, and the bottom part
of the hook which was before on the line Qwill descend to the line P; by
continuing the movement the effect before described and seen in Figure 4
will be obtained. There is still another means of working the wires (see
Figures 9 and 10). Take a system of plates of any material, say zinc, formed
of two plates with flanges fitting one in the other and perforated with
juxtaposed holes corresponding to those of the cylinders of the wires Z', and
held together at each extremity by a pin passing into four lugs sliding in
grooves; two lugs are fixed above the box and the other two underneath,
or adapted by other means. Now arrange conveniently small cylinders L'
(Figure 10) between the two plates L. (Figures 9 and 10), each small cylinder
having, for example, 2 lines of depth, and afterwards apply this double plate
or new description of card in the place of F, then it will be seen, by supposing
ordinary wires are used, whenever there are not small cylinders like L' the
wire will not find any obstacle, and the vertical hook or wire will rest
on the blade of the lifting bar; if the small cylinder is reversed, so as
to put the bottom at the top, it will make the plate level and will entirely
push the wire and with it the vertical hook or wire in such manner that
it will rest only on the branch board in front of L', the needle being
pushed only 2 lines will drive the hook or vertical wire as well, which
escaping from the blade of the lifting bar will rest suspended to a blade of
the intermediate support, and the same effect as before will be accomplished.
Figures 7 and 8 represent similar plates, but not so far apart; they are
intended to replace the ordinary cards for the old arrangement, whether the
holes are left open or stopped, as at K, with the plugs K¹. The employment
of these two kinds of double plates, which will become, so to speak, perpetual,
and which can be made very exact and very cheap, will be a great saving
when compared with the ordinary cards. These results before described may
be also obtained by using hooks or wires with two heads of the same height
jointed above the branch board and enlarged to prevent their passing beyond,
having a single heel below this board, only in using these hooks there must
be two horizontal wires to one hook, or one for each branch or arm, and the
blades of the lifting bar are vertical and differently placed. The arrangements
which have been given can be variously modified; the branch board may, for
example, be placed in such a manner that the grooves or mortices of the iron
plate which covers it are in front of the iron rods; in this case the two heads
of the hook would be in reversed directions; no matter what be the form and

page_text: arrangement of the hooks or vertical wires it suffices if they do not escape the
branch board, on which they must be kept at a height from the bottom of the
heel, which will be the same for all. The escape of the heads of the hooks
above the blades of the lifting bar and of those of the intermediate support
when they level themselves can be again obtained by means of the branch
board, which at rest holds them all above these last..
In conclusion I may state that the main points or principle of this Invention
are,-
1, the idea of working two independent orders of treadles in the jacquard
mechanism, the one above and the other below, that is to say, two distinct
symmetrical angles of crossing, ascending and descending, setting out from
the same fixed starting point or position of rest or equilibrium, this position
being furnished by a new part or organ which is the intermediate support
herein-before described.
2, the substituting for the cards, which are ordinarily changed for each design,
of plates or cards that will serve over and over again, and the arrangement of the
holes of which and consequently of the designs are capable of being varied to any
extent; this suppresses the ordinary reading and the perforation of the cards.
3, the employment of an intermediate fixed support provided with high
or vertical blades or plates to stop and keep at rest the hooks or vertical
wires in the position of equilibrium.
4, the combination of this support with the lifting bar on the one hand
and with the movable branch board on the other with the view of harmonizing
the action of the hooks or wires by these three parts in order to place them in
the three positions herein-before mentioned, the top, the equilibrium, and the
bottom positions, with theobjectofopening aboveandbelow thetwo independent
orders of treadles.
6, the arrangements before described of the single or double plates or cards
perforated regularly with holes of the same diameter to replace the cards now in
use; these plates will serve indefinitely, and will be adapted to differentdesignsby
means of plugs or hollow capsules to stop or modify the perforations of the plates
by rendering them narrower or shallowerso as to act on the horizontalwires with
enlargements or on the ordinary horizontal wires. In the case of wires with
enlargements the parts of the plates which are opposite the wires are of three
natures; these are the original holes, or these holes narrowed, or full parts result-
ing from plugged holes; in the second case the holes instead of being narrowed
are shortened in their depth; in every case the full parts or plugged holes produce
the descending order of treadles with the branch board, the holes half stopped
with the plugs or capsules produce the position of equilibrium with the

page_text: intermediate support which keeps the vertical hooks or wires at rest, and
the holes quite open produce the ascending order of treadles with the ordinary
lifting bar.

by the said Clinton Edgcumbe Brooman in the Great Seal Patent Office
on the Sth October 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, .I, CLINTON
EDGCUMBE BROOMAN, of the Firm of Robertson, Brooman, and Company, of
166, Fleet Street, in the City of London, Patent Agents, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of April, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Clinton Edgcumbe Brooman, Her special licence that I, the said
Clinton Edgcumbe Brooman, my executors, administrators, and assigns, or
such others as I, the said Clinton Edgcumbe Brooman, 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 nake, 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," (com-
municated to me from abroad by Jean Pierre Lachaud and Henri Simon
Roussel, both of Paris, France,) upon the condition (amongst others) that I,
the said Clinton Edgcumbe Brooman, 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 is to be performed, and cause the same to be
filed in the Great Seal Patent Office within six calendar mouths next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Clinton Edgcumbe Brooman, 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 thereof, reference being had to the Drawings hereunto
annexed, that is to say:-
The object of this Invention is to arrange jacquard machinery in such
manner that it can produce two orders oftreadles simultaneously (ouvrir deux

page_text: marchures), that is to say,
to form two distinct angles of crossing by means of
warp threads remaining at rest, of warp threads opening an order of treadles
above these, and again of warp threads opening an order of treadles below,
thus doing away with the inconveniences of the forced order of treadles. It
will be understood that these two orders of treadles being thus open with a
batten placed in a special manner to drive at the same time two shuttles, one
iu the bottom and the other in the top order of treadles, that there will be
made at the same time with the working of the cards the plain and the figured
portion for figured stuffs, or if desired two superposed or two juxtaposed
stuffs with all desirable variations of color. This system can be applied to all
kinds of weaving, as also to all kinds of fabrics, no matter of what nature, and
wherever the jacquard is employed. One of the great advantages derived from
it is that twice the work of the old jacquard machines is produced.
To make the different combinations constituting this system intelligible
Drawings are annexed hereto.
Figure 7 is an elevation of half the machine, giving a side view of the card
cylinders or needle board; Figure 2, a plan of the machine or horizontal
section above the branch board (planche à collets); Figure 3, a vertical section
through the line C, D; Figure 4, a vertical section of half the machine.
through the line A, B; Figure 5, a piece of card, wood, metal, or other
substance pierced with holes of two different diameters; Figure 6, a section
of this card or plate; Figure 7, a piece of double card, with flanges at its
edges superposed, pierced with holes and fitting exactly in such manner that
the top holes are above the lower ones; Figure 8, a section of this double
card and of the small plugs meant to fill when required the holes of the two
cards; Figure 9, a piece of double card like the preceding, but with more
space between the top and bottom; Figure 10, a section of this card and of
the small hollow cylinders closed at one end, and intended to fill the holes
of the superposed cards; these small cylinders are hereafter called capsules;
Figure 11, a section, but on a larger scale, of part of Figure 3.
The ordinary lifting bar B undergoes a modification, which consists in placing
its plates or blades obliquely, the extremities of which are cut vertically like
knife blades, and in piercing the two sides touching the guides or cheeks S, S,
with holes or lengthened slits marked R, which allow the bar in descending
to interpose its blades G between the blades D of the intermediate support
hereafter spoken of, and to bring them level at the top when the machine is
at its point of rest. The blades D are grooved and brazed on two sheets of
iron fixed to each guide S with strong screws having sunken heads; they are
according to the dimensions of the machine of 600, 900, or 1,200 vertical

page_text: wires or hooks bound and supported in each space of one or two holes by
transverse plates, making a right angle with the latter, and bearing on the
boards E and N, on which they are fixed. The board E is the wire board,
the board N the case board or spring box. The introduction of these blades D
into the old jacquard mechanism with their special position is one of the most
essential points of this Invention, and their combination constitutes what is
hereafter called the intermediate fixed support; it has vertical or high blades.
The wires fare represented in Figure 1 suspended to the blades of the lifting
bar, in Figure 3 to the blades of the intermediate support; in Figure 4 one
wire is suspended from one of the lifting bar blades, another is suspended to
a blade of the support, and the third rests on the branch board (planche à
collets) F. Figure 11 gives a larger view of the wires fin three different
positions. The branch board F is pierced at its four extremities with sockets,
by means of which it is slipped on round rods & fixed at the top to the uprights
of the guides, and at the bottom on a frame attached to these same guides,
and connecting them by means of bolts; or it can be guided by means of
grooves and bolts like the lifting bar.
All the parts of the machine being now explained, I proceed to describe
the mode of operation.
The action or motion is transmitted by the aid of a lever P with double
branches, having its points of support on the cross bar V; this lever is united
to the beam A by means of the rod O, and the direct action is given to it by
the rod Q. Motion being given and the rod Q exerting traction on the
lever P, and this movement being communicated by the rod O to the beam A,
this raises the lifting bar a certain height, say about 3 inches; this same
lever P, acting by means of the jointed cranks J on two shafts I held by two
cross pieces H, will make by a raising and lowering movement (shewn in
Figures 1, 2, 3, and 4,) the branch board F descend a distance of about
3 inches; these two parts will thus be widened with regard to their first
position an equal distance above and below the intermediate support; or the
movement of the branch board F may be obtained by means of "coopers
(bricoteaux) worked by the lifting bar, and the movements of which are aided
and regulated like those produced by the lever Pby means of a counterweight.
In machines where these "coopers" are generally employed they only divide
the order of treadles, whereas in this system they permit by means of the
intermediate support of establishing two orders of treadles, one ascending and
the other descending.

In Figure 4, which I now proceed to describe, M is the thread bar; N, the
the bench or
bar of the stuff; O, its support, with mortices for the parts; P,

page_text: supporting table; and Q, its support.
or stitch,
In Figure 4 are represented 3 wires f,
one hanging to the blade G of the lifting bar at its highest point, the other to
the blade D of the intermediate support in the resting position, and the third
resting on the branch board Fentirely descended; the shoulders or heels are
at ff. By means of the twine (arcade), the heald, the loop
and the leads (fuseau), the heel f¹ suspended to the blade of the lifting bar
will make the warp thread passing into the loop of the bar M at the extremity
of the stuff U follow a broken or irregular line, the summit of the angle of
which at the point R will be found at a height of about 3 inches from the
line of rest, and will thus open the top order of treadles, the heel f¹¹ suspended
to the blade of the intermediate support will be at rest, and with it the warp
thread passing into its loop at the point R. The heel/11 resting below on
the branch beard F will lower its loop to the point R11, and open by the aid
of the warp thread passing inside a triangle nearly like that above, that is to
say, a lower order of treadles; this being the case, and the batten working its
two shuttles at the same time in the two orders of treadles respectively, there
will be made at will without a lost stroke the plain and the figured portions,
or two superposed or two juxtaposed stuffs; this last result is very advantageous,
as it permits the workman to see two sides of the stuff.
The systems of cards will now be described, systems which work the
wires and permit of making them rest at will on the blades of the lifting
bar B,on those of the intermediate support, and on the branch board F. The
wire board E, Figure 11, is perforated with holes of the diameter of those of
the cylinder. The horizontal wires which are colored blue, and which to 2
lines from their extremity at the side of the card F are of the ordinary
thickness, are enlarged for a length of about 7 lines by small cylinders sliding
freely in the corresponding holes in such manner as to fill the opening without
friction, and passing through the board E a distance of 4 lines; then from
the movement of the machine all the wires which were at rest, that is to say,
having their head at the height of the blades of the intermediate support, are
immediately lified by the branch board about 4 lines; at this time the
cylinder V presses the card F upon the wire board E. In front of the hori-
zontal wire Z, the card not being perforated, the wire will be pushed, and the
hook or wire will descend with the branch board; the wire Z being in
front of a hole in the card will not be pushed, and the hook or wire f¹ will be
raised with the lifting bar; the wire Z being before a hole smaller than its
enlargement or cylinder, the hook or wire will be pushed 2 lines, only
enough to escape the lifting bar, and remain suspended to a blade of the
intermediate support.

page_text: Figures 5 and 6 shew the cards or plates with holes of two different
diameters. Each card is originally perforated regularly with holes of the same
diameter, and it is in the operation of reading and according to the design to
be obtained that some of the holes are stopped with plugs and others with
hollow capsules which make smaller holes. If the machine is supposed to be
working the lifting bar will rise, and with it the wire f¹; the wire f¹ll will
follow the branch board on which it rests and will descend, and the wire fil
will remain stationary, having its head always at an equal distance from the
two others; in this movement ( will be raised to O', the line of the top of
the blades G of the lifting bar Q will be raised to E', and the bottom part
of the hook which was before on the line Qwill descend to the line P; by
continuing the movement the effect before described and seen in Figure 4 will
be obtained. There is still another means of working the wires (see Figures
9 and 10). Take a set of plates of any material, say zinc, formed of two
plates with flanges fitting one in the other and perforated with juxtaposed
holes corresponding to those of the cylinders of the wires Z', and held together
at each extremity by a pin passing into four lugs sliding in grooves; two lugs
are fixed above the box and the other two underneath, or adapted by other
means. Now arrange conveniently small cylinders L', Figure 10, between
the two plates L (Figures 9 and 10), each small cylinder having, for example,
2 lines of depth, and afterwards apply this double plate or new description
of card in the place of F, then it will be seen, supposing ordinary wires are
used, that wherever there are not small cylinders like L' the wire will not find
any obstacle, and the vertical hook or wire will rest on the blade of the lifting
bar; if the small cylinder is reversed, so as to put the bottom at the top, it
will make the plate level and will entirely push the wire and with it the
vertical hook or wire in such manner that it will rest only on the branch
board in front of L', the needle being pushed only 2 lines will drive the
hook or vertical wire as well, which escaping from the blade of the lifting
bar will rest suspended to a blade of the intermediate support, and the same
effect as before will be accomplished. Figures 7 and 8 represent similar
plates, but not so far apart; they are intended to replace the ordinary cards
for the old arrangement, whethere the holes are left open or stopped, as at K,
with the plugs K¹. The employment of these two kinds of double plates,
which will become, so to say, perpetual, and which can be made very
exact and very cheap, will be a great saving when compared with the ordinary
cards. These results before described may be also obtained by using hooks
or wires with two heads of the same height jointed above the branch board
and enlarged to prevent their passing beyond, having a single heel below this

page_text: board, only in using these hooks there must be two horizontal wires to one
hook, or one for each branch or arm, and the blades of the lifting bar are
vertical and differently spaced. The arrangements which have been given
can be variously modified; the branch board may, for example, be placed in
such a manner that the grooves or mortices of the iron plate which covers it
are in front of the iron rods; in this case the two heads of the hook would be
in reverse directions; no matter what be the form and arrangement of the
hooks or vertical wires it suffices if they do not escape the branch board,
on which they must be kept at a distance from the bottom of the heel, which
will be the same for all. The escape of the heads of the hooks above the
blades of the lifting bar and of those of the intermediate support when they
become level can be again obtained by means of the branch board, which at
rest holds them all above these last.
And having now described the nature of thesaid Invention of "Improvements
in Jacquard Machinery," and in what manner the same is to be performed, I
declare that I claim,-
1st, the working of two independent orders of treadles in the jacquard
mechanism, the one above and the other below, as herein-before described,
that is to say, two distinct symmetrical angles of crossing, ascending and
descending, setting out from the same fixed starting point or position of rest or
equilibrium, this position being furnished by a new part or organ which is the
intermediate support herein-before described.
2nd, the manufacture and the substitution for the cards, which are
ordinarily changed for each design, of plates or cards, substantially as berein-
before described, which will serve over and over again, and the arrangement
of the holes of which and consequently the designs are capable of being
varied to any extent; this suppresses the ordinary reading and the perforation
of the cards.
3rd, the construction and employment of an intermediate fixed support,
substantially as herein-before described, provided with high or vertical blades
or plates to stop and keep at rest the hooks or vertical wires in the position of
equilibrium.
4th, the combination of this support with the lifting bar on the one hand
and with the movable branch board on the other, as herein-before described,
with the view of harmonizing the action of the hooks or wires by these three
parts in order to place them in the three positions herein-before mentioned, the
top, the equilibrium, and the bottom positions, with the object of opening above
and below the two independent orders of treadles.
5th, the arrangements herein-before described of the single or double

page_text: plates or cards perforated regularly with holes of the same diameter to replace
the cards now in use, these plates serving indefinitely, and being adapted to
different designs by means of plugs or hollow capsules to stop or modify the
perforations of the plates by rendering them narrower or shallower so as to
act on the horizontal wires with enlargements or on the ordinary horizontal
wires. In the case of wires with enlargements the parts of the plates which
are opposite the wires are of three natures; these are the original holes, or
these holes narrowed, or full parts resulting from plugged holes; in the
second case the holes instead of being narrowed are shortened in their depth;
in every case the full parts or plugged holes produce the descending order of
treadles with the branch board, the holes half stopped with the plugs or cap-
