Street, Strand, in the County of Middlesex, Patent Agent, for the
Invention of "IMPROVEMENTS IN LOOMS FOR WEAVING." -A communi-
cation from abroad by Emile Olivier Petit-Toulouse, of Homblières,
Aisne, France.
PROVISIONAL SPECIFICATION left by the said William Edward Gedge
at the Office of the Commissioners of Patents, with his Petition,
on the 8th June 1872.
I, WILLIAM EDWARD GEDGE, of No. 11, Wellington Street, Strand,
in the County of Middlesex, Patent Agent, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN LOOMS FOR WEAVING,"
a communication to me from abroad by Emile Olivier Petit-Toulouse, of
Homblières, Aisne, France, to be as follows:-
This loom, which is constructed upon an entirely new system, affords
the immense advantage of uniting with the softness and suppleness of
band weaving the rapidity of power loom weaving, thereby permitting
the manufacture of a variety of articles which unable to support the

page_text: Sheet III., right side view.
The capital letters indicate the parts of the primitive loom of this
Invention, and the italics the pieces forming modifications and improve-
ments therein.
An examination and comparison of the three views of the Drawings
might permit the working of the loom to be followed, nevertheless
explanations of each part will be found useful to facilitate research and
define the effects; and I will proceed to give this explanation as clearly
as possible.
And, firstly, it is necessary to observe that in order the better to
follow its details and accessaries the cording. ("armure") has been
drawn to a larger scale than actual size, and it therefore necessarily
follows that the pieces in connection with it appear a little further apart
on the Drawing than they are in the actual loom.
The proper place of the Figure 1* (Sheet III.) is not where it is
drawn, its true position being a little behind the extended line of the
batten in front of the rollers e, by which it receives impulsion from the
hooks or lifting wires ("crochets") Nos. 1 and 2.
The pieces G, F, E, H, and P of Fig. 1, Sheet I. are in the actual
loom about the same height as shown, Figure 1, Sheet II. They are
arranged in echelon in the front view in order that they may all be.
shown according to their length.
The twelve cords coming on to the twelve lifting wires of the cording
(Fig. 1, Sheet I.), are also diverted from their natural view (which
would be a simple line), the better to follow their arrangement and
working, which it might be difficult to seize from Fig. 1, Sheet III.
The roller e is upon Fig. 1, Sheet I., drawn a little smaller than on
Sheet III., in order that it may less hide the draught cords (" fils con-
ducteur") of the cording.

page_text: The toothed wheel a set on the horizontal shaft, at the end of which
is the crank 6, serves for the transmission of the motive power (Fig. 1,
Sheet I.).
"
The grooved connecting rod c obeys the crank b to produce the
lowering of the marche ("contre-márche ") d by its passage over the
end thereof. This connection rod is guided by a fixed pin passing into
the groove at the point c'. The Drawing of this rod represents two of
the positions which it occupies during its action upon the marche (Fig. 1,
Sheet I.).
The treadle A. receives its motion from the marche d by the end
which comes beneath it.
It will be understood that the treadle A, as well as the marches d,
must have one end set upon pivots to produce the effect of levers,
drawing towards them all the resistances of the loom.
The roller B receives a rotary motion by its connection with the
treadle A (see Sheets II. and III., Fig. 1).
Motion is given to the roller C placed at the upper part of the loom,
and from thence to the part termed the grif or lifting bar of a cording
or simple jacquard mechanism D (see Figures 1, Sheets I. and III.).
As nearly all the effects produced in the loom depend upon the
functions of this cording, it is necessary to explain its mechanism, which
will naturally lead to a knowledge of these effects.
The lifting wires, which are twelve in number, are fork-shaped, as
be
may seen at Fig. 2, Sheet IlI. The hind branch bearing against a
rod at the top, and held below by a heddle hook ("passette") forms
spring, so that the main branch may join the cylinder 0³, which actuates
it by small notches at the moment when it is to work.
The main branches of the lifting wires, Nos. 1, 2, 3, 4, 5, 6, 9, and 10,
have the shape of actual hooks. Those Nos. 7 and 8 are straight,
because they are driven back instead of being lifted off. Those of
Nos. 11 and 12 are bent over to square, in order that they may escape
at half course by the aid of a tie ("attache"), which regulates their
journey (see Fig. 2, Sheet III.). Each of these lifting wires is provided
with a small spring, which draws it back by the lower part. The Nos. 5
and 6 have one at each end; that at the upper part is more powerful.
than the other, in order that the lifting wire may always rise again after
accomplishing its work.

page_text: The cylinder Ox is shown in its place at Fig. 1, Sheet III., and on its
four sides, Fig. 3, same Sheet. The Drawing shows that the small
notches in coming before the lifting wires by the rotation produced by
the catch ("clichet ") *P, *P (Sheet III., Fig. 1,), at each elevation of
the grif permits the lifting wires to work at the proper time. In pre- 5
senting these notches to the lifting wires the cylinder 0 actuates :-The
first face, the Nos. 1, 4, 8, 9, 10, and 11, for the gauze treadle or gauze
shed ("pas de gaze"); the second face, the Nos. 1, 5, 7, 8, and 11, for
the figuring treadle or figuring shed ("pas de broché"); the third face,
1
the Nos. 2, 3, 4, and 12, for the heavy treadle or heavy shed ("pas
dur"); the fourth face, the Nos. 2, 6, 7, 8, and 12, for the figuring
treadle or figuring shed ("pas de broché ").
To thoroughly define the preceding I will now follow the progress of
the effects produced by 'each separate lifting wire.
The 1st and 2nd lifting wires pull by cords or by metal rods the
large catches ("clichets") Q, Q, which take the slanting position Q', Q',
permitting the escape of the cross pieces R, R, which fall to R', R, by
means of the weights attached to them (see Fig. 1, Sheet I., and Fig. 1*,
Sheet II.). These movements take place at the moment when the
roller C permits the slackening of the cords passing over U, U. These
movements cause the swinging of the pieces S, S, which place them-
selves at S¹, S¹, so as to draw sharply the whips ("foucts") T to T"
by the aid of the cords passing over the pulleys X*. These whips,
furnished with peckers ("taquets") drive the shuttles from one end of
the batten to the other. The two lifting wires act alternately; the 1st
on the right, and the 2nd on the left side.
The 3rd lifting wire lowers the 2d lifting blade ("lame") by the aid
of the "cooper" ("bricoteau ") E. This 2nd lifting blade lifts the 1st by
the communication of the cords passing over a small roller This is
what produces the hard treadle or hard shed (“pas dur”).
g.
The 4th lifting wire lifts the boxes of the batten M by the cords
which connect it with the " cooper" P, the roller O, and boxes N.
This movement is regulated by the piece Z' (Fig. 1, Sheet I., and Fig. 1,
Sheet II.), which is attached to the cord passing from the 4th lifting
wire to the "cooper" P. This piece Z' rises at the same time as this
cord, and stops at the position Z upon a catch ("clichet") (Figures 1
"

page_text: and 4, Sheet III.) to keep the boxes suspended during the passage of
the shuttles. This passage accomplished, the boxes fall again by the
release of the catch Z, effected by the cord on the roller C, aided by the
small roller Zx (Figures 1 and 4, Sheet III.).
The 5th and 6th lifting wires work inversely to the others. They are
driven back by the "grif" instead of being carried off. They com-
municate by means of the small pulleys r and of a ring placed at the
lower part of the batten, on the right side, with the jointed part of a
slide n (Fig. 1, Sheet I., and Figures 1,5, and 6, Sheet III.). The
operation of these lifting wires combines with that of the two forks
placed at each end of the slay ("peigne"); as may be seen Fig. 1,
Sheet I., and better at Figures 5 and 6, Sheet III., where they are seen
from above. This combination leaves the weft free action in the fork,
so that when the shoot breaks, this fork being no longer upheld in line
with the slay, the slide n drawn by its spring assumes an upright
position, coming against the batten, as may be seen Fig. 6, Sheet III.
The shock thus produced pushes the moveable part of the marche d' (sec
Fig. 6, Sheet III.), which places it out of reach of the rod c by the
shifting of the picco 1, which goes to ', stopping the loom. This
stoppage continues until the catch ("clichet") d", which had fallen
to d by the pulling of a spring, is raised by a special cord, and permits
the marche to resume its straight position, as shown Fig. 5, Sheet III.
The 7th lifting wire actuates the jacquard mechanism X by means of
the cords attached to the slays, "balanciers," F and V, see Fig. 1,
Sheets I. and II.
The 8th and 9th lifting wires operate the cooper f, which by its.
fastenings, "attaches," releases the back short arm or lever ("courts-
bras") o' (Fig. 1, Sheet II.) at the moment of the passage of the gauze
and figuring sheds ("pas de gaze et de broché"). There are here two
lifting wires for the same object, because for the "broohé "shed the
short arm must lower more than for the other.
The 10th lifting wire lowers the 4th lifting blade ("lame") by means
of the cooper G. This lifting blade causes the 3rd to rise by the aid of
the 2nd roller g' (see Fig. 1, Sheet II.). These two operations produce
gaze").

shed ("pas de
It has not been possible to draw upon Sheet I. more than one lifting
bar ("lame") to show the place occupied by them and their short levers

page_text: ("courts bras"), but at Fig. 1, Sheet II., these lifting bars are drawn,
and numbered from 1 to 4, and the short levers are marked o, o'.
.
The 11th and 12th lifting wires communicate with two small catches
("clichets") placed on each upright of the batten between the boxes N
and the slay ("peigne") (see Figures 1 of the three Sheets). These small
catches serve as stops to two small hinged rods m, through which they
pass. At the lower end of these rods are cords which pass behind the
batten and communicate with two other larger slotted or sliding catches
("clichets à coulisses") i, i, placed in the middle of the loom on each
side of the treadle A. This communication takes place by means of ]
cords and small rollers t, u, v*. (see Figures 1, Sheets I. and III., and
Figures 1, 2, 3, 4, Sheet II.). The Figure 2, Sheet II., represents a
portion of the batten seen from behind to show the position of the
draught threads ("fils conducteurs ") and of their rollers t, u.
The two catches i, i, have slots ("coulisses"), in order that if the 1
shuttle should diverge or remain in the shed ("pas") the loom shall be
instantaneously stopped. In this case the catches i, ¹, are lifted by the
treadle A, with which they gear, and give motion to a hook or catch k,
which in taking the position k¹ actuates the marche d', placing its end
outside the course of the connecting rod c. The displacement of the 2
moveable part of the marche is facilitated by the pieces h, which are
drawn to h¹ with it.
To complete the explanation of these somewhat complicated move-
ments, it is desirable to state that the action of the lifting wires 11
and 12 is combined with the draught ("passages") of the shuttle :
("navette"), so as to leave to this latter all its action upon the draught
of the catches i, , that is to say, that on the side upon which the shuttle
does not act the opposite lifting wire replaces it, so that as long as the
loom works regularly these catches i, i, are in the position shown Fig. 1,
Sheet I., and Fig. 3, Sheet II. Directly the shuttle misses its stroke
these catches i, i, place themselves as shown Fig. 2, Sheet II. This
latter explanation applies also to the lifting wires 5 and 6 for their
alternate action with the shoot acting in the forks.
After this long description, which should cause the action of the loom
to be thoroughly understood, there remains only to set forth the move-
ments of the batten M, which alone are outside of the action of the
lifting wires of the cording..

page_text: The lever H attached to the treadle A communicates by means of a
pulley K with two rods I, which are united in the middle of the loom
by a pivot or bolt fixed in the batten M, so that at each movement of
the treadle A a recoil motion takes place following the first position of
the piece I, Fig. 2, Sheet I. Directly the treadle A rises again the
batten again comes forward by the action of the weight J on the piece I,
aided by the pulley L. This forward movement produces the action
known as milling ("draper"). At this moment the position of the
piece I is advanced as shown at I', Fig. 2, Sheet I.
The frame of the loom is not completely drawn, nor the supports of
the various coopers ("biscoteaux "), rollers, pulleys, and accessaries, in
order not to further complicate the lines of the Drawing. This insig-
nificant want can be easily supplied.
The recall of the cylinders of the "jacquard" and of the cording, as
well as the freeing of the hook or catch d", d, take place as usual by
cords placed according to the pleasure of the weaver.
All the springs are spiral shaped and of slight brass wire, excepting
that of the see-saw or swing which works with the "grif," which requires
to be stronger, because after being shifted by the roller C its spring must
make a somewhat powerful effort to assist this roller in lifting the cross
picces R and their weights R₁ (see Fig. 1, Sheet I., and Figures 1
and 1*, Sheet III.)

SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Edward Gedge in the Great Seal Patent
Office on the 7th December 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, 'I, WILLIAM
EDWARD GEDGE, of No. 11, Wellington Street, Strand, in the County
of Middlesex, Patent Agent, send greeting:
WHEREAS Her most Excellent Majesty Queen Victoria,, by Her
Letters Patent, bearing date the Eighth day of June, in the year of
our Lord One thousand eight hundred and seventy-two, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said William Edward Gedge, Her special
licence that I, the said William Edward Gedge, my executors, admi-

page_text: nistrators, and assigns, or such others as I, the said William Edward
Gedge; my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after 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 LOOMS FOR WEAVING," a communication to me from
abroad by Emile Olivier Petit-Toulouse, of Homblières, Aisne, France,
upon the condition (amongst others) that I, the said William Edward
Gedge, my executors or administrators, by an instrument in writing 1
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 William Edward Gedge, 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, reference being had to the accom-
panying Sheets of Drawing, and to the figures and letters of reference 2
placed thereon :-
This loom, which is constructed upon an entirely new system, affords
the immense advantage of uniting with the softness and suppleness of
hand weaving the rapidity of power loom weaving, thereby permiting
the manufacture of a variety of articles, which, unable to support the 2
rigidity of ordinary power looms, could hitherto only be made by slow
and costly methods.
The accompanying three Sheets of Drawing represent the three

page_text: nations of each part will be found useful to facilitate research and
define the effects, and I will proceed to give this explanation as clearly
as possible.
And, firstly, it is necessary to observe that in order the better to follow
its details and accessaries the cording ("armure") has been drawn to a
larger scale than actual size, and it therefore necessarily follows that the
pieces in connection with it appear a little further apart on the Drawing
than they are in the actual loom.
The proper place of the Figure 1* (Sheet III.) is not where it is
drawn, its true position being a little behind the extended line of the
batten in front of the rollers e, by which it receives impulsion from the
hooks or lifting wires ("crochets ") Nos. 1 and 2.
The pieces G, F, E, H, and P, of Fig. 1, Sheet I., are in the actual
loom about the same height, as shown, Fig. 1, Sheet II. They are
arranged in echelon in the front view, in order that they may all be
shown according to their length.
The twelve cords coming on to the twelve lifting wires of the cording
(Fig. 1, Sheet I.), are also diverted from their natural view (which would
be a simple line), the better to follow their arrangement and working,
which it might be difficult to seize from Fig. 1, Sheet III.
The roller e is upon Fig. 1, Sheet I., drawn a little smaller than on
Sheet III., in order that it may less hide the draught cords ("fils con-
ducteurs") of the cording.
The toothed wheel a set on the horizontal shaft, at the end of which is
the crank b, serves for the transmission of the motive power (Fig. 1,
Sheet I.).
The grooved connecting rod c obeys the crank to produce the lowering
of the marche (" contre-marche") d by its passage over the end thereof.
This connection rod is guided by a fixed pin passing into the groove at
the point c'. The drawing of this rod represents two of the positions
which it occupies during its action upon the marche (Fig. 1, Sheet I.).
The treadle A. receives its motion from the marche d by the end which
comes beneath it.
It will be understood that the treadle A as well as the marches & must
have one end set upon pivots to produce the effect of levers, drawing
towards them all the resistances of the loom.

page_text: •
The roller B receives a rotary motion by its connection with the
treadle A (see Sheets II. and III., Fig. 1).
•
Motion is given to the roller C placed at the upper part of the loom,
and from thence to the part termed the grif or lifting bar of a cording
or simple jacquard mechanism D (see Figures 1, Sheets I. and III.).
As nearly all the effects produced in the loom depend upon the
. functions of this cording, it is necessary to explain its mechanism, which
will naturally lead to a knowledge of these effects.
The lifting wires, which are twelve in number, are fork-shaped, as
may be seen at Fig. 2, Sheet III. The hind branch bearing against a
rod at the top and held below by a heddle hook ("passette") forms
spring, so that the main branch may join the cylinder Ox, which actuates
it by small notches at the moment when it is to work.
The main branches of the lifting wires Nos. 1, 2, 3, 4, 5, 6, 9, and 10,
have the shape of actual hooks. Those Nos. 7 and 8 are straight,
because they are driven back instead of being lifted off. Those of
Nos. 11 and 12 are bent over to square in order that they may escape at
half course by the aid of a tie ("attache"), which regulates their journey
(see Fig. 2, Sheet III.). Each of these lifting wires is provided with
a small spring, which draws it back by the lower part. The Nos. 5 and 1
6 have one at each end; that at the upper part is more powerful than
the other in order that the lifting wire may always rise again after
accomplishing its work.
The cylinder Ox is shown in its place at Fig. 1, Sheet III., and on its
four sides Fig. 3, same Sheet. The Drawing shows that the small notches
in coming before the lifting wires by the rotation produced by the catch
("clichet") *P, *P, (Shect III., Fig. 1) at each elevation of the grif,
permits the lifting wires to work at the proper time. In presenting
these notches to the lifting wires the cylinder Ox actuates the first face,
the Nos. 1, 4, 8, 9, 10, and 11, for the gauze treadle or gauze shed (“pas 3
de gaze"); the second face, the Nos. 1, 5, 7, 8, and 11, for the figuring
treadle or figuring shed ("pas de broché"); the third face, the Nos. 2,
3, 4, and 12, for the heavy treadle or heavy shed ("pas dur"); the
fourth face, the Nos. 2, 6, 7, 8, and 12, for the figuring treadle or shed
("pas de broché ").
To thoroughly define the preceding, I will now follow the progress of.
the effects produced by each separate lifting wire.

page_text: The 1st and 2nd lifting wires pull by cords or by metal rods the large
catches ("clichets") Q, Q, which take the slanting position Q, Q',
permitting the escape of the cross pieces R, R, which fall to R', R¹, by
means of the weights attached to them (see Fig. 1, Sheet I., and Fig. 1*
Sheet II.). These movements take place at the moment when the
roller C permits the slackening of the cords passing over U, U. These
movements cause the swinging of the pieces S, S, which place themselves
at S¹, S¹, so as to draw sharply the whips ("fouets") T to T¹ by the aid
of the cords passing over the pulleys X*. These whips, furnished with
peckers ("taquets"),.drive the shuttles from one end of the batten to
the other. The two lifting wires act alternately, the 1st. on the right,
and the 2nd on the left side.
The 3rd lifting wire lowers the 2nd lifting blade ("lame") by the aid
of the "cooper" ("bricoteau") E. This 2nd lifting blade lifts the 1st
by the communication of the cords passing over a small roller g. This is
what produces the hard treadle or hard shed ("pas dur").
The 4th lifting wire lifts the boxes of the batten M by the cords
which connect it with the "cooper" P, the roller O, and, boxes N. This
movement is regulated by the piece Z' (Fig. 1, Sheet I., and Fig. 1,
Sheet II.), which is attached to the cord passing from the 4th lifting
wire to the "cooper" P. This piece Z rises at the same time as this
cord, and stops at the position Z" upon a catch ("clichet") Z (Figures 1
and 4, Sheet III.) to keep the boxes suspended during the passage of
the shuttles. This passage accomplished, the boxes fall again by the
release of the catch Z, effected by the cord on the roller C, aided by the
small roller Ź* (Figures 1 and 4, Sheet III.).
The 5th and 6th lifting wires work inversely to the others, they are
driven back by the "grif" instead of being carried off. They com-
municate by means of the small pulleys r, and of a ring placed at the
lower part of the batten on the right side with the jointed part of a slide n
(Fig. 1, Sheet I., and Figures 1, 5, and 6, Sheet III.). The operation of
these lifting wires combines with that of the two forks placed at cach
end of the slay ("peigne "), as may be seen Fig. 1, Sheet I., and better
at Figures 5 and 6, Sheet III., where they are seen from above. This
3 combination leaves the weft free action in the fork, so that when the
shoot breaks, this fork being no longer upheld in line with the slay, the
slide n drawn by its spring assumes an upright position, coming against

page_text: the batten, as may be seen Fig. 6, Sheet III. The shock thus produced
pushes the movable part of the marchic d¹ (see Fig. 6, Sheet III.), which
places it out of reach of the rod c by the shifting of the piece l, which
goes to , stopping the loom. This stoppage continues until the catch
("clichet"), which had fallen to d by the pulling of a spring, is
raised by a spcoial cord, and permits the marche to resume its straight
position, as shown Fig. 5, Sheet III.
The 7th lifting wire actuates the jacquard mechanism X by means of
the cords attached to the slays ("balanciers") F and V, see Fig. 1,
Sheets I. and II.
The 8th and 9th lifting wires operate the "cooper "f, which by its
fastenings ("attaches) releases the back short arm or lever ("courts-
bras") o¹ (Fig. 1, Sheet II.), at the moment of the passage of the gauze
and figuring sheds ("pas de gaze et de broché"). There are here 2
lifting wires for the same object, because for the "broché" shed the
short arm must lower more than for the other. ⚫
•
The 10th lifting wire lowers the 4th lifting blade ("lame") by means
of the "cooper" G. This lifting blade causes the 3rd to rise by the aid
of the 2nd roller g¹ (see Fig. 1, Sheet II.). These two operations
produce the gauze shed ("pas de gaze").
It has not been possible to draw upon Sheet I. more than one lifting
bar ("lame") to show the place occupied by them and their short levers
("courts-bras"), but at Fig. 1, Sheet II., these lifting bars are drawn
and numbered from 1 to 4 and the short levers are marked a, o'.
The 11th and 12th lifting wires communicate with two small catchies
("clichets ") placed on each upright of the batten, between the boxes N
and the slay ("peigne"), (see Fig. 1 of cach of the 3 Sheets of
Drawing). These small catches serve as stops to two small hinged
rods m through which they pass. At the lower end of these rods are
cords which pass behind the batten and communicate with two other
larger slotted or sliding catches ("clichets à coulisses ") i, i, placed in
the middle of the loom on each side of the treadle A. This com-
munication takes place by means of cords and small rollers t, u, v* (scc
Figures 1, Sheets I. and III., and Figures 1, 2, 3, 4, Sheet II.). The
Figure 2, Sheet II., represents a portion of the batten seen from behind
to show the position of the draught threads ("fils conducteurs ") and of
their rollers t, u.

page_text: The two catches i, i, have slots ("coulisses") in order that if the
shuttle should diverge or remain in the shed ("pas") the loom shall be
instantaneously stopped. In this case the catclics i, i, are lifted by the
treadle A with which they gear, and give motion to a hook or catch k,
which in taking the position ¹, actuates the marche d', placing its end
outside the course of the connecting rod c. This displacement of the
movable part of the marche is facilitated by the pieces h, which are
drawn to with it.
To complete the explanation of these somewhat complicated move-
ments it is desirable to state that the action of the lifting wires 11 and
12 is combined with the draught ("passages") of the shuttle ("navette"),
so as to leave to this latter all its action upon the draught of the
catches i,, that is to say, that on the side upon which the shuttle does
not act the opposite lifting wire replaces it, so that as long as the loom
works regularly these catches i, i, are in the position shown Fig. 1,
Sheet I., and Fig. 3, Sheet II. Directly the shuttle misses its stroke
these catches i, i, place themselves as shown, Fig. 2, Sheet II. This
latter explanation applies also to the lifting wires 5 and 6 for their
alternate action with the shoot acting in the forks.
After this long description, which should cause the action of the loom
to be thoroughly understood, there remains only to set forth the move-
ments of the batten M, which alone are outside of the action of the
lifting wires of the cording.
The lever H attached to the treadle A communicates by means of a
pulley K with two rods I, which are united in the middle of the loom
by a pivot or bolt fixed in the batten M, so that at each movement of the
treadle A, a recoil motion takes place following the first position of the
picce I, Fig. 2, Sheet I. Directly the treadle A rises again, the batten
again comes forward by the action of the weight J on the piece I, aided
by the pulley L. This forward movement produces the action known as
milling ("draper"); at this moment the position of the piece I is
advanced, as shown at I', Fig. 2, Sheet I.
The frame of the loom is not completely drawn, nor the supports of
the various "coopers" ("bricoteaux"), rollers, pulleys, and accessaries,
in order not to further complicate the lines of the Drawing. This insig-
nificant want can be casily supplied.

page_text: The recall of the cylinders of the "jacquard" and of the cording, as
well as the freeing of the hook or catches d", d, take place as usual by
cords placed according to the pleasure of the weaver.
All the springs are spiral shaped and of slight brass wire, excepting
that of the see-saw or swing y, y, which works with the "grif," which 5
requires to be stronger, because after being shifted to y, y', by the
roller C, its spring must make a somewhat powerful effort to assist this
roller in lifting the cross pieces R and their weights R¹ (see Fig. 1,
Sheet I., and Figures 1 and 1*, Sheet III.).
In witness whereof, I, the said William Edward Gedge, have here- 1
unto set my hand and seal, this Seventh day of December, in the
year of our Lord One thousand eight hundred and seventy-two.
