Islands of Jersey, Guernsey, Alderney, Sark and Man, and also in all Her
said Majesty's Colonies and Plantations abroad, my Invention of "CERTAIN
IMPROVEMENTS IN WEAVING;" in which said Letters Patent is contained a proviso
obliging me, the said James Brown, to particularly describe and ascertain the
nature of my said Invention, and in what manner the same is to be performed,
by an instrument in writing under my hand and seal, and fo cause. the same
to be enrolled 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,.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
James Brown, do hereby declare the nature of my said Invention, and the
manner in which the same is to be performed and carried into practical effect,
to be as the same are described and ascertained in and by the following
statement thereof, reference being had to the four illustrative Drawings
hereunto annexed, and to the figures and letters marked thereon, that is to
say:
My Invention of Certain Improvements in Weaving is applicable to that
description of weaving called ribbon weaving, and plain and figure weaving of
any description, and consists,-
Firstly, in forming the ground only of brocaded work by the use of one
shuttle.
And, secondly, the weaving of plain goods, such as checks, tartans, &c.,
without the use of any shuttle.
And, thirdly, the use of revolving races or shuttle carriers.
And, fourthly, of an improved method of raising and lowering the sliding
plank of the batten of double batten looms, and imparting motion to the
shuttles by the action of the Jacquard machine.
And, fifthly, an improved method of connecting shuttles to the battens of
looms.
And in order to explain my said Invention as completely as possible, I will
proceed to describe the means by which I carry my said Invention into
effect.

the mode of actuating the same and driving the shuttles. Figure 12 is
an end view of the batten and parts in connection therewith. Figure 13 is a
transverse and vertical section thereof, taken through the line E, F, at the
Figure 11 in the Drawing No: 3. Figure 13* represents a transverse and
vertical section of the framing of a double-batten loom, shewing some of the
before-mentioned improvements applied thereto. Figure 14 exhibits a side
elevation of the arrangements to be employed for driving the shuttles. Figures
15 and 16 are end views of the said arrangement looking at the back of the
loom. Figure 17 is a top plan view of the above arrangement. Similar
letters of reference are placed upon and denote corresponding parts, in so far
as such parts appear or can be seen at each of the Figures respectively. At
the Drawings No. 1, A, A, marks the framing of the loom, to the upper part
of which is fixed the Jacquard machine B, which is worked in the usual way.
C, C', mark swords, to the lower ends of which is fixed the batten D, which
is suspended thereby from bearings E, fixed to the upper part of the framing,
as shewn at Figures 2 and 3. F marks the harness of the loom. G the
driving pulley fixed upon one end of the axle H, which axle extends across
the entire width of the loom, and is mounted in suitable bearings at each end
thereof. I, I, mark levers of the first order, having their fulcra upon pins or
studs a, fixed to the upper part of the framing, as shewn at Figure 1. These
levers are connected together at their extremities, in order that they may
act simultaneously, and from three of these levers there extend vertical rods
K, K, the lower ends of which pass through the upper part of the batten.
These rods are connected to a sliding bar L, placed at the front of the batten,
such bar extending across the width of the said batten. M marks needles
placed at certain distances asunder, and connected to the bar L by thumb
screws b, b, the said needles being employed for the purpose hereafter men-
tioned: N; N, mark the reeds through which the warp threads and brocading
threads pass. 0, 0, mark pieces of metal fixed to the front of the batten.
One of such pieces is shewn at Figure 5. In this piece of metal there is
formed a slot c, c, in which works the plain part or barrel of a screw d, d, to
which screw there is .connected one end of a piece or fork P, which moves
upon.a fulcrum at e, which is a rivet for connecting the said piece to the piece
Q, which last-mentioned piece actuates the piece P by means of the traversing
bar R, to which it is fixed, the said bar being put in motion by the arrange-
ment hereafter described... S, S, mark brocading threads of different colours,
passing through leises in the harness, such threads being placed parallel to
°

page_text: and by the side of the warp threads. The harness through which the said
brocading and warp threads pass is in immediate connection with the Jacquard
apparatus, and is acted upon by it according to the pattern required, and
according to the arrangement of the cards of the said Jacquard employed for
effecting the shed of the brocading and warp threads. Now as the circum-
stance of thus arranging and disposing the warp threads and effecting the
shed is in common use, and well known to every practical weaver, I therefore
desire it to be distinctly understood that the peculiar feature of this part
of my said Invention consists in arranging the different-colored brocading
threads which are to form the pattern in a similar manner to and by the side
of the ordinary warp threads employed for forming the ground of the work,
by which arrangement the necessity of employing more than one' shuttle
for the purpose of weaving patterns composed of several colours is entirely.
dispensed with.
I will now describe the means by which I effect the shoot or carry the
brocading threads either partly or entirely across the width of the ribbon under
process of weaving. For example, suppose it is required to form a pattern at
one selvage, and of about one third of the entire width of the ribbon, so as to
leave the other part or ground of the work plain, the same may be effected by
the forks P and Q, shewn at Figure 5 of Drawing No. 1, the action of
which is as follows:-The bar R, to which the piece Q is fixed, receives
reciprocating movement by the alternate circular motion of the pulleys Z, Z,
such said pulleys being connected to the said bar in a similar manner to those
now in use for working the shuttle bars and pecks which drive the shuttles in
ordinary ribbon looms; and as one or other of the brocading threads is raised
by the hooks of the Jacquard machine, and the bar R receives motion in the
direction of the arrow, the part P* as it descends the inclined portion of the
groove c will seize the brocading thread intended to be used, and carry it across
the face of the reed N, when the needle bar R and needles M, being caused to
descend by the means hereafter described, the said needles will retain such
brocading thread in the proper position until the fork P has been returned to
its original position and the shed has been effected, after which the bar and
needles will be raised by the means hereafter described, and the subsequent
operation of beating up be effected in the usual manner. The arrangement
employed for determining the distance to which the needles which hold the
brocading threads are to be moved to produce the required pattern is repre-
sented at Figures 9, 10, 10* of Drawing No. 2, where A¹ marks a framing, at
the upper part of which there are fixed planks B¹, C', such planks being per-
forated with holes D¹, E¹. The holes E¹ are furnished with a series of pegs or

page_text: pins F¹, the lower ends of which pass beyond the under surface of the under
part of the framing A', and to the upper ends of the said pegs or pins there
are attached cords G', which pass through the holes formed in the plank B',
and the said cords pass from thence to the hooks of the Jacquard machine, to
which they are made fast, and by which they are put in motion. H', I', mark
sliding bars attached to the framing A¹ by screws K¹ passing through slots
formed in the said bars, as shewn. L' marks a lever of the first order for
connecting together the said bars. M¹ marks a screw or pin attached to the
framing, such screw or pin being the fulcrum of the lever L'. To the top
sliding bar H¹ there is fixed a stop or projection N¹, shewn at Figures 10 and.
10*, which extends across the under surface of the upper part of the framing,
such stop or projection being for the purpose of determining the distance to
which the sliding bars H', I', are moved. O¹ marks a sliding bar, which is
connected to the bar I¹ by guide pins P¹, which allow the said bar to move
both vertically and horizontally, and to this bar the needles M before mentioned
are fixed and move therewith. Q¹ marks a helical spring, one end of which
is fixed to the framing, and the other end to the sliding bar H', for the purpose
of returning the said bar.and parts in connection therewith to their original
position. Now suppose this apparatus or arrangement of parts at the com-
mencement of the operation of weaving to be in the position shewn, it will
appear evident that in order to pull the bar H' in the direction of the arrow,
the stop N¹ must be first disengaged from one or other of the pegs or pins E'
which arrest it; and this is effected by the action of the hooks of the Jacquard
raising one or more of the said pegs or pins, according as the cards are
pierced, to suit the required pattern, by which the needles M will made to
pass through variable distances from the selvage of the work. For example,
let the Diagram Figure 10** represent the entire width of a ribbon upon
which it is required to form a pattern,, the width of which is represented by
the lines 1, 2, 3, 4, and of the shape there shewn, the distance through
which the needles must move to produce that portion of the pattern between
1 and 2 will be determined by the action of the Jacquard upon the pegs or
pins E', which being lifted by it will allow the stop N' and sliding bar H' to
which the said stop is attached to be drawn to the required distance, when
the elasticity of the helical spring Q¹ will place the bar in a proper position to
be again acted upon for producing that portion of the pattern between 2 and 3,
which will be effected by the Jacquard lifting a greater number of the pegs or
pins E¹, so as to allow the bar H', and needles which are in connection there-
with, to have a longer range, in accordance with the configuration of the pattern
and the action of the Jacquard upon one or other of the said pegs or pins..

page_text: And I would remark, that in weaving ribbons the pattern of which is required
to extend in the direction of each selvage, so as to leave the centre portion of
the ribbon plain; the same may be effected by employing a similar arrange-
ment of needles and forks upon the opposite selväge of the ribbon under
process of weaving, and each such arrangement of .the said needles and forks
may either be caused to act simultaneously or alternately by the arrangement
above described. For example, suppose the patterns at each selvage to be
similar, but irregularly arranged, as represented by the Diagram at Figure
10*** of Drawing No. 2, it will appear evident that in this particular instance
the needles and forks which are opposite to each other will be required to act
alternately, the shuttle being employed to form the ground of the work; but if
the patterns at each selvage were opposite, then the needles would be required
to act simultaneously. The means employed for lifting and lowering the bar
L, shewn at Drawing No. 1, and needles attached thereto, is as follows:-
Upon the sword C¹ there are fixed the castings T, which support and guide a
system of tappets marked U, V, W, X, as shewn at Figure 6 of Drawing No. 1,
such said tappets receiving and imparting motion by the following mechanical
arrangements: At the Figure 3 of Drawing No. 1, Y marks a lever, having
its fulcrum upon a pin Z, passing through holes in the casting f, fixed to the
framing of the loom. H marks the crank shaft, which may be driven by any
suitable prime mover. Upon one part of the said shaft there is keyed a cam g,
which, as the crank shaft revolves, comes into contact with an antifriction roller h
attached to the lever Y, by which one end thereof will be depressed, and
thereby impart motion to the rod i, which is attached thereto. The upper end
of the said rod is attached to one end of a lever k, the fulcrum of which is
upon a pin l, and to the opposite end of the said lever and at each side thereof
there are attached two rods or bars m, the lower extremities of which are
connected to the rods n; and upon each of these rods there is fixed a hook-
shaped piece o for imparting motion to the tappets V and X, the hooked part
of such said tappets being made to lock or take into the hooked portion of the
pieces o, o, in the following manner :-The tappets V, W, being connected to
the Jacquard machine by the cords p will receive motion therefrom, and the
inclined portions 7 of the said tappets acting against the corresponding inclines
upon the tappets V and X, will have the effect of pushing these last-men-
tioned tappets over the hooked part of the pieces o, by which, as one or other
of the said pieces is raised, it will impart motion to the said tappet, and such
motion will be transmitted to the levers I, I, through the medium of the rod m',
which is connected thereto, by which the necessary lifting of the needles will be
effected for releasing the brocading threads at each shed of the warp threads.

page_text: And I would remark, that in weaving that description of ribbons called checks
and tartans the use of the shuttle may be dispensed with, as also the arrange-
ment for determining the distance through which the needles move, the fork P
performing the office of the shuttle in the manner before described. The
operations of the revolving shuttle carrier, and parts in connection therewith,
shewn at Figures 11, 12, 13, of Drawing No. 2, are as follows:-A³, A³,
mark the batten of the loom, to the front part of which there are fixed the
brackets B. These brackets support the rod C2, which revolves freely in
holes formed in the said brackets, and upon this rod, which extends the entire
length of the batten, are fixed the shuttle carriers or supports D, upon which
are formed the races E2 for connecting the shuttles F2 thereto, and guiding
them in their proper course for effecting the shoot. The means employed for
imparting motion to the shuttle carriers or supports D are as follow:-Upon
one end of the rod C² there is fixed the piece G2; to this piece there are fixed
the pins 1, 2, 3, 4, and upon the upper part of the pins 1 and 2 there rests
the piece H, which is for the purpose of retaining the shuttle carriers or
supports and shuttles in the proper position for effecting the shoot. .12, K2,
mark tappets working through guide holes formed in the castings L, which
castings are fixed to the front and at the end of the batten, as shewn.
M², M², mark tappets for throwing the hooked ends 5 and 6 of the tappets
I, K2, simultaneously into gear with the hooked piece. N%, and one or other of
the pins 1, 2, 3, 4. O marks a hollow cylindrical guide piece fixed to the
upper casting L. Within this guide piece there is placed a helical spring.
which presses upon the upper and cylindrical portion of the piece H², by which
the said piece is guided in its proper course, and the elasticity of the helical
spring keeps the lower part of the piece H2 in close contact with any two of
the pins 1, 2, 3, 4, by which the piece G2 and the shuttle and shuttle carriers
or supports are prevented from turning except at will. The springs P² are for
the purpose of disengaging the hooked parts 5 and 6 of the tappets I², K²,
from the pins and hooked piece N2, when such parts are not required to be
acted upon. Q, Q, mark cords attached to the tappets M², such cords being
connected at their upper extremities to the hooks of the Jacquard machine by
which they are acted upon. R* marks the lower portion of a connecting rod
for imparting motion to the piece N2, to which it is attached, and I employ.a
similar arrangement to that shewn and described at Figure 3 of Drawing
No. 1 for imparting motion to the said rod and parts in connection therewith.
S, T, mark rods extending across the front of the batten, to which they are
connected by pieces v, in which they have free liberty of movement in a
circular and horizontal direction; and upon the rods S2 and T2 there are fixed
3

page_text: at certain distances asunder the forked levers V2, which are for the purpose of
driving the shuttles. The upper forked levers being brought over the pins 7,
fixed to the shuttles, carry them forward, and the lower forked levers being
brought over the pins 8 take them back. It should be observed this mode of
working the shuttle carriers can only be used when two shuttles are required
to work backwards and forwards in regular succession; and when the shuttles
are required to work in regular succession the same may be effected in the
following manner:-At Figures 22 and 23 of Drawing No. 4, A5, B5, C³,
mark a train of wheels of different diameters; that marked A³ is keyed upon
the end of the rod D³, upon which the shuttle carriers are mounted, and the
wheels B, C, which are mounted in bearings, as shewn, gear or take into the
wheel or pinion A5. E, E, mark circulate plates of metal fixed upon the
rod D, and between these plates there are pins F³, arranged or disposed at
certain equal distances asunder, such pins being employed for a similar purpose
to that before described and represented at Figures 11 and 12 of Drawing No. 2,
and are likewise similarly acted upon by the hooked piece and tappets there
shewn; the same letters of reference are therefore employed to denote cor-
responding parts. And to each of the wheels B³, C³, there is fixed a similar
arrangement of plates, pins, hooked pieces and tappets to that shewn and
described with reference to the wheel or pinion A³. The means employed for
imparting motion to the said hooked piece, tappets, and wheels, is represented
at Figures 24, 25, 26, 27, 28, and 29. Upon one end of the crank shaft G
of the loom there is fixed an excentric H5, to which is connected the lower
end of an excentric rod I. The upper end of the said rod is connected to a
lever K, whose fulcrum is upon a pin or stud Lo, fixed to the top of the
framing of the loom, as shewn, and to the other end of the lever K³ there are
fixed the upper ends of three rods M, N, O, the lower ends of the said rods
being severally connected to the hooked pieces N2 (shewn at Figure 22), by
which the rods M, N, O, and hooked pieces N will be simultaneously acted
upon, and by raising one or other of the tappets by the hooks of the Jacquard
machine, to which they are connected by cords in accordance with the
required pattern, in like manner with one or other of the wheels A5, B5, C5,
receive motion and impart it to the rod D³, and shuttle carries thereon in the
following ratio:-The difference between the diameters of the wheels A³ and B
is such that when the wheel B' is acted upon by the tappets it will cause two
sides of the shuttle carrier to be advanced, and the difference between the
wheels A and C is such that when the wheel C³ is acted upon it will cause
three sides of the shuttle carrier to be advanced. For example, let 1, 2, 3, 4,
at the Figure 24 of Drawing No. 4, represent the four shuttles. In order to

page_text: turn the shuttle carrier from 1 to 2, the tappets 12 or K2 must be acted upon
by the Jacquard machine, by which the hinged lifting piece 6 of the tappets
will advance the wheel A³ the required distance to produce the desired result.
When it is required to move the shuttle carrier from 1 to 3 the same may be
effected by causing the tappets I³, K2, to be acted upon, by which the hinged
piece 6 of these tappets will advance the wheel B', and thereby imparts
motion to the wheel or pinion A, by which the desired result will be
attained. To move the shuttle carrier from 1 to 4 the tappets in con-
nection with the wheel C5 must be acted upon in a similar manner. And
I would remark, that as only one of these sets of tappets can ever be
in action at one and the same time, the order in which one or other
of such tappets is brought into action so as to produce a variable number
of turns of the shuttle carriers, will depend upon the arrangement of
the cards in the Jacquard machine, which must be in accordance with the
required pattern. The tappets at the opposite side of the hooked pieces
N are for the purpose of reversing the direction in which the shuttle car-
riers turn,. as before described and referred to with reference to Figure 12
of Drawing No. 2. The means employed for imparting motion to the shuttle
drivers are the same as those now in use for that purpose, but the arrange-
ment necessary for keeping the drivers back when the shuttle carriers have to
turn is as follows:-A, B, C, D, mark levers, having their fulcra upon pins
in castings fixed to the framing of the loom. To the opposite ends of these
levers there are connected the lower ends of rods E, and the upper ends of
these rods are connected to one end of each of the levers F, G, H, I, which
have their fulcra upon pins K passing through castings L', situate at the top
of the framing of the loom, as shewn. M, N, O, P, mark rods or bars, the
upper ends of which are connected to the levers F, G, H, I, and to the
levers F, I, there are attached rollers Q, R (shewn at Figure 24), for
the purpose hereafter described, and upon the levers G, H, there are formed
projections or inclined planes S, T, for the purpose hereafter described.
U, V, mark bent levers fixed upon the upper rods or bars W, as shewn at
Figure 24, and X, Y, mark bent levers fixed upon the lower rods or
bars Z, shewn at the same. Figure, and these bent levers are operated
upon in the following manner: - Upon the crank shaft G³ there are
placed a series of cams A, B, C, D, E, (shewn in plain view at
Figure 27) which are connected together, and such cams slide upon a feather
in the crank shaft in a precisely similar manner to that before described and
represented at Figures 15 and 17 of Drawing No. 3; and as one or other of
the pieces Q, R³, is acted upon by the Jacquard machine, in like manner will.

page_text: the cams be moved from right to left and left to right when the pieces Q³, R³,
.are acted upon, by which the cams B', D', will be made to act upon the levers
A, D, rods E, levers F, Iº, and rod or bar M, Po; and these rods or bars
being thus raised into the position shewn at Figure 24 they will push forward
the bent levers U, V, during the time that the shuttle carriers are being
turned; after which the cam C' is made to. act upon one or other of the rods
or bars N, 0°, which as they are raised will disengage the projections or
inclined planes S, T, from the bent levers U, V, by which the drivers will
be brought over the pins on the shuttle, when they will be driven by similar
means to those now employed in looms for ribbon weaving. The forked
levers V are for the purpose of carrying the shuttles partly across the space,
and the forked levers V* are for the purpose of carrying them through the
remaining distance. It should be observed, that the lower ends of the rods or
bars M, N, O, P, (shewn at Figure 24) are formed with pulleys Q, R6, and
projections S, T, thereon, the effect of which is to throw one set of drivers out
of action when the others are required to act, or, in other words, to act
alternately upon the upper and lower drivers. The rollers Q, Ro, upon
the levers M, P, are for the purpose of throwing all the drivers simultaneously
out of use when the shuttle carriers are to be turned round, in accordance
with the required pattern. The mode of arranging the warp threads, affecting
the shed, beating up the weft, and the remaining operations incidental to
ribbon weaving, are the same as those now in use.
Now it will appear
evident that if the cord Q³× (shewn at Figure 22) be pulled it will raise the
tappet M³, and thereby cause the hooked portions 5 and. 6 of the tappet I'
to be brought into contact with the hooked end of the piece N² and pin 3,
and the piece N2 being raised by the means before described will likewise
raise the tappet 12, and move the pins 1 and 3 into the position previously
occupied by the pins 1 and 2, by which another shuttle containing weft of a
different color to the last will supply the place of the former shuttle, and this
mode of action applies to each of the four shuttles. In order to turn the
shuttle carrier or support in the contrary direction there is another and
similar arrangement of tappets at the other side of the piece G². Thus as one
or other of the cords Q and Q2* are pulled by the action of the Jacquard
machine, in like manner will be presented different colored weft for the shoot,
in accordance with the required pattern. The improvements represented at
Figures 13, 14, 15, 16, 17, of Drawing No. 3, for raising and lowering the
sliding plank of the batten. of double-batten looms is as follows:-A³ marks
the framing of the loom, to the front part of which there is attached one.end
of, a lever B³, by a pin C³, which is the fulcrum thereof, and to the opposite

page_text: end of the said lever there is connected one end of a rod D³, the upper
extremity of which said rod is connected to one end of a lever E³, the fulcrum
of which is upon a pin F³, and to the opposite end of the said lever there is
attached one end of a rod G3, the lower end of which is attached to the
sliding plank H³, of the batten 13. K³ marks the crank shaft, upon which is
fixed a cam Ls, which, as the said crank shaft revolves comes into contact
with an antifriction pulley M³, which is attached to the lever as shewn, and
by which the said sliding plank and shuttles are raised; and as the larger.
diameter of the said cam recedes from the antifriction pulley M³, the weight
of the sliding plank H³ causes it to descend together with the shuttles; and
in order that the motion of the shuttles may be in accordance with the
raising and lowering of the sliding plank and pattern to be produced, I employ
the following arrangement:-Upon the crank shaft K³ there is placed a
cam N³, which slides upon a feather in the said shaft, and at each end of the
boss of the said cam, and upon the said crank shaft, there are placed cams
03, P3, which have likewise liberty of motion upon the crank shaft K³ by
the feather therein. Q³, R³, mark tappets working through guides formed in
the casting S³, as shewn at Figure 17, such said casting being supported by
the standards T. U³ marks the lever, the fulcrum of which is upon a pin V³,
and to each end of the said lever the lower ends of the tappets Q3, R³, are
connected as shewn. W³, W³, mark pins passing through slots formed in
the said tappets for guiding them in their proper course. X3, X3, mark cords
which are attached to the upper ends of the tappets Q3, R3, such said cords
and tappets being put in motion by the action of the Jacquard machine.
Z3, Z3, mark vibrating levers suspended from a rod A', which is the fulcrum
thereof, the said rod being fixed to the framing of the loom, and to the
lower end of each of the said vibrating levers there 'are connecting cords B*,
which pass over guide pulleys C, and from thence to the pulleys D, E, to
which they are fixed, for imparting motion to the shuttles, which is effected in
the following manner :-Suppose the tappets Q³, R³, and cams N³, 0³, P³, to
be in the position shewn, it will appear evident that as the crank shaft
revolves in the direction of the arrow, the cam 0³, coming into contact with
the projection I³, formed upon the tappet R³, will cause the said cam, as also
the cams N3, P3, to be moved upon the crank shaft in the direction of the
arrow; and the said cams will be moved in a contrary direction by the
Jacquard machine pulling up the tappet R³, which will depress the tappet Q³;
and as the cam P³ comes into. contact with the projection. Is of the tappet Q³,
this cam, as also the cams N³, 03, will be pushed in the opposite direction,
and this reciprocating movement of the cams will cause the cam N³ to act
°

page_text: alternately upon the pulleys F4, and the vibrating levers Z³, to which they
are attached, by which the cords B', and pulleys D', E', will be alternately
pulled in opposite directions, and thereby effect the driving of the shuttles,
the said pulleys being connected to the shuttles in the ordinary manner.
Having now described the nature of my said Invention, and in what manner
the same is to be performed and carried into practical effect, I desire it to be
distinctly understood that I claim,-
Firstly, the weaving brocaded or figured fabrics with one shuttle, by
arranging the different coloured threads to be employed for producing the
pattern by the side of and parallel to the warp threads, each of such brocading
and warp threads passing from the rollers upon which such threads are
wound through the leishes of the harness, and from thence between the spaces
of the reed to the work roller, such brocading threads being severally acted
upon by the hooks of the Jacquard machine to which the harness of the loom.
is connected, and the carrying the said brocading threads partially or entirely
across the ribbon or other fabric, in accordance with the required pattern, as
herein-before described and set forth.
Secondly, the weaving of plain goods, such as checks, tartans, &c., without
the use of any shuttle, by arranging the different coloured threads to
be employed by the side of and parallel to the warp threads, each of such
warp threads passing from the rollers upon which such threads are wound
through the leishes of the harness, and from thence between the spaces of
the reed to the work roller, such threads being severally acted upon by the
hooks of the Jacquard machine to which the harness of the loom is connected,
and the carrying the said threads partially or entirely across the ribbon in
accordance with the required pattern, as herein-before described and set forth.
Thirdly, the use of revolving races or shuttle carriers, constructed and
worked as herein-before described.
Fourthly, the improved method of raising and lowering the sliding plank
of the batten of the ordinary double batten loom, and imparting motion to
the shuttles through the action of the Jacquard machine, as herein-before
described.
Fifthly and lastly, the connecting shuttles to the battens of looms and
dispensing with the top plank, in the manner herein-before described.
In witness whereof, I, the said James Brown, have hereunto set my

Lord One thousand eight hundred and forty-six.
