my Invention of "IMPROVEMENTS IN LOOMS FOR WEAVING RIBBONS AND OTHER
FABRICS;" in which said Letters Patent is, contained a proviso, that. I, the
said Thomas Robinson, should cause a particular, description, of 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, to be inrolled in Her Majesty's
High Court of Chancery within, six: calendar months next and immediately.

page_text: after the date of the said in part recited Letters Patent, as in and by the same,
reference being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Thomas Robinson, do hereby declare that the nature of my Invention,
and the manner in which the same is to be performed, are particularly
described and ascertained in and by the following statement thereof, refer-
ence being had to the Drawings hereunto annexed, and to the figures and
letters marked thereon, that is to say :-
The first part of my Invention consists of an improved arrangement and
construction of those parts of the loom known as the batten breast piece and
back roll, whereby a much greater number of pieces may be woven in a
loom wherein the shuttles are driven by pegs than can be woven in a similar
loom of the ordinary construction, and also in a new and improved method of
communicating the motion from the shaft of the loom to the slide which
actuates the shuttles. The arrangement of the batten is such that the shuttles
are placed in two planes one above the other, so that the shuttles of
the bottom row shall be when at rest under the ribbons of the top row,
and the shuttles of the top row will be by consequence over the ribbons
of the bottom row, as may be seen by reference to Drawing No. 1,
which presents a front view of the batten. The shuttles are of the form
generally in use in power looms, and move in planks or slides in the usual
way; but in order to obtain the two rows or sets one above the other
I use three of these planks or slides, videlicet, the top, middle, and bottom
plank, marked respectively a, b, c. The top and bottom planks are of the
usual form, and the bottom one is fixed to the bed or block of the batten
with wood screws. The middle plank is of box or other hard wood, and
is of the peculiar form shewn in the Drawing, where it will be seen that it
is notched or spaced out on the under side, as at d, to form the upper part of
the space for the ribbons on the bottom row, and also notched or spaced out
on the top side, as at e, to form the lower part of the space for the ribbons in
the top row. The mode of fixing this middle plank is by screw pins with flat
round heads, shewn at f, Figures 1 and 2, passed through the plank at every
interval between the spaces, and through upright pieces of wood called
poppets, 9, 9, morticed at proper intervals into the bed of the batten, which
pins are fastened at the back with a thumb nut. The middle plank is of such a
width that the grooves for the top and bottom sets of shuttles to work in shall
be two inches and one-eighth apart from centre to centre, and it may be put on
in any number of lengths or pieces, as most convenient; but it is very desirable
that the ends of the separate pieces should come together in a bottom space,

page_text: as seen at h, Figure 1, as by this means the top set of shuttles will all have a
plank to work upon, without a joining falling in any one of them. Each
separate piece of this plank has also two or more wire pegs or steady pins
passed through it, as at i, i, and driven tight into the upright poppets, the
object of these pegs being to secure the correct position of the planks being
obtained again after they have been taken off for the purpose of being cleaned.
The top plank is also fixed to the upright pieces 9 by screw pins and thumb
nuts, the heads of the pins being let into the front of the plank level with its
surface, as at a, in order that the drivers or slides j, j, may move freely
without obstruction. This top plank may be most conveniently put on in
lengths embracing two or three spaces in the top row, according to the width
of the spaces. The upright pieces 9 are notched out to make room for the
back part of the shuttles, as will be seen in the Drawing No. 2, at x, x.
The block or bed of the batten is notched or spaced down at proper intervals,
to form the lower portion of the spaces in the bottom row, as will be seen at
k, k, Figure 1, where a portion of the framework is shewn by removing the
planks and drivers, and this is done in order that the bottoms of the slays.
in both rows may rest upon the bed itself, and not depend upon the poppets..
By this means the batten is much stronger, and capable of making much
heavier work without risk of any part giving way. The slays are fixed by
placing the top end in a brass, such as is well known, and the bottom end is
secured with a slay hook and block in the usual way. The bottom drivers
10, 10, move or slide upon brasses of the form shewn in Figures 3, 3b, and
at 1, Figures 1 and. 2, which will be seen to present two openings for the
drivers to slide in, and a flange at front and back with a thinner flange in the
middle, to separate the two drivers, and prevent their rubbing together.
When in motion the two sliding surfaces present a horizontal part and a
bevelled part to each driver, and by notches of a corresponding form w, w,
being cut into the drivers at proper intervals on the top and bottom edges, the
necessary rising and falling motion is made to take place at the proper time.
These brasses are fixed by wood screws. There is also a set of brasses on the top
side of the drivers m, Figures 1 and 2, and one of which is shewn at Figure 4,
which differs from the one at Figure 3 only in the lower part of it, where a
slot is cast into it, and a chamber for the head of a screw pin to lie in, so as to
be flush or level with the surface of the brass. This pin passes through tho
bed of the batten, and is secured at the back with a thumb nut. The top
pair of drivers slide in brasses 5, Figures 1 and 2, of the same form in the
openings as those just described, the only difference being in those parts which
are required for fixing.

page_text: Figure 5 shews this brass extended at the sides to a sufficient length for it to
reach across one space, and be secured by wood screws to two of the poppets.
Figure 6, and 6, Figure 2, shews one of the top brasses, the fronts of which
are seen at 6, Figure 1, which is made of this form so as to reach across the top
of the poppet and down the back side, so as to be fixed there with. a thumb
screw and nut. All these brasses, Figures 3, 4, 5, and 6, have this property
peculiar to their form, viz., that the square side of the sliding surfaces acts as
a stop to their respective drivers, the upper brasses stopping the drivers when
up and in connection with the shuttle, and the lower brasses stopping the
drivers when down and not in connection.
The
pegs used for the bottom shuttles are of the common form, and need
not be described. Those used for the top shuttles are of the form shewn in
Figure 7, and 7, Figures 1 and 2, being turned like a hook, in order to act
underneath the shuttle. The front pegs of this set are slightly twisted, as
seen in Figure 2, so as to bring the end of the front peg into a line with the
inside peg, so that the holes in the shuttle may be in a line.
.
The slide used for giving motion to the drivers is of wrought iron, and is of
the form seen in a front view at n, Figure 1, and in an end view at n,
Figures 2 and 8, and moves on two rollers o, o, Figures 1 and 2, giving motion
to the bottom drivers by means of a projecting stud p, Figures 1 and 8, which
works into both the driver hooks. p, p, Figure 8, also shews the top and
bottom drivers, and the way in which the hooks are rivetted on. The top
drivers are furnished with a pair of hooks of the form shewn in Figure 9, and
9, Figure 1, which are placed at or very near the ends of the drivers; so as to
be actuated by the stud q, Figures 1 and 8, in the vertical limb of the slide n, the
action of which will be readily seen by any person conversant with power looms
for ribbons. In order to give steadiness to the vertical limb of the slide n,
it,is passed through a plate of iron r, Figures 1 and 2, (this plate is shewn in
Figure 2, cut through, to shew the pegs, but it would not be seen cut through
in this position,) which has a slot made in it long enough to allow of the
proper amount of motion required, and which plate is secured to the two
last poppets of the batten by pins passing through them, and nuts on the
back side. On the top side of this plate, and close behind the groove or slot
in which the slide works, is fixed one of the bottom brasses, marked 5, the
object of this brass being to secure a steadiness and certainty of motion in
the hooks on the ends of the drivers. The end of the batten at which the
slide is worked will require to be longer than the other end, in order to allow
the required amount of motion in the slide being obtained beyond the last
space in the batten, and this extra length will vary according to the width of

page_text: the spaces in the loom. It has also a portion cut away on its under. side,
shewn by the dotted line y, y, Figure 1, to allow of the rollers o, u, and
the straps 8, 8, being obtained in the best position.
The method of attaching this slide to the parts which give it motion is by
means of straps shewn by dotted line 8, 8, 8, rivetted to the small projecting
plate t, Figures 1, 2, and 8, which is screwed to the slide. One of these
straps passes round a roller at the back of and on the same pin as 'o', and
the other round a roller u, from which they both meet upon the pulley v,
which is similar to that used generally for this purpose. Along the top
of the batten, and over everything, I place, for the protection of all the parts,
and for convenience, a brass tube z, z, which is made moveable, so that it can be
taken off at any time. Figure 2° shews the method of attaching the batten to
the sword, and also to the connecting rod. c, c, is a casting similar to those in
common use for this purpose, and fastened to the batten by the screw pins e, e.
The sword a, a, is curved or bent backwards from its original position over the
middle of the batten, and brought down at the back as far as the collar b,
below which it is wrought into a flat plate d, and secured to the casting c, c,
by the screw pins f.f, instead of being passed through the block of the batten,
and fixed with a nut, as usual, which cannot be in this case, from the space
being otherwise occupied. ġ shews the hole into which the pin of the con-
necting rod is put in the usual manner. The improvement- in the breast
piece consists in a series of small castings a, a, Figures 10 and 11,
screwed on the rail of wood, having notches cast into them for the recep-
tion of a wire pin or axis c of the roller b, over which the work passes.
Figure 10 shews an end view and Figure 11 a front view of this arrange-
ment where the alternate levels of the rollers are seen. The axes of the
back rollers work in castings screwed to a rail of wood, as seen in Figure 12.
d, d, is the rail of wood; e, e, are the casting; f.f, the rollers; g, a
casting which shews the way it is attached to the loom. There is this
additional advantage over those in common use, that the rail is inverted,
and instead of being placed below the rollers it is placed above them,
whereby it is brought inside the silk, and more room is obtained for the hand
in the operations in the back shed or opening.
The motion which actuates the shuttles will be seen at Figures 13, 14, and
15. Figure 13 shows a top view, Figure 14 a side view, and Figure 15 an end
view. A is a lever moving on a pin D. B and C are also two levers, of the form
seen at C, C, C, Figure 14, moving on the same pin, and having projecting
arts, E, E, Figure 13, opposite to the large end of the lever A, which is cast
hollow, and contains within it a bolt F, Figures 14 and 15, with the ends bevilled,

page_text: as will be seen at Figure 15, where one end of this bolt is seen in contact with
the projecting part E, and the other end is shewn by the dotted line. There
is a small cavity made in one side of this bolt, as will be seen in the dotted
Figures in Figures 16 and 16b, and in 16b, this will be seen to contain a small
spring, the object of which is to keep the bolt steady in its place, and prevent
its moving except at the proper time. These two Figures shew the bolt its full
size. The curved parts of the levers B and C have a slot in them G, which
carries a projecting stud, as seen at H, H, Figure 15, (the nut which fastens
it is also seen at H, Figure 14,) which stud is bevelled to correspond with the
bolt F. I, I are two rods which connect the motion with the batten, and are
seen in continuation at I, I, Figure 1, where it will be seen that the rods are
passed through the ends of the straps (which are shewn black), and are
screwed, and furnished with nuts and washers, K, K, K, K, for adjusting the
tightness of the straps. The top roller L, Figure 1, with its strap, serves
only to keep the bottom straps tight, and to sustain the weight of the rods I, I.
The rod M, Figure 14, gives motion to these parts, and is connected with
parts to be described hereafter. The action of this motion is as follows:-
Suppose the levers A, B, C to be in the position seen in Figure 15, with the
bolt F in contact with the part E on the lever B, then upon the raising of the
rod M, Figure 14, the other end of the lever A will be depressed, until the
bevelled part of the bolt F comes in contact with the bevelled stud H on the
lever B, when the bolt will be driven from its place till it gets into the
position shewn by the dotted lines F, Figure 15. The rod M is in its turn
drawn downwards, which elevates the bolt F, which comes into contact with
the projecting part E on the lever C, when that lever is drawn upwards,
while the lever B is drawn downwards. The rod M is again elevated, and now
the bolt F comes in contact with the bevelled stud H on the lever C, when it
is driven across to its former position, and upon the rod M being depressed
it comes in contact with the projecting part E on the lever B, and the levers
are again drawn to the position scen in the Drawing.
Figure 17 shews the means by which motion is given to the rod M.
N, N, is a portion of the loom frame. O is the crank shaft; P the pedestal
in which it works. Q is a crank fitted on to the end of the shaft. R is a
roller working on a pin fixed in the slot of the crank. S, S; is a lever moving
on a pin U fixed in the casting V, having a large opening in it for the roller
R to move in, and smaller slots above to carry the pin T, on which the bottom
end of the rod M works. By the revolution of the shaft O and crank Q, a
peculiar motion is transmitted to the rod M, being sharp and rapid in its
upward stroke, and very smooth and gradual in its downward stroke, when it

page_text: is actuating the shuttles, so that they are drawn across in a very gentle and
easy manner. The direction in which the shaft revolves is seen by the arrow.
Figure 18 shows this motion, as seen from the back of the loom, and the
parts seen are lettered to correspond with Figure 17. The leishes or harness
is mounted up with the spaces at alternate levels to correspond with the levels
of the shuttles in the batten. I would remark in respect to this part of my
Invention, that I am aware that it has before been proposed to place the
shuttles of looms in two planes, one above the other, in which case the shuttles
were driven by means of racks; I do not therefore claim such arrangement of
the shuttles generally.
The second part of my Invention consists of a new and improved
method of constructing and arranging the battens for looms to carry two or
more shuttles to each ribbon or fabric, so as to make double shots, plaids, or
tartans, or any kind of ribbon or fabric requiring more than one colour to be
introduced in the shute, and also in a new and simple motion for actuating the
shuttles in such battens, which motion is far less complex and more certain in
its operation than those now in use for this purpose.
The construction of this batten will be seen by a reference to Figures 19,
20, and 21. A, A, A, in these Figures is the bed or block of the batten,
and in Figure 19 its outline is shewn by double lines, in Figures 20 and 21 by
a thick black line. B, B, B, are a series of upright pieces of hard wood,
which are morticed into the back side of the bed or block, as will be seen in
Figure 19, where a is a tenant let into the block, and the dotted line b, b,
shows the distance to which they are let into the back side of the block.
c, c, are two wood screws which secure each piece in its place. C, Figure 19,
also seen shaded in Figure 20 and 21, are brackets of iron or brass, fixed to
the upright pieces, and secured by pins and nuts d, d, Figures 19 and 21.
These brackets carry the planks or slides D, D, for the shuttles to move in. The
front and middle planks are fixed by screw pins and nuts e, e, Figure 19, and
the back plank is held by wood screws, as at f, Figure 19. The shuttles E, E,
which move in these planks, are of a new form, and will be seen at Figure 22,
which is a view of the under side, and Figure 23, which is a front view. g, g,
in these Figures, is a tongue or projecting part on each side of the shuttle,
and corresponds to the parts marked g, in Figure 19. The planks have cor-
responding grooves in them, which these tongues slide in, which is seen in
Figure 19. The eye through which the shute passes from the quill is of steel
wire, and is placed at the bottom of the shuttle, so that the shute comes under-
neath the shuttle to the ribbon, instead of through the front part, as is the case
in other shuttles. This eye is seen by the black line h, Figure 22, and the

page_text: black dotted line h, Figure 23. i, i, are the holes in which the driving pegs
act. It will be seen by Figures 19 and 21' that the shuttles are arranged in
rows behind one another, instead of above each other, as is the case in the
looms at present in use with more than one shuttle to each ribbon, and this
difference in the arrangement enables me to dispense with all the parts and
apparatus for raising the shuttles to the various levels required at different
times, because all the shuttles in my arrangement are constantly at the proper
level for passing through the shed or opening when required.
The pegs which I use for drawing the shuttles across are like those in
common use, except that I use them an inch and three quarters long. above
the driver, instead of an inch and a half which is the usual length; and I
make this difference in order to be able to increase the depth of the shed or
opening a little, so as to give the front shuttle sufficient room to pass through.
These pegs are marked N on Figures 19 and 20. The drivers F, F,
in these Figures move between top and bottom brasses, with surfaces for
them to slide upon, the same in form and arrangement as those shewn in
Figures 8, 4, 5, and 6, but they are made so as to embrace two or more pairs of
drivers, as may be required. The parts colored blue in Figures 19, 20, and 21
show theso brasses. It will be seen that the bottom ones are fixed with wood
screws, j,j, Figure 19, to the bed of the batten, and the top set are fixed on the
top of a small piece of wood shewn by dotted lines at G, Figure 20, morticed
into the bed between the drivers, and secured by a taper screw k, which is
screwed through the piece of wood and into the bed, and has on the top 'a nut,
which secures the brass, and is sunk into a cavity on the top of it. This cavity,
with the nut, is shewn by the dotted lines at 1, Figure 19. The hooks which
move the drivers are of the form seen at H, H, Figure 20 (also seen in section
at H, H, Figure 19), and are sufficiently long to come below the bottom
of the bed, so as to be actuated by the stud I, upon the slide K, which runs
upon the rollers L, L (seen in Figure 19, and also by the dotted circle L, L,
Figure 20, where the plates to which they are secured are seen), and is drawn
by straps shewn by the dark lines m, m, Figure 20, which pass to the roller or
pulley M, Figures 19 and 20, which is similar to those in ordinary use for this
purpose, and is carried by a plate t, Figure 19. The slide, drivers, hooks
and pegs, of the back set or sets of shuttles, are like those used for the
front set just described, and are shewn red in Figures 19, 20; and 21. S
The hooks of these drivers pass down through a mortice seen at n, Figure 19,
cut in the bed of the batten, of sufficient length to allow of the required
amount of motion, and so come into contact with the stud and slide which
actuate them. The stud which gives motion to the back set of shuttles in the

page_text: Drawing is seen at o, and the slide at p, Figures 19 and 20. The mode
of fixing the slays in the batten is seen in Figures 19 and 20, where q
is an iron casting, extending across between two of the upright pieces B,
to receive the bottom end of the slay. r is.a brass or iron slay holder of a form
well known, also fixed to the upright pieces B. s is the slay, which is seen
without obstruction in Figure 20 by the partial removal of the planks and
shuttles. The cranks which I use for giving motion to this batten are longer
in the throw than those in common use for looms with only one set of shuttles,
in order to draw the slay sufficiently far back to give room for all the sets to
pass through the shed or opening in front of it. Thus, the throw for an ordinary
loom being five inches and three-quarters for one with two sets of shuttles,
on my plan it will require the throw to be seven inches; for a loom with three
sets of shuttles it will require the throw to be eight inches and a half; and so
on in proportion. The slays are also a quarter.of.an inch longer in the dents
than those in common use, to give room for a little deeper opening. The mode
of connecting the batten with the sword and connecting rod is the same as
that seen at Figure 2, a, and hercin-before described. The parts and arrange-
ments which give motion to the slides, drivers, and shuttles will be seen
by reference to Figures 24, 26, and 27. Figure 24 is a view, as seen
from the end of the loom. Figure 26, as seen from the back of the loom, and
shews two distinct motions, as there are two sets of shuttles in the batten here
described, and in any case each set of shuttles will require one of the arms I,
and an under motion, to itself. Figure 27 is a top view of the parts situated
under the loom A. Figures 24 and 26 are parts of the loom frame. B is the
floor line. C is the crank shaft. D is.a portion of the rim of the fly wheel.
E is a crank fixed on the end of the shaft, and carrying a small roller F,
which works in the slot of the arm or lever G, and gives motion to the shuttle
shaft H and the arms or levers I, which have fixed to them the pins or
bars J, J. These pins or bars have a collar a near the middle, which is
brought up against one side of the arm I, the pin J being passed through the
slot c. A nut 6 is screwed up against the other side of the arm I, which makes
the pin J fast. Underneath the loom is a framework of wood or iron, con-
sisting of a flat piece d, which is screwed to the floor, and three upright
pieces, K, L, M, Figures 26 and 27, one of which, K, is seen in Figure 24.
Through these upright pieces a pin e is passed, which has on it two rollers f,f,
Figures 26 and 27, which are shewn in section by the dotted circlef, Figure 24.
Towards the back side of the loom, and also fixed to the floor, is a plate g;
Figures 24 and 26, in which is rivetted a pin h, upon which works a roller i,
and above which is fixed by a nut a plate m, of the form seen shaded in tho

page_text: Drawings, the lowest part of which supports the lower ends of the slides,
which are two straight pieces of wood, and are shewn red, and marked k
and . This plate will be plainly seen in Figure 25, which is an enlarged
and detached view of these parts. The slides are connected together by an
elastic strap (I use vulcanized india rubber) n, seen black in Figure 27,
which passes partly round the roller i, and is fixed to each slide by a wood
screw. To the other end of these slides are screwed straps w, w, Figures 24
and 26, which pass partly round the rollers f. f, and being continued
upwards are attached by a swivel nut, with right and left-handed screws, to
the straps marked w, w, Figures 19 and 20, thus connecting the slides with
the parts which move the shuttles, so that whatever motion is imparted to
the slides will be communicated to the shuttles. The ends of the slides at
which the straps w, w, are attached are supported by a pin o, Figures 24
and 26. In the middle part of the slides is cut a slot or mortice, seen at p, p,
Figure 27, in each of which is placed a hook or catch of the form seen at r, r,
Figure 28, which hooks are held in the mortices by a pin s, which passes
through them and the slide, and on which the hook moves freely. The pin,
Figure 28, is also passed through the slide, and serves to support the hook, and
prevent its falling out of the mortice. The pin y in the lower part of the
hook prevents its rising up too far in the mortice. Underneath the slides,
and passed through the upright pieces K, M, is a rod or bar of iron N
(which I call the lifter), Figures 24, 26, 27, which at one end has a
lever P attached to it, and immediately underneath the slides it has also
two plates of iron rivetted through it. These plates are curved gently
downwards, as will be seen at Q, Figure 24. Figure 29 shews this lifter
detached, and the parts are lettered the same as in the Drawings to the lever P.
In each motion is attached a cord a, which passes up to the Jacquard machine,
and is attached to a hook in it, which hook is set apart specially for the purpose
of raising the cord a when required, which raising is regulated by holes stamped
in the cards of the machine, as the pattern may require one or other of the
sets of shuttles to be brought into operation. The action of this motion is
as follows:-Suppose the parts to be in the position seen in Figures 24 and 27,
with the projecting part of the hook r, Figures 24 and 28, just in contact
with the curved plate Q, Figure 24, then, upon motion being given to the
loon in the direction shewn by the arrow, Figure 24, the cord x is raised,
and with it the plates Q and hook r, to the position in which they are shewn
by the blue lines. The motion continuing, the stud or pin J of the arm I passes
into the hook, and carries it and the slide k backwards with it till it arrives
at the position in which the arm I and lever G are shewn by the blue lines

page_text: during which time the other slide, Figure 27, is drawn forward by its
strap w to the position which the slide ke had just left. The motion still con-
tinuing, the arm I begins to come forward (leaving the hook r to fall down into
its mortice, where it rests on the pin z, Figure 28), and does so till it is again
in the position seen in the Drawing, Figure 24; and the Jacquard machine
having fallen, the cord a, lever P, and plates Q, are also by this time in the
position they were at first. The cord x is again raised, and with it the lever P
and plates Q; but this time it is the hook in the slide k² which is raised with
them, and this is caught by the pin J, and with its slide carried backwards to
the end of its stroke, while the slide k is drawn forward to its original position.
The arm I continues to describe a smooth and easy motion between the
two positions shewn in Figure 24, and as the hooks and slides cannot be acted
upon without the previous raising of the cords a, it is evident that whichever of
the cords is raised the set of shuttles belonging to it, and that set only, will
be acted upon while the same cord continues to rise, and that instantly upon
the raising of the other cord the other set of shuttles will be brought into play,
while the set at first in use remain at rest until called into use again by the
raising of the cord belonging to them. One shoot or any number of shoots of
cach shuttle, whether the looms has two, three, or more sets of shuttles, can thus
be thrown at pleasure, as the pattern may require, without the least difficulty.
Having thus described the nature of my Invention, and the manner in
which the same is performed, I would remark that I do not confine myself
to the details herein described, so long as the peculiar character of either part
my
Invention be retained. But what I claim is,-
of
First, the application of drivers moving above the shuttles, and actuating
them by.pegs turned up from underneath; also the form of the hook which
is attached to these drivers; also the form of the brasses within which the
drivers move; also the construction of the middle plank; also the form of
the slide, the mode of carrying the same, and the actuating two pairs of
drivers by means of one slide; also the parts by means of which the motion
is communicated from the shaft of the loom to the slide pulley; also the
mode of attaching the batten to the sword and connecting rod, and also the
castings on the breast piece and back rail, in order to obtain two rows of
rollers at the required levels. And,
Secondly, I claim the means of arranging two or more sets or rows of
shuttles (dispensing with the parts heretofore required for lifting and falling
the shuttles); also the arrangement of shuttle, and the mode of sustaining
it between two grooved planks, by means of a tongue or rib on each sido
of the shuttle; also the sustaining and fixing the planks by means of a

page_text: horizontal bracket placed above them, instead of vertical supports from below;
also the arrangement of parts (for giving motion to the shuttles) which inter-
vene between the slide pulley and the crank shaft, by which means I am
enabled to drive two, three, or more sets of shuttles without the use of spur
wheels, tappets, or treadles, without requiring the batten to be longer than
usual at either end.
In witness whereof, I, the said Thomas Robinson, have hereunto set my
hand and seal, this Fifteenth day of July, in the year of our Lord
One thousand eight hundred and forty-eight.
