page_text: LETTERS PATENT to John Carter Ramsden, of Bradford, in the
County of York, Stuff Manufacturer, for the Invention of "IM-
PROVEMENTS IN APPARATUS, OR THE MECHANISM OF LOOMS FOR WEAVING
A CERTAIN CLASS OF PLAIDS. CHECKS AND FANCY WOVEN FABRICS."
PROVISIONAL SPECIFICATION left by the said John Carter
Ramsden at the Office of the Commissioners of Patents, with his
Petition, on the 28th November 1853.
I, JOHN CARTER RAMSDEN, of Bradford, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN APPARATUS, OR THE
MECHANISM OF LOOMS FOR WEAVING A CERTAIN CLASS OF PLAIDS, CHECKS,
AND FANCY WOVEN FABRICS," to be as follows:-
These improvements relate, first, to mechanism to be used in weaving
those fabrics in which several shuttles are employed, and in which cir-
cular shuttle boxes are used fixed on the end of the "lathe," and consist
in the manner of actuating the shuttle boxes to produce the required
changes of weft. This is effected by mechanism, fixed on the framing
of the loom which comes into operation (causing the shuttle to revolve

page_text: one way or the other as required) when actuated thro' connecting
rods and levers by a wheel or mechanism similar to that described
in the Specification of a Patent granted to me for "Improvements in
Looms for Weaving," dated the 30th of March, 1853, No. 765, for
effecting changes in the working of the healds therein referred to, which
wheel or apparatus, by inserting pins according as the changes are
required in the weft; may be employed to effect the changes both in the
working of the healds and shuttles in fabrics where such is required.
These improvements relate, secondly, to another arrangement of
mechanism, which may be used for the purpose for which the wheel
before referred to is employed, namely, for effecting changes both in
the shuttle box and healds, which consists in a wheel having grooves
formed in it, into which the end of a lever takes, that communicates
with tappets or other parts to be brought in and out of operation. This
lever is connected with a spring or other mechanism, which will pull-at
the lever at certain times, so that, when a "
gap
or cut in a space
between the grooves by the slow revolving of the wheel (which will be
at the points where the, changes are required) comes opposite to the
end of the lever it will pass from one groove to the other, where it will
remain till another cut or gap permits the spring to pull it back to the
other groove, and thus-effect-the-changes-required. The spring for
pulling the lever may be worked by "cams or excentrics, or from the
lathe, or by other mechanism.

to on the framing of the loom for effecting the changes of the weft may
be catches, pawls, studs, or toothed racks, or other mechanism attached,
so as to be risen or lower by the mechanism referred to being arranged
so that ratchet or other wheels on the axis of the shuttle box will play
between or clear of them when changes are not required, but when
required the position of the catches, pawls, studs, or toothed racks are
changed, so that by the vibration of the lathe they will come in
contact and operate upon the ratchet or other wheels on the axis of.
the shuttle box, which is turned one way or the other according as it
is the upper or lower sides of the ratchet wheel or wheels which is
operated upon. These improvements relate, secondly, to another
arrangement of mechanism, which may be used for the purpose for
which the wheel before referred to is employed, namely, for effecting
changes both in the shuttle box and healds, which consists in a
wheel having grooves formed in it, into which the end of a lever
takes, that communicates with tappets or other parts to be brought in
and out of operation. This lever is connected with a spring or other
mechanism, which will pull at the lever at certain times, so that when
a "gap" or cut in a space between the grooves by the slow revolving
of the wheel (which will be at the points where the changes are
required) comes opposite to the end of the lever, it will pass from
one groove to the other, where it will remain till another cut or gap
permits the spring to pull it back to the other groove, and thus effect
the changes required. The spring for pulling the lever may be worked
by "cams or excentrics, or from the lathe, or by other mechanism.

filed by the said John Carter Ramsden in the Great Seal Patent
Office on the 26th May 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
JOHN CARTER RAMSDEN, of Bradford, in the County of York, Stuff
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of November, in
the year of our Lord One thousand eight hundred and fifty-three, in the
seventeenth year of Her reign, did, for Herself, Her heirs and succes-
sors, give and grant unto me, the said John Carter Ramsden, Her
especial licence that I, the said John Carter Ramsden, my executors,
administrators, and assigns, or such others as I, the said John Carter
Ramsden, 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
make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Inven-
tion for "IMPROVEMENTS IN APPARATUS, OR THE MECHANISM OF LOOMS FOR
WEAVING A CERTAIN CLASS OF PLAIDS, CHECKS, AND FANCY WOVEN
FABRICS," upon the condition (amongst others) that I, the said John
Carter Ramsden, by an instrument in writing under my hand and
seal, should particularly described 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 John Carter Ramsden, do
hereby declare the nature of my said Invention, and in what manner
the same is to be performed, to be particularly described and ascer
tained in and by the following statement and accompanying Drawing
(that is to say):
These improvements relate to mechanism or looms to be used in the
weaving of those fabrics in which several shuttles are required, and in

page_text: which circular or rotatory shuttle boxes are employed, and it consists
in the construction, arrangement, and combination of mechanism for,
and mode of actuating the shuttle boxes, to produce the changes of
weft required by the pattern to be woven. It also consists in the mode
and arrangement by which changes of the weft are combined with
changes in the working of the healds, or in a mode in which the present
improvements for effecting changes of weft in weaving may be com-
bined with the improvements in looms for weaving, for which a Patent
was granted to me, numbered 765, and dated the Thirtieth of March,
One thousand eight hundred and fifty-three. In the following expla-
nation of my Invention I shall have to refer to the several Figures of
the Drawing annexed hereto, in which the mechanism relating to my
Invention is delineated, together with such parts of the ordinary and
well-known parts of looms as are necessary for the explanation thereof;
the ordinary parts of the loom not shewn being omitted, that the parts
relating to my Invention may be more clearly comprehended, and which
being well known can be readily added. Fig. 1, is a front elevation;
Fig. 2, an end elevation; Fig. 3, is a plan view, the parts above the
shaft C being supposed removed; & Fig. 4, a sectional elevation from
the end shewn by Fig. 2, that end being supposed removed up to the
first cross stay A¹. The same letters and figures of reference will be
used to denote similar or corresponding parts on each Figure of the
Drawing. Before proceeding to describe the peculiarities of my In-
vention, I will name those ordinary parts of the loom shewn in the
Drawing. A, is the framing of the loom; A', are the cross stays; B,
crank shaft; B', pinion on end of crank shaft, driving wheel C¹ on
plain tappet, and picking shaft C; C, pinion to give motion to wheel
driving the tweeling tappets (not shewn); D, the fluted roller for taking
up the fabric as woven; D', a series of wheels giving motion to the
roller; D, E, roller on which the cloth is wound; F, the slay; F', slay
swords; F, fulcrum of the slay. In the first place I will describe the
construction of the shuttle boxes: the one on the right, at the front of
the loom, is the ordinary shuttle box, with the picker arranged in the
usual manner; that on the left is the circular or rotating shuttle box.
The one shewn in the Drawing (a,) has boxes or spaces for six shuttles.

page_text: For the purpose of description it may be considered a cylinder of the
length of the shuttles with flat ends, having round it 6 grooves cut
longitudinally for the shuttles, the grooves being provided at the outside
with flanges or lips on each side to retain the shuttle from falling out,
yet leaving a narrow groove a', sufficient for the picker b, to pass
through. It is made..of wood, the flat ends being faced with brass
plates a², which have central bosses, through which the axle shaft or
stud a³ passes; f³ is a frame secured to the end of the lathe; and fis
an arm from the fulcrum of the slay, for the purpose of giving steadiness
to the frame f³, through the connecting stay f, which is secured into
the arm, but is free to turn in the bracket f, secured to the frame.
The stud or axle shaft a³, on which the shuttle boxes rotate, is secured
by one of its ends at a', in the frame f", and the other end of the shuttle
boxes are steadied as they turn by the rim a³, of the end brass plate,
taking into grooves in a forked piece a secured to frame f³; (as shewn
in the Drawing, the forked piece a' has no provision made by which
to adjust it by, but it is advisable that it should have an adjusting screw
and lock nuts, so that the shuttle boxes can be nicely set); by this
arrangement (as a space is left between the ends of the shuttle boxes
and the batten, say two inches,) the threads from the several shuttles
do not get wound round or entangled with the axis of the shuttle
boxes, which does not project beyond the face of the boxes. I need
scarcely say that the shuttle boxes are adjusted so that the upper
box is on a level or corresponds with the shuttle race. One end of
the picker spindle is fixed in a bracket f, secured to the slay
sword, the other end in the frame f³, to which is also secured a
forked guide piece f8, within which the picker 6 passes after each
pick. The shuttles are prevented from getting out of the ends of the
boxes, or out of their proper places, by two plates a³ and a³, secured
to the frame f³ at each end of the boxes, leaving a small space for
clearance. The plate as, at the back end of the shuttle boxes (supposed
removed in Figure 2) covers the holes of all the boxes, except the upper-
most or the one opposite the shuttle race; the plate aº, at the inner end
of the shuttle boxes, does the same, except that it leaves a portion of
those sides of the holes nearest the centre uncovered, so that the weft

page_text: threads may pass through; two ratchet wheels having six teeth a' and as
(which will be herein-after further referred to), and one six sided dise
a, placed side by side, are secured to the shuttle boxes a; the sides of
this disc piece a corrrespond with, each shuttle box. It is by this the
shuttle box containing the shuttle to be used is retained opposite the
shuttle race, as its sides are pressed against by a T formed c, which is
held perpendicular, but is free to slide up and down by the frame f³
and bracket c', secured to it through holes in which the T. piece
passes, being forced up against the sides of the disc by an elastic
spring C², formed by a series of tempered plates which are screwed to
the frame f. The sides of the disc piece are hollowed so that the
T piece will be sure to bear firmly against both corners of the side, and
thus secure the true position of the box, even if the corners should
wear. As I do not use swells in my shuttle boxes, I employ that
arrangement of reed known as the "loose reed," which will give way
when, the shuttle is caught in the shed. The shuttle boxes can be
rotated in either direction, and when a change in the weft is required,
it takes place after the shuttle is returned to the circular shuttle boxes,
and during the time that the lathe is beating up the weft. An arm a¹,
from the end frame of the loom is brought out, and to the end of it on
studs (d, d',) are fixed catches or pawls d², d, which are each placed
opposite one of the two six toothed ratchet wheels a, a, secured to the
shuttles boxes a, one pawl d taking on the upper, and the other don
the lower side of each ratchet wheel (which have their teeth in contrary
directions); these pawls each rest against pins d', d, fixed in the arm
of the framing A2, one being kept against its pin, when not otherwise
acted upon by a spring d (of india-rubber), and the other by its own
and the gravity of the parts in connection with it; when in this position
the ratchet wheels, on the beating up of the slay, will just pass clear
between them. When a change of shuttle is required the upper pawl &²
is lowered, or the lower pawl d³ is risen, according as the pattern may
require next, that shuttle on the front side of the one in use before the
change, or the one on the back side, so that when the lathe beats up, a
tooth of one of the ratchet wheels will come in contact with the end of
its pawl, which will push the boxes one tooth as the lathe advances, to

page_text: beat up.
I have now explained and described the arrangement and
construction of the shuttle boxes, and the mode in which the rotatory
shuttle boxes are made to change; it will be obvious that the changes
may be effected by acting on the pawls d, d, by hand as well as by the
mechanism which I am now about to describe, keeping in view in the
first place mechanism for effecting changes (as the pattern of the fabric
may require) in the shuttle boxes solely; but before doing so, it will be
best to explain here (though it may be well known) that the weaver
should arrange the shuttles for the different wefts intended to be used
in the fabric, in such manner, that each shuttle (and thus each weft)
may be woven in the order or succession required by the design or
pattern of the fabric, by moving the rotatory shuttles boxes one box,
either backward or forward, though in some patterns it may be neces-
sary to use more than one shuttle of the same weft to weave one part
of the pattern, so that on completing that part the next weft required
may be brought up by a movement of one box. It will therefore be seen
that the mechanism, as shewn arranged in the Drawing, is not intended
to turn the shuttle boxes more than one box for one movement; in this
case, it therefore only remains for the mechanism to select which of the
two pawls shall act, and when it shall act; but should the shuttles be
arranged that a movement of more than one box is necessary to bring
the required shuttle up, then this may be done by extra pawls, each
longer by the space of a tooth of the ratchet than the other, so that on
the beat up of the lathe the ratchet wheel will strike the longest first,
and the others in succession, each pushing the ratchet wheel a tooth,
and thus a box; in this case the mechanism will have to select which
and the number of the two series of pawls shall act, and when they
shall act. The mechanism which I employ to do this is a wheel e
(which I make as large in diameter as I can conveniently), having
holes e, formed all around near the edge, the space between the holes
being what the wheel is made to move during two picks; at the pick or
time when a change is required a pin is placed in the hole in the wheel,
which will at that time be opposite thé miechanism on which it will have
to act upon, and it is placed so as to project on one or the other side of
the wheel, according as it is the upper or lower pawl which is to be

page_text: acted upon, as the case may be; and if a series of pawls are employed,
then the pins must be made of such lengths as are necessary to actuate
the number of pawls required; if one pawl is only wanted, it must
reach to the mechanism connected with the pawl which acts last; if two,
to the last but one, and so on; the pawls and mechanism for actuating
them being placed side by side. It will be seen by the Drawing that
the wheel here referred to is fixed on a stud e', secured to the side of
the loom; it receives its revolving motion from a shaft g, through a
series of toothed wheels g', 9, 9, 9'; this shaft g derives its motion
from the shaft c, by means of an excentric h, secured on the shaft c,
which takes between the prongs of the forked arm of the lever h',
which has its fulcrum on the framing at h³, giving to it a vibratory
movement, and to the pawl h³ jointed with it, which takes on to a
ratchet wheel g, secured on the shaft g; h' is a pawl placed on a stud
fixed in a piece secured to the framing to prevent backward motion.
The pins in the wheel e act on levers i, which may both be placed on
one stud secured in the framing, when the pawles d, d³, are actuated
from one source only, but otherwise they may be placed on two
shafts, ; the shafts act through arms 2,, and connecting rods ",",
on the pawls d, d. The ends of the levers i are inclined, so that when
the wheel e moves forward and brings a pin in contact with one of
them it will be forced back, and thus actuate the pawls d³ or d³, in con-
nection with it. From what has been described it will be seen that the
pattern wheel e receives its motion intermittently, its motion terminating
about when the lathe begins to move towards the beat up, leaving the
pin which may happen to come against one of the levers. i, at that point
at which it will have forced the lever furthest back, there to wait till
the change is effected. To prevent the wheel from advancing too far
by the impulses giving it motion, a cord k is passed from a spring kl
round it, in a groove cut in its edge and over a flat spring, and then
secured to a stud on the framing. The wheel e, shewn in the Drawing,
is supposed to be divided into two hundred and forty parts, and each
change requires (to work with certainty) a motion through a space
equal in length to about the distance between the holes in the wheel, so
that the wheel is equal to a pattern which is repeated in two hundred

page_text: and forty picks, of not less than two picks to a change; but if a
change consisted of more than two picks, the quantity being a
multiple of two, then the wheel would be extended by the multiplyer;
that is, if not less than four or a. multiple of four picks were
woven to one change, the wheel would be equal to a pattern of 480
picks, but it must only be moved once in four picks, and the move
ment should only occupy the time of an half revolution of the crank
shaft B. But besides the method just explained, there is another
by which larger patterns may be woven, than can be woven by the
wheel e alone, should the pattern required have extensive portions of
some of its wefts. I select so much and as many of the largest as will
make the number of picks in the repeat of the pattern, when added to
the number of picks the wheel can give, and I then arrange the
pattern wheel so that it will not move during the times those. portions
are being woven, except one movement when each change is required;
by which arrangement I economise its circumference for the smaller
parts and more frequent changes. I accomplish the stopping and
starting of the pattern wheel, at the proper intervals, by mechanism
acting in like manner to the pattern wheel described in the Specification
of a former Patent herein-before referred to, as dated the Thirtieth
March, One thousand eight hundred and fifty-three, and numbered 765.
This wheel (1) makes one revolution during one repeat of the pattern;
it is advanced by an excentric m, on the shaft c, and by a lever m',
pawl m², taking into a ratched wheel m³, all similar to h, h', h³, and g',
respectively, herein-before referred to, the motion from the ratchet
being transmitted through toothed wheels to one l', on the same stud
(12) on which the pattern wheel is placed, the two wheels & and l, are
not fast together, but the toothed wheel has a pin in its boss that
takes in a space in the pattern wheel 1, the piu in the wheel l' pushes
forward the pattern wheel 1, when it comes against the side of the
space; but the pattern wheel I can be pulled forward in the same
direction as the other pushes, without obstruction from the other
wheel. The pattern wheel is fed or pushes forward slowly, too
slow in itself to effect any required change quick enough, as explained
in the Specification. already referred to, and the same means are

page_text: employed as therein described to effect a quick advance of the pattern
wheel for a small space; pins being placed on the periphery of the
wheel at the points where the changes are required, by which the wheel
is suddenly advanced; when one of them is brought within the range
of the prawl 1, which is attached to and vibrates with the slay sword.
The pattern wheel does not move after the sudden advance till the
pin in the wheel overtakes. it, and that it may not move by the
friction of the pawl, a spring 1, secured to the frame, is made to bear
against it. The pattern wheel lis. made in this case like a pully,
portions of its edge are cut away to produce the actions, as required, on
the friction bowl n, held in the forked end of the rod n', which joints
with the end of the forked lever n², having its fulcrum on the framing
at 3; this forked lever takes into a groove in the boss of the excentric
h, (which is loose on a fixed key) that gives motion to the pattern
wheel e, the action of the pattern wheel 2, being to slide the excentric
or the shaft c, out of the forked arm of the lever h', while the lever
is brought back to bring the excentric in the forked lever and the
friction bowl against the pattern wheel l, by a spring n', secured on
the framing, by which means the pattern wheel e is stopped and
started. Should those portions of the pattern selected to be woven
when the pattern wheel e is stopped, be a mixture of weft (or should
a fabric be required solely of that class), say alternately two picks with
one shuttle, and two with another, I then arrange a wheel p on the boss
of the excentric h, so that it will geer or be brought into geer with a
wheel P', of twice the number of teeth, fixed on a stud in the framing,
by the same movement which stops the pattern wheel e, the wheel P'
having a pin in it, which will alternately push outward the levers i, it,
on the same shafts (i) on which the levers are placed that are acted
upon by the pattern wheel e; these shafts i', are supported on a bearing
, secured to the framing, and on the end frame. That the wheels p
and p' may geer together at the same tooth, I attach a piece of wire p²
to the pin in p', and to a spring p', which will give way to the motion
of the pin, so that the elasticity of the spring p³, when the wheels are
out of geer, will always hold the wheel in the same position, the gravity
of the pin in the wheel causing it to seek the lowest point. So far I

page_text: have only spoken of mechanism for weaving fabrics having different
wefts, with a continuous interweaving of the weft and warp threads in
the same order, that is in which the healds are continually worked by
the same set of cams or tappets, but changes in the working of the
healds (made in the manner described in my former Patent already
several times hercin-before referred to) to combine with changes of
shuttles, may be made. The loom, as shown in the Drawing, is arranged
to weave a plain and tweel; the healds and tweel tappets for working
them are not shewn, but they are placed on a shaft which is carried in
a frame at the opposite end of the loom to that on which the wheel e is
placed; the shaft being revolved by the pinion c. The treadles for the
tweeling tappets are always in contact with their tappets, the cams for
plain being moved in and out of contact with their treadles only, and
thus a plain or tweel working of the healds is obtained as required. It
is explained in the Specification of my former Patent, that the plain
cams may be worked without disengaging the tweeling tappets, as the
treadle or treadles lifted by the tweeling tappets is arranged to belong
to those which are lifted at the same time by the cams for plain weaving.
The plain cams r, are slided in and out of gear by the lever r', which is
connected with another lever 2, by a connecting rod r'; the last named
lever is connected with another lever r', having its fulcrum secured on
the framing, this lever carries a friction bowl; strong pins e, are placed
in the wheel e, say at and over that space where tweel is required (in
the manner explained in the Specification of my former Patent), and
these pins will force against the bowl in the lever 1, and thus bring the
plain cams out of contact with their treadles, and keep them so as
long as the pins are continued, and when they have ended, a spring
will force back the lever r¹, and thus bring the plain cams into operation.
Some of the motions herein described may be obtained by other more
positive mechanical equivalents, but the mechanism which has been
described, to the best of my knowledge, is the most practical and useful,
as by its arrangement any of the ordinary misweavings of the pattern
to which such class of weaving is liable, can be with ease corrected;
the weaver having a ready command of the pawls m², h³, (strings being
tied to them which are brought to studs fixed close to the weaver's

page_text: hand on the frame at the front of the loom) by lifting which the pattern
wheels may be stopped until the picks required to make up for a mis-
weaving are put in, when by letting the pawls at liberty the weaving of
the pattern will proceed correctly.
I have now particularly described the nature of my Invention, and
the best mode I am at present acquainted for carrying it into effect,
and wish it to be understood that I do not claim all the parts shewn
in the Drawing, and herein described, as of my Invention; but claim
as my Invention, together with all modifications thereof, so long as
its peculiar characteristics are retained,―
Firstly, the arrangement of the parts and mode of constructing
rotatory shuttle-boxes as herein-before described.
Secondly, I claim as my Invention the application of a pattern wheel
like the wheel e, to select the times, the direction, and the extent
of change that the rotatory shuttle box is required to make, to
produce the pattern of the fabric required. I also claim the mode
in which the pattern wheel e may be used for the production of larger
patterns than it will by itself produce, that is, by an arrangement as
described of the pattern wheel 7.
Thirdly, I claim the mode shewn in the Drawing hereunto annexed,
and herein-before described, for producing alternate changes between
two shuttles, in like manner as described of the wheels P, P'.
Fourthly, I claim the mode of combining changes in the shuttle
boxes with changes in the workings of the healds as herein described.
Fifthly and lastly, I claim the general arrangement and combina-
tion of the mechanism and apparatus shewn in the Drawing hereunto
annexed, and herein-before described, for effecting the combined
changes and operations herein-before referred to.
In witness whereof, I, the said John Carter Ramsden, have here-
unto set my hand and seal, this Twenty-third day of May, in
the year of our Lord One thousand eight hundred and fifty-four.
JOHN CARTER RAMSDEN. (L.S.)

page_text: granted his fiat giving leave for the Amended Disclaimer and Memorandum
of Alteration hereunto annexed to be filed.
[The words in italic are underlined in original.]
In the Matter of a Patent granted to JOHN CARTER RAMSDEN, of
Bradford, in the County of York, Stuff Manufacturer, for the
Invention of "IMPROVEMENTS IN APPARATUS OR THE MECHANISM OF
LOOMS FOR WEAVING A CERTAIN CLASS OF PLAIDS, CHECKS, AND FANCY
WOVEN FABRICS," bearing date the Twenty-eighth day of November,
One thousand eight hundred and fifty-three.
ISCLAIMER AND MEMORANDUM OF ALTERATION proposed to be
entered by the said John Carter Ramsden, as such Patentee as aforesaid,
pursuant to the Statutes in that case made and provided.
WHEREAS in my Specification there are five separate claims to invention,
ut the one for the general arrangement and combination of the mechanism
nd apparatus for effecting the changes and operation of the rotating shuttle
ox is the only one which has become highly valuable, for which reason I wish

page_text: to disclaim, and I do hereby disclaim, all exclusive right to the use of the
separate mechanical parts of the machinery shown and described in the said
Specification, and I also wish to disclaim, and I do hereby disclaim, the several
parts of the Specification which describe and claim the parts of the Invention
mentioned in the first, second, third, and fourth claiming clauses at the end of
the Specification, and for this purpose I alter my said Specification by striking
out the word "all," and by introducing the words any of, and also the word
separately into the paragraph just before the claiming clauses, so that when
altered, it will be as follows:-"I do not claim any of the parts separately
"shown in the Drawing and herein described as of my Invention;" I also
strike out the words following, viz., "It also consists in the mode and arrange-
"ment by which changes of the weft are combined with changes in the
working of the healds, or in a mode in which the present improvements for
effecting changes of weft in weaving may be combined with the improvements
"in looms for weaving, for which a Patent was granted to me, numbered 765,
"and dated the 80th of March 1853," near the commencement of the Specifi-
cation; and I also strike out all the words commencing with the word
firstly," down to and including the words "and lastly I claim," near the end
of the Specification. And in order that the remaining claiming clause may not
be construed or understood to claim more than the combined mechanism for
actuating rotating shuttle boxes, I introduce after the word "operations," the
words of the rotating shuttle box, and I leave the description of the mechanism
now no longer claimed by me for the information of the workman.
In witness whereof, I, the said John Carter Ramsden, have here-
unto set my hand and seal, this Sixth day of July, in the year of
our Lord One thousand eight hundred and fifty-nine.

entered by the said John Carter Ramsden, as such Patentee as afore-
said, pursuant to the Statutes in that case made and provided.
WHEREAS in the Specification to the said Letters Patent
my Invention
is described as consisting in the construction, arrangement, and combination
of mechanism for, and mode of actuating the shuttle boxes, to produce the
changes of weft required by the patterns to be woven, and also as consisting
in the mode and arrangement by which changes of the weft are combined
with changes in the working of the bealds, or in a mode in which the present
improvements for effecting changes of weft in weaving may be combined with
the improvements in looms for weaving, for which a Patent was granted to me,
numbered 765, and dated the Thirtieth of March, One thousand eight hundred
and fifty-three: And whereas that part of my Invention which in my Specifi-
cation is stated to consist "in the mode and arrangement by which changes of
"weft are combined with changes in the working of the healds, or in a mode
"in which the present improvements for effecting changes of weft in weaving
may be combined with the improvements in looms for weaving, for which
a Patent was granted to me, numbered 765, and dated the Thirtieth of
March, One thousand eight hundred and fifty-three," has not turned out to
be of such value as to induce me to wish to retain the same as part of the
Invention claimed under my said Letters Patent; for which reason I wish to
disclaim, and I do hereby disclaim, the following statement of my Invention,
viz., "It also consists in the mode and arrangement by which changes of the
"weft are combined with changes in the working of the healds, or in a mode
in which the present improvements for effecting changes of weft in weaving

a Patent was granted to me, numbered 765, and dated the the Thirtieth
"of March, One thousand eight hundred and fifty-three," and also all parts
.of the Specification which relate thereto; and I wish to disclaim, and do
hereby disclaim, the separate mechanical parts of the machinery shown and
described in the said Specification.

And I alter my said Specification by striking out the five claiming clauses
at the end of the said Specification, and I insert, in place thereof, the following
words, viz., the construction, arrangement, and combination of mechanism for,
and mode of actuating the shuttle boxes, to produce the changes of weft required
by the pattern to be woven.
And I leave the description of the mechanism now no longer claimed by
me for the information of the workman.
In witness whereof, I, the said John Carter Ramsden, have hereunto
set my hand and seal, this Twenty-fifth day of November, in the year
of our Lord One thousand eight hundred and fifty-nine.
To the Commissioners of Patents for England.
I hereby grant my fiat, giving leave to the above-mentioned John Carter
Ramsden to file in the Great Seal Patent Office, with the Specification to

randum of Alteration.
