Sealed the 18th July 1862, and dated the 1st February 1862.
PROVISIONAL SPECIFICATION left by the said William Clark at the
Office of the Commissioners of Patents, with his Petition, on the 1st
February 1862.
I, WILLIAM CLARK, of 53, Chancery Lane, in the County of Middlesex,
Engineer and Patent Agent, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR THE MANUFACTURE OF
FESTOONED EDGING OR MATERIAL," to be as follows:-
This Invention relates to an apparatus for the manufacture of festooned
edging or material. The material I employ consists of ribbon or galloon
cut according to the design to be produced; this is previously stiffened or
sized, and in this state introduced into the machine; and in order to complete
the festooning or ornamental form of the cutting it is necessary to wind the
thread on the galloon, or even on cardboard, and cross it. Lastly, the material.
is washed in order to remove the size or. starch, and afterwards dried and
pressed.

page_text: The following is a description of the apparatus for manufacturing the same:-
1st, the frame of the machine, Fig. 2, is open at A, B, C, D, in this opening
is a small rectangular part F, F, also provided with an opening E; the ends
of said rectangular parts slide in the sides of the frame in such manner as to
allow of its motion to and fro horizontally, being guided by two conductors
K', K', at its two ends. Two rollers are mounted in supports i, i, on the frame,
the one at the back for winding on the galloon before its introduction to the
machine, the other at the front part for winding on the finished work on its
leaving the machine. On the small rectangular piece at the front of the
machine there is a nut the base of which is fixed on the frame s, Fig. 2, and
the top of which is formed in two parts hinged together and intended to
receive a screw, Fig. 12, supported by the rectangutar part and disposed under
the machine for the purpose of moving the apparatus in one direction or the
other, as required; when the nut has traversed the whole of the screw
thread it is opened on its hinge in order to return the apparatus to the starting
point for recommencing the operation.
2ndly, I employ an arrangement, represented at Fig. 13, for winding on the
cotton, which is constructed of a copper tube of about an inch in diameter
and of a length proportionate to that of the frame.. and the dimensions of the
apparatus, and for greater clearness I will describe each part, its action,
and position. On a tube a, b, c, d, Fig. 3, I place another tube e, f, g, h, of
about half its length, mounted loosely so as to slide on the longer one when the
latter is fixed. At one end of the movable tube is fixed a round plate carrying
a bobbin R, and also a rod v, v, parallel to and of equal length to the bobbin K.
It is evident by this arrangement, 1st, that if the galloon leaves the large fixed
tube in a state of tension,-2ndly, if thread be wound on bobbin K and the end
be passed over the parallel rod and attached to the galloon at M (see the
threads), 3rdly, if a toothed wheel be fixed to the end of small tube at
N; N, and 4thly, if the bobbin be rotated by means of the gearing, the
thread attached to the galloon o will be wound round it. The galloon,
separately seen in Fig. 4, is held firm by the tension exerted on the two
rollers i, i, on the frame described at Fig. 1 of the Drawings.
3rdly, the apparatus consists of a rectangular part, Fig. 5, on which are
mounted two levers G, one only being represented for greater clearness (also
seen in Fig. 1.) to the ends H, H, of which cords are attached, passing over
pullies v, v, Fig. 6; the ends of these cords i, i, are connected to shuttle drivers;
each lever thus mounted actuates two shuttle drivers which are connected
to the ends of diagonal cords; hence the two shuttles M, M, Fig. 1, move
crosswise with the threads they contain.

page_text: 4thly, the thread is wound on at A, A, Fig. 15, which also shows the rod for
conducting the cotton or thread from bobbin B, B, also showing shuttles G, G,
crossing it, and the points u, u, see Fig. 2, for returning the threads to position,
in connection with the apparatus, Fig. 7, to be hereafter described.
5thly, I dispose two shuttles at A; B, Fig. 9, and M, M, Fig. 1, and four
shuttle drivers A, B, Fig. 10, and i, i, Fig. 1; the four shuttle drivers are simply
four square blocks of wood, each having one end acting on the shuttles in
small uprights and intended to receive the cords of levers, Fig. 10. The shuttles
are carried by two hollow 'blocks of wood A, B, Fig. 8, and are constructed of
a piece of iron having the two ends raised, as at A, B, Fig. 9; in the centre
they have two upright pieces provided with holes G; the ends are furnished
with two holes receiving the ends of a spindle forming a bobbin for wind-
ing on the thread; they have also one straight side and one side turned
down in order to afford space for a flat spring i, i, Fig. 9, under which the
thread passes after running through the holes in the centre upright pieces, the
thread being thus submitted to pressure, which always keeps it stretched.
The shuttles and shuttle drivers are furnished at their base with guides for
sliding on the table K, K, K, of the apparatus, Fig. 1, which is provided with
grooves for receiving them.
6thly, the screw B, B, Fig. 12, being furnished at one side with the hinged
part A on base T, causes the small rectangular part of the frame to slide by its
pressure thereon, its gearing s, s, also drives wheel N, Fig. 3, so as to wind
on the cotton in connection with a skew-toothed wheel L, L, with 4 or 6 teeth.
It should be observed that the firmness of the winding depends on the pitch
of the screw and the number of teeth of wheel L.
7thly, A, B, Fig. 11, represents the driving shaft, having two cams or.
projections C, C, for acting on the inclined teeth of wheel L, Fig. 12; also
having two other projections i, i, one for acting on mechanism for regulating
the motion of screw, Fig. 16, and the other acting on a part, Fig. 7, for raising
or lowering the iron pins C, C, Fig. 7, and u, u, Fig. 15, for drawing and
stretching the shuttle threads when winding on the cotton, as herein-before
described and represented at Fig. 3.
-8thly, the part for containing the iron rods used for raising and separating
the shuttle threads, Fig. 7, before méntioned, consists of two pieces of wood
fixed to the shuttle carrying platform A, B, C, D, Fig. 1, and hinged to
two fixed blocks of wood K, K, Fig. 7, having a cross piece i, i, 'to the
centre of which are fixed two iron pins C, C, thus, if said cross piece is raised
or lowered, and with it the wires, at a given moment when the threads from

page_text: the bobbins are crossed' and the thread is wound, the threads will be separated
to a suitable extent. The two lovers, moved by the cams i, i, Fig. 11, as
before mentioned, are intended, one for the mechanism A, B, Fig. 16, and the
other that represented at O, O, Fig. 7, which lever acts on a cord for returning
the cross piece to position by means of wires, and when the eccentric which
works the lever has freed itself a spring presses down said cross. piece (see
levers, Fig. 2, at the side of the machine)..
The following is a description of the different parts of the apparatus com-
bined: A, B, C, D, platform, terminated by a foot having an opening M, N, O, P.;
in this platform are four grooves K, K, K, K, in which slide the shuttle and
shuttle drivers. The opening in the foot is intended for receiving the conductor K',
connected to the small rectangular part F, F, Fig. 2, in front of the nut and
also in front of said rectangle. Behind this is placed the part. represented at
Fig. 5, for supporting the levers acting on the shuttle drivers, as before
described; at the back of each shuttle driver there is a weighted cord g for.
returning it to its normal position. In the centre of the table of the machine
is a space in which is placed the apparatus for winding the cotton, represented
at Fig. 1, E, E, and, also at Fig. 3.; the part represented at Fig. 12 is placed:
underneath, so that it gears with the part seen at Fig. 3 for winding the:
cotton. The apparatus is provided with à crank shaft z, z, to be hereinafter
described, as also a screw 22, 22; Fig. 1, already described with reference..to
Fig. 12.
'I will now describe the crank shaft represented at Figs. 13 and 14. In a
block of wood of about 1½ inches square and of any suitable length, is a
groove, seen in Fig. 14, in which slides a plate, Fig. 13, furnished with two
teeth or cams having a space between them equal to that between the levers
G, G, Fig. 1, in such manner that this plate may move to and fro and so
change the positions of the two 'cams by means of radial arms B, B, B, B,
Fig. 14, one arm being connected to the plate K by rod M. From this
arrangement it will be understood that if rotary motion be imparted to the
crank, and the arms B, B, B, B, perform half a revolution only, their motion
being limited by stops x, the plate and cams will assume different positions
in such manner as to act first on one lever and then on the other, for the
purpose of moving and crossing the shuttles and shuttle drivers, as bèfore
mentioned.
I will now describe the action of shaft z, z, Fig. 1:-A cam y acting on
lever H produces the crossing of the shuttles and shuttle drivers, the threads
being crossed on the galloon Z. When the shuttle drivers return to their

page_text: original position, and the space in the centre of the platform remains free, the
cams z¹, zl, next turn the wheel a¹, causing the gearing B' to gear with N',
thus the cotton-winding apparatus turns round the galloon at A¹ and the
operation is completed; but it should be remarked that in order that the
shuttles pass above the opening between the fixed tube and the support which
conducts the thread to the winding apparatus, the shuttle drivers must guide
the shuttles on the other side of the opening in the platform, and that the
support or iron rod conductor of the cotton or thread be in a perpendicular
position above the shuttles. It has been before mentioned that the shuttle
drivers are returned to position by means of a second lever which is actuated
by a second cam of the crank shaft working two other shuttle drivers which
also cross the shuttles, the shaft continuing its rotation (see apparatus Fig. 7),
being set in motion by means of cam s¹, which raises and returns the wires of
the cross piece to position, as before described; on the other hand the cam o
raises the gearing, Fig. 16, while the cams z¹, ¹, again act as before for the
purpose of winding the cotton for a fresh operation.
The Invention thus consists of crossing the threads on the edges of the
fabric for producing the effect desired. In Fig. 17, a, a, is a plan of the
shuttles-and shuttle drivers; B, B, shaft with two pivots at right angles to.
two rods c, c, having four uprights o, 0, 0, 0; r, spring for keeping the appa-.
ratus raised; tt, shaft of the apparatus ;. v, v, two levers, hinged together,
connected to part c, c, c, c, for the purpose of moving it; e, e, eccentric on
the shaft pressing on one of the levers v,.v, for the purpose. of lowering the
apparatus c, c, c, which is kept constantly raised by the spring. The eccentric
is placed in position so that the; uprights o, 0, 0, 0, are lowered during the
throw of the shuttles, & then rise for the purpose of retaining them &
tightening the threads; i, cam on the shaft; j,-hooked lever; m, upright
hooked to lever j, which acts at each revolution of the machine on the hooked
end n of the lever each time the apparatus is raised by the spring, which
allows of the cam i passing as before seen. Thus it is evident that if from.
any cause the apparatus does not rise so that the shuttles are not entirely free
to traverse, the machine will be stopped, which prevents accidents and. allows
of the application of steam power for driving the apparatus.. Thus the Inven-
tion consists of the improved apparatus herein-before described and represented
for the manufacture of festooned material applicable for forming edgings, flowers,
& all kinds of embroidery patterns..

by the said William Clark in the Great Seal Patent Office on the 30th
July 1862.
.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
CLARK, of 53, Chancery Lane, in the County of Middlesex, Engineer and
Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Iler Letters
Patent, bearing date the First day of February, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Clark, Her special licence, that I, the said William Clark,
my executors, administrators, and assigns, or such others as I, the said
William Clark, 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 Invention for "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR THE MANUFACTURE OF FESTOONED EDGING OR
MATERIAL," a communication from abroad by Mr. Jean Joseph Basset, Pro-
prietor, of 29, Boulevart Saint Martin; Paris; upon the condition (amongst
others) that I, the said William Clark, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Invention, and
in what manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Clark, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, reference being had to the Sheets of Drawings hereunto annexed,
and to the letters and figures marked thereon (that is to say):
This Invention relates to an apparatus for the manufacture of festooned
edging or material. The material I employ consists of ribbon or galloon cut
according to the design to be produced; this is previously stiffened or sized,
and in this state introduced into the machine, and in order to complete and cause
it to retain the festooning or ornamental form of the cutting, it is necessary
to wind thread on the galloon (or it may even be on cardboard,) and cross it;

page_text: lastly, the material is washed in order to remove the size or starch, and after-
wards dried and pressed. The following is a description of the apparatus for
manufacturing the same, which is represented in the Drawings annexed:-
First, the frame of the machine, Fig. 2, Sheet 1, is open at A, B, C, D;
in this opening is a small rectangular part F, F, also provided with an opening
E. The ends of said rectangular part are furnished with slides running in the
sides of the frame in such manner as to allow of its motion to and fro hori-
zontally, being guided by two guides K, K; at its two ends two rollers are
mounted in supports i, i, on the frame, the one at the back for winding on the
galloon before its introduction to the machine, the other at the front part for
winding on the finished work on its leaving the machine. On the small
rectangular part at the front of the machine there is a nut, the base of which
is fixed to the frame s, Fig. 12, and the top of which is formed of two parts
hinged together, and intended to receive a screw, shown at Fig. 12, supported
by the rectangular part, and disposed under the machine for the purpose of
moving the apparatus in one direction or the other as required. When the
nut has traversed the whole of the screw thread, it is opened on its hinge in
order to return the apparatus to the starting point for recommencing the
operation.
Secondly, I employ an arrangement, represented at Fig. 3, for winding on
the cotton, which is constructed of a copper tube of about half an inch in
diameter, and of a length proportionate to that of the frame, and the dimen-
sions of the apparatus; and for greater clearness I will describe each part, as
also its action and position. On a tube a, b, c, d, I place another tube.
e, f, g, h, of about half its length mounted loosely so as to slide on the longer
one when the latter is fixed. At one end of the movable tube is fixed a
round plate carrying a bobbin k, and also a rod v, v, parallel to and, of equal
length to the bobbin k. It is evident, by this arrangement, 1st, that if the
galloon leaves the large fixed tube in a state of tension,-2ndly, if thread be
wound on bobbin k, and the end be passed over the parallel rod, and attached
to the galloon at M. (see the threads), 3rdly, if a toothed wheel be fixed to
the end of small tube at N, N,—and, 4thly, if the bobbin be rotated by means
of the gearing, the thread attached to the galloon O will be wound round it.
The galloon separately seen at Fig. 4 is held firm by the tension exerted on
the two rollers i, i, on the frame described in Fig. 1 of the Drawings.
Thirdly, the apparatus consists of a rectangular part, Fig. 5, on which are
mounted two levers G, one only being represented for greater clearness, as also
seen in Fig. 1, to the ends H, H, of which are attached cords passing over

page_text: pullies v, v, Fig. 6; the ends of these cords i, i, are connected to shuttle
drivers, which are connected to the ends of diagonal cords; hence the two
shuttles M, M, Fig. 1, move. diagonally or crosswise to each other with the
threads they contain.
are con-
B, Fig. 9; in
...Fourthly, the thread A, A, is wound on at Fig. 5, which also shows the
rod for conducting the cotton or thread from bobbin B, B, also showing
shuttles G, G,, crossing it, and the points u, u, for returning the threads to
position in connection with an apparatus, Fig. 7, to be herein-after described.
Fifthly, I dispose, two shuttles A, B, Fig. 9, and M, M, Fig. 1, and four
shuttle drivers A, B, Fig. 10, and i, i, Fig. 1. The four shuttle drivers are
simply four square blocks of wood, each having one end acting on the shuttles
in small uprights,, and intended to receive the cords of levers, Fig. 10. The
shuttles are carried by two hollow. blocks of wood A, B, Fig. 8, and
structed of a piece of iron, having the two ends raised as at A,
the centre they have two upright pieces provided with holes G.. The ends. 1
are furnished with two holes receiving the ends of, a spindle forming a bobbin.
for winding. on the thread; they have also one straight. side, and, one side.
turned down in order to afford space for a flat spring i, i, Fig. 9, under which,
the thread passes after running through the holes in the centre upright pieces,
the thread being thus submitted to pressure which always keeps it. stretched.
The shuttle and shuttle drivers are furnished at their base with guides for.
sliding on the table k, k, k, of. the apparatus, Fig. 1, which is provided with
grooves for receiving them.
:
Sixthly, the screw B, B, Fig. 12, being furnished at one side with a hinged.
nut A on base I, causes, the small rectangular part of the frame to slide by its s
pressure thereon; its gearing s, s, also drives wheel N, Fig. 3, so as to wind
on the cotton in connection with a skew toothed wheel L, L, with 4 or 6
teeth. It should be observed that the fineness of the winding depends on the
pitch of the screw, and the number of teeth of wheel L.
Seventhly, A, B, Fig. 11, represents the driving shaft, having two cams or
projections C, C, for acting on the inclined teeth. of wheel L, Fig. 12; also
having two other projections 1, 1, one for acting on mechanism for regulating
the motion of screw, Fig. 16, and the other acting on the part, Fig. 7, for
raising or lowering.the iron pins C, C, Fig. 7, and u, u, Fig. 15, for drawing
and stretching the shuttle threads when winding on the cotton, as herein- 3
before described and represented at Fig. 3.
Eighthly, the part. for containing the iron rods used for raising and sepa-
rating the shuttle threads, Fig. 7, before. mentioned, consists of two pieces of

page_text: wood fixed to the shuttle-carrying platform A, B, C, D, Fig. 1, and hinged
to two fixed blocks of wood k, k, Fig. 7, having a cross piece u, Fig. 7, to the
centre of which are fixed two iron wires C; C; thus if said cross piece is
raised or lowered, and with it the wires at a given moment when the threads
from the bobbins are crossed while the thread is being wound, the threads will
be separated to a suitable extent. The two levers moved by the cams i, i,
Fig. 11, as before mentioned, are intended to operate, the one the mechanism
A, B, Fig. 16, and the other that represented at o, o, Fig. 7, which lever acts
on a cord for returning the cross piece to position by means of wires, and
when the excentric which works the lever has fixed itself, a spring presses
down said cross piece (see levers u, u, Fig. 2, at the side of the machine.)
The following is a description of the different parts of the apparatus com-
bined. A, B, C, D, platform terminated by a foot, having an opening
M, N, O, P. In this platform are four grooves k, k, k, k, in which slide the
shuttles and shuttle driver. The opening in the foot. is intended to receive
the conductor k, connected to the small rectangular part F, F, Fig. 2, in
front of the nut, and also in front of said rectangle. Behind this is placed the
part represented at Fig. 5, for supporting the levers acting on the shuttle
drivers as before described. At the back of each shuttle driver there is a
weighted cord 9 for returning it to its normal position. In the centre of the
table of the machine is a space in which is placed the apparatus for winding
the cotton represented at Fig. 1, E¹, E', as also at Fig. 3. The part repre-
sented at Fig. 12 is placed underneath, so that it gears with the part seen at
Fig. 3, for winding the cotton. The apparatus is further provided with a
crank shaft z, z, to be herein-after described, as also a screw 23, 22, Fig. 1,
already described with reference to Fig. 12.
I will now describe the crank shaft represented at Figs. 13 and 14. In the
block of wood of about one and a half inches square, of any suitable length, is
a groove seen in Fig. 14, in which slides a plate Fig. 13, furnished with two
teeth or cams, having a space between them equal to that between the
levers G, G, Fig. 1, in such manner that the plate may move to and fro, and`
so change the positions of the two cams by means of radial arms B, B, B, B,
Fig. 14, one arm being connected to the plate k by rod M. From this
arrangement it will be understood that if rotary motion be imparted to the
crank, and the arms B, B, perform half a revolution only, their motion being
limited by stops x, x, the plate and cams will assume different positions in'
such manner as to act first on one lever and then on the other, for the purpose
of moving and crossing the shuttles and shuttle drivers as before mentioned:

page_text: .
I will now describe the action of shaft z, z, Fig. 1. A cam y acting on
lever H, produces the crossing of the shuttles and shuttle drivers, the threads
being crossed on the galloon . When the shuttle drivers return to their
original position, and the space in the centre of the platform remains free,
the cams 2¹, 2¹, next turn the wheel a¹, causing the gearing B¹ to gear with N',
thus the cotton winding apparatus turns round the galloon at A', and the
operation is completed; but it should be remarked, that in order that the
shuttles pass above the opening between the fixed tube, and the support
which conducts the thread to the winding apparatus, the shuttle drivers must
guide the shuttles on the other side of the opening in the platform, and that
the support or iron rod conductor of the cotton or thread shall be in a per-
pendicular position above the shuttles.
It has been before mentioned that the shuttle drivers are returned to
position by means of a second lever, which is actuated from the crank shaft by
a second cam, while two other shuttle drivers, which also cross the shuttles,
(the shaft continuing its rotation (see. apparatus, Fig. 7), being set in motion
by means of cam s', which raises and returns the wires of the cross piece to
position as before described. On the other hand the cam o¹ relieves the
gearing Fig. 16, the cams ¹, ¹, again act as before for the purpose of winding
the cotton in a further operation. The Invention thus consists in crossing
the threads on the festooned edge of the fabric or material to produce the effect
desired.
In Fig. 17, a, a, is a plan of the shuttles and shuttle drivers; B, B, shaft,
with two pivots at right angles to two rods c, c, having four uprights o, 0, 0, 0 ;
r, spring for keeping the apparatus raised; t, t, shaft of the apparatus; v, v,
two levers hinged together, connected to parts c, 'c, c, c, for the purpose of
moving it; e, e, eccentrics on the shaft, pressing on one of the levers v, v, for
the purpose of lowering the apparatus c, c, c, which is kept constantly raised
by the spring. The excentric is placed in position, : so that the uprights 0, 0,
o, o, are lowered during the throw of the shuttles, and then rise for the purpose
of retaining them, and tightening the threads; i, cam on the shaft; j, hooked
lever; m, upright, hooked to lever j, which acts at each revolution of the.
machine on the hooked end n of the lever each time the apparatus is raised
by the spring, which allows of the cam i passing as before scen. Thus it is
evident that if from any cause the apparatus does not rise so that the shuttles
are not entirely free to traverse, the machine will be stopped, which prevents
accidents, and allows of the application of steam power for driving the
apparatus.

page_text: As before mentioned, I may either use two or three threads in the manu-
facture of the festooned edging or material; in the latter case, one winds on
the edging, while the two others are crossed by means of two shuttles sliding
horizontally, but I prefer to use two threads, which arrangement is represented
in Sheet 2 of the Drawings, in which one of the threads winds on the edging,
and the other winds on the thread by means of a shuttle having a circular
motion imparted to it. The first thread wound on the edging is carried by a
rigid rod, having an intermittent circular motion, during the intermissions of
which the second thread is wound on the first. This is effected by means of
jointed toothed segments carried on a ring, and of which I claim the applica-
tion in the manufacture of other kinds of embroidery. This ring has also an
intermittent circular motion, by which means the rigid rod when gearing with
the segments, winds the thread round the edging or ribbon, or other trimming,
according to the pattern to be made. The intermittent movement of the rod
and toothed segment is obtained by means of cams of the form of a "Maltese
cross," gearing with other cams of suitable form, which act on each other in
such manner that the intermissions of motion of the segment takes place
during the motion of the rod, and vice versa.
Sheet 2 of the Drawing annexed represents this modification of the machine,
Fig. 1 being an elevation partly in section; Fig. 2, a plan; Fig. 3, a plan
and edge view of the toothed segment forming the principal part of the appa-
ratus; Fig. 4, shows a separate view of the cams engaging in another cam of
the form of a "Maltese cross;" while Fig. 5 shows the position of the two
threads on the edging in course of manufacture. The same letters of reference
indicate the same parts in the several Figures seen in different positions.
a, frame of the machine; b, driving shaft, furnished with a crank; c, c¹,
bevil wheels fixed on the driving shaft; d, d' bevil wheels of similar diameter
gearing in c, c¹; e, shaft, driven by wheel d¹, having a cam f¹; 9, g¹, cams in
the form of a "Maltese cross," gearing with cams f, f¹; h, toothed wheel,
carried by an endless screw i which it rotates, this wheel h receives an inter-
mittent motion from cam g on said screw, which it communicates to pinion j,
and thence to a rigid rod k carrying the thread of the toothed segment before
described;, toothed wheel, fixed on the shaft of cam g³, gearing with and
thereby communicating an intermittent motion to pinion m, and thence to a bevil
wheel n fixed on the same shaft; o, bevil wheel, receiving motion from wheel n,
and communicating it to a toothed wheel p on same shaft, carried by a horse-
shoe support on the frame; 9, segmental ring of teeth gearing with
P, and
carried by two metal slide rods; s, hinged segments of ring q, for receiving

supplying thread thereto; x, hollow tubes serving to guide the galloon or
ribbon for forming the festooned material; y, bearing fixed on table z, by
.which the whole of the machine is moved when the screw is rotated by
'wheel h.
Having described the nature of this Invention, and the manner of per-
forming the same, I declare that what I claim as the Invention to be protected
by the herein-before in part recited Letters Patent is, the machinery herein-
before described and represented in the Drawings annexed for the manufacture
of festooned edging or material, as also the various parts of which it is composed,
especially the segment of teeth herein-before described.
I also claim the application of said toothed segment to other machines for
the manufacture of different kinds of embroidery edging which have hitherto
