Improvements in and connected with Machinery for Threading
Glass and other Beads.
We, LEOPOLD MYERS, of Charlotte Street, Birmingham, Warwickshire, Pen
Manufacturer, and CHARLES BOSWORTH KETLEY, of 128, Colmore Row,
Birmingham, aforesaid, Engineer and Patent Agent, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention has reference to machinery and appliances for threading glass and
other beads and this invention consists of the hereindescribed improved mechanism
or means for moving the threaded beads along the threads wires or strings (with
which the needles are threaded) and so as to form alternate clear spaces on the
threads wires or strings at those parts where they have to be cut when making the
threaded beads up into bunches; and this invention further consists of improved
means for bringing fresh lengths of thread or strands into position ready to thread
the needles after those threads or strands on to which the beads have been threaded
have been removed. This invention is more particularly for use in combination
with bead threading machines of the kind described in the Specification of our
application for Letters Patent No. 19322 of A.D. 1891 but this present invention
is also adapted for use with other bead threading machines where the needles and
threads wires or other strands on to which the needles are threaded are arranged
side by side. We will describe our invention by referring to the accompanying
drawings on which
Fig. 1 represents in side elevation and Fig. 2 in plan two bead threading machines
mounted upon a long table or framework (which is represented as broken in two
places so as to get it on the drawing) and combined with one arrangement of our
said mechanism for moving the beads along the threads or wires and for forming the
alternate clear spaces thereon and for bringing fresh threads or wires into position
ready for threading;

The same letters and numerals indicate the same or corresponding parts in all
the figures.
Two of the bead threading. machines proper (such for instance as described in
the Specification of our former Patent No. 19322 of A.D. 1891 and shewn by
Figs. 1 to 8 of the drawings thereof) are arranged (see Figs. 1, 2, 3 and 4) at about
the centre of a long table or framework (marked 50) towards the ends of which
the eye ends of the two sets of needles respectively point. In each of these bead
threading machines the side frames are marked A and the roller with which the
beads revolve is marked B, the continuous leather or other band which passes
partly around the grooved roller B is marked E and the tension pulley of the band E
is marked D, the hoppers for containing the beads to be threaded are marked F
and the needles of which in each machine there are ten, are marked I. The
needles dip into the beads (not shewn upon the drawing) which are contained in
the space between the small part of the roller B and the band E and they are at
their eye ends threaded by the threads or other strands 54 on to which the beads
pass from the needles and along which the beads have to be moved. The said
table or framework 50 may be of any convenient length say fifty yards from end to
end. Carried on pins 51 (see Figs. 1, 2, 9 and 10) fixed to brackets 52 are the
bobbins or spools marked 53 (in this machine ten in number at each end of the
table or framework corresponding with the needles) containing the threads or other
strands 54 on to which the beads are required to be threaded. These threads or
other strands 54 are (as hereinafter described) unwound from the spools or
bobbins 53 at the proper times and pulled along side by side to the threading
machines proper at the middle of the table or framework 50 and then by the
attendant are threaded through the eyes of the needles 1. Extending along the
table from end to end under the said threads or strands are two thin steel or other
bands 55 and 56 which at their ends are respectively connected to the chains 57,
58, 59 and 60 passing over the chain wheels 61, 62, 63 and 64 and the other ends
of these chains are respectively connected together by rods under the table (only
one of which can be seen in Fig. 1 and is marked 65). The chain wheels 62
and 64 can revolve freely about a shaft 66 on the standard 67 at one end of the
framework and the other chain wheels 61 and 63 alternately receive by the
mechanism hereinafter described an intermittent rotary motion which gives an
alternate step by step movement to the travelling bands 55 and 56. On the upper
surface of each of these travelling bands 55 and 56 is fixed a series of sections
which travel with the bands. A part of one of these bands 56 with three travelling
sections 68 fixed to it is shewn separately in plan by Fig. 16. The travelling
sections 69 which are fixed to the band 55 are arranged alternately with the
travelling sections 68 which are fixed to the band 56 and there is a space
between each section as shewn in Figs. 17, 18, 19 and 20 where the travelling
band 55 and its travelling sections 69 are shewn shaded by cross lines and the
travelling band 56 and its travelling sections 68 are not so shaded. These
travelling sections 68 and 69 correspond in length with those parts of the threads
or strands which, when the threading is finished, are occupied by the threaded
beads 70 (see Fig. 15) and the alternate spaces between the sections 68 and 69
correspond with those clear parts of the threads 54 between the beads 70 where
the threads have to be cut and tied when making up into bunches. These
travelling sections are so constructed as to move the beads along the threads

page_text: and permit of the threaded beads being removed when required. For these
purposes we make the travelling sections in various ways one of which we will now
It will be seen that each
describe and which is illustrated by Figs. 11, 12 and 13.
of the travelling sections shewn by these figures consists of a series of soft
longitudinal ribs 71 almost close together standing up from the base 72 which is
fixed to the band 55 or 56. These ribs correspond with the spaces between the
threads or strands which latter, when the beads are being threaded as hereinafter
These soft
described, lie and are held in the spaces 73 between the ribs 71.
ribs 71 of the travelling sections can very conveniently be made of a rectangular
piece of plush, velvet, coarse corduroy or other suitable soft and pliable material
which has a holding surface and which is about the same length as the desired
travelling section and about three and a half times as wide more or less. This
piece of plush etc. is strengthened at the back by being pasted on to stout paper or
thin cardboard or linen and then bent to and fro longitudinally in a zig-zag fashion
so as to form the ribs 71 close or almost close together (as will be clearly seen by
an examination of the cross section Fig. 11*) and then fixed to this position by
being glued or otherwise fixed to the base piece 72.
.

When the said travelling bands 55 and 56 and their sections 68 and 69 are
in motion the eye ends of these needles I on to which the beads are being
threaded are kept pressed in the corresponding spaces between the ribs 71 of
the sections by means of the grooved roller T (see Figs. 3 and 4) above the
needles and under which the needles lie, and which roller T is carried by the
lever frame U which is pressed down by the springs t (see Fig. 3).
the travelling sections pass under the grooved roller T they wipe the beads off
the needles on to the threads or strands 54 and move the beads along the threads
or strands and hold the beads between the ribs 71. As before stated we prefer
for the bands 55 and 56 and their sections 68 and 69 to move forward step
by step so as to lessen as far as possible the tension on the threads or strands and
the consequent pull on the needles. Or instead of the step by step movement
the sections may move continuously. This step by step movement of the bands
and sections will be clearly understood by an examination of Figs. 17, 18, 19
and 20. In Fig. 17 the band 56 and its sections 68 and the beads held thereby as
above described have just moved towards the left hand the other band 55 and
its sections 69 meanwhile remaining stationary. Directly the sections 68 come to
rest the other band 55 and its sections 69 and the beads held thereby are moved
forward one step to the position shewn in Fig. 18 the sections 68 and band 56
meanwhile remaining stationary. Then when the band 55 and sections 69 come
to rest the band 56 and sections 68 move on another step to the position shewn by
Fig. 19 and so on each band and its sections and the beads held by the latter
moving and stopping alternately. As those travelling sections and their beads
which are at rest cause the same amount of friction on the threads or strands and
hold the threads or strands with the same tension as do the other half of the
sections which are moving forward there is no more tension on the threads or strands
and on the needles than would be caused by one section. Thus very long threads
or strands can be used and we save the time which if the threads were short would
be wasted in continually threading the needles. As each of the travelling
sections 68 or 69 moves under the roller T the section turns the latter and moves
the beads off the needles and on to and along the threads or strands as above
described but immediately any section has passed the roller the latter ceases to
Drevolve and the beads accumulate on the needles are there retained by the roller
not turning until the next section comes into contact with the roller when the
beads are by this section wiped off the needles on to and along the threads or
strands as before thus forming on the threads or strands alternately portions of
threaded beads corresponding to the length of two sections and portions of clear

several travelling sections and the beads held there by have moved along the table
or framework 50, say from the left hand one of the two threading machines proper

page_text: shewn in Figs. 1, 2, 3 and 4, until the first travelling section has arrived at the
far left hand end of the table the movement of the travelling bands and sections
ceases and the attendant then moves one of the bands say the band 55 and its
sections through only half the space between two sections as shewn in Fig. 20
thus forming between the portions of the threaded beads the clear spaces of the
threads or strands as shewn in Figs. 12, 13 and 15 where the threads or strands
have to be cut and tied when making the beads up into bunches. The threads and
the beads thereon are now removed from the travelling sections by lifting the
threads at the clear spaces between the sections as shewn by Fig. 14. The threads
or strands are then cut and tied into bunches in the usual way.
As the left hand threading machine is threading the beads and the beads are
being moved along the threads or strands towards the left hand end of the table 50
as above described the right hand machine is stationary and the threads or
strands are (by a thread gripper on one of the bands 55 or 56 hereinafter
described) being pulled down from the bobbins at the right hand end of the table
to thread the needles of the right hand machine. When the needles of this
machine are threaded the bands 55 and 56 and their travelling sections 68 and 69
are caused to move back towards the right hand step by step in the manner above
described so as to move the beads from the needles of the right hand machine
along the threads or strands towards the right hand end of the table or frame-
work 50, another thread gripper (hereinofter described) fixed at the left hand end
of the band 55 or 56 meanwhile bringing along the ends of the threads or strands
and unwinding them from the bobbins at the left hand end of the table or frame-
work 50 ready to thread the needles of the left hand machine when the bands and
sections shall have arrived as far as they can go towards the right hand.
One of the said two thread grippers (which are both alike) is shewn on an
enlarged scale by Figs. 21, 22, 23 and 24 to which we will now refer. These
thread grippers are fixed on one of the bands say 56 in front of the first and
behind the last travelling section. They each consist of two spring jaws 74 and
75 between which the threads or strands pass; the bottom one 74 of these jaws is
fixed to the band 56 and has holes 76 in its turned up ends through which the
threads or strands are threaded. The top jaw 75 is made in the form of a
spring lever fixed to side portions 77 and 78 of the bottom jaw 74 and these side
portions also form bearings for a cranked piece of wire 79 which is formed as a
side lever at 80 by which the cranked piece 79 can either be turned in one
direction so as to force the top jaw 75 down on to the bottom jaw 74 and
grip the threads or strands or by turning the lever 80 in the opposite direction
the top jaw 75 can spring up and release the threads or strands. The inner surfaces
of the jaws 74 and 75 are covered with india-rubber felt or other suitable
substance at 81 to give a firm grip on the threads when the jaws are closed
together as above described.
We will now describe an arrangement of mechanism for giving the necessary
step by step movement to the travelling bands and their sections but it is to be
understood that other forms of mechanism could be used for this purpose without
departing from the nature of our invention, or the travelling bands and their
sections can be moved along by the attendant without any mechanism at all; or as
hereinafter described the sections may be used singly without the bands for push-
ing the beads along the threads or strands; or the beads may be pushed along the
threads or strands by the attendant's hands similarly as when beads are threaded
by hand in the usual way. The said mechanism for moving the travelling bands
and sections is shewn at the left hand end of the table 50 (Figs. 1 and 2) and is
shewn on an enlarged scale by Figs. 6, 7 and 8. This mechanism is as follows:-
A shaft 82 receives rotary motion from any convenient source by a band driving on
to the step pulley 83. This step pulley enables the travelling sections to be moved
at various speeds according to the particular size of beads which are being
threaded so that the beads whether larger or smaller will be moved along the
threads or strands at about the same speed as they are threaded on to the

page_text: needles. On this shaft 82 is a bevel pinion 84 which gears with a bevel wheel 85
in the back of which is a pin 86 engaging in the vertical slot 87 in the link 88
which at its ends is jointed to the lower ends of the levers 89 and 90 which are
free to turn about the horizontal shafts 91 and 92 and at the upper ends of these
5 levers 89 and 90 are spring pawls or clicks 93 aud 94 which engage with the teeth
of the ratchet wheels 95 and 96 which are respectively fixed on to the aforesaid
shafts 91 and 92. Mounted loosely on the shaft 91 there are two bevel wheels 97
and 98 of the same size both gearing with the bevel wheel 99 fixed on the shaft 100
on the other end of which is fixed the chain wheel 63 gearing with which is the
chain 59 connected as before described to the travelling band 56. Mounted loosely
on the shaft 92 there are two bevel wheels 101 and 102 of the same size both
gearing with the bevel wheel 103 fixed on the shaft 104 on the other end of which
is fixed the chain wheel 61 gearing with which is the chain 57 connected as before
described to the travelling band 55. As the bevel wheel 85 revolves the pin 86
thercon imparts a to and fro motion to the link 88 and the levers 89 and 90 con-
nected thereto and an intermittent rotary motion is by the clicks 93 and 94
imparted to the ratchet wheels 95 and 96 and their shafts 91 and 92 alternately in
opposite directions that is to say while the shaft 91 is moving the shaft 92 is
stationary and vice versa. The stationary spring clicks 139 and 140 engaging with
the ratchet wheels 95 and 96 respectively prevent the ratchet wheels turning back
after they have been moved forward. Upon the shaft 91 and revolving therewith
there is a sliding toothed clutch 105 adapted to be moved to and fro by the
lever 106 fixed on the horizontal shaft 107 and there is a similar sliding toothed
clutch 108 revolving with the shaft 92 which can also be moved to and fro
from the said shaft 107 by the lever 109. On the shaft 107 there is also a lever 110
which by the rod 111 (see Fig. 1) lever 112 and sliding bar 113 is connected to
the lower arm of the lever 114 which turns about a fulcrum 115 fixed to the side
of the table or framework 50. This lever 114 is by the crossbar 116 connected
to another similar lever 117 at the other side of the machine (see Figs. 3, 4,
and 5) so as to enable the clutches 105 and 108 to be operated from either side of
the machine.
When the lever 114 is moved to the right hand (Figs. 1 3 and 4) the clutches 105
and 106 are respectively thrown into gear with similar clutches formed on the bevel
wheels 97 and 101 so that the intermittent motion of the shaft 91 is transmitted
through the wheels 97 and 99 to the chain wheel 63 of the chain 59, and the
intermittent motion of the shaft 92 is transmitted through the wheels 101 and 104
to the chain wheel 61 of the chain 57 thereby causing the bands 55 and 56 and the
travelling sections 68 and 69 thereon to move forward alternately step by step
towards the left hand end of the table or framework 50; and when the lever 114
s moved from the aforesaid position in the opposite direction that is towards the
eft hand so as to bring the clutches 105 and 108 respectively into gear with similar
clutches on the bevel wheels 98 and 102 this causes the wheels 99 and 103 to
evolve intermittently in the opposite direction and the travelling bands 55 and 56
nd their sections 68 and 69 to travel in the opposite direction that is towards the
ight hand end of the table or framework 50. When the lever 114 is moved into
intermediate position as shewn then the clutches 105 and 108 are not in gear
ith either of the bevel wheels and the bands 55 and 56 and their travelling
ections 68 and 69 then remain stationary.
When the beads have been moved along the threads or strands to or almost to
he end of the table or framework 50 in either direction the further movement of
he bands and the rotary motion of the threading machine parts is or may be
utomatically stopped by one of two projections fixed respectively on the end
avelling sections, coming into contact with the cross bar 116 (one of these
rojections is shewn in Figs. 3, 4 and 5 and is marked 118) which has the effect of
oving the cross bar 116 and levers 114 and 117 sideways and thus sliding along
e clutches 105 and 108 so that they do not gear with any of the bevel
heels 87, 98, 101 or 102. The same movement of the levers 114 and 117 moves

page_text: the clutch slide 119 endwise (as this clutch slide 119 is connected to the lever 114
by the pin 120) so that the incline 121 thereon acts upon the toothed clutch (which
is formed with the driving pulley 123 revolving loosely on the spindle of the
roller B) and moves this clutch 122 end wise along the shaft out of gear with the
clutch 124 which is fixed on the spindle so that the rotary motion of the roller B
and the threading of the beads is stopped. It will be seen that the movement of
the levers 114 and 117 to throw the clutches 105 and 108 into gear to run the
travelling sections either towards the right hand or towards the left hand as above
described also moves the clutch slide 119 and causes the corresponding threading
machine (Figs. 1, 2, 3 and 4) to commence to thread.
In order to lift up the eye ends of the needles of either the right or the left
hand threading machine which is not threading (as shewn on the right hand
machine in Figs. 1 and 3) and prevent their catching in the travelling sections as
the latter are moving back whilst the other machine is threading there is a sliding
bar 125 which is inclined at each end 126 and 127 (see Figs. 3 and 4) and is
connected to the lever 114 so that when this lever is moved to either the right or
left hand it moves this bar 125 end wise so that the inclined ends 126 and 127 of the
bar 125 lift the lever frame U with its roller T and the eye ends of the needles of
the machine which is stationary that is the right hand machine in Figs. 3 and 4
and allow of the corresponding lever frame U and its roller T of the left hand
machine in Figs. 3 and 4 to fall as shewn and press the eye ends of the needles
down for the travelling sections to move the beads along as above described.
+
In order to keep the threads or strands 54 taut whilst the beads are being
threaded thereon there is on each thread or strand 54 a small tension weight 128
(see Figs. 9 and 10) and in order to raise these tension weights when the needles
are being threaded the tension weights 128 are connected by cords (marked 129 at
one end of the table and 130 at the other end thereof to the levers 131 and 132
(see Fig. 1) which are jointed to the sliding bar 113 so that the act of moving the
lever 114 in one direction to start say the right hand machine Figs. 21 and 22 and
to bring down the threads to thread the needles of the left hand machine lifts the
tension weights 128 of the threads or strands of the left hand machine (thereby
taking the tension off the threads or strands) and lowers the tension weights 128 of
the right hand machine so as to keep the threads or strands taut while the beads
are being threaded thereon.
Instead of making the travelling sections 68 and 69 of soft vertical longitudinal
ribs between which the beads are held as above described and shewn by
Figs. 11, 12, 13 and 14 we may make the said travelling sections in other ways
which we will now describe. One method is illustrated by Figs. 25 and 26 where
it will be seen that projecting from the upper surface of each of the travelling
sections there are cross bars 133 preferably made of metal the upper edges of
which are notched all along at 134 at certain distances apart corresponding with
the threads or strands 54 which lie in these notches 134 so that as the travelling
sections are moved along under the threads 54 the cross bars 133 engage with the
beads on the threads or strands (see Fig. 25) and move the beads along the same.
The clear spaces where the threads are cut in making up into bunches is obtained
by the spaces between the travelling sections as aforesaid. Fig. 27 shews another
method of making the notched cross bars 133 of the travelling sections. In this
case in order to give a large area in contact with the threads or wires 54 there is a
strip of sheet metal 135 bent into a zig-zag form and fixed to the top of the
bar 133 by solder or other means. Fig. 28 shews how the said cross bars 133
may be made of wire bent into a zig-zag form and driven into the base 72 of the
section or otherwise fixed thereto. Fig. 29 shews a modified form of the cross
bars 133 herein before described and shewn in Figs. 25 and 26 but in the cross bar
shewn by this Fig. 29 there is a very narrow vertical notch 136 at the bottom of
each of the notches 134 in which notches 136 the threads lie. The object of these
narrow notches is to ensure the cross bar 133 being in contact with the beads if the
surface.over.which the sections move. is not quite level. These cross bars 133 may

page_text: be made of metal, wood, vulcanite, bone, leather or other suitable substance and
when made of leather or other substance which cannot readily be bent into the
angle form shewn in Figs. 25, 26, 27 and 29 the cross bars 133 can very readily be
fixed in the bases 72 of the sections by fitting in cross grooves 137 therein as
shewn in Fig. 30. According to another method of making the said travelling
sections we provide rows of bristles 138 to stand up from the upper surface of the
sections like a brush (see Fig. 31) so as to move the beads along the threads. In
combination with the rows of bristles we may use one or more of the cross bars 133
at the ends or other parts of the travelling sections so as the better to keep the
threads or strings the proper distances apart.
Instead of the travelling sections being mounted alternately on two separate
bands so as to obtain a step by step movement of the said sections as above
described and shewn in Figs. 1, 2, 3, 4, 5, 11*, 12, 13, 16, 17, 18, 19 and 20 the
whole of the said sections may be mounted upon the same band and move
continuously but in this case as there is more tensile strain upon the threads 54
much shorter threads must be used. Figs. 32, 33 and 34 shew a single bead
threading machine with the travelling sections arranged to move continuously. In
this arrangement the travelling sections 68, 69 are each fixed to one and the same
endless leather or other flexible travelling band which in this machine is marked 150
and which passes round the slowly revolving polygonal drum 151 at one end of the
table or framework 50 and round a similar drum at the other end thereof so that a
slow forward motion is transmitted to the band 150 and the travelling sections
thereon. Each of the travelling sections is divided across into eight or other
numbers of sub-sections of the same length as the sides of the polygonal drum 151
so as to pass around the same, and in order to ensure the sub-divisions of the
sections coming exactly on to the sides of the polygonal drum 151 there may be a
peg 152 standing up from ench side which engage in corresponding holes 153 in the
band 150. The lever 11 through the rod 113 actuates a clutch or similar
contrivance for stopping starting or reversing the motion of the said polygonal drum
at the other end of the table or framework and by means of the sliding bar 154
connecting the lever 114 to the clutch slide 119 the roller B of the bead threading
machine portion is stopped and started with the travelling band 150, as in the
arrangement with the two bead threading machines hereinbefore described.
Instead of using any travelling bands or mechanism for moving the travelling
sections along the table or framework 50 as above described, the bands and
mechanism may be dispensed with and the travelling sections which are then
separate from each other can be moved by hand along the said table or frame-
work 50 under the threads or strings and move the beads along the same and form
in the manner above described the alternate clear spaces for bunching. This is
shewn by Fig. 35 where the table 50 and one of the travelling sections 72 such as
represented by Fig. 26 are shewn in cross section. The said travelling sections 72
are pushed under the eye ends of the needles one after the other from the back of
the machine in the direction of the arrow in Fig. 32 the cross bars 133 pushing
the beads off the needles and on to and along the threads or strands as above
described. In order to ensure the said sections 72 travelling along the table or
framework in a straight line there are two strips 155 and 156 (see Fig. 35) of wood
or other substance fixed on the upper surface of the table or framework 50 so as to
form a guide for the sections as they are being pushed along. In order to form
the said clear spaces on the threads or strands where they are cut and tied in
bunching the beads, the base 72 of each of the sections has to be made about equal
in length to the sum of one of the portions 70 of threaded beads and one of the
clear portions, and the cross bars 133 are only fixed on that portion of the base
which will be occupied by the portion 70 of the threaded beads. When any one of
the travelling sections is pushed under the needles as aforesaid the inclined end 157
of a bar 158 which is fixed to the side of the section 72 (see Figs. 26 and 35) in
passing under a roller 159 on the lever frame U, lifts the same and the grooved
roller T to about the position shewn in Figs. 32 and 35 so that the needles I will

page_text: then be free of the bar 160 which is fixed to the base of the threading machine
portion (see Fig. 32) and the beads can pass down the needles on to the threads or
strings 54. This bar 158 keeps the roller T raised all the time the bars 133 of
any section are moving the beads off the needles but just before the last cross
bar 133 on any of the sections 72 arrives at the needles the inclined end 161 of the
bar 158 (see Fig. 26) allows the lever frame U and its roller T to drop far enough
for the roller T to press the needles against the fixed bar 160 and thus cause the
beads to accumulate on the needles and prevent any beads passing off the needles
while that back portion 162 of the base 72 corresponding with the clear portions
on the threads is passing under the needle eyes. Directly the next section 72 is
pushed under the machine in the direction of the arrow Fig. 32 as above described
and the incline 157 thereon lifts the lever frame U and roller T, the threading
proceeds as before.
When the travelling sections are furnished with the notched crossbars 133 these
bars are not suitable for turning the grooved roller T as are the sections 68 and 69
made with soft longitudinal bars, and therefore the roller T has to be caused to
revolve by some other means as by a continuous band or cord driving off the
pulley 163 (Fig. 35) on the shaft b¹ on to the pulley 16+ fixed on the spindle of the
grooved roller T.
The accompanying drawings illustrate what we consider to be the best methods
of carrying our said invention into practice but it is to be understood that our said
invention is not limited to the precise details shewn.
Although we prefer to arrange the travelling sections at certain distances apart
as above described so as to form the alternate clear spaces on the threads or
strands 54 where they have to be cut and tied in making the beads up into bunches
yet it is to be understood that without departing from the nature of this invention
the travelling sections may be arranged close together so as not to form the said
clear spaces but to make the beads continuous along the threads or strands and the
beads can then be divided afterwards as is now done when they have been threaded
by hand.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In combination with a bead threading machine in which the needles are
arranged side by side, the employment of the travelling sections arranged to move
or to be moved along the threads or strings (with which the needles are threaded)
and to engage the beads so as to move the beads along the threads or strings sub-
stantially as herein before set forth.
2. In combination with a bead threading machine in which the needles are
arranged side by side, the employment of the travelling sections arranged to move
or to be moved along the threads or strings (with which the needles are threaded)
and to engage the beads so as to move the beads along the same and form the
alternate clear spaces thereon where they have to be cut and tied in bunches,
substantially as herein before set forth.
3. In combination with a bead threading machine in which the needles are
arranged side by side, the employment of two sets of the travelling sections arranged
to move forward by a step by step movement along the threads or strings (with
which the needles are threaded) and to engage the beads so as to move the beads
along the same and form the alternate clear spaces thereon where they have to be
cut and tied in bunches substantially as hereinbefore set forth.
4. In combination with a bead threading machine in which the needles are
arranged side by side, the employment of the separate travelling sections (Figs. 26,
27, 28, 29, 30, 31) adapted to be moved forward one after the other under the
needles and threads and to engage the beads so as to move the beads along the
threads and form the alternate clear spaces thereon where they have to be cut and
tied in bunches, substantially as hereinbefore set forth.

5. The construction of the travelling sections in any of the several ways
stantially as set forth for moving the threaded beads along the threads strings or
wires.
6. In combination with a bead threading machine in which the needles are
arranged side by side the devices for causing the beads to move continuously down
to the needle eyes and on to the threads only when one of the travelling sections
is in position for moving the beads off the needles on to and along the threads, and
for maintaining the heads on the needles when any travelling section has passed
the needle eyes until the next travelling section comes into position, consisting of
the revolving roller T (Figs. 32 and 33) under which the needles pass and which
is lifted by an incline 157 on each section (Fig. 26) thereby allowing the needles
to rise off a bar 160 (Fig. 32) against which when any travelling section has passed
the needle eyes the needles are pressed by the roller T until the roller T is lifted
by the next travelling section.'
7. In combination with a bead threading machine in which the needles are
arranged side by side and the beads are moved on to and along the threads by
travelling sections having a step by step movement as herein set forth the
mechanism for imparting the said step by step movement to the travelling bands 55
and 56 on which the two sets of travelling sections are respectively fixed and for
reversing the said movement arranged and operating substantially as herein
described and illustrated by Figs. 1, 2, 6, 7 and 8 of the accompanying drawings.
8. The combination of two bead threading machines having their needles arranged
side by side and pointing in opposite directions, with a travelling band or travelling
bands furnished with travelling sections adapted to move to and fro and engage
the beads of one machine and move these beads off the needles and on to and along
the threads or strings whilst a gripper on the travelling band is bringing along
from, bobbins the threads or strings for threading the needles of the other machine
substantially as hereinbefore set forth.
