PROVISIONAL SPECIFICATION.
Certain Improvements in Bead Threading Machinery.
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 to be as follows:-
This invention has reference to bead threading machinery and consists firstly of
the hereindescribed improved means for threading the beads on to the needles.
In carrying out this part of our invention we provide a horizontal cylinder or
partial cylinder the ends of which are closed and which is suitably supported so as
to remain stationary. Passing longitudinally through this cylinder there is a
revolving spindle which may form the axis of the cylinder and mounted upon this
spindle there is a circular brush which is by preference rather smaller in diameter
than the internal diameter of the cylinder. The upper portion of the cylinder is
open and into this open part the beads are fed continuously from a hopper or
trough or by other means so as to fill the cylinder and the space between the
bristles of the brush. Dipping into the upper open part of the cylinder there are
needles arranged in a row side by side the ends of these needles which dip into the
cylinder being by preference hooked and the needles mounted so as to remain
stationary for instance as described in the Specification of our Letters Patent
No. 19322 of A.D. 1891. When the said spindle and brush revolve the beads are
carried round with and by the brush inside the cylinder and thus threaded on to
the needles which dip into the beads. The beads are moved along the needles by
auy convenient means such for instance as described in the Specification of our
previous Letters Patent above referred to.
Instead of employing a revolving brush to move the beads round in the said
cylinder on to the needles as above described we may provide on the said spindle
for the same purpose a boss or hub made with projecting vanes wings or beaters
for instance like a fan or centrifugal pump which move the beads round continuously
and thread them on to the ends of the needles the said needle ends being set so as
not to touch the said vanes wings or beaters; or upon the said spindle we may
provide discs at a short distance apart or projecting arms or other means which
when the spindle is revolving will move the beads round continuously in the
cylinder and thread them on to the needles.
The second part of this invention consists of the hereindescribed improved means
for properly delivering the beads off the needles (which are arranged at certain
distances apart side by side) on to the threads or wires along which the beads are
moved by short boards or sections made with upwardly projecting cross bars having
vertical notches or slits in which the said threads or wires lic as described in the
Specification of our Letters Patent No. 21192 of A.D. 1892. As the said sections
are moved successively under the eye end parts of the needles from the back of
the machine it is important that only sufficient beads should be allowed to pass
between the said cross bars of the sections as will fill in the spaces between these
cross bars and that the beads should be prevented from riding on the top of the
cross bars otherwise the tension on the threads will be increased and the threads
will be liable to break or the needles pulled out of the machine. In carrying out

page_text: this part of our invention we employ a guide bar for the eye end portions of the
needles which guide bar is by preference provided with side arms jointed to the
frame of the machine and is arranged in a horizontal position immediately above
the tops of the cross bars of the sections and so as to rest upon the said cross bars
and if desired be lifted and allowed to fall slightly by each cross bar as they pass
underneath the guide bar. The upper surface of the said guide bar is made with
grooves corresponding with the needles and with the notches or slots in the cross
bars of the moving sections these grooves in the guide bar being large enough to
allow of the beads passing down the needles easily; immediately in front of the
guide bar and above the tops of the cross bars of the moving sections I provide
a cut off bar which by side arms is jointed to the frame of the machine so as
to be capable of moving up and down. When this cut off bar is in its lowest
position its bottom edge rests on the needles or on a suitable stop so as to
prevent the beads passing along the needles out of the grooves of the guide
bar but when this cut off bar is lifted then the beads are free to pass along the
needles out of the grooves of the guide bar. This cut off bar has an inclined
portion underneath which is acted upon by the cross bars of the moving sections
so that the cut off bar is lifted by every cross bar except the first of each
section.
The mechanism above described operates as follows:-When there is no section
being pushed under the needles from the back of the machine so as to lift the cut
off bar the latter being in its lowest position blocks the beads on the needles at a
short distance above their eyes. As the section is moved along this first cross bar
fails to lift the cut off bar as the cross bar is cut away so as not to act upon the
incline of the cross bar but when this first cross bar has moved for a short distance
in front of the guide bar the cut off bar by the next cross bar of the section
raised and the beads immediately pass down the needles until they come in
contact with the first cross bar and they continue to thus move down the
needles until the second cross bar arrives underneath the front side of the
guide bar when the cut off bar falls and prevents any more beads passing thus
having allowed just sufficient beads to pass the guide bar as will fill the space
between the two cross bars of the section; then after this second cross bar has
moved for a certain distance in front of the guide bar the cut off bar is again
lifted and another measured quantity of beads allowed to pass the guide bar
and so on until when the last cross bar of the section has passed the guide bar
the beads are by the cut off bar blocked back on the needles until the cut off
bar is lifted by the second cross bar of the next section thus forming between
the last cross bar of one section and the first cross bar of the next section the
clear spaces on the threads where they have to be cut for bunching up the
beads. Immediately in front of the said guide bar and cut off bar we prefer
to provide an indiarubber or other roller under which the needles are situated
and which roller is immediately above the tops of the cross bars of the sections
the object of this roller being to assist in keeping the needles properly in the
vertical slits or notches of the cross bars of the sections. In combination with
the guide bar and cut off bar above described we employ a revolving brush at
a short distance higher up the needles so as to move the beads down the needles
and ensure the beads properly filling up the spaces between the cross bars of the
sections.

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 for threading glass and other beads
and consists firstly of improved means for threading the beads on to the needles ;
secondly of improved means for properly delivering the beads off the needles
(which are arranged at certain distances apart side by side) on to the threads or
wires so as to ensure the beads lying evenly between the upwardly projecting
notched cross bars of the short boards or sections in which the threads or wires lie
and by which the beads are moved along the threads or wires and divided for
bunching as described in the Specification of our Letters Patent No. 21192
of A.D. 1892.
This invention is illustrated by the accompanying drawings on which the same
letters of reference indicate the same or corresponding parts in all the figures.
Fig. 1 is a side elevation of a bead threading machine constructed according to
this invention; Fig. 2 is a plan of the same; Fig. 3 is a sectional side elevation of
the same; Fig. 4 is a cross sectional elevation of the same;
Fig. 4 shews the front end of one of the moving boards or sections;
Fig. 5 shews a part of the machine separately; Fig. 6 shews another part of the
same separately;
Fig. 7 shews the needle holder of the same separately with the needles in
position but the lower parts of the needles are broken away;
Figs. 8, 9, 10 and 11 illustrate that part of the said machine by which the
passage of the beads off the needles and on to the threads is regulated.
According to the first part of this invention (see Figs. 1, 2, 3 and 4) we provide
a stationary horizontal partial cylinder A formed with or fixed to the frame B of
the machine the ends of this cylinder are closed as by the covers a' a². Passing
longitudinally through the cylinder A there is a spindle c adapted to revolve in
bearings in the covers a' a' this spindle may and by preference does form the axis
of the cylinder. Mounted upon this spindle there is a circular brush C the bristles
cf which are by preference arranged in longitudinal rows as shewn. The upper
portion a of the cylinder is open and may be provided with a removable cover a*.
Into this open part as the beads are fed continuously down the inclined spout a
from the hopper or trough as; or the beads may be placed in the cylinder A by
hand or by other means so as to fill the cylinder A and the space between the
bristles of the brush C as shewn in Fig. 3. Dipping into the upper open part of
the cylinder A there are any convenient number of needles D (in our drawings we
have shewn twelve but there may be either more or less) arranged in a row side by
side the ends d¹ of these needles D which dip into the cylinder being by preference
hooked backwardly as shewn in Figs. 3 and 7 so as to meet the bristles of the
brush C when revolving as hereinafter described and the needles are mounted so as
to remain stationary for instance as described in the Specification of our Letters
Patent No. 19322 of A.D. 1891. When the spindle c¹ and brush C revolve in the
direction shewn by the arrow in Fig. 3 the beads are carried round with and by the
brush inside the cylinder and thus are threaded on to the needles D which dip
into the revolving beads. As the beads are threaded from the cylinder A the
supply is maintained by other beads sliding down the inclined spout a from the
hopper or trough a but the cylinder A never gets too full as the revolving heads
filling in the spaces between the bristles of the brush block up the spout a' and

page_text: prevent any more moving down until some of those which are revolving have been
threaded. The beads when threaded on the needles are moved along the same by
any convenient means such for instance as described' in the Specification of our
previous Letters Patent above referred to.
We will now describe the second part of this invention. E' is one of the
movable sections or boards made as described in the Specification of our prior
Letters Patent No. 21192 of A.D. 1892 with vertical notched cross bars e¹ eª e³ e¹ &c.
for moving the beads off the needles and on to and along the threads and for
forming the clear spaces for bunching the beads. As the said boards or sections
are moved successively under the eye end parts of the needles D from the back
of the machine, in the direction shewn by the arrow on the board, it is important
that only sufficient beads should be allowed to pass down on to the part of the
needles Ď and threads g between the cross bars as will just fill in the spaces between
the cross bars otherwise the beads will be liable to ride upon the tops of the cross
bars and the tension on the threads will be increased so that the threads may
break or the needles be broken or pulled out of the machine.
In order to regulate the passage of the beads down the needles as aforesaid and
also form the clear spaces on the threads for bunching the beads we proceed as
follows: We employ a guide bar F (shewn separately by Fig. 5) for the eye and
portions of the needles, this guide bar being provided with side arms fjointed
at ff to the frame B of the machine so that the guide bar F will be in a horizontal
position immediately above or so as to rest in the tops of the cross bars e¹¹³ee etc.
on the movable boards or sections. The adjustable side screws b₁62 fixed in the
frame B of the machine and with which the side projections on the arm F come
into contact form stops to prevent the guide bar F turning down too far. The
upper surface of the guide bar F is made with grooves in this case twelve in
number corresponding with the needles D and with the notches or slots €10 in the
cross bars e e e etc. of the moving sections E' these grooves in the guide bar F
being large enough to allow of the beads passing down the needles easily.
Immediately in front of the guide bar F and above the tops of the cross bars e¹ e²e³
we provide a cut off bar H (shewn separately by Fig. 6) which by side arms h
is jointed at h³ to the swinging frame J' Js (hereinafter described) of the machine
so as to be capable of moving up and down. This cut off bar H is by preference
slit at intervals h between the needles so as to form a number of thin spring
tongues one for each needle, the lower ends of these tongues being slightly bent
inwardly as shewn so as the better to engage with the beads as hereinafter
described. When this cut off bar H. is in its lowest position, see Figs. 3, 8, 9
and 11, its bottom edge rests on the needles between the beads so as to prevent the
beads passing along the needles out of the grooves ✓ of the guide bar F but when
this cut off bar H is lifted as shewn in Fig. 10 then the beads are free to pass along
the needles ont of the grooves f" of the guide bar F. This cut off bar H has an
inclined portion h underneath it at each side which is acted upon by the parts e¹³
of the cross bars el ee³ etc. so that the cut off bar H is lifted by every cross bar
passing under it except the first cross bar of each section which is cut away at ell
(see Fig. 4) so as not to lift the cut off bar H. Immediately in front of the cut
off bar H and guide bar F we provide a revolving roller or wiper I made with
flexible projecting vanes preferably of leather which act upon those beads which
have passed the cut off bar H and move them down the needles close together so as
to properly fill up the spaces between the cross bars e e e etc. of the moving
sections E. A further object of this revolving roller or wiper I is to keep the
needles down properly in the vertical slits or notches eo of the cross bars e¹³ ³ etc.
of the moving sections E. To enable the needles D to be readily removed from
or replaced in the machine this revolving roller or wiper I is mounted in bearings
in the sides of the swinging frame J J which at is hinged to the frame B of the
machine. The revolving brush K which acts upon the beads on the needles above
the cut off bar H and guide bar F is also carried by this swinging frame so that
when the frame is turned upwardly about its jointed end j¹ as indicated by the

page_text: dotted lines in Fig. 3 the needles can readily be removed. The roller or wiper I
and the brush K receive rotary motion in the direction indicated by the arrows in-
Fig. 1 by a band such as from any convenient source as from the spindle c' which
is the first driving shaft of the machine and is caused to revolve by a band driven.
on to the pulley c². The cut off bar H is also by preference jointed to this.
swinging frame J¹ J at h³ h' so as to be lifted with it when the needles have to be
removed.
The mechanisin above described operates as follows:-When there is no moving
section such as E' being pushed under the needles from the back of the machine in
the direction indicated by the arrow in Fig. 3, so as to lift the cut off bar H, the
latter, being in its lowest position as shewn by Figs. 3, 8, 9 and 11, blocks the
beads on the needles D' a short distance above their eyes. When the section or
board E is moved along in the direction of the arrow as aforesaid the first cross
bar e' thereon fails to lift the cut off bar H as this cross bar is cut away at el so as
not to act upon the inclines h of the cut off bhar H but when this first cross bar e¹
is moved for a short distance in front of the guide bar F the cut off bar H is by-
the next cross bare of the section E' raised and the beads immediately pass down
the needles until they come in contact with the first cross bar el and they continue
to thus move down the needles until the second cross bar e arrives underneath the
front side of the guide bar F as shewn in Fig. 3 when the cut off bar H falls and
prevents any more beads passing, thus having allowed just sufficient beads to pass
the guide bar F as will fill the space between the two cross bars el e' of the section..
Then as the section E' continues to be moved forward see Figs. 8 and 9 the third
cross bar comes into contact with the incline and the cut off bar H is again
lifted see Fig. 10 and when another measured quantity of beads have passed the
guide bar F the cut off bar H again falls and blocks the beads on the needles see
Fig. 11 and so on until when the last cross bar of the section has passed the guide
bar F the beads are by the cut off bar H blocked back on the needles until the cut
off bar H is lifted by the second cross bar e² of the next section thus forming
between the last cross bar of one section E¹ and the first cross bar e¹ of the next
section the clear spaces on the threads g where they have to be cut for bunching up.
the beads.
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 a bead threading machine the employment of a stationary partial cylinder
mounted horizontally and having its ends closed and upper side open so as to.
contain the beads, the said cylinder having a revolving brush mounted in it
horizontally by which the beads are revolved in the cylinder so that they will
be threaded on to the needles when dipping therein, substantially as hereinbefore
set forth.
2. In a bead threading machine, the employment of a stationary partial cylinder
mounted horizontally and having its ends closed and upper side open so as to
contain the beads, said cylinder having a revolving brush mounted in it horizontally
by which the beads are revolved in the cylinder so that they will be threaded on to
the needles dipping therein, said cylinder communicating by an inclined passage
with a hopper or receptacle containing the supply of beads to be threaded and froin
which the beads pass down the passage into the cylinder to maintain a constant
supply to the needles, substantially as herein before set forth.
3. In a bead threading machine and in combination with the horizontal partial
cylinder containing the brush for revolving the beads as denoted under Claims
and 2 the employment of the needles D arranged side by side around or partly
around revolving guide rollers and dipping into the upper open side of the cylinder
so that as the brush and beads revolve the latter will be threaded on to the needles
and pass down and along the same on to the cottons or wires, as hereinbefore set.
