PROVISIONAL SPECIFICATION.
A New or Improved Automatic Stop Motion for Wire Netting and
other Wire Working Machines.
I, EDWARD SAMUEL BOND of Crown Machine Works, Lower Hurst Street
East, Birmingham, in the County of Warwick, Engineer & Machinist, do hereby
declare the nature of my said invention to be as follows :-
My invention has for its object a new or improved automatic stop motion for
wire netting and other wire working machines by which a breaking or running out
of any one of the strands is immediately detected however fast the machine may be
running while the machine is automatically and instantly stopped by the detecting
arrangement and any gap in the mesh is thus prevented. In machines of this class
it has hitherto been necessary to run them at a moderate speed to enable the
attendant to detect any breakage of the wire but with the addition of the following
automatic detector stop motion a machine may be run up to its greatest capacity
without attention and without fear of the machine continuing to work with any one
of the strands broken. I also apply a device to such machines so that upon a
certain length of netting having been made the machine is automatically stopped
ready for the length to be severed from the machine prior to the commencement of
another length.
I will proceed to describe my invention applied to an ordinary wire netting
machine in which the wire is twisted and the mesh formed by the operation of two
rows of revolving pinions mounted one row above the other in reciprocating plates
one strand of each mesh of the wire being drawn from a coil within an inter-
mediate vertical tube the other strand being drawn from bobbins at the rear of the
machine the finished mesh being drawn up vertically by an horizontal roller.
In carrying my invention into effect a rod or shaft is mounted in brackets
attached to any convenient part of the framework of the machine the rod being so
arranged as to run the whole length of the machine being preferably situated at
the rear and upon a level with the point at which the mesh is formed by the
twisting of the wire by the pinions. Upon this rod or roller is mounted a series of
levers to turn one lever being provided for each double strand of mesh and each of
these levers are provided at the front end with a tail piece which is weighted and
at the reverse end or upon the other side of the pivot or bearing of the lever with
a nose piece. At the rear of the rod and also running the whole length of the
machine a table is pivoted at each end so that one side of the table runs along and
above the whole of the nose pieces of the levers and to one of the pivots of this
table a rod is attached to form a lever which is operated by the turning of the
table and in turn operates the stopping mechanism of the machine as will be after-
wards described.
The action of the above arrangement is then as follows:-Each of the pivotted
levers are placed with their tail pieces in a raised position upon the first twisted
strand of the mesh shove the top pinions in which position they rise with the
twisted strand until raised sufficiently high for the end of the lever to clear it
after which they fall upon the next twisted strand which is then being formed and
is rising underneath. So long as the strands of wire remain intact this action takes
place without the nose end of the lever in any way actuating the pivoted table but
Immediately upon running out or breakage takes place in either of the strands the
ail of the lever falls through the gap thus made sufficiently for the nose piece on
the other end to tilt up the one side of the pivoted table and thus actuate the lever
which is connected to its pivot.
As the strands from the bobbins run horizontally from the rear it is necessary to

page_text: provide an arrangement whereby the breaking or running out of the strands at
that point should stop the machine and to effect this a number of crank levers are
pivotted upon a supporting plate through which the wires pass. One end of each
crank lever forms a vertical tail piece the other end being horizontal and weighted
so as to press the vertical tail against the horizontal wire. Above the crank lever
n. rocking plate is mounted and balanced by suspending weights and from each
crank lever a stud or nose piece rises vertically and enters a slot formed in the
rocking plate each slot being provided with sufficient clearance in the one direction
so that upon the breaking of any one strand the tail piece allows the weight on the
crank lever to fall and causes the nose piece or stud to rock the plate in the other
direction sufficiently to operate a rod or lever which is connected with the
rocking plate and with the stopping mechanism of the machine as afterwards
described.
For operating the stopping mechanism of the machine by means of the movement
of the pivotted table or rocking plate a crank or eccentric is formed upon the main
shaft of the machine and to this crank or eccentric a ram is attached so as to have
a continual reciprocating sliding movement and on a line and level with this ram a
sliding buffer is attached to one end of a crank lever the other end of which is
attached to a rod on the belt shifting fork pivotted to the ram and between it and
the buffer a tumbler or dropper is mounted the normal position of its point being
clear of the buffer during the reciprocating motion of the ram but this tumbler
being connected by crank lever & rods with the pivotted table or rocking plate
the movement of either of these as before described brings the tumbler into a line
with the buffer and the first thrust of the ram operates the buffer and through it
throws off the band from the fast to loose pulley whereby the machine is instantly
stopped.
One mode of automatically stopping the machine at any required time consists
of a revolving disc or dial which is geared down. in speed from the main shaft &
upon this disc a stud is mounted so that its position may be adjustable and so that
it may in its movement operate a lever which actuates the rocking plate or
pivotted table connected with the aforesaid dropper or tumbler thus bringing it
into line with the ram by the thrust of which the machine is instantly stopped as
before described.
It will be obvious that my improvement can be equally applied to any kind of
stopping mechanism whether friction, clutch, or otherwise and that the details of
the arrangement may be varied to suit different machines.

COMPLETE SPECIFICATION.
A New or Improved Automatic Stop Motion for Wire Netting and
other Wire Working Machines.
I, EDWARD SAMUEL BOND, of Crown Machine Works, Lower Hurst Street
Enst, Birmingham, in the County of Warwick, Engineer and Machinist, do hereby
declare the nature of my said invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:
My invention has for its object a new or improved automatic stop motion for
wire netting and other wire working machines by which a breaking or running out
of any one of the strands is immediately detected however fast the machine may be
running while the machine is automatically and instantly stopped by the detecting
arrangement and any gap in the mesh is thus prevented. In machines of this class
it has hitherto been necessary to run them at a moderate speed to enable the
attendant to detect any breakage of the wire but with the addition of the following

page_text: automatic detector stop motion a machine may be run up to its greatest capacity
without attention and without fear of the machine continuing to work with any one
of the strands broken. I also apply a device to such machines so that upon a
certain length of netting having been made the machine is automatically stopped
ready for the length to be severed from the machine prior to the commencement of
another length.
I will proceed to describe my invention applied to an ordinary wire netting
machine in which the wire is twisted and the mesh formed by the operation of two
rows of revolving pinions mounted one row above the other in reciprocating plates
one strand of each mesh of the wire being drawn from a coil within an intermediate
vertical tube the other strand being drawn from bobbins at the rear of the machine
the finished mesh being drawn up vertically by an horizontal roller.
In carrying my invention into effect a rod or shaft is mounted in brackets
attached to any convenient part of the framework of the machine the rod being so
arranged as to run the whole length of the machine being preferably situated at
the rear and upon a level with the point at which the mesh is formed by the
twisting of the wire by the pinions. Upon this rod or roller a series of levers are
mounted to turn one lever being provided for each double strand of mesh and each
of these levers are provided at the front end with a tail piece which is weighted
and at the reverse end upon the other side of the pivot or bearing of the lever with
a nose piece. At the rear of the rod and also running the whole length of the
machine a table is pivotted at each end so that one side of the table runs along and
above the whole of the nose pieces of the levers and to one of the pivots of this
table a rod is attached to form a lever which is operated by the turning of the
table and in turn operates the stopping mechanism of the machine as will be after-
wards described.
The action of the above arrangement is then as follows:-Each of the pivotted
levers are placed with their tail pieces in a raised position upon the first twisted
strand of the mesh above the top pinions in which position they rise with the
twisted strand until raised sufficiently high for the end of the lever to clear it after
which they fall upon the next twisted strand which is then being formed and rising
underneath. So long as the strands of wire remain intact this action takes place
without the nose end of the lever in any way actuating the pivotted table but
immediately a breakage or running out takes place in either of the strands the tail
of the lever falls through the gap thus made sufficiently for the nose piece on the
other end to tilt up the one side of the pivotted table and thus actuate the lever
which is connected to its pivot.
As the strands from the bobbins run horizontally from the rear it is necessary to
provide an arrangement whereby the breaking or running out of the strands at that
point should stop the machine and to effect this a number of crank levers are
pivotted upon a supporting plate through which the wires pass. One end of each
crank lever forms a vertical tail piece the other end being horizontal and weighted
so as to press the vertical tail against the horizontal wire. Above the crank lover
a rocking plate is mounted and balanced by suspending weights and from each
crank lever a stud or nose piece rises vertically and enters a slot formed in the
rocking plate each slot being provided with sufficient clearance in the one direction
so that upon the breaking of any one strand the tail piece allows the weight on
the crank lever to fall and causes the nose piece or stud to rock the plate in the
other direction sufficiently to operate a rod or lever which is connected with the
rocking plate and with the stopping mechanism of the machine as afterwards
described.
For operating the stopping mechanism of the machine by means of the move-
ment of the pivotted table or rocking plate a crank or eccentric is formed upon
the main shaft of the machine and to this crank or eccentric a ram is attached
so as to have a continual reciprocating sliding movement and on a line and level
with the ram a sliding buffer is attached to one end of a crank lever the other
end of which is attached to a rod on the belt shifting fork; pivotted to the

page_text: ram and between it and the buffer a tumbler or dropper is mounted the normal
position of its point being clear of the Buffer during the reciprocating motion
of the ram but this tumbler being connected by crank lever and rods with
the pivotted table or rocking plate the movement of either of these as before
described brings the tumblers into a line with the buffer and the first thrust of the
ram operates the buffer and through it throws off the band from the fast to loose
pulley whereby the machine is instantly stopped.
One mode of automatically stopping the machine at any required time consists
of a revolving disc or dial which is geared down in speed from the main shaft and
upon this disc a stud is mounted so that its position may be adjustable and so that
it may in its movement operate a lever which actuates the rocking plate or pivotted
table connected with the aforesaid dropper or tumbler thus bringing it into line
with the ram by the thrust of which the machine is instantly stopped as before
described.
It will be obvious that my improvement can be equally applied to any kind of
stopping mechanism whether friction clutch or otherwise and that the details of
the arrangement may be varied to suit different machines.
In order that my invention may be clearly understood and more easily carried
into practice I have appended hereunto three double sized sheets of drawings upon
which I have fully illustrated the nature of my said improvements applied to a
similar wire netting machine to those described and illustrated in my previous
Patents No. 1087 A.D. 1889 and No. 15943 A.D. 1890 and from which its
application to other wire netting and wire working machines will be readily
understood.

motion applied to the netting.

wires running from the bobbins at the bottom of the machine.
Figure 6, is a plan of Figure 5.
Figure 7, is an elevation of the revolving disc arrangement for automatically

Figure 8, is a plan of Figure 7.
I will proceed to describe my invention applied to an ordinary wire netting
machine in which the wire A is twisted and the mesh formed by the operation of
two rows of pinions E which are revolved by the rack e and mounted one row
above the other in reciprocating plates C one strand of the wire being drawn from
a coil within the intermediate vertical tube H the other strand a being drawn
from bobbins at the rear of the machine the finished mesh A being drawn up
vertically by the horizontal roller K.
In carrying my invention into effect the rod or shaft D is mounted in the
brackets which are attached to any convenient part of the stationary part of the
machine being preferably situated at a level with the point at which the mesh A
is formed by the twisting of the wire by the pinions E. Upon this rod or shaft D
a series of levers or droppers M are mounted to turn, one dropper M being
provided for each of the meshes or half meshes E and each of the levers are
provided at the one end with the tail piece m' which is weighted at m³ and having
at the other end the nose piece m' upon the other side of the pivot or bearing of
the dropper. Running the whole length of the machine the table B is pivotted at
various points as at 6 and runs along and above the whole of the nose pieces m³
of the lever and to the pivot of this table the crank-6 is attached to form a lever
which is operated by the turning of the table B and which in turn operates the
stopping mechanism through the rod N as will be afterwards described.
The action of the above is then as follows:-Each of the pivotted droppers M

page_text: are placed with their tail pieces m¹ in an horizontal position upon the first twisted
strand of the mesh above the top of the top pinions E from which position they
rise with the twisted strand until raised sufficiently high for the end of the dropper
to clear it after which they fall upon the next meshes then being formed and rising
underneath. So long as the strands of wire remain intact the action takes place
without the nose end m of the lever or dropper M in any way actuating the
pivotted table B but immediately a running out or breakage takes place in either of
the strands the tail m' of the lever falls through the gap thus made and raises the
nose piece meufficiently to tilt up the one side of the pivotted table B and thereby
actuate the lever 3 and rod N. The droppers E may be modified in shape and
used in combination with mechanism other than that of the tilting table B.
As the strands a run horizontally from bobbins at the rear of the machine an
arrangement is provided whereby the breaking or running out of such strands at
that point should automatically stop the machine and to effect. this a number of
crank levers P are pivotted at pl upon the supporting plate R through which the
strands a pass, the apertures p being provided for this purpose one end of each
crank lever forms the vertical tail piece the other end p being horizontal and
weighted so 08 to press the vertical tail p³ against the horizontal wire a³.
Above these crank levers the rocking plate S is mounted and balanced by the
suspending weights & which are hinged at and from each crank lever a stud or
nose piece prises vertically and enters a slot & formed in the rocking plate S each
slot being provided with sufficient clearance at so that upon any one of the
strands a becoming broken the tail piece p of that respective strand is thereby
released which allows the weight p to fall thus causing the nose piece or stud p
to rock the plate in the other direction sufficiently to operate the rod or lever T
which is hinged to the rocking plate at t and connected with the stopping
mechanism of the machine as before described.
For operating the stopping mechanism of the machine by means of the movement
of the pivotted table or rocking plate a crank or eccentric V is formed upon or
attached to any convenient part of the driving shaft of the machine and to this
crank or eccentric the ram o is attached which has a reciprocating motion and
slides in the bearing which is attached to any suitable part of the main frame
of the machine and in a line and level with this. ram the sliding buffer W is
mounted in the bearing w¹ and is connected with one end of the pivotted crank
lever to the other end of which is attached to the rod wupon which the belt
shifting fork is mounted and between the buffer W and ram v¹ the tumbler or
dropper is mounted the normal position when the machine is properly at work
being as shewn by dotted lines in Figure 3 with its point clear of the buffer
during its reciprocating motion but this tumbler of being connected by the crank
lever n' and rod N with the lever 6' upon the pivotted table and with the rod T
upon the rocking table the movement of the table B or S in either case brings the
tumbler into a line with the buffer W by which the first thrust of the ram
operates the buffer and through it throws off the band from the fast to loose pulley
whereby the machine is instantly stopped.
For automatically stopping the machine after any required length of the netting
has been made I use in conjunction with the droppers M and pivotted table Ba
revolving disc or dial X the bearing of which is mounted upon any convenient part
of the framework of the machine and this diso or dial X is geared down in speed
from the roller K which draws up the netting by a worm gearing with the teeth t
and has upon its face the stud which is made to be adjustable in the groove z²
in its position so that it may as it rotates catch against the pivotted lever y² and
withdraw the lever Y from under the extra dropper me which actuates the pivotted
table B and in turn operates the pivotted dropper or tumbler as before described
and thus the machine is stopped.
It will be obvious that my improvements can be equally applied to any class of
machine stopping attachment whether friction clutch or otherwise and further that

page_text: the details and arrangement of the parts may be varied to suit the great variety of
machines to which the improvement is applicable.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what 'I
claim is :-
1st. A new or improved automatic detector stop motion for wire netting and
other wire working machines substantially as and for the purpose herein set forth
