Improvements in Machinery for Coiling Wire for. Use in Wire
Netting Machines.
We EDWARD SAMUEL BOND of the Crown Engine and Machine Works Lower
Hurst Street East, Birmingham in the County of Warwick, Engineer and Machinist
and SAMUEL WILLIAM JOHNSON of No. 55, Upper Sutton Street, Aston near
Birmingham aforesaid do hereby declare the nature of our said invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement :-
Our invention has for its object improvements in machinery for coiling wire for
use in wire netting machines and has particular reference to the machine described
in our former patent dated 29th of December 1884, and numbered 16977 the
present improvements consisting in the reversal for a few revolutions of the winding
spindle or spindles after the first coil or layer of wire is wound thereon so that this
first coil or layer is enlarged in its diameter sufficiently to make it loose upon the
spindle before the second or succeeding layers are wound upon the first coil thus
permitting the easy withdrawal of the spindle after the winding is completed by which
means we avoid the necessity for the split collapsing casing or other device hitherto
used which wo accomplish by a modification of gearing hereafter to be explained.
Our improvements consists also of a device for supporting the spindles at the
particular point where the strain of the coiling of the wire has a tendency to bend
them and by these means we are enabled by the use of a smaller spindle to coil
the wire much smaller and at the same time extend the length of the spindle for
coiling purposes to a much greater extent than hitherto.
We also obviate the necessity of the attendant going to the back of the machine
to adjust the stop which is provided for regulating the length of the coil required
and substitute a handle lever and ratchet whereby the same means may be attained
from the front of the machine in a more effective and easy manner. We also provide
adjustable stops upon the spindles whereby the end of the coil at whatever point is
Kept close up without chance of spreading during the reversal of the coil.
In order that our invention may be clearly understood and more easily carried
into practice we have appended hereunto two sheets of drawings upon which we
го

Figure 6 is an enlarged sectional elevation on the line 5. 6. through the shaft: K
and clutch Y.
Figure 7 is a side elevation of the stop lever H.
We will first proceed to describe our arrangement for reversing the direction
in which the spindles revolve and as in our previous specification A represents the
table of the machine having the standard B at the end for the supporting of the
ends of the main shaft C and main screw E both of which revolvo in suitable
bearings the standards also being made to carry the ends of the guide rods D. D. which
are securely fastened to them. The motion for revolving, the said spindles M. M
upon which the wire is wound is communicated from the driving shaft C by means of
the spur wheel G gearing into the change wheel G¹ which is attached to a similar
wheel G both being carried on the moveable stud G³ so as to be capable of being
changed for adjustment of speed. The said spur wheel G gears into the spur
wheel Z which runs loose upon the shaft K. and is provided on the. one side with
the cam Upon this same shaft Z the clutch Y is mounted to revolve with the
shaft by means of the keys y' and y Figure 6 sheet 2 which also allow lateral
movement of the said clutch. The face y³ of the clutch is provided with a cam
which is so formed as to engage in the cam z so that it will be readily seen that by
these means the shaft K which communicates with the spindles by means of the
spurs K and K can be readily engaged or disengaged from the propelling power at
this point by means of the handle S which is provided with the studs working in
the groove y' in the clutch Y. On the other face y of the clutch a similar cam is
formed which is made to engage in a similar cam a formed on the side of the
spur X which is also made to run loose upon the shaft K the end of the said
shaft K being supported by the bracket A which is secured to the bed A. The
spur wheel N which is formed in combination with the loose pulley F1 gears into the
spur X and as the transmission from the shaft C to the shaft K is in this case direct
instead of having the intermediate spur G' as in the other case it will be understood
that the engaging of the face y of the clutch with the face a on the wheel X will
revolve the shaft K the reverse way; the action of reversal being as follows:-As
soon as one coil of wire is formed the required distance along the spindle M during
which period the shaft K receives its motion by the clutch Y being made to engage
with the spur wheel Z the driving band may be transmitted to the loose pulley Fi
and the clutch Y is made to engage with the spur wheel X which reverses the motion
of the shaft K and spindles M which reversal increases the diameter of the coil of wire
sufficiently to allow of it being readily removed after the desired number of coils have
been wound round the first as described in my previous Specification. This process
of increasing the diameter of the coil somewhat reduces the length and we therefore
provide the sliding collars T for the purpose of sliding down to the position where
the, coil finishes where they are secured, by means of the thumb screws thereby
preventing the coil from again expanding on the, reversal of the machine but such
sliding collars are of distinct advantage in any case, for fixing against the extreme
end of the spring.
As the strain of the wire U has a tendency to bend the spindles M especially in, the
case where long ones of small diameter are used we support them in.the.direction of
the strain by the rollers pl and p² which are attached to the small piston, working
in the cylinder p₁ which is attached to the travelling carriage P. This allows of the

page_text: piston being pressed back as the coils increase in number the end of the said piston
finishing in the cylinder against the spring p which is of sufficient strength to
support the spindles but we do not confine ourselves to the exact details as we may
place the spring p' outside between the support and the carriage.
For the purpose of adjusting the length of the coils of wire to be wound we mount
the springs A described in our former Patent No. 16977 A.D. 1884 opposite each
other upon a carriage 17 Figures 8 & 9 so as to travel along the reversing_bar h.
This carriage is carried along by the projecting piece upon the carriage P until
the said carriage h' is stopped by the stop J at which point the projecting piece
passes between the spring and slot and reverses the motion as described in the previous
specification.
The stop J' is attached to the lever H which is pivotted by means of a suitable
bracket J to the bed A of the machine and engages at the front in the toothed
ratchet J which is also secured to the bed of the machine sufficient play being
allowed at the pivot J for the lever to be raised over the teeth by means of the
handle J which would be operated by the attendant thereby enabling the motion of
the carriage P to be reversed at any point by which means any desired length of coil
may be wound upon one machine without the necessity of the attendant passing to
the back of the machine to alter the adjustment.
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;
First: The improvements in the machinery for coiling wire for use in wire
netting machines by which the spindle or spindles are reversed to loosen the
foundation coil substantially as and for the purpose herein set forth.

nitting wheel N for the purpose of reversing the spindles M substantially as herein
set forth and shewn upon the drawings.
