PROVISIONAL SPECIFICATION.
Improvements in Machinery for Manufacturing Wire Netting.
I, EDWARD SAMUEL BOND of the Crown Engine Works Lower Hurst Street
Birmingham in the County of Warwick Engineer and Machinist do hereby declare
the nature of my said invention to be as follows :—
My invention has for its object improvements in machinery for manufacturing
wire netting and relates more particularly to the means for operating the racks and
pinions for twisting the wire being a further improvement on my previous Patent
No. 1087 A.D. 1889 and by which I operate the said racks in a much more direct
manner which is of great importance when manufacturing wire netting of strong
gauge as the vibration is considerably reduced another portion of my invention has
for its object the reduction of vibration and noise caused by the necessary sudden
stop and reversing of the plates in their travel.
or
In carrying my invention into effect the disc for operating the racks backwards
and forwards is mounted upon suitable brackets upon and parallel with the one
end of the machine and this disc is operated from the main shaft by a pinion
pinions upon the disc and so as to form a crank a roller is mounted which roller
works in a vertical slot or groove in a sliding bracket so that as the disc revolves
the bracket is moved horizontally backwards and forwards upon this sliding bracket
a toothed rack is formed which toothed rack engages with a toothed pinion upon
a vertical shaft which has a toothed wheel or segment both at the bottom engaging
with teeth formed on the outside of the main racks of the machine a slot being
formed in the side of the plates to allow of the toothed wheel engaging with the
teeth on the rack. The travel of the racks is adjusted by means of the adjustable
roller on the disc the throw of which is increased or decreased as may be desired.
The operation is then as follows:-
The revolving of the disc operates the toothed rack on the bracket which in turn
actuates the pinion upon the vertical shaft thus turning the toothed wheels or
segments backwards and forwards and as these engage in teeth formed in the racks
the racks receive a similar backward and forward movement from the main shaft
in a most direct manner.
The other portion of my invention refers to the mode of stopping and reversing
the travel of the plates without vibration & this I effect by forming a cylinder or
other cavity at each end of one of each pair of plates and a piston or projection at
the end of the other plates the said piston or projection on the one plate working
in the cylinder or cavity on the other plate with an intermediate cushion of air gas
water or steam thereby forming a stop between the two plates which considerably
reduces the vibration & noise. A. small relief aperture may be formed from the
cylinder or cavity to relieve the extreme pressure.

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 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 improvements in machinery for manufacturing
wire netting, and relates more particularly to the means for operating the racks and
pinions for twisting the wire being a further improvement on my previous Patent
No. 1087 A.D. 1889, and by which I operate the said racks in a much more direct
manner which is of great importance when manufacturing wire netting of strong
gauge as the vibration is considerally reduced; another portion of my invention
has for its object the reduction of vibration and noise caused by the necessary
sudden stop and reversing of the plates or beams in their travel.
In carrying my invention into effect the discs for operating the racks backwards
or forwards is mounted upon suitable brackets upon and parallel with the one end
of the machine and this disc is operated from the main shaft by a pinion or spur
wheel. Upon the disc and so as to form a crank a roller is mounted which roller
works in a vertical slot or groove in a sliding bracket so that as the disc revolves
the bracket is moved horizontally backwards and forwards. Upon this bracket
another rack is formed: which toothed rack engages with a toothed spur upon a
vertical shaft which has a toothed wheel or segment both at the top and bottom
engaging with teeth formed on the outside of the main racks of the machine a slot
being formed in the side of the stretchers and plates or bearings to allow of the
toothed wheel engaging with the teeth in the rack. The travel of the racks is
adjusted by means of the adjustable roller on the dise the throw of which is
increased or decreased as may be desired. The operation is then as follows:-
The revolving of the disc operates the toothed rack on the bracket which in
turn operates the spur upon the vertical shaft these turning the toothed wheels or
segments backwards and forwards and as these engage with teeth formed in the
racks the racks receive a similar backward and forward movement from the main
shaft in a most direct manner for turning the pinions for twisting the wire.
The other portion of my invention refers to the mode of stopping and reversing
the travel of the plates without vibration and this 1 effect by forming a cylinder
or other cavity at each end of one of each pair of plates or beams and a piston or
projection at each end of the other plate the said pistons or projections on the one
plate working in the cylinders or cavities on the other plate with an intermediate
cushion of air, gas, water or steam thereby forming a stop between the two plates
which considerably reduces the vibration and noise and stops the plates dead in the
position for the turning of the pinions which thus locks them together. A small
relief aperture may be provided from the cylinder or cavity to relieve the extreme
pressure of the pneumatic or other cushion.
In order that my invention may be clearly understood and more easily carried
into practice have appended hereunto a double sized sheet of drawings upon
which I have illustrated the nature of my said improvements.
Figure 1, is a perspective view of one end of my machine shewing the mode of
operating the racks.
Figure 2, is a perspective view of the plate C shewing the arrangement for
saving the concussion or shock caused by the reversing of the plates.

page_text: Figure 3, is a section through Figure 2 on the line 1-2.
Figure 4 is a similar section to Figure 3 but showing a modification.
The operation of the plates C and C and the general operation of the machine
is similar to that shewn in my former Patent before referred to. The first part of
my, present improvement consists of the operation of the racks D of which I now
use but one in cach pair of plates C for the operation of the pinions E. The
reciprocating motion of these racks is effected by means of the toothed disc A
which is mounted on the frame Y at one end of the machine this disc A being.
operated from the main driving shaft by the spur a'. The roller or stud a² is
mounted on the disc A and works in the vertical slot or groove b formed in the
sliding crosshead or bracket B so that as the disc A revolves, the bracket is moved
backwards & forwards in a horizontal direction in the slides y¹, y², and y³ which
are formed on the frame Y. Upon this bracket B the toothed rack 62 is formed
which rack engages with and operates the spur F upon the vertical shaft 1
which also has upon it at the top and bottom the toothed wheels or segments H
and H which engage with the teeth d formed on the outside of the main racks D
of the machine and thus operating them backwards and forwards. Apertures t¹ & c
are formed in the stretchers T and plates C to allow the toothed wheels H and H¹
to engage with the racks D for the operation of the pinions E for twisting the
wire. The stud or roller a² is adjustably mounted in a radial slide formed on the
disc A. so that the travel of the cross head or bracket B may be adjusted to give
the desired travel to the racks D.
The other portion of my invention which relates to the stopping of the plates C
which both have a reciprocating movement and a piston M at each end of the
fellow plate as shewn by Figures 2 &.3 so that the air in the cylinder forms an
efficient cushion and saves the conçussion and vibration which usually occurs when
the plates are stopped before taking the reverse movement and a small valve or air
hole is provided for the slow escape of air. In the case of plates of medium
weight I find it desirable to form or fix a plate N upon each of the plates so that as
they come together the air between the two faces n' of the plates forms a cushion
sufficient to prevent any material shock or concussion and the face n' of the plates
may be increased in size to suit the weight of the plates. The surface of one plate
may also be made concave or convex as may be desired. In these arrangements
both the piston and cylinder and the two plates form a perfect, certain, and dead
stop to the plates or beams c & c which is of great importance as previously the
plates were liable not to come exactly into the same relative position at each stroke
which prevented the pinions E being turned by the rack; damage to the machine
being the result. I do not confine myself to the position shewn for the surface
plates N or cylinder M and piston K as they may be placed at any convenient
position with regard to the plates C & C and may be attached to existing
machines.
