PROVISIONAL SPECIFICATION.
Improved Machine for Weaving Rectangular Meshed Netting.
We, HENRY ARTHUR RENDALL, of the Firm of Rendall and Coombs, Flax and
Hemp Spinners and Manufacturers, and WILLIAM GEORGE ACKERMAN, of 56,
East Street, Jeweller, both of Bridport, in the County of Dorset, do hereby declare
the nature of this invention to be as follows:-
Our invention relates to an improved machine for weaving netting, with rect-
angular meshes and knots similar to those made on the diamond mesh machines,
and commonly known as fishermen's knots."
"
The weaving of nets with diagonal meshes by machinery is well known, but
so far as we are aware no practicable apparatus has been devised for producing
netting with square or rectangular meshes in as satisfactory a manner as the
same can be done by hand. By means of our invention we attain this result
and produce a square or rectangular mesh net, of quality equal to hand made,
by machinery, with great consequent economy of time and labour; moreover,
we can make one or more widths of net at the same time on one machine, and
each piece will have perfect selvedges. Further, we may make practically any
sized mesh, and we may use almost any textile or filiform material for the
purpose.
The warp for the netting may be supplied from a beam or from spools mounted
on a creel and the tension of the thread obtained by any suitable tension
mechanism. The warp threads are passed through an arrangement for dealing
with the slack during the process of making the knot. From here they pass
through separate warp guides and are eventually taken through the machine
to the receiving drum in the form of net.
The improved netting machine has the frame ends and like constructional
details similar to those of the netting machines commonly employed.
The special mechanism required for the rectangular netting consists essentially
of the following::
1. A set of warn guides placed at the back of the machine.

page_text: made fast to the receiver drum. Supposing the guides to be to the left of the
slip hooks they shog to the right carrying the warp threads on to the slip hooks,
then advance to the front of the knot pins, then shog to the left carrying the
warp threads on to the knot pins and withdraw returning to the left of and
somewhat above the slip hooks. The depressors now descend to the left of the
warp guides and rather in front of them, shog to the right carrying the warp
guide threads above and to the centre of the loops formed by the slip hooks and
knot pins, then descend again carrying the warp guide thread with them and
making a triangle large enough for the shuttle to pass through. Then the shuttle
is drawn across, carrying a weft thread on to the tumblers, and behind the
knot pins; the slur cock attached to the shuttle carriage forces back the
tumblers to the distance required for the intended mesh, then the depressors rise
and regain their original position. The slip hooks now advance towards the
knot pins, the tension mechanism in connection with the spools taking up the
slack. The slip hooks are carried at this time somewhat beyond the knot pins;
this movement strips the slip hooks and the knot pin is momentarily encircled by
the reduced loop, but hardly is thus effected when the knot pins disengage them-
selves both from the warp and weft threads; the latter of which are now held
in the loop or loose knot produced by the action of the slip hooks and knot
pins described above. These loose knots are forced forward against or nearly
against the tumblers and tightened by the brushes. Then the mesh governor
rises and pins (arranged on a bar beneath it and slightly on one side of the
tumblers) advance back and over the tumblers. Then the mesh governor sinks,
forcing back the tumblers which throw off their threads on to the pins just
referred to, the receiver drum is revolved at the same time sufficiently to take
up the newly formed mesh and the cycle is complete.
In the foregoing we have set forth the best method of carrying our invention
into effect at present known to us, but we do not limit ourselves to the precise details
herein set forth, it being evident that modifications in various details and com-
binations of parts may be introduced into the apparatus, and differences of
working arranged to meet differing requirements be provided for without exceed-
ing the scope of our invention.

In these drawings, 1 is the framework, part of which is shewn broken away in
Figure 1 for the clearness of the drawing; 2 is the main shaft, one revolution
of which completes one row of meshes; 3 is the guide arm shaft; 4 is the
depressor shaft; 5 is the slip hook shaft; 6 is the tension arm shaft. The
guides 7 have holes 8 through which pass the warp threads 9. Said guides 7 are
mounted upon a bar 10 which is arranged to slide longitudinally from left to
right in the ends 11 of the guide arms 12. The said guide arms 12 are keyed
upon the shaft 3 which runs the full length of the machine and is held in
bearings 14 at each end. The shaft 3 has also keyed upon it two rocking
levers 15 and 16, the first actuated by cam 17, and the latter by cam 18. both
cams 17 and 18 being keyed upon the shaft 2. The cam 17 actuates the arm 15
to move the guides backwards, and the cam 18 to operate the arm 16 to bring
the guides forward again, or a single grooved cam would serve the double
purpose (Figure 20). In order to obtain the left to right or "shogging" move-
ment of the bar 10 carrying the guides 7, two projections 19 and 20 are provided
upon the left hand end of the guide bar 10. The projecting stud 20 is arranged
to be caught by the arm 21 mounted upon shaft 23, which has secured upon it
at one end the arm 26, projecting downwards, and having at its end an anti-
friction roller 27. The said roller 27 engages with a cam piece 28 upon the.
cam 18, and thus rocks the shaft 23. The bearings 24 and 25 carry the shaft 23.
The depressor shaft 4 has keyed upon it four arms 30, 31, 32, 33, which support
the shuttle guide and depressor bar 35. The arm 30 is connected to the shuttle
guide 34, and the arms 31 and 32 are connected to the shuttle guide and
depressor bar 35, and the arm 33 is connected to the shuttle guide 36. The
shuttle guide bar 35 has the guides 37 spaced apart so as to allow the parts of
the warp forming the loop to pass up between them during the passage of the
shuttle through the shed. In order to obtain the necessary movement of the
arms 30, 31, 32, 33, the arm 30 is prolonged further outward as at 38, and has
attached to it a rod 39, which is in turn connected to a lever 40 (Figure 21 and
21). The said guide bars 35 and ends 34 and 36 are to all intents and purposes
one piece except that they are cut away at the points 500 and 501 so as to allow
the arms 46 and 47 carrying the slip hook bar 48 to pass between in the forward
movement of the said slip hook bar. One end of the lever 40 is pivoted to
the frame 1 of the machine at 42, and near the other end 43 is placed an anti-

page_text: friction roller 44, running upon a cam 45, keyed upon the shaft 2. This cam
is of such a shape that during the passage of the shuttle through the shed the
depressors 49 are down and at rest and during the forward and backward movement
of the guides 7 the depressors are up and at rest. The depressor shaft 4 is given
a certain amount of lateral play in the bearings in order to allow of the depressor 49
being shogged to the left and back again for the purpose hereinafter described.
In order to obtain this shogging movement the lepressor bar 35 has two pro-
jections 60 and 61, secured thereto, the projection 61 being struck by the arm 62
keyed to the vertical rod 63, provided with bearings 64 and 65. The lower end
of the said rod 63 terminates in a bent arm 66 with roller 67 which is actuated
by the projection 68, upon the side of the cam 54, and tends to shog the depressor
bar 35 to the left.
The depressor bar 35 is returned to its normal position by the striking of the
curved lever 60 against the roller 69 on the fixed arm 70, which is itself secured
to the frame of the machine. By this means as the depressor bar 35 rises, it
is shogged to the right into its normal position.
The slip hook shaft 5 has keyed upon it the arms 46 and 47 which support the
slip hooks bar 48. The bar 48 has fixed upon it the slip hooks 50. The neces-
sary movement is imparted to the shaft 5 by the lever connecting rod 52, the
rocking lever 53, and the cam 54. The rocking lever 53 has an arm 55 project-
ing from it midway between the ends 56 and the pivot 6. The said projection 55
has mounted upon it two rollers 58 and 59 which respectively engage with the
inside and outside of the cam surface of the cam 54. In order to shog the slip.
hooks 50 an arm 7.1 is keyed to the shaft 5. The roller 72 shogs the slip hooks 50
to the left when coming forward and a roller 73 shogs the slip books 50 to the
right when returning to commence a new loop.
:
The fixed knotting pins 74 are fixed upon a plate 76 which is secured by.
brackets to the frame of the machine. The movable knotting pins 75 are secured
to a plate 77 provided with pins 79 (Figure 4). A plate 78 with an upwardly
inclined slot 80 is arranged for the purpose of raising the plate 77 with the
pins 75 attached thereto, and the guides 81 are provided therefor. The plate 77
is actuated by the rod $2 secured to it, the bell crank lever 83, the rod 84 and.
the lever 85. A roller 86 secured to the wheel 87 operates the bent lever 85
to raise it, and a weight SS serves to return the lever to its original position.
Curved bars, known as brushes" 89 are secured to the bar 90, and are operated
at the completion of the knot by the projecting arm 92, having a pin 93 work-
ing in the groove 94 in a rocking arm 95, said arm rocking in bearings 96
secured to the frame of the machine. The end 97 of the lever 95 is joined to
the connecting rod 98. Said connecting rod 98 is connected to a lever 200 at
its end marked 99, and rocking in the bearing 101 secured to the main frame;
a weight 202 is provided to cause the return of the parts to their normal posi-
tions (Figure 2).
The end 203 strikes against the outside part 204 of the cam piece 68, and
lifts the lever 200 and parts connected thereto immediately after the receiving
pins have been withdrawn.
One
The receiving pins 205 (Figures 6 and 7) are secured to a plate 106 resting on
a plate 207. This plate 207 has a roller 108 extending its entire length, at its
under surface near the right hand side. The plate 207 has a slot 209 to allow
the pin 110 to pass up through it to the plate 106. The vertical pin 110 projects
from a bell crank lever 111 working on a pin secured to the plate 113.
end of the bell crank lever strikes against an angle piece 114 which is secured
to a sliding bar 215; (Figures 1 and 7). The sliding bar 215 is actuated by
the rod 216 attached to the end 217 of a rocking lever 218, working in bear-
ings 219. The other end 120 is actuated by the roller 121 secured to the cam 54..
The said plate 207 forming part of the mesh governor or apparatus for
regulating the size of the mesh, consists of a flat plate extending the entire

page_text: width of the machine. It is raised and lowered by rocking arms 122 secured
to a bar 123 running lengthways of the machine. The bar 123 is actuated by
an arm 124 (Fig. 1) provided with a roller 125 which strikes against a cam
piece 126 secured to the cam 54. The operative or right hand side of the mesh
governor plate 207 bears the roller 208 as stated above, whilst its left hand side
has a pair of arm pieces 127 connected to rocking levers 228, rocking on
pivots 229. The other end of each rocking lever is provided with a set screw 230
which bears against the bracket piece 231 which is secured to the plate 113 and
supports the said pivots 229; the bracket piece 231 also serves the purpose of
a bearing for the bar 123, Figure 6.
The tumbler 132 has a hooked end 133 to engage with the weft. The tumbler
is pivoted at 134 in bearings 135 secured to a bar 136, which is attached to the
main frame of the machine. The tumbler has also a projecting arm 239 provided
with a weight 140. Said tumbler is provided also with a projecting piece 341
for the purpose to be described.
THE SHUTTLE MECHANISM.
The shuttle carrier 137 slides in grooves 138 in the main portion 139 of the
carrier guide. The rack 140 runs lengthwise of the carrier guide and engages
with a carrier wheel 141 which also engages with another gear wheel 142 secured
to the shuttle carrier for the purpose hereinafter described. The shuttle carrier
has lugs 143 and 144 provided at either end, to which a chain 145 is connected.
The chain 145 passes over jockey pulleys 146, 147 and 148 which are mounted
in bearings secured to the main portion 139 of the shuttle carrier guide. The
chain 145 also passes around a sprocket wheel 149, said sprocket wheel being
secured to a rod 150, one end of which rod 150 is loosely held in the bearings 151,
the other end being allowed a slight lateral movement in a second bearing 152
(Figure 19). The rod 150 has secured to it at one end a small pinion wheel 153
engaging with the rack 154 on a wheel 155, said wheel being keyed to the shaft 2.
The slot in the bearing 152 is of such a width as to allow the pin 156 which
projects beyond the surface of the teeth 157 of the pinion wheel 153 to move
a distance equal to the width of the wheel 155. A trigger 158 is secured to the
wheel 155 by a pin 159, and has two projecting ends 160 and 161 which bear
against stops 162 and 163 formed by the inclined sides 164. Said plate 164
projects beyond the periphery of the wheel 155, and occupies the same plane as
that of the base of the teeth 154.
Assuming that the wheel 155 be rotated in the direction of the arrow 166, the
pinion wheel 153 will be rotated in the direction of the arrow 167, and will
continue rotating until it passes the last tooth 168 of the rack secured to the
wheel 155. As soon as it passes said teeth, the pinion wheel 153 will cease to
rotate and will strike against the points 165 of the trigger 158, passing along
one side of the trigger until it reaches the point 161, when it will then turn the
trigger 158 into the position indicated by the dotted line 169. It will then
travel along the side 170 of the rack wheel 155. The wheel 155 will continue
to rotate until the pinion wheel engages again with the rack 154 but this time
upon the opposite side. 170 of the rack wheel 155. The pinion 153 engaging with
the rack 154 will then be driven in the opposite direction. By this means a to
and fro motion is given to the shuttle carrier 137.
The shuttle carrier 137 has a plate 171 projecting in a sloping direction from
the shuttle carrier 137. said plate being provided with a bent rod 172 for the
purpose to be described. The rod 172 possesses means for partially rotating.it
by means of a screw 173, a block 174, and a projection 175. The said rod 172
is provided with bearings 176 secured to the plate 171. The plate 171 has also
a guide piece 177 attached thereto. The plate 171 is provided also with an
Secured to the shoot 178
extension piece 178 with sloping ends 179 and 180.
are two pins 181 working in two, slots 182 in a second plate 183 for the purpose
of operating the tumblers in the manner to be described.

The
It is provided with a top 185 and two curved pointed ends 186, and a lower
bar 187 which rests upon the wheels 142 of the shuttle carrier 137.
shuttle 184 is provided with a barrel end 188 and the other end 189 has a socket for
the spool spindle which is kept in its place by a hinged spring bar 190. One
end of the spool is provided with a centre pin 192 which enters the centre in
the axle 193. Said axle 193 has one end of a spring 194 attached thereto, the
other end of the spring 194 being attached to a second spring 195 which bears
against the inside 196 of the barrel 188. The axle 193 has a bar 197 attached
thereto. Said bar 197 forms a loose driving connection to the spool 191 through
a pin 298 secured to one end of the spool 191.
The shuttle 184 has a lip piece 198 with a hole 199 for the weft thread to pass
through for the purpose of guiding said thread close up to the knotting pins
as the shuttle passes through the shed to deliver the weft. The top plate of the
shuttle has the edges 100 (Figure 13) projecting slightly beyond the other parts
of the shuttle so as to enter the slots 101 of the shuttle guides 37.
TENSION DEVICE.
The bar 102 is mounted to rock upon a shaft 6; the end 103 of the bar 102
is provided with another bar 104 fixed at right angles to the bar 102 to which
are attached two rods 105 extending lengthwise of the machine. (Figure 22.)
Round said rods 105 each warp thread passes on its way previous to passing
through the hole 206 in a small bolt piece 107, which bolt piece passes through
a hole 208 in a bar 109. The end of the bolt 107 has a hole 210 in it through
which passes a weighted lever 211 to the piece 212, the projecting piece 212 has a
hole 213 which the end of the weighted lever 211, enters, the parts being so
arranged that the weighted lever 211 normally holds the head 214 of the bolt 107
close down upon the surface of the plate 109 thereby securely holding the warp
thread, which after passing through the hole 206 and bolt 107 passes down the
hole 315 to the creel (not shewn in the drawings). The requisite movement of
the lever 102 is obtained by an arm 116 keyed to the shaft 6, said arm having
at its end a roller which bears upon the cam 117. In order to finally lift the
tension bar 109 to allow the depressor to come right down, a roller 118 comes in
contact with the cam piece 119 secured to the cam plate 17, thus giving the
lever 102 a final lift by means of the hooked arm 220. When the bar 102 is
in its lowest position the weighted lever 211 strikes upon the bar 221, which
raises said lever 211 and together with it the bolt 107, and thereby allows the
free movement of the warp thread.
TAKE-UP MOTION, (Figure 1 and 3).
The take-up roller 222 is mounted on a shaft 223 provided with bearings upon
the main framing of the machine. An arm 124 rocks loosely on the shaft 223
and has attached to it a pawl 125 engaging with the teeth 326 of the ratchet
wheel 127. The other end of the rocking arm 124 has a connecting rod 128
connected to a rocking lever 129, rocking upon a pivot 130, and bearings secured
to the main frame of the machine. The other end 131 of the rocking lever 129
has a bent piece rocked by a roller 232 secured to the cam 18 whilst the other
end of the rocking lever 129 has a weight 233 which keeps the requisite amount
of tension upon the take-up roller 222, the pawl 134 is provided to prevent the
backward movement of the take-up roller.222.

page_text: The action of the machine is as follows:-
The warp from the creel is passed through the hole 315 in the plate 109,
thence through the hole 206 in the bolt 107, around the bars 105, thence up
through the hole 8 in the guide 7 away to the take-up roller 222.
Assuming the parts to be in the position as shewn in Figures 1, 2 and 24, the
guide arm 12 being a little behind the slip hook 50, the guide 7 shogs to the
left by means of the arm 21 secured on the shaft 23, carrying the warp thread
around the slip hook, and then comes forward to the left of the knotting pin 74
as shewn in Figure 25, and is shogged to the right by the arm 22 also mounted
on the shaft 23. The guide then returns to its original position slightly above
the slip hook 50. The depressor shaft 4 then turns, bringing with it the
depressor bar and depressors 49 into the position shewn in Figure 26 in which
it will be seen that the longer finger 335 of the depressor just engages the
portion 336 of the loop, taking the thread 336 between the other portions of
the loop 337 and 338. The depressor arm then comes down carrying with it
the thread 336 into the position shewn in Figure 27, and forming a loop 340
through which passes the shuttle 184, resting upon the wheels 142. The shuttle
is drawn through by means of the chain 145, sprocket wheel 149, pinion 153,
rack 154 and rack wheel 155, thus drawing the shuttle through the shed formed.
This will be seen more clearly by referring to Figure 16 in which it will be
seen that the portion of the warp 336 is compelled to pass along under the lower
portion of the bar 187 of the shuttle 184 by reason of the gear wheels 141 and 142.
Assuming the shuttle 184 to be drawn in the direction of the arrow shewn
in Figure 16 as the shuttle passes through the shed, the cam plate 178 on the
part 171 presses against the projecting portion 341 of the tumbler, thus bring-
ing the hooked end 133 to the right (Fig. 2) to receive the weft thread.
The said cam plate 178 is partly covered by the plate 183. When the shuttle
is travelling to the right, the left hand cam 180 is covered and inoperative.
On the return stroke the opposite cam 179 is covered, and the cam 180 is
inoperative.
The top plate 183 strikes against the tumblers and is pushed back by them.
This uncovers the cam piece 179 which depresses the heel of each tumbler
and causes the hook 133 thereof to move to the right to take the weft
thread. The tumbler remains in this position until the end of the plate 183
has passed it, when the tumbler falls back again into its original position. The
return of the tumblers to their normal position, carrying the loop of the weft
with them, is ensured by the projecting ends of the bar 172 in the manner
hereinafter explained.
The shuttle as it passes through the shed is guided by the edges 100 entering
the slot 301 of the guides 37, said guides being spaced apart so that the loops
can occupy a position between them. The shuttle having passed through the
shed passes into the guide piece 36 where it is lifted out of the way of the
mechanism until it is again required to be passed through the next row of
loops.
It is necessary to take up the slack thread formed in the return of the shuttle.
For this purpose the loop is taken up by the tension which is imparted to the
spring 194, said spring being capable of winding a sufficient length of the weft
upon the spool 191; the spool 191 can, however, rotate freely by reason of the
slipping of the spring 196 on the inner surface of the barrel 195, due to the
extra strain put upon the weft thread.
Referring now to the tumblers, these are forced to the left (Figure 2) by the
bar 172, the said bar being so shaped as to allow the tumblers sufficient clear-
ance for the requisite movement, and a guide bar 177 is provided to prevent
the tumblers from. fouling any projecting portions of the guide carrier. One
end of the said bar 172 curves outwards (Figs. 8 and 9) at each end of the shuttle
carrier and serves to force back the tumblers again into the position shewn in
Figure 2, and thus form the loop of the weft; the distance through which cach

page_text: tumbler can move being regulated by roller 108 and adjusting screw 230
(Figure 6), the bar 172 being likewise adjusted radially by the attendant to
allow the tumblers to be pushed more to the left and hold the extra loop formed
or vice versa, according to the size of mesh required. The depressor is then raised
into the position shewn in Figure 29, and is shogged back to its normal position
by the arm 60 striking against the roller 69 upon the arm 70 which is secured
to the main frame of the machine as described. The slip hook 50 then comes
forward and the tension bar 102 falls, so as to take up the portion of the warp
which forms the loop before described. The said slip hook in coming forward
is shogged to the left when the arm 71 upon shaft 5 strikes against the roller 72,
thus allowing the slip hook 50 to clear the knotting pins 74.
At this moment the slip hook passes slightly beyond the knotting pin 74 so
as to clear the loop, and strip the slip hooks, and the knotting pin is momen-
tarily encircled by the reduced loop, but hardly is this effected when the movable
knotting pins 75 are drawn up and disengage themselves both from the warp and
the weft threads, the latter of which are now held in the loops or loose knots
produced by the action of the slip hooks 50 and knotting pins 75 as described.
These loose knots are forced forward against the tumblers 132 and are tightened
by the curved bars or brushes 89. The mesh governor plate 207 then rises, and
the receiving pins 205 (which are arranged on the bar 106 slightly to one side
of the tumblers) are withdrawn. The plate 207 then sinks again, forcing back
the tumblers by means of the roller 108 pressing against their curved surfaces
and thereby throwing off the meshes on to the receiving pins 205. The receiver
drum 222 is revolved by the roller 232 striking against the arm 131, and thus
operating the rocking arm 124 and with it the pawl 125, which engages in the
ratchet teeth on the wheel 127. After this the weight 233 on the rocking arm
falls to take up the mesh formed.
As the shuttle carrier passes from left to right of the machine the cam piece 179
comes into play. The sliding bar 183 automatically moves backwards so as to
prevent the tumblers from falling back until they have received the weft, and
as the shuttle carrier moves in the reverse direction the cam surface 180 is
automatically uncovered, and the other end 179 is covered by the sliding bar 183,
which also prevents the tumblers from coming forward too near from their
return movement.
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:
