PROVISIONAL SPECIFICATION.
Improvements in Machinery for Manufacturing Wire Netting.
We FELIX HIPPOLYTE MONMON and ERNEST DORIGNY both of 24 Boulevard des
Capucines, Paris in the Republic of France Engineers do hereby declare the nature of
this invention to be as follows:-
This invention relates to an improved construction of machine for manufacturing
wire netting. The machine is operated by crank shafts having slotted heads which
engage with the crank pins in such a manner as to give a
"dwell" or "rest" to the
working beams to enable independent wire twisting and shifting motions to take place.
The wire bobbins are arranged in pairs side by side, or one above the other, either
vertically or horizontally. They are carried in couples in grooves, (on which they
slide) in a twisting frame which follows the movements of the twisting devices (which
consist of twisting pinions) so as to avoid counter-torsion of the wire.
The bobbins may be all moveable together or not and follow the movement of half
collars constituting part of the twisting devices. The movement given to the bobbins
may be such that they operate in curved or other lines of motion in forming the
netting. The bobbins have suitable guides on their frames which deliver the wire
from a higher point than the bobbins themselves.
The twisting devices consist of grooved fixed pinions having half collars suitably
operated to carry the wire.
'
The netting formed passes over a bar or beam so arranged as to have a rotary and
a sliding motion.

Improvements in Machinery for Manufacturing Wire Netting.
We, FELIX HIPPOLYTE MONMON and ERNEST DORIGNY both of 24 Boulevard des
Capucines, Paris, in the Republic of France, Engineers, 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 relates to an improved construction of machine for manufacturing
wire netting, the principal features of which are :
1. A connecting rod with an elongated slot and working-beams or side levers.
2. Grooved fixed pinions and movable half collars which pass from one pinion to
the next and back again.
3. Vertical bobbins in couples arranged on a carriage or turn-plate with a fixed
and independent wire-guide, the bobbins being capable of working altogether or half
at a time, and placed parallel and at right angles underneath the series of torsion
pinions which they follow in the twisting and sliding motion produced by their half
collars, so that, whilst the half collars execute their sliding movement in one direction
only, the bobbins arrive at the same result (that is to say, effect their shifting
movement) by different courses re-uniting by rectilinear or right angle turning
motions.
In the accompanying drawings Figures 1. and 2 represent a front elevation of an
apparatus on our system broken at three points: Figure 3 is an end elevation, and
Figures 4 and 5 a plan view of Figures 1 and 2.

page_text: In these drawings A is the framework of the apparatus which may be of any
suitable style. B B are the pinions capable of rotary and shifting motions (the rotary
being produced by means of racks, and the shifting by means of collar plates), C Caro
supports holding the bobbin-stands or creel-plates. D is the driving gear which
gives the starting motion. E is a cog-wheel driven by D and communicating by the
connecting rod E' an intermittent and rotary movement to the pinions and bobbins
through the pivoted working heams F their cranks and racks. E' is a connecting
rod having an elongated slot at one end and working on the pin w on the cog E is a
disc fixed upon the axle of E imparting through the connecting rod el, which has also
a slot at one end, during the rest of E the necessary intermittent motion for the
shifting of the half collars and bobbins. FF are the working-beams operating the
racks which turn the twisting piniors upwards and the bobbin-plates downwards in
such a manner as to avoid counter-torsion. is a supplementary connecting rod.

portion of the apparatus for shifting the bobbins more particularly described
hereafter with reference to Figs. 18 and 19. G is an endless screw (or worm-
gearing) working upon the pinion holders B to operate the half collars and "cloth"
beam H (over which the finished netting passes) by means of the carrier g which is
fastened to the collar-bars and on the movable part of the "cloth" beam. H is the
"cloth
beam consisting of an axle, and a casing sliding thereon in grooves, the
general motion of the "cloth" beam being produced, the rotary by an endless chain
gearing I and the sliding motion by the carrier I is an endless chain-gearing
having a continuous motion produced from the bevel gears y and z on the shaft of the
cog wheel E.

In these drawings J Jare stands supporting and carrying the bobbin-plates.
KK are plates turned by means of racks beneath and carrying with them, either in
grooves, or by means of a dove-tailed or T shaped projection which serves both as
a guide and a support, two bobbins, one of which can pass to and from the next plate
by a rectilinear motion, or by a right angle or single or double turn. bare the
bobbins arranged in couples on the bobbin plates K, either parallel to the set of
pinions and at right angles to their sliding motion (and in this case movable only
by halvos, Figs. 8 and 9) or in the direction of the sliding motion and at right
angles to the set of bobbins (all the bobbins in this case moving together, Figs. 6
and 7) the rows of plates being as many as desired, both in the direction of the length
and width of the apparatus. LI, are the rods communicating the rectilinear shifting
movement to the end bobbins, in the direction of the length of the apparatus.
M, M, are the transmitting rods at right angles to L, that is to say, in the direction of
the width of the apparatus, and of the plate-guides. N is the mechanism producing
the turning notion, and O is that producing the rectangular movement.
Figs. 18 and 19 will represent the movement mechanism of the bobbins as it is
here shown with the other parts removed.
Fig. 18 shows the method of obtaining the curved motion illustrated in Fig. 15,
and Fig. 19 the rectangular motion illustrated in Fig. 14.
The operating mechanism shown in Fig. 18 is composed of a rectangular frame f
which has secured to its ends four short racks 2, 2, 2, 2, which are parallel with its
sides. These racks 2, 2, 2, 2, engage with pinions 3, 3, 3, 3, which in their turn
engage with the racks 4, 4 and 5, 5 on the three sided frames 6 and 7 giving
them a movement at right angles to the movement of the racks 2.
The frame is cut at various points into racks 8 which engage with the pinions 9
that operate the bobbin stands,

page_text: Motion is imparted to the frame f' by the supplementary connecting rod f operated.
by the connecting rod e which is attached to it at the point 10. When this frame fl
is given its reciprocating motion the bobbins are carried from one case to the other by
means of the curved dove tail grooves 11, the frames 6 and 7 advancing them inward
parallel to each other until they may have changed for lower bobbins and vice versa.
In Fig. 19 the general construction is similar to Fig. 18, but instead of the rack3 8
and pinions 9, yoke shaped pieces 12 are employed which carry from one case to
the other rectangularly the upper bobbins which in this case travel in the straight
grooves 13. In place of the racks 22 being fixed to the frame f¹ they are permitted
a sliding movement on rods 14, 14, which consequently causes a delay in the
movement of the frames 6 and 7, and thus leaves room for the side movement of the
bobbins in the grooves 13 which is effected by the frame i before they push them in
toward each other.
Fig. 10 is an elevation representing the vertical bobbins placed one above the
other. In this drawing P is the plate supporting the vertically superposed bobbins ;
its extension R and the axle p carrying the upper fixed bobbin, the wire of which it
guides. Qis a guide fixed upon which is the axle fixed on the smaller sliding plate,
holding the lower bobbin X and serving to support the wire guide Q. The extension R
of the plate P serves as a support and as a wire-guide for the upper bobbin X.
XX or bare vertical bobbins, the only form which by reason of their height will
give the necessary space for charging them with sufficient wire to last for a days
work, for which reason we prefer them.
Nevertheless, as hobbins placed horizontally can be used, we represent them in
Fig 11, where they are operated in the same manner as the vertical bobbins, in the
positions and with the motions that we have described above, without which moreover
neither of them could be used.
Fig. 12 represents an elevation of a pinion T with its half collar ss. Fig. 13
being a plan of same.
Both the pinions and half collars have channels which admit of the passage of "
the wire.
Fig. 14 is a representation of the single rectangular motion indicated in Figs. 6
and 7. Fig. 15 is a representation of the simple turning motion. Fig. 16 represents
the simple and double turning motion. Fig. 17 represents the single and double
rectangular motion. These four figures show by dotted lines the backward and
forward movement of the bobbins, and their method of coming together again.
All these variations can be employed either separately or combined, as indicated
in Figs. 8 and 9. We would lay particular stress upon these motions as they form
an important part of our invention.
OPERATION OF THE APPARATUS.
It will be seen from the general design in Figs. 1, 2, 3 and 4, that as soon as the
machine is started the main wheel E moves the crank alone, the twisting apparatus
remaining stationary, whilst the crank shaft e¹ operates the shifting mechanism of the
bobbins and the half collars in placing them in position; this done, the crank e¹ works
independently while the crank E' operates the rotary mechanism of the pinions
and bobbins by means of the side-levers (working-beams) F F and racks, and so on.
The cloth beam H turns slowly and continuously, whilst its casing follows the
movement of the half collars.
We should remark here that this apparatus may comprise any desired number of
pinions and bobbins according to the width of the netting to be manufactured and
the size of the meshes. Our system achieves the following results :
1. The possibility of not charging the apparatus more than once a day.
2. The possibility of using wire of every quality and thickness which is impossible
with present-appliances, and
3. The avoidance of more than three fourths of manual labour.
We do not desire to restrict ourselves to the special method of construction before
described, which must necessarily vary under circumstances, but

page_text: Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what we
claim is :-
1. In a wire notting machine the employment of vertical or horizontal bobbins
placed side by side or one above another carried in couples in a twisting-stand (plate)
which is grooved or relieved, turning in the same direction as the twisting pinions for
the purpose of avoiding counter torsion; the said bobbins being movable altogether
or only by halves, but in either case only half of them passing from one plate to
the adjacent one to return to the first, thereby following exactly the motion of the
corresponding half collars, and this not only in the rectilinear movement of the
movable half collars of the pinion but in the different directions, that is to say, in
winding and reuniting by means of curved, straight, and rectangular motions to form
metallic netting, substantially as described and represented.
2. The fixed grooved pinions having the upper and lower half collars movable to
carry the wire, thus obtaining by means of two racks the maximum twisting power,
substantially as described and represented.
3. The independent bobbin-guides carrying the delivery point of the wire to a
point higher than the bobbins, substantially as described and represented.
4. The working beams operated by elongated slot cranks in such a manner as to
give a stoppage at a precise moment and of the necessary length for the independent
twisting and shifting motions, substantially as described and represented.
