Improvements in Machines for the Manufacture of Coiled Wire
Fabric.
I, HENRY LIEBERT, of the Fum of John Holroyd & Co Lad. o: Tomhason
Street, Hulme, Manchester, in the County of Lancaster, Engineer, do hereby
declare the nature of this invention to be as follows
This invention elutes to improvements in machines for the manufacture of
coiled wire fabe, the objects being, firstly, to provide means whereby any number
of coils consisting of more than two wies, sty six, can be woven close together in
alternate fashion; secondly, to provide means whereby the wine when i un from the
Cole between the vertical pins, are presented from leaving the box into which
they are run, thudly, to provide means whereby the wires when run from the
coiler mio the box are prevented from over hooting and thus the fabric woven
with straighter edges, than heretofore has been the case.
In carrying out the first part of my invention I dispense with the houzontal pin
bais heictofore used for holding the coil in the box and employ in hen thereof on
each side of the coil on the said box a knife edged plate adapted to advance
towards and retire from the coil on coils in the box as may be requned to
espectively hold and release the same alternately during the operation of weaving.
Each of the said plates is actuated by a cam and connections as follows-
Upon the bed or frame of the machine is mounted in sunt ible beatings along
each side of the said coil box a shaft upon which are fixed a suitable number of
levers then free ends being connected by means of swivel blocks, screwed spindles
and nuts to the said plates, which latter are guided at the ends by studs passing
though slots in the same
At the back end of the coil box is employed to rotate in suitable beatings a
cross shaft which icceives its motion from the head on driving end of the machine
by means of a chain and chain wheels Upon this shaft are fixed two cams each
in connection with a slide, the upper end of each slide being furnished with an
anti-friction bowl aud the lower end placed under the influence of a sping
which causes the said bowls to ide on the periphery of the said cans and said
lower end being also connected to levers fixed respectively to the afores ud
longitudinal shafts.
When weaving coils with a large number of wes, say "sixes," owing to the
increase in the i kness of the fabrir the front knife edged plate is arranged to
advance a less distance than otherwise as required to gap the coil which is effected
by employing on the respective cam slide an additional anti-fuction bowl m
connection with another cam mounted upon à colla on the said cross shaft and
shid under the said bowl by means of a clutch arrangement and from the same by a
bevelled projection on the re-pective cam slide, which latter on being raised by its
main cam causes the said projection to come into contact with the end of the
additional cam and throw it out of contact with its bowl. The sud additional cam
is kept in its working position by a spring having a bevelled projection bearing
ngainst the end of the cam boss.
In carrying out the second part of my invention in lieu of forming the sand
vertical pins straight, I bend or crank then slightly preferably so as to form an
mline under which the coil when being run to the box, passes and which ieting
|as a shoulder prevents the wie working out of the box.

page_text: In carrying out the last part of my invention instead of cutting the wire and
interrupting the feeding of the same at or about the same time, I stop the feed of
the wire a moment before the cutting of the same takes place, by accordingly
positioning the projection on the chain which causes the feed rollers to be thrown
out of gear.

Improvements in Machines for the Manufacture of Coiled Wire
Fabric.
I, HENRY LIEBERT, of the Firm of John Holroyd & Co. Ltd. of Tomlinson
Street, Iluline, Manchester, in the County of Lancaster, Engineer, do hereby
declare the nature of this invention and in what manuer the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to improvements in machines for the manufacture of
coiled wire fabric, the objects being, firstly, to provide means whereby any number
of coils consisting of more than two wires, say six, can be woven close together in
alternate fashion, secondly, to provide means whereby the we when run from the
coile between the vertical pins, are prevented from leaving the box into which
they are run; thudly, to provide means whereby the wires when i un from the
coiler into the box are prevented from over shooting and thus the fabric woven with
straighter edges, thau heretofore has been the case.
And in order that my invention may be more fully understood I have caused to
be appended hereunto two sheets of diawings marked with letters of reference
indicating like parts in the various figmes.
Fig. 1, Sheet 1, 18 a front view, Fig 2 a plan, and Fig. 3 a back end view at a
reduced scale of a wire coiling machine provided with my improvements
Fig. 4 is a sectional back end view at an enlarged scale and Figs. 5 & 6 side
views of the cams actuating the knife edged plates
Figs. 7, 8, 11 & 14, Sheet II, are cud views of the coiling box at an enlarged
scale showing in cro-s soction the various positions of the same and the knife
edged plates and pin bat.
Figs 9, 12 & 16 are plans and Figs. 10 & 13 sectional side views of Fige. 8, 11
& 14 respectively.
a 18 the coil box, b, b' are the knife edged plates, c the pin bat, d, d' the feed
rollere.
In carrying out the first part of my invention I dispense with the horizontal pin
bars heretofore used for holding the coil or coils in the box and employ in lieu
thereof on each side of the coil or coils a' on the box a, a hmfe edged plate b, b¹,
adapted to advance towards and retire from the coil or coils a' as may be requned
to respectively hold and release the same alternately during the operation of
weaving as hereinafter fully described. Each of the plates b, 6' 18 actuated by a
came, e respectively and connections as follows,―
Upon the bed or frame f of the machine is mounted in suitable bearings y, g', g³
along each side of the coil box a, a shaft h, respectively, upon which are fixed a
Buitable number of levers 1, 1'. The fee ends of the latter by means of swivel
blocks k,, screwed spindles and nuts 1, l', are connected to the plates b, b', which
are guided at the ends by studs passing through slots formed in plates &
Becured to the box a. The said plates prevent the hufe edged plates, being
lifted by the fabric and the studs from moving too fai aud damaging the
pins cl

page_text: At the back end of the coil box a is employed to rotate in suitable bearings m, mn,
a cross shaft n, which receives its motion from the head or driving end of the
machine by means of a chain o and chain wheels o', o'. Upon this shaft are fixed
two cams e, e', soo more particularly Figs. 4, 5 & 6, adapted to actuate the
slides p, prespectively, the upper end of each slide being furnished with an anti-
friction bowl p' & p' and the lower end placed under the influence of a spring p',
which causes the said bowls to ride on the periphery of the said cams, the said
lower ends being each also connected to levers q, q' fixed respectively to the
longitudinal shafts h, h².
The mechanism so far described serves to weave single coils and operates as
follows;-
At the commencement of the operation the box a, the knife edged plates b, b¹
aud the cam e, e' are in the positions as shown in Figs. 4, 5, 6 & 7, respectively,
.e. the knife edged plates b, b' are in their inner positions ready to receive and hold
the first coil to be formed in its proper position.
After the first coil has been formed, the vertical pins o' are moved as usual, and
the incline of the cam e, Fig. 5, having arrived below the bowl p³, the spring p¹
will cause the bowl p to ride upon the inner part of the cam periphery. Whilst
this change is taking place the incline of the other cam e', Fig. 6, has arrived
under the bowl p and lifts the slide pl, which causes the plate b to advance and
push the coil foined against the pins c', whilst the other plate 6' in the meantime
is caused to recede into position shown in Figs. 8, 0 & 10 As will be seen
from Fig. 8 the knife edge of the plate bis in contact with the pins c' and
that of being clear, the coil woven is prevented from being pulled out of the
box a.
On the further rotation of the cams e & e the knife edged plates h, bare
brought back into the positious as shown in Fig. 7, and a second coil is run into
the first coil in the box a. After this second coil has been formed, the motion of
the knife edged plates b, b¹ is reversed and the plates are brought into the position
shown in Figs. 11, 12 & 13, i.e. the plate b¹ is positioned against the pins c' and the
plate clear of the coil a' so that the second coil is held in the box a whilst the
first coil is raised as shown in Figs. 11 & 13. To effect the raising of the first coil
formed sinall weights are attached thereto as usual and after a few leet of fabric
has been woven the said weights are removed, the weight of the fabric being
enough to raise the coil as they are woven. When the coil has been raised the
knife edged plates b, b' are caused to return to their normal positions as shown in
Fig. 7.
Referring to Figs. 14 & 15, when weaving coils with a large number of wines,
say "sixes," owing to the increase in the thickness of tho fabric the front knifo
edged plate b is caused to advance a less distance than otherwise is required to
gup the coil a which is effected by employing ou the respective cam slide p an
additional anti-friction bowl p', see Figs. 4 & 5, operating in connection with
another cam mounted upon a collar e on the cross shaft n and slid under the
bowl p by means of the usual clutch arrangement, see also Figs. 2 & 3, and
away from the same by a bevelled projection e' on the cam slide p, which latter on
being raised by its main cam e causes the projection e' to come into contact with
the end of the additional came and throw it out of contact with the bowl p. The
cam is kept in its positions by a spring arm n' having a bevelled projection
engaging in recesses A³ in the boss of the came.
carrying out the second part of my invention, in lieu of forming the vertical
coil pins c¹ straight, 1 bend or crank them slightly near their extremity as shown
in Fig. 13, preferably so as to form an incline under which the first coil a' when
being run into the box a, passes and which acting as a shoulder, prevents it
working out of the box.
In carrying out the last part of my invention and referring to Fig. 2, instead of
cutting the wire and interrupting the feeding of the same at or about the same time,
I stop the feed of the wire a moment before the cutting of the same takes place, by
'

page_text: accordingly positioning the projection of on the chatu o which causes the fred
ollers d, to be thrown out of gear.
Having now particularly described and ascertained the nature of my said inveu-
tion, and in what manner the same is to be performed, I declare that what I
clain, is
-
1st. In a machine for the manufacture of coiled wire fabric, a bar c, having
vertical pius c in combination with knife edged plates b, one of which 18
employed at each side of the said pins and adapted to hold and release the coil
or coils in the box a, substantially as and in the manner herein before set forth.
2nd. In a machine for the manufacture of coiled wire fabric, the pins c¹ formed
with a shoulder or cranked part c, substantially as and for the purpose set forth.
3rd. In machines for the manufacture of coiled wire fabic wherein the feed of
the wire is interrupted by means of a projection upon a travelling chain o, eo
positioning the said projection o* that the feeding of the wire is interrupted
immediately before it is cut off for the purpose substantially as set forth
4th. In a machine for the manufacture of coiled wire fabric, the general
construction and combination of parts constituting my improvements operating
substantially as and for the purpose set forth.
