Improvements in Weaving Selvages and in Apparatus therefor.
We, JOSEPH HARGATE CLIBRAN of Oldfield, Altrincham, in the County of
Chester, Nurseryman and GEORGE BROWNING of 137 Sussex Street, Lower
Broughton, Manchester, Mechanical Engineer do hereby declare the nature of this
invention to be as follows:-
When it is desirable to weave two or more widths of cloth on one loom at the
same time, we, when "drawing in" the warp, leave a vacant space in the healds and
reed of about three quarters of an inch wide and each weft thread is cut in the
center of this space and the ends of the weft are turned back, one to the left
and the other to the right, and drawn in between the warp threads of the next
"shed."
To accomplish the above we provide a pair of nippers which are operated by
means of a sliding bar and lever receiving motion from a cam on a cam-shaft which
is driven from the crank-shaft of the loom by suitable gearing.
The nippers close upon the weft when it is left by the reed.
In the end of the nippers is a vertical slot in which a knife slides, this knife
receives motion from a lever actuated by the sliding bar before mentioned and cuts
the weft while it is held by the nippers; the nippers and the knife are carried by
a bar which receives, up, down, forward and back motions from cams on the cam-
shaft before mentioned.
We also provide right and left hand hooks, these hooks are carried by a pair of
levers pivoted near their centers to a rocking piece and receiving, right, left, forward
and back motions from cams on the cam-shaft before mentioned.
The operations are as follows:-First, the hooks move forwards and enter the
shed about half an inch from the edges of the warp; second, the hooks move
in the shed towards the nippers and backwards into the acute angle of the shed ;
the weft being by this time cut by the knife and the ends held by the nippers
are now carried partly round the hooks and the hooks catch the weft and draw the
ends out of the nippers and in between the warp threads thus forming a perfect
double weft selvage.

We, JOSEPH HARGATE CLIBRAN, of Oldfield, Altrincham, in the County
of Chester, Nurseryman, and GEORGE BROWNING, of 137 Sussex Street, Lower
Broughton, Manchester, in the County of Lancaster, Mechanical Engineer, 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 the weaving of the inner selvages of narrow cloths where

deposit them in the next shed of the cloth.
The nippers A are placed at the end of an arm or lever E pivoted to a moving
bar or carriage F and receive from a cam or cams the necessary movements to
enable them to open to receive the thread; to advance forward; to close and grip
the thread and carry it round the hooks and afterwards to move backwards clear
of the reed. The nippers are formed of two jaws a al pivoted to the end of the
lever E which are held in a normal or closed position by the springs all a
A to and fro movement is imparted to the nippers A by the cam W acting on a
bowl or runner won the upper end of the pivoted arm which oscillates on the
centres e. And an up and down movement is imparted by the cam X acting
through the lever E'. The lever E' upon which the bowl rests when lifted by
the cam X lifts the arm E and the outer end of the moving bar or carriage F
which oscillates about the pivot, or it may be made to slide in a rectilinear path.
The jaws a a' of the nippers are caused to open by a rod G the end of which is
inclined and is pressed against an incline on the upper members of the nipper
jaws a a. The rod G is connected to a cranked lever g which is raised and lowered.
by the cam Y.
In the top jaw a of the nippers is placed a sliding knife or blade B which is
moved to and fro in a slot. The blade B moves up and down with the jaw a as it
opens and closes. It is also pivoted at 6 and is moved to and fro by the pin g' on
the rod G which slides in the slot 6' in the pivoted arm B₁ of the knife blade B.
At each side of the nippers A is placed a finger or hook C carried by the pivoted
arms or levers C¹. The pivots c which carry the arms C' are connected to a
moving or rocking frame or carriage H whereby the fingers or hooks C may be
moved to and fro in two or three directions. The two arms C¹ are geared or
connected together by the tongue and groove c' so as to move together synchronously..
The lever C extends up from the arm C' to the cam Z which has both a peripheral
and a side face, the former of which bears against the bowl or runner and the side
face against the runner. The action of the side face is to cause the lever. C"
and arms C¹ to move upon the pivots e and the action of the peripheral face of the
cam is to cause the frame or carriage H to move upon the pivots h. An extended'
view of the peripheral face of the cam Z is shown in Fig. 9,

about three quarters of an inch wide and in this space between the warp yarns
the nippers A are placed. When at rest between each shot or pick of the shuttle
the apparatus is in the position shown in the drawings. After each pick or shot
when the weft yarn has been beaten up by the reed and the shed changed the
nippers A and the hooks C are caused to move forward simultaneously towards
the reed. The nippers A by the cam W pressing against the bowl or runner w on
the upper end of the arm E and the hooks C by the peripheral face of the cam Z
on the runner of the lever C". When the nippers have been advanced so that
the two jaws a a' embrace the weft yarn last placed in the shed the rod G
is raised by the cam Y, allowing the jaws to close and at the same time
drawing the knife B back by means of the pin g' sliding in the slot 6 of the knife
lever B¹.
When the yarn has been cut by the knife B the hooks or fingers C which are in
the position shown are gradually lowered until they rest upon the top warp threads
of the shed and press down the threads upon which they rest so that the points are
about the centre of the angle of the shed. They are then by the action of the side
face of the cam Z drawn into the shed towards the nippers. At the same time the
nippers which have been gradually raised by the cam X fall slightly and are moved
back laying the weft thread over the hooks. The hooks C then receive a com-
pound movement from the two faces of the cam Z and are then drawn back through
the shed drawing the cut ends of the weft threads from between the jaws a a¹ of
the nippers and laying them into the shed thus forming a perfect double weft
selvage. The hooks C and the nippers A are then returned to their original
position as shown and after each pick or shot of the shuttle the same operation is
repeated.
We would here remark that we are acquainted with the Specification of Letters
Patent granted to William Simpson No. 8056 of 1890, and we wish it to be
understood that we do not claim anything which is described and claimed therein.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. An apparatus for forming inner selvages in the weaving of cloth having a pair
of nippers to take hold of or grip the weft thread a knife to sever the thread and a
pair of hooks to take hold of the ends of the severed thread and draw them back
into the shed substantially as described.
2. An apparatus for forming selvages in the weaving of cotton and other cloths
constructed and arranged substantially as described and shown.

We, JOSEPH HARGATE CLIBRAN, of Oldfield, Altrincham, in the County
of Chester, Nurseryman, and GEORGE BROWNING, of 137 Sussex Street, Lower
Broughton, Manchester, in the County of Lancaster, Mechanical Engineer, 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 the weaving of the inner selvages of narrow cloths where
two or more widths of cloth are woven upon broad looms and is designed with the
object of producing a better and stronger selvage than what is produced by the
present system of crossing the warp threads between the picks.
It consists essentially in forming the selvages by cutting the weft thread and
turning the two ends in opposite directions back again into the shed round

page_text: the shed.
It will be fully described with reference to the accompanying drawings in which
as an example the apparatus is shown as attached to the top rail of a calico
loom.
Fig. 1, is an enlarged diagram of cloths with selvage woven according to our
invention.

The apparatus is constructed with a pair of nippers A to first seize the weft
thread and hold it firmly; a knife B to cut it and two fingers or hooks C which
afterwards take the two cut ends and turning them back round the warp thread
deposit them in the next shed of the cloth.
The nippers A are placed at the end of an arm or lever E pivoted to a moving
bar or carriage F and receive from a cam or cams the necessary movements to
enable them to open to receive the thread; to advance forward; to close and grip
the thread and carry it round the hooks and afterwards to move backwards clear
of the reed. The nippers are formed of two jaws a al pivoted to the end of the
lever E which are held in a normal or closed position by the springs all all
A to and fro movement is imparted to the nippers A by the cam W acting on a
bowl or runner w on the upper end of the pivoted arm E which oscillates on the
centres e. And an up and down movement imparted by the cam X acting
through the lever E. The lever E' upon which the bowl a rests when lifted by
the cam X lifts the arm E and the outer end of the moving bar or carriage F
which oscillates about the pivot, or it may be made to slide in a rectilinear path.
The jaws a a¹ of the nippers are caused to open by a rod G the end of which is
inclined and is pressed against an incline on the upper members of the nipper
jaws a a. The rod G is connected to a cranked lever g which is raised and lowered
by the cam Y.
In the top jaw a of the nippers is placed a sliding knife or blade B which is
moved to and fro in a slot. The blade B moves up and down with the jaw a as it
opens and closes. It is also pivoted at 6 and is moved to and fro by the pin g' on
the rod G which slides in the slot b¹ in the pivoted arm B' of the knife blade B.
At each side of the nippers A is placed a finger or hook C carried by the pivoted
arms or levers C¹. The pivots e which carry the arms C¹ are connected to a
moving or rocking frame or carriage H whereby the fingers or hooks C may be
moved to and fro in two or three directions. The two arms C¹ are geared or
connected together by the tongue and groove c' so as to move together synchronously.
The lever C extends up from the arm C' to the cam Z which has both a peripheral
and a side face, the former of which bears against the bowl or runner 2 and the side
face against the runner :¹. The action of the side face is to cause the lever C"
and arms C' to move upon the pivots c and the action of the peripheral face of the
cam is to cause the frame or carriage H to move upon the pivots h. An extended
view of the peripheral face of the cam Z is shown in Fig. 9.
The cams W X. Y. Z. are all on one shaft and are actuated by a chain on to the
chain wheel V driven by the crank shaft of the loom.
The operations are as follows:-
:-
When drawing in the warp yarns a vacant space is left in the healds and reeds
about three quarters of an inch wide and in this space between the warp yarns
the nippers A are placed. When at rest between each shot or pick of the shuttle

nippers A and the hooks C are caused to move forward simultaneously towards
the reed. The nippers A by the cam W pressing against the bowl or runner w on
the upper end of the arm E and the hooks C by the peripheral face of the cam Z
on the runner z of the lever C. When the nippers have been advanced so that
the two jaws a a¹ embrace the weft yarn last placed in the shed the rod G
is raised by the cam Y, allowing the jaws to close and at the same time
drawing the knife B back by means of the pin g' sliding in the slot b' of the knife.
lever B¹.
When the yarn has been cut by the knife B the hooks or fingers C which are in
the position shown are gradually lowered until they rest upon the top warp threads
of the shed and press down the threads upon which they rest so that the points are
about the centre of the angle of the shed. They are then by the action of the side
face of the cam Z drawn into the shed towards the nippers. At the same time the
nippers which have been gradually raised by the cam X fall slightly and are moved
back laying the weft thread over the hooks. The hooks C then receive a com-
pound movement from the two faces of the cam Z and are then drawn back through
the shed drawing the cut ends of the weft threads from between the jaws a a¹ of
the nippers and laying them into the shed thus forming a perfect double weft
selvage. The hooks C and the nippers A are then returned to their original
position as shown and after each pick or shot of the shuttle the same operation is
repeated.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. The method of forming inner selvages upon woven cloth by cutting each weft
thread and turning the two ends in opposite directions back again into the shed
round the angle formed by the two crossing warp threads respectively substantially
as described.
2. A woven cloth having a selvage formed of a cut end of thread turned back
into the shed substantially as described and shown.
3. An apparatus for forming inner selvages in the weaving of cloth having a pair
of nippers to take hold of or grip the weft thread a knife to sever the thread and a
pair of hooks to take hold of the ends of the severed thread and draw them back
into the shed substantially as described.
4. An apparatus for forming selvages in the weaving of cotton and other cloths
