Whereas the said William Campion is the Patentee of certain improvements in
this class of machinery under Letters Patent dated 21st November 1879 N° 4736
for Improvements in machinery and apparatus to be employed in the manufacture
of close or open fabrics.
Now we have invented certain improvements which involve an entirely new
arrangement of the machine together with different motions whereby less friction
is put upon the threads and the machine is capable of being utilized for the
manufacture of very fine fabrics.
The machine consists of two end standards with one or more intermediate
supports the whole being firmly secured to one or more tie bars in the usual way
of constructing carcases of machines.
At the back of the machine a bracket is fixed upon the standards and supports
which receive a rocking axle shaft to which is secured the needle bar arms.
!
These arms are so shaped as to admit of the cam shaft passing through a ring
as it were forming part of the needle bar arm which arm is then extended from
the ring to the needle bar to which it is secured. Upon this ring are; secured
trucks. These trucks ride upon suitably shaped cams and counter cams secured;
to the cam shaft which cams and counter cams give the necessary motion to the
needle bar.
:
ང་
Upon the needle bar bearded needles are secured by plates in the usual way.
These needles pass through ordinary shaped sinkers cast at both ends.
One end of the sinker is secured to a sinker bar which is fastened to a right
angle truck bearing lever the truck end of which riding upon cams and secured to
the cam shaft which cams give a backward and forward motion to the sinkers.
Above the sinkers an independent presser bar is arranged which is secured to
truck bearing levers such levers being secured to a rocking axle shaft just below

page_text: the sinker bar rocking axle shaft-This presser bar also has a backward and
forward motion given to it by means of cams secured to the cam shaft.
Either counter cams or springs may be used in counteracting the sinker bar and
presser bar.
By this improved arrangement of the independent actions of the presser bar and
sinker bar less friction is put upon the threads and thus very fine silk can be
worked to a great advantage.
Above the needle bar one or more guide bars are arranged.
These bars work in a forked bracket in which a hole is drilled just above the
guide bar-A steel pin is secured to the guide bar such pin passing through the
hole referred to. The forked bracket is then secured to an arm by means of
the steel pin passing through a hole in the arm.
A small slotted hole is made at the top of the forked bracket by means of which
the guide bar can be tipped.
The arm referred to is then secured to a bracket which is fastened to the guide
bar rocking axle shaft.
The arms are so fastened on to the bracket as to be capable of being adjusted up
and down to give the necessary depth to the guides in the needles.
The motion to the guides is obtained by means of a curved lever fastened to the
guide bar rocking axle shaft at one end the other end being slotted. Another
double armed truck bearing lever is then threaded upon the needle bar rocking
axle shaft which works loosely upon that shaft-one end of that lever being also
slotted and carrying a truck the other end carrying a truck alone. The slots in
each of the levers are arranged side by side and are exactly the same size.
A square bit (upon which is secured an axle and truck) rides up and down in these
slots and it is adjustable at any position in the slots by means of a lock nut which
secures the square bit to one of the slots in the levers the other slot being left to
work freely upon the square bit.
The double armed truck bearing levér carries two trucks which ride upon
suitably shaped cams and counter cams which give the necessary motion to the
guide bars.
By the arrangement above described a great advantage is gained by being able
to reduce or extend the motion of the guide bars by adjusting the square bit
working in the slots by means of the lock nut without having to alter the cams.
The guide bars receive endway motion by means of studs representing so many
gaits being secured in a wheel by means of screws--This wheel is revolved by
means of a worm fastened to the cam shaft which works in a toothed wheel which
is fastened to the same shaft as the stud wheel is fastened.
The ordinary levers and springs are used for governing and operating the guide
bars one end of the lever riding upon the studs by means of which the guide bars
work.
Above the guides the ordinary sley is provided to guide the threads.
The necessary beam tackle is also arranged for carrying the beams above the
machine.
A work beam is also arranged in front of the machine together with a hand
wheel shaft carrying two hand wheels.
The ordinary belt power tackle and fast and loose pullies are arranged to stop
and start the machine.

We, HENRY BLACKFORD PAYNE, of Wyvill Terrace Hyson Green in the Town
and County of the Town of Nottinghain Lace Manufacturer, and WILLIAM
CAMPION of 57 Bovill Street Radford in the Town and County of the Town of
Nottingham, Machinist, 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 :-
The machine consists of two end standards with one or more intermediate
supports the whole being firmly secured to one or more tie bars in the usual
way of constructing carcases of machines.
:
At the back of the machine a bracket is fixed upon the standards and supports
which feceive a rocking axle shaft to which is secured the needle bar arms.
These arms are so shaped as to admit of the cam shaft passing through a ring
as it were forming part of the needle bar arm, which arm is then extended from
the ring to the needle bar to which it is secured. Upon this ring are secured
trucks. These trucks ride upon suitably shaped cams and counter cams, secured
to the cam shaft, which cams and counter cams give the necessary motion to the
needle bar.
Upon the needle bar bearded needles are secured by plates in the usual way.'
These needles pass through ordinary shaped sinkers cast at both ends.
One end of the sinker is secured to a sinker bar, which is fastened to a cranked
truck bearing lever, the truck end of which riding upon cams secured to the cam
shaft which cams give a backward and forward motion to the sinkers.
Above the sinkers an independent presser bar is arranged which is secured to
truck bearing levers, such levers being secured to a rocking axle shaft just below
the sinker bar rocking axle shaft. This presser bar also has a backward and
forward motion given to it by means of cams secured to the cam shaft.
Either counter cams or springs may be used in counteracting the sinker bar and
presser bar.
By this improved arrangement of the independent actions of the presser bar and
sinker bar, less friction is put upon the threads and thus very fine silk can be
worked to a great advantage.
•
Above the needle bar one or more guide bars are arranged.
These bars work in forked brackets in which a hole is drilled just above the
guide bar A steel pin is secured to the guide bar, such pin passing through the
hole referred to. The forked bracket is then secured to an arm by means of
the steel pin passing through a hole in the arm, together with screws to secure the
forked bracket in the required position.

DESCRIPTION OF THE DRAWINGS.
Our improved machine is constructed as follows reference being made to the
drawings hereto annexed.
The carcase or frame of the machine has two end standards a with or without
one, two or more intermediate bearings or supports..
These standards bearings or supports are held in position and properly secured
by means of one, two or more tie bars b.
The horizontal shafts of the machine are the cam shaft c needle bar rocking axle
shaft d presser bar rocking axle shaft e, sinker bar, rocking axle shaft f guide bar
rocking axle shaft g and the hand wheel shaft h.
There are also horizontal bars to the machine which are properly secured to
each of their respective rocking axle shafts by suitably shaped levers. These bars
are as follows:-
1st The needle bar d. This bar is connected
shaft d by means of a truck bearing lever d².
allow of the cam shaft c passing through it and
to which it is secured. This lever d² is provided
with its respective rocking axle
This lever d² is so shaped as to
then passes to the needle bar d'
with trucks, which ride upon.the

page_text: surface of a suitably shaped cam Figure 3 and counter cam Figure 4 affixed to the
cam shaft c which impart an up and down motion to the needle bar d'.
2nd The presser bar e¹. This bar which comes in contact with and presses the
beards of the needles is supported upon a suitably shaped truck bearing lever e
the top end of which carries a truck such lever being fastened to its respective
rocking axle shaft e, and receiving its motion from properly shaped cams Figure 5.
3rd The sinker bar f¹. This bar is secured to one end of a double truck bearing
lever f³ fixed to its respective rocking axle shaft f one end coming in contact with
cam Figure 6 secured to the cam shaft c which cam gives a backward and forward
motion to the sinkers f³ cast in leads and fastened on the face of the bar f¹ such
sinkers securing the loops formed on the bearded needles.
This sinker lever may either be counteracted by means of cams or springs.
The needles rise and fall in these sinkers such sinkers forming a bed upon which
the work rests.
Below the sinkers a roller j is provided to receive the fabric.
Suitable levers g¹ and forked arms 92 are secured to the guide bar rocking axle
shaft g to which are also secured as many guide bars g³ as are required with pins g
secured to them such pins 9 passing through the holes in the forked arms g³ and
levers g¹. The guide bars g³ receive end way motion by means of springs at one
end of each bar the other end of each bar being connected to a rod g which rod is
fixed to a lever 96 this lever gº moves on a centre g' the bottom end of the lever
resting on a stud wheel 98. The wheel 98 has studs g³ in it secured by means of
set screws g10 which can be removed and replaced at will and may be of various
sizes being so arranged as to form the different cam surfaces required to give
endway motion to the bars.
The stud wheel gs is fixed on the shaft g¹¹ upon which a worm wheel g¹² is fixed.
A worm g¹³ fixed on the cam shaft c giving motion to the worm wheel g₁² and stud
wheel ge the different rises upon which operate upon the levers go to actuate the
guide bars gs. The studs g³ are placed in two or more rows in each wheel each
stud being secured by a screw glo and capable of being removed at will.
The guide bars g³ receive their motion by means of the lever g4 secured to the
guide bar rocking axle shaft g at one end the other end having a slot formed in it.
which is connected to the double truck bearing angular lever g¹³. This lever g¹5
has a similar slot formed in it at that end which is connected to the, lever g¹. The
slots of both levers g¹ and g15 are placed side by side. An axle glo which passes
through both slots is then secured to the slot of lever g" by means of a lock nut
and upon this axle a small square piece of metal 9" is threaded which fits nicely in
the slot of the lever g¹ A truck is then placed upon an independent axle fixed to
the lever g15 which truck rides on the surface of the cam Figure 7-the other
arm of the lever 15 also carries a truck which rides upon the surface of a counter
cam Figure 8.
By the construction and arrangement of the levers g14 and go in this way the
backward and forward motion of the guide bars can be extended or reduced by
raising or lowering by means of the lock nut the axle carrying the square piece g¹7
which fits and rides up and down the slot of the lever g16.
Above the machine the necessary beam tackle k is provided to receive the beams
of yarn to supply the needles.
The special advantages resulting from the above described improved arrangement
and construction of knitted warp machinery consist in the various motions being
shortened in order to gain speed steady the action of the parts and reduce the
friction upon the threads.
The several movements of the parts are as follows:-
The needle bar d' rises vertically about half its motion. The lapping of
its threads upon the needles is then made by the guide bars g³ moved to and
fro by means of the levers g¹, 914, and g¹s actuated by the cams Figures 7 and 8.
The needles then rise to their full extent to pass the laps under the beards of
the needles, they then descend and just as the beards of the needles enter the

page_text: ⋅
sinkers f³, the presser bar e¹ then presses the beards into the eyes of the needles
and the work is then knocked over. The sinkers f³ then move back and forward
in order to secure the last loops made.
By giving independent motion to the presser bar and sinker bar the double
friction on the threads caused by combining the two bars in one is avoided and
thus very fine silk can be used to great advantage.
The improved combined movements or actions and arrangement of the presser
bar e sinker bar fl guide bars 93 and the other parts of the machine, may be
arranged to work in conjunction with the bearded needles working either vertically
as shown or horizontally or in any other position if desired.
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 we
make no claim to any of the parts separately which are well known and in
common use but what we claim is :
1. The improved combined movements or actions of the presser bar e¹ sinker,
bar f¹ and guide bars g³ acting in conjunction with bearded needles either working
vertically as shown or horizontally or in any other position if desired as applied to
straight machines substantially as and for the purpose hereinbefore described and
illustrated by the drawings hereto annexed.
2. The improved adjustable action and arrangement of the compound levers g¹4
and g¹³ for extending and shortening the action of the guide bars g³ substantially
as herein before described and represented in the drawings annexed.
3. The improved method of mounting the guide bars g³ upon the forked
brackets g whereby the forked bracket forms its own tipper to adjust the guide
bars substantially as described.
4. The improved general arrangement combination and construction of knitted
warp machinery where two or more guide bars are used substantially as described
and represented in the drawings annexed.
