Warp Fabrics.
I, HENRY BLACKFORD PAYNE of Wyvill Terrace, Hyson Green, in the Town
and County of the Town of Nottingham Lace Manufacturer do hereby declare
the nature of my invention for "IMPROVEMENTS IN MACHINERY FOR THE MANU-
FACTURE OF KNITTED WARP FABRICS" to be as follows:
My improvements are applicable to what is commonly known by the name of a
Warp Machine by means of which improvements the mechanism is simplified and
I am thus enabled to drive the machine faster.
My improved machine is constructed as follows:-
The carcase or frame of the machine has two end standards with or without one
two or more intermediate bearings or supports.
These standards, bearings and supports are held in position and properly secured
by means of one two or more tie bars.
The horizontal shafts of the machine are-The cam shaft-needle bar rocking
axle shaft-presser bar rocking axle shaft-point bar rocking axle shaft-guide
bar rocking axle shaft-and the hand wheel shaft.
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-This bar is connected with its respective rocking axle
shaft by means of a truck bearing lever. This lever is so shaped as to allow of the
cam shaft passing through it and then passes to the needle bar to which it is
secured. This lever is provided with trucks which ride upon the surface of a
suitably shaped cam and counter cam affixed to the cam shaft which impart motion
to the needle bar.
2nd The presser bar-This bar which comes in contact with the beards of the
needles is supported upon a suitably shaped truck bearing lever which is fastened
to its respective rocking axle shaft such lever receiving its motion from properly
shaped cams.
3rd The point bar. This bar is secured to one end of a double truck bearing
lever fixed to its respective rocking axle shaft the other end coming in contact with
cams secured to the cam shaft which cams give motion to the points cast in leads
and fastened on the face of the bar such points securing the loops formed on the
bearded

upon
Suitable levers and forked arms are secured to the guide bar rocking axle shaft
to which are also secured as many guide bars as are required with pins secured to
them such pins passing through holes in the forked arms.
The guide bars receive
endway motion by means of springs levers and wheels with studs in, such studs
are placed in two or more rows in each wheel each stud being secured by a seves
and capable of being removed at will.
The guide bars receive their motion by means of a truck bearing lever secured
to the guide bar rocking axle shaft at one end, the truck end riding upon cams
which give the necessary motion.
Above the machine the necessary beam tackle is provided to receive the beams
of yarn to supply the needles.

Warp Fabrics.
I HENRY BLACKFORD PAYNE of Wyvill Terrace Hyson Green in the Town and
County of the Town of Nottingham Lace Manufacturer 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:-
My improvements are applicable to what is commonly known by the name of a
"Warp Machine" by means of which improvements the mechanism is simplified
and I am thus enabled to drive the machine faster.
My 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 a with or without
one two or more intermediate bearings or supports.
These standards bearings and supports are held in position and properly secured
by means of one two or more tie bars b b.
The horizontal shafts of the machine are, the cam shaft c, needle bar rocking
axle shaft d, presser bar rocking axle shaft e, point 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 d¹. This bar is connected with its respective rocking axle
shaft d by means of a truck bearing lever d². This lever d² is so shaped as to
allow of the cam shaft c. passing through it and then passes to the needle bar d¹ to
which it is secured. This lever d² is provided with trucks which ride upon the
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 d¹.
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 e³
which is fastened to its respective rocking axle shaft e such lever receiving its
motion from properly shaped cams Figure 5.
3rd The point bar f¹. This bar is secured to one end of a double truck bearing
lever f² fixed to its respective rocking axle shaft f the other end coming in
contact with cams Figure 6,-secured to the cam shaft c which cams give a back-
ward and forward motion to the points cast in leads and fastened on the face of
the bar f1 such points securing the loops formed on the bearded needles.
Just below the point bar fi there is a stationary sley i fixed to a bar i which is
supported on brackets 2. The needles rise and fall in this sley such sley forming
bed upon which the work rests.
Below the sley i a roller j is provided to receive the fabric.
Suitable levers g' and forked arms g' 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 g* passing through holes in the forked arms g and
levers g'. The guide bars g receive end way motion by means of springs at one

resting on a stud wheel g. The wheel g³ has studs in it secured by means of set
fixed to a lever g6, this lever g" moves on a centre g' the bottom end of the lever
being so arranged as to form the different cam surfaces required to give endway 5

of yarn k¹ to supply the needles.
and construction of knitted warp machinery consist in the various motions being
The special advantages resulting from the above described improved arrangement
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 d¹ rises vertically about half its motion the lapping of the threads
upon the needles is then made by the guide bars g³ moved to and fro by means of
the lever g¹¹ actuated by the cams Figures 7 and 8-The needles 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 points f* the presser bar e¹ then presses
the beards into the eyes of the needles and the work is then knocked over. The
points f* then move back and forward in order to secure the last loops made.
By giving independent motion to the presser bar and point or sinker bar the
double friction of the threads caused by combining the two bars in one is avoided
and thus very fine silk can be used to great advantage. The needles and other
parts of the machine may be arranged to work either vertically as shown or
horizontally or in any other position if desired.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that I make no
claim to any of the parts separately which are well known and in common use but
what I claim is
1. The improved action arrangement and combination of the presser bar, point
or sinker bar, sley bar, and guide bars acting in conjunction with bearded needles
ubstantially as described and illustrated by the drawings annexed.
2. The improved arrangement and construction of the needle bar lever d
ubstantially as shown and described.
3. The improved general arrangement and construction of knitted warp
achinery where two or more guide bars are used substantially as described and
epresented in the Drawings annexed.
