Improvements in Means for Producing Sectional Warps.
I BERNHARD COHNEN of the firm of Cohnen & Neuliaus of Grevenbroich,
Rhenish Prussia in the Empire of Germany Manufacturers do hereby declare the
nature of this invention to be as follows:-
My said invention relates to means for building and placing in situ sectional warps
in a much more expeditious and economical manner than heretofore.
According to my invention I provide a series of cylinders rings or tubes made of
paper of one two or more thicknesses or of any suitable material or compound such
as wood, papier maché metal, vulcanite or the like the interiors of the cylinders
tubes or rings fitting the warping beam or a rod or spindle taking the place of
the warping beam. A sliding key of square or other section extends along the
warp beam rod or spindle and passes through or is held by the usual end flanges
of the warp beam.
A slot is formed in the interior of each of the said cylinders tubes or rings to fit
the key so that when the cylinders are strung on the warp beam or rod the key
passes through the slot in each cylinder and the whole series of cylinders are thus
secured to the warp beam or rod.
Previously to being thus strung upon the warp beam or rod the said cylinders or
tubes are wound with a suitable supply of warp of the requisite sectional colour or
count as is well understood. The cylinders or tubes are provided with loops tags
or attachments by which to secure the warp ends before commencing to wind on
and I also form the cylinders or tubes with holes or depressions to receive the knots
formed by the attachment of the warp ends to the loops. When the cylinders or
tubes have had the requisite quantity of yarn wound upon them they are successively
placed in the requisite order upon the warp beam or rod, one of the end flanges
being removed. As each cylinder strung on the key is passed through the slot to
secure the cylinder to the beam or rod. When the beam or rod is full the outer
end flange is added and the whole is secured together and between the two end
flanges by any suitable means. I do not confine myself to securing the cylinders.to
the beam or rod by a key as described as I might use other means. For example I
might make the warp beam or rod square and square the interiors of the cylinders
or I might make the beam or rod retractable and expand it when the cylinders had
been strung on so as to secure and hold the cylinders or tubes in position.

Improvements in Means for Producing Sectional Warps.
BERNHARD COHNEN of the firm of Cohnen & Neuhaus of Grevenbroich,
Rhenish Prussia, in the Empire of Germany Manufacturers 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
and accompanying drawings:-
My said invention relates to means for building and placing in situ sectional warps
in a much more expeditious and economical manner than heretofore.
According to my invention I provide a series of cylinders rings or tubes made of
paper of one two or more thicknesses or of any suitable-material or compound such
as wood, papier maché, metal, vulennite or the-like, the interiors of the cylinders,
tubes or rings fitting the warping beam or a rod or spindle taking the place of the
warping beam. A sliding key of square or other section extends along the warp
beam, rod or spindle and passes through or is held by the usual end flanges of the
warp beam.
A slot is formed in the interior of each of the said cylinders, tubes or rings to fit
the key so that when the cylinders are strung on the warp beam or rod the key
passes through the slot in each cylinder and the whole series of cylinders are thus
secured to the warp beam or rod.
Previously to being thus strung upon the warp beam or rod the said cylinders or
tubes are wound with a suitable, supply of warp of the requisite sectional colour
or count as is well understood: The cylinders or tubes. are provided with loops,
tags or attachments by which to secure the warp ends before commencing to wind
on and I also form the cylinders or tubes with holes or depressions to, receive the
knots formed by the attachment of the warp ends to the loops. When the cylinders
or tubes, have had the requisite quantity of yarn wound upon them they are
successively placed in the requisite order upon tlie warp beam or rod one of the end
flanges being removed: As each cylinder is strung on the key is passed through
the slot to secure the cylinder to the beam or rod. When the beain or rod is full
the outer end flange is added and the whole is secured together and between the
two end flanges by any suitable means. I do not confine myself to securing the
cylinders to the beam or rod, by a key as described as I might use other means.
For example might make the warp beam or rod square and square the interiors
of the cylinders or might make the beam or rod retractable, and expand it when
the cylinders have been strung on so as to secure and hold the cylinders or tubes
in position.
To render my invention perfectly clear I will now proceed to describe the
same with reference to the annexed' sheet of drawings which illustrate specific
means whereby my said invention may be carried into practical effect.
Fig. 1 is a separate perspective view of a ring or cylinder a upon which I
wind warp-yarn as hereafter described:
b
Fig. 2 is a sectional view of the ring, a showing a portion of warp 6 wound on.
Fig 3 is a longitudinal; sectional view of a sectional warp built up upon my
improved principle.
Fig. 4 is a cross section of Fig. 3 at the line A B Fig. 3:
Fig. 5 is a longitudinal section of a portion ofra sectional warp mounted upon
a wooden beam instead of upon a metal tube as in Fig. 3.
-
The improved ring, a consists, as, clearly shown in Figs. 1 and 2 of a hollow
cylinder which may be composed as set forth in my Provisional Specification
of one, two or more thicknesses of paper cemented together or of any other
suitable material or compound such as wood, papier maché, metal, vulcanite-or
the like The internal diameter of the rings a is such as to fit upon a tube as
shown in Fig. 3 or on a wooden beam as in Fig. 5 or on any other body

page_text: which may be designed to carry the warp. A tag or loop is attached to the
ring a as a means of attachment for the warp ends.
In order to sink the knot beneath the level of the circumference of the
ring I form a hole or depression d in the circumference opposite to the place
where the knot comes when the winding on of the warp is commenced.
Thus
there is no excrescence or lump to destroy the regularity of the wound on.
warp.
In Fig. 2 show the knot lying in the hole d the warp b being smoothly
wound over it. I also form a key way e in the interior of the ring as clearly
seen in Figs. 1 and 2. I will now show how these rings a with the wound on.
yarn are applied and placed together and built up into a sectional warp.
The warp is wound upon the rings in any suitable manner as will be well
understood.
g
Referring to Fig. 3 I provide a metal tube which fits the interior of the rings..
Upon this tube I cut a key-way of the same size as the key-way e in the rings..
I also provide a key sufficiently long to pass through all of the rings on the tube
I also provide two end flanges h h also fitting the tube the key y passing-
through the flanges also. First of all I secure the end flange h upon the tube by
means of set screws and then string the rings full of warp viz. 1, 2, 3, 4, 5, or
any greater or less number upon the tube successively. As the stringing on
proceeds I push the key g through from one ring to the other until the last ring is.
reached or I may push the key through after all of the rings have been placed on..
I then place the other flange on the other end of the tube. To press all of the
rings closely together I pass a bolt through the tube f the end of the bolt being
screwed and provided with a nut as shown and the head of the bolt resting
against the end of the tube. Removing the nut k¹ I place a hollow cap m over
the bolt the foot of the cap resting against the flange as shown in Fig. 4.
then apply the nut and screw it up against the cap m thus causing the cap m to
press the flange against the rings and warp and thus compress the rings and warp
between the end flanges h h. When sufficiently compressed the flange h' may be
secured to the tube by set screws so that the flanges are maintained permanently
in their proper positions. I may now remove the bolt k and cap m leaving the
built up sectional warp to be placed in the loom.
I
The projecting ends of the tube may either be dropped into bearings or
journals may be applied to the ends of the tube or the sectional warp may be
mounted in any desired manner. In Fig. 5 I show the sectional warp mounted on
an ordinary wooden beam n. As the application of the compressing bolt and cap
is not possible in this case, I mount and secure a disc or carrier o on the end of
the beain the said disc or carrier o having two or any suitable number of screws p.
The inner ends of these screws bear against the end flange and by turning
the screws the flange h¹ can be pushed forward so as to compress the rings and
warp after which the flange ¹ can be secured in position as before by the set
screws and the screw carrier o removed.
A key is employed to secure the rings a to the beam n in the same manner as
the key g is employed to secure the rings to the tube in Figs. 3 and 4. [t
will be easily understood that under my improved method sectional warps can
be easily formed and built up or modified. The rings a may be of any size and
length and they might be secured to the tube for to the wooden beam n or
upon any other suitable supporting centre by means other than a key as
described. For example I might make the warp beam or rod or tube square
and square the interior of the cylinders or I might make the beam, tube or
rod to expand and thus grip the rings a.
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 what I
claim is :-
As means employed in the production of sectional warps the rings or

page_text: hollow cylinders a composed of one or more thicknesses of paper, cemented
together or of papier maché, wood, metal, vulcanite, or other suitable material or
compound and having loops or tags for the attachments of the ends and
holes or depressions to receive the attachment knots the said rings or cylinders
being adapted to be mounted upon tubes, beams, rods or other axes and secured
thereto by keys or other suitable means for the purposes and substantially' as
described and shown.
2. The improved method of and means for producing a sectional warp by
placing rings or cylinders a with yurn-wound thereon-successively upon a tube or
beam and compressing and binding the whole together--between end flanges by
means of a bolt and cup as shown in Fig. 3 or by serews passing through a
dise or carrier as shown in Fig. 5 of the drawings and substantially as described.
