Improvements relating to Sectional Warping.
I, REGINALD HADDAN of the firm of Herbert & Co. Patent Agents of
18 Buckingham Street Strand W.C. London Civil Engineer do hereby declare
the nature of this invention a communication to me from abroad by Jules Gratry
of Halluin in the Republic of France, Weaver and in what manner the same is
to be performed to be particularly described and ascertained in and by the following
statement:-
The object of this invention is to do away with the circular flanges or discs at
present provided on the sections of a sectional warping machine, so that the
sections may be transferred direct from the warping machine onto the warp beam.
The annexed sheet of drawings illustrates the improvements in the machinery to
effect this result.
Fig. 1 is a side elevation and Fig. 2 a front elevation of the flanged drum F C F
formerly used for receiving the yarns.
Fig. 3 is a longitudinal section and Fig. 4 an end elevation of a drum S to be
used in place of the said flanged drum F C F.
Fig. 3 is a sectional view of an extensible or telescopic sleeve S¹ to be placed
over said drum S.
Fig. 6 is a view of an improved warp beam.
Fig. 7 an end view thereof.
No alteration is made in the warping machine itself, the arbor on which the
sections FCF are mounted is employed in this invention with its continuous
feather or key, but in place of using a flanged drum F C F a plain or unflanged
drum S is threaded on the said shaft, this drum having the length required for the
section. The drum carries a covering sleeve or mantle S₁ fitting sufficiently
accurately thereon to slide with a little friction, this mantle being comparatively
thin in substance and intended to receive the yarns. The ends of the yarns are
united in a knot and are fastened in place by inserting this knot in a cavity R' in
the drum S the yarns passing through a slit C in the drum S and a slit C in the
edge of the covering mantle S¹. The two end plates such as P in the drawings
movable on the shaft of the warping machine are then brought up close to the
ends of the drum or of the sleeve on the drum and fixed in place on the shaft.
The yarns are then wound on the mantle until it is sufficiently charged when the
end plates or one of them is removed and the mantle with the warp on it is removed
leaving the drum S on the shaft. The section of warp is then threaded on the
shaft of the warp beam A and a new section is wound in the same way on the same
drum S with the same mantle or on a new drum with mantle of different length.
This second section is then slid onto the warp beam alongside of the first and the
same operations are continued until the warp beam is fully charged.
The warp beam is that used in nearly all looms now in use, that is to say it is a
hollow metallic shaft. Before threading the sections on this shaft the knot which
unites the ends of the yarns of each section must be fixed in place on the shaft.
According to the present invention the shaft A is made with a longitudinal
continuous slit R and at one end of this slit is an enlarged hole O of sufficient size
to allow the knot to pass through so that it may be slid along under the slit R
and be held fixed by the edges of the slit which is too narrow to allow the knot to
pass through.
To permit of the adjustment of the end plates P, these plates or circular discs
slide freely on the shaft, on each plate is a semicircular plate m having on its inner
edge a semi-annular flange with lugs forming a corresponding part to a semi-
annular flange with lugs on the plate P itself. By securing the lugs together by

page_text: bolts and nuts bb or other suitable fastenings the shaft is firmly gripped between
the flanges and the plate is fixed in the position it occupies when the bolts are
screwed tight. To move the plate. P. the bolts: b bare sufficiently, loosened to
release the grip on the shaft.
Since sections are very variable as regards their length according to the stuff
and material to be woven; it would be necessary, with this system to have a large
number of mantles S¹ of different lengths, which would be costly and require large
storage space, to obviate the necessity of having a large number of mantles, a
mantle as shown in Fig. 5 may be used made of very thin metal and telescopically
extensible the one part or parts S2 sliding within the other S' and made extensible
in any suitable way or by any means as employed in analogous cases. It is not
essential that the mantle shall be very thin. It is unnecessary to provide for the
extension of the drum or core S since it serves only to support the mantle S' and
may be of less length than the mantle or made up of two or more pieces.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed. I declare that what I
claim is
1. For employment in sectional warping a system of drums S with mantles S¹
without fixed flanges so that each section when wound as set forth may be
transferred direct onto the warp beam of the loom.
2. The combination with a warping machine shaft of a drum or drums S, a
sleeve S' on said drum without fixed flanges thereon and movable end plates for
sectional warping as set forth.
3. The combination on a warping machine shaft, of a drum S, an extensible
sleeve S' on said drum without flanges thereon, and end plates on said shaft one or
both of which movable for the purpose set forth.
4. A warp beam having one or both end plates removable and adjustable
along the beam, and a slot R with knot passage hole o in said beam for the
purpose set forth.
