Improvements in or connected with Loom Warp Beams.
I, THOMAS WRIGLEY of Waterside House, Todmorden in the County of York,
Mill Manager, do hereby declare the nature of this invention to be as follows:-
This invention relates to looms for weaving in which two or more warps are
required to be woven together and consists in improvements in the construction of
the beams on which the warps, which may be of any kind of yarn, are wound and
means for putting said beams together so as to form one beam ready for mounting
on the loom. It is well known that in looms where it is desired to weave off two
or more beams of warp together, there has hitherto been great difficulty in keeping
the tension on each beam equal so that the warps are unwound in equal lengths
from each beam, various devices resorted to for producing this effect not having
given satisfactory results. The object of my improvements is to overcome this
difficulty, which I effect in the following manner :
I form a tube or shaft of metal with one or more longitudinal grooves in its
outer surface, the tube or shaft being supported on the loom in suitable brackets.
I form the beams of tubes with flanges, the tubular part of each beam being of
such diameter that it fits on the grooved tube or shaft. Said tubular part is
formed with one or more longitudinal grooves pressed into it corresponding with
the grooves in the tube or shaft, the inward projections of the grooves of the
beams forming feathers or keys fitting into the grooves of the tube or shaft and
securing the beams to the tube or shaft in the circumferential direction. Upon
the ends of the tube or shaft I place the usual ruffles or friction pulleys, one of
which may be fixed thereto by set screws or otherwise, while the other is arranged
so that it can slide longitudinally and be tightened against the ends of the beams
inserted between it and the fixed ruffle. The tightening may be effected by any
ordinarily used suitable means for such purposes, for instance by means of a nut
screwed upon a threaded part of the inner shaft or tube. By preference however
when using a tube on which to mount the beams I fix inside the tube a casting or
its equivalent tapped for a screw and pass a cottar through the sliding ruffle and
slots in the tube, and draw the ruffle up by means of a screw passing through and
formed with a collar bearing against said cottar and screwed into said casting.
The ruffles and outside ends of the yarn beams may be formed so as to interlock
into each other in order further to assure their simultaneous rotation.

I, THOMAS WRIGLEY, of Waterside House, Todmorden in the County of York,
Mill Manager, 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 looms for weaving in which two or more beams of
warps are to be woven off together and consists in improvements in the construction
of the beams on which the warps, which may be of any kind of yarn, are wound
and means for putting said beams together so as to form one beam ready for
mounting on the loom.
It is well known that in looms where it is desired to weave off two or more
beams of warp together, there has hitherto been great difficulty in keeping the
tension on each beam equal so that the warps are unwound in equal lengths from
each beam, various devices resorted to for producing this effect not having given
satisfactory results. In wide looms also when the warp is wound on one beam, the
deflection or springing of the beam produces an unequal tension of the yarn at
different parts of the beam while wound on and woven off, which results in an
imperfectly woven cloth and more frequent breakages of the warp threads. The
object of my invention is to overcome these difficulties, which I effect by placing
two or more tubular warp beams and a pair of ruffles upon a preferably tubular
shaft with the flanges of the beams abutting against each other and held in close
contact, said beams, ruffles and shaft being further provided with devices for
assuring the simultaneous rotation of the beams and ruffles.
On the drawings appended hereunto :--
Figs. 1 and 2 shew vertical and horizontal sections of the shaft and beam end;
Figs. 3 and 4 cross sections along lines A B and C D of Figs. 1 and 2;
Fig. 5 a shaft and two beams put together;
Fig. 6 a partial section of a shaft and two beams secured by a modified
arrangement;
Fig. 7 another modification;
Fig. 8 a cross section of the same.
In carrying out my invention I preferably use a hollow or tubular shaft a
formed with a longitudinal groove a¹ or more grooves thau one, in its outer surface,
which after the beams are mounted thereon is placed into suitable brackets on the
loom and forms the pivots of the composite beam. I form each beam of a tube b
and flange formed with bosses 2 inserted into the tube and of such size that
they fit easily ou the shaft a. The tube may have a groove or grooves pressed
into it corresponding with the groove or grooves in the shaft the inward projections
of the grooves of the beam forming feathers or keys fitting into the grooves of the
tubular shaft a and securing the beams thereto in the circumferential direction.
Or instead thereof the flanges b¹ may be formed with projections or feathers 6³ as
shown and serving for the same purpose. Upon the ends of the shaft a I place the
ruffles or friction pulleys c one of which may be fixed to the shaft by set screws or
otherwise, while the other is arranged so that it can slide longitudinally and be
tightened against the end of the beam so as to hold the beams firmly between it
and the fixed ruffle. The tightening may be effected by any ordinarily used
suitable means for such purpose.
On the drawings two arrangements for tightening or drawing up the ruffle are
shewn. In Figs. 1 to 4 the ruffle c is shown drawn up against the beam flange by
means of a screw d which is screwed into a nut e fixed in the shaft a and has a
collar d' formed on it which bears against a cottar ƒ passed through a slot in the

page_text: ruffle and shaft. Fig. 6 shows another arrangement. Two or more L bolts g are-
inserted into corresponding recesses and holes in the ruffle and slots in tubular
shaft a and the beams pressed together between the ruffles by tightening up the
nuts on these bolts. As stated, one of the ruffles may be fixed on the shaft and the
other provided with a tightening arrangement or both may be thus provided.
The ruffles may be formed with projections c' Fig. 6 or their equivalents fitting
into corresponding recesses or slots in the beam flanges b', or the flanges formed
with projections or their equivalents fitting into recesses of the ruffles as shewn by
Fig. 7. Where this arrangement is used the groove in the shaft a and feathers or
keys on the beam or beam flanges may be omitted as the heads of the bolts in
the arrangement Fig. 6 fitting into the slots of the shaft a act as keys or drivers
and cause the ruffles and consequently the beam interlocked with them to rotate.
simultaneously with the shaft, while with the arrangement shewn by Figs. 1 to 4
the cottarf fitting at one end f¹ into a slot in the shaft answers the same purpose.
The arrangements or devices for tightening up the ruffles or fixing the beams on
the shaft so as to rotate with it may be dispensed with where such interlocking
arrangements of ruffles and beams are applied, and the beams and ruffles pushed
close up together by hand and held in position by a loose split collar / fixed by a
tightening screw as shewn by Fig. 7 or by equivalent means, in which case the
beams and ruffles may turn on the shaft. Obviously one ruffle may be cast in one-
with each beam and the beams pushed up close together and held in position on the
shaft by set hoops or fixed by other means as hereinbefore described. The
intermediate flanges abutting on each other may be formed with recesses and
projections interlocking with each other as shewn on Fig. 6 so as further to assure
the simultaneous rotation and drawing off of the warps, more particularly when,
the ruffles and beams are not fixed to the shaft, but can turn on it.
A solid shaft may be used and the parts held together by means of a collar at
one end and a nut screwed upon the shaft at the other end, keys or feathers or
equivalent means being used to assure the simultaneous rotation of the beams,.
ruffles and shaft. 1 do not confine myself to the mechanical arrangements shewn,
but these may be replaced by equivalent arrangements.
By arranging and combining two or more warp beams and a shaft in the
manner hereinbefore described with their intermediate flanges in contact a
combined beam of great stiffness is formed, as the middle flanges of two beams
held closely together form a stiffener for the shaft and prevent its springing and
bending, and the regular and uniform drawing off of the warps from the several
beams combined into one and equal tension of the warps in the loom is assured,
while for beaming and sizing the warps for wide looms, machines of ordinary
narrow width can be used.
I am aware that tubular beams with and without grooves or feathers formed on
them have been used before for other purposes and I do not claim the construction
of such beams.
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
1. The arrangement of two or more tubular loom warp beams upon a shaft with
their intermediate flanges in contact and between two ruffles in combination with
devices or means for locking said beams and ruffles on or to the shaft substantially
as and for the purpose set forth.
2. The arrangement of two or more tubular warp beams on a shaft with their
intermediate flanges in contact with each other in combination with devices for
retaining said beams on the shaft with said flanges in contact, substantially as
herein before described and for the purpose set forth.
3. The combination of a tubular shaft with two or more tubular warp beams
and a pair of ruffles and devices for drawing said beams and ruffles tightly together
and rotating them and the shaft simultaneously substantially as and for the purpose
set forth.

page_text: 4. The combination of a tubular shaft formed with one or more longitudinal
grooves therein, two or more tubular warp beams formed with corresponding keys
or feathers, a pair of ruffles with feathers fitting said groove or grooves and means
for drawing up one or both of said ruffles on the shaft substantially as hereinbefore
described and illustrated by the drawings.
5. The combination of a tubular shaft, tubular warp beams, ruffles, nut, screw
and cottar substantially as hereinbefore described with reference to Figures 1 to 5
of the drawings.
6. In loom warp beams the use and formation of separate ruffles with projections
or their equivalents fitting into recesses of the warp beam flanges, or of said flanges
with projections or their equivalents fitting into recesses of the ruffles, substantially
as hereinbefore described and illustrated by the drawings.
