PROVISIONAL SPECIFICATION.
Improvements in Looms for Weaving Two Separate Cloths, Wide
Cloth in Narrow Looms, Pillow Cloth, and Goods of a Tubular
Character in Textile Fabrios.
JOSEPH HENRY CUNLIFFE, of Bankside Mills, Rochdale, Cotton Manufacturer,
do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in looms, consisting of so constructing
the loom that two cloths can be woven at one and the same time, by putting a
pick of weft into both cloths at the same pick of the loom; to do this I form two
sheds, one above the other, of sufficient size to allow of the passage of a shuttle
through each, the upper shed being formed at an angle necessary for the safe
travelling of the shuttle, which travels through the shed along the warp threads
only, the lower shed for the under cloth is formed immediately beneath the upper
one, and at a lower level.
I have two shuttle boxes at each side of the loom, with suitable picking motions
to operate the shuttles, which can be picked so as to traverse in the same direction,
or in opposite directions, as may be desired.
Each cloth can be worked by separate healds, or by having two eyes or loops in
the healds at a distance corresponding to the two sheds; the same healds can be
made to operate for both cloths, the healds thus raising or depressing the ends in
each shed at the same time.
The warp for both cloths can either come from the same beam, or they can
each have a separate beam, but in either case the warp must pass over different
back rests which must be placed in suitable positions required for the correct
formation of the angle of the two sheds.
In weaving pillow cloth or other similar tubular fabrics, I have a few ends at
each side of the cloth operating through 'both sheds to connect the two cloths; by
having these connecting threads at one side only I weave a double width cloth in
a narrow loom.

Improvements in Looms for Weaving Two Separate Oloths, Wide
Cloth in Narrow Looms, Pillow Cloth, and Goods of a Tubular
Character in Textile Fabrics.
JOSEPH HENRY CUNLIFFE of Bankside Mills, Rochdale, in the County of
Laucaster, Cotton 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 :-
This invention relates to improvements in looms and consists in so constructing
the loom that two cloths can be woven at one and the same time by putting a pick

one above the other and each of sufficient size to allow a shuttle to pass through,.
the upper shed to be formed at an angle necessary for the safe passage of the
shuttle which travels through the shed along the warp threads only.
As in this upper shed the shuttle race is not of so firm a character consequent on
there being no slay board for the warp threads to rest upon I provide a substitute
by attaching in suitable position behind the slay-board and reed of loom a rod or
support which may be of any material providing it is of sufficient strength to
permit the warp threads to rest securely upon it and thus give a firmer shed for
the shuttle to travel through, this rod is always in position between the two warps
and in no way interferes with the shedding operations or with the satisfactory
working of the loom, but when a pillow cloth or other tubular fabric is being
woven this rod or support must not extend beyond or outside the warp in the reed,
so as to allow of the connecting threads hereafter referred to to operate freely
between the upper and lower shed, the lower shed for the under cloth is formed
immediately beneath the upper one and at a lower level.
I have two shuttle boxes at each side of the loom with suitable picking motions
to operate the shuttles, which can be picked so as to traverse in the same or in
opposite directions as may be preferred.
Each cloth may be worked by separate healds, or by having two loops or eyes
in the healds at a distance apart corresponding to the two sheds the same healds
can be made to operate for both cloths the healds thus raising or depressing the
ends in both sheds at the same time. I may say that I prefer separate healds for
then it is possible to adjust the sheds to a greater nicety.
The warp for both cloths can either come from the same beam or they can each
have a separate beam, in actual work I prefer the latter, but in either case the
warp must pass over different back rests which must be placed in suitable positions
required for the correct formation of the angle of the two sheds.
In weaving pillow cloth or other similar tubular fabrics I have a few connecting
threads at each side of the cloth operating through both sheds to attach the two
cloths together, by having connecting threads on one side only I weave a double
width cloth in a narrow loom.
There is not much need for drawings but in order that the more important parts
may be shewn the drawings herewith may be of service the same figures and letters
indicate corresponding parts wherever they occur.
Fig. 1. Sheet 1. shews a cross section of the two sheds as opened by the healds,
with slay board, rod or support behind the reed, back bearers and beain.
Fig. 2. Sheet 2. is a front view shewing the two shuttle boxes and shuttles
entering the two sheds, heald blocks and picking sticks.
A. (Fig. 1) is the slay board, B is the rod or support for the upper shed,
suitably attached behind slay board A, C is the upper shed, D the bottom shed.
1. 2. 3. 4 represent the healds for weaving a plain cloth, 1. 3 operating the upper
shed while 2. 4 operate the bottom shed. E is the back rest for the warp of the
top cloth, F the back rest for the warp of the under cloth G the warp beam.
L. M represent the blocks on heald rollers, and N the large block operating the
connecting threads. O is the picking stick of an ordinary overpick motion, P the
picking stick of an ordinary underpick motion.
H (Fig. 2) represents the top shuttle boxes. I the bottom shuttle boxes. J the
lower shuttle entering bottom shed D. K the top shuttle entering top shed C.
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. In looms for weaving two separate cloths at one and the same time, wide
cloth in narrow looms, pillow cloth and goods of a tubular character in textile
fabrics, in combination two shuttle boxes at each end of loom with suitable
underpick and overpick motions for operating two shuttles through two separate

page_text: sheds at one and the same time either in the same or in opposite directions, for
the purpose and in manner substantially as herein shewn and described.
2. In combination a rod or support of any material fixed in suitable position
behind alay board and reed of loom for the warp threads of the upper shed to-
rest upon, and thus give a firmer shed for the upper or top shuttle to travel
through, for the purpose and in manner substantially as herein shewn and.
described.
