PROVISIONAL SPECIFICATION left by the said Léopold D'Aubréville at
the Office of the Commissioners of Patents, with his Petition, on the
22nd December 1865.
I, LEOPOLD D'AUBRÉVILLE, of No. 60, Boulevart de Strasbourg, Paris, in
the Empire of France, Civil Engineer, do hereby declare the nature of the said
Invention for "AN IMPROVED METHOD OF AND APPARATUS FOR SIMULTANEOUSLY
MANUFACTURING.: OR WEAVING TWO SEPARATE CLOTHS AT ONE AND THE
OPERATION ON A COMMON HAND OR POWER LOOM SLIGHTLY MODIFIED. FOR THE
PURPOSE," (a communication to me by Gerber-Ulrich, a person. resident at
Sainte Marie-aux-Mines, a Town of France), to be as follows:-
This Invention consists in simultaneously weaving two separate.cloths. or
fabrics of any kind on a common hand or power loom, the two cloths -being

page_text: woven above one another, and a single batten being used, fitted with a single
reed divided lengthways in two parts, and also a single harness for both
warps, the heald thereof being furnished with two rows of stitches or eyelets
for working the warps. There are of course two shuttles plying above one
another betwixt their respective warps, the said shuttles being actuated as
usual. There are also two rollers for each fabric, the one for the warp the
other for the woven cloth to be enrolled thereon.
On the accompanying Sheet of Drawing, forming part of this my Pro-
visional Specification, a, b, indicates the cross piece which divides the reed
in two parts, and B the shuttle boxes.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Léopold D'Aubréville in the Great Seal Patent Office on the
21st June 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, LÉOPOLD
D'AUBREVILLE, of No. 60, Boulevart de Strasbourg, Paris, in the Empire of
France, Civil Engineer, send greeting.
WHEREAS Her most Excellent. Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of December, in the year of our
Lord One thousand eight hundred and sixty-five, in the twenty-ninth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Léopold D'Aubréville, Her special licence that .I, the said
Léopold D'Aubréville, my executors, administrators, and assigns, or such
others as I, the said Léopold D'Aubréville, my executors, administrators,
and assigns, should at any time agree with, and no others, from time to time
and at all times thereafter during the term therein expressed, should and
lawfully might make, use, exercise, and vend, within the United Kingdom of
Great Britain and Ireland, the Channel Islands, and Isle of Man, an Inven-
tion for "AN IMPROVED METHOD OF AND APPARATUS FOR SIMULTANEOUSLY MANU-
FACTURING OR WEAVING TWO SEPARATE CLOTHS AT ONE AND THE SAME OPERATION
ONCOMMON HAND OR POWER LOOM SLIGHTLY MODIFIED FOR THE PURPOSE," (a
communication to me by Gerber-Ulrich, a person resident at Sainte Marie-
aux-Mines, a Town of France), upon the condition (amongst others) that I,
the said Léopold D'Aubréville, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seals, should
-particularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same to be filed in

page_text: removed and it is brought back again as soon as the thread is mended or
tied ("rattaché"). Each string, riband, or heald of the harness, instead of
having a single stitch or eyelet is provided with two, the distance betwixt
them is proportionate to the pass; the threads of the upper warp are
alternately running through the eyelets of the upper row, and the threads of
the lower warp run alternately through the lower eyelets. As it frequently
happens that the shuttles are held fast within the warp, and as a certain
exertion or force is required to drive back the reid, the threads are frequently
broken, or in this place remain slacker than in the other parts of the warp,
which causes irregular or defective places; with the-disposition of the shuttle
boxes which are applied to this improved loom, such defects will no longer
occur, for as soon as one of the shuttles does not reach clear to the bottom of
the box into which it is driven, even if the other shuttle were to be driven
to its place, the loom will stop.
:
i
The weft fork ("casse-trame") works as well with this loom as 'with a
single loom; as soon as the weft fails either to the upper or lower shuttle the
loom stops directly.
The first woven cloth rolls itself up a little higher up than the reed, whilst
the second one rolls itself up as usual, such space is left betwixt both pieces
as is sufficient to allow the weaver to easily overlook both pieces, and he can
readily unweave any of them when he perceives any defect; for the lower one
he is not obliged to pass his fingers through the threads of the upper warp, he
need only to pass his hands betwixt the two pieces and to unweave as for the
upper piece; then by applying a double regulator, one for each piece, instead
of throwing away each time the same length of defective stuff or waste in each
piece, he leaves without touching the one which is defectless, unweaving only
the one in which there was imperfection.
All accessory organs or contrivances applied to common hand or power
looms may be applied to this one, in order to complete an easy and regular
weaving, such as regulator, weft-fork, stretcher, and, all, other usual additional
organs or parts of looms used for the better work. In fact, all such accessory
organs have been added to the looms already built according to the system
just described.

of the loom; Figure 2 is a front view of the left part of it; Figure 3, a

NOW KNOW YE, that I, the said Léopold D'Aubréville, do hereby declare
the nature of the said Invention, and in what manner the same is to be.
performed, to be particularly described and ascertained in and by the following
statement:-
In all looms every thread of the warp must run through the teeth of the
reed, whatever may be the kind of tissue to be woven, and the teeth of the.
reed after each throw of the shuttle bring close the thread of the weft by
the working of the batten.
Now in the improved loom of the Invention communicated to me, which
loom is partly represented on the annexed Sheet of Drawing, to the scale
of the main piece or organ, without which it could not be possible to
attain the desired result is the "reed," which as in every kind of loom is
carried by the batten. The reed of this improved loom is twice as high
as in other looms, and it is divided lengthways in two parts in its middle;
through the upper part runs the warp of one piece of cloth, and through the
lower part runs the warp of another piece, both cloths are similar for the
work; but they can be of different shades or colours. Both are woven
simultaneously by means of "a single batten, a single reed,, and a single
harness," each drifting ribbon or heald of the warp thereof being furnished with
two rows of stitches or eyelets for working the warps. Instead of having both
warps rolled up on the same roller and of causing both the woven cloths to
enroll themselves also on a same roller the warps are enrolled each one apart
on a special roller, both the said rollers are placed behind the loom, the threads
of each warp run then separately on a warp holder, the one of the lower warp
is of a cylindrical shape, and the one of the upper warp is composed of a rod
carried by two stands capable of hinging on the shaft of the former one, the
latter warp holder remains at its upper position as the loom is working so as to
have the two warps held apart from one another and the upper pass ("la foule
du haut") is as well formed as the lower one which could not be if the edge of
this warp holder was bought at its lower horizontal position when weaving. It is
brought to the horizontal position only when a thread of the lower or under
warp is broken, this warp being no longer so stretched helps to find out, the
broken thread, which can be easily brought out and mended, and this. prevents
the breaking of many other threads, which without this precaution might
be broken out. The position of this warp holder is. regulated by means
of a treadle situated in the middle of the loom; when the latter is working
the treadle is held by a stop, and whenever a thread is broken the treadle is

page_text: another side view, shewing the upper holder brought in the horizontal or
lower position for finding out and mending a broken thread.
It would be useless to describe all the pieces of the loom, which are the
same as in common power looms, all of them are carried by a cast-iron
frame B as usual. The batten C is provided with a double reed D; on each
side of the loom there is a double shuttle box E, each part thereof corre
sponding to a respective part of the reed; and shuttle drivers I, J, playing in
each part of the box E, throw forth both shuttles at once, which bring their
weft threads betwixt their respective warps, the upper warp W proceeding
from the roller K, and the lower one W₁ from the roller L; the upper woven
cloth is enrolled on the roller M, and the lower cloth around the roller N,
both of the said rollers being provided with regulators as usual; V,V' indicat
the warp holders.
and
y be
The Invention communicated to me being now sufficiently descri
illustrated on the annexed Sheet of Drawing, I declare that whates
the modifications brought into the shape and arrangement of the several
pieces composing a loom, I claim the exclusive right of simultaneously
manufacturing or weaving two separate cloths or fabrics at one and the same
operation on a common hand or power loom, by means of a single batten
fitted with a single reed divided lengthways in two parts; and also a single
harness for working both warps, the strings or healds of which being furnished
with two rows of stitches or eyelets for working their respective warps,
through which play two shuttles, thrown by two shuttle drivers running
at once in a double shuttle box, the whole Invention being substantially
set forth in the foregoing description, and partly shewn on the annexed
Sheet of Drawing.
In witness whereof, I, the said Léopold D'Aubréville, have hereunto se
my hand and seal, this Twelfth day of June, in the year of our Lord
One thousand eight hundred and sixty-six.
Witness,
V. HANDEVILLE.
