& Co., Patent Agents, Southampton Buildings, London, for the Invention of
"AN IMPROVED METHOD OF WEAVING, APPLICABLE FOR THE PRODUCTION OF
FABRICS OF DOUBLE WIDTH, AND FOR THE MANUFACTURE OF BAGS AND
SIMILAR ARTICLES WITHOUT SEWING." A communication from abroad by
Louis Jules Nestor Rousseau, of Lyons, France.

WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
"AN IMPROVED METHOD OF WEAVING, APPLI-
Southampton Buildings, London.
CABLE FOR THE PRODUCTION OF FABRICS OF DOUBLE WIDTH, AND FOR THE
MANUFACTURE OF BAGS AND SIMILAR ARTICLES WITHOUT SEWING." [A com-
nunication from abroad by Louis Jules Nestor Rousseau, of Lyons, France.]
The principle of this Invention consists in superposing two fabrics, both of which
may be alike or different, whose threads, whether similar or otherwise, are passed
into the same reed and woven alternately with one or more shuttles.
I obtain a double width by making one insertion for the upper fabric, two
insertions for the lower fabric, and one insertion for the upper fabric. The union
of the two fabrics is effected (with the weft threads crossed or not crossed) at the
right or left hand, perpendicularly to the reed and consequently in the direction of
the warp; thus all kinds of material may be woven.
In producing woven cases or bags according to this Invention the two fabrics are
united by means of a taffeta or other loom. The uniting may be effected according
to circumstances in a straight line, or curved, or folded. By thus uniting the
fabric in a straight line, then making the double width, and then uniting again,
a perfect bag is produced without sewing.
The said Invention may be applied to all existing looms without any expense
other than that required for the adaptation, and which is very small. It is
applicable to all materials capable of being woven or plaited.

WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "AN IMPROVED METHOD OF WEAVING, APPLI-
CABLE FOR THE PRODUCTION OF FABRICS OF DOUBLE WIDTH, AND FOR THE
MANUFACTURE OF BAGS AND SIMILAR ARTICLES WITHOUT SEWING." A com-
munication from abroad by Louis Jules Nestor Rousseau, of Lyons, France.
When it is desired to weave fabrics of greater width than the size of a loom will
permit it has been usual to weave two superposed fabrics and afterward unite the
same by a seam. This Invention however is designed to dispense with such seam,
and has for its object the production of two superposed fabrics, which are united
upon the loom instead of by a seam, as above set forth. These fabrics may be alike
or different, their threads, whether similar or otherwise, being passed into the same
reed and alternately woven with one or more shuttles.
The double width is obtained by making one insertion for the upper fabric, two
insertions for the lower fabric, and one insertion for the upper fabric, that is to say,
in the weaving there will be two insertions one after the other for each fabric.
The union of the two fabrics is effected (whether two wefts are to be crossed or
not) at the right or left hand, perpendicularly to the reed, and consequently in the
direction of the warp; all kinds of material may thus be woven. The crossing of
the wefts is effected when a fabric of several colors is being woven and it is
desired that the weft should correspond in color with the warp.
In forming woven cases or bags and similar articles according to this Invention
the two fabrics are united or connected by the same loom on which such fabrics are
formed, and I employ the class of loom most suitable for the article to be produced.
This junction or union may be effected, according to circumstances, in a straight,
curved, or irregular line. By effecting the union at the part where the two fabrics
meet in a straight line, then making the double width, and afterwards another
union of the fabrics, I am enabled to produce a perfect case or bag without seam or
sewing.
The said Invention may be practised upon all existing looms without any
additional expense beyond that incurred in the adaptation, and which is very small,
and the said Invention is applicable to all materials capable of being woven or
plaited.
Having thus fully described the said Invention as communicated to me by my
foreign correspondent, and the manner of performing the same, I wish it understood
that I claim,
The method of weaving and uniting two superposed fabrics upon a loom, as above
set forth and for the purposes specified.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Tweny-fourth day of April, in the year of our Lord
One thousand eight hundred and eighty.
