page_text: LETTERS PATENT to Léon Blazy, of the Firm L. Blazy Brothers, of Boulevard
de Strasbourg, No, 23, at Paris, Manufacturer, for the Invention of "AN
IMPROVED FABRIC OR CANVAS TISSUE."
Sealed the 17th September 1878, and dated the 20th July 1878.
COMPLETE SPECIFICATION filed by the said Léon Blazy at the Office of
the Commissioners of Patents on the 20th July 1878.
LEON BLAZY, of the Firm L. Blazy Brothers, of Boulevard de Strasbourg, No. 23,
at Paris, Manufacturer. "AN IMPROVED FABRIC OR CANVAS TISSUE."
The mounting of tapestry or work embroidered on canvas is attended with incon-
venience on account of the difficulty of sewing or uniting this work to the materials
or fabrics which are used with it, either for upholstery, or for church ornaments,
or other decorative purposes.
Now the present Invention consists of an improved canvas tissue or fabric, which
itself contains the stuffs or fabrics which are used with the embroidered or tapestry
work. All sewing is thus done away with, the bands or strips of the said stutis
or fabrics whether of silk, wool, or other material forming a body with the
canvas.
In order to manufacture the improved canvas tissue or fabric I employ the
ordinary processes of weaving. To the loom for making the canvas I fit the necessary
harness for the bands or strips of material to be formed on the canvas; these bands
may, for example, be produced by additional warps of red silk. These warps are
mounted on rollers or beams adjoining those of the cotton warp for the canvas;
they pass through healds which make the desired crossings. The mounting of these
healds will vary according to the pattern (arinure) chosen for the ground of the
silk or other material.
With the addition of a jacquard apparatus any desireable designs or ornaments
can be produced on this ground, in accordance with the decorative objects to be
afterwards embroidered on the remaining portions of the canvas.

page_text: The same cotton weft may connect the warps of the silk or other material for
making the bands or strips, and also form the canvas. This weft is concealed by
the warps of the material of the bands.
I can also produce transverse bands or strips of the silk or other material in the
weft instead of those produced longitudinally in the warp. In this case the cotton
warp extends the whole breadth of the piece, and it is the weft which varies. I
throw alternately a series of cotton wefts which will produce the ordinary canvas,
then a series of close wefts, of silk or other material, which will produce the bands
or strips.
Again, I can, with the aid of espalier battens (battants á espaliers), produce in
other ways the full parts of silk or other material in the canvas, or these parts can
be produced in velvet.
The canvas tissue or fabric made according to my Invention has simply to
receive the tapestry or embroidery work in the canvas portions, as it contains the
bands or strips of silk or other material which complete it, and allow of its being
employed without any piece being added thereto for upholstery and other decorative
purposes.
And having now described the nature of my said Invention, and in what manner
the same is to be performed, I declare that I claim, the improved fabric or canvas
tissue manufactured in one piece, substantially as herein-before described, and
containing canvas parts and parts of silk or other material, as herein-before
explained.
In witness whereof, I, the said Léon Blazy, have hereunto set my hand and
seal, this Sixteenth day of July, One thousand eight hundred and seventy-
Witness,
