ALONZO EARL WEMPLE, of the City and State of New York, United States of
America, but now of 8, Southampton Buildings, London. AN IMPROVED PROCESS
FOR THE PREPARATION OF MUSLIN AND OTHER LIKE MATERIALS FOR USE AS
WINDOW BLINDS AND FOR SIMILAR PURPOSES."
My Invention relates to an improved process of treating muslin and other like
fabrics or materials to render the same more suitable than the materials at present
used to serve as window blinds and for similar purposes.
The said Invention is carried into practise as follows, that is to say:-I first
stretch the muslin or other material by attaching it to a frame of any desired length
by means of fine glue, or by other suitable means. I then apply to the said muslin
or other material a size consisting of a solution of glue in water, to which is added
pyroligneous acid and crude glycerine. These ingredients are preferably used in
the following proportions, namely, 2 quarts of pyroligneous acid, 1 quart of crude
glycerine, 100 pounds of glue, and 30 gallons of water.
This size or solution may
be applied by means of a brush or otherwise to the muslin or other material.
The said muslin or other material, when dry, is subjected to treatment with a
mixture or compound of paint or coloring matter, and benzine or other suitable
solvent, whereby any desired color is given to the muslin or other material, and the
same is made either opaque or more or less transparent, as desired; and this
mixture or solution of the paint with benzine renders the said material or fabric
[Price & I

page_text: very soft and flexible. This mixture or solution is preferably applied by means of
a brush while the muslin or other fabric is stretched on the aforesaid frame.
The muslin or other fabric or material treated according to my Invention will be
greatly superior to other materials now used for roller blinds. It will roll and
unroll more easily and uniformly, will have a much better appearance, and will be 5
more durable and less liable to crack than such ordinary materials.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Alonzo Earl Wemple in the Great Seal Patent Office on the 9th March
1878.
ALONZO EARL WEMPLE, of the City and State of New York, United States of 1
America, but now of 8, Southampton Buildings, London. "AN IMPROVED PROCESS
FOR THE PREPARATION OF MUSLIN AND OTHER LIKE MATERIALS FOR USE AS
WINDOW BLINDS AND FOR SIMILAR PURPOSES."
My Invention relates to an improved process of treating muslin and other like
fabrics or materials to render the same more suitable than the materials at present 1
used to serve as window blinds and for similar purposes.
The said Invention is carried into practice as follows, that is to say:-I first
stretch the muslin or other material by attaching it to a frame of any desired length
by means of fine glue, or by other suitable means. I then apply to the said muslin
or other material a size consisting of a solution of glue in water, to which is added s
pyroligneous acid and crude glycerine. These ingredients are preferably used in
the following proportions, namely, 2 quarts of pyroligneous acid, 1 quart of crude
glycerine, 100 pounds of glue, and 30 gallons of water. This size or solution may
be applied by means of a brush or otherwise to the muslin or other material.
The said muslin or other material, when dry, is subjected to treatment with a
mixture or compound of paint or coloring matter, and benzine or other suitable
solvent, whereby any desired color is given to the muslin or other material, and the
same is made either opaque or more or less translucent, as desired; and this
mixture or solution of the paint with benzine renders the said material or fabric
very soft and flexible. This mixture or solution is preferably applied by means of
a brush while the muslin or other fabric is stretched in the aforesaid frame.
The muslin or other fabric or material treated according to my Invention will be
greatly superior to other materials now used for roller blinds. It will roll and
unroll more easily and uniformly, will have a much better appearance, and will be
more durable and less liable to crack than such ordinary materials.
Moreover, by the treatment of the muslin or other fabric as above mentioned I
form an opaque, semi-opaque, or translucent and very flexible fabric, on which
ornamental patterns or designs may be painted, stencilled, or impressed in gold,
silver, or any desired color on one side without running or striking through the
fabric, leaving the other side or surface free for independent ornamentation if
desirable. And the appearance of lace superposed on a plain or ornamented fabric
may thus be simulated with good effect on the said prepared fabrics or materials,

page_text: Having thus fully described the said Invention, and the manner of performing
the same, I wish it understood that I claim the above-described improved process
for the preparation or treatment of muslin or other like materials, for the purposes
set forth.
In witness whereof, I, the said Alonzo Earl Wemple, have hereunto set my
hand and seal, this Fifteenth day of February, in the year of our Lord One
thousand eight hundred and seventy-eight.
ALONZO EARL WEMPLE. (LS.)
