PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Parchment Fabric.
I, LOUIS FERDINAND DOBLER of 95 Boulevard Beaumarchais, Paris, France,
Engineer, do hereby declare the nature of this invention to be as follows :—
The object of this invention is to obtain parchment fabric designed to replace paper
in its various applications, such as for prints of any kind, drawings, water-colour and
other paintings, heliographs, photographs, hook-binding, envelopes, and the like.
The improved parchment fabric is designed to be used in lieu of paper in all cases
where it is desired to combine with the qualities and properties of paper great
strength.
The general mode of manufacturing the said parchment fabric consists in covering
any suitable fabric with a layer of paper or other similar material either in the state
of paste or in the form of a sheet. This layer is applied to one side or to both sides
of the fabric, and is caused to adhere thereto by a size which is insoluble in water.
such as described in the specification of Letters Patent No. 9949 dated July 15th 1887,
granted to L. F. Dobler and E. A. Sengel.
The improved parchment fabric thus prepared, besides having the strength due to
the fabric which is employed in its manufacture presents all the qualities of the paper
used for the applications which I have above enumerated. Moreover, the size which
is employed, being quite insoluble, ensures the perfect adherence of the paste and
fabric, even when the parchment fabric is steeped in water or in chemical baths which
may be used in the course of the operations.

Improvements in the Manufacture of Parchment Fabric.
I, LOUIS FERDINAND DOBLER, of 95 Boulevard Beaumarchais, Paris, France,
Engineer, 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 :—
The object of this invention is to obtain parchment fabric designed to replace paper
in its various applications, such as for prints of any kind, drawings, water-colour
and other paintings, heliographs, photographs, book-binding, envelopes, and the like.
The improved parchment fabric is designed to be used in lieu of paper in all cases
where it is desired to combine with the qualities and properties of paper, great
strength.
The general mode of manufacturing the said parchment fabric consists in covering
any suitable fabric with a layer of paper or other similar material either in the form
of paste or in the form of a sheet. This layer is applied to one side or to both sides
of the fabric and is caused to adhere thereto by a size which is insoluble in water,
such as described in the Specification of Letters Patent No. 9949, dated July 15th 1887,

may be used in the course of the operations.

page_text: 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 :-
First. The method of manufacturing parchment fabric, characterized by the
employment of more or less fine fabric covered on one side or on both sides with a
layer of paper or other similar material in the form of a paste or of a sheet rendered
adherent by a size which is insoluble in water.
Second. The employment of this parchment fabric for impressions of any kind,
drawings water-colour and other paintings, photographs, heliographs, book-binding,
the manufacture of envelopes, and the like, and in general any applications where the
qualities of the paper must be combined with perfect strength.
