PROVISIONAL SPECIFICATION.
An Improved Material for Making Doors and Windows Air Tight.
I, ERNST MITTELSTEN-SCHEID, Manufacturer, of 52, Diekerstrasse, Barmen,
in the Empire of Germany, do hereby declare the nature of this invention to be
as follows:-
-
The present invention refers to an improvement in the materials hitherto used
for making doors and windows air tight, which materials possessed the great dis-
advantage that after use they were not sufficiently elastic to keep the air out
perfectly.
The present invention obviates this difficulty by means of list or a band with
a cord or plush border woven or plaited on, being used as the air tight material.
On the accompanying drawing an example of the invention is shown.
Figs. 1-3 represent the arrangement of the air tight material to a door, Figs. 4
and 5 are examples of the material.
This air tight material consists of list or a band of any desired width to which
a cord, chenille or plush border of any desired size is plaited or woven, the
production being effected by any suitable means. The material may be wholly
or partially of wool or cotton. To prevent its absorption of moisture the material
is impregnated by any suitable method.
The material can be made either colored or uncolored.

An Improved Material for Making Doors and Windows Air Tight.
I, ERNST MITTELSTEN-SCHEID, Manufacturer, of 52, Diekerstrasse, Barmen,
n the Empire of Germany, 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 present invention refers to an improvement in the materials hitherto used
for making doors and windows air tight, which materials possessed the great dis-
advantage that after use they were not sufficiently elastic to keep the air out
perfectly.
The present invention obviates this difficulty by means of list or a band with
acord or plush border woven or plaited on, being used as the air tight material.
On the accompanying drawing an example of the invention is shown. Figs. 1-3

page_text: represent the arrangement of the draught excluding material to a door, Figs. 4
and 5 are examples of the draught excluding material.
This draught excluding material consists of list or a band of any desired width
to which a cord, chenille or plush border of any desired size is plaited or woven,
the production being effected by any suitable means. The material may be wholly
or partially of wool or cotton.
.
The material can be made either colored or uncolored.
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:
1. A draught excluder for use in connection with doors and windows, consist-
ing of a band or list, to which a cord or plush edge is suitably fastened by
weaving or plaiting.
2. An improved material for making doors and windows air tight substantially
as described with reference to the drawings.
