PROVISIONAL SPECIFICATION.
A New Fireproofing Device for Walls, Ceilings, and other Objects.
I CHARLES HUELSER of the firm of Huelser & Co. of 142 Fleet Street London,
Patent Agents, do hereby declare the nature of this invention, a communication to
me from abroad by A. Fenten of Essen af Ruhr in the Empire of Germany, Architect,
to be as follows:-
This invention relates to a device rendering walls ceilings vaults and other objects
fireproof and it consists in stretching impregnated cords of hemp or other suitable
material over the surfaces to be coated with plaster or cement. The cords are stretched
net-fashion alternately over pairs of pins provided at suitable distances on either side
of the upright flange of light T irons secured by means of screw bolts fixed in the
solid wall and nuts, or in any other convenient manner to the sides of the wall or
ceiling to be plastered. In case the T irons are to be fixed to iron supports they are
screwed onto the same by means of screw threaded holes bored therein.
Ca
To strengthen the net work when applied to ceilings, flat irons may be screwed over
the same along each beam.
After the network is secured, the plaster is put on, an average layer of 5 centimetrès
for walls and of 3 centimètres for ceilings being sufficient.
Walls, ceilings, vaults etc. covered in the above described mannor are absolutely fire-
proof this method being at the same time simpler and cheaper, than those heretofore
applied. It may also be utilized for fireproofing machine parts or other objects.
Dated this 6th day of November 1888.

COMPLETE SPECIFICATION.
A New Fireproofing Device for Walls, Ceilings, and other Objects.
I, CHARLES HUELSER of the firm of Huelser & Co. of 142 Fleet Street London, Patent
Agents, do hereby declare the nature of this invention, a communication to me from
abroad by A. Fenten, of Essen af Ruhr, in the Empire of Germany, Architect, 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 a device for supplying a fireproof covering for walls,
ceilings, vaults, machine parts and other objects, and it essentially consists in stretching
impregnated with soluble glass or other suitable fire proofing substance cords of hemp
or other convenient material net-fashion over the surfaces to be treated and subsequently
covering the same with plaster or cement.
Referring to the accompanying drawings, Sheet I illustrates the manner of covering
walls etc. with the new device, the cords being placed round pairs of pins provided in
small irons.
The latter are secured laterally by means of screw bolts suitably fixed in the solid
walls and nuts, and are nailed or screwed above and below to the beams or floor.
If the Tirons are to be secured to iron supports, screw threads are cut therein and
the irons fixed by aid of corresponding screws as shewn by B, Sheet I.
Sheet II indicates the method of applying the invention to ceilings, the cords being
stretched and secured in the same manner as with walls, while, in order to strengthen
the not work, flat irons are screwed or otherwise secured over the same along each
beam.
When the net work is ready, the plaster or cement is put on, an average layer of
5 centimetres for walls and of 3 centimetres for ceilings being sufficient.

page_text: Where the walls are interrupted by doors or windows, the T irons are secured to
the frames thereof.
The improved device and method afford an absolutely fireproof covering for the
walls, ceilings or objects treated, which is moreover much simpler and cheaper than
any method heretofore applied.
Having now particularly described and ascertained the nature of this inven
tion, and in what manner the same is to be performed I declare that what I
claim is:
1.) The application of cords of hemp or similar material stretched over walls,
ceilings or other objects for the purpose of securing plaster or cement thereto, substan-
tially as set forth.
2.) The application of cords of hemp or similar material impregnated with fire-
proofing substance and stretched over walls, ceilings or other objects for securing
plaster or cement and producing a fireproof layer, substantially as set forth.
Dated this 3rd day of August 1889.
