This Invention consists in filling up the interstices in tissues of the kind
specified with compounds oftransparent and opaque substances, which may be

thus treated may be ornamented with any enamelled design, so as to render

SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Frederick Tolhausen in the Great Seal Patent Office on
the 26th November 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
TOLHAUSEN, Civil Engineer and Patent Agent, 17, Faubourg Montmartre,
Paris, France, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-seventh day of May, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Frederick Tolhausen, Her special licence that I, the said Frederick
Tolhausen, my executors, administrators, and assigns, or such others as I, the
said Frederick Tolhausen,iny executors, administrators, and assigns,should at
any time agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "A NEW
OR IMPROVED METHOD OF APPLYING VARIOUS MINERAL AND ORGANIC SUBSTANCES TO
WIRE GAUZE, METALLIC, AND ASBESTOS TISSUES, FOR RENDERING SAID TISSUES
AVAILABLE FOR ORNAMENTAL AND USEFUL PURPOSES," a communication from
Edouard Heinhold, a person resident at No. 17, Faubourg Montmartre, afore-
said, upon the condition (amongst others) that I,the said Frederick Tolhausen,
my executors or administrators, by an instrument in writing under my, or their,
or one of their hands and seals, should particularly describe and ascertain the

page_text: nature of the said Invention, and in what manner the same was to be per-
formed, and cause the same to be filed in the Great Seal Patent Office
within six calendar monthis next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said Frederick Tolhausen, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
This Invention consists in filling up the interstices in tissues of the kind
specified with compounds of transparent and opaque substances, which may
be coloured by means of gum-lac colours mixed with varnish or gelatine, by
which process I render said metallic or asbestos tissues fit to be used for
ornamental purposes, such as blinds, signs, lamps, and lanterns, and so forth.
When it is desired to use said tissues for roofing,piping, and the like purposes,
I render them impervious by applying putty, tar, pigments, and similar sub-
stances. I also crystallize, glaze, vitrify, and enamel metallic and asbestos
tissues with silicious matters by the application of heat; for piping and plane
Surfaces, I sometimes prefer to impregnate them with ceramic substances,
such as clay, and bake them in them in the oven. The metallic tissues thus
treated may be ornamented with any enamelled design, so as to render them
fit for artistic wainscoating, roofing, and so forth. In practice I generally
pound or pulverize the crystalline matter and dissolve it by means of suitable
acids or fluxes, which solution is then spread over and on the wire gauze, so as
to fill up the interstices and cover the wires. The sheets thus prepared are
baked in a furnace similar to those used in manufacturing porcelain. The
colours may be mixed in the solution or applied after baking the sheets; also
the said sheets may be ornamented with glass colours and gilt by fire.
Instead of pulverizing crystalline matter, the pieces of wire gauze may be
laid flat on metallic tables or surfaces, and a crystalline solution poured over
them, immersing the sheets, which are then treated by a process similar to
silvering glasses. The wire gauze may be shaped into any desirable form,
such as decanters, bottles, and so forth, and the glass or crystalline blown into
these forms. Amongst the organic matters to be employed for a certain class
of articles, I would mention the different kinds of varnish, gelatine, and india-
rubber, which I use for coloured and transparent articles, and gutta percha,
tar, plaster of Paris, and compounds of said substances, which latter are used
to produce opaque or non-transparent articles. All these substances are to be
applied either by immersion or by means of the brush.
-

page_text: The following are some of the principal useful and ornamental articles to
which the improved wire gauze and asbestos tissue are-applied:-
Roofing and coverings for buildings and ships, sky-lights, wainscoating and
ceilings, sign boards, basso relievos, ornamental furniture, picture frames
artificial flowers and articles for transparent illumination, blinds and lanterns
piping baskets and flower pots, shades, also as a substitute for faïence, china
and earthenware.
In witness whereof, I, the said Frederick Tolhausen, have hereunto set
coal this Tmonty fourth day of November AD 1862
