Year: 1870

page_text: LETTERS PATENT to William Thomas Guyatt, of Bedford Row, in the
County of Middlesex, for the Invention of "AN IMPROVED PROCESS
FOR MARKING
RAILWAY AND OTHER TICKETS, TRADE-MARK LABELS,
PROVISIONAL SPECIFICATION left by the said William Thomas Guyatt
at the Office of the Commissioners of Patents, with his Petition, on
the 30th August 1870.
"
I, WILLIAM THOMAS GUYATT, of Bedford Row, in the County of
Middlesex, do hereby declare the nature of the said Invention for
"AN IMPROVED PROCESS FOR MARKING RAILWAY AND OTHER TICKETS, TRADE-MARK
LABELS, COMMERCIAL CARDS, OR SIMILAR PRINTED FORMS," to be as follows,
that is to say :-
-
My Invention has reference to the employment of chemical fluids for
marking or forming authenticated numbers, figures, signatures, devices,
or otherwise upon railway, season, or other tickets, trade labels,
commercial cards, circulars, or similar printed forms in lieu of the old

page_text: system of printing as at present, by which means any counterfeiting or
imitating thereof is prevented, and consists in producing the said
numbers, marks, or devices indelably upon the tinted or plain surfaces
of the tickets, cards, or otherwise by writing with a pen, or printing from
a block, stone, or plate with a fluid composed of sulphuric acid, or of
muriatic acid, or the two acids aforesaid mixed or combined with vege-
table or mineral colours as required or used simply by themselves when
extracting tints from coloured surfaces, so as to leave the numbers or
devices light upon dark grounds or dark upon light ground, enabling in
like manner plain or enamelled surfaces of paper, card, linen, woollen
fabrics, parchment, vellum, or leather to be lettered, figured, or otherwise
by the chemical action of the said acids with or without a base.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Thomas Guyatt in the Great Seal Patent
'Office on the 27th February 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
THOMAS GUYATT, of Bedford Row, in the County of Middlesex, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirticth day of August, in the year
of our Lord One thousand eight hundred and seventy, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Thomas Guyatt, Her special
licence that I, the said William Thomas Guyatt, my executors,
administrators, and assigns, or such others as I, the said William
Thomas Guyatt, my executors, administrators, and assigns, should at
any time agree with and no others, from time to time and at all times
thereafter 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 "AN IMPROVED PROCESS FOR MARKING RAILWAY AND OTHER TICKETS, TRADE-
MARK LABELS, COMMERCIAL CARDS, OR SIMILAR PRINTED FORMS," upon the
condition (amongst others) that I, the said William Thomas Guyatt, my
executors or administrators, by an instrument in writing under my,

page_text: or their, or one of their hands and seals, should particularly describe
and ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great
Scal Patent Office within six calendar months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said William. Thomas Guyatt, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement (that is to say):-
My Invention has reference to the employment of chemical fluid or
ink for marking or forming authenticated numbers, figures, signatures,
devices, or otherwise upon railway, season, or other tickets, trade. labels,
commercial cards, circulars, or similar-printed forms. in. lieu of the old
system of printing as at present, by which said means any counterfeit or
imitation thereof is prevented, and consists in producing the said
numbers, marks, signatures, or devices aforesaid, indelibly upon the
tinted or plain surfaces of the tickets, cards, or otherwise by writing with
a pen or printing from engraved blocks, stones, dies, or plates with the
above fluid composed of sulphuric acid or of muriatic acid, or the two
acids aforesaid mixed and employed with vegetable or mineral colours as
required or used simply by themselves when extracting colours from
tinted surfaces, so as to leave the numbers, signatures, or devices aforesaid
light upon a dark ground or dark upon a light ground, enabling, in
like manner plain or enamelled surfaces of paper, card, linen, woollen.
fabrics, parchment, vellum, or leather to be lettered, figured, written, cr
otherwise by the chemical action of the said acids with or without a base.
And in order that my said Invention may be more fully understood,
and readily carried into effect, I now proceed to describe in detail the
mode of performing the same (that is to say):
My Invention consists, firstly, in the preparation and mode of
employing dyes obtained from mineral, vegetable, metallic, or other
organic matters for coloring or tinging the surfaces of card, pasteboard,
parchment, or otherwise as aforesaid.
And, secondly, in chemically acting upon the said stained or tinted
surfaces by means of a fluid or ink, so as to produce written marks or
inscriptions thereon indelibly and permanently stained, and thereby
prevents its being surreptitiously tampered with or erased, the said quid

page_text: or ink being composed of a solution of one part of sulphuric acid, (oil of
vitriol of commerce) to seven parts of water, or the said fluid may in like
manner be composed of two parts of muriatic acid to thirteen parts of
water, adding ammonia as required for checking or correcting any
deliquescent tendency (that is to say) :-
In applying the above process for signing or marking railway, season,
or other tickets, I cause the said card, pasteboard, or paper, constituting
the same to be tinted in the pulp or superficially dyed or stained with
any or all the following fixed colors or admixtures thereof, namely,
Mazarine blue, ultramarine blue, and light or Waterloo blues, Brunswick
emerald or other shades of green, cochineal, carmine, carnation, lilac,
lavender, pink, buff, primrose, chrome yellow, mauve, orange, or violet of
any required shade, a border line in plain or ornamental device is then
formed upon the coloured surface of the card or ticket whilst printing
the said numbers, marks, or otherwise aforesaid through the medium of
copper plates, lithographic or zincographic plates, or letter-press with a
solution of one part of sulphuric acid to seven parts of water, and for
enamelled glazed surfaces one part of sulphuric acid to fourteen parts
of water, whilst for plain or tinted pulp, card, or pasteboard, a solution
of the strength of one part of the acid to twenty-seven parts of water,
corrected with ammonia as before stated.
In conclusion to the foregoing description I would here briefly note
that the proportions and mode of preparing and employing the various
ingredients above referred to may receive such other modifications as in
practice may be found necessary.
Having now fully described and ascertained the nature of this my said
Invention, and the manner in which the same is to be performed and
carried into effect, I would have it clearly understood that I do not by
any means intend to confine myself to the precise details herein-before
set forth and described as the same may be otherwise varied without
departing from the general principle of this my said Invention, nor do I
claim as new and of my said Invention the exclusive use of the several
parts, combinations, and processes herein-before described, except when
the same are employed in and for the purposes of my said Invention,
which I hereby declare to consist,―
Firstly. In the mode of producing and employing coloured surfaces
for railway season tickets, or otherwise, as before described.

page_text: And, secondly, the preparation and combination of ingredients forming
the fluid or ink aforesaid for writing and printing indelibly upon tinted or
other chemically prepared surfaces, applicable to railway season tickets,
cards, or otherwise, in the manner and for the purposes herein-before
set forth and described.
In witness whereof, I, the said William Thomas Guyatt, have
hercunto set my hand and seal, this Twenty-seventh day of
February, in the year of our Lord One thousand eight hundred and
seventy-one.
Witness,
BALDWIN FULFORD WEATHERDON,
