Year: 1850

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
ARCHIBALD BROOMAN, of the firm of Messrs. J. C. Robertson & Co., of 166,
Fleet Street, in the City of London, Patent Agents, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Scal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Seventh day of March
One thousand eight hundred and fifty, in the thirteenth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Richard Archibald Brooman, my exors, adñors, and assigns, Her especial
licence, full power, sole privilege and authority, that I, the said Richard
Archibald Brooman, my exors, admors, and assigns, or such others as I, the
said Richard Archibald Brooman, my exors, admors, or assigns, should at any
time agree with, and no others, from time to time and at all times during the
term of years therein expressed, should and lawfully might make, use, exercise,
and vend, within England, Wales, and the Town of Berwick-upon-Tweed, in
the Islands of Guernsey, Jersey, Alderney, Sark, and Man, and in all Her
Majesty's Colonies and Plantations abroad, the Invention of "IMPROVEMENTS
IN TYPES, STEREOTYPE PLATES, AND OTHER FIGURED SURFACES FOR PRINTING PROM,"
communicated to me from abroad; in which said Letters Patent is contained
a proviso, that I, the said Richard Archibald Brooman, shall cause a particular
description of the nature of the said Invention, and in what manner the same
is to be performed, by an instrument in writing under my hand and seal, to be

page_text: inrolled in Her Majesty's High Court of Chancery within six calendar months
next and immediately after the date of the said in part recited Letters Patent,
as in and by the same, reference being thereunto had, will more fully and at
large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Richard Archibald Brooman, do hereby declare that the nature of the Inven-
tion communicated to me as aforesaid, and in what manner the same is to be
performed, are fully described and ascertained in and by the present Speci-
fication thereof, reference being had to the illustrative Drawing hereunto
annexed, that is to say:-
The Invention consists in covering, coating, or plating the surfaces of types,
stereotype plates, and other figured surfaces for printing from, whether cast or
engraved or punched, or however otherwise produced, or at least so much of
the said surfaces as are exposed to wear in the course of being printed, with
some protecting metal, which will encrease their durability without impairing
their sharpness.
The types and other printing surfaces have the required covering or coating
precipitated upon them by the action of galvanic electricity, and the metal that
I find to answer best for the purpose is copper. The galvanic battery being
in readiness, a solution of a salt of copper (supposing copper to be the metal
intended to be precipitated) is put into the proper cell of the battery, and the
printing surface having been previously thoroughly cleaned, is immersed in the
solution, when the copper is precipitated upon it in the usual way.
When types are to be coated, in which case the faces only need be protected,
a number of them are made up into parcels, of a convenient size for operating
upon, and tied together, and in that state they are immersed in the solution of
salt of copper to the depth only of the shoulder or line a, a, a, as represented
in the Drawing annexed. The deposit of copper then takes place on the face
of the type, or part below the line a, a, colored red in the Drawing.
And having now described the nature of the Invention communicated to me
as aforesaid, and in what manner the same is to be performed, I declare that I
claim the covering, coating, or plating of the surfaces of types, stereotype
plates, and other figured surfaces for printing from, in whole or in part, with
some protecting and preserving metal, as before described.
In witness whereof, I, the said Richard Archibald Brooman, have hereunto
set my hand and seal, this Seventh day of September, in the year of our
Lord One thousand eight hundred and fifty.
R. A. (L.B.) BROOMAN.
