AN IMPROVEMENT IN PRODUCING ORNAMENTAL PLASTERING OR STUCCO WORK
Year: 1856

page_text: LETTERS PATENT to Benjamin Ferrey, of Trinity Place, Charing Cross,
Architect, for the Invention of "AN IMPROVEMENT IN PRODUCING ORNAMENTAL
PLASTERING OR STUCCO WORK."
Sealed the 20th March 1857, and dated the 27th October 1856.
PROVISIONAL SPECIFICATION left by the said Benjamin Ferrey at tho
Office of the Commissioners of Patents, with his Petition, on the 27th
October 1856.
I, BENJAMIN FERREY, of Trinity Place, Charing Cross, Architect, do hereby
declare the nature of the Invention for "Ax IMPROVEMENT IN PRODUCING
ORNAMENTAL PLASTERING OR STUCCO WORK," to be as follows:-
This Invention has for its object an improvement in producing ornamental
plastering or stucco work, and consists in so performing such work that
indented or impressed ornamental patterns are obtained on the surfaces as the
plastering proceeds, and whilst the materials are still sufficiently plastic to
admit of the desired impressions or indents being made. For this purpose
ornamental pattern plates are formed with the pattern cut through them,

page_text: similar to stencil plates, but sufliciently strong to admit of their being pressed
into the finishing coating of plaster, such plates being of a thickness depending
on the depth of the desired impression, and the edges of the pattern are
inclined, so as not only to enter more freely into the plaster, but also that
the impressing plates or surfaces may "deliver" or come away from the im- 5
pressions produced without injury to the impressions.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Benjamin Ferroy in the Great Seal Patent Office on the
27th April 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BENJAMIN
FERREY, of Trinity Place, Charing Cross, Architect, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-seventh day of October, in the year of our
Lord One thousand eight hundred and fifty-six, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Benjamin Ferrey, IIer special licence that I, the said Benjamin Ferrey,
my executors, administrators, and assigns, or such others as I, the said
Benjamin Ferrey, my executors, administrators, and assigns, should at any timo
agree with, and no others, from time to time and at all times thereafter during
the term therein expressed, should and lawfully might make, uso, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Mau, an Invention for "AN IMPROVEMENT IN PRODUCING
ORNAMENTAL PLASTERING OR STUCCO WORK," upon the condition (amongst others)
that I, tho said Benjamin Ferrey, my executors or administrators, by an in-
strument in writing under my, or their, or one of their hands and scals, 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 Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Benjamin Ferrey, do hereby declare the
nature of the said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following state-
ment thereof, that is to say:-
This Invention has for its object an improvement in producing ornamental.
plastering or stucco work, and-consists in so so performing such work that.

page_text: indented or impressed ornamental patterns aro obtained on the surfaces as the
plastering proceeds, and whilst the materials are still sufficiently plastic to
admit of the desired impressions or indents being made. For this purpose
ornamental pattern plates are formed with the pattern cut through them,
similar to stencil plates, but sufficiently strong to admit of their being pressed
into the finishing coating of plaster, such plates being of a thickness depending
on the depth of the desired impression, and the edges of the pattern are
inclined, so as not only to enter more freely into the plaster, but also that the
impressing plates or surfaces may "deliver" or come away from the im-
pressions produced without injury to the impressions.
Having thus stated the nature of my Invention, I will proceed to describe
more fully the manner of performing the same.
The perforated plates used aro by preference made of metal, and of a thick-
ness corresponding with the intended relief to be given to the ornamental
patterns. The pattern in each case is to be cut through the plates, and the
sides of the openings through the plates are to be made slightly inclined, to
facilitate the delivery of the plates from the plastic surfaces. At the back of
each perforated pattern plate is fixed a handle or handles to aid the workman
in applying and removing the plate:
The finishing coat of plaster or cement having been laid on, the workman
impresses such surfaces with a perforated ornamenting plate, and it is found
desirable not completely to imbed the plate in the first instance, but only partly
to impress the plate into the surface, and then, after similarly impressing the
other contiguous parts, in like manner to return to the parts first impressed, in
order to deepen the impressions. In pressing the ornamenting perforated
plates into the soft and plastic surfaces, the workman should give to the plates
a tremulous motion, by which not only will the act of pressing the ornament-
ing plates into the soft surfaces be facilitated, but the ornamenting plates will
be found more readily to leave the impressions without injuring the sharpness
of the edges of the parts in relief. It will be evident, that in place of pressing
the perforated ornamenting plates into the plastic surfaces after they have
been laid on, the parts in relief may be applied through the perforated
ornamenting plates whilst the parts below are in a moist or plastic state, in
which case the parts in relief may, if desired, be of a different color to the
sunk parts. This mode of working, when using ornamenting perforated plates
to produce the description of ornamented surfaces, above explained, may with
advantage be resorted to when the plaster or stucco work is on walls or brick-
work; but when the work is on laths, the perforated ornamenting plates are

page_text: preferred to be used by impressing them into the fresh surfaces, as first
explained.
In witness whereof, I, the said Benjamin Ferrey, have hereunto set my
hand and seal, this Twenty-seventh day of April, in the year of our
Lord One thousand eight hundred and fifty-seven.
Witness,
S. CARPMAEL.
