page_text: LETTERS PATENT to Adam Cyrus Engert, of Three Mills Lane, Bromley-by-
Bow, in the County of Middlesex, for the Invention of "IMPROVEMENTS IN
THE PRODUCTION OF MOULDINGS."
Sealed the 12th July 1878, and dated the 5th April 1878.
PROVISIONAL SPECIFICATION left by the said Adam Cyrus Engert at the
Office of the Commissioners of Patents on the 5th April 1878.
ADAM CYRUS ENGERT, of Three Mills Lane, Bromley-by-Bow, in the County of
Middlesex. "IMPROVEMENTS IN THE PRODUCTION OF MOULDINGS."
This Invention has for its object improvements in the production of mouldings.
At the present time in order to prepare a wooden moulding for gilding it is usual
to apply to it a preparatory coating, consisting of whitening mixed with size or
gluc. Now unless the size or glue employed in this preparation or coating be of a
quality which it is difficult to obtain the surface will be liable to crack or blister,
and it will not bear the action of the burnishing tool.
Now according to my Invention I add to the mixture of whitening and size or
glue, oily or fatty matter of a non-drying nature, for example, olive oil I find to be
suitable, and so I give to the preparation or coating the requisite softness, tenacity,
and pliability.
The ornaments and more complicated parts of mouldings are usually formed from
a composition consisting of linseed oil, glue, rosin, and whitening; now I add to the
ductility of this composition by the addition to it of oily or fatty matter of a non-
drying nature; I also add saccharine matter to the composition when I desire that
the ornaments should remain pliable for some time after moulding.
I in some cases incorporate coloring matter, or bronze, or metallic powder with
the other ingredients of the composition, and also of the preparation referred to
above, which for some uses will render the application to the ornaments of metallic
leaf or paint unnecessary; or if the ornaments or mouldings be afterwards coated

page_text: the color in the composition or preparation will improve the appearance, and any
accidental damage that they may receive will be less apparent.
When using some qualities of glue there is difficulty in combining it with the
linseed oil; I effect the combination readily by the addition of saccharine matter.
I also combine linseed oil with the glue which I employ to cement together the
different parts of mouldings, in order that it may not be affected by the moisture
of the atmosphere.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Adam Cyrus Engert in the Great Seal Patent Office ou the 4th
October 1878.
ADAM CYRUS ENGERT, of Three Mills Lane, Bromley-by-Bow, in the County of
Middlesex. "IMPROVEMENTS IN THE PRODUCTION OF MOULDINGS."
This Invention has for its object improvements in the production of mouldings.
At the present time in order to prepare a wooden moulding for gilding it is usual
to apply to it a preparatory coating, consisting of whitening mixed with size or
glue. Now unless the size or glue employed in this preparation or coating be of a
quality which it is difficult to obtain the surface will be liable to crack or blister,
and it will not bear the action of the burnishing tool.
Now according to my Invention I add to the mixture of whitening and size or
glue, oily or fatty matter of a non-drying nature, for example, olive oil I find to be
suitable, and so I give to the preparation or conting the requisite softness, tenacity,
and pliability.
Ornaments and more complicated parts of mouldings are usually formed from a
composition consisting of linseed oil, gluo, rosin, and whitening; now I add to the
ductility of this composition by the addition to it of oily or fatty matter of a non-
drying nature; I also add saccharine matter to the composition when I desire that
the ornaments should remain pliable for some time after moulding.
I in some cases incorporate coloring matter, or bronze, or metallic powder with the
other ingredients of the composition, and also of the preparation referred to above,
which for some uses will render the application to the ornaments of metallic leaf
or paint unnecessary; or if the ornaments or mouldings be afterwards conted the
color in the composition or preparation will improve the appearance, and any
accidental damage that they may receive will be less apparent.
When using some qualities of glue there is difficulty in combining it with the
linseed oil; I effect the combination readily by the addition of saccharine matter.
I also coinbine linseed oil with the glue which I employ to cement together the
different parts of mouldings in order that it may not be affected by the moisture of
the atmosphere.

page_text: In order that my said Invention may be most fully understood and readily
carried into effect I will proceed to describe more in detail the manner in which I
prefer to operate.
To prepare wooden mouldings for gilding I take the ordinary mixture of
whitening and sizo or glue, with which it is the custom at present to coat such
mouldings, and to each cwt. of such mixture I add half a pint of olive oil or other
non-drying fatty matter. The oil or fatty matter is mixed very thoroughly with a
small quantity of whitening, which should be quite dry and warm, and so is brought
to a putty-like consistency; it is then intimately combined with the whitening
mixture in a mill, such as is usually employed in making this mixture. This pre-
paratory coating is not liable to crack or blister, and it bears well the action of the
burnishing tool.
A composition to be moulded to produce ornaments and complicated parts of
mouldings I make in the following manner:-I take the ordinary mixture of linseed
oil, glue, rosin, and whitening used for these purposes, and to make the glue com-
bine more thoroughly with the linseed oil I add to each cwt. of the dissolved glue
from / to lb. of sugar or saccharino matter dissolved in a small quantity of hot
water. This I mix with the glue as soon as it is melted. To each cwt. of the
mixture I also add half a pint of olive oil or other non-drying fatty matter pre-
pared and mixed as described in respect to the former composition for covering
wooden mouldings. The non-drying oil or fat in this composition gives to it much
greater ductility than is possessed by the composition at present in use.
When I desiro that the ornaments should remain pliable for some time after
moulding, in order that they may be fitted on to curved surfaces or otherwise,
I use three or four times the quantity of sugar or saccharine matter before
mentioned.
The composition may be employed in the production of mouldings of any required
length and width, and is also applicable for producing rosettes and other ornaments
for decorative purposes.
To produce colored mouldings or ornaments I add coloring matter (preferably in
the shape of powder), and intimately mix it with the composition from which such
mouldings or ornaments are to be made. To produce bronze-like ornaments I
incorporate bronze powder.
In the preparation of the glue to be employed in fixing together the parts of
mouldings and for attaching ornaments I take twenty ounces of glue, which I melt
with water in the usual way; I add one ounce of sugar dissolved in a small
quantity of water, and I then stir in little by little, one ounce of linseed oil. No
difficulty will be experienced in making a perfect mixture, and the ingredients will
not afterwards separate. When gluo prepared in this manner is employed the
parts attached by incans of it are inuch less liable to separate than when glue alone
is used.
Having thus described the nature of my said Invention and the manner of per-
forming the same, I would have it understood that I claim in the production of
mouldings or moulded ornaments,-
First. The use as a basis for gilding or otherwise of a preparatory coating, con-
sisting of whitening and size or glue, together with oily or fatty matter of a non-
drying nature.
Second. The use of a moulding composition, consisting of linseed oil, glue, rosin,
and whitening, together with oily or fatty matter of a non-drying nature.
Third. The addition of saccharine matter to a moulding composition, consisting
of linseed oil, glue, rosin, and whitening, cither with or without oily or fatty matter
of a non-drying nature.
Fourth. The use of a coating for wood mouldings, consisting of whitening, size,
or glue, and oily or fatty matter of a non-drying nature, together with coloring
matter or bronze or metallic powder.
Fifth. The addition to a moulding composition, consisting of linseed oil, glue,
rosin, and whitening, of colouring mattor, or bronze, or metallic powder.

page_text: Sixth. The addition to glue to be employed for connecting the parts of mouldings
or for fixing ornaments, of linseed oil and saccharine matter.
In witness whereof, I, the said Adam Cyrus Engert, have hereunto set my
hand and seal, this Fourth day of October, in the year of our Lord One
thousand eight hundred and seventy-eight.
