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 MANUFACTURE OF MOULDINGS SUITABLE FOR PICTURE FRAMES AND THE
LIKE
"
Sealed the 8th March 1878, and dated the 27th November 1877.
PROVISIONAL SPECIFICATION left by the said Adam Cyrus Engert at the
Office of the Commissioners of Patents on the 27th November 1877.
ADAM CYRUS ENGERT, of Three Mills Lane, Bromley-by-Bow, in the County of
Middlesex. "IMPROVEMENTS IN THE MANUFACTURE OF MOULDINGS SUITABLE FOR
PICTURE FRAMES AND THE LIKE'
"
This Invention has for its object improvements in the manufacture of mouldings
suitable for picture frames and the like. These mouldings are at present produced
by applying a suitable composition upon a foundation of wood, and when a fluted
or line pattern has been required, it has been obtained either by cutting away the
composition when dry and hard with a sharp steel gouge, or else by pressing the
moulding with an embossing tool whilst the composition was still soft.
In order, according to this Invention, to produce a fluted or line pattern, I take
the moulding when the composition is dry and hard, and I bring a revolving tool
into contact with it at the part where the flute is required to be formed. The tool
is moistened, and by carrying the moisture to the composition, it softens it where
the Bute is required, and the tool then displaces or smooths away the softened
composition until a flute of the desired depth is produced. The machine then
makes a forward step equal to the distance between the flutes, and another flute is
similarly produced, and so on; or the machine may be arranged to produce two or
more flutes at a time.
In addition to flutes I can produce in a similar manner other simple patterus.

"
This Invention has for its object improvements in the manufacture of mouldings
suitable for picture frames and the like; for example, mouldings for ornamenting
panels in rooms, on doors, furniture, and so forth. These mouldings are at present
produced by applying a suitable composition upon a foundation of wood, and when
a fluted or line pattern has been required, it has been obtained either by cutting
away the composition when dry and hard with a sharp steel gougo, or else by
pressing the moulding with an embossing tool whilst the composition was still
soft.
In order, according to this Invention, to produce a fluted or line pattern, I take
the moulding when the composition is dry and hard, and I bring a revolving tool
into contact with it at the part where the flute is required to be formed. The tool
is moistened, and by carrying the moisture to the composition, it softens it where
the flute is required, and the tool then displaces or smooths away the softened com-
position until a flute of the desired depth is produced.
The annexed Drawing represents the tool which I prefer to employ. This tool is
made of steel, and has raised rings upon it corresponding to the flutes it is desired
to produce on the moulding. When in use it is rotated at a high velocity (a speed
of from 500 to 1000 revolutions per minute will be found suitable), and notches
may with advantage be cut in the raised rings, as the Drawing indicates, to enable
them the better to clear away the material which they rub away from the surface
of the moulding.
The moulding is formed with a concavity in it to receive the fluted pattern in
the same way as mouldings to be fluted by hand labour are commonly formed, and
before submitting the moulding to the action of the tool, it is prepared by coating
it with composition; a mixture of size or glue and whitening is that which is com-
monly employed; or the composition described in my Provisional Specification,
No. 1364, in the present year may be used. The composition is allowed to become
quite hard, the moulding to be fluted is then clamped or held in an horizontal
position, and the tool is brought down against it in the concavity prepared to
receive the fluted pattern.
The pressure of the tool upon the work is maintained uniformly by a weight or
by a spring, and the tool is moistened by a spray of water directed upon it. A few
seconds suffice to form the flutes to the proper depth, and the tool is then lifted;
the moulding is moved on a distance exactly corresponding to the length of work
which the tool can perform at one action, and then the tool is brought down again
into the concavity in the moulding to produce other flutes in continuation of the series
already commenced. As the moulding passes away from the tool, its surface is
wiped with a soft sponge to remove all remaining debris and moisture.
Where the concavity in the moulding is not of the same curvature as the tool,
the tool may receive a lateral movement whilst in contact with the work. This
movement may be controlled by a template or guide surface corresponding to the
curvature of the concavity of the moulding.
.
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 the production of fluted
mouldings suitable for picture frames and the like, by means of a rotating tool
applied with moisture upon the composition which forms the face of the moulding

page_text: in such manner as to rub away the composition at the places where the flutes are
to be formed, substantially as described.
In witness whereof, I, tho said Adain Cyrus Engert, have hereunto set my
hand and seal, this Twenty-fourth day of May, in the year of our Lord
One thousand eight hundred and seventy-eight.
