I, ADAM CYRUS ENGERT, of Nos. 31 and 32, Tabernacle Row, in the
County of Middlesex, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN THE MANUFACTURE OF PLAIN AND ORNAMENTAL
MOULDINGS FOR PICTURE FRAMES AND OTHER USES, AND IN APPARATUS THEREFOR,'
to be as follows:-
This. Invention has for its object improvements in the manufacture of
plain and ornamental mouldings for picture frames and other uses.
In constructing mouldings for picture frames and for other uses I
eause suitable pieces of wood fashioned to the general form of the
moulding which it is desired to produce to pass under a vessel containing
composition, and as the wood passes under the vessel the composition
is pressed out through an orifice in a thin sheet, which is caused to
adhere to the wood by means of size which is applied to the wood
just before the sheet of composition comes in contact with it. Then

page_text: as the wood is made to travel on in the machine the composition is
pressed down upon its surface by a roller with a smooth face and
corresponding in form with the moulding; in this way a smooth or
comparatively smooth surface is obtained; then the wood with the
composition upon it is if necessary passed through a die which completes
the smoothing, cutting off, and rubbing down any inequalities that
may remain on the surface. To produce a pattern on the moulding
it is now passed under a roller on which the pattern is cut, and in
this way the pattern is impressed on the composition. Usually the
pattern will not extend over the whole width of the moulding, and
then the parts which do not receive the pattern remain smooth as they
were left by the roller and die. The moulding is now ready to be
gilded or otherwise finished, as is well understood. If a plain moulding
is required the use of the pattern roller is of course omitted.
In some cases I use the composition so thin that it will run from the 1
vessel containing it without pressure; in this case I generally apply the
composition to the wood in two or more layers to obtain the desired
thickness, and more than one layer may also sometimes be applied when
thick composition is used.
The method of working above described is applicable more especially 2
to fine and comparatively shallow patterns. For deeper patterns I spread
a suitable thick composition in the manner above described on a surface
of wood or other material to form for it a temporary support, and
to which it is made to adhere by means of size. This surface with
the composition upon it is made to travel on under a roller on which 2
the pattern is cut. The roller is applied with sufficient pressure to fill
the pattern.
The next process is to remove the ornament thus produced from
the remainder of the composition, for it is necessary to have a con-
siderable excess of composition in order that the pattern may be 3
sharply raised with a moderate pressure. This is done by causing the
supporting surface with the composition upon it as it travels forwards
to meet a knife, which slices off the pattern at a uniform depth
from the top of the figure. The moulded ornament thus obtained
is guided by rollers or in other convenient manner on to the surface 3
to which it is to be permanently fixed. This surface is usually a plain

page_text: moulding prepared in the manner already described, and it is made
to travel forward continuously in the machine at the speed at which
the ornament is produced, and the ornament as it is cut off is brought
in contact with it and made to adhere by means of size or suitable
cement.
