I, LEONARD BRIERLEY, of Birmingham, in the County of Warwick,
Manufacturer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN ORNAMENTING JAPANNED SURFACES, AND IN MACHINERY OR
APPARATUS POR, THAT PURPOSE," to be as follows:-
My Invention consists of the improvements herein-after explained, in
producing designs in colour or in gold leaf, metal leaf, or bronze, on the
surfaces of japanned articles, and in the machinery or apparatus herein-after
described, to be employed in producing the said designs.
In ornamenting japanned surfaces according to my Invention I employ a
roller, on the cylindrical surface of which the ornamental forms to be produced
on the surface to be ornamented are made in relief. The said roller is elastic.
or flexible, and is made in the manner herein-after described. With this
roller I take up colour or gold size, when the design is to be produced in gold.
leaf, metal leaf, or bronze, and I pass the roller over that part of the surface
on which the ornament is to be produced. By rolling the roller charged with.
colour or gold size over the surface to be ornamented the ornament in relief
on the roller leaves the colour or gold size with which it is charged on the
said surface. When gold size has been used, gold or metal leaf, or bronze is

the following manner :-I prepare a mould having a cylindrical hole through
it of the size of the roller to be made. On the inner cylindrical surface of
the mould I form the pattern to be produced on the roller, the said pattern
being sunk in intaglio in the mould. The mould is made in two or more parts,
so that it may be readily engraved and easily put together and taken to pieces.
In using the mould to produce a roller, the parts of the mould are secured
together, and a cylinder of wood is placed in it to form the foundation of the
roller. I then pour into the mould through a jet hole provided for the purpose
some of the composition used for making printing rollers, and called printer's
composition, the said composition being liquified by heat. When the
composition has solidified by cooling I open the mould and remove therefrom
the cylinder of wood upon which the ornament sunk in the mould is produced
in relief in the said composition. I mount the cylinder of wood on which the
ornament has been cast upon an axis, and support the said axis by a handle,
by which it is rolled over the surface to be ornamented. Although I have
found the composition called printer's composition answer very well for
casting the ornament upon the roller, yet I do not limit myself thereto, as any
other composition or material which can be cast or moulded, and which is
elastic or flexible may be employed. For ornamenting flat surfaces I employ
a cylindrical roller, but when surfaces of a concave or convex figure are to be
ornamented I employ rollers the sectional figure of which is the reverse of
that of the said surfaces.
