PROVISIONAL SPECIFICATION.
A New Method of Decorating Mirrors.
I, FREDERICK WEAVER OLIVER of 37 Huddart Street, Bow in the County of
Middlesex, Lithographer do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to imitate painted mirrors such as are now painted
by hand on the back of the glass and which are very costly.
Now according to this invention I produce the design by mechanical means on the
back of the glass whereby it is far less expensive than when painted on the front or
back of the glass as at prosent.
To carry out this invention I take a transfer paper, such as that described in the
specification of a former invention for which I obtained Letters Patent No. 981
dated Jan. 21st 1887 for "A new and improved method of producing colored trans-
parencies"; and print and dust thereon one or more whites (preferably two one
being drawn a little smaller than the work and the other the exact size thereof). The
design is now printed on the whites in the number of colors required to produce the
effects needed for instance for fruits flowers birds and other designs such as are now
painted on the mirror. I next have another drawing made a very little larger than
the design. I then print on to the design only, from the last named drawing a
mixture that will dry quickly with a strong tack such as a mixture composed of copal
varnish gold size, lithographic varnish and dryers care being taken that the mixture is
registered exactly on to the design only as the mixture must not touch the glass at
any other place than where the design is otherwise when silvering the glass, the silver
will not adhere, should any varnish be outside the design; the main feature of this
invention being the printing of the transfer mixture on the design only, whereas in
the ordinary way of transferring, the varnish is placed all over the paper and impres-
sion and the material that is to receive the transfer and consequently the glass could
not be silvered.
The object of the whites is to form a base for the colors and at the same time act
as a backing to prevent the solutions employed after silvering from acting on the
colors and so destroying their brilliancy. It is obvious that instead of printing the
mixture on the design as aforesaid it might be painted on but of course this would
involve far more labor. When the mixture which has been printed or painted on the
design is nearly dry, the impression is well rubbed down on the glass, the paper wetted
off and the glass washed quite clean, the work is well dried and the glass is then ready
for silvering.

COMPLETE SPECIFICATION.
A New Method of Decorating Mirrors.
I FREDERICK WEAVER OLIVER of 37 Huddart Street Bow in the County of
Middlesex, Lithographer do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
The object of this invention is to imitate painted mirrors such as are now painted
by hand on the back of the glass and which are very costly.
Now according to this invention I produce the design by mechanical means on
D437

page_text: the back of the glass whereby it is far less expensive than when painted on the front
or back of the glass as at present.
To carry out this invention I take a transfer paper such as that described in the
specification of a former invention for which I obtained Letters Patent No. 981 dated
Jan. 21st 1887 for "A new and improved method of producing colored transparencies"
and print and dust thereon one or more whites (preferably two one being drawn a
little smaller than the work and the other the exact size thereof). The design is now
printed on the whites in the number of colors required to produce the effects needed
for instance for fruits flowers birds and other designs such as are now painted on
mirrors.
I next have another drawing made a very little larger than the design. I then
print on to the design only from the last named drawing a mixture that will dry
quickly with a strong tack such as a mixture composed of copal varnish, gold size,
lithographic varnish and dryers care being taken that the mixture is registered exactly
on to the design only as the mixture must not touch the glass at any other place
than where the design is otherwise when silvering the glass for mirrors the silver will
not adhere should any varnish be outside the design; the main feature of this inven-
tion being the printing of the transfer mixture on the design only whereas in the
ordinary way of transferring, the varnish is placed all over the paper and impression
and the material that is to receive the transfer and consequently the glass can not be
silvered for mirrors.
The object of the whites is to form a base for the colors and at the same time act. as
a backing when on plain glass and to prevent the solution employed in silvering the
glass for mirrors from acting on the colors and so destroying their brilliancy.
It is obvious that instead of printing the mixture on the design as aforesaid it might
When the mixture
be painted on, but of course this would involve far more labor.
which has been printed or painted on the design is nearly dry, the impression is well
rubbed down on the glass, the paper wetted off and the glass washed quite clean,
the work is well dried and the glass is then realy to be silvered in order to produce
a decorated mirror.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what
I claim is:-
The method of decorating mirrors substantially as described.
