page_text: I, FREDERICK WEAVER OLIVER of 37 Huddart Street Bow in the County of
Middlesex Lithographer do hereby declare my said invention to be as follows:-
This invention has for its object the production of colored transparencies in
substitution for and imitation of painted or stained glass in a very effective manner
and at a moderate cost.
In order to carry out this invention I print on paper (prepared as hereafter
described) the design in very powerful colors and when this impression is dry 1 varnish
same and I also varnish the glass or other suitable transparent substance employed
upon which the design is to be produced and when both the varnishes are dry or
nearly so I lay the impression on the glass or other substance which has been
previously varnished as aforesaid and press it well down taking care to press out any
air bubbles that may have formed between the paper and the glass or other
substance.
I then heat the glass or other substance sufficiently to cause the varnish to become
"tacky" and then rub the impression well down and when the glass or other substance
is cool the paper is wetted and taken off and the whole of the design will be fixed on
the glass or other substance in transparent colors. I then well wash the glass or other
substance employed and wipe it dry after which I subject it to a good heat say 200
degrees to harden the varnish. I then varnish it on the printed side and again bake
and then polish it for better protection.
The paper aforesaid upon which I first print the design in colors for fixing to the
glass or other substance I prepare as follows:-I take plate or half plate paper
(preferably the latter) not too stout and give it two coats of starch and a coating of
gum arabic after which I highly roll it.
By the above method I am enabled to produce a very effective imitation of stained
or painted glass without having any paper fixed thereto and at the same time I do not
require to subject the glass (when this is employed) to pressure which would
break it.

page_text: 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:-
This invention has for its object the production of colored transparencies in
substitution for and in imitation of painted or stained glass in a very effective manner
and at a moderate cost.
In order to carry out this invention I print on paper (prepared as bereafter
described) the design in very powerful colors and when this impression is dry I
varnish same and I also varnish the glass or other suitable transparent substance
employed, upon which the design is to be produced and when both varnishes are dry
or nearly so I lay the impression on the glass or other substance which has been
previously varnished as aforesaid and press it well down, taking care to press out any
air bubbles that may have formed between the paper and the glass or other substance.
I then heat the glass or other substance sufficiently to cause the varnish to become
tacky "and then rub the impression well down and when the glass or other substance
is cold, the paper is wetted and taken off and the whole of the design will be fixed on
the glass or other substance in transparent colors. 1 then well wash the glass or other
substance employed to thoroughly remove any composition that may have left the
paper with the transfer colors and wipe it dry after which 1 subject it to a good heat
say 20° Fahrenheit to harden the varnishes. I then varnish it on the printed side
and again bake and then polish it for better protection; The paper aforesaid upon
which I first print the design in colors for fixing to the glass or other substance I
prepare as follows:-1 take plate or half-plate paper (preferably the latter) not too
stout and give it two coats of starch prepared with boiling water and a coating of gum
arabic dissolved in water after which I highly roll the paper thus prepared. By the
above method I am enabled to produce a very effective imitation of permanently
stained or painted glass without having any paper fixed thereto and at the same time
I do not require to subject the glass (when this is employed) to pressure which would
break it, and I obtain by this method perfect finished transparencies without the
necessity of any touching up or painting, and great rapidity of production.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed 1 declare that what I claim is:-
The production of colored transparencies substantially as described.
