I LOUISE WINTERHOFF of 2 Grove Road Saint Anns Road Stamford Hill in the
County of Middlesex Wife of Frederick Winterhoff of the same place Lithographer
do hereby declare the nature of my invention for A NEW OR IMPROVED PROCESS
FOR DECORATION OF GLASS AND OTHER SUBSTANCES FOR DECORATIVE AND ADVER-
TIZING PURPOSES to be as follows:-
For transparent Glass for window decoration advertisements and such purposes
I clean the article for the reception of the Print or Picture with white Chalk and
water and allow it to dry and then surface Indian or any other unsized paper with
a solution of Starch whitening and glycerine and print on such paper by Litho-
graphic printing process the Picture I desire to use and then transfer such Picture
on the cleaned article and wash the paper off.
When the article is dry I surface the print now on the article with a ground
equal all over and dust over this a powdered colour according to the back ground
required and let same dry.
For Glass tiles for decorative purposes when dry as lastly mentioned I coat the
glass with a solution of Asphalte tar or any other suitable substance and when still
damp I dust some saw dust or any other suitable substance over the Asphalte and
let the same dry.
I then coat the saw dust over with Asphalte or other suitable substance and let
same dry when the tile is ready for putting on the wall.

I, LOUISE WINTERHOFF Wife of Frederick Winterhoff Lithographer late of
2 Grove Road St Anns Road Stamford Hill now at 6 Eyot Gardens St Peters
Square Hammersmith West in the County of Middlesex 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 :-
For transparent Glass for window decoration advertizement and such other
purposes
I take white ruby or any other Glass clean the same with chalk and water
very clean and put the same on the side until I require I then take 2 ounces
White Starch dissolve this in a little cold water and pour on the same boiling water
so that this will have the thickness of Treacle I then add a pound of Glycerine
3 fluid ounces of dissolved and very clean filtered Gum Arabic of best quality
to the boiled Starch and mix this properly together with this mixture I coat
Indian or any other unsized paper very even and carefully over and hang the same
to dry when dry I coat the same paper in the same way twice over again but I use
each time fresh mixture as before when dry then the paper is ready for use I then
boil the following articles proper together to use as Printing ink.
1 pound of Purified Beef, or any other Suet.
1 ounce Burgundy Pitch.
White Venice Turpentine.
lb of Mastic in drops.
lb of Thin Litho Varnish.
lb of Thick Litho Varnish.
8 ounces of Bees Wax.
1 lbs Litho Printing Ink.
1 ounce of Lamp black.
When this-is properly boiled and cold I take as much of the above as I require
for printing and mix it with half the amount of Brunswick black or any other
boiled Asphalte with some dry Oak or Carriage Varnish in it I now draw my
picture Portrait Landscape or any other design on grained Transfer paper or
I draw the same direct on Stone Zinc or any other material from which I can make
a printing plate but I prefer to draw on the above grained paper and the coarsest
I can obtain and transfer the same to a Litho stone or a patent Litho plate and
prepare the same in the usual Lithographic manner.
I then print with the last named ink on the first named paper and put this
print between damp paper and when damp enough place it on clean glass and pass
it between two India Rubber Rollers with great pressure I then sponge the paper
over with cold water remove after a few minutes the paper from the glass, there
will be nothing more left from the print on the paper the print is now as sharp on
the glass as if on paper I then wash the glass well over the print with clean cold
water and let the glass dry When dry I dust the print over with very fine
powdered white Rosin or Asphalte either together or separate or any other Resinous

page_text: substance. After this I clean the print well so that there is no powder left on the
glass where there is no print and dry the same in a stove.
This ornamental glass or other article is now ready for either to put an equal
ground all over with any colour I require or I acid the same with fluoric acid out
or I silver it.
For Glass Tiles for wall decoration purposes when the equal ground is all over
and dry I coat the ground on the glass with a solution of Asphalte tar varnish or
any other suitable substance and when still damp I dust some sawdust or any other
suitable substance over the Asphalte and let the same dry I then coat the sawdust
over with Asphalte or other suitable substance and after this dry the same
gradually in a stove then these Glass Tiles are ready for putting on the wall.
It will thus be seen that in printing ornaments on to glass by this lithographic
or any other printing process the above described improved process is superior in
its working and results to all other methods in present use acknowledged by high
authority and experts.
The proportions of the mixture for paper and ink-as above given-are not
absolute but such as I have found to answer well and I can prepare the same and
their ingredients in any quantity.
Having now described the nature of my said Invention and in what manner the
same is or may be performed what I claim as my Invention is-
Firstly. The method of preparing Transfer paper and ink as described for
decoration on glass through lithographic or any other printing process.
Secondly. The method of bringing my picture portrait or any design from the
stone or as above described on to the glass through damping and pressing between
two India Rubber Rollers.
Thirdly. Putting an equal ground over the print so that the picture is
transparent.
Fourthly. The etching out of these prints by Fluoric Acid.
Fifthly. The silvering of these prints.
Sixthly. The dusting over with fine powdered resin or Asphalte or any resinous
substance and the drying in a stove.
Seventhly. The using of grained paper as described for this process.
