PROVISIONAL SPECIFICATION.
Improvement in Manufacturing Gelatine Surfaced Show Cards or
Advertising Tablets and the like.
WILLIAM FRANK PICKFORD 44 Durham Road Manor Park Essex Com-
mercial Traveller do hereby declare the nature of this invention to be as
follows:-
:-
This invention relates to the process of gelatining the surface of lithographed,
letterpress, block printed or collotyped show bills, show cards, pictures and the like
printed matter, which may be designed or printed on plain, fancy, surface colored,
or enammelled papers with suitable printed borders and devices, and by means of
mounting in various styles on wood pulp, straw, or paste-boards or zinc, tin and iron
plates, show cards and advertising tablets may be produced which will be thoroughly
waterproof and not affected by heat.
In carrying out my invention I obtain a sheet of glass free from blemishes and
after thoroughly cleansing I procure a quantity of gun cotton and dissolve in ether-
alcohol adding a little castor oil, when mixed I pour a thin film over the glass and
after allowing it to dry, a thin warm solution of gelatine is poured over the
cellulose surface.
When that has set for awhile I lay the sheet which may be surface colored or
enamelled paper, plain or printed, over the gelatine film and smooth it down, taking
care that no air bubbles arise between the gelatine and the paper. I then place to
dry in racks with a gentle heat for about 6 hours, I then glue or paste on, suitable
substance wood pulp, straw or paste-boards, or zinc, tin and iron plates and put
under pressure for a short time till they are well stuck down, then when the whole
is dry and the edges trimmed to separate the gelatine from the glass, the show
cards or tablets can be pulled off and a beautiful glass like surface of gelatine is
produced that is thoroughly waterproof and not affected by beat, and if dark
colored borders are printed with suitable devices in bronze or silver powders
around the sheet previous to gelatining, show cards and tablets are produced having
a similar effect to what is known as "crystoleum" show tablets.
Dated this 9th day of February 1894.

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
To manufacture waterproofed gelatine show bills, show cards, advertising tablets
or sheets, and the like, by a cellulose gelatine process, in the manner and for the
