PROVISIONAL SPECIFICATION.
Improvements in Playing-cards.
I, SIEGMUND NEUGRÖSCHL of No. 3 Ferdinandsgasse, Brünn, in the Empire
of Germany, Commercial Traveller, do hereby declare the nature of this invention
to be as follows:-
It is well known that the usual card-board playing cards wear out in a very short
time especially at the corners, and are apt to split or come apart into sheets, to
be readily marked with the finger nails, and by absorbing grease and dirt to
become very unsightly through use.
The object of this invention is to remedy all these defects by making the cards
of celluloid, a certain quantity of asbestos being added to the celluloid in the
process of manufacture to make it more fire-proof than it would otherwise be.
The cellulose is treated with acids in the well-known manner, so as to obtain
nitro-cellulose to which, besides camphor, a small percentage of asbestos fibres is
added.
The mass is well mixed and then made into sheets between suitable rollers.
These sheets are then cut into cards of the required size and the cards may be
painted or otherwise coloured at the back to render them opaque.
The front surfaces receive the ordinary playing cards pictures and devices.

Improvements in Playing-cards.
I, SIEGMUND NEUGRÖSCHL of No. 3 Ferdinandsgasse, Brünn, in the Empire
of Germany, Commercial Traveller, 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 :-
It is well-known that the usual card-board playing cards wear out in a very short
time especially at the corners, and are apt to split or come apart into sheets, to be
readily marked with the finger nails, and by absorbing grease and dirt to become
very unsightly through use.
The object of this invention is to remedy all these defects by making the cards
of celluloid, a certain quantity of asbestos being added to the celluloid in the
process of manufacture to make it more fireproof than it would otherwise be.
The cellulose is treated with acids in the well-known manner, so as to obtain
nitro-cellulose to which, besides camphor, a small percentage of asbestos fibres is
added.
The mass is well mixed and then made into sheets between suitable rollers.
These sheets are then cut into cards of the required size and the cards may be
painted or otherwise coloured at the back to render them opaque.
The front surfaces receive the ordinary playing card pictures and devices.
If preferred other material than celluloid, but similar to the latter, (for example
what is known as celluvert or the like) might be used; or celluloid, celluvert, etc.,
might be combined with other substances or materials; for example sheets of
paper, cardboard, thin metal sheets, or the like might be covered on one or both
sides with celluloid and kindred substances; the cards retaining nevertheless the
appearance of being made of celluloid or analogous material throughout.

page_text: 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 :-
1. Playing cards made of sheets of celluloid to which in the course of manu-
facture asbestos is added for the purpose of making the cards incombustible.
2. Playing cards consisting of plates or sheets of celluloid painted at the back
to avoid transparency while the front surface is provided with the usual playing-
card figures by printing or any other suitable manner.
3. Playing cards made either of celluloid or kindred fibrous material throughout
cr of such material in combination with other substances or materials, the celluloid
or the like being if necessary applied only as an external coating.
