PROVISIONAL SPECIFICATION.
Improvements in Fireworks.
I, CHARLES HUELSER of the firm of Huelser & Co. of Temple Chambers,
London, International Patent Agency, do hereby declare the nature of this
invention, a communication to me from abroad by Gustav Gillischewsky, of
Müllerstrasse, Berlin N., in the Empire of Germany, Manufacturer, to be as
follows:-
This invention has for its object to produce a liquid mass, which can be put on
wood pins in a similar manner as the mass for Bengal lights, so that matches are
obtained, by the burning of which so-called star-fire-work is produced, which was
hitherto made by pulverous preparations that had to be enclosed in tubular
receptacles.
The improved process is essentially as follows:
12 units of steel chips are put into a solution of stearine and benzine. After the
liquid has been shaken off, the dry chips remain covered with a thin layer of
stearine which protects them from rust. 96 units of nitrate of lead and 12 units of
charcoal are thoroughly mixed in a finely powdered state with the steel chips
treated as described above, and subsequently the whole mixture is brought into a
concentrated solution of shell-lac and spirits. Thereby a liquid is produced, into
which wood pieces placed into a frame in the same manner as in the process for
dipping matches, are deeply dipped, so that a thick tubular coating adheres. After
drying, an igniting head as that of ordinary matches is dipped to the end of the
coated portion of the wood pieces.
Dated this 26th day of October 1891.

COMPLETE SPECIFICATION.
Improvements in Fireworks.
I, CHARLES HUELSER, Patent Agent, of Temple Chambers, Temple Avenue,
in the City of London, 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 :-
Hitherto it has been usual, to produce star fireworks from mixtures or
compositions in the shape of powder, which had to be enclosed in tubular
receptacles.
This invention has for its object, to produce a liquid mass, which can be applied
to wooden pins or sticks in a similar manner as the mass for Bengal lights, so that
matches are obtained, by the burning of which so-called star fireworks may be
produced.
Fer this purpose, 12 units of steel chips are put into a solution of stearine and
benzine. After the liquid has been decanted, the dry chips remain covered with a
thin layer of stearine which protects them from rust. 96 units of nitrate of lead
and 12 units of charcoal are now thoroughly mixed, in a finely powdered condition,
with the steel chips treated as described above, and subsequently the whole mixture
is brought into a concentrated solution of shellac in spirits. Into the (more or less)
liquid mass thus produced are dipped pieces of wood which have been placed into a
frame in the same manner as in the process for dipping matches. The said pieces
are dipped deeply, so that a thick tubular coating adheres. After drying, an

page_text: igniting head as that of ordinary matches is dipped on to the end of the coated
portion of the wood pieces.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
1. The manufacture of a liquid mass for star fireworks by introducing a mixture
of 96 parts of lead nitrate, 12 parts of charcoal and 12 parts of stearine-coated
steel-chips into an alcoholic solution of shellac, substantially as described.
2. Matches which have been dipped into a liquid or viscous mass suitable for
producing star fireworks, substantially as described.
