A Process for the Manufacture of Fuses, such as Firework Fuses, and
Apparatus in connection therewith.
I, CARL HUGO WOLF of 14 Burgstrasse, Zwickau, Saxony, in the Empire
of Germany, Inventor, 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 :-
The following invention relates to an expeditious and convenient mode of
producing fuses (especially for fireworks) of an exceedingly regular and uniform
character.
These advantages are obtained by a band or cord being wound in a spiral form
upon a frame or the like and the fluid fuse material laid thereon in the special
manner hereinafter described by means of a vessel provided with a small slit
therein.
If fuse points are desired to be put on both sides the band or cord is wound in
spiral form upon the side of a frame on pins placed at equal distances and by means
of horizontal cross bars turned round towards the one side or the other.
In order to facilitate the formation of the fuse points, at exactly uniform
distances on the long side of the frame, or of the trestle carrying the frame, pins or
guiding rods are placed at equal distances apart between which the holder of the
fuse material is placed.
The distance of these guide pins from one another is regulated by the desired
distance of the firing points.
And in order that my present invention may be easily understood and readily
carried into practice I will proceed to fully describe same with reference to the
accompanying drawings."
In the said accompanying drawings (representing an apparatus for the carrying
out of the process):-
Figure is a vertical section, and
Figure 2 is a horizontal section of such apparatus.
Figures 3 and 4 are horizontal sections through a modified apparatus for carrying
out my invention.
Figures 5 to 7 are detail views.
The band or cord a Figures 1 and 2 is wound round the pins hooks or pegs c
placed at equal distances along the small side (and from end to end) of the metal
or wood frame b and the strips a thus formed are held down horizontally by means
of the rods e fastened by means of bolts hooks clamps or screws & Figs. 1, 2, 6
and 7.
The hooks c must naturally lie so far apart from each other that the strips a
upon being laid round do not touch.
After the frame b so strung has been laid down and secured upon the trestle f
the receptacle g Figures 1, and 5 is filled with the fuse material and set in the
following manner between each two of the pins i (set equi-distant apart) placed
down cach side (ie. the long side) of the trestle.
The fuse material then passes (or is caused to pass) through a small slit in the
lower part of the receptacle g on to the strips a.
When the whole length of the strips are thus treated upon one side the frame b
is lifted from the trestlef turned over and set down again and treated in above
described manner upon the other side.
If only one side of the strips is to be thus treated the band is simply wound flat
upon the frame b (Figs. 3 and 4) the narrow side of which for the facilitating of a
uniform winding can also be provided with pins c.

page_text: After thus being treated and prepared the strips are placed with the frame in a
drying room and after perfect drying overlaid with paraffin wax or other suitable
material by being drawn through the melted mass; and for the uniform distribution
of the latter may be allowed to pass through soft pads of india rubber leather or
other suitable material.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is
1. A process for making fuses such as firework fuses consisting of winding a cord
in spiral form upon a frame or other suitable contrivance and laying the fluid fuse
material simultaneously upon the whole of the strips running parallel to each other
at the desired distances apart and thereafter suitably dried and finished substantially
as and for the purposes set forth.
2. I claim the modification of the process claimed above-consisting of winding
the band or cord in spiral form round pins hooks or pegs placed at uniform
distances apart upon the short side of the frame and held down horizontally by
means of cross bars for the purpose of facilitating the laying on of the fuse material
on both sides of the strips (by the turning round of the frame) and afterward
drying and finishing in a suitable manner substantially as and for the purposes
hereinbefore set forth.
3. With the contrivances for the carrying out of the process claimed in Claims 1
and 2-the arrangement of equi-distant pins upon the long side of the frame or
trestle carrying the frame in order to render possible by the successive setting of
the fuse material holder between the separate pins the laying on of the fuse points
at exactly equal distances substantially in the manner and for the purposes herein-
before described and illustrated by way of example in the drawings hereunto
annexed.
