Improvements in or relating to Illuminating Projectiles.
I, TITO TOCCACELI, Manufacturer, of Via Napoli 24, Rome, Kingdom of Italy,
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 present invention relates to the manufacture of illuminating projectiles,
especially applicable for use in warfare for lighting up or ascertaining the position
of an enemy.
In the accompanying drawing,
Figure 1 represents the projectile body in section, while
Figures 2, 3, 4, 5 and 6 show various parts of the projectile, and
Figure 7 a charged projectile.
In Figure 1, A is the projectile casing provided in its inner side with a
groove from top to bottom intended to receive a tube B or the like forming a
communication between the top and bottom of the projectile. C represents a
diaphragm arranged in the interior near the bottom. D is the rear piece or
plug of the projectile, below the diaphragm, and screwed into the casing. E is
a recess in the rear piece, and F is an opening into which a time fuse is screwed,
as used in artillery.
Figure 2 represents the diaphragm C, separated from the case, provided with
communication holes G. It may also be provided with a handle H, and two
lateral projections I opposite to each other, which lock in the walls of the
casing, and with a diagonal or inclined groove 'K which serves as á means of
communication between the small tube B and the recess E in the rear piece D.
Figure 3 represents the rear piece D separated from the casing. E is the
recess or reservoir, L represents the screw thread by means of which the rear
piece is connected with the casing A.
Figure 4 represents a case M, cylindrical by way of example, but which may
be of any other shape or form, and which contains the illuminating substance
for instance a mixture of magnesium, barium nitrate and sulphur, at one end
and at 'the other is provided with a parachute. When these objects are in
action they pass out of the case M, but always remain connected. The ends
of this case are closed with gummed paper and bound with a wick or "touch"
paper N or any like means for facilitating burning or ignition, although it
will work also without it.
Figure 5 represents a case 0 made of metal or of any other suitable material
and of any suitable shape or form, provided with a communication fuse on its
surface, which case is filled with the cylinders M. This case is then enveloped
in some fabric or other material as represented by P in Figure 6.
Figure 7 finally, represents the projectile with its charge Q. similar in every
respect to Figure 6, a space R being reserved for deadening material. To
complete the charge a time fuse is placed in F and a fuse is placed in the
tube B passing also through the diagonal groove K of the diaphragm, Figure 2.
The reservoir E is provided with charge of powder.

page_text: 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 projectile comprising the following parts: an outer casing A, a tube
leading from the head of the projectile to the rear piece, a diaphragm, a rear
piece provided with a recess and secured to the casing substantially as described.
2. A case of any suitable shape provided at one end with illuminating material
and at the other with a parachute substantially as described.
3. A charge for an illuminating, projectile comprising a vessel made of metal
or other suitable 'material containing one or more cases such as M substantially
as described.
4. A charge for an illuminating projectile comprising a vessel 'containing
one or more cases as M and an outer cover for the vessel made of tissue or of
any other convenient material substantially as described.
5. A projectile of the kind described laying in its interior a charge of illuminat-
ing material and a space for deadening material substantially as described.
6. The complete 'illuminating projectile substantially as described or illus-
trated in the accompanying drawings.
Dated this 14th day of September 1899.
