PROVISIONAL SPECIFICATION.
Improvements in Pyrotechnic Signals.
THOMAS WILLIAM HAND and WALTER TEALE, both of the City of Hamilton,
Ontario, Canada, Pyrotechnists, do hereby declare the nature of this invention to
be as follows:-
Our invention consists of a rocket igniting light, loaded, and to which is attached
a fuse of suitable length to carry and light a series of smaller lights, which are
also loaded with combustible matter.
This series of lights are attached at their other ends by a connecting line of
asbestos or fireproof cord, flexible chain or links which hold the lights in position
when the fuse has ignited them and expended itself. These lights burn and send
forth a certain colored light, and are arranged for the purposes of signal service.
The aforesaid cord or chain besides being attached to the said series of lights,
has its lower end firmly secured to the igniting light, and at the other end
separates into a number of strands attached to a parachute; our objects being to
provide a series of colored lights arranged in proper position and order, and ignited
with one rocket power; and also to afford facilities for suspending the same in
the air, or where required for signal service.
In the drawing
Figure 1 is an elevation of the signal apparatus with a series of lights all con-
nected consecutively by means of a fuse, and the connecting line of non-ignitible
material, the upper end of said line being attached to a parachute of flexible
material and construction.

match, B, of suitable length to be attached to and light any number of shells or

D is the asbestos or non-ignitible connecting line, connecting the said shells or
lights, C, and the igniting shell or light, A, so that when the fuse, B, is exhausted,
the said lights are still held in their proper position and order of color for the
desired signal.
This connecting line, D, separates at its upper end, into strands, d, which
support a flexible fabric parachute, E. e is an elastic strand extending from the
line, D, to the centre of the parachute, E.

rocket, H, its conical cover, I, to fit snugly to the upper part of said rocket, H,
and holds and retains compactly the signal apparatus when folded together.
The rocket fuse, J, communicates power to the said rocket, and the rod, K, is
to steady the said rocket.
M is a gun or mortar shell which will also contain our signal apparatus, and
may at certain times be more convenient for signal purposes than the rocket,
either of which will give the necessary force and power.

COMPLETE SPECIFICATION.
Improvements in Pyrotechnic Signals.
We, THOMAS WILLIAM HAND and WALTER TEALE, both of the City of
Hamilton, in the County of Wentworth, in the Province of Ontario, Dominion of
Canada, Pyrotechnists, 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 :-
Our invention relates to improvements in pyrotechnic signals, and consists of a
rocket igniting light, loaded or charged, and to which is attached a fuse of suitable
length to carry and light a series of smaller lights, which are also loaded with
combustible matter.
This series of lights are attached at their other ends by a connecting line of
asbestos or fire-proof cord, flexible chain or links, which holds the lights in position
when the fuse has ignited them, and expended itself.
These lights burn and end forth a certain colored light, and are arranged for
the purposes of signal service.
The aforesaid cord or chain, besides being attached to the said series of lights,
has its lower end firmly secured to the igniting light, and at the other end,
separates into a series of strands, attached to a parachute; and the objects of our
improvements are, first, to provide a series of colored lights arranged in proper
position and order, and ignited with one rocket power; and, second, to afford
facilities for the suspending of the same in the air, or where required for signal
service.
We attain these objects by the device illustrated in the drawing left with the
Provisional Specification, in which:
Figure 1 is an elevation of the signal apparatus, with a series of lights all
connected consecutively by means of the fuse and the connecting line of non-
ignitible material, the upper end of said line being attached to a parachute of
flexible material and construction.
Figure 2 is an elevation of a rocket of smaller scale, its upper part in section,
with its cover detached, also in section, showing the position of the lower igniting
light (Fig. 1) in its interior, said interior with its said cover, to contain the whole
of the signal apparatus, when carefully folded together and placed therein.
Figure 3 is an elevation of a gun or mortar shell, its upper part in section, in
which this signal apparatus may also be placed.
Similar letters refer to similar parts throughout the several views:
A is the igniting light of a signal rocket, to which is attached a fuse or quick
match, B, of suitable length to be attached to and light any number of shells or
lights, C, containing different colored lights, and arranged in such a manner and
order to suit the requirements of signal service.
D is the asbestos or non-ignitible connecting line, connecting the said shells, or
lights, C, and the igniting shell or light, A, so that when the fuse, B, is exhausted,
the lights are still held in their proper position and order of color, for the desired
signal.
This connecting, D, separates, at its upper end, into strands, d, which support a
flexible fabric parachute, E. e is an elastic strand, extending from the line, D,

page_text: to the centre of the parachute, E. This device is delineated, and, as shown in
Fig 1, forms the essential elements in our invention.
In Figure 2 is shown the igniting light, A, broken from its attached fuse, and
connecting, in position with its wad, a, fitting in the lower part of the upper
chamber of the rocket, H. The cover, I, fits snugly to the upper part of said
rocket, H, and holds and retains compactly the whole of the apparatus, when
folded, as shown in Fig. 1.
The rocket fuse, J, communicates power to the lower part of said rocket, and
the rod, K, is for steadying purposes.
M is a gun or mortar shell, which will also contain our invention in its upper
part, and may at certain times, be more convenient for signal purposes, than the
rocket, either of which will give the necessary force and power.
The igniting light, A, which is of greater power than the colored lights, C, is
also for the purpose of first drawing attention to the coming signal, and in turn,
giving power to the colored lights, by means of its fuse.
The elastic, e, holds the centre, e, of the parachute in position, to ensure the
even inflation of the whole.
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:
1st. In a pyrotechnic signal, the combination of an igniting light, A, with its
wad, a, and its attached fuse, B, which is also attached to a series of colored
lights, C, substantially as set forth and specified.
2nd. In a pyrotechnic signal, an igniting light, A, and its fuse, B, with the
colored lights, C, in combination with the non-ignitible connecting line, D,
substantially as set forth and described.
3rd. In a pyrotechnic signal the combination of the igniting light, A, colored
lights, C, fuse B, connecting line, D, and a parachute, E, with its strands, d, and
its centre, e', substantially as set forth and described.
4th. The rocket, H, having widened top, with its close-fitting conical cover, I,
forming a chamber containing and enclosing the igniting light and wad, the flexible
fuse, the colored lights, the flexible and non-ignitible connecting line and fabrical
parachute, with fuse, J, attached to lower part of said rocket, H, giving power to
the whole, substantially as described and set forth.
