PROVISIONAL. SPECIFICATION.
Improved Means for Detecting Poachers or other Trespassers.
We, GEORGE PINDER, of Edwinstowe, near Newark, Nottinghamshire, Fire-
work Manufacturer, and GEORGE FORD of Edwinstowe, aforesaid, Firework
Manufacturer's Foreman, do hereby declare the nature of this invention to be as
follows:-
This invention consists of the hereindescribed improved means for detecting at
night poachers burglars or other trespassers.
At the present time it is a common thing for game keepers to carry what are
called identifiers which are fireworks something like Bengal lights and which serve
as signal lights and which the game keepers light on an alarm being given so as to
signal to their comrades and identify the poachers.
Now according to this invention we so arrange the firework, signal light, or signal
lights, that it or they can be fixed in any convenient place where a poacher burglar
or other trespasser is likely to come, so that the fact of a poacher, burglar, or other
trespasser coming in contact with the signal light or signal lights, or within. a
certain distance of the same so as to come in contact with a string wire or other
connection which as hereinafter described is attached to the signal light or signal
lights, would cause such signal light or signal lights to be ignited and thus expose
the poacher, burglar, or other trespasser to view. We may use the said signal light
or signal lights arranged in this way either by itself or by themselves or in com-
bination with an alarm gun which is caused to go off by the poacher burglar or
other trespasser coming in contact with it or with a string or wire attached to the
gun. Or we may arrange our improved signal light or signal lights in combination
with a maroon which would go off at the same time and cause a loud report.
In order to cause the act of a poacher, burglar, or other trespasser coming in
contact with or in the neighbourhood of a signal light or signal lights arrange l
according to my invention to light such light or lights we fix the signal light or
signal lights on the ground, or on a tree, or other suitable support, and provide it
or them with a string wire or other. connection which is carried across or partly
across the road or other part where the trespassers are likely to come so that when
the trespasser kicks or disturbs the string wire or other connection this acts upon
the friction al part of the identifier or releases a spring or hammer which strikes
upon a cap or by other means effects the ignition of the signal light or signal lights
and at the same time as stated above this may also fire an alarm gun or a maroon
which maroon if desired may also form a part of the signal light.
Or the string wire or other connection above stated may be connected directly
to the alarm gun as is usual at the present time and this alarm gun may when fired
also be arranged to ignite the signal light or signal lights.

We, GEORGE PINDER, of Edwinstowe, Newark, Nottinghamshire, Firework
Manufacturer, and GEORGE FORD, of Edwinstowe, aforesaid, Firework Manu-
facturer's Foreınan, 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:-
This invention consists of the hereindescribed improved means for detecting at
night poachers burglars or other trespassers.
At the present time it is a common thing for game keepers to carry what are
called identifiers which are fireworks something like Bengal lights and which serve
as signal lights and which the game keepers light on an alarm being given so as to
signal to their comrades and identify the poachers.
Now according to this invention we so arrange the firework, signal light, or signal
lights, that it or they can be fixed in any convenient place where a poacher or
burglar or other trespasser is likely to come, so that the fact of a poacher, burglar,
or other trespasser coming in contact with the signal light or signal lights, or within
a certain distance of the same so as to come in contact with a string wire or other
connection which as hereinafter described is attached to the signal light or signal
lights, would cause such signal light or signal lights to be ignited and thus expose
the poacher, burglar, or other trespasser to view. We may use the said signal light.
or signal lights arranged in this way either by itself or by themselves or in com-
bination with an alarm gun which is caused to go off by the poacher burglar or
other trespasser coming in contact with it or with a string or wire attached to the
gun. Or we may arrange our improved signal light or signal lights in combination
with a maroon which would go off at the same time and cause a loud report.
In order to cause the act of a poacher burglar or other trespasser coming in
contact with or in the neighbourhood of a signal light or signal lights arranged
according to our invention to light such light or lights, we fix the signal light or
signal lights on the ground, or on a tree, or other suitable support, and provide it
or them with a string wire or other connection which is carried across or partly
across the road or other part where the trespassers are likely to come so that when
the trespasser kicks or disturbs the string wire or other connection this acts upon
the frictional part of the identifier or releases a spring or hammer which strikes
upon a cap or by other means effects the ignition of the signal light or signal
lights and at the same time as stated above this may also fire an alarm gun or a
maroon which maroon if desired may also form a part of the signal light.
Or the string wire or other connection above stated may be connected directly to
the alarm gun as is usual at the present tine and this alarm gun may when fired also
be arranged to ignite the signal light or signal lights.
On the accompanying drawing Fig. 1 shews our invention as set ready for the
poacher or other trespasser to fire the signal light and maroon or report and Fig. 2
shews separately parily in section the form of signal light which we may use. As
the string wire cr cord in Fig. 1 is of considerable length this figure is shewn broken
off in the centre so as to quable both ends to be shewn on the drawing.
The same letters of reference indicate the same or corresponding parts in both
figures.
A is the signal light fixed to the post B by any convenient means as by the
spigot end being placed in the hole in the post B and secured by the binding
screw c. The composition in this signal light A is similar to that used in the well-
known identifiers or signal lights used by gamekeepers. D is one of the frictional
parts (covered with say a preparation of amorphous phosphorus) connected to the

page_text: string E and carried by the loop f in the removable cap F. The loop f and the
end a² of the signal light are covered with the other frictional part of the igniting
composition usually chlorate of potass and antimony or other ingredient as well
known. G is the maroon consisting of an outer case filled with an explosive
composition which will give a loud report when fired this maroon G being fixed to:
the post B by fitting in a hole therein and there secured by the binding screw
similarly as is the signal light A. This maroon or report G is also arranged to be fired
by a removable frictional part attached to the string H similarly as above described
with reference to the signal light A. The strings Ę and H are both attached to.
the weight I which is threaded on the guide rod J so as to move very freely thereon
this guide rod J being fixed to the post B. L is a peg which can be passed through
a hole in the guide bar so as to support the weight I in its raised position shewn by
Fig. 1. M is the string or wire which by a swivel hook m. or by other means is.
connected to the peg L and is carried across or partly across the rod or other part.
where the trespassers are likely to come the other end of the string or wire M being
fixed to a post N or to a tree or rail or other convenient part so that the wire or
string M will be moderately taut.
Assuming that the apparatus is set as shewn in Fig. 1 with the strings E and H
of the frictional parts of the signal light A and maroon G attached to the falling
weight I and this latter supported by the peg L connected to the wire or string M
than when the trespasser kicks or otherwise disturbs the string or wire M this will
pull the peg L out of its hole in the guide bar J and as the weight I being then
unsupported will fall and snatch the strings E and H so that the frictional parts of
the signal light A and of the maroon or report G will be suddenly drawn across.
the other part of the igniting composition and the signal light A. and the maroon G
will be fired simultaneously the latter causing a loud report and the former a bright.
signal light which will burn for several minutes and enable the poachers or
trespassers to be identified.
The accompanying drawing illustrates what we consider to be the best way of
carrying our invention into practice but it is to be understood that our invention is
not lunited to the precise arrangement shewn upon the drawing as for instance the
moving frictional parts which are attached to the strings E and H night as in other
signal lights and fireworks be connected directly to the signal light A or maroon G
instead of being attached to a cap which fits upon the same. Also other methods
of fixing the signal light and maroon to the post might be adopted. Also we may
use one or more additional signal lights with the light A each arranged with a
string connected to the weight I so as to be fired simultaneously by the falling of
the saine; moreover if desired the maroon or report G may be dispensed with and
the appliance used to fire the oue or more signal lights A only.
Having now particularly described and uscertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In an apparatus for detecting poachers or other trespassers the employment of
a signal light adapted to be fixed to the ground or to a tree, post or other support,
said signal light having frictional parts for igniting the same, one of said frictional
parts being provided with a string, cord or wire by which the said movable
frictional part can be drawn across the other frictional part and thus ignite the
signal light, substantially as described.
2. In an apparatus for detecting poachers or other trespassers, the combination of
a signal light adapted to be fixed to a tree post or other support and provided with
frictional parts one of which is movable for igniting the same, a weight attached to.
or adapted to be attached to said movable frictional part by a string cord, wire or the
like, means for supporting said weight and for releasing the same by the pull of a
string cord wire or the like so as to pull the movable frictional part across the other
frictional part and ignite the signal light, substantially as hereinbefore set forth.
3. Apparatus lor detecting poachers and other trespassers constructed arranged

page_text: and operating substantially as herein before set forth with reference to the
accompanying drawing.
4. In an apparatus for detecting poachers or other trespassers the combination of
a signal light and a maroon or report both adapted to be fixed to a tree post or
other support and both provided with frictional parts for igniting the same, a weight
attached to or adapted to be attached to said movable frictional parts by a string
cord wire or the like, means for supporting said weight and for releasing the same
by the pull of a string cord wire or the like so as to pull the movable frictional
parts across the other frictional parts and ignite both the signal light and the
maroon or report simultaneously substantially as herein before set forth.
5. In apparatus for detecting poachere or other trespassers the combination of
the signal light A and maroon or report G both adapted to be fixed to the post B
and both made with frictional parts attached to strings for igniting the same, the
post B for supporting the signal light and maroon or report and made with a guide
or support for the firing weight, the weight I guided by the support J and
adapted to be connected to the strings cords wires or the like of the said frictional
parts, the peg L for supporting the weight M connected to said peg for releasing
the weight to pull the frictional parts and fire the signal light and maroon
simultaneously, substantially as hereinbefore set forth.
6. An apparatus for detecting poachers and other trespassers in which a signal
light and a maroon or report are suitably supported and are arranged to be fired
simultaneously by the pull of a string cord or wire releasing a weight which in
falling draws the movable frictional parts of the signal light and maroon or report
across the fixed frictional parts of the same all substantially as hereinbefore set
forth.
