PROVISIONAL SPECIFICATION.
Improved Means for Identifying Poachers and other Trespassers.
I JOHN NASH of Dinmore Hill near Leominster in the County of Hereford,
Gamekeeper, do hereby declare the nature of this invention to be as follows:--
The object of this invention is a means whereby poachers and other trespassers
may be detected and consists of an appliance whereby a material such as tar for
example is automatically thrown over the poacher or other trespassers. One way
of carrying out this invention is by means of an appliance constructed and arranged
substantially as follows.
On to a flat piece of wood I fit a spring hinged arm and to the end of said arm I
fix a cup and connected with the aforesaid spring hinge is a chain or cord to
prevent the aforesaid arm from moving further than in a perpendicular position
when the appliance goes off as hereafter described.
The aforesaid arm is held down by means of a catch and in connection with said
catch is a length of wire so arranged that when it is touched the aforesaid arın will
be released from the catch and the arm and cup will fly up and thus throw the
contents (with which the cup has been previously charged which may be tar or
other suitable material) in the direction of the wire and consequently over the
poacher or other trespasser by which he may be detected.

COMPLETE SPECIFICATION.
Improved Means for Identifying Poachers and other Trespassers.
I JOHN NASH of Dinmore Hill near Leominster in the County of Hereford,
Gamekeeper, 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 object of this invention is a means whereby poachers and other trespassers
may be detected and consists of an appliance whereby a material such as tar for
example is automatically thrown over the poacher or other trespassers.
One way of carrying out this invention is by means of an appliance constructed
and arranged substantially as follows.
On to a flat piece of wood I fit a spring hinged arm and to the end of said arm I
fix a cup and connected with the aforesaid spring hinge is a chain or cord to
prevent the aforesaid arm from moving further than in a perpendicular position
when the appliance goes off as hereafter described.
The aforesaid arm is held down by means of a catch and in connection with said
catch is a length of wire so arranged that when it is touched the aforesaid arm will
be released from the catch and the arm and cup will fly up and thus throw the
contents (with which the cup has been previously charged which may be tar or
other suitable material) in the direction of the wire and consequently over the
poacher or other trespasser by which he may be detected.
And in order that my said invention may be better understood I will describe the
same with reference to the accompanying sheet of drawings in which :—
Fig. 1, shews side elevation of an apparatus constructed according to this
invention.

page_text: Fig. 2, top plan of same with case m. removed.
Fig. 3, view partly in section through line A B Fig. 2, this figure is drawn to
an enlarged scale.
The same letters denote the same parts in all the views:-
a shews arm one end of which is fixed to convolute spring b. this latter is covered
by a case m, to the other end of arm a. is fixed cup c. d is a catch lever pivotted
at e. to bracket f. g is a pivotted catch. is a chain one end of which is connected
to base plate i. is a hook connected to base plate i. is a wire fixed at one end
to the catch lever d.
The action is as follows.
The apparatus being placed (or preferably fixed on the ground) in the direction
where it is supposed poachers or other persons are likely to come the cup c is
charged with tar or other suitable material and the arma is held down horizontally
by the catch g. passing over it and being held by the tooth n. in lever d. taking
over the end of catch y. when this lever d. is in the position shewn dotted at Fig. 1.
the wire is then carried along the ground and may be fixed thereto at its free end
by means of a short stake driven in the ground so that when a poacher or other
person touches the wire l. it will pull the arm d. slightly forward and thus release
the catch g. and the arm a will Hy up as far as the chain h. will allow it and thus
throw the tar or other material in the direction of the wire l. and consequently over
the poacher or other person trespassing.
The hook is simply for hooking over the arm d when it is not desired that the
apparatus shall go off.
By the above means the poacher or other trespasser can easily be identified by
the tar or other material (discharged over him) being on his clothes.
A spring gun could also be fitted to this apparatus the one working in conjunction
with the other.
The apparatus could be set in buildings warehouses and other places as burglars
on entering such buildings on receiving a shower of tar or paint would surprise
them very much and doubtless they would leave the buildings at once.
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: :―
The means for identifying poachers and other trespassers substantially as
described and shewn on the drawings.
