I, WILLIAM PHILLIPS THOMPSON, F.C.S. M.I.M.E. of The Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool, and 6 Bank Street,
Manchester, both in the County of Lancaster, and 323 High Holborn in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this
invention to be as follows :-
This invention has for its object the protection of valuables against theft or
burglary, and consists essentially in surrounding the articles which are to be
protected with a wire netting in such a way that access can only be obtained to
such articles by removing or damaging this network, in either of which cases, an
electric bell, or other suitable electrical apparatus, arranged at a suitable place, is
caused to operate.
In the case of a door, a net made of insulated wires which run horizontally or
vertically is attached by means of hooks or clasps. This wire net, for practical
reasons and for the sake of appearance, is sewn between two pieces of cloth or
other suitable material, so that, from the outside, a door provided with such an
electrical net appears as if it were merely covered by an ordinary baize or other
curtain.
The wire netting employed forms, when attached to the door, or other place to
be protected, a continuous electric conductor, the current passing through the
netting and the fastening hooks or clasps, the latter being connected together by
conductors attached to the door post, so that the current is caused to traverse all
the wires in series.
The two poles or terminals of the protective network are provided with electric
conducting wires running to the electric battery and to a lever mechanism.
The moment the continuity of the electric conductor is interrupted, the electric bell
comes into operation owing to the end of a two-armied lever of the lever mechanism
which is held captive by means of an electro magnet so long as the continuity of
the conductor is not interrupted, being released when the electric current ceases,
and causing the other end of the lever to drop down and thus, by suitable contacts,
to connect the current with an electric bell or other alarm apparatus which is at
once operated.
In the case of a cash till or desk fitted with such a network, the netting is
placed at each side of the desk or till, the wires forming a continuous conductor by
means of the hooks or holders at the corners in the manner before described. For
greater security, this protective network may also be spread over the floor and
attached to the walls.
The protective netting may, in some cases, be also employed without the covering
of fabric hereinbefore mentioned, more particularly in cases where it is not desired to
conceal the articles which are to be protected, as, for instance, in the case of articles
exposed for sale.
It is, of course, understood that the wires need not cross one another at right
angles, on the contrary, they may be arranged in various positions, and the wires

page_text: may also be connected one with another at the places where they cross, as is
customary in fastening wire network.

An Improved Means for the Protection of Valuables against Theft or
Burglary.
A communication by GEORG KÁROLYI, of Buda Pesth, in the Empire of Austria,
Merchant.
I, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6 Lord Street, Liverpool and 6, Bank Street,
Manchester both in the County of Lancaster and 323 High Holborn in the
County of Middlesex, Civil Engineer, 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 has for its object the protection of valuables against theft or
burglary, and consists essentially in surrounding the articles which are to be
protected with a wire netting in such a way that access can only be obtained to
such articles by removing or damaging this network, in either of which cases, an
electric bell, or other suitable electrical apparatus, arranged at a suitable place, is
caused to operate.
On the accompanying drawing;
Figure 1 shows a door covered with the above mentioned network;
Figure 2 is a view in perspective of the arrangement of the network round a cash
desk or till.
In the case of a door, a net a bed made of insulated wires which run horizontally
or vertically is attached by means of hooks or clasps e e. This wire net for practical
reasons and for the sake of appearance, is sewn between two pieces of cloth or other
suitable material, so that, from the outside, a door provided with such an electrical
net appears as if it were merely covered by an ordinary baize or other curtain.
This cloth is not shown on the drawing for the sake of clearness and the wires are
shown only in dotted lines.
The wire netting employed forms, as shown on the drawing, when attached to
the door, or other place to be protected, a continuous electric conductor, the
current passing from the point f, through the netting and in turn through all the
fastening hooks or clasps e, the latter being connected together by conductors h
attached to the door post, so that the current is caused to traverse all the wires
in series.
The two poles or terminals f and ff of the protective network are provided
with electric conducting wires running to the electric battery I and to a lever
mechanism III.
The moment the continuity of the electric conductor is interrupted, the electric
-bell IV comes into operation owing to the end o of a two-armed lever of the lever
mechanism o which is held captive by means of an electro magnet A so long as
the continuity of the conductor is not interrupted, being released when the electric
current ceases, and causing the other end of the lever to drop down and thus, by
the parts B and C coming in contact, to connect the current through battery II
with an electric bell IV or other alarm apparatus which is at once operated.

In the case of a cash till or desk fitted with such a network as shown in Figure 2
the netting is placed on all sides of the desk or till, the wires forming a continuous
conductor by means of the hooks or holders at the corners in the manner before

page_text: described. For greater security, this protective network may also be spread over
the floor and attached to the walls.
.
The protective netting may, in some cases, be also employed without the covering
of fabric hereinbefore mentioned, more particularly in cases where it is not desired
to conceal the articles which are to be protected, as, for instance, in the case of
articles exposed for sale.
It is, of course, understood that the wires need not cross one another at right
angles, on the contrary, they may be arranged in various positions, and the wires
may also be connected one with another at the places where they cross, as is
customary in fastening wire network.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is :-
The improved means for the protection of valuables against theft or burglary
consisting essentially of a wire network connected with an electric battery, which
network, when hooked, screwed or otherwise suitably fastened over the place to be
protected, forms a continuous electric conductor, and which is connected in such a
way with a second electric battery that an electric bell, or other suitable alarm is
immediately set in action as soon as the electric current is interrupted in the
protective net substantially as described and shown on the accompanying drawing.
Dated this 26th day of September 1894.
