Improvements in Signals or Alarms for the Protection of Property
from Trespassers and the like.
WALTER BAILY, Gun and Trap Manufacturer, Malvern-Wells, Worcestershire,
do hereby declare the nature of this invention to be as follows:-
-
In order to more clearly describe this invention, a sheet of drawings is sent
herewith. The apparatus consists of a block of metal A Fig. 2 in which is a
square hole which slides upon a vertical square rod B Fig. I the side C of the
block acting as a weight. The top of the rod B is hollow to contain a fuse D,
the top of which is covered by a waterproof preparation easily ignited by friction.
The slot K allows the empty fuse end to be removed without difficulty. Attached
to the block by a hinge is a metal cap or shield E which fits over the top of the
block, at the top of and on one side of the square hole of the block, is a raised
metal band Funder which is placed a small slip of card covered with an igniting
composition. To set the detective light, the fuse 1) is placed in the hollow of
the rod, the igniting card is pushed under the band and the block A placed
on the rod B and kept in an elevated position by a wedge G which enters a
niche H in the side of the rod, the cap E is then turned over the top of the
block. One or more wires are attached to the wedge G, and when a trespasser
comes in contact with the wire the wedge is dislodged, the block falls throwing
back the cap E, the fuse D is ignited by rubbing against the friction card and
burns for a brilliant white light for a minute.
By placing an alarm gun lower down the rod, the weighted part of the block
will fall on the striker of the alarm gun, and thus by the same movement the
fuse is ignited and the gun fired.
Dated this 8th day of March 1800.

I, WALTER BAILY, Gun and Trap Manufacturer, Malvern-Wells, Worcester-
shire, 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 apparatus consists of a block of metal A Fig. 2 (drawings of which were
left with the Provisional Specification) in which is a square hole which slides

page_text: on a vertical square rod B Fig. 1 the side C of the block acting as a weight. The
top of the rod B is hollow to contain a fuse 1), the top of which is covered by
any preparation easily ignited by friction. The slot K allows the empty fuse
end to be removed without difficulty. Attached to the block by a hinge is a
metal cap or shield E which fits over the top of the block. At the top and on
one side of the square hole of the block, is a raised metal band F under which
is placed a small slip of card covered with an igniting composition. To set the
detective light, the fuse 1) is placed in the hollow of the rod, the igniting card is
placed under the band F, and the block A placed on the rod B, and kept in
an elevated position by a wedge G which enters a niche H at the side of the
rod, the cap E is then turned over the side of the block. One or more wires are
attached to the wedge G, and when a trespasser comes in contact with the wire,
the wedge is dislodged, the block falls throwing back the cap E, the fuse Dis
ignited by rubbing against the friction card, and burns giving a brilliant white
light for a minute. By placing an alarm gun lower down the rod, the weighted
part of the block will fall on the striker of the alarm gun, and thus by the same
movement, the. fuse is ignited and the gun fired.
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:
-
The combination of the various parts of the apparatus for firing detective
lights in connection with alarm guns.
Dated this 19th day of August 1899.
