IMPROVEMENTS IN ALARM SIGNALS FOR DOMESTIC AND OTHER PURPOSES
Year: 1884

page_text: I, JOSEPH MARSHALL of Salter Gate, Chesterfield in the County of Derby,
Wholesale Yeast, Egg and Butter Merchant do hereby declare the nature of my said
invention for "IMPROVEMENTS IN ALARM SIGNALS FOR DOMESTIC AND OTHER
PURPOSES" to be as follows:-
The object of this my Invention is to signal the approach of housebreakers,
thieves, burglars, poachers and the like and at the same time to afford a simple and
effective protection against them.
To this effect I place an upright pillar or rod on a suitable base or pedestal in
such a manner that the rod and pedestal may be moved from place to place when
desired or the rod may be attached to the floor or fixed in the ground. At a short
distance from the bottom of the said rod, which may be made of wood, metal or
other suitable material I attach a chamber or barrel to contain percussion caps;
cartridge or gun. Around the pillar aforesaid put a heavy ball or weight with
an aperture which allows the said ball or weight to be moved up and down the
pillar at will. Near the top of the Pillar I make a notch into which a peg fits
sufficiently strong for the weight to rest upon. To the peg aforesaid I attach one
end of a thin cord or stout thread and stretch the same across the window, door,
gate or footpath to be protected and I fasten the other end of the cord or thread
aforesaid to any support which may be convenient. When it is desired to set my
alarm signal I place a percussion cap or cartridge on or in the barrel aforesaid so
as to come in contact with the weight when it falls. I then draw the heavy ball
or weight up the rod beyond the notch and having inserted the peg allow the said
weight to rest upon the peg to which one end of the cord has been previously
attached, the other end of the cord being fixed to a convenient support. Any
person now coming in contact with the cord (which is not perceptible at dusk) will
cause the peg to be withdrawn, the heavy ball or weight immediately falls and
fires the percussion cap, gun or cartridge and alarms the residents warning them
of approaching danger. When the "Alarm" is placed out of doors a pin fire
cartridge may be used and the barrel will protect it from all wet.

page_text: I, JOSEPH MARSHALL, of Salter Gate, Chesterfield, in the County of Derby,
Wholesale Yeast, Egg, and Butter Merchant, do hereby declare the nature of my
said Invention for "IMPROVEMENTS IN ALARM SIGNALS FOR DOMESTIC AND OTHER
PURPOSES," and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement, reference being had
to the accompanying drawings and to the letters of reference marked thereon, that
is to say-
The object of this my Invention is to signal the approach of housebreakers,
thieves, burglars, poachers, and the like; and at the same time to afford a simple
and effective protection against them.
To this effect I place an upright pillar, or rod A, on a suitable base, or pedestal B,
in such a manner that the rod A, and pedestal B, may be moved from place to
place when desired; or the same may be attached to the floor; or, by dispensing
with the pedestal the rod itself will form a spike, and may be fixed in the ground.
At a short distance from the bottom of aforesaid rod A, which may be of wood,
metal, or other suitable material, I attach a chamber or barrel to contain percussion
caps, cartridge, or gun. Around the pillar. A aforesaid, I put a heavy ball, or
weight D with an aperture which allows the said ball, or weight D to be moved
up and down the pillar, or rod A, at will. Near the top of the pillar, or rod A,
I make a notch E, into which a peg F fits, sufficiently strong for the weight D to
rest upon. To the peg F aforesaid, I attach one end of a thin cord, or stout
thread, G, and stretch the same across the window, door, gate, or footpath, to be
protected, and I fasten the other end of the cord, or thread G, aforesaid to any
support which may be convenient.
When it is desired to set my alarm signal, I place a percussion cap, or cartridge
on, or in the barrel C aforesaid, so as to come in contact with the weight when it
falls. I then draw the heavy ball or weight D up the rod, or pillar A, beyond the
notch E, and having inserted the peg F, allow the said weight D to rest upon the
peg F to which one end of the cord G has been previously attached, the other end
of the cord being fixed to a convenient support. Any person now coming in
contact with the cord (which is not perceptible at dusk, or in the dark) will cause.
the peg F to be withdrawn, the heavy ball; or weight D, immediately falls, and
fires the percussion cap, gun, or cartridge, and alarms the residents, warning them
of approaching danger. When the alarm is placed out of doors, a pin fire cartridge
may be used, and the barrel C will protect it from all wet. If desired, a spike
may be affixed underneath the aforesaid base, or pedestal B, for fixing my alarm
signal in the ground.
Having now particularly described and ascertained the nature of this my
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
The Construction of Alarm Signals substantially as hereinbefore described, and
for the purposes herein set forth.
