IMPROVEMENTS IN ALARM GUNS FOR THE PROTECTION OF GAME AND OTHER PROPERTY
Year: 1885

page_text: ARCHIBALD FARQUHARSON Gamekeeper Weald Park Brentwood Essex do hereby
declare the nature of my invention for IMPROVEMENTS IN ALARM GUNS FOR
THE PROTECTION OF GAME AND OTHER PROPERTY to be as follows:-
For this purpose I employ a cast iron frame and barrel conjointly: (or of any
other suitable material) the barrel being bored out to suit a No 8 pin fire cartridge
and at the back end of same are two slot holes at right angles to one another: one
for the purpose of allowing the pin of the cartridge to pass into the barrel, and the
other for the purpose of dropping a small wro't iron plate at the back of the
cartridge when in position, to form a concussion or breech block plate: the said
plate being either loose or attached by means of a hole being drilled in the top
corner of same to fit a pin or bolt which is fitted and fixed to two lugs or ears
cast to barrel same being drilled to suit the pin or bolt. I also use a steel pointed
lever with 3 or more points at the one end, so that same can be set at any angle,
and whose fulcrum is close to the points, and the length of same can be made as
may be required, and to the other end are attached the trailing wires.
A flat steel spring is fixed to one part of the cast iron frame which when set is
resting upon one of the points of the lever, and as soon as the trailing wires are
touched they move the lever which at the same time releases the spring on to the
pin of the cartridge which is immediately discharged: underneath the spring is
attached to the cast iron frame a safety block, by means of two lugs or ears cast
to the frame: and same being drilled & fitted with a pin or bolt so that the said
block can be raised up for the spring to rest upon while the gun is being set, so as
to prevent the spring slipping and firing the cartridge: and also near where the
end of the spring is attached to the frame by means of a set screw, two lugs or
lips are cast on frame, between which the spring is placed, and one side of the left
lip is slightly recessed to allow the spring to move on one side while the gun is
being loaded, and also that when the spring is set on either of the points of the
lever the two lags or lips prevents the spring moving sideways. The cast iron
frame and barrel are made light and portable and can be easily fixed to 'any stump
or tree & with coach screws or otherwise.

ARCHIBALD FARQUHARSON Gamekeeper Weald Park Brentwood Essex. I do
hereby declare the nature of my invention for IMPROVEMENTS IN ALARM GUNS
FOR THE PROTECTION OF GAME AND OTHER PROPERTY and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement :—
For this purpose I employ a cast iron frame and barrel conjointly (or of any
other suitable material): the barrel being bored out to suit a N° 8 pin fire cartridge;
and at the back end of same are two slot holes at right angles to one another; one
for the purpose of allowing the pin of the cartridge to pass into the barrel, and the
other for the purpose of dropping a small wrot iron plate at the back of the
cartridge when same is in position so as to form a concussion or breech block plate,
the said plate being either loose or attached by means of a hole being drilled in
the top corner of same to fit a pin, which is fitted to two lugs or ears cast to the
barrel, same being drilled to suit the pin or bolt. I also use a steel pointed lever
with 3 or more points at one end, so that same can be set at any angle, and whose
fulcrum is close to the points, and the length of same can be made as may be
required, and to the end of which are attached the trailing wires. A flat steel
spring is fixed to one part of the cast iron frame by means of a set screw, which
when set is resting upon one of the points of the lever, and as soon as the trailing
wires are touched they move the lever, which at the same time releases the spring
on to the pin of the cartridge which is immediately discharged: underneath the
spring there is attached to the cast iron frame a safety block by means of two lugs
or ears cast to the frame, same being drilled and fitted with a pin or bolt, so that
the said block can be raised up for the spring to rest upon while the cartridge is
being fixed and the gun being set, so as to prevent the spring slipping and firing
the cartridge, and also near where the end of the spring is attached to the frame,
two lugs or lips are cast on same, between which the spring is placed, and one side
of the left lip or lug is slightly recessed to allow the spring to move on one side
while the gun is being loaded, and also to allow the breech block or plate to fall
right back when required, and also that when the spring is set on either of the
points of the lever the 2 lugs or lips will prevent the spring from moving sideways.
The cast iron frame and barrel are made light and portable, and can be easily fixed
to any stump or tree &c with coach screws or otherwise,
In order that my invention may be more fully and clearly understood, I will
herewith aided by the accompanying drawings describe the same.
