fig. A a half turn, which action secures Cap, fig. A, to the barrel and consequently
encloses the Cartridge.
Wires or strings are then attached to the eyelet in J catch, fig. E, and carried in
the required directions and made secure to posts, gates doors or trees, as required,
this being done, the safety Block Peg or Pin fig. D on drawing is to be withdrawn
and left hanging by the chain, which action leaves the gun suspended on the
J catch, fig. E, on drawing, now, any poacher, burglar or person passing over one
of the wires or strings immediately withdraws the J catch fig. E, and the gun
then falls down the iron rod on to the aforesaid iron plate on the ground, and
coming in contact with the iron plate drives the piston in, so as to strike the Cap
in the Cartridge, thus exploding it and giving the alarm. But so long as the
Safety Block Pin, fig. D, is inserted in the space F, the gun cannot be released from
its position, as shown in the drawing, and is therefore secure. This safety Block
Pin fig. D is a long felt want with alarm guns, as it securely prevents accidents
occurring, while setting the gun which happens so often with all alarm guns at
present in use.

page_text: Improvements in the Construction and Setting of Alarm Guns.
HENRY PERRINS and HERBERT EDWARD POLLARD Gun rifle and revolver
Manufacturers of 59 Broad Street Worcester Trading under the name or style of
Perrins & Son do hereby declare the nature of our invention for IMPROVEMENTS IN
THE CONSTRUCTION AND SETTING OF ALARM GUNS and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :—
Alarm gun in two parts, the barrel or body part which receives the cartridge is
iron, the cap or breech part Fig. A on drawing is of brass and contains the striker
or piston, which is steel nickled, the cap is removed by means of a Key fig. B. on
drawing, which unlocks A as required this method of constructing the cap or breech
we claim to be quite original, and does away with the old or present system of
securing the cap on to the barrel, and which is so liable to get out of order or even
rendered useless by the repeated shock of explosion.
The gun consists of two parts, the body or barrel part which is made of iron, and
the other part is the cap or breech block which is made of brass. The barrel is
the part which holds the loaded cartridge, the cap is the part which contains the
striker or piston which explodes the cartridge, the piston is secured to the cap by
a screw pin, the cap is secured to the barrel by means of two flanges as shown in
drawing, and is removed by the use of Key fig. B.
MODE OF SETTING THE GUN.
The gun works up and down an iron rod, which rod is passed through an iron
plate into the ground which brings the whole gun etc upright, the gun is then to
be raised up the iron rod so far as will allow the J catch fig. E to be put under the
arm of gun, which action prevents the gun falling, then the safety block peд or
pin fig. D. is to be inserted in the space F. When this is done, the gun cannot
possibly fall and is secure, then the Key fig. B is to be fitted on to the cap, fig. A
and turned half round, having done that the cap fig. A can be removed, which
leaves the barrel open the cartridge can then be inserted in barrel, and the cap
fig. A is to be put back again on to the barrel by using the Key fig. B, and giving
the cap fig. A a half turn, which action secures cap fig. A to the barrel and con-
sequently encloses the cartridge.
Wires or strings are then attached to the eyelet in the J catch fig. E. and carried
in the required directions and made secure to posts, gates, doors or trees as required,
this being done, the safety block peg or pin fig. D ou drawing is to be withdrawn
and left hanging by the chain which action leaves the gun suspended on the
J catch fig. E on drawing, now any poacher, burglar or person passing over one of
the wires or strings, immediately withdraws the J catch fig. E, and the gun then
falls down the iron rod on to the aforesaid iron plate on the ground, and coming
in contact with the iron plate drives the piston or striker in so as to strike the
exploding cap in the cartridge thus exploding it, and giving an alarm.
But so
long as the Safety Block Pin fig. D remains inserted in the space F. the gun cannot
be released from its position as shown in the drawing, and is therefore secure.

page_text: This Safety Block Pin fig. D. is a long felt want with alarm guns, as it effectually
and securely prevents accidents while setting the gun, which happen so often with
all alarm guns now in use.
All Drawings referred to so far are those supplied with the Provisional
Specification.
FURTHER DESCRIPTION OF CAP OR BREECH BLOCK.
The Cap is the lower part of gun, and is removable.
The Cap has at the top end an extending rim, fig. H. as shown in Breech Block
drawing, Section 2. extending outward about of an inch, and also upward about
of an inch, thus leaving a circular sunken space, as shown in Breech Block
drawing Section 1 and 2-space I.
In the rim fig. H. there are two slots or openings as shown in Breech Block
drawing Section 1. figs. K. through which the two flanges or arms attached to the
barrel or body part pass-and when the two flanges are through these slots, a half
turn of the cap by means of the Key fig. B brings the the two flanges under the
rim of Breech Block. Thus the Breech Block is held firmly and securely to the
Body or barrel part, about 8 of an inch of the Body or barrel part sinking into
the space J. of Breech Cap, as shown in Breech Block drawing Section 1, and also
shown in Section 2 by the dotted lines, space I.
The cap or Breech block contains the striker which is shown in Section 2 Breech
Block drawing by the dotted lines running upward from fig. L to fig. L. the end of
striker which explodes the is shown in the centre of space 1-by the fig. L Section 1
of Breech Block drawing.
The striker is held in its place by means of a screw pin fig. G. shown in section 2
of Breech Block drawing-this screw pin running into a slot cut in striker about
of an inch-thus allowing the striker about of an inch play or movement.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is
1. The Safety Block pin fig. D on drawings.
2. The J catch fig. E on Drawings.
3. The Cap and mode of attaching same to the barrel of gun.
