PROVISIONAL SPECIFICATION.
Improvements in Ordnance.
JAMES HILLERT PERRY 28 Tolmers Square, Hampstead Road, London N.W.,
Private and Independent Gentleman, pursuing the Physical Chemical and Exact
Sciences, in relation to Offensive and Defensive Naval and Military Engineering in
Warfare do hereby declare the nature of this invention to be as follows:-
My invention constitutes improvements in brecchloading naval, field and fort guns
and consists of mechanism for opening, loading, closing and locking the breech
between the barrel and culasse of the cannon and the purpose of discharging projectiles
of the description stated in my specification.
This invention is constructed in two pieces of wrought iron, steel, or brass, the one
piece from the muzzle to the breech is the barrel and the second piece from the breech
to the stem, is the culeron or culasse. The barrel and culasse are rifled grooved, in
any desirable number according to the calibre in the bore of the cannon. Towards or
at the breech I place a solid breech block hinged at one side of the gun, and closing
towards the opposite side with mechanism for locking or unlocking the aforesaid
breech.
The process of loading is effected by placing the projectile, with the cartridge in
the breech bore; the breech block is then closed and secured by the locking mechanism
at the side opposite to the hinge.
The gun is fired by the ordinary friction tube.
The object of my invention is to facilitate a quicker way of opening the breech,
loading the gun, closing and locking the breech, and discharging the gun than is
effected by any other breech loading gun hitherto adopted in the artillery
service.
The cartridge projectile, I introduce is more compact in form and destructive in its
explosive power.

Improvements in Ordnance.
1, JAMES HILLERT PERRY, of 28 Tolmers Square, Hampstead Road, N.W. in the
County of London, Private and Independent Gentleman, pursuing the Physical
Chemical and Exact Sciences, in relation to Offensive and Defensive Naval and
Military Engineering in Warfare, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
-
My invention constitutes improvements in breechloading naval, field and fort guns,
and consists of mechanism for opening, loading, closing and locking the breech
between the barrel and culasse of the cannon and the purpose of discharging projectiles
of the description stated in my specification, or those now in common use.
And in order that my invention may be thoroughly understood, I now proceed to
describe the accompanying drawings thereof, reference being had to letters and
figures marked thereon.
Figure 1 represents the plan at the top of the gun d, with the breech block a,
hinged at c to the gun, pivoted by the bolt b, with a bolt attached to the chamber;
for the purpose of securing the closing of the breech by means of a screw at f forcing
the inside head of the bolt in the recess g (figure 2).
Figure 2 denotes an elevation of the breech open to receive the projectile and

cartridge. The breech block may be placed at any angle for the purpose of not
obstructing the operation of loading. When the breech block a is closed the bolt h
(being loosely pivoted in the chamber j), passes into the recess g, and the screw at f
is screwed up tight to force the bolt head into the portion described by dotted
lines.
Figure 3 is the end elevation of the breech when the breech block a is locked for
the purpose of being discharged or otherwise.
Figure 4 is a side elevation of the locking mechanism on the gun d and the breech
block a, the parts of this figure being broken off for want of space.
This invention is constructed in two pieces of wrought iron, steel, gun-metal, or
brass, the one pieco from the muzzle to the breech is the barrel d, and the second
piece from the breech to the stem, is the culeron or culasse. The barrel d and culasse
are rifled grooved, in any desirable number according to the calibre in the bore i of
the cannon, spiral or otherwise. Towards or at the breech I place a solid breech
block a, hinged at c on one side of the gun, and closing towards the opposite side
with mechanism for locking or unlocking the aforesaid breech.
The process of loading is effected by placing the projectile, with the cartridge in
the breech bore ; the breech block a is then closed and secured by the locking
mechanism and f, at the side opposite to the hinge c.
The gun is fired by the ordinary friction tube in the vent hole e.
The object of my invention is to facilitate a quicker way of opening the breech,
loading the gun, closing and locking the breech, and discharging the gun than is
effected by any other breech loading gun hitherto adopted in the artillery
service.
The cartridge projectile, 1 introduce is more compact in form and more destructive
in its explosive power than, those hitherto in use.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
First: The combination of the gun and breech d, with the hinged "solid breech
block a, and the locking mechanism, to lock the bolt when the breech is closed,
substantially as herein described and according to the accompanying drawings.
Secondly: The combination of the breech block hinged to the gun by the bolt, and
the locking bolt head to press in the recess g by the screw, to lock the breech,
substantially as herein described and according to the accompanying drawings.
:
Thirdly The combination of the various parts to form the piece of ordnance, as
illustrated in figures 1, 2, 3, and 4, to be constructed of any metallic substance, any
size, and the barrel to have any number of spiral or other grooves substantially as
'berei described.
Dated this 18th day of April 1890.

Applicant.
