We, ARTHUR TREVOR DAWSON, Superintendent of Ordnance Works, and GEORGE
THOMAS BUCKHAM, Engineer, both of Vickers, Sons & Maxim, Limited, of 28,
Victoria Street, Westminster, in the County of London, do hereby declare the
nature of this invention to be as follows:-
-
Our invention relates to "separable" guns, such as mountain, boat and light field
guns, made in sections easily separated for transport.
According to this invention we construct our gun of the following separable
parts: the barrel, the jacket in halves, the breech piece, and the locking ring.
The barrel in which is formed the entire bore and the chamber, extends nearly the
whole length of the gun, and may consist of an inner tube reinforced by outer tubes
or wire. When wire is employed, we encase it by a sheath to protect it when the
jacket is removed. Keys are provided to prevent the barrel from turning relatively
to the jacket owing to the rotation of the projectile.
The jacket on which are formed the trunnions, locking lugs and sight brackets,
is divided longitudinally in halves the joint being preferably in a vertical plane.
Interrupted or continuous threads are formed on the front and rear ends of the
jacket and its two halves are secured on the barrel by means of the locking ring on
the front and the breech piece on the rear end of the jacket.
The breech piece and locking ring are so fitted that when screwed home against
a stop they always occupy the same positions.
The front part of the jacket is reduced in its inside diameter so as to form a
shoulder or recess fitting a corresponding shoulder or collar on the barrel.
The breech piece projects somewhat to the rear of the jacket and barrel, the
projecting part being internally screwed to receive the breech screw. Lugs are
formed on the breech piece for hinging the breech mechanism and also lugs for
attaching the elevating gear.
The locking ring which secures the front end of the jacket on the barrel is held by
the catch of the front sight or other suitable catch and the breech piece is locked to
the jacket by a catch acted upon by the breech mechanism.
The halves of the jacket instead of being held by the breech piece and locking
ring may be secured together by bolts or by a hinge on the one side and bolts on the
other side.
To separate the gun, the breech mechanism is removed and the breech piece and
locking ring are unscrewed, or the halves of the jacket are unbolted so that they are
easily separated from the barrel.

We, ARTHUR TREVOR DAWSON, Superintendent of Ordnance Works, and GEORGE
THOMAS BUCKHAM, Engineer, both of Vickers, Sons & Maxim, Limited, of 28, Victoria
Street, Westminster, in the County of London, 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 :-
Our invention relates to "separable" guns, such as mountain, boat and light field
guns, made in sections easily separated for transport as we shall describe referring to
the accompanying drawings.
Fig. 1 is a longitudinal section, Fig. 2 is an end view and Fig. 3 is a plan of a
separable gun according to our invention. Fig. 4 is a transverse section of the
breech piece on the line 4-4 of Fig. 3 and Fig. 5 is an end view of the locking ring.
As shewn in the drawings we construct our gun of the following separable parts:-
the barrel a, the jacket b in halves, the breech piece c, and the locking ring d.
The barrel a in which is formed the entire bore and the chamber, extends nearly
the whole length of the gun, and may consist as shewn of an inner tube e reinforced
by outer tubes f or wire g. When wire is employed, we encase it by a sheath / to
protect it when the jacket 6 is removed. Keys are provided to prevent the barrel
from turning relatively to the jacket owing to the rotation of the projectile.
The jacket b on which are formed the trunnions k, locking lugs and sight
brackets m, is divided longitudinally in halves the joint being preferably in a
vertical plane.
Interrupted or continuous threads are formed in the front and rear ends of the
jacket and its two halves are secured on the barrel by means of the locking ring d
on the front and the breech piece c on the rear end of the jacket.
The breech piece c and locking ring d are so fitted that when screwed home against
a stop they always occupy the same positions.
The front part of the jacket is reduced in its inside diameter so as to form a
shoulder or recess fitting a corresponding shoulder or collar on the barrel as shewn
at n.
The breech piece c projects somewhat to the rear of the jacket and barrel, the
projecting part being internally screwed to receive the breech screw. Lugs p are
formed on the breech piece for hinging the breech mechanism and also lugs q for
attaching the elevating gear.
The locking ring d which secures the front end of the jacket on the barrel is
prevented from turning by a spring bolt held in position by the catch of the front
sight which is inserted at m or other suitable catch and the breech piece c is locked
to the jacket by an oblique setting screws held in position by the hinge bolt of the
breech mechanism inserted in the lugs p.
The halves of the jacket instead of being held by the breech piece c and locking
ring d may be secured together by bolts or by a hinge on the one side and bolts on
the other side.
To separate the gun, the breech mechanism is removed and the breech piece c and
locking ring d are unscrewed, or the halves of the jacket are unbolted so that they are
easily separated from the barrel.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is-

page_text: A separable gun consisting of a barrel piece reinforced or wired, a jacket made in
halves, a breech piece screwed on the rear end of the jacket, and a locking ring
screwed on its front end substantially as described with reference to the drawings.
