PROVISIONAL SPECIFICATION.
Improvements in Sporting Guns.
FREDERICK HERBERT MABERLY Stonycroft, Soho Hill, Handsworth, Bir-
mingham Physician and Surgeon, do hereby declare the nature of this invention to
be as follows:
It consists in an arrangement instantly attachable to or removable from either
single or double barrelled guns whether smooth or choke bore, the object being to
(a) lengthen barrel or barrels (b) convert smooth bores into choke (c) continue
existing choke or smoothbore, thus giving greater range & improved shooting.
This I do by making a shouldered or bored out tube or tubes to fit accurately over
barrel or barrels of existing guns: to be fixed to the same by spring, screw bayonet
catch or other method. These tubes for double barrelled guns are joined by ribs in
the usual way, the tubes & upper rib being slotted for a portion of their length
(1) to allow of passage of foresight and top and bottom rib (2) to grip the barrels:
A spring catch or other method of fixing being placed on under rib to engage in a
corresponding depression or elevation on under rib of the gun; for single guns a
bayonet catch to engage the foresight or other method may be used. An alternative
mode of fixing the appliance is to unscrew the foresight and to screw the same in
again through a hole provided in the tube or rib, thus avoiding slot shown in Figs. 4
& 5 (for double) or slot for bayonet catch as in Fig. 7 (for single guns). The
outward contour of the tubes may either be simple cylinders as in Fig. 7 or
diminished as in Figs. 1 & 2 but the interior shoulder is invariably truly bored to
coincide with bore of gun as shown in Figs. 1 & 2. The tubes may be either
cylinder or chokebore and may be made of any desired length, calibre or suitable
metal. To counterbalance weight of tubes and thus preserve the true balance of
gun I apply a sufficient weight in the stock, either in the side or under the heel
plate which may be affixed or removed at will, a place being provided for it.

Improvements in Sporting Guns.
FREDERICK HERBERT MABERLY, Stonycroft, Soho Hill Handsworth Bir-
mingham Physician and Surgeon 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 :-
It consists in a separate muzzle piece speedily attachable to or removable from
either single or double barrelled guns, whether cylinder or choke bore, the object
being (a) to lengthen the barrel or barrels (6) convert cylinders into choke
(c) continue existing choke or cylinder bore-thus giving greater range and improved
shooting. This I do by making a shouldered or bored out tube or tubes to fit
accurately over barrel or barrels of existing guns-to be fixed to the same by
spring, screw, bayonet catch or other method. These tubes for double barrelled
guns are joined by ribs in the usual way the tubes and upper rib being slotted for a
portion of their length, or I may flute the upper rib instead of slotting it, (1) to
allow of passage of foresight (2) to grip the barrels, a spring catch, screw or other
method of fixing being placed on under rib to engage in a corresponding depression
or elevation on under rib of the gun-for single guns a bayonet catch to engage the
foresight or other method may be used. An alternative method of fixing the
appliance is to unscrew the foresight and to screw the same in again through a hole
provided in the tube or rib, thus avoiding slot shown in Figs. 4 & 5 (for double) or
slot for bayonet catch as in Fig. 7 (for single guns). The outward contour of the
tubes may either be simple cylinders as in Fig. 7 or diminished as in Figs. 1 & 2.
The tubes may be either cylinder or choke bore and may be made of
any desired
length and calibre and of any suitable metal. To counterbalance weight of tubes
and thus preserve the true balance of the gun I apply a sufficient weight in the
stock either in the side or under the heel plate, which may be affixed or removed
at will, a place being provided for it.
Referring to the drawings filed with my Provisional Specification

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―
A separate or loose muzzle piece for attachment to sporting guns, part of which
fits accurately over and grips the muzzles of the same, made in the manner and for
the purpose herein, described and as set forth in the drawings attached thereto.
Dated this 21st day of August 1893.
