IMPROVEMENTS IN SMALL ARMS AND ORDNANCE AND IN PROJECTILES THEREFOR to
Year: 1885

page_text: <
I, GEORGE ROWELL, of 18 Falcon Road London S.W. Doctor of Medicine do
hereby declare the nature of my invention for IMPROVEMENTS IN SMALL ARMS AND
ORDNANCE AND IN PROJECTILES THEREFOR to be as follows:-
The rifling is a "Spiral Sigmoid" which in guns intended to shoot a charge of
multiple shots is limited to the muzzle end and may be detachable. The chamber
is made eccentric to the bore, meeting this at an obtuse angle. The breech-action
consists of a revolving block, channelled on its periphery, serving as a carrier of the
cartridges to a point in a line with the chamber into which they are inserted by a
plunger." The carrier is fed by a magazine which, when in use, stands vertically,
and in this position may further be surmounted by a cartridge-box or pouch; and,
when not in use, lies alongside the stock, or beneath the breech end of the barrel;
while a supplemental magazine consists of a cartridge bandolier, modified from that,
in common use by marksmen. The "backsight" is L-shaped, turning on its angle;
the elevating arm of the sight terminates in a broad plate, perforated by a semi-
circular or triangular opening, communicating by a notch midway with the upper
border of the plate; the short arm is broad, and open internally. The "foresight
is curved superiorly, and may be solid or perforated. The projectiles are made with
the body cylindrical; the rear of a "Spiral Sigmoid" form; and the head may be
of the same Sigmoid form, or have curved chisel-shaped projections the better to
obviate glancing off on impact. When made of a compressible metal, they are
cannelured at the shoulder.

Improvements in Small Arms and Ordnance and in Projectiles
therefor.
I, GEORGE ROWELL 42 Richmond Road South Kensington London, S.W. Doctor
of Medicine, do hereby declare the nature of my invention for IMPROVEMENTS IN
SMALL ARMS AND ORDNANCE AND IN PROJECTILES THEREFOR, and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
The accompanying Drawings and following description will clearly show the
nature of my Invention.
The rifling is a "spiral, sigmoid," (Figs. 1, 2, 3,); at the breech end it is of the
form shown in Fig. 1, while towards the muzzle it is shaped as in Fig. 2; it may,
however, be of either form throughout. In guns intended to shoot a charge of
multiple shots the rifling is limited to the muzzle end, towards which it narrows;
the rifled muzzle end may be detachable, (Fig. 3).
The chamber is made eccentric to the bore meeting this at an obtuse angle.
The breech-action consists of a revolving block (Fig. 11, a) channelled on its
periphery, serving as a carrier of the cartridges to a point in a line with the chamber,
into which they are inserted by a "plunger" or bolt (Fig. 11, 6). The carrier is fed
by a magazine, which, when in use, stands vertically (Fig. 11, c, c, Fig. 12, c), and
in this position may further be surmounted by a cartridge-box or pouch (Fig. 12, d);
and when not in use lies alongside the stock (Fig. 11, c) or beneath the breech end
of the barrel; while a supplemental magazine consists of a cartridge bandolier,
modified from that in common use by marksmen. The vertical magazine is attached
to either side of the breech-case by a round-headed button or stud on its inner face
being received into a round-ended slot in the opposed face of the breech-case, and
in which the stud is free to revolve when the magazine is turned down. The stud
may be retained in the slot by a spring catch. Or the relative positions of the stud
and slot may be reversed,-that is to say, the slot may be in the side of the magazine,
and the button on the breech-case. Or the magazine may rest upon a small platform
or-be received into a small cage swinging upon a headed pin projecting from the
side of the breech-case.
The "backsight" (Figs. 5, 6, 7,) is L-shaped, turning on its angle. It consists of
two arms; the longer and elevating arm terminates in a broad plate, rigid or capable
of lateral motion on a graduated slide (Fig. 5, a) and perforated by a semicircular,
segmental, or triangular opening (Figs. 6, 7, b, b) communicating by a notch (Figs. 6,
7, c, c) with the upper border of the plate, within which a spirit-level may be placed
(Fig. 7); the shorter arm (Fig. 5, d) by which the range is judged and the elevating
arm is adjusted is broad and open internally. The "foresight" (Fig. 4), which may
be solid or perforated (Fig. 4, a), is curved superiorly, and guarded by two pillars,

page_text: rounded superiorly, and united by a band which when raised arches over the cone
(Fig. 4, c, interrupted line).
:
The projectiles (Figs. 8, 9, 10,) are made with the body cylindrical (a); the
rear (b) of a taper "spiral sigmoid" form; and the head may be of the same sigmoid
form, or have curved chisel-shaped projections (Fig. 8, c) the better to obviate
glancing off on impact. The heads may be made of the same material as the rest
of the projectile, or may be of lighter material (Fig. 10, f); When made of a soft
compressible metal they are recessed, or cannelured at the shoulder (Fig. 9, d, e).

page_text: 3. A self-adjusting "backsight" with a perforated sight-plate and spirit-level,
substantially as described and shown in Figs. 5, 6, 7.
4. A "foresight," solid or perforated, with lateral and arched guards, substantially
as described and depicted.
5. Projectiles with "spiral sigmoid" rear; with head of similar form, or with
chisel-shaped projections, or recessed or cannelured at the shoulder, or of lighter
material, substantially as described and delineated.
