An Improvement in Breech Loading Small Arms.
I, WILLIAM CASHMORE, of 130, Steelhouse Lane, in the City of Birmingham,
Gun and Pistol Manufacturer, do hereby declare the nature of this invention to be
as follows:-
This invention has reference to those breech loading small arms in which the
breech loading action is locked to the barrels by means such as described in Mills'
Specification No. 19300 of A.D. 1894 namely by two downwardly projecting side
locking pauls or bolts which are jointed to the sides of the action and are adapted
to engage with side lumps or flanges formed on the outer sides of the breech end
of the barrel or barrels. As these pauls or bolts when engaging with the said
side lumps only prevent the action from turning down and do not assist the joint
pin of the action in resisting the backward pressure of the explosion, it follows that
there is considerable strain and wear on the said joint pin which it is the object
of my invention to minimise, which I effect as I will now describe.
I provide a small lamp or projection on each side of the breech action between
the front joint piu (which joints the action to the barrels) and the side lumps or
Hanges which are described in Mills' said specification as being fixed to or formed
with the breech ends of the barrels. 1 make my said lumps or projections on the
action of a curved shaped struck from the centre of the joint pin, or they may be
made straight or of other shape and I form e front surfaces of the said lumps
or projections on the barrels so as to match and abut against the said lumps or
projections on the action when the gun is closed.
The lumps or projections on the action abutting against the said side lumps or
projections on the barrels as above described, very greatly assist the said front
joint pin in resisting the longitudinal pressure of the explosion and thus prevent
undue wear and strain on the said joint pin.

1, WILLIAM CASHMORE, of 130, Steelhouse Lane, in the City of Birmingham,
Gun and Pistol Manufacturer, do hereby declare the nature of this invention and
in what manner the same is to he performed, to be particularly described and
ascertained in and by the following statement :-
This invention has reference to those breech loading small arms in which the
breech loading action is locked to the barrels by means such as described in Mills'
Specification No. 19300 of A.D. 1894 namely by two downwardly projecting side
locking pauls or bolts which are jointed to the sides of the action and are adapted
to engage with the side lumps or flanges formed on the outer sides of the breech
end of the barrel or barrels. As these pauls or bolts when engaging with the said

page_text: side lumps only prevent the action from turning down and do not assist the joint
pin of the action in resisting the backward pressure of the explosion, it follows that
there is considerable strain and wear on the said joint pin which it is the object of
my invention to minimise, which I effect as I will describe by referring to the
accompanying drawing on which
Fig. 1 is a side elevation of the breech part of a gun of the kind herein referred
to with my said invention applied thereto; Fig. 2 shews the same parts with the
breech open and Fig. 3 is a plan of the same with the barrels removed.
The same letters of reference indicate the same parts in all the figures.

are the two downwardly projecting side locking pauls or bolts which are
jointed at a to the sides of the action B and are operated by the top lever C and
adapted to engage with the two side lumps or flanges D (only one of which can be
seen on my drawing) which are formed on the outer sides of the breech end of
the barrel or barrels E. F is the joint pin of the action about which the
barrels turn.
According to this invention I provide two small lumps or projections, marked
respectively G G2, formed on the sides of the breech action between the front
joint pin and the side lumps or flanges D which are described in Mills' said
specification as being fixed to or formed with the breech ends of the barrels E.
I make my said lumps or projections G G2 on the action of a curved shape struck
from the centre of the joint pin F, or they may be made straight or of other
suitable shape, and I form the front surfaces d of the said lumps or projections D on
the barrels so as to match and shut against the lumps or projections G¹ G² on the
action when the gun is closed as in Fig. 1.
The lumps or projections G1 G2 on the action B abutting against the side lumps
or projections D on the barrels E as above described, very greatly assist the front
joint pin Fin resisting the longitudinal pressure of the explosion and thus prevent
undue wear and strain on the joint pin F.
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 :-
In breech loading small arms of the kind herein referred to provided with two
downwardly projecting side locking pawls or bolts jointed to the sides of the action
which when the gun is closed engage with side Jumps or flanges formed on the
outer sides of the breech end of the barrel or barrels, making the action with two
side lumps or projections such as G1 G2 shaped to abut against the said lumps or
flanges on the barrels to assist the action in resisting the backward pressure of the
explosion, all substantially as herein before described and illustrated by the
accompanying drawing.
Dated this 10th day of June 1896.
