Improvements in Martini and other Breech Loading Fire Arm
Mechanism.
We, CARL BENJAMIN ENGELS and WILLIAM FIELD, trading as The Field Rifle
Company, of 58, Cambridge Street, in the City of Birmingham, Manufacturers,
do hereby declare the nature of this invention to be as follows: ―
This invention relates to improvements in Martini and other breech loading
fire arm mechanism or such arms that are constructed upon the same lines,
part of which improvements may be applied to other breech loading fire arms,
and its object is to provide improved means whereby the internal mechanism
in the action body may be readily withdrawn for inspection cleaning &c., or
what is generally known as stripping or dismounting without interference of
strength or arrangement of moving parts, and in such a manner that when thus
removed, the lever, tumbler, trigger, trigger guard and its body, and the extractor
shall be connected together as a whole, and thus avoid the danger of losing loose
parts, as would be the case if, as is usual, these parts were further separated;
also that the breech block with its striker &c. shall be removable in a similar
manner as another part, independently of the first part; also to provide an indi-
cator mechanism to show whether there is a cartridge in the barrel or not.
According to this invention the fulcrum joint of the lever and of the tumbler.
is carried upon a tubular pin or sleeve which is tightly fitted in the two sides
of this trigger guard body, but which can be driven out if desired; thus when
the trigger guard body is separate from the action body, the lever, tumbler, and
the extractor, cannot fall therefrom and thus get lost. A central fulcrum pin
is used to pass through the one side of the body and through the tubular pin or
sleeve to the other side of the body, one of which is screwthreaded.
fore part of the trigger guard body the extractor is similarly carried upon a
tubular sleeve, which is then also similarly secured by a central screw pin as
at the other end.
At the
The block is also secured by a similar fulcrum screw pin passing through
the sides of the body and through the block.
These pins are furnished with enlarged milled edged heads by which they
may be readily inserted or removed by hand.
Thus by these means when the said screws are removed the lever, tumbler
trigger guard and its body, and the extractor, are easily removed bodily as one
part, and the block with its accessory parts as another part.
The indicating mechanism is somewhat as follows:-
Through the breech body and the screw end of the barrel, or through such
other necessary part or parts at the loading end of the barrel or barrels, a hole
is drilled from the outside, and usually in an oblique direction, which emerges
upon the inside at a point immediately behind the recess into which the head
of the cartridge fits (or such other place where the desired effect may be attained.)
In this hole is fitted a sliding pin which is pressed inwards by spring action

page_text: so that its inner end protrudes through the barrel end when there is no cart-
ridge case in, while under such circumstances its other end is sunken and
hidden from view; but upon the insertion of a cartridge, the pin is pushed
forward so that its end protrudes through the upper exterior of the action body
or other suitable part, and thus indicates the presence of the cartridge. Upon
the removal of the cartridge case the spring action immediately causes the pin to
enter inwards and disappear from view. It will be readily seen that this latter
part of our invention would apply to any or most breech loading fire arms.

Improvements in Martini and other Breech Loading Fire Arm
Mechanism.
We, CARL BENJAMIN ENGELS and WILLIAM FIELD, trading as The Field Rifle
Company, of 58, Cambridge Street, in the City of Birmingham, Manufacturers,
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:―
This invention relates to improvements in Martini and other breech loading
fire arm mechanism or such arms that are constructed upon the same lines,
part of which improvements may be applied to other breech loading fire arms,
and its object is to provide improved means whereby the internal mechanism
in the action body may be readily withdrawn for inspection cleaning &c., or
what is generally known as stripping or dismounting, without interference of
strength or arrangement of moving parts, and in such a manner that when thus
removed, the lever, tumbler, trigger guard and its body, and the extractor
shall be connected together as a whole, and thus avoid the danger of losing loose
parts when cleaning the gun; also that the breech block with its striker &c.
shall be removable in a similar manner as another part, independently of the
first part; also to provide an indicator mechanism whether there is a cartridge
in the barrel or not.
In order to more clearly explain this our invention we have appended hereunto
an illustrative drawing upon which are figures and numbers of reference, similar
numbers referring throughout to the same thing or part.
Fig. 1, is a general side view of the action body &c. with the breech closed.
Fig. 2, is a part sectional plan view on line A-B Fig. 1, showing the method
of securing the several parts in the action body.
Fig. 3, is a side view of the trigger guard body, trigger guard, lever, tumbler
&c., as seen when removed from the action body. Fig. 4, is a part sectional
view on line C-D Fig. 3. Figs. 5, 6 & 7, show detached views of the pins for
securing the parts in the action body. Fig. 8 is a part sectional view showing
the indicator device. Figs. 9 & 10, are detached views of the tubular sleeves
through which are passed the pins shown in Figs. 6 and 7.

According to this invention the fulcrum joints of the lever 11, and of the
extractor 16, are carried upon tubular pins or sleeves 19, 19, see Figs. 2 & 4,
which are tightly fitted in the two sides 20, 20, of the trigger guard body 15

page_text: but which can be driven out if desired; or they may be screwthreaded into the
side 20; thus when the trigger guard body 15, is separated from the action body,
as shown in Figs. 3 & 4, the lever 11, tumbler 12, and the extractor 16, cannot
fall therefrom and thus get lost. Central fulcrum pins 21, 21, are passed
through the one side of the body 10, and through the tubular sleeves 19, 19ª,
to the other side of the body 10, one of which sides is screw-threaded, thus secur-
ing the whole in position in the action body. The breech block 22, shown in
dotted lines in Fig. 1, is also secured by a similar fulcrum screw pin 23, passing
through the sides of the body and through the block, in the ordinary manner.
These pins 21, 21 and 23, are furnished with enlarged milled edged heads of
any suitable shape, by which they may be readily inserted or removed. Thus
by these means when the said screw pins 21, 21, and 23, are removed, the lever,
tumbler, trigger guard and its body, and the extractor, are easily removed bodily
as one part as seen in Figs. 3 and 4, and also the breech block 22, with its
accessory parts as another part.
The indicating mechanism is somewhat as follows:-
Through the action or breech body 10, and the screw end 24, of the barrel 17,
or through such other necessary part or parts at the loading end of the barrel
or barrels, see Fig. 8, a hole is drilled from the outside, and usually in an
oblique direction, which emerges upon the inside at a point immediately behind
the recess 25, into which the head 26, of the cartridge fits (or such other place
where the desired effect may be attained). In this hole is fitted a sliding pin 27,
which is pressed inwards by spring 28, so that its inner end 29, protrudes through
the barrel, when there is no cartridge case in, while under such circumstances
its other end 30, lies sunken and hidden from view; but upon the insertion of
a cartridge, the più 27, is pushed forward so that its end 30, protrudes through
the upper exterior of the action body or other suitable part, as shown in Fig. 8,
and thus indicates the presence of the cartridge 18. This pin 27, and spring 28,
is held by screw nut 31. Upon the removal of the cartridge case the spring
action immediately causes the pin to enter inwards and disappear from view.
It will be readily seen that this latter part of our invention would apply to any
or most breech loading fire arms.
Having now particularly described and ascertained the nature of this our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:
__
1. The combination and employment with the breech mechanism of Martini or
similar fire arms, of the tubular fulcrum sleeves 19 and 19ª, with pins substan-
tially as set forth and shown and for the purposes specified.
2. In Martini or similar fire arms, the combination with the body 10, trigger
guard body 15, and its accessory parts, of the tubular fulcrum sleeves 19, 19",
substantially as set forth and shown and for the purposes specified.
3. The combination with small arms breech loading mechanism, of the indi-
cator pin 30, adapted and arranged to be operated by the head, of the cartridge
case, substantially as set forth and shown.
