Improvements in and relating to the Breech Mechanism of Martini
Guns and Rifles.
We, WILLIAM GRAH, of 6, Place de Bronckart, Liége, in the Kingdom of Belgium,
Manufacturer of Fire Arms, and PAUL DELHOUNE, of Cheratte, Belgium, Gunsmith,
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 has for object an improved arrangement of the mechanisin of
Martini rifles which will allow of the putting together and taking apart of such
mechanism without necessitating the use of tools.
On the accompanying sheet of drawings:
Figure 1 is an outer side view of the breech mechanism of a Martini rifle.
Figure 2 shews the internal mechanism arranged on a plate, and ready to be intro-
duced into the breech.
Figure 3 shews the plate of the trigger guard, provided on its upper side with a
projection C intended to secure the mechanism in place during the putting together
of the parts and when the mechanism is withdrawn from the weapon.
Figure 4 is a plan view of the plate of the trigger guard.
Figures 5 and 6 are, respectively, a side view and a sectional plan on
line 1,-2,-3,-4, of the plate on which is arranged the mechanism of the fire arm.
Figures 7 and 8 are two views of the assembling screws of the mechanism, for
connecting the plate (Figures 5 and 6) to the breech plate R.
The putting together and taking apart of the mechanism of a Martini gun or rifle
usually presents serious difficulties and this invention is designed to obviate such
difficulties by arranging the mechanism of these fire arms upon a special plate A
which is afterwards introduced and fixed in the breech. On this plate A are formed
or fixed two tubes, A¹ A² and a pivot A³ which serve as axes for the parts of the
mechanism and, at the same time, the two former act as bearings or bushings for
screws B which fix and secure the said plate A in the breech.
The extractor D) is mounted or pivoted on the tube A¹; the operating lever E and
the gear I are mounted on the tube A2 and the breech block F on the pivot A³. The
trigger G
as usual, mounted on the plate H of the guard, and this is placed and
secured on the tubes A¹ and A². The mechanism must be cocked by means of the
lever E in the usual manner, so that it may be introduced into the breech
chamber; the plate of the trigger guard H is furnished with a tongue or
projection C, Figures 2 and 3, which serves to hold the cocked mechanism in place
before its introduction into the breech chamber.
The whole of the mechanism thus mounted on the plate A is cocked and then
introduced with this plate A from underneath, into the breech; afterwards, it is fixed
by means of the two screws B which pass through the wall or casing of the breech
and being threaded are screwed into the side plate R, their plain stems or sbanks
passing along the tubes A¹ and A².

page_text: These screws are inserted and removed by hand, and when removed, it is easy to
withdraw the mechanism of the breech and, without the assistance of any tool, each
part of the mechanism may be removed from its pivot A', A², and A³.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what we
claim is :-
1. The arrangement of the parts or the mechanism of Martini guns and rifles upon
a special plate A furnished with axes of rotation for these parts which plate is intro-
duced and fixed in the breech on the weapon, as described.
2. In the mechanism of Martini guns and rifles the combination of a trigger guard
plate having a projection C, with a plate A having tubes A1 and A2 and a pivot A³ on
which the parts of the mechanism are pivoted, and of connecting screws B securing
said parts in position after insertion in the cocked position of the breech mechanism,
substantially as and for the purposes described with reference to annexed drawings.
