COMPLETE SPECIFICATION
Improvements in Quick Firing Guns.
1, ERNESTO BREDA, of No. 7, Via Antonio Bordoni, Milan, Italy, Mechanical
Engineer, 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 :-
My invention relates to quick firing guns and comprises improvements in the
breech block and breech mechanism of such guns.
The breech block is made in the form of a stirrup which is mounted so as to
swing on two pivot pins provided on the breech at right angles with the axis of
the gun.
Supposing the said pivot pins to be in a vertical position, then by shifting the
bottom of the stirrup sidewise the breech will open itself and the extractor will be
operated and caused to draw out the metallic cartridge case enclosing the charge.
On the introduction of a new cartridge the said cartridge is forced home by the
closing of the breech block, and the gun is then ready for firing.
Within the breech block there is a central percussion lock which is automatically
cocked during the opening of the breech and which then remains ready for firing
when the breech is closed.
In the annexed drawings I have shown my improved breech block and
mechanism applied to a gun of small calibre.
Figure 1 is a longitudinal central section, taken at right angles to the pivot of
the breech block of a gun constructed according to my invention the breech being
closed.
Figure 2-ib a similar section, the breech being open and ready for receiving a
cartridge.
Figure 3 is a plan of Figure 1.
a is the operating handle by moving which in the direction of the arrow
Figure 1 the percussion-lock is opened and the breech block is unlocked. On the
breech being opened a lug striking the extractor c throws out the cartridge
casing.
When a new charge has been introduced, by moving the handle in the opposite
direction to that of the arrow, the surface d Figure 2 completes the introduction
of the cartridge case, the plug closes itself, and by operating the percussion-look
the gun is fired.
The base of the metallic. cartridge is made of a spherical shape and the face d
of the breech block is formed in a like manner.
The external form of the charge with the cartridge case having a spherical
shaped base is shown in Figure 1.

page_text: Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
First. The breech block and breech mechanism for a quick-firing gun, con-
structed substantially as herein described with reference to the accompanying
drawings.
Second. A quick-firing gun provided with a breech block and breech mechanism,
substantially as hereinabove described and operating as specified.
Dated this 10th day of July 1891.
