IMPROVEMENTS IN GUNLOCKS
Year: 1884

page_text: I, JACOB BREDA BULL of 16 Kort Adlers Gade Christiania in the Kingdom of
Norway Newspaper Editor do hereby declaro the nature of said invention for
"IMPROVEMENTS IN GUNLOCKS" and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement:-
-
In using the firearms of the ordinary construction the sportsman as a rule
cannot go into the fields with his gun cockerl, for fear of the danger connected
therewith arising from its going off accidentally.
The present invention has for its object to make this possible without running
any risk; by this is attained the great advantage, that the gun is always ready for
shooting and that the game has less chance of getting away.
For this purpose a pawl or trigger hook is arranged in the lock, which bears
against the trigger in such a manner that it is impossible to discharge the gun in
the usual manner. An arrangement of that description is broadly not new; the
constructions however up to the present time have had these di-advantages that the
releasing of the before named pawl or trigger hook which must take place before
firing is just as tiring and just as tedious as cocking the gun and thus the advantage
gained is quite illusory; In order to obviate the disadvantage the rolea-ing appliance
for the trigger hook in this present invention is brought out on the top of the gun
so that it (the releasing appliance) may easily and comfortably be found by the
thumb of the right hand and be acted on thereby at the same moment when the
hand is in position for firing.
The invention is shown in Figure 1 of the accompanying drawings as applied
to an ordinary double barrelled "Lefaulcheux gun. Figures 23 and 4 show
modifications in Figure 1 is the back end of the barrel and the two fixing
plates or tangs of samme s is the rod which holds the hammer or cock in position
and d d are the ordinary triggers.
The safety appliance consists of the pawl or trigger hook a which has its fulcrum
in bracket baud by the springs c is held in the position shown, in which it
prevents all movement of the trigger d.
The releasing appliance consists of a spring e with projection e' and the button
screwed in from above.
It is obvious that by pressing on, the button of a turu to the left of the trigger
hook a and the releasing of the trigger & follows in like manner by lifting the
trigger on the button said trigger is again held fast and the discharge of the gun
can only take place by simultaneously pressing the button e and the trigger d.

page_text: In Figures 2, 3 and 4 a few simplified modifications of the invention are shown.
The corresponding parts of the construction are in these drawings marked with
the same letters as in Figure 1 and the working and construction of which will be
understood without further description.
It will be seen that several similar modifications may be easily effected and
also that other construction of fire-arms would require other and sometimes
considerably different arrangements of the individual parts without changing the
principle of the invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
In firearms the employment of a safety trigger hook a which normally locks
the trigger but which in firing the gun can easily and conveniently be unlocked
or released by pressing on a button e³ or other suitable presser situated on the top
of the gun stock and thereby admitting of the discharge of the gun in the
ordinary manner.
