Safety Appliance for Small Arms and Sporting Guns.
We, FRANZ NEUBER, of Vienna-Neustadt, Neunkirchnerstrasse No. 42, Lower
Austria, Gunmaker, and JOSEPH TAMBOUR, of II. Mathilden Platz No. 5, of
Vienna, Austria, Gentleman, do hereby declare the nature of this invention
to be as follows:-
i
Safety appliances commonly fitted to small arms and sporting guns consist
generally of a movable stop in the lock acting only on the trigger, which stop
is moved into the safety position either by the act of cocking the hammer or by
a special movement of the hand, and is withdrawn from this position before
the gun is fired. This device has the disadvantage that in double-barrel guns
both triggers must be set free at the same time, so that when no shot or only
one shot has been fired either the gun must remain unstopped, or the stop must
be set again in the safety position.
The present invention relates to a safety appliance which acts not only on
the trigger, but also on the sear lever and comes into play automatically after
the hammer has been cocked, while it is put out of action as soon as the gun is
grasped in position for firing.
For this purpose there is inserted in the lock of the gun a stop which is auto-
matically pressed into the safety position by a spring and in this position
engages with the trigger and the sear lever. The withdrawal of the stop from
the safety position is effected by the hand pressing upon a lever, to which the
stop is linked, when the gun is grasped for firing.
Fig. 1 shews a safety device constructed according to this invention as applied
to a double-barrelled gun having push triggers and a pistol grip, while Fig. 2
shews the device applied to a similar gun having ordinary triggers and a stock
with no grip. Fig. 3 is a cross section through the safety stop and the
triggers.
The safety appliance consists of a stop c placed in a bracket a projecting up
from the trigger plate b. The front end of this stop, when it is acting as a
stop, presses on the arm d of the bar e of the sear lever, while a projection f
on the sides of the stop c presses on the arm y raised by the trigger, so that the
sear cannot be released either by pressure on the trigger or by an accidental
blow on the barrel.
The stop is linked to a bell crank h pivotted to the trigger plate. In the
form shewn in Fig. 1 the other arm of this bell crank h is linked to the arm i
of the lever k which is pivotted at j.
In the form shewn in Fig. 2 the other arm of the bell crank h is linked to a
projection m on one end of a bar the other end of which carries a second
projection n linked to guide arms o. In both forms the stop c is held in the
safety position by the pressure of a spring acting on the lever k or bar 7.
When, however, the stock is gripped for firing, a pressure is applied to the
lever or bar and the stop c is drawn back so that the trigger and the sear e

page_text: are liberated and the gun can be fired. When the pressure on k or is relieved,
the gun is again locked by the automatic return of the stop c.
To allow the sear e to engage when the gun is being cocked the key r moves
an arm 9 which, when the key is turned, pushes back the stop c and liberates
the arm d of the sear. The triggers and the lever k or bar are protected by a
double shield s.
Safety Appliance for Small Arms and Sporting Guns.
We, FRANZ NEUBER, of Vienna-Neustadt, Neunkirchnerstrasse No. 42, Lower
Austria, Gunmaker, and JOSEPH TAMBOUR, of II. Mathilden Platz No. 5, of
Vienna, Austria, Gentleman, 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: —
The safety appliances commonly fitted to small arms and sporting guns con-
sist in most cases of a sliding piece in the breech mechanism which only acts
upon the trigger, and which on cocking the gun is either automatically brought
in to the safety locking position, or is subsequently moved into the same by
hand; when it is desired to fire, the slide is first moved back out of the locking
position. This arrangement has the disadvantage that with double-barrelled
guns both triggers are set free from the safety device at the same time, so that
if it is only desired to fire the one barrel, the trigger of the second barrel
remains unsecured in the cocked position.
The present invention relates to a safety appliance which not only has the
property of acting both upon the trigger and on the sear lever of the hammer
and is automatically put in action on the cocking of the gun, but which is also
so arranged that the freeing of the lock is effected as soon as the stock of the
gun is grasped in being raised into firing position. On the other hand, any
accidental freeing of the lock when the gun is being carried in any position
while cocked, or when the gun is let fall, is effectually prevented.
On opening the breech mechanism the safety slide is automatically moved
back so that the sear and trigger are set free, and the former can engage with
the rests of the hammer on cocking.
!
These results are obtained by so arranging the safety slide in the breech
mechanism as to be brought automatically by spring action into the locking or
safety position, in which it locks the sear or sears and the trigger or triggers,
while for bringing it into the freeing position the slide is connected by suitable
kinematically articulated devices with a disengaging piece upon which the hand
acts in grasping the stock of the gun when bringing it into the firing position.
We will describe the said invention with reference to the drawings filed
with our Provisional Specification in which Fig. 1 shews the arrangement
thereof for a'double barrelled gun with push or stud triggers and a pistol grip,
while Fig. 2 shews the application to a gun with ordinary triggers and ordi-
nary stock.
Fig. 3 shews across section through the safety side and the triggers.
As will be seen, the safety slide e, which is guided in the loop a of the trigger
plate b, bears in its normal position with its front end upon the arms d of the
sears e of the hammers and with lateral projection fupon the bars 9 of the
triggers, so that the sears cannot be disengaged from the rests of the hammers;
either by means of a pressure on the triggers or trigger studs; nor by a blow at

the cocked position the locking slide c is pivottally connected to an elbow lever h
pivotted to the trigger plate, which lever is in its turn pivotally connected in
the construction at Fig. 1, to the short arm i of a disengaging lever k, also
pivotted at to the trigger plate. In the arrangement at Fig. 2 the said lever
is replaced by a bar 1, pivottally connected by bracket m with the elbow lever h
and by a second bracket n with the guide links o.
In both arrangements the slide c is maintained in the safety or locking posi-
tion by means of a spring p acting on the disengaging lever k or bar l.
When bringing the gun into firing position, the hand in grasping the neck
of the stock presses upon the lever k or bar 1, thereby turning the elbow lever h
and withdrawing the locking slide c so as to free the triggers and sears, so that
the gun can be fired. As soon as the said hand pressure is released the slide c is
at once moved back by its spring into the locking or safety position.
The breech locking bar (of known construction) has a rearward extension q
which, when the said locking bar is slid back in the usual manner by turning
the key r, for unlocking the breech, is made to bear against the slide c and, in
forcing it back, to free the sears c, so that they can engage with the rests of the
hammers when these are being cocked.
The triggers or trigger studs and the disengaging device k or 1, are protected
by a double looped guards, the rear loop of which is of such a form as to allow
the fingers to be conveniently passed through it for grasping the stock.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
1. In safety appliances for small arms in which a safety slide effects the lock-
ing of the sear and trigger or trigger stud, the combination with the said slide
of a device for freeing the said parts consisting of a disengaging lever k pro-
jecting below the stock and protected by a guards, which lever is pivoted to the
trigger plate and has its short arm i pivotally connected by means of an elbow
lever to the safety slide c, so that on grasping the stock of the gun when in
firing position, the said disengaging lever is pressed inwards so as to draw the
slide backwards, while on releasing the grasp on the stock the entire safety
appliance is automatically moved back into the safety position by means of a
spring pacting on the disengaging lever, the safety appliance being on the
other hand capable of being moved back to allow of the cocking of the ham-
mers by means of an extension q of the breech locking bar, substantially as
described with reference to Fig. 1 of the drawings.
2. The modification of the safety appliance referred to in the first claim,
wherein the disengaging device is formed as a bar pivotally connected at one
end to the elbow lever hand at the other end to guide links o, substantially as
described with reference to Fig. 2 of the drawings.
