PROVISIONAL SPECIFICATION.
Improvements in Safety Devices for Fire Arms.
I, THEODOR BERGMANN, trading as the Firm of Eisenwerke Gaggenau, at
Gaggenau, Germany, do hereby declare the nature of this invention to be as
follows:-
My invention relates to trigger-operated fire arms and has for its object the
construction of a safety device for preventing the untimely release of the hammer
or other firing mechanism.
In carrying out my invention I provide the fire arm, at that side of the trigger
opposite to where the finger for releasing the trigger must enter, with a guard or
lever, which is so placed that in order to permit the finger to take up its regular
firing position against the trigger said guard or lever must first be pushed aside.
This guard or lever is pivoted to a second lever pivoted to the side of the fire arm,
and provided at one arm with a spring and at the other with a projection or pin
which enters a corresponding hole or recess in the cocked hammer or other firing
agent of the weapon. The aforesaid guard or lever which is pivoted to the last
mentioned locking lever extends somewhat beyond the former, and with this
extension, which is rounded off or excentric, bears against the side of the
fire arm.
This
The aforesaid spring operates in such manner as to keep the parts in their
locking position. Thus, when the finger enters in front of the trigger it must,
before the trigger can be pulled, push aside the aforesaid guard or lever.
guard or lever being pushed aside, its extension, bearing against the side of the
fire arm, permits the locking lever to be raised against its spring, whereby the
locking pin attached to the arm of said lever is withdrawn from the hammer, and
the trigger may be pulled.
When the finger is withdrawn the parts under the influence of their spring
return into their locking position automatically.

COMPLETE SPECIFICATION.
Improvements in Safety Devices for Fire Arms.
I, THEODOR BERGMANN, trading as the Firm of Eisenwerke Gaggenau, Iron
Works, at Gaggenau, Germany, do hereby declare the nature of my said 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 trigger-operated fire arms, and has for its object the
construction of a safety device, for preventing the accidental release of the hammer,
or other firing mechanism.
In carrying out my invention, I provide the fire arm with a trigger guard, which
is so placed that it must be pushed aside in order to permit the finger to take up
its regular firing position.
And in order that my said invention may be particularly described and
ascertained, reference is hereby made to the accompanying drawings, in which
similar letters of reference indicate corresponding parts.
Fig. 1 is an elevation of the mechanism.
T

page_text: Fig. 3 is a plan view, partly in section, showing the cock secured.
Fig. 4 is an end view of the mechanism, at the moment of discharge.
a is a circular plate, fitting loosely the trigger opening. The plate a is attached
to a lever b, which is pivoted at n to another lever c. The lever is pivoted at d
to the side of the barrel. A spring presses outwards the short end of the lever c.
e is a pin attached to the long end of the lever c. This pin e enters a hole g formed
in the hammer when locked. The trigger is shown by a dotted line at k.
On placing the finger in the trigger opening, as shown in Fig. 4, the disc a is
pressed outwards. This operation causes the lever to move the lever c outwards,
as also shown in Fig. 4. The pine is thereby withdrawn from the hole g in the
hammer, and the piece is ready for firing. On the removal of the finger, the
levers resume their original position, as shown in Figs. 1, 2, and 3, whereby
the hammer is again locked.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In trigger-operated fire-arms, the combination therewith of a locking device
consisting of a disc a, levers b and c, the lever c carrying a locking pin e, entering a
hole in the hammer h, all severally operating substantially as herein before
described and illustrated by the drawings.
2. The general construction, arrangement, and combination of the several and
respective parts, together forming my invention of improvements in safety devices
for fire arms, substantially as herein before described and illustrated by the
drawings.
