Improvements in Breech-loading Sporting Guns.
We, JOSEF KAISER, Engineer, of 15, Jüdeselberstrasse, Münster, Westphalia,
and ANTON SCHNEIDER, Gentleman, of Hachen, near Elspe, Westphalia, both in
the Empire of Germany, 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 breech-loading sporting guns whereby the simple fall of
the breech-block not only closes the cartridge chamber and by acting as a self-
cocker causes the gun to cock itself, but also acts as a safety mechanism; moreover,
after the weapon has been fired off, the gun is opened by a single handle, and the
cartridge drawn forward in readiness for complete extraction.
The loading and extraction is confined to the simplest possible actions, as
compared with the complicated processes in other modes of construction. Another
important advantage of the present lock consists in the fact that the safety
nechanism comes into action at the moment when the breech block is closed, so
that the numerous accidents due to the use of guns unprovided with safety
appliances in the chase are avoided.
In the accompanying drawing,
Figure 1 is a longitudinal section through the right barrel of the gun, when
cocked and at safety.
Figure 2 is a longitudinal section between the two barrels, and,
Figure 3 a longitudinal section through the left barrel. (Arrangement for
removing the safety bolt.)
Figure 4 is a section shewing a modification of the extractor.
After the cartridge has been inserted in the barrel C Figure 1, the breech
block A is lowered, and this causes the nose b, which is made in one piece with the
hammer a, which latter rotates on c in the breech block, to come into contact with
the notch of the trigger h. The trigger which is prevented from shifting by the
bolt, forces the hammer to rotate on c, and so to throw the spring d on the nose b
into tension.
The breech block A is kept in its position by means of a tongue n which
engages with the part 1 of the breech block; this mechanism will be fully described
hereinafter.
If the gun is to be fired off, and the cartridge ignited by means of the firing
pink, the safety bolt i, which is pressed into the locking position by the spring m
must be pressed aside to the right. This is effected through the agency of a small
lever or thumb plate placed at z. To keep the bolt in its new position, the
arrangement shewn in Figure 3 is made use of. By turning the lever which is
placed at z the safety belt is removed ready for firing and is at the same time held
East in its new position by the dropping of the little disc y which is furnished with
a nose, into engagement with the spring a which is secured to A, until, by the
opening and raising of the breech block Å the spring x is taken off and the disc y
8 forced back by the spring m Figure 1 into its old position in which it prevented
he trigger from moving. In order to secure the breech block A which revolves
on the joint D Figure 2, in the position in which it closes the barrels or to open
he breech block after firing, as the case may be, and to effect the partial extraction
of the cartridge, the mechanism shewn in Figure 2 is made use of.
If, after the gun has been fired, a lever which is horizontally attached to the

page_text: bolt o which rotates round its own longitudinal axis be depressed, the part o' which
is attached to the bolt o (Figure 2) is thereby turned to the left and presses the
tongue n to the left out of the recess of the breech block A.
The spring g which lies upon the sliding extractor e and is thrown into tension
when the breech block is depressed, forces the breech block A which rotates
round D upwards. The nose with which the spring g is furnished and which lies
upon the slide e thereby pulls upon the nose of the slide e and draws it forward.
The upper part of the slide e forms a portion of the inner wall of the barrels. By
the drawing forward of the extractor e upon its guides f the cartridge, the head of
which rests against the extractor e, is partially drawn out of the barrel and can
easily be removed.
After the tongue n (Figure 2) which slides in guides u has been moved to the
left for the purpose of opening the breech block the oscillating catch q which
rotates round r, has its right side pressed upward by the spring p attached to the
tongue n and comes to lie in front of the guide u, thus preventing the tongue n from
being brought back into the closing position by the springs t which are thrown into
tension by the lug when the tongue n moves backward. At the same time the
catch g drives a pin S upward.
The closure is effected by causing the part of the breech block in which the
recess is formed to press down the pin S in its descent, the right hand end of
the catch a being thereby removed from the face of the guide u. The compressed
springt now by means of the lug v presses the tongue n to the right, the tongue
engages with the recess and thereby retains the breech block in the position in
which it closes the gun.
That the extractor e may be able to draw out with ease even cartridges which
have jammed a lever e¹ is rotably attached to the extractor e the upper part of this
lever obstructs the nose of the extractor spring g when the lever endeavours to
force the spring upward. Since the lower part of the lever e¹ applies itself to
the extractor-guide fit readily moves the whole extractor outwards.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. A breech-loading sporting gun having an upwardly opening breech block,
characterized by the following arrangements :-
a. A hammer rotably attached to the block and depressed by a hammer
spring also attached to the block, the hammer coming into contact with the
trigger by means of a projection, and thus throwing the trigger spring into
tension.
b. A trigger, the end of which is loaded by the hammer as described in the
first claiming clause, and is held in position by a locking lever which is
supported by a projection.
c.. An extractor spring attached to the block, which takes up a position behind
a projection of the extractor when the block descends, and is thrown into
tension so as to draw the extractor back when the block rises.
d. A locking device for the block consisting of a spring actuated tongue na
movable catch 9 and a pin S which moves through the block shifts the catch
and allows the tongue to engage.
2. An upwardly opening breech block in which as the block descends and closes
the breech the extractor spring g is thrown into tension so that it draws the
extractor back when the breech is opened.
2a. A special mode of constructing the extractor characterized by the fact that
the extractor spring 9 engages with a lever which is rotably attached to the extractor,
and abuts at one end on the extractor guide f and thereby facilitates the extraction
of the cartridge.
3. The arrangement of the hammer in the block in such a way that it has a
horizontal arm which comes into contact with the trigger.

page_text: 4. A spring safety bolt i which lies against the upper end of the trigger and can
be turned aside by a lever or thumb plate.
5. The improved breech-loading sporting gun herein before described with
reference to the accompanying drawing.
