Improvements in Sporting Rifles.
I, GUSTAV FÜKERT, Gun Manufacturer of Weipert in the Empire of Austro-
Hungary 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 improvements in question deal especially with an arrangement by means of
which the cases of discharged cartridges are automatically ejected, on loading
(opening) the gun; there is a further arrangement in this gun by means of which
the hammers, the heads of which only project beyond the lock, are cocked simul-
taneously with the opening of the gun, while at the same time the gun may be
cocked by hand as with those hitherto in use.
In the accompanying drawings the gun is shown in
Figure 1 in side elevation and in
Figure 2 in plan.
Figures 3, 4 and 5 are different views (and in both positions of the hammer) of
lock and lockplate detached from the gun.
Figure 6 shows the mounting of the mechanism by means of which the ejection of
the cartridge cases is accomplished and the double lever by means of which the self
acting cocking of the hammers is automatically effected.
Figure 8 shows the double lever.
Figure 9 displays three views of the fore end of the stock and stock-plate.
Figure 10 a view of ejection arrangement with part of the stock-plate seen from
below.
Figure 11 three views of ejection arrangement.
Figure 12 shows a detail of this arrangement and
Figure 13 a complete view on an enlarged scale with cover plate removed.
Figure 14 further details of this arrangement.
Figures 15, 16 and 17 show mode of action of the ejection mechanism.
Figures 18 and 19 show mode of action of double lever which effects the
automatic cocking of the hammers.
Figure 20 gives a perspective view of the stock-plate.
The lock in this gun is distinguished by the fact that the cover plate A covers
the hammers B in such a manner that the heads only of the latter project from it.
This on the one hand has the advantage that the hammers present no obstacles
either when the gun is cocked or uncocked so that the stock of the gun has in this
portion of it no projecting angles, while on the other hand the gases resulting from
the combustion of the powder a part of which around the nipple is forced outwards
in a backward direction, are made to pass directly into the air, without being able
to render the lock unclean as is the case with guns in which the hammers are
completely covered by the cover plate, further as compared with these guns and
the so called hammerless guns this one has the advantage of allowing one to sec
exactly which of the cartridges has been fired off. The hammer B and the
tumbler a are made in one piece, the latter being prolonged on one side into an
arm having a nose or projection c Figures 3, 4 and 5. d is the main-spring which
in the usual way is connected with the tumbler a by means of the link e and tends
to keep it in the uncocked position. The tumbler a is in the usual manner
provided with a full-cock notch and with a half-cock notch in the notches of which
engages the head of the sear which is pressed by the sear-spring f¹; the triggery
acts on the tail of the sear in the usual manner.
The tumbler a is mounted between the cover plate A and the bridle C. As with

page_text: other guns the hammers of which are actuated by the main spring, the hammer here
also automatically recoils into the half-cock notch.
By means of the above named arm band its nose e with the co-operation of
proper arrangements to be described later on the fired cartridges i.e. spent cartridge
cases are expelled from the barrel at the opening of the gun, and the latter is
cocked automatically.
The mechanism for the self acting cocking consists of a cocking lever E mounted
in the swing-plate D capable of turning round the pin h one end E' lying below
the arm while the other end E2 projects from the swing-plate D. This end E² of
the lever is set in a rectangular aperture of the stock-plate F Figures 18, 19
and 20. On opening the gun, i.e. on turning of the stock-plate F the end E' of the
corking lever E is carried along with it and turned down whereby the end E' is
moved upward and inasmuch as it acts below against the arm 6 this manipulation
also effects the turning of the tumbler a and of the hammer (as shown in Figure 18)
which is cocked according to the extent to which the gun is opened and if fully
opened, the hammer is turned so far up that the sear snaps home into the full-
cock notch. As the cocking-lever E does not hinder the movements of any of the
component parts of the lock, it follows that one can cock and uncock the hammers
without, as well as with, the co-operation of the lever.
The cartridge-case ejection mechanism consists of two parts of which one, the
ejection mechanism in the narrower sense of the word (the active part) is mounted
in the stock-plate the other (passive part) in the swing-plate of the gun.
This latter portion consists of three component parts (Figs. 6, 7 and 15—17) ;
1) A peculiarly shaped tumbler plate j
2) A second segment-shaped tumbler plate / and
3) A sliding stop or catch 1.
The tumbler plate j is pivotted on the pin j' and is provided with the curvilinear
opening its end 3 when in a state of rest (Figure 6) engaging in the notch k² of
the segment-shaped tumbler plate k which is pivotted on the pink and also
connected by means of the tooth with the sliding stop or catch (Fig. 7). The
nose of the arm 6 (Fig. 4) projects into the opening of the tumbler plate j in
such a way that when the hammer is cocked it is in about the position shown in
Figure 6.
When now the hammer is let go the nose c moves in the direction of the arrow 1
(Figure 6) till it strikes against the edge of the opening at a and thus effects the
turning of the tumbler plate j (in the direction shown by the arrow 2), this
movement being supported by means of a small spring (Fig. 6).
Through the motion of tumbler-plate j tumbler-plate k is also turned in the
direction of arrow 3 the tooth of which effects the forward movement of the
sliding stop (in the direction of arrow 4). When these component parts have
assumed about the position shown in Figure 7 this is maintained in such manner,
that when pressure is applied to the projecting end of the sliding stop (in the
opposite direction to arrow 4) as shown by arrow 4', it cannot possibly cause it to
slide back inasmuch as tumbler plate k abuts (crosswise) against tumbler plate j
so that no force however great can produce a motion in this direction. The
mechanism returns to its original position by means of the hammer, which as
already mentioned is cocked by means of the lever E, at the same time the nose c
is moved in the direction of the arrow 11 (Figure 7) and by applying itself to the
margin of the hole at a¹ it effects the turning of tumbler platej (in the direction
of the arrow 21) and of tumbler plate k (as shown by the arrow 3¹) as well as the
drawing back of the sliding stop (indicated by the arrow 41 Figure 7).
The ejection mechanism is fixed in the stock-plate F by means of a screw in
(Fig. 11). It consists of a plate a pivotting about the bolt n' to which by means
of the hinge joints o' and pi two levers o and p are joined (Figs. 11, 12, 13). A
very strong two armed plate spring one arm of which is held by a fixed support q
while the other presses against the shoulder of plate a maintains the latter
continuously in the cocked condition.

The end p³ of the lever is thickened
The lever o turning around the hinge joint o' is pushed off the plate n constantly
by a weak plate spring while the nose t¹ of the framing piece t engages in the
opening o of the front end o³ of the lever o and maintains the plate spring in the
cocked position.
Above the lever 'the split cartridge extractor L is placed in the barrel.
The mode of action of this arrangement is as follows;-When one of the charges
is fired the sliding stop as already described is pushed forward (Figure 15).
On opening the gun the end of the sliding-stop thus pushed forward presses
against the end p³ of the lever p, which is accordingly forced to make Way for
it. The counter pressure of the sliding stop or catch on lever pacting in an
upward direction the latter must yield in this direction (as shown by an arrow
Fig. 16).
Any turning of the lever p around the hinge joint p' in this direction being as
hereinbefore explained impossible, it follows that the lever whose shoulder p³
presses against the shoulder n³ (arrow direction 1 Fig. 16) must cause the turning
of the plate n in the direction of the arrow II. The end o³ of the lever o is con-
sequently pressed against the cartridge-extractor in the barrel which being drawn
by the hook z (Fig. 15) is pushed forward a little in the direction of the arrow III
whereby the lever o is compressed in the direction of the arrow IV and in this
manner makes way for the cartridge extractor. With the further motion of the
plate n the lever o is turned so far that the end o³ clears the cartridge extractor,
and by the reaction of the spring s is as it were elevated.
At the same moment the end p³ of the lever p slips off from the projected end of
the sliding stop. The spring at once propels forward the plate n in consequence
of which the end o³ of the lever o thrusts the cartridge extractor back and ejects
the spent cartridge case.
In this way the whole mechanism returns to its original position, and as by
means of the cocking lever E the hammers are cocked at the same moment, and (as
appears from what has been said before) the rod is drawn back into its original
position, it follows that all the parts of the mechanism after the opening of the gun
resume their original position, with the exception of the cartridge extractor, which
is restored to its position of rest only after the closing of the gun by means of the
breech closing plate M.
The lever p can also be made of one piece with the plate n--it is only provided
with a hinge as above described, in order that in case the mechanism which effects
the cocking of the gun should fail, and the rod in consequence fail to be drawn
back from its forward position, the lever p sliding along the latter, may be pressed
back and yield to it, so as to get out of its way.
The Specification has had regard to one of the barrels only but it should however
be specially noted, that each of the two barrels possesses a separate and similar
mechanism, quite uninfluenced by the other and self-acting so that when only one
of the cartridges has been fired, on the opening of the rifle only the case of the
fired cartridge is ejected.
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. An arrangement in sporting rifles of the hammers B which are covered by
the lock plate A in such a manner that only their small heads project, the tumbler a
which is made of one piece with the hammers being provided with an arm b which on

page_text: firing and subsequent opening of the rifle is raised by a cocking lever E the pro-
jecting end E' of which is depressed by the stock-plate F in which manner the
cocking of the hammers is effected substantially as described and illustrated in the
accompanying drawings.
2. The arrangement in such rifles of a sliding catch or stop capable of forward
and backward sliding motion which on firing of the gun is pushed forward by the
nose e of the arm by means of the tumbler plates and as the plate / places
itself crosswise to the platej it is prevented from being pushed back by any force
which may happen to act on its projecting end and its position is thus fixed
substantially as described and illustrated in the accompanying drawings.
3. The arrangement in such guns underneath the stock-plate F of a tumbler
platen pivotting on or around the bolt n¹ the lever p of which plate is at the
opening of the gun pushed upwards by the projecting end of the sliding catch or
stop and hence effects the turning of the plate n this latter being after the lever p
has left the end of the sliding catch or stop propelled by the spring whereby
the lever o which has in the meanwhile arrived behind the cartridge extractor
effects the ejectment of the spent cartridge case substantially as described and
illustrated in the accompanying drawings.
