Improvements in Automatic Fire Arms.
We, GEORGES ROTH, Manufacturer, and KARL KRNKA, Engineer, both of
o. 50, Rennweg, Vienna, Empire of Austria, do hereby declare the nature of
ur said invention and in what manner the same is to be performed, to be parti-
ularly described and ascertained in and by the following statement:-
The present invention relates to that class of automatic fire arms in which a
liding barrel is provided and cooperates to utilize the recoil for ejecting the

onnection with pistols, rifles and guns.
The invention consists of the details of construction herein after set forth
and particularly pointed out in the claims:-
In order to render the present specification more easily intelligible reference
is had to the accompanying drawings in which similar letters of reference denote
similar parts throughout the several views:-

closed and the firing pin after release. Fig. 11 is a detail view showing the
means for locking the cover of the magazine in position, Fig. 12 is a plan of
an improved frame for supporting the cartridges previous to inserting them
into the magazine and Figs. 13 and 14 are vertical sections through the same
showing the parts in two different positions.
The first part of the present invention relates to the peculiar construction of
the means for coupling the breech block and barrel, which is effected in such
manner that the breech block will not be uncoupled from the barrel until the
backward movement of both, due to the recoil, has taken place and whilst the
5 barrel is performing its forward movement. This arrangement effectually pre-
vents the gases of combustion from firing out at the rear when the breech is
opened.
:
Referring to Figures 1 to 4 and to Fig. 7:-The cover or housing 1 con-
taining and supporting the barrel 11 and the breech block 13 is attached to the
0 stock or handle 4 of the weapon by means of the hook 2 at the front and fits
into a groove 8 at the back or butt end 5, gripping over the said butt by means
of a hook 3. The front boring of the said housing is large enough to receive
the barrel 11 and the recoil spring 12, the said barrel being provided with an

page_text: enlarged rear end 11°, which fits into and is capable of sliding in the enlarged
rear boring of the said housing. The boring of the barrel 11 is enlarged
(Fig. 3) at the rear end to receive the front end of the breech block 13 and it
is provided with an annular groove 30 having a cam like entrance groove 31
into which lugs 17 at the front end of the breech block pass and lock when
the said breech block is turned as herein after set forth. The lugs 17, two of
which are employed symmetrically arranged, are also provided with cam sur-
faces 32 (Fig. 4) which engage the cam grooves 31 of the barrel and effect a
partial turn of the breech block as the end of the same enters or leaves the
end of the barrel. The rear barrel end is provided with keys 14 (Fig. 7) which
slide in grooves 16 of the rear housing boring and the firing pin 9 is also pro-
vided with a collar having lugs 15 which also engage the said grooves.,16, so
that both these parts are not revoluble, but are only free to slide in the
housing 1. The internal rear end of the butt is provided with an inwardly
projecting guide pin. 6 to support the breech block spring 7, said spring being
supported at one end against the inside of the butt and at the other end in the
hollow firing pin 9. This spring not only operates the breech block when it
has been uncoupled from the barrel, but also serves to operate the firing pin,
when the weapon is discharged. The breech block 13 is of cylindrical con-
struction and provided with an internal annular groove 25 and a second internal
annular groove 28. Extending backwards from the latter and at either side
symmetrically arranged are two horizontally extending grooves 27, the said
grooves leading into the annular groove 25 by means of spirally wound grooves 26
and within these grooves two lugs 10 fast on the firing pin lie. It should be
mentioned that the annular groove 28 is merely formed for the sake of conve-
nience in cutting the longitudinal grooves 27 and the spiral endings to the
same and plays no prominent part in the operation of the breech block. Short
inlet grooves 29 are provided in the ends of the block 13 to allow of the inser-
tion of the lugs 10 of the firing pin, when the parts are fitted together. From
the above description it will be seen that when the block 13 slides on the
exterior of the firing pin, the moment the lugs 10 engage the spiral parts of
the grooves 26, 27 that said block will be turned axially according to the
direction of movement of the same along the firing pin.
The pivotally mounted trigger 18 is spring pressed by means of a spring 33
acting on a pivotally supported double arm lever 21, which engages the sear 22
in the following manner. The rear end of the lever 21, which is also acted on
by the spring 33 (Fig. 1) fits as a sort of ball and socket joint,
into the front end 23 of the pivotally supported sear 22. The latter
is made in two parts both supported on a common pivot 22b, the
front part 23 having a spring housing at its rear end, enclosing à
spring 34 (Fig. 1 and 2) which normally depresses a tail 22 of the rear
part 22.
As will be seen from Fig. 1 this arrangement enables a lug 24 on
the firing pin collar to pass over the end of the sear on the rearward recoil of the
breech block, but, as the trigger is retained a moment by the finger, after the
recoil, the sear will be kept in such a position that the spring 34 [Fig. 2] will
force the rear end of the sear up under the lug 24 immediately the same has
passed over the said sear end and prevent the pin from again going forward with
the barrel under the influence of the recoil spring 12. Since the recoil takes
place instantaneously, immediately the weapon has been discharged, the trigger
cannot possibly be released before the lug of the firing pin has got behind the
end of the sear 22, the time being altogether too short.
The operation of the parts described, takes place in the following manner:-
Previous to discharging the weapon, the parts are in the position shown at
Figure 4, .e. the lugs 17 are locked in the annular groove 30 of the barrel
end, and the lugs 10 of the firing pin are at the rear end of the horizontal
part 27 of the groove 26, 27, the firing pin being retained by the catch of the
lever 21. As soon as the trigger is pulled, the lever 21 is tipped on its pivot

page_text: As soon as the
d the firing pin released, the movement of the said lever 21 lowering
ont end 23 of the sear 22 and raising the rear end 22 of the same into position
spring back into the path of the firing pin lug 24 as soon as the latter has
assed it at the recoil. On pulling the trigger the firing pin is free to move
orwardly because the lugs of the same were initially in the rear end of the
orizontal part 27 of the inner breech block grooves. As the recoil takes place
he sear end 22 yields, by means of its spring, until the lug 24 has passed it,
then it springs back and retains the firing pin in its extreme rearward position
lose to the back end of the butt at 5 as will be clear from Fig. 3. The barrel
however immediately commences to move forwards, under the influence of the
ecoil spring 12 and pulls the breech block with it as long as the lugs 10 of
the firing pin move in the horizontal part of the grooves 26, 27.
said grooves have been moved along the firing pin far enough to bring the said
lugs 10 into the spiral parts 26 of the grooves, the breech block will be partially
turned, which movement brings the lugs 10 into the annular groove 25 but
here the rotary movement of the block would cease as the lugs leave the spiral
groove, were it not for the fact that, at this moment, the block being detained
and the barrel continuing its forward movement, the cam surfaces 32 of the
forward block lugs 17 are caused to cooperate with the cam part of the groove 30
at 31 [the block having been turned far enough to bring the parts into co-
operation, by the action of the lugs 10]. This cooperation gives the block a
slight further turn just as it parts from the barrel and locks the lug 10 in the
annular groove 25. The block is now retained by the firing pin and the barrel
completes its forward movement alone [Fig. 3]. The cartridge is now forced
upwardly into the breech between the breech block and the rear end of the
barrel 11 in the direction of the arrow in Figure 3. By this time [all the fore-
going operations having taken place instantaneously], the trigger will have been
released and the sear 22 will, by the action of the trigger spring 33, be lowered
out of the path of the detent lug 24 so that the firing pin and with it the breech
block will move forward, under the influence of spring 7 until the front end
of the block meets the rear end of the barrel. Immediately this takes place
the cam surfaces 32 of the lugs 17 engage the cam or twisted parts 31 of the
grooves 30 and turn the breech block on the firing pin far enough to bring the
spiral grooves 26 into position in front of the lugs 10. The forward move-
ment of the block being arrested by the barrel, the firing pin will now move
forward in the said block turning the same and locking the lugs 17 in the annular
groove 30, the firing pin itself being arrested by the detent of the lever 21, just
as the lug 10 has gained the rear end of the horizontal groove 27, so that the
pin will be free to move along the said horizontal groove and to discharge the
0 weapon when the trigger is again pulled.
The second part of the invention relates to means for securing the weapon
against accidental discharge. In the present case a pistol is illustrated in which
the magazine is inserted into the handle from below and detained in position
by a detent pawl 36 which engages a notch in the magazine wall. The spring 37
45 of the detent pawl also fits into a recess in the rear of the trigger below its
pivot and as soon as the trigger has been released, i.e. the finger has been with-
drawn from within the trigger guard, the lower end of the trigger will be forced
up towards the guard so that the finger can only be inserted on pulling the

50 ends 19, 20 of the said trigger are lowered and, in order to prevent the lever 21
from being jerked, which might accidentally cause the weapon to go off, a
hook 40 on the trigger engages over the end of the same, as shown at Figure 1
and effectually prevents its upwards movement. Simultaneously a projection 38
at the front upper end of the trigger is raised by the action of the spring 37
55 and enters a notch 39 of the barrel, thus preventing the inward movement o
the same even if the muzzle of the barrel were accidentally struck against any
hinat

page_text: This mechanism is described for the purpose of the present application in
connection with a weapon having a removeable magazine and consequently a
magazine detent pawl, but in the case of a weapon having a permanent magazine
which is filled from the top and provided with a cartridge lifting device, the
detent pawl would of course be dispensed with and the spring 35 would simply
rest against a suitable part of the handle or butt, as will be readily understood.
The orifices 43 and 42 of the handle and butt are simply for the sake of
lightness and would be covered by the wood casing of the butt.
The third part of the present invention relates to the ejector mechanism,
which consists of the following parts:-The ejector spring arm 44 having
hook 45 is let in to one of the lateral guide ribs 14 at one end, its free end
extending into a groove 47 of the breech block. To the opposite side of the
breech block is attached the extractor hook 46. The parts operate in the
following manner:When the barrel and breech block recoil, they are locked
together as described and on their forward stroke the barrel is unlocked and
leaves the block, taking the ejector 44 along with it, as soon as the hook of the
ejector has advanced far enough it catches the rim of the cartridge case and
co-operating with the extractor hook 46 tips the cartridge case out of the breech
through the lateral opening 48 (Fig. 3). The ejector also serves to guide the
breech block in a straight line, between its rotary movements i.e. when it is in
the position shown at Fig. 3. This is effected in that the groove 47 is so formed
that at this moment the hook is in a straight part of the groove and thus pre-
vents the lugs 10 as afore described from entering the spiral grooves 26 before
the lugs 17 have engaged and entered the annular groove 30. At this part the
shape of the groove 47 is inclined (Fig. 1 & 5) and thus the hook allows the
block to rotate as far as necessary.
If
When the magazine has been exhausted the lifter or feed plate for the cart-
ridges may enter the breech between the block and barrel to enable the refilling
of the magazine in the well known manner, this part of the mechanism form-
ing no part of the present invention requires no further description.
however an interchangeable magazine is employed, the feed plate will be taken
out with the magazine and it would be necessary, when the magazine is replaced
to provide means for drawing back the breech block in order to allow the cart-
ridge to enter the barrel.
In order to effect this result a pivoted double arm lever 49 is provided at the
side of the housing 1, said lever having two arms 50 and 51 extending
through the wall of the housing into the interior of the magazine chamber 41
and the breech respectively. A spring 52 is provided at the opposite end of the
lever 49 said spring serving to normally keep the two arms 50 and 51 extending
into their respective chambers. Whilst there are any cartridges in the magazine
the arms will be held back out of the chambers by means of the said cartridges
or magazine pressing against the arm 50, as soon, however, as the last cartridge
has been fired, spring 52 forces the arms 50 and 51 into their chambers and
arm 51 will spring forward and prevent the breech block from coming forward
as shown at Figure 6. If the magazine is taken out and it is desired to close
the breech block nevertheless, this may be done by simply pressing the short
arm of the lever 49 towards the housing and thereby withdrawing the arms 50
and 51 from the interior of the housing.
If it is desired to open the breech to take out a cartridge or remove a cart-
ridge, which has hung fire, a slide 53, as shown in Figures 7, having button 54
is employed. This slide is guided in the side of the housing and capable of
movement towards the rear of the same when the button 54 is pressed in that
direction. The end of the slide, as will be seen from the figure extends into
the housing and engages a lug 15 of the firing pin. When the slide is pushed
back its end 55 engages the firing pin forcing the same into its rearward posi-
tion and as the spring of the barrel acts to force the same forward again, the
breech block will be unlocked and separate from the barrel so that the cartridge

arranged in the space 69. Each of the parts 64, 65 carries a forwardly extend-
ing lug 66, adapted to engage in lateral recesses 67 formed in the rear end of

pressed together by the fingers of the person manipulating the rifle, the said
lugs are so formed that they pass out of the lateral recesses of the cover and
allow the same to fall down around its hinge pin into the position shown in
dotted lines in Figure 10. The feed mechanism for the cartridges consists of 1
the pressure arm 70 pivoted to the inner surface of the magazine cover near the
front end of the same, a frame 71 also pivoted to the same pivot as the lever 70
and having an orifice through which the free end of the said lever extends. To
the free end of the frame plate 71 is hinged the cartridge carrier plate 72 on
which the cartridges rest. If double rows of cartridges are employed so as to
render the magazine less deep the carrier plate is formed with a corresponding

extending beyond its pivot is acted upon by means of the downwardly spring
pressed bolt 68 which tends to raise the free end of the same, which acts on

arrangement of the parts has a double advantage; in the first place it enables
the plate 72 to accommodate itself to the position and conicity of the cartridge,
which result has hitherto been attained by the aid of a second spring, and in
the second place the whole construction has the advantage, that when the cover
of the magazine is opened the whole feed mechanism falls down or collapses
against the cover as indicated in dotted lines in Figure 10, owing to the fact
that the short end of the lever 70 is removed from the sphere of influence of
the downwardly spring pressed bolt 68.
The arrangement further enables the magazine to be charged with separate
cartridges from beneath, which is a double advantage, because, this may be
done whilst one cartridge is already in the firing position within the breech.
After the last cartridge has been fired, the free end of the frame 71 will be
forced up into the path of movement of the breech block and prevent the same
from springing forward, retaining it back and thus enabling the re-charging
of the magazine.
The frame shown at Figs. 12 to 14 for holding the cartridges ready for strip-
ping off into the magazine is of improved construction and adapted to retain
the cartridges in position whilst in the frame, but to release the same when they
are to be pushed out of the frame into the magazine. With this end in view
the frame consists of the back 74 having sides with longitudinal grooves 77
The back is provided
which engage the cartridge ends in the known manner.
at about the centre with an inward depression 76 and with an interior loose
spring back strip 75 having its ends bent 1ound as at 78 and having a spring 79
attached at the back. The spring 79 is also provided with a central bulge
which, when the frame is full of cartridges is placed on the bulged part 76 o
the back as at Figure 13 and thus causes the inner back 75 to press the rim
of the cartridges against the ledge formed by the grooves 77 and thus preven
the cartridges from falling out. When the frame is placed at the mouth of th
magazine and the operator begins to push the cartridges into the magazine, th
loose back 75 recedes, owing to the projecting bulge of the same slipping of
the inner bulge 76 so that the bent round lower end of the loose back will reced
from under the lowest cartridge. At the same time all the cartridges will b
loosened and readily slid into the magazine.
Having now particularly described and ascertained the nature of our sai
invention and in what manner the same is to be performed, we declare tha
what we claim is:-
1:—In an automatic fire arm having a sliding barrel, the combination of

page_text: may be removed. In Figure 8 a modified form of the slide is shown, in this
case a bow 56 being provided which is let into the guideways 16 and provided
with hooks 57 at its forward ends engaging the lugs 15, the bow extending at
the rear of the housing so that it may be gripped and pulled out and thus be
caused to open the breech. Both these arrangements have the advantage that
they remain motionless when the weapon is being fired under ordinary circum-
stances.
In case the spring 7 should get broken or damaged or if the breech block,
for any other reason, should fail to come forward properly, a second slide may
be arranged at the opposite side of the housing, having the button arranged in
proximity to the lug 15 and extending with a hook into the housing so as to lie
at the extreme rear end of the same. This slide may be adapted to be moved
in the opposite direction to the slide 53 and thus if the breech block sticks at
the rear end of the housing, it may be drawn forward by means of this second
slide. The arrangement of the same will be selfevident and needs no illus-
tration.
Or the slide 53 may be formed round and have an axial movement which
may be caused to engage a lateral lug in a notch of the lug 15 and so if desired
couple the said slide to the firing pin lug as will be evident, in which case the
slide may also be employed to return the firing pin and breech block to the
forward position. It is not absolutely necessary that the hooks of the bow 56
engage the lugs 15 of the firing pin since they could also be made to engage
the guide ribs 14 or any other suitable part.
If the weapon is provided with a fixed magazine a cartridge retaining lever
will have to be employed, which allows the cartridges to be inserted from above
but prevents their springing out at the top-a device of this kind is shown at
Figure 9. This lever 58 is pivoted on trunnions 59 and extends into the breech,
being normally held with its front end in the breech by means of a spring
(not shown), which is inserted in the spring box 60 at the opposite end of the
lever. As the barrel returns after the recoil, it pushes the lever 58 aside and
passes it, and as soon as it has passed, the lever returns under the influence of
its spring and strikes the empty cartridge case, throwing it out of the breech
block laterally, through the opening 48, so that this lever may also be employed
as a substitute for the ejector 44 if desired.
When it is desired to remove the cartridge from the magazine, from above,
it is only necessary to press back the lever 58 by means of its button 60 and
the lifting or feed plate of the magazine will raise the cartridges up forcing
them out of the magazine into the hand of the operator.
Fig. 10 shows the adaptation of the improvements previously described to a
rifle, the breech block locking mechanism being exactly the same as also that
of the trigger movement and since similar numerals of reference are employed,
and the parts are merely modified in shape, no further description of the same
will be necessary, their operation being selfevident from the foregoing specifi-
cation. The safety device in connection with the trigger is omitted in the case
of the rifle. It may be mentioned that if the variable pressure points 19
and 20 are dispensed with the trigger 18 may be made in one piece with the
lever 23, in which case the lower arm of the lever 21 might also be omitted.
The rear wall 5. of the housing consists of a separate plate, since the handle
of the pistol is replaced by the butt of the gun.
The recoil spring 12 is omitted in Figure 10 because the same is advantage-
ously arranged at the front or muzzle end of the gun and may either be arranged
around the barrel or may be mounted in a special housing underneath the same
according to requirement. The rifle is provided with a fixed magazine and a
novel cartridge feed device, the said magazine being filled from the top with
the aid of a cartridge frame. Finally the present invention also embraces the
peculiar construction and arrangement of the magazine cover or closure and
the feed mechanism for the cartridges. The cover 63 is pivotally supported at the
