Improvements in Magazine and other Small-arms.
1, PETER JENSEN, of 77, Chancery Lane, in the County of London, Patent Agent,
do hereby declare the nature of the said invention a communication to me froin
abroad by Ole Herman Johannes Krag, Director of the Royal Norwegian Gun-works
and Erik Jörgensen, Gun-Smith both of Kongsberg, Norway and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement :-
This invention consists chiefly in a new arrangement and construction of the
magazine and in the means for feeding the cartridges through the magazine in fire
arms with bolt or cylinder-breech piece and also in several improvements in the
construction of the lock itself.
The main object of this invention is to so arrange and construct the magazine, that
the cartridges may be inserted in the same with the greatest possible ease, so that
the magazine, when emptied by shooting may very quickly be refilled with
cartridges, but the object of our invention is also to simplify the construction of
the locking, loading and extracting mechanisms and other parts, as will hereinafter
be specified.
In the drawings:
Figure 1 is an isometric view of the improved mechanism, the locking parts being
drawn half way backwards, and the magazine lid being half way opened.
Figure 2 is a horizontal section through the breech-fraine or lock-case and the
halfway opened magazine-lid, to illustrate the working of this latter.
Figure 3 is a cross section through the lock-case and the magazine, looking from
the front.
Figure 4 shows the magazine lid with connections from the inside.
Figure 5 is a vertical longitudinal section through the lock-case and magazine.
Figure 6 is a vertical longitudinal section through the locking plug and connected
parts.
Figures 7-10 are details.
The magazine (Figure 1-5) consists of a thin casing 1, which fits to the lock case
and is secured thereto by means of screws underneath; it may also be secured to the
stock. The magazine-case is on the right hand closed with a lid 2, pivoted on the
pin, 3, and being on the inside provided with a mechanism, that serves to feed
the cartridges into the gun. This mechanism the peculiar combination of which
with the lid is the main part of our invention, consists of a lever 6, on the spoon-
like end 5, of which is pivoted a plate 4, swinging on the pins 7, and being on the
inside provided with a concave, curved surface. The feed lever 6, is pivoted on a
pin 8, secured in the lid and is acted upon by the downwardly projecting end 9,
of the spring 10, which is secured near the outer end of the lid, by means of the
head 11. This spring tends to push the lever inwards. But according to the position
of the lid the lever is more or less stopped in its inward movement by a knob 12,
which is secured to the magazine-case, and which rests against the other end 13 of
the feed-lever. It is evident, that by this arrangement the feed lever can only move
freely, being acted upon by the spring, when the lid is closed; the pivot 8 of the
lever is then situated at a Figure 2. When the lid is opened the knob, 12, will
act upon the lever and compress the spring, so that when the lid is swung at,
right angles with the gun, the parts will all be withdrawn close to the inside of
the lid.
The magazine opens into the lock-case on the left hand of the same, and the form
of the magazine-case is in plan parallelogrammic so as to conform with the arc-
movement of the feed-lever (Figure 2). On the left side (right side of Figure 3)
the case is curved forming about a half circle, so that the cartridges will be guided

page_text: by this curved wall up to the entrance opening into the lock-case. The entrance
opening (Figure 5) is at the forward end high enough to let the cartridges through,
but at the rear end the opening is only high enough to let the cartridges partly through
(as shewn in dotted lines at Figure 3).
In order that the feed lever 6, may be able to push the last cartridge into this
latter position, the hole in the lover in which the pin 8 is inserted is oblong in section
(as shewn in Figure 2), so that the lever may get an inclined position, and the plate 4
the position shewn in dotted lines at x, in Figure 3, whereby the end, 5, of the lever, 6,
has pushed the cartridge out of the cavity of the plate 4 so that the cartridge will rest
on the upper edge of the plate.
When the bolt or cylinder-plug, 32, Figure 6 is moved forward from its hind most
position, the upper cartridge 6 will partly lie in its way and be taken forwards. The
front part of the same will be guided by the rounded surface, c, Figure 2 and when
the back of the cartridge reaches the point, d, (Figure 2) the whole cartridge will
jump over into the way of the cylinder and be pushed into the chamber.
At the rear end of the magazine (Figures 3 and 5) there is arranged a stopper,
by means of which the cartridges may be stopped from entering into the magazine,
when desired. This stopper is shewn by itself in Figure 8 and consists of a pin or
shaft 15 which is split at its forward end, and has a projecting spring-arm 17,
reaching into the magazine. This stopper inay by means of the arm 16 be turned
about 120°, so that the projection 17 either is turned downwards, as shewn in the
drawing, whereby the cartridges are hindered from entering into the lock-case or is
turned upwards being pressed against the top of the magazine, so that the cartridge
may pass underneath the same and be pressed into the position shewn in dotted lines
at ; the arm 16 of the stopper will then be turned in the position shewn in dotted
lines. The stopper is simply inserted into a hole in the left back part of the lock-
case, and this hole is made somewhat wider at the inner end, so that the stopper is
hindered from falling out therefrom, the compressible foremost part fitting, when
inserted tight into the widened hole.
The lid 2, of the magazine is locked in its closed position by means of a tooth 19,
on the spring 18, (Figures 3 and 4) which tooth engages with a tooth 20, on the
case or frame 1 of the magazine. The spring 18 is screwed to the top-part of the
lid and is moved upwards, in order to open the lid by means of the knob 21, the same
having an eye 22 projecting through a hole in the lid and engaging with the spring
through a pin 24, on the projection 23, on the spring. When the knob is pressed
outwardly, the same will turn on the edge e as a pivot and draw the spring upwards,
thereby disengaging the teeth 19 and 20, and the lid will swing outwards.
The construction of the lock, the cartridge-extractor, and firing mechanism is in
general similar to that used on several other gun systems with cylinder-lock but is in
some respects improved and is shown in Figures 1, 2, 6 and 7.
The nipple or firing pin consists of a cylindric part 25, which is provided with a
cock pull or thumb piece 26, that on its lower part has notches, 27 engaging with the
trigger, which latter may be of any suitable construction. The front part 28 of the
nipple is connected with the rod 25, in the manner shewn in Figure 6. The spring 29,
is laid between the rear end of the piece 28, and the bushing 31, projecting from
piece 30. The hollow cylinder (the cylinder plug) 32, in which these aforenamed
parts are inserted has on its rear end a collar, 33, stretching itself over about one third
of the circumference of the cylinder, and engaging with a notch in the projection 34,
of the piece 30, which latter as it will be seen holds the cylinder and the nipple
together.
The cylinder has on the front end a heel 35, (Figures 6 and 7) and on the side
a rib 36 (Figure 1) serving as a stop for the cylinder, when this is being turned,
by means of the lever 38, about 90º.
The cartridge extractor consists of a spring 40 (Figure 6.), which may be made
in one piece with the projection 34, or as shewn pivotted to the same by means of
a bolt 39. The spring has on its front end a hook 41, and may also be provided
with an auxiliary spring, 42, which is fastened underneath the spring-arm, 40, on

page_text: one side of it. The spring arm 40 is provided on its front end on the side, where the
spring 42 is fastened with a notch g Figure 1.
In the heel 35 is inserted an axially movable pin 43.
The working of the lock is as follows:-
11
In Figure 6 the nipple and the cylinder are shewn in the position which they
have before the gun is fired off. The lever 38 has then a horizontal position; the
heel is turned down into the hole 44, and the rear surface of the rib 36, is in contact
with the horn 45.
When the gun is fired off, the forward projecting part of cock 26 (Figure 6) falls
into the notch 37, in the cylinder, so that, when after shooting, the bolt or cylinder
is turned, the curved surface of the notch will act against the aforesaid projecting part
of the cock 26 and put the spring in tension. Through this turning the cartridge
shell is also drawn a short distanco backwards, as the rear surface of the horn 45 is a
little curved as shewn at Figure 1 and acts as a screw surface against the inner part
of the handle 38.
The hook 41 rests, when the mechanism is locked, in the notch 18 Figure 5 but
slides now downwards and catches over the edge of the cartridge; the downward
tension of the spring 40 is increased by means of the auxiliary spring 42, the front
end of which rests against the tooth 49. The cartridge shell is now drawn backwards
until the heel 35 reaches the horn 45, in which moment also the little projection 47
at the inside of the horn 45, will touch the pin 43, so that the same will project on the
front face of the cylinder, and throw the shell out.
In the next moment a new cartridge will have sprung out into the way of the
bolt or cylinder (as at 6 Figure 3) and this cartridge will now be taken forwards as
already described.
The locking is performed through turning the handle downwards whereby the rear
surface of the rib 36 acts against the front surface of the horn 45, which surface is
also curved like the back surface as hereinbefore described, so that the cylinder is
pressed forwards, and the extracting hook 41 pushed upwards on the inclined bottom
surface of the notch 48.
In Figures 9 and 10 is shewn a box S, that serves to fill the magazine with
cartridges. The same is shewn in plan form above in Figure 9 and in front elevation
in Figure 10, and is cut out of a single piece of tin and bent together, so that it will
take up 5 cartridges. The box is open in front and closed behind by means of the
upward bent edge and on the sides and partly on the top closed with the laps K
and F. In the lap F is mounted a wire D with handle H and with the arms and d
which may be turned in two positions. In closed positions as in the drawing, the
arm will act as a stopper, so that the cartridges cannot slide out, but when
the handle is turned outwards, the arm d will push the cartridges outwards.
When the magazine is to be filled by means of this box, the same is placed in
front of the magazine-opening, the lid being opened and the handle H is turned
upwards so that the cartridges are allowed to roll into the magazine, the box being
held somewhat inclined. The magazine may also be filled by hand.
The gun as herein before described is most conveniently constructed with magazine
for 5 cartridges but the same may also be used as a single loader.
It will easily be understood, that the construction of the lock and connected parts
may be done in a great many the most different ways without affecting the principal
part of the invention, as it is the location, working and construction of the magazine,
which is the most important part of the invention, and which may without material
changes be combined with other constructions of locking devices. I do not limit
inyself to the specific construction of the magazine, and the devices connected
therewith as shown in the drawings.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed as communicated to me
by my foreign correspondent 1 declare that what I claim is :-
First In ກາ magazine ann a
magazine in the form of a flat box arranged

page_text: horizontally directly under the lock casing and having on one, the right side, an
opening closed by a laterally opening lid, while the other, the left side, curves up to
and in towards the lock terminating in a slot in the sidewall of the lock casing against
which the cartridges are pressed being pushed laterally forwards through the magazine
and by reason of the said upwardly curved wall are forced into the slot substantially
as set forth.
Second. In a magazine gun a lug 12 in combination with a lever which is con-
nected to the magazine lid and pressed inward by a spring and connected to a
lever 5, all operating in such manner that when the lid is swung out for enabling
fresh cartridges to be put in the lever 6 will be drawn back to the inside of the lid by
reason of the lug 12 pressing on the lever in a direction opposite to that of the spring
substantially as set forth.
Third. In a magazine gun the combination of the magazine 1 and a lid or cover 2
closing the same, with a cartridge-feeding mechanism consisting of a lever 6 pivotted
near one end, and a spring, acting to push the lever inwards into the magazine and a
stop acting on the other side of the pivot of the lever, when the lid is being opened,
so as to withdraw the lever to the inside of the lid, substantially as set forth.
Fourth. The combination of the lever 6, having a spoon shaped end 5 with the
plate 4, pivotted on the same end 5 for the purpose set forth.
Fifth. In a magazine the lock for the magazine-lid consisting of the spring 18,
teeth 19 and 20 and knob 21.
Sixth. The combination with the magazine and cartridge-feeding mechanism of the
stopper 15, 16, 17.
Seventh. The construction of the cartridge-box of a single piece of tin in combination
with the stopper-shaft D, Figures 9 and 10.
Eighth. The construction of the lock consisting of the cylinder 32 and the firing
pin 25 connected by means of the pieces 30 with the bushing 31.
Ninth. The combination of the extractor-hook 41, with the tripper 43 and the
horn 45.
Tenth. The construction of gun shown on the drawings.
