COMPLETE SPECIFICATION.
Improvements in Magazine Small Arms.
I, PETER JENSEN, of 77, Chancery Lane, London, Chartered Patent Agent, do
hereby declare the nature of this invention a communication; to me from the "Krag
Jörgensens Geverkompagni," of 10, Kongensgade, Christiania, Norway, Manu-
facturers, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:
.
-
These improvements refer to the construction of magazines for small arms with
fixed magazine and are shown in the accompanying drawings of which
Fig. 1 is side view of the gun mechanism and magazine the latter partly in
section.
Fig. 2 is a plan view.
Fig. 3 is a cross section on line x-x Fig. 1.
Fig. 4 is a cross section on line y y Fig. 1.
Fig. 5 is a cross section through the breech bolt casing on line z-z Figs. 1 and 2.
Fig. 6 is plan view of same from below.
Fig. 7 is side view of the magazine itself.
Figs. 8 and 9 are front and rear end views of same.
Fig. 10 is plan section of same, and
Figs. 11 to 16 are detail views.
Referring to Figs. 3 and 4, 2 is a steel plate sloping downward from the breech
bolt casing 1 and forming one side of the cartridge magazine; 2 is the upper part
of the trigger guard 4 Fig. 1 and forms the hollowed out bottom of the magazine;
the magazine further consists of the other side wall 5 and the end walls 6 and 7,
Figs. 7, 8 and 9. The end walls have notches 8 and 9, and the magazine is inserted
in the rifle by pushing it in a slanting direction along the plate 2, so that the
lugs 10 and 11 Figs. 1 and 6 enter respectively the notches 8 and 9 in the magazine
and thus hold it firmly in the position shown in Figs. 3 and 4. The magazine is
provided with a lid 12 hinged on a pin 13 which is pushed in through the lid and
the two end walls of the magazine, see Figs. 2, 3, 4, 7, 8, 9, 13, 14, and 15. Below
this pin the side wall 5, of the magazine has, a, recess 14 containing a, spring 15
(Figs. 3, 4, 7, 10 and 11) which rests on its bottom lug 16, while its ends 17 and 18,
turn upwards. Upon these ends rest the lugs 19, and 20 of the lid 12 see Figs. 12,
13 and 14, so that the said lugs- when the lid is opened will depress the feathering
ends 17 and 18 of the spring 15. One end of the spring 15 has a knuckle 21 which
fits in a cylindrical recess in one part 22 of the angle lever 22 23 (Figs. 1 and 7)
that has its fulcrum in the end wall 6. When the lid 12 is open the ends 17 and 18
will be in the depressed position, and the knuckle 21 will hold the lever 22 23 in
the dotted position shown in Fig. 7, so that the cartridges can be dropped into the
magazine. But as soon as the lid 12 is closed the tension of the spring 15 will
again force the lever 22, 23, the cartridge feeder and therewith the cartridges a
upwards to the opening 24 (Figs. 1, 3 and 4) whence they can enter the breech bolt
casing and thence by the bolt be brought into the breech. But the opening 24
can be narrowed by a half round spindle 25 arranged lengthways of the breech
casing; this spindle can by means of an outer handle 26 be turned half round

page_text: so that the round part comes below (Figs. 2, 3, 4, and 16). The cartridges will
then not be able to enter the breech casing and the rifle then acts as a single loader.
The spindle 25 which lies in a recess 27, formed partly in the magazine and partly
in the breech casing (see Figs. 6 and 7) also serves to prevent the magazine from
slipping upwards. The spring 15 serves as stated to act on the cartridge feeder but
also to hold the lid 12 in the open and closed positions caused by the lugs 19 and 20
un the lid 12, which lugs take their place respectively on the outer side of the
spindle or just under it in which latter case they depress the spring 15, see Figs. 3 12
and 14. The magazine lies quite hidden in the stock, the curved lid 12 only being
visible, and there are no projecting parts which come in the way during the
manipulation. The cartridges can be very conveniently dropped straight down the
magazine, so that no special operation is required while loading. The magazine
is detached from the rifle by merely withdrawing the spindle 25 and then sliding
the magazine upwards and out of the lugs 10 and 11. The several component
parts of the magazine come apart by merely withdrawing the hinge pin 13 as will
be understood from Figs. 3, 4, 7, 9, 10, 12, 13 and 14.
Having now particularly described and ascertained the nature of the said
invention as communicated to me by my foreign correspondent and in what manner
the same is to be performed I declare that what I claim is:-
―:
1. A magazine small arm the magazine of which consists of a steel plate (2) let
into the stock, and forming one side wall, while the other side wall (5) has an
upper recess in which lies a flat spring resting on a lower lug and having its
upwardly feathering ends abutting against two lugs on the magazine lid (12)
hinged on a pin, so that the spring serves to hold the lid fast in its opened and closed
positions, said spring with its knuckle shaped end fitting in a circular recess in one
part of an angle-lever-shaped cartridge feeder (22, 23) having its fulcrum in the
end wall (6) of the magazine, and the spring thereby so acting on the cartridge
feeder, that when the lid is opened and the spring bent downwards, the cartridge
feeder is swung downwards in order to permit the magazine to be charged with
cartridges while, when the lid is closed and the ends of the spring are again pressed
upwards; the cartridge feeder will act upwards and thereby force the cartridges
up against the breach casing substantially as set forth.
2. In a magazine small arm as firstly claimed the magazine inserted and held
in the arm by means of lugs on the breech casing fitting in recesses in the end walls
of the magazine and by means of a pin (25) inserted lengthways in a recess (27)
formed partly in the breech casing (1) and partly in the end walls of the magazine,
for the purpose of quickly detaching the magazine by merely drawing the pin
straight out and next drawing the magazine with all its component parts straight
up substantially as set forth.
3. The construction of magazine small arm shown on the drawing.
4. The construction of magazine shown on the drawing.
