Figure 4 is a section on the line C. DE of Figure 1 showing the magazine in
position upon the gun.
Figure 5 is an elevation thereof seen from the left hand side.
Figure 6 is a horizontal section through the levers 7.
Figures 7, 8 and 9 represent the magazine fastened to the chamber of the gun in a
somewhat different manner from that represented at Figures 1 to 6.
The invention relates to a cartridge box or magazine which may be attached to or
detached, from the breech-piece of breech loading fire arms formed with cylindrical
breech blocks or locks for the purpose of changing so called single loaders in
emergencies into rapid fire arms.
In the drawing the magazine is shown attached to the well known "Mauser" gun,
but it may be used with other guns working with a cylindrical breech block or lock
with but trifling modification.
The magazine proper consists of alight boxa of sheet metal of trapeze shape, inclined
forward and of a cross section suitable to the cartridges used. It is essential for the
proper construction of the box a that a line vertical to and between the two narrow end-
sides is shorter than the length of the cartridges. From the amount of difference
of these two lines depends the forward inclination of the box a. Therefore the
drawing in this particular is to serve only as an example, and the shape of the box a

page_text: must be varied according to the size and shape of the cartridges to be used. The
box a is open at top, and is closed at bottom by a substantial frame work by which
it can be attached to the chamber c of the breech piece.
It contains a suitable number of cartridges, say 8 to 10, the projecting bases of
which are guided by grooves u provided at the rear on both sides of the box a
(Figure 2) the projectiles resting and sliding during their downward course upon
and along the inclined front wall of the box a. The cartridges are held parallel to
the opening of the box a and filled in from the open top one after the other with the
projectile foremost. The inwardly projecting spring of the box a is forced out-
ward in pressing in each single cartridge. This spring ¹ prevents the cartridges
from falling out of the box a if the magazine while detached from the gun is upset,
or if while attached to the gun, it is brought into the various positions which are
connected naturally with the handling of the gun. A spring for holding the
cartridges or for forcing them down is not used.
Between the horizontal part of the frame t and the body of the box a a frame h,
(the carrier) is interposed which is attached to the springs j, and can be moved to the
right for a distance sufficient to allow a cartridge contained in the carrier to drop
out of it into the cartridge rest of the chamber e of the gun. The shape of the
carrier is similar to the cross section of the box a and is of such dimensions as to
receive only one cartridge at a time.
For guiding the cartridge into the cartridge rest of the chamber e and for preventing
it from jumping out of the latter the springs are extended beyond the carrier h
forming the lugs . The springs j. j have the tendency to return the carrier h
to its normal position as soon as the power, which forced the carrier to the right
ceases to act. Upon the outside of the rear wall of the box a is fastened a guide f¹
for the slide block f which carries the angle lever 7 in such manner that it swings
horizontally round a pin secured to the foot k of the block f. In its normal position
the longer arm of the angle lever touches the left wall of the carrier h near its
centre. The shorter arm protrudes beyond the foot k to the right hand so far that
it can be acted upon by a nose m provided for this purpose upon the locking bolt o, as
will be described more particularly hereinafter.
Pi
The magazine is attached to the breech piece or chamber c in a simple but effective
manner. The bottom of the frame t is formed with two ribs or flanges q and
Figures 1, 4, 5 and 6, by means of which it is set astride upon the left wall d of the
chamber C, which is for this purpose reinforced and suitably shaped. In this position
the magazine is secured by two spring studs or catches e, e, attached to the outer
rib p catching into suitable indentations in the wall d. The studs or catches e, e,
extend from the longer arms of the levers r, r, which turn round the pins i and the
shorter arms of these levers work in an annular groove in the push-piece v. In a
recess bored in this push piece va coiled spring is enclosed which has the tendency to
force the push piece outward. Therefore the studs or catches e, e, are constantly
pressed inward.
By pressing the push piece v inward the studs or catches e are with-
drawn from the indentations in the wall d so that the magazine can be detached from
the gun.
It must be here remarked that the construction of the just described device may
be varied; for example, the spring catches or studs e e, may be attached to the wall d
and the indentations into which they catch may be formed on certain parts of the
magazine. This construction, an equivalent of the above described one is represented
at Figures 7, 8 and 9. The bottom of the frame t possesses two tennons b with
cross slots. The wall d of the chamber c is thick enough to permit two vertical holes
to be made therein, into which holes the two tenons b snugly. The catches or
studs e of the levers r, r, actuated by the push piece forced forward by the coiled
spring within it extend through suitable slots formed in the outside of the wall d into
the cross slots of the tenons b. In attaching the magazine the tennons b press outward
the catches or studs until the former are home when the latter will snap into the
cross slots and secure the magazine to it. A pressure exerted upon the push pieco v
makes the catches e recede so as to allow the removing of the magazine.

page_text: From the underside of the slide block f extends a short tenon 9 which will enter a
corresponding hole in the top of the wall d in case the slide block is pressed down.
A flat spring on the block catches with a sharp lip into a corresponding indentation
in the guide and secures the block f in this normal position, in which the arm l¹
can be acted upon by the nose m of the bolt o. If the slide block f is shifted upward
the lip of the spring will leave the lower indentation and engage at the end of the
stroke into another one of the guide higher up, securing the block in this position.
In this "dead" position, the arm is out of reach of the nose m of the bolt o and
the angle lever becomes immovable.
and
Before going further with the description of the working of the magazine, the
construction of the bolt o shall be explained as far as it is connected with the magazine.
Instead of the round check plate used heretofore a rectangular one n, Figure 3, is
employed. This plate n is provided with a nose n' which serves to check the back
stroke of the bolt by meeting a corresponding projection n² on the chamber
a second nose m in advance of the first one a¹ and on the left hand side of the plate n
is arranged to strike the arm if in its normal position. This action takes place a
little while prior to the finishing of the back stroke of the bolt o. During the
completion of the stroke the arm is by the nose m thrown backward and therefore
the other arm of the angle lever 1, moved out of its normal position to the right.
This motion of the arm causes the carrier h to swing to the right also, so that the
cartridge contained in the carrier can drop down into the cartridge resi. of the
chamber c. The following forward stroke of the bolt o pushes the cartridge into the
barrel of the gun.
After firing, the empty shell is pulled back by the extractor w
and expelled during the back stroke of the bolt o and prior to the striking of the
arm by the nose m so that the next cartridge dropping down out of the carrier h
finds the chamber c empty. These operations may be continued as long as a cartridge
remains in the magazine, after which the empty magazine is detached and another
charged one is attached or the empty magazine is filled with a new charge of
cartridges. To prevent the carrier h being moved too far, lugs s. s. projecting from
the carrier and working in corresponding grooves s of the frame t limit the motion
of the carrier by striking the ends of the grooves s' (Figures 2, 4 and 5). The
carrier is provided along the upper edge of its left wall with a rib 2 which during
the swinging motion of the carrier / supports the remainder of the cartridges in the
box a, so that a jamming of the carrier h by the next cartridge falling behind the
former is avoided. The opening of the carrier is made wider at the lower part
than at the upper part to facilitate the dropping out of the cartridges.
In case the magazine is attached to the gun but is not made use of and the gun on
the contrary is loaded by hand, the lever 1, 1 must be thrown out of gear. For this
purpose the slide block is pushed upward so far that the lip of the spring will
catch into the uppermost indentation of the guide . By this action the arm is
raised out of reach of the nose m now moving without effect below it. If the
magazine is to be made use of again the slide block f is pushed down bringing the
arm in reach of the nose m. The tenon y serves in this position of the parts to
receive the main portion of the blow caused by the nose m, striking the arm land
moving the frame and the cartridge in it, and relieving to a great extent the
frame and the catches or studs e. e., which parts, otherwise would have to sustain the
entire blow,
It may be remarked that the bottom of the cartridge rest of the chamber c may be
advantageously milled out a little deeper in the rear than in front and that just at the
front end of the opening of the chamber c a short shield x (Figures 3, 4 and 7) may
be provided for the purpose of securing the correct position of the cartridge
after being dropped out of the carrier A. But both these arrangements are not
indispensable.
The springs can be dispensed with and the carrier / can be connected by a hinge
to the arm which is driven by a suitably arranged spring to the left hand, so that
the carrier has the tendency to return to its normal position in the magazine after
having been forced to the right hand by means of the moving bolt o.
