page_text: I, PAUL MAUSER of Oberndorf, on the Neckar, in the Kingdom of Württemberg
and Empire of Germany, Manufacturer, do hereby declare the nature of this inven-
tion, and in what manner the same is to be performed, be particularly described
and ascertained in and by the following statement :—
The invention relates to breech-loading fire-arms with cylinder bolt, known as bolt
guns, of which the case opening is covered by the bolt guide.
And the object of the invention is to construct this kind of fire-arms in such way
that a temporary, or detachable, cartridge magazine can be arranged either on top of,
or below, the breech case of the gun and so that in either case the empty cartridge
shells are ejected automatically.
In the drawings;
Figure 1 is a left hand side view of the breech case.
Figure 2 is a transverse section on the line x. x. of Figure 1.
Figure 3 is a transverse section on the line y. y. of Figure 1.
Figure 4 is a partial horizontal section on the line z. z. of Figure 3 showing the
ejector in the state of being pressed back into the wall of the breech case.
Figure 5 is a partial horizontal section on the line z. z of Figure 3 showing the
ejector in its proper working place and in the act of ejecting a cartridge shell.
Figure 6 is a plan of the breech case partly in section showing in dotted lines the
arrangement of a magazine on top of the breech case.
The bolt is furnished at its back end with two recoil take ups or shoulders
entering into corresponding recesses of the breech case C as the bolt. k is locked by
moving to the right hand the hand lever on the end of the bolt k from its vertical
position into the horizontal one. This hand lever, which works along the back face
of the bridge B, and the recoil take ups are not shown in the drawing. If the bolt k
is unlocked by the reverse motion of the hand lever, one of the recoil take ups
enters into a suitable recess of the bolt guide f which forms one piece with the
bolt head F, and couples the bolt k with the bolt head F. The bolt k is shown in the
drawing only to such extent as is necessary for the understanding of the invention.
The bolt guide f slides between the walls of the breech case and below the bridge B
and, if the bolt k is locked, entirely covers the breech case opening. During the back

page_text: stroke of the bolt k, the stop d of the lever d' slides along the indentation a of the
bolt guide fand, abutting against the shoulder b, limits the stroke of the bolt k.
The claw of the extractor arranged in the bolt head F extracts, as usual, the
empty cartridge shell S out of the barrel. So far the construction of the parts is
either known or covered by other applications for patents.
If a gun of this kind of lock mechanism is intended to be used as a magazine gun
and if, for this purpose, a temporary magazine is to be attached, it is indispensable
to alter some parts of the gun. The cartridge expeller must be removed from the
bottom of the cartridge rest and a device provided to act at the proper time upon
the cartridge magazine, be the latter mounted on the breech case at its top or in
an opening in the bottom of the breech case. In the drawing is shown the
arrangement of parts best adapted for a magazine on top of the breech case, but
the place for a magazine below is also provided. The application of such device
is not shown in the drawing as it is very simple and offers no difficulty if the place for
it is provided.
The expeller is a flat piece of steel g with a nose g¹ and turns round a vertical
pin g. It works in a corresponding hole in the left hand wall of the breech case C
about level with the axis of the barrel of the gun. The pin 2, Figure 4, is in
one place flattened, in such manner that the arm m of the double spring m. m¹
secured to the outside of the breech case C presses the nose g¹ of the ejector g
into the bore of the breech case C if the bolt k is drawn back about fully, resting
during the other time with only little friction against the bolt k. To make easy
this coming forward of the nose g' and to facilitate the pressing back of it, if the
bolt is pushed forward, a sloping groove or recess is provided at the corre-
sponding place in the bolt head F, which latter, forming one piece with the bolt
guide is restrained thereby from turning, but can only slide along the bore of
the breech case C. The recess is deepest in front of the bolt head F. The claw r
of the extractor drags with it the empty cartridge shell S during the back stroke
of the bolt until the bottom of the shell abuts against the extractor nose gl,
which, at this time, protrudes about 5 to 8 millimeters into the bore of the breech
case C, Figure 5, as the bolt k goes fully back the shell S. is pulled back forcibly, at
the top of its flange, by the claw r, thrown around the latter and effectually
ejected.
By constructing the ejector in the manner just described, the bore of the breech
case, as far as it constitutes the cartridge rest is smooth and left unoccupied by grooves,
so that the lower part of it may be cut through for the insertion of a cartridge
magazine of the "Lee" type, the detail construction and working of which is so well
"known that a description thereof is unnecessary.
If a cartridge magazine be used which has to be attached on top of the breech
case, the top face of the left hand wall of the breech case C is provided with the
holes . . for the reception of the tenons of the magazine frame, as shown in Figure 6.
The magazine may be also united to the gun, (this arrangement is however not shown
in the drawings), by two flanges embracing the wall of the breech case C and secured
by locking bolts or latches entering recesses in that wall, as is described and shown,
as also the detail construction of the magazine in the specification of Letters Patent
granted to me dated November 26, 1887, No. 16274. The only alterations which are
made in this magazine are in the shape of the short arm of the elbow lever
actuating the cartridge carrier h, and the means to set in motion this elbow lever 1, 1.
at the proper time.
1.
Along the left hand edge of the bolt guide fa recess c is milled out, terminating at
the front end in a sloping shoulder c¹. During the greater part of the back stroke of
the bolt k, and therefore of the bolt guide f, the nose n' of the push lever n slides
along motionless in the recess c, but near to the end of the stroke the shoulder c¹
forces the nose n¹, and therefore the front end of the push lever n, outwards, as the
latter swings at its back end round a pin n². By these means the short arm l' of the
elbow lever 1, 1, which is always in contact with the push lever n, is turned round so
that the long arm pushes the carrier to the right hand whereby a cartridge is dropped
l

page_text: into the cartridge rest. As soon as the bolt is pushed forward again the push
lever n,
and therefore the elbow lever 1, 1, and the carrier return to their normal
position. The push lever n rests in a suitable recess in the outside of the breech
case C, the nose n working in a corresponding hole in the latter. The pin n²,
Figure 1, 4 and 5 is in one place flattened, in such manner that the arm m' of the
double spring m, m', mentioned also above, presses the nose n¹ of the push lever n
through its hole into the recess c of the bolt guide f.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what 1
claim is :-
In breech-loading fire-arms with cylinder bolt, characterized by the breech case
opening being covered by the bolt guide ;-
1. The cartridge expeller g with nose arranged in the side wall of the breech
case and obtaining, by a spring m working against a suitably flattened part of the
pin g of the expeller g, the tendency to protrude into the bore of the breech case (}
substantially as described and shown and for the purpose set forth.
2. The combination of such cartridge expeller g, possessing nose g', with the bolt
head F having the sloping groove or recess g³ corresponding to the nose g¹ of the.
expeller g substantially as shown and described and for the purpose set forth.
3. The push lever n with nose n¹ obtaining, by a spring m¹ working against a
suitably flattened part of the pin n² of the push lever n, the tendency to protrude
through the wall of the breech case C in to the recess c and within reach of the
sloping shoulder c¹ of the bolt guide fin combination with the elbow lever ll. of a
suitably constructed cartridge magazine united temporarily to the gun on top of
the breech case C, substantially as herein shown and described and for the purpose
explained.
<<
"
4. The removing of any obstacle out of the limits of the cartridge rest of the
breech case C and the use of this place for the arrangement of a so called
Lee
cartridge magazine from below through an opening in the breech case C substantially
as explained.
