page_text: I, BENJAMIN JOSEPH BARNARD MILLS carrying on business under the firm or style
of Harris and Mills of 23 Southampton Buildings in the County of Middlesex,
Patent Agent do hereby declare the nature of my said invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
The invention relates to that class of magazine-guns known under the name "Mauser"
which are closed by a cylindrical breech-piece, and in which the cartridge magazine is
situated beneath and along the barrels. The construction of different parts of the
except in regard to the present new invention is covered by the English patents
Nos. 134381 and 210982.
gun,
The object of this invention is to provide better means than those heretofore used
for taking up the recoil and for securing the breech-chamber in its axial position when
the arm is fired.
In the accompanying drawing, forming a part of the specification the same letters
of reference indicate corresponding parts.
Figure 1 is an axial and horizontal section of the lock-case c.
Figures 2 and 3 are vertical cross-sections drawn on the line A B of Figure 1.
the chamber e being shown in the one case in the vertical position in the other in a
horizontal or closed position.
Figure 4 is an end view of the case c.
Figure 5 is a side view of the chamber ch, showing the recoil-shoulder zw.
To enable the chamber ch to take up better the recoil of the exploding cartridge and
to keep it more correctly in its axial position than has been possible by laying the
guide-bar ch² in closing the breech into the recess of the case and pressing the back
of the guide-bar ch against the recoil-face of the recess of the magazine-gun
Mauser" as heretofore constructed a second recoil-take-up
lifficulty was to find a place inside the case c where the necessary arrangements
made use of. The

he carrier and the recesses for the movements of the guide-bar ch² in the
ack-portion by the groove ns for the nose of the small-lock (the latter is not shown in
he drawing) and the recess for the sliding-block of the repeating-mechanism, and in
its whole length by the groove for the extractor o or the expeller j as the case may
be and by the opening for the reciprocating movement of the guide-bar ch².
The metal of the case e remaining between the groove and the grooves, is used
to constitute in combination with a shoulder zwe provided upon the chamber ch
at its back-end a second recoil-fake-up. For this purpose inside of the case ca
longitudinal groove is formed which allows the chamber ch with its shoulder zw
to be pushed completely into the case c, Figure 2. Further the metal of the case c is
milled out in an annular direction 2 in such manner that the chamber ch can be
thrown over to the right (Figure 3) in the recess of the case c, when the shoulder w
slides in front of the metal left standing between the grooves n s and forming with
this abutement a second recoil-take-up.
ミ
As the two recoil-take-ups form in radial direction an obtuse-angle with each other,
the axial position of the chamber ch, is maintained at the moment of the explosion of
the cartridge very effectually, so that the hitting security of a gun provided with this
improvement is much greater than that of the same gun without it.
I know that recoil-take-ups of different constructions are known and used on other
guns than those, called "Mauser" but as far as I know a second recoil-take-up of any
"Mauser" guns nor was the precise identical
construction was never used on
construction, described above, used or known at all.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
