PROVISIONAL SPECIFICATION.
Improvements in the Safety Mechanism of Breech-loading
Small Arms.
I, PAUL MAUSER, of Oberndorf on the Neckar, in the Kingdom of Wurttemberg
and Empire of Germany, Manufacturer, do hereby declare the nature of this
invention to be as follows:-
The present invention relates to improvements on a safety device described in
the Specification of Letters Patent granted to me dated September 30, 1889,
No. 15371, by means of which, if the gun is secured with cocked firing pin, it
cannot be fired, whilst if secured in the closed, but not cocked, state, the bolt
cannot be moved. According to my present invention, in lieu of making the "wing"
described in such Specification hollow and placing therein a sliding catch and a
cylindrical spring to force such catch outwards and securing the same in the wing
by a screw pin, I now form such wing and its shaft and spring catch of one piece of
metal, or the shaft may be made separate from the wing and spring catch and these
latter can be made in one piece and fixed to the shaft in any convenient manner.
The spring catch is formed of a piece or strip of metal extending from the wing
and coiled into the form of a loop or ring having on its free end a small lump or
catch which enters the recesses in the cylindrical portion of the safety device and
traverses a groove or against a shoulder formed around the same and extending
from one recess to the other; such spring catch may however have its free end
formed with a V shaped nose, in which case the recesses will be shaped to receive
the same and they may be in a direction towards the shaft of the wing or in a
direction parallel to such shaft; in the former case the spring catch will extend in
a semi-circle or thereabouts from the wing and will then extend in a straight line
towards the safety cylinder and will spring towards the same. In each case the
spring catch, by running in a groove or bearing against a shoulder, acts to keep
the safety shaft in its place in the safety cylinder.
The safety device thus improved will operate in precisely similar manner to that
described in my Specification hereinbefore referred to.

COMPLETE SPECIFICATION.
Improvements in the Safety Mechanism of Breech-loading
Small Arms.
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
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The present invention relates to improvements in a safety device described in
the Specification of Letters Patent granted to me dated September 30, 1889,
No. 15371, by means of which, if the gun is secured with cocked firing pin, it
cannot be fired, whilst if secured in the closed but not cocked state, the bolt cannot
be moved.
According to my present invention in lieu of making the wing described in such
Specification hollow and placing therein a sliding catch and a cylindrical spring to
force such catch outwards and securing the same in the wing by a screw pin, I
now form such wing and its shaft and spring-catch of one piece of metal, or the

page_text: shaft may be made separate from the wing and spring-catch and these latter can
be made in one piece and fixed to the shaft in any convenient manner.
In the accompanying drawing similar letters of reference indicate like parts.
Figure is a top view of the small lock with the safety device extending
horizontally, and
Figure 1 is a vertical cross-section in the dotted line 1-1 of. Figure 1 seen
in the direction of the arrow.
Figures 2, 24 and 2B represent a modification of the safety device in similar
views to those of Figures 1 and 14 and also a sectional side view.
Figures 3 and 34 show another modification of the safety device in views similar
to those of Figures 1 and 1*.
Figures and 4 show two views of the safety-shaft made separate from the
wing and spring-catch.
Figures 5 & 5A show a.modification of this latter construction.
The spring-catch e', which serves also as the wing or thumb-piece to turn the
shaft e, is formed of a piece or strip of metal extending from the back end of
the shaft e and coiled into the form of a loop or ring having on its free end a
small lump or catch e3 which enters the recesses in and traverses the groove d
upon the ridge d³ forming the socket of the shaft e.
This arrangement shown in Figures 1 & 1^. The spring-catch may however
have its free end formed with a V shaped nose e³ in which case the recesses will
be shaped to receive the same, and they may be in a direction parallel to the
shaft e as in Figures 2 and 24, or in a direction toward the shaft e as in
Figures 3 and 34 where the spring-catch e extends in a semi-circle or thereabout
from the shaft e and, terminating in a straight line towards the ridge a³, springs.
towards and into the annular groove d' of the same.
In each case the spring catch e', by running in the groove d², or bearing
against a shoulder (as in Figures 2, 24, & 2B,) of the ridge, acts to keep the
safety shaft e in its socket.
In Figures 1, 14; 2, 24, 2; and 3, 34, the spring catch e¹ or wing is formed
with the safety-shaft e of one piece of metal, but it may be made separate from
this shaft e and fixed to the latter by rivetting or screwing as shown in Figures 4,
4 and 5, 5, or in any other convenient manner.
The safety device thus improved will operate in precisely similar manner to
that described in the Specification of Letters Patent granted to me No. 15371
A.D. 1889, herein before referred to.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is: :-
1. In a safety device of the character and for the purposes shown and described
in the Specification of Letters Patent No. 15371 A.D. 1889, constructing the
safety-shaft e with a spring-catch el formed of a piece or strip of metal in the
shape of a loop or ring, serving also as a wing or thumb piece, the free end. e³ of
which traverses the groove 2, or bears against a shoulder upon the ridge d³, and
enters recesses of the groove d or of the said shoulder, substantially as shown
and described.
2. Forming the safety-shaft e with the said spring-catch e¹ of one piece of metal,
as in Figures 1, 14; 2, 24, 2B; and 3, 34.
3. In a safety device of the character referred to making the spring-catch e¹
separate from the safety-shaft e and fixing it to the latter by rivetting as in
Figures 4, 44, or by screwing as in Figures 5, 5^.
