New or Improved Safety Mechanism for Sporting Guns and other
Small Arms.
We, GEORGE BRAZIER, of 29, Hawthorne Road, Blakenhull, Wolverhampton,
in the County of Stafford, Gun and Rifle Lock Maker, and WILLIAM CASHMORE,
of 1:30, Steelhouse Lane, in the City of Birmingham, Gun Manufacturer, do
hereby declare the nature of this Invention to be as follows:-
This Inventionu consists of the herein described new or improved safety
mechanism for sporting guns and other small arms. By our Invention we БО
lock the sear in full bent (that is when the gun is cocked) that it is impossible
for the sear to jar off and release the hammer or striker unless the trigger is
pulled.
In carrying out this Invention we provide a safety lever which is arranged
underneath the sear. This safety lever is a short two armed lever turning on
a fulcrum piu situated at a short distance behind the fulcrum pin of the sear.
One arm of this safety lever is made as a tooth arranged to engage in a notch
which we form in a downwardly projecting part of the sear situated preferably,
though not necessarily, immediately under the fulcrum pin of the sear.
other arm of the safety lever projects backwardly and has a side projecting piece
which is situated alongside of the usual similar side projecting piece of the sear
so that both the sear and the safety lever will be lifted by the trigger blade when
the trigger is pulled.
'The
When the gun is cocked to full bent and the sear is engaging with the usual
notch in the tail piece of the hammer or striker, and maintaining the hammer
or striker in its cocked position, the tooth or projection of the safety lever engages
in the said notch of the sear and renders it impossible for the sear to be lifted
without first lifting the tail end of the safety lever so as to turn the tooth end
of the safety lever out of the notch of the sear. It is thus quite impossible for
the scar to jar off and release the hauuuer or striker unless the trigger is pulled.
When the trigger is pulled the trigger blade first lifts the tail end of the safety
lever very slightly so as to free the toothed end of the locking lever from the
notch in the sear, thus unlocking the sear and allowing it to lift as the pulling
of the trigger is continued.
The forward arm of the locking lever may if preferred be continued to the
tail part of the hammer or striker so as to act as an interceptor and come between
the bridge plate of the lock and a side projecting part of the tail end of the
hammer or striker when the latter is cocked so that, if the front end of the rear
or the notch in the tail ond of the striker should become so worn as to allow the
hammer or striker to go off, the said projection of the tail part of the trigger
will como into contact with the fore end of the interceptor and thus prevent the
hammer or striker from firing the cartridge.
It is to be understood that this Invention is applicable to all kinds of gun
locks for single barrel or double barrel guns and other small arms whether the

page_text: said gun locks are made with hammers or are such as are known as "hammer-
less," and that our invention is applicable both to single trigger and to double
trigger double barrelled guns.

New or Improved Safety Mechanism for Sporting Juns and other
Small Arms.
We, GEORGE BRAZIER, of 29, Hawthorne Road, Blakenhall, Wolverhampton,
in the County of Stafford, Gun and Rifle Lock Maker, and WILLIAM CASIIMORE,
of 1:30, Steelhouse Lane, in the City of Birmingham, Gun 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:
This Invention consists of the herein described new or improved safety
mechanism for sporting guns and other small arms. By our Invention we 80
lock the sear in full bent (that is when the gun is cocked) that it is impossible
for the sear to jar off and release the hammer or striker unless the trigger is
pulled.
We will describe this Invention by referring to the accompanying drawings
on which Fig. 1 is a side elevation of the lock of a double barrel gun with our
Invention applied the parts being represented in the positions which they occupy
when the gun is cocked; Fig. 2 shews the same parts as Fig. 1 with the back
trigger pulled slightly so as to unlock the sear ready for releasing the hammer
as the pulling of the trigger is continued; Fig. 3 shews the same parts as
Figs. 1 and 2 in the positions which they occupy after the gun has been fired;
Fig. 4 is an elevation and plan of the locking lever part of the said mechanism
and Fig. 5 is a frout elevation and plan of the sear; Figs. 6 and 7 shew our
Invention applied to another gun lock in which the hammer spring is arranged
in a different manner to that shewn in Figs. 1, 2 and 3 the parts being represented
in Fig. 6 in the positions which they occupy when the gun is cocked and in Fig. 7
in the positions which they occupy after the gun has been fired.
The same letters of reference indicate the same or corresponding parts in all
the figures of the drawings.
A is the usual hammer or striker turning on the fulcrum pin a' and B is the
spring by which the hammer or striker is operated; C is the sear turning about
the fuleram pin D and engaging at c with the notch a in the hammer or striker A
when the gun is cocked. is the tail end of the sear which is lifted by the
trigger blade E and releases the hammer or striker A when the trigger finger e
is pulled.
In carrying out this Invention we provide a safety lever F which is arranged
underneath the sear C. This safety lever l' is as shewn a short two armed lever
turning on a fulcrum pin f situated at a short distance behind the fulcrum pin D
of the sear C. The arm of this safety lever F is made as a tooth at 3 arranged
to engage in a notch which we form in the downwardly projecting part of the
sear situated preferably though not necessarily immediately under the fulcrum
pin 1) of the sear. The other arm f of the safety lever projects backwardly
and has a side projecting piece f which is situated alongside of the usual similar

page_text: sido projecting piece of the sear C so that both the sear C and the safety lover F
will be lifted by the trigger blade E when the trigger finger el is pulled. The
small spring g fixed on the side plate of the lock acts upon the shoulder
lever and brings the latter back to its normal position after it has been lifted
by the trigger blade.
of the
When the gun is cocked in full bent and the sear C is engaging with the usual
notch a in the tail piece of the hammer or striker A and maintaining the hammer
or striker in its cocked position as shewn in Figs. 1 and 6, the tooth or projec-
tion of the safety lever F engages in the said notch of the scar C and renders
it impossible for the sear C to be lifted without first lifting the tail end f³ of the safety
lever so as to turn the toothed end f3 of the safety lever I out of the notch c¹
of the sear. It is thus quite impossible for the sear C to jar off and release the
hammer or striker A unless the trigger el is pulled. When the trigger finger el
is pulled the trigger blade E first lifts the tail end f of the safety lever F very
slightly as in Fig. 2 so as to free the toothed end f³ of the locking lever F from
the notch in the sear C thus unlocking the sear C and allowing it to lift and
release the hammer or striker A as the pulling of the trigger el is continued.
It is to be understood that this Invention is applicable to all kinds of gun
locks for single barrel or double barrel guns and other small arms whether the
said gun locks are made with hammers or are such as are known as "hammerless,"
and that our Invention is applicable both to single trigger and to double trigger
guns.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is:-
1. In sporting guns and other small arms the employment with the sear, or
with each of the scars, of a safety lever arranged to engage with a notch in and
lock the rear when the gun is cocked to full bent and so that when the trigger is
pulled the safety lever will by the trigger blade be lifted and release the sear immedi-
ately lefore the sear is lifted to release the hammer or striker, substantially as
decribed.
2. In a sporting gun or other small arm the combination with the hammer
or striker or with each of the hammers or strikers of the sear C arranged to retain
the hammer or striker cocked at full bent and made with a notch at the back
part of the same, the safety lever Farranged to engage with the notch of the
sear and lock the same when the gun is cocked and made with a projecting tail
piece f³ adjacent to the tail of the sear, and the trigger and trigger blade adapted
to lift the tail end of the safety lever and release the same from the sear im-
mediately before the trigger blade lifts the sear and leases the hammer or
striker, all arranged and operating substantially as hereinbefore described with
reference to the accompanying drawings.
