PROVISIONAL SPECIFICATION.
Improvements in Cocking and Safety Mechanism for Hammerless
Breech Loading Small Arms.
I, EDWIN GEORGE ANSON, of Slaney Street, Birmingham, Gun Manufacturer,
do hereby declare the nature of this invention to be as follows:-
The first part of my invention relates to side lock hammerless guns or guns
having tumblers mounted on the trigger plate and is applicable to both single and
double guns.
I will describe my invention in connection with a double gun. In the lump slot
of the action and below the lump, having taken part of lump away to admit it, I fit
a cocking lift which is in the form of a lever the fulcrum of lift being say about
three sixteenths below and half an inch or thereabouts behind the centre of the joint
pin of the action. This cocking lift is operated on at the front end by the forepart
iron in the act of opening the gun and the lift passes the whole length of the action
in the lump slots and slot beyond provided for it, branching out T shape at the
end of the action to engage with the tumblers of both locks thus cocking both locks
with one limb or lever on opening the gun.
In single guns the said cocking lift is arranged similarly as above described but
is either made straight to meet the work of the lock arranged in centre of trigger
plate, or is made with one extending arm only to engage with the tumbler of side
lock.
The second part of my invention relates to an auxiliary safety for hammerless
breech loading small arms applied as I will now describe. I retain the ordinary
automatic top slide, that is the push bar operated by the lever mechanism on
opening the gun and acting on an ordinary safety slide on the top of the gun and to
these my safety is applied and is arranged as follows:-My said safety consists of
a two armed lever working on a cross pivot in the strap of the action behind the
said automatic top slide. The end of one arm of this safety lever engages with
the triggers and effectually locks them and the end of the other arm protrudes
through the strap of the action and extends backwards. This safety lever is held
on the triggers by a spring and is released when in the act of firing the gun is
grasped by the hand pressing on the protruding end of the safety lever. The said
safety lever is also locked by the said top automatic slide every time the gun is
opened, the said slide being formed so as to jam itself between the strap of the
action and the said safety lever thus ensuring the triggers being securely locked.
The gun to which my safety is applied as above described cannot be fired when the
ordinary safety slide is moved as the gun is still safe until the protruding end of
the safety lever is pressed down in the act of grasping the gun for firing. When the
pressure on the safety lever is removed the safety lever immediately re-engages the
triggers thus the triggers are always locked (until the gun is grasped for firing)
whether the automatic slide safety is on or not.

Improvements in Cocking and Safety Mechanism for Hammerless
Breech. Loading Small Arms.
I, EDWIN GEORGE ANSON, of Slaney Street, 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:-
The first part of my invention relates to side lock hammerless guns or guns
having tumblers mounted on the trigger plate and is applicable to both single, and
double guns, and consists in the hereindescribed improved means by which the gun
is cocked by the act of opening the same.
1 will describe this part of my invention by referring to Figs. 1, 2, 3 and 4 of the
accompanying drawings of which
Fig. 1 represents in part sectional elevation as much of a double barrel gun open
as is recessary to illustrate my invention;
Fig. 2 shews the same parts as Fig. 1 but representing the gun as closed;
Fig. 3 represents in elevation and in plan the lever cocking lift which according
to this invention I employ to act upon the tumblers and cock the gun by the act of
opening the same and
Fig. 4 represents in plan a modified form of the said lever cocking lift and the
two tumblers.
The same letters of reference indicate the same or corresponding parts. in
Figures 1, 2, 3 and 4.
In carrying out this part of my invention I proceed as follows:-In the lump
slot a of the action and below the lump b I fit the cocking lift C the lower part of
the lump having been taken away as shewn to admit the cocking lift C. This
cocking lift C, as will be seen by an examination of my drawing, is in the form of
a two armed lever the fulcrum c¹ of the same being say about three sixteenths of
an inch below the centre of the joint pin d of the action and about half an inch
or thereabouts behind the centre of the said joint pin; but it is to be understood
that I do not confine myself to this particular position of the fulcrum.c. The
cocking lift C is operated on at the front end c² by the forepart iron e as shewn in
Fig. 1 by the act of turning down the barrels in opening the gun, and the cocking
lift C passes the whole length of the action in the lump slots a and through the
slot which I provide for it, the back end of the cocking lift C branching out
Tshaped by having the extending side arms ce so as to engage with the tumblers g
of both locks thus cocking both locks with the one limb or lever C upon opening.
the gun as shewn in Fig. 1. The act of closing the gun as shewn in Fig. 2 causes
the lump b to act upon the cocking lift C and move the latter down to the position
shewn by Fig. 2 when it fills up the lump slot a.
Instead of the cocking lift being made T shaped with the extending arms cc
as above described to engage with the tumblers g, I may obtain the same result by
making each of the tumblers g with a branching arm g' as shewn in Fig. 4 with
which the cocking lift C will engage underneath and then in this case the
extending arms cc of the cocking lift C shewn in Fig. 3 may be dispensed with as
in Fig. 4.
=
In single guns the said cocking lift or lever C is arranged similarly as above
described and is either made straight as shewn in Fig. 4 to meet the work of the
lock arranged in the centre of the trigger plate or the lever C is made with only
one extending arm or c to engage with the tumbler of the side lock.
The second part of my invention relates to an auxiliary safety for hammerless
breech loading small arms applied as I will now describe by referring to Figs. 5, 6, 7

page_text: and 8 of which Figs. 5 and 6 shew in sectional side elevation so much of a
double barrel gun as is necessary to illustrate this part of my invention. Figs. 7
and 8 illustrate a modified form of this part of my invention in which the safety lever
which I employ is arranged to project through the underside of the gun instead of
through the top of the same as in Figs. 5 and 6.
I retain the ordinary automatic top slide that is the push bar i which is operated
by the lever mechanism on opening the gun and acts on the ordinary safety slide j
on the top of the gun and to these my auxiliary safety is applied and is arranged as
follows Keferring firstly more particularly to Figs. 5 and 6 my said auxiliary
safety consists of the two armed lever K working on the cross pivot in the
strap m of the action behind the ordinary automatic top slide j. The end of one
arm k¹ of the safety lever K engages with the triggers n² n³ as shewn and effectually
locks them and the other arm k protrudes through the strap m of the action and
extends backwards as shewn, a small recess o being cut in the stock of the gun to
admit the arm . This safety lever K is held on the triggers as shewn by a spring.
such as the coiled spring parranged in a hole in the gun stock under the arm k³.
The safety lever K is itself also locked by the automatic top slide; every time
the gun is opened the said slide; being formed with a shoulder j¹ so as to be
jammed by the push bar i between the strap m of the action and a step k³ formed
on the safety lever K thus ensuring the triggers being securely locked. g is the
ordinary small cross pin which passes through the downwardly projecting part of the
automatic top slide ; and engages under the strap m to prevent the top slide j
rising. When the ordinary automatic safety slide is pushed forward before firing
as shewn in Fig. 6 the gun is still safe until the protruding end of the safety
lever K is pressed down in the act of grasping the gun for firing which has the
effect of raising the arm k¹ off the triggers n' n³ (as shewn by the dotted lines in
Fig. 6) leaving the triggers free to be pulled. When the pressure on the arm k³ of
the safety lever is removed the safety lever K immediately re-engages the triggers
thus the triggers are always locked (until the gun is grasped for firing) whether the
automatic safety slide j is pushed back to lock the triggers or not. Thus when one
barrel has been fired the trigger of the other barrel will be locked by the auxiliary
safety lever K.
In the arrangement of this part of my invention shewn by Figs. 7 and 8 the
auxiliary safety lever K is jointed at / to the strap m of the action but is made a
one armed lever projecting through the stock of the gun underneath so as to be
pressed into the stock by the act of grasping the gun for firing which has the effect
of lifting the step of the lever K off the triggers n' n leaving them free to be
pulled. When the gun is opened and the automatic top slide j is pushed back by
the push bar the downwardly projecting part j' of the automatic top slide is
jammed between the step of the lever K and the strap m of the action so as to
lock the auxiliary safety lever K and the triggers n' n until the automatic top
slide is pushed forward as shewn in Fig. 8 to release the auxiliary safety lever K,
j
when the gun can be fired by first grasping the same so as to move the auxiliary
safety lever K into the stock and release the triggers n¹ n' as above described.
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 hammerless breech loading small arm and in combination with the fore-
part iron and tumbler or tumblers thereof, the employment of the lever cocking
lift C arranged in the lump slot of the action so as to be acted upon at one end by
the fore part iron when the gun is opened and at the other end act upon and cock
the tumbler or tumblers, substantially as herein before set forth and illustrated by
Figs. 1, 2, 3 and 4 of the accompanying drawings.
2. In a hammerless breech loading small arm and in combination with the top
safety slide and push bar and the trigger or triggers of the gun, the employment

page_text: of the auxiliary safety lever K constructed and arranged to operate substantially
as hereinbefore described and illustrated by Figs. 5 and 6 and by Figs. 7 and 8 of
the accompanying drawings.
