"at the Office of the Commissioners of Patents, with his Petition, on
the 5th April 1866.'
I, FRANK EMSDORFF WALKER, of Waterloo Road, in the County of Surrey,.
Gun Maker, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN BREECH-LOADING FIRE-ARMS," to be as follows:-
This Invention has, first, for its object improvements in the mechanisın
(commonly called the "extractor") employed for partially withdrawing the
exploded cartridge cases of breech-loading fire-arms: For this purpose I
arrange a stationary lever or arm so as to move in a curved recess formed in
the fore end of the stock of the gun. The upper end of this lever passes
through a slot formed between the barrels and passes into another slot in the
"extractor" rod, thereby preventing the extractor from being withdrawn
.if

page_text: while the gun is together, but affording the facility for removal, cleaning, or
repair by taking off the fore end of the stock, to which the lever before referred
to is connected. The lower end of the lever bears against the under part of
the body of the action of the gun, thus causing the upper arm to give motion
to the extractor when the breech of the gun is opened. My improvements
are applicable to all guns which open at the breech end by tilting the breech
end of the barrels.
The second part of my improvements consists in so placing the lock that
the axle of the tumbler is about in a line with the back of the action, and the
hammer is made in one piece, so that when down the nose will project slightly
through a slot cut in the back of the action, thereby striking the cap in the
centre of the cartridge, thus dispensing with the instrument or striker usually
employed for exploding central-fire breech-loading cartridges. A portion
of the lock is in this arrangement let into the action.
The third part of my Invention relates to improved modes of attaching the
"fore end" to the barrels. For this purpose, in one arrangement, instead of
the ordinary bolt I employ a round pin having a lever arm thereon. The
central part of this pin is partly eut away, the loop on the under side of the
barrels being formed with an opening which when the lever is moved forward
admits of the separation of the parts, but when the lever is moved backwards the
parts are secured together. By this means the parts may be readily separated
without the trouble of withdrawing a bolt by merely depressing the lever with
the thumb and reversing its position. Another mode of accomplishing this
object is by employing a similar pin and lever, the pin in this arrangement not
being cut away in the centre, the loop having a round hole for the pin to pass
through. On the side of the pin a portion of a screw thread is cut, into
which a fixed stud enters, and by moving the lever as before described the pin
will be forced outwards or withdrawn by the action of the fixed stud on the
screw thread, and the pin will be thus withdrawn from the loop to release or
separate the parts.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of April, in the year of our Lord One
thousand eight hundred and sixty-six, in the twenty-ninth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Frank Emsdorff Walker, Her special licence that I, the said Frank Emsdorff
Walker, my executors, administrators, and assigns, or such others as I, the said
Frank Emsdorff Walker, my executors, administrators, and assigns, should at
any time agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might maké, usė,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
BREECH-LOADING FIRE-ARMS," upon the condition (amongst others) that I, the
said Frank Emsdorff Walker, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same to be
filed in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Frank Emsdorff Walker, do hereby
declare the nature of the said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
This Invention bas, first, for its object improvements in the mechanism
(commonly called the "extractor") employed for partially withdrawing the
exploded cartridge cases of breech-loading fire-arms. For this purpose I
arrange a stationary detached lever or arm arranged so as to move in a curved
recess formed in the "fore end" of the stock of the gun by the act of opening
or closing. the breech end. The upper end of this lever passes through a slot
formed between the barrels, and passes into another slot in the "extractor"
rod, thereby preventing the "extractor" from being withdrawn while the gun
is together, but affording the facility for removal, cleaning, or repair by taking
off the "fore end" of the stock, to which the lever before referred to is
connected. The lower end of the lever or arm bears against the under part of
the body of the action of the gun, thus causing the upper end of the arm to
give motion to the extractor when the breech of the gun is opened. This part
of my improvements is applicable to all guns which open at the breech end by
tilting the breech end of the barrels.
The second part of my improvements consists in so placing the lock that
the axle of the tumbler is about in a line with the back of the action, and the

page_text: hammer is made in one piece in place of employing a separate striker, so that
when down the nose will project slightly through a slot cut in the back of the
action, thereby striking the cap in the centre of the cartridge, thus dispensing
with the instrument or striker usually employed for exploding central-fire
breech-loading cartridges. A portion of the lock plate is in this arrangement
let into the action.
The third part of my Invention relates to improved modes of attaching the
"fore end"
or stock to the barrels. For this purpose, in one arrangement,
instead of the ordinary bolt I employ a round pin having a lever arm thereon.
The central part of this pin is partly cut away, the loop on the under side of
the barrels being formed with an opening which when the lever is moved
forward admits of the separation of the parts, but when the lever is moved
backwards the parts are secured together. By this means the parts may be
readily separated without the trouble of withdrawing a bolt by merely depress-
ing the lever with the thumb and reversing its position. Another mode of
accomplishing this object is by employing a similar pin and lever, the pin in
this arrangement not being cut away in the centre, and the loop having a
round hole for the pin to pass through. On the side of the pin a portion of a
screw thread or spiral groove is cut, into which a fixed stud enters, and by
moving the lever as before described the pin will be forced outwards or with-
drawn by the action of the fixed stud on the screw thread or spiral groove,
and the pin will be thus withdrawn from the loop to release or separate the
parts.

And in order that my Invention may be most fully understood and readily
carried into practice I will proceed to describe the Drawing hereunto annexed.
DESCRIPTION OF THE DRAWING.
Figure 1.shows a side view of a double gun closed and in a position ready
for being fired; this gun is shown as being furnished with "back-work
locks" Eigure 2 shows a side view of another double gun the parts being
opened ready for receiving a cartridge; this gun is represented as being
furnished with "bar locks," in order to show that either arrangement of the
locks is applicable for being employed in combination with my improvements;
and although these guns are shown in combination with a "double-grip
action" my improvements are equally applicable to any other arrangement of
"fall-down action." The other Figures of the Drawing shew separate views
of some of the parts.; the same letters referring to corresponding parts in all
the Figures. A is the "extractor" arranged and actuated according to the
first part of my improvements; a is the extractor rod, a¹ being a slot through

page_text: which the arm 6 passes to cause the extractor to move to and fro, and also
preventing it from being withdrawn from the barrels while the fore end is on.
B is a lever or arm, the upper part 6 of which passes through the slot a¹ in
the extractor rod; this lever or arm B is placed in a curved recess c³ formed
in the face of the "fore end" C (or the part which connects the action to the
barrels when they are opened for the purpose of being reloaded); and c is a
stud or pin the point of which enters a slot c¹ in the lever or arm B, thereby
preventing it from falling out of the curved recess in the fore end C when it
is removed from the gun. In calling the lever or arm B stationary it should
be understood as meaning that the end b' is so formed (according to the action
to which it is fitted) as to bear against the body of the action, consequently
so far as its relative position with the body is concerned it is stationary ; but
by the action of opening the breech end of the barrels the fore end möves
round the arm or lever, and the end 6 passing along the slot between the
barrels moves the extractor rod outwards, thus extracting the cartridge. The
removal or detaching of the, "fore end" allows the extractor to be readily
withdrawn for cleaning or repairs.
ments.
!
I will now describe the mode of carrying out the second part of my improve-
D is the hammer attached in the usual manner to the lock; d is the
nose, which, owing to the axis of the tumbler being directly under it, is
enabled to pass through a slot or opening d formed in the back of the action
(as shewn by the dotted lines), by which arrangement the cap in the cartridge
receives a direct blow from the nose of the hammer without the intervention
of a striker as heretofore practised for exploding central-fire breech-loading
cartridges, great facility being also afforded for cleaning.
I will now describe the third part of my improvements. E, Figure 6, is a
round pin which I employ instead of an ordinary bolt to attach the fore ends
or the stocks to the barrels; e is a lever which when pressed to the stock falls
into a recess formed therein to secure the parts together; e is a cut made half
way through this pin, so that when the position of the lever e is reversed the
balf round portion of the pin E is placed in such a position as to pass reality
through an opening e', Figure 1, in the loop 3 on the barrels, in order to
separate the parts; but when the lever e is replaced the fore end or stock is
beld perfectly secure by the half round portion of the pin acting against the
projection on the loop to prevent the separation of the barrels from the fore
end or stock. Or, by means of another arrangement, a round pin F, Figure 7,
and a lever fis employed, a simple round hole being formed in the loop (f,
Figure 2). On the pin F a portion of a screw thread or spiral groove is
formed, into which a fixed stud f enters. As the lever is reversed or turned

page_text: over the action of the fixed stud f on the screw thread or spiral groove with-
draws the pin F sufficiently out of the loop e³ to allow the fore end or stock to
be removed. The pin F works in a small tube and plate fixed into the fore
end, as shown at G.
Having thus described the nature of my Invention, and the manner in which
the same is carried into practice, I would have it understood that I do not
confine myself to the exact details herein described, as the form and arrange-
ment of the parts may be considerably varied without departing from the true
character of my Invention; but what I claim is,-
First, the arrangement and combination of parts for actuating the cartridge
"extractor" A of breech-loading fire-arms by means of the lever or arm 6 or
its mechanical equivalent, as herein shown and described.
Secondly, I claim the so arranging of the locks of central-fire breech-loading
fire-arms that the hammer or cock will give a direct blow in order to explode
the cartridge, as herein shown and described, whereby the intervention of a
separate striker is dispensed with.
Lastly, I claim the arrangement and construction of the parts shown in
Figures: 1, 2, 6, 7, and 8, for attaching and securing the barrels to the "fore
end" or stock, as herein described, for the purpose of more readily attaching
and detaching the same.
In witness whereof, I, the said Frank Emsdorff Walker, have hereunto
set my hand and seal, this Fifth day of October, in the year of our
Lord One thousand eight hundred and sixty-six.
