Sealed the 3rd September 1872, and dated the 13th July 1872.
COMPLETE SPECIFICATION filed by the said Robert Jones at the
Office of the Commissioners of Patents, with his Petition and
Declaration, on the 13th July 1872, pursuant to the 9th Section of
the Patent Law Amendment Act, 1852.

TO ALL TO WHOM THESE PRESENTS SHALL COME, BE IT KNOWN,
I, ROBERT JONES, of Liverpool, in the County of Lancaster, Gun Manu-
facturer, am in possession of an Invention for "IMPROVEMENTS IN CENTRAL-
FIRE BREECH-LOADING SPORTING GUNS," of which I believe I am the first and
true Inventor, and I, the said Robert Jones, having petitioned Her most
Excellent Majesty to grant unto me, my executors, administrators, and
assigns, Her Letters Patent for the said Invention, do hereby declare
the following written statement to be a full and complete description of
the said Invention, and the best means I am acquainted with for carry-

page_text: ing the same into practical effect, reference being had to the annexed
Drawings, and the letters and figures marked thereon (that is to
say) :—
.
The object of this Invention is improvements in central-fire breech-
loading sporting guns, whereby the barrel is more effectually secured to
the stock, and the striker withdrawn on the unbolting of the barrel for
the purpose of deflecting to receive the charge, and consists in the
peculiar construction, shape, and arrangement of the locking bolt which
secures the barrel or barrels in position when the gun is closed, and its
action on and connection with the striker or strikers being so con-
structed and arranged that it forces or draws back the striker or strikers
when opening or closing the gun, which completely and most effectually
prevents accidental discharge of the cartridge or cartridges by reason of
the strikers coming into contact therewith when opening or closing the
gun. The strikers work free and are without springs. The locking
bolt is worked by a lever having its fulcrum below the bolt, the lower
end of which lever may be in front of the trigger guard, or on the side
of the lock plate, or other convenient position.

On reference to the accompanying Drawings the general arrangement
and construction of my improved gun will at once be seen.
Figure 1 represents so much of the stock and barrel of a gun as will
be necessary to illustrate my improvements (shown in section).
A, stock of gun; B, barrel, (which is pivoted to the stock at c),
formed with D, D¹, and D², three lumps or tongue pieces having the
lower edge of the inner face bevelled off, above which there are trans-
verse grooves cut entirely across their inner faces to receive the trans-
verse bars of E, the bolt, which is seen detached in Figure 2. F and F,
vertical arms on the rear of the sliding locking bolt E, which carry
back G, the strikers. H, a spring, at the back of the bolt E for forcing
it forward when the same is not operated upon by K, a lever which
has its fulcrum at l.
Figure 2 is an elevation of the sliding bolt and one of the strikers
seen detached, and Figure 3 is a view of one of the strikers shown dis-
connected, and Figure 4 is an external elevation of a portion of a gun
stock, barrel, and lock seen closed, in which is seen M, a pin, the inner
end of which enters a slot for guiding and keeping the strikers in
position.

page_text: In operating this my improved gun I place it at half cock, then press
the lever K forward, which throws back the bolt E, thus releasing the
barrel so that the point is deflected and the rear elevated, and the
strikers G are carried back at the same operation. After inserting the
cartridge return the barrel to its former position, then by placing the gun
on full cock it is ready for discharging.
Having now fully described and ascertained the nature of this my
said Invention, I wish it to be understood that I do not confine myself
to the precise relative detail proportions or dimensions of the several
parts, as it will be readily seen the same may be considerably varied
without departing from the Invention, but what I claim as new and my
Invention is,―
First. The peculiar form and construction of the sliding locking
bolt marked E, arranged and operated as herein-before described and
set forth.
Secondly. The peculiar form, construction, and arrangement of the
strikers G, with their securing pins M, operated substantially in the
manner and for the purposes herein-before described and set forth.
And lastly, the general arrangements and combination of the several
parts marked D, D², D², E, F, G, H, and K, arranged and operated sub-
stantially in the manner and for the purposes herein-before described
and set forth.
In witness whereof, I, the said Robert Jones, have hereunto set
my hand and affixed my scal, this Twelveth day of July, in the
year of our Lord One thousand eight hundred and seventy-two.

of 44, Castle Street,
