IMPROVEMENTS IN BREECH-LOADING FIRE-ARMS
Year: 1865

page_text: LETTERS PATENT to Samuel Trulock, Richard Trulock, and William
Trulock, of 11, Essex Quay, Dublin, for the Invention of "IMPROVEMENTS
IN BREECH-LOADING FIRE-ARMS."
Sealed the 27th June 1865, and dated the 28th January 1865.
PROVISIONAL SPECIFICATION left by the said Samuel Trulock, Richard
Trulock, and William Trulock, at the Office of the Commissioners of
Patents, with their Petition, on the 28th January 1865.
We, SAMUEL TRULOCK, RICHARD TRULOCK, and WILLIAM TRULOCK, of
11, Essex Quay, Dublin, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN BREECH-LOADING FIRE-ARMS," to be as follows:-
This Invention consists in the application of two bolts to the ordinary
Lefauchaux breech-loading gun, one locking into a projecting piece of iron or
under grip at the under side of the barrel or barrels, the other locking into a
recess at the top of them. These bolts are actuated by a single external lever
which is attached to a cross pin carrying an internal double lever which works
into them, and a spring of sufficient strength acting on this double lever keeps
the bolts always pressed home or locked, unless when the external lever is
depressed, which motion unlocks the gun, and the barrel or barrels will then be
thrown up by their own weight. In locking the gun it is merely necessary to
close the barrel or barrels against the stock, which action pressing back the

page_text: top bolt also causes the bottom bolt to move forward, clearing the way for the
under grip, into which, and the top recess, the bolts shoot as soon as the barrel
or barrels are home. On the external lever, and at the far end of the cross
pin, cams or small projections are wrought, which raise the hammers to half-
cock simultaneously with unlocking the gun, and the position and form of the
external lever permits of the gun to be unlocked without removing the hand
from the trigger guard.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Samuel Trulock, Richard Trulock, and William Trulock, in
the Great Seal Patent Office on the 17th July 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, SAMUEL
TRULOCK, RICHARD TRULOCK, and WILLIAM TRULOCK, of 11, Essex Quay,
Dublin, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of January, in the year of our
Lord One thousand eight hundred and sixty-five, in the twenty-ninth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto us, the said Samuel Trulock, Richard Trulock, and William Trulock,
Her special licence that we, the said Samuel Trulock, Richard Trulock, and
William Trulock, our executors, administrators, and assigns, or such others
as we, the said Samuel Trulock, Richard Trulock, and William Trulock, our
executors, administrators, and assigns, should at any time agree with, and
no others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, 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 we, the said Samuel
Trulock, Richard Trulock, and William Trulock, our executors or adminis-
trators, by an instrument in writing under our, or their, or one of their
hands and scals, 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.

page_text: NOW KNOW YE, that we, the said Samuel Trulock, Richard Trulock,
and William Trulock, do hereby declare the nature of our said Invention, and
in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement and accompanying Drawings,
that is to say:-
This Invention consists in the application of two bolts to the ordinary
Lefaucheaux breech-loading gun, one locking into a projecting piece of iron
or under grip at the under side of the barrel or barrels, the other locking into
a recess at the top of them. These bolts are actuated by a single external
lever which is attached to a cross pin carrying an internal double lever
which works into them, and a spring of sufficient strength acting on this
double lever keeps the bolts always pressed home (or locked) unless when the
external lever is depressed, which motion unlocks the gun, and the barrel or
barrels will then be thrown up by their own weight. In locking the gun it is
merely necessary to close the barrel or barrels against the stock, which action
pressing back the top bolt also causes the bottom bolt to move forward,
clearing the way for the under grip, into which and the top recess the bolts
shoot as soon as the barrel or barrels are home. On the external lever, and
at the far end of the cross pin, cams or small projections are wrought, which
raise the hammers to half-cock simultaneously with unlocking the gun, and
the position and forin of the external lever permits of the gun being unlocked
without removing the hand from the trigger guard.
The above description will readily be understood, reference being made to
the accompanying Drawings, of which Fig. 1 represents a side elevation, and
Fig. 2 a longitudinal section of our improved breech-loading gun.
B and C are the two bolts shewn in Fig. 2, the bolt B locks into the
projecting piece of iron or under grip A which is attached to the under side
of the barrel or barrels G, and the bolt C locks into a recess at the top of
them. D is the external lever, attached to a cross pin I carrying the internal
double lever E, and working into the bolts B and C; on depressing this the
gun is unlocked, and the barrel or barrels are then thrown up by their own
weight, as shewn Fig. 2; simultaneously with unlocking the gun the hammers
are raised to half-cock by means of cams or projecting pieces J wrought on
the external lever D at the far end of the cross pin I, the position and form
of the lever permitting the gun to be unlocked without removing the hand
from the trigger guard; H is the spring acting on the double lever E, and
keeping the bolts B and C always pressed home unless unlocked by depressing
the external lever D. In locking the gun all that is necessary is to close the
barrel or barrels G against the stock, in doing which the bolt C is pressed

page_text: back, while the bolt B is driven forward by the action of the internal lever
working on the cross pin I, and clears the way for the under grip A, into
which the bolt shoots simultaneously with the bolt C shooting into the recess
above the barrels.
Having thus described our Invention, what we claim and desire to secure
by Letters Patent is, the peculiar arrangement of breech-loading rifle, as
herein-before described and shewn in the accompanying Drawings.
In witness whereof, we, the undersigned Samuel Trulock, Richard
Trulock, and William Trulock, have hereunto set our hands and seals,
this Sixth day of July, in the year of our Lord One thousand eight
hundred and sixty-five.
