PROVISIONAL SPECIFICATION left by the said Thomas Perkes at the
Office of the Commissioners of Patents, with his Petition, on the
20th July 1874.
I, THOMAS PERKES, of No. 4, Duck Lane, Wardour Street, Soho, in
the County of Middlesex, Manufacturer, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN BREECH-LOADING FIRE-ARMS,”
to be as follows:-
The object of the Invention is to obtain increased security in retaining
the breech pieces of fire-arms correctly in position during firing. This
object I effect by the use of double sliding bolts capable of readily
locking by three catch pieces forming a treble grip. These sliding
pieces or bolts as employed by me are capable of sliding in parts of the

page_text: breech piece and of locking into or on three recesses or parts of pro-
jections, or a "lump" or "lumps" from the under side of the barrel or
barrels. They are acted upon by a double ended lever, the axis of which
carries another lever arm by which the bolting is readily released when
required, whilst the bolts are otherwise retained in position for locking
by spring pressure constituting a snap action.
The method of operating for unlocking the double sliding bolts may
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Perkes in the Great Seal Patent Office on
the 19th January 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
PERKES, of No. 4, Duck Lane, Wardour Street, Soho, in the County of
Middlesex, Manufacturer.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of July, in the year of our
Lord One thousand eight hundred and seventy-four, in the thirty-eighth
year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Thomas Perkes, Her special licence that
I, the said Thomas Perkes, my executors, administrators, and assigns, or
such others as I, the said Thomas Perkes, my 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, excrcise, 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 Thomas
Perkes, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals; should particu-
larly 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 I, the said Thomas Perkes, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by
the following statement:-
:
The object of the Invention is to obtain increased security in retaining
the breech pieces of fire-arms correctly in position during firing. This.
object I effect by the use of double sliding bolts working in opposite.
directions and capable of readily locking by three catch pieces forming
a treble grip. These sliding pieces or bolts as employed by me are
capable of sliding in a slot or groove in the body of the action and of
locking into or on three recesses or projections in the lump or lumps.
attached to the under side of the barrel or barrels. They are acted upon
by a double ended lever, the axis of which carries another lever arm by
which the bolting is readily released when required, whilst the bolts are
otherwise retained in position for locking by spring pressure constituting
a snap action.
These improvements are illustrated in the accompanying Drawings, in-
which Fig. 1 is a longitudinal sectional view of the back end of a fire-
arm constructed according to the Invention. Fig. 2 a longitudinal side
elevation of the same, and of the breech and under side of the
fire-arm.
Fig. 3, a longitudinal plan or top view of the latters.
Fig. 4 and 5, longitudinal sectional views showing the bolts, lever, and
catches when catching or uncatching, and Fig. 6 bolt and lever detached
views.
Same letters indicate similar parts in these Figures.
A and B are the sliding bolts; C, the lever operating the same;
D, D', D", are the catch pieces, and E, E¹, E", the recesses into which
the latters lock; F is a lever working the lever C through a shaft or
pivot G.
In the Fig. 1 the sliding bolts A and B are shown as they lay in the
body of the action, with the double ended lever C attached thereto in
the recesses at the ends of the bolts.
In the Fig. 2 the steel lump on the under side of the barrels is
shown fitted into the action with the recesses E, E, E, into which the
catch pieces D, D, D, securely lock.

page_text: By pressing against the left-hand side of the lever F the shaft or
pivot G of which is attached to the lever C, causes the bolt B to move
backward at the same time that the bolt A moves forward, thus releasing
the barrel for reloading.
The method of operating for unlocking the double sliding bolts for
reloading may be varied, and the said bolts can be applied in whatever
shape or form, but I prefer to work them as shown in Drawings.
Having thus, desoribed my Invention, and in what manner the same
is to be performed, I would have it understood that I do not confine
myself to the precise details above enumerated, as they may obviously 1
be modified without departing from the Invention, but what I claim
and desire to secure by the said Royal Letters Patent is, in constructing
breech-loading fire-arms the double sliding bolts working in opposite
directions and capable of readily locking the breech pieces, substantially
as above described and represented in the accompanying Drawings.
In witness whereof, I, the said Thomas Perkes, have hereunto set my
hand and seal, the 19th day of January, in the year of our Lord
One thousand eight hundred and seventy-five.
