TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JAMES

in the County of Middlesex, Fireproof Safe Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters

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
James Parrish, Charles Thatcher, and Thomas Glasscock, Her special licence
that we, the said James Parrish, Charles Thatcher, and Thomas Glasscock,
our executors, administrators, and assigns, or such others as we, the said
James Parrish, Charles Thatcher, and Thomas Glasscock, 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 "PREVENTING THE FORCING OR WEDGING OPEN IRON SAFES, IRON
DOORS, AND STRONG Rooms," upon the condition (amongst others) that we, the
said James Parrish, Charles Thatcher, and Thomas Glasscock, our executors
or administrators, by an instrument in writing under our, 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 we, the said James Parrish, Charles Thatcher,
and Thomas Glasscock, 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, reference being had to the
Drawing hereunto annexed, and to the letters and figures marked thereon,
(that is to say) :-
Our Invention for preventing the forcing or wedging open iron safes, iron
doors, and strong rooms, consists in forming the doors and door frames of safes
and strong rooms with dovetails round the edges of these parts. The dove-
tails are cut out of the solid metal, and by preference the dovetails on the door
should project and fit into corresponding dovetail sockets cut in the frame.
The door and also the frame is lined with sheet steel in order to prevent the

page_text: door from being drilled through for the purpose of introducing any forcing
instruments.
In the accompanying Drawing Fig. 1 represents an elevation of the improved
construction of safe with the door open. Fig. 2 is a sectional plan view of
the door and door frame. A, A, is the door on which is screwed, rivetted, or
otherwise fixed a plate of hardened steel which cannot be drilled through.
The door is provided with a number of projecting dovetails a, a, a, which fit
into corresponding dovetail sockets b, b, made in the door frame which is also
provided with hardened steel plates impervious to any drills. It will be seen
that owing to the dovetails the sides of the door frame can never be forced
out by wedges sufficiently to allow of a crowbar or lever being introduced to
force open the door.
Having thus described our Invention for preventing the forcing or
wedging open iron safes, iron doors, and strong rooms, and having ex-
plained the manner of carrying the same into effect, we claim as our Invention
constructing the doors and door frames of iron safes, and strong rooms with
dovetails in order to prevent them from being forced open by wedging as
herein set forth.
In witness whereof, we, the said James Parrish, Charles Thatcher,
and Thomas Glasscock, have hereunto set our hands and seals,
the Twentieth day of December, in the year of our Lord One thousand
eight hundred and sixty-five.
