page_text: LETTERS PATENT to John Bracher, of No. 11, Cannon Street West, in
the City of London, Iron Safe Manufacturer, for the Invention of
"IMPROVEMENTS IN IRON SAPES, STRONG ROOMS, AND DOORS."
Sealed the 18th September 1866, and dated the 27th March 1866.
PROVISIONAL SPECIFICATION left by the said John Bracher at the Office
of the Commissioners of Patents, with his Petition, on the 27th March
1866.
I, JOHN BRACHER, of No. 11, Cannon Street West, in the City of London,
Iron Safe Manufacturer, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN IRON SAPES, STRONG ROOMS, AND DOORS," to be as
follows:-
The object chiefly in view is to make fire-proof and other iron safes thief-
proof without materially increasing the weight, and for this purpose I proceed
thus: First, with respect to safes and strong rooms having single doors, I
make the door frame of T-iron of the section marked 1a in the Drawing
hereunto annexed, placed with the flange in the front of the safe, and there-
unto I affix by screws or rivetts on the inner side of the T-iron immediately
under the flange, in the position shewn in the Drawing, a locking bar, or bar
to receive the lock bolts of the door, rolled to the section marked 1 b, and I
make the piece which usually forms the door style of safes as now constructed

page_text: and the rim of the lock case in one piece, forming a T-iron of the section
marked 3 a in the Drawing; this I fix with the flange in front of the door
plate in the position shewn in the Drawing; these pieces will be reversed for
the hinge side of the door, as shewn at 2a, 2b, and 4 a.
I also attain my object in another way, as follows:-I make the front or
locking side of the door frame of iron, rolled to the section marked 1 in the
Drawing hereto annexed; the side of the frame to which the binges are
attached of iron rolled to the section marked 2 in the same Drawing; and I
make the top and bottom of the door frame of iron rolled to the section
marked 5. I make the door style and the sides or rim of the lock case in
one piece of iron rolled to the sections marked 3 and 4 in the same Drawing;
3 is the locking side of the door, and 4 the hinge side of the door. I mount
the door on a hinge, of which the point marked A is the centre, so that when
the door is closed the different sections of iron fit or dovetail one into the
other in such a manner that no wedge or other instrument can be driven
into the edges of meeting between the door and the sides of the frame of
the safe. As to safes or rooms with double doors, I make both sides of
the door frame of the pattern No. 2, as used for hinge side of a single door
safe, and the top and bottom of the pattern No. 5, and I make the door style
and rim of the lock case of the locking door, or door which closes last, of one
piece of iron rolled to the pattern marked No. 6. The above patterns may
be of any dimensions or thickness that the work in hand may require. The
door plate may be mounted either outside or inside any of the above patterns
9, 4, and 6; I prefer to mount it inside for obvious reasons.
My improvement in the angles of safes consists in using for the same
angle iron rolled in the shape No. 7, or, which would be cheaper, rolled in the
shapes and fastened together in the manner shewn at No. 8.
By the above means iron fire-proof safes, strong rooms, and doors may be
manufactured without any great increase of cost, and rendered proof against
force without diminishing the interior dimensions of the safes, without
injuring their fire-proof quality, and without materially increasing the
weight.
