page_text: LETTERS PATENT to William George White, of New Malden, in the
County of Surrey, Engineer, for the Invention of "IMPROVEMENTS
IN THE MANUFACTURE OF STEEL SAFES AND STRONG ROOM DOORS, AND IN THE
MODE OF FASTENING THEM, PARTS OF WHICH IMPROVEMENTS ARE APPLICABLE TO
TRAK SARG "
PROVISIONAL SPECIFICATION left by the said William George White
at the Office of the Commissioners of Patents, with his Petition,
on the 25th October 1875.
•
I, WILLIAM GEORGE WHITE, of New Malden, in the County of
Surrey, Engineer, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE MANUFACTURE OF STEEL SAFES AND STRONG ROOM
DOORS, AND IN THE MODE OF FASTENING THEM, PARTS OP WHICH IMPROVEMENTS ARE
APPLICABLE TO IBON SAFES," to be as follows:-

page_text: steel. On the inner sides of the shell or body I cast projections. The
shell thus cast is then annealed so as to make it soft and tough.
Secondly. I cast plates of crucible cast steel corresponding with the
sides in size, having indentations corresponding with the projections in
the outer shell or body. These plates I do not anneal, consequently
they are very hard, and being fitted to the soft shell in the manner
described, prevents drilling.
Thirdly. In making the door I use three plates. I cast the first or
front plate with projections in the manner above described; the third or
back plate I also cast with projections on one side; on the other or inner
side I cast the lock case or chamber to contain the bolts or fasteners.
These two plates I anneal, the second or middle plate I cast with
corresponding projections on each side and screw or otherwise fasten to
the front and back plates. This plate I do not anneal.
In order that the door may be securely fastened I employ a series of 1
bolts or fasteners of various shapes on all sides or edges of the door,
which bolts are screwed or rivetted to moving sliding bars inside the
lock chamber. These bars have slots in two or more places. In each
slot is a stud or pin fixed to the door. Levers are attached to these
sliding bars, and each lever connected to a rotating disc. Attached to:
the rotating disc is a spindle, to which motion can be given by moving
or turning a handle, and by this means the disc can be made to revolve,
thereby actuating the levers, causing the bars to slide and drawn towards
the centre of the lock case or chamber. By this means the bolts are
caused to slide into corresponding receptacles attached to the side or
frame of the safe. The bolts being thus slid into the receptacles by
further turning the handle, a second motion is given to the sliding bolts,
by means of which projections on the bolts and receivers are slid into
slots corresponding. The whole are secured by a lock of any approved
construction.
In order that the various shaped bolts may be better understood, I
have shown on the accompanying Drawing four different shapes.
Fig. 1 shows a double-headed bolt with projections and slots.
Fig. 2 shows holder with projections and slots.
Fig. 3 shows Figs. 1 and 2 drawn in locking position.
Fig. 4 shows bol without projections, but with slots.
Fig. 5 shows holder with projections without slots.

page_text: Fig. 6 shows a single-headed bolt with two slots. A is the moveable
bolt, which by the first action was brought into position, the slots in it
being brought into position opposite the projections B, B. By the
second motion it is caused to embrace them as shown.

bolt, which by the first action was brought into position, the slots in it
being brought into position opposite the projections B, B. By the
second motion it is caused to embrace them as shown.

Patent, and of an Order of the Lord Chancellor, by the said
William George White in the Great Seal Patent Office on the 12th
May 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
GEORGE WHITE, Engineer, of New Malden, in the County of Surrey,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-fifth day of October, in the
year of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said William George White, Her
special license that I, the said William George White, my executors,
administrators, and assigns, or such others as I, the said William
George White, 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, exercise, and vend, within the United Kingdom
of Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "IMPROVEMENTS IN STEEL SAFES AND STRONG ROOM DOORS,
PARTS OF WHICH IMPROVEMENTS ARE APPLICABLE TO IRON SAFES," upon the con-
dition (amongst others) that I, the said William George White, my
executors or administrators, by an instrument in writing under my, 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, on or before the Twelfth day of May One thousand
eight hundred and seventy-six.

page_text: NOW KNOW YE, that I, the said William George White, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say :.
My improvements consist,—
First. Of casting the outer shell or body of the safe of crucible cast
steel. On the inner sides of the shell I cast projections of various
shapes. The shell thus cast is then annealed so as to make it soft and
tough.
Secondly. I cast plates of crucible cast steel, having indentations
corresponding with the projections in the outer shell. The plates I do
not anneal, consequently they are very hard, and being fitted to the soft
shell by means of screws or rivet, prevents drilling.
Thirdly. I form the door of three plates. The front or outer plate I
cast with projections on one side. The third or back plate I also cast
with projections on one side. On the other or inner side I cast the lock
case or chamber to contain the bolts or fasteners. These two plates I
anncal. Between these two plates I screw or otherwise fasten a plate
corresponding on either side with the projections on the front and back
plates. This plate I do not anneal.
In order that the door may be securely fastened to the body of the
safe when locked I employ a series of bolts or fasteners of various
shapes on all sides or edges of the door or lock chamber. These bolts
or fasteners are screwed or otherwise fastened to moving sliding bars
inside the lock case or chamber. These bars have slots in two or more 2
places, and in each slot is fixed a stud or pin. Levers are attached to
the sliding bars and connected to a rotating disc. Attached to this disc
is a spindle, to which motion can be given by moving or turning a
handle on the outside of the door. By this means the disc can be made
to revolve, thereby actuating the levers and causing the bars to slide and
be drawn towards the centre of the lock case or chamber. By so doing
the bolts are caused to slide into corresponding receptacles attached to
the side or frame of the safe. The bolts being thus slid into the
receptacles by further turning the handle a second motion is given to
the sliding bolts, by means of which projections on the bolts and holders 8
are drawn into slots or spaces, so interlocking each other. The whole of

page_text: these bolts being then secured by a small lock of any approved con-
struction, throwing a bolt into a slot in the revolving disc.
In order that the construction of the body of the safe and locking
apparatus may be better understood I will now proceed to describe the
accompanying Drawings.

page_text: Having now particularly described the nature of my said Invention,
and the manner in which the same is to be performed, I claim the
different shaped bolts and holders, as described.
I also claim the mode of working or fastening them in the manner
described.
I also claim the constructing the shells or bodies of safes, and in
the inner plates thereof in the manner herein-before described.
In witness whereof, I, the said William George White, have here-
unto set my hand and seal, this Twelfth day of May, in the
year of our Lord One thousand eight hundred and seventy-
six.
