page_text: LETTERS PATENT to George Hindshaw, of Manchester, in the County of
Lancaster, Plumber, for the Invention of "CERTAIN IMPROVEMENTS IN THE
CONSTRUCTION OF SAFES AND OTHER SIMILAR DEPOSITORIES."
CONSTRUCTION OF SAFES AND OTHER SIMILAR DEPOSITORIES."
PROVISIONAL SPECIFICATION left by the said George Hindshaw at the
Office of the Commissioners of Patents, with his Petition, on the 31st
March 1866.
I, GEORGE HINDSHAW, of Manchester, in the County of Lancaster, Plumber,
do hereby declare the nature of the said Invention for "CERTAIN IMPROVEMENTS
IN THE CONSTRUCTION OF SAPES AND OTHER SIMILAR DEPOSITORIES," to be as
follows:-
My Invention is designed for the purpose of preventing the use and
introduction of wedges or levers between the doors and sides of safes and
other depositories which are employed to force them apart, and is also de-igned
for the protection of the hinges of the doors of safes.
The improvements consist, first, in forming the edges of the metal plate
or door in the shape of a series of short undulations, or "O Gee" or convex
and concave curves, and in forming the sides of a corresponding shape, so that
one shall fit into the other when the door is closed, and as the joints round
the safe then present a series of short curves a flat-sided wedge of suflicient

page_text: width to exert force cannot be inserted. The hinges of the door are mounted
upon and attached inside the safe to the ends of bars which slide in bearings,
so that by first drawing out the door, which moves readily with the parallel
sliding bars to clear the thickness of the sides, the door may be opened, and
when closed and pushed into its place again the hinges are enclosed in the safe
and cannot be injured by violence.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Hindshaw in the Great Seal Patent Office on the
27th September 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HINDSHAW, of Manchester, in the County of Lancaster, Plumber, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirty-first day of March, in the year of our Lord
One thousand eight hundred and sixty-six, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said George Hindshaw, Her special license that I, the said George Hindshaw,
my executors, administrators, and assigns, or such others as I, the said Georgo
Hindshaw, 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 "CERTAIN IMPROVEMENTS IN
THE CONSTRUCTION OF SAFES AND OTHER SIMILAR DEPOSITORIES," upon the condition
(amongst others) that I, the said George Hindshaw, my executors or adminis-
trators, 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 within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said George Hind-haw, 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
and accompanying Drawings (that is to say):-
My Invention is designed for the purpose of preventing the use and intro-
duction of wedges or levers between the doors and sides of safes and other

page_text: depositories which are employed to force them apart, and is also designed for
the protection of the hinges of the doors of safes.
The improvements consist, first, in forming the edges of the metal plates or
doors in the shape of a series of short undulations, or "O Geo" or convex and
concave curves, and in forming the sides of a corresponding shape, so that one
shall fit into the other when the door is closed, and as the joints round the
safe then present a series of short curves a flat-sided wedge of sufficient
width to exert force cannot be inserted. The hinges of the door are mounted
upon and attached inside the safe to the ends of bars which slide in bearings,
so that by first drawing out the door, which moves readily with the parallel
sliding bars to clear thickness of the sides, the door may be opened, and
when closed and pushed into its place again the hinges are enclosed in the
safe and cannot be injured by violence.
In order that the Invention may be better understood and explained in
detail I have hereunto attached a Sheet of Drawings made upon a scalo of
about two inches to the foot.
Fig. 1 represents a tranverse vertical section of a safe having one of the
inner side plates displaced in to expose and shew the arrangement of rollers
and slido plates to which the hinges are secured, and also the slides with which
the rollers move.
Fig. 2 represents a front elevation of the safe and safe doors, and shews the
peculiar formation and construction of the undulating curved edges of the doors
forming a close and perfect joint with the safe when the doors are closed, as
shewn; and Fig. 3 represents a side elevation of the safe, shewing the position
of one of the doors when withdrawn from the safe preparatory to its being
swung back upon its hinges.
In Figs. 1, 2, and 3, a, a, is the body of the safe, to the inner sides of which
the parallel bars b, b, are secured; within these bars the slide plates c, c, are
supported by means of the rollers or bowls d, d; to the outer extremity of
these slide plates the doors e, e, are hung by the hinges f, f, so that when the
doors are closed the hinges are contained within the safe, but when it is
required to open the safe doors, whether their edges are undulating as shewn or
straight, the doors and hinges will require to be drawn out from the safe, as
shewn in Fig. 8, before being thrown back.
Having now described the nature of the said Invention, together with the
method of carrying the same into practical effect, I wish it to be distinctly
understood that I claim,-
First, the novel construction of safes or depositories whereby the hinges are
enclosed within the safe when shut.

page_text: And, secondly, the use and application of curved undulating or wave-like
surfaces to all or any of the edges of the plates which close the opening
to the safe, ns herein-before described, set forth, and fully illustrated in the
Drawings attacheil.
In witness whereof, I, the said George Hindshaw, have hereunto set my
band and seal, this Twenty-sixth day of September, in the year of our
Lord One thousand eight hundred and sixty-six.
