PROVISIONAL SPECIFICATION.
Improvements in Fire and Thief Resisting Safes.
I, WILLIAM EDMUND BRAIN, of 33 Nursery Road, Harborne, in the City of
Birmingham, Safe Fitter, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in the construction of fire and thief
resisting safes, which are generally produced in sheet metal
"
In making a safe in the ordinary way, a frame is first built up, generally of
angle on, and to this fiame, the plates which form the sides of the body of the
safe, are attached by rivetting. In these my improvements, I dispense with the
aforesaid frame, and fiom one piece produce four sides of the body in the following
manuel —
I take a piece of sheet metal, a few inches wider than the desned width of the
safe, and of a length equal to the top, bottom and two sides. On the longest sides
of this plate, and at distances, corresponding to the width of the top, two sides and
bottom of safe, I cut away a portion, so that when it is bent as hereinafter
described, a close fitting mitre joint will be formed at the corners of the safe.
Also such corners can be produced more or less rounded according to taste. Such.
portions are cut away somewhat as follows:-I cut away a V-shaped portion and
at the apex of this I cut a horizontal slit extending a short distance on each side
and opening slightly towards the centre.
The plate is now bent so as to form the four sides of the body, the two ends
preferably meeting at the bottom of the safe, so as to form a butt joint, and may
be secured together by rivetting thereto on the inside a strip of metal
The plate is now further bent inwards at right angles along its edges so as to
form at the front, a frame into which the door may be fitted in the usual way, also
the edges of the plate at the bach are similaily bent inwards at night angles aud a
plate is fitted in to form the back of the safe, and may be secured in position by
rivetting strips of metal, on the inside to the said plate and the body of the safe.
If desired, the lining of a safe may be produced in the same way.

Improvements in Fire and Thief Resisting Safes.
ANI, WILLIAM EDMUND BRAIN, of 33 Nursery Road, Harborne, in the City of
Bumingham, Safe Futer, do hereby declare the nature of this invention and in
what mauuci the same is to be performed, to be particularly described and ascer-
tained and by the following statement :-
This invention relates to improvements in the construction of fire and thief
resisting sales, or trunks, and in order to explain more clearly my invention, I
have appended hereunto an illustrative drawing upon which are figures and
numbers of reference.

page_text: Fig. 1, a view of a sheet of metal as cut to form the rectangular shell such as
that of a safe.
Fig. 2, is a sectional view on line A-B Fig. 1, showing the longitudinal edges
bent on rounded at right angles to the main part of the plate.
Fig. 3, shows the plate bent at right angles at four points so as to form the
general shell or body.
Fig. 4, is a sectional plan view on line C-D Fig. 3, showing the method of
securing the joint in the body plate, and also the attachment of back plate and
bingo for door &c.
In making a safe in the ordinary way, a frame is first built up, generally of
angle iron, and to this frame, the plates which form the sides of the body of the
safe, are attached by vetting. In these my improvements, I dispense with the
afoi canid fiame, and from one piece produce four sides of the body in the following
manner
I take a piece of sheet metal 6, a few inches wider than the desired width of the
safe, and of a length equal to the top, bottoin, and two sides. On the longest sides
of this plate, and at distances 7, 7; 8, 8; 9, 9; 10, 10, corresponding to the
width of the top, two sides and bottom of safe, I cut away a portion, so that when
it is bent as shown in Fig. 3, a close fitting mitre joint as seen at 11, 12, 13 & 14,
will be formed at the corners of the safe Also such coiners can be produced
more or less rounded according to taste. Preferably this is done by bending the
plate 6, into the transverse sectional shape as seen in Fig. 2, before it is further
beut into the body shape as seen in Fig. 3, but if desired it may be bent after the
body has been formed.
Reverting to the parts at 7, 7, 8, 8º, 9, 9º, & 10, 10%, I cut away a V-shaped
portion and at the apex of this I cut a horizontal slit 15, extending a short
distance on each side and opening slightly towards the centre.
The plate is now bent so as to form the four sides of the body, the two ends
16 & 17, preferably meeting at the bottom of the safe, so as to form a butt joint,
and may be secured together by ivetting thereto on the inside n strip of metal 18.
Thus at the front the edges 19, 20, 21 & 22, form a fiame into which the door may
be fitted in the usual way, the hinge joint pieces such as 23, being rivetted thereto
18 seen in Fig 4, also the simular edges of the plate at the back being similail,
bent inwards at night angles, a plate 24, 18 fitted in to form the back of the safe,
and may be secured in position by vetting strips of metal 25, on the inside to the
said plate and the body of the safe.
If desued the lining of a safe may be produced in the same way.
Having now particularly descubed and ascertained the nature of this my sail
invention, and in what manner the same is to be performed, I declare that what!
claim is.
1. Forming the frames or bodies or limings of safes, trunks, or such like bodies,
by meaus of a plate 6, having the cut away parts at 7, 7, 8, 8, 9, 9, 10, 10, and
the slits at 15, all substantially as set forth and shown
2. The combination in a sale or hunk body on log of the plate 6, cut, shaped
and bent as described and shown, with a flush plate 24, secured thereto, for tle
back, all as described and shown upon the drawings.
3. In a enfe or other similar structure, the gencial combination and arrangement
of parts substantially as herein described and illustrated upon the drawings.
