Improvements in the Manufacture of Safes.
I, HARRY WITHERS CHUBB, of 128 Queen Victoria Street, in the City of
London, Lock and Safe Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in the method or means of manufacturing
certain of the parts of metallic safes. Heretofore it has been customary to make
the various parts of a steel or iron safe such as the body, lining, front frame,
lining front, lock and bolt case frame, and the proofing pans by connecting
together, by rivetting, screwing, or otherwise, pieces of metal of various sections
according to the nature and shape of the part to be produced, this method is
costly and the parts produced are not so strong as they would be if each were
made in one piece, seeing however that the metal must in most cases be wrought or
malleable it has been very difficult and expensive to make each part in one piece
by welding. The object of my present invention is to provide means for making
each of the various parts of one piece of metal without rivetting, screwing, or
welding, several pieces together. For this purpose I stamp or press each part out
of a single sheet or plate of metal of suitable thickness and size in properly
formed moulds, or dies by any known stamping or pressing machinery, preferably,
in most cases, while the sheet or plate of metal is in a red-hot condition. These
parts are formed in the stamping or pressing process with suitable flanges or other
projections or parts whereby they can be screwed or rivetted together or to other
parts so as to form the finished safe, which when so made is much stronger and
more satisfactory in many ways than a safe the principal component parts of
which are made up of several comparatively small pieces screwed or rivetted
together.

Improvements in the Manufacture of Sares.
I, HARRY WITHERS CHUBB, of 128 Queen Victoria Street, in the City of
London, Lock and Safe Engineer, do hereby declare the nature of this invention,
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention relates to improvements in the method or means of manufacturing
certain of the parts of metallic safes. Heretofore it has been customary to make
the various parts of a steel or iron safe such as the body, lining, front frame,

page_text: lining front; lock and bolt case frame, and the proofing pans by connecting
together, by rivetting, screwing, or otherwise, pieces of metal of various sections
according to the nature and shape of the part to be produced. This method is
costly, and the parts produced are not so strong as
made in one piece. Seeing, however, that the metal must in most cases be wrought
they would be if each were
or malleable it has been very difficult and expensive to make each part in one
piece by welding. The object of my present invention is to provide means for
making each of the various parts of one piece of metal without rivetting, screwing
or welding several pieces together. For this purpose I stamp or press each part
out of a single sheet or plate of metal of suitable thickness and size in properly
formed moulds or dies by any known stamping or pressing machinery preferably,
in most cases, while the sheet or plate of metal is in a red-hot condition. These
parts are formed in the stamping or pressing process with suitable flanges or
other projections or parts whereby they can be screwed or rivetted together, or to
other parts so as to form the finished safe, which, when so made, is much stronger
and more satisfactory in many ways than a safe the principal component parts of
which are made up of several comparatively small pieces screwed or rivetted
together.
In the accompanying drawings
Figure 1 is a horizontal section of a safe constructed with parts made in
accordance with my invention, Figure 2 is a front view of same with the back and
bolt case frame and proofing pan removed,
Figure 3 a front view of the lock and bolt case frame and proofing pan with the
front or door plate removed,
Figure 4 is a horizontal section of one side of a similar safe constructed with
parts made in accordance with my invention, but with such parts made somewhat
differently from what is shown in Figure 1, and
Figures 5, 6 and 7 illustrate various modifications of the parts.
In Figure 1 the part A represents the front frame, and B the lining front,
these two parts being made in one piece stamped or pressed out of one sheet or
plate, and presenting, when so stamped or pressed out, the appearance shown in
Figure 2.
C in Figure 1 represents the lock and bolt case frame, and D the proofing pan
of the safe door. These two parts are also made in one piece stamped or pressed
out of one sheet or plate, and presenting, when so stamped or pressed out, the
appearance shown in Figure 3.
E in Figure 1 represents the back of the safe flanged up all round, the sides F
and the top and bottom being rivetted to the flanges of the back E, and A¹ of
the front A.
G in Figure 1 represents the lining the back, sides, top and bottom of which, in
cases where the dimensions of the safe are small enough to allow of it, I stamp or
press out of a single sheet or plate, and rivet at the front edges to the lining
front B.
H in Figure 4 represents the back of the safe and H¹ the sides, the back, sides,
top and bottom, in cases where the dimensions of the safe are small enough to
allow of it, being stamped or pressed out of a single sheet of plate, and rivetted
by a butt strap I, or otherwise, to the front frame A.
J in Figure 4 represents the back of the lining made in one piece flanged up all
round, the sides J₁ and top and bottom being rivetted to the flanges J' of the back,
and to the lining front B.
In Figure 4 the front frame A is shown stamped or pressed out of one sheet or
plate, the lining front B out of another sheet or plate, and the two rivetted
together at K.
In the modification illustrated in Figure 5 the back J the sides J¹ and the top
and bottom of the lining are stamped or pressed up in one piece out of a single
sheet or plate and rivetted to the lining front B.
. In the modification illustrated in Figure 6 the back J, the sides J¹ and the top

page_text: and bottom of the lining, and the lining frame B are stamped or pressed up in one
piece out of a single sheet or plate, and if desired the front frame A may also be
formed at the same time, as shown in dotted lines.
In Figure 7 the lock and bolt case frame C is shown stamped or pressed out of
one sheet or plate, the proofing pan D out of another sheet or plate, and the two
rivetted together at M.
The stamping or pressing of the parts out of sheets or plates of metal may be
performed in any suitable pressing inachine with the aid of top and bottom dies of
the usual well known construction, and may be effected in one or more operations
according to circumstances.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
First. Making the front frame of a safe in one piece by stamping or pressing
the same from a sheet or plate of metal, as described with reference to Figure 4 of
the drawings.
Second. Making the lining front of a safe in one piece by stamping or pressing
the same from a sheet or plate of metal, as described with reference to Figure 4
of the drawings.
Third. Making the front frame and the lining front of a safe in one piece by
stamping or pressing the same from a sheet or plate of metal, as described with
reference to Figure 1 of the drawings.
Fourth. Making the lock and bolt case frame of a safe door in one piece by
stamping or pressing the same from a sheet or plate of metal, as described with
reference to Figure 7 of the drawings.
Fifth. Making the proofing pan of a safe door in one piece by stamping or
pressing the same from a sheet or plate of metal, as described with reference to
Figure 7 of the drawings.
Sixth. Making the lock and bolt case frame and the proofing pan of a safe door
in one piece by stamping or pressing the same from a sheet or plate of metal, a
described with reference to Figure 1 of the drawings.
Seventh. Making the back, sides, top and bottom of a safe in one piece by
stamping or pressing the same from a sheet or plate of metal, as described with
reference to Figure 4 of the drawings.
Eighth. Making the back, sides, top and bottom of the lining of a safe in one
piece by stamping or pressing the same from a sheet or plate of metal, as described
with reference to Figure 5 of the drawings.
Ninth. Making the back, sides, top and bottom of the lining, and the lining
front of a safe in one piece by stamping or pressing the same from a sheet or
plate of metal, as described with reference to Figure 6 of the drawings.
Tenth. Making the back, sides, top and bottom of the lining, the lining front
and the front frame of a safe in one piece by stamping or pressing the same
from a sheet or plate of metal, as described with reference to Figure 6 of the
drawings.
