A NEW OR IMPROVED METHOD OF MANUFACTURING METAL BOXES
Year: 1859

page_text: LETTERS PATENT to Michael Turnor, of Birmingham, in the County of
Warwick, Metallic Pen Manufacturer, for the Invention of "A NEW
OR IMPROVED METHOD OF MANUFACTURING METAL BOXES."
Sealed the 5th June 1860, and dated the 20th December 1859.
PROVISIONAL SPECIFICATION left by the said Michael Turnor at the
Office of the Commissioners of Patents, with his Petition, on the 20th
December 1859.
I, MICHAEL TURNOR, of Birmingham, in the County of Warwick, Metallic
Pen Manufacturer, do hereby declare the nature of the said Invention for
"A NEW OR IMPROVED METHOD OF MANUFACTURING METAL BOXES," to be as
follows:-
My Invention relates to the manufacture of such metal boxes as have a
square or other rectangular form, and consists in forming the said boxes from
sheet metal in the manner herein-after explained. Metal boxes made accord-
ing to my Invention are suited to hold metallic pens, leads, matches, and other
articles.
I will explain my Invention with reference to the manufacture of an oblong
metal box. I cut from sheet metal, by means of a press or otherwise, a blank
of such form that when the sides and ends of the said blank are bent at right
angles to the other portion, they form respectively the sides and ends of
the box. On opposite sides of the ends of the blank are left tongues or ears,
which said tongues or ears stand at right angles to the sides of the box when
the sides and ends of the blank have been raised by suitable dies or tools. By
means of suitable dies or tools, grooves are formed in the top edges of the
sides of the box, in which grooves the lid slides. In order to bind the sides

page_text: and ends of the box securely together, the tips or ends of the before-mentioned
tongues on the ends of the box are bent at right angles to the said tongues,
and by pressing the said tongues against the sides of the box the bent ends of
the tongues enter and pass through slits or piercings made in the said sides.
By means of a burnishing tool the tongues are pressed against the sides of the
box, and the ends of the said tongues projecting into the box clenched in the
interior of the said box. The sides and ends of the box are thus bound firmly
together, and by sliding a lid in the grooves at the mouth of the box the said
box is complete. I prefer to make the slits or piercings in the sides of the
box into which the tongues enter before the sides and ends are raised from
the blank.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Michael Turnor in the Great Seal Patent Office on the
19th June 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, MICHAEL
TURNOR, of Birmingham, in the County of Warwick, Metallic Pen Manufac-
turer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of December, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Michael Turnor, Her special licence that I, the said Michael
Turnor, my executors, administrators, and assigns, or such others as I, the
said Michael Turnor, 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 "A NEW
OR IMPROVED METHOD OF MANUFACTURING METAL BOXES," upon the condition
(amongst others) that I, the said Michael Turnor, my executors or administra-
tors, 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 Michael Turnor, do hereby declare
the nature of the said Invention, and in what manner the same is to be

page_text: performed, to be particularly described and ascertamed in and by the ionowing
statement thereof, that is to say :-
My Invention relates to the manufacture of such metal boxes as have a
square or other rectangular form, and consists of the method herein-after
particularly described, and illustrated in the accompanying Drawing, of manu-
facturing the said boxes from sheet metal. Metal boxes made according to
my Invention are suited to hold metallic pens, leads, matches, and various
other articles.
I will explain and illustrate my Invention in its application to the manu-
facture of an oblong metal box, from which explanation and illustration the
application of my Invention to the manufacture of boxes of other rectangular
or nearly rectangular forms will be readily understood. The same letters are
employed to indicate the same parts in the several Figures.
In carrying my Invention into effect, I cut from sheet brass or other
suitable metal or alloy of metal, by means of a pair of dies, working in a press
or otherwise, a blank of the form represented in Figure 1 of the Drawing.
I next pierce the said blank, Figure 1, with slits or piercings, as represented
in Figure 2, and marked e, e; the object of the said slits or piercings is herein-
after explained. The blank, Figure 2, is of such a form that when the
sides a, a, and ends b, b, are bent or raised on the dotted lines at right angles
to the portion c, they form respectively the sides and ends of the box, as
represented in Figures 3, 4, and 5, which represent an end elevation, plan,
and side elevation respectively of a partially formed box raised from the blank,
Figure 2, as described. On opposite sides of the ends b, 2, of the blank,
Figure 2, tongues or cars d, d, are situated, the said tongues standing at right
angles to the sides of the box, when the blank has been raised, as seen in
Figures 3 and 4, and marked d, d, in the said Figures. When the partially
formed box has assumed the form Figures 3, 4, and 5, it is next operated upon
by a pair of suitably shaped tools, by which the upper edges of the sides a, a³,
of the box are grooved, as shown in the end and side elevation of a box in
this stage of its manufacture, represented in Figures 6 and 7, the said grooved
edges being marked f,f; in the said grooved edges f, f, the lid of the box
slides. In order to bind the sides and ends of the partially formed box,
Figures 6 and 7, securely together, the tips or ends of the tongues or ears d, d,
at the ends of the box are bent at right angles to the said tongues, as repre-
By bending and
sented in the plan of a partially formed box, Figure 8.
pressing the tongues d, d, so shaped against the sides of the box, the bent ends
or tips enter and pass through the slits or piercings e, e, in the sides of the box,
as represented in the plan and side elevation, Figures 9 and 10. By means

page_text: of a pressing or burnishing tool or otherwise, those portions of the said
tongues d, d, outside the box are pressed against the sides of the said box, and
the tips or ends of the said tongues d, d, projecting into the box are clenched
in the interior thereof. Figures 11, 12, and 13 represent in longitudinal
transverse and horizontal sections respectively a box in which the tongues d, d,
have been pressed and clenched as described; and Figure 14 represents a
perspective view of the box. By the pressing and clenching of the tongues d, d,
the sides and ends of the box are bound firmly together. The box is thus
made, and by sliding a lid in the grooves f, f, at the mouth of the box the said
box is complete. The box may afterwards be finished and its form perfected,
and at the same time ornamented, by another pair of dies.
which I use in making the box Figures 11, 12, 13, and
cutting out and piercing the blank, Figures 1 and 2, raising the blank,
Figure 2, into the form of Figures 3, 4, and 5, forming the grooves f, f, at the
sides of the box, and finally bending the tongues d, d, are worked in an
ordinary press or otherwise, the said dies or tools having the necessary forms
to cut and pierce the blank and to raise the said blank into a box, in the
manner before described.
The dies or tools
14, that is to say,
Having now described the nature of my Invention, and the manner of
carrying the same into effect, I wish it to be understood that I do not limit
myself to the precise details herein described and illustrated, as the same may
be varied without departing from the nature of my Invention; but I claim as
my Invention, the new or improved method of manufacturing metal boxes
herein-before described, and illustrated in the accompanying Drawing, that is
to say, manufacturing boxes of a square or other rectangular form from blanks
of sheet brass or other suitable metal or alloy, essentially in the manner before
explained and illustrated.
In witness whereof, I, the said Michael Turnor, have hereunto set my
hand and seal, this Eighteenth day of June, in the year of our Lord
One thousand eight hundred and sixty.
