of the Commissioners of Patents, with his Petition, on the 30th
June 1869.
I, MICHAEL TURNOR, of Birmingham, in the County of Warwick,
Metallic Pen Manufacturer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN THE MANUFACTURE OF METALLIC AND OTHER
BOXES," to be as follows:-
My Invention consists of the improvements herein-after described in
the manufacture of metallic and other boxes.
Boxes made according to my Invention are specially fitted to hold
steel pens and other small articles, but may also be used for various
other purposes.
In making metallic boxes according to my Invention I make the
bottom and one of the longer sides of the box out of one blank or
plate of sheet metal, and I make the other three sides of the box out
of one piece of sheet metal. The lid I make of a third piece of
sheet metal. The lid is jointed to that longer side of the box which
forms part of the first-named blank by an ordinary hinge joint, and the
other three sides of the box are connected to the said bottom in

page_text: the following manner :-That part of the first-named blank of which
one of the longer sides of the box is formed has near each of its ends
a small projecting piece or car; the said part is bent at or nearly at
right angles to the part of which the bottom of the box is formed. The
edges of the three sides of the bottom plate are turned up, so as to form a
bead or hollow rim. The strip or blank from which the other three sides
of the box are made is of a length sufficient when bent at the required
places to form the said threo sides, and an inner side at the back of tho
box, the ends of the blank forming the said inner side being brought
together at or near the middle of the longer side of the box formed
in one piece with the bottom. This inner side is situated against that
side of the box to which the lid is hinged so that the said side in the
finished box is of a double thickness of metal. The short sides or onds,
and the longer sides situated between thom are turned outwards at their
lower edges so as to form a slight flange. On putting the parts of the
box together the said flange is inserted into the hollow bead or rim of
the bottom of the box, and in order to fix the said sides and bottom
together the two projecting cars herein-before described are bent down
against the back of the box, thereby preventing the yeilding of the sides
of the box and preventing the escape of the said flange from the hollow
bead or rim of the bottom. Instead of fixing the sides to the bottom in
the way described the parts may be connected together in the following
manner-The bottom and sides have the beads and flanges respectively.
herein-before described. The side formed out of the same blank as the
bottom has at its ends beads or rims, and the ends of the blank forming
the three sides have flanges which take into the last described beads. A
strip of metal equal in length to one of the longer sides of the box is,
fixed at the back of the box and constitutes a stay piece which prevents
the yeilding of the ends of the box, and the escape of the flanges from
the hollow beads; or the said ends may be fixed by soldering. Boxes
may be made from cardboard or other non-metallic material in ways
essentially similar to those described with respect to metallic boxes
excepting that the lid is connected to the box by a flexible joint instead
of by a hinge.
