PROVISIONAL SPECIFICATION.
Improvements in and relating to Metal Boxes.
1. CHARLES MANNERS, Rock Valley Mills, Mansfield, Manufacturer, do hereby
declare the nature of this invention to be as follows:-
My invention relates to improvements in metal boxes; said boxes being stamped
out of, and in one sheet, of any suitable metal; thus, dispensing with the use of
solder &c., for joining the sides and ends together.
.
In accordance with my invention, I stamp or punch out the sheet of metal
forming the box, in one piece; in which the two end pieces are made of double
lengths. The two side pieces are folded over as if forming an ordinary square, or
any other shaped metal box; but, the four ends of the said side pieces have a small
portion of same bent round at right angles. The two end pieces first above
mentioned are then folded over, these being of double length; they are bent over,
and the ends of same are entered inside the box, thus forming a dovetail for the
four ends of the two side pieces.
The ends are then punched at the top, thus firmly holding all the four corners
of the box securely together without the aid of solder &c.
Or, otherwise I may bend at right angles a small portion at the top of the four
ends of the two sides of the box; and, also a small portion of the two end pieces,
instead of the whole length as hereinbefore described. The ends are then folded
over the four top pieces of the two sides of the box above referred to, which are
then punched in the same manner as above set forth.
Dated this 4th day of January 1893.

COMPLETE SPECIFICATION.
Improvements in and relating to Metal Boxes.
I, CHARLES MANNERS, of Rock Valley Mills, Mansfield, Manufacturer 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:
My invention relates to improvements in metal boxes and its object is to dispense
with the use of solder and the like for joining the sides and ends together. Boxes
constructed in accordance with this invention will be found to be very neat in
appearance and finish, and very light and particularly adaptable for use in sending
samples through the post &c.
And in order that this my invention may be fully understood I will now discribe
same with reference to the accompanying sheet of drawings upon which
Figure 1 is a plan of the sheet of metal as stamped and ready for folding into the
shape required.
Figure 2. is a cross sectional elevation of the box when formed, and, Figure 3 is
a longitudinal section of the same.
Similar letters of reference indicate like parts in each of the figures.
Now, in accordance with my invention, I stamp or punch out the sheet of metal
of which the box is to be formed as shewn particularly in the plan view Figure 1.
The box is thus formed of one piece of metal only. The portion marked a forms
the bottom of the box, those parts marked b form the sides and the parts c make
the ends of the box, the dotted lines b, c in Figure 1 indicating where the sides

page_text: and ends are turned up from the bottom of the box. The extremities 6 of the
sides I bend over inwardly at right angles as will be best seen in Figures 2 and 3
of the drawings; and the ends c I form of a length equal to about double the height
of the box. When the sides have been bent into position the ends c are brought
up as shewn in Figure 2 and then folded at the dotted lines marked c² over the
flanged ends b² of the sides see Figure 3.
:
The ends are then punched at the top thus firmly holding all the four corners of
the side pieces securely, together without the aid of solder or the like and making a
neatly finished metal box."
As a modification I may when preferred, instead of making the extremities b² of
the sides b the full width of said sides as shewn, simply have a folding lug at the
upper ends as defined by the dotted lines marked in Figures 1 and 2 and then
shorten the ends c as marked by the dotted lines y, thus effecting a saving in the
metal and lessening the weight of the box.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:-
First. The improvements in and relating to metal boxes, substantially as and for
the purposes hereinbefore described and shewn.
Second. Metal boxes constructed of one piece of metal, stamped, shaped, and
folded substantially as herein described and shewn in the drawings.
Dated this 5th day of October 1893.
