COMPLETE SPECIFICATION.
Improvements in Apparatus for the Manufacture of Metal Boxes.
I, JOHN THOMSON PAUL, of Grove Works, Brandfield Street, Edinburgh, in
the County of Midlothian, North Britain, 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 has for its object to provide apparatus for facilitating and
expediting the bevelling and clasping, closing in or fixing the bottom of the box
to the body of it.
In order that my invention may be properly understood and readily carried into
effect I have hereunto appended one sheet of drawings in the several figures of
which corresponding parts are marked with the same letters of reference.
Figure 1 is a view of the under side of the closing die or hammer with the
hangers or shutters to be hereafter described hanging or open.
Figure 2 is a similar view showing them closed.
Figure 3 is a view of the bottom of the box in position before being placed on
the sliding mandrel.
Figure 4 is a section of Figure 1 showing portion of box in position for being
operated upon.
Figure 5 is a section showing the box being operated upon.
Figure 6 is an enlarged view of Figure 5 but showing only one of the hangers
or shutters.
Figure 7 is a view of part of box after having been operated upon.
In carrying out my invention I rivet or otherwise fix to the under-side of the
hammer or closing die A having a bevelled edge a, a square or other shaped
block B to which there is hinged hangers or shutters C also provided with bevelled
edges c.
The modus operandi is as follows:-The sheet of tin or other metal forming the
bottom D of the box having been cut and provided with a turned up edge dis
placed in position in the bottom E of the box so that the turned up edge d sits in
between the bent-over edge e of the bottom of the box as shown in Figure 3.
The box is then placed over a sliding mandrel F which is pushed under the
closing die or hammer A as shown more particularly in Figure 4. The closing
die or hammer A then falls when the hangers or shutters C spread out or close, as
seen more particularly in Figures 2, 5, and 6, when their bevelled edges c press
hard against the turned over edge d of the bottom D of the box, while the edge a of
the closing die or hammer A going outside of the bottom of the box, simultaneously
presses against it thereby clasping or closing in the bent-over edge d of the bottom
of the box, between the turned over edge e and the body of the box, thereby
completely clasping the two together as seen more particularly in Figures 5 and 6.
The bottom end of the box at the same time becomes slightly bevelled as shown
more particularly in Figure 7 by means of the bevelled edge on the hammer or
closing die, so that it will be ready for the final operation, which, forming no part
of my invention need not be herein further described.
It is to be understood that in place of having the hangers or shutters hinged
they may be so arranged as to be capable of sliding out and in and so effect the
same obiect.

page_text: 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 :-
In apparatus for the manufacture of metal boxes, in combination with the
closing die or hammer A having a bevelled edge a, the block B and hangers or
shutters C with bevelled edges c all operated substantially in the manner and for
the purpose herein before described and illustrated on the accompanying sheet of
drawings.
Dated this 1st day of October 1896.
