I WILLIAM WILLIAMS, of N° 5 Chancery Lane, in the County of Middlesex,
IMPROVE-
Gentleman, do hereby declare the nature of the said Invention for
MENTS IN MACHINERY OR APPARATUS FOR MANUFACTURING BOXES FOR HOLDING
TIN PLATES," to be as follows:-
This Invention relates to Improvements in machinery or apparatus for manu-
facturing boxes for holding tin plates. Instead of constructing such boxes of
wood I propose to construct them of sheet iron and for this purpose I employ a
stamping press with adjustable sides regulated by means of screws so as to
manufacture any size of box.
The plunger of the press is raised by means of a double cam and the shaping of
the sheet metal is effected either by the weight of the block and plunger or by the
use of springs or steam power acting in co-operation therewith.

I WILLIAM WILLIAMS 5 Chancery Lane, London W.C. 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 machinery or apparatus for manu-
facturing boxes for holding tin plates.
Instead of constructing such boxes of wood I propose to construct them of sheet
iron and for this purpose I employ a stamping press with adjustable sides regulated
by means of screws so as to manufacture any size of box-The plunger of the press
is raised by means of a double cam and the shaping of the sheet metal is effected
either by the weight of the block and plunger or by the use of springs or steam
power acting in co-operation therewith.
In order that my Invention may be more fully understood I have hereto
annexed a sheet of Drawings illustrative thereof-Fig. 1 represents elevation of
stamping press adapted for working by steam power. A is the framework
provided with vertical guides B for steadying the plunger C-To the upper
portion of the plunger is attached a piston rod D connecting the plunger with a
piston E working in the cylinder F-Steam is admitted to the cylinder and
allowed to escape therefrom by means of the three way valve G-Ĕ is the die
or mould consisting of a rectangular box rather larger than the plunger-The
sheet iron of which the box is to be made is placed over the mould H and forced
thereinto by the plunger C-If desirable the mould H may have moveable sides as
shewn in Fig. 2, so that various sizes of boxes may be made in the same mould by
altering the plunger to correspond.
Instead of steam power acting directly on the plunger I may employ a cam or
wiper J for the purpose of raising the same as shewn in Fig. 3.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is―
First. The manufacture of boxes for containing tin plates out of sheet metal
instead of wood substantially as herein specified.
Secondly. The employment of machinery for the purpose constructed and
operated substantially as herein shewn and described.
Dated this 16th day of June 1886.
