improvements in the Manufacture of Metal Bottles, Casks, Kegs, or
other Vessels of the like kind, and in Machinery therefor.
I, DANIEL CLARK, foreman to Messieurs B. Noakes and Company of the Tin Plate
Works, Dockley Road, Bermondsey in the County of Surrey Manufacturers do hereby
declare the nature of this invention to be as follows:-
My Invention relates to putting on the bottoms or ends of bottles, casks, cans, kegs,
such as are ordinarily used to hold oil, varnish, printer's ink, paint, soft soap and for
similar purposes, and constructed of sheet metal such as iron, or tinned plate."
The ordinary method in which such a vessel is manufactured by machinery (such
for instance as a canister of cylindrical shape) consists in taking a cylindrical tube
formed out of tinned plate or other sheet metal, flanging out its lower edge then
fitting upon the flange so formed a circular plate having its outer edge turned up so
as to fit upon the flange, and having a recess extending across the plate. The can is
then held by its top and bottom between two revolving chucks, and a revolving wheel
then brought to bear upon the outer edge of the end plate turns the outer edge in
over the tube flange. Afterwards the projecting flange upon the tube together with
the edge of the bottom plate which has been closed over it are gradually pressed by
means of the revolving wheel or hammer against the side of the tube all round so as
to make a very firm and solid joint only slightly projecting.
The recess in the end plate is provided in order that the bottom or end may fit and
enter a distance within the tube or body; and this is necessary because the revolving
hammer when closing the joint must have a bearing for resistance and this is provided
by the revolving mandril or chuck fitting into the recess so that the revolving wheel
or hammer exerts its pressure against the outer edge of the mandril in closing the
joint. But bringing the bottom plate into this shape requires special dies and a soft
metal sheet both of which are expensive.
By my improvements I do away with the recess in the end or bottom and use a
bottom plate quite flat with the outer edge only turned up and in closing the joint
I introduce a revolving mandril into the interior of the can. In other respects I close
the joint as before.

to be particularly described and ascertained in and by the following statement :-

In order that my said invention may be fully understood and readily carried into
effect I will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side elevation of the cylindrical body of a keg or other vessel flanged
in the usual manner at a. a.
Figure 2 is a section of the bottom or end as it would heretofore have been made.
It is stamped as will be seen with a cylindrical flange b¹ and also with a recess b² on
the outer side and a corresponding projection on the inner side.
The sides of the projection at 6, 62*, are cylindrical and the dimensions are such
that the sides 6× fit accurately into the cylindrical body.

page_text: This formation of the bottom or end is necessary where the bottom or end is fixed
by the process heretofore resorted to which consists in clamping and holding the keg
or vessel together with its end plate between two parallel circular discs one at either
end and rotating the vessel together with the discs whilst so held. One of these discs
has simply a circular groove in it to receive the end of the cylinder or body and so to
truly centre it in the machine. The other disc is made to fit into the recess 6² in the
end plate which is to be applied.
Figure 3 shews the flanged extremity of the body; the end plate and the disc
entering the recess in the end plate when all are in place.
In this figure c, is the revolving disc and d represents the wheel hammer or tool
which as usual is employed to bend over the flange b¹.
I would remark that in this and some other of the figures a narrow space is shewn
between parts which really are in contact; this is done in order that the construction
may be more readily seen as the thickness of the metal is so small that otherwise the
parts could not be very clearly shewn.
Figures 4. 5 and 6 illustrate the successive operations of bending the flanges 6
and a as ordinarily performed. It will be seen that the pressure exerted by the tool d
is sustained by the edge of the disc c, which as the disc enters within the circum-
ference of the cylinder a it is in a position to do.
When operating in accordance with my invention the cylindrical body as shewn by
Figure 1 is placed upon a metal block or drum whicn fits it accurately and extends up
to the extremity which is to receive the end plate. This drum takes the place of one
of the discs or clamping plates ordinarily employed; it is so mounted that it can
rotate freely. The end or bottom to be applied to the cylindrical body a may be made
in the manner shewn in section by Figure 7 that is to say without any recess or it
may for ornament or to give a finish to the article be made with a shallow recess but
if so the recess must not extend up to the walls of the cylindrical body for it is
necessary to my method that these walls should be in contact with the drum right up
to the end where the flange a¹ is formed upon it.
When the cylindrical body has been placed on the drum and the end plate applied
the drum is brought under the upper disc of the machine and this is set down upon it
until the end plate becomes nipped and held between the disc and the end of the drum.
Figure 8 represents the drum (here marked e) with the parts in position upon it.
The machine is now set in motion and whilst the keg or vessel is rotating the tool d is
applied to turn the flanges as before but with this essential difference that the pressure
exerted by the tool is sustained by the drum e and not by the disc c.
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 :-
:―
1. Putting on the ends of metal bottles, casks, kegs, or other vessels of the like kind
in the manner herein described that is to say, by mounting the cylindrical body on a
block or drum which fits within it and extends to the flanged end of the body; by
applying a flanged end plate made without an interior recess fitting the cylindrical
body; by causing the end plate to be nipped and held between the end of the block or
drum and an outer disc; and by turning the flanges whilst the apparatus revolves
with a tool the pressure of which is supported by the block or drum within the body.
2. My improvements substantially as described in the manufacture of metal bottles
casks kegs or other vessels of the like kind and in machinery therefor.
