PROVISIONAL SPECIFICATION.
Improvements in Canisters, Metallic Kegs, Drums, and the like.
I THOMAS AUGUSTUS PRINCE of 56 Vicarage Road, Tottenham in the County
of Middlesex Tin Plate Worker do hereby declare the nature of this invention to
be as follows :-
:-
Now it has been found that the flux used in soldering canisters metallic kegs,
drums and the like acts injuriously upon the contents of such receptacles and
various attempts have been made to construct vessels without soldering the parts
together. Vessels so made have however hitherto proved too weak to resist the
rough usage incidental to cartage and especially so to export.
Now the object of my invention is to construct canisters, metallic kegs drums
and the like without the aid of soldering or brazing which receptacles shall be
stronger when so made than if soldered in the usual way.
According to this invention I construct the body of canisters inctallic kegs,
druins and the like receptacles with a double seam in the usual way. I then
turn the bottom edge of the body in, parallel to the sides thereof. The edge
of the piece of metal forming the bottom is turned up all round approximately
to a right angle and then bent back again parallel to itself thus forming a channel
all round the bottom piece. The bottom piece with the channel downwards is
then placed in the body and forced down till the turned in edge of the body
engages with or entors the channel in the bottom piece. When the bottom
piece is in position the bottom portion of the vessel is placed between a suitable
mandrel and a suitablo roller and by this means the odgo of the body and that
of the bottom piece are closed tightly together whilst at same time a groove is
formed in the body completely surrounding the edge of the bottom piece and
by theso methods the bottom is effectually prevented from becoming detached
from the body.
The covers of metallic drums and kegs may also be formed in the same way
and the invention is also applicable to the manufacture of canisters which are
closed by flanged lids fitting a small orifice as both ends of such canisters may
be attached to the body in the manner hereinbefore described.

Improvements in Canisters, Metallio Kegs, Drums, and the like.
THOMAS AUGUSTUS PRINCE of 56 Vicarage Road Tottenham in the County
of Middlesex Tin Plate Worker 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 :—
Now it has been found in practice that the flux used in soldering metallic
canisters kegs drums and the like acts injuriously upon the contents of such
receptacles and several attempts have been made to construct such vessels without
soldering the component parts together. These attempts have however prior to
this invention been unsuccessful as the vessels made without solder have proved
too weak to resist the rough usage incidental to cartage and export. Now the
object of this invention is to construct metallic canisters kegs druins and the like
without the aid of solder or brazing, the said receptacles when so made-according.

page_text: to this invention-being as strong as if not stronger than when soldered in the
usual way.
According to this invention I construct the bodies of canisters metallio kegs
drums and the like receptacles with a double seam in the usual way. I then turn
the bottom edge of the body in parallel to the sides thereof. The edge of the
piece of metal forming the bottom is turnel up all round approximately to a right
angle and then beut back again parallel to itself thus forming a channel all round
the bottom piece. The bottom piece with the chaunel downwards is then placed in
the body of the vessel and forced down till the turned in edge of the body engages
with or enters tho channel in the bottom piece. When the bottom piece is in 1
position the bottom portion of the vessel is placed between a suitable mandrol and
a suitable roller and by this means the edge of the body and that of the bottom
pieco aro closed tightly together whilst at same time a groove is formed in the
body completely surrounding the edge of the bottom piece and by these methods
the bottom is effectually prevented from becoming detached from the body.
The covers of metallic drums and kegs may also be formed in the same way.
And in order that my said invention may be fully understood I will proceed to
explain the same with reference to the accompanying drawings in which :-
Fig. 1 represents a section of a mustard canister construoted according to this
invention with the bottom piece inserted in the body ready for closing.
Fig. 2 represents section of the same finished.
Fig. 3 is section of bottom of a canistor ready for insorting in the body.
Fig. 4 represents a partial section of the body of a canister showing turned
bottom edges ready to receive tho pioce of metal forming the bottom.
Fig. 5 shows another method of closing over the edges of the body and bottom
piece.
It will be understood that a space is left between the lines representing the
different pieces of metal for the sake of clearness but in practice the pieces of metal
forming the body and bottom of the canister or other receptacle are forced into
actual contact.
•
The same letters denote the same parts in all the figures.
a is the body of the vessel the lower edges of which are turned up inwardly at b
parallel to the sides cc: the edges of the bottom piece dare bent upwards and
then downwards so as to allow the portion to enter the channel g, formed of the
upturned portion of the body a. This bending may be done by stamping. When
the bottom of the canister keg or other receptacle is inserted into the body thereof
the said vessel is placed on a mandrel or block and the groove formed therein by
rolling or "wheeling" thus securing the sides e to the bottom d and preventing the
parts from becoming detached from each other. The groove also materially
strengthens the vessel. is the lid or cover stamped (as shown) from one piece of
métal in the usual way. This may be constructed in two pieces as herein specified.
In the case of canisters such for instance as are used to pack mustard and
particularly receptacles other than cylindrical in shape it will be found preferable to
partially secure the bottom to the sides by pressing or stamping as shown at Fig. 5
before forming the groove h. In this case the canister or other receptacle (when
the bottom is inserted as shown in Fig. 1) is placed bottom upwards on a block
under a drop stamp, press or ram carrying a hollow dio tapered internally at its
extreme top or a die having a tapered recess therein which on its descent forces the
edges of the bottom and sides into the position shown at Fig. 5. The groove as
shown at h (Fig. 2) is then formed in the manner herein before described. In some
cases the rolling may be dispensed with and the bottom and sides secured by
stamping or pressing only.
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 :-
1. Constructing the bodies of canisters, kegs, drums and the like receptacles

page_text: with a U shaped channel at the bottom thereof which channel is formed by turning
up inwardly the lower edgo thereof substantially as hereinbefore specified and for
the purpose stated.
2. In canisters, kegs, drums and the like receptacles the combination of a body a
having a U shaped channel g with a bottom piece d having a similar channel
therein substantially as heroinbefore described and shown by the accompanying
drawings.
3. Constructing metallic canisters kegs drums and the like receptacles without
the aid of solder substantially in the manner hereinbofore specified.
