I THOMAS HAY CAMPBELL of 15 Westbourne Park Villas Bayswater in the
County of Middlesex do hereby declare the nature of my Invention for IMPROVE-
MENTS IN THE MANUFACTURE AND OPENING OF HERMETICALLY CLOSED CANS
CASES OR BOXES FOR PRESERVED ARTICLES OF FOOD AND THE LIKE to bo
as follows:
This Invention relates to inprovements in opening and sealing Hermetically
closed Cans Cases or Boxes in all kinds & shapes of Cans Cases or Boxes, used for
the purpose of storing preserved articles of food and the like.
In any part of the lid used for Hermetically sealing Cans, Cases, or Boxes or
in some instances in the body of the Cans, Cases, or Boxes, I form a groove, loop
or space wherein I place a piece of metal of triangular or other suitable shape or
piece of wire made of any suitable material and I leave a portion or portions
thereof exposed to enable me to take up the same when opening the cans cases
or Boxes with a key or knife as hereinafter described.
In another method I adopt, I solder the lid of the Cans Cases or Boxes after
placing a cord or wire or a piece of metal into the groove or loop or space provided
for the same to the body of the Can, Case, or Box leaving no part or portion of
such cord wire or piece of metal exposed and when I require to open these Cans
Cases or Boxes, I press the pointed end or lower claw of the key or knife herein-
after more fully described through the groove loop or space containing the cord
wire or piece of metal until the cord wire or piece of metal is secured between the
claws of the key or knife and by then revolving the key or knife round the entire
circumference of the can case or Box the cord wire or piece of metal is made to cut
through the groove loop or space as aforesaid and liberates the lid from the body

page_text: of the can case or Box without in any way affecting or touching the contents of
the same.
The key or knife referred to is made of metal one end of which is cylindrical
and at the extremity thereof which is to be used for taking hold of the cord wire
or piece of metal,--which I use in the grooves loops or spaces as aforesaid-is in
shape similar to a pair of claws one claw being made longer than the other and
brought to a point and the shorter claw made square-the other end may be made
into a loop or any other suitable shape so as to make the holding thereof easy and
give leverage to the hand in order to assist the cutting through of the material in
which is placed the cord wire or piece of metal..

I THOMAS HAY CAMPBELL of 15 Westbourne Park Villas Bayswater in the
County of Middlesex Gentleman do hereby declare the nature of my Invention
for IMPROVEMENTS IN THE MANUFACTURE AND OPENING OF HERMETICALLY CLOSED
CANS CASES OR BOXES FOR PRESERVED ARTICLES OF FOOD AND THE LIKE and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :—
In any part of the lid A used for Hermetically closed cans, cases, or boxes or in
some instances in the body of the Cans Cases or boxes I form a groove loop or
space as shewn on Figs. 1 & 6 by the dotted lines II and in Fig. 2 the lid being
removed shews the groove itself II wherein I place a piece of metal of triangular
or other suitable shape or a piece of wire made of any suitable material, leaving
a portion of the same on the end or both ends exposed as at Figs. 1. 3. & 4 E E, so
as to enable me to take up the same when opening the Cans, Cases, or boxes with a
knife or key as hereinafter more fully described.
In another method employ I solder the lid A of the Cans, Cases, or boxes after
placing a cord, wire or piece of metal into the groove, loop, or space provided for
the same in the body of the Cans, Cases, or boxes leaving no part or portion of such
cord or wire exposed as shewn by Fig. 5 II and when I require to open these Cans,
Cases, or boxes I press the pointed end or lower claw of the key or knife hereinafter
described through the groove, loop, or space containing the cord wire or piece of
metal and then by revolving the said key or knife round the entire circumference
of the Can, Case, or box the cord or wire cuts through the metal forming or covering
the groove, loop, or space and the lid becomes liberated from the body of the Can,
Case, or box without in any way touching the contents and which can be taken
out of the Can, Case, or box without being injured or broken.
In some instances where I make the groove, loop or space in the body of the
Can, Case or box, I use a lid with one or more holes perforated through the same
and after putting the wire round the body of the Can, Case, or box and into the
groove, loop, or space provided therein, I draw the end or ends of the cord or wire
through the said hole or holes and fasten the same down with solder to the body
of the Can, Case, or box as at Fig. 3, E, E, and the opening of this Can, Case, or box
is similar to that above described.
The key or knife referred to is made of metal one end of which is usually
cylindrical and at the end which is to be used for taking hold of the cord, wire, or
piece of metal which I use in the grooves, loopes, or spaces as aforesaid—is in shape
similar to a pair of claws one claw being longer than the other and may be brought
to a point, the shorter claw is made square the other end may be made into a loop
or any other suitable shape so as to make the holding thereof easy and to give
leverage to the hand in order to assist the cutting through of the material of which
the Cans, Cases, or boxes are composed.

In some instances I also provide a hole through the lower end of the key or knife
as shewn by the dotted lines D on Fig. 7 which enables me to obtain a more certain
hold in taking up the ends of the cord, wire or piece of metal in order to effect the
opening of the Cans, Cases, or boxes.
"
Fig. 1 is an elevation of an ordinary hermetically closed Can or Case A is the
body of the Can or Case B the lid-soldered down to the body of the Can or Case
the whole way round at C. C. The dotted lines I I indicate the position of the
metal cord or wire secured in the groove loop or space made in this instance in the
body of the Can or Case and E E are the ends of the metal cord or wire coming out
of holes perforated in the lid of the Can or Case at F. F.
Fig. 2 Illustrates the same Can or Case with the lid removed and shewing the
groove or loop in the body of the Can or Case at I I.
Fig. 3. is another ordinary meat can or case with the groove or loop I I in the
lid and not in the body of the Can or Case as before mentioned and E. E. are the
ends of the metal cord or wire coming out of the groove, loop or space.
Fig. 4 is a perspective view of a sardine Can or Case II representing the groove
or loop prepared in the lid of the Can or Case and E. E. shew the ends of the
wire coming out of the groove or loop and fastened down to the body of the Can
or Case and C, C, is where the lid is sealed.
Fig. 5 is another ordinary Can Case or box with the groove or loop in the lid
without any portion of the wire or metal cord being exposed.
Fig. 6 shews a can with the wire attached to it in a similar way to Fig. 1. but
taller.
Fig. 7. is an elevation of the key or knife as described with a perforation in the
longer claw, as shewn by the dotted lines D.
In the above description of the various Figs. shewn on the drawing the same
letters of reference have connection with similar parts on the Figs.
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
1st The improved method of using inserted wires or metal cords in the lids or
.bodies of the intended Hermetically closed Cans, Cases, or boxes substantially as
before described and shewn in the accompanying drawing.
2nd The means of opening the Hermetically closed Cans, Cases, or boxes with
the key or knife before described and shewn on the drawing.
3rd The Cans, Cases, or boxes or any mere modification of the same as described
and shewn on accompanying drawing.
