IMPROVEMENTS IN TINS OR RECEPTACLES FOR PRESERVED FOOD AND OTHER ARTICLES OR SUBSTANCES." PROAL SPECIFICATION
Year: 1876

page_text: LETTERS PATENT to John James Lundy, of the Oil and Color Works, Leith,
near Edinburgh, North Britain, and 56, Leadenhall Street, in the City of
London, Color, Varnish, and Grease Manufacturer and Oil Refiner, for the
Invention of "IMPROVEMENTS IN TINS OR RECEPTACLES FOR PRESERVED FOOD
AND OTHER ARTICLES OR SUBSTANCES."
PROVISIONAL SPECIFICATION left by the said John James Lundy at the
Office of the Commissioners of Patents on the 20th March 1876.
JOHN JAMES LUNDY, of the Oil and Color Works, Leith, near Edinburgh, North
Britain, and 56, Leadenhall Street, in the City of London, Color, Varnish, and
Grease Manufacturer and Oil Refiner. "IMPROVEMENTS IN TINS OR RECEPTACLES
FOR PRESERVED FOOD AND OTHER ARTICLES OR SUBSTANCES."
My Invention has for its object constructing and closing tins or like receptacles
in such a manner as to enable the same to be opened or the covers to be removed
without the employment of knives, keys, or other tools ordinarily required for that
purpose. In order to effect this object I make the cover of the tin (when the latter
is of a cylindrical shape) in the form of a disc with an annular rim or flange
extending upwards therefrom, and I attach the cover so prepared to the body of the
tin by means of a strip or band of tin or other suitable metal, which is wound
round and soldered both to the rim or flange of the cover and to the top of the tin.
This metal strip or band I make of sufficient length that an unsoldered portion shall
be left at one end overlapping or projecting beyond the other end of the soldered
portion of the strip or band, so that by the act of simply laying hold of the
overlapping or projecting end and pulling it back away from the tin, the strip or
band will become unwound or unsoldered, and the cover will be detached by means
of the forefinger and thumb without any knife, key, or tool whatever.
My Invention is also applicable to tins or like receptacles of a square, rectangular,
or other suitable form, the cover being made of a corresponding shape.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John James Lundy in the Great Seal Patent Office on the 5th
September 1876.
JOHN JAMES LUNDY, of the Oil and Color Works, Leith, near Edinburgh, North
Britain, and 56, Leadenhall Street, in the City of London, Color, Varnish, and
Grease Manufacturer and Oil Refiner. "IMPROVEMENTS IN TINS OR RECEPTACLES
FOR PRESERVED FOOD AND OTHER ARTICLES OR SUBSTANCES."
My said Invention has for its object constructing and closing tins or other
metallic canisters or like receptacles in such a manner as to enable the same to be
opened or the covers to be removed without the employment of the knives or other
tools ordinarily required for that purpose. In order to effect this object I make the
cover of the canister (when the latter is of a cylindrical shape) in the form of a disc
with an annular rim or flange extending upwards therefrom, and I attach the cover
so prepared to the body of the canister by means of a strip or band of tin or other
suitable metal, which is wound round and soldered or fastened both to the rim or
flange of the cover and to the top of the canister without the cover being attached
to the body of the canister itself, whereby it can be separated without leaving any
jagged edge, which is left by every other means of opening hermetically scaled tins
or other metal canisters. This metal strip or band I make of sufficient length that
an unsoldered or unfastened portion shall be left at one end overlapping or projecting
beyond the other end of the soldered or fastened portion of the strip or band, so
that by the act of simply laying hold of the overlapping or projecting end by the
finger and thumb, and pulling it back away from the canister the strip or band will
become unwound or unsoldered, and the cover will be entirely detached without
damage to the remaining portion of the canister, which can then be emptied of its
contents and be used for other purposes thereafter.
The annexed Drawing illustrates a canister constructed in accordance with my
Invention.
Figures 1 and 2 represent respectively a plan and elevation of the canister closed,
and Figure 3 represents a perspective view of the canister partially opened. a is
the body of the canister; b is the disc constituting the cover with its annular rim or
flange b¹, extending upwards or downwards; c is the metal strip or band which is
wound round and soldered or fastened both to the rim or flange b¹ of the cover and
to the top of the body a of the canister so as to entirely encircle the two, c¹ repre-
senting its unsoldered or unfastened portion projecting beyond the end c² of the
soldered or fastened portion. When it is required to open the canister the operator
lays hold of the end c¹ with the finger and thumb and pulls it back away from the
canister, whereby the strip or band c will become unwound or unfastened in the
manner illustrated in Figure 3, in which the strip or band is represented as partially
unwound, the line d representing the abutting edges of the top of the body a and
of the cover b, which become completely detached the one from the other when the
strip or band c is entirely unwound.
It is obvious that the cover b with the strip or band c may be arranged at the
bottom of the tin, made open for the purpose in lieu of at the top, if preferred.
My Invention is also applicable to tins or other like metallic canisters or recep-
tacles of a rectangular or other suitable form, the cover being made of a corre-
sponding shape.
Having now described and particularly ascertained the nature of my said Inven-
tion, and the inanner in which the same is or may be used or carried into effect, I
would observe in conclusion that what I consider to be novel and original, and there-
fore claim as the Invention secured to me by the herein-before in part recited Letters
Patent is, constructing and closing tins and other like metallic canisters or recep-

page_text: tacles, substantially in the manner herein-before described and illustrated by my
Drawings.
In witness whereof, I, the said John James Lundy, have to this my Specifica-
tion set my hand and seal, this Second day of September, One thousand
eight hundred and seventy-six.
JOHN J. LUNDY. (L.S.)
