Improvements in the Covers of Vessels for Containing Fire-
extinguishing Fluids, the said Improvements being also
Applicable to Vessels for Containing other Liquids and
Substances.
1, WILLIAM HAY HANNAY of 22 Hope Street, in the City of Glasgow, Oil
Merchant, do hereby declare the nature of this invention to be as follows :-
This Invention which consists in improvements in cases for containing fire
extinguishing fluids has reference to the lids or covers of such cases and it has
for its object to provide a lid or cover which whilst being fluid tight shall when
occasion arises be capable of being easily torn or fractured for discharge of the fluid
contents of the case. To that end the lid or cover is under the Invention composed
of lead, capsule metal or other soft metal, which is dished into shape and soldered
or otherwise tightly secured to the end of the case. Through the soft metal cover
there is passed the two extremities of a piece of wire these extremities being
folded close up to or against the under side of the lid the holes through which
the wire passes and which are preferable at or near the circumference or side of
the lid being rendered fluid tight by solder or otherwise. The loop of wire remaining
at the outside of the lid serves as a means for hanging up the casing and when it is
necessary to use the contents by jerking the casing downwards the thin capsule
metal, lead or equivalent lid is torn by the portions of the wire at its interior and an
opening for the discharge of the contents is thereby made.
The improved cover is also applicable to vessels for containing paint, oils and other
liquids and substances.

COMPLETE SPECIFICATION.
Improvements in the Covers of Vessels for Containing Fire-
extinguishing Fluids, the said Improvements being also
Applicable to Vessels for Containing other Liquids and
Substances.
1, WILLIAM HAY HANNAY, of 22 Hope Street, in the City of Glasgow, Oil
Merchant, 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 which is illustrated in vertical section at figure 1, and in plan
at figure 2, of the accompanying drawings consists in improvements in the lids or
covers of vessels or cases for containing fire extinguishing fluids and it has for its
object to provide a lid or cover which whilst being fluid-tight shall when_occasion
arises be capable of being easily torn or fractured for discharge of the fluid
contents of the case. To that end the lid or cover a, is, under the Invention,
composed of lead, capsule metal or other soft metal, which is dished into shape and
soldered or otherwise tightly secured to the end of the case b, an enclosing ring c,
being also preferably soldered around the cover. Through the soft metal cover a,
there is passed one extremity of a piece of wire d, the wire being laid in a circle
against the underside of the lid and soldered in position. The hole through which
the wire passes and which is preferably near or at the circumference or side of the
lid is rendered fluid tight by solder or otherwise. The part d', of the wire remaining
Price 5d.1

page_text: at the outside of the lid is folded into a loop and holds a ring e, which serves as a
means for hanging up the case b. When it is necessary to use the contents;-by
jerking the casing downwards against the resistance of the nail or hook on which
the ring e, is bung, the thin capsule metal, lead, or equivalent lid a, is torn by the
portion of the wire at its interior and an opening for the discharge of the contents is
thereby made.
Under a modification both ends of the wire d, may pass to the interior of the
lid the part of the wire projecting at the outside being formed into a loop for hanging
up the casing.
The improved cover is also applicable to vessels for containing paint, oils and other
liquids and substances.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the saine is to be performed I declare that what I
claim is :-
In vessels of the class set forth a fluid-tight cover composed of soft metal and
having in conjunction with it a wire by which when required the metal is torn
substantially as described with reference to the drawings annexed.
