I, MAYE BLANCHARD MARTIN of Melbury Lodge, Kingston Hill, in the County of
Surrey, Gentlewoman 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 relates to hot water bottles, as at present manufactured in india
rubber or similar flexible & watertight material and consists in improvements,
whereby the exit for the air from the interior of the bottle is provided at the highest
point of the bottle, and by an egress quite distinct and apart from the mouth-piece
by which the hot water is introduced, thus preventing conflict between the issuing air,
and the entering hot water, and avoiding the tendency for the boiling water to splash
over the hands of the person filling the said bottle.
And in order that my invention may be the better understood I now proceed to
describe the same reference being had to the drawings hereto annexed and to the
letters and figures marked thereon.
Fig. 1 is an outside view of my improved bottle.
Fig. 2 is a top plan of the same.
Fig. 3 is an enlarged section of the air exit, and, Fig. 4 is a plan of the same.
A is the usual india-rubber bag forming the well known hot water bottle, with
the usual nozzle a screwed cap 6 attached for safety by flexible connection to the
nozzle a and external surrounding india rubber funnel B, for filling the same with
boiling water. I prefer in my improved bottle that this screw stopper and funnel
should be placed at one corner of the bag or bottle rather than at the centre and with
the handle C in the centre.
At the other corner I provide an air exit nozzle D, which may be fixed in any way
into the thickened corners of the bag, but, as a convenient mode of fixing, I provide
two wings d d upon the air exit nozzle, which can be embedded and secured into the
thickened edges of the india-rubber bag.
I close this air exit nozzle by a screwed cap E attached for safety by a flexible
connection to the nozzle D with a washer therein, bedding down upon the top of the
nozzle D to make an air tight joint.
To prevent loss of the cap E I attach the same by a chain or other flexible
connection to the nozzle D.
When it is desired to fill the hot water bottle or bag, both screw caps 6 & E from
the water admission and air exit, nozzles are removed and the water being admitted
by the nozzle a the air can escape from the nozzle D without conflict with the entering
stream of water, and thus without danger of the boiling water being splashed over
the bands of the person filling the bottle.
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 1
claim is :
The combination with an india-rubber hot water bag or bottle of an air escape
nozzle, closed by a screwed cap and placed at the highest part of the bag or bottle

page_text: and at a point apart and distinct from the water-filling entrance-nozzle, substantially
as described.
Dated this 29th day of March 1897.
