PROVISIONAL SPECIFICATION.
Improvements in Waterproof Hot Water Bottles and the like Liquid
Receptacles.
I, JAMES HEBBLEWAITE, of Palmerston Street, Ancoats, Manchester, Secretary
and Manager of the Ancoats Vale Rubber Co., Ld., do hereby declare the nature
of this invention to be as follows:-
The improvements relate to waterproof hot water bottles, and the like liquid
receptacles; which are for the most part composed of india rubber, or india-rubber
compounds, or woven fabrics coated with such substances; and have for object the
more readily and conveniently filling of the same with the water or other liquid.
Waterproof hot water bottles, and the like, are at present for the most part
inconvenient in filling with liquid for want of a proper vent for the escape of steam
and air therefrom during the operation; and mostly necessitate the use of separate
funnels or other filling apparatus provided with air vent, which apparatus is often
not available.
To accomplish the object of, and to effect my improvements, I provide in the hot
water bottle, or other like receptacle, a permanent vent, which is capable of being
opened and closed at will.
This vent may be in the form of a fine tube or opening, connecting the inside of
the receptacle with the outer air, directly through the top or side of the bottle, and
terminating in a slide or stop valve, or other controlling means for closing the
opening or the tube may be passed up, or form part of the neck or opening in the
bottle, through which the water or other liquid is passed, for filling the same.
Variations in the character of the tube or opening forming the vent may be made,
together with the position thereof, and the construction of the valve, or closing
means, or apparatus therefor, without departing from the peculiar character of the
invention.

COMPLETE SPECIFICATION.
Improvements in Waterproof Hot Water Bottles and the like Liquid
Receptacles.
I, JAMES HEBBLEWAITE, of Palmerston Street, Ancoats, Manchester, Secretary
and Manager of the Ancoats Vale Rubber Co., Ld., 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 :-
The improvements relate to waterproof hot water bottles, and the like liquid
receptacles, which are for the most part composed of india-rubber, or india-rubber
compounds, or woven fabrics coated with such substances, and have for object the
more readily and conveniently filling of the same with the water or other liquid.
Waterproof hot water bottles, and the like, are at present for the most part
inconvenient in filling with liquid for want of a proper vent for the escape of steam
and air therefrom during the operation, and mostly necessitate the use of separate
funnels or other filling apparatus provided with air vent which apparatus is often
not available.
To accomplish the object of, and to effect my improvements, I provide in the hot
water bottle or other like receptacle a permanent vent which is capable of being

page_text: opened and closed at will. This vent may be in the form of a fine tube or
opening, connecting the inside of the receptacle with the outer air, directly through
the top or side of the bottle, and terminating in a slide or stop valve, or other
controlling means for closing the opening; or the tube may be passed up, or form
part of, the neck or opening in the bottle through which the water or other liquid
is passed, for filling the same. But that the improvements may be better under-
stood, I will, with the aid of the accompanyings proceed more fully to describe
means employed by me.
DESCRIPTION OF DRAWINGS.
Fig. 1, shows in elevation one form of hot water bottle arranged in accordance
with my invention.
Fig. 2, shows a plan view of the same partly inflated; and
Fig. 3, shows an enlarged sectional view of one kind of valve, which I provide for
the purpose of allowing the escape of steam and air to take place during the time
the bottle is being filled.
a, a, is the india-rubber boitle body; b, b, is a funnel for facilitating the filling
of the bottle with water, and in which funnel is provided, by preference, a screwed
or other cap for closing the orifice of the water inlet of the bottle when filled.
c, c, is a separate funnel, by preference, for protecting the valve, in which
(Fig. 3,) d, d, is a cap screwed into a tube e, e, which tube, in turn, is attached to
the rubber part of the bottle by means of wire bands, or in any other suitable
manner. In this form of valve, I prefer to provide a projection on the inside of
the tube e, e, as at g, for the purpose of retaining the cap d, d, within such tube.
It will be seen that when the cap d, d, is unscrewed a trifle, the hole is un-
covered and the steam or air allowed to escape.
On the bottle being charged with water to the desired extent, the cap d, d, is
again screwed down, and the filling tube closed.
Variations in the character of the tube or opening forming the vent may be made,
together with the position thereof, and the construction of the valve, or closing
means, or apparatus therefor without departing from the peculiar character of the
invention.
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 :-
India-rubber or other waterproof water bottles, provided with a valve for the
escape of steam and air, during the operation of filling the same, for the purpose
and in manner substantially as herein shown and described.
Dated this 20th day of February 1891.
