PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of India Rubber Waterbottles,
Beds, Pads, and other like Vessels.
I, THEODORE BIRNBAUM Wick Lane Rubber Works Bow, London, E. do
hereby declare the nature of this invention to be as follows:-
I form the inner lining and funnel of the bottle of pure sheet rubber which
is then steam vulcanised. I next apply to the vulcanised body an india rubber
coated fabric, preferably melton, flannel, felt or other suitable material, which has
been previously coated on one side with a dry heat vulcanising dough; this covering
I cause to thoroughly adhere to the rubber lining and the two are then vulcanised
together in a chamber by the process known as dry heat. The cloth flanges of the
vessel are then suitably bound or braided to give strength and finish.
By the herein before described process I produce a waterbottle, bed or pad com-
posed of an inner lining of vulcanised rubber which is vulcanised to an outer lining
of any suitable fabric and I claim that the article is softer, lighter, and more durable
than bottles produced by other means.
That it retains the heat for a longer period and is more comfortable and beneficial
to the user.
That it cannot readily leak or get out of repair.
That any defect can be readily ascertained and repaired when necessary.
THEODORE BIRNBAUM.

THEODORE BIRNBAUM Wick Lane Rubber Works, Bow, E. India Rubber
Manufacturer 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 :-

"
I form the inner lining and funnel of the bottle of pure sheet rubber, which is
then steam vulcanised. I next apply to the vulcanised body an india rubber
coated fabric preferably melton flannel, or it may be felt or other suitable material,
which has been previously coated on one side with a dry heat vulcanising dough ;'
this covering I cause to thoroughly adhere to the rubber lining by suitable means
and the two are then vulcanised together in a chamber by a process known as "dry
heat." The cloth flanges or edges of the vessel are then suitably bound or braided
to give strength and finish.
By the hereinbefore described construction or process of manufacture I produce
a waterbottle, bed, or pad or other vessel composed of an inner lining of vulcanised
rubber which is vulcanised to an outer lining of any suitable fabric in the manner
described.
I claim for my improved waterbottle, bed pad or other similarly constructed
india rubber vessel, the following amongst other advantages, viz. :-
That such a waterbottle, or vessel, of pure rubber vulcanised to a suitable cloth
or other covering enables repairs to be easily and effectually made thereto in case
of injury or leakage all parts being readily accessible.
That such a bottle or vessel is lighter and more durable than bottles or vessels
produced by other means in ordinary use.

page_text: That such a vessel will retain heat for a longer period, and is more comfortable
and beneficial to the user than those of ordinary manufacture.
That the vessel cannot readily leak or get out of order.
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 :-
covering
The improved construction and manufacture of a waterbottle, bed, pad or other
like vessel, of india rubber, steam vulcanised and then cemented to a
fabric of suitable character and the whole finally subjected to dry heat vulcanisation,
all substantially as and for the purpose set forth.
Dated the 22nd day of November 1892.
