PROVISIONAL SPECIFICATION.
Improvements in Feeding Bottle Interior Tubes.
JOHN NEUMAN, Chemist, 2, Edwards Villas, Southchurch Beach, Southend,
Essex, do hereby declare the nature of this invention to be as follows:-
To prevent wind being sucked up when the contents of the feeding bottle is
exhausted I propose to bend round horizontally or turn up, or in, or leave straight,
about an inch more or less of the bottom end of an interior feeding bottle tube and
to fit on to the end of this perfectly air-tight but capable of being turned easily
round, one end of a piece of rubber or other tubing, divided near the centre, but
leaving, or having a join or hinge on the top, and a float which shall also act as a
stopper fitted into the other end of the piece of rubber or other tubing, or 1 propose
to bend or turn up about an inch more or less of a glass (or other material) feeding
bottle tube and have the hole left round or pressed nearly together to form a slit,
over this I shall fit one end of a piece of rubber or other tubing having a float
which shall also act as a stopper fitted into the other end, and having a hole cut in
the side, or I propose to make the tube oval in shape, close the bottom, perforate a
hole in the side and have a floating band.

COMPLETE SPECIFICATION.
Improvements in Feeding Bottle Interior Tubes.
JOHN NEUMAN, 2, Edwards Villas, Southchurch Beach, Southend, Essex,
Chemist, 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 :-
To bend round horizontally or turn up, or in, or leave straight, about an inch
more or less of the bottom end of a glass or other material feeding bottle tube A,
and to fit on to the end of this, one end of a piece of india-rubber or other tubing b,
almost divided near the centre, but leaving or having a join or hinge, and a float
consisting of a bulb c of glass or wood or cork or other material, which shall also
act as a stopper, fitted into the other end of the aforesaid almost divided piece of
india-rubber or other tubing. Its action is that when in the bottle the said bulb c
floats up on the milk, thereby opening the cut, or almost divided part of the piece
of india-rubber or other tubing, and thus allows the liquid to be withdrawn, and
as the aforesaid bulb c floats down, it allows the aforesaid cut-part to close, and
thus prevents any wind being sucked up when the milk is withdrawn.
I consider the above form to be the best means of carrying my invention into effect,
but other means might be adopted such as the following, I propose to bend or
turn up, about an inch more or less, of a glass or other material feeding bottle tube
and have the hole left round or pressed nearly together to form a slit, over this I
shall fit one end of a piece of india-rubber or other tubing, having a float which
shall also act as a stopper fitted into the other end, and having a hole cut in the
side of the aforesaid piece of india-rubber or other tubing. In action this tube is
similar to the former, but the wind is stopped by means of a kink or bend formed in
the piece of india-rubber or other tubing, by the bulb floating down on the milk as
it is withdrawn. Or I propose to make the tube flat in shape, close up the bottom
and perforate a hole in the side over which I shall have a floating band, to close the
valve by covering the hole.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the-same-is to be performed, I declare that what I
claim is:
The employment of means to prevent any wind, or air, being sucked up, when
the liquid in the bottle is withdrawn, substantially as hereinbefore described.
Dated this the 19th day of February 1891.
