PROVISIONAL SPECIFICATION.
Improvements in Infants' Feeding Bottles.
I, EDOUARD ROBERT, of 50, Boulevard de Renilly, Paris in the Republic of.
France, do hereby declare the nature of this invention to be as follows:-
This invention is applicable to feeding bottles of all descriptions and mainly
consists of a filtering arrangement, though it also comprises a special type of bottle
fitted with the filter in question, to be known as "Robert's filtering milk bottle."
In feeding bottles as constructed hitherto the liquid contents thereof are
conveyed to the mouth of the child direct so that any insects, microbes, vibrios,
animalcules, etc. etc. which may be contained in the milk are absorbed by the
child..
In order to prevent this I propose to filter the milk by placing between the
mouthpiece and the space or chamber containing the milk a disc shaped filter of
cotton fabric, felt or other porous or filtering material so that the milk before
reaching the child's mouth is sucked through such filter.
One form of feeding bottle consists of a bottle, a filter and a tube. The filter
consists of a piece of any suitable filtering material pasted or otherwise secured
between two rings of any convenient material such as bone, ivory etc. the whole
forming a plate or disc which is fitted into a hollow piece which may be termed
the "filter-case or "holder" and to which are fixed both the mouth-piece and a
flexible tube of india-rubber or the like. The opposite end of this flexible tube
fits into the glass tube passing through the stopper or cork.
"
Another form of bottle is somewhat curved and flattened and similar to that of a
fish. The flexible tube and also the filter case are here omitted. The bottle is
closed by a hollow stopper of ivory, wood etc. flexible to a certain extent and
provided in its upper part with a circular groove into which the filter is inserted
while at its top it carries the india-rubber or other mouth-piece.
A further modification is also of a flattened fish-like shape similar to that of the.
form of bottle just referred to except that the stopper is here dispensed with the
filter being directly located in an annular groove provided within the neck of
the bottle and surmounted by the mouthpiece of india-rubber or the like.

COMPLETE SPECIFICATION.
Improvements in Infants' Feeding Bottles.
I, EDOUARD ROBERT, of 50 Boulevard de Renilly, Paris in the Republic of
France, 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 is applicable to feeding bottles of all descriptions, and mainly
consists of a filtering arrangement, though it also comprises a special type of bottle
fitted with the filter in question, to be known as "Robert's filtering milk bottle."
In feeding bottles as constructed hitherto the liquid contents thereof are
conveyed to the mouth of the child direct, so that any insects, microbes, vibrios,
animalculæ, etc., etc. which may be contained in the milk are absorbed by the
child.

page_text: In order to prevent this I propose to filter the milk, by placing between the
mouthpiece and the space or chamber containing the milk a disc shaped filter of
cotton-fabric, felt or other porous or filtering material so that the milk before
reaching the child's mouth is sucked through such filter.
In the accompanying drawings are represented specimens of three different forms 5
of bottles thus provided with filters, and also the details of certain detached parts,
the combination of which constitutes my invention.
One form of feeding-bottle, represented in Figure 1, consists of a bottle, a filter,
and a tube. The filter consists of a piece of any suitable filtering material pasted
or otherwise secured between two rings of any convenient material such as bone,
ivory, etc., the whole forming a plate or disc B which is fitted into a hollow piece A
which may be termed the "filter-case or "holder," and to which are fixed both
the mouthpiece C and a flexible tube of india-rubber or the like. The opposite
end of this flexible tube fits into the glass tube passing through the stopper or
cork D.
"
Figure 2 illustrates another form of bottle somewhat curved and flattened and
similar to that of a fish. The flexible tube and also the filter-case are here
omitted. The bottle is closed by a hollow stopper A of ivory, wood etc. flexible to
a certain extent, and provided in its upper part with a circular groove into which
the filter B is inserted while at its top it carries the indiarubber or other mouth-
piece C.
A further modification is shown in Fig. 3. This bottle is of a flattened fish-like
shape similar to that of the form of bottle just referred to except that the stopper
is here dispensed with the filter being directly located in an annular groove
provided within the neck of the bottle and surmounted by the mouthpiece of india-
rubber or the like.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is
1. The employment in a feeding bottle of a filter between the contents of the
bottle and the mouthpiece substantially as described.
2. The combination with the stopper of a feeding bottle of a filter substantially
as described.
3. The combined feeding bottle stopper mouthpiece and filter substantially as
described and illustrated in Figure 1 of the accompanying drawings.
4. The combined feeding bottle stopper moutlipiece and filter substantially as
described and illustrated in Figure 2 of the accompanying drawings.
5. The combined feeding bottle stopper mouthpiece and filter substantially as
described and illustrated in Figure 3 of the accompanying drawings.
Dated this 23rd day of April 1891.
