Boston, Suffolk County, State of Massachusetts, one of the United States of
America, Manager of Rubber Works.
I ALFRED GEORGE BROOKES of the firm of Wm. Brookes & Son of 55 & 56
Chancery Lane in the County of Middlesex, Patent Agent 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 improved nipples forming the subject of this invention are provided with an
independent enlargement or guard which is located in the body of the nipple between
its delivery end and the enlargement at the base of the nipple which fits the neck of
the bottle, the contracted or waist portion of the nipple between the said guard and
the base of the nipple constituting a free bending point for the nipple between the
base of the nipple on the neck of the bottle and the guard.
The guard is an integral part of the body of the nipple, and as shown is made hollow
whereby it is made more soft and elastic.
I have shown the nipple as made substantially round in cross section as such
shape is better adapted to a childs mouth than a nipple which is oval in cross
section.
This invention consists in an india-rubber nipple having a neck, a base, and an
independent enlargement made as a hollow ring and located between the said base
and delivery end of the nipple, to operate substantially as described.
Also in an india-rubber nipple it having a body, a base, a contracted waist, and an
independent enlargement or ring intermediate the delivery end of the nipple and the
said contracted waist; the latter constituting a free bending point between the base
which fits the neck of the bottle and the said guard.

of a bottle.

page_text: The delivery end of the nipple properly perforated is located at the end of a short
body b which in practice will preferably be substantially circular in cross section, the
said nipple having an enlarged base as c which is applied in the usual manner to the
mouth or delivery end of the bottle or other article containing the milk, between the
base and the delivery end of the bottle.
The body 6 is provided with an enlargement d between the base c and the delivery
end of the nipple, the said enlargement d serving the purpose of a guard, the said
enlargement or guard being represented as forming a sort of hollow projecting ring, the
nipple between the base and guard being contracted to leave a waist f which constitutes
a bending point where the nipple may be bent freely between the guard and base or
bottle, and yet not stop the flow of milk.
The enlargement or guard determines the extent to which the nipple will enter the
mouth of a child, and it also forms an easy bending point outside the end of the
bottle, and between the base and that part of the body of the nipple which is held in
the mouth of the child.
Further, the elongation and contraction of the nipple as it is pulled by the child,
causes the rubber of the nipple at the enlargement, to aid in forcing or expelling
the milk.
The nipple is very flexible and in practice is made from the best of rubber.
By reason of the enlargement d, the efficient area of the passage through the
nipple as measured in the neck proper b, is not contracted when the nipple is bent
partially over, and when in the mouth of a child.
By making the enlargement or guard hollow as shown, the nipple is made to bend
easily at that point which will be just outside the mouth of the child, and the said
hollow ring also obviates any undue contraction of the milk space when the nipple
is bent.
my
Having now particularly described and ascertained the nature of said
Invention, and in what manner the same is to be performed, I declare that what
I claim is :
1. An india-rubber nipple having a neck, a base, and an independent enlargement
made as a hollow ring and located between the said base and delivery end of the nipple,
to operate substantially as described.
2. The Lerein described india-rubber nipple, it having a body as b, a base c, a
contracted waist f, and an independent enlargement or ring intermediate the delivery
end of the nipple and the contracted waist, the said waist constituting a free bending
point between the base c, which fits the neck of the bottle and the said guard,
substantially as described.
3. The manufacture and use of nipples for nursing bottles as and for the purpose
set forth.
