PROVISIONAL SPECIFICATION.
[Communicated from abroad by ALESSANDRO GOlfieri, of Greco Milanese,
in the Kingdom of Italy, Physician.]
An Improved Apparatus for Drawing Milk from the Breasts of
Nurses, and also for Milking Animals.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, do hereby declare
the nature of this invention to be as follows:-
This invention relates to an apparatus for drawing milk from the breasts of
nurses and also for milking animals.
The improved apparatus constructed according to the said invention comprises a
mouth-piece which may be placed against the breast of the nurse so as to surround
the nipple; an indiarubber suction pump of known construction, which may he
replaced by any other kind of suction pump or apparatus; a pipe partly made of
indiarubber and through which the milk flows out, which is collected in a small
reservoir; a pinch cock applied to the indiarubber portion of the said pipe and
designed to obstruct the passage of the milk; and a pear-shaped indiarubber ball
which is connected by a pipe of indiarubber or other elastic material to a ring
having a double wall and arranged in the glass neck of the before-mentioned
mouth-piece so that it adapts itself against the inner periphery of the neck.
The mouth-piece being placed round the nipple of the nurse's breast and a
certain vacuum having been produced by the pump, the indiarubber ball is
alternately pressed and left to itself, thus causing alternating phases of compression
and expansion to follow each other in rapid succession for the purpose of forcing
the air or other fluid contained in the said ball during the phases of compression
into the space comprised between the two walls of the ring in the before-mentioned
neck, so that the interior wall of the ring will be forced inwards.
Owing to the succession of its contraction and expansion the interior wall of the
ring exerts upon the nipple an action similar to that exerted by the lips of a
suckling, so that the nurse's breast will be emptied of its milk without giving the
nurse any pain.
It will be understood that the said neck and ring may have various forms, for
instance they may be made conical or fusiform.
The ring may be composed of several connected parts. Instead of having a
double wall it may for example possess a quadruple wall, provided that it has an
interior space susceptible of being alternately inflated and contracted under the
action of a fluid forced by the pear-shaped indiarubber ball.
By suitably modifying its dimensions this improved apparatus may also be
employed for milking animals.

I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 relates to an, apparatus, for drawing milk from the breasts of
nurses and also for milking animals.
In the accompanying drawing
Figure 1, is an elevation partly in section of the improved apparatus.
Figure 2 is a front elevation of the nipple picce and
Figure 3 is a sectional view of the same.
The improved apparatus constructed according to the said invention comprises a
nipple piece a which may be placed against the breast of the nurse so as to surround
the nipple; an indiarubber suction pump of known construction, which may be
replaced by any other kind of suction pump or apparatus; a pipe c partly of india-
rubber and through which the milk flows out, which is collected in a small
reservoir a pincer or pinch cock which, when applied to the indiarubber
portion of the said pipe e acts as a stop valve to obstruct the passage of the milk;
and a pear-shaped indiarubber ball d which is connected at by a pipe g of india-
rubber or other elastic material to a ring e having a double wall and arranged in
the glass neck of the beforementioned nipple-piece so that it adapts itself against
the inner periphery of the neck.
The nipple-piece a being placed round the nipple of the nurse's breast and a
certain vacuum having been produced by the pump b, the indiarubber ball d'is
alternately pressed and released thus causing alternating phases of compression
and expansion to follow each other in rapid succession for the purpose of forcing
the air or other fluid contained in the said ball d during the phases of compression
into the space comprised between the two walls of the ring e in the before-mentioned
neck so that the interior wall of the ring e will be forced inwards as indicated in
dotted lines in Figures 2 and 3.
Owing to the succession of its contraction and expansion the interior wall of the
ring exerts upon the nipple an action similar to that exerted by the lips of a
suckling so that the nurse's breast will be emptied of its milk without causing her
any pain.
It will be understood that the said neck and ring e may be made of other forms
than that represented in the drawing for instance they may be made.conical or
fusiform.
The ring e may be composed of several connected parts. Instead of having a
double wall it may for instance be made with a quadruple wall, provided that it.
has an interior space susceptible of being alternately inflated and contracted under
the action of a fluid forced by the pear-shaped indiarubber ball d.
By suitably modifying its dimensions this improved apparatus may also be
employed for milking animals.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is :-
1st. An apparatus for drawing milk from the breasts of nurses and for milking
animals characterized by the employment of an inflatable ring or the like e arranged

page_text: in the nippie-piece a and having a multiple or other suitably shaped wall which
under the action of a fluid such as a liquid or gas, forced alternately into its
interior space exerts, in combination with the suction pump ba sucking or drawing
action upon the nipple.
2nd. The improved apparatus constructed arranged and operating substantially
as above set forth with reference to the drawing and for the purposes specified.
Dated this 18th day of February 1895.
