my Invention of "AN IMPROVED INSTRUMENT. FOR DRAWING OFF THE MILK FROM,
THE BREASTS OF WOMEN, AND FOR- RAISING AND PROTECTING THE NIPPLE BOTH
BEFORE AND AFTER CHILD-BIRTH;" in which said Letters Patent is contained

page_text: a proviso, that I, the said Pierre Louis Thimoté Thiers, shall cause a par-
ticular description of the nature of my said Invention, and in what manner
the same is to be performed, by an instrument in writing under my hand and
seal, to be inrolled in Her said Majesty's High Court of Chancery within
six calendar months next and immediately after the date of the said in part
recited Letters Patent, as in and by the same, reference being thereunto had,
will more fully and at largo appear.
NOW KNOW YE, that in compliance with the said proviso, J, the said
Pierre Louis Thimoté Thiers, do hereby declare that the nature of my said
Invention, and the manner in which the same is to be performed, are fully
described and ascertained in and by the following statement thereof, reference
being had to the Drawings hereunto annexed, and to the figures and letters
marked thereon, that is to say:-
Figure 1 shews the entire apparatus, and the manner in which it is to bo
applied, as also the various operations of its several parts. The bell or cup A
should be put upon the breast, from which the milk is to be drawn out by
means of the pump B, which is placed at the extremity of the elastic tube C;
the milk which comes out from the breast falls into the reservoir D, from
whence, on pressing the riser of the valve E, E, it passes into the reservoir F.
When the pressure on the riser is discontinued, the valve, by means of a
spring placed underneath, closes upon the hole by which the milk escapes.
The milk having thus descended into the lower vessel or reservoir, is sucked
in by the child by means of a nipple G, placed at the upper extremity of the
tube or syphon H, which is made of india-rubber or other suitable material,
and this tube or syphon is introduced into the vessel across another tube I of
tin, soldered to one of the rings which serve to unite the reservoirs or vessels;
this tin tube supports the clastic tube, without, however, hindering its move-
ments in the slightest degree. To the lower extremity of this pliant tube,
which enters into the vessel, there is attached another tube J made of fine tin,
which by its weight remains always at the bottom, by aid of which the child is
enabled to suck out the liquid contained in the lower vessel to the very last
drop. Whilst the child is sucking in the milk already drawn out, a fresh
supply, according to its wants, may be extracted. At the extremities K, K,
of the tube J and the nipple G, there is a little ball which enters closely into
the india-rubber tube, which yields, and then immediately closes on it, by
which means the three pieces are firmly rivetted, but can, by drawing them
apart, be easily separated. The two vessels or reservoirs are rivetted by
means of two hooks soldered to the upper ring M, which fasten into an

page_text: indented ring N, attached to the lower vessel or reservoir,.and in which two
notches O, O, are made; to facilitate the movement of the hooks behind the
ring, a little bolt P, which maintains its position by means of a groove in the
upper ring, fastens into one of the notches in the lower vessel or reservoir,
which prevents the vessels from turning when they are fastened together; in
order to separate the two vessels, the little bolt is drawn back with the nail,
and the lower vessel is turned round until the notches come in contact with
the hooks, and the hooks are unfastened. The tube I may be soldered either
to the upper or the lower ring, as may be preferred.
Figure 2 shows the lower vessel or reservoir with the tube or syphon
inserted in it, which is used for the conveyance of the milk to the child. It
should be noted that in this apparatus there are two vessels, which are either
dependant upon or independant of each other, according to the manner in
which they are employed; the upper vessel is that which is used for the
extraction of the milk, the other is merely in sucking bottle appended to it,
which sucking bottle is so constructed that any aliment which can be taken in
by suction may be administered by means of it to infants. It may be made
of any form and of any size that may be desired. The principle of this
sucking bottle, and that in which the merit of the Invention consists, is the
facility with which children can make use of it by means of the flexible tube,
which yields to their movements, an effect admirably suited to their state, as it
prevents their being either annoyed or hurt, as they are liable to be in the use
of bottles which are made without this flexible tube.
Figure 3 shews the most commodious and most pleasing form in which this
apparatus may be made; the sides being hollowed, it can be more easily held,
and the hand being placed right over the liquid will help to maintain its
degree of warmth for a longer time than it would otherwise have done.
A stopper of cork, perforated, is screwed into the tin tube, which passes across
the cork of the bottle, so that the smaller cork stops up the hole of the larger
one, and prevents the liquid from escaping when the vessel is moved in an
inclined position.
Figure 4 is a more simple form of the apparatus, to allow of its being made
and sold at a cheaper rate. The manner of using it differs in this respect,
that after the milk is drawn, the apparatus should be removed from the breast,
and there should be then introduced, through the hole of the bell or cup.
a tube having the same advantages as the tubes which have been already
described, namely, partly composed of tin and partly of india-rubber, with
a nipple attached to the upper extremity of the india-rubber part of the tube,
and which two parts of the tube can, as before described, be united, so as to

page_text: against the breast, which produces a movement in the flesh; so that each blow
of the piston extracts the milk, and suffers the flesh.ito recede; thereby
avoiding the pressure, and consequently preventing iobstruction and pain; so
that the vacuum operated upon by the-drawing up. of.the.piston: is rsoon.ifilled
with a fresh-quantity of liquid, which is speedily drawn-out;by the quickly
repeated movements of the piston, very nearly the same effect might be
obtained, if there were not any valve to the pump, but too great a quantity
of air would enter into the vessel, which would cause too:great:a. resistance,
and inflict a blow, by forcing the air- to. pass between the.bell.or..cup. and
the skin. I mention this method to guard against counterfeites, but most
assuredly the method above described is preferable to all others, and produces
the most beneficial effects, as I have ascertained by repeated experiments.
T shows the form of the screw'inverted in the pump, and to which the valve is
attached; the pump screws on to a nozzle fixed to the tube, and may be taken
off at pleasure; a ring made of leather is placed between 'the "screw and the
nozzle to prevent the air from passing.
In witness whereof, I, the said Pierro Louis Thimoté Thiers, have
hereunto set my hand and seal, this Fifth day of July, in the year
of our Lord.One.thousand.cight:hundred and forty-seven.
