AN IMPROVED CAP FOR FEEDING OB OTHER BOTTLES
Year: 1875

page_text: LETTERS PATENT to Henry Burton Pare, of Bolton, in the County
of Lancaster, for the Invention of "AN IMPROVED CAP FOR FEEDING OB
OTHER BOTTLES."
Scaled the 13th August 1875, and dated the 4th March 1875.
PROVISIONAL SPECIFICATION left by the said Henry Burton Parc at
the Office of the Commissioners of Patents, with his Petition, on
the 4th March 1875.
I, HENRY BURTON PARE, of Bolton, in the County of Lancaster, do
hereby declare the nature of the said Invention for "AN Improved Cap
FOR FEEDING OR OTHER BOTTLES," to be as follows :-
This Invention is designed principally to be applied to such infants'
feeding bottles as are provided with an elastic tube, and is intended to
be used as a substitute for the earthenware cap and cork usually
employed to close the mouth of the bottle and carry the tube.
For this purpose I make a cap of pure india-rubber to fit over the neck
of the bottle. The mouth of this cap is made rather smaller than the neck

page_text: of the bottle and the interior of the cap, so that when the cap is forced
over the neck of the bottle the mouth of the cap when expanded, and
in contracting again by its own elasticity, it will hold firmly on to the
neck.
In the centre of the cap (which is made rather thicker than the body
of the cap) I form a cylindrical hole to fit the glass syphon pipe to
which the elastic tube is connected, and at one side of this hole I form a
narrow opening for the admission of air into the bottle to take the place
of the milk or other contents withdrawn therefrom.
It will be evident that a cap of this kind, cither with or without the 1
hole in the top, may also be used with advantage for closing the mouths
of other kinds of hottles
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Burton Parc in the Great Seal Patent Offico
on the 28th August 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
BURTON PARE, of Bolton, in the County of Lancaster, send grecting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of March, in the year of
our Lord One thousand eight hundred and seventy-five, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Henry Burton Parc, Her special license
that I, the said Henry Burton Pare, my executors, administrators, and
assigns, or such others as I, the said Henry Burton Parc, my executors,
administrators, and assigns, should at any time agree with, and no
others, from time to time and at all times thereafter during the term
therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the
Channel Islands, and Isle of Man, an Invention for "AN IMPROVED CAP
FOR FEEDING OR OTHER BOTTLES," upon the condition (amongst others) that
I, the said Henry Burton Parc, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and
scals, should particularly describe and ascertain the nature of the said

page_text: Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Henry Burton Parc, do hereby
declare the nature of the said Invention, and in what manner tho samo
is to be performed, to be particularly described and ascertained in and
by the following statement and accompanying Drawing:-
This Invention is designed principally to be applied to such infants'
feeding bottles as are provided with an elastic tube, and is intended to
be used as a substitute for the earthenware caps or corks as usually
employed to close the mouth of the bottle and carry the tube..
Such being the nature and object of my said Invention I will now
proceed to describe in detail the manner in which the same is to be or
may be performed or carried into practical effect; and in order that
the same may be clearly understood I have annexed hereunto a
Sheet of Drawings illustrative thereof, and have marked the same with
figures and letters of reference corresponding with those in the following
explanation thereof:-
Fig. 1 shows a partial section of a feeding bottle to which is applied
one of my improved caps made without a central plug to fit inside tho
neck, and Fig. 2 shows the same with a central plug; Fig. 3 is a section
of a cap shown at Fig. 2 when removed from the bottle.
I make a cap a, a, of pure india-rubber, with a rim b, b, to fit over the
neck of the bottle, and either with or without a central plug c, c, to fit
inside the neck of the same.. The mouth of the rim b, b, is made rather
smaller than the neck of the bottle and the interior of the cap, as
clearly seen in the detached section, Fig. 3, so that when the cap is
forced over the neck of the bottle the mouth of the cap will be expanded,
and in contracting again by its own elasticity it will hold firmly on to
the neck.
In the centre of the cap (which should be made rather thicker than
the body) I fix a short tube or cylinder d, d, of metal, ivory, or bone, in
which fits the elastic tube e, e, and at one side of this tube I form a
narrow opening at ** for the admission of air into the bottle to take the
place of the milk or her contents withdrawn therefrom.

page_text: It will be evident that a cap of this kind, either with or without the
hole in the top, and either with or without the central plug, may be used
with advantage for closing the mouths of other kinds of bottles.
Having now described the nature and object of my said Invention,
together with the manner in which the same is to be or may be per-
formed or carried into practical effect, I wish it to be understood that I
claim as my Invention, the improved form and construction of cap for
feeding or other bottles, as herein-before described and illustrated by the
Drawings annexed.
In witness whereof, I, the said Henry Burton Parc, have hereunto:
set my hand and seal, this Twenty-fourth day of August, in
the year of our Lord One thousand eight hundred and seventy-
five
HENRY BURTON PARE. (L.S.)
