AN IMPROVED FEEDING BOTTLE
Year: 1858

page_text: LETTERS PATENT to James Knott, of No. 63, Oakley Street, Lambeth,
in the County of Surrey, Glass Manufacturer, for the Invention of "AN
IMPROVED FEEDING BOTTLE."
Sealed the 20th August 1858, and dated the 27th February 1858.
PROVISIONAL. SPECIFICATION left by the said James Knott at the
Office of the Commissioners of. Patents, with his Petition, on the
27th February 1858..
I, JAMES KNOTT, of 63, Oakley Street, Lambeth, in the County of Surrey,
Glass Manufacturer, do hereby declare the nature of the said Invention for.
"AN IMPROVED FEEDING BOTTLE," to be as follows:--
I make the bottle much wider at the bottom part than the top, the latter.
being about the proper size to put into the mouth; if used for adults it may be
a little larger than for infants, the said top or mouth part being bent a little
in the direction of the hole for supplying the bottle with the requisite liquid..
I place the supply hole near the bottom part of the bottle, and in a line with
the curved end, so that the person feeding the infant or invalid, can regulate.
the quantity of liquid to be administered by placing the thumb over the hole,.
and admitting air as required, to increase or diminish the flow to the mouth.
I fix a valve on this hole, when desired to regulate the flow of the liquid.
It will be observed, that by turning or bending the mouth part of the bottle,.
it is more convenient for feeding, and also prevents the liquid running out

hole.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Knott in the Great Seal Patent Office on the 26th
August 1858.
:
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
KNOTT, of No. 63, Oakley Street, Lambeth, in the County of Surrey, Glass
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-seventh day of February, in the year of our
Lord One thousand eight hundred and fifty-eight, in the twenty-first year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said James Knott, Her special licence that I, the said James Knott,
my executors, administrators, and assigns, or such others as I, the said
James Knott, 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 IM-
PROVED FEEDING BOTTLE," upon the condition (amongst others) that I, the said
James Knott, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said 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 James Knott, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement (that is to say) :-
I make my improved feeding bottle (which is suitable for either infants or
invalids) of a peculiar shape or construction, with the hole or inlet at the upper
side, and near the end, by which arrangement it can be filled and laid aside

page_text: without the possibility of any portion of its contents running out; and I make
the cork or stopper for the inlet hole to form or act as a valve, and admit of
sufficient air to allow the food or medicine to be drawn off by suction, without
allowing the air to mix or incorporate with the contents; it also allows the
bottle, when filled, to be immersed in warm water, to keep the food warm,
which is very desirable when used for feeding infants.
The said stopper valve may be made of wood, metal, india-rubber, or any
suitable material.
These improvements will be clearly understood by reference to the accom-
panying Sheet of Drawings, and the figures & letters of reference thereon.
Fig 1 & 2 are views of my improved feeder, and Fig 3, a section of the
valve stopper.
The said stopper consists of a knob or part a, having a recess, into which is
screwed the part b, furnished with cork or other tightening material c, both
parts having holes d for the admission of air. Within the recess is a disc or
valve e of caouchouc, or other material of an elastic and closing nature, the
said valve having one ore more holes, so that when suction is applied to the
teat or nipple f, air enters the bottle and causes the flow of the liquid; but
when there is no suction, the elasticity of the material closes the hole in the
disc, and also the hole in the knob, and thereby prevents the admission of air.
On the mouth of the taper neck of the feeder I fix a teat, made of any
suitable elastic material with very small perforations, to allow the liquid to
pass, and, if necessary, I fix a strainer to the nipple of the bottle, made of fine
wire or other suitable material, to prevent the smallest particles of hard food
being conveyed to the stomach. It is evident that my improved feeder may
be advantageously used to administer medicine to cattle, but in such case it
may be made of tin, gutta percha, or other cheaper and more substantial sub-
stance then glass.
Having thus fully discribed the nature of my said Invention, and the
manner in which the same is to be performed, I desire it to be distinctly
understood that I do not confine myself to any particular dimensions of the
bottle or feeder, nor to the precise construction of the valve stopper; but I
claim as my Invention, and which, to the best of my knowledge and belief, has
not been hitherto used within the realm,-
Firstly, the shape and configuration of a bottle or feeder with two flat sides
and taper neck, and the inlet hole at the upper side, so that when the vessel is
filled and laid aside, no portion of its contents can run out.
And, secondly, the improved stopper valve, for regulating the supply of air

page_text: for the flow of the liquid by suction, as such improvements are herein described
and illustrated in the accompanying Sheet of Drawings.
In witness whereof, I, the said James Knott, have, hereunto set my hand
and seal, this Twenty-sixth day of August, in the year of our Lord One
thousand eight hundred and fifty-eight.
JAMES KNOTT.. (L.S.)
Signed, sealed, and delivered, by the
within-named James Knott, in the
presence of
