IMPROVEMENTS IN OR APPERTAINING TO FEEDING BOTTLES FOR BABIES "
Year: 1883

page_text: LETTERS PATENT to Alexander Horne and John Mancor both of Liverpool
in the county of Lancaster for an Invention of "IMPROVEMENTS IN OR
APPERTAINING TO FEEDING BOTTLES FOR BABIES
"
PROVISIONAL SPECIFICATION left by the said Alexander Horne and
John Mancor at the Office of the Commissioners of Patents on the 22nd May
1883.
ALEXANDER HORNE. and JOHN MANCOR both of Liverpool in the county of
Lancaster "IMPROVEMENTS IN OR APPERTAINING TO FEEDING BOTTLES FOR
BABIES
"
In ordinary feeding bottles there is, only one passage for the admission of air and
the exit of food. The consequence is as the child sucks, a partial vacuum is formed
in the bottle, causing the soft lips of the child to be drawn into the feed orifice, and
the cork has to be extracted from time to time to admit air.
Now our invention is designed to admit the air simultaneously with the
extraction of fluid.
·
+
For this purpose, we form the stopper with a valve or valves and air passages.
The stopper, can be of earthenware, wood, glass, or other suitable material. Through
this we pass the tube in the ordinary manner. We however pierce the stopper
with one, two, or more independent holes from the outside air to the interior of the
bottle, and the inner orifices of these holes we cover with a rubber or other valve.
This can be done in various ways, the tube hole can be widened out to near the
bottom and small holes drilled through to the interior of the bottle from the bottom
of the widened part round the central hole. A thin india-rubber washer is then
placed over their orifices, being shrunk on a tubular projection with annular groove
on the shank of the stopper. Or, the stopper can be fitted to the bottle neck by
means of a projecting india-rubber band; and below this band the stopper can be
turned considerably smaller than the bottle neck. Holes are then bored through
the substance of the stopper into the enlarged part of the tube hole from a groove
on the outside of this turned down portion; a rubber ring shrunk on this groove
acts as a valve.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Alexander Horne and John Mancor in the Great Seal Patent
Office on the 22nd November 1883.

APPERTAINING TO FEEDING-BOTTLES
FOR
In ordinary feeding bottles there is only one passage for the admission of air and
the exit of food. The consequence is as the child sucks, a partial vacuum is formed
in the bottle causing the soft lips of the child to be drawn into the feed orifice, and
the stopper has to be extracted from time to time to admit air.
Now our invention is designed to admit the air simultaneously with the
extraction of fluid.
It is best described by aid of the accompanying drawings in which
Fig 1-is a sectional elevation of the apparatus complete.
Fig 2.-longitudinal section of stopper enlarged size.
Fig 3.-transverse section of same through x x Fig 2, and
Fig 4. enlarged end view of nozzle showing cruciform suction orifice.
A is the body of, the stopper, it can be formed of earthenware, wood, glass,
or other suitable material. Through this we pass the tube B'in the ordinary
manner. We however pierce the stopper with one, two, or more independent
holes C (three are shown in the drawing) from the outside air to the interior of the
bottle, and the inner orifices of these holes we cover with a rubber or other valve D.
This can be done in various ways, the 'tube hole can be widened out at top as
shown at E, and small holes C drilled through to the interior of the bottle from the
bottom of the widened part round the central hole. The thin india rubber washer D
is then placed over their orifices, being shrunk on the annular groove F'in the
tubular projection G of the shank of the stopper. The stopper is fitted to the
bottle neck by means of a projecting band H of india-rubber or other material. To
still further prevent all chance of leakage when the child is not feeding, we form
the nipple or nozzle with a cruciform hole in the soft rubber'formed by a cruciform
chisel, which while opening readily with the gentle suction of the child, closes
perfectly when that suction is withdrawn, thus keeping the tube 'full' of 'food,
thereby the child does not receive a quantity of air every time the teat' leaves the
mouth. This is shown in the drawing at Fig. 4.
Instead of the parts C, D, F and H described in the drawings, the following
variation can be used. Below the india-rubber band H if desirable the hard' body
of the stopper can be turned considerably smaller than the bottle neck and holes
bored through the substance of the stopper from an annular groove in this reduced
portion into the enlarged tube hole E. An india-rubber ring shrunk over the
groove in which these holes debouch, then acts as a valve. 'We have not shown
this plan in the drawings as we consider it inferior to the one shown, and merely
describe it now as it was mentioned in the provisional specification, and we do not
wish it to be understood that we throw it' open to the public.
Having now described and 'fully delineated the best mode known to us of
carrying our invention'into effect and also described an available variation, we
wish it to be understood that what we believe to be new and desire to protect
under the Letters patent is:
The manufacture of feeding bottles with stoppers so constructed that in propor-
tion as the food is sucked out of the bottle so shall air enter through a passage or

page_text: passages in the stopper to take its place, and yet the bottle shall be practically
water and air-tight when the child is not sucking.
The special arrangements and combinations of parts for feeding bottles and their
appurtenances, substantially as and for the purposes herein described.
In witness whereof we the said Alexander Horne and John Mancor have hereunto
set our hands and seals this first day of November, in the year of our Lord, one
thousand eight hundred and eighty three.
