Improvements in and relating to Feeding Bottles.
We, WILLIAM EDGAR WILLIAMS, of the Exchange, Cardiff, in the County of
Glamorgan, Colliery Proprietor, and REES RODERICK, of Pandy Cottage, Hirwain,
Aberdare in the County of Glamorgan, Colliery Manager, do hereby declare the
nature of this invention to be as follows:
Our invention relates to feeding bottles, and has for its object to allow of a
constant and uniform supply of milk or other alimentary liquid on suction by the
infant.
In feeding bottles hitherto employed no provision has been made for the ingress
of air to maintain constant pressure within the bottle, so that the flow of liquid
on consumption gradually becomes less until the cork is unscrewed or withdrawn,
for the admission of air and replaced, when the normal supply can be obtained..
My invention is designed to obviate this usual necessity, and consists in the
provision of an air tube from within the bottle around its exterior; such tube
passing preferably from within the neck, around the base of the bottle and diverted
in the opposite upward direction, passing the full length of the bottle and
terminating in an open aperture.
By the provision of such a tube there is always a free communication from the
upper interior portion of the bottle with the atmosphere, and consequently the
pressure upon the contained liquid is constant and the flow on suction uniform;
while leakage is rendered impossible.
In carrying our invention into effect we may provide our air tube extending the
length of one side of the bottle and formed integral with the glass or other material
of which the bottle is composed; or we may provide a groove upon the bottle in
the direction of its length passing round the base thereof, and place therein an
india-rubber tube secured at its extremities to nozzles provided at the upper ends
of such grooves in the substance of the glass having in the one case communication
with the interior of the bottle; the nozzle being provided at the other end merely
to keep the return branch of the tube in position.
It will therefore be observed that we do not confine ourselves to any disposition
or connection of the air tube.
Dated this 22nd day of September 1896.

page_text: Improvements-in and relating to Feeding Bottles.
We, WILLIAM EDGAR WILLIAMS, of the Exchange, Cardiff, in the County of
Glamorgan, Collier Proprietor and REES RODERICK, of Pandy Cottages, Hirwain,
in the County of Glamorgan, Colliery Manager, 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:-
Our invention relates to feeding bottles and has for its object to allow for a
constant and uniform supply of milk or other alimentary liquid on suction by the
infant.
In feeding bottles hitherto employed .no efficient provision has been made for
the ingress of air to maintain a constant pressure within the bottle so that the
flow of liquid on consumption gradually becomes less until the cork is unscrewed
or withdrawn for the admission of air and replaced.
Our invention is designed to obviate this usual necessity and is illustrated in
the accompanying drawings, in which,
Figure 1 is a sectional elevation, and
Figure 2 a front elevation corresponding thereto of a feeding bottle with our
invention applied.
Figures 3 and 4 are respectively sectional elevation and front elevation of a
nidification in which our invention is carried into effect, while
Figure 5 is a sectional elevation of a further modification.
Our invention consists in the provision of an air tube from within the bottle,
such tube passing preferably from within the neck to the base of the bottle, and
diverted in the opposite direction, passing the full length of the bottle and
terminating at the upper extremity in an open aperture, in communication with
the atmosphere. By the provision of such a tube there is a free communication
from the upper interior portion of the bottle with the atmosphere, and consequently
the pressure upon the contained liquid is constant and the flow on suction uniform.
In carrying our invention into effect as illustrated in Figures 1 and 2 of the
accompanying drawings we provide a bottle B which may he of the usual form,
and of glass, having a supply tube D reaching to the lower part of the bottle and
carried by the stopper E, a feeding tube being secured to the extremity of such
supply tube D.
Upon the exterior face of the bottle we provide a recess A for the purpose of
receiving an air tube C, preferably of glass, of U-shape, the one extremity of
which is fitted within a hole formed or provided at the upper side or wall of the
recess A by such means as a nipple G, so that communication is made from the
upper part of the interior of the bottle with the atmosphere, whereby the atmos-
pheric pressure is maintained in the interior, and the flow of the milk or alimentary
liquid is maintained uniform on suction.
It will be understood that on the down turning of the bottle the liquid would
pass up the contiguous branch of the air tube but not to a sufficient extent to
enable the liquid to pass down the other branch, while the inwardly projecting
extremity of the air tube is maintained at a sufficient height as to be normally
above the level of the milk contained therein, so that the leakage of the liquid in
any position of the bottle is precluded, while suction effects the clearance of the
air tube of any liquid that may gain access thereto.
Figures 3 and 4 show a modification in which an air tube C is passed around the
base of the bottle up on the other side, while Figure 5 shows an arrangement in

page_text: which the air tube C is secured to the stopper E and its opposite end diverted and
terminates in a position at the upper part of the interior of the bottle.
We may forni the air tube extending the length of one side of the bottle and
formed integral with the glass or other material of which the bottle is composed,
or an india-rubber tube may be provided in the groove A, as indicated in Figure 3,
passing around the base of the bottle, which tube may be secured at its upper
extremity as illustrated, or an india-rubber tube may be provided which passes
around the base of the bottle secured at its extremities to nozzles provided at the
upper ends of the grooves A in the substance of the glass, having in the one case
communication with the interior of the bottle, while in the other case the nozzle
merely serves to keep the return branch of the tube in position.
It will therefore be observed that we do not confine ourselves to any disposition
or connection of the air tube.
Having now particularly described and ascertained the nature of our said in-
vention, and in what manner the same is to be performed, we declare that what
we claim is:
1. In a feeding bottle, means for the provision of air communication to the
upper part of the interior of the bottle consisting of a U-tube, having one branch
connected and in communication with the upper part of the interior of the bottle,
while the other communicates with the atmosphere, and each branch is of a
length determined by the depth of the bottle.
2. In a feeding bottle, means for the provision of air communication to the upper
part of the interior of the bottle consisting of a U tube, one end of which is
connected and is in communication with the upper part of the interior of the
bottle, while the other is in communication with the atmosphere, such Ụ tube
being arrranged upon one side of the bottle, and of a length corresponding thereto,
substantially as described.
3. In a feeding bottle, means for the provision of air communication to the
upper part of the interior of the bottle consisting of a U tube, one branch being
connected and in communication with the upper part of the interior of the bottle,
while the other communicates with the atmosphere, such U tube passing around
the base of the bottle substantially as described.
4. In a feeding bottle, means for the provision of air communcation to the upper
part of the interior of the bottle consisting of a U-tube, one branch of which is
secured upon the stopper and in communication with the atmosphere, which branch
is of a length corresponding to the depth of the bottle and is diverted and
terminates at the upper part of the interior of the bottle substantially as described.
5. In feeding bottles the several means for the provision of air communication
to the interior thereof, substantially as and for the purpose hereinbefore described
with reference to Figures 1, 2, 3, 4, and 5 of the accompanying drawings.
6. In feeding bottles, means for the provision of air communication to the
interior thereof, substantially as described.
