IMPROVEMENTS IN FEEDING BOTTLES
Year: 1883

page_text: PROVISIONAL SPECIFICATION left by the said Edward Brasier at the
Office of the Commissioners of Patents on the 27th June 1883.
EDWARD BRASIER of Bastable House New Cross in the County of Surrey,
Engineer, " IMPROVEMENTS IN FEEDING BOTTLES"
This invention relates to improvements in feeding bottles such as are used for
feeding infants and the object of my improvements is to prevent the suction of air
when the fluid contents have been drawn out of the feeding bottle or vessel
For this purpose I apply an improved valve to the lower end of the flexible or
other pipe to which the nipple is attached. This valve is so arranged that the
cover which closes the inlet to the suction pipe floats or riscs above the inlet whilst
there is any milk or fluid in the bottle but sinks or falls over the inlet passage or
passages directly the fluid is exhausted thus closing the valve and preventing air
from being sucked up up through it.

This Invention relates to improvements in feeding bottles such as are used for
feeding infants and the object of my improvements is to prevent the suction of air
when the fluid contents have been drawn out of the feeding bottle or vessel.
For this purpose I apply an improved valve to the lower end of the flexible or
other suction pipe to which the nipple is attached. This valve is so arranged that
the cover which closes the inlet to the suction pipe floats or rises above the inlet
whilst there is any milk or fluid in the bottle but sinks or falls over the inlet
passage or passages directly the fluid is exhausted thus closing the valve and
preventing air from being sucked up through it.
Figure 1 shows a sido view with the floating suction valve a closed. Figure 2 a
view of the flat side of the bottle with the floating suction valve a open. Figure 3
shows a section with the valve a closed and Figuro 4 a side view of the valve a
open these Figures being drawn on an enlarged scale. Figure 5 shows another
form of floating valvo a the valve in this arrangement being jointed at a¹ to the
suction tube b.
In Figures 3 and 4 the valve a rises and falls on the lower end of the suction
tube 6 to open or close the passages b¹ in the end of the suction tube b.
A ball valve 62 may be used in combination with my improved floating valve if
desired and as represented in Figure 3.
The feeding bottle is formed according to my improvements with a well at the
bottom for the valve a to fall into to ensure the whole of the contents being
drawn out.
Having thus described the nature of my invention and the manner of carrying
the same into practice I make no claim to any of the parts separately which are
well known and in common use, But, what I claim is:-
The improved arrangement and construction of feeding bottles by the application
of a floating valve thereto so arranged that the cover a which closes the inlet to
the suction pipe b floats or rises above the inlet whilst there is any milk or fluid
in the bottle (which is formed with a well as shown) and passes over the inlet
passage or passages directly the fluid is exhausted thus closing the valvo, and
preventing air from being sucked up through it the whole being arranged to act
substantially in the manner and for the purpose herein before described and
represented in the drawings annexed.
In witness whoreof I the said Edward Brasier have hereunto sot my hand and
seal this Twenty fourth day of Decomber in the year of our Lord One thousand
eight hundred and eighty three.
