COMPLETE SPECIFICATION.
Improvements in connection with Feeding Bottles.
AUGUSTUS ALEXANDER DAVIDSON Victoria British Columbia, Canada,
Jeweller, 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:-
This invention is an improved device to be used on the rubber tubes of feeding
bottles, and through which the tubes are inserted.
The device is worked in the following manner.
When the slide is moved forward
to the first cross-cut in the tongue the flow of food through the tube will be diminished
about one-half; when it is moved to the second cross-cut the flow will be diminished
to about one-quarter of the original quantity, and the slide is moved still further
forward to shut off the supply of food entirely, or to prevent the absorption of air-
into the child's stomach if the bottle is empty of food. Heretofore the practice
has been to tie a knot in the rubber tube to shut off the supply of food, and also to
prevent the absorption of air, but this course was inconvenient and unsatisfactory,
as suction could not thereby be entirely prevented, unless the knot was made.
very tight.
The object of my invention is to remedy this defect by providing a device by
which the rubber tube is pressed together, and thereby preventing any food or air
to pass through; and this device can also be readily adjusted to regulate the flow
of food to any desired quantity.
In the drawings forming part of this Specification;
Fig. 1 is a detailed view in perspective of the device.
Fig. 2 is a perspective view of the cylinder.
Fig. 3 is a perspective view of the tongue.
Fig. 4 is a perspective view of the slide.
Fig. 5 is a perspective view of the forward ferrule.
Fig. 6 is a perspective view of the rear ferrule.
The cylinder A is open at both ends, and has the opening L along the top for the
tongue to work in.
The slide B is a domed band or ferrule which moves freely back and forth on the
cylinder A.
The tongue C is flat underneath and round on top; the hole H goes through one
end of it from side to side, and when this is connected to the rear ferrule D by the
rivet F a joint is formed upon which the tongue works up and down through the
opening L; the opposite end is bent in the form of an elbow, so that it will press
upon the rubber tube when the slide B is moved forward; K and K are two cross-
cuts in the top of the tongue C which bold the slide B in place when moved to either
of these points in order to diminish the flow of food.
The forward ferrule E and the rear ferrule D fit tightly over the cylinder A
and are securely fastened to it.
Having now described the construction, operation and advantages of my inven-
tion, what I claim and desire to secure by Patent is,
An improved device to be attached to the rubber tubes of feeding bottles for
