Improvements in Feeding Bottles.
I, RICHARD TURCK, Manufacturer, of Lüdenscheid, Germany, 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:-
In feeding bottles for infants, as usually made, the upper part of the suction tube
is of tin or india-rubber, which materials cannot be easily cleaned, thus affording an
opportunity for the deposit of microbes.
The present invention has for its principal object, to construct the feeding bottle
in such a manner, that the milk will come in contact with glass only.
In the accompanying drawings,
Fig. 1 shows a feeding bottle partly in vertical section and partly in elevation.
Fig. 2 is a separate view of the suction tube.
Fig. 3 is a vertical section of the mouth piece or cap.
Fig. 4 a horizontal section of the same.
The suction tube of glass is made in two lengths, joined together outside the
bottle, so that the milk will not touch the outside of the joint, and the tube may be
easily cleaned.
I connect the two tubes (or the two lengths of the suction tube) by making one
end slightly funnel shaped and the other slightly conical, and introducing the latter
into the former. The two ends are surrounded by a muff m, which is provided at
the top with an internal screw thread, into which fits a screw-threaded sleeve m' or
collar fixed to the upper half of the tube.
The lower half of the tube has a collar r, with which it rests in the muff m. A
pair of leather packing rings 1, 1, one above and one below the collar r, serve to
make the joint tight. By screwing the collar m¹ into the muff the two halves
m,
of the suction tube may be pressed together more or less. The upper half of the
tube is sheathed or coated with tin or other metal protecting it from the outside, so
as to become almost unbreakable. This sheathing or envelope has slots s, through
which a person may observe, whether the milk is passing through the tube. The
muff m is connected with a corkstopper or with a capsule in any convenient manner.
The drawing shows a cork stopper. The latter may be screwed on to the sleeve
which extends downward from the muff m.
If the capsule is used, a disc of glass or other unalterable material may be laid
into the same, to ensure, that the milk is exclusively in contact with glass and does
not touch metal at any part.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In feeding bottles, a suction tube composed of two halves or lengths of which
the upper half projecting over the bottle is sheathed or coated with tin or other
suitable protective metal, provided with slots, substantially as described and for
the purposes specified.
2. In a feeding bottle having a suction tube composed of two halves or lengths,
the means of connecting the said halves and forming a tight joint, one tube end
being introduced into the other and the joint surrounded with a muff or cap m which

the two halves together, substantially as described.
