PROVISIONAL SPECIFICATION.
An Improved Method of and Device for Sterilizing Victuals,
Beverages, Remedies, and the like.
I, Dr. Med. JOSEPH BASSFREUND residing at Hildesheim, in the Province of
Hannover, Kingdom of Prussia, German Empire, Physician do hereby declare the
nature of this invention to be as follows:-
This invention relates, first, to a method of sterilizing water, milk and other
beverages; victuals, as for instance preserved fruits; further, remedies for internal
use as well as for external application, and is characterized by leading streaming
steam through, or around and through, the stuff to be sterilized, the respective stuff
being contained in a vessel that is not cooled at its outer side, but is heated, and at
the same time sterilized itself, solely by the said streaming steam.
My invention consists, further, in the construction of special vessels for carrying
my new method into effect, the said vessels being characterized by having an inlet,
an outlet, and a cover or lid that is adapted to close one of, or both, the said
openings in such a manner, that in any case the sterilized contents of the
respective vessel are prevented against re-infection, and may yet be taken out of
the vessel in portions, as necessary, for instance, for the several repasts of a little
child.
In carrying my invention into effect I take a bottle or vessel, which is provided
with an inlet and an outlet, the former having preferably a tube or pipe by means
of which the steam is led down onto the bottom of the vessel. Into the said vessel
has been put the stuff (milk, fruit and etc.) that is to be sterilized, and I then lend
the steam through and around that stuff, so that the latter is heated solely by the
steam. This steam after having passed, and heated, the respective stuff escapes
through the outlet..
This heating by means of the streaming steam is continued until the respective
stuff has got the same temperature as the fresh steam, when the process of steriliza-
tion will be finished.
I prefer to provide the lid or cover for the vessel with a hollow neck within
which are provided either two openings for simultaneously opening and closing
inlet and outlet, or one opening only and a cavity. In this case the neck of the
cover is extended in length so as to form a tube, which terminates shortly above
the bottom. This tube is brought in communication with the inlet, so that the
steam flowing into and through the neck of the cover, is compelled to pass the whole
contents of the vessel, whereby the said contents are sterilized.
Instead of arranging the steam-inlet in the neck of the bottle, I may arrange it
also in the lid or cover, and I may fix in this case to the cover a pipe, by means of
which the sterilized liquid, as for instance milk, may be sucked off, as is the case
with milk-bottles employed for little children.

Beverages, Remedies, and the like.
I, Dr. Med. Joseph Bassfreund, residing at Hildesheim, in the Province of
Hannover, Kingdom of Prussia, German Empire, Physician, 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 relates first, to a method of sterilizing water, milk and other
beverages and other victuals, as for instance, preserved fruits and the like, and
remedies for internal use as well as for external application, and is characterized
by leading streaming steam through, or around and through, the stuff to be
sterilized, the respective stuff being contained in a vessel that is not cooled at its
outer side, but is heated, and at the same time sterilized itself, solely by the said
streaming steam.
My invention consists, further, in the construction of special vessels for carrying
my new method into effect, the said vessels being characterized by having an inlet,
an outlet, and a cover or lid that is adapted to close one of, or both, the said
openings in such a manner, that in any case the sterilized contents of the
respective vessels are prevented against re-infection, and may yet be taken out
of the vessel in portions, as necessary, for instance, for the several repasts of a
little child.
In carrying my invention into effect, I take a bottle or vessel, which is provided
with an inlet and an outlet, the former having preferably a tube or pipe by means
of which the steam is led down onto the bottom of the vessel. Into the said vessel
has been put the stuff (milk, fruit and etc.) that is to be sterilized, and I then lead
the steam through and around that stuff, so that the latter is heated solely by the
steam. This steam after having passed, and heated, the respective stuff escapes
through the outlet.
This heating by means of the streaming steam is continued until the respective
stuff has got the same temperature as the fresh steam, when the process of steriliza-
tion will be finished.
I prefer to provide the lid or cover for the vessel with a hollow neck, within
which are provided either two openings for simultaneously opening and closing
inlet and outlet, or one opening only and a cavity. In this case the neck of the
cover is extended in length so as to form a tube, which terminates shortly above
the bottom. This tube is brought in communication with the inlet, so that the.
steam flowing into and through the neck of the cover, is compelled to pass the
whole contents of the vessel, whereby the said contents are sterilized.
it
Instead of arranging the steam-inlet in the neck of the bottle, I may arrange
also in the lid or cover, and I may fix in this case to the cover a pipe, by means of
which the sterilized liquid, as for instance milk, may be sucked off, as is the case
with milk-bottles employed for little children.
In order to make my invention more clear, I refer to the accompanying drawing,
in which similar letters denote similar parts throughout the several views, and in
which :.
Figs. 1 & 2 show the first mode of construction,
Figs. 3 & 4 show the second mode of construction,
Fig. 5 shows a third mode of construction,
Fig. 6 shows the fourth mode of construction,
Figs. 7 & 8 show the fifth mode of construction.
Referring to Figs. 1 & 2, a is the vessel or bottle intended to receive the stuff to

page_text: be sterilized; said vessel is in its neck provided with the steam-inlet a¹ and the
outlet a. The neck of the lid or cover is hollow, and is provided at one side
with an aperture b', and at its diametrically opposite side with a depression or
cavity. If the parts a and b are in the position shown in Fig. 1, the steam-
inlet a communicates with the aperture, whilst the depression or cavity lies
directly opposite to the outlet a².
or
The hollow neck of the lid or cover is elongated downwards, and terminates as
a conical tube 63. Therefore, the steam entering that tube through a' and ' is led
down by the same into the lowermost layer of the stuff contained within the vessel
bottle
a, or surrounding the tube 63 respectively. The steam giving off its heat.
to the stuff to be sterilized, as well as to the walls of the tube and vessel, will at.
first be condensed, but this condensation will after some time cease, and the stean
will then flow through and around the stuff in a constant stream, so that the
sterilization will now be completed. After the steam has flown out of the vessel
(at a) in a constant stream for a certain time (dependent on the sort of stuff to be
sterilized), the sterilization is finished, and both inlet and outlet are then simul-
taneously closed by turning the cover for 90° (compare Fig. 2), so that the stuff
is perfectly prevented from re-infection.
The cover of the bottle a may be elongated not only downwards, but upwards,
too, as shown in the mode of construction Figs. 3 & 4. The steam-inlet a¹ and the
aperture of the former mode of construction are then replaced by the channel of
the upper elongation (Figs. 3 & 4). This bottle with its tube 13 may directly
be employed for feeding little children with milk, or any other liquid nutritious.
matter.
In order to secure the sterilized contents of the bottle as much as possible against
re-infection, I prefer to furnish the bottle with an auxiliary cover c, Fig. 5, held in
place by an india-rubber cap c¹; and I furthermore cover the steam-outlet a² with
an india-rubber ring arranged within a suitable annular recess of the neck of
hottle a.
There is then gained the advantage, that the steam introduced into
bottle a can escape out of the same only after it has reached a certain tension,
sufficient to overcome the tension of the india-rubber ring ; owing to this tension,
the sterilisation will be completed in a correspondingly shorter time.
The portions of the sucking-tube need not indispensably be made in one
piece, and the intermediate portion need not itself form the cover, but there may be
used a special cover consisting preferably of two superposed parts, as shown in the
modification Figure 6. dare the two parts of the cover; part d is connected,
or made integrally, with the tube ; part d' is connected, or inade integrally, with
the tube. The outer part of the cover is formed into a cap provided with an
internal thread, and taking into an external thread provided on the neck of the
bottle a.
If the stuff to be sterilized requires but a comparatively low temperature
therefor, the elongations of the cover may entirely be dispensed with, as shown in
Figs. 7 & 8. The cover is in this case provided in its neck with two apertures ba
corresponding with the inlet a' and the outlet a². After the sterilisation has been
finished, the cover is turned for a certain angle, so as to interrupt the communication
between a b¹ on one side, and a 6 on the other side.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I'
claim is:-
1. The method of sterilizing, consisting in leading streaming steam onto and
through the stuff to be sterilized, substantially as described.
2. As a means for sterilizing by means of streaming steam, a bottle or vessel
having an inlet or inlets, an outlet or outlets, and means for leading the steam
through the stuff to be sterilized, substantially as described.
3. As a means for sterilizing by means of streaming steam, the combination with
a vessel a (Figs. 1 & 2) having steam-inlet a¹ and outlet a³, of a cover b having a

page_text: hollow neck with an aperture 6¹ and a depression or cavity, said neck being
elongated downwards into a tube 63, substantially as described.
4. As a means for sterilizing by means of streaming steam, the combination with
a bottle a having a steam-outlet a² (Figs. 3 & 4) of a tube widened in its
middle portion so as to form the cover for said bottle, said middle portion having a
depression or cavity b, substantially as described.
5. As a means for sterilizing by means of streaming steam, the combination with
a bottle a having a steam-outlet a' (Fig. 5), of a tube 63 widened in its middle
portion so as to form a cover for said bottle, said outlet a being covered by an
india-rubber ring arranged within an annular recess of the neck of said bottle a.
substantially as described.
6. As a means for sterilizing by means of streaming steam, the combination
with a bottle a having a steam-outlet a² (Fig. 5) of a tube 6463 widened in its
middle portion so as to form a cover for said bottle, the latter being provided
with a special outer cover c held by an india rubber cap c¹ substantially as
described.
7. As a means for sterilizing by means of streaming steam, the combination
with a bottle a (Fig. 6) of an inner cover d' having a tube and of an outer
cover d having a tube said two covers having steam-outlets, substantially as
described.
8. As a means for sterilizing by means of streaming steam, the combination with
a vessel a (Figs. 7 & 8) having an inlet a' and an outlet a² of a cover having a
hollow neck provided with a larger aperture 6 and a smaller aperture substan-
tially as shown and described.
9. In combination with sterilizing apparatus constructed in either of the
manners set forth in the preceding claims, the employment of any suitable
means or apparatus for generating steam for supplying same for the purposes
stated.
