PROVISIONAL SI POTER
Improved Apparatus for Use in Sterilizing, and for Closing Bottles
Containing Sterilized Material.
I, KARL FLAACK, of Hagenstrasse 13, Brunswick in the Empire of Germany,
Manager, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide for the convenient sterilizing of materials,
such as for instance milk, in bottles and for the convenient closing of the bottles
containing the sterilized material as they are brought from the sterilizing chamber
or vessel.
For these purposes I provide a closed chamber or vessel of sufficient size and at
one end or side thereof a door is provided so that it may be removed for entrance
of a trolley or frame into the vessel and for its removal at the end of the process
of sterilizing, and during the process may be suitably secured steam tight. Pipes
and valves are provided for permitting steam to enter, pass through and escape
from the said vessel or chamber.
The trolley or frame is intended to carry a convenient number of bottles
arranged in rows. These bottles are filled or partially filled with the material to
be sterilized, placed on the trolley, and passed into the chamber or vessel.
I prefer to use bottles provided with a stopper which may be secured in the
mouth of the bottle by a well known system of two stout wire bows connected so
that the downward thrust of one of these bows towards the neck of the bottle
Previous to and
closed down the stopper over which the other bow passes.
during the sterilizing process the stoppers are placed on the mouths of the bottles
but are not fastened down. To provide for a convenient closing of all the bottles
in each row when the trolley being drawn out of the sterilizing chamber or
vessel after the sterilizing is done, I provide near or across the entrance to the
said chamber or vessel a cross bar or bars adapted to be depressed by a lever or
levers from time to time while the trolley is being drawn out so as to meet the
aforesaid closing bows of all the stoppers in each row or rows and press them down
simultaneously and thus securely close all the bottles in each row or rows.
It is preferable to provide a spring or springs to lift the bar or bars after each
such depression.

COMPLETE SPECIFICATION.
Improved Apparatus for Use in Sterilizing, and for Closing Bottles
Containing Sterilized Material.
I KARL FLAACK of Hagenstrasse, 13, Brunswick in the Empire of Germany,
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 :-
The object of this invention is to provide for the convenient sterilizing of
materials such as, for instance, milk in bottles and for the convenient closing of
the bottles containing the sterilized material as they are brought from the
sterilizing chamber or vessel.

page_text: For these purposes I provide a closed chamber or vessel of sufficient size and at
one end or side thereof a door is provided so that it may be removed for entrance
of a trolley or frame into the vessel and for its removal at the end of the process
of sterilizing, and during the process may be suitably secured steam-tight. Pipes
and valves are provided for permitting steam to enter, pass through and escape
from the said vessel or chamber.
The trolley or frame is intended to carry a convenient number of bottles
arranged in rows. These bottles are filled or partially filled with the material to
be sterilized, placed on the trolley, and passed into the chamber or vessel.
I prefer to use bottles provided with a stopper which may be secured in the
mouth of the bottle by a well known system of two stout wire bows connected so
that the downward thrust of one of these bows towards the neck of the bottle
closes down the stopper over which the other bow passes. Previous to and
during the sterilizing process the stoppers are placed on the mouths of the bottles
but are not fastened down. To provide for a convenient closing of all the bottles
in each row when the trolley is being drawn out of the sterilizing chamber or
vessel after the sterilizing is done, I provide near or across the entrance to the
said chamber or vessel a cross bar or bars adapted to be depressed by a lever or
levers from time to time while the trolley is being drawn out so as to meet the
aforesaid closing bows of all the stoppers in each row or rows and press them down
simultaneously and thus securely close all the bottles in each row or rows.
It is preferable to provide a spring or springs to lift the bar or bars after each
such depression.
In the annexed drawing,
Fig. 1 represents a longitudinal sectional view, Fig. 2 a plan view of the
apparatus,
Figs. 3 and 4 are views of the front part of the apparatus, Fig. 4 showing
especially said front part with trolley partially withdrawn.
This improved sterilizing apparatus consists of a vessel or chamber A into
which steam is passed through two pipes B and B¹. At one of the front sides a
door C capable of being closed by screw bolts and lugs is provided, which when to
be opened, is drawn up by means of a chain E in connection with the counter
weight F. The bottles containing the liquid to be sterilized, such as milk, are
placed in series upon the trolley or rolling support D which is drawn through the
open door and after the process is finished, drawn out again in the same manner.
G, G' and G2 are thermometers. H is a safety valve.
On the front side of the sterilizing chamber a horizontal flat iron rail or bar J
is arranged which serves to produce the closure of the bottles as the trolley is
drawn out to bring the bottles under it; the rail when lowered strikes the closing
bows of a row of bottles as shown in Fig. 4. If now said flat iron rail is further
lowered the closing bows will be depressed to such extent that they will
automatically effect the closure of the bottles.
Several of such rails or bars may be arranged side by side so that always a
respective number of rows of bottles may be closed simultaneously. The down-
ward movement of the rail or rails J is effected by actuating the lever K, this
latter forcing down the bar L and the bar L on its part drawing down said rail .J.
A strong helicoidal spring h causes the rail J to rise automatically when the lever
is released. At the opposite end of the rail J a corresponding arrangement is
provided and both of them are actuated simultaneously.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, I declare that what I
claim is,
1. The combination with the sterilizing chamber of a trolley adapted to receive
the receptacles containing the liquid to be sterilized to be drawn into the
sterilizing vessel and after the process is finished drawn out again in the same
manner substantially as described.

page_text: 2. The combination with the sterilizing chamber having at the exit side an
arrangement for closing the bottles placed in rows upon a movable trolley, said
bottles being provided with a bottle closing device of the nature described, said
arrangement consisting of one or more horizontal rails J capable of being lowered
and lifted in such a way that said rail or rails will strike the closing bows of said
bottle-closing-device substantially as and for the purpose set forth.
