Improvements in Sterilising Liquids and in Apparatus therefor.
I, LEOPOLD NATHAN, of Rigistrasse, Zurich, Switzerland, Physiological Chemist,
do hereby declare the nature of this invention to be as follows, that is to say: -
My said invention has for its object to obtain improved and reliable results in
treating liquids for the purpose of sterilising ferments, or other germs.
My invention is more specially applicable for treating potable liquids or bever-
ages, such as are usually stored in bottles or similar vessels, some air being ordi-
narily confined in the bottles or vessels along with the liquid. The sterilising is
effected by causing the liquid to be heated to a suitable temperature, it being
generally desirable to employ the lowest temperature which will effect complete
sterilisation. As is well known, the temperature necessary to produce sterilisa-
tion is different for different liquids; when, however, some air is confined in the
bottle or vessel containing the liquid, a higher temperature than would otherwise
be necessary has hitherto been required to insure the complete sterilising of fer-
ments or other germs in the air as well as in the liquid.
By my invention I cause the liquid and air in the bottles or vessels to be
continuously or intermittently agitated or mixed, during the beating process, in
order that the liquid may wash out or absorb ferments or other germs from the air,
and at the same time equalise the temperature throughout each bottle or vessel,
with the result that a comparatively lower temperature may be satisfactorily and
advantageously employed.
In carrying out my invention I employ a receiving vessel or casing in which
the bottles or vessels can be packed in a manner to avoid displacement of them-
selves or of their corks or stoppers; and I apply the sterilising heat by introduc-
ing steam or a heated liquid into the receiving vessel. This receiving vessel is
mounted on or suspended from journals or is otherwise arranged so that an oscil-
lating, swinging, or other reciprocating motion may be imparted to it from any
convenient prime mover, in a manner to make the liquid in the bottles or vessels
move to and fro' or be agitated and mixed with the air.
The results obtainable by the application of my invention are more certain
than those obtained hitherto; in other words the percentage of imperfect sterilisa-
tions is much smaller.

I, LEOPOLD NATHAN, of Registrasse, Zurich, Switzerland, Physiological Chemist,
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 follow-
ing statement, that is to say:
-
My said invention has for its object to obtain improved and reliable results in
treating liquids for the purpose of sterilising ferments, or other germs.
My invention is more specially applicable for treating potable liquids or bever-
ages, such as are usually stored in bottles or similar vessels, some air being ordi-
narily confined in the bottles or vessels along with the liquid. The sterilising is
effected by causing the liquid to be heated to a suitable temperature, it being
generally desirable to employ the lowest temperature which will effect complete
sterilisation. As is well known, the temperature necessary to produce sterilisa-
tion is different for different liquids; when, however, some air is confined in the
bottle or vessel containing the liquid a higher temperature than would otherwise
be necessary has hitherto been required to insure the complete sterilisation of fer-
ments or other germs in the air as well as in the liquid.
By my invention I cause the liquid and air in the bottles or vessels to be
order
intermittently agitated or mixed, during the heating process, in
that the liquid may wash out or absorb ferments or other germs from the air,
and at the same time equalise the temperature throughout each bottle or vessel,
with the result that a comparatively lower temperature may be satisfactorily and
advantageously employed.
In carrying out my invention I place a number of the bottles or vessels contain-
ing the potable liquids or beverages in a receiving vessel or casing of any con-
venient form or kind, the said bottles or vessels being packed or secured so as not
to move about the vessel or casing; and I apply the sterilising heat by introducing
steam or a heated liquid into the receiving vessel. This receiving vessel is
mounted on or suspended from journals or is otherwise arranged so that an oscil-
lating, swinging, or other recpirocating, but not continuous, motion may be
imparted to it from any convenient prime mover in a manner to make the liquid
in the bottles or vessels move to and fro' or be agitated and mixed with the air.
I append a sheet of explanatory drawings showing by way of example a simple
and convenient arrangement of apparatus for carrying out my invention Figure, 1,
being a sectional plan; and Figure, 2, a sectional side elevation.
I employ a receiving vessel or casing, A, made of wood lined with metal, B,
the cover, C, being suspended by cords, D, passing over a pulley, E, so that it
can be speedily and easily raised or lowered when required, as shown in Figure, 2.
When in position on the casing, A, the cover, C, is secured by bolts, F, hinged
to the sides and ends of the casing and being turned up into slots, G, formed in
the edge of the cover, nuts, H, on the ends of the bolts being then screwed down
so as to bear on the edge of the cover. When the cover, C, is raised the worker
packs the bottles, J, into the vessel, A, division boards, K, being
placed loosely in the vessel
each pile of bottles, J. When the vessel, A, is filled, screwed
spindles, L, made with handles, M, and turning in bosses, N, are screwed out so
that the ends of the spindles, L, bear on the division board, K, at that end of
the vessel, A, this causes all the division boards to bear on the bottoms and corks
or stoppers of the bottles and thus make sure that the bottles cannot move about
the vessel, A. The vessel, A, is mounted on or suspended from journals, P, and a
80 as
to extend
across
the vessel between

page_text: swinging motion is imparted to it through a connecting rod, Q, from a crank pin, R,
driven by any suitable means.
The bottles are covered with water which may be pumped in through a pipe, V,
or supplied in any other suitable manner and the sterilising heat is applied by
introducing steam through a pipe, S, led through one of the journals, P, and
connected to distributing pipes, T, placed beneath a loose false bottom, U, in the
vessel, A. The pipe, V, may also act as an overflow and a thermometer, W, is
attached to the vessel, A.
The results obtainable by the application of my invention are more certain
than those obtained hitherto; in other words the percentage of imperfect sterilisa-
tions is much smaller.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
The process of sterilising potable liquids or beverages by heat in which the
containing bottles or vessels are subjected to an oscillating, swinging, or other
reciprocating, but not continuous, motion whilst being heated, substantially as
and for the purpose hereinbefore described.
2. In apparatus for sterilising liquids a receiving vessel or casing for holding the
containing bottles or vessels, the receiving vessel being subjected to an oscillating,
swinging or other reciprocating, but not continuous, motion substantially as and
for the purpose herein before described.
