page_text: J, CORNELIUS FITZGERALD BUCKLEY, of 715 Larkin Street, in the City
and County of San Francisco, State of California, U.S.A, Physician and Surgeon,
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 :-
My invention relates to the preservation of perishable articles especially
comestibles. The invention consists in enveloping and keeping said articles in
sterilized air, and in the apparatus in which this is carried out.
This apparatus is illustrated in the accompanying drawings in which the figure is
a general view.
A is a suitable compartment, having an outlet a which may be provided with a
check valve a¹.
Access is had to the compartment by a suitable door, as at a², and upon the
floor of the compartment, it will be found of advantage to put a layer of chloride of
sodium, such as is represented by B.
C is a vessel which has in it a suitable sterilizing substance or solution,
represented by c. Extending down into and below the surface of this solution or
substance is a pipe D, the other end of which, for the present, may be regarded as
being open to the exterior air.
From the vessel C, above the surface of the solution or substance therein, issues
a pipe E which extends into the compartment A.
If, now, the ordinary air in the compartment A he drawn out or driven out, its
place will be taken by air which passes through the pipe D, through the
sterilizing solution or substance in vessel C, and through the pipe E, and this air
will be sterilized by passing through said solution or subtance.
The materials to be preserved are put into the compartment A, and they are thus
enveloped by sterilized air; and as long as they are thus kept, they will remain in
a state of preservation and can be transported for great distances and kept as long
as necessary.
The displacement of the original air may be effected in any suitable manner, as
by means of an exhaust action, or by means of the forcing of the incoming sterilized
air into the compartment, whereby the original air is driven out.
The sterilizing of the air may be accomplished in a single vessel, such as C, but
in order to thoroughly sterilize it, it may be caused to pass through a series of such
vessels containing the same or a different substance or solution, preferably
substances or solutions of different character.
To show such series I have illustrated other vessels C1, C2, C3 and C4, and other
pipes D', D', D' and D', which connect the space within each vessel above the
sterilizing substance, with the space below the sterilizing substance in the succeeding
vessel; and under the last pipe D, which communicates with the exterior air,
have shown, as a means of producing a current through this series of vessels, a
lamp F, though it will be understood that any other means may be used, such as an
air pump, or blower, or other device.
In vessel C I place a 10 per cent. solution of formalin in alcohol. In vessel C₁
In vessel C' the
the sterilizing substance c is a chloride of sodium solution.
substance is water. In vessel C the substance c' is a solution of per-chloride of
iron. In vessel C₁ the substance is bi-chloride of mercury.

page_text: It will be well to have the solution or substance in the vessel C, of a volatile, as
well as a sterilizing character, in order that the vapors may be carried into the
compartment by the air.
The solution of formalin in alcohol, mentioned, is of a volatile character, and in
this connection I may also mention an alcoholic solution of lysol.
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-
air.
1st. Preserving perishable articles by enveloping and keeping them in sterilized
2nd. The improvement in preserving perishable articles, which consists in
enveloping and keeping them in sterilized air, obtained in any suitable manner,
though preferably by passing ordinary air through a sterilizing substance, or
through a series of such substances of the same or of different characters.
3rd. The improvement in preserving perishable articles, which consists in
enveloping and keeping them in sterilized air, obtained in any suitable manner,
though preferably by passing ordinary air through a sterilizing substance, or
through a series of such substances of the same or of different characters, one or
more of such substances being of a volatile, as well as a sterilizing character,
whereby the vapor of said substance may be carried by the air into the
compartment in which the articles to be preserved are enveloped.
4th. An apparatus to be used in the preservation of perishable articles, consisting
of a compartment in which said articles are placed, and a series of vessels exterior
to said compartment and containing sterilizing solutions or substances of the same
or different characters, said vessels being connected in succession by means of pipes
joining the upper space of each with the space below the solution or substance of
the succeeding one, the last of the series being connected by a pipe with the
compartment in which the articles are placed, and a means for causing a current of
air through said connected vessels and into the compartment.
