1, JOHN WHITWORTH LORD of Fairfield Road Bow in the County of Middlesex
Engineer do hereby declare the nature of this invention to be as follows:-
This invention relates to an improvement applied to apparatus used in the
expression of oil from substances and it has for object the thorough heating of
the substances under pressure.
For this purpose I enclose the press, which may be of any suitable kind, within a
casing or jacketing so constructed as to give access to the press for the introduction
and removal of the substance to be treated, and to permit the escape of the oil and the
working of the press. Into this casing or jacketing I introduce, from any convenient
source, steam, superheated steam, or hot air, thus enclosing the press within a heated
chamber the heat in which may be raised to an extent which will cause it to
penetrate or permeate the entire mass under treatment, thereby greatly facilitating
the extraction of the oil and obtaining a larger yield than could be obtained fron
a press operating exposed to the atmosphere or with heat only partially applied
thereto.

I, JOHN WHITWORTH LORD of Fairfield Road Bow in the County of Middlesex
Engineer 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 to an improvement applied to apparatus used in the expression
of oil from substances and it has for object the thorough heating of the substances a
under pressure.
For this purpose I enclose the press, which may be of any suitable kind, within a
casing or jacketing so constructed as to give access to the press for the introduction
and removal of the substance to be treated, and to permit the escape of the oil and
the working of the press. Into this casing or jacketing I introduce, from any
convenient source, steam, superheated steam, or hot air, thus enclosing the press
within a heated chamber the heat in which may be raised to an extent which will
cause it to penetrate or permeate the entire mass under treatment, thereby greatly
facilitating the extraction of the oil and obtaining a larger yield than could be obtained
from a press operating exposed to the atmosphere or with heat only partially applied
thereto.
The accompanying drawing shows an apparatus embodying my invention :-
Figure 1 being an elevation of the apparatus.
Figure 2 part section through jacket and
Figure 3 section at plan.
A indicates the press (which may be of any kind). B jacketing surrounding same
and forming heated chamber enclosing press.
O door in jacket for introduction of the substance to be treated. D, D, D, D, inlets
for steam, superheated steam, or hot air to jacket B. E pipe for discharging oil into
suitable tanks or receivers.
.
I desire it to be understood that I do not limit myself to the particular construction
and arrangement of apparatus shown on the drawing, as such may be modified while
retaining the essential characteristic of my invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed 1 declare that what
I claim is :-
In apparatus for expressing oil from substances, enclosing the press within a casing
or jacketing heated by steam, superheated steam, or hot air, permitting the working
of the press as in a heated chamber, with means of access thereto and removal
therefrom, substantially as described.
