PROVISIONAL SPECIFICATION.
Improvements in Retorts for Use in Making Charcoal or for like
Operations.
We EDWARD RIDER COOK Chairman of The Animal Charcoal Company of 11 New
Gravel Lane Shadwell in the County of Middlesex and JOHN WILLIAM INGHAM of
11 New Gravel Lane aforesaid Chemist do hereby declare the nature of this Invention
to be as follows:-
:-
The object of this Invention is to reduce the cost and weight of retorts and to
simplify their operation for discharging the contents and further to make the length
available for the charring or heating operation readily adjustable.
According to this Invention a false bottom is provided it being supported at the
desired distance inwards of the discharge lid by a rod or support passing through the
discharge lid and supported by a bar or rest which may be the end of the screw which
passes through the cross-bar of the discharge lid the said rest or end acting also as a
means of closing tightly the opening through which the rod or support passes. The
length of this rod or support therefore determines the length of the retort which is
available for the charring or like operation. When the contents are to be discharged
the cross-bar is unfastened and turned down and as the rest for the rod or support
of the false bottom is removed with it, the rod or support, under the weight of the
charge on the false bottom, runs outwards through the opening in the lid until the
false bottom rests on the lid. The lid is received preferably on bars or rails situated
at a short distance below it and upon which it can be withdrawn sideways for
discharging the contents of the retort.

Improvements in Retorts for Use in Making Charcoal or for like
Operations.
We, EDWARD RIDER COOK Chairman of The Animal Charcoal Company of 11 New
Gravel Lane Shadwell in the County of Middlesex and JOHN WILLIAM INGHAM of
11 New Gravel Lane aforesaid Chemist do hereby declare the nature of this Inven-
tion 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 reduce the cost and weight of retorts and to
simplify their operation for discharging the contents and further to make the length
available for the charring or heating operation readily adjustable.
According to this Invention a false bottom is provided capable of moving in a line
with the length of the retort in discharging the contents of the retort it being supported
at the desired distance inwards of the discharge lid or cover by a rod or support
preferably capable of passing through the discharge lid or cover and supported by a
bar or rest which may be the end of the screw which passes through the cross-bar of
the discharge lid or cover the said rest or end acting also as a means of closing
tightly the opening through. which the rod or support passes. The length of this rod
or support therefore determines the length of the retort which is available for the
charring or like operation. When the contents are to be discharged the cross bar is
unfastened and turned down and, as the rest for the rod or support of the false bottom
is removed with it, the rod or support, under the weight of the charge on the false
bottom, runs outwards through the opening in the lid or cover until the false bottom
rests on the lid or cover. The lid or cover is received preferably on bars or rails
situated at a short distance below it upon which bars or rails it can be withdrawn
sideways for discharging the contents of the retort.
And in order that our said invention may be fully understood we shall now
proceed more particularly to describe the same and for that purpose shall refer to
the several figures on the annexed sheets of drawings the same letters of reference
indicating corresponding parts in all the figures.
Figure 1 is a vertical section of a retort provided with an arrangement according
to our Invention showing the lid or cover closed and Figures 2 and 3 are vertical
sections at right angles to each other showing the lid or cover open.
In the retort A, is a false bottom B provided with a rod b resting when the
cover is closed upon the coned rest at the end of the screw D which is screwed
through a female screw in the cross-bar E which is hinged at one end and secured
at the other end by a pin or cotter e passed through holes in the end of the cross-bar
and in the lugs a secured to the retort. The coned rest & fits into a corresponding
coned, hole in the centre of the cover C.
Fare rods or rails upon which the cover Crests when it is lowered.
the retort is to be used the parts are in the position shown in Figure 1 the
screw enabling a tight closure of the coned hole in the cover and of the cover
When

page_text: against the mouth of the retort to be effected. When the contents of the retort
have been sufficiently treated the cotter e is withdrawn and the bar E turned
down when the weight of the charge forces down the false bottom B the rod b
passing through the coned hole in the cover and the cover coming to rest on the
rods or rails F as shown in Figures 2 and 3. The cover can then be drawn side-
ways along the rods or rails F clear of the retort opening to allow free discharge
of its contents.
We have shown the rods or rails F as being hinged at one end and at the other
end provided with an extension passing through an eye in the bracket G the
extension and eye g being perforated so that by means of a pin h the said rods or
rails can be supported in the position shown in Figure 3 when they are to receive the
lid and be afterwards lowered so that they are inclined to allow the cover to slide away
from the retort opening.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what we
claim is :-
1. In vertical or approximately vertical retorts a false bottom which when the
charge is to be withdrawn is lowered in a line parallel with the length of the retort
substantially as hereinbefore described.
2. In vertical or approximately vertical retorts a false bottom provided with
a stem or support resting on the closing device substantially as hereinbefore
described.
3. In vertical or approximately vertical retorts the combination of a false bottom
provided with a stem seated upon the end of a screw or equivalent device
which forms the means of supporting and releasing the false bottom and of
effecting a tight closure of the retort end substantially as herein before described.
4. The arrangement and combination of parts constituting the means for supporting
the charge of a retort and for releasing its contents substantially as herein before
described and illustrated in the accompanying drawings.
