This Invention relates to improvements in or applicable to our apparatus for
condensing, washing, and purifying gas and other vapours, for which Letters
Patent were granted to us dated the Twenty ninth day of December, One thousand
eight hundred and seventy seven, No. 4928, the object of the present improvements
being to increase the frictional condensing power of the machine, and thereby to
more effectually arrest the volatile oils carried forward with the gas.
One arrangement for carrying out our improvements consists in the construction
and application to the peripheries of the clusters of plates or discs described in the
Specification of our former Letters Patent of a suitable number of plates forming
drums, such plates or drums being perforated with a number of holes throughout,
about half their circumference at one side, the said perforations in the respective
plates or drums being either opposite one another, or alternately on opposite sides
Din 21

page_text: of the drums; the said perforated plates or drums are fixed in any suitable manner,
such as by means of wooden rings.
By the employment of these perforated plates or drums constructed and arranged,
as hereinbefore described, the frictional condensing power of the machine is
increased and the volatile oils carried forward by the gas are more effectually
arrested and deposited as the gas passes through the perforations in the drums.
In a modification of our improvements wo dispense with the clusters of discs or
plates, herein before described, in all or in some of the divisions of the apparatus,
and employ in place thereof segments constructed of a number of perforated plates
similar to those hereinbefore described, and enclosed at the ends, whereby the
action of the apparatus is much improved.
In some cases in place of the concentric perforated plates we employ plates
parallel with the clusters of discs and perforated in a series of concentric rings, and
the ordinary perforated end plates of the clusters are provided with sliding plates
operated by a screw or otherwise for the purpose of rotating the sliding plates so
as to partly close the perforations and thus allow of regulating or controlling the
passage of the gas through the apparatus.

This Invention relates to improvements in or applicable to the apparatus for
condensing, washing, and purifying gas and other vapours, for which Letters
Patent were granted to Thomas Nesham Kirkham, David Hulett, Samuel Chandler,
senior, and Samuel Chandler, junior, dated the Twenty ninth day of December
One thousand eight hundred and seventy seven, No. 4928, the object of the
present improvements being to increase the frictional condensing power of the
machine, and thereby to more effectually arrest the volatile oils carried forward
with the gas.
One arrangement for carrying out our improvements consists in the construction
and application to the peripheries of the clusters of plates or discs described in the
Specification of the said former Letters Patent of a suitable number of plates.
forming drums, such plates or drums being perforated with a number of holes
throughout, about half their circumference at one side, the said perforations in the
respective plates or drums being either opposite one another or alternately on
opposite sides of the drums; the said perforated plates or drums are fixed in any
suitable manner, such as by means of wooden rings.
In a modification of our improvements we dispense with the clusters of discs or
plates, hereinbefore described, in all or in some of the divisions of the apparatus,
and employ in place thereof segments constructed of a number of perforated plates.
similar to those herein before described, and enclosed at the ends, whereby the
action of the apparatus is much improved.
In some cases, in place of the concentric perforated plates, we employ plates
parallel with the clusters of discs, and perforated in a series of concentric rings,
and the ordinary perforated end plates of the clusters are provided with sliding
plates operated by a screw or otherwise for the purpose of rotating the sliding
plates so as to partly close the perforations, and thus allow of regulating or
controlling the passage of the gas through the apparatus.
But to make our Invention better understood we will proceed to describe the
same by reference to the accompanying Drawing, in which Figure 1 is a vertical
transverse section of our improved apparatus provided with perforated plates on
the peripheries of the clusters of plates or discs; Figure 2, a longitudinal section of
one compartment of the apparatus shewing the cluster of plates or discs in section,
and Figure 3 is a similar view shewing the discs or plates in side elevation;
Figures 4, 5, and 6 represent a front elevation, a side elevation, and a cross section
respectively, shewing the modification of the apparatus in which we dispense with
the clusters of discs or plates; Figure 7 enlarged detail; Figures 8 and 9, cross
sections, and Figure 10 part longitudinal section of the arrangement of apparatus
having the perforated plates parallel with the clusters of discs. Similar letters in
all the Figures represent similar or corresponding parts.
In Figures 1, 2, and 3, A is the ordinary cast iron vessel; B, the partitions ;
C, the horizontal shaft carrying the discs D, all substantially as described in the
Specification of the said former Letters Patent; E, E; are the plates forming drums

page_text: which we apply to the peripheries of the clusters of plates or discs D; these plates
or drums are perforated, as shewn and as hereinbefore described; F, F, are wooden
rings for fixing the perforated plates or drums E, E.
By the employment of these perforated plates or drums E, E, constructed and
arranged as hereinbefore described and shewn, the frictional condensing power of
the machine is increased and the volatile oils carried forward by the gas are more
effectually arrested and deposited as the gas passes through the perforations in the
drums.
In the arrangement shewn in Figures 4, 5, and 6 we dispense with the
hereinbefore described clusters of plates or discs D in all or in some of the divisions
of the apparatus, and employ in place thereof segments constructed of a number of
perforated plates G, G, similar to those marked E, E, in Figures 1, 2, and 3; these
plates are enclosed at the ends; the direction of the passage of the gas is shewn
by the arrows in Figure 7, which is an enlarged detail in cross section of the
plates.
In Figures 8, 9, and 10, H, H, shew the plates we sometimes employ in place of
the concentric perforated plates hereinbefore described and marked G, G, these
plates H, H, are parallel with the clusters of discs D and perforated, as shewn in a
series of concentric rings, and the ordinary end plates of the clusters are provided
with slots G¹ and with sliding plates I so as to partly close the perforations J, and
thus allow of controlling or regulating the passage of the gas through the apparatus.
The sliding plates I may be operated by a screw or otherwise as may be found
most convenient.
Having thus described the nature of our said Invention and the best means
with which we are acquainted for carrying the same into effect, we would have it
understood that we do not confine ourselves to the precise details herein laid
down and shewn in the accompanying Drawing, as the same may be varied
without departing from the peculiar character of the Invention, but what we do
claim is,―
Firstly. The construction and application to the peripheries of the clusters. of
plates or discs in apparatus for condensing, washing, and purifying gas and other
vapours, of a suitable number of perforated plates or drums arranged and operating
substantially in the manner and for the purposes herein before described and
illustrated in Figures 1, 2, and 3 of the accompanying Drawing.
Secondly. The modification of the apparatus as hereinbefore described and
represented in Figures 4, 5, 6, and 7 of the accompanying Drawing.
Thirdly. The employment of the perforated plates parallel with the clusters of
discs, the ordinary end plates of the clusters being perforated and provided, as
described, with sliding plates, substantially as and for the purpose hereinbefore
described and represented in Figures 8, 9, and 10 of the accompanying Drawing.
In witness whereof, I, the said Thomas Hersey, for and on behalf of myself
and the said Thomas Nesham Kirkham, David Hulett, Samuel Chandler,
senior, Josiah Chandler, and Samuel Chandler, junior, have hereto set my
hand and seal, this Twenty fourth day of September, in the year of our
Lord One thousand eight hundred and eighty one.
