Improvements in Condensing Chambers for Sublimed Sulphur.
I JAMES YATE JOHNSON of 47 Lincolns Inn Fields in the County of Middlesex
Gentleman 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 relating to condensing chambers for sublimed Sulphur consists in
providing means as hereinafter described for separating Sulphur sublimed by the
action of Steam from the moisture carried over with the Sulphur into the condensing
chamber.
The sublimed Sulphur obtained by means of steam is usually collected in a very
moist or wet condition in the condensing chambers as heretofore arranged and requires
to be dried before it can be placed in the market. By means of this Invention this
disadvantage is obviated and the subsequent drying process rendered unnecessary.
With this object in place of receiving the sulphur directly upon the floor of the
chamber as heretofore practised the chamber is provided with a cloth or cloths
stretched or suspended af. a suitable height above the floor. The Sulphur is deposited
on this cloth or cloths but the water of condensation filters or percolates through them
and is drained off along suitable inclines formed on the floor. The chamber may be
made without any floor in which case the water falls directly onto the ground.
According to this Invention also the whole or part of the sides and roof of the
condensing chamber are made of cloth or woven fabric. The steam passes through
the cloth and the Sulphur being retained falls inside the chamber. By thus providing
for the escape of the steam the back pressure which is liable to retard the vaporization
or sublimation of the Sulphur is removed.
The chamber may be constructed entirely of cloth supported on a framework of
wood masonry or iron. It is not absolutely necessary for the roof or even a part of
the walls of the chamber to be composed of cloth, a cloth stretched at a certain height

page_text: from the bottom of the chamber being sufficient to collect the sulphur in a dry
condition.
The cloths may be made of any suitable material such as cotton hemp flax silk or
even wire.
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:
First. In a chamber for condensing Sulphur sublimed by the action of steam the
employment of a cloth stretched at a convenient height from the floor or bottom of the
chamber for the purpose of collecting the Sulphur and separating it from the water of
condensation substantially as hereinbefore described.
Second. In a chamber for condensing Sulphur sublimed by the action of steam the
arrangement consisting in forming a portion of the walls or roof of the chamber of
cloth substantially as hereinbefore described.
Third. A Chamber for condensing Sulphur constructed entirely of cloth supported
on a suitable framework substantially as hereinhefore described.
