We JAMES SIMPSON, and EDWARD WILLIAM PARNELL, of Rumford Place, Liver-
pool, in the county of Lancaster, Manufacturing Chemists, do hereby declare the
nature of this invention to be as follows:-—
In the various methods which have been proposed for the separation of sulphur
from sulphuretted hydrogen by burning the gas in a suitable burner or combustion
chainber with only sufficient oxygen or atmospheric air to combine with the hydrogen
so as to realize the reaction H, S + 0 = H,O + S or for obtaining sulphurous acid
of uniform strength according to the reaction H, S +30= H₂O + SO, a great
difficulty has always been encountered in regulating the respective currents of air
and sulphuretted hydrogen entering the burner or combustion chamber, the result
being that sometimes air in excess has caused the loss of sulphur as sulphurous acid
or a deficiency of air has caused sulphuretted hydrogen to pass away undecomposed.
The object of our Invention is, in conducting either of the foregoing reactions, by
a simple and efficient apparatus to regulate the supply of air and gas any desired
proportions, to measure the quantity of gas consumed and to minimise the risk of
explosion by firing back.
in
For this purpose we employ two vessels or cylinders each of which is provided
with an inlot and an outlet valve both of which vessels are filled and emptied
simultaneously by any well known mechanical arrangement such as cylinders and
pistons or gasholders raised and lowered in tanks of liquid. The inlet valves of the

page_text: vessels or cylinders are connected respectively with the sulphuretted hydrogen
generator or storage tank, and with the atmosphere; and the outlet valves are
connected with the burner or combustion chamber.
The working parts of such mechanical arrangement are so coupled that the two
vessels or cylinders shall act in conjunction so that the air or gas entering and leaving
one of the vessels or cylinders in a given time shall have a constant ratio or proportion
to the quantity of air or gas entering and leaving the other vessel or cylinder during
the same period.

WO, JAMES SIMPSON and EDWARD WILLIAM PARNELL of Rumford Place, Liver-
pool, in the County of Lancaster Manufacturing Chomists 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 :-
In the various methods which have been proposed for the separation of Sulphur
from Sulphuretted hydrogen by burning the.gas in a suitable furnace or Combustion
chamber with only sufficient oxygen or atmospheric air to combine with the
hydrogen so as to realise the reaction-H, S +0 = H₂O+S or for obtaining
sulphurous acid of uniform strength according to the reaction H, S+30=H₂O+SO,
-A great difficulty has always been encountered in regulating the respective
currents of air and sulphuretted hydrogen entering the burner or combustion
chamber-The result being that sometimes air in excess has caused the loss of
sulphur as sulphurous acid, or a deficiency of Air has caused sulphurotted hydrogen
to pass away undecomposed.
The object of our invention is to conduct either of the foregoing reactions by a
simple and efficient apparatus to regulate the supply of air and gas in any desired
proportions to measure the quantity of gas consumed and to minimise the risk of
explosion by firing back.
For this purpose we employ two vessels or cylinders each of which is provided
with an inlet and an outlet valve-both of which vessels are filled and emptied
simultaneously by any well known mechanical arrangement such as cylinders and
pistons or gasholders raised and lowered in tanks of liquid. The inlet valves of the
cylinders or vessels are connected respectively with the sulphuretted hydrogen
generator or storage tank and with the atmosphere and the outlet valves are con-
nected with the burner or Combustion chamber.
The working parts of such mechanical arrangement are so coupled that the two
vessels or cylinders shall act in conjunction so that the air or gas entering and
leaving one of the vessels or cylinders in a given time shall have a constant ratio or
proportion to the quantity of air or gas entering and leaving the other vessel or
cylinder during the same period.
The drawing herewith illustrates a form of apparatus under our invention, a a¹
vessels suspended from the beam 6 by means of hangers c. The said hangers are
capable of adjustment in bearings d to or from the centre of oscillation e of the
beam b.-Screw or other suitable gear is used for regulating the position of the
hangers, tanks containing water in which the vessels a a' are suspended g standards
carrying the bean b, harm attached to the beam b.-i crank for giving motion to the
arm h. and with it the beam by means of the crank pin i* working in the slot j―

page_text: kinlet pipes and valves, outlet pipes and valves.-The pipes lead from the
vessels a to the atmosphere; the pipes from the vessels a³ to the sulphuretted hydrogen
supply, the pipes Z. lead from the vessels a a¹ to the burner or combustion chamber.
The vessels a are for regulating the atmosphere supply and the vessels a for
sulphuretted hydrogen. The diameters of the vessels and the length of stroke are
such that the atmosphere and sulphuretted hydrogen are drawn into the vessels and
sent forward to the burner in the required proportions-When sulphur is to be
obtained, about five volumes of atmospheric air to two of sulphuretted hydrogen are
required; when sulphurous acid is to be obtained the proportions are about eight to
one; when it is intended to obtain sulphuric acid the proportions are about ten to
one The requisite nicity of measurement of the air and gas is obtained by adjusting
the hangers of the vessels the required distance from the fulcrum, or point of
oscillation of the beam. To prevent absorption the water may be covered with blue
oil or liquid lighter than water.
It will be evident that numerous modifications of apparatus may be made under our
⚫nvention.
Having now particularly described and ascertained the nature of the said invention,
we declare that what we claim is :-
First Apparatus for use in the treatment of Sulphuretted hydrogen, substantially
as set forth.
Second In apparatus for the treatment of sulphuretted hydrogen to obtain sulphur
or sulphurous acid the combination of two or more measuring vessels with inlet and
discharge pipes and valves for the purpose set forth.
