I, JAMES DARSIE MORRISON, Surgeon Dentist, 27, Grange Road,
Edinburgh, Mid Lothian, North Britain, do hereby declare the nature
of the said Invention for " IMPROVEMENTS IN PURIFYING WATER OR OTHER
SOLVENTS SO AS TO QUALIFY THEM TO PURIFY OTHER BODIES BY SIMULTANEOUS
AND CONTINUOUS FILTERING AND SIMULTANEOUS AND CONTINUOUS DISTILLING
APPARATUS," to be as follows:-
This Invention may be described by first observing that the power
of water to dissolve animal, vegetable, and mineral matters depends on
its purity, and that whenever and whereever water is loaded with more
matters than it can carry in solution it then and there deposits from
that solution the overplus.
To carry out the object of this Invention I proceed as follows:-To
the street main water supply pipe I strongly solder a ground stop-cock
on which cock has been cast a coupling. To this coupling I couple a
syphon shaped moveable tubular filter filled with cotton wool, through

page_text: which the water passing upwards is filtered free from the heavier, and
in descending from the lighter, impurities carried by the checked current,
which but for this contrivance would get into the cistern. Between
the filter and the cistern I interpose instead of the ordinary ball cock
a valve composed of a short hollow piston connected with a hollow
plunger and acting within a cylinder, so that however raised from its bed
within the cylinder the water, hot or cold, passes through it to escape as
required when the valve is shut, as when no water is wanted the pressure
of the water keeps it so perfectly that all waste is prevented. From
this cistern is led the pipes of the house closed at every supply end by
a die impression valve through which flows as wanted mechanically but
not chemically pure water. To obtain water chemically pure a branch
of the mechanically purified water is led into the bottom of an upright
condenser. From the top of this condenser descends through a pipe a
fall of water to fill a cistern still placed between the condenser and
what I shall call the boiler still. From this interposed cistern still
heated to 211° a continuous stream of water at 211° constantly flows
into the bottom of the boiler still, which having but one degree of heat
to add constantly bursts into steam the running water as received. To
provide for the steam 1700 times the bulk of water a suitable receiver
overtops the boiler still and its condenser, the cistern still and its con-
denser, the entire heating appliances, in fact everything. From the
top of either or both condensers may be taken any number of branches
to supply with hot water baths, cooking apparatus, or a hot water
circulation of any kind, while from the steam receiver may be had pure
steam. This pure steam generated within perfectly insoluble apparatus
is chemically pure water at 213°. The boilers may be of any shape,
even tubular, like a poker which may conveniently be kept constantly
in the fire or at a small expence heated by gas, oil, or spirit.
The above Invention is applicable to all the purposes of science and
art especially the medical profession, physiologists, chemists, druggists,
and generally to all as a means of preserving health.
