I WALLACE FAIRWEATHER, C.E. of 96 Buchanan Street, Glasgow, in the County
of Lanark, Fellow of the Institute of Patent Agents, do hereby declare the nature
of the said Invention for "AN IMPROVED FILTERING MEDIUM, AND MODE OF
EMPLOYING THE SAME FOR FILTERING, DECOLORISING, AND DEODORISING LIQUIDS
AND LIQUID SOLUTIONS;" to be as follows: —
This Invention, which is in part a development of that described in the
Specification accompanying my application for Patent No 1985 Dated 23rd January
1884, consists in employing as a medium for filtering, decolorising, and deodorising
liquids or liquid solutions, other than saccharine liquors, the substance known as
Brown Coal, Tertiary Coal, or Lignite, either alone or in admixture with Peat or
vegetable charcoal, or animal charcoal or other filtering, decolorising or deodorising
agents.
In employing this new medium for purifying liquids or liquid solutions generally,
I break up or pulverise the Brown Coal, or the mixture of Brown Coal and other
material, and pack or place it in bulk or in layers in a vessel or chamber of any
convenient form, through which I cause the liquid or liquid solution to pass by
gravitation, by pressure, or by suction, in any of the usual ways. Or I add to, or
mix with, the liquid or liquid solution to be treated, a quantity of the Brown Coal,
or the mixture of Brown Coal and other material, in a broken or pulverulent state,
and drain off the liquid by passing it through a filter formed by packing broken or
pulverulent Brown Coal into a vessel or chamber as above described, or through
filter cloth or filter presses, or through any ordinary porous filtering medium, or by
means of centrifugal hydro-extracters or similar means,

page_text: When by continued use the pores of the Brown Coal have been filled, and it
ceases to act as a good filtering medium, the mass may be charred in a kiln and
used as means for partially purifying liquids or liquid solutions, or it may be used
for fuel, for which it will be particularly adapted when the liquid filtered has been
charged with carbonaceous or oleaginous matters.

I, WALLACE FAIRWEATHER, C.E., of 96 Buchanan Street, Glasgow, in the county
of Lanark, Fellow of the Institute of Patent Agents, do hereby declare the nature
of my said invention for AN IMPROVED FILTERING MEDIUM, AND MODE OF
EMPLOYING THE SAME FOR FILTERING, DECOLORISING AND DEODORISING LIQUIDS
AND LIQUID SOLUTIONS," A communication to me from abroad by Fritz Kleemann
of Schoeningen near Braunschweig in the Empire of Germany, Engineer, and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
וי
This Invention, which is in part a development of that described in the
Specification accompanying my application for patent N° 1985, dated 23rd January
1884, consists in employing as a medium for filtering, decolorising, and deodorising
liquids or liquid solutions, other than saccharine liquors, the substance known as
Brown Coal, Tertiary Coal, or Lignite, either alone or in admixture with Peat or
vegetable charcoal, or animal charcoal, or other filtering, decolorising, or deodorising
agents.
In employing this new medium for purifying liquid solutions generally I break
up or pulverise the Brown Coal, or the mixture of Brown Coal and other material,
and pack or place it in bulk or in layers in a vessel or chamber of any convenient
form, through which I cause the liquid solution to pass by gravitation, by pressure,
or by suction in any of the usual ways. Or I add to, or mix with, the liquid or
liquid solution to be treated, a quantity of the Brown Coal, or the mixture of
Brown Coal and other material, in a broken or pulverulent state, and drain off the
liquid by passing it through a filter formed by packing broken or pulverulent
Brown Coal into a vessel or chamber as above described, or through filter cloth or
filter presses, or through any ordinary porous filtering medium or by means of
centrifugal hydro-extractors or similar means.
When by continued use the pores of the Brown Coal have been filled, and it
ceases to act as a good filtering medium, the mass may be charred in a kiln and
used as means for partially purifying liquids or liquid solutions, or it may be used
for fuel, for which it will be particularly adapted when the liquid filtered has been
charged with carbonaceous or oleaginous matters.

page_text: 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. The employment as a medium for filtering, decolorising, and deodorising
liquids and liquid solutions (other than saccharine liquore) of the substance known
as Brown Coal, Tertiary Coal, or Lignite, substantially as herein set forth.
Second. A filtering, decolorising, and deodorising medium for liquids and liquid
solutions (other than saccharine liquors) consisting of Brown Coal in admixture
with other filtering, decolorising, or deodorising agents, such as peat, vegetable
charcoal, or animal charcoal substantially as herein set forth.
Third. The process or mode of treatment of liquids and liquid solutions (other
than saccharine liquors) which consists in mixing with the liquid a quantity of
Brown Coal, or of Brown Coal in admixture with peat, vegetable charcoal or animal
charcoal or similar filtering, decolorising, and deodorising agent, substantially as
herein set forth.
