New or Improved Compounds to be Used for Deodorising, Filtering,
and Manuring Purposes.
I, THOMAS MCMURRAY, of 44 Jamiaca Street, Glasgow, Lanarkshire, Manufacturing
Chemist, do hereby declare the nature of my invention to be as follows:-
My Invention comprises the preparation of new or improved compounds, and their
use for deodorising, filtering, manuring, and such like purposes, and which will be
especially valuable as a base or retainer of products for manure.
According to my Invention I take furnace slag, and mix it with carbon or charcoal
and chemical re-agents to form a new compound.
In carrying my said Invention into practice, I run the slag hot from the blast
furnace into a solution of sulphuric or other acid, and water, preferably about one
part concentrated acid to four or five parts of water, which has the effect of separating
the slag into a powdered or granular state, thus saving the necessity for grinding or
reducing the mixture.
I take vegetable carbon or charcoal of wood, peat, coal or shale, from the retort
and place it in an air-tight receiver until it cools.
I then take these mixtures preferably in the proportion of two or three parts of the
carbon or charcoal to each part of the solutionised or prepared slag with as much of
the acidified solution as it will carry, and thoroughly mix them together, preferably
in a pan, pug or other mill, which would cause the carbon to absorb the acidified
solution, and reduce the mixture to a granular dry or semi-dry state.
The carbon and the slag may each be treated with the acid solutions separately,
before being mixed together to form the combined compound as above stated.
This new or improved compound could be used as a manure for land as thus
prepared, but its chief use would be as a deodoriser for distributing in a powdered
state over the floors of stables, byres, yards, and other places where animals are kept,
and dung heaps where decayed matter is collected to form manure, and into privies,
urinals, dry-closets, and other places, for the free acid in the compound to absorb and
fix the ammonia and other valuable products in the animal urine and excrement, to
be used for manure purposes, the charcoal and calcium silicate of the compound also
...

for these places or apartments to keep them sweet and the animals healthy, and
improve the sanitary condition of the atmosphere and places.
My new compounds can also be used for filtering and deodorising the waste liquors
from chemical and other public works, and recovering the valuable bye-products
therefrom; and in such cases I mix with my compounds other acids, alkalies, or
other chemical substances, that will neutralise or destroy the noxious gases or
impurities arising from or given off by these waste liquors.

I THOMAS MCMURRAY, of 44 Jamiaca Street, Glasgow, Lanarkshire, Manufacturing
Chemist, do hereby declare the nature of my Invention, and in what manner the same
is to be performed to be particularly described and ascertained in and by the
following statement in writing that is to say :-
My said Invention comprises the preparation of new or improved compounds, and
their use for deodorising, filtering, manuring and such like purposes, and which will
be especially valuable as a base or retainer of products for manure.
According to my invention I take furnace slag, and mix it with carbon or charcoal
and chemical re-agents to form a new compound.
, And in order that the nature and novelty of my said invention and the manner of
performing or carrying the same into effect or practice may be properly understood
I shall now proceed to describe the same in and by the following statement in
writing. In carrying my said invention into practice, I run the slag hot from the
blast furnace into tanks or vessels containing a solution of sulphuric or other acid and
water, preferably about one part concentrated acid to four or five parts of water, or I
can first run the hot slag into tanks of water alone and afterwards mix and treat it
with a solution of sulphuric or other acid, and which has the effect of separating the
slag into a powdered or granular state, thus saving the necessity for grinding or
reducing the mixture.
I take vegetable carbon or charcoal of wood, peat, coal or shale from the retort
and place it in an air-tight receiver until it cools. I then take these mixtures
preferably in the proportion of two or three parts of the carbon or charcoal to each
part of the solutionised or prepared slag or silicate with as much of the acidified
solution as it will carry and thoroughly mix them together, preferably in a pan, pug
or other mill which causes the carbon to absorb the acidified solution, and reduces the
mixture to a granular dry or semi-dry state.
The carbon and the slag may each be treated with the acid solutions separately,
before being mixed together to form the combined compound as above stated.
This new or improved compound is to be used as a manure for land as thus
prepared, but its chief use is as a deodoriser for distributing in a powdered state over
the floors of stables, byres, yards, and other places where animals are kept, and dung
heaps where decayed matter is collected to form nanure, and into privies, urinals,
dry-closets and other places, for the free acid in the compound to absorb and fix the
ammonia and other valuable products in the animal urine and excrement, to be used
for manure purposes, the charcoal and calcium silicate of the compound also forming
a valuable part of the manure. This new compound also acts as a deodoriser for
these places or apartments to keep them sweet and the animals healthy, and improve
the sanitary condition of the atmosphere and places.

page_text: My new compounds can also be used for filtering and deodorising the waste liquors
from chemical and other public works, and recovering the valuable bye-products
therefrom and in such cases I mix with my compounds other well-known acids,
alkalies, or other chemical substances, that will neutralise or destroy the noxious
gases or impurities arising from or given off by these waste liquors, according to the
nature of the impurities they contain.
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. Compounds composed of furnace slag or silicate, carbon or charcoal, and
dilute acids or chemical reagents, for deodorising, filtering, and manuring purposes,
substantially as herein described.
Second. In the preparation of compounds to be used for deodorising, filtering, and
manuring purposes the use of furnaced acidified slag or silicate in combination with
carbon or charcoal, substantially as herein described.
Third. The herein described process or mode and means of preparing compounds to
be used for deodorising filtering and manuring purposes, consisting in treating
furnace slag or silicate with acidified solution, and then combining or mixing same
with carbon or charcoal in a pan, pug, or other mill to reduce the mixture or
compound to a granular dry or semi-dry state, substantially as set forth.
