PROVISIONAL SPECIFICATION.
Improvements in Treating Floor Dust, House or other Refuse for
Making or Converting it into Fuel.
I, JOHN MAY JAMESON, of Lorraine Villa, Wigston Fields, in the County of
Leicester, Civil Engineer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in treating floor dust, house or other
refuse for making or converting it into fuel.
The object of this invention is to make or convert floor dust, house or other
refuse into fuel for burning either in open fire grates or enclosed furnaces or the
like as a substitute for coal by mixing the dust or refuse after grinding with oil,
grease, or other like fatty or similar substance or substances.
To carry out this invention I take any floor dust, house or other consumable
refuse and pass it through any suitable machine or appliance for pulverizing or
grinding it, or the atoms thereof into powder. I then mix the powder with oil,
grease or other fatty matter or substance to the consistency of a paste suitable
for placing into moulds of any desired shape, or pressed by brick making
machines as now employed, into solid blocks. They are then air or kiln dried
and ready for use. I may also incorporate with the above while in the plastic
state ground charcoal either animal or vegetable.
"
I thus provide a fuel which will burn thoroughly and which will not only be
inexpensive, but which will obviate town refuse in particular from being con-
sumed by the expensive method of providing "destructors now so extensively
employed. It will also save the consumption and take the place of coal not only
in fire grates but in factory marine, railway or other furnaces, besides leaving no
amount of waste to be removed.

page_text: in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This invention relates to improvements in treating floor dust, house or other
refuse for making or converting it into fuel for burning in open fire grates or
enclosed furnaces or the like as a substitute for coal by mixing the dust or refuse
during or after grinding it along with a disinfectant in the form of charcoal; and
oil or the like caloric bituminous and inflammable substance or substances.
The mode of practicing my invention is as follows:-
a
I take any floor dust, house or other refuse that is capable of being consumed
(after the consumable has been sorted away from the non-consumable) and proceed
to place it in a grinding mill of any well known kind such as for instance,
mortar mill," such consumable refuse including rags, paper, cinders, coke, ashes
and the like matter usually found in the refuse from dust bins, ash pits, dust
boxes and the like, the whole of this is taken and put into the mill and the
atoms thereof pulverized or ground into a powder without resorting and sufficient
quantity of charcoal is introduced so as to destroy the smell and act as a disin-
fectant. During the grinding operation oil of any kind, quality or strength is
mixed therewith until the mass assumes the proper consistency; or shall be of
the consistency of paste.
When the mass has been properly mixed and worked well it is put into moulds
to form briquettes, or other analogous shapes.
Briquette machines may also be brought into use if desired.
The moulds after being slightly pressed in a brick press or other well known
machine are carried to the drying ground, and are air or kiln dried when they
are ready for use.
Those intended for house use in open fire grates are made to contain more in-
flammable material, or unctious fluid expressed or drawn from natural, animal
or vegetable substances than those required for slow combustion fuel in closed
furnaces.
The non-consumable material consisting of broken glass, pottery, crockery and
scrap go to make foundations for road and bank or path making.
The other consisting of garbage, bones and the like is collected and passed down.
a shute into a metal tank of the required dimensions or capacity and after
levelling it is covered well over with dust from the sorting sieves or ashes from
the converter furnace and hermetically sealed so that there is no possibility of
smell escaping therefrom, besides reducing the garbage to a proper strength for
distribution on either arable or pasture land as manure after having been ground
in the mill.
The old leather waste found in such refuse can be utilized and made into leather
board, and scrap tin and other metals be conveyed to a furnace for recovery of
the solder and tin or the like therefrom.
In practice I find that the following quantities will produce most satisfactory
results, the block fuel from which will burn thoroughly whether said blocks are
used wholly or broken in pieces, and which will be produced at a small cost.
My desire is more particularly to obviate house or town refuse being consumed
by the expensive method now in use by most corporations of employing and
building "destructors," and entirely do away with the distribution of pestilential
vapours now so freely emitted from such appliances.
I take for example one ton of refuse that is ready for grinding, twelve pounds
or thereabouts (by weight) of charcoal, and six gallons approximately (by
measure) of oil or more or less according to the material under treatment.
It is well known that it has been proposed to use refuse collected from dust
bins, ash pits, dust boxes and the like mechanically sorted for loose fuel involv-
ing an elaborate and continuous process.
Also to mix garbage, refuse and similar materials with sodius oil and chemical
admixtures.

and further with clay and lime, peat and resin.
Also that dust from the streets has been mixed with linseed oil, but broadly I
make no claim to any of these but,
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, declare that what
I claim is:-
The within described process of making or converting the consumable matter
from floor dust, house and other refuse into block fuel by grinding the atoms
thereof to powder and mixing therewith the proper proportion of charcoal for
disinfecting the same and preventing the possibility of smell, and adding thereto
sufficient oil (of any quality or strength,) or unctious fluid expressed or drawn
from natural, animal or vegetable substances that the mass may assume the con-
sistency of paste, which after being more or less pressed in moulds is turned out
and air or kiln dried, substantially as described.
