Improvements in the Utilization of Breeze, Dust, and Cinder
Waste, more Especially the Dust or Waste Collected from
Dwellinghouses.
1, WILLIAM HENRY LINDSAY of 14 South Wharf, Paddington in the County of
Middlesex Engineer do hereby declare the nature of this invention to be as
follows:-
At the present time the dust and cinders collected from dwellinghouses and the
waste dust of coke known as breeze is used chiefly in the burning of bricks and as
the uses to which it can be advantageously applied have hitherto been few the price
at which such waste material can be obtained is extremely low.
I utilize the waste by manufacturing it into blocks of fuel which are well adapted
for being burnt in the fire places of kitchen ranges or in other similar closed fire
places but which can also be used for burning in open fire places if desired. To
inake the waste into blocks of fuel I admix with it about one third of coal dust or
powdered coal the more bituminous the better and then mould such mixture into
solid blocks of a size suitable for being placed on to a fire. To mould the mixture
into blocks I preferably cause it to pass through a tube heated externally and keep it
agitated as it passes through the tube. In this way the mixture becomes highly
heated and incorporated together and as it passes from the end of the tube I mould
it into blocks by a powerful press as described in an application for Patent previously
lodged by me No. 13922 in the year 1886. I also in some cases admix a small
percentage of sugar with the mixture as described in an application for. Patent made
by me No. 168487
Or in place of manufacturing the mixture into blocks by the above mentioned
means I may mould into blocks in the manner described in the Specification of a
Patent granted to me No. 13985 in the year 1886.

Improvements in the Utilization of Breeze, Dust, and Cinder
Waste, more Especially the Dust or Waste Collected from
Dwellinghouses.
1, WILLIAM HENRY LINDSAY of 14 South Wharf, Paddington in the County of
Middlesex, Engineer 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 :-
At the present time the dust and cinders collected from dwellinghouses and the
waste dust of coke known as breeze is used chiefly in the burning of bricks and as
the uses to which it can be advantageously applied have hitherto been few the price
at which such waste material can be obtained is extremely low.
I utilize the waste by manufacturing it into blocks of fuel which are well adapted
for being burnt in the fire places of kitchen ranges or in other similar closed fire
places but which can also be used for burning in open fire places if desired. To
make the waste into blocks of fuel admix with it about one third of coal dust or
powdered coal the more bituminous the better and then mould such mixture into solid
blocks of a size suitable for being placed on to a fire. To mould the mixture into
blocks I preferably cause it to pass through a tube heated externally and keep it
agitated as it passes through the tube. In this way the mixture becomes highly
heated and incorporated together and as it passes from the end of the tube I mould it
into blocks by a powerful press as described in the specification of a Patent previously
lodged by me No. 13922 in the year 1886. I also in some cases admix a small per-
centage of sugar with the mixture as described in an application for Patent made by
me No. 168-187
Or in place of manufacturing the mixture into blocks by the above mentioned means
I may mould into blocks in the manner described in the Specification of a Patent
granted to me No. 13985 in the year 1886.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is: :-
1. The manufacture of coke dust into blocks of fuel by admixing it with bituminous
coal and compressing it into blocks substantially as described.
2. The manufacture of cinder waste as collected froin dwelling houses into blocks
of fuel by admixing it with bituminous coal and compressing it into blocks
substantially as described.
