I, CATHERINE SARAH COCHRANE, of 66, New Park Road, Brixton
London, S.W., Gentlewoman, do hereby declare the nature of this invention to
be as follows:-
This invention has for its object to provide an improved fuel which will burn
well and throw out very great heat and which is more especially useful for
close stoves, furnaces and the like.
In producing the same I mix one bushel or thereabouts of slack, or sawdust
or both, with two bushels or thereabouts of sand and one and a half bushels or
thereabouts of clay. These substances are mixed well together and then enough
paraffin or other universal oil is added to make the mixture of sufficient con-
sistinary to hold well together when the mass may be formed into blocks or balls
for use.
The oil may be dispensed with and water used in which case they must be set
out in a dry place to harden; when if desired they may afterwards be imersed
in petroleum.

I, CATHERINE SARAH COCHRANE, of 66, New Park Road, Brixton Hill,
London, Gentlewoman, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer
tained in and by the following statement:-
This invention has for its object to provide an improved fuel having good com-
bustible properties and throwing out very great heat, and which is more especially
applicable for use in close stoves, furnaces and the like. According to my
invention in producing or manufacturing the said fuel I mix one bushel, or
thereabouts, of coal slack or sawdust, or both, with two bushels, or thereabouts,
of sand, and one and a half bushels, or thereabouts of dry clay.
After these substances have been well mixed together I then add to the mix-
ture a small quantity of hot pitch, thinned down with crude petroleum, or crude
coal oil, the said quantity being enough to make the mixture of sufficient con-
sistency to hold well together. The mass is then subjected to compression to
form it into blocks or balls for use.

In some cases the oil may be dispensed with and water used instead, in which
case the blocks, after they have been formed, must be set out in a dry place to
harden, when if desired they may afterwards be immersed in petroleum.
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:
(1) The improved fuel comprising a mixture of coal slack or sawdust, or both,
sand, and dry clay, to which is added hot pitch, crude petroleum or crude coal
oil substantially as described.
(2) In an improved fuel for close stoves, furnaces, and the like, the combi-
nation of one part of coal slack, or sawdust, or both, two parts of sand, and one
and a half part of dry clay well mixed together, and a small quantity of hot
pitch, thinned down with crude petroleum or crude coal oil, or water, and added
to the mixture to bind or hold the same together, the resulting mass being com-
pressed to form it into blocks or balls substantially as described.
Dated this 16th day of March 1900.
