AN IMPROVED FUEL
Year: 1872

page_text: LETTERS PATENT to John Jeyes, of Ivy House, Plaistow, in t
County of Essex, for the Invention of "AN IMPROVED FUEL."
PROVISIONAL SPECIFICATION left by the said John Jeyes at the
Office of the Commissioners of Patents, with his Petition, on the
17th May 1872.
I, JOHN JEYES, of Ivy House, Plaistow, in the County of Essex, do
hereby declare the nature of the said Invention for "AN IMPROVED FUEL,"
to be as follows
31
:-
My Invention relates to an inflammable compound made by mixing
one of the products of the distillation of coal tar with a porous or
absorbent material.
In the distillation of coal tar one of the products that comes over is a
substance known commercially as "salt" or creosote which becomes
crystalline or solid when cool.

page_text: In practising my Invention I take this substance and by preference
reduce it to a liquid condition by the application of heat, for which
purpose I place the salt or creosote in a jacket, pan, cr cauldron heated
by steam or any other convenient means. I also take cominon coal
coke, wood charcoal, small coal or coal dust, sawdsust, pent tan, vegetable
fibres, dried peat, wood, or other like porous or absorbent materials. These
materials should be deprived of as much of their moisture as practicable
to increase their absorbent properties, and are then saturated or mixed
with the salt or creosote which, as above specified, I prefer to employ in
a liquid or semi-liquid conditiou, although if desired I may use it in its
solid condition for mixing with some of the abovenamed porous materials.
When small coal, coal dust, or other like material is employed I may add
to the mixture, resin, pitch, tar, or other like substance to make the
mass sufficiently cohesive to be formed into balls or blocks. By these
means I produce an inflammable compound useful for both heating and
lighting but which is chiefly designed to be used as an economical
substitute for ordinary coal or other expensive fuel.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said John Jeyes in the Great Seal Patent Office on
the 16th November 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
JEYES, of Ivy House, Plaistow, in the County of Essex, send greeting.
