COAL, PEAT, SHALE, WOOD, AND LIGNEOUS PRODUCTS, AND IN OBTAINING FUEL,
Sealed the 7th April 1865, and dated the 10th October 1864.
PROVISIONAL SPECIFICATION left by the said John Cassell at the
Office of the Commissioners of Patents, with his Petition, on the 10th
October 1864.
I, JOHN CASSELL, of La Belle Sauvage Yard, in the City of London,
Publisher, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN TREATING COAL, PEAT, SHALE, WOOD, AND LIGNEOUS PRODUCTS, AND IN
OBTAINING FUEL, OIL, AND OTHER PRODUCTS THEREFROM," to be as follows:-
My Invention consists in placing the raw products into retorts or ovens
heated from the outside or otherwise in any ordinary manner, according to
the nature of the material acted upon, and I cause to pass through the
material currents of vapour highly charged with electricity generated in what
is known as "Beauregard's apparatus;" or I cause such vapour to come in
contact with the products resulting from distillation of the materials in the

page_text: retorts.
I then condense these products by ordinary means and obtain oils
and other volatile products while the residuum in the retorts is gathered in
the shape of charcoal, coke, and heavy hydrocarbons.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Cassell in the Great Seal Patent Office on the 10th
