page_text: PROVISIONAL SPECIFICATION left by William Lloyd Wise at the
Office of the Commissioners of Patents, with his Petition, on the
9th June 1869.-A communication from abroad by Messieurs
Buesnel, Le Quesne, and Dumontier, of St. Servan, in the French
Empire.
I, WILLIAM LLOYD WISE, of Chandos Chambers, Adelphi, in the City
of Westminster, Consulting Engineer and Patent Agent, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN THE MANU-
FACTURE OF ARTIFICIAL FUEL, AND IN APPARATUS FOR THE PURPOSE," to be as
follows:-
This Invention consists in distilling mineral and vegetable tars and
combining their residual products with coal dust to form "rocky"
masses of fuel without pression, and in the apparatus for that purpose.
In the following description of the said Invention, as communicated
to me by my foreign correspondents, reference is made to the accom...
panying Drawings, which form a part of this Provisional Specification..
In a reservoir (A) filled with mineral or vegetable tar is immersed the
lower part of a pump, marked B, which raises the tar and feeds it into
the boiler or retort C through the manhole D, which is afterwards closed
by means of a valve Z. This boiler is placed horizontally and is heated
by the fire F, whose smoke escapes by the chimney G.. The vapour

off by the hole E and tube T and descends through a spiral refrigerator U
coiled in the interior of a cylinder V, where it is transformed into nap-
thaline, paraffine, or benzine, according to the degree of heat, and the
residues which are too heavy fall into a little reservoir X, from whence
they return to A by the subterraneous tube Y. This operation being
completed the residual products of the tar remain at the bottom of
the boiler C, thence they pass by the tube H to the cock I, which
is provided with a key J actuated by means of the handle K, whose
fulcrum is at the side (M) of a mixing apparatus which is pro-
vided with a hinged cover N. Immediately the cook is opened the
residual products from the boiler are precipitated into the cylinder of
the mixing apparatus, which is previously supplied with a certain
quantity of coal, and the cock is re-closed by raising the handle as soon
as it has been ascertained (by raising the lid slightly) that a sufficient
quantity of liquid has been introduced. The mixing of the coal dust and
residual products is then effected by means of the mixing apparatus,
which is constructed with a square iron rod sliding on a vertical shaft
and carrying four vertical branches O. A horizontal shaft situated above
the cylinder is provided at one of its extremities with a fly wheel P
having a handle, and at its other end the shaft itself is furnished with
another handle, as shewn. In the centre is fixed a pinion L gearing into
a toothed wheel L' fixed upon the end of the vertical shaft in the interior
of the cylinder, and by turning the handles rotary motion is communi-
cated to the four vertical branches which are so arranged that no two of
them travel in the same line. The cylinder M, which contains all the
mixing apparatus, is set over a furnace R, the products of combustion
from which pass along the channel S situated at the outer side of the
cylinder, and which corresponds with the sheet-iron channel or passage
I leading from the interior to the uptake or chimney G..
The operations described having been effected the door a at the side of
the cylinder below the handle of the key of the cock is opened and the
mixture leaves in the state of paste, and it is then cooled by the air into
'rocky" masses or lumps of fuel.
