Sealed the 29th August 1873, and dated the 11th June 1873.
PROVISIONAL SPECIFICATION left by the said José Guenard at the
Office of the Commissioners of Patents, with his Petition, on the
11th June 1873.
I, JOSÉ GUENARD, of Mayaguez, in the Island of Porto Rico, a Colony
of Spain, Merchant, at present residing at Birmingham, in the County
of Warwick, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINERY FOR DRYING COFFEE AND GRAIN," to be as
follows, that is to say :—
My Invention consists in forming a revolving drum having an outer
perforated cylinder made of galvanized sheet iron or other suitable metal,
or of woven wire. Inside this cylinder is secured a second perforated
cylinder of smaller diameter, the ends of the cylinders being closed by

page_text: metal discs. A jacket or space is thus left between the two cylinders,
the space in the inner cylinder also forming a chamber.
The revolving drum works upon two bars with four rollers, or it is
mounted in bearings or on an axle in a suitable framework so as to be
capable of revolving horizontally, having suitable driving gear worked t
by hand or other power.
The coffee or grain to be dried is put into the jacket or space between
the cylinders of the drum through a door or lid; artificial heat or hot
air is then introduced into the chamber of the inner cylinder and through
the perforations of the inner cylinder to the coffee or grain whilst it is in 1
motion by the revolution of the machine, such hot air afterwards
escaping through the perforations in the outer cylinder.
When the drum is mounted upon two bars with four rollers the heat
is introduced to the chamber of the inner cylinder through the centre of
either end from a pipe or by other convenient means, but when the 1
drum is mounted in bearings or upon an axle the heat is introduced at
any suitable point in either end, formed by a metal disc secured to the
framework, and fitting within an annular collar, flange, or rim formed
in the end of the drum, or the hot air may pass into the heating chamber
through the axle, which is hollow for such purpose, with holes upon its 2
circumference.
The cylinders of the drum may be circular, octagonal, or other suitable
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said José Guenard in the Great Seal Patent Office on
the 10th December 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSÉ
GUENARD, of Mayaguez, in the Island of Porto Rico, a Colony of Spain,
Merchant, at present residing at Birmingham, in the County of Warwick,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eleventh day of June, in the year
of our Lord One thousand eight hundred and seventy-three, in the thirty

page_text: sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said José Guenard, Her special license that
I, the said José Guenard, my executors, administrators, and assigns, or
such others as I, the said José Guenard, my executors, administrators,
5 and assigns, should at any time agree with, and no others, from time to
time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the
United Kingdom of Great Britain and Ireland, the Channel Islands, and
Isle of Man, an Invention for "IMPROVEMENTS IN MACHINERY FOR DRYING
COFFEE AND GRAIN," upon the condition (amongst others) that I, the
said José Guenard, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said José Guenard, do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement, reference being had to the Drawings hereunto
annexed, and to the letters and figures marked thereupon, that is to
say :-
Figure 1 is a front elevation, and Figures 2 and 3 are side elevations
of my improved machinery for drying coffee and grain, and it consists
of a revolving drum (a) having an outer perforated cylinder (6) made of
galvanized sheet iron or other suitable metal or of woven wire. Inside
this cylinder (6) is secured a second perforated cylinder (c) of smaller
diameter, the ends of the cylinders being closed by metaldiscs (d) (àª³). A
jacket or space (e) is thus left between the two cylinders, the spac (ƒ)
in the inner cylinder also forming a chamber.
The revolving drum (a) works upon two bars with four rollers, or it is
mounted as shewn in bearings (9) with or without the through axle (h)
in the framework (i) so as to be capable of revolving horizontally,
having suitable driving gear (k) worked by hand or other power.
The coffee or grain to be dried is put into the jacket or space (e)
between the cylinders (b) and (c) through a suitable door or lid (1).
Artificial heat or hot air is then introduced into the chamber (f) of the

page_text: inner cylinder and through the perforations of the inner cylinder (c) to
the coffee or grain whilst it is in motion by the revolution of the
machine, such hot air afterwards escaping through the perforations in
the outer cylinder.
means,
When the drum (a) is mounted upon the two bars with four rollers
the heat is introduced to the chamber (f) of the inner cylinder (c)
through the centre of either end from a pipe or by other convenient
but when the drum (a) is mounted in bearings as shewn the
heat is introduced at any suitable point, as at (m) Figure 3, in either
end formed by a metal disc (d) secured to the framework (i) and fitting
within an annular collar, flange, or rim formed in the end of the drum (a),
or the hot air may pass into the heating chamber through the axle (h),
which is hollow for such purpose, with holes upon its circumference.
The cylinders of the drum may be circular, octagonal, or other suitable
shape in cross section as desired.
Having thus described the object and nature of my said Invention,
and the manner in which the same is to be carried into effect, I claim,
without limiting myself to these; cietails, the several improve-
ments in machinery for drying coffee and grain, substantially in manner
as herein more fully set forth and specified.
In witness whereof, I, the said José Guenard, have hereunto set my
hand and seal, this Twenty-first day of June, in the year of our
Lord One thousand eight hundred and seventy-three.
