PROVISIONAL SPECIFICATION left by John Fordham Stanford at the
Office of the Commissioners of Patents, with his Petition, on the
8th July 1858.
I, JOHN FORDHAM STANFORD, of Howard Street, in the Parish of Saint
Clement Danes, in the County of Middlesex, Engineer, do hereby declare
the nature of the said Invention of "A NEW AND IMPROVED METHOD OF AND
APPARATUS FOR APPLYING HEATED AIR IN DRYING CORN, HAY, AND OTHER LIKE
ARTICLES, IN THE STACK OR OTHERWISE, AND IN DRYING GOODS, AND IN HEATING
AND DRYING ROOMS AND BUILDINGS," to be as follows:-
I accomplish my said Invention by means of a stove, and certain appliances
connected therewith, as herein-after mentioned. The said stove to be cir-
cular, polygonal, or square, and of such dimensions and substance as may be
desired, and to consist of a cylinder placed vertically, with an open-framed
rim inside, at the foot or lower portion thereof, to support an inner cylinder
and a grate; I then have a secoitd smaller cylinder within the first, to rest
upon the rim fixed for the grate, but leaving a space of about one-sixth of the
diameter of the outer cylinder, between the inner cylinder and the outer
cylinder, as an air chamber. The grate is placed inside the inner cylinder
upon the rim prepared for that purpose, and the inner cylinder is perforated
to allow the burnt air which passes through the fire in the grate to pass into
the space between the cylinders. To supply fuel, the inner cylinder is pro-

page_text: vided at the top with a neck or feeding pipe about four inches in height, which
passes through the outer cover of the larger cylinder. The neck or feeding
pipe is then secured with a close-fitting moveable cover, to fit into the aperture.
And I also construct this apparatus with one cylinder ouly; in such case the
grate is of the size to fit the cylinder; doors to be made into the cylinders
for lighting the fires, &c.; the cylinder to be supported with legs. A pipe
or flue to be attached to the outer cylinder, by which the hot air is drawn off,
and then by means of a fan blower fitted within said pipe or flue forced among
the corn, hay, or other goods required to be dried, or into any chamber or
other place to be dried or heated, such blower to be of the ordinary kind, but
fitted inside said pipe by having that portion of said flue or pipe occupied by
it enlarged for the purpose. The fan blower to be of the width of the flue,
and of the required diameter. The flue or pipe to be continued on and other
portions perforated, and terminating with a moveable tapered end for dis-
tributing the heated air, to be added at pleasure. The pipe and blower to
be supported with a leg or legs, as the case may require. The whole of these
apparata to be made of iron, or other suitable material. The stove may
either be bedded and stationary, in the ordinary way, or fitted to a suitable
moveable carriage.
