page_text: LETTERS PATENT to Henry Gould Gibson, of Mark Lane, in the City
of London, Merchant, for the Invention of "IMPROVEMENTS IN APPARATUSES
FOR DRYING HOPS, MALT, GRAIN, AND OTHER VEGETABLE SUBSTANCES, PART
OF WHICH IS APPLICABLE AS A FAN OR BLOWER."-A communication from
abroad by Joseph Perrigault, of Rennes, France.
Sealed the 6th May, 1862, and dated the 7th November, 1861.
PROVISIONAL SPECIFICATION left by the said Henry Gould Gibson at
the Office of the Commissioners of Patents, with his Petition, on the
7th November 1861.
I, HENRY GOULD GIBSON, of Mark Lane, in the City of London, Merchant,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
APPARATUSES FOR DRYING HOPS, MALT, GRAIN, AND OTHER VEGETABLE SUBSTANCES
PART OF WHICH IS APPLICABLE AS A FAN OR BLOWER," (communicated to me from
abroad by Joseph Perrigault, of Rennes, France), to be as follows:-
My Invention consists, first, of a box or case surrounded with single or
double jackets or envelopes, and containing inside, at different levels, two,
three, or more shelves or tables, either formed of perforated louvre plates,
which are acted upon by a rod or lever, or they are formed of perforated or
openwork plates. These shelves or tables run upon slides inside the case to
allow of their being withdrawn through doors fitted for the purpose. At the
lower part of the case a funnel or shoot is fixed, through which the articles
can be withdrawn. At the upper part and side of the case a hopper may be
fixed, through which the articles may be fed on to the upper shelf, and from it
to those below it.
Second, of a fan or blower placed at the upper part of the case, constructed
in the manner shown in the accompanying Drawing, where G, H, represent
.

page_text: two discs, one full, the other formed with an eye O, P, for the admission of air
into the fan. The discs are separated by blades, at least twelve in number,
fixed to the two discs. The blades are each composed of three sides or plates
IK, IJ, JK, and are arranged in manner to form outlets s, s, extending
from the eye to the periphery of the discs. The passages forming the outlets
are rather less at the periphery than at the eye of the apparatus. The fan
draws continuously the air contained in the case and admitted into it, as here-
after explained,and drives it out into a tube,passage.or conduit communicating
with the external atmosphere. This fan is applicable for all purposes where
fans or blowers are or may be used.
Third, of a stove, surrounded or not with brickwork, communicating with
the exterior of the building by a pipe placed above it; in this pipe there is a
valve for preventing, when necessary, all escape of heat through it. From the
side and upper part of the stove a pipe is carried into the lower part of the
case or box first mentioned, through which air is supplied as fast as it is
drawn in by the fan. This pipe is of the particular form following:- It is
cylindrical, but bulgedout for a portionof its length; a correspondinglybulged
ring is fitted inside the bulged part, and the ring and bulged portion of the
pipe are formed with slots or apertures, which may be made to correspond or
not, in order to admit or shut off the admission of cold air into the pipe to mix
with the heated air in it. I sometimes fit a prism inside the pipe to divide
the air. A thermometer is fixed in the pipe near its entrance into the box or
case; there is also a valve for the purpose of regulating the admission of air
into the box. Wire gauze screens may be placed in the pipe to prevent
the entrance of flame into the box, which might otherwise be drawn in by
the fan.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry Gould Gibson in the Great Seal Patent Office on the
7th May 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY

Henry Gould Gibson, my executors, administrators, 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 Britainand Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
APPARATUSES FOR DRYING HOPS. MALT, GRAIN. AND OTHER VEGETABLE SUBSTANCES
PART OF WHICH IS APPLICABLE AS A FAN OR BLOWER," (communicated to me from
abroad by Joseph Perrigault, of Rennes, France), upon the condition (amongst
others) that I,the said Henry Gould Gibson, iny exécutors or administrators,
by an instrument in writing under my, or their, or one of their hands and
seal,should particularly describe and ascertain the nature of the said Inven-
tion, and in what manner the same was to be performed, and cause the same

T
NOW KNOW YE, that I, the said Henry Gould Gibson, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement thereof, reference being had to the accompanying Drawing, that
is to say:
My Invention consists, first, of a box or case surrounded with single or
double jackets or envelopes, and containing inside, at different levels, two,
three, or more shelves or tables, either formed of perforated louvre plates,
which are acted upon by a rod or lever, or they are formed of perforated or
openwork plates. These shelves or tables run upon slides inside the case,
to allow of their being withdrawn through doors fitted for the purpose. At
the lower part of the case a funnel or shoot is fixed, through which the
articles can be withdrawn. At the upper part and side of the case a hopper
may be fixed, through which the articles may be fed on to the upper shelf,
and from it to those below it.
Second, of a fan or blower placed at the upper part of the case, con-
structed in the manner shewn in the accompanying Drawing, where G, H,
represent two discs, one full, the other formed with an eye O, P, for the ad-
mission of air into 'the'fan. The discs are separated by blades, at least
twelve in number, fixed to the two discs. The blades are each composed
of three sides or plates IK, IJ, J K, and are arranged in manner to form
outlets s, », extending from the eye to the periphery of the discs. The
passages forming the outlets are rather less at the periphery than at the

page_text: eye of the apparatus. The fan draws continuously the air contained in the
case, and admitted into it, as hereafter explained, and drives it out into a
tube, passage, or conduit communicating with the external atmosphere. This
fan is applicable for all purposes where fans or blowers are or may be used.
Third, of a stove, surrounded or not with brickwork, communicating with
the exterior of the building by a pipe placed above it; in this pipe there is a
valve for preventing, when necessary, all escape of heat through it. From the
side and upper part of the stove a pipe is carried into the lower part of the
case or box first mentioned, through which air is supplied as fast as it is drawn
in by the fan. This pipe is of the particular form foilowing:-It is cylindrical
but bulged out for a portion of its length, a correspondingly bulged ring is
fitted inside the bulged part, and the ring and bulged portion of the pipe are
formed with slots or apertures, which may be made to correspond, or not, in
order to admit or shut off cold air into or from the pipe to mix with the heated
air in it. I sometimes fit a prism inside the pipe, to divide the air. A thermo-
meter is fixed in the pipe near its entrance into the box or case, there is
also a valve for the purpose of regulating the admission of air into the box.
Wire gauze screens may be placed in the pipe to prevent the entrance of
flame into the box, which might otherwise be drawn in by the fan.
And having now described the nature of the said Invention, and in what
manner the same is to be performed, I declare that I claim as the improve-
ments in apparatuses for drying hops, malt, grain, and other vegetable
substances, part of which is applicable as a fan or blower,-
First, the construction and arrangement of the box or case with per-
forated plates, herein-before described.
Second, the construction of the fan or blower herein-before described
and represented in the accompanying Drawing, whether such fan be used
in the drying of vegetable substances or, otherwise.
And, third, the construction of the stove, and parts connected there-
with, arranged and acting in manner herein-before described.
In witness whereof, I, the said Henry Gould Gibson, have hereunto set
my hand and seal, this Seventh day of May, One thousand eight
hundred and sixty-two.
HENRY G. GIBSON. (L.S.)
