Year: 1875

page_text: LETTERS PATENT to Thomas Henry Baker, of No. 5, Penny Fields,
West India Road, Poplar, and Daniel Walker Forbes, of the
Smithfield Works, New Road, Blackwall, both in the County of
Middlesex, Engineers, for the Invention of "IMPROVEMENTS IN MEANS
OR APPARATUS FOR FACILITATING THE DRYING OF HOPS, MALT, AND OTHER
GRAIN, WHICH IMPROVEMENTS ARE ALSO APPLICABLE TO THE DRYING OF OTHER
MATTERS OR MATERIAL."
Scaled the 28th January 1876, and dated the 5th August 1875.
PROVISIONAL SPECIFICATION left by the said Thomas Henry Baker
and Daniel Walker Forbes at the Office of the Commissioners of
Patents, with their Petition, on the 5th August 1875.
We, THOMAS HENRY BAKER, of No. 5, Penny Fields, West India
Road, Poplar, and DANIEL WALKER FORBES, of the Smithfield Works,
New Road, Blackwall, both in the County of Middlesex, Engineers, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MEANS OR APPARATUS FOR FACILITATING THE DRYING OF HOPS, MALT, AND OTHER
GRAIN, WHICH IMPROVEMENTS ARE ALSO APPLICABLE TO THE DRYING OF OTHER
MATTERS OR MATERIAL," to be as follows:-
In effecting our improvements we form the fire-bars of the boiler

page_text: furnace hollow for the passage of air to a hot air chamber, and which
air becomes heated in such passage.
We also apply other air passages in and about the furnace chamber
for the purpose of heating air to supply such hot air chamber.
The heated air in the hot air chamber is by means of a fan or other
suitable forcing means forced through suitable passages to outlets which
are kept revolving, so as to distribute the heated air as uniformly as
possible in a chamber under the floor or support of the matters to be
acted upon by such heated air. Or instead of employing a hot air
chamber we in some cases force the air into and through the air
passages, where it is heated, and thence passes into the chamber under
the floor or support of the matters to be acted upon.
To facilitate the action of the heated air on hops and other matters
which have become caked or adhered together we place such matters on
another chamber or portion of the said chamber and apply over such
matters a shield or cover. The part on which the matters rest is per-
forated, and there is an opening or chamber beneath the shield or cover,
and the direction of these perforations or openings is such as to facilitate
the action of a jet of steam to act upon the matters thus massed together
for the purpose of separating the parts thereof and driving them on to
the drying floor. Elastic or other holding means serve to steady the
pocket or other pile of matters whilst being thus acted upon, and
also to keep open a space between them and the shield or cover for the
better action of the current of steam.

SPECIFICATION in pursuance of the conditions of the Letters Patent, 2
filed by the said Thomas Henry Baker and Daniel Walker Forbes
in the Great Seal Patent Office on the 5th February 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
HENRY BAKER, of No. 5, Penny Fields, West India Road, Poplar, and
DANIEL WALKER FORBES, of the Smithfield Works, New Road, Black- 30
wall, both in the County of Middlesex, Engineers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifth day of August, in the year of

page_text: our Lord One thousand eight hundred and seventy-five, in the thirty-
ninth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Thomas Henry Baker, and Daniel
Walker Forbes, Her special license that we, the said Thomas Henry
Baker and Daniel Walker Forbes, our executors, administrators, and
assigns, or such others as we, the said Thomas Henry Baker and
Daniel Walker Forbes, our 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 Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for “IMPROVEMENTS IN MEANS OR APPARATUS FOR
FACILITATING THE DRYING OF HOPS, MALT, AND OTHER GRAIN, WHICH IMPROVE-
MENTS ARE ALSO APPLICABLE TO THE DRYING OF OTHER MATTERS OR MATERIAL,"
upon the condition (amongst others) that we, the said Thomas Henry
Baker and Daniel Walker Forbes, our executors or administrators, by
an instrument in writing under our or their hands and seals, or under
the hand and scal of one of us or them, 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Thomas Henry Baker and Daniel
Walker Forbes, 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,
that is to say :-
In effecting the first part of our improvements we form the fire-bars
of the boiler furnace hollow for the passage of air to a hot air chamber,
and which air becomes heated in such passage.
We also apply other air passages in and about the furnace chamber
for the purpose of heating air to supply such hot air chamber.
The heated air in the hot air chamber is by means of a fan or other
suitable forcing means forced through suitable passages to outlets which
are kept revolving, so as to distribute the heated air as uniformly as
possible in a chamber under the floor or support of the matters to be
acted upon by such heated air. Or instead of employing a hot air

page_text: Having thus described our Invention, and means which we adopt
in carrying the same into effect, we would have it understood that what
we claim is,-
First. The arranging or combining parts whereby air may be heated,
and such heated air utilized for the purpose of facilitating the
drying of hops, malt, or other grain, or other matters, or material, as
described.
Secondly. We claim the arranging or combining parts whereby the
action of the heated air on hops or other matters which have become
caked or adhered together may be facilitated by the action of jets of
steam as described.
In witness whereof, we, the said Thomas Henry Baker and Daniel
Walker Forbes, have hereunto set our hands and seals, this
Fifth day of February, in the year of our Lord One thousand
eight hundred and seventy-six.
