Year: 1863

page_text: LETTERS PATENT to Bernard James Webber, of Newton Abbot, in the
County of Devon, for the Invention of "IMPROVEMENTS IN THRESHING
MACHINES."
Sealed the 8th March 1868, and dated the 16th September 1863.
PROVISIONAL SPECIFICATION left by the said Bernard James Webber
at the Office of the Commissioners of Patents, with his Petition, on the
16th September 1863.
I, BERNARD JAMES WEBBER, of Newton Abbot, in the County of Devon,
do hereby declare the nature of the Invention for "IMPROVEMENTS IN
THRESHING MACHINES," to be as follows:-
This Invention has for its object improvements in threshing machines, and
consists in making and fixing a receiver, being a sheet of iron or zinc, or other
suitable material underneath the riddle of a threshing machine to catch the
grain and chaff which passes through the riddle; this receiver has an
aperture through which the chaff and corn passes on to ordinary or other
winnowing sieves or screens, and is there subjected to a blast from the side.
The receiver with the frame for the sieves and screens fastened to it is attached
to the riddle board, or to the frame, or other supports of it, and is moved by the
same motion conjointly with the riddle.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Bernard James Webber in the Great Seal Patent Office
on the 16th March 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BERNARD
JAMES WEBBER, of Newton Abbott, in the County of Devon, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of September, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-seventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Bernard James Webber, Her special licence that I, the said
Bernard James Webber, my executors, administrators, and assigns, or such
others as I, the said Bernard James Webber, 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 Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "IMPROVEMENTS IN THRESHING MACHINES," upon the condition
(amongst others) that I, the said Bernard James Webber, 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 Bernard James Webber, 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 :-
The object of this Invention is to simplify the construction of combined
threshing machines, and it consists in applying a receiver of wood, iron, or
.other suitable material underneath the ordinary or other riddle of a threshing
machine, and attached to it or to the frame of it so that the receiver may be
moved conjointly therewith; this receiver is either convex with one or
more holes at the lowest part, or angular with a flat bottom fixed obliquely, or
of two or more pieces fixed so that the corn and chaff falling into it through
the riddle is brought to the holes or openings through which it falls on to an
ordinary set of winnowing or other sieves or screens, and is subject to currents
of air from the air trunk at the bottom of the air channel which blows the

page_text: chaff and refuse from the corn, and in the mode of regulating the air currents
by means of a slide or slides fitted into grooves in the air trunk at required
acute angles, each having a set screw at the outer side with which to regulate
the required supply of air, and each port having a fixed air guide under or
over each slide to conduct the air to the sieve or screen through which it is
chaff and refuse from the corn, and in the mode of regulating the air currents
by means of a slide or slides fitted into grooves in the air trunk at required
acute angles, each having a set screw at the outer side with which to regulate
the required supply of air, and each port having a fixed air guide under or
over each slide to conduct the air to the sieve or screen through which it is
required to operate.
DESCRIPTION OF THE DRAWING.
A, fan or blower; B, air channel; B', port from air chest; D, receiver;
E, aperture of receiver; B³, port from air chest; B³, port from air chest ;
B*, port from air chest; 1, 2, 3, air guides to shift by the screws at back as
required; 0, 0, 0, fixed air guide; I, bottom screen; C, riddle as used to
ordinary threshing machines.
Having thus described the nature of the said Invention, and the manner
in which the same is to be performed, I wish it to be understood that I
claim the combination of receiver and screen so fixed with the side blast and
its appliances.
In witness whereof, I, the said Bernard James Webber, have hereunto
set my hand and seal, this Tenth day of March, in the year of our
Lord One thousand eight hundred and sixty-four.
BERNARD JAMES WEBBER. (L.S.)
