Year: 1864

page_text: LETTERS PATENT to Charles James Newbolt, of Millbrook, near Southamp-
ton, Engineer, for the Invention of "IMPROVEMENTS IN THE ARRANGEMENTS
AND CONSTRUCTION OF FIXED AND PORTABLE COMBINED THRASHING MACHINES."
Sealed the 27th January 1865, and dated the 10th September 1864.
PROVISIONAL SPECIFICATION left by the said Charles James Newbolt
at the Office of the Commissioners of Patents, with his Petition, on the
10th September 1864.
I, C LES JAMES NEWBOLT, of Millbrook, near Southampton, Engineer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
ARRANGEMENTS AND CONSTRUCTION OF FIXED AND PORTABLE COMBINED THRASHING
MACHINES," to be as follows:-
This Invention has for its object improvements in thrashing machines.
The shakers with the vibrating boards are usually driven by separate cranks
or excentrics. Now, according to my Invention, I intend driving with only
one. The one driving the shakers, for reference, I shall call the first crank,
the other, driving the vibrating boards, the second crank.
I dispense with this second crank and drive the vibrating boards in the
following manner :-I strengthen the shakers by means of stay rods coming
from the under side of the driving block to the under side of one end of the
shaker, bolt it there, let it continue on with a joint or notch intervening to
the vibrating board, then bolt again, that the board is driven by the same
Die 81

page_text: crank as the shakers; the shakers being held at the same time by the rods
that is driving the board, and so both go together, vice versa for the other
board or trough; at the other end of the machine, half the rods and blocks
are connected to one, half to the other, or the rods may be put so as to have
no connection to the shakers after leaving the crank or driving block.
Rods of any description may be used, either flexible or jointed.
The corn elevator, barley horner, cleanser, and second blowing machine.
-This is all done together by a scrow inado after the fashion of a marine
screw propeller, or like the sails of a windmill. The grain is elevated by
the screw running at a high speed within a closed iron casing; the grain is
fed in at one side of the case, and driven out at the other into a tube or
spout, directed to whatever place it may be convenient to drop it. The
screw may have a rim to it, and so make a wheel of it; it will answer fully
as well. If it is fixed on the first fan spindle it will act by its shovel-like
propensities and blast, if on the drumm spindle as an exhauster; it may be
put in any suitable place.
The second dressing machine.-I obtain wind for this by taking it out of
the first fan, and conducting it up a tube while the fan is rotating in the usual
way, or a small fan may be fixed on the shaker crank; if there is no
dressing machine, I blow the corn through valves or air pipes, taking the
light grain from the heavier, and finally dropping it into sacks.
Elevating the straw.- employ sets of revolving rakes working round a
drum in suitable bearings, the straw following in a concave grating; one or
more sets of these rakes may be used, they may be fixed on the same frame,
or a separate carriage may be employed, according to the length of the same.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Charles James Newbolt in the Great Seal Patent
Office on the Sth March 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
JAMES NEWBOLT, of Millbrook, near Southampton, Engineer, send greeting.
WHEREAS 1der most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of September, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-eighth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Charles James Newbolt, Her special licence that 1, the
said Charles James Newbolt, my executors, administrators, and assigns, or

page_text: such othersas I,the said Charles James Newbolt, 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 THE ARRANGEMENT AND CONSTRUC-
TION OF FIXED AND PORTABLE COMBINED THRASHING MACHINES," upon the condition
(amongst others) that I, the said Charles James Newbolt, 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 Charles James Newbolt, 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 and accompanying Drawings, that is to say :-
This Invention has for its object improvements in the arrangements of
thrashing machines. In the machines now in ordinary use the shakers
and the vibrating boards or riddling apparatus are driven by separate
cranks or excentrics, that is to say, one set of cranks on one axis aro
driving the shakers, the other set on another axis are driving the vibrating
boards or riddling apparatus, sometimes a double set are on one axis
Now, according to my Invention, I drive with one set of cranks only. The
set driving the shakers, for reference, I shall call the first crank, the other,
driving the riddling apparatus, the second crank.
Beneath the shakers, from some part thereof, or the driving block, or
from the first crank direct, I connect suitable rods running to the vibrating
boards on the top or upper side, where they are firmly bolted or fixed, a joint,
notch, or other suitable contrivance intervening to render them flexible to
take the play of the cranks in their revolutions; on these rods the shaker
ends may be carried, and so dispense with the radial links usually applied
to hold them in their position. Half the rods or shakers would run to one
board, half to the other, when there are two in the machine; the shakers may
be used without the rods if preferred; connect them in any manner, the
vibrating boards and the shakers will work together.
Having thus stated the nature of my Invention, I will proceed to describe
more fully the manner of performing the same.
Fig. 1, the Drawing hereunto annexed, represents a longitudinal section

page_text: of so much of a thrashing machine as will enable mne readily to describo the
improvements applied to my present Invention.
A is the cranked axis, from which the straw shakers and riddling apparatus
receive their notion; the shakers are connected to the crank from the centre
(but they may be connected from either end, or any desirable part); C, C,
are the connecting rods, which convey the motion from the crank to the
vibrating boards, carrying the shakers at alternate ends; the same time the
bracket. Bis supporting the shakers at that end, and is connected at the foot
to the rod C', the rod is bolted to the first vibrating board E, at the other
end to the crank block II; 1) is another bracket, connected to the second
vibrating board or under one; there are one on each side supporting a cross
or bridge piece E", upon this piece E" the rods or shakers are connected that
are to give motion to this board, it is kept sufficiently high above the first
board to allow the cavings to descend freely and wide enough to allow of its
working; G is a block interposing between the shakers and the rods C", to
compensate for height when required; at E in the rods is a joint or notch,
or piece of thin steel to render them flexible, so as to take the play of the
cranks in their revolutions. Fig. 2 is a plan of the same, shewing one mode
of the applications and connections. H, H, H, H, are the blocks, to which
the rods are connected to the cranks, at the other ends they are fastened
to the pieces marked E' and E"; I is a cross bar to steady the shakers
upon which the brackets B are fastened.
Having thus described the nature of my said Invention, and the manner
in which the same is to be performed, I wish it to be understood that
without limiting myself to these precise details, that that which I claim is the
manner of driving the vibrating boards and shakers with one crank, and
the supporting of the shakers on the rods or boards, either combined or
separate, as herein-before described and illustrated on Drawings, or any
mere modification thereof.
In witness whereof, I, the said Charles Jaines Newbolt, have hereunto
set my hand and seal, this Eighth day of March, in the year of
our Lord One thousand eight hundred and sixty-five.
CHARLES JAMES NEWBOLT. (L.S.)
