IMPROVEMENTS IN COMBINED THRASHING MACHINES
Year: 1862

page_text: LETTERS PATENT to Thomas Watts, of Carisbrooke, in the Isle of Wight,
for the Invention of "IMPROVEMENTS IN COMBINED THRASHING MACHINES,"
PROVISIONAL SPECIFICATION left by the said Thomas Watts at the
Office of the Commissioners of Patents, with his Petition, on the
'19th September 1862.
I, THOMAS WATTS, of Carisbrooke, of the Isle of Wight, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN COMBINED THRASHING
MACHINES," to be as follows:-
This Invention consists of forming a screw the thread of which is made
of thin iron plate. This screw revolves in the inside of a sheet-iron cylinder,
and is for the purpose of elevating and dressing corn and other grain.
The annexed sketch shews a view of the machine with elevator and
appendages attached. a shews the shute which conducts the corn to lower
hopper, which is fitted with a perforated bottom, thereby forming an extra
riddle, which carries short straws or ears over the hopper and drops them
on the outside; b, the lower hopper, which is fitted with a slide and opening
in order to let all grain out of cylinder when finishing; c, the cylinder
through which the grain is elevated and dressed; d, the pulley on screw
spindle which gives motion to screw inside of cylinder, receiving its motion
by means of a rectangular band or strop; E, the delivery box, to which
0.77

page_text: bags or sacks are hooked to receive the corn or other grain. Over the
shute a is a covering partially raised to shew the shute better. The advan-
tages derived from this Invention are simplicity, compactness, easyness of
action, reducing speed, and the number of oiling parts of ordinary machines,
thereby lessening wear and tear. This machine can be worked with two
straps only, and can be used with a small three horse-power engine.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Thomas Watts in the Great Seal Patent Office on
the 18th March 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
WATTS, of Carisbrooke, in the Isle of Wight, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of September, in the year of our
Lord One thousand eight hundred and sixty-two, in the twenty-sixth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Thomas Watts, Her special licence, that I, the said
Thomas Watts, my executors, administrators, and assigns, or such others
as I, the said Thomas Watts, 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 COMBINED THRASHING MACHINES," upon the condition
(amongst others) that the said Thomas Watts, my executors or adminis-
trators, 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 Thomas Watts, 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, reference being had to the accompanying Drawings,
and to the letters and figures marked thereon, that is to say:-
This Invention consists of forming a screw the thread of which is made of
No. 16 sheet iron, and is rivetted through oblong irons or beaters together, as

page_text: the dimensions of riddle or screen; 6, a thin sheet iron scoop which receives
the grain and throws it into screw opening, shewn by dotted lines as before
mentioned; f, the pulley on screw spindle which gives motion to screw
inside of cylinder, receiving its motion by means of a rectangular band or
strap g from lower pulley. .
Fig. 2 shews the construction of screw half size. The oblong marks on
spindle are end views of irons or knives which are rivetted to spindle, and
which are of themselves beaters for hawning the barley and cleaning all other
grain. I do not confine myself to the number shewn, as I may desire to
increase the number, if found necessary, in a transverse direction, namely,
riveting them into the plates of screw, so that barley of any season may be
properly cleaned and hawned; h, h, h, h, are knives or cutters rivetted in
screw plates. Fig. 3 shews side view of cutter; Fig. 4, section of cutter.
The screw shewn on Fig. 1 is the size, according to scale, for a 3-horse
machine, but it is obvious I can make them any size.
The advantages to be derived from this Invention are, efficacy, simplicity.
compactness, and freedom of action; no ordinary barley aveller is required,
being one of itself. It scours the corn in its passage up the cylinder and
polishes it, and rubs the smut off wheat to a very great extent.
This Invention can be advantageously worked with a three-horse engine;
no instructions are required to the men; its only to oil the bearings, put on
strap, and there it will stay.
Having thus described the nature and object of my Invention, and the
manner in which the same should be carried into effect, I declare that
what I claim as the Invention intended to be secured by the herein-before
in part recited Letters Patent is, the general arrangement and combination
of parts,substantially as herein-before detailed and described and illlustrated
on Drawings, or any mere modification thereof.
In witness whereof, I, the said Thomas Watts, have hereunto set my
hand and seal, this Eighteenth day of March, in the year of our
Lord One thousand eight hundred and sixty-three.
THOMAS WATTS. (L.S.)
