IMPROVEMENTS IN MACHINERY OR APPARATUS FOR SEPARATING GRAIN FROM STRAWS, BROKEN OFF EARS, HUSKS, AND REFUSE, AFTER BEING THRASHED
Year: 1854

page_text: LETTERS PATENT to William Worby, of Ipswich, in the County of Suffolk,
for the Invention of "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR
SEPARATING GRAIN FROM STRAWS, BROKEN OFF EARS, HUSKS, AND
REFUSE, AFTER BEING THRASHED."
Sealed the 6th June 1854, and dated the 8th April 1854.
PROVISIONAL SPECIFICATION left by the said William Worby at
the Office of the Commissioners of Patents, with his Petition, on the
8th April 1854.
J, WILLIAM WORBY, of Ipswich, in the County of Suffolk, do hereby declare
the nature of the Invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS
FOR SEPARATING GRAIN FROM STRAWS, BROKEN OFF EARS, HUSKS, AND OTHER REFUSE,
AFTER BEING THRASHED," to be as follows:-
This Invention has for its object improvements in arranging a sieve or wire
work trough or cylinder, with a rotating axis and stirrer, or rake, in a suitable
frame. The axis has fixed on it numerous projections, arranged spirally
around it in such manner that, in addition to raking or stirring the grain
and matters within the trough or sieve, they move them in the trough, and
eject. or throw out such of the grain and matters which do not pass through

page_text: the sieve. The fixed projections on the axis are in part conical, and some of
them have more or less flat surfaces towards the end of the sieve or trough
where the matters not passing through are thrown out.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Worby in the Great Seal Patent Office on the
7th October 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
WORBY, of Ipswich, in the County of Suffolk, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of April, in the year of our Lord
One thousand eight hundred and fifty-four, in the seventeenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said William Worby, Her special licence that I, the said William
Worby, my executors, administrators, and assigns, or such others as I,
the said William Worby, 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 "IM-
PROVEMENTS IN MACHINERY OR APPARATUS FOR SEPARATING GRAIN FROM STRAWS,
BROKEN OFF EARS, HUSKS, AND OTHER REFUSE, AFTER BEING THRASHED," upon the
condition (amongst others) that I, the said William Worby, by an instrument
in writing under my hand and seal, 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 William Worby, 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) :-
This Invention has for its object improvements in arranging a sieve or wire
work trough or cylinder, with a rotating axis and stirrer, or rake, in a suitable
frame. The axis has fixed on it numerous projections, arranged spirally
around it in such manner that, in addition to raking or stirring the grain and

page_text: have more or less flat surfaces towards the end of the sieve or trough where
the matters not passing through are thrown out.
Having thus stated the nature of my Invention, I will proceed to describe
the manner of performing the same.
DESCRIPTION OF THE DRAWING.
Figure 1 shows a side elevation of the apparatus combined and constructed
according to my Invention; Figure 2 is a transverse section; and Figure 3,
an end view. In each of these Figures the same letters indicate similar
parts. a, is the axis of the stirrer, which I prefer to be somewhat conical,
the larger end being where the matters are fed into the trough or sieve
c, which I make of perforated metal or wire cloth, or other suitable
material, the holes being of a size suitable for the passage of the grain or
seed which is to be treated therein through them, whilst the pieces of straw
and refuse matters pass onward, and are thrown out at the end of the
trough or sieve c. The axis a has numerous projections thereon, set in a
spiral line around the axis, by which in the rotation of the axis the projec-
tions, as well as stirring the matters under process, also move them towards
the end, and there they throw out the refuse through the open end, which is
made of the form shewn at Figure 3, the other end being closed up. d is
the neck or smaller axes at the ends of the enlarged or conical axis a; e, e,
are the bearings in which the necks or smaller axes turn; f is the end
plate, only partly closing that end of the trough or sieve; g is the covering
of the trough or sieve; h is the hopper through which the matters to be
treated are fed into the trough or sieve; i is the spout where the refuse
matters are thrown out; j is the driving drum; k are curved bars to support
the sieve or trough; 1, 1, are the longitudinal framings. The projections b
are preferred to be of two kinds, conical and flattened, as are shown separately
at Figure 4, and these are used alternately, excepting near the end where the
refuse is thrown off, where it is considered desirable, to the extent of about one
turn, to have the projections all flattened.
I would state that this apparatus may be combined with and fed direct
from a thrashing machine, or it may be used as a separate machine.
Having thus described the nature of my Invention, and the manner of
performing the same, I would have it understood that I make no claim to any

page_text: of the parts separately, nor do I confine myself to the details; but what I
claim is, the combination herein described.
In witness whereof, I, the said William Worby, have hereunto set my
hand and seal, this Fifth day of October, in the year of our Lord One
thousand eight hundred and fifty-four.
Witness,
GEO. PITT,
