AN IMPROVED MACHINE FOR SORTING OR SEPARATING AND CLEANING GRAIN OR SEED
Year: 1880

page_text: LETTERS PATENT to Henry Harris Lake, of the Firm of Haseltine, Lake,
& Co., Patent Agents, Southampton Buildings, London, for an Invention
of "AN IMPROVED MACHINE FOR SORTING OR SEPARATING AND CLEANING
GRAIN OR SEED." A communication from abroad by William A. Stone, of
Prague, Austria.
PROVISIONAL SPECIFICATION left by the said Henry Harris Lake at
the Office of the Commissioners of Patents on the 6th December 1880.
HENRY HARRIS LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. AN IMPROVED MACHINE FOR SORTING OR
SEPARATING AND CLEANING GRAIN OR SEED." [A communication from abroad
by William A. Stone, of Prague, Austria.]
This Invention relates to an improved grain sorting or separating and dressing
or cleaning machine, which is applicable to all kinds of grain or seed, and which
separates the various sized grains in a much better manner than any sorting
cylinder hitherto known.
In carrying my said Invention into practice I provide a hopper, into which the
grain or seed is poured, and I regulate the fall of the latter by means of a rough
slowly revolving transporting roller. A blower or blowing apparatus is placed in
any convenient position, and has the effect of cleaning or dressing the grain or
seed which passes from the hopper over four or more flat sieves placed one below
the other; the grain is caused to pass over the whole surface of each succeeding
sieve by placing under the frame of each one a solid bottom. By these means I
separate the grain fed into the apparatus into six qualities, and the separation is
effected in a better manner than has been possible by any machine heretofore
made. For the sieves I use wire gauze of a suitable mesh or gauge for the work
to be effected.
I have hitherto used fourteen different sieves for a machine, each of which sieves
may be inserted into any one of four accurately balanced sieve-frames provided in
the machine, and these sieves are sufficient for the most exacting demands for
sorting or separating all kinds of grain or seed.
A machine constructed according to this Invention is easily operated by one
person, is simple in construction, so that any unskilled workman will readily learn
to use it, and is easily transported as its dimensions are small; it can therefore be
used in granaries which are not easily accessible, and its yield is unsurpassed both
as regards quantity and quality.

HENRY HARRIS LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. AN IMPROVED MACHINE FOR SORTING OR
SEPARATING AND CLEANING GRAIN OR SEED." A communication from abroad
by William A. Stone, of Prague, Austria.
This Invention relates to an improved grain sorting or separating and dressing
or cleaning machine, which is applicable for the treatment of all kinds of grain or
seed, and which will effect the separation of the various sized grains in a much
more effectual manner than machines for the same purpose as heretofore
constructed.
The said Invention is illustrated in the accompanying Drawing, in which
Figure 1 is a side elevation partly in section, and with a portion of the casing
broken away of my improved machine, and
Figure 2 is an end elevation partly in transverse section of the same.
In carrying the said Invention into practice I provide a hopper A, into which
the grain or seed is poured, its fall being regulated by means of a rough, slowly
revolving, transporting, or feed roller B. The grain or seed as it leaves this roller
is purified by means of a current of air produced by the blower C, and is conducted
over four or more flat sieves D, E, F, G, placed one below the other. To compel
the grain to pass successively over the entire surface of each of these sieves I place
under the frames of the said sieves solid bottoms H³, H², H³, H*, so that the grain
is separated into six different grades or qualities which leave the machine at the
spouts 1, 2, 3, 4, 5, 6, the separation being thus effected in a better manner than
has been practicable by any machine hitherto constructed.
In constructing the said sieves I employ wire gauze of a mesh suitable for the
work to be effected. It has been found by experiments that wire-gauze having
a mesh of from 3 to 30 of the ordinary gauge is advantageous.
Fourteen different sieves (each of which may be inserted in any one of the
four accurately balanced sieve frames) will be found sufficient for sorting. or
separating all kinds of grain and seed.
"A machine constructed according to this Invention may be easily operated by one
person; it is simple in construction, so that even an unskilled workman will readily
learn to use it, and, as its dimensions are small, it may be conveniently transported,
and is therefore available for granaries which are not easily accessible. Moreover
its operation affords results both as regards quantity and quality hitherto
unobtainable.
Having thus fully described the said Invention as communicated to me by
my foreign correspondent, and the manner of performing the same, I wish it
understood that I claim,-
The improved machine consisting of the parts constructed and combined
substantially as shewn in the Drawing and operating as and for the purposes
specified.
In witness whereof, I, the said Henry Harris Lake, have hereunto set my hand
and seal, this Sixth day of June, in the year of our Lord One thousand eight |
