page_text: Improvements in Thrashing Machines.
I, CHARLES WILLIAM DORLIN, of The Eagle Iron Works, Bromley Road,
Colchester, in the County of Essex, Engineer, do hereby declare the nature of
this invention to be as follows:-
This invention relates to thrashing machines and it consists in the improve-
ments hereinafter more particularly specified, the object being to adapt the
machine for cobbing or drawing clover as well as for thrashing corn.
My improved machine consists essentially of a beater drum, of a set of shakers,
of a vibrating sieve or screen to receive the cobs and cavings from the drum and
shakers, of a second sieve or screen to receive the cobs separated from
the cavings by the first sieve or screen, of a third sieve or screen, for separating
the plantain or like seeds from the cobs, of a box to receive the cobs, of an
elevator for lifting the cobs from the box, of a seed barrel or drum, and of one or
more winnowing or dressing devices.
The action of the machine is as follows:-The clover is passed in between the
beater drum and the breast in the well-known manner. The cobs and cavings
from the drum and shakers pass on to the vibrating sieve or screen which separates
the cobs from the cavings; the cobs then pass on to the second sieve or screen
and while passing over it are winnowed, thus taking out any slivers light cobs or
leaf, leaving the best cobs and any clover seed or plantain that might be drawn
or shelled during the cobbing process, which latter pass over the plantain seed
sieve which separates the said seed and delivers it through a suitable shoot.
The cobs then pass to a box from which they are elevated into the seed barrel
or drum which rubs the seed out of the cobs. The seed and cobs then pass over
a suitable sieve and are winnowed the seed being separated from the cobs or
chaff, the latter being blown through a suitable shoot into bags. Should any
cobs remain out of which the seed has not been rubbed or any short slivers they
pass through a suitable shoot over a sieve or screen which sifts the cobs from the
slivers the former being returned to the elevator box to be elevated again to
drum or seed barrel. The seed passes from the last named sieve or screen. to the
winnowing devices which separate it into bests" and "tailings."
For thrashing corn the clover seed sieves or screens are removed and suitable
corn sieves substituted.

I, CHARLES WILLIAM DORLIN, of The Eagle Iron Works, Bromley Road,
Colchester, in the County of Essex, Engineer, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention relates to thrashing machines and it consists of the improve-
ments hereinafter more particularly specified, the object being to adapt the
machine for cobbing or drawing clover as well as for thrashing corn.

In the accompanying drawing which illustrates this invention;-
is a view in side elevation-partly in section.
Figure 2 Sheet No. 1 is a section view on line Figure 1, and
Figure 3 Sheet No. 2 is an end view partly in section.
Throughout the views similar parts are marked with like letters of reference.
The improved machine consists essentially of a beater drum A, of a breast A',
of a set of shakers B, of a vibrating sieve or screen C arranged to receive the
cobs and cavings from the drum A and shakers B, of a second vibrating sieve or
screen arranged to receive the cobs from the drum and also those separated
from the cavings by the first sieve or screen C, of a winnowing device consisting
of sieves or screens E and E¹ provided with a suitable blast, which takes out any
slivers, light cobs and leaf, leaving the best cobs and any clover seed or plantain
that may be drawn or shelled during the cobbing process, of a sieve or screen E²
for separating the plantain and like seeds, of a box F to receive the cobs, of a
box J to receive the plantain and like seeds, of an elevator G for lifting the cobs
from the box F, of a barrel or drum H which rubs the seed out of the cobs, of
a sieve or screen K for separating the cobs and sliver from the seed, of a winnowing
or dressing device consisting of sieves or screens L and L¹, of a fine sieve or
screen M for separating the tail seed, of a rotary blast fan N delivering air both
between the sieves or screens E, E and the screens L L' through suitably shaped
orifices e and l, of an exhaust fan ( for drawing out the small slivers, of a shoot P
for the chaff and slivers, of a shoot Q for the tail seed passing through the sieve
or screen M, of a shoot R for returning the cobs to the clevator box F which
shoot is preferably provided with a sieve or screen R¹ to remove any slivers that
may remain and of a shoot S for the delivery of the best seed passing through
the sieves or screens L and L¹.
Those parts to which reference has not been made are of the usual construction
in thrashing machines and present no novel features.
The action of the machine is as follows:-
The clover is fed in between the beater drum A and the breast A¹ in the well-
known manner. The cobs and cavings from the drum A and shakers B pass on
to the vibrating sieve or screen C which separates the cobs from the
cavings: the cobs then pass onl to the second vibrating sieve or
screen I). From thence they pass into the winnowing device E, E,
which separates the sliver or short lengths of straw, the light cobs, and
the leaf, from the best cobs and any clover seed or plaintain seed that
might be drawn or shelled during the cobbing process. These latter then
pass over the sieve or screen E2 which separates the plantain seed which falls into
the box J, and is delivered through a suitable shoot J. The clover seed and
cobs then pass to the box F from which they are elevated and delivered into the
seed barrel H by the elevator G. Here the seed is rubbed out of the cobs. Both
then pass over the sieve or screen K which separates the cobs and sliver from the
seed which then passes to the winnowing device L and L¹ which separates the

page_text: seed, which passes to a shoot through which it is delivered. The cobs and chaff
pass away through the shoot P and the tail seed and cobs that remain out of
which the seed has not been rubbed pass over the sieve or screen M which
separates the tail seed from the cobs, the latter together with those from the
sieve or screen K returning to the elevator box I by means of the shoot R to
be elevated again to the seed barrel and the latter escaping by the shoot Q.,
When the machine is used for threshing corn the sieves or screens used when
threshing clover-which are of finer mesh than those used when threshing corn,
are removed and other substituted, and the spout connecting the top of the
elevator with the screen K is opened to allow the corn raised by the elevator G
to pass direct on to the said screen without passing through the seed barrel H.
When the machine is used for threshing clover the spout is closed by a suitable
slide so as to cause the seed to pass through the seed barrel H.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
(1) The improved threshing machine herein described and illustrated by the
accompanying drawing for threshing clover as well as corn.
(2) In a threshing machine, the combination with the usual beater drum,
breast, shakers, sieves, elevators and dressing sieves, of a seed barrel such as H
and an exhaust fan such as O, as and for the purpose herein specified.
