Improvements in Machinery for "Snelling Peas and Beans.
I, ALFRED JULIUS BOULT of 323 High Holborn, in the county of Middlesex, M.I.M.E.,
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:
The object of the invention is to design a machine in which peas and beans may be
thrashed and effectually separated from the straw and pods without in any way
injuring the peas or beans; and it consists essentially of a perforated cylinder made
of leather or other soft material supported by and caused to revolve upon a shaft
having fixed to it a series of beaters covered with leather or other soft material and
caused to revolve in the same direction as the cylinder, but at a much greater speed.
The straw with the peas or beans are inserted at one end of the revolving cylinder
and pass through to the other end where the straw is discharged; the beans or peas
being thrashed out during the passage of the straw through the cylinder; the beans
or peas being separated by passing through the perforations in the cylinder below
which a travelling apron is placed for the purposo of catching the peas or beans and
separating them from any refuse which may find its way with them through the
perforations specified.
Figure 1 is a perspective view partially in section of this improved machine.
Fig. 2 is a cross section of the same.
In the drawing A represents a cylinder perforated with holes of sufficient size to
permit the free passage of the vegetable to be thrashed. This cylinder should be made
of leather, rubber, or other soft material and is supported upon the shaft B by arms C
which are secured as indicated to the bearings D which are journalled upon the
shaft A as shown.
At suitable points in the shaft A is secured a series of beaters E shaped
substantially as shown and set at such an angle that in revolving they assist the straw
to travel towards the discharge end of the cylinder. These beaters are also to
be covered with leather rubber or other soft material. The cylinder is carried as
indicated in a suitable frame. The straw is fed in through the opening G at one end
of the cylinder and discharged from the other end where a perforated apron H is
placed for the purpose of sifting any peas or beans which may be carried out of the
cylinder with the straw. An endless apron I placed below the cylinder A and is

page_text: set at an angle as indicated. The top surface of this apron is caused to travel in an
upward direction, as indicated by arrow, so that any straw or dirt falling through the
perforations in the cylinder A will be carried up and discharged over the high end of
the apron I while the peas or beans will roll towards and be discharged over the low
end of the apron thereby completely separating the peas or beans from all refuse.
In practice it has been found that the cylinder A should be made to travel about.
twenty revolutions while the beaters E which revolve in the same direction should be
made to travel at about one hundred and eighty revolutions. The frame F should be
covered with canvas.
It should have been mentioned that when the pea or bean pods are fed into the
machine they fall to the bottom of the cylinder between the longitudinal ribs J. As
the cylinder revolves they are brought to the top whence they fall by gravitation past
the beaters E which strike the pods and effectually shell the peas or beans. It is not
necessary that the straw should be fed in with the beans and in this machine green
peas can be as effectually shelled as ripe peas.
Having now particularly described and ascertained the nature of the said invention,
as communicated to me by my foreign correspondent, and in what manner the same
is to be performed, I declare that what I claim is:—
1. A machine for thrashing beans and peas composed of a perforated cylinder caused
to revolve upon a shaft having a series of beaters attached to it within the cylinder,
the said beaters revolving in the same direction as, but at a greater speed than, the
cylinder, substantially as and for the purpose specified.
2. A machine for thrashing beans and peas composed of a perforated cylinder having
a series of longitudinal ribs on its inner surface and caused to revolve upon a shaft
having a series of beaters attached to it within the cylinder, the said beaters revolving
in the same direction as, but at a greater speed than, the cylinder, substantially as and
for the purpose specified.
3. A revolving perforated cylinder A having a series of longitudinal ribs J formed
on its inside in combination with a series of beaters carried on a shaft passing through
the cylinder, and caused to revolve in the same direction as, but at a greater speed
than, the cylinder, substantially as and for the purpose specified.
4. A machine for thrashing beans and peas composed of a perforated cylinder A
made of leather rubber or other soft material and caused to revolve upon a shaft having
a series of beaters covered with leather rubber or other soft material attached to it
within a cylinder, the said beaters revolving in the same direction as, but at a greater
speed than, the cylinder, substantially as and for the purpose specified.

5. A machine for thrashing beans and peas composed of a perforated cylinder A made
of leather rubber or other soft material, and caused to revolve upon a shaft having
series of beaters covered with leather rubber or other soft material attached to it within
a cylinder, the said beaters revolving in the same direction as, but at a greater speed
than, the cylinder, in combination with the perforated apron H, substantially as and
for the purpose specified.
6. A machine for thrashing beans and peas composed of a perforated cylinder A
made of leather rubber or other soft material, and caused to revolve upon a shaft
having a series of beaters covered with leather rubber or other soft material attached
to it within a cylinder, the said beaters revolving in the same direction as, but at a
greater speed than, the cylinder, in combination with a slanting endless apron caused
to travel so that its top surface shall move in an upward direction, substantially as and
for the purpose specified.
