PROVISIONAL SPECIFICATION.
A New or Improved Potato Dressing Machine.
I. THOMAS MOLISON, of Balweain, Kirkcaldy, in the County of Fife, North
Britain, Farmer, do hereby declare the nature of this invention to be as follows:-
This invention which relates to a new or improved potato dressing machine
consists of as follows-
In accordance with my said invention provide two standards or frames
which have suitable provision formed on, or attached to them so as to carry a
revolving cylindrical wire drum or riddle, which is preferably slightly elevated
at its one end, and driven by hand at its other end through the medium of an
ordinary cranked handle; at the end which is elevated mount a hopper for
feeding the potatoes into the said drum or riddle, after passing through which
the large potatoes are delivered on the top of a platform or table mounted at
the other end of the drum or riddle. In order to separate the earth &c. from the
small potatoes which fall through the meshes of the drum or riddle, I mount a
screen or finer riddle immediately underneath the said drum or riddle.
The action of the whole being such, that on the undressed potatoes (that is,.
large ones, small ones and earth &c.) being placed in the hopper the large
potatoes are caused to pass through the drum or riddle to the platform at its
other end, and the small potatoes and earth passes through the meshes of the
said drum or riddle on to the screen underneath through which the earth &c.
again passes, leaving the small potatoes, thus delivering the large potatoes
dressed on the platform, the small potatoes dressed on the screen, and the
earth &c. on the floor or ground.

COMPLETE SPECIFICATION.
A New or Improved Potato Dressing Machine.
1, THOMAS MOLISON, of Balweain, Kirkcaldy, in the County of Fife, North
Britain, Farmer, 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 which relates to a new or improved potato dressing machine
has for its object to dress, that is to say, to size and separate from the earth,
the potatoes in a much more efficient manner than hitherto.
And in order that my said invention may be more readily understood, and easily
carried into effect, I will proceed to describe the same with reference to the accom-
panying drawings, Figure 1 of which a side elevation of my improved machine.
Referring to the said drawings 1 construct of wood or other material, two
standards or frames A, which are suitably secured to each other, and provided or
formed with brackets a, so as to carry a hollow cylindrical wire drum or riddle B,
preferably so mounted as to revolve in a slightly inclined plane as shown, and
driven by means of an ordinary cranked hand "lever C, at its lower end 1, the other
end &, being provided with a suitable feeding hopper D, into which the undressed
potatoes are fed, and so allowed to pass through the said drum or riddle B, during
which the earth and small potatoes fall through the meshes of said drum or
riddle B, on to the inclined screen or finer riddle E, where they are retained or
.

page_text: separated from the earth which falls through on to the floor or ground, meanwhile
the large potatoes after having passed through said drum are delivered on a
platform or table F mounted at the delivering end of said machine; the said
screen E, and riddle B, may also if desired be constructed of different sized mesues
as shown, and the lower screen provided with an inclined central partition e, so as
to size the potatoes into three kinds namely, feeding delivered through opening e
seed through opening e², and large potatoes on platform F. The whole machine
may also if desired be made portable by means of suitably mounted front
wheels (r.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
―
In potato dressing machines, the general arrangement and combination of the
various parts constituting my revolving riddle machine, all substantially as, and for
the purposes hereinbefore described.
