1, FRIEDRICH SCHULTE, of Kalk near Cologne, German Empire, Engineer, do
hereby declare the nature of this invention to be as follows:-
According to my present invention I subject potatoes contained in a receptacle to
the action of a series of revolving rasps which, while they rasp off the skin from the
potatoes immediately in contact therewith, at the same time impart motion to the
potatoes so as to bring them all successively under the action of the rasps. For this
purpose a cylindrical casing is closed at bottom by a disc mounted on a vertical axis
to which rotary motion is imparted by bevil gear from a horizontal shaft passing to
the outside and rotated by a crank handle. The disc consists of a number of radial
bars connected to a central boss and to a ring at the periphery, to which bars are
fixed a number of rasps, by preference curved so as to lie in concentric circles, and
rising at a slight angle from the bars, which, together with the rasps thus form a kind
of grid upon which rest the potatoes charged into the casing. The part of the casing
in which the potatoes are situated is covered with a brush surface that projects inwards
to a certain extent at different points of the circumference, thus offering obstructions
whereby the potatoes are prevented from being carried round with the disc as this
rotates, and thus the lower layer is subjected to the action of the rasps, which both
remove the skin and move the potatoes about, so that by degrees all the potatoes are
brought under their action. The top of the casing is closed by a cylindrical vessel
filled with water, hinged to the casing so as to form a lid, and this vessel has a rose
attached to its under side, through which a spray of water passes down among the
potatoes as these are subjected to the action of the rasps, whereby the skins, as they
are removed, are washed down into a shoot below the disc, which delivers them into
a receptacle. The casing has an opening in its side closed by a slide and provided
with a shoot, so that when the slide is opened, after the potatoes have all been skinned,
they are thrown by centrifugal force through the shoot into a receptacle outside.

page_text: I, FRIEDRICH SCHULTE, of Kalk near Cologne, German Empire, 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
According to my invention 1 subject potatoes contained in a receptacle to the action
of a series of revolving rasps which, while they rasp off the skin from the potatoes
immediately in contact therewith, at the same time impart motion to the potatoes so
as to bring them all successively under the action of the rasps. For this purpose a
cylindrical casing A shewn at Fig. 1 of the accompanying drawing, is closed at
bottom by a disc a mounted on a vertical axis d to which rotary motion is imparted
by bevil gear from a horizontal shaft e passing to the outside and rotated by a crank
handle The disc consists of a number of radial bars connected to a central boss
and to a ring at the periphery, to which bars are fixed a number of rasps b, by
preference curved so as to lie in concentric circles as shewn, and rising at a slight
angle from the bars, which, together with the rasps thus form a kind of grid upon
which rest the potatoes charged into the casing.
G
Fig. 3 shews a detached view of one of the bars with its rasps and Fig. 4 shews
a section of the same.
The part of the casing A in which the potatoes are situated is covered with a brush
surface g that assists in the removal of the skin from the potatoes and that projects
inwards to a certain extent at different points of the circumference, thus offering
obstructions whereby the potatoes are prevented from being carried round with the
disc as this rotates, and thus the lower layer is subjected to the action of the rasps,
which both remove the skin, and move the potatoes about, so that by degrees all the
potatoes are brought under their action. The top of the casing A is closed by a
cylindrical vessel B filled with water, hinged to the casing so as to form a lid, and
this vessel has a rose i attached to its underside, through which a spray of water
passes down among the potatoes as these are subjected to the action of the rasps,
whereby the skins as they are removed, are washed down into a shoot C below the
dise, which delivers thein into a receptacle D. The casing has an opening in its
side closed by a slide k and provided with a shoot so that when the slide is opened,
after the potatoes have all been skinned, they are thrown by centrifugal force through
the shoot into a receptacle E outside.
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:
Apparatus for skinning potatoes consisting of a casing A with rotating bottom a
provided with rasps, and with a fixed brush surface g, the casing being closed at top by
a vessel B containing water, and having below it a shoot for discharging the skins
and at its side a door and shoot for discharging the skinned potatoes, substantially
as herein described.
