I, WILLIAM SPEIRS SIMPSON, of 49 Battersea Park Road, Surrey, Engineer, do
hereby declare the nature of this invention to be as follows:-
--
The object of this invention is to peel or rasp the outer skin from potatoes by an
apparatus in two parts, each having a rotatory motion in the same or in contrary
directions, or by an apparatus in which one of the parts move or rotate, the other
part being stationary.
The apparatus may be of cone or equivalent shape, or one part may be parallel
with the other for the whole or a part only of the circumference.
The potatoes are inserted into the apparatus wholly or partially immersed in ȧ
tub or vessel of water.
The coned or other shaped parts of the apparatus may be composed of roughed
or jagged wire-punched metal, square or other angled edge wire or strips interlaced
by weaving or otherwise, or the walls of the cones or other shaped parts of the
apparatus may be composed of rings with sharp edges and one set of rings may be
caused to travel within or between the other set of rings or they may be parts
of rings.
1 prefer to use two cones, each mounted upon a horizontal shaft or shafts for
rotation in contrary direction by gearing, the cone mouths face each other with a
space between and with the edges paralleled or at an angle to each other, so that the
potatoes, under operation, always fall towards the lower portion and as the coues
rotate, the potatoes are continually being turned over by frictional contact, their own
resistance to rotation being sufficient to effect the rasping, skinning, or peeling
action.

Improved Apparatus for Removing the Skin from Potatoes.
I, WILLIAM SPEIRS SIMPSON, of 49 Battersea Park Road, Surrey, 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:
The object of this invention is to peel or rasp the outer skin from potatoes by an
apparatus in two parts, each having a rotating motion in the same or in contrary
directions, or by an apparatus in which one of the parts move or rotate, the other part
being stationary.
The apparatus may be of cone or equivalent shape or one part may be parallel
with the other for the whole or a part only of the circumference.
The potatoes are inserted into the apparatus wholly or partially immersed in a tub
or vessel of water.
The coned or other shaped parts of the apparatus may be composed of roughed or
jagged wire, punched metal, square or other angled edge wire or of strips interlaced
by weaving or otherwise, or the walls of the cones or other shaped parts of the
apparatus may be composed of rings with sharp edges and one set of rings may be
caused to travel within or between the other set of rings, or they may be parts
of rings.
The apparatus I prefer to use is constructed as shown in the annexed drawings
Figures 1 and 2 and having two cones A, B, carried by a horizontal shaft in a
box D, one cone B being fixed and the other rotated by gearing E, F, G, in a
contrary direction. The cone mouths face each other with a space between and
with the edges parallel or at an angle to each other, so that the potatoes under
operation always roll over & present fresh portions to the inner roughened surfaces
of the cones, the cones being turned by the handle H.
One of the cones, say B, has a door 1 for the insertion and removal of the
potatoes.
The box D may contain water to assist the rasping, skinning, or peeling action.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
In an apparatus for removing the
inner roughened surface cones A, B,
