Improvements in Machines for Washing and Peeling Potatoes
I, WILLIAM THOMPSON of King Street Burnley in the County of Lancaster,
Soap Manufacture do hereby declare the nature of this invention to be as
follows
This invention relates to machines for washing and peeling potatoes, and consists
of an arrangement whereby I am enabled to wash and peel potatoes, better and far
more expeditiously than in existing machines
The receptacle or receiver for the potatoes preferably consists of a stationary
cylinder of perforated sheet metal in a suitable trough Through the centre of
this cylinder, I pass a shaft, on which I slip a sleeve o tube, carrying metal
rectangulu fime, and on the said sleeve I arrange spirally around it, a number of
pegs or projections, which may consist of tubes sciewed into the said sleeve
said sleeve or tube, rectangular frame, and spirally arranged pegs, I cont on wrap
with perforated serrated or corrugated, or other giating metal or material
sleeve is fixed to the shaft by set screws
The
The
The shaft of the cylinder is mounted on two radial arms or levers, extending
from a shaft at one side of the machine The said adial arms or levers are for
raising and lowering the cylinder in and out of the trough, so that the potatoes
may be readily tal on out On the shaft from which extend the radial arms or
levers, is a toothed quadrant, which engages with a worm, on
a shaft at right
angles to the shaft which caries the radial arms The worm shaft is provided
with a handle which when the cylinder is required to be raised or lowered is
turned, when the worm, acting in the teeth of the quadrant, gradually turns the
quadrant shaft This motion transmitted to the radial arms raises or lowers the
cylinder as de ned
On the shaft of the cylinder is a toothed gear wheel, which when the machine
1 set in motion for peeling potatoes engages with the teeth of another gear wheel,
fixed to a stud journaled to the trough The latter gear wheel may be readily put
in oi out of gen with the other, by shiling the stud oi shaft in its journal
When
the ear wheel has been slided in or out of gear, I make use of a dog, which drops
on the stud, and keeps it in the required position On the stud or shaft is the
dying wheel, which when pat in motion tuins the pegged shaft of the cylinder
and rectangular fiame at a rapid pace
The cylinder may be made in sections of perforated metal, each section over-
lapping a wie rod extending from one end to the other of the cylinder Any
section may be thus readily removed for repans The cylinder is provided with
a lid, which when the cylinder is taised may be allowed to fall against one end of
the trough, in position for the ready removal of the potatoes
This machine will wash and peel potatoes fat more rapidly than existing
arrangements the roughened surfices of the pegs of the like coming very
effectively into play, and thoroughly removing the peeling in cases where the
potatoes are very irregular in shape, which is not possible in ordinary machines
The trough may be provided with a plug or tap for the discharge of the water
contained therein, after the potatoes have been peeled and washed

I, WILLIAM THOMPSON of King Street, Burnley, in the County of Lancaster,
Soap Manufacturer, do hereby declare the nature of this invention, and in what
mani er the same is to be performed to be particularly described and ascertained
in and by the following statement
--
The invention relates to machines for washing and peeling potatoes, and consists
of an arrangement, whereby I am enabled to wash and peel potatoes, better and
far more expeditiously than in existing machines
The receptiele o leceiver for the potatoes preferably consist of a stationary
cylinder of perforated sheet metal in a suitable trough Though the centre of
this cvlindei I pass a shaft, on which I slip a sleeve or tube, carrying a metal
rectangular frame, and on the said sleeve I mange spirally around it, a number of
pegs or projections, which may consist of tubes screwed to the said sleeve The
said sleeve or tube, rectanguli fiame, and spirally arranged pegs 1 coat or wrap
with perforated, set rated, or corrugated, or other grating metal or material
sleeve is fixed to the shaft by set screws
The
The shaft of the cylinder is mounted on two radial arms or levels, extending
from a shaft at one side of the machine The said radial arms or levers are for
raising and lowering the cylinder in and out of the trough, so that the potatoes
may be readily taken out On the shaft, from which extends the radial arms or
levers is a toothed quadiant, which engages with a worm on a shaft at right
ingles to the shaft which carries the radial arms The worm shaft is provided
with handle, which when the cylinder is required to be used or lowered, is
turned, when the worm, acting in the tecth of the quadrant, gradually turns the
quadrant shaft This motion transmitted to the radial aims raises or lowers the
cylinder as desned
1
On the shaft of the cylinder is a toothed gear wheel, which when the machine is
set in motion for peeling potatoes engages with the teeth of another gear wheel,
hxed to a stud journaled to the trough The latter gear wheel may be readily
put in or out of gear with the other, by sliding the stud or shaft in its journal
When the gear wheel has been slided in or out of gear, I make use of a dog, which
drops on the stud, and keeps it in the required position On the stud or shaft is
the driving wheel, which when put in motion turns the pegged shaft of the cylinder
or rectangular frame at a rapid pace
The cylinder may be made in sections of perforated metal, each section over-
lapping a wire rod, extending from one end to the other of the cylinder Any
section may be thus readily removed for repurs The cylinder is provided with
a lid, which when the cylinder is 1aised may be allowed to fall against one end of
trough, in position for the ready removal of the potatoes
This machine will wash and peel potatoes far more rapidly than exiting arrange-
ments, the roughened surfaces of the pegs or the like coming very effectively into
play, and thoroughly removing the peeling in cases where the potatoes are very
irregular in shape, which is not possible in ordinary machines
The tough may be provided with a plug or tap for the discharge of the water
contained therein, after the potatoes have been peeled and washed
In the accompanying drawings, Fig 1 is a side elevation, and Fig 2 a plan of
my improved machine for washing and peeling potatoes
A is the trough within which is mounted cylinder B of perforated sheet metal
Cylinder B is mounted on shaft C, carried by two indil rms or lever, D, which
are secured to shaft and are for 1aising and lowering the cylinder in and out of
the tough for the ready removal of the potatoes in the manner heinafter
described.

page_text: On shaft I slip a sleeve or tube, around which I arrange spally or otherwise
a number of pegs or projections F, which may consist of tubes screwed to the said
sleeve The sleeve or tube, and pegs or projections F, I coat with perforated
metal or other grating or roughened surface The sleeve is fixed to the shaft C
by set screws
To put the machine in motion, short sliding shaft G having hand-wheel H at one
end, and gear wheel J at the other, is slided forward so as to engage with gear
wheel K on pegged shaft C, which is thus turned at a rapid pace, quickly washing
and pceling the potatoes, introduced into the cylinder through lid L When
the machine is in operation the trough is filled with water to the required extent
The cylinder B is provided with hasp M, which fits staple N on lid L, whereby
the lid is secured during the operation of washing and peeling Cylinder B is held
stationary by hooks or clasps O, which embrace shaft E
I will now proceed to describe my improved arrangement for raising and
lowering cylinder A, when the potatoes have been thoroughly washed and peeled
Short shaft G is slided back to withdraw gear wheel J from gear wheel K, which
will admit of the cylinder being raised
Shaft E is turned so as to raise radial arms D, and consequently the cylinder by
toothed quadrant P, which engages with worm Q When transverse shaft R is
turned by handle V, worm Q acting in the teeth of quadrant P gradually turns
shaft E, and by that means raises the cvlinder B through the medium of radial
arms D
A plug or tap X is provided to clear the trough of muddy water when desired
Figs 3 and 4 are side and front elevation respectively of a modification of my
invention a is a stationary cylinder oi receptacle for water and potatoes, in the
centie of which revolves shaft or axle which carries pegs or beaters c rotated
rapidly by handle d Pegs c, shaft b and casing a are coated with perforated
sheet metal or other corrugated or giating surface The receptacle is made water-
tight, and is provided with hand eyes e, by which the machine may be shifted
about A drip trough fis provided to retain any water, which may ooze through
the bearing of shaft Receptacle a and drip trough fare cleared of water by
screw plugs g and h
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
-
1 The improved construction of a machine for washing and peeling potatoes,
substantially as described and illustrated in Figs 1 and 2
2 The improved means for raising and lowering cylinder B in and out of
position for getting ready access to the potatoes, substantially as described and
illustrated in Figs 1 and
3 The modification represented in Figs 3 and 4, substantially as and for the
purpose described and set forth
