Improvements in Apparatus for Paring, Cutting, and Grating
Vegetables and the like.
I, CARL WOLF, Sole Proprietor of the Firm of Carl Wolf, Soehne, Manu-
facturers of Zwickau in the Kingdom of Saxony, German Empire, do hereby
declare the nature of my invention and in what manner the same is performed
to be particularly described and ascertained in and by the following statement :-
The present invention consists of an apparatus for household purposes which may
be used for paring or slicing or otherwise cutting vegetables or for grating the same,
according to the necessity of the case, the said apparatus consisting mainly of a pair
of rotary cutters, mounted within a casing and adjustable with regard to a disc
arranged behind the same, said disc being for the purpose of determining the
thickness of the slices to be cut off. These knives are detachably connected with
the driving spindle and may be taken out and replaced by a grater disc when it is
required to grate. Outside the said casing is arranged a paring mechanism, as
hereinafter more particularly described. In operation the vegetable to be sliced or
pared is either inserted into an opening in the front of the casing with its end
against the cutters, which will on rotating cut off slices from the same corresponding
in thickness to the distance between the
and the cutters, or if the said
vegetable or fruit is to be pared the same is stuck onto a spike projecting bori-
zontally from the front of the said casing and rotated against a longitudinally
operated paring knife.
And in order to make the present invention more easily intelligible reference is
had to the accompanying drawing in which similar letters denote similar parts
throughout the several views:-
Fig. 1 is a side elevation of the apparatus with the casing removed and shown in
dotted lines, part of the sleeve of the driving spindle being in section,
Fig. 2 is a front elevation of the apparatus,
Fig. 3 a part detail elevation of the cutters and disc,
Fig. 4 a top view, front, back and side elevation of a device to be attached to the
inlet of the casing when the apparatus is to be employed for cutting beans,
Fig. 5 is a part front view and a side elevation of the grater disc and
Fig. 6 a detail view of the spike or prong for the reception of fruit to be
pared &
Fig. 7 a detail of the knife.
The spindle b is suitably mounted to rotate in the casing C of the apparatus,
being provided with a crank handle e for the purpose. The cutters ff are also
mounted to rotate with the spindle b said cutters being arranged in front of the
disc d, the position of which latter with regard to the cutters determines the
thickness of the slices to be cut. The position of this disc is fixed by the sleeve of
the crank handle e which is provided with an internal thread to engage a thread on
the spindle b and the position of said cutters with regard to that of the disc d is
varied by means of the device illustrated in detail in Fig. 7. The cutters ff are
attached to the sleeve g encircling the spindle b, said sleeve extending through the
sleeve g of the disc d. This sleeve or boss g¹ is reduced in diameter for a part of
its length g² and is provided with a longitudinal slot k in which a pink on the
sleeve is free to slide. On the reduced portion g² of the disc boss g¹ is fitted a
ring or sleeve i having a slot h slanting across the same after the manner of a screw

page_text: thread and engaging over the pin k of the cutter sleeve g. This ring i is revoluble
on the boss g¹ but is fixed in the longitudinal direction, so that on turning the
ring on the boss g' g of the disc d and retaining the latter stationary the
cutters ff may be shifted further away from or nearer to the said disc, since
the sleeve of the same will be actuated telescopically in the boss of the disc. Thus
if it is required to shift the position of the cutters ff relatively to that of the
disc d, it is only necessary to screw back the crank arm e the required distance then
to turn the ring i by means of its handle and tighten the crank again against the
end of the sleeve g.
The vegetable to be cut or sliced is inserted into the opening F of the casing and
on revolving the cutters will be cut in slices corresponding in thickness to the
distance of the disc d from the said cutters. The opening F may be closed by a
suitable cover o, pivoted at p. The sliced fruit falls out of the casing C at an
opening at the bottom of the same (Fig. 2). When it is required to slice beans
the cover o may be replaced by a slide q, shown in plan and front, rear and side
elevation in Fig. 4, this slide or guide piece is adapted to be arranged in suitable
grooves provided at the sides of the casing opening F, whilst the spike q³ at
the bottom of the said slide 9 fits into a suitable sheath in the casing. At the
front the said guide is provided with three or more hopper shaped inlets q³,
whilst the interior surface of the plate is provided with tapering slots q' through
which the beans pass and are cut up in slices by the cutters fl. The shape
of the slots will have the effect that when the beans are introduced into the
inlets the cutters in slicing the same will have a tendency to pull them
further through, so that by the time one cutter has cut off a slice the bean will
have been pulled far enough through the opening q' for the next cutter to take
the next slice off, and thus when once the bean has been fed into the inlet it
needs no further pushing, but will be automatically drawn into the casing C by
the cutters. The apparatus may also be used as a grater, by simply removing
the disc d and cutters f from the spindle and placing the grater disc m thereon
(Fig. 5) which is also secured in position by the crank arm e.
The apparatus is also provided with a paring mechanism consisting of the
following parts-The sleeve of the front plate of the casing C is provided
with an upwardly extending arm D in which is mounted to slide vertically a
rods, the lower end of which rests on an excentric part of the spindle b,
whilst the upper end is provided with a roll t adapted to impinge against the
bevelled end of a sliding tooth rack u. A stationary tooth rack v is fixed to
the upper end of the arm D and the sliding rack u is guided by pins in the
said arm D and y in the stationary rack v, engaging in slots of the sliding rack.
A flat spring w tends to keep the sliding rack in its forward position; guided
on the said racks u is a carriage z having two pawls and 22 said carriage
supporting on a pivot a downwardly extending arm A having a paring knife B
at its lower extremity, the said arm A being actuated inwards towards the spindle b
by means of a spring C¹. The pawls engage respectively in one of the
racks u and v and the spindle b is formed to or provided with a spike a at its
forward end over which the fruit or vegetable to be pared is placed. The
device operates in the following manner :-On rotating the spindle 6 the slide s
will be raised and lowered at each revolution thus at each revolution pushing
the sliding rack u back one tooth and with it the carriage z, on the forward
movement of the rack u the carriage will be retained in its position by the
stationary rack w and the pawl so that as the spindle bis rotated the
carriage will, be gradually backed along the spike a on which the fruit is
placed, the knife B will be kept against the said fruit by means of the spring C¹
and as the fruit is being revolved during this time, the same will be pared by
the said knife B.
The apparatus may be secured to the table in convenient manner by means
of the screw E' and the brackets E E.
