1, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
Member of the Institution of Mechanical Engineers, do hereby declare the nature
of this invention to be as follows:-
The chief features of this machine are a frame, a screw spindle or worn on to
which is fitted a carrier, a crank or handle, an adjusting frame, a cutting disc with
cutters or knives, and a grater with a knife, and the object of the invention is to
enable fruit and vegetables such as apples, potatoes, beans and the like, to be peeled,
cut and reduced to pulp. The fruit or vegetable to be operated upon is clamped
between suitable points, prongs or equivalent and the crank-handle is turned until
the fruit reaches the knife rotating in the opposite direction. Against this knife
the fruit is pressed and peeled as it proceeds. The peeled fruit is then placed in a
cylinder and pressed against the cutter-disc so that it is cut into pieces or slices by
the knives. If the grater-disc is inserted the fruit by being similarly pressed
against it is rubbed or triturated into a pulp.
If beans are to be cut they may be introduced through a special feeding orifice
or shoot.

COMPLETE SPECIFICATION.
Improvements in Machines for Peeling, Cutting, and Triturating or
Mashing Fruit, Vegetables, and the like.
A communication from ANTON TÄTZNER, of Leipzig, in the Empire of Germany.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
Chartered Patent Agent do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
This invention mainly consists in a combination of knives with a grater both
being connected to a common driving mechanism and mounted in one frame, the
object to be accomplished thereby being to peel, cut, triturate, or mash fruit or
other articles or material in one machine and under the action of one and the same
driving mechanism.
In the accompanying drawings:
-;
Figure 1 is a side view of the whole arrangement.
Figure 2 is a detail view of the carrier S.
Figure 3 is a view of the peeling mechanism.
Figure 4 a plan of the complete arrangement.
Figure 5 a plan and cross-section of the circular cutter D fitted with knives d.
Figure 6 is a plan and cross section of the grater B, and
Figure 7 a detail view of the device for throwing the peeling mechanism in or
out of gear as required.
As shown in the drawings the machine mainly consists of a frame G (Fig. 1) in
which a shaft or spindle W is supported by suitable bearings (Figs. 1 and 4) and
provided with a screw-thread along which travels the carrier S (Figs. 1, 2 and 4)

page_text: P
which in its turn is connected with an adjustable frame R (Fig. 4). In the centre
of the circular surface of the frame G is arranged a vertical spindle g (Fig. 4)
operated by means of bevel gearing from the main spindle W, on the end of which
is attached a crank-handle "K. When required, either the rotary disc D with
the cutters or knives d, or the grater B may be screwed on the lower end of
the spindle the screw thread being of such direction that when the machine is
operated the disc D or grater B will have a tendency to tighten on the spindle pr;
or D and B may be secured on the spindle p in any other convenient manner.
Upon the frame is also arranged over a suitable orifice, a receptacle C which serves
for the reception of the fruit to be peeled or triturated. The fruit or the like is for
this purpose placed in the said receptacle covered with the weight of wood or
metal, and by means of the handle K the conveyor-spindle W, conical gearing,
spindle and operating disc D or B, the machine is set in motion so that if p
carries the cutting disc with the knives d the fruit or the like is cut or sliced and if
it carry the grater-disc B the fruit is grated or triturated. Such leguminous
produce as beans or the like are introduced through the orifices for cutting or
triturating.

The peeling of fruit or the like is effected in the following manner;-The
frame R combined with the carrier D and the two points or centres a and b of which
serve for holding the fruit, may be horizontally shifted in the bearings n, either by
turning the crank-handle or simply by hand, according as the pin s of the carrier S
engages with the carrier spindle W or not. The cutter D or the grater B, or both,
are provided at their periphery with teeth D' B' respectively with which is arranged
to gear a toothed wheel or ring having no nave and arranged at right angles to
the cutter D or grater B. The toothed wheel is guided within a ring
(Figures 1, 3 and 4) pivoted by an arm to one of the bearings on the frame G.
The ring is provided with a pin with which engages the curved slot of a cam V
pivotted to an upright Figure 3. The cam V serves to lower or raise the ring r
and toothed wheel for the purpose of throwing the latter into or out of engage-
ment with the teeth B' or D₁ on the grater B or cutter D. The toothed wheel
carries the peeling device M on its periphery such device consisting of a lever r
and peeling knife; on turning the handle K after the toothed wheel has been
put into gear with the teeth of say the cutter D, the peeling knife ¹ is rotated
in a direction opposite to that of the handle K. The fruit to be pecled is, as before
stated, held by the two points or centres a and b of the frame and remains at rest in
this position within the ring while the peeling knive moves around it and performs
the peeling. One of the points or centres 6 is preferably made adjustable so as to
suit various sizes of fruit.
Having now particularly described and ascertained the nature of the said
invention as communicated to me by my foreign correspondent, and in what manner
the same is to be performed, I declare that what I claim is :-
A combined fruit peeling cutting and triturating machine characterized by the
frame G carrying a peeling-device M and a cutter disc. D with knives or cutters d
or when required instead of the cutter-disc a grater-disc B for the purpose of
enabling all the operations to be performed by the same mechanism substantially
as described and illustrated in the accompanying drawings.
