COMPLETE SPECIFICATION.
Improvements in Fruit Pulping and Juice Extracting Apparatus.
I, CHARLES HUNT, of Prince of Wales' Hotel, Belfast, County of Antrim, Ireland,
Doctor of Opthalmology, 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 has reference to improvements for the purpose of perfecting and
rendering more useful certain apparatus for extracting the juice of lemons, oranges
and similar fruit, as described in specification filed in pursuance of Letters
Patent dated 30th day of October 1897, numbered 25,163.
The invention described in said specification consists of a semi-globular
receptacle or cup having a recessed rim to fit into the grooved edges of a flanged
ring carrying an upwardly projecting conical dome or cupola provided with
vertical ribs or corrugations on its side and perforations round its base.
The receptacle or cup is furnished with a shank, and is attached removably by
a key or pin to a vertical shaft set in a foot step and working in suitable journals,
the whole superstructure being caused to vibrate or swivel rapidly in a horizontal
plane, by suitable bevel gear carried in a suitable casting or standard, and operated
manually by a lever handle.
The action of the apparatus is as follows:-
The lemon or orange is divided, preferably transversely to its longitudinal axis,
into two parts, and one half is placed with its cut surface upon, and pressed
gradually down over the dome or cupola by the pressure of the operator's hand,
while he rapidly turns the lever handle with his free hand, thus
causing the receptacle or cup to vibrate or swivel rapidly through the segment
of the bevel wheels until the pulp is ejected from the skin.
The extracted juice falling into the cavity round the base of the dome or cupola
percolates through the perforations into the semi-globular receptacle or cup, from
which it is removed by first taking off the dome, or cupola and then lifting the
receptacle or cup from the vertical shaft on which it is seated.
The defects in the apparatus thus described, are that (1) in order to remove the
extracted juice it is necessary to lift the receptacle or cup from its seat, (2) the.
gear described for imparting the necessary swivelling motion to the superstruc-
ture is complicated, and liable to become deranged, and (3) the apparatus generally,
is rather elaborate in appearance, and expensive to construct.
Now my present invention is designed to obviate these defects and
I will describe same with the aid of the accompanying drawings in which
Fig. 1 is an elevation partly in section of the improved apparatus complete.
Fig. 2 is a plan view of a detail of the construction, and
Fig. 3 is a detail view partly in section showing a modified form of construction.
Firstly, I seat the semi-globular receptacle or cup 1, in a suitable frame 2,
consisting of three curved radial arms carrying a ring 22, on the outer periphery
of which is an annular bead as shewn.

page_text: This frame is provided with a sleeve 3, carrying an annular shoulder 4, and a
bevel pinion 5, and turning in the arms 6 and 7, forming part of the casting or
standard 8.
Secondly, I construct the dome or cupola 9, and Hanged ring 21, of one solid
piece of glass or similar material the ring 21, being provided with a deep groove
to fit over the edges of the receptacle or cup and frame. The outer flange of this
groove is adapted to rest on the annular bead round the frame, and is provided-with
notches or recesses 12, which engage in corresponding lugs 13, formed on the ring
of the frame whereby the dome or cupola partakes of the rotary or swivelling
movement of the frame. Round the base of the dome or cupola is an annular
cavity 10, provided with perforations 11. This cavity forms a receptacle into
which, in the operation of the apparatus, the fruit juice flows, and from which it
passes through the perforations into the receptacle or cup underneath as presently
described.
Thirdly, I provide the receptacle or cup with a downwardly directed tubular
shank 14, which passes through the sleeve 3, and discharges into a goblet 15,
placed underneath.
Fourthly, I impart a reciprocating rotary, or swivelling motion to the super-
structure (i.e. the sleeve 3, the receptacle or cup 1, and the dome or cupola 9,)
by means of a segmental bevel wheel 16, mounted on a horizontal shaft 17, and
worked by a hand-lever 18.
By moving this hand lever to and fro a reciprocating rotary, or swivelling motion,
in a horizontal plane, is imparted to the superstructure.
A modified mode of working the apparatus is shewn in Fig. 3 where, instead
of the bevel gear 5, and 16, a lever handle 19, is substituted which is keyed to the
sleeve by a set screw 20, and the forward and backward motion of which produces
the necessary swivelling motion.
The operation-of-the improved -apparatus as "herein described will be readily
understood when taken in connection with the action of the apparatus described
in the specification of the above recited Letters Patent.
It will thus be seen that I provide a simple and effective apparatus for the
purpose in view and one, which in addition to extracting the juice, also strains
the same, and separates the seed and pulp therefrom.
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 1
claim is:
First In the operation of pulping fruit and extracting the juice therefrom,
an apparatus comprising a standard S, provided with two parallel projecting
arms 6 and 7, a sleeve 3 mounted in said arms and adapted to turn therein, a
beveled wheel 5, mounted on said sleeve, gearing with a segmental bevel wheel 16,
carried on a horizontal shaft 17, a cup shaped frame 2; connected with the upper
end of said sleeve, a semi globular receptacle or cup 1, mounted in said frame
and adapted to turn therewith, said semi-globular receptacle or cup being pro-
vided centrally with a tube 14, which passes downwardly through the said sleeve;
and a dome or cupola 9, mounted on the said receptacle or cup and provided
round its base with an annular cavity in the bottom of which are perforations,
substantially as shown and described.
Second: In the operation of pulping fruit and extracting the juice therefrom an
apparatus comprising a suitable standard S, a vertically arranged rotatable
sleeve 3, mounted in said standard, a semi globular receptacle or cup 1, mounted
above said rotatable sleeve and adapted to turn therewith, said receptacle or cup
being provided with a tube 14, at its bottom, which projects downwardly through
said sleeve, and a dome or cupola provided with an annular cavity at its base, the
bottom of which is perforated, substantially as shown and described in the accom-
panying drawings.
Third: The combination and arrangement of parts constituting my improved

page_text: fruit pulping and juice extracting apparatus constructed, and operating, sub-
stantially in the manner herein described and illustrated in the accompanying
drawings.
