An Improved Fruit Pulping and Juice Extracting Machine.
I, CHARLES HUNT of 63 Ann Street in the City of Belfast and County of Antrim
in 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
ascertained in and by the following statement :-
My invention has reference, to the attrition of the soft and succulent parts of a
lemon or orange and to the extraction of the juice therefrom and consists in the use
of a special apparatus by which the straining of the pulp and removal of the juice of
the fruit may be accomplished in the same operation.
For this purpose I employ a bowl or semi globular receptacle having a recessed
rim and fitted with a broad flanged ring curved downwards towards its centre and
grooved underneath to receive and fit closely upon the recessed rim of the bowl or
semiglobular receptacle with an upwardly projecting conical dome or cupola and
strainer having vertical or slightly obliqued scraping ribs and grooves or corrugations
externally and surmounting and covering the central orifice of the flanged ring to
which it is attached.
The dome or cupola and strainer is provided with perforations round its base so as
to permit the extracted juice to percolate or drip into the bowl or receptacle but to
prevent the pips and pulp from passing down and I fix the flanged ring firmly upon
the bowl or receptacle so as to move along with it by the aid of a tongue or tongues
upon the flange of the ring passing into a relative groove or relative grooves in the
shoulder upon the rim of the bowl or receptacle.
The bowl or receptacle is furnished below with a socket and fixed removably by
means of a key or pin upon a vertical shaft set in a foot step and working in a journal
above and the whole superstructure is caused to vibrate rapidly backwards and
forwards in a horizontal plane by the use of a horizontal bevel wheel or segment
thereof carried by the vertical shaft in gear with a larger vertical bevel wheel or
segment thereof mounted upon a horizontal shaft and linked by a connecting rod and
crank with a rotating arm or disc which is operated manually by a lever or handle
attached to a shaft through the axis of the rotating arm or disc.
The shafts and bevel wheels or segments just mentioned are mounted upon a
suitable frame bolted or fixed to a rigid stand and supported in appropriate steps,
journals or bearings which frame also carries the arm or crank and the lever or
handle for operating the Machine.
The apparatus may otherwise be actuated by a lever or handle attached to the
horizontal shaft with a stop or stops to prevent its being rocked beyond the ends of
the segments.
And in order that my said Invention may be more fully understood I shall now
proceed to refer to the drawings on the sheet hereunto annexed the same letters of
reference indicating the same parts of the apparatus throughout all the figures on
the Sheet.
Fig I is a side elevation of my apparatus showing the bowl or receptacle with its
flanged ring and a tongue for holding same in position, the dome or cupola and
strainer surmounting the flanged ring, the vertical shaft and socket, the bevel wheels

and
Fig II is a front elevation partly in section showing the same parts as in Fig 1
and also the rotating arm.
a is the bowl or semiglobular receptacle with its recessed rim fitting into the
groove in the flanged ring, b, and c is the dome or cupola and strainer attached to
the ring, b, and having a circle of perforations, d, d, at its base; e is a tongue upon
the flanged ring, b, fitting into a groove in the shoulder at the rim of the bowl or
receptacle, a, and keeping the ring, b, and its attachment, c, in motion with the
bowl or receptacle, a; fis the socket and g is the key by which the bowl or receptacle
is removeably connected with the vertical shaft, h, set in the footstep, i, and working
in the bearing, k; is the horizontal bevel wheel or, segment carried by the vertical
shaft, h, gearing with m, the larger vertical bevel wheel or segment mounted upon a
horizontal shaft, n, and connected by a crank, o, and rod p, with a rotating arm, r,
which is operated manually by a lever or handle 8, attached to a shaft t, passing
through the axis of the arm, v; w is the frame upon which the parts above mentioned
are mounted.
The operation of the apparatus I have described is as follows:-The lemon
or orange to be pulped is divided into two practically equal end parts
each of which is placed with the division upon and forced gradually down over the
conical dome or cupola by the pressure of the operator's hand while he rapidly turns
the lever or handle with his free hand, vibrating the bowl or receptacle and the flanged
ring and conical dome or cupola through the segments of the bevel wheels until the
pulp is ejected.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed I would have it to be
understood that I do not claim as of my invention or the exclusive use of a bowl or
semiglobular receptacle, flanged and grooved ring and conical ribbed or corrugated
dome or cupola perforated round its base except where the same are specially
constructed actuated and employed in the manner and for the purposes hereinbefore
stated nor do I claim the use of shafts, bevel wheels, cranks, links, foot steps, sockets
and levers or handles nor any of the separate mechanical parts herein before described
or referred to but I claim
1. The use of a rotating bowl or receptacle flanged grooved and tongued ring and
ribbed or corrugated dome or cupola perforated at the base constructed actuated and
employed substantially in the manner and for the purposes hereinbefore described
and shewn in the drawings hereunto annexed, and
2. The combination and arrangement of parts constituting my improved fruit
pulping and juice extracting machine constructed actuated and employed substantially
in the manner and for the purposes hereinbefore described and illustrated by the
drawings hereunto annexed.
