THOMAS JOSEPH KENT Licensed Victualler 187 Malpas Road Brockley S.E.,
and ALEXANDER KELVIE Machinist 187 Malpas Road Brockley S.E., do hereby declare
the nature of this invention to be as follows:-
This stand or bracket, juice extractor, is for lemons or other fruit. The head of
this extractor is made and ground the shape of the lemon itself, and by pressing the
fruit downward upon the head and turning right and left will cause the juice to run
freely through the strainer which retains the pulp and pips, giving free access to the
juice through the perforated dish which is also removable from its suspension in its
stand or bracket for washing. Can be screwed to the counter or made portable and
suit any size glass. Made in any metal, china, glass, earthenware, wood, and
the like.

COMPLETE SPECIFICATION.
An Improved Juice Extractor for Lemons and other Fruit.
We, THOMAS JOSEPH KENT, of 187 Malpas Road, Brockley, in the County of
Kent, Licensed Victualler, and ALEXANDER KELVIE, of the same address, Machinist
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:-
The object of our invention, is the construction of an improved apparatus for
extracting the juice from lemons and other fruit, in a rapid and effectual manner.
In the accompanying sheet of drawings, Fig. 1 is a side elevation, partly in section,
of the complete apparatus, as arranged to be secured to the edge of a bar, counter, or
table; Figs. 2 to 6 are detached views of the several parts, and Fig. 7 is an elevation
of a modified form of the apparatus arranged on an independant stand.
Similar letters refer to similar parts throughout the drawings.
In Figs. 1 to 6, A is a bracket provided with a screw clamp B to secure it to the
edge of a bar, counter, table, or other convenient place. C is an upwardly projecting
arm terminating in a tapered square shank C, to receive the extractor E. Fig. 3 is a
side elevation, and Fig. 4 a plan of the underside of the said extractor. As shewn in
the drawings it consists of a hollow metal cone, curved to fit the interior of the half of
a lemon and formed with grooves and cutting edges on the exterior, and provided
internally with a socket F to fit on the shank C₁of the bracket A.
D is a ring
attached to the bracket to support a dish or saucer H, Fig. 5, having a central
aperture H¹, and carrying a loose removable strainer consisting of a perforated
Hisc J, Fig. 6.
The action of the apparatus is as follows:-The half of a lemon, or other fruit, is
pressed down upon the extractor E by the hand and twisted right and left thereon.
The cutting edges of the extractor remove the whole of the pulp, core, juice, and pips,
eaving nothing but the mere rind or skin. The juice escapes freely down the deep

page_text: grooves of the extractor and together with the pulp, core, and pips, falls into the dish H.
The juice runs off through the aperture H¹ into a tumbler or other vessel placed
underneath while the pulp, core, and pips are retained by the strainer J. Instead of
the half of a lemon being operated upon, as above described, an entire lemon can be
treated if desired, by cutting off the tip of the fruit and entering the extractor upon
the exposed end, the whole of the juice will be extracted in as efficient a
though the two halves had been separately treated.
manner as
In the modified form of the apparatus shewn in Fig. 7, K is a wooden or metai
base supporting a frame L. This frame is provided with an upright piece (), to carry
the extractor E, and a ring D to carry the dish H, with its strainer. The action is
the same as before, and the tumbler to catch the juice is placed upon the base K.
Various modifications may be made in the construction of our apparatus, without
departing from the essential principles of the invention.
Thus, for example, we do not confine ourselves to the particular pattern shewn of
the bracket A, or the stand K with its frame L. It may be noted however that the
upright C on the bracket A, and the top part of the frame L, must dip downwards, as
shewn, so that any juice which falls thereon, will be guided downwards to
the dish H and thus will not run over the bracket or down the sides of the frame.
The extractor E may be solid, instead of hollow, and may be made of glass, earthen-
ware, wood, or other suitable material in place of metal. Extractors of different sizes
and shapes to suit varying sizes and shapes of fruit may be provided to fit on the same
machine. The dish is preferably made of glass, or earthenware, but may be of wood,
plated or enamelled metal or other suitable material. The strainer J is preferably
made of metal, plated, or enamelled. The apparatus acts with great rapidity, and
completely removes the juice from the pulp without extracting the oil or juice of the
rind, a fault inseparable from the ordinary squeezing machine, where pressure is
applied to the fruit by means of a screw or lever. The extractor E never becomes
choked, and the dish H and strainer J will hold the pulp &c. from several lemons, so
that a number can be treated one after the other without stopping to empty the
apparatus. The extractor E, dish H, and strainer J can be removed, cleaned and
replaced in a few seconds whenever required.
We do not make any claim to the construction per se of the grooved
extractor E, as we are aware that juice extractors of a similar form have been
heretofore employed, but having now particularly described and ascertained the
nature of our said invention and in what manner the same is to be performed
we declare that what we claim is :-
1. In an apparatus for extracting juice from lemons and other fruit, the com-
bination with a grooved extractor E, of a removable dish H with aperture H', and
a removable strainer J, substantially as set forth.
2. In an apparatus for extracting juice from lemons and other fruit, the com-
bination of a grooved extractor E, dish H and strainer J, with a bracket A, having
a screw clamp B, for supporting the said extractor, dish, and strainer, substantially
as set forth.
3. In an apparatus for extracting juice from lemons and other fruit, the com-
bination of a grooved extractor E, dish H and strainer J, with a stand K and
frame L, for supporting the said extractor, dish and strainer substantially as
set forth.
4. In an apparatus for extracting juice from lemons and other fruit, the combina-
tion, with a grooved extractor, of an arm C, with shank C, for supporting the said
extractor, substantially as set forth.
5. In an apparatus for extracting juice from lemons and other fruit, the combina-
tion with the dish H of a strainer J, substantially as set forth.
6. In an apparatus for extracting juice from lernons and other fruit, a removable
dish H and strainer J, supported in a ring D, substantially as set forth.
