Improvements in Lemon Squeezers.
1, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of this Invention (a communication to me from
abroad by Charles Benson Badeau, James Lyles Neefus, and Daniel O'Reardon,
trading as the Easley Manufacturing Company, of the City, County, and State of
New York, United States of America) to be as follows:-
This Invention relates to an improved lemon squeezer by means of which the juice
may be thoroughly extracted free from the oil of the skin and without liability of
the pulp and seeds passing away with the juice into the tumbler or other receptacle.
The squeezer is composed of an upright or standard, adapted to be clamped to a
table or other support, provided with a ring bracket projecting from the standard at
about mid-height and at its upper part formed with a forwardly extending arm
through which a hand screw extends, said screw being provided with a wire frame
adapted to receive and hold the cut portion of the lemon.
The lemon is held and squeezed between this frame and a solid piece of semi-
ovoid form which is supported by the ring bracket aforesaid, the wire-frame
constituting, as it were, one jaw of an ordinary squeezer and the semi-ovoid piece the
other jaw. This piece is formed in one with a circular frame which has concentric
strips connected together in such manner as to form through openings of wedge
shape so that the pulp and seeds will be retained while permitting the flow of the
juice. The exterior surface of the semi-ovoid piece or jaw has a series of projections
with intersecting grooves so as to present a rough surface. The frame is slotted and
flanged so that it may rest on the ring frame of the standard and it is furnished
with a handle.
In lieu of the wire frame, I may employ a forked frame in which the lemon will
be wedged and prevented from turning with the screw, by the edges of the fork
being sharpened or provided with points, or this frame may be of cup form with ribs
and with orifices, by means of which the lemon may be dislodged after it has been
squeezed. The upper end of the hand screw is plain and a spring is placed between
the standard and the handle of the screw so as to obtain a yielding pressure at the
end of the squeezing operation, and so avoid forcing out the oil of the peel.
The frame or lower jaw may be provided with a flange adapted to rest on the
edges of glasses of different sizes instead of resting on the ring frame of the standard
as above described, or with a downwardly extending rim adapted to enter the glass.

COMPLETE SPECIFICATION.
Improvements in Lemon Squeezers.
1, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of this invention (a communication to me
from abroad by Charles Benson Badeau, James Lyles Neefus, and Daniel O'Reardon,
trading as the Easley Manufacturing Co., of the City, County, and State of New

page_text: York) and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
- This Invention relates to a device for extracting the juice from lemons; and has
for its object to provide an apparatus for this purpose by means of which the juice
may be entirely extracted from a lemon and will be free from the oil of the skin, and
the pulp and seeds caught up without impeding the flow of the juice.
The Invention consists in an apparatus for this purpose and in details of construc-
tion as hereinafter described and claimed.
Reference is to be had to the accompanying drawings, forming part of this
specification, in which figure 1 illustrates the invention in position for use; Figure 2
is a plan view and Figure 3 is a vertical section of a part of the apparatus which
. disintegrates the pulp and retains it and the seeds. Figures 4, 5, and 6, represent
modifications of the lemon holder. Figure 7 is a vertical section of a modification
of the disintegrator and pulp and seed retainer, and figure 8 is a vertical section
shewing a further modification thereof. Similar figures of reference indicate corre-
sponding parts in all the views.
In carrying out this invention, I provide a suitable standard 1 which may be
mounted on a base or, as here shewn, is preferably secured to the edge of a table 2 or
other support by means of the arms 3 and set screw 4. The standard 1 is formed
with a bracket consisting of a ring 5 and arm 51 and located at a suitable height on
the standard so as to permit a glass, as 6, or other suitable receptacle to be placed
beneath it. The upper portion of the standard is formed with an arm 7 extending
over the ring bracket and provided with a screw 8 having an operating handle 9
at its upper end and a wire-frame 10 at its lower end adapted to receive the cut
'portion of a lemon and by the spring action of the wire serving to hold the portion
of the lemon.
A device for disintegrating the pulp of the lemon and at the same time retaining
it with the seeds while the juice is permitted to flow freely, consists of a frame 11
preferably formed with an oval central vertical portion 12 and concentric strips 13
connected together and to the central portion 12 by strips 14 and thereby forming
slots 15. The slots 15 are tapering in depth, so as to he narrower at the bottom 16
than at the top, thereby retaining pulp and seeds and permitting the flow of juice.
The central portion is formed with a surface 17 so constructed as to present a rough;
surface, consisting of a series of projections 18 forming intersecting grooves 19.
here shewn, the projections 18 are formed with facets, but they may be of any other
irregular shape. The outer concentric strip 13 is provided with a flange or
support 20, to permit it to rest on the ring 5, and is formed with slots 21 by means
of which it may fit over the arm 5. The frame 11 has a handle 22, by means of
which it may be placed upon and lifted from the ring 5. The frame 11 may rest
upon the top of a glass, if desired, instead of on the ring 5.
As
To operate the device; the cut portion of a lemon is pushed into the wire frame 10,
and the frame 11 being in position on the ring 5, two or three turns are given to the
handle 9, which, by reason of the size and pitch of the thread of the screw 8, will
cause the lemon in frame 10' to be pressed against the central portion 12 and to be
revolved thereon. The pressure of the lemon in the wire frame 10 will cause it to be
wedged in the frame and hold fast, to turn on the projection 12. The lemon
revolving on the roughened surface of the projection 12 the pulp is torn and
disintegrated thereby and the juice runs down through the grooves 19 and the inner
slot 15 into the tumbler. The pulp and seeds will collect in the inner slot 15, and as
the latter becomes too clogged up for the juice to pass, the juice will flow over the
collected pulp and down through the outer groove 15. Before the pulp and seeds
have accumulated to clog up both slots 15, all the juice will have passed through to the
tumbler. Upon raising up the frame 10, the lemon skin may be pushed out of the
wire frame and the frame 11 containing the pulp and seeds is lifted off the ring 5 by
means of handle 22, and the contents thrown away. It is obvious that the frame 11
may rest on the top of a glass instead of on the ring 5 and that the lemon may be
turned on the central portion 12 by hand instead of by means of the frame 10,

page_text: screw 8, and handle 9. In lieu of the wire frame 10, I may employ the frame shewn
in figure 4, consisting of arms 24 with sharp edges 25. The lemon will be held by
pressure within these arms and prevented from turning therein, the edges 25, together
with the lemon wedging between the arms 24, serving to hold the lemon in place and
prevent it twisting therein.
To avoid downward pressure at the close of the rotation of frame 10, I provide a
spring 251 secured to standard 1 and through which the screw 8 passes. The
screw 8 being plain at its upper end 24 will cease to act upon reaching that
point and the shoulder 91 of handle 9 bearing against spring 25 a yielding
pressure will be obtained and the frame 10 rotated without descending farther.
By this means the peel is prevented from becoming unduly jammed and the oil
thereof forced out. Any other forin and arrangement of spring may be used in
in connection with screw 8, to obtain the same effect.
Figure 5 is another modification of frame 10 in which the arms 24 are provided
with points 26 instead of the edges 25. Figure 6 represents another modification
of frame 10 consisting of an inverted cup 27 with interior ribs 28 and points 26
and holes 29 by means of which the lemon skin may be pushed out of the cup by
the finger.
In figure 7 a modification of frame 11 is shewn in which a flange 30 is provided to
rest on the ring 5 or the top of a glass and adapted to glasses of different widths at
the opening. Figure 8 is another modification of frame 11 in which a supporting
flange 31 is provided, and a depending portion 32 which projects into the tumbler.
These frames, as well as frame 11, may have a lifting-handle. Instead of two
slots 15, but one may be employed, but two are preferred as being more effective.
By constructing the lemon-holding frame with vertical ribs having spaces between,
the lemon is not only firmly held from turning therein by its skin bulging between
the arms, but the skin can also be readily pushed out of the frame.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
:-
1. In a lemon-juice extractor, a clamp for holding a piece of lemon consisting of
a rotary frame having vertical curved arms or ribs between which a lemon may be
wedged, with openings between the arms by means of which the lemon skin may be
dislodged from the frame, substantially as shewn and described.
2. In a lemon-juice extractor, a clamp for holding a piece of lemon consisting of
a rotary frame formed with an inverted cup 27 with interior vertical ribs 28,
