WILLIAM O. DUNLAP, OF GEORGE'S CREEK, TEXAS.
LEM ON-SQU EEZER.
SPECIFICATION forming part of Letters Patent No. 439,327, dated August 12, 1890.
Application filed January 18, 1890. Serial No. 337,376. (No modelTo all whom it 7n ay concern:
Be it known that I, WILLIAM O. DUNLAP,
a citizen of the United States, residing at
George's Creek, in the county of Somervell
5 and State of Texas, have invented a new and
useful Lemon-Squeezer, of which the follow-
ing is a specification.
This invention has relation to improve-
ments in lemon-squeezers, and among the ob-
io jects in view are to provide a machine adapted
to cut or halve a lemon and extract the juice
therefrom and cast away the rinds at one and
the same operation.
A further object of the invention is to di-
r5 rect the juice of each half through separate
channels, whereby two glasses may at the
same time receive their proportionate allow-
ance of lemon-juice to be subsequently con-
verted into lemonade. Although Ihave here-
20 in mentioned the device as particularly adapt-
ed to the cutting and squeezing of lemons,
yet it will be apparent that the same maybe
used to advantage for similar operations upon
other fruit.
25 With these general objects in view the in-
vention consists in certain features of con-
struction hereinafter specified, and particu-
larly pointed out in the claims.
Referring to the drawings, Figure 1 is a
30 perspective of a lemon-squeezer constructed
in accordance with my invention. Fig. 2 is
a longitudinal vertical section of the front
portion of the same; Fig. 3, a transverse sec-
tion through the juice-cup; Fig. 4, a detail in
35 perspective of the juice-cup; Fig. 5, a similar
view of one of the strainer-plates.
Like numerals of reference indicate like
parts in all the figures of the drawings.
The base 1 of the machine may be of any
40 suitable construction, and is provided at its
rear end with a vertical standard 2, having
an opening 3 near its upper end, in which
upon a rod 4 is pivotally mounted the rear
end of a lever 5, extending longitudinally over
45 the base and through a slot 6, formed in a
vertical standard 7, at the front end of the
base and terminating beyond said standard
in an ordinary handle or hand-grip 8. An
opening 9 is formed in the hand-grip, through
50 which is inserted a ring 10, (see dotted lines,)
which may be loosely connected with an op-crating-rod 11, the lower end of the rod being
pivoted to an ordinary foot-lever 12, by which
said handle and lever may be depressed by
foot-power to perform the operations herein- 55
after described. A rod 13 projects from the
base, and at its upper end extends through an
opening 14 formed in the lever and between
the lower edge of the lever and the base, and
encircling the rod is a coiled spring 15, said 6o
spring serving to normally maintain the le-
ver in elevated or raised position.
In rear of the standard 7 and directly un-
der the lever 5 there is formed in the base a
pair of diverging-openings 16, each-of which 65
is provided with a discharge orifice or nipple
17, projecting below the base, an opening 16
being located at each side of the vertical path
traveled by the lever 5. That portion of the
base occurring between the openings 16 is 7o
provided with a vertical slot 18, in which is
seated the butt of a vertical stationary blade
or knife 19, the upper or cutting edge of
which is preferably curved or V-shaped,-a
shown. 75
Encircling the opening 16 is a cylinder or
ring 20, provided at diametrically-opposite
sides with internal recesses 21 for the recep-
tion of the ends of the knife, and above said
ring or cylinder projects the cutting-edge of 80
the knife. The upper edge of the ring is in-
ternally flared, and slightly below its edge is
provided with an annular recess or shoulder
22, subdivided, as is also the ring, by the ver-
tical knife. 85
23 represents a pair of semicircular perfo-
rated straining-plates of a size adapted to fit
at each side of the knife or blade and within
the recesses formed in the ring. The plates
are perforated, and their upper surfaces are 90o
concaved and form a continuation of the
flared upper edge of the ring, so that the two
combined are adapted to receive the half of
a lemon. The lever 5 is provided with a re-
cess 24, into which the cutting-edge of the 95
blade is adapted to take when the lever is de-
pressed, and at each side of the recess the le-
ver is provided with a convexed squeezer 25,
each adapted to take into and substantially
conform to the perforated straining-plates, toc
which latter, it will be understood, may be
readily removed for the purpose of cleaning.
