page_text: I, JAMES COOMBER, of Chicago, County of Cook and State of Illinois, United
States of America, Gentleman, 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:-
1
The present invention relates to lemon-squeezers and more particularly to
that class which may be conveniently secured to a counter, table or shelf, and the
object of the invention is to provide a construction which is simple, efficient and
may be quickly operated.
The invention consists in the several novel features of construction hereinafter
described, illustrated in the accompanying drawings and more particularly
defined by claim at the conclusion hereof.
In the drawings: Fig. 1 is a view in front elevation, of a lemon-squeezer
embodying the invention. Fig. 2 is a plan view. Fig. 3 is an end elevation.
Fig. 4 is a view in vertical longitudinal section on line 4-4 of Fig. 2. Fig. 5
is an end view, the bracket for sustaining the receptacle for the juice being shown
in section. Fig. 6 is a perspective of the bracket, and Fig. 7 is a perspective of
a corner thereof.
A denotes a supporting frame having an arm a extended downwardly there-
from. The supporting-frame A is designed to rest upon a table or shelf adjacent
the edge thereof and its arm a is projected laterally as at a¹ and is provided with
a jamb-screw B, having a thumb-piece bat its lower terminal and a washer b¹
at its upper terminal. Jamb-screw 13 engages the underside of the table or shelf
and secures the supporting frame A to the table or shelf.
C denotes a holder or cup in which the lemon from which the juice is to be
extracted is placed. The holder is provided with an ear c at the back thereof
which is pivotally secured by a pin or rivet c¹ to a lug a² on the supporting-
frame. The underside of ear c rests as at upon the supporting frame A to
restrict the movement of the holder C about its pivot and retain it opposite and
aligned with a follower D. An arm a³ is extended from the supporting frame
and against this arm the holder will abut when pressure is exerted against the
holder C by the follower D. Arm a relieves the pivot pin c¹ of distorting strains.
The holder is cut away or notched as at 3 to afford an exit for the juice. Arms a
and a project forwardly from the supporting-frame and have mounted therein
a shaft E to the inner end of which a follower D is rigidly secured. The

page_text: follower D is provided with a cone d which is adapted to enter the holder and a
rim or annular flange d', as well understood in the art.
A cam F and lever G-preferably formed integral-are secured to the follower-
shaft between the arms or bearings a¹ and a³ by a pin f. Cam F serves to effect
the axial shift of the follower-shaft, and lever G serves to impart rotation to the
shaft, and being conjointly shifted, the lever and cam effect a gyrating move-
ment of the shaft E and follower D. The cam F comprises a hub fl; a spiral
cam-edge for advancing the follower, and a spiral cam-edge f³ for retracting
the follower. Cam edges f2 and f³ are designed to engage respectively arms a
and of the supporting frame. Arm a is provided with a friction-roller a
against which cam-edge will impinge when the lever G is operated to advance
the follower. Cam edge f4 engages arm a' as at a when the lever is shifted to
retract the follower. Lever G projects, normally, rearward from the supporting
frame and is provided with a handle g. A shoulder f* on cam F engages arm a
of supporting frame A to retain the lever and handle normally within convenient
reach of the operator.
A detachable shelf or bracket H upon which a suitable tray or receptacle for
receiving the juice may be placed, is supported in arm a of the supporting frame
below the holder and follower and in close proximity thereto. Shelf H is pro-
vided with guard ribs h and h¹ and adjacent one of its corners with a dove-tailed
tongue or rib h³ which fits into a groove as formed in arm a of the supporting
frame. Guard rib terminates in a shoulder h³ which engages the arm a and
properly positions the shelf beneath the holder and follower.
In operation, the holder is swung upwardly and transversely to the position
shown in dotted lines in Fig. 5, when a portion of a lemon can is put therein and
held until the holder is returned to its normal position, aligned with the follower,
when the projecting cone of the follower will hold the lemon within the holder.
The handle g of lever G is then grasped by the operator and turned forwardly to
rotate the follower-shaft. Such movement of the lever causes cam-edge få to
engage friction roller a6 and simultaneously advance the follower shaft E, and
impart a gyrating movement to the follower and force the cone d thereof into
the holder C and thus firmly compress the lemon in the holder. The juice
escapes through notch c into a receptacle on shelf H. As the lever G is returned
to its normal position, cam-edge f will engage arm a at a² and retract the cone d
of the follower from within the holder and permit the holder to be swung back-
wardly and the lemon to be removed from the holder.
It will be observed that the holder C is pivotally mounted in the supporting
frame, and arranged to be swung in a vertical transverse plane, and at a right
angle with the axis of the follower. This construction and arrangement is
advantageous, because the holder can be located close to the follower-cone, so the
lemon when placed within the follower can be retained therein by the cone
without first advancing the follower, inasmuch as the movement of the holder is
in a plane parallel to the face of the portion of the lemon as usually cut. And
farther because the close arrangement of the holder and follower, shortens the
necessary axial shift of the follower.
The cam and lever afford means for shifting the follower which can be quickly
operated. A half turn of the lever usually suffices to shift the follower sufficiently
into the holder. Manifestly such mechanism can be much more quickly operated
than the screw-shaft heretofore used 'and is more simple and inexpensive of con-
struction.
The purpose of providing a detachable shelf or bracket for sustaining the
receptacle or tray shown in dotted lines in Fig. 1, is to enable a tumbler of any size
to be held close to the holder and follower, when it is desired to discharge the
juice directly thereinto. It is customary to provide a tray to receive the juice
when a large quantity is being extracted and when the operation is continuous.
The mouth of the receptacle must be close to the follower and holder, otherwise
the spray would not pass into the receptacle. When it is desired to discharge

page_text: the juice directly into a tumbler or receptacle, other than the tray, the shelf may
be withdrawn from the grooves in the arm a of the supporting-frame and a
tumbler of any shape or size may be held in proper position below the holder
and follower.
The supporting-frame with its arm a can be adjusted adjacent the edge of a
table, counter or shelf of any thickness by jamb-screw B and secured in position.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
