LEMON-SQUEEZER.

Specification of Letters Patent.

Patented NOV. 14, 1911.

Application led July 12, 1911. Serial No. 638,121.

To all whom it may concern:

Be it known that I, CHARLES L. KEE, a

citizen of the United States, residing at v 'of the device,

Portsmouth, in the county of Norfolk and State of Virginia, have invented new and useful Improvements in Lemon- Squeezers, of which the following is a specification.

This invention relates to devices for crushing fruits and vegetables and for expressing juices therefrom,'and has for its object to provide an eficient means for reciprocating and rotating a plunger in coperation with a bowl colander.

An important object is to provide an improvement on the usual two-lever lemon squeezer whereby the plunger head may be rotated to eect a shredding and tearing of the membranes and vesicles, this rotative action of the plunger being produced, if desired, during its reciprocation, whereby less force needs to be applied to the levers than would be required'if the plunger were operated without rotation. Furthermore it is the purpose to enable this operation without necessity for removal of the hand of 'portion 14, there is a plate 2O having upthe operator from either lever handle. I am aware that devices have been constructed in which a rotatable head was mounted in onelever of this type, but in these it has been necessary for the operator to release the grasp on one lever and a separate element operated for rotation of the-head, the two levers being pressed together as well as possible with one hand while the other is used to rotate the head. Also, I provide' means for rotation of the head before and after reciprocation of the plunger when necessary, which is of great value in the latter case, in insuring the breakage of all the juice vesicles after the compressing stroke of the plunger has been completed.

An important object is to present means whereby one lhandle of the device may be utilized as a lever, and twisted at will to rotate the head.

Another object is to provide a simple form of connection between the handle and head.

A further object is to give a simple form of construction, involving a minimum number of parts and operations in its manufacture and assemblage, and which may be produced at a low cost, by simple methods.

Other objects and advantages will be apparent from the following description and from the drawings, in which- Figure 1 is a longitudinal sectional view Fig. 2 isy a top view thereof,

Fig. 3 is a rear end View, Fig. 4 is a sectional View of a modification.

There is illustrated a squeezer comprising essentially two levers connected pivotally .at one end, one -10--being formed preferably of wood in which the broad inner :portion 11 having the foraminate bowl 12 is set therein and having the handle portion 13 suitably formed thereon. The other includes the base portion 14 hingedly connected to the lever 10 at the rear end, a bushing 15 being set therein concentric with the bowl when the two levers are in closed relation, and a shaft 16 engaged revolubly -therethrough. This shaft is headed at its `ilower end and has secured thereon the plunger head 17 formed preferably of lignum vitae, of which material the bowl is also preferably formed. Secured to the rear end of the lower lever 10 there is a hinge leaf 18. Secured upon the upper side of the base turned ears 21 spaced longitudinally of the fdevice, the rear portion of the plate being laterally enlarged and extended rearwardly at each side in the form of two arms 22 hav- Qing hinge knuckles formed at their ends, Eengaged with of a suitable pintle coengaged between the three. The plate is suitably apertured to rethe hinge leaf 18 by means ceive the upper end of the shaft l'revolubly therethrough, the shaft projecting thereabove and having a rectangular t-enon 23 formed thereon upon which is engaged a suitable `gear 24. The shaft is threaded above the gear and a retaining nut 25 engaged thereon. The forward ear 21 is provided with an enlarged aperture revolubly therethrough the lever shaft 27 the forward portion of which is bent into a loop to serve as a handle, and the rear eX- tremity of which is vtenoned and engaged revolubly through a reduced aperture 28 in the rearmost ear 21. The outer portion of this tenon 29 is threaded and receives a wing nut 30 thereover, whereby the shaft is held removably in place. It will also be apparent that the plunger head may alsobe readily detached, which is of importance as such implements need to be cleaned often when 1n 26 receiving slidably and frequent use. Centrally of the shaft there is secured a sect-or 31 centrally apertured and receiving t-he shaft slidably therethrough, a set screw 31 being engaged therethrough and adapted to impinge against the shaft to hold it rigidly against relative movement. The sector is provided with t-he arcuate series of laterally projected rack teeth 32 meshing with the gear 24 for rotation of the head 17 when the shaft 27 is rotated. The sector is al-so provided with two check lugs projecting radially adjacent each end of the series -of rack teeth, and adapted to strike against the plate 20 at the moment the gear encounters the outermost teeth as they move inward theretoward.

It will be seen that the plate 20 serves the double function of a hinge connecting the block 14 and lever`10, as well as to support the operating lmechanism for the 4plunger head.

In Fig. 4t there is illustrated a modification comprising the casting 10 adapted to be secured upon a counter, having the duct chamber 33 with the downwardly directed spout 34 beneath which a glass may be set to catch the juices expressed. The wall of the chamber 33 on the inner side is plane and vertical and provided with a rabbeted opening 35 in which is set the colander 12. Above the chamber 33 the casting is provided with the vertical pair of ears 36 between which there is pivoted the arcuate lever arm 37 the outer end of which is adapted to swing into posit-ion before the colander 12 and is bored on an axis concentric with the colander when the arm is in such position. Revoluble in this bore is the levershaft 27 carrying inwardly of the arm the plunger head 17 adapted to engage properly within the colander, the shafthaving the collar 38 outwardly of and closely adjacent the arm to prevent reciprocation of the shaft therethrough. The outer end of the sha-ft is provided with a suitable handle 39.

In the operation of the first described form of the device, the two levers are grasped in separate hands and separated for the introduction of afhalf lemon, a hemispheroid of which is presented with its plane side in the bowl 12. The handles 13 and 27 are then forced laterally toward each o-ther, and as soon as the compression of the lemon begins 'a slight rotative twist is given the shaft handle 27 by which the head 17 is rotated and the vesicles of the lemon rapidly broken and prevented from clogging the openings through the bowl. After the handles have been brought as close together as possible, several partial turns of the head may be given to insure the complete shredding of t-he pulp and expression of the juices. The rotation of the head in a lemon squeezer of this type is of especial value because of the fact that when the lemon is first emplaced it projects so far out ofthe bowl that the plunger engages it at a point eccentric to the axis of the bowl, tending to jam the lemon to one side to become wedged between the head and inner side of the bowl. By the rotation of the head, which may be accomplished to the extent desired, the position of the lemon may be so varied during compression as to maintain it centrally of t-he bowl throughout the ope-ration.

It will be noted that the head in each form of the device is peripherally grooved at intervals radially of the axis of rotation, whereby it is made to firmly engage the lemon to rotate it against the openings in the bowls. The bowl in the second form is provided with a number of downwardly extending grooves on its inner side adapted to carry a large part of the juices to the lower ,side of the bowl.

The second described form of the device ,is operated by one hand, the half lemon being presented in the bowl as before described while the lever shaft 27 is borne downwardly to force the pltmger head 17 against the lemon. In the initial stage of this operation one hand of the operator may be utilized to emplace a glass beneath the spout25, or the glass may be so held during the entire operation of expression. The head 17 may be rotated whenever, and to'any extent desired, by the twist-ing of the handle, as will be apparent.

It is an important advantage of these two devices that the head may be rotated in either direction, and alternately in both directions, while the full pressure of the hand is exerted upon the lever for compression. insuring the thoroughness of operation of the device.
