to provide means in devices of the above type enabling adjustment of the length of stroke of the pressure head.

Finally, it is also an object of the present invention to resiliently connect the pressure head with the means sliding the same so as to obtain a resilient impact of the pressure head upon the stationary pressure member. 7

With the above objects in View, the present invention mainly consists of a juicer comprising in combination a juicer body, a shaft mounted within the upper part of this juicer body reciprocably in axial direction, a squeezing member secured to the front end of the shaft member, a rotatable worm gear rotatably mounted within the lower part of the above mentioned juicer body, a rotatable worm engaging this worm gear and mounted also within the lower part of the juicer body, motor means for rotating the rotate able Worm, an offset cam follower secured to one face of the rotatable worm gear rotatably together with the same, a rocker arm oscillatably pivoted at one end within the juicer body to the bottom portion thereof extending in upward direction, a cam slot arranged within this rocker arm so that the cam follower on the rotatable worm gear projects into the cam slot, and pivoting means pivotally attachingthe upper end of the rocker arm to the rear end of the shaft memher.

In accordance with a preferred embodiment of the present invention, a connecting rod is provided which is pivoted at one end to the upper end of the rocker arm and at the other end to the shaft member mentioned above. Furthermore, means are provided for adjusting the length of this connecting rod; this results in adjustment the shaft member as explained above.

Also in accordance with the present invention, it has been found advisable to provide resilient pressure transmitting spring means interposed betweenthe shaft member and the squeezing member so as to enable the shaft member to resiliently press the squeezing member against a stationary squeezing surface.

In order to obtain standstill of the pressure head, i. e. of the squeezing member in its extreme squeezing position, an elbow shaped cam slot is provided in the rocker arm which has an outer medial arc-shaped slot edge which has the same curvature as the path of the outermost point of the cam follower described above; this arrangement enables the cam follower to oscillate the rocker arm so that the same is at standstill for a short period of time when it reaches its final forward position. This results also in standstill of the squeezing member connected to and oscillated by the rocker arm in the extreme forward position of the same, i. e. when the squeezing member is inits forward squeezing position.

In order to enable eas removal of the pressure head from the operating means for cleaning purposes, these squeezing means comprise in combination a shaftmember mounted Within the upper part of the juicer body reciprocably in axial direction, a supporting rod mounted also within the upper part of the juicer body coaxially with the shaft member slidably in axial direction, a squeezing member at the front end of the supporting rod, sleeve means on this squeezing member fitting upon the front end of the supporting rod, pin and hole means easily detachably attaching the sleeve member together with the sleeve means and the squeezing member to the front end of the supporting rod, and pressure transmitting spring means interposed between the shaft member and the rear portion of the supporting rod so as to enable the shaft member to resiliently slide the supporting rod together with the squeezing member in' axial, direction.

minates, short ofthe end of thepouch shaped-z walled enclosure 55. The shaft I5!l.is axiallydisposed within a tubularsleeve I55 which serves as apushing means.

which is screwed, a capYI51. The cap I51 comprises an end wall I58 formed with an axial through opening I59 which admits the plunger shaft I53. Thecap I 51 further comprises an annular fiangedrwall It'llv which is internally threaded and engages the threaded portion I55 of the sleeve I55. Extending downwardly from the wall I33 area pair of cars IBI which are formed with aligned transverse openings I52. An annular'collar I63 is mounted on the shaft portion I 52 of reduced diameter abutting the. shoulder I53; A helicallycoiled spring I65 having a predetermined compression point, beyond which its normal-length is shortened, is mounted about the shaft-portion I52, occupying the annular space between the shaft and the sleeve I 55. The spring I65 :isinterposed'between the collar I53 and the inside surface of end ,wall I53 of cap I51. A pair of'hexagonal nuts I66 are screwed on the extcrnallythreaded end I61 of the shaft portion. I52 with theinner nut normally abutting the outer face of wall I58 of the cap I51. The sleeve I55 is mounted for'reciprocables movement in suitable bearings positioned in theopenings 28 and v 30 in walls 21 and29, respectively, in housing I I.

than the compression point of the spring. In this case, the rear end of the shaft portion I52 will extend through the opening I59 in the cap I51 while the sleeve I55 continues its forward movement. This avoids injury to the front wall 51 of the compression box as well as the block I30 and its associated actuating parts.

The above described arrangement is not very well adapted for adjusting the pressure of the spring I65. 1 ,1-

In order to enable such adjustment in the modification shown in Fig. 6 the cap I51 which is screwed upon the screw threaded end portion of sleeve I55 is provided with a relatively large screw threaded opening into which the externally screw threaded plug I 51' is screwed.

This plug I51 is provided with a hole into which projects the rear end of the shaft I52. Thus, this shaft is guided and supported by plug I51.

As clearly shown in Fig. 6, the rear end of the spring I85 abuts against the front face of plug I51. Furthermore, this plug I51 is provided at its rear end with a hexagonal nut I51, which is either firmly secured to the plug or made out of one piece with the same. i

In order to adjust the pressure of the spring I65 it is only necessary to turn the hexagonal nut I51' and to turn thereby, the plug I51 in the screw threaded hole in cap I51. Such turning of the plug I51 results in movement of the plug in axial direction of shaft I52, causing variation of the pressure exerted by the plug against the spring I65. Thus, by turning the nut I51, it is possible to easily adjust the pressure of spring I65.

Means is provided for imparting movement; to the plunger shaft I50 through the tubular sleeve I55 and its attached cap I51. To this end, an electric motor I10 is mounted in the recess 44 in the wall 42 of rear housing I2, being suitably bolted to the wall 43. Thearmature shaft In of the motor comprises an extension I1Ia thereof which extends horizontally through a bearing I12 mounted in opening 45 in wall 43 and projects into opening 38 on the wall 25 being supported in a bearing I13 mounted therein. On the extension Illa means are provided for rotating a rotatable driving member. According to a preferred embodiment of the inventiona worm I15 is suitably keyed to a forward portion of shaft extension Illa.

The worm wheel comprises a thickenedhub I80 which is formed with an axial annular recess I8I extending through a major portion of the thickness of the The recess I8I extends towards the boss 35. The hub I80 is further formed with an axial through opening I82 which communicates with the recess IBI and has a diameter less than that of the recess I8I thereby forming a shoulder I83. A ball bearing is mounted within the recess I8I. The bearing comprises an outer race I85 abutting the shoulder I83 and an inner race I85 receiving the shank ofthe stud I19, being disposed between the head of the stud and the projecting edge of the boss 35. The end I88 of the stud I19 which is of reduced diameter and is externally threaded, projects through the opening 38a in the boss 35a and has a cap nut I89 screwed thereon, with the nut abutting the boss 35a. A circular plate I90 formed with an axial opening I9I is screwed to the face of the hub I80 with the projecting end of boss 35 passing through the opening I9I. The plate I98 retains the outer ball bearing race I against axial movement. The usual balls I92 are disposed between the inner and outer races. The hub I80 of the worm wheel I18 is further formed with a transverse through bore I95 which includes an internally threaded end portion I98 of reduced diameter. The bore I95 is offset with respect to the axial recess Iill.

Means is provided for interconnecting the cap I51 on the sleeve I55 with a rotatable driving member, such as the worm wheel I18. To this end, a rocker arm 200 is mounted at its lower end on a shaft 20! which is suitably fixed in the openings 33, 34 in bosses 3!, 32 on walls I5, I8, respectively. The rocker arm 200 comprises an upwardly and outwardly extending web 282 of substantially rectangular cross section and having a transversely extending boss 203 at its lower end. The boss 203 is formed with an axial through opening 204 in which is received the shaft 20L A triangular shaped web section 205 extends transversely of the web 202, interconnecting the same with a top portion of the boss 1203. Extending upwardly from the upper end of web 202 is a cam portion 286. The cam portion 286 comprises an endless wall 201 which defines an elbow shaped transversely disposed cam opening or slot 208 on the inner portion thereof. The opening 208 is defined by a portion including a pair of parallel straight surfaces 209, 2I0 interconnected by a semi-circular surface 2I I at one end thereof, said opening being disposed above a horizontal median line. A similar portion is disposed below the median line, being angularly relatedto the portion above the line and in communication therewith. The surfaces 209 are interconnected by a convex surface 2I2 and the surfaces 2I0 are interconnected by a concave surface 2I3. This concave surface is arc-shaped and has the same curvature as the path of the outermost point of the cam follower 228; It extends over about 60 of the path of the cam follower, resulting in standstill of the rocker arm 200 while the cam follower 228 moves along this concave surface 2 I 9. Extending upwardly from the upper end of cam portion 208 is a short web 2 I4 which is formed at its upper end with a boss 2I5 provided with a transverse through opening 2I6. The arm 200 is pivotally interconnected to the cap I51 by means of an intermediate link 2 I 1 formed with transverse openings 2I8, 2I9 at the ends thereof. A headed bolt 220 extends through the opening 2I8 in boss 2I5 of the arm 200 and through the opening 2I8 on one end of the link 2I1 with a nut 22JI screwed thereon. The opposite end of the link is disposed between the ears I6I of the cap I51 with the opening 2 I 9 in registry with the transverse openings I62 in the ears. A pivot pin 222 extends through the registering openings and is suitably fixed with respect to the ears I6I.

The above mentioned intermediate link 2I1 is actually composed of three portions, namely the two substantially sleeve-shaped screw threaded end portions 2H and 2I1", and the connecting rod 2I1. This connecting rod 2I1" is screw threaded along its both ends and engages the screw threaded holes within the two screw threaded end portions 2I1' and 2H". By these means it is possible to adjust the total length of the intermediate link 2I1 and to adjust thereby also the length of the stroke of the plunger block I30.

A cam follower roller 225 is disposed in the cam opening 208 of the rocker arm 200 and engages the worm wheel I18. The roller 225 comprises a. shank 226 having extending from one end diameter 227 which is'screwed into the threaded portion I95 in the hub I80 of the worm wheel. Extending from the other end of shank 225 is an annular roller portion 228 of enlarged diameter which is disposed within the cam portion 256 of the rocker arm 200. Extending from the outer surface of the roller'portion 225 is an annular head 229 of enlarged diameter which spans the opposite walls 201 of the cam opening 208.

It is apparent that upon energizing the motor I10, the rotation of the armature shaft I'H will cause'the' worm I 75 thereon to impart rotary motion to the worm wheel H8. The rotation of the worm Wheel I78 will cause the cam follower roller 225 mounted thereon, to move within the cam opening 208 of the rocker arm 295 thereby imparting rocking movement to the arm about the shaft 20I as an axis. The rocking movement of the arm 20I will impart reciprocating movement to the sleeve I55 through the interconnecting link 2!! and cap l'5'I, thereby moving the shaft I50 and the attached plunger block I35.

'As mentioned above, the particular shape of the concave surface 2I3 of the cam slot 208 will result in periodic standstill of the rocker arm 250 "which, in turn, will result in periodic standstill of shaft I50and the attached plunger block I30. These periods of standstill will occur due to the particular arrangement of the parts of the new 'machine at those moments when the plunger block is in its forward compressing position.

Thus, thecompressedfruits will be subjected to extended'compression periods during which the juice iscompletelyextracted.

' Means is provided for regulating the movement "of fruit along the chute I0. To this end, an oscillatory trigger'230 is fixedly mounted on a pivot pin 23I which is journalled in apertured cars 55,

89 extending from the portion of thechute 0.

The trigger 230 comprises an upwardly extending arm 232 and a downwardly and 'rearwardly extending arm' 233 angularly related to arm 232. The arm 233 is formed with a horizontal bottom "edge 234. A stop plate 235, having side portions projecting on either side of arm 233, is fixed to the rear of the arm and is adapted to abut the bottom wall of chute portion'i2 upon movement of the trigger 230 in' a counterclockwise direction. The upper end of trigger arm 232 has aflixed' thereto a curved prong 235 by means of a nut 23! screwed onto the threaded rear end of the prong. The fore portion of the prong 236 "is'adapted to move through the slot 85 inthe bottom wall 84 of the chute portion "12 upon "movement of the trigger 230 in'a clockwise direction. The bottom edge 2340f the arm 233 is normally disposed in contact with the top face of a plate 240 secured to the top face of the plunger block I30 by screws received in the openings I38 therein. The side edges of the bottom face of the plate 240 are in slidable contact with liner strips 24! secured to the top edges of the side walls '56, 56a of the compression box 55.

Means is provided for insuring the restoration of the trigger 230 to its normal position after it has been rotated in a clockwise direction due to the forward movement of plunger block I30 and the plate 240. To this end, a substantially triangular shaped chambered cover member 242 is mounted on the chute portion 12 abutting the triangular shaped wall 90. The member 242 comprises a vertical wall 243 and a peripheral flanged wall 244 extending therefrom and contacting the wall 90. The rear end of pivot pin 2 3I extends collar 23Iafixed thereto. A stud'245 is fixed in the opening a in wall 90' and an aligned opening 243a in the wall 243. The stud 245 is in horizontal alignment with the-pin 23I with the end suitably secured to'the pin. It is apparent that upon clockwise'movement of the trigger 230, the windings of :spring 246 will tighten'about the' pivot pin. When the clockwise movement of the trigger 230 ceases, the spring will "tend to unwind thereby imparting counterclockwise movement to the trigger, thereby restoring it to its normal position.

An aligning'finger '250 is secured to thetop edge of the projecting portion 58 of the front wall 51 of the compressionbox'55, by means of a screw 25I received in an appropriate threaded blind opening in the projection'58. The finger 250 is aligned with the slot 59 and is adapted to properly position the bottom end of the guide 9|.

The aligning finger 2501s further adapted to overlie and contact the upper surface of plate 240 which is securedto the top face of the block I30, when the block is in its forward, compressing position. The finger 250 will thus keep the block I30 from moving upwardly during its forward movement towards wall 57 of the compression box.

A closure plate 252 is secured to the bottom face of the projection 58 on the front wall 51 of the compression box 55 thereby closing off the bottom of the slot 59.

In operating the device I0, fruit, vegetables, or the like of predetermined size are fed successively to the chute 10 along portion II thereof. The chute guide 9| is'adjustedwith respect to the chute portion 12 by turning the ball crank handle I02 in the appropriate direction. The adjustment of theiguide 9| is made in accordance with the size of the fruit to bev processed and insures smooth feeding of the moving fruit which passes between the inclined walls 84a of the chute por- 7 Simultaneously; the cut fruit will be squeezed between the front face I3I of the block I30 and the front wall 51 of the compression box, with .the forward edge of the blade I40 being received in thevertical slot 59 in the wall 51. The juice squeezed from the fruit-will go through the strainer plate I2I and will pass into the juice box IIO where it'will be directed by the converging sections I I4 of the bottom wall I I3 to the outlet I I5 where it may be collected in a container, not shown,- suitably positioned on the forward portion Me of base I4. The squeezed hulls of the fruit will move down the inclined strainer plate I2I and will pass the pivoted guard plate I21, moving it outwardly about itspivot'pin I2'Ia. The hulls may be collected in a suitable container or by other means, not shown.

wall 51. The ends" of the rods I 43, I 45 will act as -stop*members"to prevent" the squeezed hulls from moving rearwardly within the compression box 55 due to a tendency for the hulls to adhere to a slight extent to the cutting blade I40 or the front face I3I of the plunger block I30. The hulls will continue their downward movement until they contact the inclined strainer plate I2I in juice box I I0.

While the block I30 is in its forward compressing position, the trigger 230 will be rotated in a counterclockwise direction since the bottom edge 234 of the trigger arm 253 is no longer in contact with the plate 240 on the block and is urged by the action of the clock spring 246. In this position, the curved prong 236 will be in its rearward position and, therefore, out of the path of the fruit moving between chute portion 12 and guide 9|. Accordingly, another fruit may drop onto the plate 240 preparatory to being dropped into compression box 55 to be squeezed upon the retracted movement of the block I30. When the block returns to its rearward position, the trigger 230 is rotated in a clockwise direction bringing the curved prong 236 into its forward position thereby supporting the fruit above the prong and preventing downward movement thereof until the next forward movement of the block I 30.

It will be noted that the shape of the cam opening 206 in the rocker arm 200 provides for alternate fast and slow movement of the reciprocating shaft I 50. As the cam follower roller 226 approaches and leaves the angular portion of the opening 208 as defined by the surfaces 2 I2, 2 I3, the speed of movement of the shaft I50 is relatively low. When the roller 228 moves towards the end surfaces 2 II of the opening 208,

the movement of the shaft I50 is accelerated. It follows from a consideration of Fig. 1 that the shaft will be relatively slow moving at the rearmost and foremost positions and relatively fast moving intermediate these positions. This is particularly desirable when the shaft I 50 is at its foremost position where the object within the compression box 55 is being squeezed by the block I30 on the shaft I50, against the front wall 51, of the compression box. In this position the movement of the block is of an order that provides a slight hesitation or dwell. This insures efficient extraction of the juice from the body being squeezed. The retraction of the block I30 is at a relatively higher speed, as the roller 228 moves away from the angular portions of the cam opening 208. The speed of movement of the block is againslowed down as the shaft I50 reaches its rearmost position preparatory to change in direction of movement and accompanying acceleration in speed in its consequent forward movement.

In the event that an object is encountered in the compression box 55 which offers undue resistance to the movement of the plunger block I30, the shaft I50 will stop while sleeve I55 will compress spring I65. The compressive point of the spring is such as to permit stopping of the shaft I50 upon a predetermined degree of resistance to the forward movement of the block offered by the object within the compression box 55. s

The chute 10 may be readily removed from the housing I I by lifting it upwardly together with the stud 11, which is mounted on the bracket 22. The chute 10 may also be rotated by means of the stud 11 about the bracket thereby bringing the chute portion 12 into and out of its position with respect to the top of juice In Figs. 11 to 16 is shown a compression box 260 and attached juice box 26I, similar to the compression box 55 and juice box IIO, previously described, except as hereinafter described and illustrating a modification thereof.

The compression box 260, open at its rear, top and bottom, comprises a pair of side walls 262, 263 interconnected at their front ends by ill a pair of forwardly converging front walls 264. Extending inwardly from the upper edge of each of the side walls 262, 263 is a longitudinal, horizontally disposed strip 265. A triangular shaped top wall 266 interconnectsthe upper edges of the front walls 264, with the forward. ends of strips 265 abutting the same. Disposed in contact with the lower edges of the side walls 262, 263 are longitudinally extending flanges 261. The flanges 261 which project outwardly of the walls 262, 263 and also comprise a portion 261a projecting inwardly of the walls, extend forwardly of the forward ends of the side walls and slightly beyond the apex portion of front walls 264. The forward portions of flanges 261 are interconnected by a horizontal plate portion 268 having a forwardly disposed transverse edge 269. The compression box 260 is removably secured to the wall 29 of front housing II by means of transverse pins 63, passing through openings 60, 6| in Walls 262, 263 which register with openings 62 in wall 29, in the manner previously described.

A plunger block 215 is slidably mounted for longitudinal movement within the compression box 260, with its bottom side edges in contact with flange portions 261a. The block 215 comprises a pair of diverging rectangular shaped front faces 216 which complement the v-shaped front walls 264 of the compression box. Extending rearwardly from the outer ends of faces 216 are parallel side faces 211, 218 in sliolable contact with the inner surfaces of side walls 262,

263 of compression box 260. The block. 215 further comprises a vertical back face 280 disposed inwardly of the rear edges of the side faces 211, 218. A boss 28I extends rearwardly from a central portion of rearface 280. The boss 28I is formed with an inwardly extending axial blind end recess 282 for the purpose hereinafter appearing. The block 215 is further formed with a set of four horizontally disposed through openings 283 symmetrically disposed with respect to the axis of recess 282, as shown in Fig. 13.

Means is provided for reciprocating block 215 within the compression box 260. To this end, a plunger shaft I50a which is connected at its rear end to the operating mechanism illustrated in detail in Figs. 1 and 2, is detachably attached at its front end to the block. The plunger shaft I50a extends rearwardly through the opening 30 in wall 29 and has a forward portion 284 of re duced diameter projecting into recess 282 and forming a shoulder 285 which abuts the outer face of boss 28I. The shaft portion 284 is formed with an annular groove 266. The upper portion of the boss 28I is formed with a slot 281 extending parallel to the back face 280 of the block. The slot 281 communicates at its lower end with the recess 282.

Means is provided for releasably locking shaft I50a to the plunger block 215. To this end, a latch 290 is pivotally mounted at one end by means of pivot screw 29I on back face 280 of the block, adjacent the side face 218 of the block. The latch 290 extends through slot 281 in the boss 28I and is formed with an arcuate portion 292'on its bottom edge. The arcu'ate' e'dge' porwardly' of the free 'en'd'of arm 2 94- 'and is disposed in a horizontal-slot291 formedinthefreeend of latch 290. To disengageshaft I50a from block 215, it is only necessary to move arm 294 'in' a clockwise direction aboutpivot pin 295, which will cause latch 290-to be lifted upwardly, there- -'by disengaging the arcuate ed'ge292 of'the latch from the groove'286 in'the"shaftportion ztd of shaft I5Iia.

The through-openings-283 in block 215*admit the fruit support rods I43, I45 whicharesecured at their inner ends tothe wall 29-in-the manner previously described, their outerends terminating short of the walls 264-of'the compressionbox to leave'a space therebetween.

The block-215 comprises a rectangular shaped top plate 300 extending-from the top-'faceof the block rearwardly'of back face 2-8ll of-theblock and forwardly to-theapex portion of theconverging front faces 2'16of the block. "The plate 300 is connected to the top of block 215 byaneck portion-3M and extending between the strips 265. The side'edges 302 of the plate 300 overlie the strips 265,-as shown in Fig. 13. The undersurface of areas portion ofpl'ate3'l10 is connected to the backiace 28B oftheblock by a web 383. The groove formed-by the neck 30I,"and the side edges 362 of the plate 300', receiving the inwardly projecting portions of strips 2-65,'-"permit slidable' movement of the-block" 215 whilepreventing upward movement thereof. When the block is in the forward position, the front portion of plate 306 will be disposed over the top plate 253 of the compression box.

The juice box 26I which is open at the=top and front comprises a downwardly and forwardly inclined back wall 3Il fromwhich extends a pair of side walls'3l I. The side walls 31 I areformed with inturned curved edges-3I2 -at their upper ends, said curved edges 'slidably engaging the flanges 251 on the bottom'of'the 'sidewalls'of the compression box260 whereby to 'removably position the juice box on the compressionpox. The juicebox further comprises a bottom'wall 3 I 3 slightly inclined upwardly and forwardly,

interconnecting thelower ends of side walls3II and the back wall' 3H3. The bottom wal1"-3I'3 is formed witha centrally disposedspo'ut opening 3M adjacent the-back-wall '3I0. Theforward turned transverse portion 3l5. A strainer member (H6 is removably mounted'within the juice The same comprises a bent plate '3I1 extending between the side walls 3| I of the juice box. The plate 3I1 comprises 'a portion 3I8,'3I8a portion of plate 320 and is adapted-'to -engage an inner portion ofthe-upturnededge' -3 I 5-on bottom-wal1 3I3 of the juice'box. -The-"edge'of the other angle portion 3 I 8a of the plate 31 1' 2 abuts' an: upper portion ortheback wall 3 I 0 of the juice box. '"In this 'position', the wiresor rods 3 I 9 are disposed in "a diagonalposition 'relative to the'upper' edges of. the box. A rectangular guard 1 plate 322 extends between the I side walls 3II-of the juice box, being pivotally mounted for outward movement at its upper edge'ona tr ansverse pivotpin' 323 'removably disposed in -aligned' notches 324 formed in the forward upper ends of sidewalls 33 I I. The lower-edge of the plate- 322 may abut the wires 3I9 offthe strainer "-"3I6 when the": plate is'in its normal verticalposition. "A stud 325 is" mounted onthe plate 2322 for movmg the same.

It isnote'd' thatthe sidewalls 2G2, 263' Of 'the 'compression box' have their top edges somewhat 1 higherthan the topedges of the compression box 55irel'ative to the upper edge of wall 29as shown -''in Fig. '1, in order-to accommodatethe lock' plate 300. 'Accordingly, the chute 10 which'feeds the fruit to the compression' box, may be raised to a suitable-position,in the manner-previously described.

i The constructionshown inFigs.' 11 to 16' facilitates'theremoval of juice box I from compression box 260,for cleaning or the' like. Similarly,

the strainer '3I6 and'the plunger block 215 may be readily removed for cleaning or the like. Also,

the converging 'faces'21B-on the plunger block 215 are highly effective in compressing the obbetween the endsof support rods I43, I and the wallsi'264 to the strainer- 3I6 where they are guided through the movable guard plate 322 to the outside of the juice box.

'In'Fig.- l8, amodified. arrangement is shown in which the plunger block 310 is provided with l asleeve-shaped metallic member'31l firmly embedded in the rear face thereof. At the front end of "the shaft I50, as best'seen in'Fig. 19, a

shaft 'portion312 having a decreased diameter is provided so as to fit into the sleeve-shaped metallic member 31 I. Holes 313 areprovided in 0pposite walls of this sleeve-shaped member and a corresponding hole "314 is provided in the shaft portion 312. In order to secure the plunger block 31Ilto the shaft I50, the sleeve-shapedmember 31I is slid on the shaft portion'312 and a pin "315 'is' inserted through the holes 313 and 314, firmly attaching the plunger blockto the shaft. It is evident'that in this arrangement it is very easy to detach the plunger block from the shaft for cleaning purposes'by pulling pin 315 in direction-of arrow316 out-of the holes'3 13 and 314, as best shown in Fig. 19.

A receiver, not shown, for the juice coming out of the outlet opening I I6 during the squeezing operation may be positioned on the portion I4a of base I4. When such receiver isremoved after the squeezing 'operation is completed, there is usually drippings coming out of opening II 6. Accordingly, means is provided for catching such drippings. To this end, a bracket 350 is mounted ona central portion of the curved front wall 24 of the front housing II. The bracket 350 comprises a-w'eb portion 35I and a pair of parallel Thefianges 352 are-formedwith' aligned openings 354. "Received in'the openings 354 arepivotpins 355 extending from either end of a rotatable cylindrical member 356 positioned between the flanges 352. The member 356 is formed witha transverselthrough opening35l. A support member358 is mounted on the member 356. The same comprises a cylindrical rod 359 having one end passing-through the opening 357 in member 356 and an offset portion 36!] extending towards the web portion 35! of bracket 350. The other end of rod 359 terminates in a looped portion 36I which is in a plane 'angularly related to the axis of rod 359. The looped portion 35! is adapted to removably support a cup or other receptacle whose opening is vertically aligned with the opening H6 in the juice box H for receiving the drippings therefrom. It is apparent when the receiver disposed on portion 14a of base I4 is removed, the support 358 is adapted to be swung in a clockwise direction about pivoted member 356 into position relative to the opening H6 to receive drippings from the same. The offset portion 360 of support 358 in abutting web 351 of bracket 350, acts as a positioning means for the support to properly align the receptacle thereon with opening H6.

It is understood that the foregoing arrangement for catching drippings may also be used in conjunction with juice box 26L shown in Figs. 11 to 16 with the cup supported by the member 358, aligned with opening 3 I4 in the juice box.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made, the embodiment above set forth or shown in the accompanying drawing the same is to be interpreted as illustrative and not in a limiting sense.

It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of juice extractors, differing from the types described above.

While we have illustrated and described the invention as embodied in a motor operated continuous orange juicer, we do not intend to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of our invention.

Without further analysis, the foregoing will so fully reveal the gist of our invention that others can by applying current knowledge readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention, and, therefore, such adaptations should and are intended to be comprehended within the meaning and range of equivalence of the following claims.
