Be it known that I, RAYMND B. Gil;-

'cniusT, a resident of Newark, in the county and designs, to rovide improved mechanism for operating t e presser-members; .to pro` vide improved mechanismfor tilting the A-lnernber on which the article from which the juice tobe extracted is held, for convenience in placing the article on said member, or to discharge or remove it therefrom; to protide an improved means by which the pulp will, during the pressngoperation be r'ected outwardly from the center of the lemon and inwardly from the outer edge thereof, so that the pulp will be disposed where the juice will be extracted therefrom by the rotation of one of the members with respect to the other, as distinguishedfrom a device in which the pul is directed to the center, wherein such action does notresult: and further to provide a lemon squeezer ofl improved construction.

The invention consists in the several novel features hereinafter set forth'and more particularly defined by claims at the conclusion hereof.

In the drawings: Figure 1 is a side elevai'c-n of a s'qucezer embodying the invention, the co'i'er of the inclosing case or frame being removed, parts being shown inI sectin, and showing the position assumed b thel mechanism when the cup is ldisposed tb rev eive a lemon and the operating-lever is in normal position. Fjg. 2 is a similar View showing the mechanism in the position assumed when ihe'lever has been o eratjed to squeeze a leinon. -Fig. 3 is la sec ion taken on line 3-3 of Fi 1.

in which the operati -mechansrn is mount'- e'd, and a 'cover-section' 12 adapted to fit against the other section, and to inclose the operating mechanism. v

The 4squeezer cbniprises two 'cperating presser-members, one of which is movable to and from the other to permit the lemon to b'e placed into position to be com ressed, and fr the purpose ofybrihging t e members together to press an article therebetween".

ress-niember 13 is clip-shaped and is rotatably mounted in the frame but against ver tical .m'oveitient therein and is secured to the lwer end of a shaft 14 which is' journaled in said frame and is provided with a reduced upper end l15 whlch is journaled in a hardened bearing 16, which is adjustably connected, by a screw-thread 17 to the frame. ortion of the body-section 11 of the franie ie c lindrically 'shaped to contain said shaft. haft 14 is confined against 'longitudinal movement by a shoulder 18 on the shaft which is adapted to abut against the lower end of the hardened hearing 16 which sei-ves as a thrust-bearing during the ressing operation, and a cotter-pin 19, which secures the shaft against downward movement in the frame. By removing said critter-piti, member 13 and shaft 14 may be withdrawn from the case, and this permits said member to be easily cleaned. The other presser-member 20, which co, erates with rotatable member 13 is remova ly held ih a holder 21, so that it can be conveniently re moved whenever it may Abe desirable to cleanse it., said member 20 having a wall 22 having a shoulder 23 at its upper edge, which iadapted to it u on the upper edge tif the older 21 and tiis member is also )rovided witha suitable handle 24 for conenience in manipulating it and a wall Q2 is cut away at the front to permit the expressed article to be discharged or removed.

einher 2U is perforated, as at 20a. to perin'it the juice to' pass therethrough, int-o a conoidal guide 25 which is held in the holder beneath said member and has a bottom-outlet 26 for direc ing theextracted juices into areceptacle he d beneath it by any suitable means or in any suit-able manner, as well understood inthe art. This conoidal guide is removably held in the holder to 'permit its removal 4for cleansing.

The holder is provided with backwardly ext-ending lugs 27 at the upper and lower ends of which are journaled upper guiderollers 28 and lower guide-rollers 2 9, which areV adapted to travel in guide-ways 30 formed in each side of the case, one pair of these rollers being disposed at each side of the lugs and these rollers are mounted on cross-pins 31 secured in the lugs on the holder. The lower portion of each of these guide-ways is curved backwardly as at 30*1 to cause the holder and presser-member held thereby. to be tilted downwardly. so that during the lower portion of the stroke of the operating-mechanism` thel holder and pressmember held therein` will be tilted to discharge the lemon held thereby or to facilitate the insertion oi the lemon and the removal of the lemon-rind, and during the upper part of such stroke it will travel vertically. Resultantly. when the holder is in normal position, as shown in Fig. 1, it will be conveniently disposed to receive a section of a lemon, and during the operation of the holder, it will be raised and brought into proper position for the pressing operation beneath presser-member 13 and. after each pressing operation, the holder will be tilted downwardly sufficiently to cause the squeezed rind to fall ofi' of presser-member 20 or to facilitate its removal. At the lower end of guides 30, abutments 33 are disposed to'arrest the rollers 29 and limit the downward and tilting movement of the holder.

A lever yor handle 36 is provided for operating the squeezer.` This lever is secured to the outer end of a shaft 37 which is journaled in a bearing 38 formed in the bodysection of frame 11. An oblique toothed gear 39 is integrally formed with shaft 38 and is disposed within the case. The oblique teeth of this gear mesh with worm-teeth 40 formed on shaft 14 of presser-member 13 to cause the latter to be rotated 'horizontally when wheel 39 is rotated by the lever, the shaft being secured against horizontal movement by the thrust-bearing 17 and in 19, asy

hereinbefore set -forth. Resultant y, when the lever is operated in either direction, presser-member 13 will be rotated.

A' flexible operating connection is provided betweeu wheel 39, which is operated by the lever l36, and the holder 21, and in the preferred embodiment of the invention, this connection consists of a linkage between the holder 21which vcarries the presser-member 20y which is movable to and from member 13, and the operating-lever 36, so that the member 20 will be operated to and from the rotatable member 13. This linkage consists of a short member 42 which is pivotally connected as at 43, to wheel 39 which moves with the operating leverand at its' other end, as at 44, to, a n er member 45, which 1s plvoted at 31 to ho der 21. When Losaaeo the connection is in its normal position, as

in the curved portion 30 of guide-ways 30, 1

will cause the holder and therein to swing into substantially horizontal position during the initial upward movement the lever and after presser-member 20 has' resser-member been brought into proximity of member 13 i and the initial squeezing has been effected.-

an abutment 4T on wheel 39 will engage the member 42 and cause it to travel in fixed relation with said wheel so that pivot 44 between members 42. 45 will become operative as a slightly eccentric pivotal connection for effectively bringing the presser-members together for the final squeezing. This pivot 44 is at such time disposed a short distance from the axis of shaft37 acting as an eccentric connection o1' a -short radius, so that a very efective and great leverage results during the latter portion of the pressing operation. This mechanism therefore operates as a differential connection consisting of constantly connected parts, and whereby a long eccentric connection is utilized during `that portion of the operating stroke of the lever, when a rapid stroke is desired, anda short eccentric connection and a greatly increased leverage are attained during that. portion of' the pressing operation when the final compression is effected.' Wheel 39 is provided with a step 48 to arrest it when it encounters link 45, as shown in Fig. 2 and serves to arrest the movement of wheel 39 and the operating-lever. It will thus be seen that this connection constituted of linkmembers,operates asa flexible connection bctween wheel and the holder 21 and this connection will be differentially operated V during the operation of the lever to effectively apply the power for a squeezing operation. The holder, being guided vertically, will descend by gravity during the retractionl of the operating lever. l

Presser-member 20, which is brought into operative relation with respect to compresser-member 13 and which is rotated b v the operating lever, is of, conoidal form and its upper face is provided with an inner series of tangentially disposed straight ribs 50 and an outer series of oppositcl)1 disposed tangential ribs 51, a groove beingI formed between the outer ends of the inner series of ribs 50 and the inner ends of the outer series of ribs 51. As a result of thisI formation of ribs on the presser-member 20. the pulp adjacent the outer edge of the rind will be caused to move inwardly a slight distance to or toward groove 52 and the pulp adjacent the center of said member will be raf of' the linkage. During` further operation of ymember 1 3. l

caused, by the rotation of member 13 above the rind vand ribs 50, :to pass ,outwardly Afrom the center, to groovel52, and ,this formation prevents any pulp from passing to the ,center of the member Where itl would ynot loe subjected to ,the rotative action of presser- The =operation o f theiimproved squeener will be as follows: Assuming the parts to be in vthe position showniin Fig. l "and a section of a lemon or article .to be pressed to have been placed on pressermember 20, lever 36 will be rotated forwardly and suoli shift of the lever will rotate wheel 39 and the oblique ,teeth on wheel 39 will cause shaft lll to be rotated continuously. During the initial movement of the operatinglever, connection ft2, 45 will raise holder 2l and the latter will be brought into substantial horizontal position, as rollers 29 move upwardly in the curved portions 30 of guide-ways 3.0 and when said rollers have passed into the straight portion of said guide-ways, the presser-member 20 will be properly positioned to move directly toward the frotating presser-member 13. This initial. movement of member 20 is quiqkly effected .by eccentric-connection 43 until abutment 47 engages the connection member 42, when the initial squeezin; l,r will have been effected, and the ,presser-members will then be in close proximity to each other. Next, the flexible connection 42, 45` will operate differentially. pivot 44 then `operating as a short eccentric-connection to impart a relatively slow and powerful stroke to pmssermember 20 and thus great leverage for the final pressing operation is attained wben desirable. During the pressing operation and vafter the lemon has .been brought into contact with rotating presser-member 13.v

the latter which is lprovided with ribs 13 will. b v reason of its lrotation of ,the lemonrjnd, cause the pulp near the central porlion of the lemon to be directed outwardly 4to groove 52 and the pulp from the outer portion of the lemon to be directed inwardly to said groove. so that the pulp will lbe'subjected not onlv to directl pressure between the members, but to the rotative squeezing action of rotating member 1.3.

-The inventionfthus provides ,a ysimple land cilicient operating1r mechanism for bringing on(` of the pressermembers toward ,the olllpl' and whereby a ditlferentlal leverage is obtained for effecting a quick stroke ,during the initial movement oftlae presser-member and a greater and lmore effective leverage is attained vdarlin: Ithe final squeezing operition. The invention also provides simple and ellicient means for tilt'i rg the pressern'iember on which the articlg to be pressed is placed, so .that it will be .tilted to dis' charge the rind. /Tlie inventipn ,prnvides an improved form of presser-@tambien which ,will cause ,the pulp to be directed outwardly from the center of t e |,mon V.to subject it to the Vrotative Iaction of It e rotating compnessor-ineniber.

In Figs. 6 and 7 there is shown a modified formof the invention, in which the longitudinally movable oressermember and holder are tilted slightly to facilitate pleo ingr a lemon therein, this modification different from ,that already described in that the guides for the rollers lon the holder are cinwcd slightly to .tiltthe holder merely sufficiently to permit a section ofthe lemon to be placed therein and the presser-member 20 Ihas a complete surrounding wall 22? for holding the lemon and rind on the member 20.
