'This invention concerns apparatusfor sectionali'zing or dividing materials into smaller discrete portions by a series ofy cutting operations. The invention is susceptible of embodiment in 4a machine particularly well adapted forrcuttingvegetables, pitted or cored fruits, meats and the like, into slices, strips, cubes and 'flat-squares or rectangles. In the machine hereinafter described the steps of slicing, cuttin'gtheslicesinto strips and cutting the strips into'icubes arey perform-ed in the order recited at successiveistages, and, while certain novel features'obtain inthe respec-l tive physically spaced sections of the machine where the different cutting operations iocca-rf,- there is a decided interdependence offtheseffeatures in adapting the machinelto'successfully per; form the complete series of operations, wherefore a unity or integrated 'whole exists in`v the various machine sections. H

One important object of the invention `is the 20 provision of an' 'improvedl slicing constituent wherein the material to be slicedis propelled centrifugally about aY chamber wall icyclically lacross a wall opening .and against the cutting edge of a rotating disc knife Awhich slices; portions" from "the material :and facilitates their discharge outwardly through the wall opening. Such :an arrange ment is fast in operation sin-ce the material can be fed into thechamb'er' without ypre-arrangement and also in View of the high speed With which the materialis propelled into -the slicing knife. Because ofthe "centrifugalfoceiactingff the material in the slicing chamber, it aiutomatically assumes-affixed position with respect to the chamber wall sothe sliceslwill havepar allel severed faces.' Only casualfa'tte'ntion is ref quired of the machine attendant -tdsee that the articles operated uponAvare-collectively supplied at :the rate of machine capacity, as distinguished from individualI manipulation and setting fof the articles in the machine. Use of the rotating discI knife adapt-s -the machine foi-operating eilci'en't`l ly upon meats, fruits'with toughfibrous cores and vegetables contaiiing-tougffibersor having'- outer .peels or skins, vas' those ofthe onion, thaty tend to simply fold'over'the edge -of' alixed knife and clog themachine or atleast cause some of the material to be mashed upon comingrincontact with the thus sheathed vcutting edge until the knife is cleared.

"another object is the provision in s sectionalizing` cutting machine, of an improved'arrangenient Vwherebyfthe materialV in the'ou-rse of proc? essiiigis eaused te fon-ewa substantienystrelght 'th so the operating speed need not be limited by the necessity of changing the direction of ow for the material. This is accomplished by discharging the sliced material -onto a straight conveyor belt flight placed substantially parallel to the trajectory of the discharged slices and leading directly toa plane cutting block surface flush therewith and comprising an element of an assembly for cutting the slices into strips. The arrangement is also such that the straight course lcontinues from the strip cutting assembly into an'assembly for cutting the strips into shorter pieces. Straight line passage of the material through the machine between the cutting inf strumentality assemblies as well as within the assemblies themselves has been found to materially increase the speed attainable Without iinminence of misoperation and clogging.

Another object isthe provision in a strip-cutting assembly of a bank of disc knives having their cutting edges serrated to improve their cutting eiiiciency and to augment their tendency to pull the material which is to be cut into the assembly, This is an additional factor contribut` .x ing'to the high ope-rating speed of the machine embodiment herein described of the invention.

A further object is the provision of a cutting block surface with narrow grooves for receiving edge portions of the strip-cutting disc knives for cooperating therewith in completely severing the material into separate strips.

A further object is the provision of a new compressing roller structure with axially spaced circumferential ribs cooperable with thel belt 'i flight for compressing and feeding the sliced material into the strip-cutting assembly and said ribs being meshed with the strip-cutting knivesr toreduce the spacing therebetween Wherefore re;-` silient material being operated upon will have less time to recover from its compressed condition incurred between the belt flight and compressing roller before entry between the knives and the cutting block. This feature has special utility when operating upon a matted layer of loose material such las spinach leaves and stalks.. The

invention further contemplated the formation of the preferred embodiment. thereof hereinafter described and shown in the accompanying draw; il'lgswwherein:l .y

Fig. 1 is a plan view of a machine constituting' a preferred embodiment of the invention;

Fig. 2 is a fragmentary perspective view illustrating feed disc, strip cutting and dicing knife Fig. 5 is a fragmentary side elevational view of'` one of the circular slicing knives;

ing s2 centaine. a shaft 33, Figi. which has a pulley 34 fixed to its rear end as shown in Fig. 1.

This pulley drives a belt 35 which is in driving relation with a pulley 36 rotatively fixed to the rear end of the shaft I2, A second pulley, 31, fixed.

tc the shaft 33 is driven by a belt 38 and a pulley 36 which rotates with the .motor armature shaft 4I.

Fig. 6 is a View taken edgewise of the knife j illustrated in Fig. 5 and taken on the line 6 6 in that figure; and

Fig. 7 is a sectional view taken on the line IQ-1` of Fig. 5.

The apparatus is adapted to operate upon large pieces of material such as those designated P, P and P in Fig. 3. These pieces of material may be any cuttable substancev such as fruit or vegetable articles or pieces of meat. Briefly, in

the operation of the apparatus, impeller blades direction of the arrow appearing just above said belt flight.

When using the slicing complement, comprising the casing C and the slicing knife I4, the material, as fruit, vegetables and meat, operated upon is usually of a crushable nature and the feeding roller I 6 will be removed so as not to press against the slices. contemplated for use most generally when the belt flight is loaded with a layer of compressible Roller assembly I6 is f bunchy material such as spinach or other leafy l material with stems and stalks and not necessarily issued from they slicing complement. Therefore, assuming the roller I6 to be absent, the belt night will slide the slices as S' onto the upper surface of a transfer plate I'I` which col operates with a bank of slicing knives I8' for cutting the Yslices into a series of strips ST. vAs

`lese strips ST emerge fromA between the strip cutting knives I8 they are acted upon by knives I9 carried by a rotatable frame 2| which` rotates with a shaft 22. Knives I9 cooperate with a cutting edge 2e of a stripper plate 23 in cuttingv the strips ST into ldice-like cubes CU.

The apparatus is mounted upon a plate 24, which is preferably the top of a bench or table, and receives driving force from an electric motor M suitably secured to said plate. v Also upon the plate 24 is a standard 25 which supportsy the casing C. A portion 25 of the casing wall I3 is hingedly connected at 2l to the remainder of the circular wall and is supported by means not shown in an adjustable manner whereby the distance of the lower or free end 28 of this wall portion radially of the circular wall from the edge of the slicing knife I5 may be selectively determined. A bearing 29 projects axially from the rear wall of the casing to which it is secured. This bearing contains and provides a journal for the shaft I 2. Bearing 29 is connected with the upper end of the standard 25. The standard 25! in addition to supporting the bearing 29 and the casing C also supports a vertical bearing 3l, Figs. 3 and 4, and a horizontal ybearing 32, Fig. 1,

both formed integrally with said casing. Bearf A beveled gear 42 on the front end of the shaft "33 drives a vertical shaft 45, Figs. 1 and 3, throughv a companion lbeveled gear 46. A flanged knife carrying head 48 for the disc knife I4 is secured Vto the lower end of the shaft 45 illustrated in Fig. 3 and a clamping plate 49 together with machine screws as 5I anchor said knife onto the head. In Fig. 3 it can be seen that the slicing knife is arranged substantially tangentially of 'thewall I3 at a transverse edge 52 thereof and is of sulcient diameter to project beyond such wall edge. Adjacently to its edge 52 the wall I3 has'a beveled face 53 which adapts the upper i'lat face of the slicing knife to occupy the position of contiguity with the Wall edge 52.A It will also be observed that the vupper face of the slicing knife I5 continuesy as a plane surface al1 the Way to its circular cutting edge E while the lower fac-.l of this knife is beveled at 547 to lform the cutting edge. This arrangement minimizes any tendenc;7 for the knife to deect and disturb the position of the uncut portions. of j the'articles as P relaA tively to the circular wall I3', while. providing .clearance at the lower edge of lthe knife for the slices as S to ydischarge tangentially onto the ben flight F.

The feeding and compressing roller i6 has an enlarged central portion 52v and reduced end portions 53 and 54 respectively journall'ed in bearing brackets 55 and 56 suitably supported upon the plate 24 at opposite sides of the feed belt I5. A series of circumferential grooves are cut in the enlarged portion of the roller "i to form axially spaced circular ribs 58. Prior to cutting the grooves 5'I in the roller, its surface l 'is formedy with a fluted periphery so that eac'l of the Icircular ribs 58 has a uted peril `whereon there are circumferentially s,J 9:1

apices 59 which improve the traction of t` Vroller with certain kinds of material passed. he l tween the roller and the belt flight F.r Po' x for driving the feeding and compressing rol? mature shaft 4I. rFrom the pulley 6I the pox, istransmitted through a belt 62, a pulle. fixed to one end oi a shaft 64 journaleii, bearing 65 supported on the plate 24. the shaft 64 power is transmitted from 66 andl on to a gear 61 fixed to the sha '"t 22 carries the dicing knife frameV 2l and nalled in the bearing brackets 55 and 56 gear 6'I driving force lis transmitted to g; fixed to a shaft 69 which is also journ the bearing brackets 55 and 56 and wh ries the assembly of the slicing knives front end of the shaft 69 has a gear 1I xed t`;r

to Iand this gear meshes -with and drives a v. gear 'I2 which is fixed to a shaft 'I3 journcl' 1n the brackets 55 and 56 and carryin n i i pulley 'I4 for the feeding belt I5. Tie f 5.x, i portion o f the wide gear I2 meshes n. drives a gear 'I5 carried upon the reduced t meter front end 53 of the roller I6. The just described power trainof gears and shafts causes rotation of the feedingand compressing roller I6 (when this roller is mounted on-the machine),

' the slicing knives I8 and the dicingknife frame face of the transfer plate for receiving lower edge portions of the slicing dises I8 to 'eonperate with these discs in cutting completely through the slices of material fed across'thetransferiplate and between said discs. the discs I8 which are constrained for rotation with the shaft 69 is determined andimaintained-f by collars 18 placed on the shaft 69 .alternately with said discs.

A further expedient employed for improving -the'ability' of the slicing discs lrto cut the strips ofmaterial into slices is the formation of serrated cutting-edges upon-thesediscsas illustrated.v in Figs. 5, 6 and 7; rOne'lside of each disc is provided with a pluralityof radial grooves 14S which intersect the sharpened-cutting edge 8I,-thereby providing vradially projecting sharpened vedge portions -82 -and radially receding sharpened edge portions 83 alternately withfthe portions 82. VThe projecting vand rec'edingfsharpenededge portions e 82"and"83-are ois'et with respect-toene another axially of the discs-asillustrated in-Figs'. 6 and '7 sothat thecuttng-edgefollowsatortuous path circumferentially-about its disc. This constructionV augments thet'endency-for the knives-to draw th'eslicesyin'to` the space between them and the transfer plate, this improved drawing vtendency being particularly useful when the apparatus is operatingupon meat slices.

The stripperv plate 23 lis also -preferably supported between the rbrackets 55 and 56. Parallel grooves extending'y transversely of the stripper plate are cut-in its lower portion to receive the slicing discs Alfand'toi'form Vvstripper fingers 84 which project between said-discs andprevent ,the slices of material from being carried around by and between theV discs.l Lower edges 85 of-thesev stripper fingers guide the strips for causing them to project beyond -the cuttingedge 20 which cooperates with the dicing knives 'I3 on the rotary frameZl. -Y

When the `machine is used for sectionalizing compressible bulky material asA a heteroger'ie'ously arranged mass 'ofispinach' leaves and stalks, thecompressing roller IB will' be assembled as shown and preferably the lcasing rC and the slicing knife I4 will be removed afterloosening their attach# ment tothe bracket25. This also necessitates re-l moval of the driving belts 36 and 38, but the time involved for effecting'such adaptation of the machine is normally insignificant when considering that many tons of material may be treated thereby before changing the adaptation. Assuming the compressing roller to be installed and the casing'C and the slicingknife I4 to be removed or elevated to provide greater clearance therebetween and the belt flight F, the bulky material will be deposited on the belt iiight in a sufficiently thin stream or matted layer to pass between the roller and the belt iiight incident to being compressed into a relatively compact mass. Positive traction of the roller with the material is enhanced by the peripheral apices 59, and 'downward deection of the belt flight beneath the roller is resisted by an idler roller R, Fig. 3. When The" correct spacing of thus compacted, the material is more readily operated on by the strip-cutting knives i8. To minimize partial recovery of the compressed material from its compressed state prior to reaching the strip-cutting knives, these knives and the ribs on the roller I6 are meshed to reduce the distance betweenthese assemblages..Subsequent to the knives .|815cutting; the compressed material into strips, these strips are cut into short pieces by the knife assembly 2l in the above described manner.
