This. invention relates to beet 'harvest/ers, and particularly to the beet topping mechanism thereof.

rlhe general object of the inventionA is to provide an improved means for trimming the tops off of thebeets to thereby clear the way for the topping knife, provide av topping knife, and means for causing the topping knife-to-raise and loweras it rides over the fw beets to thus cut thetops therefrom, andr to .provide means to clearthe loose tops from the front of the beet digging plow.

A further object vin this connection is .to provide av topping knife mounted for vertical movement and an'endlessbelt or equivalent element vhaving .its vflights extending downward andv rearward at an inclination and adapted to ride over the top ofthe beets, knocking thetops down, andguiding the knife so as to enablethepknife to cut olf the tops in a uniform manner. A still further object is t provide means for knocking downtheloose tops sothat they will not follow around said endless element orbelt. f ,f

Another 'object is to provide adevice lof this character havingv twinbelts. or endless elements operatively connected toA the topping knifefor slight independent movement with relation to the knife tothereby perother, making it possible for the endless elements to clear themselves wheny clogged by ldirt or stones. 1 V f the following description. p

Referring to these drawings, 1,0 designates the side bars of the frame. These side bars at their rear endsrcarry the rear axle llup'on which are mounted the rear wheels 12.- The forward end ofthe frame is supported upon an axle `13 carrying the steering wheels 14,' these wheels beingmountedupon steering4 knuckles 15 and being connected for unitary movement and to be guided by means of the steering wheel 16. We donot wish to be -lim- L i ited to any particular meansfor steering this beet digger.v The 'beet digger is designed to be drawnby horses through the mediu'miof Y any suitable tractive'hitch. A seat 117Y is provided forthe'operator just rearwardv of the ,65 steering'wheel. y f v Mounted upon a bracket 1S extendingforward from the front axle 13 is a sleeve 19 and operating through this sleeve is the vertically disposed pin20'of a yoke which sup- 7o ports the beet top cutting wheels 21.4 These wheels are spacedsufliciently apart v-so that they will extend on each side of the row of beets without touchingy the beets themselves and will act to cut the loose tops therefrom. These cutting Lwheels are' urged downward byv a spring 22'extending around thepin20 andbearing downward upon the yoke which supports the wheels. The wheels' may be Y Y j raised upward against the action of the spring mit these belts to lift, independently of each 22 by means of the operating lever 23 oper` ating over the -usual segment '24, the lever beingv p/rovided vwith meansv for engagingthe segment andholding thelever ing-any adjusted position. The levervis disposed, ofcourse, 8 convenient to the driversy seatj sothat he .may havecontrol of th'ese ,top trimming wheels-'or disks 21.vr l

:Mounted in.' brackets 25 extending downward from the beams 10 fis ayoke 26. This 9oyoke ismounted upon aitransverse shaftV 27, .which in turn is mounted in'these brackets,v and the yoke is pivotally mounted 'uponthis 'shaft so that it, maybe raised orlowered. The yoke carries afleverv ,'28` operatin-gover va 9,5- segmentf29 and'engageable with v,thesegment Y forvarious adjustments... Extendingthrough the rear`l endl ofl 'the yoke'is a :shaft 13(7),v and mounted upon this shaft, and rotatingthereloro Y j ,upward and pvotauyvengaged, allev'err '42 'this level OPGIMHg Over' a sean/lentV 43 from each other and supporting the endless belts 32, these belts being disposed side by side and being of any suitable material and of anyk desired construction. As illustrated, thefbelts are formed of Hat links operatively engaged with each other so as to provide al flexible Vendless element. c

Also mounted upon the shaft for oscillation therearoundy are the longitudinally extending` supporting bars. and .34, the bar 34 being longer thanl the bar'33an'd Vat' its rear end being angularly extended, as at 345,. vThe rear ends of the bars 33 and 34 carry bearings 36 within which is disposed the angularly directed shaft 37, Mounted uponl the bars 33 and 34 are the two1 vertical legs l'38' of aV knife supportingy frame, the lowerV endsv of which support the diagonally extendingknife blade 39. This supporting frame 38 is con'- nected bya hook 40 to arod 4l, extending i in the usual mannery so that the rear end of the endless elementsandthe topping knife may rbe'raised or lowere f Supporting therear 'rollers 731iI of the endless elements 32'is a yoke 43 having anA upwardly extending spindle144which extends through the crossvbar of the ltop of the knife supporting frame. This cross barbas sleeves through which pins `44 extend and yokes 43 are urged downward by springs 45 surrounding the sleeve and pins and'ubearing against c Y, the'yokes. YThus, while the rear ends of the endless elements are mounted formoyement with the topping knife support-ing frame 38, each of the endless elements isinolependently movable with relation to the other endless element. v y

-On the shaft 37 arethe approximately ical rollers46 and 47 having awidth ofat least'that of the'corresponding 'endless elements.

The shaft 60 is caused to rotate'by means of a beveled gear wheel y6,3 engaged by a beveled gear wheel 641nounted Vupon the transverse shaft56. Operating rearward of the top cleaner fingers are the beet plows 65, and'mounted'upon the rear end' of the frame bars 10 are the downwardly and rearwardly .extending armsV or brackets 66. `l`hese sup-V port the transverse shafts vrV67 carrying/'a roller or rollers 68 over which a pluralityof belts L l69 pass. These belts extend forward andfover a plurality of'rollersl O mounted upon ashaft l, which shaft is Voperatively"supportedby means of vertically extending 'rods' 72,- 'the se rodsbeing connected to al lever 7 3, which 1n turny operates over a segment rack 74fwhereby Y thefglever may be adjusted and the' forward ends of theconveyor raised or lowered, Y 1^)isposed between the rollers 70r are` a plu# rality of radially pointed orstar-shapedidlsks 75. f These areidisposed between the severalv rollers .705 and' act p to carry the beets -up Yonto the'conveyor belts 69 fand the conveyor beltsY carry the beetsgrea'rward, shaking the, earth off the beets, and discharge the beets rearward ofthemachine; These conveyor belts 69 are ieu imAV

It is obvious, therefore, that as the crank shaft 86 rotates, the fingers 88 will be caused to describe a circular path and will act to move upward and then downward in front of ay beet and then throw the beet upward 'and onto the conveyor. j

The operation of the beet harvester is as follows: The beets are plowed up by the or-y dinary beet plow orplows suitably mounted on the frame or chassis. Before the beets are plowed up, however, the tops are trimmed by the trimming disks 21 so as to cut off as ymuch of the surplus tops as possible. The topping knife then cuts off the tops of the beets', the topping knife beingv raised and lowered by the endless elements 32 which, being downwardly and rearwardly inclined, act to climb ping knife to a proper position to engage the top at its junction with the beet itself. 'Ihe rear end of this caterpillar gauging device, therefore, rides on the tops of the beets, knocking them down, and enabling the knife to cut oflI the tops in a uniform manner. At'

the rear of the caterpillar gauging device are the knock-down rollers 46 and 47 which tend to keep the tops from traveling over and around the caterpillar belts. Beet tops are very large and tend to clog machines vof this character and anything that will pare'them downor get them out of the way is a greatl help to the operation'ofthe machine and to the accurate gaugingfof the topping knife. .'These loose tops are further gottenfout of theway by the four-armed top clearer which is disposed rearward of the knock-down roll*y ers. This wipes or pushesthe loose tops out of the path of the plow so they will not be carried up into the loading conveyor. Y

` It will be seen that the endless belts which act to gauge the topping knife are vertically adjustable at their forward ends by'means of the ground.

the lever 28 which acts to 'raise or lower the yoke 26 and thus raise or lower the shaft sup porting the forward rollers for the endless elements. Thus the inclination of these endlesselements maybe controlled and the forward end raised or lowered to any desired extent. The rear Lend of the endless elements and, of course, the topping knife, maybe raised entirely out of contact and away from It willbe seenr that this device is relatively simple and it has been found to be particularly',v efficient' in n practice, particularly with "rerl ing 'the topping knife.
