BEET-HARVESTER.

SPECIFICATION forming part of Letters Patent No. 757,425, dated April 12. .1905,

Application filed April 9, 1903. Serial No. 151,761. (No model.)

To all whom it may concern.-

Be it'known that we, HERsoHEf. M. HEILIG,

a resident of Tecumseh, in the county of J ohnson, and MERIMAN H. REED, a resident of 5 Bluesprings, in the county of Gage, State of Nebraska, citizens of the United States, have invented anew and Improved Beet-Harvester, of which the following is a full, clear, and exact description. I

. Our invention relates to improvements in beet-harvesters, the same being more especially adapted for service in harvesting sugarbeets, although the machine or parts thereof may be used for other purposes.

The object of this invention is to provide means for removing the tops of beets while they are in the ground. This topping mechanism is equipped with means for automatically adjusting the same to the position of em- 2 bedded beets, some of which project higher above the ground than others, and such automatic adjusting mechanism is eflective in making the cutter devices slice the tops uniformly from all the beets no matter how high they 5 project. With the topping mechanism is associated a device to regulate by hand the posi tion of the cutting devices. The mechanism also includes means for ejecting the cut tops and refuse out of the path of the machine. 3 The active parts of certain devices are prevented from being obstructed by accumulations of vegetable matter. and the devices are arranged to automatically adjust and clear themselves from obstructions, such as clods of earth and stones, lying in'their path.

Further objects and advantages of the invention will appear in the course of the subjoined description, and the novelty will be defined by the annexed claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of a portion of a beet-harvester, illustrating our improved topping mechanism in connection therewith. Fig. 2 is a vertical transverse section through the machine. Fig. 3 is a plan view' of a portion of the machine, illustrating the position of our topping mechanism. Fig. 4 is anenlarged plan view of the topping mechanism,

omitting the related parts of the machine.

Fig. 5 is an enlarged view in side elevation of the topping mechanism. Fig. 6 is a rear elevation of the topping mechanism, and Fig.

7 is a vertical cross-section taken in the plane of the dotted lines 7 7 of Fig. 5.

5 designates a main carrying-frame of the machine, which at its rear portion is equipped with a drive-axle 6, having ground-wheels 7. The front portion of the machine is supported by caster-wheels 8, each mounted on'a stubaxle 9, having pivotal connectionat 10 with the front portion of the frame, and these axles are provided with forwardly-extending arms 11, which are connected by a transverse horizontal bar or rod 12, the latter being pivoted to said arms of theslewing-axles. The axles may be changed, as desired, to any angle relative to the line of draft by meansof. alever 13, which is fulcrumed at 14 to the drafttongue 15. This lever is pivoted'at 16 to the connecting-bar12, and said lever extends in an inclined direction: toward a drivers seat 17, supported in a suitable way on the machineframe. This frame is equipped with a counter-shaft 18, which is operatively connected by sprocket-gearing 19 to the drive-axle 6, and this counter-shaft is adapted to drive the cutting devices and the ejector of the topping mechanism.

The topping mechanism includes suitable gage-wheels 20, which are individually mounted on short stub-axles 21, attached to the side bars 22 of the trailing frame, said trailing frame being hung or pivoted at 23 to a hol v ster 24 on the under side of the main frame 5 at the front' portion thereof. The side bars 22' of this trailing frame are providedwith upstanding arms 25, to which are pivoted the front ends of horizontally-disposed levers 26, said levers being connected to the arms of the trailing frame by bolts 27 Another trailing frame has side bars 28, connected to the bolster 24 to turn on the axes 95 afforded by the bolts 23. This last-mentioned trailing frame is wholly independent of the gage-wheel frame 22, and the side bars 28 are" provided with horizontal lengths 28 and-with upstanding arms 29, said lengths 28 lying below the axles of the gage-wheels 20, while the arms 29 are disposed in rear of and par+ allel to the corresponding arms on the gagewheel frame. These arms 29 of the trailing frame 28 are pivoted by bolts 29 at theirupper ends'to the rear portions of the levers 26. The trailing frame 28 is equipped with a rotary gage adapted to ride upon the protruding upper portion of a beet-plant, and this gage serves to automatically regulate and de-'- termine the position of the top-cutter mechanism with relation to the embedded plant in order that said cutter mechanism may operate uniformly on all the plants irrespective of the extent which they project from the ground. Any suitable construction of this revof this revoluble gage is loosely journaled in the knee formed bythe union of the arms 28 and 29 of the trailing frame 28. The revoluble gage is disposed practically between the. gage-wheels 20 and in rear of the axes there-v of, and this gage is-adapted to be positively driven by suitable gear connections with the counter-shaft 18, as will presently appear.

The cutter mechanism for severing the tops from the embedded beet-plants contemplates the employment of-a pair of cooperative disks 32 33, each disk having a beveled periphery forming a cutter edge and said disks being mounted or assembled for the cutting edges thereof tohave meeting or overlapping engagement, substantially as shown by the drawmus. po gitively rotated in directions toward each other, and said disks are supported or carried to travel quite close to the ground, although the space between the ground and'the disks may be varied automatically by the operation-- of the revoluble gage, or-said space may be determined by manual adjustment effected by devices to be hereinafter described. The cooperating disks 32 33 are securedrigidly to the lower portions of vertical shafts 34, said shafts being suitably journaledjn bearings provided in vertical elongated sleeves 35. These sleeves practically inclose the shafts throughout their length, and said sleeves are attached to an adjustable frame 36, which is shown by Figs. 1 and 5 as being arranged in a downwardly and rearwardly inclined position. The front ends of the frame bars 36 are pivoted by bolts 37 to depending arms 38 on a rock-shaft 39, journaled in the main frame 5, and this rock-shaft is provided with an upstandingfarm 40, to which is piv- These cutting-disks are adapted to be oted the front end of a link 41, said link extending rearwardly toa hand-lever 42,which is fulcrumed on the main frame at a point within convenient reach ofthe driver occupying the seat 17. The adjustable frame 36 is connected shiftably and pivotally to upstanding arms 43by means of bolts 44, and these arms 43 are pivoted at their lower ends by bolts 45 to the levers26, said leversconnecting the arms 25 29of the trailing frames 22 28, one of said trailing frames, 22, being sustained by the gage-wheels 20. 1

The frame 36 ihay be of any suitable char- "acter; but,as shown by the drawings, particularly Figs. 3 and 4, this frame is U-shaped. The cross-bar of said pivoted frame serves as the means for supporting the sleeves 35 of the cutter-shafts 34. If desired, these sleeves may be yieldably mounted on the suspended frame 36 in a suitable way; but I prefer to provide one of the sleeves 35 with lugs 46,which' are fastened rigidly, as at 47, to the cross-bar of said frame 36. (See Fig. 7.) The othersleeve of the cutter-shaft is provided with a .single lug 48,having pivotal connection at 49 to the cross-bar of the suspended frame, as indicated by dotted linesin Fig. 7, and the sleeves 35 are normally'held in their proper positions by means of a coiled coupling-spring 50, the end portions of which are fastened to the respective sleeves, as shown by Figs. 6 and 7. The upper ends of the cuttershafts 34 are provided with bevel gears 51, which have. intermeshing engagement with similar bevel gears 52, which are made fast with a driving-shaft 53, the latter being'journaled in appropriate bearings 54,provided on the suspended frame 36. This shaft 53, is provided at its middle portion with a sprocket-wheel 55, which is engaged by a.

sprocket-chain 56, extending 'rearwardly to a sprocket wheel 57 on the counter-shaft 18, whereby the shaft 53 serves to drive the cutter-shafts and the cutter-disks simultaneously in opposite directions. This cutter-driving shaft is also provided witha sprocket-wheel 58, engaged by a sprocket-chain 59, that leads to a suitable sprocket on the shaft 30 of the revoluble gage, and the gearing for driving this gage should be so proportioned that the peripheral speed of said gage will exceed the,

speed of travel of the machine.

Theframe 36 is also equipped. with short rearwardly-extending arms 59, adapted to support a horizontal arbor or spindle 60, the latter lying parallel to and in rear 'of the cutterI-driving shaft 53. On this spindle is loosely fitted a hanger 61, the same being forked at its upper portion and provided with rings or sleeves 62, said sleeves being fitted loosely on the arbor to turn freely thereon. The hanger 61 depends for a suitable distance below its supporting-arbor, and to .the lower portion of this hangeris fitted a revoluble ejector 63, the latter being in the form of a concavo-convex disk. This disk-shaped ejector isarrangedin an oblique or diagonal position to the line of draft and to the plane of the cooperating cutter-disks 32 33. Said ejector-disk lies at an angle to the line of draft and directly inthe path of the tops which are cutfrom the em bedded beet-plants by the operation of the cooperating disks 32 33. The arbor 6O sustains a strongcoiled spring 64, which is fitted loosely around said arbor, one end of the spring being attached to-the arbor and the other end thereof being connected with the pivoted hanger 61 in away to normally force said hanger and the ejector-disk toward the front portion of the cutter mechanism. The

hanger and the spring cooperate in yieldably presenting the ejector-disk 63 to the upper face of one of the positively-driven cutterdisks 32, and these parts serve to normally hold this ejector-disk.- in frictional engagement with said cutter-disk forthe purpose of drivingthe ejector-disk by said frictional engagement with a positively driven cutter-disk. It will be noted that the cutter-disk 33, its shaft 34, and the pivoted sleeve 35 may yield or give freely in a lateral direction with ref-- erence to the. companionv cutter-disk 32 and the devices associated therewith, whereby the cutter-disks are adapted to open or spread when they meet with an obstruction inthe path thereof. In like manner the swiveled hanger 61 and the ejector-disk63 are free to yield or give in a backward direction should the disk 63 encounter an obstruction, and it will thus be seen that the several operating devices are yieldably supported in a way to prevent injury thereto by obstructing clotsof earth, stone, or thelike. 4 a

In theoperation of the improved machine the elevation of the top-cutter mechanism may be readily determined and changed by the driver manipulating the lever 42. It is evident that a rearward pull on this lever will rock the shaft 39 and raise the arm 38, which imparts an upward movement to the front end of the frame 36, the latter turning on the fulcrum afforded bythe bolts/14:, thus lowering the rear end of the frame 36, the weight of which is borne by the gage-wheels 20, transmitted through the arms 4E3, the levers 26, and the arms 25 of the trailing frame 22-. The

machine is drawn by a team of horses hitched to the draft-pole :15, and as it moves over a row of beet-plants the cooperating cutters 32 33 are positively driven by motion derived from the main axle 6 and transmitted through the sprocket-gearing to the counter-shaft, the shaft 53, and the bevel-gears heretofore described. At the same time the revoluble gage is positively driven by the sprocket-gearing from the cutter-driving shaft 53. When the cutter mechanism operates on beets which project a slight distance 'above the ground, the revoluble gage rides over the beets without changing the position of the cutter -mechanism; but when said gage rides over a beetplant that projects above the ground beyond a certain distance this gage will elevate the rear part of the pivoted trailing, frame 28, thus turning thelevers 26 on the fulcra afforded by the bolts 27 and lifting the arms 43, so as to correspondingly raise the frame 36, whereby the cutter mechanism is bodily raised so that the disks 32 33 will be made to.

operate on an elevated plant in a way to cut the top therefrom similarly to the cutting operation on beet-plants which project above the ground a shorter distance.

Although we have. shown and described our improved beet-top-cutting mechanism in connection with a beet-harvester of a particular type, it will be understood that we reserve the right to use the top-cutting mechanism in connection with other styles of machines and that we may use parts or all of the top-cutting mechanism herein shown and described. 1 I
