This invention relates to harvestin machines, particularly to those designed or use in harvesting beans, and'has for its object the provision of a novel device of this char- 3 acter particularly well adapted for use in harvesting soy beans or the like lanted in corn fields and also capable of arvesting beans planted in rows and in fields where there is no rowing corn,-the device being cab pable, in the latter instance, of harvesting two rows simultaneously, 7

An important object of the invention is to provide a machine of this character which will not only" act to harvest the beans, but

13 which will" also thrash them-and winnow them so that when the are discharged from the machine they" wil be in a thoroughly clean condition ready for commercial use.

Another object of the invention is topro- M vide' a; machine of this character which is provided with steering, means and movably mounted win I means cooperating therewith whereby t e operator walking along behind the machine, which may be drawn by any suitable means such as draft animals,

may, by manipulating proper handles-or levers, guide the device in such manner as to harvest and kick out the bean" plants from between hills of corn without injury to the latter. V p

Still another oliject is to provide a device of this character provided withnoyel'means for raising and lowering the harvesting mechanism with respect to the ground traveled over, this adiustment beingfor purposes which may be necessaryas circumstances will dictate.

An additional object is to provide a device of this character in which the power mechanism for operatingvthe thrashing device and winnowin means will be operated by movement oft e ground engagin H wheels over the surface, it being consequent y unnecessary to provide any en 'neror other auxiliary (le- A still'further object is toprovide means whereby the u per portions of the: bean plants'a're bent aterally so asto extend substantiall horizontally within'the machine during t e thrashing operation, thereby makvice for effecting rivingrof any of the partsr ing it unnecessary touti-lize bottom 0 enings for the reception of the plants throng which thrashed beans n t escape.-

An additionalo ject is to provide a device of this character which will be comparatively simple and inexpensive in manufacture, easy to operate and control,-posi ti-ve inaction, elli-v cient and durable in service, and a general im rovement in the art. r, e

ith the above and other objects and advantages in view, the invention consists in the detailsof construction, and the arran 1 went and combination of parts to be herein"- after more fully described and claimed, and illustrated in the accompanying.dra-wi11gs,-in i9 ,e .v

Frame 19 carries a-housing 11- the vfrontof which is formed with a horiza'nltal inlet opening- 11'- which extends to the outer side of the housing and thence rearwarkilyf along at said outer sidein a'substantially horizontal direction, the back portion of; the inlet'opening merge into an upwardlyinclihed enlarged extension of' the opening shdwn at 42; The bottom of the housing is preferably" madein the 'form of-atrough as shown-at 46,, this trough extending rearwardly? and hav'-" ing its rear portion'inclinedmarwardly"and upwardly as shown -at-46;'. It iS tObe understood that frame 10 can carry two housings 10 such as heretofore described, one of them being located at each side of the machine.

engaging wheels 15 and a sprocket 16 loose thereon and adapted to be keyed theretofor rotation therewith by means of a clutch device including a shiftable member 17 engaged by a shifting fork 18 at one end of a pivoted lever-19; which-projects beyond the rear end of the machine.

Mounted at the forward end of the frame IQ-is a suitably mounted vertical shaft or spindle 20 here represented as rigid with the arms of a yoke 21. Loosely mounted in this shaft or spindle isa sleeve 22 forming part of a bracket 23 on the forward end of a. stub tongue or 24. Theshaft or spindle termiiiatesin a yoke 25 within which is mounted'the front wheel 26. Connected with the yoke 21 is a suitable draft device which is here represented as including a support 27 connected "withm tongue, draw bar or the as shown at 24.

like I norally im'licated at 2 8. The wheel 26 0 coursesupports the forward end of the machine -andthis wheelis capable of turned so as to draw the device along in the direction desired. Obviously, if the tongue-or draw bar 28 be moved to one side or the other, the yoke 25 carrying the front wheel will be correspondingly moved.

It is of course desirable that the body 9 containing the mechanism to be described, be vertically adjustable with respect to the surface traveled over, and for this reason I have pivoted the bar 24 to the rear end of the body Secured to the bar is an upstanding member 29 upon which is pivoted at 30, a lever 31 extending to'the rear upper portion of the machine, the rear end carrying a chain 32, a selected link of which may be enn a supporting hook 33 whereby an desired adyusted pos1t1on of the body may be efiected. I Obviously, this will provide means for adjusting the height of the body of the machineitself with respect to the surface traveled over. This is true because lever i as 31 is pivoted to the body at 31", and the forward truck supports the body from point and point 31'.

Journaled transversely of the machine at substantially the central ortion thereof is a shaft 34 carrying a sproc et 35about which is trained a chain 36' peripherally engaging the sprocket 16 on the rear axle of the machine. Journaled transversely of the frame of the machine in advance of the shaft 34 and at .a'lower level are other shafts 37 carrying sprockets 36 about which is trained a chain 38 which peripherally engages a sprocket 39 on the shaft 34. Obviously, when the clutch mechanism is thrown in to lock the sprocket 16 onto the rear axle 14 the shaft 34 will be driven and this will operate to drive the shafts 37. Secured upon each shaft 37 is a pair of supporting members 40 provided at their edges with short lengths of chain 41 which willfact as flails in the manner to be The upper rear ends of the inclined portions 46 of the troughs 46 are adapted to deliver material to the winnowing mechanism designated generally by the numeral 47 located at the rear portion of the machine. Gathering arms 44 are extended forwardly .from the outer sides of the respective housings 11 and each of them has its forward end curved upwardly and laterally as indicated trained about guides 51 located at various spaced points at theforward ortion of the machine, the lower stretch of t e chain passing along over the bottom of the associated or adjacent end member and upwardlyalong the bottom of the associated trough 46. It will be observed that there are two of the chains and that each one carries a plurality of lugs or other equivalent members 52 which will operate to drag the bean vines or branches or portions thereof upwardly and rearwardly along the trough for discharging them' into the shaking and winnowing mechanism to be described in detail. The shaft 48 carries an additional sprocket 53 (Fig. 4) about which is engaged a chain 54 enga 'ng a sprocket 54' to be carried by the sha veyor mechanism defined by the trough and chains 50 will be operated when the machine is drawn along the ground.

Mounted at the rear portion of the machine is a shaker 56 which has a screen bot-v 7 tom 57 This shaker is mounted on hangers 58 suitably connected to the frame, and

34 of Figure 2 whereby the conmovement of the shaker is effected by means I of a lever 59 pivoted at 60 and having one end disposed in the path of movement of an arm 61 on thelshaft 48. At its other end, the V lever is provided with an elongated slot 62 engaging a pin 63 or the like projecting from the shaker. Coil springs 64 are provided which normally act to hold the shaker at one limit of its movement and to return it to normal positions after actuation by engagement of the arm 61 with the lever 59.

Suitably mounted beneath the shaker 56 is a grid member 65 which is formed of a plurality of rods spaced apart a sufficient distance to prevent beans from passing between them while permitting trash and other matter such as fragments of pods and vines to pass through and be discharged. The trash can be removed manually the beans passing 6 to giid65 and passing thence to hopper 66. l ke hopper may of course be constructed in such manner astohave discharge means for permitting the removal of beans accumulat i, therein.

dly mounted at the forward ends of the si es 11,as shown at 67, are outwardly =w'ingable upright boards or side members fisca'n ing wings 69. Side members 68 are adiust al ilc by rods 69'. However, one ele* ment 69 be idle so that adjacent side elements 68,v 9 may be adjusted by handles 7 3, 01' swung to the best position for deflecting the vines toward the machine. Pivotally connected with the side members 68, as shown at 70, is a link 71 which extends toward the center of the machine and which is connected at its inner end with a longitudinally extending bar 72 provided at its rear end with handles 73. Intermediate its ends bar 72 if ivoted to the link 71 so that by grasping t e handles 73 and shifting the bar 72 to one side or the other, the link 71 will be 1 operated to swing the board member 68 and guide wing 69 inwardlyor outwardly as the case may be.

In the operation of the machine the forward end 45 of each arm 44 is adapted to extend along the inner side of a row of bean plants so that said plants will be received in upstanding positions between arm 44 and wing 69. In order that the upper portions of the bean plants may be caused properly to enter the housing 11 the operator swings the wing 69 intermittently so as to bend the plants over the adjacent arm 44 and allow the upper portions thereof to enter the front portion of the opening 11'. Thereafter, as the machine moves forwardly, the upper portions of these plants will remain in substantially. horizontal positions within the housing and within the side portion of opening 11' as will be apparent by referring to Fig. 5 wherein the plant has been indicated at P. Thus the upper portions of the plants, while held in substantially horizontal positions will be beaten by the chains 41 rotating with the member 40 and the pods will be broken open. The beans liberated therefrom will gravitate onto the hopper like bottom 46 and then be carried rearwardly and upwardly by the lugs 52 on chain 50. These lugs will scrape the beans onto the shaker 56 which is moved rapidly back and forth by the action of member 61 on shaft 48, this member engaging against lever 59 which, in turn, is pivotally and slidably connected with the shaker. After the plants have been beaten or thrashed as described, the upper portions thereof will withdraw through the rearwardly and upwardly inclined enlarged portion 42 of opening 11'.

When the device is used for harvesting and thrashing two adjacent rows of beans it is obvious that the board members 68 and wings} 69 should be fastened open to the side of the harvester, the link 71 being disengaged from the member, 68, the elements 71, 72 and 73 being removed. When it is intended to harvest beans such as soy beans, which are commonly planted between the hills of corn in a corn field, the device is driven along between successive rows of corn and from time to time the operator-manipulates the handle W5 7 3 to move the bar 72 assumed to be pivoted at its forward end, and lateral movement of the handle 73 results in opening or closing member 69, for moving into the pathof the machine, the bean vines growing-between hills of corn.

From the foregoingdeseription and astudy of the drawings, it willbe apparent that I have thus provided a comparatively simple and consequently relatively inexpensive machine by means of which-beans of various kinds may be harvested regardless-of w-heth er they are growing. in rows ina-field or whether they are. growing between corn plants in hills in a corn field, means being provided whereby beans growing bet-weelzi hills of corn may be-quiekly and easily gathered in without injury to the corn plants. It will be observed that ample provision has been 'made for-all adjnstment necessary for the proper action and it is' believed that .the constmotion, operation and advantages will bereadily apparen-t'to one skilled-in the art-without further explanation.

While I have-shown and described the {pr ferred embodiment oftheinvention, it'should be understood that I- reserve the right to make such changes in the form, eonstruetion and arrangement of vparts as will'not depart from the spirit of the invention or the seopeof the subjoined claims.
