WILLIAM E. KOCH, OF CARROLL, OHIO. CORN-HARVESTING MIACHINE. Application filed March 21, 1921. Serial No. 453,957. To all whom it may concern: Be it known that I, WILLIAM E. KOCH, a citizen of the United States, residin I at Carroll, in the county of Fairfield and tate of Ohio, have invented certain new and use ful Improvements in Corn-Harvesting Machines, of which the following is a specification. ' This invention relates to an improved corn harvesting machine, and has for its primary object to provide a machine of this nature \vhich,when in operation will serve to cut the corn, to collect and convey the severed corn to suitable receptacles and to provide improved facilities for enabling the corn to be readily removed from the receptacles in a bound, upright and in finished shock formation. I In carrying out the invention, use is made of a corn harvester which is formedto include a horizontally traveling conveyor and a pair of angularly and upwardly extending conveyors, the horizontal conveyor being disposed to receive the corn stalks severed by the cutting mechanism of the machine, and the upwardly inclined conveyors being situated to receive the stalks discharged from the horizontal conveyor so that said stalks may be conveyed upwardly and discharged therefrom into any one of a plurality of receptacles, a pivoted bail member being provided at the open rear ends of the receptacle and formed to carry a chain and windless construction which latter operates to permit of the binding of the stalks disposed within the receptacles, the said harvester further including a manually operated crane structure, wh ch 1s adapted to be employed for the purpose of elevating the stalksfrom a horizontal to a vertical position after being bound by said chain, and to enable said stalks to be removed from the receptacles and deposited upon the ground in a finished condition. A further object of. the invention resides in the provision of an adjustable deflector plate which is adapted to cooperate with the elevator conveyors for the purpose of selectively directing the stalks into either of the receptacles. i j Other objects of the invention reside in the provision of an adjustable center part disposed intermediately of said receptacles and extending longitudinally from the lower portions thereof, the said center bars serving to spread or widen the base portions of the shocks produced by the harvester, in order that'when said shocks are finally discharged from the machine the same will be enabled to stand alone or unsupported; in constructing the pivoted bail member so the latter may be swung to assume positions clear of the shocks when the latter are being discharged from the machine; in the provision of a chain and tongue construction in comcharacters of reference denote like and corresponding parts throughout the several views thereof: Figure 1 is a top plan view of'a corn harvester constructed in accordance with the principles of the present invention. Figure 2 is a vertical longitudinal sectional view, taken through the harvester along the plane disclosed'by the line 2-2 of Figure 1; v ' Figure 3 is a detail front elevation disclosing the driving connections for the conveyors and the cutting mechanism, 1 'Figure 4 is an end elevation of the cutte side of the harvester, Figure 5-is a similar view of the shock forming side, 1 Figure 6 is a detail view of the mechanism employed for adjusting the frame of the machine relatively to the axle of the main driving wheel, p Figure 7 is a detail. view disclosing the each side of the wheel 4. drive mechanism for the gathering conveyors, Fi ure S afraginentary perspective view of the shock forming end of the harvester, Fi 'ure 9 is a detail view of the deflector plate utilised in controlling the discharge of stalks into the shock receptacles, Figure 10 is a detail elevation of the mounting for the pivoted bail member, Figure 11 is a sectional view taken along the line 11--11 of Figure 10, Figure 12 is a rear elevationof the shock from the end of the machine and disclosing more particula the position ofa finished shock, thc final shape thereof, and the position of the pivoted bail member when the latter swung to release the shock. Figure 13 is a detail vertical section taken through the cutter mechanism, and ' 'i 1 1 is atop plan view of said sin. I ReferQing more particularly tothe structural details of the corn harvester comprising the preferred form of the present invention,-the numeral 1 designates a horizontally disposed platformor frame, designated generally by the numeral 1, said platform consisting: in this instance of a plurality-of spaced longitudinally extending metallic bars 2, which are rigidly united to produce a solid and substan-' construction by means of transversely extending angle irons 3, the members Bbein; rigidly and se- 'curely connected in the usual manner to produce a staunch and strong construction. The frame is 'portably supported by means of main and side wheels land 5 respectively, the former being suitably mounted for retation intermediatel'y of-the lengthof the platform, and including a relatively broad tread and a suitable axle 6 which projects beyond both sides of thetread of the wheel, the ends of said axle being disposed within slotted bearings 7, extending vertically, in spaced relation, from the platform 1 and'to The bearings 7 are suitably slotted and have certain of the walls thereof provided in this instancewith rack teeth 8, which are adapted to engage wi h pinions 9 provided upon opposite ends of-the axles 6. In the extreme outer portion one of the ends of said axle .is provided with a" worm gear 10, which meshes with a worm 11 provided upon theforw'ard end of 'rearwardly ext-ending movable shaft 12. lllianifestl'y, by rotating the shaft 12 movement will imparted'to the axle 6 through the medium of the gearing 10 and nuitted to rotate freely 11 This movement results in rotating the pinions 9, which thereby operate to raise or lower the platform-1 by engaging with the teethS ofthe'bearings 7. It will of course be appreciated that the wheel 4'. will be peran d loosely 7 about the axle 6, and that the worm gearing will serve to lock and retain the platform in any of its adjusted positions. In order that the frame may be likewise adjusted with respeet to the side wheel 5, the said frame or platform is provided at one end with an upstanding bracket 13, which carries a vertically movable block 14, the latter being In combination with this platform co struction', use is made of improved gathering and conveying mechanism, which is disposed and formed so that as the machine advances over a fie-ld,'rows will be engaged, the stalks severed at a point near or above the ground and deposited upon the conveying mechanism and thence to one side of the machine in order that the of corn stalks same may be collectedin bundle formation ee-complete the final shocks. The gathering mechanism in the present instance, consists of a plurality of forwardly projectingguide plates 17,which extend longitudinally ofthe machine in advanceof the gathering side of the platform 1. The plates 17 are preferably located in pairs and are formed with curved forward ends 18, which are so related as to provide ibetweenthe same guide ways 19 for the reception of the stalks thecurved ends of said plates serving to enlarge the mouth ends of the guidewaysv inorder to direct the corn toward the cutter mechanism, hereinafter to be fully described, and to accommodate the harvester to irregularities in the spacing between adj ac'ent rows of stalks. I At the inner ends of. the guide ways. 19 the cutter mechanism;of the, harvester is l cated. V This cuttermechanism includes a pluralltvof fixed gulde lingers :20 which are adapted to be stationarily secured to the front bar ,2, and, have their upperjsurfaces suitably recessed (to receive atransverselv reciprocable cutter bar 2 1, which is provided with the usual triangular cutting teeth which have serrated edges 22. Bvt-his con struction the stalks forced the guide ways 19 will be pressed into en'- In order to effect the reciprocation of the cutter bar, the hub of the wheel 4c is prolongitudinally of gagement with the fingers20 and thencev I tive movement. vided with a suitable sprocket 23 over which is trained an endless driving chain 24, this chain leading to a sprocket 25 provided upon a short shaft section 26, which is'lo cated and journaled' for rotation contiguous to the rear edge of th'e'machine. The section 26 carries a fixed clutch j aw 27, which is adapted to be engaged with a slidable clutch section 28, the latter being suitably feathered or otherwise secured to one end of a longitudinally extending shaft 29; disposed along the rear marginal edges of the platform 1. The section 28 is provided with the usual manually operated clutch lever 30, whereby driving connection between the 'sec tions 2" and 28 may be controlled in the usual manner. The shaft 29'is provided at one end with a pinion 31, which is disposed to engage with a similar pinion 32 provided upon a shaft 33, whichis suitably journaled for rotation transversely of the platforml the arrangement being such that upon the rotation of the shaft 29 motionwill be imparted to the shaft 33 so as to effect its posi- I The forward end of the shaft 33 is provided with a disk 34 upon which is mounted an eccentrically-located pin 35, and a pitman 36 is connected at one end with the pin and has its opposite end pivotally connected as at 37 with one end of'the cutter bar 21. Manifestly. by this construction the rotation of the shaft 33 will serve to rotate the disk 34 and thence by means of the'pitman 36, reciprocatory motion will be imparted to the cutter bar. The cutter bar is securely supported for reciprocation in connection with the guide fingers 20 and by cooperation with said fingers and by means of its serrated cutting edges, the corn stalks would be positlvely severed. i r 9' In order that the stalks may be positively forced longitudinally of guide ways 19 and into engagement with the cutter mechanism, theplates 17 are provided with superimposed angular frames 38. which asshown in Figures 1 and 4, extend parallel with the guide ways 19 and are angularly and upwardly inclined the rear ends of said frames 38 being disposed a considerable distance above the platform 1. Suitably mounted at the ends of the frames 38 are sprockets 39. around which pass endless chains 40, the said. chains being provided with laterally extending fingers 41, .which are of sufficient length to project a material distance into the guide ways 19, in order that said fingers may engage with the corn stalks-positioned within the guide waysand to advance such stalkspositively into engagement with the cutter mechanism. It will be understood that theframes may be suitably covered so as to enclose the chains, In order totransmit power to the chains 40, the shaft 29 is provided at intervals with pinions 42, which are disposed to mesh with similar gears 43 provided upon the rear ends of a plurality of transversely extending shafts 44, which are mounted for rotation withinthe platform 1. The forward ends. ily governed and likewise that of'the gath- I ering chains. Carried by the platform 1 and disposed immediately adjacent to the inner end of each of the guide ways 19 are pans 47, which are provided with open forward edge 'portions and with rearwardly located upstanding walls 48. After the stalks have'be'en severed by the action of the cutterbar, the stalks are still engaged by the fingers 41 and are carried rearwardly and longitudinally of the pans 47, the arrangement being such that the lower ends of'the stalks will engage with the upstanding walls 48 and will then be tripped so that when, the stalks are released from engagement with the fingers. 41. the same will fallso as to rest horizontally upon a longitudinally movable conveyor 49. This conveyor is arranged for horizontal operation and is shown more particularly in Figure 2; in which it will be noted that the conveyor 49 is of the apron variety and is situated to extend horizontally and longitudinally of said platform, the outer surfaces thereof being provided with slats 50, which operate to engage the stalks and to convey the same in unison with the movement of the conveyor To operate the conveyor certain of the end shafts 44 are provided with rollers fil around which. the conveyor 49 is trained. It will therefore be seen that the rotation of the shafts 44 will effect movement on. the part of the con veyor in the. direction indicated by the arrow. Suitable means may be providedfor taking up the slack in the conveyor 49. i Arising from the platform 1 is a, skeleton apron variety and are provided with slats 55 disposed for engagement with the corn stalks The arrangement of the conveyors 54 with respect to the conveyor 49 is such that material discharged from the conveyor 49 will be delivered between the conveyors 54', and thence jointly engaged by the latter conveyors and moved upwardly and. longitudinallyof the platform, so as to be elevated above the main operating wheel4. To impart motion to the conveyors 54, the shaft 33 is provided with a suitable sprocket, around which is trained an endless chain 56, as shown in Figure 3, and this chain is also trained around a second sprocket 57 provided upon a shaft 58 upon which one of the rollers 53 is carried. The shaft 58, in turn, is equipped with aspur gear 59, which is disposed to mesh with a similar gear 60; the latter being carried by the roller shaftof the upper elevator conveyor. .By this'con- .struction it will be manifestthat when the shaft. 33 is driven motion will beimparted directly to the lower of. the elevator conveyore, and thence through the gearing 59 and 60 to the upper of said conveyors; so that the elevatorconveyors will becausedto rotate in the direction indicated by the arrows 61' found in Figure 2. This movement on the part of the 'elevator conveyors enables the latter to catch the stalks discharged from the conveyor 49 and to convey the stalks upwardly, as heretofore set forth. At this junction it will be observed that the upper of theelevator conveyors is narrower in respect to width than the lower "conveyor, a construction which enables the conveyors to securelyengage the lower portions of the corn stalks so as to avoiddamage to the ears and foliagecarried by the upper ends of said. stalks. The frame 52 is' provided beneat-h the lower of the elevator conveyors with a wall 62. which has. associated therewith a downwardly curved deck 63, and the upperportions of said frame, above the upper. of the elevator conveyors, is provided with a pair of cross braces 64., v I Carried by one end of the platform 1, be- - neath the discharge ends of the elevator conveyors, isa pair of receptacles 65 and 66, which include bottom, side andfront walls but are open to the rear thereof. as is clearly disclosed in Figure 8, the said receptacles being divided by. means of a partition 67. The receptacles 65 and. 66 do not extend the full width of the platform 1, but terminate shortly thereof to produce a discharging recess 68 to one side of the platform 1, the - said recess serving to facilitate the discharge of the stalks fromthe machine in shock formation. It will be observed that; the dis charge ends .of the elevator conveyors are so positioned that stalks discharged therefrom will normally gravitate into the receptacle 65', but may be directed into the receptacle ees-am 66 by theprovision of an adjustable swinging deflector plate 69, The latter is carried by the upper edgeofthe partition-67 and when the receptacle 65 is being filled, the said plate 69 will assume an upward posi; tion, as shown in Figure 2. However, when thesaid receptacle 65 has been filled to the desired extent, the deflector plate is oscillated to assume substantially the dotted line position, whereby stalks discharged from the elevator conveyors will bedireoted into the outer receptacle. 66 in vorder that the latter may be filled with a suitable quantity. of the stalks. To operatet-he deflector plate, one endof thelatter is provided with a crank 70, with. which a link 71 is connected, thesaid link having its lower end. connected in turn with the crank 72 provided, upon a transback to a positionronti uous to the drivers seat 74 of. the machine, in orderuthatby os cillatinfi the shaft73, the said deflector plate may assume either of itsoperative; positions. The drivers seat 74 is mounted upon aspiring yoke 75, and is situated so that the driver may view the. advance of the machine by looking over the upper of the elevator conveyors. Y Projecting, centrally. the from the under part of the platform 1 is'a versely extending shaft73. This Span ar s pivoted central part 76, ,is situated to normally receive a substantially U [shaped bail member 77. This bail member has one of its arms 8 i-nturned and pivotally inounted within a blocl 79, wh' h ,is slidably mounted upon. a rod 80 carried brackets by a manually operated cr'ank 83 andis. d p e t h e. se h reto bi end o a compressing' chain 84.

In order to discharge the bundled stalks from the harvester, as is of crane 88, which has 1ts ldwer end connected wlth a universal oiiit sate-raise the platform 1. The upper or outer end of the crane 88 is trained a chain 91. is equipped with a pulley 90, around which This chain has its inner end connected with a drum 92 rotatably carried by the crane and adapted to be actuated through the medium of a crank handle 93. The free end of the chain 91 is connected with a pair of tongues 94 used in elevating or arcing the bundled stalks. In operation, after the stalks within the recepta cles 65 and 66 have been compressed by means of the chain 84, the crane 88 is swung so that the tongs 94. thereof may be engaged with the assembled stalks. Then, by operating the drum 92 the chain may be drawn upwardly so as to effect the elevation of the bundled stalks together with vertical swinging movement on the part of the bail member. This upward movement of the stalks serves to draw the latter out of the recep tacles 65 and 66 and by reason of the recess 68, to deposit the stalks on the ground, the center part 76 being so situated, as disclosed in Figure 12, that the lower portions of the shock will be spread or widened, so as to produce a base capable of maintaining the shock in an upright and self supporting position. After this operation has been completed, the shock is bound by twine, and the chain 84 is then released from engagement therewith. The machine may then be moved on by raising the bail member so that the latter will assume the vertical position shown in Figure 12 and will thus clear the upper end of the shock. Since the crane has been previously swung to as sume the position disclosed in Figure 8, it follows that the machine may then advance independently of the finished shock so as to repeat the cycle of operation above set forth. It will be observed'that the bail member 77 is longitudinally adjustable with respect to the rod 80, in order that the same may be adapted to stalks of varying length, the adjusted positions of said bail member being maintained by means of a fixed bar 95, which is provided with notched edges capable of engaging with a tooth or projection provided upon the swinging block In view of the foregoing description, taken in conjunction with the accompanying drawing, it will be apparent that the pres ent invention provides a machine which may be utilized in a practical way for corn harvesting purposes, the machine being designed primarily to efliciently carry out its several functions and yet to be simple in construction and devoid of undue complication. The machine is preferably drawn by draft animals and to this end the frame or platform 1 is provided with a pivoted tongue 96 and with the usual single trees 97 for connection with the harness of the draft animals. If desired, the angularity of the platform 1 and associated parts may be adusted by connectingthe tongue 96 with a pivoted "link 98, which extends upwardly. and has its upper end connected with the short end of a pivoted lever 99, which lever extends transversely of the frame 1 and is pivoted thereon as at 100, the rear end of the lever 99 being provided with the usual latch construction for maintaining the lever in positions of adjustment with respect to a segment 101. Since the tongue 96 is held stationarily by its connections with the draft animals, it will be apparent that by oscillating the lever 99, the said frame may be swung about the pivots provided by the axles 6 and 16 so that the height of operation of the cutting mechanism may be conveniently varied. What is claimed is: 1. In a corn harvester, a portable frame, gathering and conveying mechanism carried by said frame, a receptacle into which material discharged from said gathering mechanism is received, a pivoted bail member cooperating with said receptacle to surround material discharged into the latter means connected to the bail member for compressing the material, and a pivoted crane structure carried by saidframe and capable of elevating the bundled material. 2.
