SiECI IFIOATION forming part'ot Reissued-Letters Patent No. 12,1 16, dated June 9, 1 903.

Qriglnsl No. '6 11. a,-amd July-9. 1901 Appl To all whom it md'y'concern: j Be it known that I, Dav n Bums, aci'tizen of the United States, residing at-Cam'pc'hase,

in the county of Franklin and State of Ohio,

have invented a certain new and useful Improvement in Corn-Harvesters, of which the following isa specification.

This invention relates to harvesting-ma: chines, and has for its object to provide an improved machine. of 'th-ischaracter wherein the stalks are cut off close to the ground and then delivered rearwa'rdly from the cutting I one partof the delivery within the apparatus to the ground in standing bundles or shocks. It is furthermore designed to have the machine operate simultaneously upon two rows of standing corn and in this connection .to provide for maintaining the stalks cut from one row being delivered from the cutting apparatus. Another object is to prevent choking of upon another part thereof.

A still further object of the invention is to provide for driving the delivery apparatus at different rates of speed, to have the speedcontrolling means in position for convenient manipulation by the driver of the machine,

and also to have said speed-controlling means housed and protected from the cut. stalks when they are being delivered from the cutting apparatus. I

With these and other objects-i-n view the present invention consists in the combination and. arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made scope of the claims without departing from the spirit or sacrificing anyof the advantages of the invention.

In the drawings, Figure 1 is a plan view of acorn-harvesting machine constructed and arranged in accordance with the present invention. Fig. 2 is a similar view, portionsof the frame being omitted to disclose the drive connections between the supporting-wheels oi, the machine and the delivery apparatus.

Fig. l is a detail cross-sectional view taken on the line 4'4'01 Fig. 1. Fig.5 is an enlarged detail sectional view taken on the line 5 5 of Fig. 3. Fig. 6 is a detail sectional view taken on .the' line 6 dotFig. 2. Fig. 7 is a detail sectional view taken on the line 7 7 of Fig. 3. Fig. "8 is a detail perspective view showing the manner of housing the feed-chains. Fig. 9 is a detail sectional view taken on the line 9 9 of Fig. 3. Fig. 7 taken on the line 10 10 of Fig. 9, and Fig. 11 is a detail edge elevation of ou'e'of the ground or supporting wheels "to shape of the main axle.

Like characters of reference designate corresponding drawings.- I

The main frame of the best indicated in Fig. .2 of the drawings, is made up of a pair of substantially parallel, longitudinal, and central or inner'sills or bars 1 and opposite parallel outer side bars or sills 2, these bars beingconn'ected by rear and intermediate cross-bars 3 and 4, respectivel y. Between the cross-bars is a main supporting-axle 5, which is mounted in suitable boxes 6 upon the longitudinal sills and has each end, as shown in Fig. 11, bent upwardly and then outwardly to form an upstanding angular-hanger 7, the. upper and horizontal. member ofwhich forms a spindle for the adjacent ground-wheel 8, and to the outer side of this'ground wheel a sprocket-wheel 9 is rigidly connected thereto for simultaneous Between the forward present machine, as

wheel 10 for the support of the front end of the frame. It will be understood that the axle 5 is depressed or hung below" the spindles in order that the main frame may lie as low as possible to the ground.

For cutting the staudingstalks close to the ground there is provided a cutting apparatus at opposite sides of the center sills 1, consisting of a substantially horizontal table or plat- 'form 11, supported upon the cross-bar l and the adjacent sills l and 2, with its front edge inclined rearwardly and the machine and provided with a rigid cutting blade or knife 12, correspondingly inclined and'adapted to sever the'cornstalks 10 is a sectional view.

parts in all of the figures of the sills 1 there is a castertoward the center of with a drawing or shear-like action when the machine is driven along the rowsof corn.

By referencejto Fig. 3 of the" drawings it will be seen that rear and intermediate stand ards 13 and 14 rise from the outer sills 2 and are connected-at their upper ends by means of the respective longitudinal top sills 15, and to the inner sides of each'of these upstanding supplemental frames is secured a side memberor plate 16, and a front side plate or member 17 extends from the standard 14.to the front of the main frame, with its top edge inclined downwardly and forwardly. It will be understood that there are no supplemental frames rising from the rear portions of the center sills 1; but an inner side member 18, a portion of which is shown in Fig. 7, is supported by the frontportion of each of the center sills 1, preferably upon a supplementalsill 19, carried by the outer sideof the adjacent center sill, as best shown in Fig. 2 of the drawings.

It will be understood that the sides or par-' tit-ions 17 and 18 lie on opposite sides of a row of standing corn, and thereby form a guideway to direct the cornto the cutting apparatus orknives. In this guideway is a' feed device to direct the stalks to the adjacent knifeblade 12, consisting of a pair of endless sprocket-chaius 20, each of w ich works through a longitudinal slot 21, formed in the adjacent partition 17 or 18 and disposed substantially parallel with -the upper inclined edge of the partition and also adjacent to said. upper edge. At the lower end of the slot is an idle sprocket-wheel 22, over which the sprocket-chain runs, and at the upper end of the slot there are two idle sprocketwheels 23 and 24, which are-hung from'the under side of a guard-plate 25, supported upon the upper edge of the adjacent partition and projected at the adjacent outer side of the guideway between the adjacent partitions. Each chain is provided with a series of laterally-directed fingers 26, which project into the guideway and work rearwardly in the direction of-the arrow on Fig. l of the draw-' lugs. To prevent the stalks from beingdrawn into the slots of the partitions, and thereby choking the feed device, each of these slots maybe closed throughout the greater part of its intermediate portion by means of a channel iron' or plate 27, substantially U-shaped in cross-section, with its body portion disposed in the slot and receiving,' the inner side of the adjacent chain and provided at its opposite edges with external longitudinal flanges 28, fastened to the inner side of the adjacent partition. derstood that these channel irons or casings must terminate short of the opposite ends-of I the slotsin order that there may be sufficient openings for the chains to pass through the partitions.

Tho ljeed-chains are driyeig from a main driveshaft 29,which 1s ouruafed transversely across main frame of the machine, and

It will of course be un-' sprocket-wheel 9 upon the adjacent end of the axle 5, consisting of a sprocket-chain 30, running over a sprocket wheel 31, loosely mounted upon the adjacent end of the drive shaft 29, which is projected externally of the frame of the machine. Figs. 9 and 10, it wi-llqbe seen that the sprocketwheel 31 is provided upon its inner side with a reduced hub-like extension 32, that is projected into acup 3.3,rigid upon the drive-shaft. The hub is provided with two or more radial sockets or recesses 34 for the reception of radially-slidable dogs 35, which are normally pressed outwardly by meansof helical springs 36, disposed in the back of the sockets. As clearly shown in Fig. 10,.it will be seen that the outer ends of the dogs are beveled and work in frictional engagement with the cam or eccentric portions 37 of the inner periph-- As best indicated in natingin an abrupt radial shoulder 38, against which the adjacent dog is adapted to engage, and thereby to interlock the sprocket and cup for simultaneous rotation in one direction, thereby to rotatethe drive-shaft 29. The

cam-faces 37 and the shoulders 38 are so disposed as to interlock the sprocket 31 and the cup 33 when the machine is traveling forwardly and to permit loose rotation of the sprocket upon the drive-shaft when the machine is movingrearwardly, thereby to prevent backward operation of the several parts of the machine, particularly when turning at the end of a row.

- For an understanding of the'operative connection between the d rive-shaft and the feedchains 20/ reference is had more particularly to Figs. 3, 5', and 7 of the drawings andalso Fig. 2,-from the latter of which it will be seen that the drive-shaf t is provided with terminal beveled gears 39, adjacent to the outer sides of the maci inc, and similar beveled gears 40 are carried by the drive-shaft and disposed between the longitudinal center sills 1. With each gear 39 there meshes another beveled gear 41, carried by the lower end of an upwardly and forwardlyinclined counter-shaft 2, which is journaled at its lower endin a bracket 43, carried by the main frame, and

journaled at its upper end in a bearing 44, carried by the 'under'sideof the adjacent guard-plate 25. It will here'be noted that the sprocket-wheel 24 (best shown in Fig. 7) is carried by the upper end portion of the shaft-42, and therefore as the adjacent'chain 2O meshes withsaid sprocket the latter forms a drive-sprocket for the former. course be understood that there is a similar drive connection between eachof the beveled gears 40 and the feed-chains which are adjacentthereto, as will be appreciated by reference to Fig. 5 of the drawings.

Below each main feed-chain 20 there is a supplemental shorter iiugeredfeed-chain 45,

It will of disposed parallel withlthe ,upper'chain and working through a longitudinal slot 46 in the ery apparatus, consisting of a series of longitudinal conveyor-chains 48, working over corresponding sprocket-wheels upon the transverse sh afts'49 and 50,mounted uponfthe main frame and disposed, respectively, immediately in rear of the platform 11 and'at the rear extremities of the main longitudinal sills. It will be noted that these conveyor-chains are arranged in two separate and individual sets, one for each knife-blade, and disposed at opposite sides of the longitudinal center of the machinethat is to say, between each center sill 1 and the adjacent outer sill 2-- whereby there ,is a longitudinal interspace. between the individual delivery devices.

Motion is transmitted from the drive-shaft 29 to the rear shaft of the delivery apparatus by two different vconnections, one of which consists of anendless sprocket-chain 51, which is located in the interspace between the two delivery devices and runs overa sprocket-wheel 52 upon the shaft 50 and also over the sprocket-wheel 53 upon the driveshaft, the intermediate portion of the chain being crossed, so as to run the upper mem: bers of the delivery-chains in a rearward di+ rection. The other connection between thedrive-s'haft and the delivery apparatus consists of a gear or pinion 54,1oosc upon the shaft 29 and between the center sills, said gear being in mesh with a larger gear 55, carried by a counter-shaft 56, journaled upon the sills 1 andinrearofthedrive-shaft. Uponthecoum .ter-shaft 56 isa sprocket-wheel 57, over which runs an endless sprocket-chain 58, not crossed, which also engages a sprocket-wheel 59 upon the shaft 50. It will of course be understood that only one of these drive connections is operative at a time, and therefore the sprocket 53 and the pinion 54 are mounted to rotate loosely upon the drive-shaft 29 and may be interlocked with said shaft for simultaneous rotation therewith by means of a tubular clutch member 00, slidablyembracing the' drive-shaft, but keyed or otherwise connected thereto for simultaneous rotation therewith. This clutch member is mounted between the sprocket 53 and gear 54 and is provided at opposite ends with ratchet-teeth for alternate engagement with the clutch-hubs 61 and 62, respectively, of the sprocket and the gear, whereby either of these members may be interlocked withthe drive-shaft to-render one connection between the drive-shaft and the' delivery apparatus active and the other inactive. By having the gear 55 larger than the gear 5 L it will be understood that the connection including these members is arranged to drive the delivery apparatus at a lessrate of speed than the other drive connection,

horizontal lever 63, f ul'cru med intermediately upon across-bar 64, extendingbetween' the sills 1, the front end portion of the lever be}.

ing extended infront of the shaft 49 and working across a platform 65, carried by the center sills 1 and forming a support for the driver or other operator, who will therefore,

bein position for conveniently manipulating the lever to shift the clutchmei nb r60, and

he deliver thereby to change the speed of s best indicated in'Figs. 1 and'4 of the drawings, it will be seen that there is an inverted substantially V-shaped hood or casing 66, supported upon the center sills 1 and extending from the rear ends thereof to or, if desired, slightly in advance of the front end of the delivery device, whereby said hood arches over or bridges the interspace between '11]: status from onerate'to another.

the individual delivery devices, and" hence separates the stalks of the one delivery de-- vice from those of the other and also protects 'the speed-regulating apparatusfrom being choked or interfered with by the stalks. This is a very important feature of. the present invention, as it efiectually preventsv interference of the stalks with the speed-regulating mechanismand also preventsone delivery device from interfering with;the other.

Furthermore, by having'the' delivery devices arranged in parallelism and communicating, respectively, with individual knives and with the hood or casing 66, extended to or in advance of the front ends of the delivery'devices, there is no possibility of the stalks at I one side of the machine interfering with the stalks or any ofthe mechanism at the opposite side of the machine, whereby the latter may effectually operate simultaneously upon two rows of'standing stalks.

For convenience in tying the shocks or bundles upon the machine there is provided a cord-ball 67, (shown in Figs. 1 and 3,) and mounted upon a support consisting of 'a pin or, spindle 68, rising from the'top of one of the outer guard-plates 25, which is extended in rear of the counter-shaft 42 and is disposed horizontally. In rear oftlie cord-ball is a pair of upstandingguide-rolls 69, rising from the guard-plates and between which the cord is adapted to pass. The free por tion of the cord extends transversely across the machine and hasits free terminal held in a clamping device consisting of a roller 70', rising-from the adjacentvgUard-plate 25, and a swinging roller 71, mounted u on the free rear end. of a horizontally-swing ng arm or link 72, which has its forward end pivoted to the guard-plate, as at 73, nal alinement with the roller 70 and at the on ter side thereof.

. In the operation of the machine the latter out of longitud-i-' is driven forwardly to receive a row of standing stalks between each pair of feed-chains.

20, whereby the latter direct the stalks to the knives, which sever the same close to the ground and in view of the fact that the feedchains overlap the front ends of the delivery devices the cut stalks are carried to the de-- livery devices ina positive and effective manner. As the cut stalks are carried rearwardly by the delivery devices they are crowded against the cord, whereby the free end of the latter is-sr ugly clamped between the rollers 70 and 71 and the intermediate portion of the cord is fed /fro'm the ball. When a sufficient quantity of stalks have been accumulated upon the delivery devices, themachine is stopped, the free end of the cord is drawn outwardly,so as to obtain a sufficient amount of cord to tie the stalks into a bundle or shock, after which the cord is cut and the,

machine is started ahead. Normally the clutch member is in engagement with the gear 54, so as to deliver the cut stalks at a comparatively slow rate of speed from the knives, and thereby to prevent the stalks from being-immediately discharged to the ground. When a bundle has been tied and the machine again started ahead, the driver or operator standing on the platform manipulates the lever 63 to shift the clutch from the gear 54 to the sprocket 53, whereby the speed of the delivery apparatus will be. increased and the bundle willbe quickly discharged from the machine, after which the clutch is again shifted back into engagement with the gear 54; From this descriptionit will be understood that the delivery apparatus is normally run at its lowest rate of speed, and the speed thereof is increased only when it is desired to quickly discharge a bundle which has been tied.
