SPECIFICATION forming part of Letters Patent No. 477,709, dated June 28, 1892.

Application filed June 21, 189 (L To aZZ whom it may concern.-

Be it known that I, JOHN F. STEWARD, of Chicago, in the county of Cook and State of Illinois, have invented certain new and use- :Zul Improvements in IIarvesting-Machines, of which the following is a full description, reference being had to the accompanying drawings, in which Figure 1 is a front elevation of so much of the machine as is necessary to show the parts which are new. Fig. 2 is a rear elevation of the same. Fig. is a stubble-end view of the binder attachment. Fig. 4 is a stubble-end view of the same, showing the parts in a different position of adjustment. Figs. 5 and 6 are details of the reel. Figs. 7 and 8 show the means for supporting the bearing for the crank-shaft and holding the pinion of the crank-shaft and gear which drives it into mesh. Fig. 9 is designed to illustrate the construction of certain parts of the main frame. Fig. 10 shows the construction of the bearing for the reel-driving shaft so that its sprocketwheel may serve as a tightener of the chain which drives the lower elevator and binder attachment.

The object of this invention is to so provide that a machine may be adapted to work upon crops of exceeding length -as, for instance, long rye, corn, sorghum, or other fodder products-as well as short grain, if required; and its nature exists in giving the reel extreme positions of adjustment and also in giving the binder various extreme positions of adjust. ment, in means for; actuating the parts so adapted for extreme adjustment, and in various details of construction, which will be fully pointed out. 1

A is the main supporting-wheel, its axle supported in the usual quadrants, the latter secured to the frame-pieces, preferably of truss fornnas A and A secured to the sills A and A B is the finger-bar; B, the rear sill; E the platform, and 13 the shoe.

In order to brace the frame to keep it from getting out of square and also to brace the trusses and hold them erect,I use the braces O, 0', C and G I do not claim the system of bracing here shown, because that is already secured to me in Patent No. 396,2 i5; but I have improved the construction there shown Serial No. 356,299. (No model.)

by making the brace O a strong bar of iron, securing it at its rear end to the truss, preferably near the axle-quadrants. It may be however, secured to the quadrant or any other suitable portion of the frame-work.

B is a saddle-piece adapted to lie between the sill A and the finger-bar B. I make this also serve as a part to secure the brace O to by means of the bolt 13*. The brace C also takes this bolt. I extend the brace 0 forward of the finger-bar and bolt it firmly to the shoe B by means of the bolt B". Heretofore the weight of the reel and of the upper framework of the machine has restedupon the shoe, and the pressure has had the tendency to tip the said shoe forward and downward, and also, because of variations in manufacture, the shoe has not always been brought to a definite position. Again,the draft of the tongue coming upon the shoe, there has been a tendency to tip it upward, especially when the machine is tilted down. Extending the brace 0 forward and bolting it to the shoe, the latter is always held positively in place.

D is a part of the forward A-frame, to which is attached the slides and guides for the elevating-can vases, the latter forming bearings forthe journals of the elevating-rollers.

D is a support for the forward end of the seat-board, properly secured to the A-frame board.

D is a support for the upper end of the elevator-frames, footed upon the main frame in the usual manner. Secured to the A-frame board is a plate of metal D. To this, as shown in Figs. 5 and 9, the reel is pivoted, the reel-support consisting of the horizontal bar D and the vertical post D suitably braced by D. The bars D and D are secured together at D by a saddle-piece, which also overreaches the hub of one of the reelgears to hold it in place. This bar D is made, preferably, of gas-pipe and is adapted to rock in the su pportsD and D, the latter of which is secured to the post D. Upon this bar, as an axis, the reel is adapted to rock forward and backward. D is a gear on the forward end of the elevating-roller D Having cast as one piece with it, preferably, is a sprocketwheel D. The pinion D is adapted to mesh into the gear D and rotate it on the bar D Preferably east as one piece with the gear D is another gear D which meshes into the pinion D. This pinion rotates on a stud on the bar D and is provided with the shaft D, which extends upward beside the reel-post and is squared where it passes through the pinion D The reel is mounted on a shaft, as usual, and upon the shaft is the gear D", by means of which the reel is given rotation.

E is the reel-bracket, adapted to slide upon the reel-post. To it is pivoted the bifurcated reel-lever E. The said lever is pivoted to the upright lever E, which is adapted to rock backward or forward when unlocked from the quadrant E The means for controlling the reel, as shown in Fig. 6, is not new to this application, being shown, described, and claimed in patent to me, No. 346,232.

The improvement herein claimed consists in the means for varying the height of the reel and also in connecting it with the main driving-gearing. The improvement is best shown in Figs. 1, 5, and 6. In Figs. 1 and 5 the reel-post and driving-shaft D are shown to be of great height, and a special bracket E is shown to be so adapted that the forward end of the reel-lever may be pivotally bolted ,to it, the same as if bolted to the bracket E.

When so pivoted, the bracket E" may be raised or lowered at will. To this I bolt the stiff connection E The bracket E is also provided with lugs, so that it may be securely bolted to the same connecting-piece. By the use of this connection the reelbracketE may be raised to any height desired without changing the action of the reel-lever. In cutting sorghum it is necessary sometimes to raise it to'an additional height of at least four feet, yet in some conditions it is not necessary to raise it so high, and henceI provide holes, so that it may be adjusted to intermediate positions, if desired. By movement of the lever adjustment of the reel is permitted when placed to its high position, as shown in Fig. 5, from the drivers seat. The bracket E is extended grainward from the post to the same extent that the one Eis, and the reel-lever being forked and connected to the upright lever E, which cannot move sidewise, a retary movement of either of the brackets on the reel-post as an axis is not permitted. WVhen the lever is secured to the bracket E and the stiff connection E is used, the bracket E, and hence the reel, is prevented from swinging or rotating backward or forward on the reel-post.

I have mademy machine to have an open end, and for that reason cannot drive the upper elevating-canvas from the rear; nor can I drive the reel from the same position. Hence I provide ashaft E, which passes from rear to front of the machine beneath the elevators and to it secure the smocketwheel E The shaft is adapted to rotate in the bearing E which is supported upon the bar D" and adapted to slide thereon.

E is a threaded hooked brace, passing through the post D and having nuts upon either side thereof, by turning which the bearing E is moved so as to take up any slack in the driving-chain E The gearingin this machine may be of any of the ordinary constructions and the sickledriving mechanism and elevating device the same; but in the latter I make some modifications.

F is the rear A-frame board, adapted to receive the elevator-rollers, over which an elevating-canvas is drawn.

F is the U-shaped support secured to the platform frame-work and extending backward, upward,and forward beneath the seatboard F It may be secured at the edge of the board, or above, if preferred. Secured to the seat-board is the bracket F having the arms F and F slotted at their ends. To these arms is secured the upper elevator frame-piece F. This frame is secured at front to the A-frame board D. In handling very bulky corn it is sometimes desirable to open the rear of the elevator to allow more room for ears and masses of stuff to pass. This adjustment is also desirable in some conditions of grain. Bymeans of slots in F and F the upper elevator may be moved away from the lower one.

G is the crank-shaft, suitably connected to the main wheel by ehain-and-tooth gearing, which need not be described. Upon the sprocket Wheel G is thrown the chain G which passes around the sprocketwheel G on the binder packer-shaft, around the sprocket-whcel G upon the elevator-shaft, around the sprocket-wheel G upon the shaft which moves the platform conveyor, and around the sprocket-wheel G" upon the shaft E. The shaft last mentioned is supported in the bearing G as shown in Fig. 10, adjustable on the post G As either end of the shaft may require adjustment to tighten the chain at front or rear independently, the shaft might when moved at the front end bind in the bearing at its rear end. To prevent this the bolts securing the journal-bearing at its rear end may be slightly loosened, so that the hearing will shift as the shaft is moved, after which the bolts securing said hearing may be tightened. Practically, then, the bearing may be considered as automatically adjusted when set free by loosening the bolts. This wheel thus serves as a tightener for the chain G and also serves to give rotation to the shaft E, which gives movement to the reel and also to the driving-roller of the upper elevator. By the adjustment referred to it is thrown alittle out of line; but the chain is nevertheless found to run perfectly. The chain G is provided with the teeth which project upward slightly into the swath of grain that is being elevated and makes the movement more positive. An eX- tension may be provided which will support the tops of the grain that project to the rear of the elevator and chain.

The binder, as far as its operative parts are ITO concerned, does not differ from others now in use; but means are provided whereby its parts can be adjusted to exceedingly-long grain. These improvements will be understood by reference to Figs. 3 and 4, where H is the binder-frame, having in the upper sleeve thereof the shaft H, which gives motion to the cord-uniting devices and bundle-discharging mechanism. This shaft is rotated bya gear H at its front end and has the knottermoving cam-wheel H keyed thereto. This shaft is made much longer than the arm of the binder in which it is journaled, and to take up such additional lengths the sleeve II is used.

In Fig. 3 the knot-tying devices II are shown as located upon the rear end of this shaft and the sleeve H placed between it and the end of the main binder-frame sleeve. This is the position of adjustment desirable for binding sorghum corn, and other long crops.

In Fig. 4 the knot-tying devices are shown as placed adjacent to the end of the sleeve of the main binder-frame which forms the bearing for the shaft, and the sleeve H is placed at the rear thereof. By unscrewing the nuts from the rear end of the shaft 11 the knotting device and the sleeve II may be quickly transposed.

I1 is the needle-shaft, and H the needle. This needle is keyed to the shaft and is capable of being moved to any position to correspond with the fore-and-aft adjustment of the knotting device.

The compressorl is supported upon the arm I, which in turn is pivoted to the heel of the needle.

I is an arm on the compressor-shaft 1 the said arm being connected to the compressorsupport by the link I". This arm is adjustable along the com pressor-shaft, so that when the needle is moved it can be moved to a position beneath the compressor, in order to operate the same properly. As the binding and compressing device in all other respects con forms strictly to binders now in general use,

I need not describe them further than to say that the clutch-tripping arm J is adj ustably secured upon the long shaft J, and on this shaft it may be slid to conform to the position of the needle.

K is the packer-shaft, provided with the cranks K and K The cranks K are placed well toward the rear of the binder and the cranks K in the position suitable for binding grain. When desirable, each pair of these cranks may be provided with packers, as shown in- Fig. 3, where they are represented by L, L, L and L as of the ordinary construction, suitably linked to supports upon the binder-frame. For convenience I link the packers to supports secured to the shaft L"; but this does not form part of my presentinvention and need not be described as they are suilicient-ly shown in Fig. 3.

M is the binder-table, to which I apply the the bearing P for the crank-shaft.

rearward extension M. In order to control the rear end of the grain, I provide the additional spring-wires N and N, secured to the supplemental rail N I11 Fig. 7 Ishow means whereby the main gear 0 is moved into mesh with the pinion O. 0 is a casting surrounding the axis of the gear 0, and between it and the gearsleeve'is shown a washer 0 The casting O is adjustable by means of the set-screw 0 In order to adjust the height of the pinion 0' relative to. the gear in which it meshes, I provide the bracket P on the sleeve upon which the gear 0 revolves and place loosely in it I? are set-screws, the heads of which rest upon the bars of the truss. B y adjusting these screws the crank-shaft may be moved upward or downward and put into adjustment with the gear which drives it and keeps it there.

I shall claim the construction of the binder whereby it is made to be extensible as distinct from adjustable; also, the reel. In each I provide special means whereby the parts which act upon the grain are adapted to be extended in the direction that long grain requires-as, for instance, in adapting the machine for the cutting of corn and sorghum.

Although the seat and elevator support F passes upward in the rear of the elevator, it is adapted to be placed so far to the rear as to make the machine practically open at its rear, and I shall treat it as a rear-opened machine.

I am aware that it is old to adjust the banduniting mechanism and the needle upon their respective shafts; but I arrange and place the parts so that by mere use of extensionpieces and by transposition of parts the machine is adapted to work upon corn or upon short grain, as the case may be. For the pur pose of moderate adjustment to the length of the grain while the machine is running, the whole binding attachment may be moved, as is done in ordinary machines.

WVhat I clai mas my invention, and desire to secure by Letters Patent, is-

1. The combination of the open-end elevator, the binder havinga supplementary table by which it is made extensible in a rearward direction relative to the main binder-frame and having a rearwardly-extended knotterdriving shaft, by means of which the knottying devices maybe moved rearwardly relative to the main binder-frame, and the long needle shaft whereby the needle may be moved to a rearward position and the binder thus made extensible in a rearward direction, all of said extensions and adjustments in a rearward direction being ma e relative to the main binder-frame, whereby long ci hfl w MWWWJW be handled without adjusting the main bind er-frame rearward, substantially as described.

2. In combination with an open-end elevator, a binder-frame secured to the said harvester-frame and having a long needle-shaft and a longknotter-driving shaft, a needle and a knotting device secured to said shafts and adapted to be moved to a rearward position relative to the main binder-frame, so as to overreach the butts of very long grain, said harvester having a reel adapted to be moved to a high position to overstep long grain, the extensibility of the reel and the extensibility of the needle and the knotting devices in a rearward direction accomplished by interpos- I ing between the reel adjusting devices a lengthening-piece, and lengthening-pieces between the said needle and said knotting devices and the main binder-frame, substantially as described.

3. In a harvester, the combination of a reel having an extension-piece E said extensionpiece rigidly secured to the reel-bracket and to a supplemental bracket secu red to the reellever, whereby the said extension E is by means of the reel-lever prevented from rotating around the reel-post, and the reel-bracket is thus prevented from rotating or swinging around the said post, substantially as described. I

4. A grain harvesting and binding machine adapted to operate upon corn or sorghum and other high crops by means of an extension-piece, whereby the reel may be supported in and be adjustablein ahigherposition than that in which it is held for binding grain and there controlled by an extension-support that shall also prevent the reel-bearing from swinging on the reel-post, an elevator spanning the butts of the stalks, and the self-binder provided with an elongated needle-shaft and an extension-piece that may be placed between the needle and the main binder-frame, andan elongated knotter-driving shaft having an extension-piece that may be placed between the main binder-frame and thesaid knotting devices and hold the latter in position, substantially as described.

5. In a binding attachment, the combination, with the main frame, of the shaft H, the band-uniting devices mounted thereon, and the sleeve H the said sleeve and knotting device transposable in their positions, in combination with band-placing mechanism adapted to be moved on its support to a proper position relative to the said band-uniting mechanism, substantially as described. v
