Application filed Api-i127, 1887.

To @ZZ whoml iv' may concern:

Be it known that I, GEORGE EsTnnLY, of Vhitewater, in the county of W'alworth and State of Visconsin, have invented certain Improvements in Harvesters,of which the following is a specification.

This invention has reference more particularly to the ordinary class of maehnesin which the grain is delivered from a rectangular platform by elevating-aprons over the main wheel to a binder located at the outer side thereof; and it consists in various improvements in the construction of the main fratrie, composedv mainly of angular wrought metal or steel bars; in the peculiar formation of hinge-joints, permitting the platform to be turned to an upright position when the machine is to be transported; in the peculiar' mannerof attaching the grain- Wheel when the machine is folded as above, and in various other details, which will be hereinafter described;

In the accompanying drawings, Figure l is aperspective view of a harvester and binder having my improvements incorporated therein, the machine being viewed from the rear stubblecoruer and many of the usual parts foreign to the invention being omitted. Fig. 2 is a perspective View of the main-wheel frame and theinner end ofthe platform-frame, thelatter being shown in a folded or upright position, with a supplemental wheel attached thereto, the parts being viewed from the rear stubble corner. Fig. 2 is a cross-section on the line :r r, Fig. 2. Fig. 2" isa vertical section through the frame from front to rear on the line fr' fr' j members of the frame. Figo is aperspective view showing the elevator and seat supports as viewed from the rear. Fig. 7 isa perspective view of the outer or grain end of the platformframe, showing particularly the divider Serial No. 236,343. (No model.) f

and carrier thereon. Fig. 8 is a vertical cross-v section through the front joint connecting the platformframe and wheel-frame on the line of its axis. Fig. 9 is a similar view of the rear joint. Fig. 10 is a top plan view ofthe mechanism for driving the bundle-carrier.

.The wheel-frame of my machine is constructed,'as shown in Fig. 2, of a rectangular form, comprising as its main elements two parallel trusses, A A', extending in fore-and` aft direction and connected at their ends by cross-bars B B'.

The trusses A A', frequently known as side frames,77 consist each of a straight bottom bar, a, of a "E form in cross section, and of an upper bar, b, of an L, form in cross-section. The upper bar is bent upward from its two ends to a point near its middle. Its extreme ends are extended horizontally, seated firmly on top of the bara near the ends of the latter and riveted firmly thereto. The bar a extends a slight distance beyond the bar I) at each end in order to underlie and support the front and rear bars, B B', to which it is firmly riveted or bolted. The bars B B are'of L form in crosssection, as shown in Figs. 2 and 2, The bars a and b are connected at the middle by an upright segmental slotted rack-plate, C, having lateral iianges, which are seated against and bolted or riveted to the bars a and Ii, as shown. These rack-plates, which are designed to receive the axle of the main wheel and its pinions, by which the vertical adjustment of the frame is effected, are of ordinary construction, and, being familiar to every person skilled in the art, need not be further described.

The front and rear bars, B and B', are each of an L form in cross section, their lower flanges being extended inward horizontally, seated on the ends of the bar a and riveted thereto, as shown in the several figures. The bars B B' are extended outward on the stubble side of the machine beyond the outer truss, A', and are riveted and give support to a bar, c, of a T form in cross-section. This bar, extending in a fore-and-aft direction parallel with the outer truss, assists in supporting the bearings d and e of the shaftf. As shown in Fig. 2, these bearings are supported at the inner sideon the lower member, e, of the truss A' and at the outer side on the bar c. Togive ad- IOO ditional support to the bar c, Iemployabrace, g, extending from the middle of the bar to the upperpart ofthetruss A. Theshaftf, through which motion is communicated to the binder and to the cutting apparatus in the ordinary manner, receives motion through a pinion thereon from intermediate gearing of the usual character connected with the main wheel.

In order to'adapt the main-wheel frame for the proper attachment of the platform-frame thereto, the front and rear bars, B B', are extended horizontally on the grain side beyond the truss A a distance of eighteen inches. (more or less,) and strengthened or stiffened by the application of L-shaped bars h h to their upper sides, the bars being riveted tirml y together, as shown in Figs. 3 and 4.

kThe bars h h are applied as shown in Figs. 3 and 4, their horizontal portions being appliedon top of the corresponding faces ofthe bars B B'and their vertical portions extended downward below said bars. y

The platformframe consists of a front sill or finger-bar, D, and a rear sill, E, the two connected at the outer end by a cross-bar, F, riveted firmly thereto, each of the bars D and E being, as shown, of an L form incrossscction. lThisplatform-frame I hinge to the wheelframe in such manner that it may be turnedV upward at the outer end until it assumes an approximately vertical position, as in other machines at present known in the art. I have, howeverdevised an improved construction of the hinge -joints for this purpose, such as plainlyshown in Figs. 3 and 4.

The finger-bar D has riveted iirml y thereto a forward and upward curved plate or shoe, G, Aprovided at the front grainward or outer corner with a forward extending stud orsleeve,

Z, and at thes'tuNbbleward or inner front corner Withaperforated ear, m. To the overhau ging VWend ofthe front bar, B, is riveted a plate, n,

the upper end of which is turned over the vertical tlange ofthe bar to relieve the bolt, hereinafter mentioned, from the strain and giveit iirm support. The horizontal pivotbolt o is passed in a fore-andaft direction through the lower end of this plate n, through the thimble Z, and shoe G of the finger-bar. A vertical bolt, p, passed through the front bar, B, and through the ear m of the shoe, holds the [ingerbar rigidly in its horizontal position when the machine isin action.

To therearsill, E, is bolted firmly a casting, r, having at its upper end a transverse sleeve or eye, s, to receive a pivot-bolt, t, by which it is connected to a plate, u, hooked upon the vertical iiange and riveted firmly to the overhanging end of the rear cross-bar, B', of the wheel-frame, a vertical bolt, H, located stubblew'ard from the pivot-bolt,passing downward through the bar B and through the sill E,and also through an intermediate sleeve or stoppiece, I, serving to hold the rearsill rigidly in position. By removing the front bolt, p, and the rear bolt, H, the front and rear sills are released, permitting the platform-frame to be turned upward around the bolts o and t, the axes of'which coincide.

It is to be noted as a peeuliarity of my joint that the pivots are located above the level of the platform-sill and below the sills of the wheel-frame, instead of being passed directly through and above the sills, as in other machines. This is advantageous in that it permits the sills of the wheelframe to be kept above thc level of the platform-frame and ata greater height than usual from the ground, whereby the machine is the better adapted to pass over obstructions.

In order to stiffer! the wheelframe and give support to the overhanging ends of the bars B B', I extend braces J K inward from the ends of said bars, as shown in Fig. 2. The brace J extends rearward and stubbleward, and is bolted to the lower mem ber,a, of the i nner truss, A,near the rear side. The brace K is carried forward, stubbleward, and upward,and bolted rigidly to the upper member, b, ofthe truss A.

For the purpose of supporting the grain side of the machine when the platform is in the upright position, I propose to apply the grain wheel at or near the heel end of the platform, as has already been done in other machines.

As a substitute for the usual means of supporting and carrying the grain-wheel when the platform is folded, I have devised the arrangement represented in Fig. 2, in which l\[ represents a short detachable axle extending grainward from the i nnerside of the main frame beneath the inner end of the folded platform to the grainwheel L, which is mounted temporarily thereon. The axle is carried at the grain end by the wheel L and at the stubble end bythe main wheelframe,and at an intermediate point in its length itis seated beneath the cross board 'or bar d* at the inner or stubble en'd of the platform. This bar or board may be one of the sheathing-boards on the un der side ofthe platformframe, as usual, or it may be a special bar or board applied for the purpose, the only requirement being that it ifo ICO

tof,

shall be of sufficient strength to ride upon the axle and sustain the weight of the platformframe. The axle M is provided at its inner end withthe plate o, which enters the inner end ofthe slotted rack-plate C ofthe main-wheel frame, bearing on its tlanges or on top of the bar a. A knee brace or plate, w, fixed to the bar or plank d, is connected by a bolt, w?, with the axle M, or otherwise temporarily attached thereto, to retain the axle in place.

The essence of the invention resides in extending the axle temporarily from the grain side of the main-wheel frame beneath the inner end of the folded platform to the grain-wheel. The details of the devices for holding it in position may, of course, be modified within the range of mechanical skill.

It will be observed that the axle,applied as above,may be quickly detached,and that when in position' it gives direct support to the plat- :form-frame and to the inner side of the wheel frame, allowing the machine to be transported with the same facility as an ordinary twowheeled harvester.

In Fig. 2 I have omitted from the platform` framebottom boards and other parts commonly employed in order to expose the wheel to View, the omitted parts having no connection whatever with my invention.

In order to give partial support to the binder to the elevatoreframe, commonly denominated the Aframa and to'support the seat-plank, I erect on top of the wheel-frame metal frames, one at thefront and the other at the rear in the manner which I will now describe. Y i

I erect on the front bar, B, of the wheelframe, as shown in Fig. 5, two parallel upright bars, x :aand through these I pass a pivot, i, supporting a hand-lever, e, the rear end of which stands adjacent to the drivers seat, while the front end is connected in any ordinary manner with the hinged tongue for the purpose of tilting the machine. From the bars fr, midway of their height, IeXtend in opposite directions horizontal bars c'. The grainward one of these bars is supportedby a vertical bar, b, rising from the front of the wheel-frame. From the front bar, B, of' the wheelvframe, near its outer or stubble side, a

bar, c', is extended upward in an inclined position, and its upper end turned sharply inward toward the grain side of the machine and riveted or screwed to the side-board of' the elevator. bars meet each other they are riveted firmly together, thejoint in each case being formed in the peculiar manner illustratcdvin Fig. 5. As shown in this figure, one of' thebars has its vertical fiange removed from the end backward a short distance and the horizontal flange turned downward, as shown at d. In this way the flanges of both bars are caused to overlap or bear against eah other, so that two rivets or series of' rivets, c and f', may be passed through them at right angles to each other, wherebythe parts are held rigidly in the required relation.

Onthe rear end of the wheel'frame I erect an upper frame identical with `thatjust described, except that the vertical bars .fr .fr are omitted. The construction of this rear frame is plainly shown in Fig. 6.

The elevator-frame has, as usual, front and rear boards, g',to support the `journals of the rolls which carry the elevator-aprons. These boards, formed in the usual manner and ar ranged in the usual position, are riveted or bolted firmly to the bars a, b', and c', as shown in the drawings, this arrangement serving to give firm support to the boards, which inturn act to stiffen the framing.

The draft pole or tongue is provided, as usual, at its rear end with ears or with an eyeplate to receive a horizontal pivot. To support this pivot, I provide at the front of the At the point where the several wheel-frame two eyebolts, 7c', the rear ends of which are screwed through the front bar, B, and through astrengtheningmlate, 7a, thereon, as plainly shown in Fig. 5, with nuits applied to their inner ends, as seenvFig. 2. I also secure to the front bar, B, additional eyebolts l', designed to receive the rear ends of' the lateral braces, by which the tongue is steadied, as usual.

In order to insure the delivery of the grain, cornstalks, or other material properly upon the platform of the machine, I combine with the outer divider a conveyer or picker acting lengthwise of the divider, and preferably constructed in the form shown in Fig. 7, in which N represents the usual divider-board and O a chain extending lengthwise of the dividenboard and passing around suitable supporting-pulleys, m, the chain on one side passing through openings and extendingalong the upper or inner surface of the divider-board. The chain is provided with teeth or projections and connected with driving mechanism by which its upper exposed portion is caused to traverse the divider-board from front to rear, so as to act upon the standing stalks and carry the same backward to the cutters and to the platform. As shown in the drawings, a second pulley, a', is secured on the axis ofthe rear pulley, m', and driven by a chain, o', from a sprocket-wheel, p', on a shaft, g. This shaft, extending along the rear end ofthe platformframe, receives motion through beveled gears r' from the shaft which actuates the platformconveycr. In lieu of the above connections any other suitable construction of' gearing which will impart motion to the chain o may be substituted. In order to permit the tension of the chain to be regulated, I mount its supportingpulleys on pivoted arms s, which vare slotted and secured by bolts t', so that their positions may be changed.

The binding-machine may be ofthe Ap pleby or any other approved type. Its lower edge may be supported in any ordinary manner. Its upper edge is provided, as usual, with the longitudinal supporting-pipe w', arranged to slide through plates x, bolted to the bars c', as shown.

In connection with the machine I employ a well-known form of sheafcarrier, consisting of' a horizontal endless apron, P, revolving rearward in a direction the opposite of the direction of travel around rollers supported in a frame connected to the outer side of the wheel-frame. Heretofore it has been custon'r ary to drive the rear roll of this sheaf-carrier by toothed gearing communicating with the gearing of the harvester. In practice it has been found impossible to maintain this gearing in operative condition or f'ree from cutting for any considerable length of time. I. have therefore substituted `the arrangement of parts shown in Fig. 10, in which a2 represents a beveled gear fixed to the rear end of the usual drivingshaft, f, and engaging constant- ILO ly with the gear b2, having on one side a smooth conical hub, c2, revolving loosely around a shaft, d2, connected by a universal joint, e2, to the journal of the rear roll of the sheaf-carrier. A hollow cone, f2, is arranged to slide on the shaft d2, but connected thereto by a spline or its equivalent, so thatit may be moved forward over the driving-hub c2 at will. In order to communicate motion from the latter to the sheaf-carrier roll, this driving-cone is curved circumferentially to receive a stud on a controlling-lever, g2, which is retracted bya spring. h2, and moved forward by a rod or wire, i2, under the control ofthe driver, who isthus enabled to start the apron at will. The clutchcontrolling lever is plainly represented in Fig. 10, but is omitted in Fig. l for the purpose of exposing other parts to view. The conical friction-clutch may be brought gradually into action, so as to start the apron slowly and avoid the excessive strain and shock which results from the use of the usual toothed gearing.
