' DIvIsIoN A.

To all whom it may concern Be it known that I, HENRY E. PRIDMORE, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Harvesters, of which the following is a specification.

The invention relates to that type of harvesters commonly termed onc-wheelthat is, having at the inner or stubble end a main or driving wheel and at the opposite or outer end i a grain-wheel or caster, with a platform, usually segmental, but sometimes rectangular, supported between the two, and a sweep or other. rake to clear the gavels therefrom; and it consists in improved means'for raising and lowering said platform; in improved means for tipping said platform upon its supporting or carrying wheels to change the angle of the knives to the-standing grain or to pick up lodged grain; in suspending said platform at its inner end from a supporting-bar pivoted to the drafttongue, and raising and lowering said bar by means of a link from a lever pivoted to a bracket sleeved upon the main axle and connected with the prime-pinion shaft; in suspending the inner end of said platform from a supporting-bar pivoted to the draft-tongue, and making the front connection with said bar by means of a link from a lever pivoted thereon latching into a segment, wh ereby the front of the platform may beraised and lowered toward and from said bar to tip it relatively to its carrying-wheels; in the combination of a main or driving wheel, a main axle, a bracket sleeved thereon and connected by a rearwardly-extending radius-arm with the prime-pinion shaft j onrnaled in brackets from the platform, a cranked shaft running longitudinally beneath the platform and bearing in the arm at its outer end the grain-wheel and link connected from the arm at its inner end to the main axle, a supporting-bar pivoted at its front end to the draft-tongue and at its rear end sliding in a keeper at the rear of the platform, a lever pivoted to a front extension-of the bracket upon the main axle, a rack upon said extension, into which a dog from the lever takes to :hold it in its adjusted position, a link or other connection between an arm of said lever and the supporting-bar, a second lever pivoted to the main wheel in section.

a bracket upon said supportingbar and latching into a rack in said bracket, and a link or other connection between the liftingvarm of this lever and the front of the platform, whereby the platform may be raised and lowered or tipped at will; in the combination of a main or driving wheel, a platform; a grain-wheel at the outer end of said platform, supported upon an arm from a cranked shaft running longitudinally therebcneath, a link connecting a second arm from said cranked shaft at its inner end with the main axle, a draft-tongue hinged to the front of the platform, a bracket for-the seat-standard and foot-rest sleeved to the outer end of the main axle, an arm rigid with said bracket taking at its front end into a keeper upon the draft-tongue, a supportingbar pivoted at its front end to the draft-tongue and at its rear end sliding in a keeperat the rear of the platform, a bracket mounted upon the main axle inside the wheel, connected by means of a rearwardly-extending radius-arm with the prime-pinion shaft, and by a second forwardly-extending arm affording a pivot and rack for a lever linked with the supportingbar, and a second lever pivoted upon said supporting-bar, latching into a rack therefrom, and connected with the front of the platform; in the combination of a main wheel, an axle keyed thereto and turning therewith, a bracket sleeved upon said axle inside of the main wheel, and connected by a rearwardly-extending radiusarm with the prime-pinion shaftmounted in bearings upon the platform, a main gearwheel upon said axle inside of the bracket, and a clutch or backing-ratchet between said wheel and the axle; and in the various other combinations and details of construction here= inafter set forth. 7

In the drawings, Figure 1 isatop plan view of a harvester embodying my invention, with Fig. 2 is a front elevation thereof. Fig. 3 is a side elevation from the grain end, with the platform in section and the vertical adjustment of the latter indicated in dotted lines. Fig. 4 is a like side elevation to illustrate the tipping adjustment; Figs. 5 and 6, details of the clutch between the main axle and the main gear-wheel with the dog engaged; and Figs. 7 and 8 are details quired by the action of the raking mechanism or by the nature of the harvester. To the front of this platform is hinged the rear end of the draft-tongue 0, connected also by a hound, c, with the inside shoe or divider. Pivoted to this draft-tongue, either by the same bolt securing the front end of the hound or at another suitable point, is a strong bar, D, hereinafter called the supporting-bar" or framebar, which runs back to the rear inner corner of the platform, or thereabout, and is there confined by a keeper, d, in which it is allowed to play longitudinally; and, to compensate for the tipping of the platform, it has its under surface at this end beveled. Another bar or braee,'E, rigid with the seat-support and foot rest E, sleeved to the stubble end of the axle, is brought to the. tongue at the pivotal point of the frame-bar, and is there confined with capacity of longitudinal play in a keeper, c, also preferably secured by the pivot-bolt of the hound, and having a pendulum movement, so. as to support the seat in its proper position during the vertical and tipping adjustments of the platform.

A bracket-casting, F, is sleeved to the axle inside the main wheel, and provided witha rearwardly-extending arm, f, secured to the prime-pinion shaft f, supported in standards f at the rear inner corner of the platform, above or adjacent to the keeper for the framebar, said arm thus serving as a radius-bar to keep the prime pinion f in mesh with the main gear G, mounted upon the axle outside of the bracket-casting. In front of the axle the casting F is vertically flattened and enlarged to form a segment'rack, h, with its teeth preferably set ratchetwise for the raising, lowering, and supporting lever H, which lever is pivoted to the casting at h, eoncentrio with said rack, and, by means of a link, h", depending from its crank-arm or ofi'set h, is connected with the frame-bar D at a point over the front part of the platform, thus serving to support said frame-bar from the axle, and through it the rear end of the platform. A second lever, I, is pivoted to a segmentcasting, z, bolted to the frame-bar a little to the rear of the tongue-joint, and, by means of a link, i, connecting its arm '5 with said joint or with the platform, serves to raise and lower the front of the platform or to hold it in fixed relation to the frame-bar. Both levers are provided with hand pieces and links controlling latches which take into the racks upon their respective segments and hold them in any given adjustment. It will be understood that, instead of these link-connections between the lever-arms and the bodies which they sup port, chains or other suitable instrumenialities may be employed. preferable in this, that they holdsaid bodies rigidly to their work and prevent wabbling or jumping.

J ournaled in hangers beneath the platform is a shaft, K, parallel with the fin'genbar, but set sufficiently back therefrom according to the depth of the platform to serve its purpose. At the grain end this shaft has a crank or arm, is, forming a support for the grain-wheel k or caster, and at its inner end, near the main wheel, another arm, k at a slight angle to the former, for more effectiveleverage, but extending in the same directionthat is, forwardand directly connected by a link, k with the main axle, said link being sleeved to the axle so as to swing thereabout, the second arm, however, being somewhat shorter than the grain-wheel support, so that as the platform is raised and lowered in reference to the-axis of the main wheel the relative movement of the grain-wheel controlled by the link from said axis shall keep pace with that of the main wheel, and the grain end of the platform rise and fall parallel with the stubble end.

N ow, supposing the tipping-lever I to be set at any given adjustment, the front end of the platform will be held in fixed relation to the frame-barimmediately above, and if the raising and lowering lever H is manipulated in the appropriate direction this frame-bar will lift the platform concurrently in front and rear, preserving its fore and aft parallelism. Meanwhile, as the main wheel must relatively sink, it will operate the rock-shaft through itslinkconnection with the inner arm thereof, and

The links, however, are.

will move the grain-wheel down a corresponding distance, so as to preserve the endwise parallelism of the platform to its original position; but, supposing that it is desired to tip IIO the platform upon a given vertical adjustment,

the raising and lowering lever HQwill remain untouched, supporting the frame-bar, the rear of the platform, and the tipping-lever I at their fixed height, and the latter lever will be of the platform or to lower it, as may be desired. Either of these adjusting movements will cause a flexion of the draft-tongue upon its pivots, which will be compensated for by the play of the frame-bar in its keeper, and

as to the seat by the play of the arm therefrom pivoted to the platform or abracket therefrom 'movedupon its pivot, so as to raise the front at the rear end, and playin akeeper on the drafttongue at the front end. Therefore, whenever it is qualified in the claims hereinafter as secured in the former way, it is to be understood that the latter is included as an equivalent. It is also evident that the bevel on the rear end of the frame-bar can beomitted and some other compensatory device adopted,as a slot in the platform or a raised keeper having rollers between which the bar plays.

The main gear may be fixed to the main wheel, as in many harvesters now in use, in which case the latter wheel may run loose upon the axle; but, as already stated, I prefer that the main wheel shall be keyed fast to said axle, and mount the main gear G loosely on the axle, connect-ingit therewith by a backing-ratchet, L, so that it shall be driven in one direction only. In order to permit this backing-ratchet to be thrown entirely out of action for transporting the machine, it is con structed as shown in Figs. 5 and 6-that is, a disk, M, is pinned to the axle on the inner side of the gear-wheel, completely closing the ratchet-chamber g therein, so as to shield the mechanism within it. Erom the hub of this disk, within'th'e chamber, is an offset, m, having a cylindriform recess, m, with an opening to one side. Within this recess is set the cylindrical headn of the dog N, having its tongue passing through and playing within the lateral opening. The head is socketed to receive the coil of a spring, a, one, end of which bears against the hub and the other against the tongue of the dog to force it into engagement with the teeth of the ratchet 9'. Near the point of the dog a slot, m is cut through the coveringdisk on an arc concentric with the axis of the dog. A cam-button, O, is placed exteriorly to the disk, with its spindle 0 entering through the slot to a pivotal seat in the end of the-dog, and its cam or latch 0 resting upon the face of said disk. WVhen the dog is in engagement, the spindle of the button will be at one end of the slot. In order to disengage it, the button is pressed backward toward the other end, and then turned until its cam or latch enters into a recess, 0", of suitable shape,formed within a web or rib, m, on the face of the covering-disl ,where it will be kept by the pressure of the spring until intentionally released by turning the button,when the dog will be again forced into engagement. The specific features of this clutch, apart from the combinations into which it may enter with other operative mechanism in a harvester, are made the subjectmatter of Letters Patent No. 272,152, granted on the 13th day of February, 1883, to the McCormick Harvesting Machine Company as my assignee.

Upon the outer face of the gear-wheel are lugs 19, to which is bolted the swiveling member" or gimbal of a telescoping tumbling-shaft P, driving the rake located at the inner front corner of the platform. The prime pinion shaft, mounted, as above mentioned, in bearings on the rear of the platform, with its pinion meshing with said gear and kept in engagement therewith by the radius-arm of the bracket-casting on the main axle, carries, immediately beyond the pinion and integral with it, a beveled gear-wheel, r,which drives a beveled pinion, 1', fast to the end of the crankshaft R, running transversely along the inner end of the platform and beneath the tumbling-shaft, until its wrist-pin is brought in proper relationto the heel of the cutter-bar. Thus the main gear, driven immediately from the main axle in the forward movement of the machine, drives the rake by direct tumblingshaft connection, and the cuttercrank-shaft by means of the prime pinion and single set of bevel-gears, and on the other hand, when from any reason thrown out of action with said axle, causes both rake and cutter-bar to stand at rest.

To economize space and bring the platform close to the inner edge of the main wheel,- the latter is made flaring or dishing inwardly, and the bracket, with its radius-arm, suitably bent and formed to coincide with said dish shape, thus enabling the end of the prime-pinion shaft to be set close to or within the IllitlIl-WhGBIIilIl. Y

The main gear is-also dished, and the ears for the attachment of the tumbling-shaft formed upon the dished face close to the axle or supporting-shaft.
