lSPECIFICACIIN forming' part of Letters Patent No. 270,120, dated January 2, 1.883.

Application filed Septembcrlg, 1882. (No model.)

To all whom .tt 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 use'- ful Improvements in Harvesters, of which the following is a specification.

The invention relates to that type of harvesters commonly termed one wheel7-that is, having at vthe inner or stubble end a main or driving wheel and at theopposite or outer end a grain wheelor caster, with a platform usually segmental, but sometimes rectangular, snpported .betweenvthe 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 supportingor 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-barpivoted to the draftiongue, and raising and lowering said bar by means ofa lilik from a leverpivoted to a bracket sleeved upon the main axle and connected with the prime `pinion-shaft; in suspending the iii-1 ner end of said platform from a supportinghar pivoted to the drafttongue, and making the front connection with said bar by means of a link from a lever pivoted thereonlatching into a segment, whereby the front of the platform may be raised and lowered toward and from said bar to tip it relatively to its carry- Aing-wheels; in mounting the rear of the platform upon a rock-shaft-runninglongitudinallyy therebeneath, and provided at its outer end with a forwardlyextending arm, in which is pivoted the grain-wheel, and at its inner end 3 with a like arm parallel ornearly parallel with the first, connected by means of a link with the main axle or a sleeve thereon, so that as the inner end of the platform is raised or lowered the outer end shall move simultaneously therewith and preserve its parallelism; in the combination of a main or driving wheel, a main axle, a bracket sleeved thereon and connected by a rearwardly -extendiug radius arm with the prime pinion-shaft journaled 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'conn'ectedfrom the arm at its-inner end tothe main axle, a supporting-bar pivoted at its front end to the draft-tongue and at its rear end sliding in a keeper at thev rear of the l 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 a bracket upon said supporting-bar and latching into the rack in' said bracket, and alink or other connection between the arm of this lever and the front of the platform, whereby the platform may be raised and lowered or tipped at will; in the combination end to the draft-tongue and at its rear end sliding in a keeper at the rear of the platform, a bracket mounted upon the main axle inside the wheel, connected by means ofa rearwardlyexteuding radius-arm with prime pinionlshaft and by a-second forwardly-extending arm, affordin g a Apivot and rack for a lever linked with the supporting-bar, and asecond 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 rearwardlyextending radius-arm with the prime pinionshaft mounted in bearings upouthe platform, a main gear-wheel upon said axle inside of the bracket, and a clutch or lbacking-ratchet between said wheel and the axle, and in the various other combinations and details of construction hereinafter set forth. A

In the drawings, Figure lis a top plan view IOO - the' rear end of the platform.

of a harvester embodying my invention, with the main wheel in section. Fig. 2 is a front elevation thereof. Fig.3 is a side elevation from the grain end, with the platform in section and the horizontal 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 of such clutch with the dog out of cngagement.

A is the-main wheel, for the purpose of the present gearing keyed fastv to its axle a, but, if demanded by the nature ofother gearing substituted therefor in the machine, allowed to turn loosely on said axle.

B is the platform, .of any suitable shape required 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 C, connected, also, by a hound, c, with the inside shoe or divider.

Pivoted to this draft-tongue, eitherby the same bolt securing the front end of the hound or at another suitable point, is a strong bar, l), hereinafter called the supporting-bar or frame-bar,77 which runs back to the rear inner corner of the platform or thereabouts, and is there confined by a keeper, d, in whichit-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 brace, 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 piv- -otal point of the frame-bar, and is there conned with capacity of longitudinal play in a keeper, e, also preferably secured by the pivotbolt 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 theaxle inside the main Wheel and provided 'with a rearwardly-extending arm, f, sleeved to the prime pinion-shaft f', supported in standards f2 at the rear inner corner of the platform above or adjacent tothe keeper for the framebar, said arm thus serving as a radius-.bar to keep the prime pinion f3 in mesh with'the main gear Gr, mounted upon the-axle outside of the bracket-casting. ln front of the axle the casting is vertically Hatten ed and enlarged to form a segment-rack, h, with its teeth preferably set ratchet-wise for the raising, lowering, and supporting lever H, which lever is pivoted to the casting ath', concentric with said rack, and by means of a link, h2, depending from its'crank-arm oroifset h3, is connected with the frame-bar at a point over the front part of the. platform, thus serving to support said frame-bar from the axle, and through it A second lever, l, is pivoted to a segment-casting, t', bolted to the frame-bar a little to the rear of the tongue-joint, and by means of a link, i', connecting its arm t2 with said joint or with the platform, serves to raise and lower the front of' the platform or to holdit in xed relation to 7o the frame-bar. Both levers are provided with hand-piecesandlinks controllinglatches,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 support, chains or other suitable instrumentalities may he employed. The links, however, are preferable in this that they hold said bodies rigidly to their work and 8o prevent wabbling or jumping.

Journaled in hangers beneath the platformis a shaft, K, parallel with the linger-bar, but

set sufficiently back therefrom, according to the depth ofthe platform, to serve its purpose. At the grain end this shaft has a crank or arm', lo, forming a support for the casterwheel k', and at its inner end near the main Wheel another arm, k2, at a slight'angle to the former, for more effective leverage, but extend- 9o 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-n wlieel, controlled by the link from said axis,

shall keep pace with that of the main wheel, los

and the grain end of the platform rise and fall parallel with the stubble end.

Now, 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 |05 y frame-bar immediately above, and if the raising and lowering leverH is manipulated in the appropriate direction this frame-bar will lift the platform concurrently in front and rear;

preserving its fore and aft parallelism. Mean- I to while, as the main wheel must relatively sink, itwill operate the rock-shaft through its linkconnection with the inner arm thereofand will move the grain-wheel down acorresponding distance, so as to preserve the endwise paralt 15 lelism ot' the platform to its original position; but supposing. that it is desired-to tip the platform upon a given vertical adjustment, the

raising and lowering lever H will remain untouched, supporting the frame-bar, the rear o f 12o the platform, and the tipping-lever l at their fixed height, and thelatterlever will be moved upon its pivot, so as to raise the front of the platform or to lower it, as may be desired.

Eitherof these adjusting movements will cause a iiexion of the draft-tongue upon its pivots, which will be compensated for by the play of the framebar in its keeper and as to the seat by the play of the arm therefrom in the pendulum or other guide upon-.the tongue, while, 13o as beforeintimated, the prime pinion will be kept in mesh with the main gear by the action jot' the radius-arm from the bracket'sleeved upon the main axle and supporting the raising and lowering lever.

It is evident that the frame-bar, instead ofV being pivoted t the draft-tongue at the front end and playing in a keeper on the platform at the rear end, can, with the same effect, be pivoted to the-platform or a bracket therefrom at the rearend and play in akeeper on the drafttongue at the front end. Therefore'whenever it is qualified in the claims hereinafteras 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 be omitted and some other compensatory device adoptedasaslot in the platform or a raised keeper having rollers between which the bar plays.l

The main gear may be fixed to the main Wheel, as in many harvesters now in use, in

`which case the llatter wheel may run loose upon the axle; but, as already stated, I prefer' L, so that it shall he driven in one direction only. In order to permit this backing-ratchet to be thrown entirely ont of action for transporting the machine, it is constructed as shown in Figs. 5 and G--tbat is, a disk, M, is pinned to the axle on the inner side ot' the gear-wheel, completely closing theratchet-chamberg therein, so as to shield the mechanism within it. From the hub of this disk,'within thechamber, is an offset, m. having a cylindrif'ornl recess, m', with an opening to one side. Within this recess is set the cylindrical head u of the dog N, having its tongue passing through and Vplaying Within the lateral opening. The head is chambered to receive the coil ot' a spring, n', one end of which bears against the hub and the'other against the tongue of the dog to force it ont into engagement with the teeth of the ratchet g2. 'Near the point of the dog an oblong slot, m2, is out through the covering-disk lon an arc concentric with the axisof the dog.

A cam-button, O, is placed exteriorly to the disk, with its spindle o entering throughlthe slot to a pivotal seat in the end'ot' the dog, and

its cam or latch o' restingalpon the face ot' said disk. When the dog is in engagement the spindle ot' the button Will be atone end of the slot. In order to disengage it, the button is Upon the outer face ot' the gear-wheel are lugsp, to which is bolted the swiveling member or gimbal of a telescoping tumbling-shaft, P, driving the rake-cam located at the inner front corner of the platform.

The prime pinionshaft, mounted, as abovementioned, in bearings on the rear of the platform, with its pinion meshing with said gear and` kept in engagement therewith by the radins-arm of the bracket-casting on the main' axle, is provided immediately beyond the pinion with a beveled-gear Wheel, r, which drives a beveled pinion, r', fast to the end of the crank-shaft It, running transversely along the inner end ofthe platform and beneath the tumbling-shaft until its Wrist-pin is brought in proper relation to the heel of the cutter-bar.

Thus` the main gear, driven immediately from shaft connection, and the cuttencrank-shaft by means of the prime-pinion and single set of miter-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 ot' t-lie main wheel, the latter is made daring 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 oir-Within the main-Wheel rim. 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.
