'To all whom it may concern: y

Be -it known that I, JAMES S. MARSH, of Lewisburg, in the county of Union and State of Pennsylvania, have invented certain new and useful Improvements in Harvesthig-Maehines; andl do hereby declare that the follow f ing is a full, clear, and exact description thereof, i reference being had to theaocompanymg drawings, making a part of this specification, in

Whieh'- Figure 1 l i,sa perspective Viewl of my improved reaper and mower arranged for reapin g; Fig. 2!v is a perspective View of the metal platform, with its tool-boXt-he gearingbeing' detaehed. Fig. 3 is a perspective'yiew of the 'guard for the drag-bar and inner end of the platform. Fig.'4, Sheet 2, is a plan View of Fig. 5, Sheet 2, is an elevation through the inner end of the platform.

`Similar lettersof referenceindieate corresponding partsin the several gures. v This invention relates to a convertible harvesting-machine which, can be used either as a reaper' or mower.

Themain object of my invention 1s to employ,

instead of a draft-frame, as hithertoconstructed, a metalplatferm, which is applied upon the aide of two transporting-Wheels,v and adapted' to aiford supportsfor the gearing -which trans mits motion tothe sickle,v also a support for `the drivers seat, also a support for the draft?v pole, and also which is so constructedthat the tool-box forms a brace or means for strength- .ening said platformv longitudinally, and admitting of its being made very light andsubstantial, as will be hereinafter described.

Anotherfobject of my invention is to con-` neet thegrain-platform to the supporting-platl form, which is. between the transporting Wheels, in such manner that theattendant, while riding upon the machine, can elevate or depress the front end ofthe grain-plattbrm atpleasure by means of Alevers, to which the frontend of the'drag-brace'is pivoted, as will be hereinafter described. Another object of my invention is to pivot the front end of a drag-brace, which is applied toa plntfbrm that is mounted. upontWo easterT wheels, to adjnstinglerers whiclrare under 'the vontrol of the attendant riding upon .the

machine, fory'the purpose of alloivingof the elevation and `depression of 7the cutting' appa ratus or nger-beamivithout tilting'or cant ing it at either end, aswill be hereinafterf'dei scribed.

To enable o struction and operation.f

.In the accompanying drawings, )AA repref v sent two transportmg-Wheels, Whiclijare ap-` plied to an axle, A1, in sueh manner that when the machine is backed these wheels shall turn loosely upon it; butywhenthe maehine]` is moyed forward the axle shall turn with the Wheels. Upon the axle Aametalplatform is mounted,

which .attends,suitable distances both in front y and rear of thisaxlefas shownin'sFigs." land 4," soas -to afford a means "for connecting the grain-platform B to it at both ends, 'aslwill be y hereinafter described. .p This platform is eastA .Withthefollowing parts; a is thetool-box, which isarranged'on the inner side of the platform G in adireetion with'its length, for the purpose of containing the tools which usually accompany the ma-A u chines, and alsoffor ythepurpose of strengthi ening the platform andadmittingof itsbeing y made verythin and light.

Directly oppositethis toolbox a a 'flange or l guard7 a', is constructed, upon the-outer edge of the platform Cpvliichalso affords strength to it nd serves as a guard or fender' to' ,the

gearing.

v Elevations c care also cast onthej-npperf surface of t this platform, for `the purpose of receiving the draftpole andY adding 'strength Where the greatest strength is required; -V p On the outeredge ofthe platform C,.near

its rear end, half-bearings c1 alare for1`ned, for receiving and serving, in connection with caps,

las means for applying the shaft of the driving-gear c2 tothe platform, `which shaft transmits motion to the crank-wheeled fromthe .bevel-Wheel c3. lThe short shaft-'of' this bevel- Wheel c3 maybe appliedto the platform C in any suitable manner. VThere may 'also bean elevation o'r ril formed around the edge of the-platform C' for strengthening it atythis poin-t. .i l H .y By. thus constructing' the plfatfor'mfot one chers skilledfin the art to understand my invention, vIjwill describe its oon-'- 'piece of metal, I am enabled to dispense with brace, E, `is rigidly secured, whichlproceeds,

When the machine is used as -areaper the a draft-frame as hitherto constructed, and obtain a much firmer support for the gearing .and lother parts of the-machine which'it is necessary to apply to said platform. v I am also enabled to use short shafts for the spur-.wheels c? and-c3, and to drive these .shafts by means of an inside gear-wheel, A3, which is applied to the axlel of the transporting-wheels, as shown in Figs.. 1 and 4.

To the inner end'of the finger-bar D a dragforwardv and upward, and is pivote'dait its front end to a 'transverse arm, Dl, which is pivoted at its `outer end to the front 'edge of the plat- 'form C, and 'near the .outer corner thereof, as shown in Figs. l and 4. l l' The ngerfbeain D is again connected to the,

bar, D2, which is pivoted at its lower innerend to the drag-brace E, near the rear end thereof; and at its upper and outer end this brace-bar D2 is again pivoted to the platform-C, near its rear outer corner, as indicated iirFigs. 4 and 5.

Thev arm l)1 is' connected by ai link, d1, to a crank; or right-angle lever, d2, which is pivoted of the platform C. rDhe plate Fis constructed in the form of a segment, and the' pivot of the arm Fl of this lever can bemade to. catch and thus sustain the forward end ofthe drag- The arm or l.handle Fi is pivoted the up` light spring so that it can be easily handled by the attendant while-sitting' upon um seat of. Th'e two transverse bars D1 and D2 allow the iinger-beam to vibrate freelyY about the 'outer joints, also to be elevated or` depressed.

When the raking attachment and the grainplatforln are detached from the machine, -I ein ployahandlever, F2, in conjunctionwiththeforward leverabiove described, for the purpose-of enabling the attendant, while upon the seat'C,

aswell as to tadjustthe height of cutv and the pitch of the sickle. This .lever F is'pivoted to aplate, j inthe fonnof asegmenm-,and vit has a groove segment secured to its lower end, to f which a chain, f', is attached, that islfastened to a rod, g. This rod g is secured to, and projects outfin rearof, *the bar D, beneath' the pitman-rod Gr, as shown in Fig. 5.' so that by the chain f' will lift the ngerbeam. A tooth and ratchet are used in conjunction with lever; -F2 for fixing this lever in any desired position.

rear lever F2 can .be detached, -the forward lever being left 'on the platform C to enable. the

driver to raise or lower the front part of the platform B with its cutting apparatus.

In rear of the fingersbeam D, andapplied to support the platform B,'are two caster-wheels,

n n'. Theinner one, n; is pivotea to uw vertical -guardboard of the vdivideiyand the outer one','H, is appliedto a' short beam, which is vsecured tothe inner forward corner of the platform. Being thus supported, the'platform can be raised vor lowered, by means of the forward lever F1v uniformly-that is .to say, both the inner an outerends'of thenger-beam,

vand the platform which is secured to' it, will be elevatedfor depressed alike, neither endbe- .ing allowedto sag. .Theaxeszof th caster# wheels become the fulcra about which platform is a" 'usted while feutting grain.

In-Figs.l 1, 4, and 5, vJ represents a guard or" fender, which extends from a point which'is near' to front end ofthe dragfbrace E over this bar, and curves around the arched standard K, so as to gather the inner standing grain and press it up tothesickle, and also prevent the grain from vbecoming entangled with the v gearing and rake joints. This curved portion ofthe guard J extends over and is suitably at-` tached to the platform B, while'. its straight .portion extends over and is suitably secured l .to the drag b ar or brace E, as shownviu Figs.

l and. `This fender'fJ should extend well up at the point where it .protects thegearing of the rake; but it should not beso high as to kinterfere with the horizontal sweep'of the rake and beater or reel-arms.. l

I have represented a rake and reel or-beater attachment applied to the machiney which vI have above described.; .but'as other raking attachments may be used in conjunction with my machine, I will not here particularly describe the construction-of the/rake shown.

It will be seen thatv the rake-arms are `pivoted to ja crown wheel which is 'supported 'upon the outer forwardcorner ofthe platform,

and so arranged and operated that they sweep v around over theplatform, then rise to a verti'- cal position, and descend again in front of the cutting apparatus, so as to sweep the grain,
