DIVISION A.

' To all lwhomA 'it may concern? the accompanying drawings, forming part of E this specification, in which- Figurel. is a front perspective view of my improved machine as arranged for cutting grain. Fig. 2 is a 4rear perspective view of the same in the form of a mower. Fig. 3 is a side elevation of the same as arranged for transportation. Fig. 4 is a perspective view of the main frame, detached. Fig. 5 is a plan of the top nthcpost on. which the rake is mounted. Figs. 6 and 7 are views of the outer divider.

The invention embraced under this patent relates to the harvester whether used as a self- -raker or otherwise.

My rst improvement consists in a. novel construction of draft-frame with reference to the gearing'and double driving or supporting wheels.

My second improvement consists in a device for atfordin g protection to the main crankshal't and strengthening the main frame.

, My third improvement consists in a novel manner of employing a removable tongue or draft-pole upon both the inner and outer sides ofthe inner drive-wheel, whereby the machine is very`e1fectually, in connection with other changes made. adapted for either mowing or reaping at will. v

My 'fourth improvement consists in a device for permitting `the finger-beam to turn freely,

lso as to elevate the points of the iingers or depress the same, and also so as to permit the nager-beam to accommodate itself to the surface of the ground and duringsuch movements afford a bracingsnpport horizontally to the finger-beam, the said device also permitting the cutting-apparatus to be turned up edge'wise and carried ou the machine, all substantially as will be hereinafter described. r

-My fifth improvement consists in' supporting the weight of the cutting apparatus and all attachments thereof at a point between the two drive-wheels by means ofrdevices which will be lhereinafter described.

in gs.

My sixth improvement consists in construct'- iug the innerl shoe with'a rear extension, forming a means of attachlnent between the cutting apparatus and the platform, and with lugs or ears, which'form a. means of attachlnent by a compound joint to the pendulous drag-har, all as will be hereinafter described.

My seventh improvement consists in providing for changing the draft of the machine from the inner to the outer side of the outer drive-wheel, and'vice versa, and at the same time providing for changing the point of snpport of the cutting apparatus, as will be hereinafter described. r

My eighth'improvement consists in a. com'-,

bined gnideand fender support, made in one piece in such manner that it serves as a means whereon to ad Just tlieen'der, and also, through the aid of an innerhorizontal wing, forms a ,guide for theouter end ofthe short grain sickle, thus obviatin-g the necessity in a com- -o'r thereabont, of the vgearing-frame, the said y jointand drag-bar forming the connection ot' the cutting apparatus with the gearing-frame in such manner as to permit the cuttin g apparatus'to turn'on its axis to elevate or depress the points of the 'gua'rd-ingers`,or to fold'the beam against the frame for transportation, and also allow the lcutting apparatus to accommodate itself to undulations of the ground while the grain is being cnt, all as will beherein'after described.

In order that others skilled 'in the. art to which/my invention appertains may be ena; bled to-fully understand and vuse my invention, I will proceed 'to describe its construetion and operation, wit-h reference to the draw- 'Lhe main frame A A is cast in one piece in the form represented in Fig. 4, the ends thereof ,being left .disconnected or open to facilitate casting and to reduce the weight.

B B" are two drive or supporting wheels,

, square heel of the pawly I) to hold it eitherin slots formed in its axis, either for conforming to the undulaa position between the wheels for cu 4it may be placed'. f

adapted .to turn. on the axle O, but one or bothA furnished with a pawl,b, taking into a ratchet- -wheel, b'on the axle so as to impart rotation thereto when the wheel is turning forward.

b2"represen"ts a spring bearing4 against the or out of gear inwvhichever set. i.

C' is the main gear-Wheel on thc axle C, which gears with a pinion, d, on the transverse shaft D', which` carries at its other end a bevel cogwheel, D', gearing with a bevel-pinion, e, on the crank-shaft E.

E' is the crank-wheel, mounted onthe rear end of the shaft E, and imparting' motion to the cutter F hy means of a pitmainj', which is provided lwith a swivel,f, formed of a screwt'hr-ead and nut to permit the rolling of the tin.- ger-beam without straining or binding the cutter. t

a represents a iange castupon the'lnain frame A, for the purpose of imparting additionalstrength thereto, and also protecting the crank-shaft E.

G is the finger-beam, attached at its respective ends to the inner sh'oe, H, and .the outerA shoe or divider, II. The-inner shoe, H, is pivotd by its center at h tothe drag-bar I by a` universal joint, and at its respective ends to guides h' It', which work in* vertical dovetail pendants t' t' on the drag-bar, in such a manner as to brace the beamhorizontally, While permitting it to turn freely on position it may he tions of the ground-to rise over an obstruction, orto beturned up edgewise, and carried. on the machine in manner as represented in Fig. 3, in which position the point of the divider rests in a staple, 4k, which is in the side of the tongue K.

The 'tongue is attachedto the main frame A lay-means of two bolts, K', passing through it and through notches or holesjj orj'j' at one side of or near the center of the frame, so as to permit the adjustmentof said tongueto ttin g grain, as illustrated in, Fig. l, or on the outside for cutting grass, as illustrated'in Fig. 2. In ei-ther ease or position an extension, K', from the tongue affords-a means for supportingthe inner endet' the finger-beam. Thisv is e'ected in the illustration given in Fig. lfby a chain, J, rising from the outer end ot a rigid arm, J', which projects inward from the beam, and 'in the illustration given in Fig. 2 it .is effected by a chain, J2, pie, h2, in-.the lateral stay-rod H'and vat its upper endto a vsegment-lever, M, fulcrume'd atm on therear end of the tongue, so that.. by raisingA the said lever the heel of the beam may be raised'to any required height. A rack, M', holds the lever M in any position in which H3 represents a-track-clearer,'attached to the divider o r-outer shoe, H', when the machine is used for mowing.. This d evice isf remfoved When'the machine is used for reaping,

| and the combined ofce rendering a short sickle ca ing on a long linger-beam. The ange is so attached atits low'er end to a sta guide and lfender-support substituted r it, 'as shown in Figs. 1, 6, and 7. 0n the rear end of the innershoe is formed a lug, h, for theattachment of the inner side of the segmental grain-platform P. The-saidplatform .is secured to the fingerbeam at suitable intervals by straps O and bolts o'.

N represents a `caster-wheel secured adjustably -to the outer edge of the platform, and employed to carry the same at any desired height.

Q: represents a fender or divider on the outer side ofthe machine. y

Q' is the metallic seat or support for fender. This' seat is placed on top of the outer shoe, H', and forms therewith as'pear-point. From the inner side, at 'the bottom of the support,

a horizontal wing or tlange, q', is formed cast. This flange bolts down upon the fingerbeam G, as shown at q'*,'and also extends for- 4ward over (but free of) Vthe sickle, and thus answersa twofold purpose: first, as a means whereby to fasten the vsupport audits connections to the finger-beam; second, as `a guide to the outer end cfa grain-sickle, it i'n this pableof workthin and so arranged that it offers but little obstruction to the falling grain'. By its nse the fender or dividing device may be thin and all necessity of bulging out the shoe or dividing device as it recedes back from the point is obviated. A l l The support is formed or cast with a horizontal shoulder at g3, sothat the fender or dividing-piece Q may be seated yin line' with the guard around the platform. It also has a vertical extension, q, (shown by. dotted lines in Fig. 7 and in full in Fig. 1,) and to this extension the fender or dividing-piece is pi'voted, as at g5, and connected at its other or rear end by means of a set-screw, as at Q6. The object oli`thisarrangement is to allow the fender to be elevated atits rear end to different inclinations. The set-screwv is inserted into one or another ofthe seriesiof holes q' when the changes are made.

1 have shown in the drawings acombined raking and reeling device; 'but as this application only embraces invention which is to be .used irrespective of its connection with any 'kind of rake, or without reference at all toa rake, I do not deem it necessary to describe particularly the rake and reel. The rake and reel shown will,'however, be found well adapted for use with the inventiondescribe'd.

W represents the drivers seat, mountedl upon the tion. 4 4

From the foregoing description it will be 'seen that'by the use of the rigid arm projecting'inward from the finger-,beam to a position bei youd the inner drive-wheel, and' supporting the'lat'terwith the platform if it be attached from the 'rear of the tongue, lthe ahruptness of the motionsof the cutting` apparatus and main frame'in any convenient posi- 'platform will be greatlyldiminished withoutv restricting their freedom in conforming to undulations of the ground. Thisis due in a great measure to supporting the weight at a point which is between the two drive-wheels. This advantage especiallyresults when the machine; is used as a. renper, as illustrated in Fig. 1.

In mowing` the cutters are left perfectly free to rise and fall, but are raised and lowered by the operator in the manner already explained,

i the tongue being transferred to. a position on the d`rivewheels and their axle adapt the machine to be turned or backed with perfect free.- dom, and also afford ready means for throwing the enti-re machinery out ofgear, which is eiiected by raising the pawls out ofthe ratchets, where they will be held bythe springs b.

The cutting apparatus may be thrown out of gear by moving the transverse shaft D longitudlnally'by a lever, D?, and providiugit with a pm, d, which in one position of the shaft will t in a recess in the hub of the wheel,.so as to impart rotation thereto, and in the other position will permit the shaft to turn 'independeutly of the wheel. This lever may 'be moved by the hand or foot of the driver.

The outer divider, by its peculiar construction, answersas a means whereby to adapt a long mowing-machinefinger-beam for use witha short grain sickle. T liis end may have been attained, but not in the manner and by the means shown by me.
