",-IMPRGVEMENT In'. HARVESTERS.

B 1t known olla-two, LEANDEB J. McConmoii, WILLIAM' R. .BAKEman-d LAMBERT ERPELDING, all of Ghicago,tlie county of @ook and State of Illinois, have .invented oer# tain newpand useful Improvements in'HarlWesters, of Whihthe following is a full, clear, and. exact description, reference boing had to the `aleeolnpanying drawings, which make part 'of this specification, and in which "Qligiire 1 represents a plan or top view of afharvester toy `which our improvements are milled v Fig. il represents a view,.yin` elevation, of the inn'' or vgrain side of the saine.

Fig. Sie a diagram, showing the operation ofA the devices for lifting the `outer end of. the

linger-beam. 'Fig'. 4 is a front'view of the coimterr-.shaft and shipping 'mechanism detaehed; Fig. 5, a' section throng-h the roller which snpports'the heel of the linger-loeam.l Figs' and 7 show the details of the device for adjustingthe tongue.

Our. invention 'relates tov that ola-ss of? liarv'esters lnownas twomfheeled liingedjoi'nt p' maeliines; and.onrinventioneonsistsin eerftain novel de\f'ioes,here1nafter fully described.

Inthe `necompanying drawings, our improvements aref-shown asadapted toareara aehine, such as that shown 'in the patent of MeCormiok and Erpeldin'g, dated Jari-` Iilary15,1867, and numbered $1,228.

A stout main frame; A, is.- mounted on two driving; and supporting Wheels, E, turning loosely on an axle, l). snpplementaryfeme, l y in proper bearmain axle and coincident with tlreooiuiter- 'shalt B. zlhe inn-er llongitndiintl framepieee C' extends baofkwartllieyond the other parts ofthe snpplelnentnry frame, and 'supports stirrnp,ll which entends' below the. frame, as L` hewn in liigs. 2 andB. The linger-beam G is provided` with a suitalilsoutting apparatus, and rigidlyseourecl to a shoe, l, which is pivoted behind the linger-beam to a swivelnigpin, h, Fig. 1, passing horizontally through the stirrup E. The front endof the shoe is jpivotedl to an arched coupling-ber, F,Whio.li extends up over the supplementary frame,

axially, and\'to rise and fall at .either conformfto lmdnlations of the grounihns is Well understood. Theron-r end of the. shoe v ternoinateslin an arched `recess, i', which forms end, to

a shield or covering for an oval roller, I, which.' toi-ns in bearings in the shoe. The eye oftlns roller is made largerthan the axle which goes through it, and has a hollow wooden plug or bushing', i', inserted in it, as shown in Fig. 5.

.By this mode of construction We insure a snug lit, and preventthe roller'froin Walibling in' its bearings, thus holding the finger-beam steady and at a nniiorrni'height from the.

. ground.

A lever, J, is pivoted'on the swivel' yeholt or pin. h, and connected Withthe arched brace F, under Whioh it passes. This lever extends Withineasy reach of the driver, (who sitson the main framelgy and is provided with a springinclination to the is pivot/ed to plo f i end of which is oonneeted with a (log or ben-t lever, L, vibrating on the swii-*el-pin h, and

Withits Jtoe acting on a h'orn,.`l, Fig. 1, pro--4 ject-ing' from the shoe H. i.' The'rst effecti of liftingthis lever K is to depress the toe and horn l, and thus lift the divider enel of the linger-beam, as shown in ,Figa` 3.y The oont-nued upward movement ofv lever K lifts the supplementary frame and the heel end of the linger-beam entirely from lthe A gromnl, as shown in Fig. 2.

The stirrup E, it will lie observed, extends mneh lower than in the former patent' of J airnary 5,1867, above mentioned, and the sx ivel-pin il, passes through it parallel to the i inlger-benin, instead oi' transversely, as in tia-l; potent. The looking-lever in that patent was arrangedparallel with the :linger-beam, and merely prevented. the divider end from .do-

eonld not prevent it from desoending-belowia. horizontal line In the present machine, on the oontriliryV the-lever L is arranged transversely to the son l soendino below the heel ofthe linger-beam, but

finger-beam, and acts on the horn i so as not l only to prevent the divider from falling below' a horizontal plane; but to elevate the divider this result. g

` We are also aware that the speed of the A gearing has been varied by using two pinions K endof the cutting apparatus, at the will of the driver, which, in practice, we have found a useful improvement. v

-The tongue M is pivoted in a socket, m, with diverging sides, by a vertical bola/m?, as shown in Fig. 1, to allowa slight degree of lateral play. A corrugated bracket7 m2,

is secured to the front crossbeam ofthe main frame, and has a ledge, ma, projecting from it. A corresponding'corrugated socket, m, is secured to this ledge by a vertical bolt passing through the tongue, and through a slot inthe ledge, which may thus be adjusted laterally, and locked bythe .corrugations to regulate the angle of the tongue to the frame, and 'thus counteract side draft, and alsoy cut a full swath on side-hills.

. i Internallygeared spur-wheels N on the 1n ain wheels drive corresponding pinionsu on the counter-shaft, with which theyare connected bythe usual backing-ratchets. A bevel-wheel, 0,011 this shaft drives a corresponding pinion, o, on the crank-shaft P, which drives the cutters -iby a-crank and pitman in the usual Inordertovary the speedl of the. cutters, when desired, we secure the pinion o on its shaft by a nut, o', and feather and key, Fig. l, which are easily ren-lovable, so as to allow pinions of different sizes to be substituted one for the other.

' In order to accommodate the bevel-wheel() to thisl change, it is provided with a collar, which slides endwise on the'counter-shaft, and

'is held in'place by a set-screw. A sliding clutch, R, of well-known form, serves to' throw the bevel-Wheel into and out of gearing. The shipper r must, however, move farther in one direction when a larger pinion is used on the crank-shaft. In order to hold it in either position, we form three notches in the catch-plate' '3, which notches arel so arranged as to accom- 4e `f l sasso ways; and do not, therefore, claim anything more than our specific devices for attaining on the crank-shaft in combination with two gear-wheels on the driving-shaft.

W'e are also aware that the speed has been varied by moving the shaft sidewise in its bearings to accommodate pinions of di'erent sizes g" and do not claim these modes of varying the speed; but we know of no device previous to ours of a bevel-wheel sliding on a counter-shaft to accommodate pinions of differentsizes', applied one at a timeon aora-ukshaft.

l. The combination, substantially as set forth, in a two-wheeled harvesterof a tongue.

with its rear end pivoted, so thatL the tongue can play laterally in a ksocket over the main axle, a corrugated laterallyslotted bracket on the line of draft can be varied at pleasure. p

2. The shields S, constructed as described,

attached to the main frame, and inc losing the countershaft, the pinions which drive 1t, and

the backing-ratchets, for the purpose set forth. 3. The arrangement, as set forth, for lioint.

operation of the counter-shaft, the adjustable bevel-gear 0, audits sliding clutch with the nut and removable pinion on fthe front end of..

the crank-shaft, whereby we 'vary the speed .of the cutters -Vby using a single 'gear-wheel on the counter-shaft without moving either shaft. et,K The arrangementyas described, for joint operation, of the finger-beam, thc shoe, and the stirrup with-the'y horn l and dog L, whereby we lift the divider end of the ingcnbeaxn first in raising the cutters.

5. The combination, as setffortln'of the shoe Hand arched shield z with the roller, provided with woodembushing.
