kind cannot work perfect unless. constructed ot' the'driving-wheel. i. l

`above-nientoned position I ain enabled tocon-l structiny machine in such a ma-nner that all and every part et' the gearing works in a direct line with' the axle ot' thedriving-wheel. This, it will be sceinisabsolutely `necessary in this arrangement, for were it placed in any other position it would be impossible'to operate the sickle by means ot' the eccentric and sliding machine.

sition l am enabled to use ambiti-friction wheel ot' greater diameter than I could were said shaft `placed in any other position. The advantages ot' a. largeanti-frictionwheel are obvious, as all mechanics aie acquainted with .the t'act that the greater the diameter ofthe wheel `the less `the greater the ease with which the wheel overcomes the resistance ot' hogs, mounds, stones, and all other impedimentsfound on uneven surface. i j

, Another advantage ot' placingjthe sha it at the highest pointpossible is to give the headbeseen that were the shaft placed at a lower point the head-iron could be raised only to a Upoint to correspond thereto.

The object ot' extending the line-shaft entirely across the franieot'the machine is to forni an open unobstructed space between the driving-wheel .and the anti-friction wheel, and also in the peculiar position herein shown and described. Said shaft is also provided witha bcyet-wheel, t), which takes into abevel-pnnon,

- el asclearl 'showninFirsandii. vSaid rinion is placed upon a shaft, E, wliichis providedwith a crank, j", at. itslowerend. Said crank is prt'widcf-l with an anti-friction roller, g, Fig. 2, which works in a yolte,li It. (See Fig. 2.) Said yokcisprovided with an adjust;-l able back, as seen in Fig. 4, and isailinsted bi;

desirable object to obtain, as machines ol this with an equal weight each side ot' the center Second By'placing the said shaft in tlie pinion-shaft without destroying the adjusta-l bility ot' the head-iron or the balance `ot the` Third. By placing the lineshattin said poresistance isA experienced from friction while the wheel is 'passing over even surface, and

K is the linger-bar, which is attached to the l head-iron, as seen in Figs. l and et, and is coniposed of two separate pieces-one ot' wrou gh tiron and the otherof cast-iron. The wrought har is placed on the top ot' the casthar and secured lirinly to it. Theohject of thisarrangement is to prevent the linger-har from breaking or springing and setting, as it is liable to do, the former when made entirely ot' cast-iron and thelatter when made cutirelyof wrought. l

iron. i L is the fingerorsickiti-guard, through which the sicklereciproc'aifes which is attached to the linger-bar, as seen in Figs. l and 4..

To the grain end ot' the linger-bar I` attach a shoe or shield-piece, lll, for the purpose of protecting the tin-gers and sustaining aportion ot' the pressure ot the machine upon thc ground. n i

N is the head-iron, which slides in suitable ways, n n, Fig. l.

O is the anti-frictiou wheel, having;` its ,fixle o attached to au upright bar, l), which slides in suitable ways,p`p, Fig. 1. The top ot' said har is bent in Ithe manner seen in Fig. 2, and presses against spring 1t, as seen in Fig. 2.

'r r are set-screws which take into the crossheam S,and are used to set the springt at any desired height above it.

The advantages of the anti-friction wheel,

' wheel weighs about four times as muchas the opposite end when the machine is in order for reaping'. Therefore it will he seen thata suftieicnt amount ot' weight will rest on the driving-livel to operate the sickle while reapine. ly this arrangement l evade the necessity of placing a grain-wheel at the grain end ot' the linger-har while reiipiug, thereby ohviatinIl in a great measure the side draft and allowing' that portion ot' the machine to be made much lighter than it otherwise could he. The wheels in a working machine are live feet apart. The pole is placed ,at the center hetwcen them. When the machine is moved forward by the tongue the grain end ol' l he machine will incline torward of the. inaster-wheel end; but when it cornes in. contact witlrthe grain it will incline haelt to a right angle with the tongue. This advantage could not he obtained were the anti-friction wheel lremoved and one placed at the grain' end of the sickle-bar, as in other reapers.

T is the reel, which receives its .rotary motion troiuthe line-shaft by lueansot the heltt.

.U is a lever which isl used for throwing the 'machine into and out of gear.

V is the pole.

W W, Fig. 3, areA screws which are used. -r

screws r r down on the spring until the finger-h har bears the. desired weight on thegrouud. This can be ascertained by raising the lingen piece with thc hand. About twenty-tive pounds is sufficient for cutting closeau even surface; less or none at all on rough surface. This, however, every operator will decide for himself. 1f the shoe ot' the linger-half` raises ou higher surface than theuiachine, the spring, being,r on a strain, helps to raise it. This prevents 'the finger-har from sprineinff. Consequently the sickle-bar or knife-bar reciprocate unobstructed. This obviates in a great incasure the knife choking and clogging. When reaping` l force the springdown. This, however, is to agree with the adjustable features ot' the head-iron for high or low cut.

The machine, as seen in the drawings, is adjusted for mowing. chine forreaping, take out the screws W M'. This done, all that part ot' the machine shown in Figs. 4 and 5 (excepting,r the pinion only, which remains stationary and allows its shaft to slip through it) can he raised and secure; at the-desired height without affecting tho -gearing of the machine in the least. Thus vw,

see that in my machine are embodied all principles ot' a perfect mower and reaper. The perfect harmony in which this truly mechanical arrangement operates is `enough to warrautQits due appreciation by all who examine into its merits.

`What I claiuras my invention, and desire to secure by Letters Ratent, is

1. Placing the lineshtift directly above the vertical center of the spur-gear ofthe masterwheel, in the manner and forthe purpose here-Y in described.

2. The adjustablev anti-tiiction wheel, in combination with the spring 1t and adjustable setscrews r1', in the manner and for the purpose herein described. 7
