Whenever 1t maybe expedient tov use'one or more of the several partsor branches oi said improvements separate from 'the rest,- such lpart'or'part'srnight he used in connection with frames and gearing more con vement than those herein described, which are proportionedand arranged with reference to the-use ofthe whole .of the parts together; several parts -oi' the said Aimprovements are and it is obvious that applicable to various other reaping or mow'- One mode oi' applying each of theseimprovements vto practicalnse. is shown in this machine. It is therefore unnecessary to specify the lnannervcf applying the parts, respectively,

the ordinary skill of a constrncter is sniiicient for thatv purpose.

In machines tor mowing, as usually constructed, Vthe finger-beam bears far`too heavily upon the ground, and it is desirable that the linger-beam, especially ii its connection withthe'l main frame he flexible, shouldnot bear upon the ground with any greater pressnre than is necessary to prevent it from-bonnein g up whenever it comes in contact with slight protuber'ances, as any excess oi vpressure be yond this onlyeauses the beam to hug the ground niore .closely, increasing the friction and direct and side draft of the machine withontanycountervailingadvantage.

in a machine vhaving a'finger-bea-m connected to the main frame by a eouplingarm,that end of the beam which is next the gearing has to support cile end ot' the shacklefbar that drives the cutter, and one .end of tne coupling-arm, s l

and is thereforehorne upon the ground lmore heavily than the opposite end, and prevented from rising 'as readily and conl'orniin g as freely as it otherwise would yto the nndulati'ons of the ground.

To overcome -such diiiculties is the object of the invention which is the subject ot this which consists, first, in combining with that end of the finger-beam next the main to prevent it from` bearing upon-the groundmore iieaviiy than the opposite end', thus rendering the press-y v to other machines, vas
