Both wheels,D- and E, are, theiet'ore,drivingwheels when the machine is cutting grain or grass, and, besides the=weight of the machine .itself, the weight of the driver is divided on the two wheels, and I thus availivmyself-of all the weight'tothrow. friction on thedrivingwheels,;to preventthiem from slippi w. The wheel Dis vprovided withcogs on the inner edge of jits perimeter, which gear with the cogsjoi' a .pinion, F, on; one endot' the shaft d, and on the otherend of this shaft, (1 there is a bevel cog-wheel, G, which worksinto ,a',pini0n, e, on the vertical shaft f, and tolacranlrnear the lower end'ot' said shaft f is fastened one end of the rod g, the other endofsaid .rod

being connected to the heel of the cutter, to

The rear ends of these rods are difierently'coii nected to theiinger-be'am and extension-bar, The one,;k,i's attachedto' said beam," or to. a, how a or; loop, u, attached to the beam, by a 'joint, as atm so that whilesaid' rod k may fully sustain the drag of the cuttin g .appara ins, it wiil 1not in any manner check'nor cramp the free movement of the jsa ne'as it rises and falls .to adapt itself to the'incq'ualities of the ground, 'or' to pass-over anyintervening'oh stacle. The otherr0d,".k, though hinged with a fastening at its front end, that is in efi'ect fastenings. are' generally,f.has its rear end passed through" the outer: end of the exten 'j'sion-bar I, and held thereto by a screw or nut,

, This featurein grassharve'stin g machines is particularly essential, as it does not leave" so much ground unmown as when the fingerbar is simply hinged to the main frame, as] heretofore done, so that when raised at theheel the point, or other end, would be raised to agreater extent,

By my construction'the cutting a ipar atus can rock upon the ground in; the line of its,

length, and thus mount andpass over in}- equalities on the surface without raising jthe whole of said apparatus to'do so'.-

justs itself at either'end to the surface of the by the" main frame, but is perfectly guided in its forward movement or path by its-conned tion to saidframe; or, in other words, while the said beam is free to rise or fall ,at either of I movementto, its-other end, yet laterally asrigid'an'd as readily controlled by the main frameas though it were afixed immovable 7 part thereof. So, also, may the wheels of as [main frame rise and fall with the inequalities of the ground without communicating that motion tothe finger-beam, forsaid beam adaptsitself'tothe surface which it passes. .over without being influenced 'injuriously by the motion of the main frame, but at the same time the-main frame directs and guides said beam in its forward motion, but not in its upand-down movements, the latter being governedzhy theiground"overwhich it is passing,-

andvaryin'g with the undulations of the same.

While the two rods k k s'ustain the drag of thetinger-beamin its onward progress,-, they -d0-.iiot sustain the lateral tendency of said beam, though they may do so inpart; and to l prevent their lateral movement I use another bar, m, which is attached to a piece, J, (rigidly connected to the main 'frame,) by one. of its. ends,-and to the heel of the finger-beam, at n,

by its other end. The rod or bar Zr might more properly becalled a drag-bar, and not a f brace, though at times it may be either but therod. or bar 10 is rather ahrace than adragliar, and, as a brace, might berigid to a very great extent. The other rod, on, holds'or braces, just as the tendency of the f nger-beam may be fortheti ne being. 1 f

' My cutteruis what is commonly called a short cutter, for thereas ou that its outer end is terminated with a cutting section, and. it: has heretofore been common to place a blank sectionbeyond the last cutting section, for the;

purpose of removing the 1 clogging matter whichis forced into the slot of the divider by ,the last cuttings'ection, This blank is usually called a clearer, and is the same inform H v theblank we; the-inner end of'my cutter; It is By-thus hanging the cuttingapparatus me free to; rise-or fall with every elevation or -de-.

This is clearly shown in the drawings, Figs. 1 and S.

The objects of these several parts being thus distinctly set forth, it .will be obvious that their equivalents may be substituted for any of the ordinary well-known mechanical appliances, I should deem them as'involving the general objects of my invention-viz., the application of theloose finger-beam to harvest: ers.

K is the driversseat. It is connected to the supports or rails 0 0, which extend from front to rear of the frame, by loops 2) 11, so that the driyer may, without rising from his seat, and with the aid of his feet, move said seat forward to balance'the machine. This is very necessary in a harvester, the cutting apparatus of which rests upon the ground while in operation, and is supported upon the frame fortransportation because when the cutting apparatus is borne by thefraine, the weight of the driver must rest uponthe opposite part of the said frame, in order to counterbalance the weight of said cuttiug apparatus. v

A seat for the driver has been made sus ceptible of adjustment heretofore; but said seat, when adjusted, was permanent, being secured to the machine by bolts or their equivalents, and its position could only be changed by removing said bolts, so that the scat might be detached entirely from the machine, replaced in its new position, and again secured; consequently the driver could not move himself forward or backward, as the exigencies oi the case might require; but by my aid the machine, by shifting his seat and weight forward or backward at any time when it may be necessary, without removing said seat from its support. To a standard, L, on the right-hand longitudinal piece A, is hung a-lcver.M, to the rear end of which is attached, by a chain or link, heel. By this lever and chain the cutting apparatus may be aised from the ground bodily by a single movement of the drivers hand, to enable it to cutting apparatus for transportation. Near the front end of the lever M, which is provided with a handle, 37, and a spring-catch, s, is an upright piece, 0,"supported by the frame of the ma-- chine, and provided with a suitable number of notches, t, into which the spring-catch 8 sure the return of th'e-(intersection:into v "the iwheel-s so as Bto-r lace;.the

Q, is a shield-brace, extending from the front transverse bracket J. The position of this brace is such as to cause it to strengthen the said bracket, and at the same time act as a shield to protect the crank-shaft and bracket from contact with obstructions of any kind which may be upon the ground in the line of the machines movement. Having described my invention, what I claim as new, and desire to secure by Letters Patent, 1s-

1. Flexibl y connecting a laterally-projectin g cutting apparatus, which has its cutters reciprocated in straight lines through open-slotted guard-fingers, to the main frame of a mowingniachine, substantially as set forth.

2. The main frame and the gearing which drives the cutters of r a mowing machine, mounted upon two driving and supporting wheels, a draft-pole to draw the machine by, rigidly connected to said beam and "cutting apparatus, (the cutters of which reciprocate through open slotted guardfingers in straight lines,) flexibly attached to the main frame, in such a manneras will permit said finger-beam and cutting apparatus torcceive all their up-and-down movements from the undulations of the ground over which they are drawn, substantially as set forth.

3. In a mowing-machinehaving a lateral-lyprojecting finger-beam flexibly connected with the main frame, a lever so arranged that the driver can, while occupying single movement, raise the finger-beam and cutting apparatus bodily from the ground while the machine is in motion, to pass over obstructions, &c., substantially as set forth.

4. Connecting the-lever by which the cutting apparatus is raised to the heel of the finger-beam, substantially as set forth.

5. In combination with the main frame, which carries the gearing to drive the cutters, and to which is flexibly connected a laterallyprojecting finger-beam provided withopenslotted guard-fingers, and cutters reciprocating across said lingers in a straight line, a lever connected to said finger-beam, and having its fulcrum upon the main frame, so that when the finger-beam is raised by means of said lever, the weight of the entire cutting apparatus will be borne upon the main frame, substantially as set forth.
