Figs. 4 to 7, inclusive, reprigidly with said frame, so that the latter is resent certain parts of the machine detached prevented from oscillating relatively to the from the residue, and designated by the same tongue .on the axle of the driving-wheels, as letters as they are in theother figures. the cutter rises and descends in passing over The main frame or driving-platform A of inequalities of the ground, fourth, a lingersaid machine is supported upon the two runbeam arranged to project laterally from one ning-wheels` B B, and is connected with the side of the main frame, and at one side of both stiff tongue C, to which the horses are hitched, the running-Wheels thereof; fifth,alink hinged so that the said frame is caused to travel parto the inner end ofthe finger-beam by a pivot; allel Yor thereabout with the surface of the by means of this link the finger-beam is held ground, instead of oscillating on the arms of' in its proper endwise position laterallyof the the driving-axle. The finger-beam L is armain frame, with the capacity of being raised i ranged to project laterally at one side of the and lowered relatively to the said frame, and main frame, so that the cutting apparatus 'is of having its outer end turned up or down at one side of the said frame and of both the upon the hinge-pivot which forms the connecrunning wheels thereof. This iingerbeam tion between the said link andthe inner end sustains the fingers and cutters ot' the cutting apparatus, and it is secured at its inner end by screw-bolts g g to the upper side of a bar, D, which, being under the finger-beam and bent upward in front and behind it, co`nnected with the finger-beam for turning up the outer end thereof; seventh, a lever conso that the connecting-rod may twist upon its outer end finger-beam through the stitutes a shoe for the inner end of the fingerbeam. This bar is extended forward, and connected with a hook, N, at the front corner of the main frame, so as to act as a draw bar or brace for the finger-beam. The finger-beam is connected with the' main frame by means of the link E, whose lower end is connected with the shoe D of the finger-beam by means of a hinge-pivot, h. This link is also connected with the main frame, so that its lower end may move up and down relatively to said frame without changing its position laterally thereof. By means of this link the finger-beam is held in its proper endwise position laterally of said frame with the capacity of being raised and lowered bodily without changing its distance from the crank-shaft V that drives the cutters, and the finger-beam may also have turned up on or 'down upon the hinge-pivot h of the link, for the purpose of passing obstructions. y

In order that the outer end of the fingerbeam may be turnedup independently of the inner end thereof, the hand-lever M is provided, and is connected with the finger-beam through the intervention of the shoe D. By

operating upon the handle at the upper end of this hand-lever M, the driver on the main frame can raise or lower the outer end of the t iinger-beam, as may be found necessary, in

passing obstructions.

In order that the inner end of the fingerbeam may be raised or lowered by the driver on the main frame, the second lever I is provided. This lever is connected with the shoe of the intervention of the link E, so that the driver, by pressing his foot a upon the front end of the second lever I, can

raise the inner end of the n ger-beam; and by operating upon both levers he can raise and lower the finger-beam bodily, relatively tothe main frame.

The inner end of the finger-beam .may be held at any desired position above the ground y by means of a pin inserted in one of a series of holes made in the link E, and when the machine is not cutting the finger-beam may be turned upright, as represented in Fig. 2, and

vheld by a brace, K.

When the machineis cutting the outer end of the linger-beam" is supported by the stubble-shoe P and shoe-wheel R, which last is connected with the stubble-shoe by the thimble s and bolt s, the bolt being passed through a slot in the shoe, which permits its position to be changed, so that the outer end of the nger-beam may be set to run nearer to or farther from the ground.

The cutters are caused to reciprocate by reason of their connection with the stock or cutter-bar w, to which a reciprocating movement is imparted, by the revolving crank-wrist e, ,through the intervention of the connectingrod a. The rocking of the finger-beam upon its longitudinal axis tends to twist or rock the connecting-rod on its longitudinal axis 5 and, in order that the crank-pin may not be necting-rod, is constructed to .swivel on pivots b, Fig. 6, whose axes are in line with the lon gitudinal axis of the connecting-rod, or, in other words, are arranged longitudinally of the connecting-rod, one pivot turning in av socket in the body a of the rod, and the other pivot turning inA a hole in the cap J of the rod; 'hence,'when the finger-beam rocks on its longitudinal axis or thereabout the swiveling'of the journal-box on the longitudinallyarranged pivots whichconnect the journalbox and connecting-rod permit the box-and rod to twist relatively to each other, and consequently the twisting-strain does not affect y the crank-pin.

The jaws of the connecting-rod at each side of the journal-box are far enough apart to permit the swiveling of the box.

Having thus described the mode in which I embodied my improvements, I declare that I am aware that no one of the members `of which my combination is composed is new when considered separately. I am also aware that a lever has been applied to the shoe of a finger-beam, for the purpose of raising and lowering the outer end thereof, but in such case the finger-beam was connected directly with the frame of the machine, and the frame had a limber tongue, so that the frame oscillated when the inner end of the finger-beam was raised and lowered. I am also aware that connecting-rods have been constructed with swivelboxes havin-g their pivots arranged crosswise of the length of the counecting-rod, in which arrangement the swivof them than those which are specified in the following claims; but

I claim as my invention- 1. The combination, substantially as above' set forth, of the finger-beam projecting laterally at one side of the main frame and stiffdraft tongue, and of both the running-wheels of the harvester, the hinged link connecting the finger-beam and Amain frame, and the hand-lever connected with the inner end of the finger-beam, for the purpose of turning up the outer end thereof upon the lower hinge-pivotl of the said link as an axis.

2. The combination, substantially as before set forth, of the finger-beam projecting laterally at one side of the mainy frame and stift'- draft tongue, and of both the running-wheels of the harvester, the link connecting the nger-beam and main frame, the hand-lever connected with the inner end of the fingerbealn, and the second lever upon the main frame.

3. The combination, substantially as before set forth, of the cutter-stock, the crank for driving the same, the oonnecting-rod, and the swivel journal-box of the connecting-rod, v

having its pivots arranged longitudinally of said connecting-rod.

Witness my hand this 29th day of May, A. D. 1875.
