SPECIFICATION forming part of Letters Patent No. 303,871, dated August 19. 1884.

Application filed h'ovember 13, 1883. (No model.)

To (055 whom it may concern:

Be it known that I, SAMUEL l). MADDIN, a citizen of the United States, and a resident of Miamisburg, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Harvesters, of which the following is a specification.

hilyinvention relates to that class of harvesters in which the frame supports a cutterbar in front of side wheels, and the draft-animals are in front of the bar; and my invention consists in constructing theapparatus, as fully described hereinafter, so as to facilitate the ad justment and driving of the cutters or the operations of the machine.

In the drawings, Figure 1 is ascctional elevation of my improved harvester. Fig. 2 is a side elevation, one of the wheels being removed. Fig. 3 is a sectional plan. Fig. 4 is a front elevation. Fig. 5 is a detached view showing the connection of the knife-bar and driving-arm.

The axle A and wheels 13 13 support the main frame, consisting mainly of slecves'a a, and an. arm, extending from the sleeve a. To this frame, composed of two parts hung independently to the axle, is jointed the swinging frame of the machine, consisting of side bars, (I d, a finger-bar, d, and connectingbar d, the side bar, 12', being hinged by a bolt, 6, to a hollow arm, j", connected to the sleeve a transversely thereto and above the same, the connecting-bar d extending over the hollow arm f, in the form of an arch. To the frame thus constructed, at the point where the side bar, d, and connecting-bar (r are united, is scoured a yoke, g, through which the sleevea passes, and which permits this end of the frame to be lifted up and down, the frame swinging upon the pivot-rod 0, but without the yoke losing its bearing upon the sleeve a. The cutter-bar is thus carried by a swinging pivoted frame, which, however, has constant positive connections and bearings upon the main frame of the machine. As it is desirable to lift the cutter-bar frame either enti rely or at one side or the other, I employ suitable devices for this purpose. For instance, at each side of the frame is pivoted, at a, a lever, D, which carry at the front the lead-wheels E, so that by lifting the inner end of either lever D, the leadwheel bearing upon the ground, the cutterframe will be raised at that side, while, by loweri ng the rear end of the lever, the cutter-frame will be depressed. Suitable appliances for lift ing the levers are employed. l have shown a shaft, F, provided with arms 7:, connected to the lovers D, and having a hand-lever, G, adjacent to the drivers seat 6, whereby the shaft may be turned, so as to lift or lower the ends of the levcrs'D. The shaft is preferably divided into two portions, one provided with the lever G and the other with a similar lever, G, so that either of the levers D may be moved and the corresponding side of the frame raised or lowered independently of the other. Each of the lovers D may be bent or carried inward from the pivot-point x at an acute angle with the cutterbar, so as to constitute a swathcr, and the usual shield, II, maybe pivoted to the frame at the point x. The levers G G are of course provided with the usual appliances for locking them into any position in which they are set. As there will be some play between the pivoted frame and the main frame, which is carried upon the axle, I connect the end of the finger-bar to the arm d by means of a link, If, as shown in Figs. 1 and 3.

By the construction thus described the operator with little exertion is enabled to raise or lower the cutter-bar throughout its entire length, or at either end to any desired extent,

,and to hold it in any position to which he ad justs it, and whatever the position of the bar may be the f ramc has positive bearings, which tend to prevent any destructive play or objec- .tionable noise.

To talzc the weight of a frame from the team, the pole I is so connected to the frame that the forward draft will tend to liftrather than depress the cutter-bar. Thus arms 0, extending from the sleeves a. a downward and to the .rear, constitute the bearings or braek ets J, secured to the pole, and any forward draft upon the latter acts in the direction of the arrow, Fig. 1, tending to lift the front of the cutter-frame, while any weight upon the forward end of said frame has no effect in increasing the downward pressure upon the team. Braces J strengthen thebrackets. Motion is communicated to the knife-bar K from abeveled wheel, L, having a ratchet at the edge, so as to be turned when the wheel B moves forward by the engagement of a pawhj. The

f, carrying at the front end a cranledisk', M.

the hole in the block q on the knife-bar, and

wheel L gears with the beveled wheel L upon I the shaft is, carried by the arm f, and carrying a pinion, Z, which gears with the pinions Z upon the shaft 0, extending through the arm The side bar, (1, is provided with arms supporting a rock-shaft, N, (Figs. 2 and 3,) arranged about midway between the level of the shaft'O and the ground, and having at the rear end an arm, m, connected to the disk by apitman, a, and at the forward end an arm, 12, which is connected to the knife-bar. The up per end of the arm m is about level with the shaft 0, the various bearings and connections thus described being such that the tilting of the swinging frame will not disturb the relative position of theknife-bardriving parts, so that the same will work effectively regardless of the movements of the said frame. In the lower end of the arm 1) is a hole .parallel to into the said holes extend the limbs of a yokeshaped link, 1', so that the movement of the arm P is easily communicated with but little loss to the knife-bar, while there is but little wear of the parts, and the connection is not liable to get out of order.

To prevent the link from becoming clogged by means of grass, stubble, &c., a flange, s, is extended from the knife-bar upward in front of the transverse portion of the link, as shown in Fig. 3.

In order to hold the k nife-bar closely to the finger-bar at its extreme end, where it is connected to the driving-arm, the said knife-bar is provided at the rear edge with a web, a, which extends beneath a lip or plate, 12, secured to the finger-bar, the knife-bar sliding freely beneath said lip, which holds it, however, firmly to its bed.

It will be obvious that other means may be employed than those described for driving the cutter-bar and for moving the operative parts of the machine and lifting the lead wheel levers. I therefore do not limit myselfto the same; but

I claim as my invention 1. In a harvester, the combination of the supporting-wheels, the main frame, a cutterbar frame pivoted at one side to the main frame, and provided with a yoke embracing the axle at the opposite side, levers pivot-ed to both sides of the cutter-bar frame, the lead-wheels carried by said levers, and appliances for adjusting said levers, substantially as set forth.

2. The combination of the supportingwheels, main frame, cutter-bar frame pivoted at one side to the main frame, and the driving-shaft 0, having its bearings in the main 3. The combination of the axle, the supporting-wheels, sleeves a a, cutter-bar frame pivoted to an extension of the sleeve to, and provided with a yoke through which the sleeve a extends, and a bar, 7), extending from the sleeve a and connected to the cutterbar, substantiall y as specified.

4. The combination of the main frame, the cutter-bar frame pivoted at one side, the levers D, pivoted to the cutter-bar frame, the lead-wheels carried by said levers, andlevers G G, and connections for operating the levers D independently of each other, substantially as set forth.

5. The combination of the main frame in two parts hung independently to the axle, a cutter-bar frame, projections extending from the main frame to the rear and downward, and a pole connected to said projections below and at the rear of the axle, for the purposes set forth.

6. In a harvester, the combination of the cutter-bar frame, the lead-wheels, and the le vers D, carrying said lead-wheels, and bent inward to constitute swath-boards, substantially as specified.

7 The combination of the main frame, cutter-bar frame pivoted at one side to the main 0 frame, levers D, wheels E, and independent levers G G, connected to the levers D, substantially as described.

8. The main frame in two independent parts hung to the axle, combined with a cutter-bar 5 frame pivoted to one of said parts at one side,

and connected by an arm to the other of said parts at the other side, substantially as speci- 9. The combination of the main frame and cutter-bar frame jointed together near one of the wheels by a rod, 6, parallel to the wheel,

a longitudinal driving-shaft, 0, arranged at 9ne side of the frame, parallel with and adjacent to the rod 6, and driven from .the adjacent supporting-wheel, the rock-shaft N, arranged on a plane midway between the shaft C and the ground, the knife-bar, and connections between the rock-shaft N, driving-shaft, and knife-bar, all substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
