HARVESTER.

SPECIFICATION forming part of Letters Patent No. 458,335, dated August 25, 1891.

Application filed October 16, 1890. Serial No. 368,372. (No model.)

To coZZ whom it may concern:

Be it known that I, NAAMAN L. DARLING, a citizen of the United States, residing at Benicia, Solano county, State of California, have invented an Improvement in Combined Traveling Harvesters; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to certain improvements in that class of machines known as traveling harvesters, in which the grain is out, thrashed, cleaned, and sacked ready for market at a single operation and while the machine is traveling about the field.

My invention consists in certain details of construction, which will be more fully explained by reference to the accompanying drawings, in which- Figure 1 is a plan view of the frame-work and such features of the upper part of the mechanism as are necessary for the explanation of my invention. Fig. 2 is a side elevation. Fig. 3 is a rear end View showing the weight-equalizer. Fig. at is an enlarged view showing the chain driving-gear and the mechanism for steering and raising and lowering the sickle. Fig. 5, Sheet 3, is an enlarged view of the sliding hinge is. Fig. 7-is an enlarged plan view of the drapers O and P, showing the hinge r. Fig. 8 is a detail.

In the construction of my apparatus I have shown three independent frames A, B, and O,

peculiarly hinged together, the frame A havinga pair of bearing-wheels D and serving to carry the engine from which power is derived to propel the machine and operate the various parts of the machinery. The frame B carries the thrashing, separating, and clean ing mechanism, and is connected with the frame A by hinges E, so that the two frames may have independent movements about the lines of these hinges. The frame B is situated upon the right-hand side of the engineframe A, and upon its right side is a bearingwheel D, which supports the outer side of the thrashing-machine frame, the inner side being supported from the engine-frame by means of the hinges E, before described.

The rear portion of the two frames A and B is supported by'the steering-wheels F, mounted upon an axle G, which is swiveled,

so as to turn about a vertical axis H. These wheels are turned by means of chains or ropes connected with opposite ends of the axle and leading forward to a drum, around which the ropes pass from opposite sides, and this drum is operated by a mechanism from the engine, so as to turn the steering-wheels in either one direction or the other, as will be hereinafter more fully described. The up right axis H is supported upona bar I, which extends forward from this point and has its forward end fitted to slide loosely upon a horizontal shaft J, which is fixed upon the frame A, as shown.

K is a bar having one end pivoted to the frame-work A, as shown at L. The bar is bent or curved downwardly from this pivotal point, extends along horizontally beneath the rear ends of the frames A and B, is again bent upwardly, and has the opposite end slotted, as shown at M, this slot being fitted to slide upon a pin N, fixed to the bar B.

To the central depressed portion of this bar the bar I is secured by clips 0, and by means of these clips it will be manifest that the bar I may be moved to either side, the front end sliding correspondingly upon the shaft J, until the bar I is at the desired point so as to equalize the weight of the two frames A and B upon the steeringwheels F, when the clamp 0 may be tightened upon the bar and thereafter remain permanently at that point. By this construction I am enabled to move the steering-wheels so as to regulate and equalize thew eight of the two frames upon thesewheels, and it will be manifest that when they are turned to one side or the other they will act to steer the machine to any desired point.

The engine and boiler are mounted upon the frame A. I have in the present case shown the engine as having two cylinders standing at right angles with each other, one horizontal and the other vertical, the axis of the cylinders intersecting with the driving-shaft, to which the connecting ods of'both are coupled, so that these engines acting at right angles upon the single-crank pin will always exert full power upon the driving-shaft and there will be no dead-center.

I prefer to communicate power for driving the traction-wheels from the driving-shaft P by means of a sprocket-wheel Q, fixed upon said shaft, and a chain R, passing from this sprocket-wheel to a larger sprocket-wheel S, upon the shaft of which is fixed another small sprocket-wheel T, and a chain U from this sprocket wheel passes around the large sprocket-wheel V, which is secured upon the side of the main bearing and driving wheel D. Upon the shaft P is fixed another sprocketwheel Z, around which passes a chain \V, and this chain drives the wheels X and Y.

a is a shaft, upon which is secured the drum a, and around this drum the chains 12 pass. These chains lead backward from this drum around a direction-pulley c and thence to the ends of the axle G of the steering-wheels, as previously described. The shaft a has one end mounted in a journal-box, which is carried upon the end of a lever d, and this lever is operated so as to swing the shaft from one side to the other. Upon this shaft is fixed a frictional pulley e, and this pulley may be thrown into contact with corresponding frictional drums ff, which are fixed upon the shafts of the wheels X and Y, and thus turned so as to turn the steering-drum in opposite directions when its controlling-wheelis thrown into contact with either one or the other of these frictional drums.

g is a drum upon which the rope or chain 71, which raises and lowers the header-frame, is coiled, and this drum has a similar frictionwheel 71, which is adapted to be thrown into contact with one of the frictional drums f by the action of a leverj similar to (Z.

Power to drive the thrashing and cleaning machinery is derived from a counter-shaft which receives power from the main engineshaft. This counter-shaft extends across from the frame A to the frame B and has an inter mediate universal joint in line with the hinges E, so that it is free to bend at this point and accommodate itself to the varying movements of the two frames A and B as the machine passes over irregularities on the surface of the land.

The frame 0 extends entirely across the front of the frames A and B and it is hinged to the frame B by a hinge 70. It is hinged to the frame A by a hinge 79. This hinge consists of a head bored soas to slide upon the horizontal rod or shaft Z, the head being allowed to slide between the ends of this rod to accommodate the movements of the two frames 'A and B about their intermediate hinges E. As it will be manifest that sometimes these frames will be bent at such an angle with each other that a line drawn be tween their outer sides would form the longest side of an obtuse-angled triangle, and as this would be shorter than a" straightdine drawn between the same points when the frames were level or in line with each other, it will be manifest that these hinges 7e and it must be so constructed as to compensate for this change of distance, and by allowing the head k to slide upon the shaft Z, which connects it with the header-frame 0, this compensation is effected.

The head Z0 has a shaft 79, journaled horizontally upon the frame A, as shown, and this shaft turns slightly in its j ournal-boxes to accommodate itself to the varying movements above described, this being necessary on account of the fitting of the head or hinge to the shaft Z, which is at right angles with the shaft k This construction allows perfect freedom of motion at this point without any binding or cramping, and the other hinge 7; may thus be made of the ordinary form without any compensating device.

The sickle-bar and sickle m extend entirely across the front of the machine. Tran sverselymoving drapers n deliver the cut straw and grain upon a draper 0, which travels back wardly from the front of the machine, thus carrying all the grain which is received from the drapers n, delivering from the sides, and also the grain which falls directly upon it from the sickle m. This draper 0 delivers upon a self-feeder p, hinged to the frame B, and this in turn delivers the grain to the thrashingcylinder q.

As the header-frame O has a movement to elevate and depress it about the hinges 7t, and there is also another movement given it by reason of the hinges between the frames A and B, it will be manifest that some adj ustment mustbe made between the draper 0 and the self-feederp. This is effected by means of the hinge 0', by which the one side of the frame 0 is hinged to the corresponding side of the frame of the self-feeder p. The opposite sides of these two frames are not connected, and it will be seen from this construction that when the frames A and B are tilted with relation to each other so that the outer sides are above the ends adjacent to the joint connection between them the movement of the hinge 7t, before described, will take place. At the same time the tendency of the side of the draper-frame 0, which is connected by the hinge 0', will be to move about the hinge k as a center while the frames A and B are turning about the hinges E. This action is allowed to take place without binding or cramping by hinging the frame at r, while the opposite side is left free, and this side of the draper 0 and the side of the selffeeder p are thus allowed to move about their diiferent centers without cramping. The wire rope or cord 71, which raises and lowers the header, is, as before described, wound upon a drum g, and this rope forks or separates into two before it reaches the front end of the machine, and the two parts there pass around guide-pulleys s and are directed, respectively, to the outer sides of the headerframe 0, at which point they pass again around guide-pulleys, and thence over pulleys 6 upon the upper ends of the supportingtimbers u, in which these pulleys are journaled, thence the ropes lead down to the header-frame, to which they are attached, as

shown, and when they are drawn up or relaxed the header-frame will be correspondingly raised or depressed. naled in the ends of the supporting-aims to, which arms are pivoted in the posts as and ex- .tend backward through the slotted guides y upon the posts 2. The rear ends of the levers w are connected with the stationary standards a by the links 2. Now the action of these links and the levers w, fulcrumed in the posts a", will be as follows: By reason of the two different f nlcrum-points, about which the parts move, it will be seen that when the header-frame O is depressed about the hinges 7c the front end will also be depressed, carrying with it the reel and the rear of the supporting-arms 20, but by reason of the links 2, connecting the rear ends of these arms with the stationary standards it, which are fixed to the main frame, the reel will be depressed as the front of the header is depressed and will travel nearer to the sickle, thus enabling it to sweep the short grain more thoroughly upon the draper and prevent its being scattered and lost. \Vhen the header is raised so that its front end is higher, the reverse of this action takes place, and the reel is correspondingly raised from the front of the machine. This connection being automatic with the raising and depressing of the headerframe, it will be manifest that no attention need be paid to it, but that itwill always operate as above described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a traveling harvester, the frames A and B, hinged together and standing side by side, having the engine mounted upon one frame, the thrashing and cleaning mechanism upon the other, a header-frame hinged to the front of the two, a pair of bearing-wheels beneath the engine-frame, a single wheel supportin'g the side of the thrashing mechanism which is opposite to the hinges, and a steering wheel or wheels adapted to support the rear of the two connected frames jointly and movable about a vertical axis, so as to steer said mechanism, substantially as herein described.
