TRAVELING HARVESTER.

SPECIFICATION forming part of Letters Patent No. 483,449, dated September 27, 1892.

Application filed April 25, 1892. Serial No. 430,606. (No model.)

T a/ZZ whom, it may concern:

Be it known that I, BENJAMIN HOLT, a citizen of the United States, residing at Stockton, San Joaquin county, State of California, have invented an Improvement in Traveling Harvesters; and I hereby declare the following to "be a full, clear, and exact description of the Same.

i Wheels in a vertical position at all times, whatever niay be the inclination or variation ot' inclination of the ground upon which the machine is working.

It also consists in details of construction by which this is carried out.

Referring to the accompanying drawings for a more complete explanation of my inl. Fig. 4 is a detail plan view of vention, Figure l is a plan view of my harvester. Fig. 2 is an elevation of the. same,

,the side timber C being removed. Fig. 3 is an end section of the same on line y y ot' Fig. the raising clutch mechanism. l

The object of my invention is to enable a traveling harvester and thrasher to be used upon side hills of any description andmain- Y tain the frame of the thrasher and cleaner at .l so much of the outlines ot' the well-known traveling harvester, thrasher, and cleaner as will enable my present invention and its connection therewith to be clearly understood. I have purposely left out all unnecessary wheels, belts, and gears by which the various t portions of the machinery within are driven,

but which are of common knowledge to every one familiar with this class of machinery.

harvest-entraine, having the transverse timbers B fixed across them and extending beyond them upon each side in front of and be-` hind the bearing wheels. Upon the outer ends of these transverse-timbers are the side timbers C, which, with the transverse timbers, inclose the space within which the main bearing-wheels D travel. These wheels are ordinarily journaled across this frame upon short independent shafts; but in the present case I have shown a supplemental frame E, which is sufficiently smaller than the space included lbetween the timbers A, C, and B to allow this i frame to move freely in the space. The wheels D have the independent shafts F, journaled` in boxes G upon the frame-timbersE which, as

`before described, are independent of the timbers A and C. At one end the timbers E are hinged to the transverse timbers B of the main frame. In the present case I have shown these hinges at the rear ot the bearingwheels for the purpose of placing the operating mechanism near the front and within reach of the driver, as the apparatus to which the device is here shown attached is of that class in which the machine is hauled by a team of horses or traction-engine or other motor attached to the front.

It will be manifest that if the apparatus be Ydriven by power applied at the rear, as in .the case of some harvesters, a different arrangement of details would be necessary; but the main features of the construction would be retained-that is, the hinging of the wheel` ytrames to the main frame, so that the wheels `could be raised or depressed independently of `each other.

Various devices may be employed to raise frame and journaled in bracket-boxes beneath the main frame A. The chains II extend from the Winding-drums up to the pro jecting ends of stout brackets J, which are ixed upon the swinging wheel-frames. The `chains connecting with the brackets of the swing-frame upon one side of the machine are A are the longitudinal base-timbers of the IOO coiled about their respective drums in one direction, while the chains of the opposite side are coiled about their drums from the opposite direction. It will thus be seen that when the shaft K is turned in one direction the chains upon one side of the machine will be wound up, thus drawing the ends of the swing-frames down below the level of the main frame, while the chains at the opposite side willfbe correspondingly unwound and the swing-frame with which they connectwill be allowed to rise in. proportion as the frame on the opposite side is depressed. The effect of this is plainly shown' in Fig.'3, in which the relative positions of the two wheel-frames serve to retain the main frame A and the operative parts of the machine in a level position. In order to rotate the shaft K, by which these movements are accomplished, I have shown a transverse shaft N, extending in the present case just above the shaft K and having upon it the worm or screw O, which meshes directly with a gear-wheel P, fixed upon the shaft K, so that when the worm 0 is turned in either direction it will act through the gear to rotate the shaft K either one way or the other. j

Upon the end of the shaft N is a beveled gear Q, and just in front of it is journaled a shaft R, having upon it beveled pinion sS and S', which engage with. opposite sides of the gear Q. These pinions are. loose upon the shaft R and ordinarily receive no motion from it, the shaft R being free to turn within them; but either one of the pinions is caused to engage so as to turn the gear-wheel Q by means of a clutch-sleeve T, which slides upon a feather on the shaft R intermediate between the pinions S and S. The shaft R being rotated in one direction all the time, it will be seen that when the clutch T is moved to engage one of the pinions S it will revolve the gear Q, shaft N, and Worm O in one direction and through it will turn the gear-wheel P and the shaft K so as to raise the hinged wheel-frame upon one side and depress the wheel-frame upon the opposite side. By reversing the clutch T and causing it to engage with the opposite pinion S the movement of the parts in the opposite direction will be produced. The shaft R, the end of the shaft N, and the bevel-gears Q, S, and S are supported in an iron bracket bolted to the main frame B. vThe shaft R has a sprocket-wheel U, and a chain from this sprocket-wheel passes around a sprocket-wheel V, xed upon the outer end of the driving-shaft of the selffeeder, which supplies unthrashed straw to the thrashingcylinder, and also over the sprocket-wheel V at the opposite end of the feeder. As this self-feeder is always in motion when the machine is traveling, it will be seen that the shaft R will also be driven with it, and it will onlyT be necessary to operate the clutch T by a suitable mechanism to engage either of the pinions S and S', and thus raise or lower either side of the machine.

The connection to drive the mechanism may, however, be made With any convenient part of the machine.

Theoperating mechanism in the present case consists Vof a clutch-lever W, the forked ends 0f which engage the groove or channel in the clutch T. at Y, and a rearward extension W is connected by a link Z with a lever a, fulcrumed at b upon the top of the case containing the self-feeder. This lever a extends forward to a point within easy reach of the operator and there engages a rack c, by which it maybe held either in acentral position, in which the clutch T is disengaged from both the pinions S and S', or it may be held at one side or'the otherto engage one or the other of the pinions with the clutch. In this manner it is easy to apply the power to raise or depress either of'the Wheelframes with reference to the main frame. In the present case I have shown the hinges t', by which the wheel-frames E lare connected with the transverse timbers B, at approximately a level with the wheel-frame E uponA the right side of the machine; but upon the left side the hinge is shown as elevated above the frame E and connected with it bya stout strap-iron j. The object of this is to bring the hinge approximately into line between the wheel-shaftF and the shaft k, upon which is fixed the sprocket-wheel, to which power is communicated by the chain from the sprocket-wheel upon the main bearing-wheel D on that side. By this construction the chain will be maintained sufficiently tautfor all practical purposes whether the wheel-frame be raised or depressed about its hinge, the chain slackening a little when it is raised or depressed to the extreme distance, but not sufficiently to interfere with the operation of the machine.

In order to maintain the proper connection between the header-frame, which is hinged to the right side of the thrashing machine frame, the rear timber m of this frame is connected by a loose or rolling hinge-joint n with the rear end of the outer frame-timber O upon This clutch-lever W is fulcrumed IOC IIO

that side, while the front header-frame tim- I ber 0 is connected with a pin p upon the outer wheel-frame timber E upon that side, as is plainly shown in Figs. -l and 3. By this construction it will be seen that the front timber o of the header-frame, being connected with the wheel-frame E, will always remain in the same relation with the surface of the ground, while the rear timber m, being connected with the main frame of the machine,

will be raised or depressed with relation tov from this construction of my device` that no matter how much the wheels may be raised or depressed with relation to each other they always stand in a vertical plane, orwhat is termed upon a plumb-spoke, as shown in Fig. 3, and, the main frame being always mainalthough it works upon an incline as great as forty-five degrees.

It will be understood that in harvesting ,l grain upon side hills the machine will always o move in an approximately-horizontal line along the face of the hill and at right angles with the inclination thereef.

The `gearing and mechanism herein described have been tested and found to work "ina satisfactory manner; but it will be obvious that the adjustable wheel-frames lnay be` operated by many different mechanical contrivances which will suggest themselves to a mechanic, the object being in any case to maintain the main frame in an approximately-level position by the relative movements of the independently-movable wheels.

I-Iaving thus described my invention, what I claim as new, and desire to secure by Letters l. The hinged frames within the m aiu frame ofthe machine and carrying the main supporting-wheels, and mechanism connecting said frames to move one of them simultaneously with and in a vertical direction opposite to the other wheel-frame, whereby the `said hinged frames may be adjusted to the surface of the ground without affecting the .l normal horizontal position of the main frame.
