To all whom it may U01/www: Like parts are indicated by the same letters i Be it known that LUHARLES F. GODDARD, in all the figures. a citizen of the United States, residing at A A are the rear supporting-wheels on the Chicago, in the .county of Cook and State of axle B, which is pivotally connected at B with 55 5 Illinois, have inventeda certain new and usethe'frame of the thrasher in` any desired manful Improvement in Thrashing-lvlachines, of ner. B2 is a short shaft at the forward end which the following is a specification. of the machine normally at right angles to a e.

A

Supported upon the standard C2 and projecting from the side of the thrasher is the bed plate or fraine E, upon which the driving portions of the engine are located. Journaled in the hangers E E depending from this 'bed-plate is the short shaft F, upon which is journaled one end of the pivot-block F, the other end of which carries the short shaft F2. On the shaft F is secured the gear F3, which may be either an internal gear, as shown in Fig. 6, or an external gear,as shown in Fig. 7. This shaft also carries the pinion F4, which is adapted to engage the gear F5 on the tractionwheel. The short shaft F2 carries at one end the pinion F6, adapted to engage the gear F2, and at the other the friction wheel or pulley F7. Rigidly secured to the pivot-block, preferably as indicated between the shafts F and F2, is the arm G, which carries the thu rnb-lever G', associated with thelocking-bar G2, which is adapted to be received into the teeth on the arc-shaped rack G3, whereby the arm, and therefore the pivot-block, may be locked in any desired position.

G4 is the. engine-shaft, which is suitably journaled and driven in the usual manner from the piston-rods G5 G5 of the engine. This shaft at one end carries the friction-wheel or` pulley G5.

G7 is a belt which surroundsthe pulleys or friction-wheels G6 and F7, and when stretched by their separation transmits power from one to the other.

On the opposite end of the shaft G4 is the gear-wheel H, meshing with the pinion H on the end of the thrashing-machine cylindershaft H2. The thrashing-cylinderis included within the casing l-l3 in the forward part of the thrashing-machine proper in the usual manner. In Fig. 5 I have shown a modification of these parts, which I will now describe.

H4 is a friction wheel or pulley on the engine-shaft G4, and which is substituted for the gear-wheel H. In like manner the friction wheel or pulley H5 is substituted on the cylinder-shaft H2 for the pinion H.

Il6 is an elbow-crank lever pvoted on the shaft H2 and carrying at the extremity of its short end the short shaft H7, upon which is the friction or pulley wheel H8.

H9 is a belt, which travels in the manner indicated about the three friction wheels or pulleys. The diameter and relation of the three wheels are such that when the friction wheel or pulley H8 is forced in between the other two, it tends to cramp or grip the belt against the two wheels, also to tighten the belt about them, also to support them on their journals against the action of the tightened belt. The long end of the lever H6 would be developed into a handle and provided with the usual locking device, for example, such as is associated with the handles G and D6.

J J are the engine-cylinders having the valve boxes and pipes J J.

K is the tank or carburetor containing the gasoline. L is the muffler; M, the water-tank. These three tanks are secured to the frame of the thrasher and over the axle toward the forward end of the machine, as indicated. water-tank is connected by the pipes -M'M2 with the cylinders of the gas-engine in the proper and usual manner. The carburetor is connected with the valve-cases by means of the pipe K', and the muffler is connected with the exhaust by means of the pipe L.

D20 is a broad heavysupporting-wheel used in lieu of traction-wheel when traction-wheel and gear are dispensed with.

A large number of the parts illustrated I have not lettered or specifically described, because they have to do with the operation of the thrasherorseparator or engine proper. My invention, however, relates more particularly to the other parts, such as I have fully described. It is, of course, understood that there may be great variation in the construction of these several features which I have illustrated and described, and some of them may be omitted with or without substitution of other parts, without perhaps materially affecting the operation of the remaining features. Moreover, in actual experienceit will be necessary to vary considerably all the general relations and proportions ol the several parts to adapt my improvements to the various kinds of separators. I do not, therefore, wish to be limited to the precise form of construction shown, nor to the use of all of the elements together.

The use and operation of my invention are as follows: I will first have reference to the means for guiding and leveling or settingthe device. It will be observed that I have provided a rear pivoted axle with aforward controlling mechanism including a hand-wheel, and bythe operation of that hand-wheel the device may be guided or directed in its progress. With separators generally, and particularly with separators of this class, and when my improvements are applied to them, it is important that there should be means for bringing the forward end of the machine to a level, and this I have accomplished by means of the crank-axle and controlling devices.

' The axle is normally in such position tha-t the supporting-wheel, which is smaller in diameter than the traction-wheel, is on a level with the traction-wheel, so that the machine at its forward end would rest level if the two wheels were upon a level surface. In this` condition the machine is ready for transportation. The irregularities in the road are taken up more or less by the actionvof the spring associated with the crank on the end of the axle. If, now, the machine is brought to rest in a position for use and it is found that the front end of the machine is not level, instead of resorting to the old expedient of digging The away from under one wheel and blocking up the other, I may simply by operating the handle D5 D( turn the axleso as to raise or lower' the smaller wheel thereof. Thus the forward end of the machine may be made to accommodate itself to irregularities of surface, and

the difficulties in setting the machine here-4 tofore encountered are largely avoided.

When my improvements are combined with traction-gear, it is desirable in machines of Vthis character to have .means wherebythe power from the engine may be readily transmitted to the traction-wheel to propel `the thrasher, or may be taken fromthe tractionwheel to bring the thrasher to rest. It is also evident that .it would be necessary to provide means whereby this power may be applied to rotate the traction-wheel in either-direction. Now these results I have .accomplished by means of the mechanism illustrated in Figs. 6, 7, 8, and 9. The controlling-arm G, when moved in one or the other direction, will evidently move the shaft F2 in an arc about the shaft F, and thus vary the distance between the shafts Gr4 and F2, or, in other words, vary the distance between the centers of the friction wheels or pulleys G6 F7. This is illustrated in Figs. 8 and 9, the wheels being shown in contact in Fig. 8 and separated in Fig. 9. When the wheels are brought together,las indicated in Fig. 8, the belt Gr7 will plainly be slackened, so as not to serve as a power-transmittingdevice; but the two friction-wheels will be brought together, so that from the wheel G6, which is driven from the engine-shaft, motion will be communicated to the wheel F7, as indicated by the arrow.

`Vlhen the two wheels are separated, as indicated in Fig. 9, farenough to tighten the belt, the` power will `be communicated from the p ulley Gr6 to the pulley F7., and thus the latter will be driven in the direction of the arrow and in a direction opposite tof/that produced when the device is used as illustrated in Fig. 8. Moreover, there is an intermediate position in which the twowheels operate neither as pul-A eys nor frictionwheel`s, andlin this position nopoweristransmitted. 'Assumingnowthat, as indicated, motion can be imparted in either direction to the wheel F7, or that i-t can be brought to rest, by referenjce to Figs. 6 and 7, we will see how the traction-wheel is controlled. The rotation of .the wheel F7 rotates the axle F2 and with it the gear F6. This gear or pinion engages the gear FSand thus drives the shaft F; but this shaft has in its inner end the pinion F4, which engages the gear F.5 on the tractionwvheel and thus puts the latter in motion. Piainly, therefore, by operating the handle Gr the traction-wheel may be disconnected from the engineshaft or maybe driven therefrom in either direction. Moreover, the transmission takes place byfric-` tional contact .rather thanl by gears. This frictioual contact method oftransmission :is highly important in many devices suchl as I have here suggested, and largely because of the high rate of speed at which the engine commonly runs. Thisis particularly important with gas-engines and the like, where there is no means for reversing the engine running continually in the same direction.

I have indicated in Fig. l and elsewhere the carburetor, muffler, and water-tank of an ordinary gas-engine outfit, and they are properly connected with the engine-as, for ex- `supplying devices or means for said engine,

and operating connections from the engine to the mechanism of the thrasher, and also,

.if desired, from Vthe engine to the traction or driving mechanism of the entire device. By

-this means no tender or associated device is required.

The device is self-contained, re quires but a single operator to move it from place to place or to operate it, and obviates the necessity of transportingfuel, water, and

'the like in any considerable quantities-such, `for example, as would be necessary in the case of an attempt to use a steam-engine.

It will also be observed that the engine and power-supplying devices which I employ are of i such nature that they may be associated together in close proximity to the thrasher and` grain to be worked upon. This would `not be the case with `engines operated :from

steam-boilers and the like.

I find that withengines operating atahigh rate of speed, as, for example, the gas'engine which I have suggested here as one form of engine to be used, it is desirable frequently to have africtional connection with the cylinder, and hence the mechanism of Fig. 5. By this mechanism the power is transmitted from the engine-shaft to the cylinder-shaft by means of a belt, and since this belt must be short and tight and since there would be a great tendency to bend or throw the parts out of position as a result of such tight belt, I have devised this improvement, wherein I employ the intermediate frictionwheel or pulley,.so situated and of such size that when forced between the ot her two it tightens the belt about them, cramps the belt upon their surfaces so ICO IIO

IZO

as to prevent slipping, and atthe same time engaging parts might slip sufficient to avoid the injury which otherwise might result to the operating parts of the machine. l

The power-transmitting device illustrated in Fig. 5 and the mechanism illustrated in Figs. 6, 7, S, and 9 it is obvious are capable of use in devices of this general character, where the other devices which go to make up the complete construction, or some of them, are omitted and many of them greatly changed. Indeed, either of these devices would be capable without material modification of use in any mechanism where the transmission of power in this general manner is desired and where in the application of power from one mechanism to another it is important to control the application so as to reverse or stop the driven part, and also where it is desirable to gradually vary the amount of the power transmitted.

Vhere the circumstances Linder which the machine is to be employed are such as to make the use of traction-gear unnecessary or undesirable, I prefer to substitute for such gear and wheel a plain supporting-wheel, of such size and shape as to serve properly to sustain the parts of the machine. Indeed, by the term traction-wheel I mean not only a traction-wheel proper associated with a traction-gear, but a wheel of wide tread or the like, so as to serve as such supporting-wheel.

My engine is preferably connected directly and non-elastically to the cylinder of the separator-that is, by means other than a belt or the like.

In a device of the general character here illustrated for many purposes it is desirable to have the whole apparatus supported upon a single common frame as distinguished from a frame consisting of sections hinged together or a frame consisting of sections which are coupledV together endwise. rlherefore I have limited certain claims to this peculiarity of construction, as it will be found that such construction leads to variations in the relations and connections of the parts. On the other hand, there are features of my invention which are not necessarily incorporated in a device where all the parts are supported upon one and the same common frame.l Therefore certain of my ciaims are not so limited.

I 'do not wish to be understood as considering my invention to consist in the precise device here shown, or in the complete self-contained thrashing-machine here illustrated, as it will be perfectly plain that certain features which I have here illustrated and sought to claim might be incorporated in a complete thrashing-machine, where the other features or elements greatly differ from those which I have exhibited.

As I prefer to construct my device and as I have therefore in some of the claims indicated, tlio cylinder of the separator preferably runs all the time, being so connected with the engine or engine-shaft as that it serves as a fly-wheel, and also so connected as that it runs all the time the engine is running.

The cylinder of a thrashing-machine, as they are commonly made, is not so heavy as the fly-wheel which would commonly be used with a gas-engine adapted to drive such cylinder, but the cylinder is commonly driven with a much higher rate of speed than would be necessary with a balance or fly wheel. Hence, as I have found by practical experience, the cylinder can be made to serve as a balance or iiy wheel.

Of course, as above suggested, some ot' the features of my invention could be utilized and incorporated in a machine in which the engine was provided with an additional or separate iiy-wheel or balance-wheel, should the latter be found necessary; and I do not wish to be limited in all my claims to a construction in which there is no balance or fly wheel except the cylinder. y
