CORN-HARVESTER.

SPECIFICATION forming part of Letters Patent No. 464,57 3, dated December 8, 1891. Application filed June 9, 1891. Serial No. 395 ,692. (No model.)

To all whom it may concern.-

Be it known that I, MILES K. LEWIS, a citizen of the United States, residing at Hastings, in the county of Adams and State of Nebraska,have invented a new and useful Corn- Harvester, of which the following is a specification.

This invention relates to corn-harvesters; and it has for its object to provide a machine of this class which shall possess superior advantages in point of simplicity, durability, and general efficiency.

WVith these ends in view the invention consists in the improved construction, arrangement, and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, Figure 1 is a plan View of a corn-harvester constructed in accordance with my invention Fig. 2 is a front view of the same. Fig. 3 is a side elevation. Fig. 4 is a sectional rear elevation taken on the line 4 4 in Fig. 3. Fig. 5 isa perspective detail view of one of the reels and the cam for operating; the arms of the same.

Like numerals of reference indicate like parts in all the figures.

1 designates the axle of the machine having the transporting-wheel 2 2, the rims of which are corrugated in the usual manner to prevent slipping. Suitably secured to the axle are the frame-bars 3 3, which are extended rearwardly, as shown. To one of said bars is hinged the gate-bar 4, to the under side of which is swiveled the caster-wheel 5, which supports the rear end of the frame. A seat 6 for the driver is supported upon the said gate-bar, to which is also attached the whiffletree 7 for the attachment of the draft. Three horses are ordinarily employed, one walking between and one on each side of the frame-bars 3 3. The middle horse may be admitted by opening the gate-bar 4, and the latter also serves to connect and re-enforce the frame-bars 3 3.

8 designates a transverse shaft, which is journaled in the frame-bars 3 a suitable distance in rear of the axle. This shaft, which I call the main shaft of the machine, is provided with sprocket-wheels 9 9, provided on their outer sides with clutch memberslO. The sprocket-wheels 9 are mounted loosely upon the main shaft 8 and are confined between the collars 11 and clutch members 12, which latter are feathered upon the shaft and forced in the direction of the sprocket-wheels 9 by coiled springs 13. The clutch members 12 are annularly grooved and are engaged by' hand-levers 14, by means of which they may, when desired, be thrown out of engagement with the sprocket wheels 9. By this mechanism motion is transmitted to the main shaft 8 from the transporting-wheels, which latter are provided on their inner sides with sprocket-wheels 15, connected with the sprocket-wheels 9 by means of chains 16. When the machine travels in a forward direction, the main shaft 8 will be rotated. WVhen the machine is being backed or turned, both of the sprocket-wheels 9, or one of them, as the case may be, will slip idly over the teeth of the adjoining clutch; and when the machine is to be transported over the road or from one field to another both of the clutches may be thrown out of engagement by means of the hand-levers 14.

17 designates an auxiliary frame, which is provided at its rear end with brackets 18, mounted upon the main shaft 8 near the ends of the latter. At the front end of the frame 17 is the front elevator-frame 19, mounted pivotally upon a transverse shaft 20. The rear end of said elevator-frame is supported by uprights or brackets 21, rising from the side beams of the auxiliary frame 17, as shown.

The main shaft 8 carries a bevel-gear 22, meshing with a pinion 23 upon the rear end of a shaft 24, which is mounted in suitable bearings upon the frame 17. Shaft 24 is provided near its front end with a crank 25, which is connected by a pitman 26 with one end of a lever 27, which is pivoted at 28, and the opposite end of which is suitably connected with the transversely-reciprocating cutter-bar 29, which is mounted in the usual manner in the finger-bar 30 of the cutting apparatus. The latter, which is of ordinary construction, may be suitably mounted upon the front end of the frame 17. At each end of said cutting apparatus is stepped or journaled a vertical reel-shaft 31. Additional bearings for the said reel-shafts may be formed in arms or brackets 32, extending forwardly from the uprights 21, which support the rear end of the front elevator-frame. The reel-shafts 31 are provided near their upper ends with heads 33 in recesses 33', in which are pivotally mounted the radial arms 34, which are supported in a horizontal position by means of the shoulders 35 striking the bottoms of said recesses, but which are capable of swinging in an upward direction when the said arms come in contact with the incline or cam-shaped tracks 86, which are suitably secured to the sides of the brackets 32. These cam-shaped tracks extend a little more than half-way around directl y over the elevator-tram e, and they serve to guide the afms of the reels out of engagem entwith the cornstalks, which, by the action of the said reels, are forced into engagement with the cutting apparatus. The reel-shafts 31 are provided near their lower ends with drums or disks 37, having radially-extending spikes 38, which serve to guide the lower ends of the cornstalks into engagement with the cutting apparatus and away from the ends or corners of the same.

39 designates the front elevator or endless carrier, which is mou nted upon suitable rollers or cylinders upon the shaft 20 at the lower end of the elevator-frame, and upon a shaft 40 at the upper end of said frame. Near the upper end of said frames are mounted brackets 41, having sprocket-wheels 42, which are connected by chains 43 with sprocket-wheels 44 upon the main shaft 8. The ends of the upper elevator-shaft 40 are also provided with sprocket-wheels 45, which are engaged by the front sides of the chains 43, thus transmitting motion in the proper direction to the endless carrier or elevator 39. The lower elevatorshaft 20 is provided with pinions 46, meshing with spur-wheels 47 upon a transverse shaft 48, journaled in the sides of the frame between the lower ends of the reel-shafts and the shaft 20. The said transverse shaft 48 is provided with bevel-gears 49, meshing with bevel-gears 50 upon the lower ends of the reel-shafts 31, to which motion is in this manner transmitted.

The frame-bars 3 support the cross-bar 51, upon which ashaft 52 is mounted in suitable bearings. Said shaft has a sprocket-wheel 53, which is connected by a chain 54 with a sprocket-wheel 55 upon the main shaft 8, from which motion is thus transmitted to the shaft 52. The side bars 3 3 of the frame are provided with sockets 56, in which are moun ted the uprights 57, which are interchangeable from one side of the machine to the other. At the upper ends of said uprights is pivoted an elevatonframe 5S, whichis provided at its upper and lower ends with the

shafts

59 and 60, both of which have sprocket-wheels 61, supporting the endless carrier, which is composed of endless chains 62, having upwardly and outwardly extending teeth or prongs 63, projecting above the bottom boards 64 of the elevator-frame. The lower end of the elevator-frame 58 is adapted to rest upon the sill or frame beam 3 opposite to that which supports the uprights 57. The latter being connected with the elevator-frame at a point nearer its upper than its lower end, the sa d elevator-frame will readily be supported in position for operation. The lowershaft of the elevator-frame is provided with a bevelgear 65, which is adapted to engage either one of the bevel-gears 66, which are mounted upon the transverse shaft 52 near the ends of the latter. It will be seen that by this arrangement the elevator 58 may be readily ad justed, so as to discharge the corn at either side of the machine by simply changing the uprights 57 from one side of the frame to the other and at the same time reversing the position of the elevator-frame, as will be seen in dotted lines in Fig. 4 of the drawings.

To the frontend of the auxiliary frame 17 are attached chains 67, which are connected adj ustably with hooks 68 upon the rock-shaft 69, which isjournaled in suitable bearings at the front ends of the sills or frame-bars 3. The rock-shaft 69 has an upwardly-extending arm 70, which is connected by a rod 71 or other suitable connection with a handlever 72 suitably pivoted to the frame of the machine within reach of the driver, who is thus enabled to raise or lower the front end of the auxiliary frame carrying the cutting apparatus, the reels, and the front elevatorframe. The lever 72 is to be provided with a spring-catch 7 3, engaging a rack-bar 74 for the purpose of retaining it in any position to which it may be adjusted.

The operation of this invention will be readily understood from the foregoing description, taken in connection with the drawings hereto annexed. v

While the machine is principally intended for harvesting corn, it may be used for cutting any kind of grain that may be desired. The machine is pushed over the field by the horses, which are hitched at the rear end of the frame, and the stands of corn are brought into contact with the cutting apparatus by the revolving reels. Then the cornstalks are severed, they drop upon the carrier 39 and are carried by the latter in an upward and rearward direction until they drop upon the transversely-arranged carrier, the frame 58 of which may be arranged to discharge the corn at either side of the machine. An apron or guide 7 2, suitably arranged at the lower end of the elevator-frame 58, prevents the corn from dropping olf the transverse carrier. The

ground in bunches for shocking, or it may be discharged into a wagon, which may be driven alongside of the harvester. When the machine is turned at the end of the field, the car rier-frame 58 is reversed, so as to discharge the corn in an outward direction from the standing corn.

The general construction of my improved corn may be discharged directly upon the corn-harvester is simple and inexpensive, and the draft being attached in rear of the harvester-frame, the progress of the horses will not be impeded by the standing corn. It will be observed that the corn, as soon as cut, is carried directly in a rearward direction by the carrier 39, and not to one side, as is customary in this class of harvesters. By this arrangement the cornstalks are kept in proper shape, and Width of the machine is economized.

Having thus described my'invention, what I claim is 1. In a machine of the class described, the combination of the main frame having the transverse main shaft,brackets mountedupon the latter and having the forwardly-extending auxiliary frame carrying the cutting apparatus, the front elevator-frame connected with said forwardly-extending frame by the lower elevator-shaft, the uprights .npon the auxiliary frame supporting said elevator frame, the brackets extending forwardly from said uprights, the reel-shafts journaled in said brackets and in suitable steps at the ends of the cutting apparatus, the endless carrier, and suitable mechanism for operating the latter and the reels, substantially as set forth.
