CORN-HARVESTERQ SPECIFICATION formihg'part of Letters Patent No." 746,738, dated December 15, 1903. I

Application filed March 31, 1903. I

To all whom it mwy co ncern: Be it known that I, WILL IS'E. PELTON, a citizen of the United States, residing at Oklahoma 'city, inthe countyof Oklahoma and Territory of Oklahoma, have invented new and useful Corn-Harvester, of which the fol-' lowing is a specification. Y

This invention relates to that class of cornharvesters by means .of which the ears are, stripped or snapped from the stalks, which latter are left standing in the field; and it has for its object to provide a machine of this class which shall possess superior advantages in point of simplicity, durability, ease and certainty of operation, and general efficiency. V

With these ends in view my invention comprises a wheel-supported frame carrying a pair of snapping-rollers which are operated by power derived from one of the tractionwheels. p The devicefurther comprises an elevating device to receive the ears as theyare snapped from the stalks by the rollers and which serves; to carry them upward and to deposit them into a suitable receptacle, which may be the box' of a wagon driven alongside of the machine.

The invention further consists in an improved frame construction having side memhers connected by an arch and snapping-rollers journaled in said frame in connection with rotary means associated with therear ends of the side members of the frame, which while the undue expansion of the front ends of the side members of said frame.

My invention further 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 accompanying drawings, Figure lis a side elevation of a corn-harvester constructed in accordance with the principles of my invention. Fig. 2 is a rear elevation of the same. Fig. 3 is a horizontal sectionalview. Fig. at is a sectional detail view illustratin g one of the bearings for the lower ends of the snapping-rollers. Fig. 5 is a detailed side elevation showing a portion of the side Serial No. 150,4 6. (No man.)

of the machine opposite to that shown in Fig.

1. Fig. 6 is a sectional detail View on the line 6 6 in Fig. 1. I

Corresponding parts in the several figu res are designated by similar numerals of reference.

The frame of myimproved corn-harvester may be described as consisting of side pieces 1'2-, connected intermediate of their lengths by means of an upwardly-extending yoke or arch 3. Regarding the detailed construction of this frame I do not in any wise limit myself. Thus the side pieces may be made separate from or integral with the side menibers of the yoke or arch, and the construction of the latter does not necessarily involve the employment ofa separate top piece, such as shown at 4 in Fig. 2 of the drawings. The detailed construction of the frame may be modified to any extent within the scope of my invention.

The side members of the arch or yoke are separately designated 5 and 6, the side member 5 being adjacent to whatmay be properly termed the outer side of the machine. Said side member 5 is provided with a suitable bearing'for an axle 7, carrying a bull- .wheel S WhlGh is fixed upon said axle, from which motion is transmitted,as will be hereinafter described,,to the operating parts of the machine. The tongue 9 is supported upon the axle, with which it-is connected by means of a sleeve 10, in which said axle is revoluble, side motion of said sleeve being .prevented by means of set-collars 11 or other "suitable means.

12 designates a brace having a' sleeve 13, which is journaled upon the axle, .inwardmovement of said sleeve upon the axle being prevented by 'a set-collarl4.

The brace 12 is bolted or otherwise suitably attached to the frame of the machine, as will be readily understood. The drivers seat 15 is supported upon the seat-bar 16,whic h rises from the rear end of the tongue.

means of a chain with a sprocket-wheel 21 upon a shaft 22, which is journaled in suitable bearings near the upper endof the yoke 3. This shaft is provided with sprocketwheels 23 24, which are connected by means of chains 25 26 with sprocket-wheels 27 28, mounted upon stub-axles 29 30, which are suitably journaled in the side pieces 5. and 6 of the arch 3 near the lower end of said side pieces. The stubs 29 and 30 also carry spurgears 31 32, from which motion is transmitted to the stalk-guiding mechanism of the harvester, as will be hereinafter more fully set forth.

The side pieces 1 and 2 of the frame are extended forwardly and are provided at their front ends with shoes 33, which when the front end of the machine is dipped will pre- Vent said side pieces from digging into the ground. Said side pieces are also provided with upwardly and rearwardly inclined brackets or shelves 34, supported at their rear ends by means of braces 35, and upon these brackets or shelves are mounted endless carriers 36, having laterally extending fingers 37, that serve to engage the cornstalks and to carry them in a rearward direction toward the snapping-rollers. The endless carriers 36, which are constructed in the usual manner of suitably-joined links, a suitable-proportion of which are provided with the laterally-extending fingers 37, are mounted upon suitable supporting- pulleys 38 and 39 at the front and rear ends of the shelves, respectively, the shafts 40 of the pulleys 39 being extended downwardly and provided with bevel-gears 41. The brackets 35, which support the rear ends of the shelves 34, are provided with bearings for vertically-disposed shafts 42, the upper ends of which have bevelgears 43, meshing with the bevel-gears 41 upon the shafts 40 of the carriers. The lower ends of theshafts 42 are provided with bevel-gears 44, meshingwith' bevel-gears 45 upon transverse shafts 46, mounted in suitable bearings 47, provided upon the standards or supports 35. Said shafts 46 are also provided with sprocket-wheels 48, connected by chains 49 with sprocket-wheels 50 upon shafts 51, journaled in suitable bearings 52 upon the side pieces of the frame. The shafts 51 also carry pinions or spur-gears 53, meshing with the spur- gears 31 and 32 at the opposite sides of the machine and which have already been fully described, the intermeshing spur-gears 31 53 and 32 53 being provided for the purpose of reversing the motion, so as to cause the inclined carriers to operate in the proper direction.

I would have it understood that any other suitable means within the scope of my invention may be employed for the purpose of transmitting motion from the stub- axles 29 and 30 to the endless carriers 36.

The shaft 22, near the upper end of the frame, is provided with a depending yoke 55, having suitable bearings in which the upper ends of theshafts of the snapping-rollers 56 and 57 are journaled. The shaft of the outer snapping-roller 56 has a pinion 58, meshing with-a bevel-gear 59 upon the shaft 22, and both of the snapping-rollers are provided at their upper ends with intermeshing spurgears 60, causing them to be operated in opposite directions. The snapping-rollers are placed in a suitably-inclined position and their lower ends are made conical'or pointed, as will be seen at 61, in order to facilitate the entrance between them of the cornstalks the ears of which are to be gathered. The lower ends of the snapping-rollers or of the shafts 62 of said rollers are journaled in bearings 63, consisting of suitable recesses in elbowpieces 64, the horizontal arms of which are supported slidably in boxes 65, mounted upon the side pieces of the frame of the machine. Said boxes have recesses 66, containing springs 67, which exert an outward pressure upon the elbow-pieces, thus forcing the lower ends of the snapping-rollers in the direction of each other, but permitting them to expand sufficiently to admit of the passage between them of the stalks from which the ears are to be snapped. Other suitable means within the scope of my invention may be employed for so mounting the lower ends of the snapping-rollers as to permit them to expand against spring-pressure.

The frame of my improved machine, owing to its peculiar construction, is possessed of a degree of elasticity which unless counteracted would be liable to permit the front ends of the side pieces to expand, thus unduly separating the'snapping-rollers to an extent which might result in the passage between them of the ears which it is their function to remove from the stalks. To obviate this contingency, I provide each of the side piecesl and 2, near the rear ends of said side pieces, with vertical shafts 68 and 69, upon which are mounted a pair of disks or rollers 70 and 71, bearing or contacting against each other at their peripheries, so as to prevent the expansion of the front part of the frame. One of these disks, 70, has its rim or periphery provided with corrugations 72, the edges of which will contact with the rim of the disk 71, as shown, while said corrugations will admit of the passage between said disks of the stalks which have been deprived of their ears.

Supported by the sides of the frame a short distance in advance of the snapping-rollers are a pair of uprights 73, each carrying a plurality of spring-blades 74, which admit of the passage between them of the cornstalks and which serve when the ears are snapped from the stalks by the action of the snapping-rollers to cause to rebound such ears as are thrown in a forward direction by the action of the snapping-rollers and which without the presence of these rebounding-springs would be apt to land upon the ground. For the reception of the ears I provide at the lower end of the outer snapping-roller an inclined surface 75,consti- IIO ' imam the ears are conveyed to the lower endQo'f an elevator-trough 77, which is suitablysupport ed by the frame of the machine and which contains a suitably-constructed endless carrier 78, mounted upon pulleys at the upper andlower ends of the elevator-trough. The shaft 79, carrying the pulley at the upper end of the trough, also carries a sprocket-wheel 80, which is connected by a chain 81 with a sprocket-wheel 82 upon the outer end of the v V V V I V shaft 22,from which the said elevator is driven. The opposite end of said shaft carries a flywheel 83, which serves to overcome the momentary check caused by theears coming in contact with the snapping-rollers, The upper end of the discharge-trough is provided with a laterally-extending discharge-chute 84, which maybe of any desired length and which serves to convey the ears of corn to the place of deposit.

A spring connects the tongue 9 of the machine with a bracket extending from the adjacent side frame-piece 1, thus keeping the points of the side pieces of the frame normally supported above the ground. A bellcrank lever 86, which is pivotally connected with the tongue, has anupwardly-ext-ending operating-arm 87, provided with a spring-actuated dog or pawl 88, engaging a segmentrack 89, whereby the said lever may be retained in any position to which it may be adjusted. Thehorizontal arm of the bell-crank lever 86 is connected by means of a link 90 with the side bar 1, with which the spring 85 is also connected. The force of said lever may thus be exerted to depress the front ends or points of the side bars which constitute the gathering-arms against the tension of the said spring 85, as will be readily understood, thus enabling the side arms or gathering-arms to pick up down corn and cause it to be conveyed to the snapping-rollers.

A deflecting-board 90, suitably. supported 'upon the frame of the machine, is disposed adjacent to and slightlyabove the inner snapping-roller in order to prevent the ears of corn from droppingin an inward direction from said roller when it would naturally be deposited upon the ground and lost. By this deflecting-board the corn when snapped from the stalks is compelled to passiu an outward direction to the inclined side of the hopper provided for its reception and which guides it to the elevator.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of my invention will be readily understood The construction is simple and inexpensive, and by means of my improved machine the corn crop may be hararested much more expeditiouslyand economically than by hand. The importance of harvesting the corn crop quickly at the'time when it is in the proper condition is generally understood, and by my invention this result may be attained in a certain and'satisfactory manner.

I desire it to be understood that while I have herein shown and described a simple and preferred form of my invention I do not limit myself to the structural details herein set forth, inasmuch as many changes might be made with regard to the form, proportion, and relative arrangement of the parts. I reserve the right to any changes, alterations,
