LINUS G. STEWART, OF SAWYER, NEBRASKA.

CORN-HARVESTER.

SPECIFICATION forming part of Letters Patent No. 511,554, dated December 26, 1893.

I Application filed April 13, 1893. fierial No. 470.209. (N0 model.)

To all whom it may concern.-

Be it known that I, Luvus G. STEWART, of Sawyer, in the county of Fillmore and State of Nebraska, have invented a new and Improved Corn-Harvester, of which the following is a full, clear, and exact description.

My invention relates to an improvement in corn harvesters, and it has for its object to provide a means whereby when the machine is drawn over a field of standing corn the ears will be expeditiously and conveniently removed from the stalks, delivered to a carrying belt and from the carrying belt be delivered to a conveyer or elevator, whereby the ears of corn may be loaded in a vehicle following the harvester, or whereby the ears ofcorn may be distributed inro'ws upon the ground.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth and pointed out in the claims.

Reference is to be had to the accompanying drawings forminga part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure l is a plan view of the machine a portion of the frame being in horizontal section. Fig. 2 is a side elevation of the machine, the upper portion of the frame and the elevator being broken away. Fig. 3 is a vertical transverse section taken practically on the line 3-3 of Fig. 1. Fig.4 is a front elevation of the machine. Fig. '5 is a partial side elevatiou taken at the rear portion of the machine, or that portion where the elevator is located, the elevator being in transverse section. Fig. 6 is a section taken on the line 06 of Fig. 5, illustrating the location of the gearing at both sides ofthe machine, and particularly the connection between the gearing for driving the elevator and the gearing for driving the endless carrying belt of the machine. Fig. 7 is a section taken on the line 7-7 of Fig. 5, showing the gearing in Fig. 6 in plan view. Fig. 8 is a detail view of the cutting sickle; and Fig. 9 is a broken top view, partly in section, of the sickle and the-take-up connected therewith.

In carrying out the invention the frame of the machine may be of different shapes, but

ordinarily the front of the machine consists of four

uprights

10, 11, 12 and 13, arranged in pairs, and corresponding

uprights

14, 15, 16 and 17, located at the back of the machine. The uprights are connected at their ends by a cross sill 18, a second sill 19, being located between the centers of the rear uprights and their upper ends. The front and rear standards are likewise connected by side beams 21, as shown in Fig. 2, and diagonal side beams 23. The diagonal beams at their forward ends are attached to a cross beam 25, uniting the front standards or uprights; the beam 25, being preferably secured vto the front uprights and the side beams 21, are

secured upon the rear cross beam 19, one near each upright, and are likewise secured upon the corresponding front cross beam 25. I desire it to be understood that all the cross beams are adjustably connected with the uprights in order that the two sets of uprights at the right and the mechanism carried thereby, and the two sets of cross beams at the left, may be adjusted to or from each other so as to leave more or less space between the central uprights; or if in practice it is found desirable the cross bars will be made to stop ateach of the intermediate uprights front and rear,'not crossing the space between the said intermediate uprights. In order to provide for this adjustment the two sections of the frame designated by the reference letters S and S, are connected by screws S which are passed through the front and rear

intermediate uprights

14 and 12 and 15 and 16, the said screw being provided with a jam nut s and a lock nut 8', located at opposite sides of each of the said central or intermediate uprights. The front set of standards or uprights is connected with the rear set of standards at their bottom by sills 26, which sills extend from the bottom portions of the front standards diagonally upward and rearward to a connection with the rear standards between their lower ends and the attachment of the upper diagonal beams 23; and further in the construction of the frame the rear standards or uprights project farther downward than the forward standards, as shown in Fig. 2.

Between theleft-handlowersidebeam26and the corresponding beam connecting the intermediate and rear standards of the left-hand set the space is open. The opposing intermediate front and rear uprights of the left-hand set are connected by quite a wide division board 29, the board being shown in Figs. 2

' and 3. This board also assumesan upwardly and rearwardly diagonal position, and is at an elevation above the sills 26, and it serves to force the stalks to incline in an opposite direction, that is, in direction of the righthand side of the machine. Each set of forward standards is connected at its lower end by a sill 30, and an A-frame 31, is pivotally connected with the front intermediate cross bar or beam 25 of the frame, as shown in Figs. 1, 2 and 4; and back of the upper end of the A-frame an equalizing bar 32, is pivoted upon the same fulcrum as the A-frame.

A vertical shaft 33, is carried downward through the side lower sills at their forward ends. One of the shafts, that at the left-hand side of the machine, extends some distance above the sill 26, and is provided with a handle 34, capable of being grasped by the hands of the driver, or pressed by his foot, as at the back of this shaft the drivers seat 35, is located, supported upon the left-hand side beam 26. Each shaft 33, extends below the lower face of the sill through which it passes, and is firmly secured at its lower end to a sleeve 36, and from this sleeve an outwardly extending stud axle 37, is projected, and upon each of these stud axles a small supporting wheel 38, is loosely mounted. In fact the axles of these wheels are properly angle axles, and their upright members turn in the frame of the machine.

The wheels 38, may be termed caster wheels as through the medium of these wheels the machine is to be guided, and both of the wheels are adapted to be turned simultaneously either to the right or to the left as oocasion may demand, by operating the handle bar 34 of the left-hand axle 33. Thus the concerted action of the two forward or caster wheels is accomplished through the medium of the A-frame, and in the following manner: Upon the horizontal member of each axle or shaft 33 the inner ends of a yoke 39, are loosely mounted, and the yokes extend one member at each side of each forward wheel. The said yokes are given preferably a slight upward inclination, and are carried at the same time forward. The members of the yokes at their upward or forward ends are made to closely approach each other, and are carried vertically upward; and in the upwardly-curved end of each yoke a guide wheel 40, is journaled, while a cross bar 41, is mounted upon the members of each yoke between the wheels and the forward ends of the yoke; and the lower extremities of the A- frame 31, are fitted in or secured to the yoke cross bars 41 in any suitable or approved manner. Thus when the left-hand axle or shaft 33, is turned a like movement will be imparted to the opposite axle through the medium of the A-frame.

The yokes are supported in their slightly upwardly inclined position by means of stay rods 42, connected with the yokes near their forward ends, and with the outerof the front set of standards, as shown in Figs. 1, 2 and 4. A link 43, is pivotally attached to each end of the equalizing bar 32, and each link 43, has connected with it a length of chain 44, and the chain is made to pass downward over guide rollers 45, located upon the outer front standards of the frame, and at the opposite or forward ends of the chains 44 a second link 46, is attached, and the links 46, are passed through the upwardly inclined ends of the yoke and are made to engage with the rollers 40, the whifiletrees 47, being attached to these lower links. Thus the equalizing bar 32 is located out of the way of the corn.

Fingers 48, are attached to the intermediate of the front standards of the frame, the fingers being made of any suitable or approved material; and these fingers 43, extendforwardlyanddownwardly, their forward extremities being flared or curved in opposite directions; and the machine is to be so driven that the standing corn will enter the space between the fingers 48 and be guided to the central open portion of the machine. The fingers are ordinarily provided with uprightly extending guards 49 adapted to project over the lower ends of the rollers 50, to be described presently.

In order to insure the upper as well as the lower portion of the corn stalks being guided into the central portion of the machine, rollers 50, are located at each side of the fingers, being journaled at their lower ends in bearings located upon the fingers, as shown, or upon the guards near the flaring outer ends of the fingers (this modification is not shown in the drawings); and the upper ends of the rollers are journaled in bearings 5O located upon the outer faces of the intermediate standards 11 and 12 of the frame, as is best shown in Fig. 4, and a steel plate or guard 50", is made to fill the space between the rollers, the fingers 48 and the inner edges of the intermediate front standards 11 and 12, as shown best in IIO Fig. 4; and these guide plates are so placed in order to prevent loose ears of corn from becoming lost. Opposite the lower edge of the division board 29 a guide board 51, is located, which guide board follows the inclination of the division board and connects the front and rear intermediate standards of the right-hand set. This board is shown in plan view in Fig. 1, and in section in Fig. 3. The upper face of the guide board is beveled, the inclination being downward in direction of the space between the inner and outerstandards of the right-hand set, and the object of this guide board is to direct the ears of corn, when severed from the stalk by the machine, upon the endless apron or carrying belt 52, which side of the machine.

endless carrying belt practically fills the space between the standards of the right-hand set,

, as shown in Figs. 1, 3 and 4. The outer edge of the endless belt may be provided with any suitable or approved form of guard to prevent the ears of corn from falling through at the This endless carrying belt is passed over a drum 53, located at the rear extremity of an extension of the righthand section of the frame, the extension being efiected by attaching to the right-hand set of standards side boards designated in the drawings as 54 and 55 and the said side bars 54 and 55 of the extension of the frame are so located that the carrying belt 52, will have the same inclination as the guide board 50; that is to say, the inclination will be from the front upward in direction of the rear. It will be understood, as shown in Fig. 1, that the conveyer belt passes over a second drum, designated in the drawing as 52, which is journaled in the front lower portion of the machine frame.

The prime feature of the invention consists in the construction and location of a cutting sickle M and a feed barM'. The cutting sickle is made of metal while the feed bar is preferably constructed of wood; and the feed bar M, is located within the central space of the frame at the-left-hand side of said space. This bar is horizontally located and its teeth are given a rearward inclination. The inclination of the feed baris practically thatof the division board 29, and the feed extends from the front of the machine rearwardly beyond the rear face of the machine, and the said feed bar is of such length, that as shown in Fig. 4, it extends beneath the left-hand guide finger 48, or it may be made to extend over that fingerif in practice it is found desirable; and the outer or forward end of the feed bar is shaped to correspond to the outer end of the said guide finger 48. The feed bar is adapted to have a somewhatrotary reciprocating movement, and this movement is brought about by connecting the bar near its center by a link 59 with a crank arm 60, formed upon the inner end of a driven shaft A journaled in suitable bearings in the left-hand set of rear standards, as shown in Figs. 1 and 3, while the bar is held in its inclined position and yet is free to have movement by means of links 61, connected at intervals with the upper left-hand edge of the bar, and the left-hand bottom sill 26, or the links at their outer ends may be connected with a sill placed in suitable position over the said outer left-hand sill 26, it being understood that the links pass through suitable apertures 29 produced in the upright guide board 29, as illustrated in Fig. 3.

The feed bar M, is so located that as soon as a corn stalk enters between the guide fingers 48 it engages with the stalk, and as the machine advances the stalk of corn is constantly given arearward feed and inclination as well as an inclination in direction of and over the guide board 51, the action upon the stalk commencing near thelbottomwhe'n it first enters the machine, or below the point where the lowest earis located, and continuing along the stalk to the upper portion thereof, or above the point where it is possible for an ear to be produced or located.

The inclination which is given to the stalk is due to the slanting of the teeth and likewise to the location of the teeth. The division board will effectually prevent a stalk from leaning over to the left, while the teeth of the feed bar, in addition to carrying the stalk rearward, forces the stalk to lean over to the right, thereby preventing it interfering with other stalks subsequently entering the machine. I

The cutting sickle M is made of metal, as heretofore stated; its teeth are formed upon its upper face and stand vertically. The outting sickle runs in parallel lines, or practically so, with the feed bar, and is supported in guides 62, attached to theinner face of the guide board 51; and in addition to the support of the guides 62 the cuttingsickle is supported also by links 63, pivoted to one side of the said sickle, preferably the right-hand side, and the lower ends of the links are carried downward and pivoted to a bar 63 located beneath the frame of the machine, as shown best in Fig. 2. The cutting sickle M, is given a rotary reciprocating movement by connecting with it between its center and upper edge a link 64, which link is preferably connected by a crank 65, with a driven shaft B journaled in the rear portion of the frame, preferably where the lower sill 26 connects with the rear uprights, as shown in dotted lines in Fig. 2. Thus in operation it will be observed that as the standing corn enters the machine the feed bar inclines it rearward and to the right, and by so doing the cutting sickle is brought into engagement with the portions of the stalks carrying the ears and separates the ears from the stalks. The ears when separated roll down the inclined face of the guide board 51 upon the carrying belt, being taken by that belt upward to the rear portion of the machine.

A horizontal platform beam 66, is projected from the lower portion of the inner or righthand set of rear standards, and from this beam at its outer or rear end an upright 67, is carried, connected with the upper side extension 55 of the frame, as shown in Fig. 2'; while between the center and the rear end of the platform beam 66 a shorter upright or standard 68, is located. The. two standards or

uprights

67 and 68, are ordinarily connected at their loft-hand sides by a beam 69, bracing these two standards; and upon the shortstandard 68 an angle lever 70, is fulcrumed, carrying at its shof'ter and lower end a weight 71, the upper end of which angle lever is attached to the upper rear end of the cutting sickle M. This cutting sickle has a rotary facilitated by the lever and the weight. The two

extension standards

67 and 68, are erected in order that the lower end portion of the elevator frame H, may be pivoted between them. The elevator frame extends beneath the upper rear end of the endless carrying belt 52, and at right angles to that belt outwardly beyond the right-hand side of the machine. The elevator frame may be raised and lowered in any approved manner; usually, however, a yoke 72, is pivoted to the frame, the yoke having attached to it a rope or chain 73, which is carried upward over a suitable guide pulley 74, located at any suitable point upon the rear portion of the machine, the rope or chain being fastened at its rear end to any convenient portion of the machine.

The elevator frame carries an endless apron 75, which passes over a suitable drum at the upper end of the frame and another drum located at the lower end. The drum at the lower end of the frame is the only one shown in the drawings, as it is the driving drum, and it is designated as 76, being shown in Fig. 5. The axle of this drum extends through the frame of the elevator and through the short extension standard 68.

The manner in which the parts are driven is as follows: Upon the left-hand side of the machine, at its rear, a supporting wheel A, is journaled upon a suitable shaft A, the shaft being journaled in the rear left-hand set of standards, as shown in Fig. 3. This wheel is also a drive wheel and is preferably made quite wide, and its periphery is provided with spurs or the equivalent thereof, which afford the wheel a firm hold upon the ground. The other end of the shaft carries a pulley a, and this pulley is connected by a belt a, with a similar pulley a held to turn upon a shaft a secured upon the outer left-hand rear standard, as shown best in Fig. 2, the pulley a having connected with it and turning upon the shaft a gear a larger than the pulley a but not as large as the pulley a. The gear a in its turn meshes with a pinion a which is fast upon the driven shaft A carrying the crank arm which communicates motion to the feed bar M. The belt a as it revolves, is engaged by an idler a located upon the lefthand base sill of the frame.

The gearing at the right-hand side of the machine, or that which is adapted to drive the endless carrying belt 52, the cutting sickle and the elevator, is preferably as follows: A

combined driving and supporting wheel B,

corresponding to the wheel A, is journaled upon a shaft B, journaled in the right-hand rear set of standards. The shaft B, carries at its outer end a driving pulley b, which pulley is connected by a belt b'f with a smaller pulley b which revolves upon a shaft B secured in the upper right-hand side of the machine frame, as shown bestin Fig. 5. The

pulley 12 is connected with a gear b the pulley and gear turning upon the same shaft;

and the gear 12 meshes with a pinion 12 which pinion is secured upon the shaft carrying the upper or driving drum of the ele vator or conveyer. gages with a second pinion I); this pinion is fast upon the outer end of the driven shaft B which is connected by the crank arm with the cutting sickle, and imparts movement to that shaft.

The elevator is driven from the right-hand set of gearing, and is accomplished by placing a beveled gear 6 in clutch connection with the driven shaft B and this beveled gear meshes with a like gear I)", fast upon a shaft b which extends rearward in direction of the elevator, as shown in Figs. 5 and 7, being journaled at one of its ends in one of the uprights adjacentto the elevator; and the shaft 12 carries at its opposite end a gear I), which through the medium of an intermediate gear b meshes with a gear I), the latter gear being attached to the axle of the driving drum 76 of the elevator. An idler 5 is made to engage with the driving belt I) of the right-hand set of gearing. I desire it, however, tobe distinctly understood, that although the arrangement of the gears above set forth is the one preferred, said arrangement may be changed Without departing from the spirit of the invention. I desire it also to be understood, that as shown in Fig. 8, the cutting sickle in addition to the weighted lever 70, may be provided near its forward end with a spring 77, attached to the sickle at a point preferably where one of its links 63 connect with it, the other end of the spring being attached to a take-up 78 in order that more or less tension may be applied to the spring, the said take-up being secured to the guides 62 or another stationary part of the machine. The spring is adapted to assist in starting the sickle upon its backward movement; this spring may be used in addition to the Weighted lever 70, or the lever may be omitted.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1.
