SPECIFICATION forming part of Letters Patent No. 482,945, dated September 20, 1892.

Application filed April 30, 1891, Serial No. 391,108. (No model.)

To aZZ whom it may concern.-

Be it known that we, DANIEL W. HANsoN and JOHN S. FARNHAM, citizens of the United Stat-es, residing at Mineral, in the county of Bureau and State of Illinois, have invented a new and useful Corn-Harvester, of which the following is a specification.

This invention relates to harvesters, and more especially to that class thereof which are adapted for harvesting corn by drawing the cars from the stalks without pulling the latter from the ground and then husking such ears.

To this end the invention consists in the details of construction hereinafter more fully described and claimed, and as illustrated on the accompanying six .sheets of drawings, wherein Figure 1 is a plan View of this improved machine, omitting the inclined chute. Fig. 2 is a rear elevation. Figs. 3 and 4 are sections on the lines 3 3 and 4 4 of Fig. 1, the latter figure omitting that portion of the machine shown in the background of Fig. 3. Fig. 5 is a section on the line 5 5 of Fig. 3 and on an enlarged scale. Fig. 6 is a section on the line 6 6 of Fig. 2. Fig. 7 is an enlarged section on the line 7 7 of Fig. 6. Fig. 8 isan enlarged section of one pair of the huskingrollers. Fig. 9 is an enlarged perspective view of one of the gathering-wheels. Fig. 10 is a plan view of the frame containing the drawing-rolls. Fig. 11 is a rear elevation of the gears connecting the drawing-rolls with the snapper-rolls and a section on the line 11 11 of Fig. 10. Fig. 12 is an enlarged plan View of the lower end of one of the stalkchains. Fig. 13 is a plan view, and Fig. 14 a side elevation, of a modified form of a snapper. Fig. 15 is a plan view of still another form of snapper. Fig. 16 is a rear elevation of the device as illustrated in Fig. 15, showing the means for driving this modified form of s'iapper.

In the drawings are shown in various views and positions the gatherers G, the stalkchains O, the drawing-rolls D, the snapperrolls S, the elevators E, the rear elevator E, the inclined chute I, the husker H, the delivery-elevator Y, and two modified forms of snappers S and S", all mounted on a sup porting-framework F, carried by main wheels W, Whose rotation also drives the main shafts M M, to which the operating mechanism is connected. These various parts are of the specific construction set forth below or of equivalent constructions adapted to perform the same functions in practically the same manner.

One of the main wheels W carries a gear 1, which intermeshes with a gear 2 on the end of a short shaft 3, journaled in the frame. This shaft carries another gear 4, which intermeshcs with a gear 5, whose toothed hub 6 turns loosely on the main shaft M. The latter is provided with a spline 7, which engages a toothed clutch 8, adapted to be moved longitudinally thereon by a hand-lever 9, and by this means the driver, sitting on the seat Q, can move the clutch 8 so as to throw the main shaft M into or out of connection with the driving-wheel to start or to stop the move ment of this portion of the machine. The main shaft M is provided outside the righthand Wheel W with bevel-gears 10, which intermesh with bevel-gears 1 on the lower end of forwardly-inclined shafts 12, to whose upper ends are secured sprocket-wheels 13.

To brackets 14 are adjustably bolted blocks 15, from which rise stub-shafts 16, and on the upper ends of the latter are journaled sprocket-wheels 17, which stand adjacent each other at the lower front side of the framework. Around the sprocket-wheels 13 and 17 extend two stalk-chains O, which are driven by the intermeshing gears 10 and 11 above described and which may be tightened by adjusting the blocks 15 on the brackets 14, as best seen in Fig. 4. Inside these endless chains arepreferably located boards 18, around whose edges the chains travel, and to the chains are pivoted at intervals L- shaped fingers 19. At the lower end of each board 18 is a cam 20, against which the fingers strike as they move downwardly on the outer side of the chain and by which they are turned, as best seen in Fig. 12, so that as the fingers on the two chains ascend between the boards 18 they will project toward each other and into the slot between but slightly above the plane of the boards.

Above the boards are arranged inclined shields 21, whose inner edges 22 are turned downwardly, so as to form guides or tracks, against which the inner ends of the fingers 19 press as they travel upwardly, and the fingers are held thus until they slip off the upper ends 23 of the tracks. 24 are uprights supporting the boards 18, and the inner ends of these uprights are connected in pairsby parallel bars 25,as seen in Fig. 5, to form shields for the chains. Rising from the uprights 24 are brackets 26, whose upper ends are connected by broader guides 27, which also serve as tracks for the fingers on the. descending sides of the chains, and by these tracks the fingers are kept folded as they move downwardly.

Upon the shafts 12 are bevel-gears 30, meshing with bevel-gears 31 on shafts 32, journaled in boxes beneath the boards 18. These shafts extend downwardly beyond the front sprocket-wheels 17 and pass through brackets 34, wherein they are journaled. On their front ends they carry bevel-gears 33, which mesh with bevel-gears 35, that are journaled on the upper ends of stub-shafts 36, rising and inclining outwardly and forwardly from said brackets 34, and whose upper ends may be supported by brace-straps 37, projecting from the frame F.

The gatherers G consist of wheels 40, journaled upon these shafts 36 and connected with and rotating by the gears 35, but turning beneath cams 41, which are rigidly though adjustably secured to the upper ends of the shafts 36 by set-screws 42. Upon the upper side of each wheel 40 are pivoted fingers 43, each of which is of nearly the same shape as the L-shaped fingers 19, and which is likewise pivoted at its angle, and as these fingers pass around the cams 41 they are turned, as best seen in Fig. 9, so that one of their arms shall project outwardly. When they pass over the upper ends of the cams, theirinnerarms drop, owing to the lateral inclination of the wheel 40, and they no longer project beyond the periphery of that wheel. By these gatherers G the stalks of corn are caused to pass into the open front end of the slot between the boards 18 and between the inner edges 22 of the shields 21, and the upwardly-moving fingers 19 of the stalk-chains G then carry the stalks upwardly in this slot at somewhat greater speed than the machine is progressing over the ground, owing to the multiplyinggearing l 2 and 4 5.

The pole or tongue 44 of the machine is hinged or pivoted, as at 45, to the main frame F, and rising from the latter near this point is an upright 46, carrying a toothed segment 47... Pivoted at the center of the segment is a lever 48, to which is pivoted a pawl-openating lever 49, the pawl 50 engaging the segment, as is usual. The front end of this lever is bent upwardly, as at 51, and a stout rod 52 connects it with an eye 53 in the pole. By this arrangement the adjustment of the lever 48 adjusts the angle of the main frame F to the pole 44, and hence adjusts the height from the ground at which the gatherers G will grasp the cornstalks.

Beneath the stalk-chains O is a rectangular framework 60, Fig. 1U,within which are located the drawing-rolls D and the snapper-rolls S, hereinafter described, and at the front ends of the side bars of this frameworkare upwardly-curved shoes 61. Bolted to these shoes and extending rearwardly therefrom are Y- shaped guides 62, which have elbows 63 in their bodies and whose rear ends 64 are turned outwardly and bolted to brackets 65, extending inwardly from the side bars of said rectangular framework 60. At the inner ends of these brackets are eyes 66, in which are journaled the lower ends of the shafts of the drawing-rolls and the snapper-rolls. By this construction the lower ends of the stalks as the latter are drawn in by the gatherers G are passed between the guides 62, pass over the elbows 63, and are thereby directed between the eyes 66 and between the rolls.

Upon the main shaft M are mounted bevel gear-wheels 70, which intermesh with bevel gear-wheels 71, keyed upon the upper ends of the shafts 72 of the drawing-rolls, and said shafts also have intermeshing gears 73, by which they are caused to rotate simultaneously and in opposite directions. One of these shafts also carries a larger gear 74, intermeshing with a gear 75, keyed upon the shaft or trunnion 76 of one of the snapper-rolls S, and these two rolls are also caused totravel in directions opposite to each other by intermeshing gears 77.

The drawing-rolls D are provided with longitudinal ribs 78 upon their faces, and the snapper-rolls S have oval bodies 79, as best seen in Fig. 5. By this construction as the stalks are caused to pass up the slot between the two chains the drawing-rolls D (which, as will be seen in Fig. 3, are considerably inclined) will draw the stalks downwardly, be-

cause they are turning toward each other,

and meanwhile the snapper-rolls S, which are turning in the other direction, are picking the cars from the stalks in a manner which will be obvious. The front ends of the rolls D and S are slightly tapered toward the eyes 66 and the rollsdiverge slightly, as shown, whereby as the stalks pass therein and pass farther up the rolls will more tightly grasp them. The snapper-rolls are preferably so arranged by the intermeshing of their connecting-gears 77 that their fiat bodies 79 will always stand at the same distance from each other, by which means the ears will be neatly nipped from the stalk.

Beneath and outside each drawing-roll D is an elevator E, which comprises an endless chain 80, moving over sprocket-wheels 81 and 82, the latter of which has its shaft mounted in a block 83, sliding in a slot 84 and adjustable by a hand-nut 85, turning on a screw 86, connected with said block, by which means the chain may be kept taut. The upper sprocketwheels 81 are fast on the shaft 87, which at one end has a gear 83, meshing with a gear 89 on the main shaft M. .The chain has outwardlyrprojecting wings 90, so as to move in the casing 91 in the direction of the arrow in Fig. 4, and as the ears are nipped from the stalks by the snapper-rolls S they fall upon .outwardlycurved guides 92, whereby they are jects a screw 105, that extends through the.

casing, and on this screw is a hand-nut 106, as shown. When this nut is adjusted, the blocks 104 will be moved, and hence the chain may be kept taut. On the shaft 107 of the upper sprocket-wheel 102 is a sprocketwheel 108 outside the casing, and this is con nected by a chain belt 109 with a sprocketwheel110 beneath the inclined chute 1. Thus it will be seen that motion is transmitted from the left-hand part of the entire machine to drive the elevator E.

On the left-hand supporting-wheel W is a sprocket-wheel 115, connected by a chain belt 116 with a sprocket-wheel 117, mounted upon the left-hand section M of the main shaft, and this shaft carries a bevel-gear 118, meshing with a smaller one 119, which is secured upon the shaft of the sprocket-wheel 110, by which means the elevatorE is caused to travel, as above set forth. The gear 118 meshes with a smaller gear 120, which is fast upon the upper end of the shaft 121 of one of the huskingrollers 122, and this roller has sharp-headed screws 123 seated in its face, as best seen in Fig. 8. Upon the shaft 121 is a gear-wheel ,124, meshing withanother 125 on the shaft 126 of a companion roller 127, the latter having cavities 128 in its face, with which the screws 123 engage. These screws and cavities are arranged spirally around the rollers, as seen in Fig. 1. There is a second set of these devices, such as those bearing numbers 118, 120,121, 122, 124, 125, 126, and 127, similarly arranged, and to whose reference-numerals we have added a prime-mark, and all four rollers are located within the'husking-box 130, (best seen in Fig. 7,) and which box has vertical sides 132, an open lower end 133,and a numberof longitudinal parallel wires 134, forming a top. By this construction the ears of corn which pass down the chute I fall into the open upper end of the husking-box 130 and are thrown by the division-board 136 onto one or the other pair of the husking-rollers. If the ears should be shot up within the box,

they will strike the wires 134 or the sides 132 and be thereby prevented from getting out of the box; but the screwsl23 soon grasp the husks on the ears and drag the latter downwardly, so as to tear them from the cob and from the kernels of corn and drop them on the ground. The cob, with the kernels thereon, then passes downwardly over the rollers, out the lower end 133 of the husker, over the guide 137, and into the delivery-elevator Y. From the upper end of the box 130 lead straps 140, having bearings 141 at their upper ends, embracing the main shaft M. At the front end of the box is an eye 142, from which rises a rod 143, connecting with a hand-lever 144, which moves over an arc-shaped guide 145 and has a spring-actuated pawl 146, adapted to engage one of a number of holes 147 in said guide 145. By this means the operator, sitting on the seat Q, can move the lever 144 upwardly to elevate the front end of the husker H, and as the box 130 is pivotally mounted by the straps 140 and bearings 141 on the main shaft M it is obvious that when this box is moved around said shaft in the arc of a circle the gears 120 and 120 will still be kept in mesh with the gears 118 and 118.

Beneath the inclinedchute I is a strap 148, whose ends are mounted in eyes 149, rising from the framework, and which may be otherwise rigidly or detachably supported.

150 is a weighted balance or fly wheel mounted upon a vertical shaft 151, upon the upper end of which is a bevel gear-wheel 152, which intermeshes with the gear 118, and this fly-wheel serves to cause the parts of the husker to rotate steadily and firmly. When the machine is ascending a hill and thehusker would thereby be raised from its angle to a position undesirably near ahorizontal, so that the husks would not properly travel down the rollers and be treated, the operator can lower the hand-lever 144, as may be necessary to produce the successful operation of this husker.

Upon the main shaft M is a gear-Whee'l160, meshing with another 161, mounted on a shaft 162, which extends forwardly and is journaled in suitable bearings 163. At the front end of this shaft is a sprocket-wheel 164, connected by a chain belt with another sprocketwheel 166, mounted upon a shaft 167, which extends into, the elevator-box Y and carries the lower sprocket-wheel 168 therein. From this sprocket-wheel an endless chain 169, having wings 170, passes upwardly over the upper sprocket-wheel in a manner which will be readily understood. The shaft 103 of this upper sprocket-wheel is jourualed in sliding bearings 104, to which is connected a screw 105', extending through the upper end of the casing, and on this screw is mounted ahandnut 106, as shown in Fig. 2. By this means the chain 169 may be tightened in substantially the same manner as above described for tightening the chain 100 in the rear elevator E or for tightening the chain 80 in the elevator E. p

In Fig. 13 is shown in plan, and in Fig. 14 in side elevation, a modified form of snapper which we sometimes use. This comprises opon wings or doors 180, hinged at their outer edges at 181 to the rectangular framework 60, and the doors are of such width that their adjacent edges will never quite come in contact. 182 is a rock-lever, (of which it will be understood there are two, one for each door,) and the front end of this lever is connected by a link 183 with its door, while its rear end is connected by a link 184 with a circular band 185, that surrounds an eccentric wheel 186, which is mounted upon the main shaft M or upon any other suitable shaft. In Figs. 15 and 16 the doors 190 are similarly hinged or mounted in bearings 191, and upon the shafts of these doors are mounted arms 193, adjustable by means of set-screws 197. The upper ends of these arms are pivotally connected to a rod 192, and the latter connects by a pitman 194 with a crank-wheel 196, driven by or from the main or any other suitable shaft. The eccentric wheels 186 in one case and the arms 193 in the other case are so set that the doors will have a slight swinging motion in opposite directions, and this will effect the snapping of the ears of corn from the stalks in a manner similar to the action of the drawing-rolls D. Snappers of this character may be used instead of the rotating snapper-rolls D above described without departing from the spirit of our invention, and these swinging doors possess the possible advantage that they may be readily adjusted.

A team being hitched to the tongue 44 and the lever 48 being adjusted to bring the shoes 61 and the gatherers G sufficiently near the ground, the horses are driven forward and the machine properly guided to cause the shoes 61 to pass to eitherside of arow of cornstalks. The fingers 43 of the gatherers reach out and draw in whatever stalks may be slightly out of the row or may not be upright, and the fingers 19 of the stalk-chains Cpass all the stalks upwardly between the boards 18. At the same time the bodies of the stalks pass between the downwardly-rotating drawingrolls 1) and the upwardly-turning snapperrolls S, and as the stalks are drawn downwardly the ears are snapped or nipped upwardly from the stalks, the latter passing beneath the shaft 87 and resuming an upright position and without being drawn from the ground whilethe ears drop from the snapperrolls over the guides 92 onto the bolts of theelcvators E and by the wings are car- .ried upwardly and dropped over the guide 95.

delivery-elevator Y. The upper end of the latter, Fig. 2, is quite high, and, if desired, a wagon may be driven along at the side of the harvester, so that the delivery-elevator will drop the cars into the wagon. Thus it will be seen that the gathering devices are located outside the right-hand supporting-wheel W and slightly forward of the same, where they automatically gather up the stalks before the latter fall under the wheel. The strippers or snappers pull the ears 0% the same, and the husked ears are delivered into the wagon or onto the ground. The lever 9 may be operated to disengage the clutch members 6 and 8, and thereby to stop the motion of the devices at the right of the frame. The lever 48 is serviceable for adjusting the angle of the frame to the ground, and therebystripping the stalks near their upper ends onlyor throughout their entire lengths, as may be desired, and the lever 144 is, as above stated, for the purpose of keeping the rollers of the husker at a proper angle to cause them to operate successfully.

Considerable change may be made in the details of construction without departing from the spirit of our invention, and much of the specific structure of the parts is illustrated on the drawings, but not elaborately described here, because it is believed that it will be obvious to any person skilled in the art.
