structions and combinations of parts hereinafter described and claimed.

Referring to the drawings, forming a part hereof, Figure 1 is a side elevation of our improved harvester. Fig. 2 is a similar view from the opposite side. Fig. 3 is a top plan view. Fig. 4 is a front elevation. Fig. 5 is a rear elevation. Fig. 6 is a detail of the knocker arms and their actuating mechanism. Fig. 7 is a plan view of the husking rollers. F 1g. 8 is an end view thereof. Fig.

9 is a detail view partly in section of the mounting of the vertical rollers. Fig. 10 is a reduced plan view of the inner end of the tongue. Fig. 11 is a transverse vertical section through the husking rollers.

In the practical application of ourinvention, we provide a frame comprising longitudinal bars a, having connected to each end thereof, uprights a, the uprights being connected at their top by upper longitudinal bars and by cross bars a. At approximately the center of the longitudinal bars are uprights a, extending above the upper longitudinal bars and connected at their top by a cross bar a The uprights are braced to the longitudinal bars by suitable braces a, and the cross bars are braced to the uprights by suitable braces a An axle B having a cranked portion 1), is journaled in bearings l) upon the lower longitudinal bars, and upon the ends of the axles are journaled the power wheels b 7), the power wheel if being without the frame, and the power wheel I) within the frame.

The power wheels are constructed as shown in Fig. 2, of a hub I)" provided at each side with peripheral flanges U, the flanges having a plurality of spaced bolt holes I), the holes in each flange being in alinement with the holes in the opposite flange. The rim 6 of the wheel is connected to the hub by means of the spokes If, and the spokes are formed from a rod of suitable diameter bent into angular form as clearly shown in Fig. 2, that portion at the bend being flattened and engaged by the head of the belt I), passing through the alined holes in the flanges and secured upon the opposite side of the opposite flange in any suitable manner. The ends of the red are screw threaded and are passed through perforations in the rim of the wheel and in the mud hooks b and are engaged by a nut b, for securing the parts together. It will be evident from the description, that each bolt on the flange engages four spokes, and that the spokes not only retain the rim in its proper position but the mud hooks also.

The cranked portion of the shaft B, extends upwardly, to approximately the level of the top of the frame and is inclined slightly forward to be out of the way of the operating parts of the ma hine.

A countershaft O, is journaled upon the central uprights a, the ends being extended beyond the framework and one of them provided with a sprocket wheel 0, engaged by a chain c, passing downward and over a sprocket wheel I), secured to the inner face of the power wheel 12*, while upon the opposite end is a second sprocket wheel 0 engaged by another chain c passing over a sprocket wheel I) secured to the face of the opposite power wheel. Outside of the sprocket wheel 0 upon the shaft C, is a bevel gear 0', meshing with the bevel gear (1, upon the end of a vertical shaft (1, sup orted by a bracket d having at one end a co lar (1 j ournaled on the extreme end of the shaft O and at the other end a collar d, engaging the shaft cl below the bevel gear.

The lower end of the shaft (Z, is supported in suitable hearings in a horizontally arranged frame d, connected to the frame A by the brackets d, and above the bearings is a sprocket wheel d engaging a lug chain D, supported on the horizontal frame by a plurality of pulleys d, j ournaled at the corners thereof as clearly shown in Fig. 3.

A second bevel gear 0 arranged upon the shaft O, within the frame and on the opposite side of the machine, meshes with a bevel gear 6 upon a shaft c, supported by a bracket 6 having upon one end a collar 0 engaging the shaft C, and upon the other end a collar 6, engaging the shaft 0 below the bevel gear. The lower end of the shaft is supported in a suitable bearing upon a frame c supported by brackets e connected with the frame A, and above the bearing is a sprocket wheel 6 engaging a lug chain E, the lug chain being IIO supported by pulleys e journaled on the inner edges of the frame.

The inner runs of the lug chains D and E, are adjacent to each other, and move in the same direction, and the extreme front edges of the frames (Z and e are beveled outwardly, while the frames are arranged at a slight angle to each other, the horizontal opening between the frames decreasing toward the rear.

A shaft F, is j ournaled upon one side of the machine in bearings f in brackets f X secured to the upper longitudinal bar withinthe framework, the inner end of the shaft being provided with a bevel gear f, meshing with a bevel gear 0 upon the shaft C, and at its outer end with a bevel gear f, meshing with a bevel gear f upon a transverse shaft f journaled in bearings f on the frame. The outer end of the transverse shaft is provided with a fly wheel f and the inner end with a bevel gear f, meshing with a bevel gear f upon the upper end of one of a pair of vertical shafts f The shafts f are provided with rollers f and are journaled at their upper ends in a cross bar on the frame, and at their lower ends in brackets)" depending from the said cross bar, and the ends of the shaft not provided with the bevel gear, are slidable in slots f inthe bracket and in the cross bar, the shafts being normally maintained in their inward position by plate springs f A pair of knocker arms G, are arranged immediately in front of the rollers f the knocker arms being pivoted upon a pin g, connected with a bracket g, supported by the cross bar, and are vibrated by an eocentricf upon the shaft F. One of the knocker arms G, is extended above the pivot, and is connected by means of a link 9 with a bracket 9 upon a strap 9 encircling the eccentric, the other arm being connected below the pivot by a link 9 with the bracket 9 and both of the arms are provided with teeth 9 projecting in the same direction, the teeth upon one of the arms being staggered with respect to the teeth upon the other arm.

It will be evident from the description that when the shaft is rotated the arms will be vibrated in opposite directions, since one is connected with the eccentric below and the other above its point of pivotal attachment.

The arms are arranged as above described, so that while one arm is moved toward the opening between the rollers to knock the ears from the stalks the other arm Will be returning to its original position, the arms. acting alternately to remove the ears from the stalks.

An inclined conveyer H, is arranged at one side of the machine, the inner and lower end of the conveyer being adjacent to the knocker arms. The conveyer comprises a trough shaped body having a bottom h and side boards h, the lower end of the trough being closed as at 7L while the outer side board is extended upwardly to the upper longitudinal bar. as at h to form a hopper. Shafts 72, are journaled at each end of the conveyer, the shafts being provided with sprocket wheels 72, within the trough, for supporting a plurality of endless chains h, connected at intervals by vanes h. The conveyer chains pass from the lower corner of the lower end of the conveyer to the upper corner of the upper end of the same as indicated by the dotted lines in Fig. 1, and are driven by means of a sprocket it upon the extended end of the upper shaft h the sprocket being connected by a sprocket chain h", with a sprocket wheel 0 upon the shaft 0 without the frame.

A husking device K comprising a frame is having journaled therein a plurality of rollers is supported at the end of the conveyer H, the husking device being inclined downwardly toward the front of the machine. The frame of the husking device is provided upon each side with side boards, k having projecting upwardly therefrom arms k connected by a rod is, to which is secured a curtain k extending backwardly and over a strap is connecting the side boards, the free end of the curtain being provided with a weight M, whereby to maintain the curtain in a taut condition.

The husking rollers as clearly shown in Fig. 7 are four in number arranged in two series of two each with a space between the series, each roller being provided with longitudinal series of teeth is", and with longitudinal series of depressions lc the seriesof depressions being arranged intermediate the series of teeth. The rollers are so arranged within the frame, that the teeth of one mesh with the depressions in the other.

The outside rollers are journaled in fixed bearings lc in the ends of the frame, and the upper ends of the shafts thereof are provided with bevel gears 16, meshing with bevel gears 7c", upon a transverse shaft k journaled in bearings is upon the frame of the husking device, and driven by means of a sprocket wheel is on the shaft without the frame, which is engaged by the sprocket chain it before described as driving the conveyer H.

The inside rollers are mounted at each end in bearings k in the upper end of rods k pivoted in the ends of the frame and depending therebelow, the free ends of the rods being connected by a spring k.

Upon the ends of the shafts of the husking rollers adjacent to the transverse shaft k, are pinions k having a double row of teeth, meshing with the teeth of a similar pinion k secured to the shaft of the inside roller. A fifth roller 15 is arranged in the space between the series, and at a higher level than the husking rollers, the said roller being journaled in bearings 7c on the ends of the frame, and being intended to guide the ears in oppobv a brace m with the cross bar site directions into the grip of the husking rollers.

A conveyer M is arranged with its inner end below the lower end of the husking device, for carrying the husked corn from the machine to a wagon or other suitable receptacle. This elevator is arranged in a trough composed of a bottom m and side boards m, and has journaled in each end thereof shafts m m having thereon within the side boards sprocket wheels m, engaged by chains m", connected at spaced intervals by vanes m. The lower end of the elevator is provided with a guiding board m for directing the husked corn onto the elevator, and the chains are driven from a third shaft m journaled in the trough and provided with sprocket wheels m engaging the chain, the outer end of the shaft being provided with a bevel gear m engaging a bevel gear m upon a stud shaft m, journaled in the frame, the stud shaft being provided with a sprocket wheel m connected by a chain m, with a sprocket wheel 0 upon the shaft C.

The forward cross bar a is arched upwardly at its center to form a Ushaped bracket m the bracket being connected A m" secured to this U-shaped bracket is connected with the outer end of the elevator M for supporting the same. 7 A- tongue N, is pivoted to the extended end of the shaft B, by means of a plate n, spaced apart from the tongue by pieces of wood n, the pieces of wood being spaced apart from each other to form a slot 12? for a purpose to be hereinafter described. The plate and tongue are secured together by suitable bolts 71; traversing the tongue, the plate and the intervening pieces of wood; and a bracket n is secured at each end to the front upright and spaced apart therefrom, to permit the reception of the plate between the bracket and the upright, thus retaining the plate in position against the upright but allowing of a tilting movement of the frame with respect to the tongue.

A bar is pivoted to the tongue on the inner side thereof, and depends therebelow, and to the center of the bar are connected the double trees 7;, in any suitable manner. The lower end of the bar is engaged by an evener 0, comprising a rod 0 connected with the bar and passing upward through the slot M, to a chain 0, which passes over a pulley o journaled at the rear upper corner of the frame, the end of the chain being connected by a rod 0 with a second chain 0 passing over a pulley 0 at the opposite rear corner of the machine, and connected at its end With a third rod 0", passing for ward alongside the machine to a third chain 0 passing over a pulley 0 at the front of the machine, and to a swingle-tree 0 at the opposite side of the machine from the double-tree.

By the above described mechanism, one horse hitched to the swingle-tree would pass between the row of corn being harvested and those yet unharvested, while the horses hitched to the double-tree would be entirely away from the unharvested corn, and since no neck yoke or other connection is used between the horses hitched to the double-tree and the horse hitched to the swingle-tree, there will be no breaking or knocking down of the stalks.

In operation my improved harvester is driven up the row with one horse between the u nharvested corn and the row being harvested, and the others on the outside of the row being harvested, thus bringing the stalks in the row into position to be engaged by the conveyer chains 1), E. The chains pass the stalks backwardly toward the vertical rollers f at the rear of the machine which are separated a suflicient extent to allow the stalk to pass but not the corn thereon. \Vhile the stalk is engaged by the rollers the knocker arms vibrating backward and forward across the space between them, snap theears off and knock them into conveyer H, the stripped stalks passing outward at the back of the machine between the rollers. Since the rollers are spring pressed toward each other they may yield for the passage of a larger stalk or any slight obstruction which may come between them.

From the elevator ll the snapped corn is delivered upon the husking rollers where the husks are seized by the teeth and stripped from the ears, the husked ears being delivered by the wagon elevator from. the machine.

Any suitable means for elevating and dc pressing the frame with respect to the ground or for tilting the frame with respect to the tongue may be made use of.

For convenience of the driver we arrange a spring plate 7- at the front of the machine upon which is secured a seat R, a foot board 1*, being attached to the frame in a position for supporting the drivers feet.

It will be evident from the description and from an inspection of Figs. 4 and 5, that the bars composing the framework are arranged in such manner as to leave a passageway longitudinally of the machine whereby to per mit the passage of the standing corn. The cross bar between the front and rear ends of the lower longitudinal bars are omitted, and the axle is thrust upward to a level higher than the cross bars connecting the ends of the upper longitudinal bars.

Since the vertical rollers at the rear of the passageway permit the passage of the stalks while preventing the passage of the ears, the cars will be turned backward from the stalks, when the stalks are engaged by the rollers, in the most favorable position for engagement by the teeth of the arms.

The provision of the fly wheel on the shaft for operating the vertical rollers, steadies their movement and prevents choking upon the passage of a larger stalk or other obstruction.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is- 1. In a corn harvester and in combination, a frame provided with a passage there through for receivin the standing corn, conveyer chains on eac side of the passage, a pair of vertical rollers at the rear of the passage, one of said rollers being yieldingly mounted, a pair of knocker arms pivoted on the frame, and depending in front of said rollers, spaced teeth on the knocker arms, the teeth on one arm being staggered with respect to the teeth on the other arm, means for vibrating the arms in opposite directions, a conveyer adjacent to the arms, and leading upward therefrom, a plurality of husking rollers at the upper end of the conveyer, a conveyer for receiving the husked corn from the husking rollers and carrying it from the machine, wheels for supporting the frame, and means whereby the wheels may actuate the conveyer chains, the vertical rollers, the knocker arms, the husking rollers and the conve'yers.
