SPECIFICATION forming part of Letters Patent No. 484,076, dated October 11, 1892.

Application tiled October 13, 1891l Serial No. 408,607. (No model.)

To all whom t may concern,.-

.is to effect certain improvements in the construction of devices of this character.

To this end the invention consists in a ma- A chine embodying the details hereinafter more Vss fully described and claimed, and as illustrated on the five sheets of drawings, wherein- Figure 1 is a plan View of this machine complete. Fig. 2 is a right-hand-side elevation with the supporting-wheel removed.

Fig. 3 is a left-hand-side elevation with the `supporting-Wheel also removed. Fig. 4 is a central longitudinal section through one of the banks of gatherers, giving a cross-section of the two beaters. Fig. 5 is a perspective detail of the left-hand ends of the feeder-roll and the several husking-rollers, showin g their ,driving mechanism and showing the let't edge of the presser-belt partly broken away. Fig.

,6 is a rear elevation of the machine, showing only the slide and elevator. Fig. 7 is a crosssection of the machine on the line 7 7 of Fig. 1. Fig. 8 is aplan view showing the axle, the

Vframe in rear thereof, the tongue, and the deing t0 the rear and supported bya caster-wheel,

and devices W', by which the machine is to be guided by the operator; a main frame F, pivotally m'ounted on the axle and adapted to have its angle of inclination changed and its height from the ground at the front end set, as desired, vby the adjusting devices D; the

operating mechanisms mounted upon and carried by this framework and consisting of two banks of gatherers G, rotating beaters B, above and below the gatherers, a rearwardlymoving carrier C, the husking devices H, a

transverse slide S, to which the husker delivers, and an elevator E, and the various connections for driving these several mechanisms, each and all of which are more specifically described below. ot my machine are capable of a considerable These several parts degree of modification without necessarily departing from the spirit of the invention, and while some parts might be used ywithout others or certain parts might possibly be dispensed with entirely I prefer to construct the machine about as shown and described, though I do not limit myself to the exactdetails nor to the proportions or materials used.

The supporting-wheels 1 may either be journaled on the axle A or may be keyed thereon,

and the framework F has its longitudinal side bars 2 provided with boxes 3 at about the centers of their lengths, which boxes are pivoted on the axle between the wheels 1. The tongue T has a strap-bearing 4 at its front end, which is preferably pivoted on a cross-piece 5, connecting the side bars 2 slightly in rear ot' the axle, as shown in Fig. 8. Braces 4X extend from the said tongue T and are connected movably at their rear ends to the adjacent side of the cross-piece 5 by means of elongated loops 5X, formed at the rear ends of said braces and engaging headed studs or pins on the said cross-piece. By this means the adjustment of the frame is permitted. The tongue extends thence beneath the frame and far to the rear thereof, and it carries near its rear end a doubletree 6, to which are connected singletrees 7, to which the horses mayv be hitched, whereby the machine will be pushed in front of them.

The guiding mechanism W consists of a caster-wheel 10, mounted in a fork 1l, whose stem 12 rises vertically through the rear extremity of the tongue, and a handle or tiller 13 projects forwardfrom this stem, by which the operator, sitting in his seat, can turn this caster-wheel so as to guide the machine. The horses, being attached to the tongue, will of course travel as directed thereby, and the necessity for reins is vthereby avoided, while the guiding or steering of the machine is rendered very fine.

The adjusting devices D, by which the angle of the machine to the tongue and the height of its front end from the ground may IOO be regulated, consist of -the following elements: 20 is a lever pivoted at its lower end to the tongue and moving overatoothed rack 2l, and the body of this lever is connected by a link 22 with the upper end of a bell-crank lever 23, whose lower front end is connected by a short link 24 with the rear end of the frame. The angle of this bell-crank lever is pivoted in an upright 25, which rises from the tongue. Hence the operator by manipulating the hand-lever 20 can turn the bell-crank lever 23 and raise or lower the rear end of the frame, whereby it will be turned aroundits boxes 3 over the axle A, and its frontend will be correspondingly lowered or raised.

The gatherers i are located at the front end of the framework F and are arranged in banks, which are separated so as to engage two or more rows of stalks, two of such banks being shown in the present case. Each bank comprises two side-boards 30 tapered to points 3l at their front ends and suitably supported 'by the framework. Through these boards, at about the center of their lengths, is journaled an idle-shaft 32, carrrying sprocket-wheels 33, and through the upper ends of the boards is journaled adriving-shaft 34, carrying sprocket-wheels 35. 36 are sheet-metal lingers set on edge and mounted on the shafts 32 and 34, their front ends projecting forward toa line nearly opposite the points 31. In the present case three of such fingers are shown in each bank, interposed between four sprocket-wheels on each shaft, and the sprocketwheels are connected by chains 37, moving to the rear on their upper sides.- The beaters B vare located above and below thegatherers.

The upper one comprises a shaft 40, parallel t, 48 being rigidly connected with this gear.

with and a little tothe rear of the idle-shaft 32, a polygonal roller 4l, keyed on this shaft, and combs 42, secured to opposite faces of the roller with their teeth projecting tangentially therefrom and sufficiently far to project downwardly between the side-boards 30 of each bank of gatherers and draw or move upwardly over the chains therein. The lower beater comprises a shaft 43, just beneath and parallel with the idle-shaft 32, said shaft 43 carrying a square roller 44. The right end of the driving-shaft 34 carries a sprocketwheel 34,.and the right ends of the shafts 40 and 43 respectively carry sprocketwheels 40 and 43. On the inner face of the righthand supporting-Wheel l is a ring 45, having inwardly-projecting gear-teeth, as seen in Fig. 3, and 46 is a gear engaging this ring and mounted on a stub-shaft 47, asprocket-wheel 49 is a sprocket-chain passing over this gear 48, thence under the gear 34', thence over the gear 40', thence under the gear 43 and back to the point of starting. By this means the movement of the right-hand supporting- A5l and moving over an idle-roller 52, standing across the frame just beneath the rear ends of the gatherers and over a driving-roller 53, standing across the frame nearly over the axle A and journaled in uprights 54 of the framework. Guide-boards 55 stand along the edges of this apron and have ltheir rear ends 56' curved downward and inward, as seen in Fig. l, and said boards prevent the ears of corn as they are carried up by the slats 5l from falling off the edges of the apron. The husking devices l-I are located in rear of this carrier, and the presser-belt formingaf part of said devices is driven by a sprocketwheel 69', described below. On the left-hand end of the shaft 43 of the lower beater is a sprocket-wheel 43, from which leads an endless chain 55, passing over an idle-sprocket 56, thence under a sprocket-wheel 53 on the left end of the shaft 53, which drives the carrier, thence over said sprocket 69 and back to the point of starting, and by this means the carrier is caused to move in the proper direction to carry the ears back from the gatherers, as will'be understood.

The husking devices H comprise a feederroll, a series of husking-rollers, and a presserbelt. nals on the rear edges of theuprights 54,just under the driving-roller 53 of the carrier, and is turned to the rear by means described below, the face of this roll being polygonal (preferably square) and its function is to receive the ears from the carrier, turn them so as to stand across the machine, and deliver them properly to the husking-rollers. The latter comprises cylindrical rollers 6l, arranged in parallel pairs across the machine, the rollers of each pair being revolved toward each other by the means set forth below. The presserbelt comprises an endless apron 67, moving at its rear end over an idle-roller 68 and at its front end over a driving-roller 69, on whose left end is keyed the sprocket 69', above mentioned, and by means of which the apron is moved. On the left ends of the rollers 6l are intermeshing gears 6l', certain of w'hich are provided with beveled pinions 62 on their hubs. On the inside of the left-hand drivingwheel l is a gear-ring 63, meshing with a gear 64, mounted on a stub-shaft 63 and carrying a miter-gear 64.

certain of the husking-rollers.

66 on said-upper shaft, all asbest seen in Flg. 3. By this means the turning of the left supporting-Wheel through the connections de-;y scribed drlves the husking-rollersin pairs in` the manner above set forth. As the ears fall off the upper end of the carrier they are di-j rected by the feeder-roll onto the upper pairl of husking-rollers, and the general inclinat1on of the husking devices to the rear of the machine causes the ears to move down overf the rollers. Passing under the roller 69 the ears are borne down onto the husking-rollers by the presser-belt 67, and thusv they are Y moved tothe rear until the approaching faces of the rollers'of some pair catch the husks" The husked ears pass on while the husks drop through the,

and drag them off the ears.

frame onto the ground or into a receptacle,

which, if desired, can be carried by the frame at the proper point, as well known in this art, but is not shown in the drawings. f

The slide S consists of a box-shaped body 70, extending transversely across the rear end of the frame F and having a longitudinal slot 7l in itsrear wall and an inclined directing-board 72 within its left end. The bottom 73 of this box rests on cross-bars 74 at the bottom of the casing, its left end moving under the board 72 and its right end moving under the right-hand side'A bar 2 of the frame andI delivering into a -receptacle 75.

76 is a pitman whose inner end 77 passes through the slot 7l and connects with the bottom board 73, whereby the latter is reciprobelow.

ed on aud'supported by the projecting righthand end of the box and above the receptacle 75, and an endless belt S1, having buckets 82, and moving over rollers S3 and 84. On the rear end of the latter roller is a sprocketwheel 84', which is connected by a chain 85 with a sprocket-wheel S6', mounted on a horizontal shaft 86. This sprocket-wheel has a crank-pin S6, which moves the outer end of the pitman-rod 76 to impart the reciprocating motion to the bottom board 73, as above mentioned.

On the front end of the horizontal shaft S6 is a miter-gear 87, which is in mesh with another'miter-gear S7', mounted on a stub-shaft in the frame and carrying a sprocket-wheel 87 on its hub, and an endless chain 88 leads from this sprocket-Wheel over a sprocketwheel 53 on the right end of the drivingshaft 53, which moves the carrier C, thence under a sprocket-wheel 60' on the right end of the feeder-roll 60, and back to the point of starting. By this means the driving-shaft of the carrier drives the feeder-roll, and through ying-rollers.

the connections described drives thel horizontal `shaft 86, and the. cranked sprocketwheel 86 on this shaft reciprocates the slide and also drives the elevator.

The horses being hitched to the singletrees, and preferably having their bridles connected with the tongue to prevent them from getting out of position, the operator takes his seat, manipulates the hand-lever to set the gatherers at the proper distance above the ground, starts the team, and then guides the machine by the handle 13 of the guiding mechanism. The rotation of the right main wheel drives the gatherers and the two beaters, the shaft of the lower beater drives the carrierand the presser-belt, the shaft of the carrier drives the feeder-roll and the-horizontal shaft, and the cranked sprocket on said shaft drives the slide and the elevator.- The rotation of the left main wheel drives the several pairs of husk- The ears as they are stripped from the stalks are driven onto the chains of the two gatherers by the upper beater, pass to the rear and fall onto the carrier, arel carried up thereby between the guide-boards,

against the rollers, so that the husks are stripped off the ears, and the latter pass to the rear onto the slide, down which they move into the receptacle, and from this point they are picked up by the elevator and delivered at the right side of the frame into a wagon,
