CORN -HARVESTER.

.EPEGIFI'GATIQN forming part of Letters Patent No. 333.170, dated February 2, 1886.

Application filed June 11, 1884.

To all whom it 11mg concern.-

Be it known that I, JOHN I. XVOLF, a citizen of the'United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Corn-Harvesters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in corn-harvesters.

My invention relates to that class of cornharvcsters in which a shocker is combined with the cutting apparatus.

The machine is mounted upon tractionwheels having a train of gearing connected therewith,and the corn is cut by rotary knives driven by chain gearing, the corn being carried from the front to the rear of the machine by endless chains having a series of toothed carriers attached to them and dropped horizontally into a shock-holder consisting of two frame-sections hinged at their outer ends and connected detachahly at their inner ends, and when a sufficient quantity of corn is therein deposited it is clamped and bound, and the shock rotated to a perpendicular position with the ground surface, when it is dropped to the ground, the holding and clamping devices being instantaneously released at the same time and the shock left standing, the corn being cut and deposited in the shock-holder from two rows at a time. As themachine advances, the ground is cleared for a considerable dis tance, and the rows of shocks are placed as wide as possible apart. 7

The machine can be used to out either two rows or but one, and for the former purpose two sets of cutting and conveying apparatus are used, and the driving-gear is arranged to throw one or both of these sets into operation, as may he required.

Figure 1. is a side elevation of my improved corn-harvester and shocker, the dotted lines of the latter showing its movement when operating. Fig. 2 is a rear view of the machine with the shock-holder in position for receiving Serial No. 134,599. (No model.)

Fig. 19 is a view of thi spring-lateh, to which the end of the bindingchain is attached. Fig. is an enlarged view of a part of one of the carriers by which the corn is elevated and carried to the rear of the machine. It also shows the manner of connecting the chain thereto.

A is the corn-harvester, which consists, in part, of the horizontal bed-rails or stationary part I, extending from end to end of the machine, and supported at the frontby a pair of truck-wheels, B, and at the rear by the wheels B and axle w, which latter is pivoted in bearings on the underside ofthe rails I. The frame proper of the harvester, which carries the cutting apparatus and the devices for elevating and depositing the cut corn in the shocker, is of nearly triangular shape in side elevation, its front end terminating in an angle low down, while the rear part of the machine is considerably elevated, as will be seen by reference to Fig. 1. It is adapted to be raised and lowered, as well as to be tilted, so as to cut corn at different heights.

The machine-is designed to out two rows of corn at a time and deposit the corn in the shock-holder, but is also adapted to cut sin gle rows when required. It is provided with twosets of cutting and elevating apparatus, one of which can at any time be used independently of the other. These are supported one on each side of the two long bed-rails I, which extend from the axle far enough forward in the central longitudinal line of the machine to allow the truck B to clear the endsof the guideway-rails in turning, and to facilitate the handling of the machine in cuttting one or two rows. The entire movable frame with its attachments is supported by means of the engagement of the teeth of the rack w with those of the pinion w, (seen in Fig. 1 and more clearly in Fig. 10,) and which will be described hereinafter.

The traction or main drive-wheels B are placed at the rear of the frame in order to more evenly balance the machine when the.

shock is suspended at the rear of the same. Each of the drive-wheels B drives the set of knives, carriers, and spirals on its own side through a train of gears, H, consisting of a large spur-wheel,f, which is bolted to the inside of the hub of wheel B and is concentrie therewith. This drives the pinion fon the outer end of a short transverse shaft, 6 which latter is pivoted in bearings on the rear uprights of the frame, and lies behind and parallel with the axle in a plane above the latter. The pinionfslides on a spline of the shaft 0 in throwing it into and out of gear with the spur-wheelf. The inner end of shaft 6 has a sprocket-wheel, e, thereon, and it is connected with a sprocket-wheel, e on the shaft 6 directly above, by a chain-belt, c. This latter shaft has also on the inside of the chute E sprocket-wheels carrying the chain belts e of the carriers 6, and driving the short shaft 11 at the foot end of the chute. This latter shaft is pivoted in bearings on the rails b and 11 of each guideway, and has a sprocket-wheel, d", at each end, with which the chain-belts e engage. From the shaft d the power is transmitted to the short shaft 01 and bevel-gear d, which drives the vertical shaft 00 on which the disk a and knives a a are fastened atthe extreme lower end of said shaft a just below the rail b, as seen in Figs. 1, 5,11, 12. and 13. A. short chain belt, (1, connects the shaft d with the shaft (7, which drives the knifeshaft a On the extreme end of the shaft 6 which extends across the top of the chute '13 outside of the side boards of the latter, is a bevelwheel, g, which engages another on the end of theinclined shaft h. This lattershaft is coupled at the forward end on each side of the chute with the rear end of the shaft 2' of the spiral D by a universal coupling, 71 thus operating the spirals simultaneously with knives and carriers by the same system of drive-chains and sprocket-wheels.

The lower horizontal frame-bars, If and b, which form the inner and outer rails of the guideways C, respectively, are under the axle, and a considerable space is left between the outer bar, If, and the inclined bar b above it, through which space the axle 20 extends to allow the wholeframc with its devices to be raised or lowered to any desired height in operating the machine, as seen in Fig. 10, in which the dotted lines show the frame lowered. The means for this adjustment will be described hereinafter.

The cutting apparatus consists, first, of a pair of segmental knives, a, each let into re-.

cesses equal in depth to the thickness of the knives in the disk a, so that the top surface of the knife-blades t shall be flush with that of the disk. The disk is securely fastened on the lower end of a short vertical shaft, a", in a sleeve, a", cast in one piece with a case covering the bevel-gears by which the rotary knives are driven. A portion of the case is broken away to show the construction in Fig. 12. The gear-wheels are by means of the case protectedv from obstructions such as blades, stalks, or dirtduring the operation of the machine.

The outer or cutting edges of the rotaryknives a a are eccentric to the orbit of the disk, the peripheral line of the same beginning at a point at the forward angle, a about three-fourths of an inch from the edge of disk a, and ending at a point about two and threequarters inches from the latter, being proximately tangential thereto. The corner or angle a is rounded and the blade beveled from the under side, so that it enters the stalks eas ily without breaking them. The stalks are caught and severed between the rotary blades a a and a long fiat blade, I), which is stationary, being bolted securely at each end across the top of disk at in rear of its center, with its lower surface as nearly in contact with knives a a as possible without touching them.

Its front or cutting edge is beveled on top and is slightly curved near the outer end. As seen by reference to Fig. 13, it is fastened to the inner guideway-bar, b, and extends obliquely forward toward the opposite bar 1/ at at an angle of about forty-five degrees. An angular bracket, 0, is bolted to bar I), and the rear end of knife I) is dovetailed therein, as seen in Fig. 15, and fastened byabolt. The opposite end of the knife is bolted 011 its rear edge to an arm, I), which latter extends from a crossbar, I), in rear of the knives, across the guide way. This arm forms a brace in the plane of the knives, as well as a support for the knife I). As the knives a a revolve, their cuttingedges pass that of knife b throughout the outer one-third of its length, giving a shear as well as rotary out by the movement.

To insure the passage of stalks to the knives, a flat guide-bar, If, is bolted to rail b extends rearward in line with knife I), its extreme end lapping onto the point of the latter on the front edge. The cornstalks, as each row is straddled by the guideways O, are cut and fall between the spirals D onto the carriers e, and are elevated to the rear of the machine and dropped into the shock-holder. (Seen suspended at the rear end of the latter in Figs. 1 and 2.) The chute E and the spirals D are inclined, so as to form an angle with the bedrails of the frame, and the shock-holder is pivoted high enough to allow it to rotate the shock, the butts of the corn being about one and a half foot from the ground when the shock is thrown up, ready to drop. The spirals D are long flat rods in, bent spirally overashaft, i, and attached thereto by spokes i. Each end of rod 7c is bent inward and fastened to the shaft. The convolutions are about eighteen inches in diameter and nearly the same distance apart. Shaft i is pivoted at the front end, in the top of an angular brace, i, at the front of eace guideway-bar, and its rear end is coupled to gearshai't it by a universal coupling. The cutting apparatus and elevating devices are supported upon the movable frame B, the rear end of which is in form of a buttboard for the shock.

The inclined rails Z) project in rear of the frame, under boards L, to the ends of which are pivoted, one on each side, the shock-turn ers G and G, (seen in Figs. 1, 2, 3, and 4,) and to these the two sections F and F of the shock-holder F are pivoted. The shockholder sections are quadrangular in shape, and are constructed of straight rods m m, with ring ends, which clamp pipe-bars forming the upper and lower ends of each section. The upper pipe bars, 0, are pivoted about their middles in ring ends (1 q of each of the shock-turners G and G, and the sections hangloosely therein, so that when the two sections are disconnected they will each swing outward. The lower pipe-bars, a and a, are provided with connecting and disconnecting devices. One of these bars has hooks 2 3,

which enter openings at in sleeve-pieces a on the opposite bar, and these hooks are held by springlatches a, extending in opposite directions along the bar a, and are operated by springs 7 within the pipe-bar. (See Fig. 16.) The spring-latches. a have their inner ends connected by pivoted rods a to a Tshaped head on one end of a short crank-lever, a", which extendsdiametrically through the pipebar a, and which, when partially rotated, disengages latches a from the books 2 3 of the ring-pieces a on the opposite bar, and the two sections fall apart, as before stated. pare the shock holder for receiving the cut corn, the two bars a and n of sections F and F are connected together, as seen in Fig. 2, and in the enlarged detail, Fig. 16, the latches engagingthehooksautomatically. Theclamping devices consist of a chain, m on section F, which is attached by one end to spool r of the shock-turner. G on that side, and extends over a small pulley, O, on the end of bar 0, thence down the section and around a small pulley, m, )ivoted in the fork of the outer bar, in, of section F, thence on the outside of a bar, in, pivoted by its lower endto the same fork, and through a loop, in", on the upper end of this bar. After passing through loop m the end of chain in is caught by a right angled hook, n, of the opposite section. This hook is pivoted at its angle between ears 1) at the top end of bar 1'), the latter being attached to the middle of a short cylindrical bar, as seen in the detail N of Fig. 2. A spring-wire, about one-fourth of an inch in diameter, 29. extends through a hole near the middle of bar 11", each end being extended back and a turn taken around the ends of bars p, p", and p, consecutively, and secured to each end of the latter near the lower end of section F. The object of this wire to connect the hook p with the short cylindrical bars p, p", and p, and to form a reactionary spring-frame to cause the hook and the chain p, (seen connected to the loop-armp ot' the former,) when disengaged, to be thrown back onto section F The loop-arm p" of hook p extends at right angles from the latter and lies on the outside of the bar 1). The chain 12, Connected thereto, extends down to the lower end of the section, and is connected with the arm j of a rotating spring-latclnj, pivoted on the bar a near its outer end, as seen in Figs. 2 and in Figs. 16 and 19.

The shock-turners G and G are each made of two flat quadrantshaped frame-s, g and g", pivoted on the outer and inner ends of a shaft, 1-, outside of the two supports it t, on each side of the end ofbar b, as seen in Figs. 1, 2, 3, and 4. The one on the lefthand side of the machine has a spool. ordrum, 1', but G, on the right of the machine, has none. The outer frame, has its arms q (1 curved laterally inward toward g and their ends lap onto the ends of the arms of the latter (which are straight) and are fastened thereto near the rings (1 q". On the outer end of shalt 9 is a fixed ratchet'wheel, 0' and between this and the ratchetwheel u is piv- To preoted loosely a hand-lever, 1;. (See Figs. 3and 4.) The teeth of ratchet-wheel 1' extend in one direction, and the teeth of the loose ratchet-wheel 11. extend in the opposite direction. Ratchet-wheel u is in one piece with the sprocket-wheel u. The hand-lever v has two loose pawls pivoted one upon each side, and as it is turned upward the outer pawl, o, engages with ratchet-wheel r and turns shaft 0' and drum 1", winding up chain m on the drum 7*, and the hook p and its spring-frame are drawn to the center over the top of the shock, as seen in dotted lines, Fig. 2, after which the shock is tied above the clamp by a cord or wire. The pawl 1' (seen pivoted to bar t, Fig. 3,) holds the shaft r from turning, when the shock is compressed, by its engagement with the teeth of the inside ratchet-wheel, T, which is rigidly attached to shaftr. After the operation of compressing and tying the shock, the latter is partially rotated until brought into a perpendicular position by turning handlever v in the opposite direction. In this operation pawl 11 becomes disengaged and drops down, as seen in Fig. 4, and pawl 11 now engages the teeth of ratchet-wheel u, turning sprocket-wheel a, which, by means of the connection of chain 8, turns the large sprocket-wheel a on the end of shaft 20 By reference to Fig. 1 it will be noticed that a long lever, 11., is pivoted at its front end in the rim of wheel o (or on a pin on the latter,) and extends back to the top of arms 8 on the shock-turner G. At this point lever u forks, as seen in the top View, Fig. 3, and is pivoted to the top ends of the two converging arms or braces s 8, both of which can be seen in this figure. From the ends of arms ssa rod-brace, 8, leads down to the rear end of arm q". Now, as sprocket-wheel a is rotated from right to left, shock-turner G is elevated by means of lever u, and at the same time the shock-turner G on the opposite side of the machine is also elevated and partially rotated by means of a crank, if, on the end of the transverse shaft 16 extending across the machine in rear of the butt-board. The connection of thelever uon the right-hand side of the machine with shockturner G being the same as with G the illustration of the latter is deemed sufficient- In Figs. 1 and 5 apron-boards L are seen. These, as seen in Fig. 1, are hinged to the lower edge of the rear top board, L, which extends back over the shock-turners and hangs down while the shock-holder is being filled. By the operation of elevating the shock-turners, chain 0,connected with arm f of the latter, is pulled downward around pulley 0 (seen in dotted lines on the inside of bar b,) and its upper end being connected with a projecting arm, 0, on the top edge of apron-board L, the latter is thereby elevated to a horizontal position, as seen in Fig. 5, which shows the apron-boards broken off. As the boards L are elevated, they press in the top ends of the projectingflat vertical springs 0 on the butt-board,

and when they reach the horizontal position the springs are released and thrown outward under them, thus supporting each one. These apron-boards receive the few stalks which are out before the shock-holder is again connected.

The final operation of releasing the shock and dropping or setting the same may be understood by reference to the several figures. When the shock-holder is thrown up with its inclosed shock, the two sections F and F stand nearly perpendicular, as seen in the dotted lines, Fig. 1, which shows a portion of the shock-holder in dotted lines, and the operator in rear of the machine now seizes the bellcrank lever n and partially rotates it, disengaging the connecting devices on pipe-bars n and a, and the two sections F and F instantly separate, the pivoted hook j on pipe-bar n being released. The pull of chain m on the point of hook p throws up the loop-arm p of the latter, as seen in dotted lines in detail N, and is released therefrom. Hook p and its chain 19* are now thrown back onto section F by the reaction of spring-wire p, and

the two sections of the shock-holder, now being clear of the shock, which is dropped up right, are again lowered and connected, the apron-boards L swung down to the position seen in Fig. 1, and the operation of cutting the corn and filling the shock-holder repeated as before.

To let the frame B down, and to adjust it for cutting the corn at different heights, it is provided with the toothed rack w, (seen in Fig. 10,) which, with the other parts, forms the device K. The rack is of segmental shape, and stands vertically between rails 12 and I) on each side of the frame, to which its ends are fastened. The rack is in front of the axle, and its teeth are engaged by a fixed pinion, w, on the latter, which is held thereto by a curved guard-bar, in rear of the axle and parallel with the rack, and is secured to the latter at its top end and to the rail 12 at the lower end. The frame is lowered by its own gravity, the axle w rotating in its bearings and causingthe pinion w to traverse the rack.

To elevate the frame, a chain, w around a drum-pulley, w, in the middle of the axle,

Fig. 5, leads from the under side of said pulley forward in the central longitudinal line of the machine between rails I to the short transverse shaft J, pivoted in bearings on the under side of the latter'in rear of the truck B. Shaft J is composed of an inner shaft, y, and an outer hollow shaft, y, as seen in the View Fig. 8. It is operated by a hand-lever, y which is looselypivoted to theinner shaft, 3 on the right-hand end between the outer notched Wheel, 8, on the end of the same shaft, Q and the notched wheel w on the end of the outer shaft, 3 As seen in Fig. 9, this lever has a slot, y, therein, which allows it to be raised endwise, so as to disengage a fixed lug, on its inner side from notches in wheel '10 on the outer shaft. WVhen it is thus raised and disengaged from wheel 10, it can be engaged with 'wheel 8 of the shaft y by means of latch-rod y which is operated by pressing its latch y when grasping the lever. To elevate the frame and its mechanism, the hand-lever 1 is down, with its lug y in a notch in wheel w, and it is thrown backward, winding chain 10 onto shaft 3 from the under side, rotating axle w and its pinion w rearward, unwinding chain 10 from off pulley w" as the axle is rotated.

To retain the frame at any desired height, a latchrod, w, (seen on the right hand of bars I, Figs. 5 and 7,) engages a notch in wheel 10 on this end of the hollow shaft y. In Fig. 7 this wheel is not seen, being on the inner side of lever y. Latch-rod w extends back from a foot-lever, w, (seen pivoted at the forward end of the bars I on the right-hand side,) and its top or treadle end extends up through the foot-board M at the right-hand end of the latter. To tilt the frame, apair of jointed levers, z and 2', connect the front end of the inner guide way-bar, b,with each end of the inner shaft, 3 lever 2 being rigidly fastened to the shaft and lever z secured in the same manner to the end of bar I). These bars are short and about the same length and pivoted at their connecting ends. \Vhen desired to tilt the frame either up or down, the lever is disengaged from the outer shaft by raising it up, as before stated, latch-rod y engaged with a notch in wheel 8, and at the same time latchrod 10, on the opposite side of bars I, is disengaged from wheel 9 on the left-han'l end of shaft y, and lever 1/ thrown either backward or forward, as required, the adjustment being retained by the engagement of latch-rod 10 with the wheel 9, the disengagement of the latter being performed by foot-lever 11 in the same manner as that of the latch-rod w.

The driver can manipulate both the handlever and foot-levers easily from his position on seat I) over the truck B on the front end of the coupling-bars I.

The chain elevators have a link with a screwbolt, 6, cast integral therewith, as seen in Fig. 20, by which the carriers e are fastened to the chain. In the view shown the top part ofe is threaded internally, and a rou lid-headed screw engaging therewith secures the end of the bar thereon,which latter is bored through for the purpose and slipped over it.
