SPECIFICATION forming part of Letters Patent No; 605,650, dated June 14, 1898.

' Application filed July l7, 189 6. Serial No. 599,552. (No model.)

.To all whom it may concern." 1

Be it known that I, DARIUs T. PHILLIPS, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois,have invented anew and useful Improvementin Corn-Harvesters, of which the following is a specification.

My invention relates to improvements in corn-harvesting machines of the class more especially adaptedto operate upon two rows of standing cor'n at once and is in the nature of an improvement upon acorn-harvesting machine shown and described in Letters Pattent of the United States No. 587,535, granted to me Augustfi, 1897. This machine, which is adapted to be drawn across a field of standing corn and to straddle and out two rows at once, operates to pick up fallen corn and bend all stalks in I a forward direction to facilitate the cutting and prostrate them forward against elevating mechanism which lifts the stalks and deposits them from both sides into a binder located between and in front of the cutters, the binder operating to tie the stalks into bundles and discharge them between the rows that are being operated upon.

My present object is to provide certain improvemen'ts'in the construction of the frame and operating mechanisms to the end of rendering the machine particularly light in weight, easy to handle in the field, and desirable and eficctive under all conditions.-

To the above ends my invention consistsin the general construction of my improvement-s and also in details of construction and combinations of parts, all as hereinafter set forth and claimed.

In the drawings, Figure l is a side elevation of my improved machine with the binder and certain other details left out to avoid confusion and with parts broken away; Fig. 2,

. a top plan view'of the machine with the binder section taken on line 8 of Fig. 6 and viewed in the direction of the arrow.

A A are traction-wheels fixed to opposite end portions of a hollow rotary axle B. On the axle are bearing sleeves or boxes B B which are connected together by an upwardlybowed brace or supporting bar B provided at its center with a threaded socket-piece 25. Parallel poles or shafts O C are fastened at their rear ends to sleeves O on the axle just beyond the sleeves 3' Birespectively, and are curved outward at their forward end portions, as shown. On the outer eudportions of the axle beyond the traction-wheels are loose to be drawn by two horses, which are hitched to the-whiftletrees and to pole-strap rings 3 on the free ends of the poles O 0, whereby the paths of travel of the horses are adjacent to those of the traction-wheels.

. D is a frame which carries the operating parts of the machine and formed, preferably, of steel tubing, rods, and bars, all as light in weight as possible consistentwith the strength required. Forming apart of the frame-D is a frame or supporting bar D, preferably in the form of an inverted U and T-shaped in cross-section. The legsor opposite end portions of the bar D extend through and are movable in vertical guides B, fastened to or integral with the sleeves B B The guides B are provided with set-screws 0, adapted to be tightened against the legs of the bar D to fasten them immovablyin the guides. On the supporting-bar D is a bracket or casting D provided with a vertical bearing opening directly over the socket-piece If for thesh'ank of a screw 15, which works in the socket-piece. At the upper end of the screw is an operating handle or crank i and thefscrew is held against longitudinal movementin the bracket D By turning the screw i when the set screws? are loosened the bar D, and consequently the entire rear end portion of the frame D, may be raised and lowered with reference to the axle.

D is a forward-extemling barorstrip, preferably of hard wood, and fastened toward its rear end upon the bracket D The forward end of the strip D is secured to the upper end of a vertical bar D", which at its lower end portion passes through a bearing-sleeve p on the frame 1) of a caster-wheel p Surrounding the ba-rD is a spring 11, confined between the sleeve 1) and a stop a on the bar. On the lower end of the bar D is a sharpened and forwardly-curved pick-up 91 and above the pick-up the bar carries a pulley a". A wire cable or other flexible medium m is fastened at one end to the sleeve 27 of the caster and extends downward under the pulley n and thence upward over a pulley n on the end of the strip D to a rod on, to one end of which it is secured. The rod m at its opposite end is fastened to an operating-lever m on the strip D At the side of the lever is a segmental rack miwith which a spring-pawl 011 the lever and controlled by a handle on normally engages. Turning the lever in the backward direction raises the bar D in the sleeve 1) and elevates the forward end of the frame D 011 the caster, while movement of the lever in the forward direction causes a lowering bygravity of the forward end of the frame. The spring a tends to lessen the strain upon the cable m and attendant parts and renders the matter of raising and lowering the forward end of the frame easy to accomplish.

Secured at their ends to the lower end portion of the bar D are brace-bars D which extend outward toward the traction-wheels and thence forward.

D is a guide-bar fastened at its center against the under side of the strip D and extending at each side outward or laterally, forward and downward, describing curves, as shown in Figs. 1 and 2. At its lower ends the bar D is fastened to the forward ends of the bars D and the parts are there pointed to form the pickups Z shown.

D is adivider-frame which may be formed of a continuous rod or bar fastened at its ends to the lower ends of the supporting-bar D and shaped to produce the parallel parts 7; 7t, inward-inclined guides 75 7c and front, At its center the part 7.3 is secured to the lower end of the bar D, whereby the strip 1) and divider-frame are held in rigid relation, both forming part of the frame 1).

On the axle 1 is a sprocket-wheel 1', from which all. the moving mechanisms in the machine are driven. On the bar D are bearingbrackets 72/, ft, and 71F, in which is journaled a shaft 72). Loose upon the shaft adjacent to the bracket 7: is a sprocket-wheel hflconnected by a drive-chain 11 with the sprocket-wheel 6. One side of the sprocket-wheel 70 is serrated to afford a clutch member, and sliding upon the shaft adjacent thereto is a clutch memher 705, actuated by means of a handle 7L, in position to be moved. with the foot to engage and disengage the sprocket-wheel clutch member. The sliding clutch member is feathered upon the shaft,whereby when the clutch members are in engagement the shaft is turned from the sprocket-wheel 7L4. Fixed upon the shaft 7L3, in the positions shown, are beveled gears 7L h.

E E are elevator-shafts journaled at their rear ends in brackets f and extending forward in a downward-inclined direction to suitable bearings (not shown) carried by brace-rodsf f. At their rear ends the shafts E E are provided with beveled gears fflwhich mesh with the gears 7L7 h, respectively. On the shafts E E are coincident sprocket-wheels f, and on the shaft E is an extra sprocketwheelf, which drives the binder-shafts,hereinafter mentioned. On the parts 7; of the divider-frame D at points coincident with the sprocket-wheelsf are brackets 70 having longitudinally-extending slots 7;, as shown in Fig. 5. Adjustably fastened in the slots 70 are the shafts of s nocket-whecls 7t". Extending over the sprocket-wheels 7L3 and under the coincident sprocketwheels It are ele- Vator or carrier chains it provided with fingers h. The construction is such that the outer sides of the elevators, afforded by the chains and fingers, extend in an upper and inward inclined direction, and the fastening means for the sprocket-wheels 7t" are such that they maybe raised and lowered in the guide-slots 7t to tighten or loosen the earrierchains. The elevator-fingers h, which I prefer to employ, are bentdownward at their outer ends, as shown in the figures. Fastened against the bars D D of the frame D is a board D affording an abutmentat the back of the machine. The elevator-shafts extend through openings in the said abutment.

F F are stationary cutters fastened at their inner sides against the parts it of the dividerframe and at their rear ends against the lower edge portion of the abutment. The knives are formed with inclined and scalloped cutting edges, as shown most plainly in Fig. 1-.

G and G are prcsser or guide boards pivoted toward their forward ends upon pins 6 on the bars D to swing in the horizontal plane, and at their rear ends they extend close to the abutment and swing over the cutters. On the bars D are springs c, which bear against the guide-boards G G and tend to swing thelatter inward to the position shown by full lines in Fig. 2 and by dotted lines in Fig. l.

Cords or other flexible mediums (1% are at tached to the upper ends of the guide-boards G and pass over the top of the strip D, where they connect with opposite ends of a helical, spring 0 The tendency of the spring e is to draw upon the cords and keep them taut, the cords themselves operating as guides for holding the cornstalks against the elevators, as hereinafter described.

If is a twii'ie-binder of a common construction, except as to the needle-guard and discharger. The shafts (Z d of the binder are geared together in the usual way, the shaft d being driven by a chain from the sprocketacross the surface of the plate 0.

wheel f on the shaft E. On the shaft 01, at the side of the needle II, is a needle-guard H comprising a plate 0, pivoted upon the shaft 01, and having a flange c in the arc of a circle of which the shaft d is the center, the flange extending over the outer edge of the needle. At the forward edge of the plate 0 is a flange or stop 0 in the pat-h of the needle, and at the rear edge of the said plate is a similar flange or stop 0 also in-the path of the needle. The needle in its movement slides posite side of the plate cfrom the needle isa plate 0 substantially of the same shape as the plate o, pivoted upon .the shaft d and sliding in contact with the said plate. On the outer edge of the plate 0 is a flange 0 describing the arc of a circle of which the shaft d is the center and movable along the outer surface ofthe flange cof the plate 0. At the rear'edge of the plate dis a flange or stop 0 Fastened upon the plate 0 is a finger'c provided at its free end with a hook 0 adapted to engage and release the rear edge of the plate 0 In the backward movement of the needle to the position-shown in Fig. 6 it slides along the plate 0 tothe stop 0 and then swings the plate with it across the plate a to the stop a". In the forward movement of the needle to the position shown in Fig. 7 it moves acrossthe-surface of the plate 0 to the stop 0 and then slides the plate 0 across the surface of the plate 0 until the latter is engaged by the hook on the fingerc A guard for the needle is necessary to prevent stalks from falling behind the needle and clogging the binder. The present construction aifords "a guard which ac-' complishes this purpose. In the backward movement of the needle the rear edge of the plate strikes the binder-frame and is prevented from moving farther than the position shown in Fig. 5. Thus the guard isprevented from projecting into the path of the stalks as they are raised by the elevator.

The rods f, before mentioned, extend from their fastenings at k upward, as shown, and then parallel with the shafts E'E, being fastened at theirrear ends to the bar D, as shown in Figs. 1 and 3. The rodsf carry housings f which cover the shafts between the sprocket-wheels carried bythe shafts. These housings prevent the revolving shafts from becoming entangled with corn-silk or the like; Fastened upon the housings ad jacent to each of the sprocket-wheels f is a spring-rod f which extends upward and in-' ward and thence downward' These rods operate as guards or shields to maintain the cornstalks depositedin the binder away from As the cornstalks are deposited in the binder they rest'in a hopper formed by spring-rods f which are fastened at their upper ends to the bars or rods f and extenddownward and On the op ping each otherwithout engagement, as indicated in Fig. 2. The means for discharging the bundle from the binder consists in a disk b, eccentrically mounted upon the end of the binder-shaft d, an eccentric ring I), in which the disk 17 rotates, and a discharging arm or finger b fastened to the ring. opposite the arm or finger b the ring is pivotally attached to the lower end of a rod b which extends upward and is fastened against the rod or barv f. In the rotation of the binder-shaft d the disk b is rotated in the ring b,.which latter is held against rotation by the rod 19 In operation-the arm 19 travels an elliptical path, moving upward in rear or to the left of the stalk-receiving hopper before mentioned and in its downward movement describing the course indicated by the dotted.

which may be formed of a single bar fastened at its center to the said strip, arched upward at opposite sides of the strip to pass over standing corn, and extending thence vertically downward loosely through guide-loops d on the poles O O. The lower ends of the pick-ups a are pointed and bent for'ward, as shown. The lower ends of all the pick-ups a, ct, Z, and n are preferably in the plane of the under side of the frame D. The drivers seat X is mounted upon the rear end portion of the'strip D and mounted on the machine are a twine-box X and a tool-box X In operation the horses are hitched to the whimetrees s and pole-strap rings '3 as before described. In traveling across a cornfield the divider D of the machine moves between the two rows of standing corn to be cut, and the horses, the stalk-guide points Z, and the traction-wheels travel at .the outer sides of said rows. The cable 8, to which the whiffietrees are attached, will slide freely through the hollow axle to compensate for any unevenness in draft and prevent the wheels from veering. The pick-ups at will engage any down corn which may. extend across the paths of the horses and bend it inward into position to be engaged by the pickups a, and the pick-ups n will tend to engage any down corn that extends acrossits path and move it into position to be guided to the cutters by the divider D Down corn will'be raised by the pick-ups Z and deflected inward by the guides D while upright corn will be bent forward and inward by said guides. As the cutters F F engage and sever the stalks the lower ends of the latter are At its side thence inward from opposite sides, overlap- IIO pressed inward toward the elevators by the guide-boards G G. As the stalks are out they fall forward under the pressure of the guides D and are then engaged by the fingers on the elevator-chains, which raise the stalks and deposit them in the binder to rest in the hopper formed by the separable rods f \Vhen the binder has acted to tie the bundle, the discharger 12 operates, as before described, to force the bundle from the hopper and deposit it upon the ground between the rows that are being operated upon Constructed as described the framework of the machine consists of "cry few parts, all of which are made as light as possible c011- sistent with the strength required. The axle tends to strengthen the frame very much over frames which employ no axle, and as it is at the rear end of the frame it is entirely out of the way and does not interfere with the work of the cutting, elevating, and binding mechanisms. By providing two shafts or poles connected with the axle, as described, horses hitched thereto are prevented from tram ping upon the rows of corn on which the machine is operating, and the horses are also prevented from getting injured by the guards and pick-ups, especially while turning the machine in the field. The pick-ups, disposed as described, operate to guide all the stalks which may be down properly to the cutting and elevating mechanism. The means provided for elevating the rear and front ends of the frame are simple, strong, and easy to operate, so that a driver without leaving his seat may adjust the machine quickly to the varying conditions of the corn. The cutters I I owing to their peculiar construction, sever the stalks with a slanting cut requiring very little power. These cutters have been constructed by me after careful study of the requirements, and I find that owing to the extended cutting-points separated by the scallops the blades engage and cut smoothly through the outer shells and then through the pith in a manner much more smooth and requiring less power than where continuous or serrated blades are employed.

The llexible cable extendingloosely through the hollow axle with the whifl'letrees connected at opposite ends afford a particularly desirable and effective draft connection which is out of the way of all moving parts of the machine, does not interfere with the discharge of the bundle, and presents an equalizer which is very effective for its purpose. The guide or presser boards G G direct the lower ends of the severed stalks yieldingly against the adjacent elevator-chains and the guide-cords c maintain the stalks by a gentle pressure against the elevators. This construction I find particularly effective and desirable.

The machine constructed as described is lighter by several hundred pounds than any other machine for the same purpose of which I am aware, and while I prefer to construct it in all its parts as shown and described it may be variously modified in the matter of details of construction without departing from the spirit of my invention as defined by the claims.
