GRAlN-HARVESTER.

SPECIFICATION forming part of Letters Patent No. 372,339, dated November 1,1887.

I Application filed August 4, 1883. Serial No. 102,763. (No model.)

To all whom it may concern:

Be it known that I, ANDREW STARK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Grain-Harvesters, which are fully set forth in the annexed specification and drawings pertaining thereto, from which any one familiar with the art to which the said improvements pertain can make and use the same.

Figure l is a plan of my machine. Fig. 2 is an elevation viewed from the grain side. Fig. 3 shows the same parts seen in Fig. 2 viewed from the opposite side, with the grain'platform, cutter-bar, and reel cut away. Fig. 4is a view from the front of all parts appearing behind the vertical plane-cutting the main driving wheel axis. Figs. 5, 6, and 7 show details of construction of the shipping-cam, shifting-clutch collar, and bevel-gearing by which the motion of the binder is produced and intermitted. Fig. Sis a plan, and Fig. 9 is an elevation, of the grain-receiving platform and birider-platform. Fig. 10 is a plan, and Fig. L1 is a vertical section, of the needle and divider guard in the rift of the binder-platform. Figs. 12 and 13 are details of the rod which operates the shipping cam-opcratinglever and its connection with and relation to the clutcl'i-shifting mechanism. Fig. 14 is a section taken at the line 2 z of Fig. 12.

A is the driving-wheel carrying the main driving-gear A, secured to it. i

.B is the inner segment, supported by the sill F of the base-frame. To the segment 13 is secured the bracket 13 which is also attached to the sill F.

A is a gearpinion meshing with the main gear A and secured to the shaft A, and connected by suitable clutching mechanism to the bevel-gearA which is loose on the same shaft and meshes with and drives the bevel-gear A, journaled in the bracket 13 at right angles to the shaft A and carrying the sprocket-wheel D to drive the subsequent mechanism, which it does by means of a chain over the sprocketwheels 0, G, and H, hereinafter described.

F isthe outer sill of the base-frame of the machine, made, preferably, of angle-iron, extending from the inner divider around the drivingwheel and all connected mechanisms, except theplatform and cutter-bar, to the point f, crossing the framesill F behind the drivewheel, extending under the bii'ider-platform, and joining the frame-sill F at a point about midway between'the platform-frame bars or sills F and F These parts F, F, F, F, and F, framed together as described, constitute what I shall, for convenience, call the baseframe of the machine. I do not in this ap plication base any claims upon the structure of this frame, having covered them in my application filed August 4, 1883, Serial No. 102,762. To this base-frame are secured the segments on both sides of the wheel, the inner segment, B, being secured to the crossbar F, as shown in Fig. 4.

F is the finger-bar, constituting, also, the front sill of the platform, formed, preferably, of angle-iron and secured fast to the end of the baseframe, and by suitable brackets also to the lower end of the inner segment. To this frame and to the cross-bars named are secured the upright posts F, F, and F which, with the cross-bar F next described, afford supports for the grain switching, packing, and

binding mechanisms. To the base-frame is secured the binder-gear standard K, which has the horizontal arm K overhanging the binderplatform and the horizontal arm K underneath said platform and secured firmly to the base-frame by means of-suitable brackets or intervening blocks.

F is a cross-bar for supporting certain of the binder-driving mechanism. It issecured to an upward'extension of the segment at one end and at the other end to the post F by means of the bracket G hereinafter described.

0 is a sprocket-whee1 secured at the end of the roller 0, journaled on the base-frame near the discharge end of the cutter-bar platform and parallel to the same. This roller is provided with teeth 0, which revolve through slots 0 in the receiving-platform E. The purcured a bevel-gear, G, meshing with the gear G which is secured upon the upper end of the vertical shaft G, journaled in the bracket G and having the erankarm G.

' Near the lower end of the vertical shaft G is secured the vertical roller or drum G, which is preferably toothed or corrugated or provided with ratchet-vanes, as seen in Fig. 8. The purpose of this roller is to drive the butts of the grain as it is delivered from the grainearrying platform backward and carry them across faster than the heads are being carried, and so throw the grain into an oblique position corresponding to that of the himler-platform and operating mechanism. To further assist; the same process I provide the corrugated or ribbed swinging butt board G secured at one end to the crank-arm G, from which it receives its motion, being guided at the other end by the loop 1, having the eye g running on the horizontal rod 9, which is sleeved at one end on the shaft G, between the shoulders of the bracket G and rests the other end upon horizontal support r]",jutt.ing out from the bindergear standard K.

It will be readily understood that the rotation of the crank G" will cause the butt-board G to push the grain in the direction of its length, and will also carry the butts across toward the binder faster than the heads are traveling, thereby further assisting the turning of the grain into the desired oblique position. The support g may be provided with notches, as shown in Fig. 9, in which the turned-over end of the rod ma. rest, so that y the position of the butt-board may be adjusted toward or from the binder-arm as the length of the grain may require, being set closer in short grain and farther in long grain, so that the band may fall in the proper position on the bundle whatever the length of the grain.

H is asprocketwhcel secured upon the shaft H, which isjournaled upon the cross-bar F lt extends forward and carries upon its forward end the mechanism for driving the reel. It extends backward and has its rear endjournaled in the spur K of the arm K of the binder-gear standard K. Upon this shaft are loosely secured two beveled gear-wheels, H"

- and I'l",'and between them a double-clutch collar, H, having the slot h, through which protrudes the pin h, rooted in the shaft, and by means of which the collar is made to revolve positively with the shalt, but with longitudinal play thereon, so that it may engage the cl utchshonlders h" and h upon the hubs of the gearersj, which act alternately upon and pack, forwardthe flowing grain in the usual manner of such devices. The position of the crank J" is such with relation to the cranks j that the divider J passes down into the flowing grain simultaneously with one of the packers j", and at the lower limit of its stroke, as hereinafter explained, it stands while the binderarm takes the bundle, and by means of the simultaneous action of the divider and one of the packers the bundle is by them sustained at two points and so prevented from tipping over while being grasped by the binder-arm. The cranks j" being longer than the crank J", the packers have a longer stroke than the divider J, which acts also as a packer, and by that-longer stroke the packers advance the butts of the grain faster than the heads are advanced by the divider. Thus the packers and the divider, act-ingalso as a packer, complete the turning of the grain into the oblique position necessary in order that it may be acted upon by the obliquelyplaced binder. The binder-platform being somewhat higher than the surface of the grain carrying platform, the grain must be forced up a slight slope at some stage in its advance from the grain-carrying platform to the top of the binder-platform. The oblique position of the binder relatively to the grain-carrying platform makes the intervening distance greater on the front side than on the rear side-that is, greater at the butts of the grain than at the heads or at the middleand hence the slope, if continuous, would be greater at the heads or middle than at the butts. As illustrated in Fig. 8 of the drawings, the receivingplatform is made substantially level ovcra triangular space, and the rise is all effected in the bimler-platform, which thus slopes uniformly. The result would not be materially different if the slope were distributed equally fromthe delivery end of the earrying-plattorm to the top of the binder-platform. As illustrated, the grain delivered onto the receiving platform encounters and is obstructed by the upward slope of the binder-platfoi m sooner or if the slope were made continuous would encounter a steeper slope-at the middle or toward the heads than at the butts, and is thereby retarded at the point of such obstruction, while advancing freely under the action of the forwarding devices at the butts, thereby further assisting the turning of the grain into the desired oblique position. The beveled gear H meshes with the beveled gear L, fixed on the shaft L, which extends through the arm K of the binder-gear standard K. To the outer face, or to one of the spokes of the gear-wheel L, is fixed the crank-pin Z, from which extends the connecting-rod L, which actuates the lever L of the rockshaft L" underneath the binder-platform, and carrying at its rear end the needle or binder-arm M. The binder-platform N is slightly inclined upward from the receiving to the discharge end, and has the rift 12, through which the divider dethe needle, the train of gears which drives it,

scends and the needle or binder-arm ascends to grasp the bundle. The binder-platform N is secured to the arm K of the binder-gear standard K, or to the main baseframe beneath it, by suitable brackets or intervening blocks at any convenient points.

r is a trip-finger, which consists of the up bent end of the rock-shaftR, which lies under the binder-platform alongside of and resting in proper bearings secured to the arm K of the binder-gear standard K, at the forward end of which it has the crankarm 7', which is hinged to the lowerend of the red a the point ofits connection with said rod being adjust able upon the rod by any convenient means. As shown in the drawings, this adjustability is secured by providing the lower end of the rod 1 with aseries of holes, oneabove another, into any one of which the crank-pin of the crank-arm 1" may be inserted. The rod i eX- tends up alongside of the binder gear standard K, is bent over, and passes under the arm K, being at any convenient points supplied with proper slide-bearings, and at the upper end is given a direct upward turn, bringing the end 0* close alongside the shaft H, inside the angle between that shaft and thearm K of .thebinder-gear standard and .i nsidethe point of the-shipping-cam-operating lever S, for apurpose hereinafter explained. A spring, 8, is attached either to the rod o or to thetleverarm 1', and at theotherend to any fixed point P is a slide-bar having one pointof support at on the bindergear standard K and another upon the cross-bar F". It is provided with the shippingcam V, fixed uponits uppersurface and extending up close, to the surface of the double clutch-collar Hflnpon which there is provided the stud and roll If, which engages with the shippingcam V, as herein after explained. a r

On the inner surface of the gear-wheel L is placed the cam S, adapted to engage with the spur S of the shipping-cam-operating lever S, thereby'performing a function hereinafter eX- plained. e'

To the slide-lever 1? there is secured the collar T on thevshat't H: This collar has the flange t, and between it and the spur K, which furnishes therear bearing for the shaft H, there is placed coiled about the shaft the spiral spring t, tendingtotl'irow the collar T- toward the gear-wheel H v The combined action of these parlsviz., the trip with its connected levers and springs,

and the packer and divider systeni and the gears which drive itis as follows: The normal position of the double clutch-collar is engaging and driving the gear-wheel H", and thereby the gear-wheel J and the packerarms j and dividenarrn J In this position the trip-finger rstands above the binding-platform, and the point r of the rod 0" is in the position shown in Fig. 12, holding the shipping-eam-operating lever S against the flange t of the collar T, keeping the spring t compressed and holding the'slide P at the'rear limit of its play in its hearings, in which position the shipping-cam upon the upper face of the slide is in the position shown by the dot ted lines in Fig. 6. In this position, also, the clutch-collar H being out of connection with the gear-wheel H the wheel, and through it the needle-driving mechanism, is out of connection with the driving-power. Thus geared and connected the packers and the divider are performing their otlice of raking the grain from the receiving-platform and gathering it into a gavel on the bindingplattorm, and as the divider separates the gavel and by its downward sweep presses it forward, its pressure, acting against thetrip-tinger 1-, tips therockshaft 1t and withdraws the pointrot' the rod 1" from behind the shipping cam-operating-lever S, and thereupon the spring t, reacting against the flange tof the collar T, slips it forward on the shaft H, thereby swinging the shipping-camopcrating lever into such position that its spur S will be reached and acted upon by the cam S. on the gear L, and at the same time brings the shipping-cam Vinto the position shown by the full outline in Fig. t5that is to say, so that its'facc V will be exposed to the stroke of the stud-roll b onthe clutch-collar H which is revolving constantly with the shaft H. As the stud-roll strikes the face V ofthe shippingcam V, the clutelr'collar H is thereby caused to slide on the shaft H, out of connection with the gear-wheel H and into connection with the gearwheel H --that is to say, to be disconnected from the packer and divider operating mechanism, which then comes to rest, and to be connected to the binder-operating mechanism, which is therebyput. in motion.

This is the position represented in Figs. 5 and 6. The first effect of the motion thus commu nicatcd to the gear-wheel L is to cause the needleto be thrown up by the tipping of the rock-shaft L", by means of the connectingl-inlc L, and in proper time with that motion to drive the tying-mechanism. (Not shown or described here, but which is connected to the rear end of the shaft L, and actuated by the cam and gear wheel P, which also carries the dischargerarm 0, whose function of discharging the bundle is performed immediatelynpon the completion of the tying.) The next effect is, that when the tying is completed the cam S, on thegear-wheel L is by the revolution of that wheel brought into contact with the spur S upon the shippingcamoperating lever S, and forces-the end S of the lever against the flange tot the collar T, causing the collar to slide on the shaft H, compressing the spring 25, carrying the slide-bar t rearward and rewherein the continued revolution of the shaft IIO H, carrying with it the double clutch-collar H brings the stud-roll it against the face of the shipping-cam, by which contact the clutohcollar H is slid forward on the shaft H, disengaged from the gear H, and reengaged with the gear H", this being the initial position-the binder out ofgear and the packers and divider in gear. The clutch collar H has at each end but a single tooth, and the gears H and Hhavelikewise each but asinglcclutchtooth to engage that of the clutchcollar The clutclrcollar is shifted only when the studroll If reaches the shipping-cam V on the slide P, and therefore only once and always at the same point in its revolution. The slidebar P, shifted, as described, by the action of the pressure against the trip-finger ofthe grain supplied by the packers, isliableto bcshifted at any time when the pressure becomes sufficient to move the trip finger; but after the slide P has been shifted the packers will continue to act until the revolution of the shaft II has brought the roll If against the shipping-cam and shifted the clutch-collar H. This in sures that the packers will always be re leased from the driving-power at the same point in their course, and so will always stand at rest in the same position. This position is such that the dividerarm has just passed down through the rift n in the binder-platform N and stands with its point partly below the platform, so that when the needle M rises through the same rift it may pass close alongside the divider arm through the rift made and maintained in the grain by that arm. Now, there being only one tooth on each end of the clutchcollar H and only a corresponding single tooth on each of the gears with which it engages, it results that even after the clutch collar 11 has been shifted from the gear H to the gear H although the motion of the packing and dividing mechanism ceases, that of the binding mechanism does not begin until the single tooth of the clutchcollar H has come into engagement with its mate on the gear H. The partsare so timed that unless the jarring of the machine or other outside cause has disturbed the position of the needle and its driving-gear since the last bundle was bound, the clutclrtooth on the gear H is in position to be immediately engaged by the corresponding tooth on the clutch-collar H as soon as the latter is shifted; but if it should be otherwise-if the clutch-tooth on the gear II should be ahead of or behind its true positionthe only result would be that the clutchcollar H would miss it and complete its revolution before engaging it; but when so engaged the action of the parts would be as designed and described-viz., that the needle would come up through the platform while the divider is standing with its point protruded down through the rift therein and preserving a clear path for the needle through the grain, as described. Similarly, at the close of the binding movement, if the divider and packers shall have been jarred out of position, the

clutch-collar H when shifted by the stud-roll Ir, may miss the clutch-tooth of the gear H", and so may complete its revolution before effooting engagement with said gear, but when engaged its movement will be in perfect time, as described, and the only result of the delay in effecting the engagement will be that when the packers start, the bundle will be formed more quickly by reason of the accumulation ofgrain against and just outside of the divider during the delay.

In order to prevent the point of the needle coming up on the wrong side of the divider, and thereby becoming entangled with it, I provide the sheath W, ofsheet metal, secured to the approach N of the binder-platform, having the tongue \V, extending over the rift n and bent so as to stand obliquely edgewise in the vertical plane of said rift, leaving the space 0 at one side for the divider to enter as it descends, while the needle enters the rift from beneath the platform on the other side of said tongue, which thus, acting as a switch, serves to insure the proper clearance of the points of the divider and the needle.

X is a grain-guard secured to the frame at any convenient point in front of the cutterbar at such height that the standing grain will neither pass under nor fall over it to any great extent. It extends back over the discharge end of the cutter-bar platform outside the points of the packers, and may be secured to the rear end of the overhanging arm K of the binder-gear standard K. Its purpose is to keep the standing grain out of reach of the packers and prevent it becoming entangled with them, while at the same time allowing the prostrate grain to pass freely under it to the binder without offering any obstruction to the heads.

Y Y are rods or slats fastened to the grainguard X, and thence extending sloping downward to within a short distance of the receiving and binding platforms, where they may terminate without other support. The packers are designed to work between them. Their purpose is to keep the inflowing grain closely down on the binder-platform while being compacted by the packers. I prefer to secure them at one end only, thereby gaining the advantage of having them slightly yielding as the grain accumulates under them and adapted to act as a spring-compressor.
