CORN-HARVESTER.

SPECIFICATION forming part of Letters Patent No. 444,723, dated January` 13, 1891. Application filed September 28, 1889. Serial No. 325,338. (No model.)

To @ZZ whom, it may concern.-

Be it known that I, DAVID W'. BLAINE, a citizen of the United States, residing at Pratt, in the county of Pratt and State of Kansas,

have invented certain new and useful Improvements in Corn-Harvesters, of which the following is a specilication.

My invention relates to a machine for cuttingvcorn, cane, or like vegetation in rows, in which the stalks are caused to pass in an upright position to a shock-gathering device, where the shock is bound in a suitable manner and then deposited on the ground in an upright position; and my invention consists in certain features of novelty to be hereinafter described, and then pointed out in the claims.

ground.

In order that my invention may be fully understood, I will proceed to describe the same with reference to the accompanying drawings, in which Figure I is a plan view of-my improved corn-harvester. Fig. II is a side view looking toward the main or driving Wheel. Fig. III is a rear view, and Fig. IV is a similar view, showing parts of the machine in the position in which the shock is deposited on the Fig. V is a detail side view of the revoluble table and its central support. Fig. VI is another detail view of the table, showing the joint of the sections, said sections be` ing separated. Fig. VII is a plan view of the table, showing the sections separated. Fig. VIII is a detail view of the means for adj usting the pressure-spring at the side of the passage for the stalks. Fig. IX is a face view of said/spring. Fig. X is a detail viewof the cutting-saw and its operating mechanism. Figs. XI, XII, and XIII are detail views of the central support above the table for the tops of the incoming stalks. Fig. XIV is a detail view showing the construction of gath ering-ngers. Fig. XV is a modification of the mechanism for operating the lingers of the central support. Fig. XVI shows the twister, the portion on the left being a side view and that on the right an end view opposite the handle.

. Referring to the drawings, A represents the framing of the machine, which is constructed preferably of gas-pipe and angle iron or steel, as. shown,or of wood, if desired.

The transverse beams a are of gas-pipe and the longitudinal beams a are of angle-iron.

B is the main or driving wheel, Cthegrainwheel, and D a caster-wheel at the rear.

The machineis preferably constructed so which the wheel is journaled, and a lever F,

sleeved at F on the shaft and extending below the shaft and sleeved at F on the arm c and having the usual pawl-and-ratchet j mechanism f. The shifting of the lever one way or the other will raise and lower the grain- Wheel.

I will now proceed to describe the operative features of the machine.

l and 2 are walls of sheet1iron or other material on each side of a passage 3, the front ends iiaring outwardly and being downwardly inclined and constituting dividers to pass on each side of the stalks. These walls extend in a curve from the front right-hand corner of the machine rearwardly toward the left of the machine, terminating at about the middle, for the purpose of carrying the stalks away from the row being cut, so' that they may be deposited in a shock a sufficient distance from the next row to be cut to allow` the team and machine to pass in making the next round.

4 is a post near the outer end of the passage outside the inner wall 2, on which are supported brackets 5, on which brackets are mounted sprocket-wheels 6 and 7 at the upper and lower ends of the post, respectively. Half-way along the passage on the outer side of the wall 2 are other sprocket-wheels 8 at Y IOO and 8 the sprocket-chain 14 passes and around the lower sprocket-wheels 7 and 9 the sprocketchain 15. Fitted loosely on the shaft 10 are sprocket -

Wheels

16 and 17, and these are caused to revolve with the shaft, when desired, by means of any suitable clutch mechanism. The clutch mechanism shown consists of sliding ratchet-sleeves 18, links 19, and an oscillating bar 20, to each end of which the links are pivoted, and which bar is oscillated by a hand-wheel 21. The teeth of these sleeves, when the sprocket-

wheels

16 and 17 are to be revolved, are brought into engagement with ratchets on the hubs of the wheels. At the rear end of the passage 3 at the outer side of the inner wall 2 is another vertical rotating shaft 22, carrying at its upper and lower ends sprocket-

wheels

23 and 24, respectively. Passing around the upper sprocket-

wheels

16 and 23 is a sprocket-chain 25, and passing around the lower sprocketwheels 17 and 24 is another sprocket-chain 26. The sprocketwheels project through the wall 2 into the passageand the inner sides of the chains run overthe curved inner surface of said wall. All of the sprocket-chains are provided with the usual pivoted gatheringingers 27 at suitable distances apart, and the upper series are so arranged that each fingerwill 'be directly over a finger of the lower series, so that incoming stalks will be caughtand carried rearwardly in a vertical position. Thesey lingers are provided with heels27a, that when the lingers are running in the passage engage with the wall 2, so as to hold them stiff to eiiectually perform the operationof passing the stalks along in vertical position over the door 28, which is slightly yinclined upwardly. At the rear ends of the sprocket-chains the slots for the wheels are made sufliciently long to permit the fingers to pass through, and just before the fingers of the second series of chains operate to catch the corn the fingers of the preceding series tilt or fall down, so that they will not carry the stalks through the slots.

To the rear of the front ends of the forward chains, so that the fingers will rst catch the stalks, is arranged the cutting device, which, as shown, (see Fig. X,) consists of a circular saw 29, so inclined that the butts of the stalks will ride up on the upper side of the sawonto the floor 28, immediately in the rear. The saw is provided with a bevel-wheel 30 on its upper side, which is engagedV by one of the series of cogs of a double vertical bevelwheel 3l, keyed to the main driving-shaft E for rotating the saw'. The other series of cogs of the double bevel-wheel engages a bevelwheel32 at right angles thereto, keyed on a horizontal shaft 33, extending toward the shaft 10. This shaft 10 is provided with a bevelwheel 34, engaged by a vertical bevel-wheel 35 atl right angles thereto on shaft 33. Both of the series of chains described are driven from vthe vertical shaft 10.

In the passage 2and fastened tothe wall 1 at 36 by suitable means is a rearwardly-projecting spring-plate 37, (see Figs. I, VIII, and IX,) that is slotted at 38 to permit the gathering-fingers to project through. rlhe upper plate only can be seen in the drawings; but the lower one is exactly the same, and hence no further illustration is necessary. The pressure of these springs is regulated by means of adjusting-rods 39, secured to them, and screw-threaded at their outer ends for the reception of nuts 40 that engage the ends of tubular casings 41, within which are contained spiral springs 42, the outer ends of which engage the ends of the casings and the inner ends bear on collars or flanges 43 on the rods 39. These spiral springs re-enforce the natural self-adjusting action of the spring plate or strip, and the nuts and rods regulate the outward position of the same, the action of the plate or strip being such that it always adjusts itself to the bulk of stalks passing through.

Keyed on the vertical shaft 22 yare sprocket-wheels 44 45, and passing around them are sprocket-chains 46 47, (an upper and a lower one,) that also pass around other sprocket-- wheels 48 49 on a shaft 50 at the outer end of an extension and adjuster 51, pivoted on the shaft 22. Pivoted to these sprocket-chains are fingers 51, similar to the lingers on the other chains. This extension and adjuster is movable backward and forward by means of a lever 52, pivoted to the frame and connected to tue extension and adjuster by a link or rod 53. The lever is set in fixed position by means of a pawl-and-ratchet device 54, as usual.

55 56 are guard-rails supported above the walls 1 and 2 by means of bars 57, secured to the walls on each side of the passage.

At the rear of the machine and at the end of passage 3 is a revolving shock-gathering table 58. This table is circular and is composed of two

sections

59 and 60, alike in shape. The curved edges of the sections are provided with upwardly-extended flanges, that constitute a rim 61 to the table. Concentric with this rim and near the center of the table are tianges, constituting an inner rim 62. Between the flanges of the table the stalks are carried by the lingers 51 on the pivoted extension and adjuster. The meeting edges of the sections of the table are provided with do wel-pins 63 (see Fig. VII) and corresponding holes 64, so as to prevent the warping or twisting of the table. At the central inner edge of one of the sections (see Fig. VI) is a single plate 65, and on the corresponding edge of the other sect-ion are two plates 65, said single plate being adapted to pass between the two plates 65", and all of said plates being provided with perforations 66, similar to key-holes. Extending up through these holes when the sections are together is the central support, consisting of a vertical projection 68,

Fig. V, on a horizontal rock-arm 69, fixed at to an oscillating shaft 77. At the basev of the projection 68 is a shoulder71forsupport- 444, 72 s al ing the table, and at the upper end of the projection is a hook 72, that passes through the oset portions of the perforations 66 when the table is in proper position, and prevents the table from being lifted 6r shaken off during a single revolution. This rock-arm has a curved hook 73, projecting toward the front of the machine under a flange 7 3, on the inner side of which engages a flange 74a of the rocking shoe 74, that retains the rock-arm in elevated position when the lever 75 that moves it is thrown forward. The lever 75 is retained in its forward position by means of a suitable device-such as a quadrant 7 6-provided with ratchet-teeth and engaged by a pawl 7Ga on the lever. (See Fig. V.) When the lever is thrown back, the rock-arm is forced down.

Vhen it is desired to deliver the shock, the sections of the table are separated and swung up into vertical position by means of the followinginstrumentalities: Thelever 75 is fixed to the oscillating shaft 77, (see Figs. I and V,) andthis shaft has a bevel-wheel 78, that intermeshes with a bevel-wheel 79 on an oscillating shaft S0 at right angles to shaft 77 and extending rearwardly. Secured to the shaft S0 is a swinging frame consisting of a rod S1, jointed to the shaft by rock-arms 82 bent therefrom. At 83 the rock-arms 82 are provided with rollers S3, that support the table near its outer edge. The rod 8l is flattened at 84, where it engages with catches 85 on the under side of the section 60. At the inner end of the oscillating shaft 77 is a bevel gearwheel 86,that meshes with a bevel gear-wheel '87 on the rearwardly-projecting oscillating shaft 88. A swinging frame similar to that carried by the oscillating shaft 8O is also carried by shaft 88, and similar reference-numerals are applied thereto. It will be observed that when the lever is operated the central support is withdrawn, the swinging frames rising, the rollers acting as a fulcrum, the flattened portions of the frames engaging the catches of the sections of the table, said sections turning thereon as on a hinge, the inner edges dropping down and the outer rising until the sections are brought into vertical position. When in horizontal position, the table is supported by the rollers and the rock-arm 69. Small brackets 89 project under the arms of the swinging frames near where they join their oscillating shafts to support the swinging frames in horizontal position, and are not in the way when the sections of the table are opened.

Projecting vertically from the frame of the machine in front of and a little to the left of the gathering-table is a tube or column 90, preferably of gas-pipe, and into this telescopes a tube 91, adjustable in height and fastened by means of a set-screw 91 or any other preferred fastening and having a tubular arrn 92 connected thereto by an elbowcoupling 93. Pendent from this arm is a tubular sleeve 94, joined thereto by an elbowcoupling 95. The tubular sleeve is made in Y two parts, the upper section having at its lower end a liange 94a, that is received by an annular groove 94b in a collar 94, that is welded or otherwise secured onto the upper end of the lower section, thus constituting a swivel-connection. These parts are all preferably constructed of gas-pipe. The tubular sleeve hangs over the center of the platform, and affords, in connection with devices mounted thereon, a support for the top of the shock.

96 is a lever pivoted to the upright tube or column, to which is attached a cord, rope, or cable, that is carried up over pulleys 98 and 99-one at each end of the tubular section E12-and mounted in brackets 98 and 99a. The cord or cable 97 extends down through an opening in the elbow-coupling 95 into the tubular sleeve or section 94 and supports a link 100, that has an opening in which swivels a headed pin 101 of a bell-shaped carrier or support 102, having an annular flange 103, within which and at the top of the bell proper are pivoted a suitable number of pendent arms or fingers 104, that, when drawn up by the cable, are within the tubular sleeve, their lower ends being curved and projecting into slots or openings 105 in the head or cap 106, that may be soldered or otherwise secured to the lower end of t-he tubular sleeve.

107v is a spiral compression-spring within the tubular sleeve or section 94, through which passes the suspending cord or cable, and which bears upon a flange 107a and upon the swiveled carrier or support 102 of the pendent arms or fingers 104, so that the tendency of said spring is to press the arms or fingers down andoutwardly through the openings in the head or cap 10G. When the operating-le` ver 9G is raised, the spring presses the arms down and spreads them, as shown in Figs. I, l1, 111, and IV.

108 is an L-shaped spring-arm, the short limb of which is secured to the collar 94C or other swiveled part of the sleeve 94, and the long limb of which extends downwardly. The lower end of this L-shaped spring-arm carries a suitable wire-twister 109, that is adapted to rotate with the arms or fingers 104. The twister carries the free end of the bindingwire 110, that runs from a spool 111 mounted on a spindle 112. Greater or less tension may be imparted to the movement of the spool as the wire is unwouud by means of a thumbnut 113, screwed onto the upper end of the spindle, and a rubber, leather, or other friction washer 114 interposed between the uut and spool.

In the modilication shown in Fig. XV the fingers are raised and lowered by means of the rod 115, extending down into the tubular sleeve and swiveled to the bell 102, and the upper end of which is pivoted to one end of a lever 116, curved downward near its midlength, where it is fulcrumed in a bracket 117. The other end of the lever is pivotally connected with a rod 118, that extends down- IOC) IIO

' 121. The end of the twister opposite the handle is formed with a stem p, having oppositelyprojecting notched projections p and p".

y The operation of the machine is as follows: The machine is drawn by a suitable team that passes to the leftof the row to be cut, the dividers passing one on each side of the row of corn. The points of the dividers will actas gatherers and rai-se up all down stalks, and as the machine advances the stalks'are brought into contact with the gathering-fingers 27 both at top and bottom. The fingers in their backwardmovement hold the stalks until the forward movement of the machine brings them in contact with the saw 29, which cuts them, the gathering-fingers of the iirst series of chains carrying them back in an upright position,the spring-adjuster 37 holding the stalks closely against the chains, and the second series of chains continuing to carry them in their backward movement to the end of the passage, where they are delivered to the extension and adjuster 5l, which in turn delivers them on the platform 5S, over which is suspended the overhanging sleeve with the elongated arms or fingers lOl, together with the combined compressor and binder attachment. The overhanging arms or fingers receive and support the top of the shock and the gathering table or platform 5S supports the bottom. The adjustable wing delivers the stalks to the center first, and through the medium of the lever 52 the operator draws it out toward the outer edge of the table. As the section between the contiguous arms or iingers is filled up the pressure of the incoming stalks, imparted by the fingers of the extension and adjuster, turns the table and the arms or fingers, which motion is checked to the proper speed by the tension on the wire at the top and the brakeblock of the table at the bottom, and thus the shock is formed. The wire supports and compresses the outside of shock at top as it is carried around and the raised rim 6l of the table supports it at the bottom. The inner rim or flange 62 keeps the stalks from crowding the center. When a complete circuit is made by the table and arms, the shock is completed. The operator by means of the clutch mechanism now stops the movement of the second series of chains, and the gathering-fingers of this series of chains are thrown down by the pressure from the incoming stalks, allowing the stalks to pass in compact. form toward the rear, and a ternporary receptacle is thus formed so that the stalks are not thrown out on the gathering-table while the shock is being delivered.

The manner in which this i's accomplished is this: The incoming stalks will cause the innermost fingers of the second series of chains to fall one at a time by reason of the packing in of the stalks, and the foremost of those packed in being pushed farther back by the incoming stalks will act on and depress those fingers toward the end of the passage one at a time, and by the time the packed stalks nearly reach the end of the passage the bound shock will have been deposited and the leaves returned to position. Therefore it isnot necessary to stop the team in making a delivery.

.The extension or adjuster 5l is then drawn toward the operator clearof the platform, and the arms or fingers lO-t are drawn up into the sleeve ont of the way of delivery. The operator now grasps the handle of the wire-twister 109 with one hand, the other holdingxthe wire from the spool, the free end of the wire having, before the operation of the machine commenced, been secured to the stem p of the twister and engaged in the notch of projection p. The wire is then crossed and the part held by the hand engaged in the notch of projection p and all the slack drawn from around the shock, when by a fewturns of the twister the shock is bound and the wire cut and the new end held in the twister. The spring-arm 10S is held in position after the arms 10i have been withdrawn from the shock by means of a pawl 122, that engagesa circular ratchet 123 at the top of the collar 94C. The lever is then drawn backward by the operator to withdraw the pivotal point (38 and IOO force down the rock-arm, the same operation causing the swinging frames to move up into engagement with the catches S5 on the sections of the table and move the sections outward away from each other, the inner edges dropping` down and the outer edges rising until sufficient space is given for the shock to drop through. The shock is steadied in its descent by the overhanging sleeve until it clears itself by its downward movement, and is thus set squarely on the ground inthe rear of the machine as the latter is drawn along. When the machine has cleared the shock, the operator drops the table or platform back into position, rextends the overhanging arms or tingers, pushes the extension and adj uster 5l to its proper position, and starts the chains, thus proceeding, as before, to construct another shock.
