SPECIFICATION forming part of Letters Patent No. 345,650, dated July 13, 1886. 7

Application filed February 4, 1881. Serial No. 25,377. (ModeL) To all whom it may concern: 7

Be it known that we, ALEXANDER Ross and SAMUEL J. PARKER, citizens of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in self Binding Harvesters; and we do declare the following to be a full, clear, and exact description of the invention, such as will en'- ble 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 of reference marked thereon, which form a part of this specification.

Our invention relates to self-raking and self-binding harvesters. The grain is swept heads foremost from the reaper platform or apron onto an intermediate platform,and from the intermediate platform it is pushed heads foremost by a rake into the grain-receptacle or gaveler -platform, from which it is lifted by a rake rotating intermittingly and presented to the binding mechanism,where it is bound into bundles.

Theinvention consists in the construction and combination of the several parts hereinafter fully described, and pointed out in the claims.

In the drawings, Figure 1 is a plan of a selfraking reaper and self-binding at! achment constructed in accordance with our invention. Fig. 2 is a detail plan view, on an enlarged scale, of the operating mechanism, showing the devices whereby intermittent movements are imparted to the binder mechanism, also the shifting bearing for regulating the throw of the rake. Fig. 3 is an elevation of the end of the binder attachment next to the reaperplatform. Fig. 4 is a vertical section of the binder attachment on the line 3 y, Fig. 1, looking from the outer end thereof, several of the operating parts being omitted in order that those which are shown may appear more clearly. Fig. 5 .is an elevation, partly in outline, of the inner or receiving end of the loinderattachment, showing the slotted pivoted arm and other mechanism. Fig. 6 is a front elevation of the binder attachment,showing also a small portion of the reaper-platform. Fig. 7 is a front elevation, on an enlarged scale, of the clutch on the main driving-shaft, whereby an intermittent movement of the rake and the mechanism which holds anddischarges the bundles is secured. Fig. 8 shows the same clutch in detail. Fig. 9 is a rear elevation of the binder attachment. Fig. 10 is a side elevation ofthe driving-wheel, the frame,and the 'mechanism for raising and tilting the reapermechanism shown in Fig. 13. Fig. 15 is a view of the under side of the rake and roller. Fig. 16 is an enlarged detail view showing in elevation a portion of the receiving end of the intermediate platform, the end of the strip or plate which covers the slot in said platform,an end view of the carrier to which the rake is made fast, and a portion of the bar or plate which carries lugs for supporting the roller. Fig. 17 is a front elevation of the rake and a roller with a portion of the butt-board broken away and the intermediate platform in section. Fig. 18 is a cross-sectiomcn the line we in Fig. 17, with the intermediate platform omitted. Fig. 20 shows a cam-plate fixed on the rake-shaft H. Fig. 21 is a vertical longitudinal section through the clutch which operates the rake-shaft H. Fig. 22 is a Vertical cross-section through the same on line 2 2, Fig. 21. Figs. 19, 23, and 24., show in detail the modified rake illustrated in Fig. 12.

In the accompanying drawings, A is the harvester-frame, B the binder-frame, and O the driving-wheel. A vertical bar, 0, is supported on the inner end of the axle of the drive-wheel. The upper end of this bar is above the plane of the periphery of the driving-wheel, and has affixed thereto a horizontal bar, 0 which extends over the said wheel. To this horizontal bar the drivers seat and the lifting and tilting levers O O are affixed. The tongue 0 is fixed to the vertical bar 0, near the lower end of the latter.

On the outer or left-hand end of the axle of the driving-wheel is fixed a sprocket-wheel or other suitable pulley, (1 around which runs a chain or band, 0 which actuates the main driving-shaft F on the binder-frame B hereinafter described. A guide, 0 is fixed near the top of the standard 0, and supports and holds in proper position the tilter bar or le ver D, the lower portion of which is held in the eyebolt D, which turns readily in its hearing on the vertical bar 0. The tilter-bar D is connected by a rod, D to a crank-arm extending from the fulcrum of the lever G, which is turned forward or back for the purpose of tilting the reaper-frame, as hereinafter explained.

The harvester-frame A is provided with an arm, A, arranged at its front side and projecting laterally in line with the finger-bar, the end of said arm being close to the standard C. A bracket, a, is fixed upon the inner end of the arm A, and is provided with suitable eyes or bearings adapted to hold the tilter bar or lever D. The bracket slides up and down on the tilter-lever and permits the barvester-frame to he raised or lowered by means of the lever C and the connecting chain or rod a.

The harvester-frame Aand the hinderframe B are distinct from each other, but are coupled together in such a manner that the harvesterframe can be raised or lowered or tilted at the will of the driver without disturbing the hinder-frame. They are coupled together at their rear adjacent corners by means of an eyebolt, a, and a vertical rod, a The eyebolt slides on the rod, and thus permits the raising or lowering of the harvester-frame. The rod a is braced by the rod a. The driving-wheel is arranged in front of and nearly in a line with the center of the binder-frame. A reach or arm, B is secured to the binder-frame, its forward end being provided with a hook or other means, whereby it is coupled to the standard 0. The reaper-frame and the hinder-frame are arranged in the most compact form. The binder-frame abuts against the reaper-frame. The grain is swept from the delivery side of the reaper-platform onto the receiving end of the hinderfra-me. The forward portion of the reaper-platform is extended laterally in front of the receiving end of the hinder-frame, as shown, whereby all the parts of the machine are brought into the closest relation to the driving mechanism, and are directly under the supervision of the driver. The binder-frame and its mechanism could, if desired, be detached from the reaper, and the latter could be used alone.

E is a wheel for rotating the rakes E E". It is journaled on the top of a suitable post or standard fixed on the arm A of the harvesterplatform. The rakes are raised and lowered, in the ordinary manner, by cams or inclined surfaces, and they are driven bya pinion, E, meshing with the cogs on the under side of the wheel E. To the shaft of the pinion E is attached, by a universal joint, E, the shaft E, which is connected to the main axle by means of the clutch c c and another universal joint. A coiled spring is placed around the shaft E, which spring holds the part 0" of the clutch in engagement with the part 0 The mechanism for holding and driving the rakes being supported on the arm A, is tilted or raised or lowered with the harvester-frame, and the rakes are thus always preserved in proper relative position to the cutter'har. The rakes E act as heaters to incline the grain to the sickle. The rake E sweeps the grain from the harvester-platform onto the intermediate platform, and it also engages the end of the triplever a which unlocks parts of the mechanism on the hinder-frame, as hereinafter described.

An intermediate platform, B, and a folding grain-receptacle, B", are provided on the hinder-frame B. The grain is swept heads foremost from the harvester-platform A onto the intermediate platform. A rake pushes the grain, heads foremost, into the folding grainreceptacle. From the grain receptacle the grain is lifted laterally to the hand tying mechanism. The intermediate platform, B, has a central longitudinal slot or opening, 1), extending from end to end. It also hasapinion orsmall frictionwvheel, b, journaled at the inner front corner, next the harvester-platform, as shown. The pinion b is driven by a pulley, b and a cord or belt, 1), running on a pulley, e, on the main shalt F, which drives the binding mechanism. The slot b is covered by a strip or bar, I)", which is so constructed and arranged as to have one edge secured to the platform at one side of the slot, and leave an open space between its other edge and the platform for the passage of an arm connecting the rake to the carrier, as hereinafter described. 'The rake is preferably composed of a supporting plate or bar, (1, and vertical buttboard, d. Vertical supports d are provided on the ends of the bar d, in which are bearings for thejournals of a roller, G. The roller is so arranged that its periphery is about flush with or projects slightly beyond the butthoard d, as shown in Fig. 18. On one end of the roller is fixed a gear or friction wheel, d, arranged to engage with and be revolved by the pinion or friction wheel I) when the rake is at the receiving end of the platform B. The grain, when swept from the harvesterplatform, passes over the roller, which aidsin its delivery onto the platform B in front of the rake or butt-hoard 01 The harvesterrake E will leave the grain with the butts about flush with or slightly beyond the edge of the harvester-platform. The longitudinal ribs or projections G on the roller move the grain onward over said roller until it drops with the butts lying in front of the butt-board d. The rake-carrier (1 passes down through the slot b, and is provided with guide-channels in its edges, which fit over the adjacent edges of the two parts of the platform B on opposite sides of the said slot. Its upper surface is immediately under the strip b, and it has a horizontal arm, d which projects outward through the open space between the said strip and the platform- The supporting-bar d of the rake and roller is fixed to this projecting arm. The carrier d is connected to an actuating sweep-arm, 1?, arranged below the platform B, as hereinafter described. \Vhile the grain is being swept by the rake E from the harvester-platform the rake d and the roller G will bein the position shownin Fig. 1. The roller will be rotated continuously while at this place. the rake E strikes the lever a and the mechanism for operating the rake d is thrown into gear,and the rake d is moved to the opposite end of the platform B, pushing the grain before it and delivering the same into the grainreceptacle 8*. The roller G ceases to rotate as soon as the forward motion of the rake d begins, and it supports the butts of any stalks of grain that may rise above the top of the rake d A modified rake without a roller is shown I in Figs. 12, 23, and 24. In this the rake or butt-board d is supported so that it will drop down nearly to a horizontal position at the delivery end of the reaper-platform and at the receiving end of the intermediate platform, as shown in dotted lines, Fig. 23, to permit the grain to be swept thereover by the rake E. The said rake is made of a thin board having a series of teeth on its upper edge and a notch, 8, near the middle of its lower edge. The rake is connected to the carrier d by short pivoted arms 8. A latch, s, is fixed to the carrier, and is adapted to engage in the. notch s and hold the butt-board in a vertical position. The latch is held in position by a small guide-strip, on the platform B. WVhen the rake is carriedto its starting-point,on the re ceiving end of the intermediate platform, B, the latch s" comesin contact with a small cam or projection, 8 which disengages it, and the rake then drops forward,or toward the reaper= platform,onto side rests, s, to permitthe grain to pass thereover onto the intermediate platform. The latch is thrown by the cam 8 against a small swinging lever, s, pivoted on the platform. In the outward movement of the rake the lower edge of said rake strikes the tapered end of the swinging lever s, which brings the rake to an upright or vertical position, and the lever is drawn sidewise into the notch s, and by this movement the latch s is caused to engage the rake and hold the samein its vertical position. The lever s is limited in its movements by a smallpin projecting from its lower surfacethrough asmall slot-,s formed in the platform B. In this modification the rake E carries the grain over the reciprocating rake,as the latter in its inclined or resting position extends but slightly above or is nearly on a level with the delivery side of the reaperplatform, as clearly indicated in dotted lines in Fig. 23. The teeth of the rake extend but slightly over the reaper-platform, and act, in conjunction with the side rests, s, to limit the As soon as the grain is deiivered,

.volving rake.

' the hollow hub F downward movement of the rake,thereby keeping the upper side of the same in nearly the plane ofthe reaper-platform,to permit the easy they, together with the middle section and the side sections, B B, form a semi-cylindrical grain-receptacle, the curve of which corresponds to that described by the ends-of the revolving rake-arms H, hereinafter described. The raising of the hinged sections gathers the said grain into a gavel which is lifted by the arms or teeth of the revolving rake. Transverse channels 13 are formed in the concave receptacle. These channels run with the curvature of the receptacle and correspond in number to the number of the teeth on the re-' The ends of the rake-teeth run in these channels a little below the surface of the receptacle, thereby insuring the taking up of every straw when the grain is being lifted to the binder table.

The main shaft F is journaled in hearings on the front of the binder-frame. It receives its motion by means of a sprocket-wheel, e, fixed upon it, and the chain 0, hereinbefore described. a

A clutch, F, is arranged between the end of the continuouslyrotating shaft F and the end of the shaft e of the crank e, for the purpose of securing an intermitting motion to the latter. The end of the crank-shaft e abuts against the end of the shaft F. A sleeve or hollow hub, F is fixed on the end of the shaft F, and a sprocketwheel, 6 is carried there by. An enlargement, F formed on the abutting end of the crank-shaft e fits snugly into A small disk, 6 fixed on the shaft e and against the shoulder of the enlargement F fits snugly against the end of the hub F The enlargement F of the shaft e has formed in it a longitudinal channel or groove, F, which is extended by a suitable hole through the disk 6 A clutch-pin, e", is

placed in the channel F, and its end projects through the diske and is bent to lie close against the latter, so that it will be engaged by an arm or lever, e, pivoted to the binderframe. The clutch is engaged by the edge of the pin 6 bearing against the inner surface of the sleeve F on the shaft F. The clutch-pin is so formed that it may be turned into the channel F, and so disengage the sleeve F from the enlargement F on the shaft 6 or it may be turned out, and said shafts F and e be thereby locked together, so that motion will be given to the crank e. The outer bent end of the pin is pressed by a spring, 6 by which the pin is normally held in engagement with the sleeve F "When the bent end of the pin comes in contact with the lever the pin is turned out of engagement with the sleeve F and the crank-shaft is thrown out of gear. The lever e has connected to it one end of a rod, which has its other end attached to the trip-lever a which is pivoted on the wing portion A of the harvester-platform A. The upper end of said lever is arranged to be en gaged by the rake E as the latter sweeps the grain from the harvester-platform. It is held in position by a spring, a, which throws it back to the position shown in Fig.6 whenever it is released by the rake.

The rotating shaft or rake-head H of the rake H is journaled in cross-bars on the upper part of-the binder-frame and vertically above a transverse line drawn through the middle of the grain-receptacle B and platform B. On the inner end of the shaft H there is fixed a cam-plate,-f, so constructed and arranged that in each half-revolution of said shaft it will engage and move the ends of two levers, g and g, which extend to the rear and front, respectively, of the binder-frame, where they are fixed to rock-shafts having the arms g' 9 which are connected by the links or rods B B with the lugs B B on the under side of the hinged sections B B of the grain-receptacle.

When the cam-plate moves the levers g g, the sections B B are raised into the position shown in full lines on the right and dotted lines on the left in Fig. 4, and when the cam clears the levers the sections drop to a horizontal position. The end of the shaft H projects through the cam platef, and is coupled by an interposed double clutch, H, to the shaft H of the crank H by which motion is imparted to a needle hereinafter described.

The clutch H is shown in its details of construction in Figs. 21 and 22. It is constructed as follows: A spindle or enlarged portion, H, is formed on the shaft H outside of the platef, and has made in its periphery longi-.

tudinal channels adapted to receive the halfround clutclrpinsff, passing through holes from the outer face of the plate f. A hollow sleeve, H is fixed on the end of the shaft H and fits snugly over the spindle H. The sleeve H has on its inner surface the groove X. The springsf act against the outer bent ends of the clutch-pin, so as to turn the latter into engagement with the groove X when said groove is brought into the proper position, thereby coupling together the shafts H and H The clutch-pins are turned to uncouple said shaft-s by means hereinafter described. A sprocket-wheel, h, has its hub h set loosely on the hollow sleeve H, the latter serving as a bearing for the former. The hub is held from moving laterally by the cam-platef and an annular flange or rim, H formed near the outer end of the sleeve H The inner surface or bore of the hub is pro vided with the grooves X". A half-round channel is formed in the periphery of the sleeve H, which receives a clutch-pin, f, the

end of which projects through a hole in the rim H, and is bent as shown. A spring acts against the bent end of the pinf, to keep it normally engaged with the hub h. By means of the clutch-pinf the sprocket-wheel h engages with and gives motion to the crankshaft H", and by means of the clutch'pins f the sleeve H may be coupled with the spin dle H" on the shaft H. Thus the rake-shaft H and needle-crank H may be coupled together to act simultaneously, or the crank may be revolved while the shaft H remains stationary,and both the crank H and shaft H may remain stationary by unclutching the sprocketwheel h from the sleeve H The sprocketwheel h is revolved by a chain. h, running over the sprocket-wheel e on the main shaft F. The shaft H is unclutehed at each halfevolution by turningthe two pins f, which are arranged on opposite sides of the spindle H. i is a trip-lever pivoted to the binder-frame at 2', its front end being depressed and passing under and in contact with the periphery of the disk e The said lever has ashort shoulder, i formed near its end, and is provided with a tapering extension, i. The disk 0' is provided with aseries of radial pins, 0. In the rotation of the disk the pins 0 come in contact with the extension 1' and depress the same, and thereby disengage the rear end of the triplever from the clutch-pinf. Assoon as the pins 0 clear the extension, the shoulder rises behind the last pin, as shown in Fig. 8, and

thereby the rear end of the trip-lever is made to engage the clutch-pinf The shoulder also prevents any possible reverse rotation of the disk 6 by its position behind the last pin e Instead of the pins 0', the disk 6 may be provided with a solid projection, as indicated in dotted lines in Fig. 8.

The rear end of the trip-lever i extends to the crankshaft H and is arranged to engage with the outer bent end of the semi-cylindrical clutch-pin, f, thereby turning it and disengaging the crank-shaft from the sprocketwheel h. A stop arm, i, is secured to the trip-lever i, and is extended laterally and rearward, having its end arranged in position to engage on one or the other of the pins f f, projecting from the face of the cam plate f.

The pinsf are arranged on opposite sides of the spindle H, so that the stop 1" acts to stop the shaft H at each half-revolution. The ob ject of this stopping mechanism is to insure exactness in the position of the revolving rake.

The intermittent movement of the rake H is secured by the clutch-pins ff, arranged on opposite sides of the shaft H, and engaged alternately at each halfrevolution by a curved projection or cam, i fixed upon the frame close to and parallel with the platef, and arranged so that the bent ends of the pins f pass thereunder, and are turned sufficiently to disengage them for a half-revolution from the sleeve H The pinsf during the other halfrevolution are held in engagement with the sleeve by small springs f, which press upon their outer bent ends, as shown in Fig. 20. When the sprocket-wheel h and. the sleeve H are engaged, thelatter makes one complete revolution before becoming disengaged. Durmg the first half of this revolution the springf keeps one of the pinsf engaged in the groove X; consequently the shaft H is coupled, and the rake H makes a half-revolution, bringing the-gavel up into the position for the needle to pass under it. At the end of the half-revolution the pin f comes in contact with the curved cam i and is disengaged. The other pin f is then in the position occupied by the first pin before the half'revolution, and will come into the groove by the action of its spring when ,the groove is brought opposite it by the rotation of the sleeve 11. The stop t comes into contact with one of the pins ust as the cam t disengages the pin f. The said stop is only for the purpose of aiding and supplementing the clutch-pin f, should it not act ust at the proper time, and thus stop the rake-shaft H in the proper position.

at is a slotted arm havingits lower end pivoted on the front side and inner end of the binder-frame. The wrist-pin of the crank e passes through the slot in the arm, and the latter is thereby made to swing back and forth by the revolution of the crank.

Fixed to the arm in is a pin, m, to whic the pitman m is connected. The opposite end of the pitman m is connected to the outer end of an arm, n, which is fix'ed to avertical rocking entirely to the forward end of the guide- V the various inclinations of the shaft n.

frame. By turning the rod so as to draw it toward the front of the binder-frame the space in which the box slides may be lengthened. The rod 0 has a proper front bearing on the binder-frame, and its forward end is extended within reaclrof the driver. The rock-shaft n, near its lower end, is-journaled in a rocking or pivoted box, a. The said box rocks or turns sufficiently to adapt it to the shifting of the box a on the upper 'end of the shaft. The rock-shaft n extends below the box at, and has fixed on its end a horizontal arm, towhich, at n, is pivoted the sweep-arm of, which ex tends under the intermediate platform,B, and has its end slotted to receive the pin a on the under side of the rake-carrier d By means of the pivot in the sweep-arm, where it connects with the rockshaft 12., and by its arrangement close to the lower end of the rock shaft, the said arm is held close to the under surface of, the platform B, notwithstanding The rake d withits carrier d, is moved to and fro over the intermediate platform, B,-by means of the sweep-arm u By means of the rockshaft n, carried in the pivoted bearing, the arm n and shifting box of, the movement of the rake d is regulated. The rake may be made to move the whole length of the intermediate platform, or it can be made to stop short of the delivery end thereof, at the will of the driver. The revolution of the crank e, acting upon the rod or pitman m and arm n, causes the bearing n to vibrate to and'fro, as explained. The change of the position in the rock-shaft n is shown in dotted lines, Fig. 3. The rock-shaft n and its arms a and n are so constructed and arranged that when the crank e is in the position shown inFigs. 1 and 3, with the crank-pin thereof at its extreme limit of movement to therear, the said arm n will carry the rake to the inner or receiving end of the platform B. These several parts are also so constructed and arranged that to bring the rake to the inner end of said platform the sliding box a must be at the outer end of the slot in the frame 11?. If the sliding box he held stationary at the outer end of the frame n by the set rod 0 as shown in Fig. 2, the end of the arm n will swing the entire length of the platform B, and will.

' carry the rake from the inner tothe outer or delivery end thereof. Hence when the grainstalks are short the sliding box is set and held at the outer end of the frame a, as shown in Fig. 2. \Vhen the stalks are long.the set-rod O is drawn forward more or less, according to the length of the stalks, so that the sweep-arm niand consequently the rake of, will be stopped short of the platform B, as indicated by the dotted lines in Fig. 2. By this arrangement the position in which the grain is left in the receptacle is varied according to its length,-so that the band may always be placed around it in the proper position. It may be observed that the crank ein its revolution passes above its center of motion and near the upper end of the slot in the arm m, when it removes the rake from the receiving to the discharging end of theintermediate platform, and passes under its center of motion and near the bottom of said slot and nearer the fulcrum of the arm at when it returns the rake. Hence by the revolution of the crank the rake is given a by the devices shown in Figs. 13 and 14.. A

wing or 1ug,V, having an inclined slot, V,

therein, is formed on the rear edge of the arm m. The pitman m is connected to the lug V by a suitable bearing-pin passing through the slot. The slot Vi's inclined downward away from the arm at. The pin of the pitman may be adjusted up or down inthe slot. The pitman is held in a carrier, V', which is supported by a suitable intermediate rod, a rockshaft and acrank-arm connecting with a handlevcr under the control of the driver, by which means the pitman may be raised or lowered to regulate the length of stroke of the rake. The fulllength stroke is secured when the end of the pitman is held at the upper end of the slot, and the stroke is shortened as the said end is adjusted toward the lower end of said slot.

The needle or band carrying arm S is sup ported above the grain-receptacle B. It slides between guides S Sflfixed upon the frame over the middle of and transversely to the said grain-receptacle. Its point slides immediately under the binder-table R (shown in Fig. 1) and carries the cord to the band securing mechanism. The needle receives motion from the crank H on the shaft H through the pivoted lever S and links or connecting-rods S and S". The needle moves close to the shaft H of the rake H, in order to prevent interference between the teeth of the rake and the lever S. The crank H makes one complete revolution while the rake H remains at rest, the lever S being drawn forward out of the way of said teeth both at the beginning and end of the revolution. Between the revolutions of the crank H ,and consequent reciprocations of the needle S, the shaft H and rake H make one half-revolution. This action is secured by the construction of the clutches hereinbefore described. Disks are fixed upon the rake-shaft H, and the teeth of the rake are fixed on the peripheries of these disks at points diametrically opposite, and pro ject in opposite directions in lines tangential to said disks. The two sets of teeth are thus situated in different planes, so that the set which lifts the grain will come into the same plane or flush with the binder-table R and the upper surface of the needle, and the other set, projecting toward the front of the machine, will be below the plane of the needle and the operating-lever S and out of the way of the latter in its movements to-and fro. A pawl, R, pivoted to the side of one of the arms of the binder-frame adjacent to the cam-plate f, engages one of two pins, 1', projecting from the face of the plate, and holds the rake shaft.

II against backward rotation during the twisting of the band, and serves to relieve the clutch H of the weight of the gavel when the rake-teeth, lifting the gavel, have reached a horizontal plane.

The shaft T, which operates the band securing device, is journaled on the rear side of the binder-frame and below the binder-table R, and has on its end a pinion, T, which engages with a segment-lever, p, pivoted on the binder'frame, so that it swings in a vertical plane. The lever 1) has an oval ring, 1), on its inner end, which is placed around the crank-shaft H This lever is given its motion by ashoulder or pin, p fixed on the inner side of the crank H". The ring 1) has in its outer end a small notch, 1;, into which the shoulder or pin p will enter at the proper moment, and by positive action lift the ring, and thereby depress the segment 1) of the lever 11. The segment p rotates the pinion T and shaft T at the proper moment for securing the band. The segment-lever p, shaft T, and needle S are operated in the proper relative times by the crank H. By having the shaft T and needle operated by the single crank no mistakes can occur in the process of securing the band.

K is a head-board hinged to the outer end of the binder-frame, for the purpose of extending the platform B" when the grain is long. It also serves as a stop to prevent short and light grain from being thrown off the said platform. \Vhen long grain is being cut, the said board is let down to ahorizontal position, or to any angle between the vertical and horizontal. \rVith short grain it is set in a vertical position, and stands against the end of the grain-receptacle. It may be of any desired width.

tis a curved wing or apron hinged to the rear end of the divider, sothat it will turn outward over the reaper-platform A into line with the divider, as shown in dotted lines in Fig. 1. It is pressed outward into said position by a spring, t, fixed on the divider. It is pressed back by the inner tooth of the sweep-rake E, when it will fill the space between the rear edge or end of the divider and the end of the front board on the binder-frame, thus making a continuous shield from the reaperframe to the binder-frame. When the rake E has delivered the grain to the intermediate platform, the wing is returned by the spring into the position indicated in dotted lines, in which position it causes the grain cut by the inner end of the sickle to fall back onto the platform at rightangles to the sickle.

A further part of the invention consists in a device for discharging the bundle or throwing it off the bi ndertable after the band is secured. This device is shown attached to the binder in Figs. 1, 3, 5, 9, and 13. It consists in a rockshaft, L, supported in bearings on the rear side of the binder, and provided with two series of radial fingers, Z and Z, arranged at or nearly at right angles to each other. The bandle while being bound is held between these two series of fingers. The rock-shaft L lies parallel and close to the binder-table R. and the front or lower series of the fingers Z extend across and lie in transverse grooves or channels formed in said table. The other series of fingers, Z, stand in a vertical position, as shown. The end of the rock-shaft L is provided with a crank-arm, which is connected by a pitman, L", to the swinging arm m. The pitman rocks the shaft about one-third of a revolution, which carries the fingers Z Z sufficiently far to the rear to drop the bound bundle to the ground. On the needle S is fixed a vertical compressing-arm, S, rising from near the eye thereof,and so placed that it will push the bundle onto the binder-table and over the twister, and compress it against the vertical but it is preferably used therewith, as better results are obtained. The supporting fingers Z could be dispensed with. If not used, the tension of the band will be sufficient in all ordinary cases to hold the bundle in place. The supporting fingers, however are preferably used, for by their use all possibility of mistake in binding is prevented, and in case a band breaks the grain will be held together.-

The following is a detail statement of the several steps in the operation of binding a bundle. A sufficient quantity of grain having been cut and deposited upon the reaper" platform, it is swept off heads foremost by the sweep-rake E, and by the roller G it is raised and carried over and deposited beyond the rake and butt-board 01. At this point the rake E strikes the trip-lever a and thereby disengages the arm a from the clutchpin e of the clutch F. The spring '6 at once throws said pin into engagement with the main shaft F, and the shaft 6 is thus locked to said shaft F, the crank e is revolved, and the rake d acting against the butts, pushes the grain, heads foremost, into the grain-receptacle B, and is at once returned to the receiving end of the platform 13'. The clutch-pin then comes in contact with the arm 0, and the clutch F is disengaged from the shaft F and the revolution of the crank e is stopped. Just after the rake d begins to return to the receiving end of the platform B the pins e e on the disk 6 press down the forward end of the lever 1', thus raising the rear end thereof, and thereby disengaging the latter from the clutchpinf in the clutch H, and the crank-shaft H at once becomes engaged with the sprocketwheel h and the needle is withdrawn. At the same time the stop-arm i" is raised from the stop-pin f on the cam' plate f, and when, by the rotation of the crank-shaft H the notch X corresponds with the pin f, the latter is turned by its spring into engagement with the said notch, and the rakeshaft ll becomes engaged with the sprocketwheel h and the rake H makes one half-revolution, bringing the gavel up against the cord, which extends from the band-securing mechanism to the eye of the needle,which is now moving across toward the binder-table to carrythe band under the gavel. This takes place immediately after the sections 13 B of the grain-receptacle have been raised by the ac tion of the cam-plate f. By the rotation of the shaft H and crank H? the needle is carried across to the binder-table,earrying the band around the gavel and bringing it alongside of the old end in the band securing mech anism. The scgment-leverp acts immediately after the needle passes across to the bindertable, and revolves the twister-shaft and secures the band before the needle returns to its first position. The bound bundle is discharged as soon as the crank 0* beginsto revolve to opcrate the rake d in the operation of carrying a new gavel from the reaper-platform.
