GRAIN-BINDER.

SPEIFICATION forming part of Letters Patent No. 274,441, dated March 20, 1883.

Application filed October 152, 1882.

To all whom -t't mrt-y concern Be it known that I, JOHN S. DAVIS, of 'Ioledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Grain-Binders, ot' whichthe following is a spccitication.

My invention relates to, improvements applicable to grain-binding machines ot' the class usually designated platform-binders-that is, machines by which the grain is delivered i n or nearly in horizontal paths from the grainplatt'orms to low-down binding-receptacles.Y

My objects ch'iey are to insure isolation or cornpiete separation ot' the respective gavels ot' grain successively accumulated for binding from other grain carried by the machine, so preventing the entanglement; or connection by straggling stalks of one bundle with another, and to insure the-delivery of' grain to the binding-receptacle in properly straightened and even condition.

The subject-matter deemed novel will hereinafter he distinctly claimed after being dcscribed in connection with the accompanying drawings, which represent a suitable application of my improvements, though showingonly those parts Ot' appropriate mechanism an` illustration of which is thought to be required to convey a proper understanding of my improvements. Some of these improvements may, however, be used without the others, and also be employed in connection with mechanism (littering in various respect-s from that shown and hereinafter particularly described.

Figure l is a plan view, parts heilig broken away and various features ot' a complete machine Omitted. Fig. 2 is a view partly in rear elevation and partlyin section on or about on the lines 2 2 ot' Figs. 1 and 4. Fien?, is a view partly in rear elevation and partly in section on the lines 3 3 ot' Figs. 1 and 11. Fig. et is a side elevatiou. Fig. 5 is a view partly iii-pian and partly in section, as indicated by the lines 5 5 of Figs and 10, showing on an enlarged scale a portion of the gear-plateior gearingsupporting front end of the binder-fraaie, and in partt-he mechanism mounted thereon. Fi. (i is a detail view, partly in plan and partly in section, throughthe gear-plate on the line 6 (i ot' Fig. 7, showing parts of tripping meehanism through or by way of' which a cut-ott',

gavel-scparating mechanism, and` binding mechanism are thrown into action bythe pressthe tripping mechanism. Fig. I() is a view in elevation with some parts in section, showing the inner side ot' thc binder-gear or main gear by which the bindcrarm, knotter, Sac., (the binding mechanism proper,) are actuated, the devices by which the knetter-pinion is actuated heilig omitted. Fig. i1 is a view partly in front elevation andpartly in section on the line 11 11 of Fig. 5, showing details of the tripping mechanism and means by which part-s thereof are held against accidental movement.

Fig. 12 is a view showing in longitudinal section a portion of the driving-roller of the endless earrier. Fig. 13'is a rear elevation of a portion of the grain-platform, Ste., showing means for adjusting a series Ot' rocking tingers by which the grain is straightened on the cndless carrier.

-As in this instance organized, my present improvements are espccialiy adapted for use in connection with sundry other improvements invented by me and shown in my applications y Nos. 70,814 and 71,887,1or United States Letters Patent for Improvements in Grain-Binding I'Iarvesters7 and Improvements in Band- Securing Mechanism of Grain Binders, rcspcctiveiy tiled September 1, 1882, and Septcmber15,1882. Otherfeatures,somcof'which are sho-wn iu connection with my present invention, and in connection vwith some of which my invention is suited to be used when ingrafted upon a fully -organized machine, are the same or substantially the same as devices or combinations ot' mechanism shown and dethe improvements claimed by me in United States Letters Patent No. 260,668, of July 4, 1882, and Nos. 261,59() and 261,591, Ot' July 25, 1882.

I do not herein claim any improvement claimed or claimablc in either of the aforesaid 'scribed in connection with or as constituting IOO applications, my present invention being limited to certain improvements herein claimed.

The finger-beam A, the grain-platform provided with a series of belts, constituting an endless carrier, A', the circular rotary buttguide A2, the platform back beam A3, the binder gearing and manner of actuating it, and the sills B B, gear plate B', cross-bar or tie-piece B2, tubular framesupport B3, and spanner pieces or bridge bars B4 of a light binder-frame, are, unless hereinafter otherwise described, all the same or substantially `the same as heretofore elsewhere described by me. The cross-ribs or transverse cleats, commonly attached to endless carriers, are by preference omitted from the belts of the carrier A, in order that the movement therewith of the grain toward the place of delivery or binding-receptacle A4 may the more readily becontrolled or temporarily arrested for straightening, in manner presently to be described, as well as for insuring its being properlyevened at the butts by the action of the butt-guide.

The -mechanism for impeding or arresting the stalks of grain in their travel Wi th the carrier is adjustable, so as to best suit it for action in straightening the grain in the varying conditions in which it is deposited upon the carrier as cut, as well as to provide for holding it out of action when the grain does not require straightening. Thisstraighteuingmechanism, as shown, consists of a series of short vertically-rockin g tin gers, C, secured to a rockshaft, C', suitably mounted in the finger-beam and platform back-beam and extending between the upper and lower portionsof the carrier, the fingers projecting' through the spaces between the belts when set for action by a lever or crank, C2, at the rear end of the rockshaft. A rack, G3, on the back-'beam engages with the lever to hold the straightening fingers in the desired positioneither out of acf tion beneath the upper part of the carrier, or projecting more or less through the spaces between the carrier-belts. The fingers are preferably hooked or curv'ed downwardly at their outer ends, with their rangeof adjustment such as never to admit of their points rising above the plane of the carriers upper surface, for an obvious purpose. It will be understood that when the straightening-fingers are rocked into operative position, as shown, those ends of stalks of graineither the heads or the buttswhich are in advance or nearer the delivery end of the carrier than their opposite ends (a condition arising principally from the irregular way in which fallen or inclined grain is necessarily deposited upon the carrier at varying inclinations, instead of at right an gles With the finger-beam) will be arrested in their movement with the belts and held by the lingers until the rearmost ends are brought up, and the stalks thus caused to lie diametrically across the carrier from its front toits rearedge, or parallel with the rock-shaft of the straightener. As the stalks are thus accumulated they are in turn gradually raised and forced over the fingers, and while so accumulating they are acted upon by the butt-guide to even the grain at the butts.

The carrier drivin g-roller is actuated continuously,during the rotation of a driving-gear, D, by means of a pinion fast on the shaft c of the roller and engagedby this gear. The 'drivingroller ofthe continuously-actuated endless carrier is made in sections, bei-ng composed of a series of short Wooden rolls or spools, b, corresponding in number with the belts making up the carrier and fitted and clamped upon the shaft c, so as to be held by friction against turning independently thereof. 'lhe front or first one ofthe series of rolls is abutted against a plain metallic disk, b', which is tted on the shaft and held against forward movementthereon by a cross-pin, c', or by some wellknown equivalent for the pin. The diskvis ofa diameter sufficiently greater than that of the roller proper to act as a belt-guard. Another disk b is interposed between the rear end of the iirst roll and the adjacent end of the next roll, and serves as a guard against displacement of the belts between Whichit projects. Gentrally and annularly shouldered or hubbed disks a2 are arranged in `pairs uponthe shaft between the respectively adjacent ends of the remaining spools b, and at the rear end of the roller a shorter spool, b2, abuts at its front end against the rearmost one of the last pair of disks a?, and at its rear end is borne against by a disk or washer, b3. A nut, as, screwed upon the threaded p'ortion a4 of the shaft, near its rear end, is forced tightly against the washer-disk b3, thus sufficiently rmlyclamping all the parts together, as lWell as upon the shaft, the frictional contact between the pin a and front disk b and the nut a3 and washer b3 holding the roller to the shaft. The reduced or tenoned rear endof-the shafta is fitted in a thimble bearing or bushing, b4, in the back-beam of the platform. rlhe plain surfaces of each pair of the hubhed-disks are placed next the'adjacent ends Of the spools, between which they are located, and their hubs abutted, so forming annular spaces between the disks from their hubs to their peripheries, for a purpose further on to be explained. Instead of' the pairs of disks a?, one-part annularly-grooved circular plates might be used, if preferred.

A cut-olf, shown as consisting of arock-shaft, c, having fingers c rigidly connected to it, and a crank, c2, is intermittingly actuated by suitable mechanism, through or by Wayof a link or connecting-rod, as will hereinafter be described, so as to arrest'the liow of grain when a sufficient quantity to form a gavel has acoumulated in the binding-receptacle, or in it and between it and the carrierin the way E, along which the grain passes from the carrier to the binding-receptacle. The upwardly-curved fingers of this platform cut-off rest at their ends, when out of action, in the annular recesses provided in the carrier driving-roller by the IOO IIO

' clutch mechanism for binding a gavel, the trip' pairs of hubbed disks, and are connected with the rock-shaft by means of short arms or crankpla-tes c3, tired to the rock-shaft and having the lingers rigidly united to them by riveting 0r otherwise. When elevated each cutoff finger, except the rearuiost one, projects through a space between the adjacent edges of two car- 1ier-belts,and the rear iinger rocks up nea-r the rear edge ot' the back belt of the carrier. No cut-oft' finger is shown between the first and second belts of the series; but one may be employed there, if preferred, and a pair of disks, a2 cor the equivalent-a single grooved disk-ivould ihen be substituted for the disk b'. No entoil' is employed in advance of the front belt, the butts of the grain not extending so t'ar forward after being acted upon by the butt-guide. By curving the cut-ott fingers and mounting them by cranks on the rockshat't, as shown, it will be seen that the fingers, when raised, pierce through instead of lifting the mass of grain that provision is made for arresting agreaterquai'itityof grain than could he stopped by straight lingers projecting a corresponding distance above the carrier; that the fingers` are not apt to draw stalks between the belts in descending, and that the grain isaccumulated against the fingers closer to the inner end ofthe carrier than it would be were the lingers attached directly to the rock-shaft instead of to the crank-plates. It will further be apparent that in event ot' injury to the fingers they can be removed by separating them from the crank-plates and necessary repairs be made without loss of the crank-plates or even removing them from the rock-shaft.

The driving-gear D ot' the binder-,gearing rotates with the bevel-pinion d, which is actuated in any suitable way, preferably as shown in the helb're-referred-to application, No. 70,814, of September l, 1882.4 An idle-pinion, d', to which motion is imparted by the driving-gear, meshes with a gear, D', which is fastened on the shaitd2 ot' a packer, D2, and serves to rotate the shaft and operate the packer continuously during the actuation of the driving-gear. A pinion, d3, attached to the gear D' on the packer-shaft, meshes with a gear, D3. for in` termittingly actuating a normally stationary gear, D4, by the mechanism ot' which the bind ing mechanism is actuated.

The binder-gear D4, as heretofore fully described in connect-ion with other ot my inventions, ma kes one revolution each time it is thrown into action by suitable tripping and ping mechanism being actuated by the pressnrc exerted by the grain, and serving by its connections with the clutch mechanism to cause tem porary engagement ofthe binder-gear ywith its actuating-gear D3.

The gear D3 is unprovided withtheheretofore employed face-spurs or side teeth for engagement with the sliding clutch-bolt F of the binder-gear, this bolt being caused to engage, when slid outward, with the ordinary peripheral teeth of thev gear D3. In other respectsy the clutch mechanism (including the means for dogging and for retracting the bolt F) is the same as before, consisting of the tripping and 'clogging lever F', acted upon by a spring, and` provided with the catch j', the spring f', the lever F2, pivoted on the binder-gear, and connected at one end with the clutch-bolt and acted upon at its opposite end by the catch end of the lever F', and the lixed cam f2 on the frame or gear-plate B', acting on the bol t-lever, and by which the bolt is retracted against the force of the spring f', and its lever left engaged by the dogging and tripping lever.

A rock-shaft, G, means by which to operate it by the pressure exerted by the grain when accumulated to form a bundle, and connectA ing mechanism between the rock-shaft and lcver F', serve, as fu rther on to be described, to

retracted, the binder-gear is locked against" accidental movement by the spring-brake F3 yieldingly engaging with it.

The binder-arm rock-shaft H has the roek- -ing binder-arm H' fastened to it, is mounted in the rear bearing, It, and the frame-tube B3, and is actuated by a slotted crank, h', and a pitm an, H2, connecting it with the bindengear in suoli Way that it may be held at rest, as heretofore, While bands are being knotted about bundles. A

The arms of the packer rotate in lon gitudinal openings or slots in clca-rers E E', which not only'servc to strip from the packer any grain which may cling to it, but also partly constitute the bindingreceptacle A4 and grain passage-Way E, leading thereto from the grain platform. Each of these clearcrs is pvotally supported at one end on the packer-shalt by a pair of lugged sleeves, e, at the sides of' the hub of a set of packer-arms, and at their opposite ends the clearers are adjustablysecured to the binder-arm rock-shaft and to the frame-tube B3, respectively. so that the clearers, after being slightly rocked about the packer-shaft to raise or lower them, maybe held in the desired position.

The rock-shaft G of the automatic tripping or starting mechanism is mounted in bearinglugs g g' on the frametubc B3, and, as in this instance shown, is operated by a float-trip or vertically-vibrating starting-arm, G', elevated by the upward pressure ot' the grain as accumulated in the receptacle beneath it. The starting-arm, as shown, is mounted at its heel end, so as to rock freely aboutthc packer-shaft d2, by means ot' a sleeve, g2, and at its outer forked end acts upon the tripping rock-shaft G. This rock-shaft is shown as provided With a crank or toe, G", to be struck and elevated by the starting-arm, the fork gu at the free end of which engages the toe and insures proper ac- ICO tion when the farm is forced upward by the grain. The toe G2 is by preference adjustably secured to the rock-shaft to admit of its being set, so thatthe proper rocking movement may be imparted to the rock-shaft bythe startingarm when raised to any desired extent by the grain, the rock-shaft being so adapted to be actuated by larger or smaller gavels, according to the size which it may be desired to have the bundles when bound.

Mechanism by which to separate grain for forming a bundle from other grain, andinsure its delivery to the binding-receptacle or within the embrace of the binder-arm, and then completely isolate it to render it impossible for grain of one gavel to become entangled with thatofanother, consists,asin thisinstance shown, of the following devices: Two rocking partingarmsf7 I l, are loosely mounted upon the packer-shaft d2 by means of arsleeve, e', to which they are rigidly connected, and this sleeve is provided with a rack-gear, e2, which is engaged by a rack-bar, I', having suitable pivotal connection, t", at its heel end with the binder-arm near the heel end or rockshai't H thereof. A guideway formed by a' lugJ', on one of the clearer-supporting sleeves e holds the rack-bar in engagement with the gear e2. Each of the parting-arms has an irregularly-curved rod, 12, secured to it, one end of the rod being fastened to the point or extreme outer end of the arm, and the other end secured to the arm near the heel thereof or close to the packer-shaft. The curvature of these rods 12 12 is such that they do not project into or obstruct the biinling-receptacle, and do not, when in their normal position, interfere with the passage of the grain along the way E as acted upon bythe arms of the packer D2. The parting-arms are of equal length, and are longerthan the arms of the packer, andthe radius of curvature of each of the rods 12 for a portionsay half-of its length about corresponds with the length of the partingarms, these portions of the rods being concentric with the packer-shaft. For the remainder oftheir length the rods are eccentric, gradually nearing the packer-shaft. It will thus be seen that the rods 12 12 for a portionsay two-thirds-oftheirlength are farther from the packer-shaft than are the outer ends of the packer-arms. The rods are in this way made to act as a guard or auxiliary cut-off to prevent any grain being forced toward the binding-receptacle or acted upon by the packer when the parting-arms have been moved by the downward rock of the binder-arm into position such or about such as that in which one of them is represented by the dotted lines in Fig. 2. As the packer-arms rotate above the bottom of the way E, and within the path described by the outer end of theparting-arms, and as these arms in descending approach very closely to the endless carrier where it passes over the driving-roller to reach grain outside the path of the packer, and then project into A t amaai the slot E2 in the bottom of the grain passageway, so as to interpose the passage-way cutoft' or packer-guard 12 between the carrier and the packer and passa ge-way, while projecting beneath the bottom of the passage-way`,'it will be seen that grain left by the packer will be acted on by the arms, and that there is no possibility of carrying grain from the platform or carrier to or partly to the binding-receptacle, even were any straggling stalksleft inside the roller of the endless carrier or inside the platform cut-off or rocking fingers c when elevated.

Instead of the gavel-separating mechanism consisting ofa pair ofparting-arms and their attached guard-rods, a single arm and guard-rod may be used, ifpreferred. This gavelseparating mechanism, as in this instance shown, is thrown in to action afterthe elevation ofthe platform cut-off fingers c', in order not only to give the packertime to clear the way E, but that by -said mechanism any grain inside these fingers,

within reach of the parting-arms, which has not been carried along and forced in to the binding-receptacle by the packer shall be delivered' to the receptacle and held so as to be brought within the embrace ofthe binder arm.

Those features of the tripping and starting mechanism which actuate the cut-off to arrest the delivery of grain by the carrier preparaand carriesc a latch, K, Iacting in connection with an arm, L, hung loosely on the shaft G at its end. The latch consists of a verticallyvibrating arm connected at its heel by a pivot, k, to the arm J2 of the crank-plate, and supported at its opposite end by a pin, k', inja curved slot, K', in the arm J' ofthe crank-plate. The loosely-mounted arm L is acted upon by the latch so as to be engaged and caused to swing with it until freed by the upward movement ofthe latch.` The latch and arm are engaged by the Contact of a clogging-shoulder, l, on the former, with a lug, L', on the latter. The latch is provided with a trip-lug, L', by whichit is elevated to free the arm L, as in turn to'be explained. 1t will be seen that so long as the pendent arm L on the rock-shaft G is dogged by the latch of the crankplate J the arm is caused to swing with and maintain a fixed relation tothe rock-shaft when acted upon as before explained, and that as soon as the latch is tripped to release'the arm it is freed from control by the rock-shaft and its attachments.

The rock-shaft G is connected witha spring- ILO lIO

IIS

actuated dog or hook-ended bell-crank lever, M, mounted in bearings shown as formed by the supporting-lugs in m', projecting rearwardly from the gear-plate portion B of the binderframe, and performing functions in turn to be explained. The connection of the rock-shaft with said dog is through or by way of the arm L, and a link or draw-bar, L2, pivoted at its opposite ends, respectively, to this arm and the controlling-arm M' of the dog. rthe dog has two motions, being adapted to rock vertically and vibrate in a plane at a right angle with that in which it rocks. The vibratory movement of the dog is substantially horizontal. This twomotion dog has formed with or rigidly attached to it a sleeve orlong hub, M2, and the pivot-piii-m2 is fitted in this sleeve and iixedly fastened thereto by a removable pin,

or otherwise, when the parts are in place in the bearing-lugs. The upper one, m, of these lugs is slotted, and the pivot-pin is so formed and fitted in the lower lng, m', as to admit of the desired slight rocking motion, the upper end of the pivot4 playing in its bearing-slot to `accommodate this motion. Asprin g, M3, coiled about the dog-sleeve, bears at its opposite ends, respectively, against a fixed lug, m3, (seen dotted in place in Fig. 5,) and a pin, m4, on the dog, and is thus made double-acting, one of its functions being to hold the dog rocked downward to the limit of its movement, or act with a tendency to move it into this position, as shown, and the other to act in opposition to the link L2, (and another link further on described,) and hold the dog in its normal position, when the dog is freed from other control, and vibrate it into such position when released after bein g positively vibrated in the opposite direction.

An intermittingly-actnated mutilated gear, N, loosely mounted on'its shaft-in this instance the packer-shaft dtv-has a verticallyricking pawl, n, pivoted to its inner face, or that next the gear-plate B', and a' ratchet, N', is fastened to the shaft, close to the mutilated gear, for engagement with the pawl when this gear is to be caused to rotate with its shaft.

The pawl a (see Figs. 3 and 1l) is pivoted about midway itslength to the gear N, near its periphery, is provided with the usual ratchet-engaging nose, is borne against at its heel end by a spring, a', acting with a tendency to rock the pawi-nose into engagement with the ratchet or hold it engaged therewith, and has a heel arm or hook, n2,- normally engaged by the hook or nose ot' the dog M. The strength of the spring M3 is such relatively to that of the spring n as to enable the dog to overcome the force exerted by the spring n' on the pa-wl. In this way the weaker spring, while serving to hold the pawl engaged with the ratchet when the dog is vibrated and the pawl released, is caused to yield to the force exerted by the stronger spring when the pawl is dogged or held in its inoperative position by the dog. The gear N makes one revolution at lated teeth of the pinion.

ging-arm or spring-brake, q, serves to arrest each actnation,'and when, upon the final portion of its revolution, the pawl is presented to thedog-nose, the dog, by the contact ofits nose with the pawl between its pivot and heel, is rocked upward against the force ofits springMS, into the position in which it is represented by dotted lines in Fig. 11. When the dog is so rocked upward its pivot m2 is moved in the slot in the bearing m, and comes to rest at the end of the slot opposite that which itis shown as occupying in the drawings. This movement of the dog to the limit of its upward rock is the result of the resistance offered to the upward rock of the pawl-nose arising from thebinding contact of the nose with the ratchet and the force exerted by the spring a', as well as by the considerably decreased force at first exerted by the dog upon the pawl because ot' the difference in leverage when the pawl is acted upon at its heel and between its heel and pivot. The dog-nose, acting upon the properly inclined or curved portion of the pawl from or near its pivot to its heel, gradually lifts the pawl-nose, clearing' it from the ratchet at the proper time. Immediately upon the release of the ratchet the force of the spring M3 overcomes that of the pawl-spring, and the pawl-nose is lifted well clear ofthe ratchet as the dogpivot moves at its upper end' in the slotted bearing in, thus rocking down the dog-nose. In this way wear, noise, and possibility of accidental engagement of the pawl and ratchet are prevented. The gear N actnatcs a mutilated pinion, 0, which' is given a halrevolntion at each actuation. This pinion is suitably connected by a rod or pitman, P, with the crank of the cut-off rockshaft e, and serves by one actuation to elevate the cutoff lingers c' into their operative position (seen dotted in place in Fig. 2)-and by the next actuation to depress these fingers. The pinion has two regularlyformed groups of teeth, O' 02, corresponding with the group of teeth P' of the gear N, and has two isolated teeth, o o', each vseparated at both sides from the teeth O' O'2 by spaces corresponding with the space between the teeth P' and the isolated tooth p of the gear N. When the pinion and gear are at rest, the isolated gear-tooth p is in contact with or close to one of the-iso- A yielding dogthe pinion when released by the gear N, and

hold it against accidental movement. The dog-arm is fastened to the gear-plate B', vis angnlarly bent at its outer end, and engages with one or other oftwo notches, q' q', in a plate or disk, Q,fastened to the hub or sleeve of the pinion 0, which turns about a suitable support secured to the gear-plate.

In order that the binding mechanism shall be thrown into action subsequently to the time of elevating thecut-oli', while it is retained in its elevated position, and by the operation of the above-described actuating mechanism of the cut-oli', the gear N and pinion O ot' this 6 g Q'WLLLU.

The connecting mechanism actuated by thegear N and pinion O comprises a thrust-bar, It, acted upon by a lug, non the gear N,

and a rod or link, It', connected at one end with the crank or wrist-pin r' of the pinion O, and at its opposite end with aloosely-hung swinging arm or crank, S, by being jointed outside the thrust-bar to the crank-pin s, which passes through a slot, S', in the thrust-bar. This swinging arm S supports one end of the thrust-bar, and is hung upon a stud on a bracket, S2, attached to the gear-plate by a bolt, s2, which serves also to secure in place the tubular stud-shaft of the gear D3. The opposite end of the thrust-bar is supported and guided in its reciprocations by a loop-bracket or slotted arm, S3, bolted to the gear-plate.

The latch K is tripped by the action of an incline, R2, of the thrust-bar on the trip-lug L', the outer end of the latch being lifted sufficiently when actuated by the thrust-bar to release the arm L, whichy immediately swings into its normal position as acted upon bythe spring of the dog M through the connectingrod L2, as this dog moves into its normal position. When the thrust-bar is in its normal or retracted position its inner or lower end is beneath the path of the striker-lug fr,- but when, upon an actuation of the gear N, the pinion O is given a half-revolution to elevate the cut-oft' and cause the link R to swing the supporting-arm S, the lower end of the thrustbar is lifted into position to be actedlupon by the lug r near the completion of the revolution of the gear N, and is forced at its upper end against the lever F', so vibrating this 1ever against the force of its spring j' to trip the binder-gear clutch. At the same time the swinging arm L is undogged by the tripping of the latch K. Obviously the slot S' of the thrust-bar must be made long enough to admit of the thrust-bar being moved by the action of the lug r a distance somewhat greater than that between the upper end of the thrust-bar and the lever Il", and as this movement of the thrust-bar takes place when the crank-pin s occupies the position to which it is moved by the pull on the rod R', by the actuation of the pinion O to lift the thrust-bar, the slot must be of a length about twice as great as the distance between the axes of the pinion O and wrist-pin r', plus the space occupied by the crank-pin, the distance between the lever F' and the upper end of the thrust-bar, and the distance the thrust-bar has to move after striking the lever to properly actuate it. After being actuated by the lug on the gear N the thrust-bar, owing to itsinclination, would naturally slide by gravity into its normal position.l

Its restoration to this position is, however,-insured by the action of the spring-actuated lever F', which, by pressing against the e'nd of the thrust-bar, starts it and imparts to it a downward impetus. Owing to gravity and the jolting of the machine, the thrustbar moves downward or. toward the gea-r N when the lower end of the thrust-bar is lifted by the crank-pin. the thrust-bar to move toward the gearNwith the crank-pin in time to have the upper end of the slot occupied by the crank-pin when the lug r acts would not affect the operation of the thrust-bar upon the latch K and lever F' otherwise than to lessen the movement of the bar in performing its office. 1t' should be noticed that immediately upon starting the gear N operates the cut-off-actuating pinion, and that the cut-off is completely elevated before the gear has made one-fourth of its turn, while the thrust-'bar is not acted upon until the gear has very nearly completed its revolution. In this way the packer D2 acts upon the grain within its reach inside the cut-off and delivers it to the binding-receptacle before the actuation of the gavel-separating mechanism or the descent of the binder-arm. Any stra ggling stalks which may be left undelivered by the packer are forced into the receptacle by the parting-arms I I, when rocked downward and into the position which they are caused to assume when holding the delivered grain against spreading by expansion of the compressed gavel outside the path of the binderarm nose. The cut-off is restored to its depressed or normal position by a second actuation of the gear N, when the dog M is tripped to free the pawl a by secondary mechanism, as follows: An inclined linkor draw-rod, T, connects at one end with the arm M', near the point of attachment thereto of the link L2, is

Obviously, ,however,.a failure. of f IOO provided with a hook, t, at its opposite end,

gear (the actuator of the binding mechanism) actuates'the link T by connecting mechanism, which serves also to actuate arocking arm, constitutin g a grain-retainer, gavel-compressor, and bundle-discharged@ fast on a rock-shaft, U'. In most respects the rocking arm U, shaft U-, andthe actuating mechanism thereof are the same as elsewhere shownI and claimed by me, and to the extent so shown and claimed are not herein claimed. vA crank or disk, T', fast on the rock-shaft U', isA provided with a striker-stud or side pin, t', for engaging the hook of the link T. At the proper time the disk T' is rocked with its shaft to cause the pin t' to act on the link and trip the dog M,s o

lamai-n 7 way and thereceptacle cleared of a bound bundle, grain for anotherbuudle will be directed tothe receptacle along the way E, after the downward rock-of the cut-oft by the pull on the connecting-rod P as the pinion O makes a half-turn. The binder-gear, when first started, acts by a long edge rib or side flange, T2, Fig. 10, upon the stem orleverend u of a segmentgear, u', fast to the shaft U', and moves the lever from the normal position l into position 2, as shown by dotted lines. rlhe corresponding,l slightinward movement of the compressor end ot' the arm U compacts the gavel and improves its shape while the binder-arm is descending` and drawing' the binding material tightly about the grain. The rib T2 acts on the rock-shaft lever u ior the greater portion of the time occupied during the descent of the binder-arm, releasiig the lever in time to relieve the binding-arm oftoo great strain when about to be locked in the knotting position and while in contact with the grain. While the knot is being tied, preferably by a vibrating knetter, such as elsewhere described and claimed by me, the compressor is again actuated by the.

rocket' the lever @from the position in `which it-is shown by full lilies to the third positionnearly the same as that above designated position 2-as shown at 3 by dotted lines. The cam-ended rib or iiangeU'z gradually forces the lever to this position, and thus provides snilicient slack in the band about the bundle for properly forming a knot, as elsewherefully described by me. The movement to brine; the lever u into position 4 (shown by dotted lines) is imparted by the segment-gear V, and serves to actua-te the link T, with the result already fully explained, and to discharge the bound bundle, as will readily be understood. The action of the rib T2 upon the lever n imparts the tinal movement to the lever to restore it to its normal position atthe completion of a revolution of the-binder-gear. While the knot is beingl tied in the band about a bundle the binder-arm is locked at its nose by the engage.- nxent with the shoulder to' of a yieldinglymounted"dog,uf,on arock-sbaft, W. The rockshalt U', when in its normal position,is dogged by an arm, V', on the rock-shaft W, acting;` against a shoulder, o', on a disk, W', secured to the shaft U. A crank-arm, Y, on the end of the dogging-shaft X'V, is acted upon at the proper time by a rib, y, on the outer face of the binder-gear, so as to rock this shaft against the loreeot' its spring Y', and so release the binder-arm and the rock-shaft U', preparatory to the actuation ot' the latter by the segment on the binl'ler-gear.

f The dogging mechanism just above described is shown, fully described, and claimed elsewhere by me, and is not therefore herein claimedby itselt'cr otherwise than in dilterent combinations or connections not heretofore shown.

The actuating mechanism of the knotter, consisting in part of the-pinion Z on the knotter-shaft and the segment-gear Z' on the binder-gear, needs no description here, as this mechanism is elsewhere shown and claimed, and is not herein claimed.

When the machine is in operation, as will readily be understood from the above description and the drawings, a double precaution is taken-(by the employment ot' the platform'cutoff actuated before the starting' of the binding mechanism and by the. parting-arms) against the delivery of grain to the passage Way or to the action of the packer after the binding mechanism is started, while the still further precaution taken by the employment of the packerguarding and passage way cut ott' mechanism prevents the carrying,` along the passage-way ot' any slightly delayed or temporarily lodged or entangled stalks which may have escaped or resisted the action ot' the packer and parting arms. The tying; together of bundles by connecting stalks, and the consequent injurious et't'ects-such as dragging of bundles over the stubble, loss of grain, derangement of bundles, or breaking ot' bandsare by my improvements rendered impossible.

I claim as of my inventionl.
