BERRY sIIocKER INCORPORATED, or on DELAWARE.

WILMINGTON, DELAWARE, A' coRPoRA'rIoN GRAIN sHooKER.

The shocker of the present invention is of the general type shown and described in the Bert C. Berry applications, Serial No. 318,- 738, iled August 20, 1919, and Serial No. 446,843, tiled January 8, 1921; and the present invention is directed to numerous features of improvement in the structure and operation or the various working part-s included in a shocker of the type indicated.

The grain shocker oit ploys an open sided pan or sheaf receiver, into which the sheaves are dropped from the binder with which the shocker is associated. The sheaves fall into the pan with their butts projecting forward and accumulate in the pan until the number required to constitute a shock has been accumulated. At this point trip mechanism is operated which drops the pan until the tread members with vhich the pan is combined engage the ground, after which a complete rotation of the pan is effected, upending or butting the shock upon the ground, and causing the pan to somersault over the top ot' the shock in its return to normal or receiving position.

The pan and tread membersare carried by a pivoted inner frame, and these elements in combination constitute in effect a dump cart, which in depositing the shock iunctions in a measure independently of the tour wheeled frame, which constitutes the supporting element for the pan and tread members while the shock is being accumulated.

llie present invention is directed to the toll owing instrumentalities First, to the mechanisms provided for packing down the individual sheaves as they accumulate in the pan, until the resistance ot the accumulating pile of sheaves against the packer mechanism serves to effect the operation of trip mechanisms which` release the pivoted inner 'frame and allow the tread members to engage the ground.

Second, to the means provided for steadying the up-ended shock and-preventing the eii'ect otl its acquired momentum from toppling over the shock as its butt end is deposited upon the ground and during the interval ot time. that the pan is passing forwardly over the top of the deposited shock.

Third, tines, which are designed to align the butts of the sheaves during the period ot accumuthis general type em-v to the arrangement of the butting.

lation, and to spread the butts laterally to 'afford an extended base for the completed shock. f f

Fourth, to the mechanism for suspending the delivery of sheaves during the dumping operation by correlated mechanisms, which are eiiiective to open the gate and allow the delivery of sheaves only during the accumulating period.

Fifth, to the means for correcting the tore and aft alignment of the sheaves with respect to the pan.

Finally, to the general construction ot' the machine as a. whole and the correlating and timing of the several mechanisms to operate in harmonious relation to one another.

Figllis la plan visavof the shocker With the Vpan in "receiving position `and Fig. 12 is a. side elevation viewed from the side adjacent the binder With the pan in receiving` position.

rlhe shocker is built Within and supported by a main frame, which comprises a pair of spaced side rails 10, 'elevated at-their forward ends 11 and connected through .the medium of corner bracket castings 12-to a cross front rail 13 which isprovided With an eye 14 .to receive the rear Aend of a diagonally disposed draft bar 15, which is connected with the draft mechanism for the hinder. "The corner bracket castings 1,2 are extended forwardly to afford socket journals 16 which receivethe upper en'dsof caster pintles 17 Whichjournal front caster wheels 18 located beneath the inner and outer front `corners of the structure. y

The frame is supported at its rear end by outer andinner ground wheels 19 aud/.20, which constitute the sources of power for the operation of the packing and eleva-ting mechanisms presently to be described. AThe side rails of the main frame :are h-eld `and braced in suital'ily spaced relation yby the provision of a rear cross frame 217 of in verted U shape, Which is connected atits center point to the rear depending leg 22 of fore and aft top frame 23, the forwardv leg 24 of which extends downwardly and Vmakes a connection with the `forward cross rail 13 of the main frame. This arrangement affords a vmain frame, Whichis open at its rear end to clear the deposited shock, and is supported centrally in such manner as to afford amp-le unobstructed Working space for the rotating movements of the-pan.

The mier panesapp ortc'ag frame.

The front bar ofthe main frame constitutes a point of pivotal attachment for an inn-er frame, comprising outer' and inner side arins25 and 26, which are integrally connected at their forward ends with a cross connectingirod 27, (see Fig. 6) which gives to the inner frame the form of a horizontally disposed U-shaped figure open at its rear end;` and the inner frame is pivoted to rock on va horizontal transverse axis, by the provision of journal plates 2S which pivotally connect the forward corners of the inner frame With the corresponding cornersvof the inainor supporting frame. The inner frame furnishes a mounting for the suspension of the open sided pan 29 which diverges from rear tofrontand is provided in its center with 'zt-longitudinally extending chan-nel or depression 30 of a size to receive and initially position the first sheaf delivered,

-' edges 'ofz the panaa'reflreinforce'd by the f pro- 'vision of side fbarsfl, which furnish the main elements of a supporting iframe or cradle 32 Which affords sufficient rigidity to the pan as a Whole.

The pan is associated with a pair of tread ii'ien'ibers' of arcuate formation, the normally lower portion 34 of each treadmember .being flattened vto clear the ground When the pan is in its normal or receiving position. The "flatt -med` portions are formed to extend in substantial parallelism with the bottom edges of the painand the treads and pan form in effect :a rigidly united structure Which .moves as a unit when the tread inembers .are brought into .ground engagement. Thepan is united tothe tread membersby the provision of rearconnecting 'bars 35 and front connecting bars 36, one of tlielat ter being shownin Fig. 3.

yThe tread members are suitably braced by radial brace members 37 suitably vdisposed to afford the necessary rigidity to permit the load in the pan tobe deposited Without unduly straining or rocking` the structure as a Whole. lThese braces :areconnected With partspresently to be described, Which in turn aregpivotally mounted With respect to .the side arms of the inner Vframe on each side, so that the pan, the treads, and all pon tions of the structure which rotate in unison With the movements of the pan will rotate about an axis having a definite bearing point yvith respect to the inner frame.

The veeleer cmd trip mechanism.

The packer and trip mechanism is located on the 'outside of the pan, and is illust 'ated in detail in Fig. 4. lit a point coincident with the axis of rotation of the pan is 'located a stub shaft 39 which is journaled through abracket bearing 40 carried by the outer rail 25 of the inner or oscillating frame The shaft at its outer endt has splined thereto a main sprocket Wheel 41 which imparts rotation to a bevel faced inner :gear 42 located between the pan andthe adjacent rail 25. A center bracket casting 43 is freely mounted upon the shaft 39 behindtlie inner bevel faced gear 42, and this casting 43 furnishes a center connection for the brace bars 37 and 38, and yfurnishes ahub 'for the outer tread member.

lThe main sprocket Wheel 41 engagesa sprocket chain 44 which is carried Yaround anvidler 45 mounted upon a swinging arm 4b pivotally supported at its upper end from a plate 47, Which is normally heldin advanced ,position by the action of a spring 48 (see Fig. rfhe plate 47 is pivotally mounted Within a recess in the bracketl bearlli) ing 40 and is provided with a stop 49 for limiting the freedom of movement between the plate 47 and the arm 46, which two elements are intended to move substantially in unison save for the slight freedomjof action indicated. The plate-47 is provided with a rearwardly extendingv finger 50 which lies immediately beneath a spring-backed detent finger 51 on atrip dog 52, which engages a notch 53 in the forward edge of a segment bar 54, which bar has a radius of curvature concentric with the axis of movement of the oscillating innerl frame; and' the bracket bearing 40 is provided with a slotted guide extension 55 which embraces the seg# ment and is designed to ride thereupon without permitting any appreciable lateral or tlistortional movement of the parts, this ar; rangement serving to steady and support the inner frame during its up and down movements, and to afford the necessary support to permit the overturning movements of thepan. The latch dog and segment may be duplicated on the opposite side of themachine and operated through themedium of companion draw rods, which connect with companion rocking fingers 57 at the opposite ends of a rock shaft 58 journalled in parallel relation to the .forward cross connection 'for the oscillating inner frame.

The center` bracket casting 43 which is mounted to rotate about the stub shaft 39 carries on the side normally to the rear a journal bracket 59 which journalsja crank shaft GO having at its normally forwardend a bevel pinion 6l which meshes with the bevel faced gear 42, and the opposite end of the shaft carries a crank 62 having pivoted thereto a link 63 which .connects with a packer crank 64 outwardly projecting from a packer rock shaft G5 jour-nailed in parallel relation to the outer edge of the pan. The packer crank, being longer than the driving crank 62, will have the rotary movements of the latter 'transformed into an oscillating movement, thereby rocking the packer shaft 65, by the employment of power derivezil from the advance of the machine. The packer shaft is providedv with a pair of tines or lingers 66 which, when the shaft is rocked, will. swing downover the open upper side thereof and press upon the sheavesdeposited therein, after the pile of sheaves has risen to a given point, and thereafter rthe oscillation of the tines willv subject the parts ,to an increase in lpressure as the pile is furtherI accumulated.

The sprocket chain 44 passes over a rear sprocket wheel 67 driven by the rear outer ground wheel, so that the chain will be con-y stantly rotated, and this rotation will continue-to oscillate the packer tines or lingers until the pile on the pan has risen to such apoint that the pressure of the tines against the accumulated pile will prevent the normal vlinger at the tail end of the trip dog, thereby releasing the dog latch and allowing the pivoted inner frame to fall until the tread members engage the ground. Thereafter the pan will rotate with the tread members and associated parts, which rotation will carry the journal bracket 59 around the axial center of the stub shaft39 at a rate uniform with the speed ofl rotation imparted to the stub shaft by the travel of the sprocket chain, so that during this period vof the operation no relative rotation will be imparted by the bevel faced gear through the engaged pinion, which holds the packer tines inl compressed relation against the upending shockuntil the same has been butted upon the ground in a vertical position. This pressure will. be maintained against the shock at apoint slightly below the head of the shock, the tines being positioned with a view of supporting the shock at this point, which allows the butts to expand during the upend ing operation. After the shock is upended, the continued advance of the machine will cause the pressure tines to travel away from the now stationary shock as the pan is swept around in its continued return movement toward its receiving position. To accommodate these movements, the gear ratio between the driving sprocket 67 and the driven sprocket 4l is commensurate with the circumferential ratio between the ground wheel 19 and the tread member 253, which insuresthe proper rotation of the intcrlocked bevel gears without the transmission of nio-- tion to the packer members during the rotan tive cycle of the pan. r v

The cov/Wesson lshock during the upending operation and support the same as the pan sweeps over the top ofthe butted shock, and with this end in view the compressor mechanism is mounted and ,actuated in such a manner as to carry its effective point of contact toward the rear as the machine advances forwardly, and to maintain this contact until the pan is well above the deposited shock, thereby counteracting any tendency for the pan to upset the shock as it begins its sweep over the top thereof. In designing this mechanism the factors involved pertain to the forward advance of the machine as a whole, to the rotative movement of the pan, and to the varying components ofl vertical and horizontal travel imparted to the compressor members by the rotationl ofthe pan on which they `are mounted. `These devices will `new be described in detail.

Figures 7 and 9 illustrate the compressor mechanism `and associated parts. The compressor arm 68 is mounted upon a compresH sorrock shaft' 69 which is=`oifset at the point TO to amplify the effect ofthe rocking movements of the shaft 69. The slraft'is journalled withina sleeve 7l and is-acted1upon by a Coilspring 72 which-'normallyhasthe eilect of swinging the offset outer en'd of the shaft with the compressor varm GS'n'iounted thereon intoupward position, so that the arm -vrill lie haelt froni=the-open mouth-of the pan insuch position as to Yail'ordnoobstruction tofthe depositing ofrthe sheaves therein.

The sleeve''l, as indicated in Fignfis provided with `a laterally extending trunn-ion 73, whichis entered througha journal 74 carried by a'braclret T''bolted orot-herwise secured to the edge of the pan, or toportions of the structure iixedly -associatedwith the pan, andthe trunnion earriesiixedly secured to its'outer end a small gear segment TNG whichl` meshes with a large lgear segment 077, the ratio -shownbeing twolto one, ,for fthe purpose of speeding' the swinging move-ment of the pressure armtoward the-back of 'the pan at thefproper point in' the tiltingE `of the The large segmentl 71`is carried by aibell crank` arm 78,'-whichispivoted vat the endof apintle 79 outstanding from the side of the pan, and the outer end of the bell Acrank farm carries a roll-er SOWhichlrides uponl afiXed cam 81 which is carried by the adjacentirail of the oscillating inner frame, Whichsarm also carries `at its end la ijrourn'al 'head "82 which receives and ljournals the outwardly proj ecting trunnion 83'v of Lay icnadletbar, which passes-under vthe pan, `said .trunni'on being alined with the stub shaftBQnon theopposite side of the pan, so that the alignment of these members fixes the axis around which the pan revolves.

vrlhe cam 81as actually constructed, is shrouded, as shown inFigrt, but in Fig-9 the parts `are indicated diagrammatically Vto better illustrate the co-operat-iverelation, and in this ligure thel'cam .is illustrated with 'the shroud removed. The rear end .of the cam is conigured to substantially :therarc of-a circle, with the trunnion 83 as -a -center, but `the forward port-ion of the cam protrudes quite;abruptly,\=sothat as the pan revolves about the trunnion kv8B as a center, the roller will initially ride freely over ldie cani without .having any relative movement imparted thereto, but, as 'th'e cycle of revolution -is continued, .the roll-er 'will encounter the fprotuberfant forward "end of the cam, thereby rocking' the 'bell crank arm 78 and causing a rotative movement vof the large segment in an inw-ard directiomwhich will impart 'a correspondingly amplified movement to the small segment, and Vthrough it tothe compressor rock shaft, which vwill be swept downwardly, as regards the base of the pan, concurrently with the forward and upwardmotion-of the rear portion of the pan as'it tilts forward in ythe operation of upending the shock. A

Prior -to `Ithe lmotions above described, :it is essential thatthe compressor 'arnr'68 be rocked' downwardly into transverse relation to the accu-undated shock 'within the pan, in `order'fto establish lan effective contact therewith priorto thebeginning of the up ending n-ioefements. To "ell'etfs't this result, the compressor rock shaft, at its point, of forward lemergence from the sleeve 71, is provided with a latch head 84 having 'anotch 85adap'ted1to -b'eL engaged by a dogSG which is pivoted fto a lug '87 depending from the sleeve 7l. The 'head S4 is provided with atail'pieee'88, and vthe 'dogis likewise provided wi'tlr a tail piece I89,*both` of whichE tail pieces are-adapted'to-ride uponand be supported by a -stop finger 90, `Whielrextends in a #substantially fore and aft direction and is carried by an =upstanding arm 91 pivotally mounted at its ylower Yend in a fittiug'QQ carried by the 'frame arm 25, a spring '193 serving lto lhold, the "darm vv91 `in retractedposition. 1lt lwill be observedthat thelatch head 84; andthe dog 86ers mounted for imovementl on separated centers, and the result ofthis arrangementis-that as the pan begins to rotate about the trunnion 83,"the` tail piece89 of the dog, being mounted upon -a lower center, ywill first be released from'fengagementbyz'the stop finger 90 and vwill fall down into positionto engagefthenotch- 85, which through fthe eontinued engagement n of the 'tai'lpiece 88 with the 'stop Y)will berotate'd u'ntila latching of the parts is effected. lThis movement of 'the parts causes a rocking of "the compressor' rock shaft and a swinging down ofi the compressor arms across the shock in the pan during the -initial increment 'of -Jthe pan, and after vthe fparts lare latched, las yabove described,'the compressor arms will be held in crosswise =relation `against `rota-tive tension-ofthe spring 72, and-thisflocked relation will continue runtil 'the cyclehas been completed, at which p'ointthe priorengagenientfof vthe dogftail'piece 89 with 'the stop finger 90 will unlatch the r`parts andallow the compressorarmsfto Aspring back vto ver tical position preparatory to the: subsequent depositing of the vsheaves yin the building up of the next su'cceedingshock.

The lefva'tor.

The-'elevator Afor liftingtheisheaves from the lbinder .deck ito '.the pointio'f :disch-arge above the pan is Well illustrated in Figs. 3

and 6. It consists ot a frame comprising side rails 94 which comprise guidetvays tor the vupward Hight ot conveyor chains 95 having -cro'ss bars 96 provided With the usual tines or fingers which project at an angle to the guideways during the upward flight and descent'in parallel relation to the chain, atter the manner usual in such constructions. The chains run over the usual sprocket Wheels, which are driven by intermeshing bevel pinions 97, Which derive power from the sprocketchain 98 driven byl the inner rear ground Wheel, but since these features are common in structures of this kind it is not deemed necessary to further describe the details. f

The elevator as a Whole is carried by brackets 99 which ext-end upwardly at an angle from the ends ot' a supporting bary 100, which ends are entered through a pair lof clips 101 adjustably mounted upon the proximate side rail 10 ot' the main `frame, which arrangement permits the elevatorto maintain a liXed tore and aft relation to the binder deck, and at the same 'time permits the shocker asa Whole to be adjusted in a fo-re and att directionin order to bring the pan into proper relation to the delivery point for the sheaves, which is desirable in order to accommodate the shocker to sheaves ot varying length and to insure the proper deposit thereof Within the pan.

The sheen" arresting and pcm locking mech- (mism.

During thedelivery of the sheaves to the pan it is necessary toprovide means for locking the pan 'against tilting or oscillation, and also to provide Jfor the recurrent opening ot the gate, which permits the down passage ol the sheaves to the pan, and these mechanisms will now be described.

The supporting bar 35, which connects the rear end ot the pan to the proximate tread member, is adapted, on its up swing, to ride over the shoulder latch 102 formed on the lower end ot the stop bar 103 Which hangs trom the rear arch 21, which latch Will spring back sutliciently to permit the bar 35 to engage the shoulder, and as the bar slips over theshoulder it will engage a stop 104, so that it will be held vfirmly locked between the shoulder and the stop during the accumulation ot the sheaves in the pan. The engagement with the shoulder is sutiiciently slight, lio-Wever, to cause the parts to clear one another when the oscillating inner trame is unlatched, the pivotalcenter of the inner frame being so arranged that the ita-lling ot the trame `and pan Will occasion a slight forward movement ot these members, so that the panxA and 'associated parts Will clear the stops Whenthe panbegins to rotate. p

The oscillating` packer shaft is provided, at its rear end, With a bent linger 105, which oscillates -up and down as the packer shaft is rocked, Which finger coacts with a centrally pivoted rocker 106 carried by the bar 235, thereby lifting the opposite end ot the rocker and causing the sameto engage 'with the inner end ot a bell crank lever 107 pivoted to the bar 103. The bell crank 107 is connected by means of a draw rod 108 with a spring 'controlled latch dog 109, the tooth 110 ot which engages With a rlatch head 111 carried by a gate shaft 112, which shaft constitutes a supportingr head for a series ot tines 113, 4which constitute a gate .tor the arresting ot the sheaves, the tines coacting With a series ot obliquely disposed slide bars 11dextending in obliquely downward relation from the top ot the elevator, so that when the gate is held in closed position, as indicated in vFig. 8, the gate tines and slide bars in unison Will provide a troughv shaped open receptacle tor the momentary arresting ofV the sheaves in their progress to the pan. This arrangement also insures a correct fore and-aft position ot the sheaves at this point, so that they Will descend'to the pan vin certain and orderly progression.

So long as the pan remains in locked horizontal relation, the finger 105, at the tail end ofthe packer shaft, Will With each return movement effect an unlatching ot the gate controlling mechanism, so that the re lease and falling of the she-aves Will occur in alternate timed relation to the active movement-s ot'the packer, so long as the bundles are accumulating in the pan. This insures against interference otthe sheaves with the packer mechanismen its ret-urn movements, and at the same time provides automatic mechanism for suspending the delivery' ol' the sheaves during the period ot rotation ot' the pan in upending the accumulated shock, since the latch releasing mechanism is operated only during the time the pan occupies its normal or horizontal position, the gate relmzining locked during the delivery ot the s oc r.

In order to insure a correct positioning ot the sheaves during the accumulating period, and to provide tor a spreading ot the base ot the shock during the upending thereof, a plurality of butting tines 115 are provided, the upper ends ot Which are secured to a cross header bar 116 which is supported upon the front leg 24 ot the top arch, and the abutting tines are arranged in downwardly diverging relation tov one another, the lower ends 117 being given a zigzag or sinuous. configuration crossWise ot the pan, which zigzag arrangement increases the eftective lateral dimension ot each tine at its liti) lower-end, and y'facilitates the separation and spreading of the grainstalks, so that as the pan is upended'the grain stalks composing the butt end ofthe shock will be laterally separated and the butt end distended to afford an enlarged basefor the shock.

Adjustable tread shoes.

Each of the tread members is provided on its periphery with an adjustable tread shoe 118, which is pivoted at its forward end 119, and-secured at its rear end by an adjustable clip 120, so that the radius of action of` the arcuate tread members can be increased or diminished 'within given limits, the tready shoes being located in proper position to occasion an augmented lifting effect atthe time the pan is clearing the deposited; shock, andthe shoe members are made adjustable in order to accommodate the mechanism to shocks ofvarying height.

The axis of the pan is located at a point below the center of each tread member, and forwardly thereof, so that the liftingy effect of the tread members, irrespective of the shoe attachments, will be at a maximum during the time the; pan is clearing the deposited shock, and during the cycle of operations the oscillating inner frame and pan will, ofcourse, move up and down in conformity with the movements occasioned by theriding of the tread members over the groundl surface;-

T/re. operation.

In operation, with the pan in horizontal or receiving position, the sheaves will be carried by the elevator and discharged onto the sloping guide bars 114 in horizontal relation with their butt ends forward. Each sheaf will be momentarily arrested bythe gate as the packer tines are swung down over the open sidey of the pan. As the tines return to upright position, the gate will open andthe sheaf` will be dropped into the pan. The rst sheaf will assume a position within the depressed centerportion of the pan and constitute a base or foundation around and above which the remaining sheaves will be accumulated in symmetrical arrangement. Ata given point in the accumulating of the shea-ves'the packing tines will begin to exert pressure against the sheaves, tending to. force them down into a compact mass, and after the-sheaves have accunmlated to. a. predetermined amount the pressure of the packing lines will increascsto a degree sufficient to overcome the tension of the spring,` which normally tends to retract the idler over which the packer drive chain passes. This will' arrest the free travel of the chain, and the pullthereofagainst trie idler will effect an unlatching of the-oscillating inner frame witlrithe pan and tread members rigidly associated therewith. The tread members will thus be dropped to position toengage-the ground andthe revolution of thepan will begin.

As the pan'begins to revolve, the compressor members on fthe opposite side of the panwill begin to act. Thefirst operation of the compressor shaft-will be a partial rotation thereof in such direction as to throw down-the compressor arms to embrace the shock at a point somewhat tofthe rear of the center, andthe-shock will thus be held rmly within the pan by the conjointact'ion of the packer and ycompressor members. As the pan is upended, the travel of the roller 80 along the cam 81 will effect apartial `rotation of the intermeshing gear` segments, which will occasion a back sweepv of the compressor shaft toward the base of the pan concurrently with the turning movement ofthe pan in a forward direction., By the time thel pane has assumed a substantially vertical position, the shock will be butted uponthe grounch but the arcuate sweep of the-rear-l end of the compressor shaft will continue, in a downward andrearward direction, thereby firmly supportingand forcing down the shockl against the ground as the machine advances to clear the shock. The compressive movement of the shaft is speeded or amplified by the adoption of a multipli-ying gear ratio, which ratio is chosen withfdue regard to the length olf/the compressor shaft and the rotative movement of the pan, with the result that the active end of the compressor shaft will move rearwardly as the machine advances and maintain contact with the shock for a sufficient length of time to insure against a'toppling over of the shock as the pan sweeps over thetop of the shock .on its return movement.

The, arrangement of the butting tines is such that as the shock is being upended the butt ends of the grain .stalks composing the sheaves will be laterally, separated and the base. of the shock distended, the zigzagv rangement of the individual tines and their divergence from. the vertical center line serving to afford sufficient resistance to1 thev movement of the butt ends to yeffect a substantial spreading ofthe base of the. shock.l

After the shocklias been delivered, the continued ground Contact of the tread members will carrythe pan around to its origina-l position, the acquired momentum serving to swing up the pan toY latching-posit-ion. so that the subsequent oscillation of the pan will be prevented and the pan positively maintained in horizontal position during the a eci i mulating period.

The arcuate guideIbai-s 11 in; engagement with' the opposite rails ofthe oscillating inner fraaiev servesto insure adequateuguiding and support forthe free ends of vthe-oscillating Vframe and to guard the.k sam-e against torsional strains and to insure a: positive llO positioning of the operating parts at all times.

Although the combined packer and trip mechanism above described is primarily designed for usein connection with a grain shocker, it is evident that it'might be effectively employed in connection with other classes of mechanism in Which it is desired to automatically effect a tripping of the parts by an increase in the pressure, due to an accumulation of' material in contact With the packer mechanism, and it is not the intention, unless otherwise indicated in the claims, to confine the use of the combined packer and trip mechanismt'o grain shockers. The implement as a Whole is so designed as to be entirely automatic in its operation, the various mechanismsbeing rsotimed and harmonized in action as to perform the cycle of operations necessary in the accumulation and deposit of shocks of grain Without any. attention on the part of the driver of the harvesting machine; and at the same time the various mechanisms are adjustable to meet the requirements of grain sheaves of varying Vheight and to insure a proper accumulation of the same.
