BERRY SHOCKER INCORPORATED, 0F OF DELAWARE.

WILMINGTON, DELAVJARE, A CORPORATION GRAIN SHOCKER.

Application filed July 10,

The shocker of the present invention is of the general type shown and described in the Bert C. Berry applications, Serial No. 318,738, filed August 30, 1919. and Serial No. 446,843. filed January 8, 1921, and in my own application, Serial No. 544,514, filed March 17, 1922; and the present invention is directed primarily to certain improvements in the means provided for delivering the grain sheaves from the deck of a self-bind ing harvester to the sheaf receiver or pan in such a manner as to maintain practically a continuous mechanical control of the sheaves during the time of such delivery. In certain prior constructions it has been customary to allow the sheaves to drop by gravity from an elevated point above the pan, but this method of delivery is sometimes defective, in that it allows more or less disarrangement of the sheaves within the pan and at the same time requires a heavy and cumbersome superstructure for the purpose of elevating the sheaves to the desired point, and is wasteful of power and otherwise objectionable.

The grain shocker of the type to which this invention pertains employs an opensided pan or sheaf receiver into which the sheaves are projected by the delivery mechanism of the present invention. The sheaves fall into the pan with their butt ends 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 which 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 of the shock in its return to normal or receiving position.

The shocker of the present invention embodies the following instrumentalities:

First.-Ihe delivery mechanism for positively engaging the sheaves received from the deck of the binder and for carrying the same toward the pan with their butt ends projecting forwardly. This delivery mechanism retains possession of the sheaves until they are well advanced toward the center of the pan, and imparts to each sheaf a final 1922. Serial No. 574,022.

thrust toward the bottom center of the pan. which tends to regulate the accumulation of the sheaves in an even and orderly manner.

Second-The mechanisms provided for packing down the individual sheaves as they accumulate in the pan. until the resistance of 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.

Third-The means provided for steadying the upended shock and preventing the effect of its acquired momentum from toppling over the shock as its butt end is deposited upon the ground and during the interval. of time that the pan is passing forwardly over the top of the deposited shock.

Fourth.The arrangement of the butting tines, which are designed to align the butts of the sheaves during the period of accumulation, and to spread the butts laterally to afford an extendedbase for the completed shock.

Finally-The general construction of the machine as a whole and the means for correlating and timing of the several mechanisms to operate in harmonious relation to one another.

The 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 is provided with an eye of the packer forward inner -14 to receive the rear end of a diagonally disposed draft bar 15, which is connected with the draft mechanism of the binder. The corner bracket castings 12 are extended forwardly to afford socket journals 16 which receive the upper ends of caster pintles 1'? which journal front caster wheels 18 located beneath the inner and outer front corners of the structure.

The frame is supported at its rear end outer and inner ground wheels 19 and 20, which constitute the sources of power for the operation of the packing and delivery mechanisms presently to be described. The side rails of the main frame are held and braced in suitably spaced relation by the provision of a rear cross frame 21, of inverted U-shape, comprising outer and inner vertical legs 22 and 23, which are connected to the side rails near the rear wheels, thereby affording a substantial main frame, which is open at its rear end to clear the deposited shock, and to afford an unobstructed working space for the rotating movements of the pan.

Cit

The inner pan-supporting frame.

The front bar of the main frame constitutes a point of pivotal attachment for an inner frame, comprising outer and inner side arms 25 and 26 which are integrally connected at their forward ends with a cross connecting rod 27 (see Fig. 1), 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 a horizontal transverse axis, by the provision of journal plates 28 which pivotally connect the forward corners of the inner frame with the corresponding corners of the main or supporting frame. The inner frame furnishes a mounting for the suppension of the open-sided pan 29, which diverges from rear to front and is provided in its center with a longitudinally extending channel or depression 30 of a size to receive and initially position the first sheaf delivered, which thus constitutes a foundation upon which the remaining sheaves are built up in symmetrical relation. The body of the pan is formed of sheet metal, and the upper edges of the pan are reinforced by the provision of side bars 31, which furnish the main elements of a supporting frame or cradle which affords sufficient rigidity to the pan as a whole. 7

The pan is associated with a pair of tread members 33 of arcuate formation, the nor maily lower portion 3a of each tread member be hittened to clear the ground when the in its or receiving position. .i .c i tened portions are formed to extend in substantial parallelism with the bottom edges of the an, and the treads and pan n in effect a rigidly united struc ure -cl1 moves as a unit when the tread members are brought into ground engagement. The pan is united to the tread members by t e provision of rear connecting bars 35 and n; connecting bars 36, one of the latter shown in Fig. l.

In order to facilitate the delivery of the sheaves in a manner to be presently described, the inner tread member is cut away at a point adjacent to the upper inner mars of the pan, that the final return move- 5 of the empty pan, after delivery of sheaf, is effected solely by the outer ad member, although both inner and outer tread members cooperate while the pan is subjected to the weight of the shock being upended.

The tread members ar suitably braced by upper and lower radial brace members and 38 suitaoly disposed to afford the necessary rigidity to permit the load 1 in the pan to be deposited without unduly strainii rocking the structure as a whole. 'cse braces are connected with parts presy to be described, which in turn are pivly mounted with respect to the side arms f the inner frame on each side, so that the an, the treads, and all portions of the strucwhia-h rotate in unison with the moveof the pan will rotate about an axis definite bearing point with respect 2' he packer and trip mechanism.

The iacker and trip mechanism is located or the inner side of the pan, and is illusframe. The shaft at its outer end has splined thereto a main sprocket wheel 41 which imparts rotation to a bevel faced inner gear located bet-ween the pan and the adjacent rail 25. A center bracket casting 43 is freely mounted upon the shaft 39 behind the inner bevel faced gear 42, and this *asting 43 furnishes a center connection for the brace bars 37 and 38, and furnishes a hub for the outer tread member.

The main sprocket wheel 41 engages a sprocket chain 44, which is carried around an idle-r 45 mounted upon a swinging arm 46 pivotally supported at its upper end from a plate 47 which is normally held in advanced position by the action of a spring 48 (see Fig. 6). The plate 47 is pivotally mounted within a recess in the bracket bearing 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 freedom of action indicated. The plate 47 is provided with a rearwardly extending finger 50 which lies immediately beneath a spring-backed detent linger 51 on a trip dog 5:2, 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 inner frame; and the bracket bearing 40 is provided with a slotted guide extension 55, which embraces the segment and is designed to ride thereupon without permitting any appreciable lateral or distortional movement of the parts, this arrangement 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 the pan. The latch dog and segment are duplicated on the opposite side of the machine and are operated through the medium of companion draw rods 56, which connect with companion rocking fingers 57 at the opposite ends of arock shaft 58 journaled 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 journals a crank shaft 60 having at its normally forward end a bevel pinion 61 which meshes with the bevel faced gear 42, and the opposite end of the shaft carries a crank 62, having pivoted thereto alink 63 which connects with a packer crank 64. outwardly project ing from a packer rock shaft 65 journaled 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 derived from the advance of the machine. The packer shaft is provided with a. pair of tines or lingers 66 which, when the shaft is rocked, will swing down over the open upper side thereof and press upon the sheaves deposited therein, after the pile of sheaves has risen to a given point, and thereafter the oscillation of the tines will subject the parts to an increase in pressure as the pile is further accumulated.

The sprocket chain 44 passes over a rear sprocket wheel 67 driven by the rear inner ground wheel, so that the chain Will be constantly rotated, and this rotation will continue to oscillate the packer tines or fingers until the pile on the pan has risen to such a point that the pressure of the tines againstthe accumulated pile will prevent the normal reciprocation of the parts, thereby in effect locking the sprocket wheel and gear train against the transmission of power, and in thee circumstances the continued pull along the lower course of the chain 44 will have the effect of drawing back the idler arm 46 against the tension of the spring 48, which will result in a kicking upo" the detent finger 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 assocla-ted parts, which rotation will carry the journal bracket 59 around the axial center of the stub shaft 39 at a rate uniform with the speed of rotation imparted to the stub shaft by the travel of the sprocket chain, so that during this period of the operation no relative rotation will be imparted by the bevel faced gear through the engaged pinion, which holds the packer tines in compressed relation against: the upending shock until the same has been but-ted upon the ground in a vertical position. This pressure will be maintained against the shock at a point 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 extend during the upending operation. After the shock is upended,

the machine will the continued advance of cau e the pressure tines to travel away from the now s suionarv shock as the pan is swept arounc in its continued return movement toward its receiving position. To accommooate these movements. the gear ratio between the driving sprocket 67 and the driven sprocket 41 is commensurate with the circunn' erential ratio between the ground wheel 19 and the tread member 33. which in ure the proper rotation of the interlocked bevel gears without the transmission mechanism whose purpose is mounted and actuated to amplify the el thereon into upward ,provided with a laterally of. motion to the packer members during the rotative cycle ot the pan.

The compressor.

pan is located to steady the operation and -On the opposite side of the shock during theupending support the same as the pan sweeps over the top of the hutted shock, and with this end in view the coin n'essor mechanism is in such a manner as to carry its effective point of contact toward the rearas the n uichine advances forwardly, and to maintain this contact until the pan is'well above the deposited shock, thereby counteracting anytendency t'orthe pan to upsetthe shock as'it begins itssweep over the-topthereot. in designing thismechanism, the factors involved pertain to the forwardadvance oi the machine as a whole,

to the r-otative movement of the pan, and to the varying components of vertical and hor- 'lZOfitdl travel imparted to the compressor members by the rotation of the panon which theyare mounted. lhese devices will now 'be described in detail.

Figures 1 and 8 illustrate the compressor mechanism and associated parts. The com- 68 ismounted upon a compressor roclr shaft 69, which is offset at the point feet of the rocking movements ot'the shaft 69. Pneshat't is journaled within a-sleeve 71, and is acted upon b a coil s rin -72 which normally has the y P o effect otswinging the oiisct outer end of the shaft with the compressor arm (38 mounted position, so that the arm will lie back from the open mouth of the pan insuch position as to a'ti'ord no obstruction to the deposition or the sheaves therein.

The sleeve '71, as indicated in Fig. 8, is

extending trunnion 73, which is entered through a journal Te carried by a bracket 7 5, bolted or otherwise secured to the edge of the pan or to portions of the structure fixedly associated with the pan, and the trunnion carries fixedly secured to its outer end a small gear segment '7 6 which meshes with a large gear segmentTT, the ratio shown being two to one, for the purpose of speeding the swinging movement of the pressure arm toward the. back ot the pan at the proper point in the tilting of the pan.

The large segment 7'? is carried by a bell crank arm '7 8 which is pivoted at'the end 01 a pintle 79 outstanding-from the side of the pan, and the outer end of the bell crank arm carries a roller 80 which rides upon a fined cam 81 carried by the adjacent rail ot the oscillating inner frame, which rail also carries at its end a journal head SZ'w'hich receives and journals the outwardly projectmovements. )IGSSOI rock shatt at its oint 0t torward on separated centers, and

passes underthe pan, said trunnion being alined with the stub shaft 39 on the opposite side of the pan, so that the alinement of these members fixes the axis around which the pan revolves.

The cam 81, as actually constructed, is of openworlrformation, as shown in Fig. 1, but in Fig. 8 the parts are indicated diagrammatically to better illustrate the co-operative relation, and in this figure the. cam is illustrated with the shroud removed. The rear end or the axis of the cam is configured to substantially the are of a circle, with the trunnion 83 as a center, but the forward portion of the cam protrudes quite abruptly, so that as the pan revolves about the trunnion 83 as a center the roller 80 will initially ride freely over the cam without having any relative mov ment imparted thereto, but, as the cycle of revolution is continued, the rollor will encounter the protuberant forward end of the cam, thereby roclring the bell crank arm 78 and causing a rotative movement of the large segment in an inward direction, which will impart a correspondingly amplified movement to the small segment, and through it to the compressor rocli shaft, which will be swept downwardly, asregards the base otthe pan, concurr ntly with the torward and upward motion or the rear portion of the pan as it tilts forward in the operation ot-upending the shock.

Prior to the motions above described, it is essential that the compressor arm 68 be rocked downwardly into transverse relation to the accumulated shock within the pan, in order to establish an eliective contact therewith prior to the beginning of the upending To effect this result, the comei'nergence from the sleeve 71, is provided with a latch head 8st having a. notch 85 adapted to be engaged by a dog 86 which is pivoted to a lug 87 depending from the sleeve 71. The head 8ais provided with a tail piece 88, and the dog is likewise provided with a tail piece 89, both of which tail pieces are adapted to ride upon and be supported by a stop finger 90,-which eX- tends in a substantially fore and aft direction and is carried by an upstanding arm 91 pivotally mounted at its lower end in a fitting 92 carried by the frame arm 25, a spring 93 serving to hold the arm 91 in retracted position. It will be observed that the latch head 84: andthe dog 87' are mounted tor movement the result of this arrangement is that, as the pan begins to rotate about the trunnion 83, the tail piece 89 ct tl e dog, being mounted upon a lower center, will first'be released from engagement by the'stop finger 90, and will fall down into position to engage the notch 85, which, through the continued engagement of the tail piece 88 with the stop, will be rotated until a latching of the parts is eflected. This movement of the parts causes a rocking of the compressor rock shaft and a swinging down of the compressor arms across the shock in the pan during the initial movement of the pan, and after the parts are latched, as above described, the compressor arms will be held in crosswise relation against rotative tension of the spring 72, and this locked relation will continue until the cycle has been completed, at which point the prior engagement of the dog tail piece 89 with the stop finger 90 will unlatch the parts and allow the compressor arms to spring back to vertical position preparatory to the subsequent depositing of the sheaves in the building up of the next succeeding shock.

Y 716 sheaf delivery mechanism.

The mechanism for successively receiving the sheaves from the binder deck and carrying them over and thrusting them toward the bottom center of the pan will next be described: This mechanism comprises a set of arms 91, three being shown in the present embodiment, which arms merge into a supporting head 95 journalled on a rocking crank 96, the ends of which are carried by forward and rear journals 97 and 98 mounted upon and carried by the inner rail 10 of the main frame. The rear end of the rocking crank, beyond its point'of emergence from the journal 98, is bent to aflorda crank arm 99, which has pivoted thereto a link 100, the upper end of which is journalled on a relatively in Fig. 3. This arm 101 is mounted at the rear end of a short stub shaft 102 carried by a journal bracket 103, which constitutes a portion of a housing 104 rigidly secured to the inner leg of the rear cross frame 21 at a point slightly below the level of the upper margin of the pan when in normal or re ceiving position. The stub shaft 102 carries at its forward end a bevel pinion 104 which meshes with a bevel pinion 105 fixedly mounted upon a shaft 106, upon which is freely mounted a sprocket 107 driven by a chain 108 meshing with a driving sprocket wheel 109 on the axle of the rear inner ground wheel 20, the arrangement being such as to impart rotation through the bevel pinions, when the shaft 106 is in clutched relation to the sprocket wheel 107, through clutching elements presently to be described.

The shaft 106 has slidably splined thereto a clutch collar 108 which is grooved in the usual manner to receive an operating pin 109 carried by a swinging arm 110 pivoted at its rear end to the wall of the housing 104. The sliding clutch companion clutch element 111 which is rigid with the freely mounted sprocket wheel 107, so that when the clutch elements are enshort crank arm 101, best shown element coacts with a gaged, rotation will be imparted to the shaft 106, and through the shaft to the internieshing bevel pinions which impart rota.- tion to the stub shaft 102 and to the crank 50?, which rotating movement is transformed into an oscillating movement of the crank 96 which actuates the delivery arms.

In order to throw the clutch out of mesh and stop the delivery of sheaves during the dumping operation of the pan, the following mechanism is provided: The trip dog 52, above the point of connection with the rod 56, is provided with an upwardly extending arm 112 which connects with a rearwardly extending push rod 113 carrying a pin 114, nd the end of the arm is freely entered through a perforation 115 in a lever arm 116 carried on the end of a short rock shaft 117, which is rearwardly bent at its end 118 and beveled or mounted at its end 119, so that as the rock shaft 117 is rotated the beveled end of they arm will engage the clutch operating lever 110 and retract the slidable clutch c01- lar, thereby breaking the clutch during the shock dumping operation. The parts will be held out of clutch against the tension of a coil spring 120 on the shaft 106during the dumping operation, but the movable clutch element will be released and thrown into clutching engagement after the dumping operation and while the pan is being restored to normal position by the action of a trip linger 121 carried by the proximate in: ner tread member 33, which on its return m-zwement strikes against a trip arm 122 constituting an extension of the lever 116, serving to throw back the lever to normal position, thereby lifting the arm 118 out of engagement with the clutch lever. The relation of the trip finger 121 and the trip arm 122 is such that when the inner frame which carries the pan is tripped and swings downwardly to bring the tread members into ground engagement it will be thrown forward sufliciently to permit the trip finger and arm to clear one another as the rotation of the pan begins,- but as the parts are bein restored to normal position the finger wifi encounter the arm and trip the clutch in-the manner indicated.

In order to permit the sheaves to be de livered into the pan when in receiving position, without interference from the inner read member, the latter is cut away at a point adjacent to the normally upper side of the pan, as indicated in Fig. 5, but in order to increase the ground engagement of the inner tread member, the latter is provided, a point adjacent to its normally forward upper terminal, with a tread extension 123, which is pivoted at its rear end to a bracket plate 124: and held in elevated relation by the action of a flat spring 105 which will yield under pressure and allow the tread extension to swing inwardly and thereby constitute an .796. This arrangement impar efiective extension of the tread surface while t e pan is being overturned.

Each delivery armtd is provided at its upper end with a head piece 125, which carries a pair of distended fingers 126 which engage. thesheaves, and these lingers operate intermediate a set of arcuate guide bars 127 which in unison constitute acurved delivery deck for directing the sheaves upwardly and outwardly to a point above the inner edge of the pan. l'n order to steady the sheaves in their, upward and outwardtravel, a set of tines 128is provided, which tines overlie the guide bars 12? and are carried by a frame 129 secured at its rear end to the inner leg of theframe 23 and at its forward end to a front upper crossframe 130.

Each arm 94: is also provided with an intermediate linger 130 consisting of a forward section 130" normally disposed at substantially right angles to the arm 9% and an obliquely disposed rear section 130 which terminates in an inwardly extending journal sectionlBO which .is connected through the arm 9 1 and through a spaced clip 130 to afford an extended hearing. A coil spring 130 surrounding the journal section normally holds the rear linger in its extended position, the spring action being limited by an inturned'stop 130 on the end of the section 130", as indicated in Figs. 9 and 10.

V7 The head 95 which supports the delivery arms is provided with a tail extension 131 which is pivoted to a crank arm 132, the forward'end of which is journaled in a journal bracket 133 integrally formed with the j ournal bracket 9? which carries the main crank L5 to the acting outer ends of the delivery arms an arcuate movement such that, when in their lowenmost orreceiving position, the diverging fingers" 126 will lie practically below or within the plane ofthe guide bars 127, and such that, asthe arms at are lifted, the fingers will sweep up and through the spaces subtended between the guide bars, carrying the engaged sheaf upwardly and outwardly and imparting to the latter a final downward thrust toward the base of the pan as the sheaf is delivered.

In order to spread the butt of the shock as the same is being upended, a set of spreader tines 134: are provided which are supported at, their upper ends from the upper front cr'ossframe 130, the lower ends of the tines being given a sinuous or formation to adord a more effective engagement with the butt ends of the stalks constituting the shock.

lnorder to positively hold the pan in elevated position during its receiving operation, a} spring. latch 136 is provided which is carried by a depending bar 13? secured to the rear frame 21, .vhich spring latch co-acts with a stop 138, the relation being such that as the bar 35 which supports of the pan is swung upward movement it will be enga tween the spring latch am cated in Fig. 3.

In order to regulate or ttCljl action of the tread members, tread member 33 is provided'with a which overlies the outer surf member and is pivoted ward end to a clip 1 10 carried provided its rear end with member, and is the rear end on the return l latched bestop, as indishoe 139 cc of the tread at its normally forby the tread a ll shaped stirrup 1&1 which straddles the tread member and is adapted to hold the shoe at varying distances from the tread member through the action of a cross pin or bolt l i-2, adapted to be entered through a selected. pair of holes 1&3. Lie location of this shoe is such that it serves to vation of the pan overturned position late the elethe time it is in and soniersaulting over the too of the deuosited suocl: and the inward movement of the shoe is limited by a set screw 14-1, (see Fig. 1.)

T he operation.

In operation, with the pan in horizontal or position, the sheaves will be thrust time by the swing of the dereceiving forward one at a livery arms,

pan,

which deposit shea iving to each a final thrust or impetus ves in the in a downwarddirection toward the center of the pan.

The first s if delivered will fall into the center depre o i in the pan and constitute a base above; which the remaining sheaves will be accumulated in orderly manner.

The ntermediate ranged as to yield a regular and fin ers 130 are so ar- 2: 1 p when the shear is encountered on the return movement of the arms 9% and-thereafter spring up in place behind the sheaf preparatory to an upward livery.

At a given point in the accumulating of the sheaves, the packing tines will begin to exert pressure against the sheaves, tending to force them down into a compact mass, and

determined amount the pre mg t1nes will increase to a deg" to overcome the tension of th normally tends to which the packer drive chain passes;

thus be dropped to position to engage the ground, and the revolution of the pan will be in.

is the pan begins to revolve, the compressor members on the opposite side of the pan will begin to act. The first 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 to the rear of the center, and the shock will thus be held firmly within the pan by the conjoint action of the packer and compressor arms, As the pan is upended, the travel of the roller 80 along the cam 81 will effect a partial rotation of the intermeshing gear segments, which will occasion a back sweep of the compressor shaft toward the base of the pan concurrently with the turning movement of the pan in a forward direction. By the time the pan has assumed a substantially vertical direction, the shock will be butted upon the ground, but the arcuate sweep of the rear end of the compressor shaft will continue, in a downward and rearward direction, thereby firmly supporting and forcing down the shock against the ground as the machine advances to clear The compressive movement of the shaft is speeded or amplified by the adoption of a multiplying gear ratio, and with due regard to the correlation between the length of the compressor shaft and the axis of 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 suflicient length of time to insure against a toppling over of the shock as the pan sweeps over the top 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 zigzag arrangement of the individual tines and their divergence from the vertical center line serving to afford suflicient resistance to the movement of the butt ends to effect a substantial spreading of the base of the shock. a

After the shock has been delivered, the continued ground contact of the tread members will carry the pan around to its original position, the acquired momentum serving to swing up the pan to latching position,

so that the subsequent oscillation of the pan will be prevented and the pan positively maintained in horizontal position during the accumulating period.

The arcuate guide segment bars 54 in engagement with the opposite rails of the oscillating inner frame serve to insure adequate guiding and support for the free ends of the oscillating frame and to guard the cycle of operations same against torsional strains and to insure a positive positioning of the operating parts at all times.

Simultaneously With the tripping of the inner frame Which supports the pan, the clutch which controls the application of power to the arms will be disengaged, thereby suspending the delivery of sheaves until the dumping operation has been completed and the pan again restored to receiving position.

It will be noted that the packer arms are held in their projected position, in contact with the shock during the butting operation, and the relation of the parts is such that the packing fingers and the delivery arms act in alternation to one another; that is to say, as the packer arms are swung inwardly toward the base of the pan the delivery arms are being retracted, and vice versa, so that the packer arms will stand out of the way during the delivery of each sheaf into the pan, and likewise the delivery arms will stand back out of the way while the pan is being overturned, the driving connections being properly timed and harmonized to insure this result.

The implement as a whole is so designed as to be entirely automatic in its operation, the various mechanisms being so timed and harmonized in action as to perform the necessary in the accumulation and deposit of shacks 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 height and to insure a proper accumulation of the same.
