Application filed September 20, 1926. Serial No. 136,703.

This invention relates to improvements in stookmg machines, Wltll'tllfi princlpal ObjQCt of providing a mechanical device which may i be secured in a suitable manner to a binder for the stocking of grain;

A-further object is to provide a stooking device of this character which may be at tached to binders already in existence with-, out incurring a great deal of expense.

A still further object is to provide an improved dev'ce of this character which operates automatically when a predetermined number of sheaves have been delivered thereto. A yet further object is to provide a machine of this character which may be used effectively on either a right or left hand out binder.

VVith the foregoing and other objects in view, the invention consists essentially of a frame attached to the binder upon which is mounted a conveyor, a hopper and a grain stooking basket whereby the grain as received from the binder is carried to the hop per and, when a predetermined number of sheaves have been received in the hopper, they are automatically released and discharged into the stooking basket which, through automatic mechanical means causes the grain to be placed on the ground in stook formation.

Referring now to'the drawings which disclose a preferre'd'embodiment of my invention, A represents the shocker as a whole comprising 1n the ma n the elevator, the'hopper and the sheaf-carrying basket indicated by the letters A, B, and C respectively.

As particularly illustratedin Figure 1, the

improved device is carried by the frame 10 which is secured in any well. known manner to the frame of the binder D. III-the ordinary operation of the binder the grain is cut and conveyed to the binder deck E where it is tied in sheaves or bundles and discharged therefrom by mechanism well known in the art. The sheaf,on being discharged from' the binder deck, is'received by the conveyor A when it is carried upwardly'and discharged into thehopper B. The elevator construe-'- tion shown here comprises the sprockets 12 and 13 mounted on the shafts *land 15 "which are supported by the frame 16 and connected by the chains 17 and 18,tlie conveyofmm ber 11 being secured to the linkmembers of thechains. feature of the elevator is the fact that it is designed to operate in a reciprocatory movement; For this purpose the gears 12 are loosely mounted on the shaft 14 (see Figure 10) While the sliding clutch member 19 is keyed thereto. Thelink 20is connected to the bell-crank lever 21 which is in turn connected to the clutch member 19 and. to the lever 22 which is pivotally mountedin" the bracket 23; Theupper extremity of the and, through. automatically timed 'm'echa nism, discharge the sheaves into the basket C.

opening of the hopper and directly therebelow is the sheaf-carrying basket C. This basket is designed to receive the sheaves discharged from the hopper B, after which they I tien and prior to forming a stock, is designed to travel rearwardly and forwardly through the operation of suitable mechanism. For this purpose the basket is mounted on a carriagegprovided with wheels 36 which are designed to travel on'the tracks or guideways 37 and 38. The wheels 39 mounted in a horizontal plane adjacent the wheels 7 36 are adapted to act as anti-friction rollers and eflfect a smoothworking action when the carriage is, in operation. Secured to the basket member substantially midway thereof is a secondary supporting arm 40 upon the free end of which is rotatably mounted the grooved rollers 41. These rollers are adapted totravel on the curved and inclined track or guide rail 42 which is supported by the frame with suitable. brace members. Releasably mounted adjacent the base of the basket and designed to fit into. the scmiti cum-1y illustrated circular slot 43 is the plate 44 forming the base or bottom of the basket, While. substania y midw y 9 the ba ket are pe i connected the. sheaf-retaining fingers 45 and 46 Figure 5). As will be hereinafter more fully referred to, the fingers 44, as pari F re, are- Ina], open osition. As the basket travels up the curve inclined; track 42 the latch memhers 47 and 48 are engaged and tripped by the projectingarm-49 mounted on the track (see Figure 1).. This action causes the springs 56 to pull the fingers 45 and 46, (see igures 5 and 6.) a manner so as to nearly span the open side of the basket 29, In this way the'sheavcs are held in stock formation while the basket is in a vertical position.

The fingers 45"and 46 are designed to oper ate in a lateral direction, and for this purpose are mounted in housings 51 secured to the'basket. The pulleys '52connected to the fingers 45 and 46 are. designed to be engaged a chain'or cable 53 travelling over the pulleys 54, 55 and 56on the basket, one end of the chain being secured to the member 44 asat 57 while the other end is secured to the coil spring 58 enclosed in the housing 59 which is also secured to the basket.

The operation of the basket is designed to automatic, and the mechanism for this purpose comprises, the shaft 60 connected by the chain 61 to the sprocket 62 which is mounted on the shaft 14. It might be well to state here that the shaft 14 rotates continuously, while the binder is in motion, and the several mechanisms which'will be further described are adapted to automatically en gage and disengage and thereby effect the operation of the various elements.

The lever member 63 (see Figures 1 and 4) is pivotally mounted at 64 and connected by the link member '65 to the substantially L-shaped lever 66 which in operation causes the sliding gear 67 to engage the mutilated gear 68 mounted on the shaft 69. The sprocket 70 also mounted on this shaft is connected by the chain 71 to the sprocket wheel 7 2 in turn mounted on the shaft 7 3'. The bevelled gear 74 is keyed to this shaft, and it is through this gear, which meshes with the bevelled gear 34, that power is delivered to carry the basket from a horizontal to a vertical position. The means for restoring the basket from the vertical to the horizontal comprises the mutilated gear 7 5 and the full gear 76, the latter of which is mounted on the shaft 69, the gear 7 5 referred to effecting the reversal of rotation of the shaft 69 and consequently that of the shaft 7 3, the lever 77, through automatic meanslater re ferred to, effecting the necessary reversal.

During the stooking operation, the carriage 35 will move rearwardly and at a predetermined point discharge the sheaves in stook formation. The means for effecting this operation include the sprocket 7 S mounted on the shaft 14 and connected by the chain 79 to the sprocket 8,0 which is keyed to the shaft 81. The sliding clutch member 82 is designed to' engage and disengage the loosely mounted sprocket 83 which is connected by the chain 84 to the sprocket85 mounted on the shaft 86-whiach is in the form of a reversing spiral. The carriage 35, through the arms 87 and bearing 88, is connected to this shaft 86 and it is through the operation of this sh aft that the carriage is moved in a rearward and forward direction. The means effecting the engagement of the member 82 comprise the lever 89 pivotally mounted at 90 and connected by the link 91 to the bell-.crankQQ which is pivotally mounted on the member 82, while the disengaging means comprise the lever member 98 pivotally mounted at 94 and also pivotally connected to the member 82.

In operation, and after the sheaves have been discharged from the binder deck E, as previously described, they are deposited on the conveyor 11. At this point, the rotation of the gear 25 operating the discharge arm will cause the pin 24 to engage the upper eX- tremity of the lever 22, tripping the same and causing the clutch member 19, through the link 20 and lever 21, to mesh with the gear 12 causing the member 11 to move upwardly until, as indicated in dotted lines, the member reaches a substantially vertical position at the top of the sprocket 18. Mounted on .the completion of the upward movement of the member 11, the member will engage the member 96 and automatically cause the clutch 19 to disengage. During the upward movement of the member 11 the spring 97 will have.

been tensioned and upon the disengagement of the clutch 19 the spring 97 will act to restore themember 11 to normal position, as illustrated in Figure 1. The reciprocative movement just described will, through the sprocket 98 and chain 99, cause the sprocket to make a partial revolution. This sprocket, mounted on the shaft- 101, is connected by the chain 102 to the sprocket 108. Mounted on this chain is alever engaging dog or projection 104 which will, after a series of operations of the member 11, make a complete revolution. Therefore, when a predetermined number of sheaves have been delivered to the hopper B, the member 104 will engage and trip the curved portion of the latch 28, thereby releasing the door 26 and permitting the sheaves by their own weight to slide into thebasket C, after which the action of the spring 106 will cause the door 26 to close. The forward movement of the chain 102 will cause the engaging member 104 to engage the lever 63 which, through the link and lever 65 and .66 respectively, causes the gear 67 to mesh with the gear 68 and, through the sprockets 70 and 72 previously described, rotate the shaft 73, and, through the gears 74 and 83, cause the rotation of the shaft 34. The basket C at' this point, through the operation of the gear 84, is caused to move upwardly,the rollers 41 on the arm 40 travelling on the curved and inclined track 42. As the basket moves upwardly the projecting arm 49 will engage firstthe latchmember 47 and then the latch 48. The release of'the latch members permits the fingers 45 and 46 to almost completely span the open side of the basket G, this operation, of course, taking place before the basket has assumed a vertical position. Upon the basket reaching a vertical position, the untoothed portion of the gear 68 willhave reached engagement with the toothed portion of the gear 67. The gear 67 will therefore, through the action of the spring 107, be restored to a 1 normal position, the rollers 41 will be disengaged from the trackway 42, and the carriage 35 ready for rearward movement.

The front end of the basket is supported by lugs 108. The forward movement of the chain 102 will cause the member 104 to engage the lever 89 which will, through the link 91 and lever 92, cause the clutch member 82 to engage the gear 83, which, through-the 7 chain 84, causes the shaft 86 to rotate. The rotation of the shaft 86 moves the basket, which is mounted on the carriage, in a rearward direction. The principle in having the carriage moved vrearwardly is to overcome the forward speed of the binder so thatthe stock, during discharge and formation,

willbe stabilized. As thecarriage reaches the extremity of its rearward movement, the fingers 109to which are attached the springs 110, engage projections111 on the member 44, so that on reaching the rearward position the springs, indicated in Figure 6, have been expanded; The engaging arms 1.12 at this juncture engage the trip members 113, causing the member 44 to be released. On the release of this member it shoots backward and is supported by the rods 114. Simultaneous-with the forward movement of the member 44the ch'ain 115 is tensioned which, through the action of the pulleys 54, .55, 52 and 56, causes the-fingers 45 and 46 to resume their normal position and at the same time permit the sheaves to dropv in stoolsformation. The continued rotation of the shaft 86. w1ll reverse the direction of move ment ofthe'carnage, and. the carriage will therefore be returned to the extreme for.-

Ward position as illustrated in Figure 5. Upon reaching the forward extremity the bearing. 88 will engage the stop 116 which is connected to the lever 93 to cause the clutch member 82 to be disengaged.

During the forward travel of the basket, the member 44' slides back into the slot 48 and is locked therein by the latch member 112. The completion of the rearward movement of the carriage 85 will cause the arm 11? to engage the arm 118, to which is connected the lever 77 and through which the gear 67 is caused to mesh with the gear 75 which, meshing with the gear 76, transmits power to the shaft 69 and, through the previ ouslydescribed means and the shaft 23, to the gear 34 when the basket .travels down the position. Fi ure 9 is designed to equalize the movement of the arms 109 during tensioning or releasing of the springs 110.

It shouldbe noted with respect to the automatic operation of the sheaf shocker that suitable means such as a clutch operable from the drivers seat, could. be used to disengage the operating mechanism, so that in case, for example a small field of grain is encountered. the stook will not be deposited in an obstructed position. n
