• a two part adjustable shaft is extended from the stub shaft S-l, the two part adj ustable shaft including the rod 63 connected by one end with the stub shaft 34 by means of a universal joint 64, as shown clearly in Fig. 2.
• the sleeve 65 of the adjustable shaft is adapted to slide longitudinally over. the other end of therod 63 and connects by means of a universal joint 66, with stub shaft 67 which is adapted to be rotated in the bearing members 68 carried on the upper. side of the turn-table 40.
• Bearing members 69 are extended laterally from the stub shaft 67, between the bearing members 68 and are pivotally connected with a lateral extension 70 of a bearing collar 71, which is loosely engaged around the supporting rod 72, which latter is mounted transversely above the turn-table 40.
• Stop collars 73 are carried on the supporting rod 72 on opposite sides of the bearing collar 71 to prevent movement of the latter longitudinally of the supporting rod 72.
• An upstanding bearing member 74 is mounted on the turn-table 40 at a point diametrically opposite the bearing members 68.
• the supporting rod 72 is loosely engaged through the bearing member 74 and a spiral groove 75 is provided in the supporting rod 72 to receive a pin carried in the bearing member 74- to cause rotation of the supporting rod 72 as the latter is moved longitudinally through the bearing member 74, by operation of the stub-shaft 67, as should be apparent from Fig. 9.
• One half or section 7 6 of the sheaf receiver is mounted on the end of each supportin rod 72 extending into the open space in the center of the supporting frame.
• Fig. 1 it will be noted that the supporting rods '72 are shown as being in alignment and the parts or sections 76 of the sheaf receiver as being brought together at their lower side. It will also be seen clearly from this view, in connection with Figs. 2, 6 and 7, that the parts or sections 76 of the sheaf receiver are of substantially semi-circular form in cross section and tapered toward one end. They are also positioned on the supporting rods 72 in such a manner that their upper longitudinal. edges are spaced apart, while their lower longitudinal edges overlap, when the receiver is in the horizontal or receiving position, as shown in Fig. 1.
• the frame 5 may be suitably supported in any desired manner from the side of a binder so that the sheaf receiver may be under the discharge portion of the side of the binder to permit the sheaves to drop into the sheaf receiver.
• the operator should pull the lever operating cable 62, thereby operating the releasing lever 60 and raising the locking bar 51 from engagement with the locking pin 48.
• the spring 23 operates to throw the clutch member 22 into engagement with the clutch member 21, thereby locking the shaft 19 for rotation with the sprocket wheel 17 and sleeve 18 carrying the clutch member 21. This permits the gear wheel 24 to rotate the gear wheel 26 on each side of the machine, thereby causing rotation of the longitudinal side shafts 27 in the proper directions.
• the bevel gears 28 carried on the longitudinal side shafts 27 will register with the gear wheel 29 on the vertical shaft 30 and rotate the latter together with the longitudinal side shaft 27 and thus cause the vertical shaft 30 torotate the stub shaft 34 through the medium of the gear wheels 32 and 83 carried on the vertical shaft 30 and the stub shaft 34, respectively.
• This will result in turning the l11811'll3G'1'S 63 to 6'? inclusive and thereby moving the supporting rod 72 longitudinally and rocking the same in the bearing member 74.
• the cams 39 are sufficiently turned so that their flat sides are under the turntables 40, thus allowing a sudden drop to the turn-tables 40 so that the sheaves of grain are driven into the stubble as they are deposited on the surface and released from the sheaf receiver 'to. form a stock.
• the shaft 19 continues to rotate and the gear wheels operate in turn on the gear wheel 47, rotating the lat ter with the drum 45 and drum shaft 46 in first one direction and then the other.
• the ends of the cables 44 are wound upon the drum 45, thereby rotating the turn-tables in the direction iii-- dicated by the arrows.
• the locking pin 48 will have made a complete revolution with the drum 45 and drum shaft 46 and will return to the slot 49 in the end of the locking bar 51.
• the operator should again pull the operating cable 62 for the releasing lever and thereby again release the locking pin 48 from the slot 49 so as to permit action of the other gear wheel 25 on the gear wheel 47 to cause rotation of the drum 45 and the drum shaft 46 in the reverse direction.
• the cables 44 will be operated'to reverse the rotation of the turn-tables 40 and bring them back to normal position.
• the clutch members 21 and 22 are engaged during this second operation of the shaft 19, the longitudinal side shafts 27 are again rotated with the shaft 19. This second rotation of the longitudinal side shafts 27 will cause the gear wheels 28' thereof to operate oppositely on the bevel gears 29 of the vertical shafts 30.
• a stooker consisting of a frame, wheels supporting said frame, a shaft transversely positioned at the forward end of said frame, a loosely mounted sprocket wheel on one end of said shaft, a sprocket carried byone of said supporting wheels, a sprocket chain connecting said sprocket with said loosely mounted sprocket wheel, tables pivotally mounted on said frame, means for raising said tables, means for turning said tables, supports carried by said tables, rods carried by said supports, a sheaf-receiving member carried at the inner end of each of said rods, means for ope-rating said rods.
