Abstract: 16,757. Calder, J. July 29. Sheafing or binding apparatus.-In a shocking- attachment for harvesters, the sheaves are discharged from the binder on to a sheaf-carrier which delivers them periodically into a receptacle where they are bound together to form a shock, which is discharged in an upright position with its butt end on the ground. The attachment is supported by the braced binder frame A and a wheel H. The main shaft 2 is driven continuously from the shaft J by means of the chain 5, and drives sprocket-wheels 39, 50, loose on shafts 35, 48, by means of a chain 40. The shock receptacle consists of two gates 26, 27 pivoted on a frame 24 and normally held in the position shown by spring- controlled catches 28. When two or more sheaves have collected on the table 42, the first one presses against a trip-lever, which causes a spring-controlled dog to engage a clutch connected with the sprocket-wheel 39, and allows the shaft 35 to revolve. This causes the sheaf-carrier 42 to move forward and deposit the sheaves in the receptacle, springs being provided to push the sheaves off. The table 42 slides on guides and is moved by pivoted and slotted rods 43 connected with the shaft 35 by rods 45 and cranks 41. When a certain number have been deposited in the receptacle, a projection on a disc on a countershaft 69, which is driven from the shaft 35 by means of a chain 68, moves a spring and allows a dog to engage with a clutch connected with the sprocket-wheel 50, and thus rotates the knotter shaft 48. This shaft is connected, by means of cranks and a connecting- rod 53, with the needle 55, which is thus brought down into action. The pivoted needle arm 56 is connected, by means of a rod 62 and crank 61, with a shaft carrying a curved arm 60. This arm engages a plate 64 and forces down the compressor arms 63 against the action of a spring 65, the arms being then locked by the action of a spring which presses a perforated disc against a projection on one of the arms. When the shock has been bound, it is discharged by the revolution of a shaft 8<a>, which is driven from the main shaft 2 by bevelwheels 6, 7, a shaft 8, and a clutch 10 operated from the knotter shaft 48. The shock receptacle is carried by pairs of pivoted levers 14, 15, 18, 19, which are connected with cranks on the shaft 8<a> by rods 13, 17. The revolution of the shaft causes the receptacle to tilt into a vertical position, when the catches 28 are released by coming into contact with fixed projections 32, and the gates 26, 27 are forced open by springs. The continuation of the rotation of the shaft 8<a> returns the compressor and receptacle to their normal position, the arms 63 having been released by a projection on a rod connecting the catches 28. The gates are closed by contact with fixed converging rods 108, 109. The sheaf-carrier is provided with spring-controlled arms 74, which are depressed by the sheaves as they pass on to the table 42 and then return to their normal upright position. The knotter frame is adjusted by means of a rocking shaft E and connecting-rod 78. Fig. 5 shows the clutch mechanism connecting the shafts 8, 8<a>. The shaft 8<a> rotates when the catch of a spring-controlled dog 97, pivoted on a collar 96, is released by a projection 72, Fig. 1, on the shaft 48 striking against a pivoted lever 71. The slotted trip 98 slides on pins 100 and is controlled by a spring 101. When the shaft 8<a> has made half of a revolution, the catch of the dog 97 engages the trip 102 and momentarily disengages the dog from the clutch 10. The trip 102 is disengaged from the dog by a lip 106 on the clutch, the trip being slotted to slide on pins 104 and controlled by a spring 105.
