Title: Improvements in or relating to agricultural implements
IPC: A01B3/421
Filed: 1950-04-05
Abstract: 730,001. Agricultural implements. FERGUSON, Inc., H. April 5, 1950 [April 5, 1949], No. 8591/50. Class 6 (1). A one-way plough is supported on power operated upper and lower hitch links 22, 23 respectively and comprises a pair of plough bodies supported on a rotatable beam 60 which is rocked through 90. degrees in opposite directions, to position the plough bod-. ies, as an incidence to raising the beam to a transport position by means of the power operated links. As shown the plough bodies are adjustably bolted to a head welded to the beam 60, the beam rotating in bearings on a casing 65 which is attached to the hitch links. A locking element 62 is fixed to the beam 60 and an actuator lever 101 is rotatably mounted on'the shaft 107 of a cam 103 fixed to the beam 60. A chain 110, fixed by a swivel 113 to a loose shackle 114 attached to a rod 115 rigidly mounted on the tractor, is attached to a member 111 extending through and secured for sliding movement in a slot 112 in lever 101. A coulter 85 is adjustably mounted on shaft 86 rotated in bearings 88 in the casing 65 and fingers 121 on the element 62 co-operate with abutments 122 on the coulter assembly to move the coulter transversely on rotation of the beam so that it may operate with either plough body. A spring 102 is connected between the coulter assembly and the lever 101. When the hitch links are raised the shackle 114 restrains the chain 110 and moves the member 111 in the slot 112 to depress a spring-urged plunger 119 andrelease a detent 79, pivoted on the casing 65, from engagement with a slot 77 on a flange 75 of element 62. Further movement of the hitch links causes the lever 101 to rotate the beam 60 by engagement of the lever with abutment 104 or 105 on the flange 75 until the detent 79 engages the slot 77 to look the beam in position. When tension on the chain is released by lowering the machine into working position. the lever 101 is returned to its starting position by means of spring 102. To ensure that the lever 101 is biased in a direction to ensure correct rotation of the beam, a spring urged plunger 134 engages in slots 132, 133 in cam 103. The movement of the coulter assembly on rotation of the beam moves the spring 102 to bias the lever 101. To raise the machine without rotating the beam, a hand operated cam 117 depresses member 111 and the plunger 119 engages against the side of detent 78 preventing lever 101 reaching its position against abutment 104 or 105. In a modification the coulter may be dispensed with. The tractor may be provided with a power lift mechanism as described in Specification 470,069 and the plough bodies are provided with furrow wheels which may be as described in Specification 470,068. Specifications 510,352 also is referred to. Reference has been directed by the Comptroller to Specification 544,041.
