Title: Tractors or like agricultural vehicles provided with power lift mechanisms
Inventor: HAYWARD STUART LESLIE
IPC: A01B63/111
Filed: 1963-12-19
Abstract: 1,102,959. Tractor power lift mechanisms. DOWTY HYDRAULIC UNITS Ltd. 8 Dec., 1964 [19 Dec., 1963], No. 50190/63. Heading A1P. A tractor power lift mechanism incorporating draft control is characterized in that pressure fluid for the hydraulic circuit is supplied by two pumps in a common casing 50. The pumps can be used independently or together and are controlled by a pump selector 58. As shown, the mechanism is set for draft control, the pump 53 providing pressure fluid through conduits 59 and 108 and the pump 54 being connected to reservoir through conduits 60 and 91. Pressure in the conduit 116 leading to the ram cylinder is controlled by a flow divider 109, the pressure fluid in this conduit passing to reservoir via conduit 115 and holes 124 in the main valve 94. These holes are throttled internally by a piston 122 moved in response to draft changes by a rod 49 coupled to the upper link 25 by a lever 46. Thus fluid is supplied or exhausted from the ram in response to movements of the upper link 25 after the draft load has been initially set by lever 56. For position control the lever 56 can be moved sideways whereby a follow-up lever 42 is brought into engagement with rod 49 and lever 46 is moved away. Movement of lever 56 and therefore the valve 94 to the right in the Figure then operates to block off the holes 124 so that pressure fluid is supplied to the ram until the follow-up linkage is moved to operate piston 122 to open the holes 124. If lever 56 is moved to the 'neutral' position shown in the drawings, the operator, by shifting the lever 56 in the directions indicated for lowering or raising, has complete manual control over the mechanism with no follow-up action. In this case, with the levers 57 and 58 in the positions shown, the spool 94 is moved to the right to close the outlet to reservoir from conduit 91 and to close the outlet to the ram from conduit 108 through the flow divider 109. Thus both the pumps 53 and 54 feed respectively through conduits 108 and 91 to conduit 111 and thence to the spool at 106. In the neutral position this pressure is fed through the holes 94a to reservoir but movement of the spool in the 'raise' direction communicates this output to the conduit 114 feeding the ram and in the 'lower' direction communicates conduit 114 with the reservoir via holes 94a. For a slower lifting operation the pump 54 can be isolated from the ram circuit by movement of rod 58 to position 'c'. In this position the pump 54 feeds to reservoir through conduit 76 and 79 a in the external supply control spool 79. Movement of this spool by lever 57 connects this supply with an external circuit through conduit 87 and outlet 89. By manipulation of the rod 58, only the pump 53, or both pumps 53 and 54 can be made to supply this external circuit. A further external circuit can be operated through conduit 117 after the lifting ram has been mechanically locked.
