Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 162 words
A digging and planting machine comprising, in combination, a vehicle, and, carried on the vehicle, a tubular digging and planting tool having an open digging and planting tip end for digging a hole and conveying a plant to the hole; means for compacting earth about the plant after it has been deposited in the hole; means for moving each of the digging and planting tool and the compacting means separately, between ground-elevated and ground-contacting positions; and means for moving the digging and planting tool and the compacting means together between ground-elevated and ground-contacting positions; the digging and planting tool being reciprocably mounted on the compacting means for movement towards and away from a ground-contacting position for digging a hole for a plant to be transferred from the machine, and the compacting means being reciprocably mounted on the vehicle, for movement towards and away from a ground-containing position for compacting earth about the plant simultaneously with withdrawal of the digging and planting tool.
Claim 2
Dependent Claim 162 words
A digging and planting machine comprising, in combination, a vehicle, and, carried on the vehicle, a tubular digging and planting tool having an open digging and planting tip end for digging a hole and conveying a plant to the hole; means for compacting earth about the plant after it has been deposited in the hole; means for moving each of the digging and planting tool and the compacting means separately, between ground-elevated and ground-contacting positions; and means for moving the digging and planting tool and the compacting means together between ground-elevated and ground-contacting positions; the digging and planting tool being reciprocably mounted on the compacting means for movement towards and away from a ground-contacting position for digging a hole for a plant to be transferred from the machine, and the compacting means being reciprocably mounted on the vehicle, for movement towards and away from a ground-containing position for compacting earth about the plant simultaneously with withdrawal of the digging and planting tool.
Claim 3
Dependent Claim 30 words
A digging and planting machine in accordance with claim 1, comprising a depth indicator on the digging and planting tool, signalling when a hole of predetermined depth has been dug.
Claim 4
Dependent Claim 21 words
A digging and planting machine according to claim 1, having the digging and planting tool reciprocably mounted within the compacting means.
Claim 5
Dependent Claim 21 words
A digging and planting machine according to claim 1, having the digging and planting tool reciprocably mounted outside the compacting means.
Claim 6
Dependent Claim 42 words
A digging and planting machine according to claim 1, in which the digging and planting tool is a tube having a digging tip end extending at an angle of less than 45° to the axis of the tube, with a sharp tip.
Claim 7
Dependent Claim 46 words
A digging and planting machine according to claim 1, in which the digging and planting tool is arranged to be inserted into the ground along a path directed obliquely downwards and forwards in the direction of movement of the vehicle carrying the digging and planting machine.
Claim 8
Dependent Claim 56 words
A digging and planting machine according to claim 6, in which the digging tool is a tube having a central passage through which plants can be fed to a hold dug by the tool, and the tip of the digging tool is placed so that the leading side is solid tube, and an opening faces rearwardly.
Claim 9
Dependent Claim 62 words
A digging and planting machine in accordance with claim 1, in which the open digging and planting tip end of the digging and planting tool comprises closure means movable between a first position closing off the open end for digging a hole, and a second position exposing the open end for delivery of a plant from the planting tool into the hole.
Claim 10
Dependent Claim 85 words
A digging and planting machine according to claim 8 having coupling means connecting the compacting means, the digging and planting tool, and the closure means, in a manner such that when the closure means is moved in one direction, towards the closed position, the compacting means and the digging and planting tool are coupled to move together, and when the closure means is moved in the other direction, towards the open position, the digging and planting tool and compacting means are uncoupled, to move separately.
Claim 11
Dependent Claim 23 words
A digging and planting machine according to claim 8, in which the digging tool is straight and the closure means a curved plate.
Claim 12
Dependent Claim 25 words
A digging and planting machine according to claim 9, in which the coupling means comprises a pawl pivotable into and away from a coupling position.
Claim 13
Dependent Claim 24 words
A digging and planting machine according to claim 8, comprising piston means for moving the closure means between tip end-open and tip end-closed positions.
Claim 14
Dependent Claim 17 words
A digging and planting machine according to claim 12, in which the closure means is a plate.
Claim 15
Dependent Claim 23 words
A digging and planting machine according to claim 8, in which the digging tool is arcuate and the closure means a curved plate.
