Abstract
Abstract The improved planting machine of the invention, which prepares a hole in the soil for a plant to be inserted therein, and thereupon places the plant in said hole and firms the soil about it, is characterized in that the machine has a planting member so actuated that during the act of planting the plant said member temporarily stands still in relation to the soil whilst the planting machine as a whole advances at its normal rate.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
188 words
A planting machine having at least one liftable and lowerable planting member for dropping a plant, held therein, into a hole in the ground by the planting member, said planting member in its position lowered into the soil standing still in relation to the soil during the normal advancing movement of the machine, characterized in that the planting member (15) is slidably mounted on and movable along an essentially straight arm means (16) extending in the longitudinal direction of the machine, said arm means being pivotally mounted on said machine for movement in a vertical plane; means for moving said arm means at least in an essentially vertical plane around said pivot (20) in front of the planting member from a position substantially in parallel with the soil, in which position the planting member is kept lowered into the soil and standing still in relation to the soil through the act of the relative mobility between the planting member and the arm means, to a position inclined obliquely forward to the soil for lifting and repositioning the planting member to its starting position on the arm means (16).
Claim 2
Dependent Claim
188 words
A planting machine having at least one liftable and lowerable planting member for dropping a plant, held therein, into a hole in the ground by the planting member, said planting member in its position lowered into the soil standing still in relation to the soil during the normal advancing movement of the machine, characterized in that the planting member (15) is slidably mounted on and movable along an essentially straight arm means (16) extending in the longitudinal direction of the machine, said arm means being pivotally mounted on said machine for movement in a vertical plane; means for moving said arm means at least in an essentially vertical plane around said pivot (20) in front of the planting member from a position substantially in parallel with the soil, in which position the planting member is kept lowered into the soil and standing still in relation to the soil through the act of the relative mobility between the planting member and the arm means, to a position inclined obliquely forward to the soil for lifting and repositioning the planting member to its starting position on the arm means (16).
Claim 3
Dependent Claim
181 words
A planting machine including a frame-supporting vehicle adapted for movement over the ground, said planting machine comprising arm means reciprocatingly secured on said frame and extending in the longitudinal direction of the machine, said arm means including a carriage mounted on and reciprocatable along said arm means; a source of plants on said planting machine; at least one liftable and lowerable planting member carried on said carriage, said planting member comprising means for opening a hole in the ground and dropping a plant, held therein, into the hole, said plant having been fed into said hole-opening means by an operator; said arm means being movable about a point in front of said planting member from a position substantially in parallel with the ground to a position inclined obliquely forward with respect to the ground; and means for translating said carriage with its planter member forwardly and downwardly and rearwardly and upwardly, whereby to force an end of said planting member into the ground and with it forming a hole in the ground and dropping a plant into the hole so formed.
Claim 4
Dependent Claim
181 words
A planting machine including a frame-supporting vehicle adapted for movement over the ground, said planting machine comprising arm means reciprocatingly secured on said frame and extending in the longitudinal direction of the machine, said arm means including a carriage mounted on and reciprocatable along said arm means; a source of plants on said planting machine; at least one liftable and lowerable planting member carried on said carriage, said planting member comprising means for opening a hole in the ground and dropping a plant, held therein, into the hole, said plant having been fed into said hole-opening means by an operator; said arm means being movable about a point in front of said planting member from a position substantially in parallel with the ground to a position inclined obliquely forward with respect to the ground; and means for translating said carriage with its planter member forwardly and downwardly and rearwardly and upwardly, whereby to force an end of said planting member into the ground and with it forming a hole in the ground and dropping a plant into the hole so formed.
Claim 5
Dependent Claim
19 words
A planting machine as defined in claim 2, characterized in that the planting member is a generally cylindrical dibble.
Claim 6
Dependent Claim
51 words
A planting machine as defined in claim 3, in which two slide covers are provided for closing the downwardly open end of the planting dibble, characterized in that the two slide covers are coupled together one to the other by means of links for simultaneous movement from closed to open position.
Claim 7
Dependent Claim
28 words
A planting machine as defined in claim 2, characterized in that the planting member at its lower end is closable by means of at least one slide cover.
Claim 8
Dependent Claim
33 words
A planting machine as defined in claim 5, characterized in that each slide cover is provided with a shoulder projecting in closed position of the cover in the extension of the planting member.
Claim 9
Dependent Claim

Claim 10
Dependent Claim
38 words
A planting machine as defined in claim 7, characterized in that the downfeed pipe is closable by a cover adapted to be moved to open position by the planting member and to closed position by a return means.
Claim 11
Dependent Claim
31 words
A planting machine as defined in claim 2, further comprising a return means, mounted on said frame for returning the carriage to and retaining it in starting position on the arm.
