Abstract
Abstract Apparatus for punch planting of seeds comprising a slotted-rimmed wheel rotatably mounted on a frame with an axis of rotation passing through the center of a gear fixed to the frame. The wheel is equipped with a plurality of drive gears which communicate with and rotate around the fixed gear. On each drive gear is pivotally mounted a magnetic-tipped punch. The rotation of the wheel causes the punches to move in and out of the slots in the wheel. The action of the punch produces a small hole in the soil and embeds a coated seed therein.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
197 words
A device for planting seeds, comprising in combination - a. a frame, b. a fixed gear mounted on said frame, c. a wheel with a concave rim rotatably mounted on said gear and having an axis of rotation passing through the center of said fixed gear, the rim of said wheel containing a plurality of slots located at the deepest point therein, d. a plurality of drive gears rotatably mounted on said wheel and planetarily arranged around and communicating with said fixed gear, each drive gear equipped with a punch pivotally mounted thereon and cooperating with said wheel and said fixed gear such that the rotation of said wheel causes the punches to move in and out of the wheel through the slots therein and such that the punches are fully extended when they are perpendicular to and when they are parallel to the soil surface and fully retracted when they are at points midway between perpendicular and parallel, each of said punches containing a magnetic tip, and e. a seed box, filled with seeds coated with a magnetic attracting substance, mounted on said frame at a position which allows distribution of the seeds to said punches.
Claim 2
Independent Claim

A device for planting seeds, comprising in combination - a. a frame, b. a fixed gear mounted on said frame, c. a wheel with a concave rim rotatably mounted on said gear and having an axis of rotation passing through the center of said fixed gear, the rim of said wheel containing a plurality of slots located at the deepest point therein, d. a plurality of drive gears rotatably mounted on said wheel and planetarily arranged around and communicating with said fixed gear, each drive gear equipped with a punch pivotally mounted thereon and cooperating with said wheel and said fixed gear such that the rotation of said wheel causes the punches to move in and out of the wheel through the slots therein and such that the punches are fully extended when they are perpendicular to and when they are parallel to the soil surface and fully retracted when they are at points midway between perpendicular and parallel, each of said punches containing a magnetic tip, and e. a seed box, filled with seeds coated with a magnetic attracting substance, mounted on said frame at a position which allows distribution of the seeds to said punches.
Claim 3
Dependent Claim
52 words
The device of claim 1 wherein the distance between the perimeter of said wheel and the axis of rotation thereof, the circumference of said fixed gear, and the circumference of said wheel are coordinated such that punches are always perpendicular to the soil surface as they enter and retract from the soil.
Claim 4
Dependent Claim
19 words
The device of claim 1 wherein the number of said drive gears is determined by the desired plant spacing.
Claim 5
Dependent Claim
27 words
The device of claim 1 wherein the number of slots in the rim of said wheel is equivalent to the number of punches on said drive gears.
