Abstract
Abstract The present invention is generally useful in supplying fluent materials to the surface of the earth and has primary utility for planting grains, such as wheat, over grassland to provide winter pasture for livestock. In one form, apparatus embodying certain features of this invention may include a rectangular frame having a longitudinal axis and a front and a rear end. A plurality of earth-cutting means, such as disks, may be mounted underneath the frame adjacent the front end thereof with each of the disks aligned along an axis mounted at an angle to the longitudinal axis of the frame. A reservoir, such as a seed and fertilizer box, may be provided, preferably above and adjustable longitudinally with respect to the front gang of disks, and a plurality of channel means, such as seed and fertilizer tubes, may be provided extending from the lower portion of the seed box to a position near and above the lower edge of the disks. Means for pressing the seeded furrows may be provided adjacent the rear end of the frame; and in a preferred embodiment such furrowpressing means may comprise a plurality of aligned disks, each of which is offset in its relationship to a corresponding disk in the front disk gang. Ground support means, such as a plurality of fluid filled tires, depend from the frame at an intermediate position on the frame between the front disk gang and the furrowclosing disks. Means are provided to adjust the relative vertical position of the front disk gang and the furrow closing disks around the ground support mean. In addition, as an optional feature of this invention there may also be provided an outrigger assembly extending from the rear end of the frame for minimizing side drift of the apparatus.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
222 words
A drill comprising; a. a frame having a longitudinal axis and a front and a rear end; b. a plurality of earth-cutting means mounted below and adjacent the front end of said frame, said earth-cutting means being aligned along an axis at an angle to the longitudinal axis of the frame; c. a reservoir situated on said frame above said plurality of earth-cutting means; d. a plurality of vertical channel means communicating with the interior of the reservoir near the bottom thereof, the lower end of each of said channel means being disposed to position material from the reservoir immediately behind an earth-cutting means; e. furrow-pressing means mounted on said frame near the rear portion thereof in a position to close furrows opened in the earth by said earth-cutting means; f. vertically adjustable ground support means located on said frame intermediate the earth-cutting means and the furrowclosing means; g. hitch means pivotally secured to said frame near said front end, said hitch means being provided at its end nearest said frame with a vertically offset connection means; and h. tilt-adjusting means pivotally and operatively connected from said offset connection means to a location on said drill, said location being offset vertically and longitudinally from said offset connection means, to adjust the relative vertical position of the earth-cutting means and the furrow-pressing means.
Claim 2
Dependent Claim
222 words
A drill comprising; a. a frame having a longitudinal axis and a front and a rear end; b. a plurality of earth-cutting means mounted below and adjacent the front end of said frame, said earth-cutting means being aligned along an axis at an angle to the longitudinal axis of the frame; c. a reservoir situated on said frame above said plurality of earth-cutting means; d. a plurality of vertical channel means communicating with the interior of the reservoir near the bottom thereof, the lower end of each of said channel means being disposed to position material from the reservoir immediately behind an earth-cutting means; e. furrow-pressing means mounted on said frame near the rear portion thereof in a position to close furrows opened in the earth by said earth-cutting means; f. vertically adjustable ground support means located on said frame intermediate the earth-cutting means and the furrowclosing means; g. hitch means pivotally secured to said frame near said front end, said hitch means being provided at its end nearest said frame with a vertically offset connection means; and h. tilt-adjusting means pivotally and operatively connected from said offset connection means to a location on said drill, said location being offset vertically and longitudinally from said offset connection means, to adjust the relative vertical position of the earth-cutting means and the furrow-pressing means.
