Adjustable depth control mechanism for earth-penetrating disk
First Claim
1. A hub and spindle assembly adapted to be mounted on a support axle of an earth-penetrating piece of equipment having a generally "I" shaped in cross-sectional depth gauge wheel and a disc through which the support axle passes, said assembly comprising:
- an adjustment plate having a plurality of non-circular apertures, said plate being adapted for mounting on the support axle in non-rotatable relation;
a position adjustment arm adapted for mounting on the support axle and relatively rotatable with respect thereto;
said arm having a first end with a pin receiving hole adapted to be aligned with any of said apertures in said adjustment plate;
a spindle shaft parallel to and laterally spaced from the support axle;
an adjustment pin having a first non-circular end, adapted to be positioned in one of said apertures in said adjustment plate, and a second end, said pin being concentric with said spindle shaft and passing through the spindle shaft;
a means for indicating the relative position of the depth gauge wheel relative to the disc, said means for indicating position being attached to said second end of said adjustment pin.

Abstract
An adjustable depth control mechanism for use with earth penetrating equipment. The invention includes a hub and spindle assembly for use with an adjustable depth gauge wheel, which is mounted on a support axle. It may also include a position indicator that an operator can readily view to determine the relative position of the depth gauge wheel and, accordingly, the depth setting of the ground penetrating disc. The indicator rotates to certain positions that correspond to the depth to which the disc is allowed to penetrate into the ground. Preferably, both the position indicator and the adjustment mechanism of the assembly are located internal to the depth gauge wheel and are covered and protected by the rim of the wheel from contamination by soil and crop residue.

7. An adjustable depth control mechanism for a disc that selectively changes the relative orientation between a disc and a depth gauge wheel to control the depth of penetration of the disc into the ground, said mechanism comprising:
-
a support axle; a disc rotatably mounted on said support axle; an adjustment plate defining a plurality of non-circular apertures therein;
said plate mounted on said support axle in non-rotatable relation thereto;a position adjustment arm having a pin receiving hole formed there through;
said pin receiving hole adapted to align with said non-circular apertures;
said arm being mounted on said support axle and relatively rotatable with respect thereto;an adjustment pin having a non-circular end that passes through said pin receiving hole in said position adjustment arm and engages one of the non-circular apertures in said adjustment plate and having a second end opposite the non-circular end; a spindle shaft parallel to and laterally spaced from said support axle;
said spindle shaft concentric with said adjustment pin;a depth gauge wheel rotatably mounted on said spindle shaft;
said wheel defining a central radially extending wall and a wheel rim having first and second flange members laterally extending in opposite directions from said central wall, whereby said adjustment plate and said position adjustment arm are mounted adjacent to said central wall and are covered and protected by one of said flange members;a handle attached to said adjustment pin for adjusting the orientation between said disc and said depth gauge wheel. - View Dependent Claims (8, 9, 10, 11)

12. An adjustable depth control mechanism for a ground penetrating assembly including:
-
a support axle adapted to be connected to a frame; a ground penetrating disc rotatably mounted on said support axle; a position adjustment arm mounted on said support axle and rotatable relative thereto; a spindle shaft extending from said position adjustment arm parallel to, but laterally displaced from said support axle; a depth gauge wheel rotatably mounted on said spindle shaft; an adjustment plate mounted on said support axle and non-rotatable with respect thereto defining a plurality of apertures therein; an adjustment pin engagable with any of said apertures in said adjustment plate and extending through said position adjustment arm, said position adjustment arm being movable with respect to said adjustment plate; position indicator means connected to said adjustment pin for linear and rotational movement thereof; whereby relative movement of said position adjustment arm with respect to said adjustment plate effects a change in position of said depth gauge wheel relative to said disc thereby changing the permitted depth of penetration of said disc. - View Dependent Claims (13)
