Scraper attachment for depth gauge wheel on seed planter
First Claim
1. A scraper for a depth gauge wheel of a type used on a seed planter, said depth gauge wheel being mounted by a pivot arm to a frame of the seed planter to permit movement of the depth gauge wheel in vertical and fore-and-aft directions, said scraper comprising:
- a scraper blade presenting an edge for removing debris from a recessed face of the depth gauge wheel;
an elongated arm mounting the scraper blade at a position to at least partially extend within the recessed face of the depth gauge wheel when the scraper is coupled therewith;
a mount for coupling the elongated arm with the depth gauge wheel and permitting relative rotative movement between the depth gauge wheel and the elongated arm to permit the arm to remain generally stationary as the depth gauge wheel rotates; and
a member for stabilizing the elongated arm at a position remote from said mount, said member presenting an elongated opening for receiving a support bolt and permitting sliding movement of the support bolt along said member when the scraper is mounted near the depth gauge wheel and said depth gauge wheel moves in a vertical or fore-and-aft direction.

Abstract
A scraper is provided for use on depth gauge wheels provided on planters for row crops such as corn, soybeans, cotton, beans, peanuts and the like. The scraper includes a scraper blade which is mounted at one end portion of an elongated arm for contacting the outer circumference of the depth gauge wheel and a second scraper blade that is mounted on the elongated arm at a position for preventing the accumulation of debris in the recessed well formed in the face of the depth gauge wheel. The other end of the arm is mounted by a bearing assembly to a hub provided on the depth gauge wheel. The bearing assembly is mounted coaxially with the axis of rotation of the wheel so that the arm remains stationary as the wheel rotates. In addition, the scraper blade remains in contact with the wheel as the wheel is moved in vertical and fore-and-aft directions. A support bolt is also received within an elongated opening presented by a U-shaped member mounted at the free end portion of the scraper arm to stabilize and reduce unnecessary movement of the scraper arm.

7. A scraper for a wheel used on a seed planter and mounted by a pivot arm to a frame of the seed planter to permit movement of the wheel in vertical and fore-and-aft directions, said scraper comprising:
-
an elongated arm; a mount for coupling the elongated arm with the wheel and allowing relative rotative movement between the wheel and the elongated arm to permit the arm to remain generally stationary as the wheel rotates; a first scraper blade mounted at an end portion of the elongated arm and presenting an edge for contacting an outer circumference of the wheel when the elongated arm is mounted on the wheel; a second scraper blade mounted at an intermediate portion of the elongated arm and having an edge extending within a recessed well of a face of the wheel when the elongated arm is mounted on the wheel; and a stabilizing member connected to the elongated arm at a position remote from the mount, said stabilizing member presenting an elongated opening for receiving a support bolt mounted on the frame of the seed planter and permitting sliding movement of the support bolt along said member when the scraper is mounted near the wheel and said wheel moves in either the vertical or fore-and-aft direction, whereby said first scraper blade is maintainable in contact with said outer circumference of the wheel as it moves in the vertical and fore-and-aft directions. - View Dependent Claims (8, 9, 10, 11)

12. A scraper in combination with a seed planter of the type having a frame mounting a plurality of seed hoppers, soil opening blades and a depth gauge wheel positioned by a pivot arm adjacent an opening blade, said depth gauge wheel being rotatable and being movable with said pivot arm about a pivot axis, said scraper comprising:
-
an elongated arm; a mount coupling the elongated arm with the wheel and allowing relative rotative movement between the wheel and the elongated arm to permit the am to remain generally stationary as the wheel rotates; a first scraper blade mounted at an end portion of the elongated arm and presenting an edge contacting an outer circumference of the wheel; a second scraper blade mounted at an intermediate portion of the elongated arm and having an edge extending within a recessed well of a face of the wheel; and a stabilizing member connected to the elongated arm at a position remote from the mount, said stabilizing member presenting an elongated opening receiving a support bolt mounted on the frame of the seed planter and permitting sliding movement of the support bolt along said member when the wheel moves in either the vertical or fore-and-aft direction, whereby said first scraper blade is maintained in contact with said outer circumference of the wheel as it moves in the vertical and fore-and-aft directions. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
