Abstract
An apparatus and method for transferring the weight of a cutting edge blade to the top of a moldboard for alignment of the cutting edge blade to the moldboard is disclosed. The apparatus includes a roller member with a plurality of rotatably mounted guide rollers, a rigid arm with a hook for engaging the cutting edge blade, and a means of adjusting the roller member on the rigid arm.
Claims3
A method for transferring the weight of a cutting edge blade to a top of a moldboard, comprising the steps of:
- (a) engaging a cutting edge blade with a hook means of a rigid arm, which rigid arm is adjustably attached to a roller member, which roller member has a plurality of guide rollers rotatably mounted on a plurality of axles;
- (b) mounting the roller member on a top of a moldboard with the plurality of guide rollers resting on the top of the moldboard and the rigid arm with the engaged cutting edge blade abutting a concave side of the moldboard;
- and
- (c) rolling the roller member with the rigid arm and the engaged cutting edge blade along the top of the moldboard until the cutting edge is in alignment for attachment to the moldboard.
A method for transferring the weight of a cutting edge blade to a top of a moldboard, comprising the steps of:
- (a) engaging a cutting edge blade with a hook of a substantially C-shaped rigid arm, which C-shaped rigid arm is attached to a roller member, which roller member has a plurality of guide rollers rotatably mounted on a plurality of axles;
- (b) mounting the roller member on a top of a moldboard with the plurality of guide rollers resting on the top of the moldboard and the C-shaped rigid arm with the engaged cutting edge blade complementing and abutting a concave side of a moldboard;
- and
- (c) rolling the roller member with the C-shaped rigid arm and engaged cutting edge blade along the top of the moldboard until the cutting edge blade is in alignment for attachment to the moldboard.
An apparatus for transferring the weight of a cutting edge blade to a top of a moldboard, comprising:
- (a) a roller member which may roll along the top of the moldboard, said roller member having:
- (1) a frame supporting a plurality of axles which are rigidly attached in spatial relation;
- (2) a plurality of guide rollers, each of said guide rollers having a first cylindrical end having a radius R1, a second cylindrical end having a radius R2, an intermediate portion between the first and second cylindrical ends having a radius of R3;
- (3) a plurality of parallel ridges across the width of the frame complimentary to the width of a rigid arm for positioning and restricting movement of a rigid arm on the frame;
- (4) a bolt to support a rigid arm;
- and
- (5) a single wing-nut of complimentary size to the bolt;
- (b) a rigid arm hiving a hook means for engaging the cutting edge blade which rigid arm is positioned and attached to the roller member between the plurality of parallel ridges;
- (c) a means of adjusting the rigid arm on the roller member;
- and
- (d) the hook means provided on the same side of the rigid arm as the roller member for engaging the cutting edge blade.
