Abstract

A tilt bucket may include a front structure having an outer surface, the front structure including a base plate with a bottom surface. The tilt bucket may include a bottom edge and a curved wrapper extending between the base plate and the bottom edge. A ratio of a maximum distance between the curved wrapper and a first line extending from the bottom edge to the tangent point on the outer surface of the front structure, taken substantially perpendicularly from the first line, relative to a length of the first line, may be about 0.64 to 0.70.

First claim

What is claimed is:

1. A tilt bucket, comprising:
a top section including a front structure;
a bottom section including a bottom edge; and
a middle section including a wrapper, the wrapper extending between the front structure and the bottom edge;
wherein the front structure includes:
a base plate attached to the wrapper;
a boxed section adjacent a first end portion of the base plate;
a first tilt plate attached to the boxed section; and
a second tilt plate attached adjacent a second end portion of the base plate wherein the boxed section includes a bent plate attached to the base plate, and a support plate extending between the base plate and the bent plate, and wherein the bent plate is attached to the base plate approximately 20 mm from a first end of the bent plate, and the bent plate is attached to the support plate approximately 10 mm from a second end of the bent plate.

2. The tilt bucket of claim 1 , wherein the support plate is substantially parallel to a first portion of the bent plate, and the base plate is substantially parallel to a second portion of the bent plate.

3. The tilt bucket of claim 2 , wherein the distance between the support plate and the first portion of the bent plate is approximately 65 mm or greater, and the distance between the base plate and the second portion of the bent plate is approximately 107 mm or greater.

4. The tilt bucket of claim 2 , wherein the first tilt plate extends substantially perpendicularly from the second portion of the bent plate and parallel to the support plate and the first portion of the bent plate.

5. The tilt bucket of claim 4 , wherein the first tilt plate is offset from the support plate by a distance of 15 mm or greater.

6. The tilt bucket of claim 5 , wherein the first tilt plate is offset from the support plate by a distance of between 15 mm and 25 mm.

7. The tilt bucket of claim 2 , wherein the ratio of the distance between the support plate and the first portion of the bent plate to the distance between the base plate and the second portion of the bent plate is between 0.5 and 1.0.
