FIG. 1 is a side plan view of the excavator blade constructed in accordance with the teachings of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The preferred embodiment, an excavator blade generally identified by reference numeral 10, will now be described with reference to FIG. 1 through 3.
Structure and Relationship of Parts:
Referring to FIG. 1, excavator blade 10 includes a mounting 12 including mounting plate 13 and a blade 14. Blade 14 extends downwardly from mounting 12 at an angle of 45 degrees, but preferably between 40 degrees and 50 degrees. Referring to FIG.
The preferred embodiment, an excavator blade generally identified by reference numeral 10, will now be described with reference to FIG. 1 through 3.
Structure and Relationship of Parts:
Referring to FIG. 1, excavator blade 10 includes a mounting 12 including mounting plate 13 and a blade 14. Blade 14 extends downwardly from mounting 12 at an angle of 45 degrees, but preferably between 40 degrees and 50 degrees. Referring to FIG.
3, blade 14 has a mounting attachment end 16, a ground piercing end 18, and opposed upstanding sidewalls 20. Referring to FIG. 2, sidewalls 20 may angle outwardly from blade 14, such by an outward bend of between 10 and 45 degrees. As sidewalls 20 extend upward and outward, it is easier to remove soil from blade 14 during digging. Getting the dirt out of buckets or blades is a particular concern in wet clay or sticky mud. If wet clay or mud is being dug, it may also be preferable to have shorter sidewalls 20. To improve the ground piercing capability of blade 14, teeth 22 may project forward from ground piercing end 18. Referring again to FIG. 1, blade 14 has a forward oriented bend 24 at an angle of 20 degrees, but preferably between 15 degrees and 25 degrees. As depicted, sidewalls 20 slope downwardly from bend 24 to ground piercing end 18, such that sidewalls 20 are negligible at ground piercing end 18. Bend 24 is spaced from ground piercing end 18 approximately one third of the way along blade 14. The length of blade 14 from attachment end 16 to ground piercing end 18 is greater than five times the width of blade 14 between sidewalls 20.
While the word "blade" is used in this document to describe the excavator, the term "bucket"
could equally be used.
Operation:
Excavator blade 10 is attached to a prime mover, such as a back hoe, by mounting 12.
Excavator blade 10 is inserted and moves through the ground based primarily on the horizontal pulling force pulling toward the prime mover (not shown) to provide the necessary force to excavate. Teeth 22 help ground piercing end 18 to break and pass through the soil.
The soil is then pushed in an upward sliding motion along blade 14 from ground piercing end 18 toward attachment end 16. Once blade 14 is filled, the horizontal distance in the ditch that has been excavated corresponds approximately to the length of the bucket. A
ditch is thus dug by taking a series of slices from the ground, until the desired depth is reached. The bucket is then lifted out of the ditch with blade 14 in a horizontal position to remove the soil.
Side walls 20 act to keep the dirt within blade 14.
Variation:
Referring to FIG. 4, instead of blade 14 having a single bend 24 as depicted in FIG.
1, blade 14 could also be formed as a continuous bend that begins at attachment end 16 and continues until ground piercing end 18, or that includes a substantial portion of blade 14. If this were done, it would be a tangent taken at a point partway along blade 14 that would be at 45 degrees, and a tangent taken near ground piercing end 18 that would be at 20 degrees.
In this patent document, the word "comprising" is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article "a" does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be one and only one of the elements.
It will be apparent to one skilled in the art that modifications may be made to the illustrated embodiment without departing from the spirit and scope of the invention as hereinafter defined in the Claims.
