Abstract
Abstract An excavating apparatus adapted for use with a grader, backhoe, loader or the like which includes an excavating implement supported from the end of a longitudinal member by an implement supporting means which is movable about a first pivot means having an axis extending in a direction transverse to the length of the longitudinal member. The excavating implement is mounted for movement about a second pivot means having an axis which extends in the plane of the longitudinal direction of the longitudinal member. The second pivot means extends between the implement supporting means and the lower part of the rear portion of the implement and this second pivot means is adjacent to the ground when the leading edge of the implement rests on the ground. The apparatus also includes means for moving the implement supporting means about the first pivot means and means for moving the implement about the second pivot means. In a preferred embodiment the means for moving the implement about the second pivot means includes a hydraulically operated reciprocating means, such as a cylinder and ram, which has one end pivotally attached to one of the excavating implement and the implement supporting means and the other end pivotally attached to the other of the implement and the implement supporting means. Also, preferably, at least the major portion of said means for moving the implement is located in the space between the rear portion of the excavating implement and the forward portion of the implement supporting means.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
191 words
In a device of the character described, a longitudinal member, a excavating implement, excavating implement supporting means for supporting said excavating implement, first pivot means connecting the outer end of said longitudinal member with the upper end of said implement supporting means for movement of said implement supporting means about an axis which is substantially transverse to the length of said longitudinal member, means comprising first hydraulically operated reciprocating means for moving said implement supporting means about said first pivot means, second pivot means for supporting said excavating implement for movement about an axis which extends in the same vertical plane as the longitudinal direction of said longitudinal member, said second pivot means extending between a lower part of said implement supporting means and a lower part of the rear portion of said implement when the leading edge of said implement rests on the ground, and the axis of said second pivot means being adjacent to and generally parallel to the ground line when the leading edge of said implement rests on the ground, and means comprising second hydraulically operated reciprocating means for moving said implement about said second pivot means.
Claim 2
Dependent Claim
191 words
In a device of the character described, a longitudinal member, a excavating implement, excavating implement supporting means for supporting said excavating implement, first pivot means connecting the outer end of said longitudinal member with the upper end of said implement supporting means for movement of said implement supporting means about an axis which is substantially transverse to the length of said longitudinal member, means comprising first hydraulically operated reciprocating means for moving said implement supporting means about said first pivot means, second pivot means for supporting said excavating implement for movement about an axis which extends in the same vertical plane as the longitudinal direction of said longitudinal member, said second pivot means extending between a lower part of said implement supporting means and a lower part of the rear portion of said implement when the leading edge of said implement rests on the ground, and the axis of said second pivot means being adjacent to and generally parallel to the ground line when the leading edge of said implement rests on the ground, and means comprising second hydraulically operated reciprocating means for moving said implement about said second pivot means.
Claim 3
Dependent Claim
43 words
A device according to claim 1 wherein at least the major portion of said means for moving said implement about said second pivot means is positioned between the rear portion of said excavating implement and the forward portion of said implement supporting means.
Claim 4
Dependent Claim
50 words
A device according to claim 1 wherein the axis of said second pivot means is located between the longitudinal center line of said excavating implement and the leading edge thereof when the implement is viewed from the front and when the leading edge of said implement rests on the groUnd.
Claim 5
Dependent Claim
58 words
A device according to claim 1 wherein said means for moving said implement supporting means about said first pivot means comprises a link having one end pivotally attached to said first hydraulically operated reciprocating means and its other end pivotally attached to said implement supporting means at a locality which is between said first and second pivot means.
Claim 6
Dependent Claim
47 words
A device according to claim 1 wherein said first pivot means is located adjacent to the upper end of said implement supporting means and the axis of said second pivot means is normal to said implement supporting means and is located adjacent to the lower end thereof.
Claim 7
Dependent Claim
94 words
A device according to claim 1 wherein said means for moving said implement supporting means about said first pivot means comprises a link having one end pivotally attached to said first hydraulically operated reciprocating means and its other end pivotally attached to said implement supporting means at a locality which is between said first and second pivot means, the distance between said first pivot means and the pivotal attachment of said link to said implement supporting means being greater than the distance between said pivotal attachment of said link and said second pivot means.
Claim 8
Dependent Claim
77 words
A device according to claim 1 wherein said means for moving said implement about said second pivot means comprises third pivot means for attaching one of its ends to said implement supporting means and fourth pivot means for attaching its other end to said excavating implement and said third and fourth pivot means are located between the axis of said first pivot means and said second pivot means when said excavating implement is viewed from the front.
Claim 9
Dependent Claim
31 words
A device according to claim 1 wherein said excavating implement and said second hydraulically operated reciprocating means are rotatable to be positioned beneath the longitudinal member during the earth excavating operation.
Claim 10
Dependent Claim
46 words
A device according to claim 1 wherein said longitudinal member is supported from a vehicle and wherein said implement and said second hydraulically operated reciprocating means are rotatable to be positioned between said means for supporting said excavating implement and said vehicle during the excavating operation.
