Abstract
Abstract The invention comprises an implement mounting arrangement having lifting and angling capability. Such an arrangement is useful, for example, for motivating a blade attached to the front of a bulldozer. The arrangement includes a support structure mountable to a tractor. Extending forwardly from the support structure are a pair of substantially horizontal frame members elevationally spaced from one another. One end of each of the members is mounted to pivot vertically from the structure. An implement, such as a bulldozer blade, generally centrally communicates in a universally pivotable manner to the other end of each of the members. An element of adjustable length, such as a hydraulic cylinder which is coplanar with one of the members and is horizontally pivotably coupled at one end thereof to said of one of said members, forms a part of the arrangement. The element is universally pivotably coupled at the other end thereof to the implement at a position thereon spaced away from the center thereof. Thus, it is possible to angle the implement by changing the horizontal angle between it and the support structure. A lifter forms yet another part of the arrangement. The lifter is of adjustable length and is vertically pivotably mounted at one end thereof to the structure at one elevation, and at the other end thereof to the implement at another elevation. Extension and contraction of the lifter serves to move the implement substantially vertically.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
168 words
An implement mounting arrangement having lifting and angling capability, comprising: a support structure mountable to a vehicle; a pair of substantially horizontal frame members elevationally spaced from one another, one end of each of said members being mounted to pivot vertically from a side of said structure removed from said vehicle; an implement communicating generally in the center thereof in a universally pivotal manner to the other end of each of said members; an element of adjustable length generally coplanar with one of said members horizontally pivotally coupled at one end thereof to said one of said members and universally pivotally coupled at the other end thereof to said implement spaced away from the center thereof to angle said implement by changing the horizontal angle between said implement and said structure; and a lifter of adjustable length vertically pivotally mounted at one end thereof to said structure at one elevation and at the other end thereof to said implement at another elevation to move said implement substantially vertically.
Claim 2
Dependent Claim
168 words
An implement mounting arrangement having lifting and angling capability, comprising: a support structure mountable to a vehicle; a pair of substantially horizontal frame members elevationally spaced from one another, one end of each of said members being mounted to pivot vertically from a side of said structure removed from said vehicle; an implement communicating generally in the center thereof in a universally pivotal manner to the other end of each of said members; an element of adjustable length generally coplanar with one of said members horizontally pivotally coupled at one end thereof to said one of said members and universally pivotally coupled at the other end thereof to said implement spaced away from the center thereof to angle said implement by changing the horizontal angle between said implement and said structure; and a lifter of adjustable length vertically pivotally mounted at one end thereof to said structure at one elevation and at the other end thereof to said implement at another elevation to move said implement substantially vertically.
Claim 3
Dependent Claim
77 words
An arrangement as in claim 1, including a longitudinally slidable mechanism adjacent said implement, said mechanism carrying a universal joint thereon which communicates in said universally pivotal manner with said other of said members and said implement, the longitudinal movement of said mechanism providing horizontal movement to said universal joint, said mechanism connecting said implement and the other end of the other of said members to provide a capability for coordinated angling and tilting of said implement.
Claim 4
Dependent Claim
77 words
An arrangement as in claim 1, including a longitudinally slidable mechanism adjacent said implement, said mechanism carrying a universal joint thereon which communicates in said universally pivotal manner with said one of said members and said implement, the longitudinal movement of said mechanism providing horizontal movement to said universal joint, said mechanism connecting said implement and the other end of said one of said members to provide a capability for coordinated angling and tilting of said implement.
Claim 5
Dependent Claim
44 words
An arrangement in claim 1, further characterized in that each of said members comprises a V-shaped frame, the legs thereof comprise the one ends thereof and the apexes thereof comprise the other ends thereof, said V-shaped frames being generally parallely aligned with one another.
Claim 6
Dependent Claim
95 words
An arrangement as in claim 4, including a second element of adjustable length generally coplanar with said one of said V-shaped frames horizontally pivotably coupled at one end thereof to said one of said V-shaped frames and universally pivotally coupled at the other end thereof to said implement symmetrically to the spacing of said other end of said first element, the one end of each of said elements being horizontally pivotally coupled to the respective proximate legs of said one of said V-shaped frames, the lengths of said first and second elements being coordinatedly adjustable.
Claim 7
Dependent Claim
31 words
An arrangement as in claim 5, further characterized in that said other ends of said first and second elements are further separated from one another than are said one ends thereof.
Claim 8
Dependent Claim
22 words
An arrangement as in claim 6, wherein said first element, said second element and said lifter each comprise an extensible hydraulic cylinder.
Claim 9
Dependent Claim
87 words
An arrangement as in claim 7, including a longitudinally slidable mechanism adjacent said implement, said mechanism carrying a universal joint thereon which communicates in said universally pivotal manner with said other of said members and said implemment, the longitudinal movement of said mechanism providing horizontal movement to said universal joint, said mechanism connecting said implement and the apex of said other of said V-shaped frames of said other of said members to provide a capabIlity for coordinated angling and tilting of said implement relative to said structure.
Claim 10
Dependent Claim
87 words
An arrangement as in claim 7, including a longitudinally slidable mechanism adjacent said implement, said mechanism carrying a universal joint thereon which communicates in said universally pivotal manner with said one of said members and said implement, the longitudinal movement of said mechanism providing horizontal movement to said universal joint, said mechanism connecting said implement and the apex of said one of said V-shaped frames of said one of said members to provide a capability for coordinated angling and tilting of said implement relative to said structure.
