Abstract
Abstract An improved combination of compact tractor and scoop attachment, in which pivotal movement of the scoop in its frame in each direction is limited, and in one direction is retained by automatically operable, easily releasable means which is arranged to isolate the mechanism from forces transmitted through the scoop. As shown, the scoop frame is designed to receive numerous different coupling arrangements for various vehicle hitches.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
241 words
A scoop attachment, adapted to be connected to the lifting hitch of a power vehicle, comprising, in combination: a scoop for loading, lifting, transporting, and dumping materials, having a closed back, closed ends, and a stop finger secured to the outer surface of said back between said ends, said finger including lower and rear stop faces and an upper latching face; a frame, including a cross member, rigid means projecting from said cross member in a first direction and including coupling means for receiving the hitch of the vehicle, and a pair of arms projecting from said cross member in a second direction toward said scoop; means movably connecting the ends of said scoop to said arms for pivotal movement therebetween; means rigid with said cross member and positioned to engage said stop faces of said stop finger in a predetermined pivoted position of said finger and said scoop in said frame, to limit said pivotal movement in a first sense and to prevent translational movement of said finger in a direction towards said frame; a latching blade resiliently pivoted to said frame for automatically and releasably engaging said latching surface of said stop finger in said predetermined position thereof, to prevent said pivotal movement in a second sense opposite to said first sense; and manually operable means for pivotally releasing said latching blade from engagement wit said finger, to thereby enable pivotal movement of said scoop in said second sense.
Claim 2
Dependent Claim

A scoop attachment, adapted to be connected to the lifting hitch of a power vehicle, comprising, in combination: a scoop for loading, lifting, transporting, and dumping materials, having a closed back, closed ends, and a stop finger secured to the outer surface of said back between said ends, said finger including lower and rear stop faces and an upper latching face; a frame, including a cross member, rigid means projecting from said cross member in a first direction and including coupling means for receiving the hitch of the vehicle, and a pair of arms projecting from said cross member in a second direction toward said scoop; means movably connecting the ends of said scoop to said arms for pivotal movement therebetween; means rigid with said cross member and positioned to engage said stop faces of said stop finger in a predetermined pivoted position of said finger and said scoop in said frame, to limit said pivotal movement in a first sense and to prevent translational movement of said finger in a direction towards said frame; a latching blade resiliently pivoted to said frame for automatically and releasably engaging said latching surface of said stop finger in said predetermined position thereof, to prevent said pivotal movement in a second sense opposite to said first sense; and manually operable means for pivotally releasing said latching blade from engagement wit said finger, to thereby enable pivotal movement of said scoop in said second sense.
Claim 3
Dependent Claim
63 words
The structure of claim 1, for use with a threepoint hitch having lower arms and an upper arm, in which the coupling means includes a pair of separate rigid members joined in an inverted Y-formation to receive the lower arms of said three-point hitch, near the base of the formation, and the upper arm of the hitch, near the apex of the formation.
Claim 4
Dependent Claim
56 words
The structure of claim 1 in which the coupling means includes a U-shaped member, means securing said member to said rigid means with the legs of said member vertically spaced and horizontally extending to receive a "one-point" vehicle hitch, and a pair of aligned apertures in said legs for passing the linch pin of said hitch.
Claim 5
Dependent Claim
89 words
The structure of claim 1 in which the coupling means is for connection to a manual lift vehicle hitch having lower arms and an upper arm, and includes laterally spaced central and outer rigid members, said central member extending vertically further than said outer members, means interconnecting the upper ends of said outer members to said central member and arranged for connection to the lower arms of a manual lift vehicle hitch, and means connecting the upper end of said central member to an upper arm of the hitch.
Claim 6
Dependent Claim
73 words
The structure of claim 1 in which said rigid means comprises two pairs of members, each pair including a short member and a long member inwardly spaced therefrom with aligned mounting holes in said members for engagement with the lower arms of a three-point hitch, said long members being upwardly convergent to the location of a further pair of aligned mounting holes for connecting said members to the upper arm of the hitch.
