Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
190 words
A hitch assembly for coupling a vehicle and a ground treating implement, said hitch comprising: a first frame member adapted to be fastened to the rear of said vehicle; a second frame member pivotally attached to said first frame member; means having one end attached to said first frame member and an opposite end attached to said implement and operable when actuated to exert a downward force on said implement to thereby pivot said implement about said pivotal attachment between said implement and said second frame to thereby transfer a portion of the weight of said vehicle to said implement; said last mentioned means comprising a fluid cylinder having one end pivotally fastened to said first frame member and a rod pivotally attached to said implement; a motor and a fluid pump carried by said hitch assembly for extending said fluid cylinder; a pair of spaced vertically extending hollow frame members ''''adapted to be attached to said vehicle,'''' said first frame member of said hitch assembly includes leg members adapted to be received in said hollow frame members; and means for locking said leg members in said hollow frame members.
Claim 2
Dependent Claim
190 words
A hitch assembly for coupling a vehicle and a ground treating implement, said hitch comprising: a first frame member adapted to be fastened to the rear of said vehicle; a second frame member pivotally attached to said first frame member; means having one end attached to said first frame member and an opposite end attached to said implement and operable when actuated to exert a downward force on said implement to thereby pivot said implement about said pivotal attachment between said implement and said second frame to thereby transfer a portion of the weight of said vehicle to said implement; said last mentioned means comprising a fluid cylinder having one end pivotally fastened to said first frame member and a rod pivotally attached to said implement; a motor and a fluid pump carried by said hitch assembly for extending said fluid cylinder; a pair of spaced vertically extending hollow frame members ''''adapted to be attached to said vehicle,'''' said first frame member of said hitch assembly includes leg members adapted to be received in said hollow frame members; and means for locking said leg members in said hollow frame members.
Claim 3
Dependent Claim
145 words
A hitch assembly for coupling a vehicle and a ground treating implement, said hitch comprising: a first frame member adapted to be fastened to the rear of said vehicle; a second frame member pivotally attached to said first frame member; means having one end attached to said first frame member and an opposite end attached to said implement and operable when actuated to exert a downward force on said implement to thereby pivot said implement about said pivotal attachment between said implement and said second frame to thereby transfer a portion of the weight of said vehicle to said implement; a pair of spaced vertically extending hollow frame members ''''adapted to be attached to said vehicle,'''' said first frame member of said hitch assembly includes leg members received in said hollow frame members; and means for locking said leg members in said hollow frame members.
Claim 4
Dependent Claim
145 words
A hitch assembly for coupling a vehicle and a ground treating implement, said hitch comprising: a first frame member adapted to be fastened to the rear of said vehicle; a second frame member pivotally attached to said first frame member; means having one end attached to said first frame member and an opposite end attached to said implement and operable when actuated to exert a downward force on said implement to thereby pivot said implement about said pivotal attachment between said implement and said second frame to thereby transfer a portion of the weight of said vehicle to said implement; a pair of spaced vertically extending hollow frame members ''''adapted to be attached to said vehicle,'''' said first frame member of said hitch assembly includes leg members received in said hollow frame members; and means for locking said leg members in said hollow frame members.
Claim 5
Dependent Claim
191 words
In combination with a vehicle, a hitch assembly for coupling the vehicle to a ground treating implement, said hitch comprising; a first frame member adapted to be fastened to the rear of said vehicle; a second frame member pivotally attached to said first frame member; means having one end attached to said first frame member and an opposite end attached to said implement and operable when actuated to exert a downward force on said implement to thereby pivot said implement about said pivotal attachment between said implement and said second frame to thereby transfer a portion of the weight of said vehicle to said implement; said last mentioned means comprising a fluid cylinder having one end pivotally fastened to said first frame member and a rod pivotally attached to said implement; a motor and a fluid pump carried by said hitch assembly for extending said fluid cylinder; said vehicle being provided with a pair of spaced vertically extending hollow frame members and said first frame member of said hitch assembly including leg members received in said hollow frame members, and means for locking said leg members in said hollow frame members.
Claim 6
Dependent Claim
191 words
In combination with a vehicle, a hitch assembly for coupling the vehicle to a ground treating implement, said hitch comprising; a first frame member adapted to be fastened to the rear of said vehicle; a second frame member pivotally attached to said first frame member; means having one end attached to said first frame member and an opposite end attached to said implement and operable when actuated to exert a downward force on said implement to thereby pivot said implement about said pivotal attachment between said implement and said second frame to thereby transfer a portion of the weight of said vehicle to said implement; said last mentioned means comprising a fluid cylinder having one end pivotally fastened to said first frame member and a rod pivotally attached to said implement; a motor and a fluid pump carried by said hitch assembly for extending said fluid cylinder; said vehicle being provided with a pair of spaced vertically extending hollow frame members and said first frame member of said hitch assembly including leg members received in said hollow frame members, and means for locking said leg members in said hollow frame members.
