Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
205 words
An apparatus for selectively and rigidly connecting a tool bar to a propelling vehicle hitch mechanism having upper and lower surfaces comprising an elongated body having a longitudinal axis located between upper and lower surfaces, first and second hitch engaging means located adjacent one end of said body and tool bar mounting means located adjacent the other end thereof, said first and second hitch engaging means being vertically spaced outwardly from and on opposite sides of the longitudinal axis of said body for selective engagement with the hitch mechanism, said tool bar mounting means being located so that the longitudinal axis of said tool bar is vertically spaced from the longitudinal axis of said body and between said upper and lower surfaces thereof, first clamping means for connecting a selected one of said hitch engaging means to one of said upper and lower surfaces of the hitch mechanism, and second clamping means for connecting said tool bar to said tool bar mounting means, whereby said tool bar may be selectively disposed at a plurality of elevations when said apparatus is engaged with the upper surface of the hitch mechanism and an additional plurality of elevations when engaged with the lower surface of the hitch mechanism.
Claim 2
Independent Claim
205 words
An apparatus for selectively and rigidly connecting a tool bar to a propelling vehicle hitch mechanism having upper and lower surfaces comprising an elongated body having a longitudinal axis located between upper and lower surfaces, first and second hitch engaging means located adjacent one end of said body and tool bar mounting means located adjacent the other end thereof, said first and second hitch engaging means being vertically spaced outwardly from and on opposite sides of the longitudinal axis of said body for selective engagement with the hitch mechanism, said tool bar mounting means being located so that the longitudinal axis of said tool bar is vertically spaced from the longitudinal axis of said body and between said upper and lower surfaces thereof, first clamping means for connecting a selected one of said hitch engaging means to one of said upper and lower surfaces of the hitch mechanism, and second clamping means for connecting said tool bar to said tool bar mounting means, whereby said tool bar may be selectively disposed at a plurality of elevations when said apparatus is engaged with the upper surface of the hitch mechanism and an additional plurality of elevations when engaged with the lower surface of the hitch mechanism.
Claim 3
Dependent Claim
60 words
The structure of claim 1 in which said body includes a pair of vertically disposed and generally parallel side members connected by first and second spacer means, said first spacer means being relatively horizontally disposed and connecting said side members adjacent said one end, and said second spacer means being disposed between said side members adjacent the other end thereof.
Claim 4
Dependent Claim
37 words
The structure of claim 2 in which said first and second hitch engaging means are mounted to a pronged hitch mechanism disposed between said side members and relatively spaced adjacent either side of said second spacer means.
Claim 5
Dependent Claim
32 words
The structure of claim 1 in which said first and second hitch engaging means include first and second draw bar engaging recesses disposed along the upper and lower surface of said body.
Claim 6
Dependent Claim
35 words
The structure of claim 4 in which said tool bar mounting means is located so that the longitudinal axis of said tool bar is in substantially horizontal alignment with said first draw bar engaging recess.
Claim 7
Dependent Claim
41 words
The structure of claim 1 in which said tool bar engaging means is disposed at substantially a 45* angle with the longitudinal axis of said body and extends generally downwardly and forwardly from the upper surface toward the lower surface thereof.
