Cultivator tooth clamp

A clamp for mounting an agricultural implement to a square cross section tool bar, said implement being at times subject to transverse force components parallel to said bar and having a substantially planar mounting shank with opposite side edges, said clamp comprising:

• a. an L-shaped bracket having planar legs disposed at substantially a right dihedral angle, said bracket being adapted for mounting on said bar with said legs engaging adjacent side thereof;
• b. one of said legs having an elongated shank slot adjacent a free end thereof and sized to closely receive said shank, the longitudinal dimension of said slot extending parallel to the dihedral vertex common said legs;
• c. a retaining clip adapted to engage said shank;
• d. fastening means for joining said bracket, clip, and shank to said bar in clamped engagement;
• and
• e. keying means on said clip in cooperative engagement with said one leg free end and thereby resisting the pivoting of said implement about a horizontal axis perpendicular to said bar, said keying means being an elongated key slot formed on said clip adjacent one end thereof and sized to closely receive said one leg free end, said clip being mounted with said one leg free end received in said key slot.

In combination, a clamp, an agricultural implement and a square cross section bar, said clamp mounting said implement to said bar, said implement being at times subject to transverse force components parallel to said bar and having a substantially planar mounting shank with opposite parallel side edges and a bolt receiving aperture formed adjacent a free end thereof, said clamp being an angular bracket having one leg with a bolt receiving aperture adjacent a free end thereof, another leg having a slot adjacent a free end thereof for receiving said shank, and having a portion of said other leg projecting beyond said slot, said clamp being mounted on said tool bar with said legs engaging adjacent sides of said bar and said shank being received in said bracket slot and engaging a side of said bar opposite that engaged by said one leg, said shank aperture and said bracket aperture being aligned and receiving a bolt therethrough, the improvement comprising:

• a. a retaining clip mounted in contact with said shank;
• b. said clip having a clip slot closely receiving said other leg portion;
• c. said clip having laterally spaced flanges closely receiving said shank side edges therebetween;
• and
• d. said clip having a bolt receiving aperture spaced from said clip slot, said clip aperture being aligned with said shank aperture and said bracket aperture, said bolt being received through said apertures and a nut threaded on said bolt, whereby said retaining clip provides resistance against said implement pivoting about a horizontal axis perpendicular to said tool bar in response to said transverse force components.
