Abstract
Abstract A tool bar clamp for connecting a standard of an earth-working toolholder to a support, as a tool bar of a cultivator. The clamp has a body with a passageway for receiving a portion of the standard. A first pair of nut and bolt assemblies, engageable with the forward edge of the standard, clamp the standard against the back of the body. A second pair of nut and bolt assemblies, mounted on the side of the body, clamp the side of the standard in the body to fix the lateral and perpendicular position of the standard in the clamp. The body is mounted on the support with a retainer and a pair of nut and bolt assemblies.
