Abstract
An automatic clutch lock out and clutch release mechanism for package tying machines of the type utilizing handles or foot pedals to initiate a machine cycle. The automatic clutch lock out mechanism includes a cam gear rotatably mounted atop the forked clutch lever and a wedge-shaped release rack lever controllably operated by the tying machine's foot pedal or handle and which both meshes with the cam gear and slidably engages the associated cam follower lever, the combination of the two effecting gradual, quiet, and smooth engagement of the machine's clutch at the beginning of a tying cycle and further providing a safe and inexpensive clutch lock out that eliminates unreliable electrical components.
