ABSTRACT:
Apparatus for securely locking tractor pin drive apparatus against unintended movement transverse to the movement of the paper being fed by the device comprising a split U-shaped clamping member surrounding an elongated support means carrying the tractor and secured to the tractor body. A flat sided, threaded, bolt having a cam release and locking lever attached to one end and an adjusting self-locking means secured to the other end thereof secures the ends of the U-shaped clamp together. Movement of the lever affords quick cam release of the tractor mechanism with respect to the transverse support by engaging and disengaging the clamp from the support. Adjustment of the bolt alters the degree of clamping force between the clamp and the support.
