A second guide is disposed in surrounding relation to the spindle and has axially extending guide grooves formed in an inner surface for sliding engagement with the spindle guide flutes and helically advancing guide flutes formed in its outer surface for engaging corresponding guide flutes formed in the inner surface of the worm gear. A first adjustable eccentric is coupled to the spindle for controlling the vertical movement thereof and a second adjustable eccentric is coupled to the second guide for selectively controlling its vertical movement.
