CONTINUOUSLY ADJUSTABLE BACK LASH FREE POWER TRANSFER MECHANISM

摘要

An improved adjustment mechanism for taking up back lash producing looseness due to normal wear and tear in the gear train of a back lash free power transfer mechanism. In construction the adjustment mechanism includes a pair of coacting rotatably mounted members operatively connected to the gear train of the power transfer mechanism and arranged such that rotation of one of these members causes corresponding rotation of the other member, in turn, realigning intermeshing gear teeth of the gear train to remove back lash producing gaps or play therebetween.
