ABSTRACT:
A relatively inexpensive means for preventing the transmission of thread drunkenness to a carriage or other element being driven by a lead screw comprising a drive nut formed of a pair of half-nuts arranged to engage the thread of the lead screw. An intermediate member is connected to the half-nuts and to a carriage connector member to permit movement of the intermediate member relative to the connector member only by rotation about a pivot axis perpendicular to the axis of the lead screw and lying in a plane which extends between the half-nuts. The half-nuts are connected to the intermediate member to locate the intermediate member with respect to the half-nuts along the axis of the lead screw and to prevent rotation of the half-nuts about the lead screw axis, whereby uneven advance of the two half-nuts along the axis of the lead screw causes the intermediate member to rotate about the pivot axis to provide uniform motion along the lead screw axis to the connector member.
