ABSTRACT:
A system for connecting wall partitions or panels together wherein sets of two cross-drilled blind holes are formed in the ends of the partitions to be joined, one hole being of smaller diameter and opening on the end surface of the partition and the other hole of larger diameter opening on one of the side faces. The connector hardware involves three basic parts including a cylindrical plug member, in the larger diameter hole and has a threaded axial bore in one end and a communicating cross bore toward the other end, which bore also communicates with the smaller diameter hole. A second cylindrical connector member, is closely accommodated in the smaller diameter hole and in the cross bore of the plug member, and has a threaded axial bore in one end and a tapered groove or waist portion along its length. The third connector part constitutes a screw member that is adapted to be screwed into the axial bores in each of the cylindrical members. The screw member bridges the partition end surfaces when screwed into the axial bores in cooperating connector members in each partition and is provided with a cone point which, when the screw member is screwed, cooperates with the waist portion of the connector member in the cross bore to produce a camming action therebetween. This camming action draws together the respective end surfaces of the two partitions containing the cooperating sets of connector points.
