Swivel nut assembly

A swivel nut assembly comprises a nut having a pair of opposite sides with a threaded opening extending between and transversely of said opposite sides, said nut comprising a pair of U-shaped disks with each said disk having a first leg, a second leg, and a base interconnecting said legs, means pivotally interconnecting said first legs of said disks so that said disks can be pivoted relative to one another between an open position and a closed position, each said disk forming a U-shaped recess with the portion of the recess formed by said base having at least one screw thread therein, wherein the improvement comprises that the first and second legs of each said disk defines the opposite sides of said U-shaped recess in said disk, said disks in the open position have said second legs disposed in laterally spaced relation and in the closed position have said second legs disposed in overlapping contacting relation with the threaded bases in said U-shaped recesses forming the threaded opening through said nut and with the second legs extending from said bases in the circumferential direction of the threaded opening, each said U-shaped disk having a first face directed toward the other said U-shaped disk and a second face directed away from the other said U-shaped disk with said first and second faces extending transversely of the axial direction of the threaded opening and defining an edge of the threaded opening, each said disk having an extension projecting from the first face thereon in the direction of the axis of the threaded opening through said nut toward the second face on the other said disk with each said extension having surfaces thereon extending in the axial direction of the threaded opening disposed in contacting engagement with similarly extending surfaces on the first and second legs on the other said disk when said disks are in closed position and in the closed position of said disks a portion of each of said U-shaped recesses combining to form the threaded opening through said nut, each of said extensions extend in the axial direction of the threaded opening at least in part from said base on said disk from which the extension projects, each said extension having a surface extending in the axial direction of the threaded opening in said nut and forming a continuation of the threaded surface of said base in said U-shaped recess and said surface on said extension forming a continuation of the threaded surface of said base and having at least one screw thread thereon forming a continuation of the at least one screw thread in the portion of said U-shaped recess formed by said base.
