Abstract
Abstract ELONGATED SPLICE SLEEVE FOR REINFORCING BARS DEVINED BY A SERIES OF GENERALLY ALIGNED WIRE COILS, EITHER HELICAL OR ANNULAR, ENGAGED WITH AND INTERCONNECTED BY GENERALLY LONGITUDINALLY EXTENDING WIRES WELDED THERETO. A COATING OF CEMENTITIOUS MATERIAL IS APPLIED ABOUT THE EXTERIOR OF THE WIRES FOR DEFINING A GROUT CONTAINING INTERIOR, WITH THE OVERALL SLEEVE BEING EITHER OF A CYLINDRICAL CONFIGURATION OR OF A CONDIGURATION TAPERING FROM A MAXIMUM DIAMETER AT THE CENTER THEREOF TO MINIMUM DIAMETERS AT THE OPPOSED ENDS. THE NECESSITY FOR THE CEMENTITIOUS COATING CAN BE AVOIDED BY A POSITIONING OF THE COILS IN DIRECT ENGAGEMENT WITH EACH OTHER.
