Abstract: This invention provides a method for producing an internally threaded part through a stamping operation in one embodiment of which a die is provided with a curvature greater than that of the completed part. A punch is provided having ridges thereon collectively complementary in cross section to a thread to be produced and of a curvature slightly less than that of said cavity in said die, and a workpiece is engaged by said punch so as to force it against the die and form grooves in the workpiece the full depth of the thread to be produced, after which the workpiece is given a cylindrical shape, bringing the ends of the grooves into registry so as to provide an internally threaded part. Only a single stroke normally is required in forming the grooves.

Abstract: This invention provides a bracket adapted to hold cables or the like, the bracket being a unitary member that includes a longitudinally split internally threaded sleeve from one end of which is a connecting element that extends to the side edge of a flat plate having end flanges defining slots to receive a banding strap, and side flanges extending between the end flanges for providing strength and rigidity.

Abstract: This invention provides a stuffing tube for the decks and bulkheads of ships, which includes a tubular body having portions of two diameters interconnected by a tapered shoulder. An adapter having a tapered portion complementary to that of the tubular body fits inside, the adapter having a short cylindrical section dimensioned to fit over the cable. A seal comprising a strip of resilient material with an annealed wire core is wrapped around the cable and one end of it is engaged within the tapered adapter. The opposite end is engaged by a flat washer which has an inside diameter comparable to that of the cylindrical section of the adapter. A gland nut compresses the seal, pressing inwardly on the flat washer. Different cable sizes are accommodated within a single tubular body by varying the dimensions of the adapter, seal and flat washer.
