Title: Richard L. Gottorff: Tubing and End-Fitting Assembly Innovations

Introduction

Richard L. Gottorff is an inventor associated with Rochester, New York, and ITT Corporation. His patent work focuses on joining tubing to threaded end fittings through an interference-fit assembly and precision machining process. He is credited with 2 patents.

Latest Patents

Gottorff’s listed patents include “Method for a Unitary Assembly of Tubing and a Pressed-On, Interference Fit” and “Unitary Assembly of Tubing and a Pressed-On, Interference Fit.” Both describe a tubing-and-end-fitting assembly designed to create a secure connection.

The end fitting has a threaded fastener and a through-bore with a conical transition where the bore narrows. One end of the tubing is impacted, expanded, and sized to form an interference fit. The unexpanded portion is inserted through the larger bore and past the transition, while the expanded portion is pressed into the narrower bore until fully seated.

The assembly is then machined coaxially with a five-step tool. The tool restores the tube’s inside diameter where forming reduced it, swages the expanded tube into the fitting, and machines the female pilot land, O-ring gland, and thread lead. Together, these steps describe a method for producing a fitted and finished tubing connection.

Career Highlights

Gottorff’s documented patent contributions center on the design and manufacture of tubing assemblies with pressed-on interference-fit end fittings. The described process combines tube-end forming, controlled insertion, and multiple machining operations.
